DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanical plate of a pachinko machine rotatably mounted on the back of a game board.

[0002]

2. Description of the Related Art Conventionally, as a mechanical plate of this kind of pachinko machine, as shown in FIG.
First prize ball collecting passage 1 having a different inclination direction in front of 00
01 and a second winning ball collecting passage 102 formed in a step shape are provided to face each other, and the first winning ball collecting passage 10 is provided.
There is known one in which the winning balls collected in the first winning ball and the winning balls collected in the second winning ball collecting passage 102 are merged and guided to the exit 103 of the first winning ball collecting passage 101.

However, in the prior art, the winning balls collected in the first winning ball collecting passage 101 and the second winning ball collecting passage 1
There is a problem in that the winning balls collected in 02 hit each other near the exit portion 103 and are clogged, so that the winning balls do not flow.

In order to solve such a problem, the present applicant has extended the upstream passage portion 102a of the second winning ball collecting passage 102 which is already formed in a step shape as shown in FIG. The winning balls 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 the ball clogging near the exit portion 103 of the first winning ball collecting passage 101 is prevented. A mechanism plate for a pachinko machine has been proposed to prevent occurrence of such a phenomenon (Japanese Utility Model Laid-Open No. 3-33).
No. 78).

[0005]

However, in the prior application, if many prize balls are retained in the first prize ball collecting passage 101 and the second prize ball passage 102 by a later experiment, it may be shown in some cases. As shown in FIG. 6, it was found that a ball clogging state occurred at the junction. An object of the present invention is to provide a mechanical plate of a pachinko machine that can reliably prevent such a phenomenon that a winning ball is clogged.

[0006]

In order to achieve the above object, a mechanical plate of a pachinko machine according to the present invention comprises a first plate having a different inclination direction on a front surface of a plate portion of the mechanical plate opposed to a back surface of the game board.
The prize ball collecting passage and the second prize ball collecting passage are provided to face each other, and the prize balls collected in the first prize ball collecting passage and the prize balls collected in the second prize ball collecting passage are joined. The first winning ball collecting passage is guided to an exit portion of the first winning ball collecting passage, and the second winning ball collecting passage is connected to the upstream passage portion and the downstream side by a step portion having a height substantially equal to or larger than the diameter of the winning ball. A passage portion is provided in a stepped manner, and an eaves piece is provided at the inclined end of the upstream passage portion so as to extend above the downstream passage portion, and the eaves piece is provided below the eaves piece with the downstream passage portion. Are formed so as to form a gap in which the winning balls can move.

[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 eaves. The operation of moving to the upstream side or moving to the downstream side according to the change of the ball pressure due to the presence of the gap is repeated. For this reason, since the ball collapse phenomenon always occurs at the converging position of the winning ball in the first winning ball collecting passage and the winning ball in the second winning ball collecting passage, the ball is not clogged, and the winning ball exits. It can be guided smoothly to the section.

[0008]

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. A winning ball falling space is formed at a predetermined interval on the front side of the plate-shaped portion 3a opposite to the back of the game board 2 of the mechanical plate 3, and a first winning ball set having a different inclination direction is formed below the space. The passage 4 and a second winning ball collecting passage 5 which is a main part of the present embodiment are formed to face each other. An exit portion 7 for guiding 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, a ball tank 8 for storing pachinko balls supplied from a supply mechanism (not shown) is provided on the back surface of the mechanism plate 3.
And a guiding gutter 9 for aligning and flowing 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 for winning balls. Below the dispensing device 10, a discharge passage 11 and a ball removing passage 12 for guiding the discharged pachinko balls to a ball tray (not shown) on the front surface of the front frame 1 are provided in a branched manner. .

In this embodiment, the second winning ball collecting passage 5 is formed separately from the mechanical plate 3 by the passage member 51.
As shown in FIG. 2, the passage member 51 is made to correspond to the upper part of the exit portion 7 of the first winning ball collecting passage 4 and is screwed to the mechanism plate 3 with screws 13 to be integrated with the mechanism plate 3. Structure.

As shown in FIG. 3, the passage member 51 has a side wall 52 also serving as a mounting plate for mounting to the mechanism plate 3, and a right-angled step 53 is formed inside the side wall 52 to form an upstream side passage portion 54. The downstream passage 55 is provided in a stepped manner.

The height of the step 53 is at least substantially equal to or slightly larger than the diameter of the winning ball. In addition, an eaves piece 56 that protrudes above the downstream passage 55 is provided at the inclined end of the upstream passage 54 located at the upper end of the step 53,
The eaves 56 form a gap 57 in which the winning balls arranged in the downstream passage 55 can move. In addition, the lower surface of the distal end of the downstream-side passage portion 55 is formed as an inclined surface connected to the triangular guide wall 14 provided in the outlet portion 7.

FIG. 4 is a block diagram showing an embodiment of the present invention constructed as described above.
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 sphere can move from the dashed line position to the solid line position or from the solid line position to the dashed line position due to the presence of the gap 57 formed by the eaves 56 in accordance with the change in the ball pressure. At the confluence of the passage 4 and the second prize ball collecting passage 5, the prize balls that collide with each other are collapsing and head toward the exit portion 7, so that the ball clogging phenomenon does not occur and the exit of the prize ball does not occur. The movement to the part 7 is performed smoothly.

[0014]

As is apparent from the above description, the mechanical plate of the pachinko machine according to the present invention is provided with a second winning ball set provided opposite to the first winning ball collecting passage having an exit portion. The passage is constituted by providing an upstream passage portion and a downstream passage portion in a stepped manner by a right-angled step portion, and an eave piece extending over the downstream passage portion is provided at an inclined end of the upstream passage portion, and the eaves are provided. The piece forms a gap in which the prize balls arranged in the downstream passage can move, and the movement of the prize ball by the gap causes the prize ball in the first prize ball collective path and the prize ball in the second prize ball collective path. Since the ball collapse phenomenon always occurs at the position where the ball meets the ball, clogging of the ball does not occur, and the winning ball can be smoothly guided to the exit.
