BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine,
More specifically, a pachinko game machine equipped with a variable winning device that is in an advantageous open state for a player when a game condition such as a hit ball, that is, a game ball launched on a game board surface, wins a specific winning opening is achieved. About.

[0002]

2. Description of the Related Art In a conventional pachinko gaming machine, a so-called tulip is generally used as a variable prize winning device which is in an advantageous open state for a player when a hit ball is hit in a specific winning opening, for example. A prize winning device referred to as a prize winning device is also used. This is, for example, as shown in Japanese Patent Publication No. 60-58984 and Japanese Patent Application Laid-Open No. 60-68883, a plate that can be opened in front of the game board, and a prize hole that can hit a ball when the plate is opened. In a normal game state, the winning opening is closed with the plate closed, but when a predetermined condition is achieved, the plate is opened and the hit ball is received in the winning opening, that is, it is advantageous for the player. It is in a state.

[0003] In these pachinko machines, the conditions for setting the variable prize winning device to the open state are as follows. In addition to the fact that a ball is hit into a specific prize hole, a start is made by entering a specific prize area as in Japanese Patent Publication No. 60-58984. The variable display device that displays a plurality of display patterns and then stops at a specific display pattern by a player's stop operation or after a certain time, or a normal display device as disclosed in Japanese Patent Application Laid-Open No. 60-68883. In a gaming state, a variable display device that sequentially lights a plurality of lamps stops in a state where a specific lamp is turned on when a specific winning area is won.

Further, in the pachinko machine of Japanese Patent Publication No. 60-58984, if a hit ball passes a specific area while the variable prize winning device is in the open state, the variable prize winning device is closed and then opened again. . This is known as V continuation in a pachinko machine with a specific area called a V zone.

[0005]

However, in the conventional pachinko gaming machine provided with the above-mentioned variable winning device, especially when a condition of V continuation is given, a plurality of pachinko machines provided in the variable winning device are required. Since one of the three winning ports (for example, the central winning port) is set as the specific area (V zone), it is necessary to detect the hit ball entering the V zone separately from the winning balls to other winning ports. is there. Therefore, in addition to the detector that detects a winning ball that has won a winning opening other than the V zone in the variable winning device, a V zone winning ball detector that detects a winning ball that has entered the V zone is provided. The structure was complicated. In order to avoid this, it is conceivable to provide the V zone in a part different from the variable winning device,
This results in an increase in the prize area, and a space for the prize must be provided on the game board, which is not preferable in designing the game board.

Accordingly, an object of the present invention is to provide a pachinko gaming machine equipped with the above-mentioned variable prize apparatus, which is provided with a detector for detecting a prize ball entering a V zone in the variable prize apparatus, or a variable prize apparatus. It is an object of the present invention to provide a pachinko gaming machine having a function capable of determining whether or not the V continuation condition has been achieved without complicating the structure.

[0007]

SUMMARY OF THE INVENTION According to the present invention, there is provided a variable winning device capable of converting between an open state advantageous to a player and a closed state disadvantageous to a player, and detecting a winning ball won in the variable winning device. A prize sphere detector that generates a detection signal, and determines whether or not the prize sphere detector has generated a detection signal within a specific time that appears at a predetermined time interval. When the predetermined winning condition is achieved with the variable winning device being closed and the variable winning device being generated, the variable winning device is converted to the open state for a certain period of time, and the determining device determines during the conversion driving. And a drive control means for performing the operation of converting the variable winning device to the open state when the signal is generated, after the operation is completed, and setting the ratio of the length of the specific time to the time interval to 1: 2. It is characterized by having done.

[0008]

In the pachinko gaming machine of the present invention, the variable winning device is opened when a predetermined game condition is achieved, for example, when a hit ball wins a specific winning opening. Not only (opening) but also a repetitive opening / closing operation of opening and closing for a predetermined time and then opening again. When a hit ball wins the variable winning device in the opened state, the winning ball detector generates a detection signal.

