Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism board for a pachinko machine, in which a front side wall abutting against a back surface of a game board is provided separately in a winning ball collecting passage provided at a lower portion of the mechanism board. Is.

[0002]

2. Description of the Related Art Generally, on the back surface of a game board mounted on a pachinko machine, a mechanism plate made of synthetic resin covering the entire back surface is provided so as to be openable and closable. Further, the mechanism plate forms a ball-pushing space with the game board, and a prize-ball collecting path for collecting the prize-balls and sending them to the prize-ball processing device is provided in a lower part of the ball-pitch space. There is. By the way, in the winning ball collecting passage, since it is difficult to form the front side wall abutting against the back surface of the game board integrally with the mechanism plate, the pachinko machine is provided separately from the mechanism plate. There is.

[0003]

However, since the front side wall is attached to the mechanism plate by fixing it at a plurality of places with screws, it takes a lot of time and labor, and the mounting work is troublesome. However, there was a problem that the workability was poor and the production cost was high. Therefore, the present invention has been made to solve the above-mentioned problems, and enables a mechanism plate to be attached without using any screws, thereby simplifying the attachment work and improving the workability of a pachinko machine. The purpose is to provide a mechanical plate.

[0004]

In order to achieve such an object, the mechanism plate of the pachinko machine of the present invention is arranged on the back side of the game board so as to cover the whole, and a ball is provided between it and the back surface of the game board. An award space is formed and a prize ball collecting passage for collecting prize balls is provided in a lower portion of the ball attracting space, and a front side wall abutting the back surface of the game board in the prize ball collecting passage is provided separately. In the mechanism plate of the pachinko machine described above, an engaging recess is provided on one side of the front side wall and a locking portion is provided at the lower end edge, and the mechanism plate is engaged with the engaging recess and the locking portion at positions corresponding to each other. The front side wall is attached to the mechanism plate by providing a mating portion and a locking concave portion, and engaging or locking the engaging portion and the engaging concave portion and the locking portion and the locking concave portion, respectively. .

[0005]

By engaging or locking the engaging portion and the engaging concave portion and the locking portion and the locking concave portion, which are provided correspondingly, with each other, the front side wall can be easily removed without being screwed to the mechanism plate. The attachment work is thereby simplified and the workability is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mechanical board of 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 to which the present invention is applied. In the figure, 1 is a machine frame of a pachinko machine 2, 3 is a front frame, and 4 is a game board mounting frame fixed to the back surface of the front frame 3. Yes, the game board 5 is attached to the game board mounting frame 4. FIG. 2 shows a mechanism plate 6 arranged on the back side of the game board 5 so as to cover the whole.

The mechanism plate 6 is made of a synthetic resin material, and a large window opening 7 is opened in the center thereof, and a prize ball is held on the front surface of the game board 5 at a certain distance from the back surface thereof as shown in FIG. An approaching ball approaching space 8 is formed. Further, as shown in FIG. 2, on the back surface 8 of the mechanism plate 6, a prize ball tank 9 for storing a prize ball on the upper side thereof, a lead-out gutter 10 located below the prize glove tank 9, and a prize ball led from the lead-out gutter 10 to the side part. The prize ball payout device 11 for paying out prizes, and a series of back mechanism parts such as a prize ball processing device 12 for processing prize balls is attached to the lower part of the mechanism plate 6.

In the lower part of the ball-placing space 8 in the mechanism plate 6, a winning ball collecting passage having an open upper surface and a front surface for collecting the winning balls along the lower edge of the window opening 7 and sending them to the winning ball processing device 12. 13 is provided, and the winning ball collecting passage 13 is located in contact with the game board 5 as shown in FIG.

Therefore, the winning ball collecting passage 13 is provided separately from the mechanism plate 6 and a front side wall 14 that comes into contact with the back surface of the game board 5 and a predetermined side wall formed integrally with the mechanism plate 6. The rear side wall 15 which is erected at a distance and the mechanism plate 6
And a bottom wall 16 that is integrally formed with the bottom wall 16 and is inclined downward toward one side end.

In the winning ball collecting passage 13, as shown in FIG. 4, a communication port for communicating the winning ball processing device 12 with the lower end of the bottom wall 16 and discharging the winning ball to the winning ball processing device 12. 17 is provided, and a projecting piece portion 19 through which the winning ball can pass downward from the standing wall portion 18 at the lower end of the flow is provided so as to cover above the communication port 17. The protruding piece portion 19 is inclined downward from the standing wall portion 18, and is formed into a substantially triangular side surface by an upper piece 20 that guides a winning ball flowing on the upper surface thereof to the upper surface of the bottom wall 16 and a lower piece 21 that is continuous with the upper piece 20. There is.

The front side wall 14 is formed in a laterally long shape so as to surround approximately half of the downstream side including the communication port 17 of the winning ball collecting passage 13, and the upstream side edge 14a is formed in a sharp cutting edge shape and has a central portion. It bulges 14b inward. Further, except for the lower edge, an outer peripheral edge portion of the bulged portion 14b is provided with an inclined surface 14c which becomes thinner as it goes to the peripheral edge. Then, the engaging hole 2 as an engaging recess is formed on the downstream side of the front side wall 14.
2 is provided, and a locking piece 23 as a locking portion is provided so as to project substantially at the center of the lower edge.

On the other hand, in the winning ball collecting passage 13, the protruding piece portion 19 is located at a position corresponding to the engaging hole 22 and the locking piece 23.
An engaging piece 24 as an engaging portion projects forward from the inner rear side wall 15, and an engaging hole 25 as an engaging recess is provided below the bottom wall 16. Therefore, the front side wall 14 is pressed from the front side of the mechanism plate 6 to the rear side wall 15 side to engage the engagement piece 24 with the engagement hole 22 as shown in FIG. By locking the locking piece 23 to 25,
The front side wall 14 is easily attached to the mechanism plate 6 as shown in FIG.

In this state, as shown in FIG. 6, the rear side wall 1
5 and the bulging portion 14b of the front side wall 14 are parallel to each other, and an interval is maintained such that a winning ball can pass through. As a result, many winning balls that flow down into the winning ball collecting passage 13 are arranged in a line by the upstream end edge 14a and the inclined surface 14c, and flow down while being aligned between the rear side wall 15 and the bulging portion 14b. It surely flows into the communication port 17.

[0014]

As described above, the mechanism plate of the pachinko machine according to the present invention has the engagement recess and the engagement portion and the engagement portion which are engaged or locked with the front side wall and the mechanism plate. Since the concave portion is provided, the front side wall can be easily attached without using any screw. Further, this simplifies the mounting work and improves workability.
