BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[0001] The present invention relates to an audio signal reception type vocalizing toy which
is built into goods sold or supplied in a customer attraction facility such as a theme
park and receives an audio signal to generate voice, and a vocalizing toy apparatus
including a visible light transmitter which is used together with the audio signal
reception type vocalizing toy, is built into a mascot costume type image character
of a customer attraction facility, etc., and transmits the audio signal to the vocalizing
toy by visible light communication.
DESCRIPTION OF RELATED ART
[0002] Recently, theme parks have been opened in various places, and many people have enjoyed
facilities and attractions therein of the theme parks. In a theme park, a mascot costume
type image character, etc., appears at the site and puts on a performance, etc., for
many visitors for their enjoyment, with the aim of increasing park repeaters.
[0003] However, such a mascot costume type image character that only puts on performances
for visitors, is likely to lose the interest of the visitors, and does not always
contribute to the acquisition of repeaters.
[0004] Additionally, although the theme park sells various goods such as stuffed toys and
caps of various image characters so that the visitor has a sense of unity with and
enjoys the theme and image characters of the theme park, such conventional goods do
not always contribute to an increase in repeaters.
[0005] That is, since operation form and usage form of such goods of an image character
have no change in, for example, a home of a purchaser who returns from a theme park,
the goods only have an effect of making the purchaser a fan by inspiring him/her to
grow fond of an image character. This results in slightly giving a customer an incentive
to become a repeater of the theme park. Further, such conventional goods become common
as a sales period becomes longer, and new visitors are likely to lose interest in
the theme park.
[0006] On the other hand, regarding a stuffed toy, a voice generating toy has been conventionally
known, the toy being disclosed in Japanese Published Patent Application No.
2004-301942 A. However, in such a stuffed toy, voice is generated only by reproducing an audio
signal pre-stored in a memory of a voice generator built into the stuffed toy. Therefore,
if the stuffed toy is repeatedly used, users are also likely to lose interest. Accordingly,
new attractive goods are required to be developed so as to increase repeat visitors
of theme parks.
[0007] On the other hand, as an apparatus for transmitting voice guidance, a voice guidance
apparatus for transmitting an audio signal for voice guidance to a visually impaired
person approaching an automatic door has been conventionally known, the apparatus
being disclosed in Japanese Published Patent Application No.
2000-320238 A. When a door open/close control sensor of an automatic door detects an approaching
person, the voice guidance apparatus superimposes and transmits the audio signal for
voice guidance on an infrared ray or radio wave in the vicinity of the person from
a radio communication apparatus of infrared rays, radio waves, etc., and a visually
impaired person receives the audio signal superimposed on the infrared ray or radio
wave through a portable terminal or dedicated receiver. The portable terminal or dedicated
receiver receives the audio signal, demodulates the superimposed audio signal and
reproduces the audio signal, and then operates so as to generate the voice guidance
through a speaker, head phone, etc.
[0008] In the case where such a conventional voice guidance apparatus is set up in a customer
attraction facility such as a theme park, a receiver toy is created in a manner of
building a receiver in, for example, character goods, a visitor brings the receiver
toy to the customer attraction facility and simply listens to the voice guidance of
the audio signals transmitted by infrared rays or radio waves from the voice guidance
apparatus through the receiver toy as a user, the infrared rays or radio waves non-selectively
reach the receiver of the user and voice cannot be selectively made to reach each
visitor. Thus, personalization cannot be performed for the visitor as natural selection
of services and the visitor can hardly enjoy and obtain sufficient satisfaction, which
makes the aim of increasing repeaters of customer attraction facilities difficult.
SUMMARY OF THE INVENTION
[0009] It is an object of the present invention to provide an audio signal reception type
vocalizing toy and vocalizing toy apparatus capable of realizing personalization of
service for visitors of a customer attraction facility, allowing the visitors to sufficiently
enjoy and thus realizing an increase in repeaters.
