In other words, the front edge of the flat door 220 is inclined as the inclined front edge 224 from the left front corner 221a to the middle portion 222a in the front-rear direction of the right end 222 in a straight line. Is formed.

  Accordingly, the flat opening / closing door 220 extends forward from the right end 222 of the closed opening / closing door 220 among the upper ends of the inclined front edge 224, the window glass FD2, and the right side wall 213. A right triangular auxiliary opening surface is formed so as to be perpendicular to the front opening surface. As shown in FIG. 3, the right-angled triangular auxiliary opening surface has a front-rear direction from the left front corner portion 221a of the left end portion 221 of the flat opening / closing door 220 to the right end portion 222, as shown in FIG. It means that it inclines linearly toward the intermediate part 222a.

  Of the left and right side guide plates 200b, 200c, the left guide plate 200b is a U-shaped big prize so as to incline in a gradual straight line from the right end to the lower left side as shown in FIG. 3 or FIG. It extends along the left end portion of the front decorative board 120a from the upper end portion of the left wall 212 of the mouth 210 toward the left side. Thus, when the game ball rolls to the left along the upper surface of the open / close door 220 without winning the grand prize opening 210, the game ball is guided to the left by the left guide plate 200b, and the left guide plate It falls from the left end portion of 200b and rolls toward the out port 100a.

The plunger 232 is fitted in the solenoid 231a through the front wall opening 231b of the rectangular housing 231 so as to be coaxially slidable. The plunger 232 has a T-shaped protrusion 232a with a vertical cross section. And protrudes rightward from the front wall opening 231b of the rectangular casing 231. The vertical section T-shaped projecting portion 232a includes a distal end portion of the plunger 232 and a disc-shaped head portion 232b that is coaxially and tiltably supported by the distal end portion.

  Thus, the plunger 232 slides into the solenoid against the coil spring under the attractive force of the solenoid 231a, and is released from the attractive force of the solenoid by demagnetizing the solenoid 231a. Then, it slides toward the front wall opening 231b side of the rectangular casing 231 under the bias by the coil spring. The coil spring is disposed in the solenoid 231a so as to bias the plunger 232 to the right.

  The rotating member 230b is supported in the assembly hole portion of the game board 10 so as to face the T-shaped protruding portion 232a of the plunger 232 from the right side.

  The rotating member 230 b includes a base 233, a U-shaped plate portion 234 that extends upward from the base 233, and a pin 235. The base 233 is positioned below the T-shaped protrusion 232a of the plunger 232 and perpendicular to the sliding direction of the plunger 232 at its axis (see the dashed line 233a in FIG. 5). It is supported in the assembly hole portion of the game board 10 so as to be rotatable in the left-right direction (sliding direction of the plunger 232).

  The U-shaped plate portion 234 extends upward from the base portion 233, and this U-shaped plate portion 234 extends from the connecting portion 234a to the left and right arm portions 234b to the left to form a U shape. Is formed. The pin 235 is supported between the front and rear arm portions 234b so as to be parallel to the connecting portion 234a in the U-shaped plate portion 234.

  The thus configured rotating member 230b is connected to the special prize opening actuator 230a as follows.

  In other words, the plunger 232 of the prize winning opening actuator 230a is inserted between the front and rear arm portions 234b of the U-shaped plate portion 234 at the vertical cross-section T-shaped projecting portion 232a, and the disc-shaped head portion 232b. Accordingly, the pin 235 and the connecting portion 234a are sandwiched so as to be relatively tiltable with respect to the U-shaped plate portion 234.

  As a result, in the rotating member 230b, the U-shaped plate portion 234 is pulled leftward by the pin 235 as the plunger 232 slides into the rectangular housing 231 and the shaft 233a is used as an axis. The base 233 is rotated counterclockwise, and the plunger 232 is pushed to the right by the connecting portion 234a as the rectangular casing 231 slides to the right. As a shaft, it rotates clockwise together with the base 233 (see FIGS. 5 and 6).

