It has been.

  As shown in FIG. 2, the variable winning ball apparatus 20 is provided with a box-shaped case 20 a whose entire surface is open, and a winning opening 21 is provided at the upper center. The entrances 22a and 22b are provided near the upper ends of both sides of the case 20a, and the ball receiving members 23a and 23b open and close the entrances 22a and 22b at one end at the lower ends of the entrances 22a and 22b. It is attached so that it can rotate. The upper ends of the ball receiving members 23a and 23b are rotatably attached to the other ends of the open / close bars 24a and 24b that are rotatably attached to the rear of the entrances 22a and 22b. The open / close bars 24a and 24b are rotated within a certain angle range by driving an electromagnetic solenoid 24c (not shown in FIG. 2), and the ball receiving members 23a and 23b are rotated to open and close the entrance ports 22a and 22b. It is supposed to be. The variable winning ball apparatus 20 is provided with a big winning sorting unit 25 for sorting the winning balls into a big winning that gives a special profit and a normal winning.

  The big winning selection unit 25 is provided with an opening 25a that continues from the top to the entrances 22a and 22b via a communication passage (not shown), and a winning ball detection switch 25b is attached to the rear side of the opening 25a. ing. A first turntable 25c is provided below the opening 25a so as to be rotatable clockwise around the vertical axis. The first turntable 25c is provided with an opening 25c1 for dropping the game ball downward at one place. A second rotating disk 25d having a diameter larger than that of the first rotating disk 25c is provided below the first rotating disk 25c. The second turntable 25d is rotatably arranged counterclockwise about a vertical axis provided coaxially with the first turntable 25c, and is provided with an opening 25d1 for dropping the game ball downward at one place. ing. A special winning opening 25e called a V zone that defines a big hit is provided at the center below the second rotary board 25d, and a winning opening 25f that defines a normal winning is provided on the left and right. A special winning ball detection switch 25g is provided inside the special winning opening 25e.

  Then, the game balls that have entered the entrances 22a and 22b fall through the communication passages to the first turntable 25c from the opening 25a. The game ball that has dropped onto the first rotary board 25c falls from the position of the opening 25c1 onto the second rotary board 25d. The game ball that has fallen on the second rotating board 25d falls downward from the opening 25d1. Then, when the opening 25c1 and the opening 25d1 overlap with the special winning opening 25e located in the central portion below the second turntable 25c, when the game ball falls from the opening 25c1, the gaming ball is awarded a special prize. A ball is entered into the mouth 25e so that a big prize can be obtained.

  When a big winning is achieved, for example, the ball receiving members 23a and 23b are continuously opened and closed 15 times or continuously opened and closed until ten game balls are won. Further, if the game ball enters the special winning opening 25e while the ball receiving members 23a and 23b are performing the continuous opening / closing operation, the right to continue is generated and the continuous opening / closing operation is immediately stopped, and a new one after a certain period of time. The continuous opening / closing operation of the ball receiving members 23a and 23b is started. During the continuous opening operation of the ball receiving members 23a and 23b, the winning balls are very easy to enter the special winning opening 25e, and thus the continuous opening and closing operation of the ball receiving members 23a and 23b is once started. Normally, the continuous opening / closing operation is continued after that. The continuous number of times of the continuous opening / closing operation is set to a fixed number of times, for example, 15 times, and the continuous number display unit 26 provided at the upper part of the opening 25a displays the number of continuous times. Further, a winning number display section 27 for displaying the number of winnings generated during the big winning is provided below the special winning opening 25e. In addition, about the aspect and the continuous frequency of the said continuous opening / closing operation | movement, it is an example and can be changed into various aspects and continuous frequency.

  Inside the start openings 14a and 14b, start winning ball detection switches 14c and 14d for detecting winning of game balls are provided. The variable symbol display unit 15 displays a variable symbol that defines the number of times the ball receiving members 23a and 23b are opened and closed based on the control of the control circuit 41, which will be described later. The selected symbol is displayed after the variable display of the symbol for a certain short time in accordance with the winning. For example, six even numbers and three odd numbers are used as the fluctuating symbols. When these are randomly generated and the even number is displayed, the number of times of opening and closing the ball receiving members 23a, 23b is set to the normal number of times. When the odd number is displayed, the number of times of opening and closing the ball receiving members 23a and 23b is set to 2 which is a special number. The special number is the number of times of opening and closing that is greater than the normal number.

