Description

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 game machine provided with various back mechanisms such as a ball tank and a prize ball payout device.

[0002]

2. Description of the Related Art Conventionally, a ball feeder and a lower storage tray are provided on the front of a front frame of a pachinko game machine as is well known, and a game board can be attached to and detached from the back of the front frame via a game board mounting frame. And a mechanical plate made of synthetic resin is provided on the back surface of the game board. A ball tank and a prize ball dispensing device are provided on the rear side of the mechanism plate, and further, below the prize ball dispensing device, a discharge passage for guiding the dispensed prize balls to the hit ball supply tray and overflow from the hit ball supply tray. A surplus ball passage for guiding the surplus spheres to the lower ball tray, a ball removal passage for removing the pachinko balls in the ball tank, and the like are provided.

In the meantime, in the case of a pachinko game machine, which is generally called a normal machine, the prize ball payout device only has a function of paying out a predetermined number of prize balls to a hit ball supply plate based on a winning ball detection signal. However, in recent years, with the advent of a card-compatible pachinko gaming machine called a so-called CR machine, it has become possible to pay out a lending ball in addition to the prize ball payout function.

That is, in the case of the above-described card-compatible pachinko gaming machine, a card device is adjacent to one side thereof, and a prepaid card in which amount information is recorded in advance is inserted into a card slot and a ball lending switch is provided. By operating a button, a predetermined number of lending balls are paid out to the hit ball supply tray from the prize ball payout device. Specifically, in this card-compatible pachinko gaming machine, when a winning ball detection signal is transmitted, the prize ball payout device is operated in accordance with a command signal from the ball payout control circuit, and the ball counting sensor outputs, for example, 15 minutes.
Upon receipt of the time pulse signal, the operation of the prize ball payout device is stopped, whereby 15 prize balls are paid out, and when there is a ball lending request signal from the card device, according to a command signal from the ball payout control circuit. When the prize ball dispensing device is operated and receives a pulse signal, for example, 25 times from the ball counting sensor, the prize ball dispensing device is stopped so that 25 rental balls are dispensed.

[0005]

However, in the case of a card-compatible pachinko gaming machine, as described above, in the case of a prize ball and in the case of a lending ball, the pachinko ball is provided by a pulse signal obtained from the same ball counting sensor. Therefore, the following problem may occur. That is, in general, pachinko gaming machines have been inspected for counting the number of prize balls and the like by automatically launching a hit ball for a long time at the time of factory shipment or during use, and so on. In this case, if the hit ball is lost during the inspection, the ball rental switch button is operated to appropriately supply the hit ball to the hit ball supply tray, but as described above, the same ball count is used for both the prize ball and the hit ball If the pachinko ball is counted by the pulse signal obtained from the ball sensor, even if the pulse signal obtained from the ball counting sensor is counted by an instrument such as a digital counter, the counted value is based on a prize. There is a problem that the characteristics of the pachinko gaming machine cannot be measured accurately because the two cannot be distinguished from each other due to the request signal for the ball-lending.

[0006] Such a problem is caused, for example, in that a normal machine and a mechanical board of a card-compatible pachinko gaming machine are separately formed, and in the case of a card-compatible pachinko gaming machine, a lending ball and a prize ball are formed. It seems that the problem can be easily solved by making each of them detected by a separate ball counting sensor. However, separately forming the normal machine and the mechanism board of the card-compatible pachinko gaming machine as described above has a problem that mold costs are increased, manufacturing costs are increased, and inventory management is not easy. .

Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a general-purpose pachinko gaming machine called a normal machine or a card-compatible pachinko gaming machine. It is an object of the present invention to provide a mechanism plate of a pachinko gaming machine which can easily cope with the problem.

[0008]

In a mechanical board of a pachinko gaming machine provided with a prize ball payout device for paying out a predetermined number of prize balls to a hit ball supply tray, a ball lending path is provided in the mechanism plate, and a ball lending request signal is provided in the ball lending path. Thus, a ball-lending device for paying out a predetermined number of ball-lending balls to a hitting ball supply tray is detachably attached.

[0009] When a ball rental payout device is attached to the mechanical plate as a mechanical plate of a card-compatible pachinko gaming machine,
In order to be able to supply the ball lending to the ball lending dispensing device effectively, it is preferable to provide a branching portion in the guide passage and to connect the branching portion to the ball lending passage.

When the ball rental device is removed from the mechanism plate and used as a mechanism plate of an ordinary machine, the branch portion may be closed by a ball stopper.

Further, a ball passage for lending a ball may be provided in the guide passage so that the ball passage for lending a ball and the passage for lending a ball may be communicated with each other. Then, when the ball lending dispensing device is removed from the mechanism plate, a spacer member may be fitted into the ball lending ball passage to close the ball lending ball passage.

[0012] With this configuration, the mechanism board for a card-compatible type pachinko gaming machine can be easily changed by attaching the ball rental payout apparatus to the mechanism board for a normal machine provided with the prize ball payout apparatus. Becomes For this reason, it is not necessary to separately manufacture a mechanism plate for a normal machine and a card-compatible type, and the manufacturing cost of the mechanism plate can be reduced.
