JP 2008-307315 A JP 2012-010740 A

  In the above-described prior art, when the open / close door is in a closed state, the surface facing the board surface of the game board unit and the open / close door are very close to each other, so that dust such as dust and dust tends to accumulate on the open / close door. It was. In Patent Document 2, since it is an M-shaped opening / closing door, dust does not collect in the concave portion, but dust tends to collect in the left and right portions of the concave portion very close to the surface facing the board surface of the game board unit. It was. Here, when the open door changes from the open state to the closed state, a phenomenon in which the game ball is sandwiched between the surface facing the game board surface and the open / close door and stays for a while, so-called ball biting may occur. Therefore, in the structure of the prior art described above, when ball biting occurs, dust tends to accumulate, so that the surface is difficult to slip, and it is difficult to escape from the pinched state. That is, the ball biting is likely to occur, which may frustrate the player, and it has not been possible to suppress a decrease in interest in the game.

  Accordingly, an object of the present invention is to provide a technique that suppresses the occurrence of ball biting and suppresses a decrease in interest in games by providing a gap over the entire opening width of the special winning opening.

The present invention employs the following means for solving the above problems.
Solution 1: A gaming machine according to the present solution includes a entrance opening formed in a predetermined area on the game board surface, a front cover that defines a size of the entrance opening and is opposed to the game board surface. A closed position that makes it difficult or impossible to enter a game ball into the entrance in a state of projecting toward the back side of the front cover plate in a direction perpendicular to the game board surface, and the closed position An opening / closing member that is displaced between an open position that facilitates entry of a game ball into the entrance in a state of being retracted from the protruding state to the game board surface side, and when a predetermined operating condition is satisfied, An opening / closing driving means for operating the opening / closing member between the closed position and the open position; and when the opening / closing member is displaced to the closed position by the operation of the opening / closing driving means, the opening / closing member and the front cover plate are And a separation means for separating. It is a game machine to be.

  According to this solution, when winning a lottery for a special symbol or a normal symbol, a variable winning device or a variable starting winning device is activated, but the winning opening formed by these variable winning device or variable starting winning device is It is opened or closed by an opening / closing member. Further, when the opening / closing member is in the closed position, a gap is provided between the opening / closing member and the front cover plate provided to face the opening / closing member. This gap is provided by limiting the range in which the opening / closing member can be displaced. Specifically, the gap is provided by setting the position where the opening / closing member is displaced to the closed position to a position where it does not contact the front cover plate.

  In this way, by providing a gap, it is difficult for dust and other debris to accumulate around the winning prize opening, and the slipperiness (surface roughness, coefficient of friction) of the surface of the opening / closing member and front cover plate is reduced. Can keep. Therefore, even if a game ball is caught between the opening / closing member and the front cover plate or a ball bit is generated, the ball bite can be eliminated immediately without causing a stagnation in the place. Thereby, a player does not become frustrated and the fall of the interest with respect to a game can be suppressed.

  Solution 2: The gaming machine of the present solution is a standing plate provided on the back surface of the front cover plate in a state of facing the opening / closing member and projecting toward the game board surface along the entrance. The separation means separates the opening / closing member and the standing plate when the opening / closing member is displaced to the closed position by the operation of the opening / closing driving means. .

  According to this solution, the standing plate is provided on the front cover plate along the winning opening so as to face the opening / closing member. Further, when the opening / closing member is in the closed position, a gap is provided between the opening / closing member and the standing plate provided to face the opening / closing member. This gap is provided by limiting the range in which the opening / closing member can be displaced. Specifically, the gap is provided by setting the position where the opening / closing member is displaced to the closed position to a position where the opening / closing member does not contact the standing plate.

  In this way, by providing a gap, it is difficult for dust and other debris to accumulate around the winning prize opening, and the slipperiness (surface roughness, coefficient of friction) of the surface of the opening / closing member and front cover plate is reduced. Can keep. Therefore, even if a game ball is caught between the opening / closing member and the standing plate or a ball bit is generated, the ball bite can be eliminated immediately without stagnation on the spot.

  Further, if the ball bite occurs, the game ball comes into contact with the standing plate instead of the front cover plate. Here, when only the front cover plate is provided without a standing plate, the relationship between the front cover plate and the opening / closing member can be replaced with the relationship between the surface and the line, and the number of places where the game ball contacts increases. Come. On the other hand, when the standing plate is provided, the relationship between the standing plate and the opening / closing member can be replaced with the relationship between the lines, and the number of places where the game ball contacts is smaller than the relationship with the surface. Therefore, the phenomenon that a game ball is pinched, such as a ball bite, indicates that the relationship between the line and the line is less likely to occur than the relationship between the surface and the line because there are fewer places where the game ball contacts the game ball. In addition, the occurrence of the ball biting can be suppressed by providing the standing plate. In addition, it is clear that the ball biting occurs and the state is maintained, i.e., the game ball is stagnant because of the relationship between the surface and the line. Can be resolved immediately.

  In this way, even if a game ball is caught between the opening and closing member and the standing plate or a ball bit occurs, the ball bit can be resolved immediately without stagnation on the spot, and the player may be frustrated. It is possible to suppress a decrease in interest in games.

  Solution 3: The gaming machine of the present solution is the solution 1 or 2 in which at least one of the surface of the standing plate facing the opening / closing member or the surface of the opening / closing member facing the standing plate. The surface is a gaming machine characterized in that it includes an inclined surface that is inclined downward toward the outside of the entrance.

  In the present solution, the front end portions of the standing plate and the opening / closing member are each or at least one of them is a slope whose surface faces downward. That is, the opposing surface is not a flat surface. Therefore, even if a game ball is caught between the opening and closing member and the standing plate or a ball bite occurs, the contact surface that comes into contact with the game ball is small, so that the ball bite is immediately stopped without stagnation on the spot. Can be resolved.

  Solution 4: A gaming machine according to the present solution is provided in any one of solutions 1 to 3, wherein a surface of the standing plate facing the opening / closing member or a surface of the opening / closing member facing the standing plate. At least one of the surfaces includes a plurality of inclined surfaces having different degrees of inclination.

  In the present solution, a plurality of inclined surfaces of the standing plate and the tip of the opening / closing member are provided. For example, it is composed of two inclined surfaces with different inclination angles. Therefore, even if a game ball is caught between the opening and closing member and the standing plate or a ball bite occurs, the contact surface that comes into contact with the game ball is small, so that the ball bite is immediately stopped without stagnation on the spot. Can be resolved.

  Solution 5: The gaming machine of the present solution is the solution of any one of solutions 1 to 4, wherein the surface of the upright plate that faces the opening / closing member is inclined in order toward the direction in which the game ball falls. A plurality of inclined surfaces including at least a surface and a second inclined surface, wherein the first inclined surface is inclined by a predetermined first inclination degree in a direction toward the front cover plate while being directed in a direction in which the game ball falls. The second inclined surface is inclined in the direction in which the game ball falls, and is inclined by a second inclination degree that is higher in the degree toward the front cover plate than in the first inclination degree. It is a gaming machine to play.

  In this solving means, the surface of the tip portion of the standing plate is composed of a first inclined surface having a gentle inclination angle and a second inclined surface having a large inclination angle. Thus, by having two steps of inclination angles, the strength of the standing plate can be increased, and even if the game ball collides, the standing plate can be prevented from being lost. Further, even if a game ball is caught between the opening and closing member and the standing plate or a ball bit is generated, the contact surface that comes into contact with the game ball is limited to the first inclined surface, and the contact surface is reduced. It is possible to eliminate the ball biting without stopping at the spot.

  Solution 6: The gaming machine according to the present solution may be configured such that, in any one of Solution 1 to 5, the surface of the standing plate facing the opening / closing member is coated with a lubricant on the first inclined surface. A gaming machine characterized by including a coating surface that can be formed.

  In this solution, a lubricant (lubricating oil) can be applied to the first inclined surface at the tip of the standing plate. Therefore, even if a game ball is caught between the opening and closing member and the standing plate or a ball bit occurs, the contact surface that comes into contact with the game ball is the first inclined surface, and the first inclined surface slides. Since it can be made easy, it is possible to immediately eliminate the biting of the ball without stagnation on the spot.

