2. Description of the Related Art In this type of ball game machine, one generally known in the art has been disclosed in, for example, Japanese Patent Laid-Open No. 58-58-58.
There is a pachinko machine disclosed in Japanese Patent No. 112571. In this pachinko machine, a pair of left and right movable members (movable pieces) are axially attached to a variable winning ball device (variable winning device) so as to face each other, and the driving force of an electromagnetic solenoid as a driving source corresponding to each movable member is driven. By transmitting via a link mechanism as a transmission mechanism, each movable member is rotated within a predetermined range, and the variable winning ball device is changed to a state advantageous to the player and a state disadvantageous to the player. Has been done.

[0003]

By the way, in this type of ball game machine, it is desirable that the operating conditions are the same on the left and right, such that the operating timings of the movable members are synchronized on the left and right. In order to meet such a demand, it is necessary to simultaneously operate the movable member driving drive sources corresponding to the pair of left and right movable members and appropriately transmit the driving force of each movable member driving drive source to the movable members. is there. However, in the above-described conventional pachinko machine, the variable winning ball device provided with the movable member and the movable member drive source for supplying the driving force to the movable member can be separately attached to the pachinko machine. ing. Therefore, when the pachinko machine is assembled, the variable winning ball device and the movable member drive source are attached to the pachinko machine in a state where the relative positional relationship between the movable member and the movable member drive source is not appropriate. There is a risk that In a state where the positional relationship between the movable member and the movable member driving drive source is not appropriate, even if the operations of the two movable member driving drive sources are synchronized, the driving force of the movable member driving drive source is transmitted to the driving force transmission mechanism. In the process of transmitting to the movable member via the appropriate drive force, the driving force is not properly transmitted, it is difficult to synchronize the operation timing of the movable member, and the movable member does not fluctuate with an appropriate amount of movement. May occur.

The present invention has been conceived in view of the above circumstances, and an object thereof is to supply a driving force to a movable member as much as possible to simultaneously fluctuate the left and right movable members in the opening direction and the closing direction. An object of the present invention is to provide a ball game machine that can be accurately and easily mounted in a state in which the means for supplying a driving force can operate properly.

[0005]

[Means for Solving the Problems] Having a pair of left and right movable members, both movable members being moved in the opening direction at the same time results in a first state advantageous to the player, and the both movable members are closed at the same time. A ball-and-ball game machine including a variable winning ball device that is in a second state that is disadvantageous to the player by being changed in a direction, the first and the first balls being provided in accordance with each of the left and right movable members. A second movable member drive source, a drive force transmission mechanism for transmitting the drive force of the first and second movable member drive sources to the left and right movable members, and the first and second movable members. The first and second movable member drive sources are integrally provided in the variable winning ball device, and an operation synchronization unit that simultaneously operates the member drive sources.

[0006]

According to the present invention, the drive source for driving the first and second movable members is provided integrally with the variable winning ball device in accordance with each of the pair of left and right movable members. The driving sources for driving the first and second movable members are simultaneously operated by the action of the operation synchronizing means, and the respective driving forces are transmitted to the pair of left and right movable members by the driving force transmission mechanism so that both the movable members are simultaneously moved. fluctuate. At the time of assembling the ball game machine, since the variable winning ball device having a pair of left and right movable members and the driving source for driving the first and second movable members are integrally attached, the series of operations described above is performed. For this reason, the drive source for driving the movable member is attached to the ball game machine in an appropriate state.

FIG. 7 is a game control circuit diagram of an embodiment of the present invention. The game control circuit of this embodiment includes a prize-ball detecting means 41, a prize-ball detector 42, and a drive control circuit 50. The drive control circuit 50 includes a first signal generation circuit 51, which is an example of first signal generation means, an alternate drive control circuit 52, which is an example of alternate drive control means, and a second signal generation circuit, which is an example of second signal generation means.

