Description of Embodiments

(First Embodiment)

[0007] With reference to FIGS. 1 to 10, a function module 1 of the present embodiment will be described below.

[0008] As illustrated in FIG. 1 the function module 1 according to the present disclosure includes a function housing 3 and an operation housing 2. The function module 1 shown in FIG. 1 is provided with a battery pack 4. The function module 1 according to the present embodiment further includes a handle 5. The function module 1 is not limited to this embodiment but can be various types of apparatuses having portability and transportability.

[0009] The function housing 3 includes a functioning section 33 configured to perform a main function of the function module 1. In the present embodiment, the functioning section 33 is an illuminator 331. Thus, the function module 1 according to the present embodiment is a lighting device. The function housing 3 has a first surface 31 and a second surface 32 on both sides in a thickness direction of the function housing 3. The function housing 3 further includes the illuminator 331 whose light-emitting surface is the first surface 31. That is, the light-emitting surface of the illuminator 331 is the first surface 31 which is one of the both surfaces in the thickness direction of the function housing 3. The illuminator 331 outputs light from the first surface 31. The first surface 31 and the second surface 32 are rectangular.

[0010] The illuminator 331 includes a light source unit 332 and a light transmitting plate 333. The light source unit 332 includes: a metal substrate 334 made of, for example, aluminum or the like; and a plurality of light emitting diode (LED) modules 335. The light source unit 332 is supplied with electric power from the battery pack 4 to emit light. The light transmitting plate 333 has transparency such that the light emitted from the light source unit 332 is transmitted. The light transmitting plate 333 is attached to the function housing 3 to form the first surface 31. The light source unit 332 is accommodated in the function housing 3 at a location corresponding to the light transmitting plate 333.

[0011] As illustrated in FIG. 2, the second surface 32 of the function housing 3 is provided with a heat dissipator 34 which is to be thermally coupled to the illuminator 331. That is, the second surface 32 on an opposite side from the first surface 31 in the thickness direction of the function housing 3 is the heat dissipator 34 to which heat generated from the illuminator 331 is transmitted and which is configured to dissipate the heat. In the function module 1 according to the present embodiment, the heat dissipator 34 facilitates dissipation of heat generated from the light source unit 332 of the illuminator 331, which enables the thermal degradation of the light source unit 332 to be reduced. Examples of the thermal coupling between the illuminator 331 and the heat dissipator 34 include a coupling mode in which the illuminator 331 and the heat dissipator 34 are in contact with each other, a mode in which the illuminator 331 and the heat dissipator 34 face each other with a gap therebetween, and a mode in which a thermally conductive member is present between the illuminator 331 and the heat dissipator 34.

[0012] The heat dissipator 34 has an uneven shape 340 formed on the second surface 32. That is, the heat dissipator 34 has the uneven shape 340 including a recess 341 and a projection 342 formed on the second surface 32. The recess 341 is recessed with respect to the projection 342 in the thickness direction of the function housing 3. That is, the projection 342 protrudes beyond the recesses 341 in the thickness direction of the function housing 3. When the heat dissipator 34 has the uneven shape formed on the second surface 32, the surface area of the heat dissipator 34 can be increased, and the heat dissipation characteristic of the heat dissipator 34 can be improved as compared to a case where the heat dissipator 34 has no uneven shape. The heat dissipator 34 preferably includes a plurality of the recesses 341 and a plurality of the projections 342. In the heat dissipator 34 including the plurality of recesses 341 and the plurality of projections 342, the surface area of the heat dissipator 34 can be increased, and the heat dissipation characteristic of the heat dissipator 34 can be improved as compared to a case of a single recess 341 and a single projection 342.

