  The out port 24 is a discharge port for collecting the game balls that have not entered any of the above winning ports at the bottom of the game area 13 and discharging them to the back side of the gaming machine 1.
  Next, the passage route of the game balls in the game area 13 and the relationship between the passage route and the operation mode of the handle lever 4 will be described. A game ball launched into the upper part of the game area 13 by the operation of the handle lever 4 by the player passes through one of the left and right routes of the decorative frame body 14. That is, as shown in FIG. 2, the game ball rolls downward in the game area 13 provided with various winning ports through one of the routes F1 and F2. Rolling the game area 13 downward through the route F1 formed on the right side of the decorative frame 14 is called “right-handed”, and the player handles the route F1 through the route F1. Operating (rotating) the lever 4 is referred to as “right-handed operation”. On the other hand, when the game ball rolls down the game area 13 through the route F2 formed on the left side of the decorative frame 14 is called “left-handed (non-right-handed)”, and the route F2 The operation of the handle lever 4 by the player so as to pass is referred to as “left strike operation (non-right strike operation)”.
  The operation angle of the handle lever 4 is restricted within a predetermined angle range, and the firing solenoid is set so that the “right-handed operation” state is obtained when the handle lever 4 is rotated approximately the maximum angle clockwise within that angle range. The game ball launching mechanism such as is adjusted.
  In the game board 10 of the present embodiment, there is a possibility that a game ball passing through the route F2 may enter the big prize opening 22 due to the arrangement configuration of the decorative frame body 14, the nail 15, the variable prize opening device 9, and other various members. Is low. On the other hand, a game ball passing through the route F1 has a high possibility of entering the grand prize winning port 22. Therefore, when a big hit occurs in the gaming machine 1 and the opening / closing door 23 opens and closes the big prize opening 22, the player rotates the handle lever 4 to the maximum angle in order to enter the big prize opening 22 The right-handed operation state is performed, and the game ball is operated so as to pass the route F1.
  On the other hand, a large number of nails 15, windmills 17, and the like are arranged so that the game ball passing through the route F <b> 2 rolls toward the first start port 19. On the other hand, a game ball passing through the route F <b> 1 is less likely to enter the first start port 19. That is, in the present embodiment, a game ball passing through the route F2 may enter the first start port 19, but a game ball passing through the route F1 may enter the first start port 19. The board structure is extremely low.
  The electric tulip 20 and the second starting port 21 are provided at the lower center of the game area 13, and the game ball will be the first if the electric tulip 20 is opened to the left and right, regardless of whether the route F1 or the route F2 is passed. While there is a possibility of entering the 2 start opening 21, the possibility that the game ball enters the 2nd start opening 21 is low if the electric tulip 20 is closed.
  When a game ball enters the first start port 19 or the second start port 21, a big hit lottery is performed in the gaming machine 1 as described above. There are two types of winnings in the jackpot lottery, “big hit” and “small hit”. Regardless of whether the winning of “big win” or “small win” is won, the gaming machine 1 shifts to a big prize opening game (special game state) in which the big prize opening 22 is opened. However, the number of times the grand prize opening 22 is opened and closed (the number of rounds) in the big prize opening opening game and the opening time per time of the big prize opening 22 are different depending on the type of winning. In other words, the big prize opening game includes a jackpot game when winning a jackpot and a jackpot game when winning a jackpot. In addition, there are two types of “big hit” and “short hit” in “big hit”, and in the big hit game there is also a long hit game in the case of “long win” and a short hit in the case of “short win”. There is a game. This will be described in more detail below.
  When “long win” is set in the case of “big hit”, in the big prize opening game, the opening / closing time for the opening / closing door 23 to open the big prize opening 22 is relatively long (for example, 30 seconds). Etc.). In the “per-long” big prize opening game, if the set opening time per time has elapsed or a predetermined number of balls (for example, nine) are counted during the opening, the big prize opening 22 is opened. The closing round is repeated a predetermined number of times (for example, 15 rounds). Therefore, in the big prize opening opening game corresponding to the long hit game, there is a high possibility that the game ball will enter the big prize opening 22 while the open / close door 23 opens the big winning opening 22, and for the player. Becomes a gaming state that can win many prize balls.
  When “short win” is set in the case of “big hit”, in the big prize opening game, the opening time per opening of the open / close door 23 to open the big prize opening 22 is relatively short (for example, 0. 0). 1 second). And in the “short win” big winning opening game, if the set opening time per time has elapsed or a predetermined number of balls (for example, nine) are counted during the opening, the big winning opening 22 is opened. The closing round is repeated a predetermined number of times (for example, 15 rounds). In the winning game opening game corresponding to the short win game, the opening time for the opening / closing door 23 to open the winning game port 22 is set to a short time during which it is difficult for the game ball to enter, so the winning game port 22 is opened. During this time, there is a low possibility that the game ball will enter the big winning opening 22, and it becomes difficult for the player to obtain many prize balls.