In the period during which the variable prize ball detector 20 is output, the variable prize ball device 20 is closed for a certain period of time after the variable prize ball device 20 is closed. A signal for repeatedly driving alternately within a certain number of times of opening and closing or a certain period of time is generated. The alternate drive control circuit 52 includes the first or second signal generation circuit 5
In response to the outputs of 1, 53, the variable winning ball device 20 is alternately opened and closed.

FIG. 8 is a time chart for explaining the operation of FIG. 7, particularly when a specific condition is reached while the variable winning ball device 20 is being opened in accordance with the passing ball to the passing area 2c. Show.

Prior to the description of the operation of this embodiment, an outline of the driving state of the pachinko machine 10 of this embodiment will be briefly described. When the hit ball has passed through the passage areas 2a, 2b, the first and second opening / closing blade pieces 22a, 22a of the variable winning ball device 20,
22b, 23a, 23b are opened / closed in a mode in which a relatively small game value is given (for example, opened / closed once, opened for 1 second to be closed, opened until one ball is won). When the driven-in ball passes through the passage area 2c, the first and second opening / closing blade pieces 22a, 22b, 23a, 23b are opened / closed in a state in which a relatively small game value is imparted (for example, only twice). Open and close, open for 2 seconds and close, open until two balls are won). This open / close wing piece 2
During the opening of 2a and 22b, the driving ball is the winning hole 21a.
When a prize is won, a special condition is established in which a special prize detector 42, which is an example of a special prize detecting means, detects and a relatively large game value is given. In this case, each opening / closing wing piece of the variable winning ball device 20 is opened / closed from that time (for example, opened / closed 18 times continuously, opened / closed 18 times or a predetermined number of times). It will be opened and closed until the earlier condition of winning the "10 etc." pachinko balls is achieved). Then, when a ball wins during the opening of each opening / closing blade piece, before the opening / closing drive reaches a fixed number n (for example, 18 times), the opening / closing drive is performed a fixed number of times again from that time. In this way, the repetition continuation condition in which a relatively large game value can be repeatedly given is satisfied for a fixed number of times m (for example, m = 8 times). Therefore, the opening / closing blades 22a to 22a are the most efficient.
In order to open / close 3b, the opening / closing operation is performed a fixed number of times n.
If the balls are made to win the prize hole 21a at the time of the second time, the opening / closing blade pieces 22a to 23b can be opened and closed only n × m times. On the other hand, in the case of the worst efficiency, that is, in the repeated opening and closing operations from the first round to the nth round, if there is a winning ball at the first time (that is, n = 1),
Only opening and closing drive is performed m times.

Next, with reference to FIGS. 1 to 8, the specific circuit configuration of FIG. 7 and its operation will be described.

First, a case where a hit ball passes through the passing area 2a or 2b, or a ball which passes through the passing areas 2a and 2b is led to the back surface of the game board 1 as a winning ball will be described. In the passing areas 2a and 2b, prize winning ball detectors 411 and 412, which are an example of passing ball detecting means, are provided in association with each other. Therefore, a winning ball detector (for example, 411) corresponding to the passing area where the ball has passed derives a detection output and supplies it to the holding circuit 511 via the OR gate 413. The holding circuit 511 stores and holds that there is a winning ball, and derives a high level until a reset signal is given from a reset pulse generation circuit 515 described later. The high level is given to the timer 512 and the drivers 522 and 523 through the OR gate 521. Timer 512
Operates in response to the rise of the output of the holding circuit 511, and clocks a predetermined fixed time (for example, 0.6 seconds). During the fixed time set by the timer 512, the drivers 522, 523 are operated by the corresponding solenoids 31a, 31
Energize b. Accordingly, the solenoid 31a attracts the plunger to rotate the lever 33a, and pushes the short side of the lever 34a downward. Therefore, the long side of the lever 34a rotates in the direction opposite to the center of the variable winning ball device 20. Accordingly, the sliding support member 235 slides to the left of the guide hole 211. By sliding the sliding support member 235,
Since the pin 234 of the opening / closing wing piece 23a moves leftward when viewed from the front, the pin 233 accordingly moves the pin 233.
Move diagonally upward along 3 As a result, the opening / closing wing piece 23a is opened as if the hand is widened. At the same time, the lever 35a moves along with the movement of the lever 34a, and the pin 224 of the opening / closing blade piece 22a is inserted into the guide hole 219.
Rotate diagonally downward along. Therefore, the open / close blade 22a is also opened. The OR gate 521, the drivers 522, 523 constitute an operation synchronizing means for simultaneously operating the driving sources for driving the first and second movable members.