During the opening operation described above, the winning area in the variable winning device becomes a V zone for a predetermined time, and functions as a normal winning area except for the specific time. In other words, even if the variable winning device is in the above-described opened state and the hit ball wins the variable winning device, a normal winning will be achieved if it is outside the specified time, and the V continuation condition will not be achieved. Accordingly, the winning area provided in the variable winning device is used as it is as a V zone. Then, when a hit ball wins in the variable winning device within a specific time, the determination means generates a determination signal in accordance with the detection signal generated by the above-described winning ball detector. Based on this determination signal, the drive control means performs this operation again after the operation of converting and driving the variable winning device to the open state as described above (becomes the V continuation state).

On the other hand, in the conventional variable winning device, as described above, a plurality (for example, three) of winning ports are provided inside, and one of them (for example, the central winning port) is set as the V zone. On the other hand, in the present invention, only one winning opening is provided in the variable winning device, and it can be used for both the V zone and the other winning opening. That is, in addition to simplifying the structure of the variable winning device, it is possible to use a detector for detecting a winning ball in the variable winning device as it is as a winning ball detector for the V zone. It only needs an individual.

Further, according to the present invention, the ratio of the length of a specific time in which one winning opening or a winning area is a V zone in the variable winning device to a time interval in which it appears is set to 1: 2. Compared to the case where one of the three winning ports provided in the conventional variable winning device is a V zone,
The probability that the V continuation condition is achieved by the winning of the hit ball does not change. Therefore, instead of the variable winning device having three winning ports, the variable winning device having one winning port can be installed as it is, and there is no need to perform nail adjustment on the game board surface with the installation. .

D) and the indicators 23L and 23R composed of
Inside the lower part of the front part 21, a cylindrical reel 25 is formed by arranging a part of its surface so as to appear in the large window 24. The reel 25 is driven to rotate in one direction by a reel drive unit 26 driven by a pulse motor with its center axis placed horizontally as a fulcrum. As shown in FIG. A sheet 27 on which ten symbols are printed is mounted. When the rotation of the reel 25 is stopped, one of the symbols of the sheet 27 wound on the peripheral surface of the reel driving unit 26 is the same as the rotary reel driving mechanism provided in the conventional pachinko machine. It has a function of positioning the reel 25 so as to fit within the window 24.

Next, as shown in FIG. 4, in the variable winning device 7, a plate 33 of substantially the same shape is openably and closably mounted on the front side of a horizontally long rectangular opening 32 formed on a trapezoidal front plate 31. This is a so-called attacker formed by. A prize hole 34 is provided in the lower center of the opening 32 of the attacker, and a prize ball detector 35 for detecting a hit ball entering the pit and generating a detection signal is provided. As the detector 35, a magnetic sensor that detects the passage of a pachinko ball by a change in a magnetic field is preferably used, but other detection means, for example, a microswitch, an optical sensor, an ultrasonic sensor, or the like may be used. On the other hand, a lamp 36 is disposed as a display that lights up for a specific time, as described later, in a portion corresponding to the winning opening 34 of the attacker (in this case, right above the winning opening 34).

The plate 33 is driven to open and close by a drive mechanism using a motor 37 as a drive source mounted on the back surface of the front plate 31. In detail, the plate 33 is normally closed as shown in FIG. 4 to close the winning opening 34. However, when the motor 37 rotates in one direction in response to an attacker opening signal described later, the closed state of FIG. To the open position as described above to enable the winning in the winning opening 34, that is, to set the attacker to an open state advantageous to the player. When the motor 37 is rotated in the reverse direction in this state, the plate 33
To return to the closed state.

The variable display device 6 and the variable winning device 7 described above.
Is controlled by the control means 40 shown in FIG. This control means 40 is provided with the above-mentioned specific winning opening 5L, 5R or 5C.
The signals from the special winning ball detector 8, the stop switch 15 described above, and the winning ball detector 35 of the variable winning device (attacker) 7 installed at the position where the hit ball that has won the game are detected are input. , The 7-segment displays 23L and 23R of the variable display device 6 and the rotating reel drive unit 26
And a function of outputting a signal for controlling the operation of the drive motor 37 of the variable winning device 7 and a signal for controlling lighting of the lamp 36 of the variable winning device 7.

The control means 40 comprises the following components.

