Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko machine, and in particular, a variation that can be converted into a first state in which it is difficult to accept a batted ball or in which it does not accept a batted ball at all, and a second state in which it is easy to accept a batted ball. The present invention relates to a pachinko machine in which a winning device is provided in a gaming section.

[Prior Art] As is well known, a pachinko machine has a plurality of winning openings, variable winning devices with operating characteristics, and gaming devices appropriately arranged on the game board, so that players can If the batted ball that is fired wins a prize with a certain probability, a certain number of prize balls will be ejected to the player accordingly, or a specific variable winning device will increase the winning rate of the next ball. It is subject to change. For example, if a game device that operates a variable display is provided, and a ball hits a particular prize opening, the variable display of the game device starts, and when the display changes to a specific mode when stopped by the player's operation, it changes as a jackpot. To prevent a pachinko game from becoming monotonous by keeping a winning device in a state where the winning rate is high for a predetermined period of time, and to enable players to uniformly win a certain number of prize balls regardless of their skill at playing the game. Efforts have been made.

In this way, when maintaining and inspecting a pachinko machine in which the operation of the game device and variable prize winning device is controlled in a variety of ways by the control device at a manufacturing factory or game parlor,
In particular, in order to check the operation of the variable prize winning device or the game device, it is necessary to make a jackpot state or a small win state appear. If a prize is generated by simply hitting a ball into a specific winning slot, it is sufficient to put the ball into the specific winning slot from the outside, but as mentioned above, when the display of the game device changes to a specific format. In the case of recent pachinko machines that have sophisticated controls that allow players to hit the jackpot, even if it is possible to simply stop the game device from the outside, the game cannot freely produce the desired prize pattern. It took too much time to convert the device to the desired specific state, which was an obstacle to maintenance and inspection work.

[Problems to be Solved by the Invention] In the case of recent pachinko machines that have been equipped with various devices to enhance playability, there has been a problem in that maintenance and inspection work is time-consuming.

The present invention was made in consideration of the above circumstances, and
To provide a pachinko machine that can be easily maintained and inspected even if it is an advanced pachinko machine with high playability in which a game device and a variable prize winning device are controlled in a complicated manner.

[Means and effects for solving the problem] The above object is to provide a pachinko machine in which a variable prize winning device is provided in the gaming section, which can be converted into a first state in which it is difficult to accept batted balls or not at all, and a second state in which it is easy to accept batted balls. The machine includes a specific winning detector that detects a batted ball that enters a specific winning opening, a gaming device that starts variable display operation based on a command signal derived from the specific winning detector, and a game result display of the gaming device. a control device that converts the variable prize winning device into a second state until a predetermined condition is achieved in response to the occurrence of a specific mode based on the game device; an automatic stop means for automatically stopping the variable display operation of the game device by deriving a stop command signal by deriving a stop command signal; and an automatic stop means for automatically stopping the variable display operation of the game device; a probability control means for controlling a variable display mode based on the result display of the game device; and a probability control means for controlling a specific mode based on the result display of the game device by a command signal supplied from the outside in connection with the stoppage of the operation of the game device. This is achieved by a pachinko machine characterized by having a specific forced generation means that forcibly generates the force regardless of the situation.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an external view of a pachinko machine according to an embodiment of the present invention, and each component thereof will be explained below to the extent that it is particularly relevant to the present invention. In FIG. 1, the gaming section 11 of the pachinko machine 10 includes roulette players A to E, and a visible display section 1 of the slot game device.
2. Variable prize winning devices 13a to 13e are provided. The roulette chasers A to E are winning devices having a structure in which a light emitting element such as a small lamp or a light emitting diode is integrally incorporated into a normally widely used non-variable winning device. This constitutes a roulette game device as a game device to be described later. To give an overview of the roulette game in this embodiment, the five lighted positions of the roulette chuck cars A to E start moving under a certain specific condition, and then move under another certain condition. This is a game in which the question is which lamp out of five lamps is lit when the movement of the lighting position has stopped due to , that is, where the blinking movement of the lamp has stopped.

