Abstract

PROBLEM TO BE SOLVED: To prevent the tampering by providing a game machine with a picture display device, a game ball detector, a judgement counter and a numeral display device, and starting a special game state when a value of the judgement counter reaches a specific value to provide a pulse signal unoutput state where a pulse signal is not output from a display counter to the numeral display device. SOLUTION: When a game ball enters an ordinary electric generator and passes through a specific area, and a detecting signal is output from a detector, whether a big win or not is judged on the basis of a value of a judgement counter. On this occasion, whether a value of the display data D is a specific value, for example, 15 or not is judged, 1 is added to a display counter C when the value is not 15, and the same value is kept when the value is 15. Then the processing for providing the display counter C with the circulating numbers 0-7 is performed. When the display data do not exist, the same value is kept on the display counter C. That is, the adding process by a pseudo counter can be prevented by providing the pulse signal unoutput state, and the tampering can be prevented by making a value of the pseudo counter different from that of the judgement counter.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game control device for selecting a special game state or the like provided in a gaming machine, and to preventing an illegal act by attaching an illegal board to the game control device.

[0002]

2. Description of the Related Art Conventionally, pachinko machines as gaming machines include:
A liquid crystal symbol display, a numeric display (7-segment display), and the like capable of variably displaying a plurality of symbols are arranged substantially at the center of the game area. This gaming machine is configured with a block diagram shown in FIG. 7 (A), which is a method for generating a special gaming state (big hit), is initialized at the same time as power-on, and is set to 1 every predetermined time (2 ms). A judgment counter Hc for adding is provided. The determination counter Hc has a value at the time of the falling of the game ball detection signal when the game ball is detected by the game ball detector after passing through the specific area after winning the start winning prize opening installed in the game area. It is determined by

[0003]

On the other hand, FIG. 7 (B)
FIG. 4 is a block diagram in which the gaming machine is provided with fraudulent means;
This is performed through the signal of the terminal (a, b) of the display control device by attaching an illegal board in which pu or rom for storing illegal software is stored. Has already been presented in Japanese Patent Application No. 10-103768. However, in addition to the symbol display, a number display (7-segment display) and the like are arranged in the gaming machine.
There are signals that can be synchronized with the value of c.
Therefore, if the same illegal board as described above is attached to such a signal, at first glance, it seems as if playing a game as usual, and the clerk cannot easily determine whether or not the act is fraudulent. Since the fraudulent board is small, it cannot be easily detected from the back of the gaming machine whether or not the fraudulent board is attached.
Therefore, the present invention provides a gaming machine capable of preventing illegal acts even when such an illegal substrate is attached.

[0004]

A game machine according to a first aspect of the present invention has a symbol display, a game ball detector, a judgment counter, and a number display. When the value of the judgment counter is a specific value, a special game state is set. By generating a pulse signal from the display counter and not outputting a pulse signal to the numeric display, and providing a pulse signal non-output state, even if an illegal board is attached, a counter synchronized with the determination counter cannot be provided, and illegal acts are performed. Can be prevented.
Further, since the gaming machine according to the second aspect performs the non-output state of the pulse signal when there is no display data, it is possible to prevent fraud without affecting the number display.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pachinko machine as a gaming machine is of a well-known type, and is related to the gist of the present invention with reference to a front view shown in FIG. 1 and a control block diagram shown in FIG. Will be described. FIG. 2 is a block diagram in which an illegal board is attached. In a normal gaming machine, terminals C and D of a game ball detector are connected to terminals c and d of a relay board.

At a substantially central portion of the game area 19, a liquid crystal display type symbol display L for performing a variable display game via a plurality of variable symbols is arranged. The image display data E written by the CPU provided in the apparatus is displayed separately on, for example, the symbol display sections L1 to L3 via the display control device, and the symbols "0 to 9, A to F" are displayed.
Are displayed in this order.

On the left and right sides of the symbol display L, ordinary symbol start gates 23a and 23b are provided, and when a game ball passes, an ordinary symbol display 5 attached to a large winning opening 58 described later.
The pattern of 6 (7-segment numeric display) starts to change,
It stops after a lapse of a predetermined time, and a hit occurs when the finalized symbol matches a predetermined symbol, so that the ordinary electric accessory 57 is opened for a predetermined time. Then, when a game ball wins the ordinary electric accessory 57 and passes through a specific area, a game ball detector (not shown) for detecting the winning ball generates a game ball detection signal, which will be described later in detail. It is determined whether or not the special game state described above occurs.

