Description

[Detailed Description of the Invention] The present invention relates to a control device for a pachinko game machine for controlling the supply of pachinko balls to a prize ball storage tank provided in the pachinko game machine.

Conventionally, a so-called out tray for temporarily storing pachinko balls (out balls) hit into a pachinko game machine has been provided at the lower part of the back side of the pachinko game machine, and at the same time, it has been provided at the upper part of the back side of the pachinko game machine. A return machine is provided that is operated when the remaining amount of pachinko balls in a tank for storing prize balls drops below a certain level, and the pachinko balls in the out tray are returned to the tank in accordance with the operation of the return machine. A reversible pachinko game machine configured to play the game is provided.

However, while such a pachinko game machine has the advantage that the state of change in the number of pachinko balls in the tank can be adjusted to a certain extent and the so-called slump can be easily adjusted, it has the following disadvantages.

(b) Since a reducing machine with a relatively complicated structure is required, the overall structure becomes complicated and the cost increases accordingly.

(b) Since the same pachinko ball circulates within the pachinko game machine for a long time, there are fewer opportunities for the pachinko ball to pass through the cleaning machine, resulting in insufficient cleaning of the pachinko balls.

(c) Since the number of pachinko balls in the out tray cannot be ascertained, the income and expenditure of the pachinko game machine cannot be accurately detected.

The present invention was developed in view of the above circumstances, and its purpose is to eliminate the need for a reduction machine, simplify the overall structure and reduce costs, and to provide sufficient cleaning and cleaning of pachinko balls. Although it is possible to accurately detect the income and expenditure of a pachinko game machine, and also eliminates the need for a return machine, it is possible to detect changes in the number of pachinko balls in the prize ball storage tank of the pachinko game machine. To provide a control device for a pachinko game machine which has the advantage of being able to adjust the slump of the pachinko game machine to a certain extent and making it easy to adjust the slump of the pachinko game machine.

corresponds to

Although FIG. 2 shows a circuit configuration for controlling only one pachinko game machine 1, it is of course possible to actually control a large number of pachinko game machines. Also, although not shown, a safe pitch counter 8b, an out pitch counter 1
A function is provided to total the outputs of 2 and to total the number of safe pitches, the number of out pitches, and the difference thereof for each pachinko game machine 1. Furthermore, the functions of the control circuit 30 in FIG. 2 are actually obtained by a microcomputer.

Next, the operation of the above configuration will be explained. Now, when there are no more pachinko balls in the tank, the first detection switch 3 that detects this turns on, and the pulse signal _S13 is output from the pulse generation circuit 13. Then, the R-S flip-flops 15, 16 are set (the R-S flip-flop 17 is not set), and the R-S flip-flops 15, 16 are set.
A high level signal is output from each of the 16 set output terminals Q. Therefore, the high level signal from the R-S flip-flop 15 initializes the counting contents of the safe ball counter 8b, and the amplifier 2
9 energizes the electromagnetic solenoid 8a to switch the supplementary ball device 8 to the additional ball supply state, and the high level signal from the R-S flip-flop 16 causes the transfer gate 22 to read the reference value from the storage section 21.
Now passes N ₂₁ (400). For this reason,
Pachinko balls start being supplied from the branch pipe 7 into the tank 2, and the safe ball counter 8b initialized as described above starts counting the pachinko balls supplied into the tank 2. In this way, when 400 pachinko balls are supplied into the tank 2 and the count value of the safe ball counter 8b reaches "400", the relationship of N ₂₁ ≦S ₈ , that is, the input terminals A and B of the comparison circuit 23 Since the input of R- exhibits the relationship A≦B, a high level signal is output from the comparator circuit 23 and R-
S flip-flops 15 and 16 are reset,
The output of the set output terminal Q of each R-S flip-flop 15, 16 is inverted to a low level signal. For this reason, the electromagnetic solenoid 8a is cut off and the supply of pachinko balls by the ball supplementary device 8 is stopped.
The transfer gate 22 exhibits a shriveled state, and as a result, when the tank 2 becomes empty, 400 pachinko balls are automatically supplied into the tank 2.