FIG. 2 is a diagram showing a specific configuration of the visible display section 12 of the slot game device as the game device in this embodiment. That is, the visible display section 12
includes two numeric display elements (for example, segment display) 12a and 12b that can continuously display numbers from "0" to "9", and a translucent front plate 1.
It consists of 4. The outline of the slot game in this embodiment is that two number display elements 12a, 1
2b When the display starts moving under a certain condition and stops moving under another certain condition, the question is what combination of two numeric displays causes the display to stop moving. This refers to a game where

In the pachinko machine of this embodiment, the specific conditions for starting the operation of the roulette game device and the slot game device as game devices are set for roulette chucker B or D (hereinafter referred to as roulette chucker B or D (hereinafter referred to as , and one of the conditions for stopping the operation of both game devices is the occurrence of a winning ball in the specific roulette chuckers B and D (which serve as specific winning openings), and one of the conditions for stopping the operation of both game devices is the occurrence of a winning ball in the special roulette chuckers B and D, which serve as specific winning openings. The stop switch 15 is to be pressed by the player himself. Therefore, Roulette Chuckers B and D, which are specific Roulette Chuckers, are equipped with a first specific winning detector for detecting the occurrence of a winning ball.

FIG. 3 shows a variable prize winning device 13a in which a pair of movable wings are opened and closed by energizing and deenergizing a solenoid;
It is an exploded view showing the specific structure of 13b and 13c. The operating principle of the variable prize winning device 13, which opens and closes the movable wing pieces by the driving force of a solenoid, will be briefly described below. When the solenoid 31 fixed to the back side of the board 30 with screws or the like is energized, its driving force is applied to the actuating pins 33, 33 fixed to the pair of movable blades 32, 32 and passing through the board 30. transmitted via a gear mechanism 34,
As a result, the pair of movable wing pieces 32, 32 perform an opening/closing operation centering around the introduction port 35 bored in the base plate, which can be converted into a first state in which they do not receive a batted ball and a second state in which they easily accept a batted ball. It is. The illustrated variable winning device 13 is of a type in which when the solenoid 31 is deenergized, the movable wing pieces 32, 32 are completely closed, thereby eliminating any possibility of winning a prize. Even when the movable wing pieces are in the closed state, like a normal chulip-type winning device, there is still room for one pachinko machine in the pair of movable wing pieces, and there is still a possibility of winning a variable prize. It may also be a device. In addition, the three variable prize winning devices 13a, 13b,
13c, especially the variable winning device 13b, based on the winning of a specific batted ball, the variable winning device 13a, 13
A variable prize winning device (hereinafter referred to as a variable prize winning device) equipped with a second specific winning detector that issues a continuation command signal for continuously opening the buttons b and 13c to a control device 16, which will be described later and is arranged on the back side of the game board. Specific variable winning device 1
3b).

Next, the characteristic specific operation of the pachinko machine of this embodiment, which is equipped with the above-mentioned game device, variable prize winning device, game stop switch, and control device on the back side of the game board as its main components, will be explained as follows. It becomes like this.

When a ball hit by a player lands in either specific roulette chuck car B or D,
In response to this, both the roulette game device and the slot game device simultaneously start respective predetermined variable display operations. That is, as described above, the roulette game machine starts moving the lighting position of the lamp, and the slot game machine starts moving the number display. Next, when the player operates the stop switch 15 to stop the movement of both game devices, the slot game device first stops the display movement of its visible display section 12, and then, a moment later, the roulette game device turns on the lamp. Stops moving the lighting position. Depending on the combination of game results when both game devices stop operating, the following three types of gaming benefits are given to the player.

In other words, (1) When the lighting position of the lamp on the roulette game device stops at the C-chacker, and the number display on the slot game device stops at the combination of "77" (hereinafter, this case is considered to be the occurrence of a specific situation). ), the variable winning devices 13a, 13b, and 13c open sequentially, and this state in which it is easy for a batted ball to win a prize continues for, for example, 30 seconds as a predetermined condition is achieved.

(2) The number display in the slot game device stops at the combination of "77", but if the lighting position of the lamp in the roulette game device stops at a place other than the C chucker, the variable winning devices 13a, 13b, 13c will be displayed in sequence. Opening operation,
This state where it is easy for the ball to hit the prize continues for 10 seconds.

(3) If the game results of the roulette game device and the slot game device stop due to a combination other than the above (1) and (2), the variable winning device 13
a, 13b, and 13c open sequentially, and this state in which it is easy for a batted ball to win a prize continues for only 5 seconds.