  On the other hand, in the case of “small win”, in the large winning opening opening game, as in the case of “short winning”, the opening time per opening when the open / close door 23 opens the large winning opening 22 is relatively short ( For example, 0.1 second). Then, when the set opening time per time has elapsed or a predetermined number of balls (for example, 9) are counted during the opening, the round for closing the big winning opening 22 is repeated a predetermined number of times (for example, 15 rounds). It is. Accordingly, even in the big winning opening opening game corresponding to the small hit game, the opening time of the big winning opening 22 is set to a short time during which it is difficult for the game ball to enter, as in the case of “short win”. There is a low possibility that a game ball will enter the grand prize winning port 22 while the mouth 22 is open, and it becomes difficult for the player to obtain many prize balls.
  The opening / closing operation of the open / close door 23 in this way is almost the same for the small win game and the short win game. It is an operation mode in which it is difficult to determine which of the 22 opening / closing operations is won.
  As described above, the gaming machine 1 according to the present embodiment corresponds to each starting port on condition that a game ball has entered the first starting port 19 and the second starting port 21 provided in the game board 10. The jackpot determination is performed, and when the jackpot or the jackpot is won, the open / close door 23 is configured to open the jackpot 22 according to the type of the jackpot.

The lamp control board 150 lights various lamps 97 including the frame lamp 6 described above based on an instruction from the presentation control board 130, and drives a production accessory. It is comprised so that the accessory drive part 98 for performing may be controlled.
  In this way, in the gaming machine 1, the operation of each part is controlled by the main control board 100. The main control board 100 controls the gaming state of the gaming machine 1. For example, when the first special symbol or the second special symbol is won in the big win or the small win, the gaming state of the gaming machine 1 is shifted to the big prize opening game, and the gaming state after the big prize opening game is changed Control according to the type of hit.
  FIG. 4 is a state transition diagram showing the transition of the gaming state in the gaming machine 1. This gaming machine 1 mainly has five game states: a normal game state ST1, a special prize opening game state ST2, a time-saving game state ST3, a probability variation game state ST4, and a latent probability variation game state ST5. Among these, the four game states of the normal game state ST1, the short-time game state ST3, the probability variation game state ST4, and the latent probability variation game state ST5 cause the game ball to enter the first start port 19 or the second start port 21. This is a gaming state in which the game is advanced while performing a jackpot lottery. In such a gaming state, as a probability state of winning a jackpot in the jackpot lottery in the gaming machine 1, for example, a normal probability state winning a jackpot with a predetermined probability of about 1/300, and winning a jackpot than the normal probability state There are two states, a high probability state in which the probability of In the illustrated example, the normal gaming state ST1 and the short-time gaming state ST3 are normal probability states, and the probability variation gaming state ST4 and the latent probability variation gaming state ST5 are high probability states.
  On the other hand, the special winning opening open gaming state ST2 is determined from the gaming state when the big winning or the small winning is won in each of the normal gaming state ST1, the short time gaming state ST3, the probability variation gaming state ST4, and the latent probability variation gaming state ST5. The game state in which the open / close door 23 opens and closes the special winning opening 22 is entered.
  When the gaming machine 1 is powered on, the gaming machine 1 is activated as a normal gaming state ST1. In this normal gaming state ST1, the probability of winning a jackpot in the jackpot lottery is a normal probability. Therefore, the player operates the handle lever 4 to cause the game ball to enter the first start port 19 or the second start port 21 and play a game while expecting a big hit. In the normal game state ST1, when a normal symbol is drawn by passing a game ball through the through gate 16a or 16b, the variation time of the normal symbol is set to a relatively long time (for example, 29 seconds). When the normal symbol lottery is won, the opening time for opening the electric tulip 20 is set to a relatively short time (for example, 0.2 seconds). Therefore, in the normal game state ST1, the normal symbol variation time is long, and even when the normal symbol lottery is won and the electric tulip 20 is opened, the open time is short, so the game ball enters the second start port 21. The possibility of doing is low. Therefore, when the gaming machine 1 is in the normal gaming state ST1, the player adjusts the operation angle of the handle lever 4 so that the gaming ball launched into the gaming area 13 is route F2 (left strike) shown in FIG. The game is played with the aim of introducing a game ball into the first starting port 19.
