These pin engagement elongated holes 73 are in the rolling direction of the game ball on the upper surface of the open / close door 71 (the direction of the arrow H1 shown in FIG. 5, FIG. 7, etc., hereinafter referred to as “the on-door ball rolling direction H1”). The upper surface pins 90 </ b> B of a pair of rotation link members 90, 90 described later provided in the power conversion mechanism 99 are engaged with the pin engagement long holes 73.

  As shown in FIG. 5, a door notch 72 is formed at the lower end of the door upper ball rolling direction H <b> 1 in the open / close door 71 by notching the leading edge to the side away from the door facing wall 48. Specifically, the inner side surface 72S (see FIG. 7) at the upper end of the door cutout 72 is a linear movement direction in the open / close door 71 (the direction of the arrow H2 shown in FIGS. H2 ") and cut at a right angle from the front end surface 71S of the entire opening / closing door 71, and the rear surface 72A of the door notch 72 is in the direction of rolling on the upper sphere H1 as shown in FIG. It inclines so that it may leave | separate from the door opposing wall 48 as it goes below. As shown in FIG. 9 (B), the door notch 72 has a size approximately equal to the diameter of the game ball in the on-door ball rolling direction H1, and the door notch 72 The size is about 1/4 to 1/2 of the diameter. Moreover, as shown in FIG. 5, the front end surface 71S of the entire opening / closing door 71 and the back surface 72A of the door cutout 72 are both inclined to face obliquely downward and forward. In addition, at the corner between the rear surface 72A of the door notch 72 and the lower end surface of the door upper ball rolling direction H1 in the open / close door 71, a lower end opening edge of the upper prize winning port 61 in the door upper ball rolling direction H1. A stepped portion 74 is provided corresponding to the stepped shape.

  A solenoid 81 corresponding to the “electric drive source” of the present invention is provided on the side of the top step portion 44 with respect to the power conversion mechanism 99. At the center of the solenoid 81, a plunger 82 (see FIG. 7) corresponding to the “linear motion output portion” according to the present invention is inserted, and linearly moves in a direction parallel to the on-door ball rolling direction H1. ing. Further, a coil spring (not shown) that biases the plunger 82 in a direction in which the plunger 82 protrudes from the solenoid 81 is inserted outside the plunger 82, and the plunger 81 is excited by exciting the solenoid 81. When the tip of 82 moves to the solenoid 81 side and the excitation of the plunger 82 is stopped, the tip of the plunger 82 moves to the side away from the solenoid 81 due to the elastic force of the coil spring. Then, the direct movement of the plunger 82 in the on-door ball rolling direction H1 is converted into the front / rear direction of the open / close door 71 by the power conversion mechanism 99 and applied to the open / close door 71, whereby the open / close door 71 is Open and close the winning opening 61.

  The specific configuration of the power conversion mechanism 99 is as follows. That is, the power conversion mechanism 99 includes the linear link member 84 shown in FIG. 7 and a pair of rotary link members 90 and 90 as movable parts, and the linear link member 84 and the rotary link member 90. Thus, a power transmission path between the plunger 82 and the open / close door 71 is configured.

  The linear motion link member 84 has a structure in which a base portion 86 is provided at one end of the linear motion rod 85. The base part 86 has a flat rectangular parallelepiped shape that faces the end face of the solenoid 81, and includes a plunger engagement hole 86A that is open to one side face and the face that faces the solenoid 81 (see FIG. 5). Further, a circular flange 82F protrudes laterally from the tip of the plunger 82, the circular flange 82F is inserted into the plunger engaging hole 86A from the side, and the plunger engaging hole 86A is fixed to the plunger 82. . In addition, on the upper surface and the lower surface of the base portion 86, guide protrusions 86T protrude from the end portions upward and downward from both side surfaces, respectively. The guide projection 86T is engaged with a linear motion guide portion (not shown) provided on the fixed wall portion of the display frame body 40, so that the linear motion link member 84 is restricted from rotating around the axis of the plunger 82. And is positioned at the open position on the solenoid 81 side and the closed position on the opposite side in the linearly movable range.

  The linear movement rod 85 extends in the linear movement direction of the plunger 82 from a position near the rear end on the surface of the base portion 86 opposite to the solenoid 81. Further, pin engagement grooves 87 are respectively provided at the proximal end position and the distal end position in the longitudinal direction of the linear motion rod 85. Each pin engagement groove 87 has a square groove structure that opens in the front-rear direction and upward. Further, a pair of groove facing walls 87 </ b> V and 87 </ b> W rising from the bottom of the pin engaging groove 87 and protruding from the upper surface of the linear moving rod 85 are provided on both sides of the pin engaging groove 87 of the linear moving rod 85. Yes.

  The pair of rotation link members 90 and 90 are parts having the same shape, and include a rotation support shaft 90J that vertically penetrates the rotation plate 90D. Then, each rotation support shaft 90J of the pair of rotation link members 90 is disposed on the front side of the linear motion rod 85, and both ends thereof are rotatably supported by the fixed wall portion of the display frame body 40. .