[0013] The uneven shape 340 includes a linear part extending in a direction orthogonal to a first rotation axis X. That is, the heat dissipator 34 has the uneven shape 340 which is linear and which extends in the direction orthogonal to the first rotation axis X. The function housing 3 rotates, as described later, about the first rotation axis X, thereby moving between a closed position and an open position, and the uneven shape 340 has the recess 341 and the projection 342 which extend in a direction orthogonal to the first rotation axis X. The uneven shape 340 is formed on the second surface 32, and thus, the uneven shape 340 can reinforce the second surface 32 of the function housing 3. Thus, the strength of the function housing 3 can be improved. In addition, since the uneven shape 340 extends in the direction orthogonal to the first rotation axis X, force applied to the function housing 3 is easily dispersed in a direction orthogonal to the rotation direction of the function housing 3 when the function housing 3 is rotated about the first rotation axis X. Thus, the uneven shape 340 enables reinforcement effect of reinforcing the function housing 3 to be improved.

[0014] The operation housing 2 includes an operation section 23 for operation of the functioning section 33. In the function module 1 according to the present embodiment, since the functioning section 33 is the illuminator 331, the illuminator 331 is operated via the operation section 23. For example, an operation given to the operation section 23 enables the illuminator 331 to be turned on, off, and dimmed. The operation housing 2 accommodates a circuit unit including a lighting circuit configured to turn on the light source unit and a controller configured to control the lighting circuit.

[0015] The operation section 23 is located on an opposite surface of the operation housing 2 from the battery pack 4. That is, the operation section 23 is exposed on a surface opposite from a specific plane 24 of the operation housing 2, the battery pack 4 being to be attached to the specific plane 24. As described later, the specific plane 24 is a first surface 21 in a thickness direction of the operation housing 2. Thus, the operation section 23 is located on a second surface 22 in the thickness direction of the operation housing 2. That is, the operation section 23 is provided on the second surface 22 of the operation housing 2 which faces the second surface 32 of the function housing 3 in a state where the function housing 3 is in the closed position. Thus, in the state where the function housing 3 is in the closed position, the operation section 23 is covered with the operation housing 2 and is thus difficultly operated, but in a state where the function housing 3 is in the open position, the operation section 23 is not covered with the operation housing 2 and is thus easily operated. Note that the "closed position" and the "open position" will be described later.

[0016] Examples of the operation section 23 include a push button and a touch panel.

[0017] The operation section 23 is provided in a recess 231 formed on the opposite surface of the operation housing 2 from the battery pack 4. That is, operation section 23 is provided in the recess 231 formed in the second surface 22 of the operation housing 2. The operation section 23 is exposed in the recess 231. The recess 231 is recessed with respect to a portion other than the recess 231 in the second surface 22. Thus, as compared to a case where the operation section 23 is provided on the portion other than the recess 231 in the second surface 22, the operation section 23 is less likely to be unexpectedly touched by, for example, a hand of a person or an object. Thus, the operation section 23 is less likely to be accidentally operated, and, for example, when the function housing 3 is rotated about the first rotation axis X, erroneous operation of the operation section 23 is reduced.

[0018] The operation housing 2 has one end in a prescribed direction S provided with a first support 61. In other words, one direction of directions transverse to the thickness direction of the operation housing 2 is defined as the prescribed direction S, and the first support 61 is located at one end of the operation housing 2 in the prescribed direction S. The first support 61 includes a plurality of (e.g., two) couplers 611. The plurality of couplers 611 protrudes at the one end of the operation housing 2. Moreover, the plurality of couplers 611 are aligned in a direction along the first rotation axis X at the one end of the operation housing 2. Thus, the plurality of couplers 611 face each other in a direction along the first rotation axis X at the one end of the operation housing 2.

[0019] The function housing 3 is supported on the operation housing 2 by the first support 61 in a state where the function housing 3 is rotatable about the first rotation axis X along a direction transverse to the prescribed direction S. That is, the first support 61 of the operation housing 2 supports the function housing 3, and the function housing 3 is in the state where the function housing 3 is rotatable about the first rotation axis X along the direction transverse to the prescribed direction S.