[0010] The object of the present invention can be achieved by the audio signal reception
type vocalizing toy and vocalizing toy apparatus constituted as follows. That is,
the audio signal reception type vocalizing toy is an audio signal reception type vocalizing
toy which a user as a visitor wears and uses in the customer attraction facility,
the toy including: a light receiving unit which is arranged in the front of a wear
type toy body and has a light receiving element for receiving visible light through
a condensing lens; speaker(s) disposed in the wear type toy body; an amplifier for
amplifying a signal output from the light receiving unit; and a filter circuit for
integrating a digital audio signal output from the amplifier into an analog audio
signal and outputting it to the speaker(s). When the user, in the customer attraction
facility, directs the light receiving unit in the front of the wear type toy body
to a visible light source of a visible light transmitter for superimposing and projecting
an audio signal on visible light, the light receiving unit receives the visible light
and picks up the audio signal contained in a light reception signal, and sound containing
music, voice, etc. , is generated by the speaker. Moreover, a small voice generator
such as an earphone here belongs to the speaker.
[0011] Here, as the visible light, it is preferable to use blue light or white light containing
a blue light component. Additionally, in the case where the blue light or white light
containing the blue light component is used, it is preferable to use, as a light receiving
element of the light receiving unit, a photodiode for blue laser capable of receiving
the blue light at high sensitivity. Additionally, as the wear type toy body, the following
toys are applicable: a cap type toy which a user puts on his/her head; a glasses type
toy which is attached to a face; and a pendant type toy which is attached to a chest.
In the case where the cap type toy is used as the wear type toy body, the light receiving
unit including the condensing lens may be arranged at the approximate center of the
front of the cap type toy, and the speakers may be arranged in the vicinity of ears
at both sides of the cap type toy.
[0012] On the other hand, the vocalizing toy apparatus of the present invention includes:
the audio signal reception type vocalizing toy which a visitor wears in a customer
attraction facility; and a visible light transmitter which is attached to an image
character or installed object of the customer attraction facility and projects visible
light, on which an audio signal is superimposed, to the audio signal reception type
vocalizing toy. The audio signal reception type vocalizing toy includes: the light
receiving unit which is arranged in the front of the wear type toy body and has the
light receiving element for receiving visible light through the condensing lens; the
speaker(s) disposed in the wear type toy body; the amplifier for amplifying a signal
output from the light receiving unit; and the filter circuit for integrating a digital
audio signal output from the amplifier into an analog audio signal and outputting
it to the speaker(s). When the user, in the customer attraction facility, directs
the light receiving unit in the front of the wear type toy body to the visible light
source of the visible light transmitter for superimposing and projecting an audio
signal on visible light, the light receiving unit receives the visible light and picks
up the audio signal contained in the light reception signal and sound containing music,
voice, etc., is generated by the speaker. The visible light transmitter includes:
a sound source unit as a sound source for outputting an analog audio signal; a modulating
circuit into which the analog audio signal output from sound source unit is input
and which modulates the signal to generate an audio transmission signal; and a light
projecting unit which makes a light projecting element drive to superimpose the audio
transmission signal on visible light and projects the visible light from the light
projecting element through a condensing lens, and projects visible light condensed
and having directionality to the audio signal reception type vocalizing toy and transmits
the audio signal.
[0013] Here, as the visible light to be projected from the light projecting unit, blue light
or white light containing a blue light component is used. It is preferable that a
blue light emitting diode is used as the light projecting element. Additionally, the
visible light transmitter is built into a head, chest, etc., of the image character
performing in the customer attraction facility, and the light projecting unit is attached
to the front of the head of the image character so as to face forward, and projects
the visible light condensed and having the directionality in a direction that the
head or chest of the image character faces. Additionally, as the modulating circuit,
a PWMmodulation circuit is preferably used which subjects an analog audio signal to
PWM modulation to generate an audio transmission signal.
[0014] In the audio signal reception type vocalizing toy and vocalizing toy apparatus according
to the present invention, in the case where, for example, the cap type toy is used
as the wear type toy body of the audio signal reception type vocalizing toy, a user
puts the vocalizing toy on his/her head, the visible light transmitter is attached
to, for example, a head of a mascot costume type image character in the customer attraction
facility, and the visible light, on which the audio signal is superimposed, is condensed,
provided with directionality in a relatively narrow range, and projected, forward
from the image character, from the light projecting unit which is the visible light
source of the visible light transmitter, in the customer attraction facility such
as a theme park.
[0015] Since in this state, the projected visible light is, for example, blue light or white
light and the blue light or white light is projected as a conical luminous flux, the
visitor of the customer attraction facility can, by using the visible light as a mark,
easily visually confirm a sending source of service by the image character.
