Description

  The present invention relates to a gaming machine represented by a ball game machine.

  A typical conventional gaming machine is provided with a variable winning device that takes an entry-permitted state that allows entry of a game ball and an entry-blocked state that blocks entry of a game ball. This is realized by changing the arrangement of the entry restricting member provided in the vicinity of the winning opening of the apparatus. As such a gaming machine, a flat-shaped entry restriction member is arranged in parallel to the game board and the winning opening is closed by the entry restriction member, and the entry restriction member is rotated from the entry prevention arrangement with respect to the horizontal rotation axis. In this structure, the upper end of the game is allowed to enter forward, and the game ball flowing down from above is received by the entry restricting member and guided to the winning opening, or the tongue piece extending in the front-rear direction and the tongue piece An entrance restricting arrangement in which an entrance restricting member having a front plate suspended from the front end of the game board is arranged at the back of the game board and the winning opening is closed by the front plate, and an entry permitting arrangement in which the opening and closing member is moved forward from the entry preventing arrangement. And a structure in which a game ball flowing down from above is received by an entry restricting member and guided or drawn into a winning opening (for example, see Patent Document 1).

  Here, operations of various devices of the game board 400 will be described. Prior to the description, various game states and transitions between game states will be described. The normal gaming state (normal gaming state) is a gaming state in which the jackpot winning probability related to the first special symbol and the second special symbol is low, and the variation display time of the first special symbol and the second special symbol is long ( Hereinafter, it is also referred to as “low probability non-short state”). The gaming state changes based on winning the jackpot. There are five types of jackpots related to the first special symbol: standard probability variation jackpots, sudden probability variation jackpots, latent probability variation jackpots, standard time minor jackpots and sudden time minor jackpots, and the types of jackpots related to the second special symbol are standard probability variation jackpots. There are two types per standard time junior college. If the standard probability change big hit or sudden probability change big win is won, the game state is temporarily a special game state where the big winning device 433 is intermittently allowed to enter (the open / close shutter 31 is intermittently allowed to enter). After the end of the special gaming state, the jackpot winning probability related to the first special symbol and the second special symbol is higher than the normal gaming state, and the variable display time of the first special symbol and the second special symbol is A transition is made to a gaming state shorter than the normal gaming state (hereinafter referred to as “high probability short-time state”). The high probability short-time state will be maintained until the next jackpot win. In addition, when winning the latent probability variation jackpot, after shifting to the special gaming state, the jackpot winning probability related to the first special symbol and the second special symbol is higher than the normal gaming state, the first special A transition is made to a gaming state (hereinafter referred to as a “high probability non-short state”) in which the variable display time of the symbol and the second special symbol is the same as the normal gaming state. The high probability non-short-time state is maintained until the next jackpot win. In addition, when winning the standard time jackpot, after the transition to the special gaming state, the jackpot winning probability related to the first special symbol and the second special symbol is the same low probability as the normal gaming state, the first special symbol Or the transition state to the gaming state (hereinafter referred to as “low probability short time state”) in which the display time of the variation of the second special symbol is the same as the normal gaming state. The low-probability short-time state is maintained until the end of the unit display control for a predetermined number of times (for example, 100 times) related to either the first special symbol or the second special symbol, but after that, the gaming state is changed to the normal gaming state. Return. In addition, when a big hit in the high probability short-time state and the high probability non-time-short state, compared to the big hit in the low-probability short-time state and the low-probability non-time-short state, either probability variation big hit (standard probability variation big hit, sudden probability variation big hit , The probability of distribution to the latent probability variation big hit) is large. In the following, operations of various devices of the game board 400 will be described in chronological order.