[0020] The function housing 3 is supported by the operation housing 2 via a second support 62. That is, the second support 62 is attached to the first support 61, and the operation housing 2 is attached to the second support 62. The second support 62 is attached to the first support 61 to be rotatable about the first rotation axis X. Thus, along rotation of the second support 62 about the first rotation axis X with respect to the first support 61, the function housing 3, together with the second support 62, also rotates about the first rotation axis X with respect to the first support 61.

[0021] The second support 62 includes a shaft 621 which is to be attached to the first support 61 and a base 622 to which the function housing 3 is to be attached. The shaft 621 has a cylindrical shape elongated in a direction along the first rotation axis X. The shaft 621 protrudes at one end of the base 622, and on an opposite side from a protrusion direction in which the shaft 621 protrudes from the base 622, the function housing 3 is attached to the base 622. The shaft 621 is disposed between the plurality of couplers 611 facing each other. Moreover, the shaft 621 has both end each connected to a corresponding one of the couplers 611 to be rotatable about the first rotation axis X. That is, the function housing 3 and the operation housing 2 are connected to each other via a hinge mechanism including the first support 61 and the second support 62.

[0022] The function housing 3 rotates about the first rotation axis X, thereby moving between a closed position and an open position. That is, the function housing 3 is rotatable about the first rotation axis X between a state where the function housing 3 is in the closed position (see FIG. 1) and a state where the function housing 3 is in the open position (see FIG. 2). Here, the "closed position" is, as illustrated in FIG. 1, a position in which the function housing 3 overlaps the operation housing 2 in the thickness direction of the function housing 3. That is, the "closed position" is a position achieving a state where the second surface 32 of the function housing 3 faces the second surface 22 of the operation housing 2 in the thickness direction of the function housing 3. That is, in a state where the thickness direction of the function housing 3 coincides with the thickness direction of the operation housing 2, a state is achieved where the function housing 3 is in the closed position with respect to the operation housing 2. Thus, when the function housing 3 rotates about the first rotation axis X to reach the closed position, a state is achieved where the second surface 32 and the second surface 22 face each other in the thickness direction of the function housing 3. Moreover, the "open position" is, as illustrated in FIG. 2, a position in which a state is achieved where the function housing 3 and the operation housing 2 do not overlap each other in the thickness direction of the function housing 3. That is, the "closed position" is a position achieving a state where the second surface 32 of the function housing 3 does not face the second surface 22 of the operation housing 2 in the thickness direction of the function housing 3. That is, in a state where the thickness direction of the function housing 3 does not coincide with the thickness direction of the operation housing 2, a state is achieved where the function housing 3 is in the open position with respect to the operation housing 2. Thus, when the function housing 3 rotates about the first rotation axis X to reach the open position, a state is achieved where the second surface 32 and the second surface 22 do not face each other in the thickness direction of the function housing 3.

[0023] In the function module 1 according to the present embodiment, the open position of the function housing 3 is determined such that the angle between the second surface 32 of the function housing 3 and the second surface 22 of the operation housing 2 is 270 degrees at the maximum. In the function module 1 according to the present embodiment, a plurality of open positions of the function housing 3 are stepwise determined. For example, for the open position of the function housing 3, open positions, namely, 36 degrees, 72 degrees, 90 degrees, 120 degrees, 180 degrees, and 270 degrees, are stepwise determined for the angle between the second surface 32 of the function housing 3 and the second surface 22 of the operation housing 2. As described above, the first support 61 and the second support are couple to each other such that the function housing 3 is held at the plurality of open positions. The second support is preferably coupled via, for example, a notch structure to the first support 61 such that the function housing 3 is held at the plurality of open positions.

[0024] In the function module 1 according to the present embodiment, rotating the function housing 3 about the first rotation axis X enables the orientation of the function housing 3 to be changed, along which the orientation of the illuminator 331 can also be changed. Thus, in the function module 1 according to the present embodiment, a light irradiation direction from the light irradiation area of the illuminator 331 around the first rotation axis X can be changed to change a direction in which light brightly shines.

