A starting port 6 is provided below the symbol display device 5 where the inflow of game balls triggers symbol variation, and further below that is a large winning port 7 which is a variable winning device.

  The big winning opening 7 is provided with a horizontally long and substantially rectangular opening 12 which is arranged to face the board surface 2 in the approximate center of the panel 11 and wins the falling inflow of the game ball as an opportunity to win a prize. It has.

  As shown in FIG. 2, the door 13 is divided into a main door 14 and a sub door 15 that can be operated separately.

  The main opening / closing door 14 is formed in a horizontally long plate shape so as to close most of the opening 12 except for the left and right side end portions and the upper end portion thereof when standing, and a weight 16 is provided at the center of the lower portion of the front surface. ), Pins 17a and 17b, which are supported on the panel 11 side and serve as rotation fulcrums, are provided at the lower ends of the left and right side surfaces in an upright state, and a locking lever 18 is provided at the bottom right end. A first solenoid 19 (first driving means) is disposed behind the locking lever 18, and is spring-biased in a direction in which the locking lever 18 is pressed and the first solenoid 19. Thus, a pressing lever 20 that can be driven in the pressing release direction is provided.

  When the first solenoid 19 is not energized, the main opening / closing door 14 stands up as shown in FIG. 3 (a) when the locking lever 18 is pushed by the pressing lever 20, and as shown in FIG. 2 (d). When the first solenoid 19 is energized, the pressure is released and the weight is rotated by the weight of the weight 16, as shown in FIG. 3B. As shown in FIG. 2, the game ball is moved forward, and the game ball is received and guided into the opening 12 as shown in FIG. 2B (conversion from the closed state to the open state).

  As shown in FIG. 4, the sub-opening / closing door 15 has a substantially half-opened fan shape, and is provided with pins 21 a, 21 b that are supported on the panel 11 side and are pivotal fulcrums, respectively. It consists of a pair of left and right guide plates 23a, 23b provided with weights 22a, 22b on the side, and a single rod 24 that connects the base portions of the weights 22a, 22b of the pair of guide plates 23a, 23b. As shown in FIG. 2, a pair of guide plates 23a, 23b are fitted between the main opening / closing door 14 at both left and right end portions of the opening 12, and can be rotated with pins 21a, 21b as fulcrums. In conjunction with the rotation of the doors 23a and 23b, the rod 24 is configured to rotate outside the rotation locus of the upper edge of the main door 14. As shown in FIG. 4, a locking lever 25 is provided in the vicinity of the pin 21a of the left guide plate 23a, and a second solenoid 26 (second driving means) is provided behind the locking lever 25. And a pressing lever 27 that is spring-biased in the direction of pressing the locking lever 25 and that can be driven in the pressing release direction by the second solenoid 26.

  When the second solenoid 26 is not energized, the sub-opening / closing door 15 stands up as shown in FIG. 4A when the locking lever 25 is pushed by the pressing lever 27, as shown in FIG. 2A. The rod 24 closes the opening 12 outside the rotation trajectory of the upper edge of the main opening / closing door 14 (conversion from the open state to the closed state), and when the second solenoid 26 is energized, the pressure is released and the weight It rotates with the weight of 22a, 22b, moves forward as shown in FIG.4 (b), and becomes the open state which opens the opening 12 as shown in FIG.2 (c) (conversion from a closed state to an open state). The sub-opening / closing door 15 prevents a spilled game ball in which the pair of left and right guide plates 23a, 23b are guided by the main opening / closing door 14 in the open state.

  The open / close door 13 is divided into the main open / close door 14 and the sub open / close door 15 that can be operated separately as described above, and the main open / close door 14 can be turned up and down by a first solenoid 19 to open the opening 12. It can be converted into a closed state in which most parts are closed and an open state in which the game ball is received forward and guided into the opening 12, and the sub-opening / closing door 15 can be turned up and down by the second solenoid 26, and the bar 24 is opened and closed mainly. It is possible to convert between a closed state in which the opening 12 is closed outside the rotation trajectory of the upper edge of the door 14 and an open state in which the opening 12 is opened forward and controlled by the first solenoid 19 and the second solenoid 26. The entire open / close door 13 is in the closed state shown in FIG. 2A (the main open / close door 14 and the sub open / close door 15 are both closed), and in the transient open state shown in FIG. 2B (the main open / close door 14 is open, The open / close door 15 is closed), and the open state shown in FIG. Closing 14 and the auxiliary door 15 are both open state), and can have four states of (transient closed state shown in d) (main door 14 is closed, the sub door 15 is opened).