  In the main control board 920, winning random numbers relating to special symbols (common to the first special symbol and the second special symbol), symbol random numbers relating to special symbols (common to the first special symbol and the second special symbol), stop pattern random numbers, Various variation pattern random numbers are generated. When a game ball enters the first start winning device 431 in various game states, winning random numbers related to special symbols, symbol random numbers related to special symbols, and stop pattern random numbers are acquired. And stored in a predetermined area of the RAM of the main control board 920. At this time, when the special prize winning device 433 is not in operation, if both the first special symbol and the second special symbol are not in the variable display or the final display, immediately after the storage, the first special symbol and the second special symbol If any of the special symbols is in variable display or finalized display, the right of all jackpot lotteries related to the first special symbol acquired in advance and the number acquired in advance and subsequent 2. After all the jackpot lottery rights related to the special symbol are consumed, it is determined whether or not the jackpot is won based on the winning random number related to the acquired special symbol. In addition, as described above, the winning probability of jackpot related to the first special symbol is, depending on the current gaming state, in detail, it is a high probability state (high probability short time state, high probability non-short time state) or low probability state Specifically, the jackpot winning probability in the high probability state is higher than the jackpot winning probability in the low probability state. In the case of winning the jackpot, the stop symbol of the first special symbol is further determined based on the symbol random number related to the acquired special symbol. Depending on the type of the stop symbol, it is determined which of the big hits of standard probability variation big hit, sudden probability variation big hit, latent probability variation big hit, standard time short big hit and sudden time short big hit. Note that the distribution probability of various types of jackpots varies depending on the current gaming state, in particular, whether the state is a high probability state or a low probability state. The probability of distribution to big hit, sudden probability change big hit, and latent probability change big hit) is higher in the high probability state than in the low probability state. On the other hand, when winning a big hit and winning a small hit, a small hit symbol is set as a stop symbol, and when not winning a small hit, a lost symbol is set as a stop symbol. The

  After the jackpot lottery pertaining to the first special symbol, the current gaming state, the lottery result of the jackpot lottery, stop pattern random numbers, various variable pattern random numbers, the total reservation rights of the jackpot lottery pertaining to the first special symbol and the second special symbol The variation display time of the first special symbol is determined based on the number, and the variation pattern of the decorative symbol is selected. Thereafter, the variable display of the first special symbol on the first special symbol display device 471 and the variable display (variation effect) of the decorative symbol on the decorative symbol display device 479 are started. In the first special symbol, the variable display time spans. Thus, the variable display according to the fixed pattern is continued, and the decorative display is executed according to the variable pattern over the variable display time for the decorative design. As the variable display time elapses, the stop symbol is fixedly displayed as the first special symbol, and the symbol corresponding to the stop symbol of the first special symbol is fixedly displayed as the decorative symbol. The final display of the first special symbol and the decorative symbol is continued for a certain time.

  When the stop symbol of the first special symbol is a jackpot symbol, the gaming state shifts to the special gaming state after the final display of the first special symbol. In the special gaming state, the open / close shutter 31 of the big prize device 433 is intermittently moved to the entry allowable arrangement a predetermined number of times. After the opening / closing shutter 31 shifts to the entry permitting arrangement, the opening / closing shutter depending on whether a predetermined number (for example, 10) of game balls has entered the grand prize winning device 433 or a predetermined maximum opening time has elapsed. 31 moves to the entry blocking arrangement. After that, after the elapse of a predetermined closing time, the opening / closing shutter 31 again moves to the entry allowable arrangement. This opening / closing operation is repeated a predetermined number of times. The number of times the opening / closing operation of the opening / closing shutter 31 is repeated, the maximum opening time for staying in the allowable entry arrangement, and the like vary depending on the type of jackpot (the type of stop symbol). Specifically, in the special game state based on the standard probability variation big hit and the standard time short hit, the opening / closing operation in which the maximum opening time is 29.5 seconds and the closing time is 2.0 seconds is repeated only 16 times. In addition, after the waiting time (opening time) of 10.0 seconds from the start of the special gaming state, the transition of the opening / closing shutter 31 to the first entry allowable arrangement is started, and from the transition to the sixteenth entry prevention arrangement. After a waiting time (ending time) of 15.0 seconds, the special gaming state ends. On the other hand, in the special game state based on the sudden probability variation jackpot, the latent probability variation jackpot and the sudden time bonus jackpot, the opening / closing operation with a maximum opening time of 0.8 seconds and a closing time of 2.0 seconds is repeated only twice. In addition, after the standby time (opening time) of 3.2 seconds from the start of the special game state, the movement of the opening / closing shutter 31 to the first entry allowable arrangement is started, and from the movement to the second entry prevention posture. 3. After a waiting time (ending time) of 2 seconds, the special gaming state ends. After the end of the special gaming state, as described above, the game state is shifted according to the type of jackpot of this time.

