2. Description of the Related Art Conventionally, as a mechanical plate of a pachinko machine of this type, a plate-like portion 1 facing a back surface of a game board as shown in FIG.
No. 1 first winning ball collecting passage 1 with different tilt directions
01 and a second winning ball collecting passage 102 formed in a stepped shape are provided so as to face each other, and the first winning ball collecting passage 10 is provided.
It is known that the winning balls to be collected in 1 and the winning balls to be collected in the second winning ball collecting passage 102 are led to the outlet portion 103 of the first winning ball collecting passage 101 while being joined.

However, in the conventional case, the winning balls collected in the first winning ball collecting passage 101 and the second winning ball collecting passage 1 are collected.
There is a problem that the winning balls collected in No. 02 collide with each other near the exit portion 103 and become a ball jam state and the winning balls do not flow.

Therefore, in order to solve such a problem, the present applicant extends the upstream passage portion 102a of the second winning ball collecting passage 102 which is already stepwise formed as shown in FIG. The winning balls to be collected in the second winning ball collecting passage 102 are guided to near the center of the first winning ball collecting passage 101, so that there is no ball clogging near the outlet portion 103 of the first winning ball collecting passage 101. We have proposed a mechanism board for a pachinko machine that is designed to prevent its occurrence (Actual Kaihei 3-33).
Japanese Patent No. 78).

[0005]

However, in the prior application, if a large number of winning balls are retained in the first winning ball collecting passage 101 and the second winning ball passage 102 in the later experiment, in some cases, As shown in Fig. 6, it was found that a ball clogging occurred at the confluence. An object of the present invention is to obtain a mechanism plate of a pachinko machine that can reliably prevent such a ball clogging phenomenon of winning balls.

[0006]

In order to achieve the above object, the mechanism plate of the pachinko machine of the present invention is a first winning ball set in which the front surface of the plate-like portion facing the back surface of the game board has different inclination directions. The passage and the second winning ball collecting passage are formed to face each other, and the winning balls collected in the first winning ball collecting passage and the winning balls collecting in the second winning ball collecting passage are combined to form a first passage. Of the winning ball collecting passage, and the second winning ball collecting passage is provided with a step portion having a right angle so that the upstream passage portion and the downstream passage portion are provided in a stepped shape. The height of the portion is set to be at least about the same as or larger than the diameter of the winning ball, and an eave piece protruding above the downstream passage portion is provided at the end of the slope of the upstream passage portion, and the eave piece is formed by the eave piece. To form a gap below which the prize balls lined up in the downstream passage can move. One in which the.

[0007]

When a large number of winning balls are retained in the first winning ball collecting passage and the second winning ball collecting passage, the winning balls arranged in the downstream passage portion of the second winning ball collecting passage are formed by the eaves. Due to the existence of the gap, the operation of moving to the upstream side or to the downstream side according to the change of the ball pressure is repeated. For this reason, a ball collapse phenomenon always occurs at the confluence of the winning balls of the first winning ball collecting passage and the winning balls of the second winning ball collecting passage. Can be smoothly guided to the section.

Embodiments of 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 front frame of a pachinko machine, 2
Is a game board detachably mounted on the back surface of the front frame 1 via a mounting frame, and 3 is a synthetic resin mechanism plate rotatably mounted on the back surface of the game board 2. On the front surface side of the plate-like portion 3a of the mechanism plate 3 which is opposite to the back surface of the game board 2, a winning ball dropping space is formed with a constant interval, and a first winning ball set having different tilt directions is formed below the winning ball dropping space. The passage 4 and the second winning ball collecting passage 5, which is an essential part of this embodiment, are formed so as to face each other. Then, the outlet portion 7 that guides the winning balls one by one to the winning ball discharge processing device 6 at the inclined end of the first winning ball collecting passage 4.
Are formed.

On the other hand, on the back surface of the mechanism plate 3, a ball tank 8 for storing pachinko balls replenished by a replenishing mechanism (not shown).
A guide gutter 9 for aligning and dropping down the pachinko balls in the ball tank 8 and a payout device 10 for paying out a predetermined number of pachinko balls as prize balls to the winning balls are provided. Further, below the payout device 10, a discharge passage 11 and a ball removal passage 12 for guiding the paid out pachinko balls to a ball tray (not shown) on the front surface of the front frame 1 are provided in a branched manner. .

However, in this embodiment, the passage member 51 in which the second winning ball collecting passage 5 is formed separately from the mechanism plate 3
2, the passage member 51 is made to correspond to the upper side of the outlet portion 7 of the first winning ball collecting passage 4 as shown in FIG. 2, and is screwed to the mechanism plate 3 with the screw 13 to be integrated with the mechanism plate 3. It has a structured structure.

As shown in FIG. 3, the passage member 51 has a side wall 52 which also serves as a mounting plate to be attached to the mechanism plate 3. Inside the side wall 52, a step portion 53 at a right angle forms an upstream side passage portion 54. The downstream passage portion 55 and the downstream passage portion 55 are provided stepwise.

The height of the step portion 53 is selected to be at least approximately the same as or slightly larger than the diameter of the winning ball. Further, an eaves piece 56 extending above the downstream passage portion 55 is provided at the end of the slope of the upstream passage portion 54 located at the upper end of the step portion 53.
The eaves piece 56 forms a gap 57 in which the winning balls arranged in the downstream passage 55 can move. The lower surface of the distal end of the downstream passage 55 is formed as an inclined surface continuous with the triangular guide wall 14 provided in the outlet 7.

The embodiment constructed as above is shown in FIG.
As shown by the solid line, when many winning balls are retained in the first winning ball collecting passage 4 and the second winning ball collecting passage 5, they are arranged in the downstream passage portion 55 of the second winning ball collecting passage 5. The winning balls can move from the chain line position to the solid line position or from the solid line position to the chain line position due to the existence of the gap 57 by the eaves piece 56 according to the change of the ball pressure, whereby the first winning ball set. At the merging position of the passage 4 and the second winning ball gathering passage 5, the winning balls colliding with each other are collapsing toward the exit portion 7, so that the ball clogging phenomenon does not occur and the winning ball exits. The movement to the part 7 is smoothly performed.

[0014]

As is apparent from the above description, the mechanism plate of the pachinko machine according to the present invention has a second winning ball collecting path provided opposite to the first winning ball collecting passage having the outlet portion. The passage is configured by providing a step portion of the upstream side passage portion and the downstream side passage portion by a right-angled step portion, and an eave piece that projects to the downstream side passage portion is provided at the sloped end of the upstream side passage portion, and the eaves The piece forms a gap in which the prize balls arranged in the downstream passage portion can move, and the movement of the prize ball through the gap causes the prize balls in the first prize ball collecting passage and the prize balls in the second prize ball collecting passage.
