In the operation of the music box device, the winding key 16 of the music box is rotated to wind up the entire dance. When the whole dance is gradually unwound by the speed control unit 13, the rotary drum 12 is rotated and the valve 5a of the diaphragm 5 is flipped by the engaging pin 15 to make the music sound. When the rotary drum 12 and the crank shaft 3 rotate, the crank portion 3b makes a circular motion when rotated clockwise in FIG.

In FIG. 4, the position of the crank portion 3b is shown in FIGS.
Then, it is position a. When the crank portion 3b is rotated by an angle of 45 ° as indicated by the solid line in FIGS. 9 and 11, it is in the b position in FIGS. At this time, the connecting member 8 is rotated to the upper position in FIG. 1 and to the right in FIG. 11, so that the slide shaft 7 is moved down and rocked to the right in FIG. When the crank portion 3b is further rotated by 45 ° as shown by the solid lines in FIGS.
Therefore, in FIG. 3, the position is c. At this time, the connecting member 8 is at the center position in FIG. 1 and is rotated to the lower position in FIG. 4 in FIG. 12, so that the slide shaft 7 is lowered and is swung leftward in FIG.

As shown by the two-dot chain line in FIGS. 10 and 12, the crank portion
When 3b is further rotated by 45 °, d in FIGS.
The position. At this time, the connecting member 8 is at the lower position in FIG.
In this case, since the slide shaft 7 is rotated leftward, the slide shaft 7 is moved up and rocked leftward in FIG. When the crank portion 3b is further rotated by 45 ° from the two-dot chain line in FIGS. 10 and 12,

When the above-described music box device is constructed, the slide shaft 7 and the connecting member 8 move up and down while the other side crank portion 3b of the crank shaft 3 makes one revolution from the position a and returns to the position a. It is possible to easily obtain a mechanism in which the slide motion is performed and the rocking motion is performed left and right. Further, since it is incorporated into the frame 1 of the driving source of the music box to form a unit, it can be easily attached by simply forming a through hole through which the slide shaft 7 is penetrated in various boxes, so that it can be easily incorporated. And the versatility is improved.

[0014]

When the present invention is constructed as described above, the slide shaft and the connecting member are slid up and down and left and right while the crank portion of the crank shaft makes one revolution and returns to the original position. It is easy to obtain a mechanism that is oscillated.
In addition, since it is incorporated into the frame of the driving source of the music box to make it into a unit, it can be easily mounted by simply forming a through hole through which the slide shaft penetrates in various boxes, so it can be easily assembled. Thus, it is possible to provide an orgol device having excellent effects such as improved versatility.
