  Preferred embodiments of the present invention are shown below. As shown in FIG. 2, the movable decorative device according to the present embodiment includes a front cover 5, a back cover 22, a rotating body 7 attached to the front cover 5, and a light emitting body 6 installed on the rotating body. The rotating body 7 is rotated by the driving force of the motor as shown in FIG. 7 and at the same time, the light emitting body 6 includes a plurality of LEDs, and emits light to enhance interest by power feeding from the electronic circuit board.

  As shown in FIGS. 1 and 9, the motor 1, the idle gear train 3 that meshes with the motor gear 2 of the motor 1, and the rotating body gear 4 that meshes with the idle gear train 3 are attached to the back surface of the front cover 5. It has been. In the present embodiment, a rotating body 7 including a light emitting body 6 is fixed to the rotating body gear 4. In the present embodiment, the motor 1 is attached to the end of the back surface of the front cover 5, and the driving force of the motor 1 is transmitted to the rotating body 7 via the motor gear 2 and the idle gear train 3. However, the present invention is not limited to this, as long as the driving force of the motor 1 can be transmitted to the rotating body 7.

  As a rotational speed regulating means of the rotating body 7, a Geneva mechanism in which one protrusion 8 formed on the rotating body gear 4 and a plurality of recessed portions 10 formed on the Geneva driven wheel 9 are sequentially meshed with each rotation of the rotating gear 4. Further, a convex portion 11 is formed on the Geneva driven wheel 9, and two stoppers 12 with which the convex portion 11 abuts are formed on the back surface of the front cover 5, so that the rotational speed of the rotating body 7 is increased. Was regulated. Therefore, when the rotating body 7 is rotated by driving the motor 1, the protrusion 8 formed on the rotating body gear 4 is 10 a of the recess 10 formed on the Geneva driven wheel 9 every time the rotating body gear 4 rotates once. 10b, 10c, 10d, and 10e in this order. At this time, since the rotation angle of the convex portion 11 formed on the Geneva driven wheel 9 is restricted to the angle range from the stopper 12a to the stopper 12b, the number of rotations of the rotating body 7 can be restricted. In the present embodiment, since the recesses 10 are formed at five locations, the rotating body 7 can rotate four times in the forward direction, and then rotate the motor 1 in the reverse direction to rotate the rotating body 7 in the reverse direction four times. be able to. In addition, the rotation speed of the rotary body 7 is not limited to this.

  As shown in FIG. 4, power is supplied to the light emitter 6 installed on the rotary body 7 to the rotary body side connector 14 as a power supply destination provided on the rotary body shaft 13 formed on the rotary body 7 and the electronic circuit board 15. This is performed by connecting the board-side connector 16 serving as a power supply source with a flexible flat cable 17. The flexible flat cable 17 is a thin electric wire having a flat structure. In the present embodiment, the flexible flat cable 17 is wound around and attached to the outer periphery of the rotating body shaft 13 in a spiral shape. Thereby, while the rotating body 7 rotates forward and backward four times, only the change that the winding of the flexible flat cable 17 around the rotating body shaft 13 becomes loose or strong occurs, and power supply to the light emitting body 6 is continued during this time. Can be done. In the present embodiment, since the flexible flat cable 17 is wound around the rotating body shaft 13 in the clockwise direction, the winding of the flexible flat cable 17 becomes strong while the rotating body shaft 13 rotates four times in the counterclockwise direction. Further, when the rotating body shaft 13 returns four turns clockwise, the winding of the flexible flat cable 17 becomes loose. Therefore, the flexible flat cable 17 is wound around the rotary shaft 13 after the rotational speed of the rotating body 7 is regulated by the rotational speed regulating means, so that the light emitter 6 can be supplied with power, and the flexible flat cable 17 can be pulled. Excellent durability due to low stress.

  The number of windings of the flexible flat cable 17 is preferably equal to or greater than the number of rotations of the rotating body 7.

  As shown in FIG. 4, the flexible flat cable case 18 is fixed to the back surface of the front cover 5 in order to accommodate the flexible flat cable 17. Further, it is preferable that a slit 19 is formed in the flexible flat cable case 18 and the end of the flexible flat cable 17 is led out to the outside through the slit 19.

  Furthermore, it is preferable to include a flexible flat cable presser 20 that presses the end of the flexible flat cable 17 led out of the flexible flat cable case 18 by rotating the end of the flexible flat cable 17 toward the electronic circuit board 15 by approximately 90 °. The cable 17 is preferably connected to the board-side connector 16 via the flexible flat cable retainer 20 and the flexible flat cable case 18.

  As shown in FIG. 1, a shield 21 is formed on the Geneva driven wheel 9, and this shield 21 is detected by a sensor (not shown) provided on the electronic circuit board 15 to detect the origin position of the rotating body 7. It can also be set as a structure. Thereby, even when the rotation speed of the rotating body 7 cannot be accurately controlled due to the step-out of the motor 1, the rotation of the rotating body 7 can be controlled by detecting the shielding portion 21 by the sensor.

  As described above, when the rotating body 7 is rotated, the number of rotations thereof is restricted. Therefore, only the change in which the winding of the flexible flat cable 17 attached to the rotating body shaft 13 in a spiral shape is loosened or strengthened. Therefore, since the power supply to the light emitter 6 can be maintained and the tensile stress on the flexible flat cable 17 is small, the durability is excellent. Furthermore, since it is cheaper than when a slip ring is employed, the manufacturing cost can be reduced.