Further, during a pachinko game, the out ball counter 12 successively counts out balls flowing out from the pachinko game machine 1 into the ball pulling path 9, and outputs a numerical signal _S12 indicating the counting contents. When the remaining number of pachinko balls in the tank 2 falls below a certain level as the pachinko game progresses, the second detection switch 4 detects this and turns on, so that the pulse signal S ₁₄ is output from the pulse generation circuit 14. . Then, R-S
Flip-flops 15 and 17 are set (R-
S flip-flop 16 is not set), R
The high level signal from the -S flip-flop 15 causes the safe ball counter 8b to be initialized and the ball complementer 8 to be switched to the additional ball supply state, as described above. Further, the temporary storage circuit 24 which receives the high level signal from the R-S flip-flop 17 at the check terminal C stores the numerical signal _S12 at the time of the rise of the high level signal, and also transmits the high level signal to the gate terminal 22a. The received transfer gate 22 now passes the numerical signal _S24 from the temporary storage circuit 24. Further, a short time after this point, the delay circuit 26 outputs the delayed signal.
In order to output _S26 , the counting contents of the out ball counter 12 are initialized by this delayed signal _S26 . Then, as the supply of pachinko balls by the ball supplementary device 8 progresses, the count content of the safe ball counter 8b becomes a numerical signal.
S ₂₈ (i.e., the second detection switch 4
When the number of out pitches reached (the number of pitches out at the time when the switch was turned on), the inputs of the input terminals A and B of the comparator circuit 23 become A≦
Since a high level signal is output from the comparator circuit 23 with the relationship B, the supply of pachinko balls by the ball supplementary device 8 is stopped and the transfer gate 25 is in a sluggish state as described above. In short, every time the number of pachinko balls in the tank 2 falls below a certain level, a number corresponding to the number of out balls in the period from the time of the previous complementary ball to the tank 2 until the second detection switch 4 is turned on. Pachinko balls are automatically supplied into the tank 2 from the ball supplementary device 8.

On the other hand, if the number of pachinko balls in the tank 2 falls below a certain level and the number of out balls reaches 500 before the second detection switch 4 is turned on, in other words, the number of out balls in the out ball counter 12 When the count value reaches "500" corresponding to the limit value N ₂₇ stored in the storage unit 27, the relation N ₂₇ ≦ S ₁₂ is established, and the clear signal S ₂₈ is output from the comparator circuit 28. Therefore, the counting contents of the out ball counter 12 are initialized. Therefore, the number of pachinko balls exceeding the limit value _N27 corresponding to the capacity of the tank 2 will not be supplied into the tank 2.

According to the present embodiment described above, when the remaining amount of pachinko balls in the tank 2 falls below a certain level, a number of pachinko balls corresponding to the number of out balls at that time are supplied into the tank 2. Therefore, like the conventional reduction type pachinko game machine, the changing state of the pachinko balls in the tank 2 can be adjusted to some extent, making it easier to adjust the so-called slump of the pachinko game machine 1. In this case, since a conventional reduction machine is not required, there is no risk that the overall structure will become complicated and the cost will increase.
Moreover, the out balls of the pachinko game machine 1 are not returned to the tank 2, but are collected in the ball pulling passage 9 and guided to a cleaning machine (not shown), so that the out balls are not returned to the tank 2, but are guided to a cleaning machine (not shown). There is no risk of insufficient cleaning. Furthermore, since there is no need for a lower tray for temporarily storing out balls as in the past, the flow of pachinko balls in the pachinko game machine 1 can be accurately grasped, and the income and expenditure of the pachinko game machine 1 can be accurately detected. be able to.

According to the present invention, as is clear from the above explanation, it is possible to eliminate the need for a reduction machine, simplify the overall structure, and reduce costs accordingly,
It is possible to sufficiently clean the pachinko balls and accurately detect the income and expenditure of the pachinko game machine, and while this configuration eliminates the need for a return machine, It is possible to provide a control device for a pachinko game machine which has the advantage of being able to adjust the state of change in the number of pachinko balls to a certain extent and making it easy to adjust the so-called slump of the pachinko game machine.
