[0009] Hereinafter, the embodiments will be described in detail with reference to the attached drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. Also, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted. Also, in each figure, the up, down, left, and right directions relative to the paper surface are used in the description in the text as the up, down, left, and right directions of the parts (or components) in this embodiment.

[0010] First, a circuit diagram of a light emitting circuit constituting a light emitting performance unit corresponding to this embodiment is shown in Fig. 1. The light emitting circuit can be constructed by arranging light emitting bodies such as LEDs of multiple colors on the wiring of a flexible printed circuit board (FPC). By arranging the light emitting body on the flexible printed circuit board at any part of a model or a doll toy (hereinafter collectively referred to as a model), it is possible to light up a specific part of the model.

[0011] The circuit diagram shown in Figure 1 is a simplified illustration of the light emitting circuit. Also, the number of light emitters is shown as a limited number for illustrative purposes only, but a larger number of light emitters can be arranged on the flexible printed circuit board.

[0012] In FIG. 1, the light-emitting circuit 10 is configured to include a power source 100, a current direction control circuit 110, a control unit 120, and a light-emitting unit 130. The power source 100 supplies power for the light-emitting circuit 10 to operate. The current direction control circuit 110 is a switching circuit that switches the direction of a current flowing through the light-emitting unit 130 between a first direction and a second direction opposite to the first direction, and operates in response to a control signal from the control unit 120. The control unit 120 supplies a control signal for controlling the operation of the current direction control circuit 110. The control unit 120 can be configured with a microcomputer, and switches the control signal supplied to the current direction control circuit 110 so that the direction of the current flow is switched between the first direction and the second direction at regular time intervals, for example.

[0013] The light emitting unit 130 is composed of two LEDs of different colors, and a first LED of a pair in which the first direction is the forward direction and a second LED of a pair in which the second direction is the forward direction are arranged in parallel. In other words, in the light emitting unit 130, the first LED and the second LED are connected in parallel with their polarities reversed. In addition, the first LED and the second LED have different light emission colors, and for example, if the first LED is red, the second LED can be green.

[0014] The color combination is not limited to the above, and any color combination can be used. Also, the colors to be combined may differ depending on the body part. For example, the arms and legs of the model may be a combination of red and green, and the torso and head may be a combination of red and blue. Also, some of the light-emitting body units 130 may be a combination of LEDs of the same color. In that case, the light emission color will not change in some body parts. For example, the light emission color may be maintained the same in the head of the model.

[0015] Furthermore, a plurality of light emitting units 130 are connected in series, so that one current direction control circuit 110 can control the light emission of the light emitting units 130 for the entire model.

[0016] The input section 140 is, for example, an operation input section such as a switch or button provided on the model, and the control section 120 may switch the light emission mode of the light emitter unit 130 according to the input from the input section 140 .

[0017] 2 is a diagram showing an example of the configuration of a flexible printed circuit board, which is a component of the light-emitting performance unit corresponding to this embodiment. A wiring 201 runs through the flexible printed circuit board 200, and the wiring 201 is covered with a base film and a coverlay. A light-emitting unit 130 is installed at an arbitrary position on the wiring 201. In the example shown in FIG. 2, the wiring 201 as a whole constitutes one wiring, and a current direction control circuit 110 is connected to a positive terminal 202 and a negative terminal 203, so that the direction of the current flowing through the wiring 201 is switched between a first direction and a second direction.

[0018] The light-emitting unit 130 is disposed on the front surface side of the flexible printed circuit board 200, and wiring 201 is connected to the LED of the light-emitting unit 130. For example, as shown in the area surrounded by the dotted line, the anode of the red LED and the cathode of the green LED are connected to the positive electrode side of the wiring 201, and the cathode of the red LED and the anode of the green LED are connected to the negative electrode side.

[0019] The flexible printed circuit board 200 is provided with engagement holes 204 for fixing to parts of a model, and the position of the flexible printed circuit board 200 can be fixed by connecting parts through the engagement holes 204. In addition, the flexible printed circuit board 200 can be bent as desired, so it can be attached by bending or flexing it to fit the shape of a part of a toy doll or a model.

