The start winning signal is output as a high signal when the passage of the game ball is not detected, but is output as a low signal only while the game ball passes. An optical or mechanical sensor may be used as the start winning sensor.

  On the back surface of the mounting plate 42, two left and right bearing portions 43, 44 projecting rearward are provided. The bearing portions 43 and 44 are respectively provided with bearing grooves 43a and 44a that are open upward and extend to the left and right. In addition, bearing holes 107a and 107b are formed in the left and right side walls of the partition wall 107 so as to penetrate the respective wall surfaces to the left and right.

  The rectangular flat plate-shaped left opening / closing door 61 constituting the left prize winning device 60 has engagement shafts 63 and 64 provided at both left and right ends and projecting left and right respectively. The engagement shaft 63 is fitted into the bearing groove 43a, and the engagement shaft 64 is mounted in the bearing hole 107a. Thus, the left opening / closing door 61 attached to the winning device 40 can be rotated in the front-rear direction of the game board 20 with a rotation shaft 65 extending left and right at one end side as a rotation center. That is, the left open / close door 61 has a closed position in which the left big prize opening 62 is closed in an upright state, and an open position in which the upper end is inclined forward with respect to the game board 20. In the meantime, the rotary shaft 65 can be rotationally displaced about the rotational center. In addition to the engagement shaft 63, a locking piece 66 that extends to the left and engages with a long hole 85 of a restriction piece 84 that will be described later is provided at the left end of the left opening / closing door 61.

  Similarly, a rectangular flat plate-shaped right opening / closing door 71 constituting the right prize winning device 70 is provided with engagement shafts 73 and 74 provided on the left and right sides and projecting left and right respectively. The engagement shaft 73 is fitted into the bearing groove 44a, and the engagement shaft 74 is mounted in the bearing hole 107b. Thus, the right opening / closing door 71 attached to the winning device 40 can be rotated in the front-rear direction of the game board 20 with a rotation shaft 75 extending left and right at one end side as a rotation center. That is, the right open / close door 71 rotates the rotary shaft 75 between a closed position where the right big prize opening 72 is closed in an upright state and an open position inclined forward with respect to the game board 20. The center can be turned and displaced. In addition to the engagement shaft 73, a locking piece 76 that extends to the right and engages with a long hole 95 of a regulating piece 94 described later is provided at the right end of the right opening / closing door 71.

  Left and right big prize opening solenoids having plungers 82 and 92 that are vertically movable and vertically movable as drive mechanisms for respectively opening and closing the left and right open / close doors 61 and 71 configured as described above. 81 and 91 are arranged in the winning device 40. Here, the opening / closing door drive mechanism will be described using the right large prize-opening solenoid 91 or the like disposed to open / close the right opening / closing door 71 as an example. As shown in FIG. 9, the drive mechanism includes a solenoid 92, a plunger 92, a spring 93, and a restriction piece 94.

  In a state where the solenoid 91 is not energized, the plunger 92 is kept in a state of protruding downward by a restoring force in a direction along the plunger 92 of the spring 93 placed on the plunger 92. A restriction piece 94 having a crank shape in a side view is attached to the tip of the plunger 92. A long hole 95 extending in the front-rear direction is provided on the side surface of the front end portion of the restriction piece 94, and the long hole 95 is engaged with the locking piece 76 of the right opening / closing door 71. The restoring force of the spring 93 is transmitted to the locking piece 76 that engages with the elongated hole 95 via the regulating piece 94, and the locking piece 76 is pressed downward to bring the right opening / closing door 71 into an upright closed position. (Right open / close door 71 represented by a solid line in FIG. 9).

  When the plunger 92 is pulled into the solenoid 91 against the restoring force of the spring 93 by energizing the solenoid 91, the regulating piece 94 is moved upward together with this. At this time, the locking piece 76 moves in the elongated hole 95 to the proximal end side of the regulating piece 94. Then, the right opening / closing door 71 is rotated in the direction of arrow D in FIG. 9 with the rotation shaft 75 at the lower end thereof as a rotation center by its own weight, and is tilted forward with respect to the game board 20. 70 is opened (the right door 71 in the open position in FIG. 9 is indicated by a chain line). Further, the right opening / closing door 71 tilted forward to a predetermined angle by its own weight is restricted from further rotation by the engagement of the locking piece 76 and the restricting piece 94, and the right opening / closing door 71 is more than the predetermined amount. It is prevented from tilting forward to this angle.