The seven-segment displays 23L and 23R and the rotating reel drive unit 26 are started in response to the detection signal from the specific winning ball detector 8, and when a predetermined time has elapsed thereafter or in response to a stop signal from the stop switch 15. At this time, the 7-segment displays 23L and 23R and the rotating reel drive unit 26 are stopped at any one of the display patterns, and a specific display pattern (for example, the LED display window 22) is used.
L, 22R and the numbers and symbols appearing in the reel display window 24 are both stopped at "7" (at this time, a predetermined game condition for converting the variable winning device to the open state is achieved). A variable display control unit 41 for outputting an attacker opening signal for opening the attacker plate 33 for a predetermined time; and lighting the attacker lamp 36 in response to a specific time signal output from the control unit 41 for a specific time set in advance. A lamp drive circuit 42 for causing the attacker to determine whether or not the winning ball detector 35 of the attacker has generated a detection signal while the lamp drive circuit 42 is lighting the lamp 36 (within a specific time); A judgment circuit 43 for outputting a judgment signal serving as an attacker opening signal for opening the plate 33 of the attacker for a predetermined time; and a judgment signal (attacker opening signal) from the judgment circuit 43. A delay circuit 44 for delaying a fixed time counts the number of winning balls to the winning opening 34 based on the detection signal from the winning ball detector 35 of the attacker, and when the number reaches a certain value (for example, 10), A counter 45 for outputting a count signal serving as an attacker closing signal for closing the plate 33 even if the opening time of the attacker does not reach the above-mentioned fixed time, and the opening of the attacker from the variable display controller 41 or the delay circuit 44. In response to the signal, a signal for driving the motor 37 in the direction in which the plate 33 is opened is output.
A motor drive circuit 46 for outputting a signal for driving the motor 37 in the direction to close the plate 33 in response to the count signal (attacker closing signal) from

In the embodiment, the variable display control section 41 and the motor drive circuit 46 constitute drive control means in the present invention.

In the above configuration, the lamp driving circuit 42
Outputs a drive signal that repeats turning on and off at a constant period (for example, 3 seconds) as shown in FIG. In this case, the lighting time of the lamp 36 is a specific time (for example, one second) preset by the variable display control unit 41, and during this time, the winning port 34 of the attacker is a V zone that provides the above-described V continuation condition. . This specific time appears repeatedly at preset time intervals. In FIG. 7, since the period is 3 seconds and the specific time is 1 second, the time interval at which the specific time appears repeatedly is 2 seconds. As described above, the length of the specific time and the time interval at which the specific time appears can be arbitrarily determined. However, if the time ratio of turning on and off the lamp 36 is 1: 2 as shown in FIG.
The probability of V continuation is the same as the case where three winning ports are provided in the attacker and one of them is set as the V zone.

In the control means 40, a delay circuit 44
Is provided for the following reason. That is, in the attacker of the embodiment, the opening of the plate 33 ends when a certain period of time elapses or when the number of winning balls to the winning opening 34 reaches a certain value. When the V continuation condition is achieved by hitting the winning opening 34 with a hit ball, the plate 33 is once closed and then reopened after a predetermined time.
Set to 0.8 seconds. For this reason, it is necessary to delay the attacker opening signal for continuation of V output from the determination circuit 43 for the same time (for example, 0.8 seconds) and to send it to the motor drive circuit 46.
Is provided.

The control means 40 is configured as described above, and its constituent elements 41 to 46 include a microprocessor (C
PU) can be integrated into a single integrated circuit (IC), and the above specific time and other times can be arbitrarily set by a program.

Since the illustrated embodiment is configured as described above, its operation is as follows.

First, in the normal game state, the variable display 6
Has its display fixed to an arbitrary display pattern, while the variable winning device 7 has the plate 33 closed and the winning opening 34
And is in a closed state disadvantageous to the player.

In this state, the special winning openings 5L, 5R and 5
When a hit ball enters any of C, the specific winning ball detector 8 outputs a detection signal. As a result, the variable display control unit 41 of the control means 40 controls the 7-segment displays 23L and 23R.
Then, the rotating reel drive unit 26 is started, and the numbers and pictures appearing in the display window of the variable display unit 6 change, so that the player presses the stop switch 15 aiming at a specific display pattern. When the stop switch 15 is pressed, at a timing corresponding to a stop signal from the stop switch 15, or when a predetermined time has elapsed without the stop switch 15 being pressed, the 7-segment displays 23L, 23R and the rotating reel drive are driven. The unit 26 stops at one of the display patterns.