[0020] 2, the flexible printed circuit board 200 is divided into limbs, shoulders and arms, and torso and waist, as shown by the dashed lines. The flexible printed circuit board 200 is connected to the torso and waist and the shoulders and arms, and is also connected to the torso and waist and the limbs (legs). As a result, the flexible printed circuit board 200 is disposed across the arms from the torso and waist via the shoulders, and also across the limbs from the torso and waist.

[0021] The flexible printed circuit board 200 is disposed to penetrate or pass through the inside of parts that constitute joints such as the neck, shoulders, elbows, waist, and knees. Therefore, it is desirable that the width of the flexible printed circuit board 200 is as narrow as possible, and it is necessary to reduce the number of wirings. In this embodiment, the number of wirings on the flexible printed circuit board 200 can be two, so that the flexible printed circuit board 200 can be configured with a minimum number of wirings. As an example, the width of the wiring part of the flexible printed circuit board is, for example, 4 mm at the narrowest point. However, the narrowest width of the wiring part differs depending on the size of the model or doll toy, and may be wider than 4 mm. Alternatively, it may be narrower than 4 mm. However, it is desirable to ensure that the width of each wiring is 1 mm and the width between each wiring is 0.3 to 0.5 mm in order to suppress noise.

[0022] Next, the light emission control of the light emitter unit 130 by the control unit 120 will be described with reference to Fig. 3. The control unit 120 can perform PWM (Pulse Width Modulation) control of the voltage supplied to the light emitter unit 130 through a current direction control circuit. Fig. 3 shows an example of control, with the vertical axis of the graph indicating the brightness of the LEDs as the ratio (unit: %) of the voltage pulse that is on per unit time in terms of the duty ratio. For both the red LED and the green LED, the duty ratio is increased from 0% to 90% in the first approximately 3 seconds, thereby increasing the brightness from the off state.

[0023] After that, when the duty ratio reaches 90%, it is dropped to 50% over about 3 seconds to reduce the brightness. After that, it repeats 50% to 90% four times in a cycle of about 6 seconds, and the brightness is increased and decreased accordingly. In the final 3 seconds at the end of the performance, it drops from 50% to 0%, gradually decreasing the brightness and turning off the lights. The red LED and green LED are lit alternately, and the above control is repeated. The interval between switching between the red LED and green LED can be about 10 seconds, for example, but it can be shorter or longer.

[0024] The above control method is merely an example, and the duty ratio and the lighting time can be controlled by other methods. Also, the red LED or the green LED may be switched to light up in response to an operation input from the input unit 140. Also, the input unit 140 may be provided with a plurality of buttons, and the light emitter unit 130 may be made to emit light with different duty ratios and lighting times in response to the type of button operated. Also, the switch of the input unit 140 may be arranged, for example, at a joint, and may be turned on by moving the joint. For example, the switch may be turned on when the arm arranged at the arm joint is posed to raise the arm.

[0025] Also, the model may be configured to be manually or automatically transformed from a first state to a second state, with the light-emitting body unit 130 hidden in the first state and the light-emitting body unit 130 exposed in the second state. In this case, in the first state, a part or the whole of the parts covering the light-emitting body unit 130 may be made of a light-shielding material. The light-shielding material may be configured, for example, by using molded parts with a color that absorbs light, or by attaching a reflective sticker.

[0026] In this embodiment, the flexible printed circuit board 200 is arranged inside the model, specifically across the torso and arms, and passing through joints (e.g., elbow joints and knee joints). This allows the light emitter units 130 arranged on the flexible printed circuit board 200 to be arranged at predetermined positions in the model. Specific examples of arrangements will be described below with reference to Figs. 4 to 6.

