Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko game machine equipped with so-called electric accessories.

2. Description of the Related Art Pachinko machines, which use pachinko balls to play games, have become popular and are widely popular as a convenient form of leisure.

As is well known, pachinko machines have multiple winning holes on the board, and when a player hits a purchased pachinko ball along the board, there is a certain probability that the pachinko ball will hit the winning hole. The number of prize balls will be refunded. In such pachinko machines, the only operation that the player has to do is to put the purchased pachinko balls into the supply tray and hit the ball with the ball hitting handle, which tends to make the lively game monotonous, and it is difficult to collect a large number of prize balls. A high degree of skill is required to obtain these prize balls, and it is extremely rare for an ordinary player to receive a large number of prize balls.

Therefore, various electric accessories have been developed in order to change the game content and improve the service.

In general, pachinko machines equipped with electric accessories have a relatively low occurrence rate, but they have a common feature that the winning rate increases rapidly when a specific game state called a jackpot occurs, so it is difficult to play games with low skill level. It has gained the support of many gamers who sometimes have the opportunity to win a large amount of prize balls.

This type of pachinko machine changes the player's profit status in response to the ever-changing gaming conditions in the traditional pachinko game, so the premise is to understand the causative gaming condition and its Certain rules must be established between the game states that occur as a result, and these rules must be followed correctly.

For example, if the same type of pachinko machine has different rules applied to each machine or to each gaming parlor, it can be imagined that unnecessary troubles will occur between the players and the parlors. It's not difficult.

By the way, in this type of pachinko game machine, the resulting game state is derived in response to the detection of the game state that causes the occurrence of the game from time to time, so in order to correctly follow the above rules, it is necessary to detect the cause of the game that occurs from time to time. It must be ensured that the gaming state can be detected accurately.

However, some game parlors intentionally tamper with the sensors used to detect the gaming conditions that cause the above-mentioned problems in order to stimulate the gambling spirit of players, or to set up machines such as service tables and collection tables. As mentioned above, if such intentional manipulation is done, it will lead to distrust among the players and cause unnecessary trouble.

The present invention has been made in view of the current situation, and is designed to prevent the entire gaming machine from operating normally if there is an abnormality in the sensor that detects the occurrence of the gaming state that causes it, thereby reducing communication with players. The purpose is to prevent problems between them.

The main structure and other objects of the present invention will become clearer from the following description of embodiments with reference to the drawings.

FIG. 1 is an external view of a pachinko game machine 100 showing an embodiment of the present invention. In the game section 102 surrounded by the guide rail 101 of the pachinko game machine 100 of this embodiment, a ticket 103, a winning hole 104, a winning jack 105, and a specific ball winning area 120 that triggers the start of the slot game are arranged. In addition, an out hole 106 is provided for collecting pachinko balls that have not won in any of the winning areas.

Further, below these, there is a supply tray 150 that guides the pachinko balls purchased by the player one by one to the hitting position and refunds the prize balls, a receiving tray 160 that refunds surplus prize balls that cannot be fully refunded to the supply tray 150, and effects. A speaker 171 for generating sound and a ball hitting device 180 are each provided.

Further, in the center of the gaming section 102, a display area 110 and a variable winning device 130, which are one of the features of this embodiment, are provided.

First, the main purpose of the display area 110 is to play a slot game in conjunction with the pachinko game, and the opening mode of the variable prize winning device 130 is determined in accordance with the game result.

Specifically, as shown in FIG.
It is equipped with a time display section 215 whose lighting position moves every 3 seconds after the opening time of 30, and a game rights number display section 128 that stores and displays the number of game rights. Upon winning the prize, the electrically variable display device 111 starts operating,
The display is updated. When the player presses the stop switch 141, the update is stopped and the slot game ends. Then, the opening mode of the variable prize winning device 130 is determined in accordance with the display mode of the electrically variable display device 111 after the end of the slot game.

In this embodiment, the results of the slot game using the electrically variable display device 111 are (1) a jackpot where all four digits are displayed as [7], and (2) a jackpot where the bottom three digits become [7] or a four-digit number. Three types of situations are assumed: a middle hit where the digits match other than [7], and (3) a miss other than the above, and in the case of a jackpot, the variable prize winning device 130 is opened for a relatively long time and the middle hit is made. In the case of , the variable winning device 130 opens in a relatively short time, and in the case of a loss, the variable winning device 130 opens instantly.

