Description

[Detailed Description of the Invention] The present invention provides an advantageous state for the customer when a game ball flicked into the game board satisfies a predetermined value condition, for example, by opening a variable winning ball device, which is advantageous for the customer. In a pinball game machine designed to increase the frequency of winning balls from the opening, even if the fraud that is often committed by making it impossible to detect the number of winning balls ends up being a waste of effort. This invention relates to an anti-fraud device for restricting winning balls in a pinball game machine, which allows compliance with the restrictions on winning balls stipulated in the Amusement Business Control Act.

The value conditions that the game ball must satisfy in order to play the relatively large lid of the variable prize ball device include, for example, a game ball that enters a specific prize [1] that opens for a certain period of time, a variable prize that is closed, etc. By entering a ball into a specific section of the ball device, the opening time can be extended, and by first entering a specific winning hole, a variable display using a rotating drum or LED variable display can be displayed in different ways. , the change in the display on the variable display is stopped after a certain period of time has elapsed or a stop signal is received from the stop switch f-. Open!
It is well known that there are various types of -b, such as those that determine the length of the opening time or the length of the opening time (see Japanese Unexamined Patent Publication No. 57-183-1835').

If you listen to the relatively crowded lid of the variable winning ball device, the winning state or the frequency of winning balls will improve significantly, so if you can get unlimited winning balls during the opening time, you will not be overly motivated to win. Therefore, the Amusement Business Control Act stipulates a limit value, and it is necessary to reach this limit value.
At one point, even if the opening time is still within a certain level, the lid is closed so that no one can enter unrestrictedly. From the equipment's point of view, this means A detection switch for detecting the number of balls and a J-runter that counts the opening/closing operation of the detection switch is designed. was added.

On the contrary, in order to attract more customers, some game arcades have completely ignored the above-mentioned limit value and committed fraud such as preventing the lid of the variable winning ball device from closing even after the number of winning balls reaches the limit value. I was in awe. The reason for this is not only the conscience of the store, but also the fact that the fraud mentioned above can be done extremely easily in conventional gaming machines (in some cases, the fraud described above can be easily manipulated, and even if such fraud is carried out, there is no problem for the gaming machine to leak it). It can be said that the fact that it was given to them had something to do with it.

In order to make it easier to understand the present invention, we will first clarify how the control circuit of the conventional variable prize winning ball device was implemented as an IM, and how fraud could easily occur. As a conventionally known pinball game machine, the front view is shown in Fig. 1.
Figure 2 shows the state of the back side of the board, and Figure 3 shows the control circuit for the winning balls. As is clear from the figure, this control circuit is controlled by an input circuit consisting of a pull-up resistor R1 and a Schmitt trigger 4, and an opening/closing operation of a detection switch S1 that detects when a ball enters a specific winning hole 1. The D-type flip-flop 5 is driven as a set, and the +
It is the timer 6 that starts the ``2'' type frits button 15, and the attacker solenoid 8 for driving the variable winning ``ball device 2''. It has a driver 7, a detection switch 82 for detecting the number of pitches entered into the variable winning ball system w2, a counter 9 for counting the opening/closing operation, a counter 9 for counting opening/closing operations, and a logical sum gate G1, and a time knob for the timer O. The signal and the count-up signal of the counter 9 are respectively sent to the reset terminal of the flip-flop 5 via the logical sum gate G1. ) It is becoming more and more popular.

When the ball that was just bounced into the game board enters the input port 1 and the detection switch S1 opens and closes, the D-type flip-flop 5 is set and the attacker solenoid 8 is driven via the driver 7. , Accordingly, M3 of the variable winning ball device 2 opens.