When the solenoid 31b is energized,
The opening / closing blade pieces 22b, 23b on the right side are opened in the same manner as the opening operation of the opening / closing blade pieces 22a, 23a on the left side. When the timer 512 times up with a certain time delay, the time-up output is given to the AND gate 514 via the OR gate 513. And gate 514
, The output of the holding circuit 531 is inverted and applied, but at this time, it is activated because it is not in the detection state of the specific condition. Therefore, the AND gate 514 derives the high level and supplies it to the reset pulse generating circuit 515. The reset pulse generation circuit 515 derives a pulse having a minute time width as a reset pulse and resets the holding state of the holding circuit 511. As a result, the holding circuit 51
Since the output of 1 becomes low level, the drivers 522, 5
23 stops the energization of the solenoids 31a and 31b. In this way, when the driven ball passes through the passage areas 2a and 2b, each of the opening and closing blade pieces 22a to 23b is opened and closed only once.

Next, the operation when the hit ball passes through the passing area 2c or wins will be described. In this case, the winning ball detector 414 provided in association with the passage area 2c is shown in FIG.
The detection output as shown in (3) is derived and given to the holding circuit 516. The holding circuit 516 has a reset pulse generation circuit 515.
From winning prize detector 41 until reset pulse is given from
The fact that there is an output of 4 is stored and held, and a high level representing that state is derived. This high level is OR gate 5
24 to the AND gate 525. The output pulse of the frequency divider 526 is given to the AND gate 525 as the other input. The frequency divider 526 divides the output pulse of the clock oscillator 527. The frequency-divided pulse p1 provided from the frequency divider 526 to the AND gate 525 has a high level period of T1 (for example, 0.8 seconds) and a duty ratio of 50%. Therefore, the AND gate 525 derives the output pulse p1 of the frequency divider 526 and supplies it to the drivers 522 and 523 via the OR gate 521 while the output of the holding circuit 516 is at the high level. At the same time, the output of the holding circuit 516 is used as an activation signal for the display drive circuit 542 and the binary counter 51.
Given to 7. The display drive circuit 542 outputs the output pulse p2 of the frequency divider 526 during the period in which the activation signal is applied.
The light emitting diodes 27c and 27d are intermittently illuminated and displayed in synchronization with the cycle (higher than the frequency of p1), and the opening and closing blades 22a to 23b are opened and closed in a mode in which a relatively small game value is given. Inform you that you are inside.
The binary counter 517, when activated by the output of the holding circuit 516, outputs the output pulse p1 of the frequency divider 526.
Each time a pulse p1 'synchronized with is supplied, a counting operation is performed, a count-up output is derived in response to the application of the two pulses, and is supplied to the reset pulse generation circuit 515 via the OR gate 513 and the AND gate 514. Therefore, the reset pulse generation circuit 515 has a predetermined time Td (where T1 ≦ T1) from the rise of the pulse p1.
A reset pulse having a minute time width is derived with a delay of (Td ≦ 2T1) and applied to the holding circuit 516. In response, the holding circuit 516 releases the storage holding state and sets the output to the low level. As a result, the holding circuit 516 outputs a high level until the AND gate 525 derives the two pulses p1, so that the solenoids 31a and 31b are set to 2 levels.
It is energized intermittently only once. Therefore, each open / close wing piece 2
As for 2a to 23b, one opening time is a fixed time T1, and the opening and closing is driven only twice.

