欠で生産性に劣り、個々の爪車と振動弁との位置
合わせ支持手段が面倒で組立性が悪い等の欠点が
ある。 Conventionally, disc-type music boxes and card-type music boxes are already known. However, for example, as shown in FIGS. 3 and 7 of US Pat. No. 523,567, the ratchet wheel 17 is rotatably fitted onto a shaft 22, and the shaft 22 is fixed to both ends of the frame 19. side plate 20,2
0, and is prevented from coming off with a washer 24 and a screw 25. Furthermore, the interval between the ratchet wheels 17 is the frame 19.
They are maintained at equal intervals by protruding spacers 45 formed in the . Therefore, since the ratchet wheel is fitted onto the shaft and interposed between each spacer during assembly, a dedicated frame is essential, resulting in poor productivity and the need to connect the individual ratchet wheels and vibration valves. There are drawbacks such as the positioning support means being troublesome and the ease of assembly.

奏するオルゴールが提供できる。 Since the present invention is constructed as described above, conventional mass-produced frames can be used as is, and a ratchet unit can be used instead of a drum unit, so mass production equipment can be utilized and costs can be reduced significantly. We can provide music boxes that use discs or cards as media. In addition, the ratchet unit can be easily replaced with a drum unit because a plurality of ratchet wheels are positioned on the spacer, and the spacer allows the ratchet unit to be easily positioned stationary on the rotating shaft. Also, since the spacer is common to each ratchet wheel, the number of parts is small and assembly is easy. Furthermore, by removing the rotation prevention plate of the spacer, it is easy to change from a disk type to a card type. In addition, since the ratchet unit has approximately the same size as the drum unit and is configured to be replaceable, it can be made smaller and, like the conventional drum type, can be used in a wide range of applications. Moreover, it is possible to provide a music box that plays with excellent media such as discs and cards.
勿論本考案の爪車ユニツトを大きくするとそれ
に応じたフレームが必要となるが、ユニツトを支
持するので上記と同様に簡単な構成で良い。 Of course, if the ratchet unit of the present invention is increased in size, a corresponding frame will be required, but since the unit is supported, a simple structure similar to the above may be sufficient.