  However, the variation pattern is not limited to this. For example, a plurality of numbers are prepared, a specific number is selected in advance, and the ball receiving members 23a and 23b are opened and closed when the specific number is displayed. When the number of times is set to 2 and other numbers are displayed, a method in which the number of times of opening and closing the ball receiving members 23a and 23b is set to 1 can also be used. Further, as a display method of the variation symbol display unit 15, the variation of the symbol is displayed at the start of the game, and when the game ball is won at the starting opening, the certain symbol is displayed for a certain period of time, and then the variation symbol is displayed again. There is also a method.

  A receiving tray 18 for storing game balls and receiving prize balls is provided below the game board 11 of the main body 10, and a lower tray 18 a is provided below the receiving tray. At the right end of the lower plate 18a, an operation handle 19 that is linked to a game ball launcher (not shown) is provided.

  Next, an electric control device for controlling the operations of the variable symbol display unit 15 and the variable winning ball device 20 will be described with reference to the block circuit diagram of FIG. The electric control device 40 is provided with a control circuit 41, and the control circuit 41 is constituted by a microcomputer including a ROM, a RAM, a CPU, a timer, a counter, an I / O, and the like. The “variable winning control program I” and the “variable winning control program II” corresponding to the flowchart shown in FIG. 5 are continued to be executed, and the “winning ball control interrupt program” corresponding to the flowchart shown in FIG. . Further, the control circuit 41 determines the number of opening and closing of the ball receiving member and the display pattern according to the value of the counter. For example, the control circuit 41 counts a number from 0 to 14, and 2/3 of them are counted. Corresponding to 1 open / close frequency, 1/3 corresponds to 2 open / close frequency. Then, the control circuit 41 associates six even numbers as display symbols with one open / close count, and associates three odd numbers as display symbols with two open / close counts.

  On the input side of the control circuit 41, the left and right start opening winning ball detection switches 14c and 14d, the winning ball detection switch 25b and the special winning ball detection switch 25g are connected. On the output side of the control circuit 41, the variable symbol display unit 15, the electromagnetic solenoid 24 c for the ball receiving member, the continuous number display unit 26, and the winning number display unit 27 are connected via the drive circuits 42 to 45. . The drive circuits 42 to 45 actuate the variable symbol display unit 15, the electromagnetic solenoid 24 c for the ball receiving member, the continuation number display unit 26, and the winning number display unit 27 in accordance with the output from the control circuit 41.

  Next, the operation of the first embodiment configured as described above will be described. By turning on the power switch (not shown) of the pachinko gaming machine, the execution of the “variable winning control program I” is started at step 50 shown in FIG. 4, and various variables are initialized at step 51. . Then, when the player supplies the game ball to the tray 18 and operates the operation handle 19, the game ball is continuously fired by a launching device (not shown), passes through the guide rail 11b, and passes through the game area 11a. Supplied in. When the game ball wins one of the start holes 14a and 14b, detection signals are output by the start opening winning ball detection switches 14c and 14d. In response to this, the control circuit 41 shifts the program to step 53 based on the determination of “YES” in step 52 and restricts the entrance of the game balls of the start ports 14a and 14b (hereinafter referred to as start port restriction). State). In other words, when a game ball enters the start opening 14a, 14b, this is regarded as a winning for the start opening, which is processed so as not to open and close the ball receiving members 23a, 23b.

  Next, in step 54, the control circuit 41 determines the number of times of opening and closing the ball receiving members 23a and 23b to be once or twice based on the counter number. Then, in step 55, whether the number of opening and closing is once or twice is selected, and in the case of one time, in step 56, a symbol variation signal representing a random number string is output for a predetermined time. In response to this, the drive circuit 42 causes the variation symbol display unit 15 to display the variation of the symbol for a certain period of time. Further, in a step 57 after a certain period of time, an even number symbol representing opening and closing of the ball receiving members 23a and 23b is displayed on the variation symbol display unit 15. In step 58, a signal for opening and closing the ball receiving members 23a and 23b once is output. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c and rotates the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened for a certain time, for example, 0.5 seconds. As a result, the game balls supplied to the game board 11 are given the possibility of entering the variable winning ball apparatus 20.

