  (1) A music box apparatus according to the present invention has a pin implanted in accordance with a music piece, a rotating member that rotates in a normal rotation direction, a rotating shaft that holds the rotating member on a base, and the rotating pin. A music box device comprising: a diaphragm having a comb-like vibration valve that emits sound when bounced; and a rotary drive shaft that rotates the rotary member in the normal rotation direction, wherein one end of the rotary drive shaft is at the base The other end of the rotary drive shaft extends in the opposite direction to the one direction, and the other end is one end of the rotary drive shaft of another music box device having the same structure. Is inserted to form a hollow portion that holds the two rotational drive shafts on the same axis.

  Therefore, it is possible to provide a connected music box device in which a plurality of music box devices are connected without using a complicated mechanism.

  (2) In the music box device according to the present invention, the rotating member is provided with a start position mark indicating a position of a pin serving as a start position of the music, without rotating the rotation drive shaft, The rotation drive shaft and the rotation member are related so that the rotation member can be rotated in the forward rotation direction. Therefore, even after each music box device is connected, the music start position of each music box device can be adjusted.

  (3) In the music box device according to the present invention, the rotational drive shaft and the rotational shaft are orthogonal to each other. Thus, since the said rotational drive shaft is located in the direction orthogonal to the said rotational axis, each music box apparatus can be connected with the direction.

  (4) In the music box device according to the present invention, the rotating member is cylindrical. Therefore, it is possible to connect a plurality of music boxes whose cylinders are rotating.

  (5) In the music box device according to the present invention, the rotating member has a disk shape. Therefore, it is possible to connect a plurality of music boxes having a disk-shaped rotating portion.

  (6) In the music box device according to the present invention, the hollow part has a holding means for holding the hollow tube and the one end of the other inserted music box. Accordingly, the one end inserted into the hollow tube can be held firmly.

  (7) A connected music box device according to the present invention is configured such that any one of the music box devices is a first music box device, and a music box device having the same structure as the first music box device is a second music box device. The one end of the music box device is inserted into the hollow portion of the second music box device to be firmly held, and the other end of the first music box device is driven to rotate the rotation drive shaft thereof. Insert. Therefore, it is possible to provide a connected music box device in which a plurality of music box devices are connected without using a complicated mechanism.

  In this specification, “hold” means holding when one rotary drive shaft is rotated so that the other rotation coaxial axis rotates in the same manner.

It is a figure which shows the side surface and upper surface of a music box apparatus. It is a figure which shows the connection music box apparatus 20 which connected the music box apparatus 1. FIG.

(1. First embodiment)
An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows individual music box devices 1 constituting a connected music box device. FIG. 1A is a top view of the music box device 1. The music box device 1 has almost the same structure as a general hand-held music box, and includes a base 2, a drum 3 as a rotating member, a diaphragm 5, a rotary drive shaft 10, and a plurality of pins (see FIG. Not shown).

  On the base 2, a drum 3 is rotatably held by a rotation shaft 6. A plurality of pins are implanted on the cylindrical surface 3a of the drum 3 in accordance with the music (not shown). The vibration plate 5 has a comb-like vibration valve 5a. The vibration valve 5a is attached to a plurality of pins provided on the cylindrical surface 3 by rotating the drum 3 in the direction of arrow α (hereinafter referred to as a positive direction). Plays a sound when played.

  One end 10 a of the rotary drive shaft 10 is extended so as to protrude from one direction of the base 2. The other end of the rotary drive shaft 10 is provided with a pipe portion 12 that is a hollow portion protruding from the opposite side to the one direction. The inner diameter of the pipe portion 12 is slightly larger than the outer diameter of the one end 10a. A handle 21 shown in FIG. 1C is inserted into the pipe portion 12. The inserted handle 21 is fixed by the screw 13. The rotation drive shaft 10 is rotated by rotating the handle 21, and the rotation drive shaft 10 rotates the drum 3. This produces a sound as a music box.

  The rotation drive mechanism of the drum 3 and the rotation drive shaft 10 is the same as the conventional one, but will be described briefly. A worm gear is fixed to the rotary drive shaft, and this worm gear meshes with a worm gear fixed to the drum 3. Thus, when the rotary drive shaft 10 is rotated, the drum 3 rotates. Note that the drum 3 incorporates a ratchet function so that only normal rotation is performed, as in the conventional hand-driven music box device.

  A plurality of music box devices 1 can be connected and used. FIG. 2 shows a connected music box device 20 in which six music box devices 1a to 1f are connected. One end 10a of the music box device 1a is inserted into the pipe portion 12 of the music box device 1b. One end 10a of the music box device 1a is fixed with a screw 13b. A handle 21 is inserted and fixed to the pipe portion 12 of the music box device 1a. Therefore, when the handle 21 is rotated, the connecting drive shafts of the six connected music box devices 1a to 1f rotate in synchronism, thereby playing music.

  In the present embodiment, the pins on the drum 3 of the music box devices 1a to 1f are provided so as to form a united music when the music box devices are moved in synchronization.

  A method for synchronizing the start of music will be described. As already described, the drum 3 is provided with a ratchet function, and restricts the rotation direction to the normal rotation direction. Specifically, when the rotary drive shaft 10 rotates, the drum 3 also rotates. However, the drum 3 can be rotated in the forward direction independently of the rotary drive shaft 10 by a ratchet mechanism provided on the drum 3. Using such a function, the drum 3 can be rotated and set at an arbitrary position even when the rotary drive shafts 10 of the plurality of music box devices 1 are connected. As shown in FIG. 1A, the drum 3 is provided with a start position mark 31 that indicates the position of a pin that is the start position of the music. In the present embodiment, the music played by the plurality of music box devices 1a to 1f can be synchronized by matching the start position mark 31 provided on the drum 3 side with the tip of the diaphragm 5.

(2. Other embodiments)
In the said embodiment, although the case where the music box apparatus 1 was a cylindrical type was demonstrated, a disk type may be sufficient.

  In the present embodiment, a shaft having a circular cross section of the rotational drive shaft 10 is inserted into the hollow portion 12 and is secured by screws 13, but the rotational drive shafts 10 are connected to each other. Any device that can transmit the rotational driving force may be used. For example, one end of the rotational driving shaft 10 may be formed in a semicircular shape, and the inner shape of the hollow portion 12 may be matched with the semicircular shape.

  The mechanism for synchronizing the plurality of music box devices is not limited. For example, the start mark may be provided not on the side surface of the drum but on another surface.