  Solution 7: The gaming machine according to this solution is the gaming machine according to any one of solutions 1 to 6, wherein a surface of the opening / closing member facing the standing plate faces in a direction in which the game ball falls. In order, it comprises a plurality of inclined surfaces including at least a third inclined surface and a fourth inclined surface, the third inclined surface is parallel to the front cover plate, and the game ball falls on the fourth inclined surface. The gaming machine is characterized by being inclined by a predetermined fourth inclination degree in a direction toward the game board surface while being directed in a direction toward the player.

  In the present solution, the opening / closing member includes a third inclined surface having a non-inclined surface and a fourth inclined surface having a large inclination angle. By having the two-step inclination angle in this way, even if the game ball is caught between the opening / closing member and the standing plate or the ball bite occurs, the contact surface that comes into contact with the game ball is the third inclination. It is limited to only the surface, the contact surface can be reduced, and the ball bite can be eliminated immediately without stagnation on the spot.

  Solving means 8: The gaming machine of the present solving means is the gaming machine according to any one of the solving means 1 to 7, wherein when a lottery opportunity occurs during the game, a lottery executing means for executing a predetermined lottery, and the lottery When executed, it further comprises symbol display means for displaying the symbols in a manner corresponding to the result of the lottery after the symbols are variably displayed over a predetermined variation time, and the opening / closing drive means includes the symbol display means When the symbol is stopped and displayed in the winning mode, the opening / closing member is operated between the closed position and the open position, assuming that the predetermined operating condition is satisfied.

  In this way, when the internal lottery regarding the special symbol and the operation lottery regarding the normal symbol are executed, the result of those lotteries corresponds to the winning, and when the special symbol or the normal symbol is stopped in the winning mode, the solenoid Is driven, and the opening / closing member connected to the solenoid is displaced to open the winning opening.

  According to the gaming machine of the present invention, by providing a gap over the entire opening width of the special winning opening, it is possible to suppress the occurrence of ball biting and to suppress a decrease in interest in the game.

The game balls that have passed through the start gate 20 continue to flow down in the game area 8a, but the upper start winning port 26, the normal winning ports 22, 24, the variable start winning device 28, the first variable winning device 30, and the second variable winning game. The game balls that have entered the device 31 are collected to the back side of the game board unit 8 through through holes formed in the game board (plywood material, transparent board, etc. constituting the game board unit 8).

  Here, in the present embodiment, due to the configuration of the game area 8a (board surface), when a game ball is to be entered in the normal winning opening 24 or the second variable prize winning device 31, the right side area (right-handed) in the game area 8a. It is necessary to hit a game ball in the area (perform a so-called “right strike”).

  In the present embodiment, the variable start winning device 28 operates when a predetermined operating condition is satisfied (when a normal symbol is stopped and displayed for a predetermined stop display time in a winning manner), and accordingly. It is possible to enter the lower start winning opening 28a (ordinary electric accessory). The variable start winning device 28 has, for example, a pair of left and right opening / closing members 28b, and these opening / closing members 28b reciprocate in the left-right direction along the board surface by the action of a link mechanism using a solenoid (not shown), for example. That is, as shown by the solid line in FIG. 3, the left and right opening / closing members 28b are in the closed position with their tips facing upward, and at this time, it is impossible to enter the lower start winning opening 28a (the game ball is (There is no gap to enter). On the other hand, when the variable start winning device 28 is operated, the left and right open / close members 28b are displaced (expanded) from the closed position toward the open position, and the opening width is expanded to the left and right to open the lower start winning opening 28a. During this time, the variable start winning device 28 is in a state in which it is possible to enter a game ball, and can enter the lower start winning opening 28a (variable start winning means). At this time, the opening / closing member 28b also functions as a member for guiding the entry of the game ball into the start winning opening 28a. Further, the arrangement of the obstacle nails installed in the game board unit 8 is basically an aspect that does not extremely impede the flow of the game ball toward the variable start winning device 28 (the lower start winning port 28a at the time of opening). However, the game ball does not necessarily enter the variable start winning device 28 (lower start winning port 28a) at the time of the opening operation, and the balls are generated randomly.

  The first variable winning device 30 operates when a specific operating condition is satisfied (when the special symbol is stopped and displayed in a mode other than non-winning), and enters the big winning opening (no reference sign). Enable the ball (first special electric accessory, special winning event generating means). The first variable winning device 30 has, for example, one opening / closing member 30a. The opening / closing member 30a reciprocates in the front-rear direction with respect to the board surface by the action of a link mechanism using a solenoid (not shown), for example. As shown in the drawing, the opening / closing member 30a is in the closed position (closed state) along the board surface, and at this time, it is impossible to enter the big prize opening (the first big prize opening is closed). When the first variable winning device 30 is operated, the opening / closing member 30a is displaced so as to fall forward with its lower end edge portion as a hinge, thereby opening the large winning opening (open state). During this time, the first variable prize-winning device 30 is in a state where it is not impossible to enter a game ball, and an event of entering a big prize opening can be generated. At this time, the opening / closing member 30a also functions as a member that guides the entry of the game ball into the big prize opening. Here, similarly, the arrangement of the obstacle nails installed in the game board unit 8 basically does not extremely impede the flow of the game ball toward the first variable prize winning device 30 (the big prize opening during operation). However, the game ball does not necessarily enter the first variable prize-winning device 30 at the time of operation, and the ball is generated randomly.

  Similar to the first variable winning device 30, the second variable winning device 31 operates when a specified condition is satisfied (when the special symbol is stopped and displayed in a mode other than non-winning), It is possible to enter the ball (without the reference sign) (second special electric accessory, special winning event generating means). The second variable winning device 31 is a device arranged at the lower right of the effect unit 40 (so-called right attacker), and has, for example, one opening / closing member 31a. The first variable winning device 30 employs a device in which the opening / closing member 30a is tilted forward. The second variable winning device 31 is a device in which the opening / closing member 30a is slid into the board surface. Adopted (slide type attacker). The opening / closing member 31a reciprocates in the front-rear direction with respect to the board surface by, for example, a link mechanism using a solenoid (not shown). The opening / closing member 31a is in the closed position (closed state) in a state of protruding from the board surface to the player side. At this time, the game ball rolls on the upper surface of the opening / closing member 31a. Is impossible (the second big prize opening is closed). When the second variable winning device 31 is activated, the opening / closing member 31a is drawn into the inside of the board surface to open the special winning opening (open state). During this time, the second variable winning device 31 is in a state where the inflow of the game ball is not impossible, and can generate an event of entering the big winning opening.

  In addition, an out port 32 is formed in the game area 8a, and the game balls that have not entered the winning ports are finally collected through the out port 32 to the back side of the game board unit 8. In addition, the game balls including the game balls that have entered the normal winning ports 22, 24, the variable start winning device 28 (lower start winning port 28a), and the first variable winning device 30 (large winning port) are driven into the game area 8a. All the game balls are collected to the back side of the game board unit 8. The collected game balls are discharged out of the frame from the back side of the pachinko machine 1 through an out passage assembly (not shown), and further join a supply path of an island facility (not shown).

FIG. 4 is an enlarged front view showing a part of the game board unit 8 (lower right position in the window 4a).
The game board unit 8 is provided with a normal symbol display device 33 and a normal symbol operation memory lamp 33a, for example, at the lower right position in the window 4a, as well as a first special symbol display device 34 and a second special symbol display device 35. A first special symbol operation memory lamp 34a, a second special symbol operation memory lamp 35a, and a game state display device 38 are provided.

  Among these, the normal symbol display device 33, for example, turns on two lamps (LEDs) alternately to display the normal symbols variably, and stops and displays the normal symbols when the lamps are turned on or off. The normal symbol operation memory lamp 33a displays 0 to 4 memory numbers depending on, for example, a combination of turning off, lighting, or blinking of two lamps (LEDs). For example, in a display mode in which both lamps are extinguished, a memory number of 0 is displayed, in a display mode in which one lamp is lit, a memory number of 1 is displayed, and in a display mode in which the same one lamp is blinked. In the display mode in which two stored numbers are displayed, and in addition to blinking one lamp, the other lamp is lit, three stored numbers are displayed, and in the display mode in which the two lamps are flashed together, the stored number is four. For example, the individual is displayed. Here, although two lamps (LEDs) are used here, the normal symbol operation memory lamp 33a may be configured using four lamps (LEDs). In this case, the number of working memories can be displayed by the number of lamps to be lit.