[0016] Additionally, when the blue light or white light containing the blue light component
is used as visible light to be projected on which an audio signal is superimposed,
the photodiode for blue laser having high sensitivity and high responsiveness can
be used for the light receiving element. Further, a blue light emitting diode operating
at high speed, or a white light emitting diode for emitting white light by irradiating
the blue light of the blue light emitting diode onto a yellow phosphor can be used
for the light projecting element. Thus, PWM modulation for performing modulation by
a high frequency signal of several hundred KHz to several MHz can be adopted for visible
light communication.
[0017] Accordingly, compared with the conventional case of using generally adopted FM modulation,
FSK modulation or the like when transmitting an audio signal by radio communication,
neither a complicated demodulating circuit nor a wave detecting circuit is necessary
for a receiver, and an electric circuit on the reception side can be extremely simplified
while the sound quality of voice output by the receiver is kept excellent. Thus, the
manufacturing cost of a visible light receiver, audio signal reception type vocalizing
toy, is remarkably reduced, and an extremely low-priced vocalizing toy can be provided
for users.
[0018] Additionally, since an average level of digital signals with the PWM modulation is
constantly fixed, the luminance of visible light, on which a signal is superimposed,
is approximately fixed and is unchanged regardless of volume and modulation frequency.
Therefore, a user seeing the visible light does not feel discomfort. Additionally,
in the case where the visible light transmitter and the audio signal reception type
vocalizing toy approach each other or move away from each other, little influence
is caused to the volume and sound quality if the level of the light reception signal
on the reception side is not less than a preset threshold. Furthermore, in the case
where the distance between the transmitter and toy further move away from each other
and the level of the light reception signal is less than the threshold, no voice is
only generated. This case is similar to the case where the power of the audio signal
reception type vocalizing toy is turned off, and causes no displeasure to the user.
[0019] In a state where a user wearing the vocalizing toy, during usage, approaches, for
example, a mascot costume type image character projecting blue or white visible light
and approximately faces the front of the mascot costume, the light receiving unit
of the vocalizing toy is directed to the light projecting unit of the visible light
transmitter, and the visible light, on which the audio signal is superimposed, is
projected from the light projecting unit of the visible light transmitter and received
by the light receiving unit of the audio signal reception type vocalizing toy.
[0020] At this time, the light receiving element of the light receiving unit subjects light
to photoelectric conversion and outputs a light reception signal, the signal is amplified,
and then integrated into an analog audio signal to be output to the speaker (s) by
the filter circuit. Thus, voice, for example, "I am ···. Good afternoon!," is generated
by the speaker, the user can, with a great sense of closeness, listen to the voice
just like a greeting from the image character.
[0021] Additionally, the user of the vocalizing toy recognizes the voice of the greeting
as not a common expression sent to the general public but as an expression of which
the content is extremely naturally selected and which is sent from the image character
only to him/her, and thus can obtain a great impression.
[0022] Particularly, in the case where in the customer attraction facility, a plurality
of image characters (for example, John and Mary) are juxtaposed and the visible light
having the directionality is projected to a user from each of the visible light transmitters
attached to mascot costumes of the image characters, the user wearing the vocalizing
toy, selectively, can listen to the voice of John, for example, "I am John. Good afternoon!,"
when facing John, or can selectively listen to the voice of Mary, for example, "I
am Mary. Good afternoon! , " when facing Mary.
[0023] Thus, the user, when facing John or Mary who are image characters, can feel that
the image characters are just talking to him/her, and thus natural service selection
and personalization can be effectively presented to the visitor.
[0024] In the case where the user thus wears the audio signal reception type vocalizing
toy and enters the customer attraction facility, the user can obtain a greater fresh
and enjoyable experience compared with the case of putting the audio signal reception
type vocalizing toy in his/her home, etc., and the experience can be obtained only
in the customer attraction facility. Since this greatly inspires users to visit the
customer attraction facility again, the aim of increasing repeaters can be realized
by using such an audio signal reception type vocalizing toy in the customer attraction
facility.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0026] Hereinafter, embodiments of the present invention will be described with reference
to the drawings. Moreover, the present invention is not limited to the embodiments.
Various modifications in the components of the appended claims or equivalents to the
components are within the scope of the appended claims.
