Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a rotating body formed of an elastic material in the ejection part of the guide rail, and the rotating body and the guide rail bite the ball, and the rotating body The present invention relates to a ball firing device for a new electric pachinko machine configured to fire balls using rotational force.

[Conventional technology]

As is well known, in conventional pachinko machines, balls supplied to a firing position on a guide rail are strongly hit by a hitting lever, and the balls are fired by the instantaneous impact force. On the other hand, as disclosed in Japanese Patent Publication No. 55-38156, for example, a throwing arm is rotatably provided at the launching end of the guide rail, and the throwing arm is swung by an electric device to cause the balls to be hit onto the game board. There are also known electric pachinko machines that fire the ball.

[Problem to be solved by the invention]

Among the conventional techniques, the former has a fatal flaw for pachinko machines in that accurate shots cannot be fired unless the tip of the striking lever and the center of the ball are aligned correctly. Adjustment requires highly sophisticated skills, and there are problems with the work, such as the time it takes to assemble the pachinko machine.Furthermore, the impact and noise generated during hitting can sometimes affect the psychological aspects of the players. However, there was a strong desire for some sort of improvement measure, as it was causing unnecessary trouble.

On the other hand, in the latter case as well, the ball is fired by the inertia of the ball when the swinging motion of the throwing arm stops, so the throwing arm collides with the stopper each time it swings. There was a problem in that it generated noise.

[Means to solve the problem]

The present invention has been made in view of the above-mentioned problems, and includes a table frame having a ball tray and an operation handle on its front surface, and a guide rail that is attached to the inner surface of the table frame and has a firing section on its surface. The game board and
A rotary body made of an elastic material, disposed above the ejection part of the guide rail with a gap slightly smaller than the diameter of the balls supplied from the ball receiving tray, and a motor for driving the rotary body. The rotation of the operating handle drives a motor to rotate a rotary body, and the rotation of the rotary body causes balls supplied to the firing section to be fired onto the game board. .

[Effect]

When the player operates the operating handle, the motor is driven and the rotating body is rotated. As the rotary body rotates, the ball is caught in the gap between the rotary body and the ejection portion of the guide rail, and is ejected onto the game board by the rotational force and compressive force of the rotary body.

〔Example〕

An example of the embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is the main body of the pachinko machine, 2 is its front frame, and 3 is a game board that is attached to the inner surface of the table frame 2 so as to close the window hole 4. A spiral guide rail 5 is installed in front of these. Reference numeral 6 denotes a front plate that covers the lower part of the window hole 4, and a ball receiving tray 7 for storing balls is attached to the surface of the front plate. Reference numeral 8 denotes a supply port which is opened and communicated from the ball receiving tray 7 to the ejection section 10 of the guide rail 5 via the ball feeding device 9.

2 to 4 show the main structure of the present invention,
A rotating body 11 made of an elastic material is installed directly connected to the drive shaft 13 of a motor 12, and this rotating body 11 is placed above the firing section 10 of the guide rail 5 at a distance slightly smaller than the diameter of the ball. A guide rail 14 is interposed between the firing unit 10 and the supply port 8, and balls 15 are intermittently supplied one by one from the supply port 8 by the ball feeding device 9 and are fired via the guide rail 14. 10.

The motor 12 is fixedly installed on the back surface of the mounting plate 16, and its drive shaft 13 protrudes from the front surface of the mounting plate 16. It is preferable that the guide rail is fixedly installed on a base portion 17 that is integrally provided on the front surface of the mounting plate 16, and that the guide rail is curved downward in an arc shape. And motor 1
2 is electrically connected to the operating handle 18, and by rotating the operating handle 18, the motor 12 is started, and by operating the operating handle 18, the driving speed of the motor 12 can be freely controlled, thereby changing the rotational speed of the rotating body 11.

Since the present invention has the above-described configuration, when the motor 12 is started by rotating the operating handle 18, the rotating body 11 continuously rotates and the ball feeding device 9 is started at the same time, so that the balls 15 are sent to the ball receiving tray. 7 intermittently one by one is delivered to the supply port 8, rolls on the guide rail 14, and falls to the end of the ejection part 10. The hitting ball 15 moves when it is caught between the rotating body 11 and the guide rail 5 due to the rotation of the rotating body 11 in the firing section 10, and when it leaves the rotating body 11, it is affected by the rotational force and pressing force of the rotating body 11. It is fired instantly. The strength of the firing force of the ball 15 can be controlled by adjusting the rotational speed of the rotating body 11.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

Since the rotating body 11 only needs to be placed above the ejection part 10 of the guide rail 5 at a predetermined biting distance according to the diameter of the hitting ball 15, installation is extremely easy simply by determining the mounting position of the mounting plate. Can be done.

Therefore, the present invention not only has a simple structure and is easy to install and deploy without requiring much labor, but compared to conventional batting mallets, the installation site does not require much space, and the firing of balls makes almost no sound. Therefore, it has the advantage of being quiet and free from noise generation.
