- the first link 66b swings when the slide switch 66a is moved in the direction of the arrow (left side) shown in FIG.
- the second link 66c moves to the right by rotating counterclockwise about the shaft 65a.
- the second switching gear 66f meshes with the second drive gear 52c4
- the first switching gear 66e meshes with the idler 66g as shown in FIG.
- the rotational force of the handle 52c1 is transmitted to the upper rotating disk 55 via the idler 66g, and the upper rotating disk 55 rotates.
- the lower rotating disk 56 also rotates through the synchronization gear 57, so that the seat 64 connected thereto also rotates.
- the arm 65b connected to the swing shaft 65a also rotates counterclockwise, so that the shaft gear 65d is engaged with the third drive gear 52c5. Therefore, the rotational force of the handle 52c1 is transmitted to the drive shaft 65c via the shaft gear 65d, and the drive roller 65e also rotates as shown in FIG. 12 (d). Accordingly, the sheet 64 sandwiched between the spacer 52d and the driving roller 65e is sent out by both the spacer 52d and the driving roller 65e, and thus the sheet 64 can be stably rotated. Further, as shown in FIGS.
- the drive shaft 65c is provided with a plurality of press rollers 65f, and the sheet 64 has a whole area in the radial direction by the drive rollers 65e and the press rollers 65f. It moves toward the spacer 52d. That is, since the seat 64 is also brought close to the star wheel 52a adjacent to the spacer 52d, the claw portion provided on the star wheel 52a can be reliably meshed with the performance engaging portion provided on the seat 64. You can perform as expected. Since the sheet 64 is circular in plan view, the speed is different between the inside and outside in the radial direction.
- the speed on the circumference of the pitch circle of the idler 66g is equal to the speed on the circumference of the drive roller 65e (the length in the radial direction from the center axis of the upper rotating disk 55 to the idler 66g). / (Radial length from the central axis of the upper rotating disk 55 to the driving roller 65e). That is, since the rotational speeds of the upper rotating disk 55 and the lower rotating disk 56 and the seat 64 coincide with each other, they can be rotated in synchronization.
- the slide switch 66a is moved in the direction of the arrow (right side) shown in FIG. Accordingly, the first link 66b rotates clockwise around the swing shaft 65a, and the second link 66c moves to the left side. At this time, the second switching gear 66f is separated from the second drive gear 52c4, and the first switching gear 66e is also separated from the idler 66g as shown in FIG. 14 (b). Further, in this state, as shown in FIG. 14C, the arm 65b connected to the swing shaft 65a also rotates clockwise, so that the shaft gear 65d is also separated from the third drive gear 52c5, and the drive roller 65e is also shown in FIG. As shown in FIG.
- the vehicle is separated from the star wheel 52a.
- the rotational force of the handle 52c1 is not transmitted to the upper rotary plate 55, the lower rotary plate 56, and the seat 64.
- the shaft gear 65g connected to the swinging shaft 65a rotates clockwise
- the third switching gear 66j rotates counterclockwise.
- the fourth switching gear 66k also rotates counterclockwise.
- the knob 59 is moved downward via the knob shaft portion 59 c, and a driving engagement portion (not shown) provided on the knob 59 is connected to a driving mechanism (not shown) provided on the upper rotating plate 55. Since the engaging portion is engaged, the sheet 64 can be fast-forwarded or rewound at a high speed as the knob 59 rotates.
- the music box apparatus of the present invention is not limited to the above-described embodiments, and includes various modifications.
- each component member is shown in a simplified manner, but is not limited to this shape.
- the handle 2c1 that is manually rotated is provided as a drive unit that rotates the seat 14, but may be rotated by a motor.
- the music box apparatus according to the present invention can be played for a long time and can be reduced in thickness, so that it is suitable not only for use alone but also in combination with other music boxes.
