  Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. In the drawing, portions not related to the description may be omitted.

As shown in FIG. 1, the driving device 10 for the hand-held music box 20 according to the embodiment of the present invention can drive the hand-held music box 20 to electrically drive the existing hand-held music box 20.
That is, the electric music box system 30 is configured by the drive device 10 and the existing hand-driven music box 20.

  The hand-driven music box 20 includes a case 202, a music box movement 204 fixed to the case 202, and a hand-turning handle 206 that rotates about the rotation axis AX <b> 1 (see FIGS. 2 and 3) and drives the music box movement 204. Yes.

  The music box movement 204 is driven by a handwheel handle 206 and can read a paper tape (not shown). The music box movement 204 can play music recorded on the read paper tape.

  The handwheel handle 206 extends to the outside of the case 202 as shown in FIG. As shown in FIG. 5, the handwheel handle 206 includes a first shaft portion 210a that rotates about a central axis (rotation axis AX1), and a first shaft portion from the distal end portion of the first shaft portion 210a when viewed from the front. An arm part 214 extending in the radial direction of 210a, a second shaft part 210b extending in a direction in which the first shaft part 210a extends from the tip part of the arm part 214, and a tip side of the second shaft part 210b. And a grip portion 212 that can rotate around the second shaft portion 210b (in the direction of the arrow shown in FIG. 5).

As illustrated in FIG. 1, the drive device 10 includes a pulley (an example of a power transmission component) 102, a motor unit (an example of a power generation unit) 120, and a belt 130.
The pulley 102 can transmit power for driving the handwheel handle 206. As shown in FIG. 2, the pulley 102 is attached to a position closer to the base side (case 202 side) of the handle 206 than the grip portion 212, and rotates around the rotation axis AX1.

As shown in FIGS. 4 (A) and 4 (B), the pulley 102 is a circular member when viewed from the front, and has a groove 112 on which the belt 130 is hung on the outer peripheral surface.
Further, a circular hole 114a and a long hole 114b extending in the radial direction from the hole 114a are formed at the center of the pulley 102. The size of the hole 114 a is set larger than the outer shape of the grip portion 212 of the handwheel handle 206. The width of the long hole 114 b is set larger than the diameter of the arm portion 214.
Further, as shown in FIGS. 4B and 4C, a mounting hole 118 is formed on the back side of the pulley 102. The first mounting component 104a and the second mounting component 104b shown in FIG. 5 are inserted into the mounting hole 118.

Each of the first attachment component 104a and the second attachment component 104b is a semi-cylindrical member. In the first attachment component 104a and the second attachment component 104b, grooves 105a and 105b (see FIG. 6) in which the first shaft 210a is received are formed on the flat surfaces 106a and 106b constituting a part of the outer peripheral surface, respectively. Has been.
Therefore, the first mounting component 104a and the second mounting component 104b can constitute a cylindrical mounting component 104 (see FIG. 7) by combining these flat surfaces 106a and 106b so as to face each other. A hole through which the first shaft 210a passes is formed in the central portion of the attachment component 104 by the combined grooves 105a and 105b.
The pulley 102 is attached to the handwheel handle 206 through the attachment part 104.

As shown in FIG. 1, the motor unit 120 is disposed at a location different from the hand-held music box 20 and can generate power for driving the hand-handle handle 206.
The motor unit 120 includes a motor 121, a pulley 122, and a speed controller 123.
The motor 121 is a DC motor, for example, and power is supplied by a battery (not shown).
The pulley 122 is attached to the output shaft of the motor 121.
The speed controller 123 can control the rotation speed of the output shaft of the motor 121 to a desired magnitude.
The motor 121 and the speed controller 123 are housed in the same case.

  The belt 130 is hung on the pulley 102 and the pulley 122.

  Next, a method for attaching the driving device 10 will be described. The driving device 10 is attached to an existing hand-held music box 20 according to the following process. However, when possible, the respective steps may be performed in a reversed order or may be performed in parallel.

(First step)
The hand-held music box 20 and the driving device 10 are prepared.

(Second step)
The first attachment component 104a and the second attachment component 104b are combined with the first shaft portion 210a of the handle 206 by hand (see FIG. 6).
Specifically, the flat surface 106a of the first mounting component 104a and the flat surface 106b of the second mounting component 104b are opposed to each other, and the first shaft portion 210a is formed with the grooves 105a and the second formed in the first mounting component 104a. Is inserted into a groove 105b formed in the mounting part 104b.

(Third step)
As shown in FIG. 7, with the attachment hole 118 (see FIGS. 4B and 4C) as the back side, the grip part 212 of the handle 206 is passed through the hole 114 a formed in the pulley 102. Since the size of the hole 114 a is larger than the outer diameter of the grip portion 212, the pulley 102 can be inserted from the front end side of the grip portion 212.

(Fourth process)
The first mounting component 104a and the second mounting component 104b are configured by the first mounting component 104a and the second mounting component 104b in the mounting hole 118 of the pulley 102 in a state where the first mounting component 104a and the second mounting component 104b are combined with the first shaft portion 210a. A cylindrical assembly component 104 is inserted. Note that the distal end side (the second shaft portion 210b side) of the arm portion 214 is accommodated in the long hole 114b.
As a result, the pulley 102 is restricted from moving in the radial direction of the first shaft portion 210a.

(Fifth step)
The fixing plate 115 is attached to the pulley 102 using the screw 116 (see FIG. 5). The arm portion 214 of the handwheel handle 206 is sandwiched between the fixing plate 115 and the attachment component 104.
As a result, the pulley 102 is also restricted from moving in the axial direction of the first shaft portion 210a (the direction in which the rotation axis AX1 extends), and is fixed to the handwheel handle 206.

(Sixth step)
The belt 130 is hung on the pulley 102 and the pulley 122, and the motor unit 120 is disposed at a position where the tension of the belt 130 becomes an appropriate magnitude (see FIG. 1).

Thus, according to the driving device 10 of the hand-operated music box 20 attached according to the first to sixth steps, the power of the motor 121 is transmitted through the belt 130 and the pulley 102, and the hand-operating handle 206 is driven. The existing hand-held music box 20 is electrified.
Further, since the pulley 122 is attached to the base side with respect to the grip portion 212, it is possible to perform by manually turning the handle 206 manually. That is, the original manual performance of the hand-held music box 20 and the performance by the driving device 10 can be enjoyed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and all changes in conditions and the like that do not depart from the gist are within the scope of the present invention.
The hand-held music box may be any music box as long as it is a music box that manually drives the hand-operated handle.
The power transmission component is not limited to the pulley 102, and may be any power transmission component that is attached to the base side of the handwheel 206 from the grip portion 212 and rotates around the rotation axis AX1.