[0027] FIG. 1 is a front view of a cap type toy 1 as an audio signal reception type vocalizing
toy, FIG. 2 is a block diagram of an electric circuit of a visible light receiver
5 built into the toy 1, and FIG. 3 is a block diagram of a visible light transmitter
2.
[0028] A wear type toy body 10 is formed in a cap shape in the cap type toy 1 as an audio
signal reception type vocalizing toy as shown in FIG. 1, and a user puts and uses
the body on his/her head. Additionally, the wear type toy body 10 is formed in the
cap shape by modeling the outer appearance of an image character in a customer attraction
facility such as a theme park. A light receiving unit 11 is attached to the approximate
center of the front of the body 10 so as to face forward. In the light receiving unit
11, a light receiving element 13 is provided which receives and subjects visible light
to photoelectric conversion to output a light reception signal, a condensing lens
12 is arranged in the front of the light receiving element 13, and visible light incident
from the front is condensed so as to be projected to the light receiving element 13.
[0029] As the light receiving element 13, for example, a photodiode for blue laser is used
which receives blue visible light at high sensitivity, subjects the received light
to photoelectric conversion at high conversion efficiency, has high responsiveness
and outputs the light reception signal.
[0030] A light receiving element such as a photo transistor, which has been conventionally
used, for receiving red or yellow visible light or infrared rays has sensitivity and
response speed lower than those of the light receiving element 13 for which the photodiode
for blue laser is used. The conventional light receiving element can neither receive
visible light, on which PWM modulation has already been performed at a high frequency
of several hundred kHz to several MHz, nor pick up an audio signal having high fidelity
and excellent sound quality, although the light receiving element 13, for which the
photodiode for blue laser is used, of the present invention can perform them.
[0031] In the light receiving unit 11, a head amplifier 14 is connected to the light receiving
element 13 and the light reception signal output from the light receiving element
13 is first amplified and output by the head amplifier 14. An analog amplifier 15
is connected to an output side of the head amplifier 14 as shown in FIG. 2 so that
an input signal is amplified in an analog manner as it is. An output side of the analog
amplifier 15 is connected to a waveform shaping circuit 16 in which a comparator is
used, and the waveform shaping circuit 16 removes a DC component from the light reception
signal to shape the waveform of the signal.
[0032] Since the light reception signal is amplified by the analog amplifier 15 although
basically being an AC rectangular signal with the PWM modulation, the DC component
is superimposed on the signal. The light reception signal is made to pass through
the waveform shaping circuit 16, and thus the DC component is removed and the light
reception signal is output as a rectangular wave signal having a shaped waveform.
A digital amplifier 17 is connected to an output side of the waveform shaping circuit
16, and the rectangular wave signal output from the waveform shaping circuit 16 is
transmitted to the digital amplifier 17 to be amplified as a digital signal.
[0033] As shown in FIG. 2, a filter circuit 18 is connected to an output side of the digital
amplifier 17. The filter circuit 18 is constituted by a low-pass filter including
a coil L and a capacitor C, and returns and outputs the received signal into an analog
audio signal before being subjected to the PWM modulation in a manner of changing
the AC rectangular wave signal with the PWM nodulation into a smooth analog signal.
An output side of the filter circuit 18 is connected to speakers 19, and the audio
signal received by the visible light receiver 5 of the cap type toy 1 is generated
into voice at the ears of the user by driving the speakers 19.
[0034] As described above, when the blue light is used as visible light to be projected,
on which an audio signal is superimposed, a blue light emitting diode capable of performing
switching operation at high speed can be used for a light projecting element 23 described
later of the visible light transmitter 2 in the case where the photodiode for blue
laser having high sensitivity and high speed responsiveness is used for the light
receiving element 13. Thus , the PWM modulation for performing modulation by a high
frequency signal of several hundred KHz to several MHz can be adopted.
[0035] Therefore, compared with the conventional case of using generally adopted FM modulation,
FSK modulation or the like in transmitting an audio signal by radio communication,
neither a complicated demodulating circuit nor a wave detecting circuit is necessary
for a receiver, and an electric circuit on the reception side can be extremely simplified
while the sound quality of voice output by the receiver is kept excellent. Accordingly,
the manufacturing cost of the visible light receiver 5, the cap type toy 1, is remarkably
reduced, and an extremely low-priced vocalizing toy can be provided for the user in
the customer attraction facility.