  Further, when the stop symbol of the first special symbol is a small hit symbol or a lost symbol, the gaming state is not changed even after the final display of the first special symbol. However, when winning a small win, the big winning device 433 operates in the same manner as in the special gaming state based on the sudden probability change big hit, the latent probability change big hit, and the sudden time short hit.

  In the above description, the case where the right of jackpot lottery related to the first special symbol is digested has been described, but the type of jackpot lottery related to the second special symbol is also digested as described above. Except for the difference between the first special symbol and the second special symbol, and that the right of the jackpot lottery pertaining to the second special symbol is prioritized over the right of the jackpot lottery pertaining to the first special symbol, Since it is almost the same as the case of one special symbol, the first and second special symbols are replaced with the second special symbol and the first special symbol, respectively, and the redundant description is omitted.

  When a game ball enters the starting device 436 in various gaming states, a winning random number related to the normal symbol is acquired and stored in a predetermined area of a RAM (not shown) of the main control board 920. At this time, in the case where the second start winning device 432 is not in operation, immediately before the normal symbol is not in the variable display or the final display, or immediately before the normal symbol is in the variable display or the final display. After all the winning lottery rights have been acquired, it is determined whether or not the winning is based on the winning random number associated with the acquired normal symbol. Depending on the gaming state at the time of determination, the winning probability per win is either a short-time state (high probability short-time state, low-probability short-time state) or non-short-time state (low probability non-short state, high probability non-short state, It changes depending on whether it is a special gaming state), and the winning probability in winning in the short-time state is higher than in the non-short-time state. When winning a win, a predetermined winning symbol is set as a stop symbol, and when not winning, a predetermined lost symbol is set as a stopping symbol. After winning the lottery, normal symbol variation display is started, and in the non-short-time state, the variable display is continued in a certain pattern over a predetermined variation display time (for example, 3.0 seconds), and the short-time state is reached. In this case, the variable display with the same pattern as the normal gaming state is continued for a predetermined variable display time (for example, 0.5 seconds) shorter than the non-time-short state. As the predetermined time corresponding to the gaming state elapses, the stop symbol is fixedly displayed over a certain period of time as a normal symbol.

  When the stop symbol of the normal symbol is a winning symbol, the movable blade 452 of the second start winning device 432 shifts to the approach allowable posture at least once after the normal symbol is confirmed and displayed. Specifically, in the case of winning in a non-time-short state, the movable blade 452 typically enters a predetermined maximum opening time (for example, 0.2 seconds) a predetermined number of times (for example, one time). In the case of winning in the short-time state, the movable blade 452 typically has a predetermined maximum opening time that is longer than the non-short-time state by a predetermined number of times (eg, three times) more than the non-short-time state. For example, it shifts to the approach allowable posture for 1.9 seconds. However, when a predetermined number (for example, 10) of game balls enter the second start winning device 432, the movable blade 452 forcibly shifts to the entry blocking state, and is movable based on the winning of this time. The operation of the blade 452 ends.

As the plunger 33 moves, the first power transmission member 35 also moves rearward, the pressed portion 36B is pressed rearward by the pressing portion 35C, and the second power transmission member 36 is counterclockwise about the support shaft 36A. Rotate around. With the rotation of the second power transmission member 36, the rear wall forming the outline of the through hole 31A is pressed rearward by the pressing portion 36C, and the open / close shutter 31 moves rearward.

  On the contrary, if the exciting coil 32 is demagnetized in the case where the big winning device 433 is in the permissible entry state shown in FIGS. 20 (B), 21 (B) and 22 (B), the first power transmission member 35 moves forward by the urging force from the urging member 34. As the first power transmission member moves, the plunger 33 also moves rearward, the pressed portion 36B is pressed forward by the pressing portion 35C, and the second power transmission member 36 is centered on the support shaft 36A. Rotate around. With the rotation of the second power transmission member 36, the wall on the front side that forms the outline of the through hole 31A is pressed forward by the pressing portion 36C, and the open / close shutter 31 moves forward.

