2. Description of the Related Art In a so-called third-type pachinko machine, when a game ball is awarded at a starting port and a result of a lottery performed in response to the winning is displayed as a slot on a normal symbol display device, a normal electric motor is used. The opening / closing member of the accessory is opened, and when the game ball winning the opened accessory passes through the specific area, a big hit state (right generation state) is established. In this state, when a game ball is won in the third-type starting port, the large winning port is controlled to be opened and closed in a predetermined pattern, and a game state advantageous to the player is established.

In this kind of conventional pachinko machine, the character opening time change symbol is provided, and when the game ball passes through a specific area, the right is generated and the opening time change symbol is changed. When a symbol stops at a specific symbol, the opening time is extended for the next big hit, and a large hit is generated in a loop until the opening time change symbol stops at a non-specific symbol. (See Japanese Patent Application Laid-Open No. 10-127876).

However, in such a conventional pachinko machine, this kind of pachinko machine usually has the image that there are many payouts.
Depending on the determination based on the opening time change symbol, the big hit was stopped only once, which could betray the player's expectation for a large number of balls to be played. Further, since the opening time change symbol always changes when the game ball passes through the specific area, the simple game content is such that the same game is repeated at every big hit.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a game machine of this type which can give a player a sufficient sense of expectation of the game. Aim.

In order to achieve the above-mentioned object, when predetermined conditions are satisfied, it is possible to win a game ball to the accessory, and when the winning ball passes through a specific area, the game ball is played. In a gaming machine capable of generating a gaming state advantageous to a player, a specific area passage detecting means for detecting the passage of a game ball to the specific area and a time for enabling a prize of the game ball to the accessory are changed An opening time change determination detecting means for detecting a game ball passing through a predetermined place is provided separately as an opportunity for performing a lottery of whether or not to perform the lottery.

[0005] Therefore, the number of big hits and the number of lotteries for extending the open time can be made different from each other, so that a player can have a sufficient sense of game expectation in this type of gaming machine.

Further, based on the detection results of the specific area passage detecting means and the opening time change detecting means, the opening time of the opening / closing member for enabling the winning of the game ball to the accessory is controlled. Control means, the control means, when the characteristic area passage detection means detects the passage of the game ball to the specific area, the opening time of the opening time if a game state advantageous to the player occurs during the normal opening time On the other hand, if a game state advantageous to the player is generated when the opening time is extended, whether the opening time is extended or not is determined in accordance with the detection of the game ball by the opening time change determination detecting means. It may be characterized in that it is means for performing a lottery.

[0007] Furthermore, the winning sphere detected by the characteristic area passage detecting means to pass to the specific area is replaced with a ball path provided with the opening time change detecting means or a second ball different from this. A distribution mechanism for distributing to any of the passages may be provided.

[0008] Such control can be realized by recording the control procedure on a computer-readable recording medium, and reading and executing the display control procedure recorded on the recording medium by the computer. Examples of such a recording medium include a semiconductor recording medium such as a ROM and a semiconductor IC, an optical recording medium such as a DVDROM and a CDROM, a magnetic recording medium such as a flexible disk, and a magneto-optical recording medium such as an MO.

Further, an effect device 460 including a lamp, a sound effect generating device for outputting a sound effect, and the like (not shown) is connected, and the main control unit 200 can transmit a control signal for controlling each of these devices.

The main control unit 200 is connected to a power supply circuit 710 for supplying power and a reset circuit 700 for outputting a reset signal every predetermined time. A pulse signal generated by the periodic timer counter is input from the control unit 200, and a monitor signal for monitoring a current supply state from the power supply circuit 710 is input.

Next, a main random number generation counter used by the gaming machine according to the embodiment of the present invention will be described with reference to FIG. Various random numbers are counted up one by one in a predetermined cycle (for example, 4 msec) sequentially from the value “0” until reaching the upper limit value, and when the count value exceeds the upper limit value, the initial value “ It is generated by using a so-called infinite loop counter which is cleared to "0" and the counting operation is repeated.
The main control unit 200 is formed in the AM 202 and controls the counting operation.

As shown in FIG. 4, the main count is a random number counter for hit determination (count value: 0 to 23).