  The interlocking member 230c is connected to the rotating member 230b so as to rotate in conjunction with the rotation, and the interlocking member 230c is configured by an upper wall portion 236 and a lower wall portion 237. (See FIGS. 5 to 7).

  Here, the upper wall portion 236 includes a front-rear direction wall portion 236a and a left-right direction wall portion 236b that is bent in an L shape toward the left from the rear end portion of the front-rear direction wall portion 236a. . Thus, in the upper wall portion 236, the front-rear direction wall portion 236a is supported along the front-rear direction so as to face the rotating member 230d (described later) from the right side, and the left-right direction wall portion 236b is In addition, it is assembled in a concave notch (see FIG. 6) formed in the front portion of the base 233 of the rotating member 230b. Thereby, the interlocking member 230c is integrally connected to the rotating member 230b, and rotates together with the rotating member 230b in the counterclockwise or clockwise direction.

  The lower wall portion 237 includes a front-rear direction wall portion 237a and upper and lower side protruding wall portions 237b, 237c. The lower wall portion 237 is formed by the front-rear direction wall portion 237a of the front-rear direction wall portion 236a. It extends downward from the front end.

  As shown in FIG. 5, the upper and lower side protruding wall portions 237 b and 237 c are positioned in parallel with a space in the vertical direction and protrude leftward from the front and rear direction wall portion 237 a. 237b and 237c face the rotating member 230d from the right side.

  As shown in FIG. 5, the rotating member 230 d includes a rotating shaft 238 and a lever 239 extending from the rotating shaft 238. The rotation shaft 238 is rotatably supported by the lower end portion of the front edge of the front wall of the rectangular housing 231 so as to be parallel to the axis of the plunger 232 of the prize winning opening actuator 230a. The shaft 238 faces the interlocking member 230c from the left side at the right end thereof.

  As shown in FIG. 5, the lever 239 has a base portion 239a, both lever portions 239b, 239c, and a pin 239d. The lever 239 is formed in the radial direction from the outer peripheral portion of the rotating shaft 238 at the base portion 239a. It extends toward the.

  Here, as shown in FIG. 5, the lever portion 239b is extended upward from the left side portion of the base portion 239a in a convex curved shape toward the front, and the lever portion 239b has an extended end thereof. Are connected to a connecting hole portion 223 formed at an intermediate portion in the left-right direction of the opening / closing door 220 so as to be relatively tiltable in the front-rear direction. Thereby, the lever part 239b moves the opening / closing door 220 forward along the upper ends of the left and right side walls 212, 213 of the special winning opening 210 by tilting forward. Further, the lever portion 239b tilts backward to move the open / close door 220 rearward along the upper end portions of the left and right side walls 212, 213 of the prize winning opening 210.

  The lever portion 239c is bent and extended forward from the right end portion of the base portion 239a in an L shape, and the lever portion 239c tilts in the same direction as the lever portion 239b with the rotation shaft 238 as an axis. To do.

  The pin 239d protrudes rightward from the front extending end portion of the lever portion 239c and is inserted and engaged between the upper and lower protruding wall portions 237b and 237c of the rotating member 230c so as to be capable of relative tilting in the vertical direction. Yes.

  The lever portion 239c configured as described above is pushed downward by the upper protruding wall portion 237b by the pin 239d in accordance with the clockwise rotation of the rotating member 230c, and together with the lever portion 239b, the game board 10 Tilt toward the front of the. This means that the open / close door 220 closes the special winning opening 210.

  Further, the lever portion 239c is pushed upward by the lower protruding wall portion 237c by the pin 239d as the rotating member 230c rotates counterclockwise, and together with the lever portion 239b, the game board 10 Tilt toward the back. This means that the open / close door 220 opens the special winning opening 210.