  On the other hand, when the energization to the solenoid 91 is cut off, the plunger 92 protrudes downward by the restoring force of the spring 93, and the restriction piece 94 moves downward accordingly. Therefore, the locking piece 76 moves to the front end side of the long hole 95 and is pressed downward, and the right opening / closing door 71 rotates rearward (to the game board 20 side) around the rotation shaft 75 to the right. The big prize device 70 is closed. The drive mechanism for opening and closing the right open / close door 71 has been described above as an example. However, the drive mechanism for opening and closing the left open / close door 61 is the same as in the case of the right open / close door 71. The left opening / closing door 61 has a plunger 82, a spring 83, and a restriction piece 84. The restriction piece 84 attached to the tip of the plunger 82 is engaged with the locking piece 66 of the left opening / closing door 61. The opening / closing operation is controlled.

  A right rolling surface 101 that is inclined slightly downward toward the back side of the winning device 40 is formed inside the winning device 40 and on the right large winning opening 72 side, and similarly, on the left large winning opening 62 side. Is formed with a left rolling surface 102 that is inclined slightly downward toward the back side of the winning device 40 (see FIG. 6). Furthermore, a part of the left rolling surface 102 is divided into left and right regions by a partition wall 105 extending forward and backward on the left rolling surface 102, and is left on the right side in the plan view with the first ball passage side rolling surface 103 on the right side. The second ball passage side rolling surface 104 is formed. In addition, a rolling surface 106 that connects the first ball passage side rolling surface 103 and the right rolling surface 101 is formed to be inclined downward from the first ball passage side rolling surface 103 side toward the right rolling surface 101 side.

  A first ball passage 111 called a non-specific region is located on the right back corner side of the right rolling surface 101, and a first region called a specific region (so-called V zone) is located on the back side of the first ball passage side rolling surface 104. Two-ball passages 112 are formed so as to extend downward. In addition, a shutter 121 that moves and displaces in the left-right direction to open and close the entrance of the second ball path 112 is disposed on the upper part of the second ball path 112 so as to extend left and right.

  As a driving mechanism for the shutter 121, a specific area solenoid 122 having a plunger 123 that can move to the left and right is provided on the left side of the shutter 121. The shutter 121 is formed in an L shape when viewed from the front, and its proximal end is attached to the distal end portion of the plunger 123. In the state where the specific area solenoid 122 is not energized, as shown in FIGS. 6 and 7, the plunger 123 protrudes to the right due to the restoring force in the direction along the plunger 123 of the spring 124 placed on the plunger 123. It keeps the state. In this state, the entrance of the second spherical passage 112 is closed by the shutter 121. For this reason, the game ball that has flowed on the first ball passage side rolling surface 104 cannot enter the second ball passage 112 and flows rightward on the rolling surface 106 toward the first ball passage 111.

  When the specific area solenoid 122 is energized and the plunger 123 is pulled into the specific area solenoid 122 against the restoring force of the spring 124, the shutter 121 moves to the left along with this. For this reason, the entrance of the second ball passage 112 is opened, and the game ball flowing through the first ball passage-side rolling surface 104 can enter the second ball passage 112. On the other hand, when the energization to the specific area solenoid 122 is cut off, the plunger 123 moves to the right by the restoring force of the spring 124, and accordingly, the shutter 121 moves to the right to close the entrance of the second ball passage 112. .

  The first ball passage 111 has a detection hole 131a having a substantially octagonal shape in plan view through which a game ball can pass, and a ball detection sensor that magnetically detects the detection when the game ball passes through the detection hole 131a. 131 is provided (see FIGS. 6 and 7). The sphere detection sensor 131 is accommodated in a front-rear direction by a sensor holder 132 provided in the first sphere passage 111. The sphere detection sensor 131 outputs a sphere detection signal that takes two states, a high signal and a low signal. The ball detection signal is output as a high signal when the passage of the game ball is not detected, but is output as a low signal only while the game ball passes. An optical or mechanical sensor may be used as the sphere detection sensor 131.