[0027] FIG. 4 shows an example in which the flexible printed circuit board is disposed on the torso and waist of the model. The flexible printed circuit board part 401 is disposed inside the clear part 402, and the light emitted from the LEDs at both ends passes through the clear part 402 and is irradiated to the outside. The clear part 402 is a member made of transparent ABS resin of a predetermined color and transmits light. The clear part 402 is covered from above with the part 403, which is made of polystyrene that does not transmit light. However, the use of materials other than polystyrene (thermoplastic resins such as polyethylene and ABS, thermosetting resins, metals, etc.) as materials for forming such light-opaque parts is not excluded. Therefore, the light emitted from the LEDs disposed on the part 401 is irradiated downward in the figure. The wiring part 404 of the flexible printed circuit board extends to other parts of the model through the opening of the part 405. In this way, the wiring of the flexible printed circuit board 200 passes through the parts of the model and is disposed inside the model (for example, the limbs).

[0028] The part 406 is a connector for connecting the flexible printed circuit board 200 to an external device or a power supply part. It can be used to connect to the current direction control circuit 110, the power supply 100, the control unit 120, the input unit 140, and the like shown in FIG. 1. In this embodiment, the current direction control circuit 110, the power supply 100, the control unit 120, and the input unit 140 are arranged as a battery box in a base on which the model is installed, and are connected to the connector by a predetermined wiring. However, this embodiment is merely an example, and all of the current direction control circuit 110, the power supply 100, the control unit 120, and the input unit 140 may be mounted inside the model, or at least some of them, for example, only the current direction control circuit 110, the current direction control circuit 110, the control unit 120, and the input unit 140 may be mounted, and the remaining parts may be placed in the base for installation.

[0029] Next, Figure 5 shows an example of the configuration of the legs of the model. Part 501 on which LEDs of a flexible printed circuit board are arranged is placed inside surface-emitting part 502. The surface-emitting part is made of GP (high impact PS) and has a milky white material. The above-mentioned clear part 402 was made of a see-through transparent color, but the surface-emitting part is intentionally made milky white like frosted glass, or semi-transparent to prevent light from escaping and diffuse the light so that the entire light-emitting surface shines uniformly.

[0030] A light-shielding part 503 that does not transmit light is disposed on the outside of the surface-emitting part 502, and is configured in combination with other parts so that the position of the light-shielding part 503 can be shifted so that the surface-emitting part 502 is partially exposed from a state in which the surface-emitting part 502 is concealed by the light-shielding part 503. The mechanism for shifting the position of the light-shielding part 503 is a general mechanism, so a description thereof will be omitted. This allows the light generated by lighting the LED to be confirmed through the gap in the light-shielding part 503 via the surface-emitting part 502.

[0031] Although the above describes a case where the surface-emitting part directly receives the light from the LED, the light may be diffused by the surface-emitting part via a clear part as shown in the exemplary cross-sectional view of Fig. 6. In Fig. 6, the light emitted from the LED 601 is transmitted to the surface-emitting part 605 via the clear parts 602 and 603 and diffused. Since the outside of the clear part is covered by the light-shielding part 604 that does not transmit light, the light is not diffused in the left-right direction but is transmitted in the direction of the part 605. By passing the light through the clear part in this way, the direction and range of light diffusion can be adjusted according to the size and thickness of the clear part and further by combining it with the light-shielding part.

[0032] As described above, according to this embodiment, it is possible to alternately or selectively emit light from a plurality of LEDs of different colors by controlling the direction of the current flowing through the wiring. In the illustrated embodiment, when the current flows in a first direction, the red LED emits light, and when the current flows in a second direction opposite to the first direction, the green LED emits light.

[0033] In this embodiment, the number of wirings can be minimized by connecting LEDs of different luminous colors in parallel in the opposite directions, which also minimizes the width of the flexible printed circuit board and allows LEDs to be placed at any position inside the model parts to create a lighting effect.

[0034] In addition, in this embodiment, by combining a light-emitting body (LED) that serves as the light source, a transparent part that transmits light, and a surface-emitting part that diffuses light, it is possible to transmit and diffuse light from the light source to any position on the model.

[0035] The invention is not limited to the above-described embodiment, and various modifications and variations are possible within the scope of the gist of the invention.