  The normal symbol operation memory lamp 33a changes to the display mode after being incremented one by one in the sense of memorizing the occurrence of an operation lottery trigger each time a game ball passes through the start gate 20. Then, every time a change of the normal symbol is started with the passage (up to 4) as a trigger, the display mode is changed by one by one. In this embodiment, when the normal symbol operation memory lamp 33a is not lit (the number of memories is 0), the game ball passes through the start gate 20 in a state in which the normal symbol can already start to change (during stop display). However, the display mode does not change. That is, the memorized number (maximum 4) represented by the display mode of the normal symbol operation memory lamp 33a represents the number of passages at which the variation of the normal symbol has not started yet.

  Further, the first special symbol display device 34 and the second special symbol display device 35 can display the variation state and the stop state of the special symbol by, for example, a 7-segment LED (with dots) (symbol display means, first symbol). Symbol display means, second symbol display means). In addition, the special symbol display device 34 may have a form in which a plurality of dot LEDs are arranged geometrically (for example, in a circular shape).

  Further, the first special symbol operation memory lamp 34a and the second special symbol operation memory lamp 35a have 0 to 4 each, for example, depending on a display mode constituted by a combination of extinction or lighting and blinking of two lamps (LEDs). Is stored (memory number display means). For example, in a display mode in which both lamps are turned off, 0 stored number is displayed, in a display mode in which one lamp is turned on, 1 stored number is displayed, and in a display mode in which the same one lamp is blinked. In the display mode in which two stored numbers are displayed, in addition to blinking one lamp, the other lamp is lit, three stored numbers are displayed, and in the display mode in which the two lamps are flashed together, the stored number is stored. For example, four are displayed.

  The first special symbol operation memory lamp 34a changes to the display mode after being incremented one by one in the sense of memorizing that every time a game ball enters the upper start winning opening 26. Every time the change of the special symbol is started, the display mode is decreased one by one every time the ball is entered (up to 4). Further, the second special symbol operation memory lamp 35a is incremented by one in the sense of memorizing that every time a game ball enters the variable start winning device 28 (lower start winning port). The display mode changes to a later display mode (up to a maximum of 4), and changes to the display mode after being reduced by one each time the change of the special symbol is started with the entry. In the present embodiment, when the first special symbol operation memory lamp 34a is not lit (the number of memories is 0), the first start symbol 26 is in a state where the first special symbol can already start to change (when stopped). Even if a game ball enters, the display mode does not change. In addition, when the second special symbol operation memory lamp 35a is not lit (the number of memories is 0), the variable start winning device 28 (lower start winning port) in a state in which the second special symbol can already start to change (during stop display). The display mode does not change even if a game ball enters the ball. That is, the number of memories (maximum of 4) represented by the display mode of each special symbol operation memory lamp 34a, 35a is the number of incoming balls for which the variation of the first special symbol or the second special symbol has not yet started. It represents the number of times.

  In addition, the game state display device 38 includes, for example, six LEDs respectively corresponding to a probability variation state display lamp 38a, a time reduction state display lamp 38b, a big hit type display lamps 38c, 38d, and 38e, and a launch position designation display lamp 38f. It is. In the present embodiment, the normal symbol display device 33, the normal symbol operation memory lamp 33a, the first special symbol display device 34, the second special symbol display device 35, the first special symbol operation memory lamp 34a, and the second special symbol are described. The symbol operation memory lamp 35a and the game state display device 38 are attached to the game board unit 8 in a state of being mounted on one integrated display board 89.

  The acoustic drive circuit 134 is, for example, a sound generator that includes a sound ROM, an acoustic control IC, an amplifier, and the like (not shown). The acoustic drive circuit 134 drives the upper speaker 54 and the lower speaker 56 to perform acoustic output. .

  In the present embodiment, a glass frame lighting board 136 is installed on the inner surface of the integrated door unit 4, and drive signals from the lamp driving circuit 132 and the acoustic driving circuit 134 pass through the glass frame lighting board 136 and various lamps 46. To 52 and speakers 54, 55, and 56. Also, the effect switching button 45 is connected to the glass frame decorating board 136, and when the player operates the effect switching button 45, the contact signal is sent to the effect control device 124 through the glass frame decorating board 136. Entered. In addition, although the example which connected the production | presentation switch button 45 to the glass-frame decoration board 136 is given here, when installing said saucer illumination board, the production switch button 45 is connected to the saucer illumination board. Also good.

  In addition, a panel board 138 is installed in the game board unit 8, and a movable body motor 57 is connected to the panel board 138 in addition to the panel lamp 53. The movable body motor 57 drives the movable body 40g via a link mechanism (not shown), for example. A drive signal from the lamp drive circuit 132 is applied to the panel lamp 53 and the movable body motor 57 via the panel illumination board 138, respectively.

  The liquid crystal display 42 is installed on the back side of the game board unit 8, and the display screen is visible through a substantially rectangular opening formed in the game board unit 8. Further, an inverter board 158 is installed on the back side of the game board unit 8, and the inverter board 158 generates an AC power source that is applied to a backlight (for example, a cold cathode tube) of the liquid crystal display 42. Further, an effect display control device 144 is installed on the back side of the game board unit 8, and the display operation by the liquid crystal display 42 is controlled by the effect display control device 144. The effect display control device 144 is equipped with a display control CPU 146 that is a general-purpose central processing unit and a circuit board (effect display control board) on which a VDP 152 that is a display processor is mounted. Among these, the display control CPU 146 is configured as an LSI in which semiconductor memories such as a ROM 148 and a RAM 150 are integrated together with a CPU core (not shown). The VDP 152 is configured as an LSI in which a semiconductor core such as an image ROM 154 and a VRAM 156 is integrated with a processor core (not shown). The VRAM 156 can use a part of the storage area as a frame buffer.

  The ROM 128 of the effect control CPU 126 stores a basic program related to effect control, and the effect control CPU 126 executes effect control according to this program. The production control includes production control using various lamps 46 to 53 and speakers 54, 55, and 56 as described above, and production control by image display using the liquid crystal display 42. . The effect control CPU 126 transmits basic information (for example, effect number) related to the effect to the display control CPU 146, and the display control CPU 146 that receives the information transmits a specific effect image based on the basic information. Control the display.

  The display control CPU 146 outputs a more detailed control signal to the VDP 152. Receiving this, the VDP 152 accesses the image ROM 154 based on the control signal, reads necessary image data therefrom, and transfers it to the VRAM 156. Further, the VDP 152 expands the image data in the frame buffer for each frame (still image per unit time) on the VRAM 156, and individually handles each pixel (full color pixel) of the liquid crystal display 42 based on the buffered image data.

  In addition, a power supply control unit 162 (power supply control means) is provided on the back side of the plastic frame assembly 7. The power supply control unit 162 has a built-in switching power supply circuit. When external power (for example, AC 24V) is taken from the island facility through the power cord 164, necessary power (for example, DC + 34V, + 12V) can be generated therefrom. The electric power generated by the power supply control unit 162 is distributed to the main control device 70, the payout control device 92, the effect control device 124, and the inverter board 158. Furthermore, power is supplied to the launch control board 108 via the payout control device 92, and power is supplied to the CR unit via the game ball rental device connection terminal board 120. The low voltage power for logic (for example, DC + 5V) is generated by a power supply IC (3-terminal regulator or the like) built in each device. Further, as described above, the power supply control unit 162 is grounded (grounded) to the island facility through the ground wire 166.

  The external terminal plate 160 is connected to the payout control device 92, and various external information signals generated by the main control device 70 (main control CPU 72) pass through the payout control device 92 to the external terminal plate 160.

The main control device 70 (main control CPU 72) and the payout control device 92 (payout control CPU 94) can output an external information signal to the outside of the pachinko machine 1 through the external terminal board 160. The signals output from the external terminal board 160 are collected by, for example, a hall computer (not shown) in a game hall. Here, the configuration via the payout control device 92 is taken as an example, but a configuration in which an external information signal is directly output from the main control device 70 to the external terminal board 160 may be used.