  Similarly, the second ball passage 112 has a detection hole 133a having a substantially octagonal shape in plan view through which a game ball can pass, and this is detected magnetically when the game ball passes through the detection hole 133a. A sphere detection sensor 133 is provided (see FIGS. 6 and 7). The sphere detection sensor 133 is accommodated in the front-rear direction by a sensor holder 134 provided in the second sphere passage 112. The sphere detection sensor 133 outputs a sphere detection signal that takes two states, a high signal and a low signal. The ball detection signal is output as a high signal when the passage of the game ball is not detected, but is output as a low signal only while the game ball passes. An optical or mechanical sensor may be used as this sphere detection sensor.

  The lower portion of the first ball passage 111 is communicated with a winning ball discharge passage 115 that is formed in the lower passage 114 and extends downward, and the game balls that have passed through the first ball passage 111 pass through the lower passage 114. The winning ball discharge passage 115 is discharged to the back surface of the game board 20. Similarly, the lower part of the second ball passage 112 is open to the lower passage 114 and communicates with a winning ball discharge passage 115 that extends downward. A game ball that has passed through the second ball passage 112 passes through the lower passage 114. The winning ball is discharged from the winning ball discharge passage 115 to the back surface of the game board 20.

  Next, an outline of a control system for controlling the pachinko machine PM will be described. As shown in FIG. 10, the present control system is based on the ball detection sensors 131 and 133, the start winning sensor 135, the solenoid relay board 800, and the solenoids 81, 91, and 122 that are game board side electrical components disposed on the game board 20. The symbol display device 28 and the like and the above-mentioned main board 700 which is a frame-side electric component disposed on the back set board 30 are electrically connected by a cable or the like.

  The main board 700 includes a system program that manages the entire operation of the pachinko machine PM, a storage unit that is pre-stored with a game execution program, and a microprocessor that executes these programs (hereinafter, “ And a random number generator 720 for generating random numbers for symbol lottery (for example, 65536 random numbers from 0 to 65535) regardless of the control of the main board 700. Further, the control unit 710 has a winning device control means B77 for controlling the opening / closing operation of the open / close doors 61, 71, etc. by outputting a solenoid drive signal to each solenoid 81, 91, 122.

  Further, the main board 700 is connected to the ball detection sensors 131 and 133 to receive the ball detection signals from the ball detection sensors 131 and 133, and is connected to the start winning sensor 135 to detect the detection signal (starting from the starting winning sensor 135). Signal) is input. On the other hand, the left big prize winning opening solenoid 81, the right big prize winning opening solenoid 91 and the specific area solenoid 122 are respectively connected to the main board 700 via the solenoid relay board 800, and the solenoid drive signal from the main board 700 is connected to the solenoid. Each solenoid 81, 91, 122 is input via the relay substrate 800 to drive each solenoid 81, 91, 122. Further, when a symbol display signal from the main board 700 is input to the symbol display device 28, the symbol display device 28 is activated to display a variable display of symbols in a plurality of symbol display units.

  The CPU 711 of the control unit 710 has a symbol lottery means B73 and a hit determination means B75. When the main board 700 detects a low signal (start signal) from the start winning sensor 135, the symbol lottery means B73 acquires one count value of 65536 random numbers generated sequentially from the random number generator 720. Thus, the stop symbol in the symbol display device 28 is determined.

  In addition to the CPU 711 described above, the control unit 710 is provided with a ROM 712, and a control program to be executed by the CPU 711 and data necessary for the control process are described in the ROM 712. Of these necessary data, for example, symbol data for determining a stop symbol in the symbol display device 28 is recorded in the symbol data table B74. Each symbol data is given an address number, and one symbol data is specified from one address number. As described above, when a low signal (start signal) from the start winning sensor 135 is detected, the count value for the symbol lottery selected from the random numbers generated by the random number generator 720 and the symbol data in the symbol data table B74 are displayed. The stop symbol is selected by collation. Then, a predetermined symbol selected based on the symbol display signal from the main board 700 is displayed on the symbol display device 28.