[0025] As illustrated in FIG. 3, the function housing 3 is supported by the operation housing 2 in a state where the function housing 3 is rotatable about a second rotation axis Y transverse to the first rotation axis X. That is, the operation housing 2 supports the function housing 3 in a state where the function housing 3 is rotatable about the first rotation axis X and also in a state where the function housing 3 is rotatable about the second rotation axis Y. Thus, the function housing 3 is rotatable about both the first rotation axis X and the second rotation axis Y with respect to the operation housing 2.

[0026] The second rotation axis Y is provided to the second support 62 rotatably attached to the operation housing 2 via the first support 61. That is, the second support 62 is attached to the first support 61 provided to the operation housing 2 to be rotatable about the first rotation axis X, and the second support 62 has the second rotation axis Y. The function housing 3 has one end attached to the base 622, and thus, the function housing 3 is supported by the second support 62. Therefore, the one end of the function housing 3 is attached to the base 622 to be rotatable about the second rotation axis Y. In the function module 1 according to the present embodiment, a plurality of angles of rotation of the function housing 3 rotatable about the second rotation axis Y are stepwise determined. For example, the angles of rotation of the function housing 3 are stepwise held such that the orientation of the functioning section 33 of the function housing 3 is at, for example, 36 degrees, 72 degrees, 90 degrees, 120 degrees, and 180 degrees with respect to the prescribed direction S. In this case, similarly to the first support 61, the second support 62 is also provided with a notch mechanism.

[0027] In the function module 1 according to the present embodiment, rotating the function housing 3 about the second rotation axis Y enables the orientation of the function housing 3 to be changed, along which the orientation of the illuminator 331 can also be changed. Thus, in the function module 1 according to the present embodiment, a light irradiation direction from the light irradiation area of the illuminator 331 around the second rotation axis Y can be changed to change a direction in which light brightly shines.

[0028] As illustrated in FIG. 4, in the function module 1 according to the present embodiment, the operation housing 2 fits inside a projection plane M of the function housing 3 in plan view in a state where the function housing 3 is in the closed position. The projection plane M is rectangular. That is, in a state where the function housing 3 and the operation housing 2 overlap each other in the thickness direction of the function housing 3, the second surface 22 of the operation housing 2 is inside the projection plane M of the function housing 3 when the function module 1 is viewed from the first surface 31 of the function housing 3. Thus, in a state where the function housing 3 is in the closed position, a state is achieved where the second surface 22 of the operation housing 2 is covered with the function housing 3 and is thus not exposed.

[0029] As illustrated in FIGS. 5 and 6, the function module 1 according to the present embodiment has a gap 7 between the heat dissipator 34 and the operation housing 2 in a state where the function housing 3 is in the closed position. That is, the function housing 3 overlaps the operation housing 2 in the thickness direction of the function housing 3 such that the gap 7 is formed between the heat dissipator 34 and the operation housing 2. When the heat dissipator 34 has the uneven shape 340, the gap 7 is formed between a tip end of the projection 342 of the heat dissipator 34 and the second surface of the operation housing 2. That is, the gap 7 is between the second surface 32 and the second surface 22 in a state where the second surface 32 of the function housing 3 including the heat dissipator 34 faces the second surface 22 of the operation housing 2.

[0030] Also in a state where the function housing 3 is in the closed position, the gap 7 makes it difficult for heat to be transmitted from the heat dissipator 34 to the second surface 22 of the operation housing 2. Thus, heat is easily released through the gap 7 to the outside of the function module 1, and therefore, heat dissipation characteristic derived from the heat dissipator 34 is less likely to be degraded, and the influence of heat generated from the illuminator 331 over the operation housing 2 and/or the battery pack 4 can be reduced.