  Moreover, the pachinko gaming machine includes a control device 300 as shown in FIG. The control device 300 is connected between the start winning port sensor S1, the left and right side gate sensors S2, S3, the electric chew winning port sensor S4 and the big winning port sensor S5, and the electric chew actuator 73 and the big winning port actuator 230a. (See FIG. 8).

  The start winning port sensor S1 is provided in the start winning port 61 of the start chucker 60, and this start winning port sensor S1 detects the winning of the game ball for each game ball winning in the start winning port 61. . For each detection, a predetermined number of prize balls are paid out, a big win lottery is made, and the special symbol display unit 113 displays a variation of the special symbol.

  The left gate sensor S2 is provided in the left through gate 80, and the left gate sensor S3 detects the passing game ball for each game ball passing through the left through gate 80. The right gate sensor S3 is provided in the right through gate 80, and the right gate sensor S3 detects the passing game ball for each game ball passing through the right through gate 80.

  The electric-chu winning port sensor S4 is provided in the electric-chu winning port 71 of the electric tulip 70, and this electric-chu winning port sensor S4 is provided for each game ball that wins the electric-chu winning port 71 via the electric tulip 70. The winning of the game ball is detected. For each detection, a predetermined number of prize balls are paid out, a big win lottery is made, and a special symbol change display is made by the special symbol display 113.

  The big prize opening sensor S5 is disposed in the big prize opening winning passage formed through the rear opening surface of the attacker 200, and the big winning prize sensor S5 is a game passing through the big winning prize winning passage. The ball is detected as a winning game ball to the big winning opening 210.

  The control device 300 is composed of a microcomputer, and the control device 300 executes a control program according to a predetermined flowchart (not shown). Thus, during this execution, the control device 300 performs the electric Chu actuator based on the detection output of the start winning port sensor S1, the left gate sensor S2, the right gate sensor S3, the electric chew winning port sensor S4, or the big winning port sensor S5. 73 or a calculation process required for controlling the special winning opening actuator 230a.

  In the first embodiment configured as described above, when the pachinko gaming machine is in an operable state by turning on its power, the control device 300 is in an operating state. Accordingly, the control device 300 repeatedly executes the control program according to the predetermined flowchart.

  At this time, in the attacker 200, it is assumed that the open / close door 220 is in a state where the special winning opening 210 is closed. Therefore, the special winning opening actuator 230a slides the plunger 232 toward the front wall opening 231b side of the rectangular housing 231 under the demagnetization of the solenoid 231a and the bias by the coil spring. As shown in FIG. 5, the rotating member 230b is rotated clockwise about the shaft 233a, and the interlocking member 230c is rotated clockwise together with the rotating member 230b. Yes, the rotating member 230d is in a state in which the opening / closing door 220 is moved forward under the clockwise rotation state of the interlocking member 230c, and the big prize opening 210 is closed by the opening / closing door 220. It is in a state (see FIGS. 4 and 5).

  Thus, when the player starts the game by the pachinko gaming machine, if the player operates the left hand of the operation handle H of the pachinko gaming machine, the game balls are sequentially fired by the ball launching device and guided by the guide rail 20. And is guided into the game area 12 and further rolls downward on the left side of the annular center structure 30.

  In this way, in the process in which each game ball rolls downward on the left side of the annular center structure 30 in sequence, several game balls of the game balls are sequentially started to the start chucker. When winning 60 start winning holes 61, winning of each game ball is sequentially detected by the start winning hole sensor S1. Accordingly, the big hit lottery is sequentially performed based on each detection output of the start winning prize sensor S1. In addition, in the process in which the jackpot lottery is sequentially performed, the special symbol display 113 displays the special symbols in a variable manner. In addition, when the next jackpot lottery is made during this variation display, the variation display by the special symbol display unit 113 of the special symbol accompanying this will be displayed on the basis of the hold display by the special symbol reservation unit 114. It is held until the end of the special symbol change display.

