DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball hitting structure, and more particularly to a novel improvement for reducing noise when hitting a ball by providing a cushioning material between a rotating shaft and an arm.

[0002]

2. Description of the Related Art Conventionally, there are various types of pachinko balling structures of this kind which have been used. Among them, a typical one is generally shown in FIGS. 4 to 6. . That is, a motor indicated by reference numeral 1 in FIGS. 4 to 6 is a motor, and a notch 2 a formed on an output shaft 2 of the motor 1 has an arm shaft 4 of an arm 3 having a substantially moon-shaped overall shape. Is fixed via a locking screw 5, and the arm 3 is joined via a shaft support 6 to a column piece 7 a of a punching lever 7 provided to be reciprocally rotatable. A spring member 9 is stretched between the ejection lever 7 and the locking portion 8a of the main body 8. Therefore, when the arm 3 is rotated by the motor 1, the arm 3 functions as a cam, and the driving arm 7 reciprocates as shown by the arrow A. The tip 7a of the driving arm 7 As a result, the pachinko ball 7A can be hit intermittently.

[0003]

Since the conventional pachinko ball hitting structure is configured as described above, the vibration of the arm is directly transmitted to the output shaft, and when the ball is hit at high speed, the sound is loud. It was impossible to get a low noise pachinko machine.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and in particular, a pachinko ball in which a noise at the time of balling is reduced by providing a cushioning material between a rotating shaft and an arm. It is intended to provide a striking structure.

[0005]

A pachinko ball hitting structure according to the present invention hits a pachinko ball by a hitting lever via an arm driven by rotation of a rotating shaft rotated by rotation of a motor. In the pachinko ball striking structure, a first cushioning material is provided between the rotation shaft and the arm.

[0006] More specifically, a pin provided on the rotating shaft and provided in a direction perpendicular to the axial direction of the rotating shaft;
The structure includes a second cushioning member provided on the pin.

[0007] More specifically, the rotary shaft is constituted by an output shaft of the motor.

[0008] More specifically, the rotary shaft is constituted by a deceleration output shaft of a speed reducer provided in the motor.

[0009]

In the pachinko ball hitting structure according to the present invention,
Since the cushioning material is provided between the rotating shaft and the arm and between the pin and the arm, even when the ball striking lever is snapped by the arm, the vibration is absorbed by the cushioning material, so that the vibration and noise transmitted to the entire pachinko machine are provided. Can be greatly reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a pachinko ball hitting structure according to the present invention. The same or equivalent parts as those in the conventional example will be described with the same reference numerals. 1 to 3 show a pachinko ball hitting structure according to the present invention.

In the figure, a motor indicated by reference numeral 1 is a motor. An output shaft 2 of the motor 1 is provided with a first cushioning member 10 made of a cylindrical elastic body or the like.
A pin 11 is fixedly mounted through the output shaft 2 in a direction perpendicular to the axial direction of the output shaft 2.

The pin 11 is provided with a second cushioning material 12 of the same quality as the first cushioning material 10. On the outer periphery of the first cushioning material 12, an arm of the arm 3 having the same overall shape is provided. The shaft 4 is fitted, and a notch 4 a formed in the axial direction of the arm shaft 4 is joined to the outer periphery of the second cushioning material 12.

Therefore, the output shaft 2 and the arm 3 are not directly joined to each other, but are provided via the cushioning members 10 and 12. The output shaft 2 acts as a rotation shaft for rotating the arm 3. The rotation shaft is not limited to the output shaft 2. For example, although not shown, a well-known deceleration provided on the motor 1 is provided. It can also be the deceleration output shaft of the machine. Further, the arm 3 can be directly bonded to the first cushioning member 10 without using the pin 11.

The arm 3 is configured to actually hit a slingshot ball by using a balling lever 7 as shown in FIG.

[0015]

The pachinko ball striking structure according to the present invention is constructed as described above, so that the following effects can be obtained. That is, since the cushioning material is interposed between the rotating shaft and the arm that comes into contact with the balling lever, vibration and noise generated during balling can be significantly reduced, and a low-noise pachinko machine is obtained. be able to.