In this way, in the present invention, each specific ball winning area 120
Since winning a prize is a trigger for starting the slot game, the specific installation location is not shown, but a specific ball detector is installed inside each specific ball winning area 120 to detect a winning inside. It is necessary to be Note that this specific ball detector is constituted by, for example, a micro switch or the like, but any structure may be used as long as it can reliably detect the winning of each specific ball into the winning area 120.

Further, in this embodiment, the variable winning device 130 is internally divided into a plurality of winning areas, and some of the winning areas inside are defined as a special ball winning area 402. If a prize is won in the special ball winning area 402 while the variable winning device 130 is open for a long time due to transition to a special game, the variable winning device 130 is opened again after the long time opening is completed. Repeat the development of time.

Details regarding the variable winning device 130 will be described later, but to summarize, the variable winning device 130 is a winning device configured such that when opened, the internal winning rate increases, and when activated, the internal winning rate decreases. It is a ball device.

Therefore, once a jackpot occurs as a result of a slot game, there is a possibility that an extremely large number of pachinko balls will win in the variable winning device 130, and it is difficult to grasp the number of winning balls during this special game due to various variable factors. There is something. Therefore, in this embodiment, the end period of this special game is controlled by taking into account the number of winning balls to the variable winning device, which makes it easier for the game parlor to manage the machines, and also allows the game to attract many players. It will also be possible to provide fair and appropriate services to people.

In addition, Fig. 3 and Fig. 4 show one of the above variable prize winning devices.
Give an example.

FIG. 3 is a perspective view of the variable prize winning device 130,
The illustrated variable winning device 130 is internally divided into three winning areas, the center of which is defined as the above-described special ball winning area 402, and both sides thereof are defined as general winning areas 105a and 105b. These winning areas penetrate the game board surface and communicate with the winning ball collection gutter.

Although omitted in FIG. 3 to show the internal configuration, the special ball winning area 402
The general winning areas 105a and 105b are covered with a door that is opened and closed by a driving means such as a solenoid, and when this door opens and closes, the variable winning device 13
0 is open or closed.

In the present embodiment, when the slot game shifts to a special game and the variable winning device 130 is in an open state for a long time, the variable winning device 1
When a predetermined number of pachinko balls (for example, 10) are won within 30, the variable winning device 130 is closed even if the predetermined time has not elapsed, and pachinko balls are placed in the special ball winning area 402 during each special game. When a prize is won, the variable winning device 130 opens the special ball winning area 40 again for a long time after closing due to the passage of a set time or winning of a predetermined number of pachinko balls.
Since winning in the special ball winning area 402 and winning in the variable winning device 130 are one of the conditions for controlling the variable winning device 130 itself.
A sensor is required to detect winnings to and winnings to the variable winning device 130.

By the way, winning in the variable winning device 130 is one of the control conditions of the variable winning device 130 itself as described above, so it has a large effect on the profits of the players, and the detection accuracy of the sensor is also required to be higher. On the other hand, since the variable prize winning device 130 is usually provided below the game board surface, it is easily affected by temporary ball jams and the like. Therefore, in this embodiment, the above-mentioned sensor arrangement locations are devised as shown in FIG. 4.

In FIG. 4, 401 is the special ball winning area 40

It is designed not to be affected by the pachinko balls stored inside.

In addition, the special ball detector 401 and the winning ball detector 40
In addition to the micro switch, 5,406 is also composed of a photoelectric sensor whose optical path is interrupted by the passing of a pachinko ball, but the structure itself can be used as long as it can reliably detect the passing of a pachinko ball. It can be anything.

Next, the operation of this embodiment when a player plays a game using the pachinko game machine according to this embodiment will be explained.

First, the player places the purchased pachinko balls into supply tray 1.
50, and these pachinko balls are guided to the hitting position one by one. Next, the player operates the ball hitting device 180 to hit a pachinko ball with an appropriate force.

The launched pachinko ball is guide rail 10
2 into the gaming section 102, and the gaming section 10
Fall 2. In the process of falling along the gaming section 102, some pachinko balls land in any winning area, while others fall into the out hole 1 without winning.
It will be collected on 06. In addition, since the variable winning device 130 is closed in the initial state, no pachinko balls will be won there.