In particular, when the specific aspect (1) occurs, the specific variable winning device 1
3b, if even one ball as a specific batted ball wins a prize, the variable prize winning devices 13a, 13b, 13c which are in the open operation will all close once and then open again in sequence in response to this. The state in which it is easy for a batted ball to win a prize will once again appear for 30 seconds. Thereafter, on the condition that a winning ball is generated in the specific variable winning device 13b during the opening operation of the variable winning device, the series of operations described above will be repeated.
The state in which it is easy for a batted ball to win a prize is repeatedly continued as long as the condition that a winning ball occurs in the specific variable winning device 13b within 30 seconds is satisfied each time. In this way, the state in which it is easy for a batted ball to win a prize can be continued repeatedly as long as a certain condition is satisfied each time.

The features of the pachinko machine of this embodiment, including the control of repeated and continuous motions in which the ball is likely to win, the operation control of the game device, the determination of game results, the probability control, etc., are arranged on the back side of the game board. Control device 16
Hereinafter, a circuit diagram of an embodiment of the control device 16 shown in FIG. 4 will be described in detail.

The control circuit shown in FIG. 4 is roughly divided into a game control section 100 for controlling the operation of the game device.
and a main control section 200 for determining game results and controlling opening operations of a plurality of variable prize winning devices in various ways including the above-mentioned continuous operation.

First, the game control unit 100 determines how the roulette game and the slot game are played based on the winning of a ball hit to the specific chuck car B equipped with the first specific winning detector 98 or the specific chuck car D equipped with the specific winning detector 99. Explain how it is executed. A game start command signal from the first specific winning detector 98 or 99 based on the winning is given to the winning register 103 via the OR gate 102. And the output of the winning register 103 is AND
It is given as one input of gate 104. At that time, if the other input of the AND gate 104 is given a high level signal (hereinafter referred to as H signal) by inverting the low level signal from the main control unit 200, which will be described later, the AND gate 104 The H signal is derived and the flip-flops 105, 106,
107 at the same time. In addition, if the batted ball consecutively wins a prize in a specific chuck car B or D, or if a batted ball wins a prize in a specific chuck car B or D during the opening operation of the variable winning device based on the previous prize, as described below, Entry award register 103
A game start command signal issued later is temporarily stored.

The set output (H signal) of the flip-flop 105 is given to one input of the AND gate 108, but since the other input is always given a pulse signal from the pulse oscillator 109, the corresponding
AND gate 108 is a flip-flop 105
is set, the ring counter 110
A clock pulse will be sent to the clock signal input terminal CK of the circuit. The ring counter 110 is
In synchronization with this clock pulse, the terminals that output the H signal are sequentially stepped from terminal 0 to terminal 5. When the H signal is output from terminal 5 along with the step, this signal is passed through the OR gate 111. Therefore, while receiving the clock pulse from the AND gate 108, the H signal is sequentially and cyclically applied between terminals 0 to 4 to which the driver circuit 112 is connected. It operates to output to . The driver circuit 112 is
Each output terminal 0, 1,
In response to the outputs 2, 3, and 4, the lamps c, d, e, a, and b incorporated in each roulette chuck car C, D, E, A, and B are made to blink in sequence.
As a result, the lighting position of the lamp is continuously moved on the game board of the pachinko machine, similar to a so-called roulette game.

Next, a slot game device that starts operating when flip-flops 106 and 107 are set will be described. The set output (H signal) of flip-flop 106 is applied to one input of AND gate 120. The AND gate 120 is constantly supplied with a pulse signal from the pulse oscillator 121 to its other input, and simultaneously sends a clock pulse to the clock signal input terminal CK of the decimal counter 122 when the flip-flop 106 is set. This decimal counter 122
counts the number of clock pulses sent from the AND gate 120 and connects it to its output terminal.
BCD output is sequentially output to Q _A to Q _D.
Then, the driver circuit 123 receives the sequentially changing BCD output of the decimal counter 122, and
The number display element 12b is driven. Number display element 1
2b responds to this by sequentially displaying and moving the numbers "0" to "9". Note that the display movement of the numeric display element 12a is performed by a circuit consisting of an AND gate 130, a pulse oscillator 131, a decimal counter 132, and a driver circuit 133 based on the set output (H signal) of the flip-flop 107. , the circuit configuration and its operating principle are as follows: AND gate 12 for controlling and driving the numeric display element 12b;
Since it is exactly the same as the above-mentioned circuit composed of the 0, decimal counter 122, etc., no particular explanation will be given here.