[0008] Further, the CPU includes the ordinary symbol display 56.
In order to control the numbers displayed on the (numerical display), the display data D (memory) in which the value to be displayed is written is connected to the decoder D, and the output of the display counter C (memory) is connected to the decoder C. Are output to each segment Li (i = 1 to 7) via an AND element. These states are shown in the table of FIG. Note that each segment Li in the seven-segment display number display (ordinary symbol display 56) is associated with each other as shown on the right side of FIG.

On the other hand, the terminals (a ', b',
c ′, d ′) are the terminals (a, b,
c and d), the terminals C and D of the game ball detector are connected to C 'and D', and the terminals (e 'and f') of the illegal board are connected to the terminals c and d of the relay board. The software stored in the rom is executed by the cpu to perform fraud.

Next, a fraudulent act when the fraudulent board is attached will be described with reference to a control flow of FIG.
The control flow is executed by an interrupt process every reset time (time during which the entire game software can be executed: 2 ms). In addition, the dishonest person can determine the judgment counter H in this gaming machine.
It is known that c is a circulation number of 0 to 329, and “7 (specific value)” is a special game state (big hit).

When the power is turned on, as shown in FIG. 3A, the judgment counter Hc and the display counter C are initialized, and 15 is written in the display data D (S1, S2).
S2). The state of the display counter C is determined by terminals a, b, c,
d from the display data D (each segment Li
Are all turned off) on the numeric display, and these terminals a,
In any one of b, c, and d, a pulse signal is generated every reset time continuously from when the power is turned on. Therefore, in the illegal board, the pseudo counter Gc (0) is initialized by adding the value of 1 to the pseudo counter Gc via cpu to initialize the change of the pulse signal at any of the terminals a ', b', c ', and d'. To 329), the pseudo counter Gc has the same value as the determination counter Hc (0 to 329).

When a game ball normally wins the electric powered accessory 57 and passes through a specific area, a game ball detector for detecting the winning ball generates a game ball detection signal. D is output. When there is no illegal board,
The signal is immediately input to the relay terminals c and d, and it is determined whether or not a big hit (= 7) based on the value of the determination counter Hc (0 to 329) when the signal is input. However, in the case of an illegal board, the pseudo counter Gc (0 to 329) is not output immediately from the terminals e ′ and f ′ to the relay terminals c and d.
Of the terminal e ′, f ′ when the value of
From the relay terminals c and d. Then, upon receiving the signal, the CPU of the game control device determines the judgment counter Hc.
When the value of (0 to 329) is read, "7 (specific value)" is selected, and it is determined that a big hit has occurred.

As described above, the illegal board is determined by the judgment counter H.
pseudo counter Gc (0) having the same value as c (0-329).
-329), the pulse from the game ball detector can be output at the timing of the big hit, so that the big hit can be easily generated. Note that the jackpot on the illegal board is set to be executable when a predetermined condition is satisfied, so it is difficult for a staff member to see through.

(First Embodiment) Next, a method of preventing improper operation when an improper board is attached will be described with reference to a control flow shown in FIG. When the power is turned on, the same processes as those in FIG. 3A are performed, and therefore the same reference numerals are given and the description is omitted (FIG. 4A).

First, a judgment counter Hc (0 to 329) is created (S20, S21, S22). Then, it is determined whether or not the value of the display data D is 15 (S2).
3). When the value of the display data D is 15, it means that each segment Li (i = 1 to 7) of the numeric display is turned off (see the table of FIG. 2). Then, when the value of the display data D is not 15, 1 is added to the display counter C (S24). Otherwise, the adding process is not performed and the same value is maintained. Next, when the display counter C is 0 to 7
(S25, S26).

As described above, when the value of the display data D is not 15, that is, when there is no display data, the display counter C maintains the same value, so that the terminals a, b, c, and d do not change at all. , The pseudo counter Gc (0 to 329) cannot perform addition processing. As a result, the pseudo counter G
c (0-329) has a value different from that of the judgment counter Hc (0-329). Therefore, even when the game ball detection signal of the winning ball is received, the timing at which the value of the determination counter Hc (0 to 329) becomes a big hit (= 7) is not known, which makes cheating difficult. As described above, even if the processing of the display counter C is performed, the processing is performed at the time of the display data D that does not need to be displayed.