  When a game ball enters the first starting port 19 or the second starting port 21 in the normal gaming state ST1 and wins a big hit or a small hit, the gaming machine 1 will open the big winning port opening game as shown by an arrow A1 in FIG. Transition to state ST2. As described above, the big winning opening game state ST2 includes a small win game when winning a big win and a big win game when winning a big win. The jackpot game includes a long hit game and a short hit game. Of these, the long game is the only game that allows the player to obtain many prize balls. In other games (small hit games and short hit games), it is difficult to obtain many prize balls, and there is a possibility that the number of prize balls is zero. In such a grand prize opening open gaming state ST2, since the big prize opening 22 provided in the lower right part of the gaming area 13 is opened, the player adjusts the operation angle of the handle lever 4 to a substantially maximum angle. The game ball to be launched into the game area 13 is guided to the route F1 (right strike) shown in FIG. 2, and the game is played with the aim of causing the game ball to enter the special winning opening 22. However, in the case of a small hit game and a short hit game, the player does not necessarily perform a right-handed operation.
  The main control board 100 shifts the gaming state to any one of the normal gaming state ST1, the short-time gaming state ST3, the probability variation gaming state ST4, and the latent probability variation gaming state ST5 after the big prize opening opening gaming state ST2 ends. More specifically, when a small hit game is performed, when the big prize opening game state ST2 ends, the game state before that is shifted to. For example, when a small winning game is won in the normal gaming state ST1, when the corresponding small winning game ends, the game is shifted from the big prize opening opening gaming state ST2 to the normal gaming state ST1 as indicated by an arrow A2. On the other hand, when the jackpot game is performed, when the jackpot opening game state ST2 ends, the main control board 100 displays the arrows A3, A4, A5 after the jackpot game according to the type of jackpot. As shown, it is shifted to one of the short-time gaming state ST3, the probability variation gaming state ST4, and the latent probability variation gaming state ST5.
  In the short-time gaming state ST3, when a normal symbol is drawn by passing through the through gate 16a or 16b, the variation time of the normal symbol is set to a relatively short time (for example, 3 seconds). When the normal symbol lottery is won, the opening time for opening the electric tulip 20 is set to a relatively long time (for example, 3.5 seconds). Therefore, in the short-time gaming state ST3, the normal symbol variation time is short, and when the electric tulip 20 is released by winning the normal symbol lottery, the released state continues for a relatively long time, so 2 It becomes easy to enter the starter 21. That is, in the short-time game state ST3, the opening and closing operation of the electric tulip 20 assists the game ball to enter the second start port 21 frequently. Therefore, in the short-time gaming state ST3, the player adjusts the operation angle of the handle lever 4 so that the game ball launched into the gaming area 13 is route F1 (right strike) or route F2 (left strike) shown in FIG. By guiding and passing through the through gate 16a or 16b, the electric tulip 20 is frequently opened, and a game is played with the aim of allowing a game ball to enter the second start port 21. In this case, since the game balls frequently enter the second start port 21 with the assistance of the opened electric tulip 20, the player can play the game without reducing the number of game balls as possessions. . However, as described above, in the short-time gaming state ST3, the probability of winning a jackpot with the first special symbol and the second special symbol is a normal probability.
  Such a short time gaming state ST3 continues until the variable display of the special symbols on the first special symbol display 25c and the second special symbol display 25e is performed a predetermined number of times (for example, 100 times). Then, when the number of times of special symbol variation display becomes a predetermined number, the main control board 100 shifts the gaming state of the gaming machine 1 from the short-time gaming state ST3 to the normal gaming state ST1 (arrow A6 in FIG. 6). When the gaming state shifts from the short-time gaming state ST3 to the normal gaming state ST1, the opening interval of the electric tulip 20 becomes longer and the opening time per time becomes shorter, so that the gaming ball is frequently placed at the second starting port 21. It becomes difficult to enter the ball.
  When the first special symbol or the second special symbol wins the big hit or the small win in the short-time gaming state ST3, as shown by the arrow A7 in FIG. The game proceeds to the winning opening open gaming state ST2.
  In the probability variation gaming state ST4, when a normal symbol is drawn by passing a game ball through the through gate 16a or 16b, the variation time of the normal symbol is set to a relatively short time (for example, 3 seconds). When the normal symbol lottery is won, the opening time for opening the electric tulip 20 is set to a relatively long time (for example, 3.5 seconds). Therefore, in the probability variation gaming state ST4, as in the short-time gaming state ST3, the variation time of the normal symbol is short, and when the electric tulip 20 is released by winning the normal symbol lottery, the game ball is placed in the second starting port 21. It becomes easy to enter the ball. That is, even in the probable gaming state ST4, the opening and closing operation of the electric tulip 20 assists the game ball to enter the second start port 21 frequently. Therefore, in the probability variation gaming state ST4, the player adjusts the operation angle of the handle lever 4 so that the game ball launched into the game area 13 is route F1 (right strike) or route F2 (left strike) shown in FIG. By guiding and frequently passing through the through gate 16a or 16b, the electric tulip 20 is frequently opened, and a game is played with the aim of causing the second starting port 21 to enter the game ball. In this case, since the game balls frequently enter the second start port 21 with the assistance of the opened electric tulip 20, the player can play the game without reducing the number of game balls as possessions. . In the probability variation gaming state ST4, as described above, the probability of winning a jackpot in the first special symbol and the second special symbol is a high probability state higher than the normal probability.