  Here, a case where an external force is applied to the opening / closing shutter 31 in the entry blocking state of the big winning device 433 is applied from the entry prohibition arrangement to the entry allowance arrangement. FIG. 23 is a cross-sectional view of the big prize device 433 showing a case where an external force is applied to the opening / closing shutter 31. FIG. 23 (A) shows a case where a weak external force is applied, and FIG. The case where a strong external force is applied to the shutter 31 is shown.

  When the big prize winning device 433 is in the entry blocking state shown in FIGS. 20A, 21A and 22A, the opening / closing shutter 31 is made to move from the entry prohibition arrangement to the entry permission arrangement. When an external force is applied, the opening / closing shutter 31 moves rearward, the pressing portion 35C is pressed rearward by the front wall forming the outline of the through hole 31A, and the second power transmission member 36 is supported by the support shaft 36A. Rotate counterclockwise around the center. As the second power transmission member 36 rotates, the pressed portion 36B comes into contact with the pressing portion 35C as shown in FIG. 23A, but the force by which the pressed portion 36B presses the pressing portion 35C is the pressing portion. It is not converted into a force that moves 35C to the rear side, and the first power transmission member 35 does not move to the rear side. In the state shown in FIG. 23A (locked state), the game ball is not allowed to enter the receiving portion 10 through the opening 10A.

  When the external force is weak with the opening / closing shutter 31, the state shown in FIG. 23A is maintained. When the external force is strong, as shown in FIG. 23B, the support shaft 36A is maintained. The connecting portion 36D that connects the pressing portion 36C is bent, and the opening / closing shutter 31 moves further to the rear side. In the state shown in FIG. 23B, the entry of the game ball into the receiving portion 10 through the opening 10A is not blocked. Even if the tip of the opening / closing shutter 31 is moved to a position where it does not protrude forward from the through hole 11A as shown in FIG. 23B, the connecting portion 36D is irreversibly deformed or broken. In other words, the material, shape, and the like of the connection portion 36D are selected so as to be deformed within the range of plastic deformation of the connection portion 36D.

  Here, a case where the game ball contacts the front end of the opening / closing shutter 31 in the process in which the opening / closing shutter 31 moves from the entry allowable arrangement to the entry blocking arrangement will be described. 24 and 25 are cross-sectional views showing a part of the vicinity of the open / close shutter 31 in the prize winning device 433 in order to explain the posture of the open / close shutter 31, and FIG. 24 shows the open / close shutter 31 in the standard posture. FIGS. 25A and 25B respectively show the case where the open / close shutter 31 is in the left rotation posture and the right rotation posture displaced from the standard posture. In FIGS. 25A and 25B, the open / close shutter 31 in the standard posture is shown by a broken line for comparison.

  As shown in FIG. 24, the opening / closing shutter 31 has a through hole 31A having a size larger than the size of the pressing portion 36C. As shown in FIG. 25B, a predetermined range of displacement (up to about 2 degrees of rotation) is possible with respect to the case shown in FIG. When moving from the entry allowable arrangement to the entry prevention arrangement or when moving from the entry allowable arrangement to the entry prevention arrangement, if the game ball is not in contact with the front end of the open / close shutter 31, as shown in FIG. The left and right ends of the part 36C take a standard posture in which they are in contact with one of the wall forming the front end of the through hole 31A and the wall forming the rear end of the through hole 31A. 25A, as shown in FIG. 25A, the right end portion of the pressing portion 36C is in contact with the wall forming the front end of the through hole 31A, but the left end portion of the pressing portion 36C is the through hole. As shown in FIG. 25 (B), the left rotation posture that is in contact with the wall that forms the rear end of 31A and the right end of the pressing portion 36C are in contact with the wall that forms the rear end of the through hole 31A. However, the left end of the pressing portion 36C is the through hole 31. Clockwise orientation walls forming the front and in contact can take.

