As shown in this figure, the moving mechanism section 4 is provided with a control board 42 and a battery box 43 in addition to a gear mechanism 41 for moving the light guide plate 31, and these are fixed to the upper end of the gripping section 2. It is attached to the fixed plate 40. In addition to being connected to the battery 431 in the battery box 43, the control board 42 is connected to the light emitting diodes 34 and 35 through the shaft member 21, and is configured to control the light emission of the light emitting diodes 34 and 35.
The gear mechanism 41 includes a rack member 411, a pinion member 412, a gear member 413, and a spring box 414. The rack member 411 is fixed to the shaft member 21 inserted through the grip portion 2, and rack teeth are formed along the X direction. The pinion member 412 has a small-diameter gear 412 a and a large-diameter gear 412 b that are formed coaxially. Among these, the small-diameter gear 412 a meshes with the rack teeth of the rack member 411, and the large-diameter gear 412 b Engage with teeth. Here, the shaft member 21 to which the rack member 411 is fixed is inserted through the entire length of the grip portion 2 so as to be movable along the X direction. As described above, the light guide portion 3 is guided to the lower end. A light plate 31 is attached. Further, the movement of the shaft member 21 in the X direction is restricted to a range in which the rack teeth of the rack member 411 that moves together with the shaft member 21 are not disengaged from the small-diameter gear 412 a of the pinion member 412.
The mainspring box 414 has a so-called pull-back mainspring structure, and has a gear member and a mainspring spring (not shown). Of these, the gear member is engaged with the shaft portion 413a of the gear member 413, and the gear member is rotated in accordance with the rotation of the gear member 413 (the rotation in the clockwise direction in FIG. 3). Is wound. When the mainspring spring is wound and urged and then loosened by the urging force, the gear member 413 is reversely rotated (rotated counterclockwise in FIG. 3) via the gear member, A mechanical sound that rotates the gear member is generated. Since the mainspring box 414 has a conventionally known pull-back mainspring structure, a detailed description thereof will be omitted. The pull-back spring is disclosed in, for example, Registered Utility Model No. 3023614.

  In the light emitting toy 1 having the above configuration, when the upper end of the shaft member 21 is pushed downward by the player, the light guide plate 31 fixed to the lower end of the shaft member 21 is moved downward, and at the same time, the rack member 411. The pinion member 412 and the gear member 413 are rotated by this movement, and the mainspring spring in the mainspring box 414 is wound. When the player releases his hand from the shaft member 21, the rack member 411 is moved upward together with the shaft member 21 through the pinion member 412 and the gear member 413 by the urging force of the mainspring spring. Also move upward. That is, when the player pushes the shaft member 21 downward, the light guide plate 31 reciprocates in the vertical direction (X direction).

  At this time, as the light guide plate 31 reciprocates in the X direction, the light emitting diodes 34 and 35 are controlled by the control board 42 to emit light. As a light emission mode at this time, first, the light emitting diode 35 emits a faint white light, and the light emission is gradually increased. Then, instead of the light-emitting diode 35, the light-emitting diode 34 starts to emit RGB colors, and after gradually flashing the RGB colors alternately, the light emission is gradually weakened. Then, instead of the light emitting diode 34, the light emitting diode 35 emits white light, and after this is gradually weakened, the light emission is stopped. Further, the light guide plate 31 is configured to move upward by the urging force of the spring when the light-emitting diode 34 blinks each color of RGB violently. At this time, the gear member in the spring box 414 rotates. A mechanical sound is emitted.

  The light of the light emitting diodes 34 and 35 irradiated into the light guide plate 31 in such a light emitting manner is irregularly reflected by the concave portion 31a to cause the concave portion 31a, that is, the decorative portion 5 to emit light. As a result, the sparkler firework pattern formed on the decorative portion 5 is brightly illuminated as if the sparkler fired gradually and ignited, leaving it with a remnant. In addition, when the light guide plate 31 and the lenticular lenses 32 and 33 move relative to each other in the X direction along the surfaces of the light guide plate 31 and the lenticular lenses 32 and 33, the picture pattern of the decorative portion 5 that is viewed through the lenticular lenses 32 and 33 changes. Furthermore, the mechanical sound of the gear member in the mainspring box 414 is emitted as if it is a sparking sound of a sparkler that scatters a spark violently.

  According to the light-emitting toy 1 described above, the picture pattern of the decorative portion 5 to which the light from the light-emitting diodes 34 and 35 is irregularly reflected is viewed through the lenticular lenses 32 and 33. Therefore, the player can enjoy the change of the picture pattern according to the viewing angle through the lenticular lenses 32 and 33, and can enjoy the brightly decorated picture pattern.

In addition, the player can enjoy a picture pattern that changes due to relative movement between the light guide plate 31 and the lenticular lenses 32 and 33.
Further, by providing the gear mechanism 41 for moving the light guide plate 31, the player does not have to manually move the light guide plate 31 and the lenticular lenses 32 and 33 directly, and the light guide plate 31 and the lenticular lens 32, It is possible to enjoy a picture pattern that changes due to relative movement with 33.
In addition, since the gear mechanism 41 is a mainspring mechanism that uses the biasing force of the mainspring spring, the light guide plate 31 can be moved with a simple configuration.

In addition, a picture pattern simulating a sparkler is formed on the decoration 5, and when the mainspring box 414 moves the light guide plate 31, it emits a mechanical sound simulating a sparkler igniting sound. You can enjoy a pseudo-firing sound with a light-decorated sparkler pattern, and you can enjoy the realism as if you were playing with real fireworks.
Furthermore, the presence of the stick-shaped grip 2 and the shape imitating hand-held fireworks can amplify the player's presence as if playing with real sparklers.