The hit determination counter 500 is a counter used for performing a lottery in accordance with a prize of a game ball to the normal symbol starting port 112. When the counter value is "7", a slot is displayed. Otherwise, the slot display state is not generated. Thus, assuming that the total count value is "240", in the normal gaming state, the slotted display state is generated with a probability of 1/240.

The hit symbol selection random number counter 504 is a counter used to select a symbol to be used when the same symbol is stopped and displayed in the display area of the ordinary symbol display device 110 so that, for example, three identical symbols are aligned in a line. When the counter value is randomly selected, a symbol is displayed on the ordinary symbol display device 110 in a symbol pattern corresponding to the selected counter value.

An off-left symbol selection random number counter 501, an off-center symbol selection random number counter 502, and an off-right symbol selection random number counter 503 are displayed on the normal symbol display device 110 when the double-eye display state does not occur. This counter is used to select a symbol to be stopped and displayed in the area. When these counter values are randomly selected, the left, middle, and right symbols corresponding to the selected counter value are displayed on the ordinary symbol display device 110.

Next, the control operation performed by the main control unit 200 will be described with reference to the flowchart of FIG. Here, a very general operation of this type of gaming machine will be described, and thereafter, an operation of a main part of the present invention will be described to facilitate understanding. FIG. 3 is a flowchart for explaining the gaming operation of the gaming machine. The series of processing shown in FIG. 3 is executed by the main control unit 200.
The process is executed from step S100, which is the first step, with a reset signal supplied every predetermined time (for example, 4 msec) from 00 as a trigger.

First, when the power supply circuit 710 is activated by a power switch (not shown), the main control unit 200 is activated. However, if the first processing is executed after the power is turned on, the RAM 202 is reset. A clear process is executed to clear at least a predetermined area including the counter area 216. At this time, the main control unit 200 sets the second starter rotating plate rotating motor 430
Then, the drive of the rotating plate rotating motor 440 for the ordinary electric accessory is started. At this time, the distribution control motor 450 is driven so as to set the ball passage A.

First, the main control unit 200 determines whether or not the game ball has won the normal symbol start port 112 based on the detection result of the start winning switch 310, and when it is determined that the game ball has won (Yes in step S100). ) Includes step S10
Then, if it is determined that no prize has been won (No in step S100), the process proceeds to step S118.

In step S102, a lottery of the hit determination random number counter 500 is performed, and the flow shifts to step S104, where it is determined whether or not a hit is made, in other words, whether or not to display a double-row display. When Displaying the Slotted Eyes (Step S104
(Yes in step S104), the process proceeds to step S106. Otherwise (No in step S104), the process proceeds to step S106.
Move to 108. In step S108, the counter values of the off-left symbol selection random number counter, the off-center symbol selection random number counter, and the off-right symbol selection random number counter from the random number counters 501 to 503 are grasped, and a symbol corresponding to this is displayed as a normal symbol. Display on the device 110 and step S1
Move to 18.

In step S106, the counter value of the winning symbol selection random number counter 504 is grasped, and the corresponding zigzag pattern, for example, "777" is displayed on the ordinary symbol display device 110.
And the process proceeds to step S110. In step S108 and step S106, various display effects are performed until the drive of the effect device is controlled by an appropriate control pattern or a stop symbol is displayed.

Then, in step S110, the motor-operated opening / closing members 420a and 132b are controlled by driving the motors 420a and 420b for opening / closing the ordinary electric accessory, and the ordinary electric accessory 130 is set to an open state in which a prize can be won. Next, in this state, it is determined whether or not any of the winning game balls has passed a specific area, and if there is a passing game ball (Yes in step S112), the process proceeds to step S114. On the other hand, when there is no passed game ball (step S
If No in step 112, the process proceeds to step S118. Therefore, when the process proceeds to step S114, the gaming machine is in a big hit state (right generation state).

Next, in step S114, when a game ball wins in the third type starting port 114 and the game ball supplied to the ball distribution tub (not shown) through the hole 117 is detected by a sensor (not shown) (step S114). Yes), the process proceeds to step S116, and in other cases (step S114)
NO), the process proceeds to step S118. Step S
At 116, the large winning opening solenoid 410 is drive-controlled to open and close the opening / closing member 121 of the special winning opening device 120 for a predetermined period of time so that the game ball can easily win (a state advantageous to the player).