  The above is a configuration example relating to the control of the pachinko machine 1. Next, the configuration of the second variable winning device 31 will be described. 6 and 21 are exploded perspective views schematically showing the configuration of the second variable winning device 31. FIG. 6 and 21 show the configuration of the second variable winning device 31 from different angles. In the present embodiment, the second variable winning device 31 includes a winning opening decoration member 310, a flow path forming member 320, and a drive mechanism 330.

  That is, the second variable winning device 31 is roughly composed of three subunits. Specifically, each of the first subunit composed of the prize opening decoration member 310, the second subunit composed of the opening / closing member 31 a and the flow path forming member 320, the driving mechanism 330, and the second count switch 85. Formed of three subunits such as a third subunit.

  The first sub-unit opens a grand prize opening on the game board surface, and is configured to attach a prize opening decoration member 310 having the big prize opening to the board surface. The second subunit is designed to make it easy for a game ball flowing down the game area to enter the grand prize opening when the openable / closable opening / closing member 31a is in the open state, It is configured to prevent entry into the mouth. Furthermore, the flow path forming member 320 is configured to guide the third subunit while receiving the game ball that has entered the big winning opening. The third subunit operates the opening / closing member 31a of the connected second subunit by operating the drive mechanism 330, or the second count switch 85 detects the game ball guided from the second subunit. It has a configuration to do.

  First, the 1st subunit comprised from the decoration member 310 for winning a prize mouth is demonstrated.

[Decoration element for prize opening]
FIG. 7 is a perspective view showing the configuration of the winning opening decoration member, and FIG. 8 is an exploded perspective view showing the configuration of the winning opening decoration member.
The prize opening decoration member 310 includes a base plate 310a and a front cover 310b. The base plate 310a and the front cover 310b are made of, for example, a transparent (or translucent) resin material. Therefore, in the state installed in the game board unit 8, the decoration member 310 for winning a prize opening is comprised so that the inside can be visually recognized from the outside.

  The base plate 310 a is attached with its outer edge on the back side fixed to the board surface of the game board unit 8. A fitting port 310c is formed near the center of the back surface of the base plate 310a. The flow path forming member 320 is fitted into the fitting port 310c.

  Of the outer edge of the base plate 310a, an arc-shaped portion formed below is provided with a peripheral wall 310d. The base plate 310a is screwed in a state where the front cover 310b is aligned along the peripheral wall 310d. Further, on the upper edge of the outer edge of the base plate 310a, there are a portion where the peripheral wall 310d is provided and a portion where the peripheral wall 310d is not provided. That is, a peripheral wall is not provided at a position corresponding to the normal winning opening 24 or the big winning opening in a state where the base plate 310a and the front cover 310b are overlapped, and an opening is formed.

FIG. 9 is a cross-sectional view of the prize opening decorative member along the line IX-IX shown in FIG.
As shown in FIG. 7, the base plate 310a and the front cover 310b are provided with end portions 317a and 317b. Further, these end portions 317a and 317b correspond to portions that come into contact when the game ball falls, and by processing the shape of each end portion 317a and 317b, the game ball enters the variable winning device 31. It makes it easy to sphere. Specifically, the end 317a of the base plate 310a is inclined in the direction in which the game ball falls when viewed from the board surface, and the end 317b of the front cover 310b is inclined in the direction in which the game ball falls when viewed from the glass surface. The shape is different. As a result, when the game ball falls and comes into contact with the base plate 310a or the front cover 310b, the end balls 317a or 317b are rebounded toward the big winning opening. Therefore, by making the end portions of the base plate 310a and the front cover 310b inclined, it is possible to make it easier for a game ball to enter the big winning opening.

[See Fig. 7]
In addition, the decoration member 310 for the prize opening is decorated with various decorations on the surface of the front cover 310b according to the production mode during the special game, and various display devices are provided between the front cover 310b and the base plate 310a. Or can be provided. For example, an effect display device 200 may be arranged diagonally to the upper right of the normal winning opening 24. The display device for performance 200 counts the number of game balls that have entered the normal winning opening 24 during the big hit game, or when the game ball enters the normal winning opening 24 during the big hit game, the 7-segment LED is used. The effect design to be displayed can be variably displayed.

  Furthermore, a first chance lamp 300 for performance may be attached to the right side of the normal winning opening 24. The first chance lamp 300 performs an effect by light emission (turned on or off) of the built-in LED. For example, the first chance lamp 300 can be used as a lamp for instructing the player that a memory in the memory is generated. Here, in-memory Renso is a lottery for internal lottery related to special symbols that are stored without being consumed by winning at the top start winning opening 26 or the variable start winning device 28 before or during the big hit game. When the element (random number for winning determination) corresponds to winning, when the big hit game is finished, it indicates that the big winning game is continued by winning the internal lottery immediately.

  Furthermore, a second chance lamp 400 for performance may be attached to the lower side of the normal winning opening 24. The second chance lamp performs an effect by light emission (turned on or off) of the built-in LED. For example, the second chance lamp 400 can be used as a lamp for instructing the player that a special in-memory recreation area is generated (16 rounds and 16 rounds of big hits are continuously generated).

  Next, the 2nd subunit comprised from the opening / closing member 31a and the flow-path formation member 320 is demonstrated.

  10 and 11 are perspective views showing a configuration including a flow path forming member and an opening / closing member. FIG. 10 is a perspective view when the opening / closing member 31a is in the closed state, and FIG. 11 is a perspective view when the opening / closing member 31a is in the open state.

  The opening / closing member 31a is formed in a plate shape using a synthetic resin as a material, and includes a connecting arm 31p that transmits the movement from the drive mechanism to the end portion on the plate-like game board surface side. The opening / closing member 31a is displaced by operating these connecting arms 31p by the drive mechanism.

  For example, as shown in FIG. 10, the opening / closing member 31 a is displaced toward the glass surface and protrudes, so that the opening portion of the flow path forming member 320 can be covered. Therefore, when the state of being displaced and projecting toward the glass surface is set to the closed state, it is possible to prevent the game ball from entering the big winning opening.

  On the other hand, as shown in FIG. 11, the opening / closing member 31a is displaced to the game board surface side and retracted, whereby the opening portion of the flow path forming member 320 can be exposed. Therefore, when the state displaced and retracted to the game board surface side is set to the open state, it is possible to easily enter the game ball into the big winning opening.

  In addition, claw pieces 320p are formed on both sides at the end of the flow path forming member 320 to prevent the opening / closing member 31a from falling off after being incorporated into the flow path forming member 320.

[Flow path forming member]
Next, the flow path forming member 320 will be specifically described. FIG. 12 is a perspective view showing the configuration of the flow path forming member. In FIG. 12, the opening / closing member 31a shown in FIG. 6 is not shown.
As shown in FIG. 12, the flow path forming member 320 includes a main body portion 320a and a support portion 320b, and guides the game ball that has entered the above-mentioned big winning opening toward the second count switch 85. It has a spherical guide structure. An opening / closing member 31a is disposed between the main body portion 320a and the support portion 320b. The open / close member 31a horizontally moves toward the back side of the game board unit 8 from the state of protruding in the thickness direction of the game board unit 8 with respect to the game area 8a, thereby opening the big prize opening.

  The flow path forming member 320 is fixed in a state of being sandwiched between the winning opening decoration member 310 and the drive mechanism 330 in the completed state of the second variable winning device 31. At this time, the main body portion 320a is inserted through the fitting port 310c of the base plate 310a and is disposed between the base plate 310a and the front cover 310b. The configuration of the flow path forming member 320 will be described in more detail later with reference to FIGS.

[Configuration of flow path forming member]
FIG. 13 is an enlarged perspective view showing the guide member 322 shown in FIG.

  The flow path forming member 320 is composed of a main body part 320a and a support part 320b. The main body 320a has a hollow box shape, and openings 320c and 320d are formed on the front and top surfaces thereof. The opening 320c on the front side is fitted in the fitting port 310c of the prize-winning decorative member 310, and the periphery thereof contacts the back surface of the front cover 310b.

[Winner (Large Winner)]
Further, the opening 320d formed on the upper surface side opens upward when viewed in the direction in which the game ball flows down in a state where it is installed in the game board unit 8. The opening 320d serves as a big winning opening, and allows a game ball flowing down in the game area 8a to enter the game area 8a by changing from a closed state to an open state when a predetermined condition is satisfied. Hereinafter, the “opening 320d” on the upper surface side is referred to as a “large winning opening 320d”. The main body 320a is also formed with a partial opening 320g on the back surface facing the opening 320c on the front side, and is opposed to the entrance of the ball guiding path 332d provided in the case body 332.