  In any of the jackpot lotteries performed sequentially as described above, the jackpot lottery result is assumed to win “long hit”, “short hit” or “small hit”. Here, “long win” and “short win” are included in the jackpot, but “long win” is a win for placing the gaming state of the pachinko gaming machine in the “long hit gaming state”. “Win” is a win for putting the gaming state of the pachinko gaming machine into the “short winning gaming state”. The “small hit” is a hit for setting the gaming state of the pachinko gaming machine to the “small hit gaming state”.

  Here, the “game state per long” is a predetermined long number of times (for example, 30 (seconds)) for each round over a predetermined number of rounds (for example, 15 (times)) in the attacker 200 for each round. A game corresponding to a pattern (open pattern per long) that is opened for a period of time or until the number of winning game balls for the grand prize opening 210 reaches a predetermined number (for example, 9 (number)). State. For this reason, in this “long hit gaming state”, the possibility of winning a game ball into the big winning opening 210 increases, and the player can expect to acquire many prize balls.

  In addition, the “short win gaming state” means that in the attacker 200, a predetermined number of rounds (for example, 15 (times)) is held for a predetermined short time (for example, 0.1 (second)) for each round. ) Or until the number of winning game balls with respect to the big prize opening 210 reaches a predetermined number (for example, 9 (pieces)), this pattern corresponds to a pattern (open pattern per short). A gaming state. For this reason, in this “short win game state”, the possibility of winning the big winning opening 210 is low, and it is difficult for the player to acquire many prize balls.

  Similarly to the “short win game state”, the “small win game state” is defined by the attacker 200 for a predetermined number of times (for example, 15 (times)) for each predetermined time (for example, 15 (times)). (For example, 0.1 (seconds)) or a pattern in which the special winning opening 210 is opened until the number of winning game balls with respect to the special winning opening 210 reaches a predetermined number (for example, 9 (pieces)). It is a gaming state corresponding to (small hit release pattern). For this reason, in this “small winning game state”, as in the “short winning game state”, the possibility of winning in the big winning opening 210 is low, and it is difficult for the player to acquire many prize balls. As described above, the “small hit gaming state” is the same gaming state as the “short hit gaming state”. Therefore, the player distinguishes between the “small hit gaming state” and the “short hit gaming state”. It is difficult to do.

  Therefore, as described above, when the result of the big hit lottery becomes “long win”, the gaming state of the pachinko gaming machine is controlled by the control device 300 to the “long win gaming state”. In other words, the control device 300 controls the drive mechanism 230 so that the gaming state of the pachinko gaming machine is set to the “long hit gaming state”. This means that the driving mechanism 230 is driven to open the special winning opening 210 in the above-described long-opening pattern for every 15 rounds.

  In such a drive, when the special winning opening actuator 230a is excited in the first round by the solenoid 231a for 15 rounds for each round for the predetermined long time 231a. The jar 232 is attracted by the solenoid 231a and slides into the rectangular casing 231 against the coil spring.

  Then, the rotating member 230b is pulled by the plunger 232 as it slides into the rectangular housing 231 and rotates counterclockwise as shown in FIG. Turn counterclockwise. Accordingly, the rotating member 230d is pushed upward by the lower protruding wall portion 237c at the pin 239d as the interlocking member 230c rotates in the counterclockwise direction. And the door 220 is moved backward. As a result, the open / close door 220 opens the special winning opening 210 for the predetermined long time (see FIGS. 6 and 4).

  Thus, when the open / close door 220 is thus opened, the player operates the operation handle H to the right. Accordingly, the game balls are sequentially fired between the inner rail portion 21 and the outer rail portion 22 with the maximum hitting force of the operation handle H, and the center structure along the inner peripheral surface of the outer rail portion 22. Roll to the right side of the object 30.