  An upper surface pin 90B protrudes from a position away from the solenoid 81 from the rotation support shaft 90J in the upper sphere rolling direction H1 of the upper surface of the rotation plate 90D, and the upper surface pin 90B of each rotation link member 90 corresponds to the opening / closing door 71. The pin engagement long holes 73 are engaged. Thereby, when the rotation link member 90 rotates clockwise as viewed from above, the opening / closing door 71 moves directly in the opening direction.

  From the lower surface of the rotating plate 90D, a lower surface pin 90A and a stopper protrusion 90C protrude. The lower surface pin 90A is disposed on the rear side in the door linear movement direction H2 from the rotational support shaft 90J, and the lower surface pin 90A of each rotational link member 90 is received in each pin engaging groove 87 in the linear motion rod 85. Further, as shown in FIG. 8A, the diameter of the lower surface pin 90A is smaller than the width of the pin engaging groove 87, that is, the distance between the groove facing walls 87V and 87W. When the solenoid 81 is in a non-excited state and the linear motion link member 84 is disposed at the closed position, the lower surface pin 90A comes into contact with one groove facing wall 87V on the solenoid 81 side and against the other groove facing wall 87W. It will be in the state which opposes through clearance. In this state, the rotation link member 90 is disposed at the closed position that is one end of the rotatable range, and the opening / closing door 71 is disposed at the closed position that is one end of the linearly movable range.

  The stopper projection 90C moves directly to the other groove facing wall 87W (hereinafter referred to as “stopper / groove facing wall 87W”) with the rotation link member 90 and the linear motion link member 84 disposed at the closed position. It arrange | positions in the position which opposes from the front of the direction H2. The stopper protrusion 90C has an arc shape centered on the rotation support shaft 90J, and has a flat surface facing one end of the stopper / groove facing wall 87W at one end. When the solenoid 81 is in a non-excited state and the linear motion link member 84 is placed in the closed position and an external force is applied to the open / close door 71, as shown in FIG. 90C abuts against the stopper / groove facing wall 87W in the door linear movement direction H2, and the rotation of the rotation link member 90 is restricted, and the open / close door 71 is held in the closed position.

  On the other hand, when the solenoid 81 is excited to move the linear link member 84 from the closed position toward the open position, the stopper / groove facing wall 87W moves through the clearance as shown in FIG. 8B. Only the linear link member 84 moves while the rotation link member 90 is stationary until it contacts the lower surface pin 90A. Accordingly, the stopper / groove facing wall 87W and the stopper projection 90C are displaced in the door upper ball rolling direction H1 and do not face each other in the door linear movement direction H2. Thus, after the stopper / groove facing wall 87W contacts the lower surface pin 90A, the rotation link member 90 rotates as the linear motion link member 84 moves to the open position side, and the rotation link member 90 and the opening / closing The door 71 moves from the closed position to the open position at the other end (the state shown in FIG. 8C).

  That is, the power conversion mechanism 99 operates when power is received from the solenoid 81 side in a state where the linear link member 84, the rotation link member 90, and the open / close door 71 are disposed at the closed position, and from the open / close door 71 side. When receiving power (corresponding to “open driving force” according to the present invention), it does not operate. As a result, an illegal act of applying an external force to the open / close door 71 and opening the upper prize winning opening 61 is prevented. Also,

  In the present embodiment, the groove facing walls 87V and 87W and the lower surface pin 90A correspond to the “first power transmission contact portion” according to the present invention, and the upper surface pin 90B and the pedestal portion 73Z constitute the “second power transmission”. The stopper protrusion 90C corresponds to a “rotation stopper” according to the present invention, and the power conversion mechanism 99 corresponds to a “door opening restriction mechanism” according to the present invention. Further, the upper surface pin 90B and the pedestal portion 73Z corresponding to the “second power transmission contact portion” are arranged at two symmetrical positions which are symmetrical with respect to the center of the on-door ball rolling direction H1 in the open / close door 71. Has been. Thereby, the attitude | position of the opening-and-closing door 71 is stabilized, and the linear motion operation of the opening-and-closing door 71 becomes smooth.

  The opening / closing of the upper prize winning opening 61 is controlled as follows. That is, when the special symbol stops on the main display 35 with a doublet, a CPU (not shown) executes a program for executing a big hit game, and either of the upper prize winning port 61 or the lower major prize winning port 15 is executed. One of them can be selectively selected. For example, when the special symbol is stopped and displayed on the main display 35 with an odd number of eyes, a game ball can be won in the upper large winning opening 61 and cannot be won in the lower large winning opening 15. Further, when the special symbol is stopped and displayed on the main display 35 with an even number of eyes, a game ball cannot be won in the upper large winning opening 61 and can be won in the lower large winning opening 15. Similarly to the lower university prize opening 15, the upper university prize opening 61 has an end condition of whether the upper university prize opening 61 has been opened for 30 seconds or 10 game balls have been won. One round ends when the condition is satisfied.