[0031] The function module 1 according to the present embodiment has elastic bodies 8 between the heat dissipator 34 and the operation housing 2 in a state where the function housing 3 is in the closed position. That is, the function housing 3 overlaps the operation housing 2 in the thickness direction of the function housing 3 such that the elastic bodies 8 are located between the heat dissipator 34 and the operation housing 2. Thus, in a state where the second surface 32 of the function housing 3 and the second surface 22 of the operation housing 2 face each other in the thickness direction of the function housing 3, the elastic bodies 8 are located between the second surface 32 of the function housing 3 and the second surface 22 of the operation housing 2.

[0032] Examples of the elastic body 8 include rubber, elastomer, plastic, and a spring. The second surface 32 of the function housing 3 has a plurality of holders 323. Each of the holders 323 is provided at a corresponding one of four corners of the second surface 32. Each holder 323 has a cylindrical shape protruding from the second surface 32. In each holder 323, a corresponding one of the elastic bodies 8 is fitted in, and thereby, the plurality of elastic bodies 8 are provided in the second surface 32. Each elastic body 8 has a tip end surface protruding slightly beyond a tip end surface of the heat dissipator 34. Thus, in a state where the function housing 3 is in the closed position, a state is achieved where the tip end surfaces of the elastic bodies 8 protrude toward the second surface 22 of the operation housing 2 beyond the tip end surface of the heat dissipator 34. Thus, the gap 7 is formed between the heat dissipator 34 and the operation housing 2 due to the elastic bodies 8 located between the heat dissipator 34 and the operation housing 2. That is, the gap 7 dimensioned such that the tip end surfaces of the elastic body 8 protrude beyond the tip end surface of the heat dissipator 34 is formed between the heat dissipator 34 and the second surface 22 of the operation housing 2.

[0033] In the function module 1 according to the present embodiment, the battery pack 4 is a battery pack for a power tool. That is, the battery pack 4 is, for example, a battery pack used in a power tool including a motor of an electric wrench, an electric screw driver, an electric drill, and the like. As the battery pack 4, for example, a housing body 42 in which a plurality of lithium ion batteries are connected to each other in series is used. The battery pack 4 has a rated voltage of, 14 V, 18 V, or the like.

[0034] In the function module 1 according to the present embodiment, the battery pack 4 is detachably attached with the battery pack 4 being exposed at the specific plane 24 of the operation housing 2. That is, the battery pack 4 is detachably attached to the specific plane 24 of the operation housing 2, and in a state where the battery pack 4 is attached to the specific plane 24, the battery pack 4 is not fully covered with the operation housing 2 and is thus partially exposed. The specific plane 24 is the first surface 21 of the operation housing 2. That is, the specific plane 24 is an opposite surface from the second surface 22 in a thickness direction of the operation housing 2. In the function module 1 according to the present embodiment, the function module 1 is carriable with the battery pack 4 being in a detached state and thus has excellent portability.

[0035] As illustrated in FIG. 7, the specific plane 24 has a recess 25 to which the battery pack 4 is to be attached. The recess 25 is provided with three hooks 251 each having an L-shape. The hooks 251 are engaged with respective hooks of the battery pack 4. The recess 25 is further provided with a communication connector 252 and two power supply terminals 253. The communication connector 252 is connectable to a communication connector of the battery pack 4. The two power supply terminals 253 are connected to connection terminals of the battery pack 4 by plug connection.

[0036] When the battery pack 4 is attached to the operation housing 2, part of the battery pack 4 is inserted into the recess 25 such that the hooks of the battery pack 4 do not interfere the hooks 251 of the recess 25. Then, the battery pack 4 is shifted in one direction, and thereby, the battery pack 4 is attachable to the recess 25. When the battery pack 4 is attached to the recess 25, the hooks of the battery pack 4 are engaged with the hooks 251 of the recess 25. Moreover, a lock section of the battery pack 4 locks the hooks 251 engaged with the hooks of the battery pack 4.

[0037] When the battery pack 4 is detached from the operation housing 2, for example, an unlock operation section 41 provided to the battery pack 4 is operated to shift the battery pack 4 in a direction opposite to the one direction, and then, the battery pack 4 is moved in a direction away from the recess 25.