  When the number of times of opening and closing is 2, the selection is made twice at step 55, and a symbol variation signal representing a random number string is output for a predetermined time at step 60, and the drive circuit 42 displays a variation symbol display accordingly. The part 15 is made to display the fluctuation of the symbol for a certain period of time. Further, in a step 61 after a certain period of time, an odd symbol representing the two times opening and closing of the ball receiving members 23a and 23b is displayed on the variable symbol display unit 15. Then, in step 62, a signal for opening and closing the ball receiving members 23a and 23b is output twice. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c and rotates the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened twice at regular intervals for a certain period of time. Thereby, the possibility of entering a game ball into the variable winning ball apparatus 20 is increased. Then, after the opening and closing of the ball receiving members 23a and 23b is completed, the start port restricted state is released in step 59, the program is returned to step 52, and the above-described processing is repeated thereafter.

  As described above, according to the present embodiment, the number of times the game entrance is opened by opening and closing the ball receiving members 23a and 23b enabling the winning to the variable winning ball apparatus 20 is determined so that the game ball is the starting port 14a. , 14b, it is not immediately revealed to the player, but only after the display content of the variable symbol display unit 15 is confirmed. Therefore, the player can have a sense of expectation as to how many times the ball receiving members 23a and 23b are rotated, and the interest in the game is enhanced by making the progress of the game complicated.

  Furthermore, by dividing the number of opening / closing operations into a normal number of one time and a special number of two times, it is possible to enhance a sense of expectation for the occurrence of the special number of times. Also, expectation until the number of times of opening and closing is determined by providing a certain time from the winning of the game ball to the start openings 14a and 14b to the display of the opening and closing times of the ball receiving members 23a and 23b on the symbol display unit 15. A feeling is heightened.

  Then, during execution of the “variable winning control program I”, the control circuit 41 performs interruption execution of the “winning ball control interrupt program” shown in FIG. 5, and variable winning balls associated with opening and closing of the ball receiving members 23a and 23b. Operation control in the device 20 is performed. That is, the execution of the program is started at step 70 shown in FIG. 5, and the ball receiving members 23a and 23b are opened and closed once or opened twice at step 71 and step 81, that is, the electromagnetic solenoid 24c of the opening and closing bars 24a and 24b. It is determined whether the first driving or the second driving is started. That is, after a game ball is won in the start opening 14a or 14b and the variable symbol display unit 15 selects and displays one symbol, the electromagnetic solenoid 24c starts to be driven when a certain time has elapsed, and the ball receiving members 23a and 23b It rotates to open and close the entrances 22a and 22b. In the case of one-time driving, based on the determination of “YES” in step 71, the timer provided in the control circuit 41 starts counting for a predetermined time t 0 simultaneously with driving of the electromagnetic solenoid 24 c in step 72. . The predetermined time t0 is a time obtained by combining the opening / closing time tA1 until the single opening / closing of the ball receiving members 23a and 23b is completed and the big winning determination valid time tB. The big winning determination valid time tB is determined in consideration of the time until the winning ball that is won immediately before the ball receiving members 23a and 23b are closed enters the special winning opening, and is, for example, 4 seconds.

  Then, in step 73 and step 74, it is determined whether or not a ball has been entered into the ball entrances 22a and 22b within the opening / closing time tA1, that is, whether or not a winning ball has been detected. When the ball does not enter, the program is moved to step 75 based on the determination of “YES” in step 73, and the control circuit 41 ends the execution of the program. When the player has entered the ball, the program is moved to step 76 based on the determination of “YES” in step 74, and whether or not the player has entered the special winning opening 25e in step 76 and step 77 within a predetermined time t0. It is determined whether or not a large winning ball has been detected. When the big prize is not won, based on the determination of “YES” in step 76, the program is moved to step 75, and the control circuit 41 ends the execution of the program. When the big win is made, the program is moved to step 78 based on the determination of “YES” in step 77, and the winning of the game ball to the start openings 14a, 14b is the target of opening and closing the ball receiving members 23a, 23b. The start opening restriction state is set, and in step 79, a “big prize routine” is executed.