  As described above, a “special symbol” (for example, “147”, “258”) composed of a three-digit pattern or combination of numbers selected based on the lottery result by the symbol lottery means B73 is displayed on the symbol display device 28. Although this special symbol is displayed on the liquid crystal screen, a symbol consisting of a combination of the same type of all three digits (for example, “111”, “777”) is referred to as a “big hit symbol”.

  In addition, in the hit determination table B38 on the ROM 733, a unique determination result of “winning random number” or “losing random number” with respect to one random number value is determined for the entire range of acquired random number values. Data is recorded. That is, the 65536 random number values always belong to either the winning random number or the lost random number, and do not belong to both or neither. Here, the winning random number refers to a random value that causes the symbol display device 28 to stop display a predetermined symbol combination that generates a jackpot game. The hit determination means B37 compares the count value lottery by the symbol lottery means B35 with the determination table B38 and determines whether or not the determination result corresponding to the count value, that is, the count value is a hit random number, Judge whether it is a lost random number.

  When the count value lottery by the symbol lottery means B35 is determined to be a random number by the hit determination means B37, the winning device control means B76 of the controller 710 sends a solenoid drive signal to each solenoid 81, 91, 122. And the left opening / closing door 61 and the right opening / closing door 71 are simultaneously displaced to their open positions, and the shutter 121 is opened. In addition, when the count value lottery by the symbol lottery means B35 is a random number, it is possible to output a solenoid drive signal only to the solenoid 81 of the solenoids 81, 91. That is, it is also possible to open only the left open / close door 61 during the big hit game. The same applies to the solenoid 91, that is, the right opening / closing door 71.

  It is also possible to cause the solenoid 81 and the solenoid 91 to alternately output solenoid drive signals every time a random number is drawn by the symbol lottery means B35. That is, the opening of the left opening / closing door 61 and the opening of the right opening / closing door 71 can be alternately repeated every time a big hit game is generated. Further, a solenoid drive signal is output continuously only to the solenoid 81, and only the left open / close door 61 is continuously opened a predetermined number of times, and then a solenoid drive signal is output continuously only to the solenoid 91, Only the open / close door 71 may be continuously opened a predetermined number of times.

  Next, an outline of the game in the pachinko machine PM according to the present invention will be described with reference to the flowcharts of FIGS. In the flowcharts shown in FIG. 11 and FIG. 12, the parts of the circle A are connected to form one flowchart, the parts of the circle B are connected to form one flowchart, and the circle C The parts are connected to each other to form one flowchart. First, when a player operates the operation handle 8, a hit ball is shot on the game board 20. The hit ball falls on the game board 20 while contacting a nail or the like (not shown) provided on the game board 20.

  In step S <b> 1, it is determined whether or not the game ball falling on the game board 20 has won the start winning tool 50. Here, when it is determined that the start winning tool 50 has been won, and the number of reserved balls has already reached four, a horizontal rectangle is formed in the upper ball tray 6 and the front frame 2 is opened and closed. A predetermined number (for example, five balls) of prize balls are paid out to the player from the prize ball payout opening 6b provided on the upper left side of the possible pad 6a (step S2), and the process proceeds to step S3. On the other hand, when it is determined that the number of reserved balls is less than four and that the winning prize 50 is won during the variable display on the symbol display device 28, the number of reserved balls is incremented by one. A predetermined number (for example, five balls) of prize balls are paid out to the player (step S2), and the process proceeds to step S3.

  If it is determined in step S1 that the starting prize 50 has not been won, it is determined whether or not the general prize 25 is won in step S20, and the general prize 25 is not won here. If it is determined that it has been, the process immediately proceeds to step S3. If it is determined in step S20 that the player has won the general prize device 25, a predetermined number (for example, five balls) of prize balls are paid out to the player from the prize ball payout opening 6b (step S20). S21), the process proceeds to step S3.

  If it is determined in step S3 that the number of reserved balls stored in the control unit 710 is 0, the subsequent symbol variation process is not executed, while the number of reserved balls is 1 or more and 4 If it is determined that the following is true, 1 is subtracted from the number of reserved balls. Then, a control signal is output from the main board 700 to the symbol display device 28, and the symbol display device 28 is activated to start symbol variation display (step S4). In the case where the striking ball wins the start winning tool 50 during the symbol variation display on the symbol display device 28, the controller 710 stores up to four reserved balls and stores the number of stored balls. Thereafter, the subsequent operation of the symbol display device 28 is guaranteed. The stored number of reserved balls can be recognized by the player when the special symbol holding lamps 29, 29, 29, 29 on the game board 20 are turned on.