  Specifically, when the front end of the opening / closing shutter 31 is in contact with the game ball and the contact point is in the central region (Q1 to Q2), the standard posture is taken as shown in FIG. When the contact point is the right region (Q2 to right end) of the front end, the left rotation posture is taken as shown in FIG. 25A, and the contact point of the open / close shutter 31 with the game ball is the left region (left end of the front end). ˜Q1), the left rotation posture is taken as shown in FIG.

  As shown in FIGS. 24 and 25, the outline of the front end of the open / close shutter 31 is formed by a straight region (P1 to P2) and a curved region (P2 to P3) smoothly connected to the straight region. When the opening / closing shutter 31 is in the standard posture with the distance between an arbitrary part on the contour and the part of the front cover plate 13 facing the part as the opposing distance, as shown in FIG. The facing distance corresponding to the part in the straight region is the same over the entire straight line region, and the facing distance corresponding to the part in the curved region decreases monotonously as it shifts to the right. Further, when the open / close shutter 31 is in the right rotation posture, as shown in FIG. 25A, it corresponds to the region from the left end (P1) to the middle (P4) of the entire region (P1 to P3). The facing distance corresponding to the part from the middle (P4) to the right end (P3) of the entire region is monotonously shortened as it shifts to the right. Further, when the open / close shutter 31 is in the left rotation posture, as shown in FIG. 25B, the facing distance to the front cover plate 13 corresponding to the portion in the entire region is monotonously shortened.

  Here, a description will be given of a case where the open / close shutter 31 and the front cover plate 13 come into contact with the game ball so as to sandwich the single game ball in the process in which the open / close shutter 31 moves from the entry allowance arrangement to the entry prevention arrangement. FIG. 26 is a cross-sectional view illustrating a state in which the open / close shutter 31 and the front cover plate 13 are in contact with a single game ball. 27, 28 and 29 are top views showing a state where the opening / closing shutter 31 and the front cover plate 13 are in contact with a single game ball. FIG. 27 shows the opening / closing shutter 31 and the front surface. The case where the cover plate 13 and the contact position are in the central area (Q1 to Q2) is shown, and FIG. 28 shows the case where the contact position of the open / close shutter 31 and the game ball is in the right end area (Q2 to right end). FIG. 29 shows the case where the contact position between the open / close shutter 31 and the game ball is within the left end region (left end to Q1).

  When the opening / closing shutter 31 and the front cover plate 13 come into contact with the game ball so as to sandwich a single game ball, the contact point between the opening / closing shutter 31 and the game ball is the center as shown in FIG. Regardless of whether it is in the region, the right region or the left region, the game ball comes into contact with the tip of the opening / closing shutter 31 and the tip of the protrusion 13A formed on the front cover plate 13. .

  First, when the contact point between the open / close shutter 31 and the game ball is in the central region (Q1 to Q2), the open / close shutter 31 takes a standard posture as shown in FIGS. A region (P2) that monotonously shortens as the opposing distance between the front cover plate 13 and the open / close shutter 31 shifts to the right in the standard posture when the game ball and the open / close shutter 31 are in contact with the plate 13 at the contact point Rc in the protrusion 13A. To contact at a contact point Sc within a range of P3). Therefore, even if the movement of the game ball is momentarily stopped in this state, the center of gravity of the game ball is in a plane πc including a straight line Lc (not shown) passing through the contact point Rc and the contact point Sc and a straight line in the vertical direction. Since the (center) is not included, the force that rotates the game ball by a rotational moment about the straight line Lc based on the weight of the game ball and the force that moves the game ball to the left side by the pressing force from the open / close shutter 31 Will be granted. Further, since the protruding portion 13A and the opening / closing shutter 31 are inclined, a force for moving the game ball to the left side is applied based on the weight of the game ball.