The blinking speed of the lamp in the roulette game device can be easily changed by adjusting the oscillation cycle of the pulse oscillator 109. Further, the speed of display movement of the number display elements 12b, 12a in the slot game device can be easily changed by adjusting the oscillation period of the pulse oscillators 121, 131.

Next, a description will be given of how the roulette game device and the slot game device, which have started predetermined operations in the above-described processes, respectively, stop their operations.

If the player now operates the game stop switch 15 to stop the game operation, the signal (H signal) from the switch 15 first resets the flip-flop 107 via the OR gate 150. This causes flip-flop 10 to pass from AND gate 130 to decimal counter 132.
After the number 7 is set, the continuously transmitted clock pulse is cut off, the decimal counter 132 stops counting, and the display movement of the numeric display element 12a first stops accordingly. Then, the reset output (H signal) of the flip-flop 107 is sent to the timer circuit 1.
52, the timer circuit 152 issues an H signal after a certain period of time (for example, 1 second) and resets the flip-flop 106. By resetting the flip-flop 106, the decimal counter 122 stops counting in this case as well, and the display movement of the numeric display element 12b stops. And this time, the reset output (H
signal) is given to the timer circuit 154, and the timer circuit 154 also outputs an H signal after a certain period of time (for example, 1 second) has elapsed.
A signal is issued and flip-flop 105 is reset in response. As a result, the ring counter 110
stops its stepping operation based on the interruption of the clock pulses that were continuously sent out from the AND gate 108. As a result, at the lamp corresponding to the output terminal outputting the H signal when the ring counter 110 stops stepping,
This will stop the lamp from blinking.

In addition to the manual stop circuit described above, the pachinko machine according to the present embodiment includes an automatic stop circuit as an automatic stop means that automatically stops the game operation after a certain period of time has passed after the start of the game, in addition to the manual stop circuit described above. I can see it. This automatic stop circuit is composed of a timer circuit 156 and the OR gate 150. The timer circuit 156 is connected to the set output terminal of the flip-flop 107.
As described above, the flip-flop 107 is set based on a winning in the specific roulette chucker B or D, and when a certain period of time (for example, 8 seconds) has elapsed after the set output is given, an H signal is derived and the OR gate is activated. 150 to reset flip-flop 107. In response to this, the movement of the numeric display of the numeric display element 12a is stopped, as described above. The process from when the flip-flop 106 is reset until the display movement of the numeric display element 12b is stopped, and from the time when the flip-flop 105 is reset until the blinking movement of the lamp is stopped, is based on the operation of the stop switch 15 described above. This is exactly the same as the process of stopping, and no explanation is required. By adopting this automatic stop circuit, the gaming device that once started the game operation based on winning the specific roulette chucker B or D,
It is possible to prevent failures caused by the stop switch 15 continuing to operate for a long time because the player does not operate it. Furthermore, since the automatic stop circuit automatically stops the operation of the game device, the player does not have to operate the stop switch 15 each time a winning ball lands on a specific roulette chucker B or D. It also has the advantage of reducing the inconvenience that would otherwise occur.

In addition to this game automatic stop circuit, which is a characteristic circuit of the present invention, the game control unit 100 described above includes a control device, a variable prize winning device, and a control device that can generate the specific mode at any time, as well as maintenance and inspection of the variable prize winning device and the game device. The system is equipped with a specific mode occurrence monitor circuit as a means for forcing a specific mode to occur, which is sometimes convenient, and a probability control circuit as a probability control means that makes it possible to set in advance the probability of occurrence of a specific mode, but details of these are provided. will be described later.Next, how the game results of the above-mentioned game devices are determined, and how the variable prize winning devices 13a,
13b, 13c are energized and controlled, and how the opening operation of the variable winning devices 13a, 13b, 13c is continuously maintained based on the winning of the specific variable winning device 13b.
The operation of the main control section 200 will be mainly explained.

First, the number display on the slot game device is "77".
A case where the lighting position of the lamp of the roulette game device stops at the C-chacker, that is, a case where a specific aspect occurs as a game result will be explained.