  In subsequent step S5, the symbol lottery means B73 acquires one count value from the random numbers generated by the random number generator 720, and selects a stop symbol corresponding to the count value. Then, a predetermined symbol selected based on the symbol display signal from the main board 700 is displayed on the symbol display device 28 (step S6).

  At this time, whether or not the count value acquired by the symbol lottery means B73 is a predetermined winning value is determined by the hit determining means B75 (step S7), and unless it is the predetermined winning value, that is, the symbol display device 28. Unless the symbol stopped and displayed is a predetermined jackpot symbol, the solenoid drive signal is output from the main board 700 to the solenoids 81 and 91, so that the solenoids 81 and 91 are not energized and the left and right open / close doors 61 and 71 are not energized. Remains upright, and the left and right big prizes 60 and 70 remain closed (step S8). In such a closed state of the left and right open / close doors 61, 71, the game balls cannot enter into the big prizes 60, 70. For this reason, the game ball falling on the game board 20 does not enter the big prizes 60 and 70 and reaches the lower outlet 27.

  On the other hand, when the hit determination means B75 determines that the count value acquired by the symbol lottery means B73 is a predetermined winning value, that is, as a result of the symbol fluctuation in the symbol display device 28, the special value that is stopped and displayed. When the symbol is a predetermined jackpot symbol, a “hit game” is generated. In this jackpot game, the solenoid drive signal is output from the winning device control means B77 to the solenoids 81 and 91, the solenoids 81 and 91 are energized, and the left and right open / close doors 61 and 71 are normally closed. The left big prize tool 60 and the right big prize tool 70 are simultaneously opened to a position inclined forward by a predetermined angle (step S9). In such an open state, the left and right open / close doors 61, 71 receive the game balls falling on the game board 20, and the game balls can enter the left and right big prizes 60, 70. At this time, in the winning device 40, a control signal is output from the winning device control means B77 toward the specific area solenoid 122, the specific area solenoid 122 is energized, and the shutter 121 moves to the left to move the second ball passage 112. The entrance is opened (step S10).

  After the left and right open / close doors 61 and 71 are opened, the game balls that are received by the right open / close door 71 and enter the right rolling surface 101 enter the first ball passage 111. At this time, the game ball passes through the detection hole 131a of the ball detection sensor 131 provided in the first ball passage 111 and is detected (step S11), and a predetermined number (from the prize ball payout exit 6b) For example, 15 prize balls are paid out (step S12). Of the game balls that are received by the left opening / closing door 61 and enter the left rolling surface 102, the gaming balls that pass through the first ball passage side rolling surface 103 on the right side of the partition wall 105 are rolling surfaces 106 that tilt downward. Is guided to the right rolling surface 101 side and enters the first ball passage 111. At this time, the game ball passes through the detection hole 131a of the ball detection sensor 131 provided in the first ball passage 111 and is detected (step S11), and a predetermined number (from the prize ball payout exit 6b) For example, 15 prize balls are paid out (step S12).

  On the other hand, among the game balls received by the left opening / closing door 61 and entering the left rolling surface 102, the game balls passing through the second ball passage side rolling surface 104 on the left side of the partition wall 105 are in the second ball passage 112. Rush into. At this time, the game ball passes through the detection hole 133a of the ball detection sensor 133 provided in the second ball passage 112 and is detected (step S13), and a predetermined number (from the prize ball payout exit 6b ( For example, 15 prize balls are paid out (step S14). At the same time, when the game ball is detected by the ball detection sensor 133, a control signal is output from the winning device control means B77 toward the specific area solenoid 122, the power supply to the specific area solenoid 122 is cut off, and the shutter 121 is released. It moves to the right and the entrance of the second ball passage 112 is closed (step S15). Thereafter, until the opening and closing doors 61 and 71 are opened again, the shutter 121 remains closed at the entrance of the second ball passage 112.