In the process of continuing the game in this way, if a pachinko ball wins in any specific ball winning area 120, the specific ball winning area 120 where the pachinko ball won
A specific ball detector 121 inside generates a specific ball detection signal.

This specific ball detection signal corresponds to the synchronous differential circuit 1
23a, b, c, synchronous differentiation circuit 123
a, b, and c convert this specific ball detection signal into pulses in synchronization with the pulses applied from the phase shift pulse generation circuit 122. Then, the phase shift pulse generation circuit 122
Since the phases of the pulses applied to each synchronous differentiation circuit 123a, b, and c are all shifted from each other, even if there are winning balls in multiple specific ball winning areas 120 at the same time,
All of these winning balls are accepted by the shift register 126, which will be described later, as valid balls.

The pulses generated by the synchronous differentiating circuits 123a, b, and c pass through the OR gate 124 and pass through the AND gate 1.
However, since the AND gate 125 is open in the initial state, the pulse generated by the synchronous differentiator circuit due to the generation of the specific ball detection signal passes through the AND gate 125 and is transferred to the shift register 12.
6 and shifts shift register 126 to the right. This shift register 126 has a 4-bit output, and when the output of the 4th bit becomes H level, the AND gate 125 is closed. Therefore, the shift register 126 can continuously receive up to four specific ball detection signals.

The output of each stage of the shift register 126 is amplified by a driver 129 and drives the game rights number display sections 128a, b, c, d, thereby informing the player how many slot games he/she currently has the right to play. Note that the shift register is shifted to the right by the generation of the specific ball detection signal, and shifted to the left by the output of the synchronous differentiation circuit 127 every time a slot game starts, so that the number of rights for each game display section 128
When a, b, c, and d are lit, it indicates that you have the right to play the slot game once, twice, three times, and four times, respectively.

On the other hand, the output of each stage of the shift register 126 is applied to the flip-flop 131 via an OR gate 132. Therefore, when the shift register 126 is shifted to the right by one stage or more by the specific ball detection signal, the D input of the flip-flop 131 is applied to the flip-flop 131. becomes H level. Therefore, the flip-flop 131 is set at the timing when the pulse is applied from the phase shift pulse generating circuit 127 via the AND gate, and the flip-flop 131 stores the generation of the specific ball detection signal.

The rising edge of the Q output of this flip-flop 131 is the flip-flop 133a, b,
Since the D inputs of flip-flops 133a, b, c, and d are pulled up by the power supply, flip-flops 133a, b, c, and d are set and their Q outputs are used as the AND gates. 132a, b, c, and d are opened all at once.

A clock φ2 is applied to the other input of the AND gates 132a, b, c, d, and the clock φ2 passes through the AND gates 132a, b, c, d to the ring counter 113 shown in FIG. 5B.
added to a, b, c, d, ring counter 11
3a, b, c, and d are updated all at once.

The counting output of the ring counter 113a is directly applied to the decoder driver 112a, and the counting output of the ring counters 113b, c, d is applied to the selector 1.
14b, c, d, selector 114
b, c, and d select their A input side in the normal state, so the ring counters 113a,
The counting outputs of b, c, and d are all sent to the decoder driver 1.
12a, b, c, d, and the decoder drivers 112a, b, c, d are added to the ring counter 113.
The count outputs of a, b, c, and d are decoded and displayed on electrically variable display devices 111a, b, c, and d.

Therefore, the electrically variable display devices 111a, b,
The numerical values displayed by c and d are updated at high speed in synchronization with clock φ2.

On the other hand, the Q output of the flip-flop 133d of FIG. 5A is applied via a connection point L to the sound effect generating circuit 216 shown in FIG. 5C to drive it. Therefore, the sound effect generating circuit 216 generates a sound effect signal indicating that the slot game is in progress, and this signal is amplified by the driver 217, and the speaker 171 generates a sound effect signal indicating that the slot game is in progress.