At the same time, the timer 6 is started and starts counting a certain period of time. When a certain period of time has elapsed, the timer 2 knob signal issued from the timer 6 resets the D-type flip knob 5 via the OR gate G1, thereby closing the lid 3 of the variable winning ball device 2. On the other hand, the number of incoming /j balls while the lid 3 of the variable winning ball device 2 is listening is detected by the number of opening/closing operations of the detection switch S2, and the counter 9 records J and hl. When the 81 value of the counter 9 reaches the limit value, the count-up signal is passed through the OR group 1-01 and rehits the D-type flip-flop [1. Flipf 1 Kotpu 5 will be replayed, so at that point the drive of the attacker solenoid 8 will be released and the variable prize ball game @
2 Wi6 will close. However, with this configuration,
For example, in FIG. 3, the wiring at the location indicated by the symbol Δ is cut 11i.
By doing so, the detection operation of the detection switch S2 for detecting the number of balls entering the variable prize winning ball device 2 is killed, thereby stopping the number operation of the counter 9, and as long as the lid 3 is open. If you can easily win as many prizes as you like
ll] I was able to do it, and then I cut it again as above and then -b,
This is because the operation of the ffl number has stopped and there is no problem with the other gaming machines fj12.

As stated above, the inventors of the present invention have been conducting extensive research into ways to overcome the drawbacks of the conventional technology.

As a result, while playing with a normal gaming machine, when the town weirdo award ball device is open, it is actually extremely rare that there is no winning ball within a certain period of time. We focused on - When a fraudulent manipulation like the one described in 2.2 is made, the fraud can be detected by making the game appear as if there were no winning balls within a certain period of time (11). The present invention has finally been completed based on these findings.

That is, the present invention provides a variable prize winning ball device with a frontage when a game ball that is flung into the game board satisfies a predetermined value condition. detecting the presence or absence of a winning ball from the opening 1:1 within a certain time period during the opening time of the variable winning ball device; For detecting abnormality when there is no tit ball in the certain period of time]]
In this way, this device is designed to prevent fraud regarding the winning ball limit of a pinball game machine.

In order to detect whether the winning ball is 1 or 1, there are known means such as normally open or normally closed contact switches, non-contact proximity switches, such as those using inductance, photoelectric conversion elements, and magnetic sensing elements. You can choose as appropriate. The abnormality detection output described above can be used to close the variable winning ball device, to disable the game machine itself, to disable the operation of the electric ball driving unit, or to change the power supply circuit of the game board. It goes without saying that it is possible to turn off the power, disable the game control of the game board, and even activate the alarm device of the central control device provided remotely, as appropriate.

The present invention is illustrated in the drawings and will be described by way of embodiments as follows.

Comparing FIG. 4, which shows the first embodiment of the present invention, with FIG. 3, which shows the conventional example, it can be seen that they are the same except for the following three points. That is, the detection switch S2 that detects the number of winning balls is a normally open switch, and the contact momentarily becomes closed every time a winning ball passes, but otherwise (...
L is normally closed, normally closed switch 1 is detected,
A time determination circuit 10 for determining the duration of the contact output state of the switch S2 is provided in stage IJ, and when the duration 11fi exceeds a predetermined value, the determination circuit 10
The output of the above is given to the reset terminal of the above-mentioned flip knob 5 via the logical sums G1 to G1.

According to the part marked A in Fig. 3, ? in Fig. 4? If No. 1 Δ is disconnected, the detection switch S2, which is a normally closed switch, will continue to emit the same contact output state as when it does not detect a winning ball. Become. In this way, when the time between b aid in the contact output state exceeds a predetermined value, the time judgment circuit 10 operates and forcibly resets the D-type flip-flop 5, thereby cutting off the power to the attacker solenoid 8, and thus the variable winning ball device. Move to close the lid 3 of 2. Unless this fraud is committed, the winning ball will operate the detection switch S2 several times within the predetermined time, so the time determination circuit 100
No judgment output is generated. Therefore, the lid 3 of the variable prize winning ball device 2 is controlled either by a fixed time period or by a limited number of balls, and the provisions of the Amusement Business Control Law are complied with. Note that the alarm device 1 operates based on the judgment output from the time judgment circuit 10.
Adding 1 is convenient because it not only informs of fraud, but also malfunctions around the detection switch S2 and defective electrical contacts. The above judgment output can be used to forcibly stop the operation of the electric ball driving unit, or to cut off the power supply circuit of the game board, or to disable the game control, or to prevent concentration]! I! In other words, the game (