[First channel, second channel]
A first channel 320e and a second channel 320f are formed on the bottom surface of the main body 320a.
The first flow path 320e is formed in the special winning opening 320d, and guides the entered game ball along a downward slope in a direction along the board surface. The second flow path 320f is formed to be connected to the downstream end of the first flow path 320e, and the game ball that has entered the big winning opening 320d along the downward slope from the board surface to the back direction is transferred to the back side of the game board unit 8. invite. As shown in FIG. 12, a step 320h is formed between the first flow path 320e and the second flow path 320f, and the second flow path 320f is at a position one step lower than the first flow path 320e. Is formed.

[Guide member]
In the present embodiment, a guide member 322 is provided on the upstream side of the second flow path 320f. The guide member 322 directs the traveling direction of the game ball that has passed through the special winning opening 320d to the downstream side of the second flow path 320f. A plurality of surfaces are formed on the guide member 322, and these are constituted by an upper surface 322a, an inclined surface 322b, a winning opening side inclined surface 322c, a flow channel side inclined surface 322d, and an orthogonal surface 322e.

  Specifically, as shown in FIG. 13, the upper surface 322a is formed on the upper surface of the guide member 322 when the flow path forming member 320 is viewed in the height direction. The inclined surface 322b is formed continuously with the upper surface 322a, and is inclined downward toward the first flow path 320e.

[Winning side inclined surface]
The winning opening side inclined surface 322c is formed to be continuous with the upper surface 322a similarly to the inclined surface 322b, and is disposed downstream of the inclined surface 322b in the second flow path 320f. In the present embodiment, the winning opening side inclined surface 322c is inclined in the direction toward the downstream side of the second flow path 320f with respect to the falling direction of the game ball directed downward from the large winning opening 320d.

(Inclined surface on the flow path side)
In addition, the channel-side inclined surface 322d is formed continuously to the prize-winning-side inclined surface 322c, and the second channel with respect to the advancing direction of the game ball rolling along the descending slope of the first channel 320e. It is inclined in the direction toward the downstream of 320f.

(Orthogonal plane)
The orthogonal surface 322e is formed continuously with the inclined surface 322b, and is disposed on the upstream side of the second flow path 320f with respect to the flow path side inclined surface 322d. The orthogonal plane 322e is orthogonal to the advancing direction of the game ball that rolls through the first flow path 320e through the special winning opening 320d.

  FIG. 14 is a front view of the flow path forming member 320 shown in FIG. The bottom surface of the main body portion 320a is inclined while being installed in the game board unit 8.

  As shown in FIG. 14, the bottom surface of the flow path forming member 320 (first flow path 320e) is inclined downward from the right side wall toward the left side wall. When the game ball that has entered the big prize opening 320d falls to the bottom surface, it rolls toward the left side wall along the inclination of the first flow path 320e. At this time, the game ball collides with the guide member 322, for example, and the rebound direction is directed to the downstream side of the second flow path 320f.

  FIG. 15 is a cross-sectional view of the flow path forming member 320 along the line XV-XV shown in FIG. The white arrow shown in FIG. 15 indicates the traveling direction of the game ball rolling on the first flow path 320e.

(Inclined surface on the flow path side)
The guide member 322 has a channel-side inclined surface 322d that is inclined by A1 in the direction toward the downstream of the second channel 320f with respect to the traveling direction of the game ball rolling along the downward inclination of the first channel 320e. Is formed. Therefore, when the game ball collides with the channel-side inclined surface 322d of the guide member 322, the rebound direction is directed toward the downstream of the second channel 320f, not the first channel 320e.

  In addition, the guide member 322 is formed with an orthogonal surface 322e that is orthogonal to the traveling direction of the game ball that rolls along the downward slope of the first flow path 320e. The width dimension W of the orthogonal surface 322e is smaller than the radius of the game ball. Therefore, when the game ball rolling in the first flow path 320e collides with the orthogonal plane 322e, the traveling direction of the center of gravity (center) of the game ball is guided to the second flow path 320f along the flow path side inclined surface 322d. The

  FIG. 16 is a longitudinal sectional view of the flow path forming member 320 along the line XVI-XVI shown in FIG. The white arrow shown in FIG. 16 indicates the falling direction of the game ball directed downward from the big winning opening 320d.

[Winning side inclined surface]
As shown in FIG. 16, the winning opening side inclined surface 322c is inclined by A2 in the direction toward the downstream side of the second flow path 320f with respect to the falling direction of the game ball. At this time, the channel side inclined surface 322d is also inclined by A2 in the direction toward the downstream side of the second channel 320f with respect to the falling direction of the game ball, similarly to the prize port side inclined surface 322c. For this reason, the game ball that has collided with the upper surface 322a of the guide member 322 as viewed in the falling direction of the game ball is guided to the downstream side of the second flow path 320f along the inclination of the winning opening side inclined surface 322c.

  Thus, in this embodiment, by providing the guide member 322, it is possible to smoothly switch the flow path without retaining the game ball that has entered the big winning opening 320d.

  Finally, the third subunit composed of the drive mechanism 330 and the second count switch 85 will be described. Before describing each component, it will be described how the opening / closing member 31a of the second subunit is displaced by the actuation of the drive mechanism 330 of the third subunit. 17 and 18 are exploded perspective views showing a configuration including the flow path forming member, the opening / closing member, and the drive mechanism. FIG. 17 illustrates a case where the opening / closing member 31a connected to the drive mechanism 330 is in an open state. On the other hand, FIG. 18 illustrates a case where the opening / closing member 31 a connected to the drive mechanism 330 is in a closed state.

  As shown in FIG. 17, the drive mechanism 330 includes a case body 332, and the case body 332 includes an upper case member 332a and a lower case member 332b. A pair of elliptic grooves 332c are formed on the upper surface of the upper case member 332a. In addition, a pair of external link arms 31b are disposed on the upper surface of the upper case member 332a, and through holes are formed at the ends of the external link arms 31b. The through holes are located on the elliptical groove 332c. Is arranged to work. The connecting arm 31p of the opening / closing member 31a of the second subunit passes through the through hole of the external link arm 31b and is supported in a freely displaceable manner in an elliptical groove 332c on the upper surface of the upper case member 332a. The connecting arm 31p of the opening / closing member 31a moves in the longitudinal direction of the elliptical groove 332c together with the other end of the external link arm 31b as the external link arm 31b rotates. Accordingly, the opening / closing member 31a slides between the upper surface of the main body portion 320a and the support portion 320b, thereby opening or closing the big prize opening formed on the upper surface of the main body portion 320a.

  For example, as shown in FIG. 17, when the through-hole of the external link arm 31b is operated and moved to the game board surface side of the elliptical groove 332c, the connection arm 31p of the opening / closing member 31a is displaced to the game board side accordingly. The opening / closing member 31a is retracted to the game board side so as to open the special winning opening 31. Thereby, the big prize opening formed in the upper surface of the main-body part 320a is open | released.

  Further, as shown in FIG. 18, when the through hole of the external link arm 31b is operated and moved to the glass surface side of the elliptical groove 332c, the connecting arm 31p of the opening / closing member 31a is displaced to the glass surface side accordingly. The opening / closing member 31a protrudes toward the glass surface so as to cover the special winning opening 31. Thereby, the big prize opening formed in the upper surface of the main-body part 320a is obstruct | occluded.

  Next, the driving mechanism 330 of the third subunit will be specifically described. 19 and 20 are exploded perspective views showing the internal structure of the drive mechanism. FIG. 19 illustrates a case where the opening / closing member 31a connected to the drive mechanism 330 is in a closed state. On the other hand, FIG. 20 illustrates a case where the opening / closing member 31a connected to the drive mechanism 330 is in an open state.

(Drive mechanism)
Inside the case body 332, a second big prize winning solenoid 97 and an internal link arm 31x are mounted as a drive source for sliding the opening / closing member 31a.