  Such a probability variation gaming state ST4 continues until, for example, the next jackpot occurs in the first special symbol or the second special symbol. Therefore, when the game state after the big winning opening release game shifts to the probability change game state ST4, the player can play the game without reducing the number of game balls that are possessed until the next jackpot. In particular, the probabilistic gaming state ST4 has a high probability of winning the jackpot, so it does not reduce the player's possession so much and is likely to win the next jackpot relatively early. Yes.
  When the first special symbol or the second special symbol is won in the jackpot or the jackpot in the probability variation gaming state ST4, as shown by the arrow A8 in FIG. 6, the main control board 100 wins the corresponding big prize from the probability variation gaming state ST4. Transition to the mouth open gaming state ST2.
  In the latent probability changing game state ST5, as described above, the probability of winning the next jackpot becomes a high probability state higher than the normal probability, but the other game states are the same as the normal game state ST1.
  Here, the difference between the probability variation gaming state ST4 and the latent probability variation gaming state ST5 will be described. When the gaming state of the gaming machine 1 shifts to the probability-changing gaming state ST4, an effect is provided to notify that in the probability-changing gaming state ST4, in the gaming machine 1, the jackpot winning probability has changed to a higher probability than the normal probability. Therefore, when the game state shifts to the probability variation game state ST4, the game state is such that the player can easily grasp that the winning probability in the big hit lottery has shifted to the high probability state. Further, in the probability variation gaming state ST4, since the electric tulip 20 is frequently opened as described above, the player can proceed with the game without reducing the number of possessions. On the other hand, when the gaming state of the gaming machine 1 shifts to the latent probability changing gaming state ST5, in the latent probability varying gaming state ST5, the winning probability of jackpot in the gaming machine 1 is usually changed to a higher probability than the normal probability. Not notified to the player. Therefore, when the game state transitions to the latent probability changing gaming state ST5, the gaming state itself of the gaming machine 1 does not appear to change from the normal gaming state ST1, so it is clear that the player has transitioned to the latent probability varying gaming state ST5. Becomes a gaming state that cannot be grasped. Further, in the latent probability changing game state ST5, since the electric tulip 20 does not release frequently, the player's possession decreases as the game progresses. In the latent probability changing game state ST5, as in the normal game state ST1, the player adjusts the operation angle of the handle lever 4 so that the game ball to be launched into the game area 13 is route F2 (left-hand hit) shown in FIG. ), The game is played with the aim of causing the game ball to enter the first start port 19.
  Such a latent probability changing game state ST5 continues until, for example, the next jackpot occurs in the first special symbol or the second special symbol. For this reason, when the gaming state after the big prize opening opening game shifts to the latent probability changing gaming state ST5, the player will play the game while decreasing the number of possessions until the next jackpot winning. However, as described above, in the latent probability changing game state ST5, since the winning probability of jackpot is higher than the normal probability state, it is more for the player than when the game progresses in the normal game state ST1. It is a gaming state that is likely to win the next jackpot relatively early.
  When the first special symbol or the second special symbol wins the big hit or the small win in the latent probability changing game state ST5, as shown by the arrow A9 in FIG. 6, the main control board 100 responds to it from the latent probability changed gaming state ST5. It shifts to the big prize opening opening game state ST2.
  Next, the variable winning opening device 9 that operates in the special winning opening open gaming state ST2 will be described. FIGS. 5 and 6 are enlarged perspective views showing the variable prize opening device 9 attached to the game board 10. FIG. 5 shows a state where the open / close door 23 closes the big prize opening 22, and FIG. 6 shows the open / close door. 23 shows a state where the special winning opening 22 is opened.
  The variable winning opening device 9 has a large winning opening 22 formed in a concave shape. As shown in FIG. 6, the grand prize winning port 22 includes a winning ball rolling area 22a defined by left and right side walls (side ends) 45 and 46 projecting forward from the board surface of the game board 10, and a winning ball. It is comprised by the entrance 22b to the rolling area | region 22a. As shown by a broken line in FIG. 6, the entrance 22b to the winning ball rolling region 22a is formed in a plane including the upper ends of the left and right side walls 45 and 46 constituting the winning ball rolling region 22a. It is located above the moving region 22a. When a game ball enters the winning ball rolling area 22a through the entrance 22b, the gaming ball becomes a winning ball for the grand prize winning port 22.