  In the “big prize routine”, as described above, the ball receiving members 23a and 23b are continuously opened and closed 15 times, or are continuously opened and closed until 10 game balls are won. If the game ball enters the special winning opening 25e during the operation, the continuation right is generated and the continuous opening / closing operation is immediately stopped, and a new continuous opening / closing operation is started after a certain time. When the execution of the “large winning routine” is completed, the starting port restricted state in which the winning of the game ball to the starting ports 14a and 14b is subject to opening / closing of the ball receiving members 23a and 23b is released in step 80. Thereafter, in step 75, the execution of the program ends.

  When the ball receiving member is opened and closed twice, based on the determination of “YES” in step 81, the timer provided in the control circuit 41 is set at a certain time simultaneously with the driving of the electromagnetic solenoid 24c in step 82. Start counting t1. The predetermined time t1 is a time obtained by combining the opening / closing time tA2 and the big winning determination valid time tB until the opening and closing of the ball receiving members 23a and 23b is completed twice.

  Then, at step 83 and step 84, it is determined whether or not a ball has been entered into the ball entrances 22a and 22b within the opening and closing time tA2, that is, whether or not a winning ball has been detected. When the ball does not enter, based on the determination of “YES” in step 83, the program is moved to step 75, and the control circuit 41 ends the execution of the program. When the ball is entered, the program is moved to step 85 based on the determination of “YES” in step 84, and whether or not the special winning opening 25e is entered within a predetermined time t1 in steps 85 and 86. It is determined whether or not a large winning ball has been detected. When the big prize is not won, based on the determination of “YES” in step 85, the program is moved to step 75, and the control circuit 41 ends the execution of the program. When a big prize is won, the program is moved to step 87 based on the determination of "YES" in step 86, and the ball receiving members 23a and 23b are opened / closed to enter the starting balls 14a and 14b. A start opening restriction state that is not a target is set, and in step 88, a big winning routine is executed. When the execution of the “large winning routine” is completed, the starting port restricted state in which the ball is inserted into the starting ports 14a and 14b for opening and closing the ball receiving members 23a and 23b is released in step 89. After that, in step 75, execution of the program ends. As described above, the operation control in the variable winning ball apparatus 20 is performed when the ball receiving members 23a and 23b are opened and closed once and twice.

  Next, a second embodiment will be described with reference to the drawings. In the second embodiment, as shown in FIG. 6, the variable symbol display section 46 is divided into two display areas 46a and 46b, and the left display area 46a is made to correspond to the left start port 14a shown in FIG. The right display area 46b corresponds to the right start port 14b. Drive circuits 47a and 47b are provided in the display areas 46a and 46b, respectively. As a result, the circuit configuration of the electric control device according to the second embodiment is as shown in FIG. Further, the control circuit 41 determines the number of opening and closing of the ball receiving member and the display pattern according to the value of the counter as in the first embodiment. Then, for example, the control circuit 41 associates 10 different sets of display symbols with respect to the number of times of opening and closing, and 5 sets of the same set of display symbols with respect to the number of times of opening and closing of 2 times. The flowchart of “variable winning control program II” is configured as shown in FIG. Other configurations are the same as those in the first embodiment.

  The operation of the second embodiment configured as described above will be described. As described in the first embodiment, by turning on a power switch (not shown) of the pachinko gaming machine, the execution of the “variable winning control program II” is started at step 100 shown in FIG. Various variables are initialized at 101, and at the same time, the display of both display areas 46a and 46b is set to "1". Next, in step 102, the display contents of the left and right display areas 46a and 46b are read. Here, “1” is stored in the control circuit 41 for both left and right. Then, in step 103 and step 104, it is determined whether the game ball has won a prize in either the left starting port 14a or the right starting port 14b. When the game ball wins the left starting port 14a, the program is moved to step 105 based on the determination of “YES” in step 103, and the starting port is limited.