  A pair of external link arms 31b are disposed on the upper surface of the upper case member 332a. A fan-shaped gear is formed at one end portion of the external link arm 31b, that is, a tip portion viewed in a direction in which the external link arms 31b face each other, and meshes with each other. Moreover, the lower surface is connected with the internal link arm 31x via the upper case member 332a at the front-end | tip part of one external link arm 31b among a pair of external link arms 31b.

  The other end of the external link arm 31b is disposed to face the elliptical groove 332c, and the connecting arm 31p of the opening / closing member 31a is connected from above. Further, the inner link arm 31x is rotatably supported at a position facing the elliptical groove 332c.

  A fixing member 31c is provided above the external link arm 31b (see FIG. 18 or FIG. 17). The fixing member 31c is fixed to the upper case member 332a and fixes the vicinity of the center of each external link arm 31b. The external link arm 31b is supported rotatably around a position fixed by the fixing member 31c.

  Further, when the second grand prize winning solenoid 97 is driven, the internal link arm 31x is rotated. As the internal link arm 31x rotates, the external link arm 31b connected thereto rotates the upper surface of the upper case member 332a.

  For example, as shown in FIG. 19, when the second big prize opening solenoid 97 is in an inoperative state, the iron core 97c provided protruding from the solenoid is fixed in a state of being pushed back by a spring 97b. ing. On the other hand, when the second big prize opening solenoid 97 is driven as shown in FIG. 20, the iron core 97c is fixed while being pulled into the second big prize opening solenoid. Accordingly, when the second big prize opening solenoid 97 is driven and the iron core 97c is moved, the internal link arm 31x rotates, and the external link arm 31b connected thereto rotates with the rotation of the upper case member 332a. The top surface will be rotated.

[Ball taxiway]
On the left side of the case body 332, a ball guiding path 332d is formed. Further, a second count switch 85 is installed on the back side of the ball guiding path 332d. The ball guiding path 332 d is a guiding path for guiding the game ball rolling on the flow path forming member 320 to the second count switch 85. The second count switch 85 detects the game ball that has passed through the ball guiding path 332d. A discharge port (not shown) is formed on the lower surface of the lower case member 332b, and the game ball that has passed through the second count switch 85 on the ball guide path 332d passes through the out passage assembly (not shown) from the discharge port. It is discharged out of the frame from the back side of 1, and further joins a replenishment route of an island facility (not shown).

  The LED unit 334 may be provided on the lower surface of the lower case member 332b. The LED unit 334 includes a substrate 334a, a plurality of LED chips 334b, and connection terminals (not shown). The LED chip 334b is mounted on the surface (mounting surface) of the substrate 334a, and is connected to an antenna pattern (not shown) formed on the substrate 334a. The connection terminal 334c is mounted on the surface opposite to the mounting surface, and is electrically connected to each LED chip 334b through the antenna pattern. Further, the connection terminal is connected to the panel electrical decoration substrate 138. For example, the LED unit 334 causes each LED chip to emit light (turned on, turned off, etc.) in accordance with an effect during a special game. Thereby, for example, light is applied to the back surface of the flow path forming member 320.

Next, a description will be given of a second variable winning device that is assembled by connecting three subunits (first to third subunits).
21 and 22 are exploded perspective views showing the configuration of the second variable winning device. As shown in FIGS. 21 and 22, the protrusions 310 u and 310 v formed at two locations of the first subunit (decoration decorative member) 310 and the end of the second subunit (flow path forming member) 320. The channel forming member 320 of the second subunit is fitted into the fitting opening 310c of the first subunit while aligning the position adjusting units 320u and 320v provided in the unit, so that the first subunit and the second subunit The subunits are connected.

  Further, the base plate 310a of the first subunit is provided with two cylinders 310s and 310t in which screw threads are formed. The cylinders 310s and 310t of the first subunit are fastened with screws 370s and 370t from the back of the fastening portions 337s and 337t while the fastening portions 337s and 337t formed at the end of the third subunit are housed inside. By doing so, the first subunit and the third subunit are fastened.

  Therefore, the second variable winning device 31 is completed by forming or assembling the first subunit, the second subunit, and the third subunit independently, and connecting and assembling the subunits. It becomes. Thus, since each subunit can be formed independently, it can be variously modified for each subunit. For example, the decoration and shape of the first subunit can be changed corresponding to the gaming machine, or the position on the gaming board surface can be changed. For example, it is possible to change the opening width of the big winning opening of the second subunit or the inclination of the flow path. For example, by changing the link mechanism of the third subunit, it can be changed vertically or horizontally. Specifically, the decoration of the first subunit can be changed corresponding to the model (type) of the gaming machine and various game characteristics, and the second subunit and the third subunit can be made common.

  In this way, each subunit can be produced independently corresponding to each model (type) of gaming machine and various gaming properties, so the versatility of each model can be improved, and each subunit can be improved. Since the units are simply connected and combined, it is possible to improve the assembling property and the productivity. Note that modifications of the first subunit and the second subunit will be described later as a second embodiment.

[Sphere guide structure]
In the following, the structure from when a game ball flowing down the game area 8a during a special game enters the big prize opening 320d until it is discharged to the discharge port will be described.

  FIG. 23 is a perspective view showing a state in which the flow path forming member 320 and the drive mechanism 330 are combined with each other. When the special winning opening 320d is opened in the special game, the game balls flowing down the gaming area 8a can enter the special winning opening 320d. Note that FIGS. 23 to 27 show three-dimensional coordinate axes. The X axis indicates the direction along the left-right direction of the game board unit 8. The Y axis indicates the direction along the vertical direction of the game board unit 8. Further, the Z axis indicates the direction along the thickness direction of the game board unit 8.

As shown in FIG. 1, due to the configuration of the game area 8a (board surface), when a game ball is to be entered into the normal winning opening 24 or the second variable prize winning device 31, the right-side area (right-handed) in the game area 8a. A game ball is shot into the area. When the game ball flowing down the right-handed area enters the big winning opening 320d, it falls to the bottom surface (first flow path 320e) of the main body 320a disposed at the lower position.
The game ball that has dropped into the first flow path 320e is guided to the second flow path 320f while rolling in the tilt direction.

  24 is a front view of the flow path forming member 320 and the drive mechanism 330 shown in FIG. The arrow shown in FIG. 23 represents the traveling direction of the game ball.

  In FIG. 24, illustration of the prize opening decoration member 310 is omitted, but the flow path forming member 320 is installed in the game board unit 8, and the front opening 320 c of the prize opening decoration member 310 is provided. It is configured to be visible from the outside through the front cover 310b (and the window 4a).

  Therefore, the player can visually recognize how the plurality of game balls that have entered the special winning opening 320d roll in the first flow path 320e during the special game. As a result, the player can be given a sense of accomplishment and satisfaction with the special game.

  25 is a cross-sectional view of the flow path forming member 320 and the drive mechanism 330 along the line XXV-XXV shown in FIG. In addition, the solid line arrow shown in FIG. 24 represents the advancing direction of a game ball similarly to FIG.

  When the game ball rolling in the first flow path 320e collides with the guide member 322, its traveling direction is guided to the inclination direction of the flow path side inclined surface 322d and switched to the downstream side of the second flow path 320f. In addition, when the game ball that has passed through the special winning opening 320d directly collides with the upper surface of the guide member 322, or when the game ball rolling on the first flow path 320e rides on the upper surface 322a of the guide member 322, the game ball The traveling direction is guided to the inclination direction of the winning opening side inclined surface 322c and switched to the downstream side of the second flow path 320f. In any case, the game ball whose traveling direction is switched is guided to the ball guiding path 332d through the second flow path 320f.

  FIG. 26 is a diagram schematically showing an operation principle for switching the traveling direction of the game ball shown in FIG. 25 to the second flow path 320f. The X axis shown in FIG. 26 represents the left-right direction of the game board unit 8, and the Y axis represents the up-down direction of the game board unit 8. The Z axis indicates the thickness direction of the game board unit 8. The white arrow shown in FIG. 26 represents the traveling direction of the game ball.

  When the game ball rolling in the first flow path 320e along the X-axis direction collides with the guide member 322, the traveling direction is directed (guided) in the Z-axis direction. That is, when it collides with the orthogonal surface 322e of the guide member 322, the game ball rolls along the flow path side inclined surface 322d connected to the orthogonal surface 322e. The channel-side inclined surface 322d is inclined to the downstream side (Z-axis direction) of the second channel with respect to the X axis. For this reason, when the game ball collides with the guide member 322, the traveling direction thereof is guided downstream of the second flow path 320f along the flow path side inclined surface 322d.

