The groove 133 is screwed so as to come into contact with the side portion of the groove 133 for fastening. As a result, the other end of the fixed shaft 13 is fixed to the rotary mount 14.
In the present embodiment, the rotary mount 14 is the L-shaped base 14
1 is fixed so as to be located in the direction opposite to the arrangement direction of the rod bell 17.

The rotary mount 14 is driven by a control unit (not shown) of the motor 12 so that the motor rotary shaft 12 can be driven.
It rotates by the rotational force transmitted to 1, and the seven bells 16-
1 to 16-7 are driven to rotate to a plurality of angular positions where they are arranged and stop at the angular positions. That is,
The rod bells 16-1 to 16-7 as hit objects are arranged corresponding to a plurality of angular positions of the rotary mount 14.

The actual striking mechanism 15 includes a striking body 151 and a supporting body 1.
52, the solenoid 153, the rotating shaft 154, and the coil spring 155 are main components.

The striking body 151 has a structure in which it is bent so as to have an approximately L shape in the middle thereof, a stem 151a is provided at one end thereof, and an operating shaft 153a of a solenoid 153 is attached at the other end thereof. The part 151b is formed. The solenoid 15 is attached to the mounting portion 151b.
The tip of the third operation shaft 153a is attached.

The support member 152 has a flat plate shape having a U-shaped central portion at one end, and has a flange portion 152b formed so as to be orthogonal to one end portion of the flat plate portion 152a. The other end is fixed to the vertical side surface of the L-shaped base portion 141 of the rotary mounting base 14 so that the collar portion 152a faces the rod bell 17 side, and the solenoid 153 operates on one surface side of the flat plate portion 152a. The shaft 153a is attached so as to face upward. Further, at the tip of the collar portion 152b,

First, the mounting operation of the fixed shaft 13 and the adjusting operation of the rotary mounting base 14 will be described. For example, in a state in which the tip of the motor rotation shaft 121 formed in a flat (for example, D-cut) shape is inserted into the first insertion hole 131 formed at one end side of the fixed shaft 13, the first screw 1
34 is screwed into the first fixing screw hole 132 so that the tip portion of the first screw 134 abuts on the flat portion of the motor rotation shaft 121 to be fastened. As a result, the fixed shaft 13 is fixed to the motor rotating shaft 121.

Also, with the other end of the fixed shaft 13 inserted in the second insertion hole 142 formed in the one end face side of the rotary mounting base 14, the second screw 144 is used as the second fixing screw. The tip of the second screw 144 is screwed into the hole 143 in such a manner that the tip of the second screw 144 abuts against the side of the fixed shaft 13 on the other end side and is temporarily fixed. In this state, for example, the motor 12 is rotationally driven by a control unit (not shown), and the rotary mount 14 is rotated to a plurality of predetermined angular positions and stopped at the predetermined angular positions. Then, a plurality of bells 16-1 to 16-7 arranged around the doll body 20 are sequentially struck by the striking body 151 driven by the actual striking mechanism 15 in correspondence with the plurality of angular positions. It

In practice, due to backlash and mounting error of the motor 12, even if the positions of the bell bell 151 and the bells 16-1 to 16-7 are adjusted only at one angular position, all the bells 16-1 to 16-7 are adjusted. Uniform adjustment in the angular position is difficult. Therefore, at the time of this temporary fixing, the striking body 151 and the bells 16-1 to 16-7 at all angular positions.
Is adjusted so that the positional relationship with In other words, the rotary mount 14 moves smoothly and stops accurately at a plurality of angular positions, and one doll body 20 strikes a plurality of bells 16-1 to 16-7 stably and accurately. Is finely adjusted using the second screw 144. Then, when the fine adjustment is completed, the second screw 144 is securely fastened,
The fixed shaft 13 is fixed to the rotary mount 14. After that, the normal rotation control allows the rotary mount 14 to move smoothly and to be accurately and smoothly stopped at a predetermined angular position among a plurality (7 in this embodiment).

Is struck and a bell sound of a predetermined scale is emitted. At this time,
The coil spring 155 is not in a stable state and is in an extended state.

Then, the solenoid 153 is de-energized. As a result, the operating shaft 153a is linearly returned to the initial state, and the other end of the striking body 151 is pushed down. At this time, the elastic force of the coil spring 155 trying to return to a stable state assists the pushing down operation of the other end of the striking body 151. As a result, as shown in FIG.
The bell 151 rotates clockwise around 4, and one end of the bell 151 moves toward a position away from the bell 16-1.