  Each game ball that rolls in this way rolls downward along the board surface 11 on the right side of the annular center structure 30. In such a state, since the special winning opening 210 is maintained in the open state for the predetermined long period of time as described above, on the right side of the annular center structure 30 as described above, downward along the board surface 11. Each game ball that rolls in the direction easily wins the big winning opening 210 sequentially. Then, each of these game balls is sequentially detected by the big prize opening sensor S5. Along with this, a predetermined number of prize balls are repeatedly paid out for each detection by the special winning opening sensor S5.

  In such a state, when the predetermined long time elapses or the number of prize balls to be paid out reaches a predetermined number, the drive mechanism 230 is driven and controlled by the control device 300 so as to close the special winning opening 210. .

  When the special winning opening actuator 230a is demagnetized by the solenoid 231a, the plunger 232 is released from the attraction by the solenoid 231a and is biased by the coil spring toward the rotating member 230b. Slide.

  Then, the rotating member 230b is pushed by the plunger 232 and rotates clockwise as shown in FIG. 5 to rotate the interlocking member 230c in the clockwise direction. Along with this, the rotating member 230d is pushed downward by the upper protruding wall portion 237b at the pin 239d as the interlocking member 230c rotates in the clockwise direction, and away from the big prize opening actuator 230a. And the door 220 is moved forward. For this reason, the opening / closing door 220 approaches the window glass FD2 of the front door FD at the front edge portion 224 (see FIG. 10).

  In such a process, the game ball M falling along the board surface 11 of the game board 10 is, for example, as shown in FIG. 9 or 10, the left end of the front edge 224 of the door 220, the window glass FD2, When the game ball M is sandwiched between the top end of the left side wall 212 of the prize winning opening 210, the game ball M is sandwiched between the left end of the front edge 224, the window glass FD2, and the top end of the left side wall 212. Become. Therefore, the game ball M is apparently sandwiched between the left end portion of the front edge portion 224 of the open / close door 220, the window glass FD2, and the upper end portion of the left side wall 212 of the special winning opening 210 without falling. Will remain.

  Here, as described above, the front edge portion 224 of the opening / closing door 220 is linearly inclined backward from the left end portion to the right end portion. For this reason, the front edge part 224 of the opening / closing door 220 is separated from the window glass FD2 as it approaches the right end part from the left end part. In addition, as described above, the opening / closing door 220 moves forward under the drive of the drive mechanism 230, so that the interval between the front edge 224 of the opening / closing door 220 and the window glass FD2 is gradually reduced.

  For this reason, the game ball in the state of being sandwiched as described above is moved to a wider interval portion of the interval between the left end portion of the front edge portion 224 and the window glass FD2 by the opening / closing door 220 as it advances. It is pushed toward.

  In such a process, the game ball M moves from the left end side to the right end side of the front edge portion 224 while moving downward by its own weight, and is instantaneously released from the sandwiched state as shown in FIG. As indicated by 12, it falls into the grand prize winning opening 210. At this time, since the space between the front edge of the bottom wall 211 of the big winning opening 210 and the window glass FD2 is smaller than the outer diameter of the gaming ball, the gaming ball inevitably falls into the big winning opening 210. To do. For this reason, the open / close door 220 can smoothly advance toward the window glass FD <b> 2 under the instantaneous release from the sandwiched state, and can properly close the special winning opening 210.

  Thereafter, in the remaining rounds, the open / close door 220 is opened and closed in the same manner as described above. However, as described above, the game balls are sandwiched in the advance process of the open / close door 220 in the remaining rounds. Even if it occurs between the upper end portion of the left side wall 212 of 210 and the left end portion of the front edge portion 224 of the door 220 and the window glass FD2, this pinching is instantly eliminated as described above, and the door 220 is opened. However, the big winning opening 210 is properly closed for each round.