By the way, as described above, when the driving balls do not enter the winning hole 21a in a state where the opening and closing blade pieces 22a to 23b are driven to open and close once or twice.
The specific condition that a relatively large game value can be given is not established.

On the other hand, as described above, each opening / closing blade piece 22
When the hit ball wins the winning hole 21a during one or two opening operations of a to 23b, the specific condition is satisfied and the following operation is performed. That is, each ball receiving piece 22a-
When the driving ball wins the winning hole 21a during the opening of 23b,
The prize ball detector 42 detects it. Prize ball detector 42
The special condition detection output of is given to the holding circuit 531 and the differentiation circuit 532. Differentiating circuit 532
Derives a pulse of a minute time width by differentiating the special condition detection output at the rising edge. The output pulse of the differentiation circuit 531 is
The reset pulse is supplied to the n-ary counter 533 and the addition pulse is supplied to the m-ary counter 534. The n-ary counter 533 is activated while the output of the holding circuit 531 is at a high level, counts the pulse p1 ′ given from the frequency divider 526, counts up a fixed number n, and counts up, counting a fixed number. Even before the reset, the count value is reset in response to the application of the reset pulse. In other words, the n-ary counter 5
Reference numeral 33 indicates the variable winning ball device 20 a fixed number of times n or less as a game control state in which the variable winning ball device 20 can give a relatively large game value during the period of the first state in which the player is advantageous. In order to drive the opening and closing, the number of opening and closing is counted until a special prize ball is detected next, which is a fixed number n or a number equal to or less than the fixed number n. On the other hand, the m-adic counter 534 is used to open / close each opening / closing blade piece 22 of the variable winning ball device 20.
In the state in which a to 23b are repeatedly opened and closed, the number of times the driven-in ball has won the winning hole 21a, that is, the number of special balls is counted. The count value of the m-ary counter 534 is given to the prize state prohibition circuit 535. The prize state prohibition circuit 535 has a setting unit for setting the number of times that one pachinko machine 10 can keep repeating the game control state in which it can give a relatively large game value, and the count value of the m-ary counter 534. A comparator circuit for detecting that the set number m has been reached,
And a prohibition circuit for continuously deactivating the holding circuit 531 when the number of repetitions of the repetition continuation condition reaches m times.

Next, the operation in the case where a specific condition for giving a relatively large game value, which is a feature of the present invention, is satisfied will be described more specifically with reference to the time chart of FIG. In the time chart shown in FIG. 8, the special prize ball is detected for the first time in the state where each of the opening / closing blades of the variable winning ball device 20 is opened twice, the specific condition is satisfied, and the first advantageous state is given. And in the first advantageous state, n
(= 18) When the second prize is detected during the second opening period, the repeat continuation condition is satisfied, and the third prize is detected during the third opening period in the second advantageous state. Indicates. That is, the prize ball detector 42 is the winning hole 21.
When the special prize ball that won the first time in a is detected, the differentiation circuit 5
32 rises and differentiates it, and the differentiated pulse resets the n-ary counter 533 and advances the count value of the m-ary counter 534 by one. Then, the count value of the m-ary counter 534 is displayed on the segment display 26 via the decoder 543. At the same time, the holding circuit 531 derives a high level, activates the n-ary counter 533 and the display drive circuit 541, and further applies a high level to the AND gate 525 via the OR gate 524. The output of the holding circuit 531 is the AND gate 51.
Immobilize 4. In response, the AND gate 525 derives the output pulse p1 of the frequency divider 526 to output the OR gate 52.
1 to the drivers 522 and 523. The drivers 522 and 523 intermittently energize the corresponding solenoids 31a and 31b in synchronization with the cycle of the pulse p1. As a result, the open / close blades 22a to 23b of the winning ball device 20 are intermittently opened / closed. At this time,
The n-ary counter 533 counts p1 ′ synchronized with the pulse p1 and counts the number of times each opening / closing blade is driven to open / close in the first advantageous state. At this time, the display drive circuit 5
41 is in a game control state in which the light emitting diodes 27a and 27b are intermittently illuminated and displayed in synchronization with the frequency division pulse given from the frequency divider 526, and a relatively large game value can be given to the player. Let us know. The light emitting diodes 27a to 27d constitute a display device for displaying the first state of the variable winning ball device. Then, as described above, in order to inform the player that the game control state in which a relatively small game value can be given, the first display devices 27c and 27d display (light or blink). The second display device 2 at a position different from the first display devices 27c and 27d indicates that the game control state in which the relatively large game value can be given is entered.
It is displayed (lit or blinking) by 7a and 27b. Furthermore, the display that the game control state in which the relatively small game value can be given is entered is intermittently emitted and displayed in the first cycle synchronized with the cycle of the output pulse p2. Further, the display that the game control state in which the relatively large game value can be given is entered is intermittently emitted and displayed in the second cycle synchronized with the cycle of the output pulse p3 different from the first cycle. .