  Further, the width dimension W of the orthogonal surface 322e viewed in the Z-axis direction is sufficiently smaller than the radius R of the game ball. For this reason, when the game ball collides with the orthogonal surface 322e, the traveling direction of the center of gravity (center) is guided in a direction along the flow path side inclined surface 322d. Therefore, the traveling direction of the game ball rolling on the first flow path can be switched smoothly.

  FIG. 27 is a longitudinal sectional view of the flow path forming member 320 and the drive mechanism 330 along the line XXVII-XXVII in FIG. The solid-line arrows shown in FIG. 27 indicate the traveling direction of the game ball as in FIGS.

The game ball guided to the second flow path 320f by the guide member 322 rolls in the inclination direction of the second flow path 320f and is guided to the ball guide path 332d. In the ball guide path 332d, the game ball is guided by the guide ribs 332e formed above and below and passes through the second count switch 85. At this time, the second count switch 85 detects the passage of the game ball.
The game balls that have passed through the second count switch 85 are discharged from the back side of the pachinko machine 1 through the outlet passage 332f formed in the lower case member 332b to the outside of the frame from the back side of the pachinko machine 1, and further to the supply path of the island equipment not shown. Join.

  As described above, according to the pachinko machine 1 of the present embodiment, the trajectory of the game ball from the time when the ball is entered into the big winning opening 320d to the time when the second flow path 320f is reached via the first flow path 320e. Can be visually recognized. For this reason, in the big hit game, by letting the player visually recognize the trajectory of the game ball that has entered the big prize opening, the player can feel a sense of achievement and a sense of security that the game ball has entered the big prize opening. Can be given against.

  The traveling direction of the game ball that has entered the winning opening is smoothly switched toward the second flow path when the game ball collides with the guide member. For this reason, since the game ball can be guided to the count switch without staying in the attacker, the trajectory of the game ball can be stabilized.

  The guide member 322 is formed with a channel-side inclined surface 322d that inclines in the direction toward the downstream of the second channel with respect to the traveling direction of the game ball rolling along the downward inclination of the first channel. Thus, the traveling direction of the game ball rolling on the first flow path 320e can be smoothly guided in the back direction.

  Further, the guide member 322 is formed with a winning-port-side inclined surface 322c that inclines in a direction toward the downstream of the second flow path 320f with respect to the falling direction of the game ball that has passed through the large winning port 320d. The traveling direction of the game ball that directly passes through the winning opening 320d and directly contacts the guide member 322 can be guided in the back direction.

  Next, a game ball that enters the variable winning device 31 is sandwiched between the front cover 310b and the opening / closing member 31a of the prize opening decoration member 310, and the game ball is stagnated on the game board surface (so-called ball biting). A structure for preventing this will be described. Specifically, when the big hit game is started and the operation of the variable winning device 31 is started, the opening / closing member 31a is displaced to the open position (withdrawn into the flow path forming member 320), and the big winning opening 320d is opened. Each time one round game in the big hit game is completed, the opening / closing member 31a is displaced to the closed position (projecting from the flow path forming member 320), and the big winning opening 320d is once closed. When the next round game is started, the opening / closing member 31a is again displaced to the open position, and when the big hit game is finished, the opening / closing member 31a is finally displaced to the closed position (projecting from the flow path forming member 320). The big prize opening 320d is closed. Here, when the opening / closing member 31a is displaced from the open position to the closed position, the opening / closing member 31a, the front cover 310b, The structure prevents the game ball from being caught between the balls, thereby preventing the occurrence of the biting of the ball. Note that a game ball entering the big prize opening 320d assumes a case where not all of the game balls enter the big prize opening 320d. That is, it is assumed that even if a part of the game ball enters the big prize opening 320d, it does not enter, but enters the lower part of the opening / closing member 31a and the whole game ball is accommodated in the big prize opening 320d. doing.

  FIG. 28 is a perspective view showing a flow path forming member, an opening / closing member, and a prize opening decoration member connected to each other. FIG. 28 shows a state where the opening / closing member 31a is displaced to the closed position (a state protruding from the flow path forming member 320).

  As shown in FIG. 28, a large winning opening 320d is formed between the base plate 310a of the winning opening decorative member 310 and the front cover 310b. Further, a standing board 310r is provided on the surface on the game board surface side of the front cover 310b so as to face the opening / closing member 31a (along the special winning opening 320d). Therefore, the substantial size of the big winning opening 320d indicates that it is between the standing plate 310r and the base plate 310a.

  Thus, by providing the standing plate 310r on the front cover 310b, the parallelism of the front cover 310b can be improved and distortion can be suppressed. Therefore, it is possible to suppress and widen the opening width of the special winning opening 320d (between the front cover 310b and the base plate 310a).

  In addition, by providing the standing plate 310r on the front cover 310b along the big prize opening 320d, the game ball is pinched (the ball is bitten) when the opening / closing member 31a is displaced to the closed position. Can be reduced. Specifically, when only the front cover 310b is provided without the standing plate 310r, the relationship between the front cover 310b and the opening / closing member 31a can be replaced with the relationship between the surface and the line, and the game ball comes into contact. There are many more places. On the other hand, when the standing plate 310r is provided, the relationship between the standing plate 310r and the opening / closing member 31a can be replaced with the relationship between the lines, and the number of places where the game ball contacts is less than the relationship with the surface. ing. Therefore, the phenomenon that a game ball is pinched, such as a ball bite, indicates that the relationship between the line and the line is less likely to occur than the relationship between the surface and the line because there are fewer places where the game ball contacts the game ball. In addition, the occurrence of ball biting can be suppressed by providing the standing plate 310r. In addition, it is clear that the ball biting is generated and the state is maintained, that is, the game ball is stagnated due to the relationship between the surface and the line, so that the ball biting occurs in the standing plate 310r. As soon as possible. Specifically, even if the game ball is caught between the standing plate 310r and the opening / closing member 31a, the game ball can be immediately moved above or below the opening / closing member 31a.

  Further, a gap 37s is provided between the opening / closing member 31a located at the closed position and the standing plate 310r. By providing the gap 37s, dust such as dust or dust can be removed from the gap, and dust can be prevented from accumulating and adhering. Specific contents will be further described later with reference to another drawing.

FIG. 29 is a cross-sectional view of the special winning opening along line XXIX-XXIX shown in FIG.
As shown in FIG. 29, the flow path forming member 320 is fitted from the fitting opening of the base plate 310a of the winning hole decoration member 310, and the opening / closing member 31a is displaced to the closed position in a state of protruding from the flow path forming member 320. A standing plate 310r is provided on the front cover 310b so as to face the opening / closing member 31a. Further, the opening / closing member 31a and the standing plate 310r in the closed position are not in contact with each other, and a clearance 37s is provided. Therefore, it represents that the big winning opening 320d is between the standing plate 310r and the base plate 310a. The size of the special winning opening 320d, that is, the distance between the standing plate 310r and the base plate 310a is set to a length (for example, about 12 mm) that allows a game ball to pass sufficiently (for example, about 12 mm). The length of the gap 37s between the open / close member 31a in the closed position from the standing plate 310r is set to about 2 mm, and the length from the base plate 310a to the front cover 310b is set to about 14 mm).

FIG. 30 is an enlarged cross-sectional view of the standing plate and the opening / closing member that form the gap shown in FIG.
As shown in FIG. 30, the surfaces of the standing plate 310r and the opening / closing member 31a that form the gap 37s are formed of a plurality of inclined surfaces. For example, the surface of the front end portion of the standing plate 310r is composed of an inclined surface 310r1 that is gently inclined and an inclined surface 310r2 that is greatly inclined. On the other hand, the surface of the front end portion of the opening / closing member 31a is composed of a parallel surface 31a1 parallel to the base plate 310a and the front cover 310b and an inclined surface 31a2 which is greatly inclined without being inclined. Specifically, the inclined surface 310r1 of the standing plate 310r is inclined at an angle Θ1 with respect to the surface of the front cover 310b, and the inclined surface 310r2 is inclined at an angle Θ2. On the other hand, the parallel surface 31a1 of the opening / closing member 31a is parallel to the front cover 310b, and the inclined surface 31a2 is inclined at an angle Θ4.

