Abstract

(57) [Summary] [Object] The present invention relates to a pachinko machine, and more particularly to driving a hammer using a variable reluctance type step motor. [Structure] In the pachinko launching device according to the present invention, the hammer (8) provided on the variable reluctance type step motor (20) is always urged in one direction by the spring (31), and is excited to store the spring (31). However, the hammer (8) is returned by the spring (31) when it is not excited, and the ball (32) is fired.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pachinko launcher, and more particularly to a novel improvement for driving a hammer using a variable reluctance step motor.

[0002]

[Prior art]

 As a pachinko launcher structure of this type that has been conventionally used, for example, the structure shown in FIG. 4 is used. That is, a reference numeral 20 in FIG. 4 is a synchronous motor having a cam 21, and a hammer 8 corresponding to the cam 21 is rotatably provided in a direction of an arrow A through a shaft support portion 22. There is. The return spring 23 connected to the hammer 8 is connected to the operation handle 25 via a pulley 24, and the pulley 24 is biased by a biasing spring 26. Therefore, in the above-described configuration, the hammer 8 is reciprocally rotated in the direction of arrow A by the rotating cam 21, and the striking strength of the handle 8 is adjusted by operating the operating handle 25.

[0003]

[Problems to be solved by the device]

 Since the conventional pachinko launcher structure is configured as described above, the following problems exist. In other words, since the hammer was hit by the cam, a synchronous motor and cam were required, the structure was complicated, and it was extremely difficult to reduce the size and cost.

The present invention has been made to solve the above problems, and in particular, an object of the present invention is to provide a pachinko firing apparatus in which a hammer is driven by using a variable reluctance type step motor. And

[0005]

[Means for Solving the Problems]

 The pachinko launching device according to the present invention includes a variable reluctance step motor provided on a mounting plate, a hammer attached to a rotary shaft of the variable reluctance step motor, and a rotation range of the hammer provided on the mounting plate. It has a stopper for setting and a spring that constantly urges one end of the hammer in one direction, and the hammer retreats against the bias of the spring when the variable reluctance type step motor is excited. However, the ball is fired by being rotated by the bias of the spring when it is not excited.

[0006]

[Action]

 In the pachinko machine according to the present invention, by exciting the variable reluctance type step motor, the hammer rotates downward against the bias of the spring, and the spring is charged. In this state, by making it non-excited, the hammer can be rotated upward by the spring to shoot the ball.

【Example】

 Hereinafter, preferred embodiments of a pachinko machine according to the present invention will be described in detail with reference to the drawings. The same or equivalent parts as those of the conventional example will be described using the same reference numerals. A reference numeral 1 in FIG. 1 denotes a mounting plate, and the mounting plate 1 is provided with a known variable reluctance type step motor 20.

A hammer 8 is integrally fixed to a rotary shaft 20a of the variable reluctance step motor 20 via a nut 20b, and a rotation range θ of the hammer 8 is attached to the mounting plate 1. A stopper 30 for determining is provided.

The stopper 30 is located above the variable reluctance step motor 20, and when the variable reluctance step motor 20 is in a non-excited state, a spring 31 provided at one end of the hammer 8 constantly After being urged in one direction to excite the variable reluctance type step motor 20 and rotate the hammer 8 to the position indicated by the solid line against the urging of the spring 31 (spring 31 is stored). When energized, the hammer 8 fires the ball 32 along the guide 33 by the bias of the spring 31.

The variable reluctance type step motor 20 is configured to be freely operated by an operation handle 25 provided on the front surface side of the mounting plate 1. The variable reluctance type step motor 20 is in a non-excited state. Since the hammer 8 does not have a non-excitation torque, the hammer 31 can be returned very smoothly by the spring 31, the turning angle θ is always constant, and variations in ball skipping can be eliminated.

[0011]

[Effect of device]

 Since the pachinko machine according to the present invention is configured as described above, the following effects can be obtained. In other words, since the variable reluctance type step motor is used, the hammer returns smoothly when there is no excitation, there is no variation in ball jumping, and the ball is always fired with the spring energy fully utilized. You can