  Further, as shown in FIGS. 5 and 6, the variable prize opening device 9 moves forward and backward along the front-rear direction of the game board 10 in the upper part of the winning ball rolling area 22 a of the big prize opening 22, so that the winning ball rolls. A flat opening / closing door 23 that opens and closes the entrance 22b to the region 22a is provided. The flat opening / closing door 23 is held in a state of being substantially perpendicular to the game board surface 10 a of the game board 10.
  The variable prize opening device 9 of the present embodiment is attached to the lower right portion of the game board 10 and is located on the right side of the out port 24. Therefore, the variable prize opening device 9 is configured to roll a game ball that has not entered the big prize opening 22 toward the left side where the out opening 24 is located. Specifically, the flat opening / closing door 23 is provided in an inclined state in which the left end portion is lowered from the right end portion, and moves forward and backward in the inclined state. Further, the upper surface of the left side wall 45 of the winning ball rolling area 22a constituting the grand prize winning port 22 is for rolling a game ball that has not entered the big winning prize port 22 to the left toward the out port 24. The rolling path 42 is inclined downward on the left side. Further, the upper surface of the right side wall 46 of the winning ball rolling area 22a is a rolling path 41 inclined downward to the right in order to roll game balls that have not entered the big winning opening 22 to the right. . A game ball that rolls to the right on the rolling path 41 and falls is guided to a rolling path 43 provided below the special winning opening 22. This rolling path 43 is inclined downward on the left side so as to roll the game ball to the left toward the out port 24 through the back side of the decorative plate 44. In addition, the indicator 25 mentioned above is provided in the lower part of this rolling path 43. FIG.
  In such a variable prize opening device 9, when the gaming state of the gaming machine 1 is a normal game ST1, a short-time game ST3, a probability variation game ST4, or a latent probability variation game ST5, as shown in FIG. The entrance 22b to the winning ball rolling area 22a is closed by advancing to the upper part of the winning ball rolling area 22a constituting the mouth 22. Then, when the gaming machine 1 shifts to the big prize opening game ST2, the variable prize opening device 9 is driven by the main control board 100, and as shown in FIG. 6, the opening / closing door 23 is the entrance 22b to the winning ball rolling area 22a. By opening the state, the special winning opening 22 is opened. In the special prize opening game ST2, as described above, the opening / closing door 23 performs an operation of opening and closing the special prize opening 22 a predetermined number of times.
  FIG. 7 is a front view showing an example of the behavior of the game ball B when the open / close door 23 opens and closes the special winning opening 22, that is, the entrance 22b to the winning ball rolling area 22a. FIG. 7B shows a state in which the open / close door 23 closes the special winning opening 22, and FIG. 7B shows a state in which the special winning opening 22 is opened. In the present embodiment, the variable prize opening device 9 is provided in the lower right portion of the game board 10. Therefore, when the player is performing a right stroke operation on the handle lever 4, the game ball B flows through the route F1 to the upper right of the variable prize opening device 9.
  At this time, as shown in FIG. 7A, if the open / close door 23 is in a state of closing the big winning opening 22, the game ball B does not enter the winning ball rolling area 22a, and therefore the big winning opening 22 is reached. Instead of winning a prize, it rolls to the left along the upper surface slope of the door 23. Then, the rolling ball 42 rolls to the left, and the game ball B is guided to the out port 24. In addition to this, it may fall from the rolling path 41 to the rolling path 43, roll to the left on the rolling path 43, and be guided to the out port 24.
  On the other hand, as shown in FIG. 7B, when the open / close door 23 is in the state of opening the big winning opening 22, the game ball B enters the winning ball rolling area 22a through the opened entrance 22b, It becomes a prize to the big prize opening 22. The game ball B is detected as a winning ball to the big winning port 22 by the big winning port switch 36 when discharged from the discharge port provided in the back of the winning ball rolling area 22a to the back side of the game board 10. Is done.
  FIG. 8 is a diagram illustrating a drive mechanism of the open / close door 23. As shown in FIGS. 8A and 8B, the drive mechanism of the open / close door 23 includes a special prize opening solenoid 37, a rotating member 51, and a movable arm 53. FIG. 8A shows a state in which the big prize opening 22 is closed, and FIG. 8B shows a state in which the big prize opening 22 is opened.
  The open / close door 23 slides in the back direction (+ Y direction) of the game board 10 when the main prize opening solenoid 37 is driven by the main control board 100. The special winning opening solenoid 37 includes a plunger 37a that advances and retreats along the lateral direction. When the plunger 37a is not driven by the main control board 100, the plunger 37a is advanced in the + X direction by an urging means such as a spring provided in the large winning opening solenoid 37. At this time, as shown in FIG. 8A, the open / close door 23 advances in the front direction (−Y direction) of the game board 10 and closes the special winning opening 22.