The time judgment circuit 10 is composed of a timer that sets the time reference by 1q, and a circuit that compares the duration of 51 o'clock and the above duration. be done. FIG. 5 shows an example of a simple configuration using a type of delay circuit consisting of a resistor R1 and a long answer C1. In the figure, the diode A-D1 is used to obtain a delay operation only at the rising edge of the input signal, and the level detector ioa is connected to the resistor Rt,
This is the 1st, cth one that discriminates the delayed output of t.

The present invention is disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 57-183883. (C) is satisfied, and the next valence condition is satisfied, which is when all three indications by the rotating drum are completed. A pinball game (applicable to many things. No. 6)
The figure shows an example of the conventional I+] control circuit for this type of game, and
In Fig. 7, the present invention is applied to the circuit of Fig. 6! ζ Examples are shown for each.

In FIG. 7, the ties 11 to 1 at points A to 1 are shown separately for cases in which there is no count signal within T2 between l+1 and cases in which there is, so the former and the latter are shown separately. The difference lies in whether or not a pulse is generated at the two points connected to the winning ball detection switch S2 and the pulse generator 13.

D, point C of Ha remains unchanged, and point C of Ha is AND goo 1
12 and is also connected to the delay circuit 24, the output side of the delay circuit 24 is the same in that it generates a pulse after the delay time. This pulse is connected to the reset terminal of the flip-flop 25, which is connected via the two points mentioned above. The output of the flip-flop 25 is connected to the other input terminal of the AND gate 12 via a point E. Therefore, regarding point (e) above, the output is seen only when there is a J runt signal, but the 81 power is seen until the signal from the delay circuit ii32/l is applied to the reset terminal of the flip-flop 25. It is. AND game 1 to 12
The output *&1f is taken to the terminal 1 of the flip-flop 15, and in this example, when no τχ ball enters within time T2 at tIX, the electric ball driving unit is disabled 9). d:i, AND pulse oscillator 26 1 to 23

I will explain 1i1. First, within [time]-2, the detection switch S
This is the case where there is no count signal from 2, but 11) between T
The outputs of the timer circuits for 1 and T2 are sent to the OR gate 17 via inverters 16 and 16, and the outputs of OR gates 1 to 17 are connected to the reset contact of the flip-flop 18, so the output is output for the same time as the output of the timer circuit 14, as shown in the waveform f. Utilizing this, it is possible to release the drive of the attacker solenoid 8 after the time T2 has elapsed. On the contrary, within T2 between IS (
When the count signal from the J detection switch S2 has a waveform like C, the ΔAND gate 20 which inputs the count signal from the timer circuit 14 outputs zero, which is the same as the count signal like I. The flip-flop 21, which receives this output at its set terminal and the inverted output of the timer circuit 14a at its reset terminal, outputs an output for the same time as the output of the timer circuit i4a, as indicated by G. The OR gate 19 receives the output of the output for the same time as the output of the timer circuit 14a, as indicated by H. As a result, the actuator solenoid 8 outputs the output for the time T1.
Continue medium drive. However, when the number of winning balls reaches the limit value by the counter 9, the flip-flop 22
At that point, the drive of the actuator solenoid 8 is stopped by not outputting the output from the AND gate 23. The operation of the pulse oscillator 26 is the same as shown in Fig. 7).

As is clear from the above explanation, the present invention uses the following criteria as a criterion for determining whether or not there is fraud regarding the winning ball restriction.
By relying on the novel and ingenious characteristic of determining whether or not there were any winning balls at all during the variable winning ball device [fixed time within 1 hour T1] 2, the prevention device C can be relatively simple. , and also ensuring compliance with the provisions stipulated in the Entertainment Business Control Act.