Also, at this time, the flip-flop 131 (FIG. 5A)
The Q output of the flip-flop 131 is applied to a synchronous differentiation circuit 127, and when the Q output of the flip-flop 131 becomes H level, the synchronous differentiation circuit 127 operates the shift register 126 in synchronization with the pulse applied from the phase shift pulse generation circuit 122. The number of slot game rights indicated by the number of game rights display sections 128a, b, c, and d is also decreased accordingly.

After the slot game has started in this way, the player can press the stop switch 14 at any time.
When 1 is pressed, the stop signal passes through OR gate 143 and is applied to the clock terminal of flip-flop 144. The Q output of the flip-flop 131 is applied to the D input of the flip-flop 144, and since this signal is at H level when a slot game is being played, the flip-flop 144 is set and the phase shift pulse generation circuit 145
Cancels the reset state. A clock φ1 is applied to the phase shift pulse generation circuit 145 via an AND gate 146.
5 applies a reset signal sequentially to the flip-flops 133a, b, c, d upon release of the reset state, and therefore the AND gates 132a, b, c, d
are closed sequentially, and the ring counters 113a, b, c,
Since the count-up clock is no longer applied to d (see FIG. 5B), the electrically variable display device 1
The display of 11a, b, c, and d also stops here.
At this time, the AND gate 146 is activated at the timing when the Q4 output of the phase shift pulse generation circuit 145 rises.
is closed, so no clock is applied to the phase shift pulse generation circuit 145, and therefore the phase shift pulse generation circuit 145 maintains the Q4 output rising until it is reset.

Further, in this embodiment, the stop means 140 is provided with a timer counter 142 for ending the slot game when the player forgets to press the stop switch 141.

That is, the timer counter 142 is released from the reset state when the Q output of the flip-flop 13 rises at the start of the slot game, and counts the clock φ2. If the player does not press the stop switch 141 even after a predetermined period of time (for example, 4 seconds) has elapsed, a carry over signal from the timer counter 142 is applied to the flip-flop 144 via the OR gate 143. It acts in the same way.

Therefore, according to this embodiment, even if the player forgets to press the stop switch 141, the slot game will automatically end 4 seconds after the start of the slot game.

When the slot game ends in this way,
A signal for resetting the flip-flop 133d is sent to the determination circuit 201 (fifth circuit) via the connection point E.
(see Figure C) to activate the determination circuit 201.

The determination circuit 201 is basically constituted by AND logic, and determines the result of the slot game when it becomes active. The determination circuit 201 has a fifth
The counting outputs of the ring counters 113a, b, c, and d in FIG.

As already mentioned, the specific criteria for judgment are as follows.

(1) 4-digit ring counter 113a, b, c, d
When all the numerical outputs show [7], a signal a is generated as a jackpot, and the game shifts to a special game.

(2) 4-digit ring counter 113a, b, c, d
When all numerical outputs other than [7] are obtained, or when only the outputs of ring counters 113a, b, and c excluding ring counter 113d become [7], a signal b is generated as a middle hit.

(3) In cases other than (1) and (2) above, the signal c
occurs.

Therefore, first, the operation will be explained for the case (3) above, and then the operation will be explained for the case (1) above. In addition, in the case of (2), the variable prize winning device 130
The operation is the same as in case (1) except that the opening time is 8 seconds, so a redundant explanation will be omitted.

First, the c output of the determination circuit 201 is the OR gate 2
09 to the driver 211, and the driver 211 amplifies this and drives the solenoid 212, so the variable prize winning device 130 is opened.
On the other hand, since the c output of the determination circuit 201 is applied to the sound effect generation circuit 216, the speaker 171 generates a sound effect indicating that the result of the slot game is a loss.

Further, the output of the determination circuit 201 at point c is also applied to the AND gate 204, which opens the AND gate 204.

On the other hand, as the output of the OR gate 209 rises, the timer counter 202 is released from the reset state, and the timer counter 202 resets to the clock φ2.
count. Then, when 0.4 seconds have elapsed, the output of the timer counter 202 is the AND gate 20.
4・OR gate 210・Connection point K・OR gate 1
50 (FIG. 5A), is applied to the clock input terminal of flip-flop 148 to set it, and is further applied to flip-flop 144 and flip-flop 1 through OR gate 149.
31.