[0036] As shown in FIGS. 4, 5, the visible light transmitter 2 is attached to a mascot costume
type image character 20 in the customer attraction facility, and projects the visible
light, on which the audio signal is superimposed, to the cap type toy 1. The visible
light transmitter 2 can be attached to not only such a mascot costume but also various
installed objects and exhibits in the customer attraction facility.
[0037] An electric circuit of the visible light transmitter 2 includes, as shown in FIG.
3: a sound source unit 27 as a sound source for outputting an analog audio signal;
a PWM modulation circuit 25 into which the analog audio signal output from the sound
source unit 27 is input and which subjects the analog audio signal to the PWM modulation
to generate an audio transmission signal; and a light projecting unit 21 which makes
a light projecting element 23 drive to superimpose the audio transmission signal on
visible light and projects the visible light from the light projecting element 23
through a condensing lens 22, and projects visible light condensed and having directionality
to the cap type toy 1 and transmits the audio signal.
[0038] The sound source unit 27 is a unit as a sound source for outputting an audio signal.
As the sound source unit 27, the following units can be used, for example: an audio
reproducing unit for reading and reproducing a digital audio signal stored in an MD,
CD, semiconductor memory, hard disk or the like as a recording media and outputting
the signal as an analog audio signal; a unit for converting and outputting an audio
signal transmitted through a network into an analog audio signal; and a unit for converting
and outputting voice of a person in a mascot costume type image character into an
audio signal through a microphone. As shown in FIG. 3, an output side of the sound
source unit 27 is connected to an input side of the PWMmodulation circuit 25, and
a triangular wave oscillation circuit 26 is further connected to a triangular wave
input side of the PWM modulation circuit 25.
[0039] The triangular wave oscillation circuit 26 is a circuit for oscillating and outputting,
for example, a triangular wave signal having a high frequency of approximately 800KHz,
and the PWM modulation circuit 25 takes the triangular wave signal in from the triangular
wave oscillation circuit 26 and takes the analog audio signal in from the sound source
unit 27. Both the signals are input into a reverse input side and a non-reverse input
side of a comparator respectively, a PWM signal for switching in accordance with a
magnitude relationship between the signals is output from the comparator, and the
PWMmodulation is performed.
[0040] A pulse-shaped PWM rectangular signal having, by such PWM modulation, a pulse width
in accordance with the level of the analog audio signal is output from the PWMmodulation
circuit 25 to a light projection driving circuit 24, the rectangular signal being
shown in FIG. 6. The light projection driving circuit 24 of the light projecting unit
21 is connected to an output side of the PWM modulation circuit 25 as shown in FIG.
3, the light projecting unit 21 light projection-drives the light projecting element
23 by the light projection driving circuit 24, and blue light or visible light containing
a blue light component, which is especially easily recognized, is projected from the
light projecting element 23. The light projecting unit 21 is attached to, for example,
the front of a head of the mascot costume type image character 20 in the customer
attraction facility so as to face forward as shown in FIGS. 4, 5, condenses the blue
visible light through the condensing lens 22, and provides and projects the light
with the directionality forward.
[0041] Generally, the mascot costume type image character 20 is moved by a person wearing
it and various performances are performed for visitors by the person. However, a robot
other than a person can be made to wear and move the mascot costume, or the visible
light transmitter 2 can be attached to not the mascot costume but an object which
is installed in the customer attraction facility and formed by modeling the image
character.
[0042] Next, operation of the audio signal reception type vocalizing toy and vocalizing
toy apparatus constituted as the above will be described. The cap type toy 1 as the
audio signal reception type vocalizing toy is formed by modeling the head of the image
character 20 in the customer attraction facility such as a theme park as described
above, sold in the customer attraction facility, etc., and the user purchases it.
[0043] The user (visitor) puts the cap type toy 1 on his/her head, and enjoys the performance
of image character 20, etc. , in the customer attraction facility. Since, as described
above, the visible light transmitter 2 is attached to the head of the mascot costume
type image character 20 and the light projecting unit 21 is arranged in the front
of the head of the mascot costume so as to face forward, the blue visible light, on
which the audio signal is superimposed, is condensed, provided with directionality
in a narrow range and projected forward from the light projecting unit 21 in a direction
that the head of the mascot costume type image character 20 faces.