(Second Embodiment) This embodiment will be described with reference to a control flow shown in FIG. When the power is turned on, as shown in FIG. 5A, the determination counter Hc and the count counter i are initialized, and 15 is written in the display data D (S30, S31). And
The determination counter Hc is created so as to have a circulation number of 0 to 329 (S41, S42, S43), 1 is added to the count counter i (S44), and it is determined whether the value is 5 or more (S45). ). When the count counter i becomes 5 or more, 1 is added to the display counter C (S46). Otherwise, the addition process is not performed and the same value is maintained.

By this measure, the display counter C keeps the same value up to four reset times after the power is turned on.
Incidentally, the value "5" of this step 45 is arbitrary. Also,
Since the display counter C has not been initialized, it is not always counted from "0". Therefore, if the false counter Gc (0 to 329) on the illegal board is added, the initialization is not performed. When the determination is being performed using the value of the display counter C, the determination counter Hc (0 to 329) has already been set.
Can be prevented since the value is different from the value of the display counter C, as described above.
The output terminals a, b, c, and d of the pseudo counter Gc (0 to 329) do not change at all, that is, by providing a pulse signal non-output state.
The value is different from 9).

Then, processing is performed so that the display counter C has a circulation number of 0 to 7 (S47, S48). As described above, by maintaining the display counter C at the same value for a predetermined time after the power is turned on, a pulse signal non-output state occurs, and the pseudo counter Gc (0 to 329) cannot perform addition processing. Since the pseudo counter Gc (0-329) has a different value from the determination counter Hc (0-329),
Fraud can be prevented.

That is, by providing a pulse signal non-output state with respect to the value of the display counter C, the false counter Gc (0 to 329) of the illegal board is changed to the judgment counter Hc (0 to 329).
329), which prevents fraud.
Therefore, in a gaming machine, when there is a pulse signal that can correspond to the determination counter Hc (0 to 329) in addition to the numeric display, as in the present invention, the pulse signal is transmitted under a predetermined condition, particularly for a game. Shutting down under non-affecting conditions is an effective measure.

(Third Embodiment) This embodiment will be described with reference to a control block shown in FIG.
The differences from the control block diagram shown in Fig.
The difference is that the output form of the display counter C is different. The output of the display counter C is 4 bits (a, b, c,
d) instead of the eight terminals (a to
h). That is, the value of the display counter C is a circulation number of 0 to 7, but the outputs of the terminals (a to h) are sequentially turned on every one reset time as shown in the lower right table of FIG. (Pulse) is output. Each segment Li (i = 1 to 7) of the numerical display is displayed through the AND element and the value of the decoder D, so that it is the same as in the first and second embodiments.

On the other hand, the illegal substrate is connected to the terminals a to h (a ′).
To h ′) by the logical sum of the pulses Gc
(0-329), the judgment counter Hc (0-
329) and a synchronization value can be taken. However, as in the first and second embodiments (FIGS. 4 and 5), by providing the display counter C with the pulse signal non-output state, the false counter Gc (0 to 3) of the incorrect board is provided.
29) is different from the judgment counter Hc (0 to 329), so that fraudulent acts can be prevented. It is needless to say that even if the pseudo counter Gc on the illegal board is constituted by any one of the terminals a to h or a pulse signal output from a plurality of terminals, the illegal countermeasure can be achieved.

Although the display counter C has a 4-bit configuration, one bit (a) for outputting all signals for each reset is provided.
And the configuration that eliminates the decoder D, that is, the decoder C
It is needless to say that it may be configured to act as an analog switch and to display a numeric display, and that the above embodiments are not performed independently.
The embodiments may be appropriately combined and configured.

[0024]

According to the first aspect of the present invention, the gaming machine has a pulse signal non-output state in which the display counter C does not output a pulse signal to the numeric display. Therefore, even if an illegal board is attached, the gaming machine is synchronized with the determination counter. Counter cannot be provided, and fraudulent acts can be prevented. Further, since the gaming machine according to the second aspect performs the non-output state of the pulse signal when there is no display data D, it is possible to prevent improper operation without affecting the numerical display.