First, by resetting the flip-flop 144, the phase shift pulse generating circuit 145 is reset, and its Q4 output is lowered to the L level. This Q4 output is then sent to the judgment circuit 20 via connection point E.
1 (FIG. 5C) to activate it, so when this signal goes to L level, the determination circuit lowers its c output, and the solenoid 212 closes the variable prize winning device 130.

At this time, the output of the OR gate 209 rises, so that the timer counter 202 is reset, and the sound effect generation circuit 216 also stops generating sound effects.

Furthermore, since the flip-flop 148 (FIG. 5A) is set, its output closes the AND gate 152, and no clock is transmitted to the flip-flop 131 for a predetermined period of time. Therefore, even if two or more specific ball detection signals are generated, the next slot game will not be played immediately.
Flip-flop 1 is set by timer counter 147.
After 48 is reset, the next slot game is played.

That is, by setting the flip-flop 148, the timer counter 147 is released from the reset state and counts the clock φ2. Then, after a predetermined period of time (for example, 2 seconds) has elapsed, the timer counter 1
47, the flip-flop 148 is reset and the AND gate 152 is opened, and the flip-flop 131 receives the clock from the phase shift pulse generation circuit 122, so that the shift register 1
26 stores two or more specific ball detection signals, the flip-flop 131 is reset and the above-described operation is repeated again.

Next, in the case of (1) above, that is, [7.7.7.7]
The case where the slot game ends will be explained.

The operation when the slot game ends with the displayed content as [7.7.7.7] is summarized as follows.

(a) Basically, the variable prize winning device 130 is opened for 30 seconds by the action of the timer counter 202.

(b) Also, if, for example, 10 or more pachinko balls are won in the variable winning device 130 during this 30 second opening period, this long opening period will end even if the above 30 second period does not elapse. do.

(c) Also, if a pachinko ball wins in the special ball winning area 402 during the period of 30 seconds or until 10 balls win, this long winning period is repeated continuously, for example, up to 10 times.

(d) Furthermore, when in the open state for a long time, the display contents of the display area 110 are changed,
To inform the player of the winning status, etc.

It would be redundant to explain these at once, so each content will be explained separately below.

First, at the end of the slot game, the Q4 output of the phase shift pulse generation circuit 145 is logic 1, and the determination circuit 201 is active. The circuit 2 determines that the result of the slot game is [7.7.7.7].
01 makes signal a logic 1. At this point, the other input of the AND gate 203 is logic 1, so the signal a passes through the AND gate 203 and activates the solenoid 212, causing the variable prize winning device 130 to operate.
is opened, and the reset state of the timer counter 202 is released. Also, a of the determination circuit 201
The output is applied to the sound effect generation circuit 216, and the speaker 171 generates a sound effect indicating a jackpot.

When 30 seconds have passed after the reset state is released, the timer counter 202 turns on the AND gate 206, and the pulse that has passed through the AND gate 206 is sent to the AND gate 242 via the OR gate 2461 at connection point X and D in FIG. Added.

This point will be explained in detail later, but if no pachinko balls are won in the special ball winning area 402 during the 30 second period, the flip-flop 241 is in the reset state, and therefore the AND gate 242 is in the on state. The output of the AND gate 242 is applied to the clock input terminal of the flip-flop 148 via the OR gate 150 of connection point J and FIG. Reset.

Thereafter, by resetting the phase shift pulse generation circuit 145 in the same manner as described above, the determination circuit 2
01 is released from the active state and stops the signal a. Therefore, no driving current is applied to the solenoid 21 either, and the variable prize winning device 130 finishes opening for 30 seconds.

Further, since the drive signal is no longer applied to the sound effect generation circuit 216, the sound effect indicating the jackpot state is also stopped.

Also, while the variable winning device 130 is open for 30 seconds in this way, there is a certain probability that the variable winning device 1
There is a winning pachinko ball within 30. Since this probability varies depending on various factors, it is difficult to provide fair services to all players.

Therefore, in the present invention, when the number of winning balls to the variable winning device 130 reaches a predetermined number (10 balls in this embodiment), the variable winning device 130 is closed even during a period of 30 seconds.

Specifically, due to the occurrence of a jackpot, the winning ball counter 252 (see FIG. 5D) is released from the reset state.

Also, when a pachinko ball wins in the variable winning device 130, the special ball detector 401 and the winning ball detector 40
5,406 generates a detection signal.