  The left and right big prizes 60 and 70 are released all at once and a predetermined time (for example, 30 seconds) elapses, or a predetermined number (for example, 10 balls) of a winning is detected by the ball detection sensors 131 and 133. If any condition is satisfied (step S16), it is temporarily closed (step S17). When it is determined that there is a prize in the second ball passage 112 (specific area) provided inside the prize winning device 40 while the left and right big prizes 60 and 70 are open ( Step S18), the big prizes 60, 70 are once closed as described above and then opened again. As a result, the opening of the big prizes 60 and 70 can be continued a predetermined number of times (for example, 16 times). In addition, when the big prizes 60, 70 have been opened a predetermined number of times (for example, 16 times) (step S19), or when there is no prize in the second ball passage 112 while the big prizes 60, 70 are being opened. This jackpot game ends.

  Although preferred embodiments of the present invention have been described so far, the scope of the present invention is not necessarily limited to the above-described embodiments. For example, in the above embodiment, a game ball is won in the start winning tool 50, and the left big winning tool 60 and the right big winning tool 70 are simultaneously controlled by the winning device control means B77 according to the winning result by the symbol lottery means B73. However, every time the symbol lottery means B73 wins, the left big prize tool 60 and the right big prize tool 70 are released (the first special game that the left big prize tool 60 is opened and the right big prize). The second special game for releasing the tool 70 may be performed alternately. That is, as shown in FIG. 14 (“Start” represents a start prize tool and “Large” represents a big prize tool. The same applies in FIG. 15), when the start prize tool 50 is won, a left big prize is first given. The tool 60 is released (indicating that the big prize tool surrounded by the diagonal line is opened), and when the start prize tool 50 is won next time, the right big prize tool 70 is opened, and then the start prize tool. For example, the left big prize tool 60 may be opened when winning 50, and the opening of the left big prize tool 60 and the opening of the right big prize tool 70 may be repeated.

  Hereinafter, with respect to the outline of the game when the left and right big prizes are alternately released for each prize, referring to the flowchart of FIG. 13 focusing on the difference from the case where the left and right big prizes are released all at once. explain. 11 and FIG. 13 are connected to each other to form one flowchart, and the circles B in FIG. 11 and FIG. 13 are connected to each other to form one flowchart.

  When the winning prize is won during the continuation of the game and the count value acquired by the symbol lottery means B73 is determined to be a predetermined winning value by the hit determination means B75, that is, in the symbol display device 28. As a result of the symbol variation, when the special symbol to be stopped and displayed is a predetermined jackpot symbol, a “hit game” is generated as in the case where the left and right big prizes are released all at once.

  In this case, the winning device control means B77 determines which of the left and right big winning devices 60 and 70 is released in the previous jackpot game (step S30). At this time, in the previous jackpot game, for example, when it is determined that the right big prize tool 70 is released, the left big prize tool 60 is released. In other words, in this jackpot game, a solenoid drive signal is output from the winning device control means B77 to the left big winning tool opening solenoid 81, the solenoid 81 is energized, and the left opening / closing door 61 is predetermined with respect to the game board 20. The left big prize device 60 is opened (step S31).

  In such an open state, the left open / close door 61 receives the game ball falling on the game board 20 and can enter the game ball into the left big prize device 60. At this time, in the winning device 40, a control signal is output from the winning device control means B77 toward the specific area solenoid 122, the specific area solenoid 122 is energized, and the shutter 121 moves to the left to move the second ball passage 112. The entrance is opened (step S32).

  Thereafter, as in the embodiment in which the left and right big prizes are released all at once, the detection of the passage of the game ball to the first ball passage 111 (step S33), the prize when the passage of the game ball is detected. The ball is paid out (step S34). At this time, the passage of the game ball to the second ball passage 112 is detected (step S35), and the prize ball is paid out when the passage of the game ball is detected (step S36). And the entrance of the second ball passage 112 is closed (step S37).