The fact that the number display element 12a of the slot game device stops at the number "7" means that the output terminal "Q _A Q _B Q _C Q _D " of the decimal counter 132 outputs "0111", and similarly the number The fact that the display element 12b stops at the number "7" means that the output terminal "Q _A Q _B Q _C Q _D " of the decimal counter 122 outputs "0111". The output terminals Q _B , Q _C , Q _D of the decimal counter 132 and the output terminals Q _B , Q _C , Q _D of the decimal counter 122 are connected to the input of a multi-input AND gate 201 , and the AND gate 201 is connected to a loop. The H signal is derived only when the game result of the let game device is "77". AND gate 20
The H signal derived from 1 is passed through the AND gate 202
and is applied to one input of AND gate 250, and is inverted and applied to AND gate 270 as an inhibit input. In addition, the ring counter 11
Since the H signal output to terminal 0 of 0 is given to the other input of AND gate 202, the AND
The gate 202 provides an H signal to one input of the AND gate 220, and also provides the AND gate 220 with an H signal.
50 and AND gate 270. And AND gate 22
The other input of 0 is given the reset output (H signal) of the flip-flop 105 at the same time as the roulette game device, which stops a moment later than the slot game device, stops its operation.
AND gate 220 derives the H signal. This H signal derived from the AND gate 220 is differentiated by the differentiating circuit 221, and is then differentiated by the OR gate 220.
2 to set the flip-flop 223. On the other hand, the set output (H signal) of flip-flop 223 is applied to one input of AND gate 226 via OR gate 225. OR gate 2
The H signal derived from 25 is also inverted and applied to the reset terminal R of shift register 228 to release shift register 228 from the reset state. The other input of the AND gate 226 is constantly given a pulse signal from the pulse oscillator 227, and the remaining input is given an inhibit input from the output terminal 3 of the shift register 228 in the initial state. Since there is, AND gate 2
26 sends a clock signal to the clock signal input terminal CK of the shift register 228.
The shift register 223 first derives an H signal from terminal 1 at the rising edge of the first pulse of this clock signal, then derives an H signal from terminal 2 at the rising edge of the second pulse, and then It operates so that an H signal is also derived from terminal 3 upon the rise of the third pulse. shift register 22
The H signal outputs derived from terminals 1, 2, and 3 of 8 sequentially start the corresponding variable prize winning devices 13a, 13b, and 13c via the driver circuit 229. The clock signal being sent from the AND gate 226 to the clock signal input terminal CK of the shift register 228 is activated when the H signal is derived from the terminal 3 of the shift register 228, that is, the variable prize winning device 13c is finally opened. When the gate opens, this H signal is applied to one input of the AND gate 226 as an inhibit input, thereby stopping its transmission. Also, shift register 2
The H signal derived from terminal 3 of the flip-flop 28 is commonly applied to one input of each of AND gates 230, 252, and 273, while the set output (H signal) of the flip-flop 223 is applied to the other input of the AND gate 230. , so the AND gate 230 derives the H signal. Based on this H signal, the timer circuit 231 derives the H signal after a certain period of time (30 seconds in the pachinko machine of this embodiment) and resets the flip-flop 223, which has been in the set state so far. As the flip-flop 223 is reset, the H signal derived from the OR gate 225 is cut off, and the shift register 22
8 returns to the initial state, ie, the reset state.
In response to this, all the variable prize winning devices 13a, 13b, 13c that opened sequentially and then continued to open for 30 seconds regulated by the timer circuit 231.
will close at the same time.

Next, the main control unit 200 controls based on the continuous operation, which is a major feature of the pachinko machine of this embodiment, that is, the occurrence of a winning ball to the specific variable winning device 13b within, for example, 30 seconds when the predetermined condition is achieved. All variable winning devices 13a, 13b, 13
A concrete explanation will be given of how the operation of opening c again for 30 seconds is performed.