  Note that the winning of a game ball in one of the upper and lower start winning openings 14A, 14B corresponds to the “win / fail judgment condition” according to the present invention, and the CPU described above executes the program for judgment of success / failure. It functions as a “hit / hit determination unit” according to the invention, and functions as a “hit game execution unit” according to the present invention by executing a program for executing a jackpot game.

  The configuration of the pachinko gaming machine 10 of the present embodiment is as described above, and the operation will be described below. When the operation knob 28 is turned to start the game, game balls are sequentially driven toward the game area YR, and flow down the game area YR at random. At this time, a part of the game balls collide with the top step portion 44 of the display frame body 40 and bounce leftward toward the upper prize winning opening 61 or directly flow down from above to the upper prize winning opening 61. However, since the upper prize winning opening 61 is normally closed by the opening / closing door 71, the flat guide surface 43M1, which is the upper surface of the opening / closing door 71, faces the lower left without entering the upper prize winning opening 61. It rolls, falls from the display frame 40, and flows down toward the lower side of the game area YR. In addition, although the door notch 72 is formed in the open / close door 71, the depth of the door notch 72 is smaller than the diameter of the game ball, so that the game ball enters the upper big prize opening 61 through the door notch 72. I don't have to.

  If any of the game balls flowing down the game area YR wins the start winning opening 14A, 14B, a determination is made. Then, the left, middle, and right special symbols on the display screen 36 are variably displayed and then stopped. If the left, middle, and right special symbols that are stopped and displayed are flat-eyed, As a result, the determination result is displayed. Then, when the special symbol becomes an odd number, the big hit game of opening the upper prize winning opening 61 is executed, the open / close door 71 moves from the closed position to the open position, and retreats to the back of the slit 49, The upper prize winning opening 61 is opened.

  In the jackpot game with the upper university winning opening 61 opened, the end condition of either the opening time of the upper university winning opening 61 has reached 30 seconds or 10 game balls have been won first. In some cases, one round ends and the round is repeated a predetermined number of times. Thus, it becomes possible to enter the upper large winning opening 61, and the prize balls corresponding to the number of the entries are paid out to the upper plate 27A, so that more prize balls, that is, profits than the normal time, can be obtained by the player. To be granted.

  Now, when the open / close door 71 closes at the end of each round, as shown in FIG. 9A, a situation may occur in which the game ball is caught between the open / close door 71 and the door facing wall 48. When the situation where the game ball is sandwiched between the open / close door 71 and the door facing wall 48 continues, the game ball is lifted through the gap between the open / close door 71 and the door facing wall 48 before and after the sandwiched game ball. It becomes an abnormal state to enter the big winning opening 61.

  However, since the front end surface 71S of the open / close door 71 is inclined so as to face obliquely downward and forward, the game ball in contact with the front end edge of the open / close door 71 is guided into the upper prize winning opening 61, and the game ball is The situation sandwiched between the open / close door 71 and the door facing wall 48 is eliminated early.

  And even if the pinching state of the game ball is not canceled by the front end surface 71S of the open / close door 71, in the pachinko gaming machine 10 of the present embodiment, of the front end edge of the open / close door 71, the on-door ball rolling direction H1. Since the door notch 72 is formed by notching the lower end portion, the game ball sandwiched between the door 71 and the door facing wall 48 is guided to the door notch 72 due to the inclination of the door 71, and the door When received by the notch 72, the holding force between the open / close door 71 and the door facing wall 48 is weakened and the game ball is taken into the upper prize winning opening 61.

  At this time, as shown in FIG. 9B, even if a game ball is sandwiched between the rear surface 72A of the door cutout 72 and the door facing wall 48, the depth of the door cutout 72 is larger than the diameter of the game ball. Since it is small, the game ball does not enter the upper prize winning opening 61 from between the front edge of the door 71 that is half-opened corresponding to the “half-open position” according to the present invention and the door facing wall 48. . Thereby, it is possible to suppress abnormal entry of the upper prize winning opening 61.

  In addition, since the depth 72A of the door notch 72 is inclined and the depth of the door notch 72 becomes wider toward the downstream of the upper ball rolling direction H1, the depth 72A of the door notch 72 and the door The game ball sandwiched between the facing wall 48 moves downstream in the door cutout 72, so that the open / close door 71 approaches the door facing wall 48 and more reliably prevents abnormal entry of the game ball. can do.

Further, when the open / close door 71 is in a half-open state, as shown in FIG. 10, the stopper projection 90C and the stopper / groove facing wall 87W are displaced from each other in the on-door ball rolling direction H1 and face each other in the door linear movement direction H2. Therefore, the open / close door 71 is opened by an external force applied from the open / close door 71 side (corresponding to the “open driving force” according to the present invention). As a result, when another game ball comes into contact with the game ball sandwiched between the back surface 72A of the door notch 72 and the door facing wall 48, or a clerk of the game hall opens the front frame 110 to open the door 71. By pushing, the open / close door 71 is moved in the opening direction to eliminate the game balls that are pinched, and the open / close door 71 can be moved to the closed position.
