DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention covers the entire back surface of a game board mounted on a pachinko machine, and places a winning ball collecting passage at a lower portion and a winning ball at the end of the winning ball collecting passage below the pachinko machine. A mechanism plate in a pachinko machine in which a winning plate passage for discharging is formed in a communicating shape, wherein an inner wall surface of each passage is cleaned from outside without removing the mechanism plate, or a foreign substance such as a screw is removed. It is about.

[0002]

2. Description of the Related Art Conventionally, for example, a mechanism plate that covers the entire back surface of a game board is provided so as to be openable and closable, and a ball shifting space is formed between the mechanism plate and the rear face of the game board. A winning ball collecting passage is formed in the lower part of the space, and further, the winning balls are arranged in a line at the end of the winning ball collecting passage, sent to the winning ball processing device, and finally discharged below the pachinko machine. There is a pachinko machine that has a winning ball passage.

[0003]

However, pachinko balls are usually liable to adhere to the player's dirt, dust, and dust, and are automatically cleaned, but not sufficient. Therefore, when the pachinko balls with dust and the like enter the winning opening of the game board as winning balls, these winning balls are moved to a winning ball gathering passage provided in a lower portion of a mechanism plate that is freely openable and closable on the back of the game board. It is collected, further aligned and sent to a winning ball processing device via a winning ball passage, and finally discharged below a pachinko machine. Thus, when running the pachinko machine for a long time, the winning ball set through Michimata has finger marks adhered to the winning ball on the inner wall surface of the winning ball path, winning ball by dust or the like adheres during flow And the ball may be jammed in some cases. In addition, when a pachinko machine is newly installed on an island stand, foreign matter such as screws for mounting may accidentally fall into the winning ball collecting passage of the mechanism plate, and in this case, the foreign matter also interferes. , There was a risk that the ball would be packed. Therefore, in order to avoid these states, open the mechanism plate one by one,
Although so as remove the cleaning or foreign substances to such wiping the inner wall surface of each of the passages is forced to cumbersome and much labor and time to the task that the electrical wiring or to open and close relationship on mechanism board there There was a problem that. Accordingly, the present invention has been made in view of the above problems, and provides a mechanism plate in a pachinko machine capable of easily and efficiently cleaning the inner wall surface of each passage or removing foreign matter without opening and closing the mechanism plate. The purpose is to do.

[0004]

In order to achieve the above object, a mechanical plate in a pachinko machine according to the present invention covers a whole back surface of a game board mounted on the pachinko machine and has a ball-adjusting space between the rear face of the game board. A mechanism plate provided with a prize ball collecting passage at a lower portion of the ball approaching space, and a prize ball passage for discharging a prize ball to a lower portion of the pachinko machine at an end portion thereof in a communicating manner. Corner of ball collection passage or winning ball passage
Section, which communicates with the winning ball collecting passage or the winning ball passage.
Inside the opening groove to remove foreign substances such as screws and dust inside
It is configured to have an L-shaped cross section from the side wall to the outer wall .

[0005]

The flow of winning ball collecting passage or the winning balls set that by the inner wall surface of the winning ball passage communicating with the passage winning ball GORE <br/> Mi or dust adheres to winning ball in the lower portion of the working mechanism by plate When it gets worse, a cleaning tool such as a cotton swab is inserted into each passage from the opening groove without opening the mechanism plate to clean the inner wall surface. In addition, bi in the passage
When a foreign material such as metal enters and the ball is jammed, a key-like thin rod is inserted through the opening groove to scrape the foreign object out of the opening groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mechanical plate in a pachinko machine according to the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a pachinko machine 1 to which the present invention is applied. In the drawing, reference numeral 2 denotes a machine frame. A game board mounting frame 4 is fixed to the back of a front frame 3 mounted on the machine frame 2, and a game board 5 is mounted on the game board mounting frame 4. On one side of the game board mounting frame 4, a mechanical plate 6 made of a synthetic resin that covers the entire back surface of the game board 5 is mounted so as to be freely opened and closed. Mechanism plate 6 corresponding to the back of game board 5
A ball approach space 7 is formed in front of the ball approach space 7, and below the ball approach space 7, a winning ball collecting passage 8 into which the winning balls collected by the ball approach space 7 fall. Therefore, the winning ball collecting passage 8 on surfaces of the inner wall 8a is a inner bottom surface is where the downward in one direction.

On the other hand, a prize ball tank 9 for storing a prize ball is provided on the upper rear surface of the mechanism plate 6.
An outlet gutter 10 for aligning and flowing down the prize spheres is provided below. A vertical supply gutter 11 is provided downstream of the outlet gutter 10, and a prize ball dispenser 12 is connected to a lower end of the supply gutter 11. Furthermore, a prize ball dispensing device 12
A prize ball discharge gutter 13 for guiding the prize balls paid out to a hitting ball supply tray (not shown) in front of the pachinko machine 1 is provided below. Reference numeral 14 denotes a storage gutter for wiring provided at a lower portion of the rear surface of the mechanism plate 6, the rear surface of which is attached by a cover body 15. The cover body 15 has an insertion hole 1 having a protrusion 15a protruding from one side end provided on a side wall of a prize ball discharge gutter 13.
6 and locked, and the other side is attached by screwing 17.

At the end of the prize ball collecting passage 8, there is formed a prize ball passage 19 for arranging the prize balls in a line and discharging the prize balls below the pachinko machine 1. The winning ball passage 19 inner side walls 19a face curved in a generally [shape. On the way, a winning ball processing device 18 mounted on the lower portion of the rear surface of the mechanism plate 6 is provided. 20 is a winning ball passage 19
This is a prize ball detector provided upstream of the prize ball processing device 18.

The winning ball processing device 18 is a winning ball processing device 2