Now, it is assumed that the variable prize winning devices 13a, 13b, and 13c are in the opening operation as described above based on the occurrence of a specific aspect. In this state, the set output (H signal) of the flip-flop 223 is transmitted to the AND gate 22 via the OR gate 225 as described above.
On the other hand, it is applied to one input of an AND gate 242 via a delay circuit 241, and also applied to the reset input terminal of a flip-flop 243 after being inverted. As a result, during the 30 seconds after the flip-flop 223 is set based on the occurrence of the specific condition and until it is reset by the timer circuit 231, a winning ball is won by a ball into the specific variable winning device 13b which is in the opening operation. If a continuation command signal is issued from the second specific winning detector 244 provided in connection with the variable winning device 13b, the continuation command signal activates the AND gate 242 and sets the flip-flop 243. Since the set output (H signal) of the flip-flop 243 is applied to the set input terminal of the flip-flop 223 via the OR gate 222, the flip-flop 223
As the 30 seconds regulated by the timer circuit 231 elapses, the flip-flop 223 is reset once and then immediately reset again, and based on the occurrence of a specific condition, the flip-flop 223 becomes in the same state as when it was first set. . As a result, the variable winning device 13
a, 13b, 13c are flip-flops 223
After closing for a moment in response to the reset, the valves open again sequentially through the process already described and are maintained for 30 seconds. After the flip-flop 223 is reset by the timer circuit 231, the flip-flop 243 is reset with a slight delay of the delay time of the delay circuit 241, and the winning of the specific variable winning device 13b within the newly started 30 seconds is reset. Prepare for the occurrence of a ball. In this way, if a specific situation occurs in a game device,
Every certain period of time regulated by the timer circuit 231 (in this embodiment, every 30 seconds as described above),
If there is even one winning ball in the specific variable winning device 13b, the opening operation of the variable winning devices 13a, 13b, and 13c is repeated. Therefore, AND
Gate 242 and flip-flop 243 constitute continuation means.

Next, the number display on the slot game device is "77"
A case will be described in which the roulette game machine stops at a position other than the C-chacker, but the lighting stop position of the lamp of the roulette game machine stops at a place other than the C-chacker. In this case, unlike the above-mentioned case where the specific situation occurs, the H signal is not sent from the roulette game device, so the AND
Although no H signal is derived from the gate 202,
The low level signal of AND gate 202 is inverted and an H signal is applied to one input of each of AND gate 250 and AND gate 270. Also,
The H signal of AND gate 201 is
0 is applied to the other input to enable the AND gate 250, and is inverted and applied to the AND gate 270 as an inhibit input. AND gate 2
The H signal derived from 50 is passed through AND gate 251
is applied to one input of the AND gate 25.
As mentioned above, the reset output (H signal) of the flip-flop 105 of the roulette game machine is applied to the other input of the AND gate 251.
At the same time as the game is stopped, an H signal is derived, and a flip-flop 254 is set via a fine powder circuit 253. The process in which the variable winning devices 13a, 13b, and 13c sequentially open based on the setting operation of the flip-flop 254 is exactly the same as the process in which these variable winning devices open based on the occurrence of the specific mode described above, and will not be particularly explained again. do not. Then, H is sent out from terminal 3 of the shift register 228.
The signal, in turn, activates AND gate 252. The H signal derived from the AND gate 252 is given to the timer circuit 255.
5 indicates the timer circuit 2 after the H signal is applied.
In this embodiment, when 10 seconds have elapsed, which is shorter than the time regulated by 31 (30 seconds), an H signal is sent to reset the flip-flop 254. As this flip-flop 254 is reset,
All the variable prize winning devices 13a, 13b, and 13c are closed in the same way as when the specific mode occurs.

Next, the number display on the slot game device shows "77".
A case will be described in which the roulette game device stops in a combination other than the above and the lighting stop position of the lamp of the roulette game device is other than the C-chacker. In this case, AND gate 201 and AND gate 202
No H signal is derived from either of the AND
Since the inverted H signal is applied to the two inputs of the gate 270, the AND gate 270 derives the H signal at the same time that both game devices stop. This H signal derived from the AND gate 270 is first differentiated by the differentiation circuit 271, and then
Set flip-flop 272. Based on the setting of the flip-flop 272, the variable prize winning devices 13a, 13b, and 13c sequentially open in the same manner as in the case where a specific condition occurs or the number display on the slot game device stops at "77". At this time, the H signal derived from terminal 3 of shift register 228 is applied to flip-flop 2.
72's set output (H signal) activates the AND gate 273 given to one input, and the corresponding
The H signal derived from AND gate 273 is given to timer circuit 274. timer circuit 274
is a shorter time than the time regulated by the timer circuit 255, and in this embodiment, the AND gate 2
When five seconds have elapsed since receiving the H signal derived from the flip-flop 73, the H signal is derived, thereby resetting the flip-flop 272. flipflop 2
72 is reset, all the variable winning devices 13a, 13b, and 13c close at the same time when a specific situation occurs or when the slot game device stops at the combination of numbers "77". It's exactly the same.