  Next, when the contact point between the open / close shutter 31 and the game ball is in the right region (Q2 to the right end side), as shown in FIG. 28, the open / close shutter 31 takes the left rotation posture, and the game ball and the front cover are covered. A region that monotonously shortens as the opposing distance between the front cover plate 13 and the open / close shutter 31 shifts to the right in a counterclockwise posture when the game ball and the open / close shutter 31 are in the counterclockwise contact position Rr in the protruding portion 13A. Contact is made at the contact point Sr within the range of P4 to P3). Therefore, even if the movement of the game ball is momentarily stopped in this state, the center of gravity of the game ball is on a plane πr including a straight line Lr (not shown) passing through the contact point Rr and the contact point Sr and a straight line in the vertical direction. Since (center) is not included, a force that rotates the game ball by a rotational moment about the straight line Lr based on the weight of the game ball and a force that moves the game ball to the left by the pressing force from the opening / closing shutter 31 In addition, since the protruding portion 13A and the opening / closing shutter 31 are inclined, a force for moving the game ball to the left side is applied based on the weight of the game ball.

  Finally, when the contact point between the open / close shutter 31 and the game ball is in the left region (left end side to Q1), as shown in FIG. 29, the open / close shutter 31 takes the right rotation posture, and the game ball and the front cover are covered. A region that monotonously shortens as the opposing distance between the front cover plate 13 and the opening / closing shutter 31 shifts to the right side when the board 13 contacts the contact point Rl at the protruding portion 13A and the game ball and the opening / closing shutter 31 rotate to the right. Contact is made at the contact point Sl within the range of P4 to P3). Therefore, even if the movement of the game ball is momentarily stopped in this state, the center of gravity of the game ball is on a plane πl including a straight line Ll (not shown) passing through the contact point Rl and the contact point S1 and a straight line in the vertical direction. Since (center) is not included, the force to rotate the game ball by a rotational moment about the straight line L1 based on the weight of the game ball and the force to move the game ball to the left side by the pressing force from the opening / closing shutter 31 In addition, since the protruding portion 13A and the opening / closing shutter 31 are inclined, a force for moving the game ball to the left side is applied based on the weight of the game ball.

  In the case of the gaming machine 100 described above, it is assumed that the opening / closing shutter 31 and the front cover plate 13 are in contact with the game ball so as to sandwich the game ball in the process of moving the opening / closing shutter 31 from the entry allowance arrangement to the entry prevention arrangement. In addition, regardless of the contact position between the opening / closing shutter 31 and the game ball, the front cover plate 13 and the opening / closing shutter 31 are rotated to the side (left side) where the facing distance is longer than the facing distance corresponding to the contact position. Since the moving force is applied, it is possible to prevent the game ball from being continuously held by the opening / closing shutter 31 and the front cover plate 13.

  In the case of the gaming machine 100 described above, since the opening / closing shutter 31 and the protruding portion 13A of the front cover plate 13 are provided to be inclined, regardless of the contact position between the opening / closing shutter 31 and the game ball. Since a force for moving the front cover plate 13 and the opening / closing shutter 31 to the side (left side) where the facing distance is longer than the facing distance corresponding to the contact position is easily applied, the game ball moves between the opening / closing shutter 31 and the front surface. It can suppress more favorably that it is continuously hold | maintained with the coating | coated board 13. FIG.

  Further, in the case of the gaming machine 100 described above, when the contact point between the opening / closing shutter 31 and the game ball is the central region (Q1 to Q2), the game ball is connected to the opening / closing shutter 31 and the protruding portion 13A of the front cover plate 13. Since the opening / closing shutter 31 changes from the standard posture to the right rotation posture if it advances to the boundary (Q1) with the center region and the left region in contact with the ball, the left side (game ball traveling direction side) from the boundary. The facing distance corresponding to the part increases rapidly, and the game ball can enter the opening 10A very well. Similarly, when the contact point between the open / close shutter 31 and the game ball is in the right region (Q2 to the right end), the game ball is in contact with the open / close shutter 31 and the protruding portion 13A of the front cover plate 13 in the center. Since the opening / closing shutter 31 changes from the left rotation posture to the standard posture when the region, the right region, and the boundary (Q2) travel, the facing distance corresponding to the portion on the left side (game ball traveling direction side) from the boundary is It becomes large rapidly, and the game ball can enter the opening 10A very well. When the contact point between the open / close shutter 31 and the game ball is the left region (left end side to Q1), the left region and the inclined portion 13A of the front cover plate 13 are inclined as compared with the other regions. Since the angle is set to be large, the game ball can rapidly enter the opening 10A. Therefore, in the gaming machine 100, even if the opening / closing shutter 31 interferes with the game ball, the opening / closing shutter 31 moves favorably from the entry permitting arrangement to the entry blocking arrangement. In the above description, the case where the game ball enters the opening 10A has been described. However, depending on the contact position between the opening / closing shutter 31 and the protrusion 13A of the front cover plate 13 in the game ball, Thus, the upper surface of the opening / closing shutter 31 is moved.