  Next, in step 106, the control circuit 41 determines whether the number of times of opening and closing the ball receiving members 23a and 23b is one or two based on the counter value. Then, in step 107, whether the number of opening and closing times is one or two is selected, and in the case of one time, a symbol variation signal representing a numeric string is output for a predetermined time in step. In response to this, the drive circuit 47a displays the variation of the symbol for a certain period of time in the left display area 46a. Further, in a step 109 after a certain period of time, a symbol different from the right display region 46b is displayed in the left display region 46a, indicating that the ball receiving members 23a and 23b are opened and closed once. In step 110, a signal for opening and closing the ball receiving members 23a and 23b once is output. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c, and rotates the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened for a certain time, for example, 0.5 seconds. As a result, the game balls supplied to the game board 11 are given the possibility of entering the variable winning ball apparatus 20.

  When it is determined that the number of times of opening and closing is two times, the number of times of opening and closing is selected in step 107, and in step 112, a symbol variation signal representing a random number string is output for a predetermined time. In response to this, the drive circuit 42 causes the left display area 46a to display the variation of the symbol for a certain period of time. Further, in step 113 after a predetermined time, the same design as that of the right display region 46b is displayed in the left display region 46a, indicating that the ball receiving members 23a and 23b are opened and closed twice. In step 114, a signal for opening and closing the ball receiving members 23a and 23b is output twice. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c and rotates the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened twice. Thereby, the possibility of entering the game ball supplied to the game board 11 into the variable winning ball apparatus 20 is increased. Then, after the opening and closing of the ball receiving members 23a and 23b is completed, the start port restricted state is released in step 111, the program is returned to step 52, and the above-described processing is repeated thereafter.

  When the game ball wins the right start opening 14b, the program is moved to step 115 based on the determination of “YES” in step 104, and the start opening is limited. In step 116, the number of times the ball receiving members 23a and 23b are opened and closed is determined. If it is once, the number of times of opening and closing is selected at step 117, and the fluctuation of the symbol for a certain time is displayed in the right display area 46b at step 118. Then, after the variable display is stopped, a symbol different from the left display area 46a is displayed in the right display area 46b in step 119. In step 120, a signal for opening and closing the ball receiving members 23a and 23b once is output. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c and rotates the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened once.

  When it is determined that the number of times of opening and closing is two, the number of times of opening and closing is selected at step 117, and at step 121, a symbol variation signal representing a random number string is output for a certain period of time. In response to this, the drive circuit 47b displays the variation of the symbol in the right display area 46b for a certain period of time. Further, in a step 122 after a predetermined time, the same symbol as that of the left display region 46a is displayed in the right display region 46b, indicating that the ball receiving members 23a and 23b are opened and closed twice. In step 123, a signal for opening and closing the ball receiving members 23a and 23b is output twice. In response to this, the drive circuit 43 excites the electromagnetic solenoid 24c and rotates the ball receiving members 23a and 23b to enter the ball receiving members 23a and 23b. The ball openings 22a and 22b are opened twice.

  Then, after the opening and closing of the ball receiving members 23a and 23b is completed, the start port restricted state is released in step 111, the program is returned to step 102, and the above-described processing is repeated thereafter. Note that the “winning ball control interrupt program” is interrupted and executed during the repeated execution of the “variable winning control program II”, as in the first embodiment.

  As described above, in the second embodiment, it is immediately clear to the player how many times the ball receiving members 23a and 23b are opened and closed by winning the game balls in the start openings 14a and 14b. The display contents of the display areas 46a and 46b corresponding to the winning start opening of the variable symbol display unit 46 are fixed, and the display contents of the display areas corresponding to other starting openings are determined to be different from each other. For the first time. Therefore, the player can have a sense of expectation as to how many times the ball receiving members 23a and 23b are opened and closed, and the progress of the game is complicated, thereby enhancing the interest of the game.

  Furthermore, by dividing the number of opening and closing operations into a normal number of times and a special number of two times, it is possible to increase the expectation for the occurrence of the special number of times, and due to the difference in the design of the display areas 46a and 46b. Easier to distinguish between normal and special times. In addition, the provision of a certain period of time from the winning of a game ball to the start ports 14a and 14b until the display of the number of times of opening and closing the ball receiving members 23a and 23b increases the sense of expectation until the number of times of opening and closing is determined.

  In the above embodiment, the variable winning ball apparatus has been described with respect to the type using the first and second rotating discs. However, the variable winning ball apparatus has other various types. The present invention can be applied to any type.