In step S118, a random number update is performed to increase the counter value of each counter as shown in FIG. 4, for example, by one. This random number update is repeatedly executed until the next reset signal is supplied.

(Main parts of the present invention) FIG. 6 is a schematic front view of the internal structure of the ordinary electric accessory 130 according to the embodiment of the present invention, and FIG. 7 is a schematic side view of the upper part thereof. In FIG. 7, only one storage unit 601 is illustrated for easy understanding, and other storage units are not illustrated.

At the center of the disk-shaped rotating plate 600, a rotating shaft 4 of a long axis of a motor 440 for rotating a rotating plate for ordinary electric accessory is provided.
41 is fixed, and the rotating plate 600 is rotated by the rotation of the rotating shaft 441 of the motor 440 for rotating the rotating plate of the ordinary electric accessory.
Is rotated. On the rotating plate 600, a disc-shaped guide member 680 having the same diameter is disposed with a very small gap provided between the rotating plate 600 and the rotating plate 600. Regardless, it is fixed by a fixing member (not shown) so as not to rotate.

Further, storage portions 601 (601 a to 601 h) are provided on the circumferential portion of the rotating plate 600 at appropriate intervals. When the storage unit 601 comes to the lowest point when viewed from the front, it is possible to receive the game ball P which is awarded by the ordinary electric accessory 130 and flows down. The storage portion 601 is provided with a slope 601 (see FIG. 7) so as to guide the received game ball from the front side to the back side, and the game ball P is provided at the end point of the slope. A hole 603 (see FIG. 7) for discharging to the side is formed.

A hole 682 is formed on the front left side of the guide member 680, and the ball passage 67 is formed in the hole 682.
0 is linked. Therefore, the received game ball P is configured to be moved with the rotation of the rotary plate 600 while being in contact with the rotary plate 600, and when the game ball P reaches a position corresponding to the hole 682, The game ball P is configured to be discharged from the storage portion 621 to the ball passage 670 through the hole 682.

Further, the holding unit 601 corresponding to a specific winning
A reflector 620 is provided outside e, while a specific area passage detection sensor 340 for detecting the same is also provided. The specific area passage detection sensor 340 uses the reflector 62
When the reflected light of the light irradiated to 0 is received, a signal to that effect is output. Further, a ball passage detection sensor 350 for detecting the passage of the game ball P is provided in the ball passage 670. Therefore, when it is determined that the ball is detected by the ball passage detection sensor 350 immediately after the main control unit 200 detects the output signal of the specific area passage detection sensor 340, the prize in the specific area is performed. Figure out.

The ball passage 700 is divided into a ball passage A and a ball passage B at an intermediate portion thereof, and the moving member 680 fixed to the rotating shaft 681 of the distribution control motor 450 is moved by the motor 450. By controlling the movement of the ball, the ball path of the game ball P flowing down in the ball path 700 can be changed. In the example shown in FIG. 6, the moving member is moved to guide the game ball P to the ball passage A. However, if the distribution control motor 450 is drive-controlled so that the rotating shaft 681 rotates clockwise. The moving member 680 is moved as shown by a dotted line, and this time, the game ball P is guided to the ball passage B. Further, an opening time change determination switch 330 is provided on the ball passage B side.

(Example of Operation) As shown in FIG. 8, first, in step S800, immediately after the main control unit 200 detects the output signal of the specific area passage detection sensor 340, ball detection by the ball passage detection sensor 350 is performed. It is determined whether or not it has been determined, that is, whether or not a prize has been won in the specific area. When it is determined that the winning is not performed (N
In o), the process ends. On the other hand, when it is determined that the winning is performed (Yes), the process proceeds to step S802, and the opening time of the opening / closing members 132a and 132b is currently the normal time or It is determined whether it is a specific time.

If the opening time of the opening / closing members 132a and 132b is normal (Yes in step S802), the process proceeds to step S804. On the other hand, in other cases, the opening time of the opening / closing members 132a and 132b is specified (step S802). In S802, the process proceeds to step S806. In step S804, the main control unit 200 controls the drive of the distribution control motor 450 to set the ball path of the game ball to A, and after the big hit game ends, the opening / closing member 132
The opening times of a and 132b are set to be longer than usual as a specific time. Then, the main control unit 200 drives and controls the distribution control motor 450 so that the ball passage is set to B.