In addition, based on the game results of any of the game devices, the variable prize winning devices 13a, 13b, 13c
When the game device is in the opening operation, even if a ball hits a specific roulette chucker B or D, the game device will not restart its operation. Specifically, the variable winning device 13
OR when a, 13b, 13c are in opening operation
The H signal derived from the gate 225 is inverted and given to one input of the AND gate 104 in the game control section 100.
This is done by prohibiting the derivation of the H signal from.

Although the basic circuit configuration and operating principle of the control device 16 have been explained so far, the game control section 100 in particular of the control device 16 includes a probability control circuit as a probability control means of a characteristic circuit that has not been explained yet. A specific mode generation monitor circuit is included as a specific mode forced generation means, and these will be explained below.

The probability control circuit is a circuit whose purpose is to electrically set in advance the probability that a specific form as a game result will occur. 77" combination, the probability of stopping can be changed to three levels. If we calculate the probability that the specific aspect of the game result described above will occur based on winning in the specific roulette chuck car B or D under normal conditions, we will find that the lighting position of the lamp in the roulette game device is C. The probability of stopping at the chat car is 1/5,
Since the probability of stopping at the number "7" for one number display element in a slot game device is 1/10, the overall probability is 1/5 x 1/10 x 1/10 = 1/500. Become. However, if, for example, an H signal is always given to the output terminal Q _D of the decimal counter 132, the number display element 12a will move sequentially only within the range of odd numbers, and the probability of stopping at the number "7" will decrease. becomes 1/5. Therefore, in this case, the probability that the specific condition will occur is 1/5 x 1/10 x 1/5 = 1/250
Therefore, the probability is twice that of the normal case. If an H signal is always given to the output terminal Q _D of the decimal counter 122 in addition to the decimal counter 132, the numeric display element 12b will also sequentially display only within the odd number range, resulting in a specific mode. The probability of occurrence is 1/5 x 1/5 x 1/5 = 1/125, which means that the specific mode can occur with a probability four times higher than in the normal case. The selection of the probability in the game device control unit 100 of this embodiment is achieved by selectively inserting the jumper wire 161 or 162 into the terminal board 160 to which the output terminals Q _D of the decimal counter 132 and the decimal counter 122 are connected. It is done by certain things. If the jumper wire 161 is used, the probability that the specific mode will occur will be 1/250 as described above, and if the jumper wire 162 is used, the probability will be 1/125. In this way, in this example, 10
The advance counters 122, 132, the terminal plate 160, and the jumper wires 161, 162 constitute probability control means.

The specific mode generation monitor circuit as a specific mode forced generation means is a circuit that is supplied with a command signal by operating the monitor switch 170 and forcibly generates a specific mode that is one of the game results described above. At a manufacturing factory or game store,
It is extremely convenient for contractors to inspect and adjust pachinko machines for maintenance. If a trader operates the monitor switch 170 while the game device is operating, the monitor switch 170 sends out an H signal, and the AND gate 171, AND gate 172 and AND gate 1
73 is applied to each one input. At this time, AND
The other input of the gate 171 is the reset output (H
signal) is given, so the AND gate 1
71 derives the H signal and applies it to the preset terminal P of the decimal counter 132. The data input terminals P _A , P _B , P _C , and _PD of the decimal counter 132 contain the number “7”.
Since the data corresponding to is input in advance, when the H signal from the AND gate 171 is applied to the preset terminal P, the output terminals ``Q _A , Q _B , Q _C , Q _D '' are correspondingly inputted. corresponds to the number "7"
BCD output "0111" is immediately derived. The number display element 12a accordingly displays the number "7". The decimal counter 122 receives the H signal derived from the AND gate 172 at its preset terminal P, and outputs the BCD output "0111" corresponding to the number "7" to its output terminals "Q _A , Q _B , Q _C , Q _D ”, and the principle by which the number display element 12b displays the number “7” in response to this is the same as in the above case,
There is no need for further explanation.

AND gate 173 is monitor switch 17
H signal sent from 0 and flip-flop 10
It receives the reset output (H signal) of No. 5 and derives the H signal to its output. The H signal derived from the AND gate 173 is applied to the reset terminal R of the ring counter 110 via the OR gate 111.
The ring counter 110 is reset. In response to this, if the ring counter 110 had output an H signal from a terminal other than terminal 0 before this reset operation, the ring counter 110 immediately sends a signal to the roulette chuck C based on the H signal output from terminal 0. The corresponding lamp c lights up.