  In this pachinko machine, when the game ball wins the starting opening 6, the symbol display device 5 starts symbol variation, stops and displays the symbol determined after a predetermined time, and the symbol that is stopped and displayed is a jackpot symbol. A big hit is generated, and the first solenoid 19 and the second solenoid 26 of the big winning opening 7 are energized, whereby the main door 14 and the sub door 15 are opened (from the closed state to the open state). ), The opening 12 is opened for a predetermined time, and the game ball can be won in the big winning opening 7.

  At that time (at the time of conversion from the closed state to the open state), the first solenoid 19 and the second solenoid 26 close the sub open / close door 15 with respect to the timing of conversion from the closed state of the main door 14 to the open state. The timing of conversion from the state to the open state is delayed by a predetermined time (for example, 1 second), and the door 13 as a whole is in the closed state shown in FIG. 2A (the main door 14 and the sub door 15 are both closed). (B) through the transient open state (the main door 14 is open, the sub door 15 is closed), and the open state (the main door 14 and the sub door 15 are both open) shown in (c). (State).

  When a predetermined number (for example, 10) of winning balls are detected by a detection switch (not shown) of the big winning opening 7, the first solenoid 19 and the second solenoid 26 are deenergized. 14 and the sub-opening / closing door 15 are closed (conversion from the open state to the closed state), the opening 12 is closed, and the jackpot ends.

  At that time (at the time of conversion from the open state to the closed state), the first solenoid 19 and the second solenoid 26 open the sub door 15 with respect to the timing of conversion from the open state of the main door 14 to the closed state. The timing of conversion from the state to the closed state is delayed by a predetermined time (for example, 1 second), and the open / close door 13 as a whole is in the open state shown in FIG. 2C (the main open / close door 14 and the sub open / close door 15 are both open). From (a), the closed state (the main door 14 and the sub door 15 are both closed) is passed through the transient closed state (the main door 14 is closed and the sub door 15 is open). (State).

  In this way, the open / close door 13 is divided into the main open / close door 14 and the sub open / close door 15, and the timing of conversion from the closed state to the open state and the conversion timing from the open state to the closed state are set as the main open / close door 14. And the sub-opening / closing door 15 cause a problem that the game ball is caught between the upper edge of the opening 12 by the opening / closing door 13 when the opening / closing door 13 is converted from the open state to the closed state, as will be described below. This solves the problem of pinching with the glass plate during conversion from the closed state to the open state.

  First, at the time of conversion from the open state to the closed state, as shown in FIG. 5A, the main opening / closing door 14 and the sub opening / closing door 15 are both open so that the game ball P can be won (( c), when only the main door 14 is to be closed first (at the time of transition to the state of FIG. 2D), as shown in FIG. 5B, the main door is opened. A game ball may be sandwiched between the upper edge of the opening 14 and the upper edge of the opening 12. In this case, the auxiliary opening / closing door 15 is delayed by a predetermined time (for example, 1 second) from the closed state conversion of the main opening / closing door 14. When converted to the closed state, as shown in FIG. 5C, the game ball P that has been sandwiched is pushed by the bar 24 of the sub opening / closing door 15 and pushed into the opening 12.

  Further, at the time of conversion from the closed state to the open state, as shown in FIG. 6A, the main opening / closing door 14 and the sub opening / closing door 15 are both closed (the state shown in FIG. 2A). ), When the big hit occurs and only the main opening / closing door 14 is going to open first (at the time of transition to the state of FIG. 2 (b)), as shown in FIG. 6 (b), the main opening / closing In some cases, the game ball P is sandwiched between the upper edge of the door 14 and the glass plate 30. In this case, the sub-opening / closing door is delayed by a predetermined time (for example, 1 second) from the open state conversion of the main opening / closing door 14. When 15 is converted to the open state, as shown in FIG. 6C, the game ball P that has been sandwiched is pushed by the bar 24 of the sub opening / closing door 15 and dropped downward.

  In this way, it is possible to immediately release the game ball from being caught by the open / close door 13 when the open / close door 13 is converted from the open state to the closed state and when the open / close door 13 is converted from the closed state to the open state. In addition, the open / close door 13 separates into the main open / close door 14 and the sub open / close door 15 and moves separately, thereby increasing visual interest.
