Best Mode for Carrying Out the Invention
I. First Embodiment
1. Entire Structure and Operation
[0026] A moving toy 1 includes a base member 2 and moving bodies 3 as shown in FIGS. 1A, 1B and 1C. A field board 4 which forms a space for moving is provided to the base member 2. The moving bodies 3 are disposed on the field board 4. Further, a power supply switch 5 and a mode selector switch 6 are provided to the base member 2.
[0027] In the moving toy 1, when the power supply switch 5 is turned ON and mode selection is performed through the mode selector switch 6, the moving body (bodies) 3 moves in accordance with a pattern corresponding to the selected mode. For example, the moving body (bodies) 3 moves around on the field board 4 in accordance with a predetermined pattern.
2. Detail
(1) Base Member 2
[0029] As shown in FIG. 2, a plurality of control coils 7 are provided beneath the field board 4. The control coils 7 are disposed such that the magnetic flux thereof goes beyond the field board 4. In FIG. 3, there is shown a block diagram of a drive circuit to drive the control coils 7. A control device 21 is mounted into a drive circuit 20. The control device 21 controls the control coils 7 in accordance with control programs stored in a storage device 22. Although not particularly limited, the control includes control of on/off of conduction, control of the order of the conduction, control of the direction of the current flowing through the control coils 7, and control of the intensity of the current.
(2) Moving Body 3
[0030] As shown in FIG. 4, a ring-shaped magnet 10 is disposed in each of the moving bodies 3. Moreover, in each of the moving bodies 3, provided are a coil 11 placed in a center of the ring-shaped magnet 10, and light-emitting diodes 12 connected to the coil 11 in series. The light-emitting diodes 12 are, for example, mounted in each of the mobbing bodies 3 at the positions of the eyes thereof.
3. Operation and Movement
[0031] When the power supply switch 5 is turned ON and a mode is selected through the mode selector switch 6, a control program corresponding to the selected mode is read from the storage device 22 by the control device 21, and the control coils 7 are subjected to conduction control in order in accordance with the control program. More specifically, the conduction control is performed such that the moving body (bodies) 3 receives attraction force from the control coil(s) 7 disposed in the direction in which the moving body (bodies) 3 is moving, while the moving body (bodies) 3 receives repulsion force from the control coil(s) 7 disposed directly under the moving body (bodies) 3. The moving body (bodies) 3 thus moves toward the direction of the attraction force. Moreover, since induced electromotive force is generated at this time at the coil(s) 11, the light-emitting diodes 12 are turned on.
[0032] Here, it goes without saying that it is possible to stop the moving bodies 3 by cutting the conduction to the control coils 7. However, it is also possible to change, after the moving body (bodies) 3 is stopped, the intensity or direction of the current flowing through the control coils 7 and turn on the light-emitting diodes 12, with the moving body (bodies) 3 kept stopped.
4. Advantageous Effect
[0033] Since the moving bodies 3 are operated through control of the conduction to the control coils 7, it is possible to allow the moving bodies 3 to make complicated and unpredictable movement.
II. Modification of the Invention
[0034] Hereinabove, an embodiment of the present invention has been described. The present invention, however, is not limited to the above embodiment. It goes without saying that various modifications can be made without departing from spirit and scope of the invention.
[0035] For example, a figure of a car or a train may be used as the moving body 3. In this case, for example, a magnet may be provided to the vehicle body, and the wheels may be rotated by permitting attraction force or repulsive force to act on the vehicle body through control of the conduction to the control coils 7. Moreover, in this case, it is preferable to provide on the field board 2 a road, a production related to cars (for example, garage), a gas station, and the like. Further, light-emitting diodes may be mounted in the positions of the front lights of the car toy.
[0036] Moreover, a figure of a teeter-totter (production) may be used as the moving body 3. In this case, a magnet is mounted under at least one of the seats, and the teeter-totter is reciprocally moved by permitting attraction force or repulsive force to act on the magnet.
[0037] Further, as shown in FIG. 5, by attaching the coil 11 to the moving body 3, generating induced electromotive force to the coil 11 through control of the conduction to the control coils 7 performed by the control device 21, and generating new magnetic flux at the coil 11, part of the moving body 3, for example, ears 30, may be operated around an axis 31 through a magnet 32 due to the generated magnetic flux.