The first display device 27c, 27d and the second display device 27a, 27b are the same, and
You may make it change the light emission display mode, respectively.
Alternatively, the display cycle may be the same and only the positions of the first display device and the second display device may be different.

Fortunately, each of the open / close blades 22a-23
If there is no winning ball in the winning hole 21a by the time b is opened less than the maximum number n times, and there is a special prize ball during the nth opening period, the opening operation of the nth time is finished. The second advantageous operation is then performed. That is, when the prize ball detector 42 detects the second prize condition, the count value of the m-ary counter 534 becomes 2, and the count value "2".
Is displayed on the segment display 26 via the decoder 543, and the count value of the n-ary counter 533 is reset (= 0). At the same time, the differential pulse of the differentiating circuit 532 is given to the reset pulse generating circuit 515, and the reset pulse generating circuit 515 holds the holding circuit 5 for a minute time.
Reset 31. However, since the output time of the prize ball detector 42 is selected longer than the time width of the reset pulse, the holding circuit 531 holds the second advantageous state thereafter. As a result, the above operation is performed again.

Then, in the second advantageous state, during the third opening operation of the opening / closing blade, the driven-in ball is in the winning area 21.
When the player wins a, the third prize ball is detected. Therefore, in this case, in one advantageous state, each opening / closing wing piece is not repeatedly opened / closed a maximum number of times n, and the opening / closing operation is completed with a relatively small number of three times, and the third prize is given. Move to an advantageous state when a ball is detected.

Thereafter, in the same manner, each of the opening / closing blade pieces 22a-23 is formed.
During n times of opening / closing operation of b, the opening / closing drive is performed the number of times equal to or less than the maximum number (n) that can be driven to open / close in one advantageous state in response to the winning ball in the winning hole 21a, and then the next repetition. The drive is controlled so as to be in an advantageous state based on the continuation condition. Then, when the number of repeated times reaches a predetermined fixed number (m times), the prize state prohibition circuit 535 detects it and continuously derives a high level. Since this high level is given as the reset input of the holding circuit 531, the holding circuit 531 does not store and hold the detection of the special prize even after the output of the special prize detector 42. The special prize ball detector 42 constitutes a specific prize ball detecting means for detecting a prize ball that has won in a specific prize area. Note that the m-ary counter 534 may count the output when the variable winning ball device is in the first state again after winning the prize hole 21a. In addition, by the drive control circuit 50, based on the detection output of the passing ball detection means, the variable winning ball apparatus is driven to the first state, so that a relatively small game value can be imparted to the game control. However, in the game control state in which the relatively small game value can be given, the variable winning ball device is set to the first based on the fact that a predetermined specific condition is satisfied in association with the detection output of the specific condition detecting means. Is controlled in such a manner as to be able to give a relatively large game value by being driven to a state, and is predetermined in relation to the detection power of the specific winning ball detecting means in the game control state in which the relatively large game value can be given. Based on the established repeated continuation condition, the drive control for driving the variable winning ball device to the first state again so as to give the relatively large game value. Stage has been constructed. The drive control means temporarily stores the establishment of the repeated continuation condition, and then drives the variable winning ball device to the first state again based on the storage to give the relatively large game value. The game may be controlled as described above.