[0044] Since the blue visible light is projected as a conical luminous flux in this state,
the visitor, user, can easily visually confirm a sending source of service of the
image character 20 by using the blue visible light as a mark.
[0045] When the user wearing the cap type toy 1 approaches the mascot costume type image
character 20 projecting the blue visible light and approximately faces the front of
the mascot costume, the light receiving unit 11 of the cap type toy 1 directs the
light receiving unit of the vocalizing toy to the light projecting unit 21 of the
visible light transmitter 2 and receives the visible light, which is projected from
the light projecting unit 21 of the visible light transmitter 2 and on which the audio
signal is superimposed, as shown in FIG. 4.
[0046] The light receiving unit 11 outputs the light reception signal, the output signal
is amplified, and then it is integrated into the analog signal and output to the speakers
19 by the filter circuit 18. Voice, for example, "I am ···. Good afternoon!," is generated
by the speaker 19. Thus, the user can listen to the voice just like a greeting from
the image character 20 only to him/her.
[0047] Thus, the user of the vocalizing toy recognizes the voice of the greeting as not
a common expression to many people but as an expression of which the content is extremely
naturally selected and which is sent from the image character 20 only to him/her,
and thus can obtain a great impression.
[0048] Additionally, in the case where as shown in FIGS. 4, 5, the plurality of image characters
20 (for example, John and Mary) are juxtaposed and the blue light or visible light
having the blue light component, which is condensed and provided with the directionality,
is projected to the user from each of the visible light transmitters 2 attached to
the mascot costume type image characters 20, the user wearing the cap type toy 1 can
listen to the voice of John, for example, "I am John. Good afternoon!," when facing
John, or selectively listen to the voice of Mary, for example, "I am Mary. Good afternoon!
, " when facing Mary.
[0049] Thus, the user can feel, when facing John or Mary of the image character 20, that
the image character just talks to him/her, and natural service selection and effect
personalization can be presented to the visitor.
[0050] In the case where the user thus wears the cap type toy 1 and enters the customer
attraction facility, the user can have an even fresher and enjoyable experience that
can be obtained only in the facility, compared with the case of putting the cap type
toy in his/her home. Therefore, a strong motivation to visit the customer attraction
facility again is created for the user. Such provision of the cap type toy 1 for the
visitors in the customer attraction facility securely allows an increase in repeaters
to be realized.
[0051] Moreover, although the blue light is used as the visible light in the above embodiment,
the same effect can be obtained even if a single color light such as a purple light
or a green light is used which has a wavelength approximating that of the blue light.
Additionally, visible light (white light) containing the blue light can be projected
by using a white light emitting diode which irradiates the blue light of the blue
light emitting diode onto a yellow phosphor so the yellow light is emitted, and combines
the yellow light with the blue light to generate white light. Since such white light
contains a large quantity of blue light components, the photodiode for blue laser
having high sensitivity and high speed responsiveness can be used as the light receiving
element.
[0052] Additionally, although the cap type toy 1 is used as the audio signal reception type
vocalizing toy in the above embodiment, a glasses type toy 30 to be attached to a
face or a pendant type toy 40 to be attached to a chest may be used, the toys 30,
40 being shown in FIGS. 7, 8. In the case of using the glasses type toy 30, a light
receiving unit 31 including a condensing lens and the head amplifier 14 described
above are arranged at the approximate center of the front of the glasses type toy
30, and a speaker 32, the analog amplifier 15 described above, waveform shaping circuit
16, digital amplifier 17 and filter circuit 18 may be arranged inside of the vicinity
of the ears at both sides of the glasses type toy 30. In the case of using the pendant
type toy 40, a light receiving unit 41 including a condensing lens is arranged in
the front of the pendant type toy 40, and a speaker 42, the head amplifier 14 described
above, analog amplifier 15, waveform shaping circuit 16, digital amplifier 17 and
filter circuit 18 may be arranged in the pendant type toy 40.
[0053] Further, although the visible light transmitter 2 is built into the head of the mascot
costume type image character 20 in the above embodiment, it may be, as shown in FIG.
9, built into a body of a stuffed toy type image character 50 so that the light projecting
unit 21 is attached to the front of the image character 50 so as to face forward.
In this case, the image character 50 is provided for the visitors in the customer
attraction facility, etc., and the visitor takes the stuffed toy of image character
50 together with the cap type toy 1, etc., home and can enjoy them at the home.
