Description

  The present invention relates to a gaming machine having a tank rail for aligning and flowing down game balls stored in a prize ball tank and a curve rail for connecting a prize ball payout device, and more particularly, a gaming machine having a novel structure. It relates to pachinko machines.

  Conventionally, an attachment frame for attaching a game board is provided on the back side of the inner frame of the pachinko machine, and a mechanism plate is rotatably attached to the attachment frame. In addition, a prize ball tank for storing a game ball replenished from a replenishment basket disposed above the pachinko machine is fixed to the upper part of the mechanism plate, and a prize ball is placed below the prize ball tank. A tank rail is provided for allowing the game balls stored in the tank to flow down while being aligned. Furthermore, a curved rail is connected to the lower end of the tank rail, and a prize ball is awarded based on the winning of a game ball to various winning openings provided on the game board with respect to the lower end of the curved rail. A prize ball payout device for paying out (game balls) is connected.

  The curve rail connecting the tank rail and the prize ball payout device in this way reduces the pressure (ball pressure) exerted on the game ball that is allowed to flow down in a single line through the ball path provided on the curve rail and the subsequent game ball. Since the ball is guided to the prize ball payout device, generally, the ball passage through which the game ball is allowed to flow down has a curved shape. In many cases, the curved rail is provided with a plurality of ball passages having such a curved shape. Therefore, the curve rail of the conventional structure is generally composed of a plurality of plate members by assembling the partition plates between the outer plate and the back plate in a fixed manner as described in Patent Documents 1 and 2, etc. It has a structure in which a plurality of ball passages are formed between the opposing surfaces.

  However, the conventional curved rails as described in Patent Documents 1 and 2 have a structure in which a plurality of large plates are stacked on top of each other. There was a problem that it was difficult to do.

  Therefore, in order to cope with such a problem, it is also conceivable to form a curve rail by superimposing a plurality of these on a groove groove rail that only meanders and extends in a groove groove cross section.

However, if one tries to construct a curved rail by stacking such concave groove rails that do not have a large plate part as in the conventional structure, the following problems will newly occur, and its practical application will be made. It was difficult.
(B) In the conventional structure, it was possible to freely provide pins or the like for aligning a plurality of members that were superposed on each other on the large plate portion, but the grooved rail overlay structure was adopted. Then, it is difficult to position the overlapping groove rails with each other, and it is difficult to work due to the occurrence of misalignment during mounting. In addition, if a plurality of concave groove rails are overlapped and fixed to each other with their positions shifted, the cross-sectional shape of the ball passage may be deformed, and it may be difficult to achieve smooth circulation of game balls. is there.
(B) In the conventional structure, it was possible to easily form ribs that protrude in the overlapping direction from each other in a large plate part with a size that can be easily seen, but a grooved rail overlapping structure was adopted. Then, since all of the plurality of concave groove rails that are superposed on each other have substantially the same shape, there is a problem that the operator is likely to make a mistake in the superposition order. If the wrong ball assembly is assembled, the target ball passage will not be formed, and even if you notice it in the middle of the work, you will need extra time and effort to remove the assembled groove rail and reassemble it. There was a problem that efficiency was bad because it was necessary.

The ball path for guiding the game ball is formed between the opposing surfaces of the protruding tip surface of the groove and the bottom surface of the concave groove.

  In the pachinko machine structured according to this embodiment, in one of the groove rails that are directly overlapped, the other groove is projected from the both side walls of one groove groove to the other groove rail side. Since there are a plurality of locking projections that are locked to the outer surfaces of the both side walls of the rail, the locking projections provided on one of the groove rails serve as a mark and are directly superimposed. The groove rails are distinguished from each other. As a result, it is possible to alert the operator to the order of stacking the groove grooves and the like, and it is possible to prevent the worker from overlapping a plurality of groove grooves in the wrong order.

  Moreover, in this aspect, since the ditch | groove rail directly piled up by the latching protrusion provided in the both side wall in one ditch | groove rail mutually is positioned, the ditch | groove directly piled up The positioning accuracy between the rails can be improved. Therefore, it is possible to prevent a plurality of concave groove rails from being overlapped in a shifted state, and thereby, a gap or a step at the connection point with the tank rail and the connection point with the prize ball payout device on the curve rail. It is possible to prevent the game ball from flowing from the tank rail to the curve rail and the prize ball payout device.