This detection signal is transmitted to each corresponding synchronous differentiator circuit 24.
7, 248, 249, but pulses having different phases are applied to the synchronous differentiating circuits 247, 248, 249 from the phase shift pulse generating circuit 251, and the synchronous differentiating circuits 247, 248, 2
49 outputs a pulse in synchronization with this pulse.
In this way, in this embodiment, the detection signals are received using pulses with different phases, so even if the detection signals are generated at the same time, no detection will be missed.

And synchronous differentiation circuits 247, 248, 249
The generated pulse is applied to the winning ball counter 252 via the OR gate 250, and the winning ball counter 252 is counted up. The most significant digit output of this winning ball counter 252 is added to the above-mentioned OR gate 2461. Therefore, if there are, for example, 10 winning balls in the variable winning device 130, and the winning ball counter 252 carries, the carry over The signal is applied to AND gate 242 via OR gates 2461 and 246.

As mentioned above, when the special ball detection signal is not generated (that is, the general winning area 1 in the variable winning device 130
When a pachinko ball wins only in 05a and 05b), the flip-flop 241 is in the reset state, and therefore the AND gate 242 is in the on state. The output of the AND gate 242 is applied to the clock input terminal of the flip-flop 148 via the OR gate 150 of connection point J and FIG. Reset.

Thereafter, by resetting the phase shift pulse generation circuit 145 in the same manner as described above, the determination circuit 2
01 is released from the active state and stops the signal a. Therefore, no drive current is applied to the solenoid 212 either, and the variable prize winning device 130 ends opening even if the 30 second period has not elapsed. or,
Since the drive signal is no longer applied to the sound effect generation circuit 216, the sound effect indicating the jackpot state also stops.

Also, as described above, the variable prize winning device 130 receives 30
If it is opened for a second or until there are 10 winning balls inside, there is a certain probability that the special ball winning area 4 will be entered.
Pachinko balls also win in 02. When a pachinko ball enters the special ball winning area 402, the above-mentioned opening is repeated for 30 seconds or until 10 winning balls enter the inside, up to 10 times, as described below.

When the result of the slot game is [7.7.7.7], the output of the AND gate 203 becomes H level,
This level is passed through the connection point W to the AND gate 24.
0 (positive logic control input).

Furthermore, the most significant digit signal of the continuation counter 245 is applied to the other control input (negative logic control input) of the AND gate 240, but the output of the continuation counter 245 is at L level at this point. , AND gate 240 is in a state where it can pass the special sphere detection signal.

Now, when a pachinko ball enters the special ball winning area 402 and the special ball detector 401 generates a special ball detection signal, this detection signal is applied to the clock input of the flip-flop 241 via the AND gate 240. Since the D input of flip-flop 241 is always pulled up, flip-flop 241 is set, its output becomes a logic 0, and AND gate 242 is closed.

As already mentioned, when the variable winning device 130 is opened and 30 seconds have elapsed, or when 10 pachinko balls enter the variable winning device 130, the AND gate 242 and the OR gate 2461 and the OR gate 246 are opened. A pulse is applied to the clock terminal of flip-flop 243, but this pulse does not pass through AND gate 242 because AND gate 242 is closed at this time. Therefore, the fifth
Since the phase shift pulse generation circuit 145 in FIG. A is not reset, the determination circuit 201 continues to output the signal a.

On the other hand, since the Q output of flip-flop 241, which is set at this point, is applied to the D input terminal of flip-flop 243, flip-flop 243 is set when the clock is applied, and its output becomes logic 0. Therefore, the AND gate 203 (FIG. 5C) temporarily closes and temporarily cuts off the signal a of the determination circuit 201.

Therefore, the drive current of the solenoid 212 is temporarily cut off, and the variable prize winning device 130 is also temporarily closed.

Furthermore, since the flip-flop 243 is set, the timer counter 244 is also released from the reset state and counts the clock φ2. Then, when the set time (for example, 2 seconds) has elapsed, the timer counter 244 resets the flip-flop 243. Therefore, the output of the AND gate 203 rises again, and the variable winning device 130 opens again for 30 seconds or until 10 pachinko balls enter the variable winning device 130. Since the control input terminal of the AND gate 240 remains at logic 1 during this opening period of 30 seconds or until 10 pachinko balls are won in the variable winning device 130, the flip-flop 241 can receive the special ball detection signal. Therefore, if a pachinko ball wins in the special ball winning area 402 during this period, the above operation is repeated,
The variable winning device 130 repeats opening for a maximum of 30 seconds.