The drive control means composed of the drive control circuit 50 drives the variable winning ball device to the first state based on the detection output of the passing ball detection means to give a relatively small game value. While controlling the game so that you can
When the display device is displayed in the first display state, and the predetermined winning condition is established in association with the detection output of the specific condition detecting means, the variable winning ball device is set to the first position.
It includes a drive control display means for driving the display device to control the game so that a relatively large game value can be added and displaying the display device in the second display state.

As described above, the variable winning ball device 20 used in this embodiment is provided with two winning holes having a step on the upper and lower sides, and opening and closing blades are provided on the left and right sides of the two winning holes, respectively. Since the length of the ball receiving portion of the lower opening / closing wing piece is selected to be longer than the length of the ball receiving portion of the upper opening / closing wing piece, it is possible to win the driven-in ball into the winning hole 21b with an extremely high probability. , When the hit ball enters the winning hole 21a with a relatively low probability, there is an advantage that the game control state in which a relatively large game value can be given can be repeated. As a result, there is an advantage that the player can obtain a prize ball with an extremely high probability and can improve the service.

The variable winning ball device used in the above-mentioned embodiment shows a case where a pair of opening and closing blades are provided on the left and right of two upper and lower winning holes, respectively. The ball device is not limited to this and may have various other modified structures. For example, only one pair of opening / closing blades may be used, and a part in which the balls can be won when the opening / closing blades are opened may be the special prize area. Further, as another modified example, a variable prize ball device for opening and closing the opening and closing plate on the front of the game board is used, and a part where the balls can be won when the opening and closing plate is opened is a prize area. Good. Further, in the above-described embodiment, the specific condition and the repeated continuation condition are the same as the winning of the winning hole 21a, but the specific condition and the repeated continuation condition may be different. Further, the specific condition or the repetitive continuation condition may be any condition as long as the condition includes at least winning of a ball hitting the specific winning area.

Further, in the above-mentioned embodiment, as a game control state in which a relatively large game value can be given, a case has been described in which the opening / closing wing pieces are driven to open / close a maximum of n times, but even in a continuous opening operation. Good. For example, as an advantageous condition based on a specific condition at a time, it is possible to continuously open for a maximum of n · P1 / 2 hours, and the following prizes are awarded in the special prize area within the maximum time: The specific advantageous condition may be detected and the operation in the next advantageous state may be performed. Further, the special prize area is not limited to a part of the area provided in the winning ball device, but is a passing area or a winning area formed on the game board, and it is assumed that nail adjustment is performed so that it is relatively difficult to win a prize. Good.

Further, in the above-mentioned embodiment, the case where the game control circuit is constituted by a hard circuit is shown, but a program for performing the same operation as this may be assembled and processed by software by a microprocessor or the like. .

[0038]

As described above, according to the present invention,
The first and second movable member drive sources are provided in accordance with the pair of left and right movable members, and the first and second movable member drive sources are operated simultaneously. A driving force for changing the movable member in the opening direction and the closing direction can be simultaneously supplied to each movable member.
Moreover, since the movable member driving drive source is integrally provided with the variable winning ball device having the movable member, the movable member driving drive source and the corresponding movable member are assembled at the time of assembling the ball game machine. It becomes easy to attach the drive source for driving the movable member to the ball game machine with a relative positional relationship with the desired state. As a result, when the ball game machine is in operation, the driving force is not normally supplied to both movable members due to the improper positional relationship between the movable member driving source and the movable member, and the opening and closing directions are closed. It is possible to prevent the occurrence of problems such as hindering the change in direction as much as possible.