  When the big prize opening solenoid 37 is driven by the main control board 100, the plunger 37a is drawn inside the big prize opening solenoid 37 against the urging force of the urging means and moves in the -X direction. As a result, the open / close door 23 moves in the rear direction (+ Y direction) of the game board 10 as shown in FIG.
  A disc-shaped locking portion 37b is provided at the tip of the plunger 37a. The locking portion 37b is engaged with a rotating member 51 that rotates about a rotating shaft 51a parallel to the Y axis. When the plunger 37a is pulled inside the special winning opening solenoid 37, the rotating member 51 rotates counterclockwise by a predetermined angle around the rotating shaft 51a. The rotating member 51 is provided with a holding portion 52 having a U-shaped cross section at a position away from the rotation shaft 51a by a predetermined radius. The holding portion 52 rotates along with the rotation of the rotating member 51 around the rotation shaft 51a. Such a rotation operation of the holding unit 52 changes the height position of the holding unit 52.
  The movable arm 53 is rotatable about a predetermined rotation axis 53a parallel to the X axis. The upper end of the movable arm 53 is inserted into a hole 59 provided in the open / close door 23. A peripheral wall standing in the vertical direction is provided around the hole 59 of the open / close door 23, and the upper end of the movable arm 53 moves the open / close door 23 in the front-rear direction by applying a pressing force to the peripheral wall. Let That is, the movable arm 53 moves around the rotation shaft 53a to move the door 23 in the front-rear direction along the Y axis.
  The movable arm 53 has a pin 54 held by the holding portion 52 of the rotating member 51 at a position away from the rotation shaft 53a by a predetermined radius. The pin 54 moves up and down as the rotating member 51 rotates around the rotation shaft 51a and the height position of the holding portion 52 changes. This vertical movement causes the movable arm 53 to rotate about the rotation axis 53a. As described above, when the large winning opening solenoid 37 is driven, the movable arm 53 rotates around the rotation shaft 53a to move the open / close door 23 in the + Y direction as shown in FIG. Open the mouth 22. Further, when the special winning opening solenoid 37 is not driven, the urging means moves the plunger 37a in the + X direction and returns to the original state. Accordingly, the movable arm 53 is moved as shown in FIG. Then, it rotates around the rotary shaft 53a to move the open / close door 23 in the -Y direction, and closes the special winning opening 22.
  As described above, when the open / close door 23 closes the big prize opening 22, the variable prize opening device 9 is not a driving force of the big prize opening solenoid 37 but a spring or the like provided inside the big prize opening solenoid 37. The opening / closing door 23 is moved to the front side (−Y direction) of the game board 10 by the urging force of the urging means.
  Next, the front end portion 23a of the open / close door 23 will be described. As described above, when the open / close door 23 is opened and closed by sliding the open / close door 23 in the front-rear direction, for example, when the front end portion of the open / close door 23 is formed of a vertical wall surface, the open / close door 23 closes the open prize port 22. There is a high possibility that a game ball will be sandwiched between the front end of the open / close door 23 and the transparent glass plate 2a. Therefore, in this embodiment, in order to reduce the possibility that a game ball will be sandwiched between the open / close door 23 and the transparent glass plate 2a, the distal end portion 23a of the open / close door 23 is formed in a sharp shape.
  FIG. 9 is an enlarged cross-sectional view showing the structure of the distal end portion 23 a of the open / close door 23. As shown in FIG. 9, the front end portion 23a of the open / close door 23 has a shape that protrudes forward at only one point, and a tapered surface 23b that is inclined obliquely downward to the normal line is formed below the front end portion 23a. . By forming the tip 23a of the opening / closing door 23 in such a shape, it is possible that a game ball is sandwiched between the opening / closing door 23 and the transparent glass plate 2a when the opening / closing door 23 closes the special winning opening 22. Since there is only a single point of the tip portion 23a, the possibility that the game ball is caught is reduced.
  However, even if the front end portion 23a of the open / close door 23 is shaped as described above, there is a possibility that the game ball is caught at one point of the front end portion 23a. At this time, if the urging force acting on the opening / closing door 23 is strong in order to close the special winning opening 22, two symmetrical points on the front side and the back side of the game ball are the front end portion 23 a of the opening / closing door 23 and the transparent glass plate 2 a. And the door 23 may not be dropped to the big prize opening 22 and the opening / closing door 23 may not be able to close the big prize opening 22. In order to prevent this, in the present embodiment, the urging force of the urging means acting on the open / close door 23 for closing the special winning opening 22 is made as small as possible. Specifically, even if the game ball is sandwiched between one point of the tip 23a and the transparent glass plate 2a, the open / close door 23 acts on the game ball rather than the force of pressing the game ball. The urging force of the urging means is set to a weak force so that the gravity is increased and the game ball is released from the state of being sandwiched by its own weight and falls. As a result, even if a situation occurs in which two front and rear points of the game ball are sandwiched between the front end portion 23a of the open / close door 23 and the transparent glass plate 2a, the game ball is sandwiched by gravity acting on the game ball. It will come out of the state and fall to the big winning opening 22. As a result, the open / close door 23 can close the special winning opening 22 satisfactorily.