In this way, the specific mode forced generation means is AND
It is composed of gates 171, 172, 173, a ring counter 110, and decimal counters 122, 132, and by operating the monitor switch 170, the lighting position of the lamp of the roulette game machine can be changed to the position of the C checker. And since the combination of numbers displayed on the slot game device is "77", it is possible to forcibly produce the specific mode as the game result described above. Thereby, the operator can immediately change the game device to a specific mode without having to keep pressing the stop switch 15 until the roulette game device or slot game device is in a specific mode, and maintenance and inspection can be easily performed.

In addition, in the embodiment of the game device described above, in addition to the roulette game device, there is also a roulette game device that continuously displays numbers.
Although one number display element is provided, any number of number display elements may be used; for example, three number display elements may be provided. The game device can also be constructed from a device in which a plurality of number display elements are arranged in parallel, a device having a plurality of rotating bodies, a device using a video display device, etc.

In addition, in the above embodiment, three variable winning devices were provided in the gaming section, but one variable winning device was provided,
A second specific winning detector may be provided to detect a specific batted ball that has flown down a specific area within the variable winning device.

Further, in the above embodiment, the probability of occurrence of a specific aspect of the game device is electrically set in advance using a shamper wire, but it may be electrically set in advance by any means. For example, the connection may be made selectively in advance using a switch, or the setting may be instructed in advance using a ROM.

Further, instead of providing the manual stop circuit for manually stopping the variable display operation of the game device in the above embodiment, only an automatic stop circuit may be used.

Furthermore, in the above embodiment, the second state in which the variable prize winning device is more likely to accept batted balls is maintained until a predetermined period of time has elapsed, and the predetermined condition for maintaining the second state is a predetermined period of time.
Any other condition other than the elapsed time may be used. For example, the condition of the number of batted balls won by the variable winning device may be added to the above-mentioned constant time condition. In other words, before a certain period of time, say 30 seconds, has elapsed, the number of batted balls, say 10.
The second state in the variable winning device may be terminated if the player wins an individual prize.

[Effects of the Invention] As detailed above, according to the present invention, a variable prize winning device is provided in the gaming section that can convert between a first state in which it is difficult to accept batted balls or not at all, and a second state in which it is easy to accept batted balls. In a pachinko machine, a specific winning detector detects a batted ball that enters a specific winning opening; a game device that starts a variable display operation based on a command signal derived from the specific winning detector;
a control device that converts the variable prize winning device into a second state until a predetermined condition is achieved due to the occurrence of a specific mode based on the game result display of the game device; automatic stopping means that automatically stops the variable display operation of the game device by deriving a stop command signal when a predetermined period of time has elapsed from the start of the variable display operation;
probability control means for electrically setting the probability of occurrence of a specific mode in the game device in advance and controlling the variable display mode based on the set probability; and a specific mode forced generation means for forcibly generating a specific mode based on the result display of the game device regardless of the control of the probability control means, so that the game device or the variable prize winning device can be controlled. Even if it is an advanced pachinko machine with high gameplay that is electrically controlled in various ways by a control device,
By simply supplying a command signal from the outside, it is possible to easily generate specific conditions that are difficult to generate in the past, and this is useful for maintenance and inspection work on pachinko machines in manufacturing factories and game parlors, especially the opening and closing operations of variable prize winning devices and lighting devices. Maintenance and inspection work such as lighting status can be easily performed. In other words, in the case of a pachinko machine in which the probability of occurrence of a specific mode in the game device is electrically fixed in advance and the variable display mode is changed based on this set probability, the probability that the specific mode will occur is determined by the probability. Therefore, no matter how many times the variable display mode is stopped using the stop switch, the specific mode is not always achieved. However, in order to perform maintenance and inspection to determine whether the variable prize winning device always opens when a specific mode occurs, it is necessary to ensure that the specific mode occurs. In this manner, the present invention reliably generates the specific mode by specifying the forced generation of the specific mode, so maintenance and inspection work on pachinko machines including game devices can be easily performed.

In addition, in a pachinko machine manufacturing factory, when setting the winning rate and winning status of balls hit to the variable winning device when a specific aspect of the game device occurs during the development stage of the pachinko machine including the above-mentioned game device,
By using this specific mode forced generation means, it is possible to significantly shorten the development time of a pachinko machine.