[0038] In the function module 1 according to the present embodiment, the center of gravity G of the function housing 3, the operation housing 2, and the battery pack 4 is in the battery pack 4 in a state where the function housing 3 is in the open position. That is, when the function housing 3 and the operation housing 2 are located not to overlap each other in the thickness direction of the function housing 3, the center of gravity G of the function housing 3, the operation housing 2, and the battery pack 4 is in the battery pack 4. The center of gravity G is in the battery pack 4 also when the open position of the function housing 3 corresponds to the maximum angle between the second surface 32 of the function housing 3 and the second surface 22 of the operation housing 2. Thus, when the function module 1 according to the present embodiment is used in a state where the function module 1 is placed with the battery pack 4 facing down, the function module 1 can be used in a state where the function module 1 hardly tips over even if some force is applied to the function module 1.

[0039] Moreover, the center of gravity G of the function housing 3, the operation housing 2, and the battery pack 4 is in the battery pack 4 in a state where the function housing 3 is in the closed position. That is, also when the function housing 3 and the operation housing 2 are located to overlap each other in the thickness direction of the function housing 3, the center of gravity G of the function housing 3, the operation housing 2, and the battery pack 4 is in the battery pack 4. That is, in the function module 1 according to the present embodiment, the center of gravity G is in the battery pack 4 both in a state where the function housing 3 is in the open position and in a state where the function housing 3 is in the closed position.

[0040] The function module 1 according to the present embodiment further includes a power supply port 9 for supplying electric power to the battery pack 4. That is, the function module 1 according to the present embodiment is configured to supply electric power of the battery pack 4 via the power supply port 9 to another electric appliance. The power supply port 9 is, for example, USB connector. Electrically connecting a cable to the power supply port 9 enables electric power to be supplied to another electric appliance.

[0041] The power supply port 9 is provided in an end surface 26 on an opposite side from the first support 61 in the prescribed direction S of the operation housing 2. That is, the power supply port 9 is provided to the end surface 26 of the operation housing 2. The end surface 26 is not provided with the first support 61 to be connected to the second support 62 which supports the function housing 3. The power supply port 9 is provided to the end surface 26 which is not provided with the first support 61. Therefore, when a cable is attached to the power supply port 9 and when the cable is detached from the power supply port 9, attaching and detaching of the cable is less likely to be obstructed by the first support 61, and the attaching and the detaching of the cable is thus easily performed.

[0042] The power supply port 9 is recessed in the end surface 26 and is closed with a lid 91 when the power supply port 9 is not used. To use the power supply port 9, the lid 91 is opened to expose a connector in the power supply port 9, and a cable is connected to the connector.

[0043] As illustrated in FIGS. 9 and 10, the function module 1 of the present embodiment further includes the handle 5 via which the function housing 3 and the operation housing 2 are hung and held on, for example, a bar on a wall. That is, the function housing 3 and the operation housing 2 are hung and held by the handle 5. Thus, the function module 1 according to the present embodiment is usable not only in a state where the function module 1 is placed with the battery pack 4 facing down but also in a state where the handle 5 is hung on a wall or from a ceiling. The handle 5 is used not only by being hung but also by being held by hand. Holding the handle 5 by hand enables portability and transportability to be improved. Moreover, as illustrated in FIG. 9, the handle 5 is provided with a hook 55 for suspending the handle 5.

[0044] The handle 5 includes a plurality of (e.g., two) arms 51 and a hanging part 52 provided between ends of the arms 51 on one side, and the handle 5 has a frame shape with one side being open. At a tip end of each arm 51 (at an end on an opposite side from the hanging part 52), a connector 53 which is cylindrical is provided. Each connector 53 is rotatably coupled to a corresponding one of two third supports 63 provided to the operation housing 2.