  On the other hand, even when the urging force when closing the opening / closing door 23 is reduced as described above, the front end portion 23a of the opening / closing door 23 is transparent glass while the game ball is in contact with the side walls 45, 46 of the big winning opening 22. If a game ball is sandwiched between the board 2a, the game ball may be held at three points around it and may become stable. In particular, in the case of the present embodiment, the game ball falls or rolls from the upper right to the left with respect to the big winning opening 22, so that the upper end of the side wall 45 at the left end of the winning ball rolling area 22a. Then, there is a possibility that three points around the game ball are sandwiched between the front end portion 23a of the open / close door 23 and the transparent glass plate 2a located on the front side thereof. In such a case, even if the urging force of the open / close door 23 is set small as described above, the support force of the game ball by three points may be stronger than the gravity acting on the game ball. A situation may occur in which the open / close door 23 cannot be normally closed without the ball falling. Therefore, in the present embodiment, the structure on the left side of the special winning opening 22 is set as follows in order to satisfactorily prevent such a situation from occurring.
  FIG. 10 is a perspective view showing a state where the decorative board 44 and other members of the variable prize opening device 9 are removed, and FIG. 11 is a front view thereof. When the open / close door 23 is in a closed state, the variable winning award opening device 9 does not have the side wall 45 and the open / close door 23 joined to each other on the left side of the winning ball rolling region 22a but is fixed between them. The gap 47 is provided. That is, the left side end 23c of the front end 23a protruding forward in the open / close door 23 is provided at a position higher than the upper end of the side wall 45 constituting the winning ball rolling region 22a. By providing such a gap 47, it is possible to reduce the possibility of pinching three points of the game ball. This will be described in more detail below.
  FIG. 12 is an enlarged front view showing the left end portion of the winning ball rolling area 22a. As shown in FIG. 12, the side end portion 23c of the front end portion 23a of the open / close door 23 has a predetermined height higher than the upper end portion 45a of the side wall 45 constituting the winning ball rolling region 22a in the vertical and vertical directions (Z-axis direction). It is supported at a position higher by a height H. Here, the predetermined height H is not less than the radius of the game ball and is less than the diameter. In general, since the radius of the game ball is 5.5 mm, 5.5 mm ≦ H <11 mm.
  Further, the side end portion 23c of the front end portion 23a of the open / close door 23 has a predetermined width W from the upper end portion 45a of the side wall 45 by a predetermined width W as shown in FIG. It is provided at a position inside the winning ball rolling area 22a. Here, the predetermined width W is less than the radius of the game ball. Therefore, generally, 0 <W <5.5 mm.
  With such an arrangement, the front end 23a (or the side end 23c) of the open / close door 23 is in contact with the transparent glass plate 2a while the game ball is in contact with the side wall 45 of the winning ball rolling area 22a. Even when a situation in which the game ball is sandwiched between the front and rear doors 23a, the front end 23a of the open / close door 23 contacts the back side of the upper hemisphere of the game ball. Therefore, the urging force acting on the opening / closing door 23 presses the back side of the upper hemisphere portion of the game ball, and generates a force that moves at least downward with respect to the game ball.
  FIG. 13 shows an example in which the game ball B is sandwiched between the upper end 45a of the side wall 45 of the winning ball rolling area 22a, the side end 23c of the front end 23a of the open / close door 23, and the transparent glass plate 2a. FIG. For example, as shown in FIG. 13A, one point of the game ball B in a state where the lowest point P1 of the game ball B is at the same position as the side end 23c of the tip 23a of the open / close door 23 in the X-axis direction. Is in contact with the upper end 45a of the side wall 45, when the open / close door 23 moves in the forward direction (−Y direction), the three points around the game ball B are opened and closed with the upper end 45a of the side wall 45. It is sandwiched between the side end portion 23c of the front end portion 23a of the door 23 and the transparent glass plate 2a. At this time, the side end portion 23c of the front end portion 23a of the open / close door 23 pushes the back side of the upper hemisphere portion of the game ball B forward (see FIG. 13B). The force pushed out forward acts to move the game ball B downward, and is combined with gravity to generate a relatively large downward force.
  At this time, if the lowest point P1 of the game ball B is located inside the winning ball rolling area 22a with respect to the side wall 45, the gaming ball B is a winning ball as shown by an arrow D1 in FIG. It moves toward the rolling region 22a. Then, as the game ball B moves toward the arrow D1, the open / close door 23 advances further forward (−Y direction). When the game ball B falls toward the winning ball rolling area 22a, the open / close door 23 can completely close the entrance 22b to the winning ball rolling area 22a. 22 can be closed normally.
