DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a plurality of ball alignment passages for guiding pachinko balls in a ball tank to a plurality of ball dispensing devices.

[0002]

2. Description of the Related Art A conventional pachinko machine is provided with a mechanism plate provided with an opening at a substantially central portion thereof, which is provided at the center of a game board and faces a rear portion of a variable display device. A ball tank for storing pachinko balls is mounted above the opening, and a ball guiding gutter is provided in connection with a ball outlet formed at an inclined lower portion of the ball tank. A plurality of ball dispensing devices for discharging a predetermined number of pachinko balls to a discharge gutter are connected to a downstream end of the guiding gutter. Then, each ball payout device is operated by the payout signal to discharge a predetermined number of pachinko balls to the discharge gutter, and accordingly, the pachinko balls flow out of the ball tank to the ball guiding gutter.

For this reason, it is necessary to allow the pachinko balls of the ball tank to flow smoothly into the ball guiding gutter, and the conventional ball tank is formed in a substantially rectangular box shape having an open upper surface, and the bottom wall is inclined to one side. Then, a ball outlet was formed at the lower part of the slope.

Further, in the conventional ball guiding gutter, three ball alignment passages having a width substantially equal to the diameter of the pachinko ball are formed by an alignment wall that gradually increases toward the downstream, and further, a front wall has a step. The auxiliary passage is formed so as to bulge, and the pachinko balls in the auxiliary passage are joined to the ball alignment passage on the downstream side. Two of the three ball alignment passages are connected to the first ball dispensing device, and the remaining one ball alignment passage is connected to the other second ball dispensing device.

[0005]

The above-described conventional pachinko machine has an advantage that the pachinko balls can be efficiently dispensed by a plurality of ball dispensing devices. However, when only the second ball dispensing device is operated, the ball aligning passage 1 is provided. There is a problem that the pachinko balls are clogged by the alignment wall because only the pachinko balls of the striations move.

Further, recent pachinko machines tend to enlarge the variable display device to make the game contents more interesting because the game contents are lost in the mold and lose freshness. The size of the part is limited due to the positional relationship between the ball tank and the ball guiding gutter, and it has been difficult to mount a large-sized variable display device. Also, it is thought that the opening can be easily enlarged by moving the ball guiding gutter upward, but if the ball guiding gutter is moved upward, the height relationship between the ball outlet and the bottom wall of the ball guiding gutter is considered. There has been a problem that ball clogging occurs near the ball outlet due to the ball pressure of the pachinko ball in the ball tank.

Further, when forming the ball guiding gutter, the auxiliary passage complicates the mold and increases the cost, and the ball is clogged when the pachinko balls flowing down the auxiliary passage join the ball alignment passage. There was a point.

Accordingly, the present invention provides a pachinko machine that allows a pachinko ball in a ball tank to smoothly flow out without clogging the ball with a ball guiding gutter, reliably supply the ball to a ball dispensing device, and further ensure a large opening of a mechanism plate. The purpose is to provide a machine.