  In addition, when the result of the big hit lottery is “short win” or “small win” as described above, the gaming state of the pachinko gaming machine is set to “short win game state” or “small win game” by the control device 300. Controlled to "state". In other words, the control device 300 controls the drive mechanism 230 so that the gaming state of the pachinko gaming machine is set to the “short hit gaming state” or the “small hit gaming state”. This is because the driving mechanism 230 is driven to open the big winning opening 210 in the above-described short hit release pattern every 15 rounds in the “short win gaming state”. In the “winning game state”, it means that the big winning opening 210 is driven to open in the above-described small hitting opening pattern every 15 times.

  In such driving, the open / close door 220 is driven to open and close the big prize opening 210 as described above, but the time for opening the big prize opening 210 to be in the open state is a short hit opening pattern or Since the small hit release pattern is much shorter than the long hit release pattern, it is difficult for the game ball to win the big winning opening 210.

  Further, when closing the special winning opening 210 as described above, the open / close door 220 is driven by the drive mechanism 230 in the same manner as described above and repeatedly advances. In each of the repetitive advancement processes of the door 220, as described above, the game ball M moves to the left end of the front edge 224 of the door 220, the window glass FD2, and the upper end of the left side wall 212 of the big prize opening 210. Even if the game ball M is pinched between the two parts, the game ball M is released from the pinched state and falls into the big winning opening 210 as described above. For this reason, even in the “short win game state” or “small win game state”, the open / close door 220 moves smoothly and closes the special winning opening 210 properly in the same manner as described above under the elimination of the pinching. be able to.

  Further, as described above, in the process in which each game ball rolls downward on the left or right side of the annular center structure 30 sequentially, the game ball does not reach the start winning opening 61. When the left and right through gates 80 are sequentially passed, these game balls are sequentially detected by the left gate sensor S2 or the right gate sensor S3.

  Accordingly, the normal symbol lottery is sequentially performed based on the detection outputs of the left gate sensor S2 or the right gate sensor S3. In addition, in the process in which the normal symbol lottery is sequentially performed, the normal symbol display unit 111 variably displays the normal symbol. In addition, when the next normal symbol lottery is performed during the variation display, the variation display by the normal symbol display unit 111 of the normal symbol accompanying this will be preceded by the hold display by the normal symbol hold unit 112. It is held until the end of the fluctuation display of normal symbols.

  Thus, when any of the above-described normal symbol lotteries is won, the control device 300 drives the electric Chu actuator 73. Accordingly, the electric tulip 70 is driven by the left and right blade members 72 so that the electric chew winning opening 71 is intermittently released by the electric chew actuator 73.

  In such a state, it becomes easy for a game ball that rolls downward in the center of the board surface 11 of the game board 10 to win the electric chew winning slot 71. Accordingly, each time the game balls are sequentially won in the electric chew winning slot 71, the game balls are sequentially detected by the electric chew winning slot sensor S4. Then, each time the electric chew winning hole sensor S4 is detected, a predetermined number of prize balls are paid out, a big winning lottery is made, and special symbols are variably displayed on the special symbol display 113. In addition, when the variation display of the special symbol has already been performed for the variation display, the special symbol retention unit 114 displays the suspension display of the variation display of the special symbol.

  As described above, in the process in which the big win lottery is made every time the electric chew winning hole sensor S4 is detected, if the result of the big hit lottery becomes a long win, short win or small win, the attacker 200 Under the control of the control device 300, the “long hit release pattern” as described above. Opening and closing based on the “short hit opening pattern” or “small hit opening pattern”.

  Then, in the process in which the door 220 advances so as to close the special winning opening 210 as described above, the game ball is moved to the left end portion of the front edge 224 of the door 220 and the window glass FD2 as described above. And the upper end of the left side wall 212 of the prize winning opening 210, the game ball is based on the above-described inclined shape of the front edge 224 of the door 220. Similarly, it is released from the sandwiched state and falls into the big winning opening 210.

  For this reason, the open / close door 220 moves smoothly under the release of the game ball from the sandwiched state, and appropriately closes the big prize opening 210.