On the other hand, in step S806, it is determined whether or not the opening time change determination switch 330 has been turned ON upon detecting a game ball. If it has been turned on (Yes), the process moves to step S808, and if it has not been turned on, it enters the wait state in step S806. The main control unit 200 performs the lottery operation immediately after the end of the big hit game.

In steps S 808 and S 810, the main control unit 200 controls the distribution control motor 450
Is controlled to drive the ball path of the game ball as B, so that a random number for changing the opening time is selected. More specifically, the counter value of the opening time change random number counter 505 is grasped,
It is determined whether or not this is a specific value. If the value is a specific value (Yes in step S810), it is determined as “hit” in step S8.
12, and after the big hit game is over, the opening / closing member 132
The opening times of a and 132b are set to be longer than usual as a specific time. At this time, in order to keep the ball passage B, the drive of the distribution control motor 450 is not controlled.

On the other hand, if it is not the specific value (step S81)
In the case of No), the process proceeds to step S814 as “disengagement”, and the opening / closing members 132a, 132 at the time of the next right generation
The opening time of b is returned to normal, and then the drive of the distribution control motor 450 is controlled in step S816 to set the ball path of the game ball to A.

FIG. 9 is a specific explanatory diagram of this operation.
When the opening time of the opening / closing members 132a, 132b of the ordinary electric accessory 130 is normal, the ball passage A is set by the sorting control, and the opening / closing members 132a,
The opening time of 132b is extended (). by this,
The next big hit will surely occur early. When the next big hit occurs, a ball passage B is set this time by the sorting control, and a lottery is performed to determine whether or not the opening time is extended ().

This lottery is performed, and after the big hit game after the "hit" is completed, distribution control is performed so as to be the ball path B and whether or not the opening time is extended for each big hit is determined. (,). FIG.
As shown in (2), a lottery is performed to determine whether or not to extend the open time.

If the lottery result indicating whether or not the opening time is to be extended is "out", the distribution control is performed so as to be route A (), so that the lottery result becomes "hit" and continues. As long as it is, the ball passage becomes the ball passage B. Therefore, the next big hit occurs surely at an early stage, and the subsequent big hit depends on the result of the opening time change lottery.

As described above, according to the embodiment of the present invention, the specific area passage detection sensor 340 and the ball path detection sensor 350 for detecting the passage of the game ball to the specific area.
(Specific area passage detection means) and a game passing through the ball passage B as an opportunity for performing a lottery to determine whether or not to change the time during which the game ball can be awarded to the ordinary electric accessory 130. Since the opening time change determination switch 330 (opening time change determination detecting means) for detecting a ball is provided separately, the number of jackpots and the number of lotteries for extending the opening time can be made different from each other. In the gaming machine, the player can have a sufficient sense of expectation of the game.

When the specific area passage detection sensor 340 and the ball passage detection sensor 350 (characteristic area passage detection means) detect the passage of the game ball to the specific area, the main control unit 200 sets the right from the normal opening time. If the right is generated from the extension of the opening time, the opening time change determination switch 330 is extended.
In accordance with the detection of the game ball by the (opening time change determination detecting means), the lottery is performed to determine whether or not the opening time is to be extended. On the other hand, since the opening time is extended in accordance with the lottery result, there is no fear that the opening time extending function is operated unnecessarily.

Further, the winning sphere detected to have passed to the specific area is sent to the ball passage B provided with an opening time change determination switch 330 (opening time change determination detecting means) or another ball path B. Since a distribution mechanism for distributing the ball to any one of the ball paths A (second ball paths) is provided, this type of gaming machine can be realized by providing a mechanism having a simple configuration.

Although the embodiments of the present invention have been described above, various modifications and changes can be made to the above embodiments without departing from the spirit of the present invention. For example, the distribution mechanism is changed to another one, and the normal electric accessory 130 is used.
Is different from that of the first embodiment, and a symbol display that fluctuates and displays according to a random number for determining opening time change is given.

As described above, according to the present invention, when a predetermined condition is satisfied, it is possible to win a game ball to an accessory, and when the winning ball passes through a specific area, In a gaming machine capable of generating a gaming state that is advantageous for a player, an effect is obtained in which the player can have a sufficient sense of expectation of the game.