  In the case of the gaming machine 100 described above, the facing distance corresponding to the upstream side (right side) of the slope with respect to the contact position between the open / close shutter 31 and the game ball is shorter than the facing distance corresponding to the contact position. When the ball is moving in a state of being sandwiched on the downstream side of the inclination, it is possible to prevent the game ball from being newly sandwiched on the upstream side of the position of the game ball. That is, since it is possible to prevent the game balls from being sandwiched continuously, the time required for the opening / closing shutter 31 to move to the entry blocking arrangement can be reduced.

  Further, in the case of the above gaming machine 100, a gap is formed between the opening / closing shutter 31 and the protruding portion 13A of the front covering plate 13, but the upper end of the front covering plate 13 is located from the position facing the opening / closing shutter 31. Since it extends to the upper side, it is difficult to recognize the existence of the gap.

  In the case of the gaming machine 100 described above, the upper end of the front cover plate 13 is in the vicinity of the position facing the opening / closing shutter 31 and on the upper side of the position, the protruding portion is substantially parallel to the entire width of the opening / closing shutter 31. Since 13A is provided, the presence of a gap formed between the open / close shutter 31 and the protruding portion 13A of the front cover plate 13 can be more difficult to recognize by the uneven shape and thickness of the protruding portion 13A.

  Further, in the case of the gaming machine 100 described above, an unauthorized tool is inserted from a gap formed between the opening / closing shutter 31 and the protruding portion 13A of the front cover plate 13 so that the opening / closing shutter 31 is illegally allowed to enter. Even if an external force is applied, the locked state shown in FIG. 23A is obtained, so that it is possible to suppress the opening / closing shutter 31 from being moved to the allowable entry position.

  Further, in the case of the above gaming machine 100, although it is difficult depending on unauthorized tools, the front block 102 is opened in the gap formed between the opening / closing shutter 31 and the protruding portion 13A of the front cover plate 13. By inserting the finger, the open / close shutter 31 can be moved to the entry-permitted arrangement, so that a player's loss can be easily compensated when a malfunction occurs in the gaming machine.

  In the gaming machine 100 described above, a configuration has been described in which the opening / closing shutter 31 has a different posture depending on the contact point between the opening / closing shutter 31 and the game ball. However, in the present invention, the contact point between the opening / closing shutter 31 and the game ball. As can be easily understood from the description in the case of the central region, the open / close shutter may not have a different posture unless the open / close shutter has a linear portion parallel to the protruding portion 13A of the front cover plate 13, Even if it is this structure, there exists an effect that it can suppress that a game ball is continuously hold | maintained by the opening-and-closing shutter and the front surface cover board 13. FIG. On the contrary, as can be easily understood from the description in the case where the contact point between the open / close shutter 31 and the game ball is the left side region, the open / close shutter can be protruded from the front cover plate 13 if the posture of the open / close shutter can be appropriately changed. A configuration having a linear portion parallel to 13 </ b> A may be used, and even with this configuration, it is possible to prevent the game ball from being continuously held by the opening / closing shutter 31 and the front cover plate 13. Further, like the gaming machine 100, the posture of the opening / closing shutter 31 can be appropriately changed, and the opening / closing shutter 31 has a linear shape portion parallel to the protruding portion 13A of the front cover plate 13. The maximum facing distance in the gap formed between the open / close shutter 31 and the protruding portion 13A of the front cover plate 13 can be reduced, and an unnecessarily large gap can be prevented from being formed.