By the way, the output of the AND gate 203 rises every time the variable winning device 130 repeats opening for a maximum of 30 seconds, and this rising edge is applied to the clock terminal of the continuation number counter 245 via the connection point W, and is counted up. . When the opening for a maximum of 30 seconds is repeated 10 times in a row, the continuation number counter 245 carries over and the AND gate 240 is closed. Therefore, even if a prize is won in the special ball winning area 402 during this period, the special ball detection signal will not be accepted by the flip-flop 241.

Therefore, the flip-flop 241, AND gate 242, and flip-flop 243 are in the same state as in the case where no prize is won in the special ball winning area 402 described above. Therefore, if a period of 30 seconds passes after the variable winning device 130 is opened, or if 10 pachinko balls win in the variable winning device 130, it is the same as the case where no prize is won in the special ball winning area 402 described above. The entire device is initialized.

By the way, as mentioned above, in this embodiment, when the result of the slot game becomes a jackpot and the slot game shifts to a special game, the opening time of the variable winning device 130 is not constant, and the variable winning device 130 is opened for a maximum of 30 seconds. Even if a pachinko ball wins in the special ball winning area 402 at the same time, the variable winning device 130 does not necessarily repeat the opening for a maximum of 30 seconds again.

Therefore, there is a risk that troubles may occur between players, and in order to prevent this trouble, in this embodiment, changes in the gaming state are displayed in the display area 110.
It is arranged so that notification can be made to the players at the time.

Specific notification contents include, for example, the opening time of the variable winning device 130, the number of winning balls to the variable winning device 130 within the opening time of up to 30 seconds,
The number of repetitions of the special game for a maximum of 30 seconds and other things are assumed.

First, when the determination circuit 201 generates the signal a, the shift register 213 is released from the reset state, and
Count clock φ2. This shift register 213 is configured to shift its output by 1 bit every 3 seconds, and the driver 21
4 amplifies this and adds it to the time display minute 215.
This time display section 215 is composed of a light emitting diode or the like, and numerical values 1 to 10 are displayed on its surface as shown in FIG. Therefore, the lighting position of this time display section 215 moves every three seconds after the transition to the special game, indicating to the player how many seconds the variable prize winning device 130 has been open.

Further, the signal a generated by the determination circuit 201 when the game shifts to the special game is applied to the select terminals A/B of the data selectors 114b, c, and d via point P. As a result, data selectors 114b, c,
d selects the B side input and decoder driver 112
Add to b, c, d.

First, the output of the winning ball counter 252 shown in FIG. and added to the electrically variable display devices 111b,c.

Therefore, when a jackpot state occurs, the number of pachinko balls won by the variable winning device 130 during the period of the jackpot state is displayed on the electrically variable display device 111b,
Even if the variable prize winning device 130 closes before the 30 second period elapses, the player can understand the reason why the variable winning device 130 has closed, thereby preventing troubles with the player. .

In addition, the B side input of the data selector 114d is
The count output of the continuation counter 245 shown in FIG. 5D is applied via the connection point O, which is decoded and amplified by the decoder driver 112d and applied to the electrically variable display device 111d. Therefore, when a jackpot state occurs, the number of times the jackpot state continues due to winnings in the special ball winning area 402 during that time is displayed on the electrically variable display device 111d, and the player is informed of how many times the jackpot state continues. In addition, if a pachinko ball wins in the special ball winning area 402 during the 10th jackpot continuous state, the player can understand the reason even if the jackpot continuous state is discontinued.
Troubles with players can also be prevented.

As is clear from the above description, the pachinko gaming machine of this embodiment derives a new gaming state in response to the occurrence of the causative gaming state, and also has means for notifying players of changes in the gaming state. such as establishing
Smooth games can only be played on the premise of a relationship of trust between the player and the game parlor.