  On the other hand, when the lowest point P1 of the game ball B is located at the upper end 45a of the side wall 45, even if the side end 23c of the open / close door 23 pushes the back side of the upper hemisphere of the game ball B forward, the game The sphere B cannot move downward. In such a case, the urging force acting on the open / close door 23 presses the back side of the upper hemisphere portion of the game ball and generates a force that moves the game ball B in the left direction.
  FIG. 14 shows another case where the game ball B is sandwiched between the upper end 45a of the side wall 45 of the winning ball rolling area 22a, the side end 23c of the front end 23a of the open / close door 23, and the transparent glass plate 2a. It is a figure which shows the example of. For example, as shown in FIG. 14 (a), with the lowest point P1 of the game ball B being in the same position as the upper end 45a of the side wall 45 in the X-axis direction, the open / close door 23 is in the forward direction (-Y direction). As it moves, three points around the game ball B are sandwiched between the upper end 45a of the side wall 45, the side end 23c of the front end 23a of the open / close door 23, and the transparent glass plate 2a. At this time, the side end portion 23c of the front end portion 23a of the open / close door 23 pushes the right side position on the back side of the upper hemisphere portion of the game ball B forward (see FIG. 14B). As shown in FIG. 14 (a), the force pushed forward acts on the right side of the lowermost point P1 of the game ball B on the back side of the game ball B. Act to move to.
  Therefore, the game ball B moves to the left along the rolling path 42 as indicated by an arrow D2 in FIG. Then, as the game ball B moves toward the arrow D2, the open / close door 23 advances further forward (−Y direction). When the game ball B rolls on the rolling path 42, the open / close door 23 can completely close the entrance 22b to the winning ball rolling area 22a. Can be closed normally.
  Thus, when the open / close door 23 closes the big prize opening 22, the variable prize opening device 9 of the present embodiment has the tip 23 a of the opening / closing door 23, the side wall 45 of the big prize opening 22, and the transparent glass plate 2 a. Even if the game ball B is sandwiched between the three points, the game ball B is guided to the winning ball rolling region 22a of the big winning opening 22 without being stabilized in that state, or It is possible to lead to the movement path 42. Therefore, it is possible to satisfactorily prevent a situation in which the game ball B bites and the door 23 cannot be closed normally. As a result, the open / close door 23 can normally close the big prize opening 22 each time the round of the big prize opening game ST2 is finished, and is large even when the big prize opening game ST2 is finished. The winning opening 22 can be normally closed.
  As described above, the variable prize opening device 9 of the present embodiment has the winning ball rolling area 22a defined by the left and right side walls 45 and 46 projecting forward in front of the game board 10, and the winning ball rolling area. The entrance 22b for allowing the game ball to enter the winning ball rolling area 22a is formed by opening the upper part of the game board, and the winning ball is received by the flat opening / closing door 23 that moves forward and backward along the front-rear direction of the game board 10. It is the structure which opens and closes the inlet 22b to the rolling area | region 22a. In the present embodiment, in particular, the side end 23c of the open / close door 23 is provided at a position higher than the upper end of the side wall 45 of the winning ball rolling area 22a in the vertical and vertical directions, and is awarded in the horizontal and horizontal directions. This is a configuration provided inside the winning ball rolling region 22a rather than the upper end of the side wall 45 of the ball rolling region 22a. With such a configuration, even when the open / close door 23 enters the state in which the game ball B is sandwiched between the transparent glass plate 2a, the game ball B can be moved without stabilizing the game ball B in that state. It becomes possible. As a result, the open / close door 23 can normally close the special winning opening 22.
  However, in the variable prize opening device 9 of the present embodiment, the predetermined height H between the side end portion 23c of the front end portion 23a of the open / close door 23 and the upper end portion 45a of the side wall 45 constituting the winning ball rolling region 22a. Is preferably less than the diameter of the game ball (for example, less than 11 mm). Accordingly, it is possible to prevent the game ball from winning the prize winning port 22 through the gap 47 even though the open / close door 23 does not open the prize winning port 22.
  Further, it is preferable that the predetermined width W in which the side end portion 23c of the open / close door 23 is inside the winning ball rolling area 22a of the big winning opening 22 is less than the radius of the game ball (for example, less than 5.5 mm). When the predetermined width W is larger than this, even if the open / close door 23 is in a state of closing the big winning opening 22, the side wall 45 of the winning ball rolling region 22a and the side end 23c of the open / close door 23 are not provided. There is a possibility that a game ball may be inserted between them, but by setting the predetermined width W to be less than the radius of the game ball, such a game ball can be prevented from being inserted.