  The left large winning tool 60 is determined by whether a predetermined time (for example, 30 seconds) elapses after being opened or whether a predetermined number (for example, 10 balls) of the winning is detected by the ball detection sensor 131 ( Step S38) is closed once when any of the conditions is satisfied (Step S39). And when it is judged that there was a prize to the 2nd ball passage 112 (specific field) provided inside prize-winning device 40, while left big prize tool 60 was opened (Step S40), The left big prize device 60 is once closed as described above and then opened again. Thereby, the opening of the left big prize device 60 can be continued a predetermined number of times (for example, 16 times). In addition, when the left big prize tool 60 has been opened a predetermined number of times (for example, 16 times) (step S41), or when the left big prize tool 60 is not opened while the second big prize tool 60 is opened, This jackpot game ends.

  After the jackpot game where the left big winning tool 60 is opened as described above, when the “big hit game” occurs again while the game is continuing, the winning equipment control means B77 makes the left big game in the previous big hit game. It is determined that the winning tool 60 has been opened, and a solenoid drive signal is output from the winning device control means B77 toward the right big winning tool releasing solenoid 91, and the right big winning tool 70 is opened (step S42).

  When the right big prize tool 70 is opened, the big hit game is executed in the same flow as the steps S32 to S38 when the left big prize tool 60 is opened. Then, the right big prize device 60 satisfies any of the conditions by determining whether a predetermined time (for example, 30 seconds) has elapsed since opening or a predetermined number (for example, 10 balls) has been detected. When it is satisfied, it is closed once (step S43). When it is determined that there is a winning in the second ball passage 112 (specific area) while the right big winning tool 70 is open (step S44), the right big winning tool 70 is as described above. Once closed, it is opened again. Thereby, the opening of the right big prize device 70 can be continued a predetermined number of times (for example, 16 times). Further, when the right big prize tool 70 has been opened a predetermined number of times (for example, 16 times) (step S45), or when the right big prize tool 70 is not opened while the right big prize tool 70 is opened, This jackpot game ends.

  In this way, the winning device control means B77 can be controlled so that the opening of the left big winning device 60 and the opening of the right big winning device 70 are alternately repeated every time a big hit game is generated. Yes.

  The opening of the big prizes 60 and 70 is not limited to the one in which the opening of the left big prize tool 60 and the opening of the right big prize tool 70 are alternately repeated every time a big hit game is generated. After the tool 60 is continuously opened a predetermined number of times, the right big prize tool 70 is opened a predetermined number of times, and the left big prize tool 60 is continuously opened a predetermined number of times. May be.

  Further, for example, when it is determined in step S40 shown in FIG. 13 that there is a winning in the second ball passage 112 (specific area) while the left big winning tool 60 is open, as shown in FIG. Instead of opening the left big prize tool 60 again (step S31), the right big prize tool 70 may be opened. That is, instead of opening the left big prize tool 60 and the right big prize tool 70 alternately for each jackpot game as described above, the left big prize tool 60 and the The right big prize device 70 may be configured to be opened alternately for a limited predetermined number of times. The same applies to the case where it is determined in step S44 that there is a winning in the second ball passage 112. Furthermore, not only the left big prize tool 60 and the right big prize tool 70 are opened alternately, but also the left big prize tool 60 and the right big prize tool 70 are configured to be combined to be opened. Also good. As described above, according to the present invention, a variety of games can be planned even within a single jackpot game.

  In the above-described embodiment, the left big prize opening 62 and the right big prize opening 72 are formed to have the same length in the left and right, so that the left big prize tool 60 and the right big prize tool 70 Are configured to have the same length on the left and right (see FIG. 15A), but by changing the left and right lengths of the left big winning opening 62 and the right big winning opening 72, FIG. As shown in b), the right big prize is configured to be longer to the left and right than the left big prize, or, as shown in FIG. 15C, the left big prize is changed to the right big prize. It can also be configured to be longer from side to side. If comprised in this way, depending on the fall path | route of the game ball which falls on a game board, it will become easy to drop a game ball by the side of a left big prize tool, or it will be easy to drop by the side of a right big prize tool. It becomes.

  As described above, in the ball game machine according to the present invention, the prize winning devices arranged in parallel on the left and right for each lottery win by the lottery means are configured to alternately open and close, or , Because it is possible to configure so that the big prizes arranged in parallel on the left and right for each lottery winning by the lottery means can be opened and closed synchronously, so this configuration is rich in variations The game can be executed and the game performance can be improved.