[0045] The handle 5 is rotatably attached to the operation housing 2 via the third supports 63 at an opposite end of the operation housing 2 from the first support 61. That is, the handle 5 is attached to the third support 63 to be rotatable about a third rotation axis Z extending through the third supports 63. The first rotation axis X and the third rotation axis Z are parallel to each other. Moreover, the third supports 63 are provided at an opposite end of the operation housing 2 from the first support 61, that is, at an end provided with the end surface 26 to protrude beyond side surfaces of the operation housing 2 (side surfaces facing each other in a direction along the third rotation axis Z).

[0046] In a state where the function housing 3 is in the closed position, the handle 5 is rotatable on an opposite side from the battery pack 4. That is, also when the function housing 3 and the operation housing 2 are located to overlap each other in the thickness direction of the function housing 3, the handle 5 is rotatable on a side where the function housing 3 and the operation housing 2 are provided. That is, as illustrated in FIG. 1, when the handle 5 is rotated to move upward with the function housing 3 being in the closed position, the handle 5 rotates such that the hanging part 52 of the handle 5 passes through a side where the function housing 3 is provided (e.g., above the function housing 3). Then, in a state where the function housing 3 is in the closed position as shown in FIG. 8, the handle 5 protrudes in the prescribed direction S.

[0047] The function module 1 according to the present embodiment can change the state of the handle 5 from a state where the handle 5 protrudes in the prescribed direction S to a state where the handle 5 protrudes on an opposite side from the prescribed direction S and vice versa with the function housing 3 being in the closed position, that is, in a compact form. Thus, the function module 1 according to the present embodiment is convenient to use.

[0059] This aspect has the advantage that attachment and detachment of the battery pack (4) can be easily performed, and thus, the function module (1) with improved operability and portability can be provided.

[0060] In a function module (1) of a fourth aspect referring to any one of the first to third aspects, in a state where the function housing (3) is in the closed position, the operation housing (2) is within a projection plane (M) of the function housing (3) when viewed in plan.

[0061] This aspect has the advantage that the function module (1) which has improved portability and which is compact can be provided.

[0062] In a function module (1) of a fifth aspect referring to any one of the first to fourth aspects, the heat dissipator (34) includes an uneven shape (340) formed on the second surface (32).

[0063] This aspect has the advantage that the surface area of the e heat dissipator (34) can be increased by the uneven shape (340), and thus, the function module (1) with improved heat dissipation can be provided.

[0064] In a function module (1) of a sixth aspect referring to the fifth aspect, the uneven shape (340) includes a linear part extending in a direction orthogonal to the first rotation axis (X).

[0065] This aspect has the advantage that the heat dissipator (34) can dissipate heat in the direction orthogonal to the first rotation axis (X), and thus, the function module (1) with improved heat dissipation can be provided.

[0066] In a function module (1) of a seventh aspect referring to any one of the first to sixth aspects, in a state where the function housing (3) is in the closed position, a gap (7) is formed between the heat dissipator (34) and the operation housing (2).

[0067] This aspect has the advantage that heat dissipation via the gap (7) is possible, and thus, the function module (1) with increased heat dissipation can be provided.

[0068] A function module (1) of an eighth aspect referring to any one of the first to seventh aspects further includes an elastic body (8), the elastic body (8) being located between the heat dissipator (34) and the operation housing (2) in a state where the function housing (3) is in the closed position.

[0069] This aspect has the advantage that impact is more likely to be absorbed by the elastic body (8), and thus, the function module (1) with increased operability and portability can be provided.

[0070] A function module (1) of a ninth aspect referring to the third aspect further includes the operation section (23) located on an opposite surface of the operation housing (2) from the battery pack (4).

[0071] This aspect has the advantage that when the operation section (23) is operated, the battery pack (4) does not obstruct the handle (5), and thus, the function module (1) with improved operability can be provided.

[0072] In a function module (1) of a tenth aspect referring to the ninth aspect, the operation section (23) is provided in a recess (231) formed in the opposite surface of the operation housing (2) from the battery pack (4).