  In the gaming machine 100 described above, the case where the shape of the front end of the opening / closing shutter 31 is constituted by the straight region (P1 to P2) and the curved region (P2 to P3) has been described. A configuration in which the shape of the front end is formed only by a curved region or a configuration formed only by a linear shape that is not parallel to the protruding portion 13A of the front cover plate 13 may be employed. If the angle or the like is appropriately designed, there is an effect that it is possible to suppress the game ball from being continuously held by the opening / closing shutter 31 and the front cover plate 13.

  In the gaming machine 100 described above, the configuration in which the opening / closing shutter 31 moves back and forth has been described. However, the opening / closing shutter 31 may be configured to move only by rotational movement or by a combined movement of rotational movement and forward / backward movement. When employed, the front end shape of the opening / closing shutter may be a linear shape that is parallel to the protruding portion 13A of the front cover plate 13 in either the entry blocking arrangement or the entry allowing arrangement of the opening / closing shutter.

  In the gaming machine 100 described above, the configuration in which the protruding portion 13A of the front cover plate 13 has a linear shape has been described. However, in the present invention, the front cover plate 13 and the protruding portion 13A are the same as the open / close shutter 31 and its variations. The front end of the open / close shutter 31 may have a linear shape, and even with these configurations, the game ball can be prevented from being continuously held by the open / close shutter 31 and the front cover plate 13. There is an effect. When the front cover plate 13 and the protrusion 13A are non-linear, the unevenness of the front cover plate 13 and the protrusion 13A causes the game ball to enter the opening 10A even if the open / close shutter 31 is allowed to enter. Since smooth entry may be hindered, a configuration in which the protruding portion 13A of the front cover plate 13 has a linear shape is preferable as in the gaming machine 100.

[Invention group extracted from each of the above embodiments]
The features of the invention group extracted from the above embodiment will be described while showing effects and the like as necessary. In the following, in order to facilitate understanding, the correspondence with the configuration in the above-described embodiment is appropriately shown in parentheses, but is not limited to the configuration in parentheses.

  As described above, in a conventional typical gaming machine, a variable winning device (corresponding to the big winning device 433) that takes an entry permitting state that allows entry of a game ball and an entry blocking state that prevents entry of a game ball. The change in the permissible state is realized by a change in the arrangement of the entry restricting member provided in the vicinity of the winning opening of the variable winning device. As such a gaming machine, a flat-shaped entry restriction member is arranged in parallel to the game board and the winning opening is closed by the entry restriction member, and the entry restriction member is rotated from the entry prevention arrangement with respect to the horizontal rotation axis. In this structure, the upper end of the game is allowed to enter forward, and the game ball flowing down from above is received by the entry restricting member and guided to the winning opening, or the tongue piece extending in the front-rear direction and the tongue piece An entrance restricting arrangement in which an entrance restricting member having a front plate suspended from the front end of the game board is arranged at the back of the game board and the winning opening is closed by the front plate, and an entry permitting arrangement in which the opening and closing member is moved forward from the entry preventing arrangement. And a structure in which a game ball flowing down from above is received by an entry restricting member and guided or drawn into a winning opening (for example, see Patent Document 1). In a typical conventional gaming machine, when trying to move the entry restricting member from the entry permitting arrangement to the entry preventing arrangement, the game ball is pinched by the entry restricting member and other peripheral members, and the entry preventing arrangement is provided. The situation that cannot complete the move to.

  The following invention A group can be extracted from the viewpoint of favorably moving the entry restricting member from the entry permitting arrangement to the entry preventing arrangement when the state of the entry restricting member (opening / closing shutter 31) is changed in the variable prize winning device (large winning device 433). In addition, even if a gap is formed between the entry restricting member and the receiving part in order to move the entry restricting member favorably from the entry permitting arrangement to the entry preventing arrangement when the state of the entry restricting member changes in the variable prize device. From the viewpoint of making it difficult to induce cheating or suppressing cheating, the following invention group B can be extracted.