When the display mode at the time of the stop is a specific pattern, a game condition for converting the variable winning device to the open state is achieved, and the player plays the attacker for a predetermined time according to the pattern. An attacker opening signal for providing a state advantageous to the above is sent from the variable display controller 41 to the motor driving circuit 46, and the motor 37 is driven to open the plate 33 as shown in FIG. As a result, the hit ball can win the winning opening 34 of the attacker, and the winning ball detector 35 outputs a detection signal for each winning, increases the count value of the counter 45 by one, and pays out the known winning ball. A predetermined number of prize balls are paid out to the upper plate 12 by the mechanism.

On the other hand, the lamp 36 of the attacker repeats lighting and extinguishing as shown in FIG. 7 by the output from the lamp driving circuit 42 while the plate 33 is open, but wins during the lighting time (specific time). The mouth 34 is a V zone. Therefore, while the lamp 36 is on, the hit ball is
When entering, the determination circuit 43 outputs a determination signal serving as an attacker opening signal for continuing V. This determination signal is sent to the motor drive circuit 46 after being delayed for a predetermined time by the delay circuit 44. For this reason, the attacker plate 33 is once closed from the opened state and then returned to the opened state, and the state advantageous to the player continues.

When a certain number of hit balls are won in the winning opening 34 of the attacker in the opened state and the counter 45 counts up, a count signal serving as an attacker closing signal is output. In response to the count signal, the motor drive circuit 46
Drives the motor 37 in the opposite direction to when the plate is opened,
The plate 33 is returned to the closed state of FIG.

As described above, in the embodiment, the winning opening 34 is set to the V zone for a specific time in order to give a V continuation condition for performing the operation again after the operation of opening the attacker under the predetermined condition. During this time, the lamp 36 is turned on so that the player can recognize that the winning opening 34 is in the V zone.

Although the illustrated embodiment has been described above,
The present invention is not limited to this.

For example, the game condition for driving the variable winning device to be changed to the open state is not limited to the condition that the display mode when the variable display of the variable display device 6 of the embodiment is stopped is a specific pattern. It can be arbitrarily determined, such as winning in a winning area. The operation of converting and driving the variable winning device to the open state is not limited to the opening operation in which the plate is kept open in the embodiment, but may be a repeated opening and closing operation in which the plate is opened and closed again for a predetermined time.

The prize port set as the V zone is not limited to the variable prize apparatus, but may be an arbitrary prize area on the game board. The variable prize apparatus may be a tulip or any other variable prize device not limited to a so-called attacker. .

Further, in the embodiment, a lamp is used as an indicator for indicating that the winning opening of the variable winning device is in the V zone. Instead, a 7-segment LED is used.
Can be used. In that case, when the LED displays a specific number, for example, "7", the winning opening is set to the V zone. If it is not necessary for the player to recognize the V zone, the display may be omitted.

[0036]

As described above, according to the present invention, the prize area in the variable prize apparatus is set to the V zone for a predetermined time, so that only one prize is provided in the variable prize apparatus. It is sufficient to provide a mouth or a prize area, and the structure of the variable prize apparatus is simplified, and a detector for detecting a prize ball in the variable prize apparatus can be used as it is as a V zone prize ball detector. That is, since both the function of detecting the winning ball and the function of detecting the V continuation condition are achieved by one winning ball detector, there is no need to provide a separate detector for detecting the winning ball in the V zone. It is structurally more advantageous than the pachinko gaming machines and maintenance is easy.

Also, by setting the ratio of the length of a specific time in which one winning opening or a winning area is a V zone in the variable winning device to a time interval in which it appears to 1: 2,
Compared with the case where one of the three winning ports provided in the conventional variable winning device is set to the V zone, the probability that the condition of V continuation is achieved by the winning of the hit ball does not change.
A variable winning device having one winning port can be directly installed in the same place as the conventional variable winning device.

Further, in a conventional pachinko game machine,
Since the V zone in the variable prize apparatus and the other prize areas are provided separately, when the variable prize apparatus is in the open state, the player performs a hitting operation to win a prize in the V zone. According to the present invention, since the prize area and the V zone in the variable prize apparatus are at a common position, that is, at the same place,
The hitting operation of aiming only at the zone is not required, and even a beginner can enjoy the V-continuous game.
