DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine configured so that the number of prize balls cannot be changed.

[0002]

2. Description of the Related Art Pachinko gaming machines, which have become popular entertainments, must not excessively stimulate gambling, and as is well known, the mechanism is examined by the authorities of each model and approved for use. . It must not be modified and used for business. However, in the conventional pachinko gaming machine, since several signal lines for transmitting the prize ball control signal from the main board to the control board are wired in parallel, the game ball won by replacing the signal lines. It was possible to make modifications to increase or decrease the number of prize balls paid out in such cases. For this reason, there has been a problem that illegal remodeling can be easily performed by changing signal lines.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent unauthorized alteration from being easily performed by such a change of signal lines.

[0004]

SUMMARY OF THE INVENTION To this end, the present invention provides a main board provided with a game control circuit for detecting a winning of a game ball and outputting a predetermined prize ball control signal; In a pachinko game machine having a control panel for operating a prize ball payout device in accordance with the prize ball control signal and paying out a predetermined number of prize balls, a plurality of control panels are transmitted from the main board to the control panel via a signal line transmitting a prize ball control signal. The control panel is provided with a signal matching section for determining whether the matching signal is different or not.

The large winning opening 9 that opens and closes is a normal winning opening.

[0006] Reference numeral 10 denotes a winning ball collecting gutter provided on the back side of the pachinko gaming machine. Reference numeral 12 denotes a main board composed of a printed circuit board removably set in a transparent plastic case 11. A control panel 13 also includes a printed circuit board provided in a small transparent plastic case 14 provided on the back side of the pachinko game machine. Reference numeral 15 denotes a prize ball storage tank, 16 denotes a prize ball payout device, 17 denotes a prize ball discharge gutter, and 18 denotes a hit ball launching device.

FIG. 3 shows a block diagram of the main board 12 and the control panel 13. A game control circuit 20 for controlling a game mode is incorporated in the main board 12, and a prize ball control signal output section 21 is provided. 22
Is a secondary winning ball detection switch for detecting a winning ball that has entered the starting winning opening 6; 23 is the variable winning device 7;
And a main prize ball detection switch for detecting a prize ball entering the normal prize opening 9. The operation signals of the sub prize ball detection switch 22 and the main prize ball detection switch 23 are transmitted to the game control circuit 20.
And the signal is processed.

Further, the control panel 13 is provided with a prize ball control signal input section 30 and a prize ball control signal output section 21
Is received by the prize ball control signal input section 30 via the signal lines 24 to 29. That is, the award ball setting signals A to D are transmitted from the award ball control signal output unit 21 to the award ball control signal input unit 30 via the four parallel signal lines 24 to 27, and the two signal lines 28 and 2
9, an auxiliary prize ball payout command signal E and a main prize ball payout command signal F are transmitted. Further, the control panel 13
Is provided with a signal collating unit 31 and a prize ball payout signal output unit 32.

[0009]

[Table 1]

The prize ball setting signals A to D are used to transmit the number of sub prize balls and the number of main prize balls of the game control circuit 20 from the main board 12 to the control panel 13, and as shown in Table 1, the respective prize balls are set. The setting signals A to D are composed of a collation signal portion, a number-of-prize-winning-ball setting signal, and a number-of-main-prize-ball setting signal. The prize ball setting signal A is for setting one as the number of prize balls, and the signal “0111”
Is transmitted as a collation signal, "0" is transmitted as a sub prize ball number setting signal, and "1" is transmitted as a main prize ball number setting signal. The prize ball setting signal B is to set two as the number of prize balls. The signal “1011” is transmitted as a collation signal. 1 ". Also, a prize ball setting signal C
Indicates that four prize balls are set, and the signal "110"
After “1” is transmitted as the collation signal, “1” is transmitted as the number-of-sub prize balls setting signal, and “1” is transmitted as the number-of-prize-prize balls setting signal. The prize ball setting signal D is for setting the number of prize balls to eight, and after the signal “1110” is transmitted as a verification signal,
"0" as the prizes cell count setting signal, "1" is transmitted as the main prize ball number setting signal. Therefore, in this case, the number of extra prize balls is 6
It is transmitted to the control panel 13 so that the number of the main prize balls becomes 15. The prize ball setting signals A to D are repeatedly transmitted at a period a as shown in FIG. Then, the signal matching unit 31 determines whether or not the matching signal of each of the prize ball setting signals A to D matches the matching signal set in the signal matching unit 31 in advance. The payout signal output unit 32 is operated.

[0011]

[Table 2]

The auxiliary prize ball payout command signal E is sent to a signal line 28 when the auxiliary prize ball detection switch 22 detects a prize ball.
Is transmitted from the prize-ball control signal output unit 21 to the prize-ball control signal input unit 30 via the reference signal unit consisting of the signal “0101” as shown in Table 2 and FIG. "1" is transmitted as the command unit. The main prize ball payout command signal F is output to the prize ball control signal output unit 2 via a signal line 29 when a prize ball is detected by the main prize ball detection switch 23.
1 is transmitted to the prize ball control signal input unit 30. After transmitting the signal "1010" as a collation signal, "1" is transmitted as a main prize ball payout command. These collation signals are similarly discriminated by the signal collation unit 31, and only when the collation signals match, the award ball payout signal output unit 32 gives the award ball payout command to the award ball payout device 16 and the main award ball payout command. A payout command is output.

Therefore, in the combination of the main board 12 and the control panel 13, the signal lines 24 to 27 of the prize ball setting signal are temporarily replaced, or the signal line 28 of the auxiliary prize ball payout command signal and the main prize ball payout command Signal line 29 for signal
Is broken or the wire is broken, a normal verification signal is not transmitted, such a fraud or abnormal occurrence is detected by the signal verification unit 31, and the prize ball is not paid out. It is impossible to intentionally increase or decrease the number.

When the main board 12 is replaced with another one, the replaced main board 12 is also shown in Table 1.
If the same collation signal is output, the number of sub prize balls and the number of main prize balls can be exchanged for an authorized product set to a unique one according to the game mode of the main board 12. is there.

Table 1 and Table 2 show the collation signals.
It is needless to say that the collation signal is not limited to those shown in Tables 1 and 2, for example, as shown in Tables 3 and 4 and FIGS. Only the main board that outputs a specific verification signal can be attached to this pachinko gaming machine, and it is also possible to prevent use in other combinations. For this reason,
By exchanging the main circuit board with another model not permitted, it is also possible to prevent fraudulent activities such as tailoring the game to a higher gambling property.