Therefore, if a sensor that detects the occurrence of a gaming situation caused by a game parlor is intentionally modified in order to increase the gambling spirit of players or to easily set up machines, it will harm the players and the game parlor. The relationship of trust between players will be seriously damaged, and the premise of pachinko games will be overturned.

Therefore, in the present invention, if a game parlor intentionally modifies the sensor that detects the occurrence of a game state that is the cause of deriving a new game state, the game is prevented from playing normally. It is designed to ensure a relationship of trust between the store and the players.

The type and location of the sensor that detects the occurrence of the gaming state that causes this differs depending on the type of pachinko game machine, but when considered based on this example, it is possible to detect a specific ball that causes the start of the slot game. 121, a stop switch 141 that causes the slot game to stop, and a winning ball detector 40 that causes the variable winning device 130 to end its long opening.
5,406, causing the variable winning device 130 to end the long-time opening and the variable winning device 13
It is possible that the special sphere detector 401 or the like causes 0 to be repeatedly opened for a long time.

Therefore, the illustrated embodiment shows an example in which the stop switch 141, winning ball detectors 405, 406, and special ball detector 401 are tampered with, making it impossible to continue normal gaming.

Generally, these sensors are routed from their respective locations to a control board using lead wires, and the lead wires and the control board are connected to each other using connectors. Since it is difficult to tamper with the control board at general game parlors, the sensor contacts are usually destroyed when fraudulent acts like the one described above are carried out.

Cut the lead wire.

Pull out the connector.

It is expected that the following methods will be adopted.

A common feature that occurs no matter which of the above modifications is performed is that the connector of the control board becomes an open loop.

Therefore, in this embodiment, in order to be able to detect any of the above cases, the winning ball detectors 405, 4
Sensors such as 06 and stop switch 141 are configured so that they are normally closed loops and become open loops when a signal is generated, and switch open detectors 261, 262, 263, and 264 are configured to open loops when the sensors in charge of them become open loops for a predetermined period of time or longer. It is determined that the sensor has been tampered with in some way.

To explain the specific effect, for example, in order to further increase the gambling spirit of players, a gaming parlor disconnects the lead wires of the winning ball detectors 405 and 406 from the connector of the control board and inserts them into the variable winning device 130. Suppose that the variable winning device 130 is kept open until a predetermined period of time has elapsed, no matter how many winning balls there are.

If such manipulation is done, the connector assigned to the sensor on the control board will always be in an open loop. However, since the loop becomes open only when a winning ball passes through the spot, it is normally impossible for the open loop to continue for more than a few seconds. Therefore, the switch open detectors 261 and 262 change the output abnormality detection signal to logic 1 when the open loop continues for more than a predetermined time.
This abnormality detection signal is the OR gate 2.
65・OR gate 1 in Figure 5 A via connection point I
Added to 49. Therefore, the output of OR gate 149 becomes a logic 1, and flip-flops 131,
144 and resets flip-flop 24 through connection H and OR gate 246.
1,243 is reset.

First, when the flip-flop 131 is reset, reception of the specific ball detection signal is refused, and when the flip-flop 144 is reset, reception of the stop signal is refused, and the flip-flop 24 is reset.
1,243 is reset, reception of the special ball detection signal will be refused, and the control circuits shown in FIGS. 5A to 5D will not be able to perform any operations.

Further, the output of the OR gate 265 is applied via the connection point Y to the AND gate 208 shown in FIG. 5C. Therefore, clock φ2 is connected to AND gate 208.
The warning display means 2 is amplified by the driver.
22. Therefore, the player can know that the pachinko game machine has been modified in some way.

Further, at this time, in conjunction with the display on the warning display means 222, a warning sound by a buzzer or the like may be used to notify that some kind of tampering has been carried out, or it may be communicated to the control room.

As explained above, according to the present invention, game parlors cannot take palliative measures such as adding tricks to the internal circuits of pachinko machines.
All pachinko gaming machines of the same type perform the same control operations, ensuring a relationship of trust between the gaming parlor and the players.

It goes without saying that the location of the switch open detector is not limited to the above.

In addition, the above example shows an example in which the control means is reset when the switch open detector detects unauthorized manipulation, but there is another way to prevent accurate gaming by reducing the driving current of the motor of the firing device. Various methods may be considered, such as cutting off or turning off the power to the control circuit.