  Thus, the tip of the standing plate 310r composed of the inclined surface 310r1 whose upper surface has the gentle inclination angle Θ1 and the inclined surface 310r2 whose lower surface has the large inclination angle Θ2, and the upper surface has the parallel surface 31a1 and the lower surface The front end portion of the opening / closing member 31a constituted by the inclined surface 31a2 having a large inclination angle Θ4 has a structure spreading downward. Therefore, even if the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a and bites the ball, the game ball spreads downward, so that the game ball is easy to move downward. It is easy to enter the winning slot 320d.

  Further, regarding the configuration of the tip of the standing plate 310r, the upper surface is an inclined surface 310r1 having a gentle inclination angle Θ1. As described above, since the upper surface has a gentle inclination angle, it is possible to prevent the standing plate 310r from being lost even when the game ball collides when it falls.

  Further, the lower surface of the tip portion of the standing plate 310r is an inclined surface 310r2 having a large inclination angle Θ2. Thus, by forming an inclined surface having a larger inclination angle than the inclined surface 310r1 on the upper surface, the contact surface on which the game ball can come into contact with the standing plate 310r can be reduced. Therefore, it is possible to reduce the contact surface of the upright plate 310r by making it difficult to contact the lower surface (inclined surface 310r2) and contacting only the upper surface (inclined surface 310r1). Therefore, even if the game ball is pinched between the standing plate 310r and the opening / closing member 31a and bites the ball, the ball bite can be eliminated immediately without stagnation on the spot.

  By limiting the contact surface of the upright plate 310r to the inclined surface 310r1 on the upper surface, the surface to be applied can be clarified when applying a lubricant (lubricating oil) as a measure against ball engagement.

  Further, the lower surface of the distal end portion of the opening / closing member 31a is an inclined surface 31a2 having a large inclination angle Θr. In this way, by forming an inclined surface having a larger inclination angle than the flat surface 31a1 on the upper surface, it is possible to reduce the contact surface where the game ball can contact the opening / closing member 31a. It is possible to reduce the contact surface of the opening / closing member 31a by making it difficult to contact the lower surface (inclined surface 31a2) and contacting only the upper surface (plane 31a1). Therefore, even if the game ball is pinched between the standing plate 310r and the opening / closing member 31a and bites the ball, the ball bite can be eliminated immediately without stagnation on the spot.

Next, the behavior of the game ball when entering the big winning opening 320d will be described.
FIG. 31 to FIG. 34 are diagrams for explaining the behavior of the game ball when entering the big winning opening 320d. FIG. 31 is a diagram for explaining the behavior of the game ball when entering the big prize opening 320d when the opening / closing member 31a is in the closed position, and FIG. 32 is a diagram when the opening / closing member 31a is in the open position. It is a figure explaining behavior of a game ball at the time of entering a grand prize opening 320d. FIG. 33 and FIG. 34 are diagrams for explaining the behavior when the game ball is caught between the standing plate 310r and the opening / closing member 31a and bites the ball immediately before entering the big winning opening 320d.

  As shown in FIG. 31, when the opening / closing member 31 a is displaced to the closed position protruding from the flow path forming member 320, the opening / closing member 31 a can be used even if the game ball falls toward the big winning opening 320 d. This prevents the entry to the big winning opening 320d. And it will move on the opening-and-closing member 31a along the downward direction.

  On the other hand, as shown in FIG. 32, when the opening / closing member 31a is displaced to the open position in which the opening / closing member 31a is retracted into the flow path forming member 320, when the game ball falls toward the big winning opening 320d, the opening / closing member 31a Will enter the grand prize opening 320d without being obstructed. Then, the inside of the flow path forming member 320 is guided, and the passage is detected by the second count switch 85 provided on the guide path in the drive mechanism 330.

  In addition, as shown in FIG. 33, when the game ball falls toward the big prize opening 320d and the opening / closing member 31a protrudes from the flow path forming member 320 just before entering the big prize opening 320d, The game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, and the ball is bitten. Assuming that the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, the center of the game ball is located above the standing plate 310r and the opening / closing member 31a.

  The game ball caught between the standing plate 310r and the opening / closing member 31a receives a force that the opening / closing member 31a tends to displace toward the closed position. That is, a force that pushes the game ball upward is received. As a result, even if the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, immediately after that, the game ball is pushed up above the opening / closing member 31a, and the ball entering the winning prize opening 320d is hindered. Become.

  On the other hand, as shown in FIG. 34, when the game ball falls toward the big prize opening 320d and the opening / closing member 31a protrudes from the flow path forming member 320 just before entering the big prize opening 320d, The game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, and the ball is bitten. Assuming that the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, the center of the game ball is located below the standing plate 310r and the opening / closing member 31a.

  The game ball caught between the standing plate 310r and the opening / closing member 31a receives a force that the opening / closing member 31a tends to displace toward the closed position. In other words, a force to push down the game ball is received. As a result, even if the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, immediately after that, the game ball is pushed down below the opening / closing member 31a and enters the grand prize opening 320d.

  As shown in FIG. 34, when a game ball is sandwiched between the standing plate 310r and the opening / closing member 31a, the game ball comes into contact with the inclined surface 310r1 on the upper surface of the standing plate 310r. Therefore, by previously applying a lubricant (lubricating oil) to the inclined surface 310r1, the game ball can be made slippery and can be made difficult to be held between the standing plate 310r and the opening / closing member 31a. Therefore, even if the game ball is pinched between the standing plate 310r and the opening / closing member 31a and bites the ball, the ball bite can be eliminated immediately without stagnation on the spot. In addition, it is possible to make it difficult for dust and dirt to adhere to the contact surface of the standing plate 310r by applying a coating agent having an excellent dustproof effect to the inclined surface 310r1, and as a result, the ball biting is eliminated immediately. You can also

  As described above, the standing plate 310r is provided on the front cover 310b so as to face the opening / closing member 31a, and further, the clearance 37s is provided between the standing plate 310r and the opening / closing member 31a. Can be prevented from accumulating or adhering in the vicinity of the grand prize winning opening 320d, and the surface of the standing plate 310r and the opening / closing member 31a can be kept slippery (specifically, the surface roughness and the friction coefficient). be able to. Further, the contact surface when the game ball is sandwiched between the standing plate 310r and the opening / closing member 31a can be reduced by inclining the tip portions of the standing plate 310r and the opening / closing member 31a so as to expand downward. it can. Further, by inclining the standing plate 310r in two stages, it is possible to prevent the standing plate 310r from being lost due to a collision of a game ball, and further, by limiting the position where the ball is bitten (contact surface), lubrication is achieved. The application surface of the agent (lubricating oil) can be clarified. From the above, even if the game ball is pinched between the standing plate 310r and the opening / closing member 31a and bites the ball, the ball bite can be immediately released without causing the game ball to stagnate on the spot, The player is not frustrated, and a decrease in interest in the game can be suppressed.

  Further, the structure, board surface configuration, specific numerical values and the like of the pachinko machine 1 are preferable examples including those shown in the drawings, and it goes without saying that these can be appropriately modified.

  For example, the winning device of the present invention may be applied to the first variable winning device 30 or the variable start winning device 28. In addition, the second count switch 85 is provided in the third subunit, but may be provided on the second flow path 320f in the second subunit. In addition, the opening / closing member 31a is provided in the second subunit so as not to fall off by the claw piece 320p, but the opening / closing member 31a may be provided in the third subunit so as not to fall off.

  For example, the structure of the front end portion of the standing plate 310r, the opening / closing member 31a, and the front end portion may be reversed, or may have a structure with more inclined surfaces. Specifically, the surface of the front end portion of the standing plate 310r is composed of a parallel surface parallel to the base plate 310a and the front cover 310b without being inclined, and a greatly inclined inclined surface, and the distal end of the opening / closing member 31a. The surface of the part may be composed of a gently inclined inclined surface and a greatly inclined inclined surface, and may have a structure spreading downward. Moreover, although the surface of the front-end | tip part of the standing board 310r and the surface of the front-end | tip part of the opening-and-closing member 31a incline in two steps, you may incline in three steps or four steps, respectively.
