  The gaming machine main body 90 includes a gaming board side assembly in which various components are assembled to the gaming board 11 shown in FIG. 4, and an inner frame 75 shown in FIG. 4 (corresponding to the “game board housing frame” of the present invention). Two assemblies, an inner frame side assembly formed by assembling various parts, are assembled.

  First, the components constituting the game board side assembly will be described. The game board 11 is made of a substantially rectangular plate material made of wood. As shown in FIG. 1, a guide rail 12 is attached to the front surface of the game board 11, and the inside of the guide rail 12 is a game area R1. A display device 13 is provided almost at the center of the game area R1, and below the display device 13, an upper start winning port 14A, a lower start winning port 14B, a big winning port 15 and an out port 16 are arranged in order from the top. They are arranged side by side at intervals. A start gate 18 and a windmill 17 are provided on the left side of the display device 13 in the game area R1, and general winning ports 20, 21 are provided along the guide rails 12 on the left and right sides of the starting winning ports 14A, 14B. Is provided. In addition to these winning holes, a plurality of nails (not shown) stand up in the game area R1. The front surface of the game board 11 corresponds to “one board surface in the board thickness direction of the game board” in the present invention.

  Each part on the front surface of the game board 11 will be further described in detail. The display device 13 is composed of a liquid crystal module (specifically, a TFT-LCD module), and from a rear surface side of the game board 11 with respect to a display mounting hole (not shown) formed through the central portion of the game board 11. It is attached. A frame-shaped decorative frame 23 (see FIG. 1) is mounted on the display mounting hole from the front side of the game board 11, and the periphery of the display device 13 is surrounded by the decorative frame 23.

  The start gate 18 has a gate-like structure through which game balls can pass through, and the passed game balls are detected by a gate switch (not shown) built in the start gate 18. Based on this detection signal, the normal symbol is displayed in a variable manner on the normal symbol display unit 38.

  The normal symbol display unit 38 is provided below the windmill 17. The normal symbol display part 38 is comprised by the 7 segment LED display which can display the 2-digit number as a normal symbol.

  When the game ball passes through the start gate 18, the normal symbol display unit 38 displays a two-digit number (normal symbol) variably over a predetermined period, and then stops display. For example, when the two-digit numbers that are stopped and displayed are the same (both eyes), the lower start winning opening 14B, which will be described below, is in an open state, so that the game ball is easy to win. In addition, the game balls that have passed through the start gate 18 while the normal symbol display unit 38 is variably displayed are cumulatively counted (so-called “hold”) up to a predetermined number (for example, four). Note that the number of holds is notified to the player by the number of lights of the LED for the number of holds provided in the game area R1.

  Each of the upper and lower start winning openings 14A and 14B has a so-called pocket structure and is open upward. The game balls that have entered the start winning ports 14A and 14B are collected on the back side of the game board 11 through through holes (not shown) provided in the game board 11.

  The upper opening of the upper start winning opening 14A arranged on the upper side is sized to receive game balls one by one. On the other hand, the lower start winning opening 14B disposed on the lower side is disposed directly below the upper start winning opening 14A, and movable wings 14C and 14C are provided on both the left and right sides of the upper surface opening.

Yes. Further, the upper space of the lower start winning opening 14B is always surrounded by the members constituting the upper start winning opening 14A and the movable wings 14C and 14C in the standing state so that the game ball does not enter.

  On the other hand, when the two-digit number on the normal symbol display section 38 is stopped and displayed with a doublet and the release condition is satisfied, the lower start winning opening 14B is opened. That is, the movable wings 14C and 14C provided in the lower start winning opening 14B are tilted left and right over a predetermined period (for example, 0.5 seconds) by a solenoid (not shown) provided on the back of the game board 11. When the movable wings 14C and 14C fall to the left and right, the game balls can be awarded to the lower start winning opening 14B by being guided by the fallen movable wings 14C and 14C.

  When a game ball wins one of the upper and lower start winning openings 14A, 14B, a sensor provided in each start winning opening 14A, 14B detects the game ball, and based on the detection signal, a predetermined number of winning balls Is paid out to the upper plate 27A. Further, when a game ball wins at each start winning opening 14A, 14B, a right / no-go determination right for determining whether or not to perform “big hit game” is generated, and the determination result is notified to the player by the display device 13. The

  Specifically, three special symbols 13A, 13B, and 13C on the left, middle, and right are normally displayed side by side on the display device 13. Each of these special symbols is composed of, for example, a plurality of types representing numbers “0” to “9”. Usually, a predetermined type of each special symbol 13A, 13B, 13C is stopped. It is displayed. Then, when a game ball wins in either of the start winning ports 14A, 14B, these three special symbols 13A, 13B, 13C are displayed in a variable manner (scrolled up and down), and after a predetermined time, for example, The special symbols 13A, 13B, and 13C are stopped and displayed in the order of left, middle, and right. At this time, for example, when all of the special symbols 13A, 13B, and 13C are the same symbol, that is, when they become doublet, the game shifts from “normal game” to “big hit game”. Further, when only the special symbol to be stopped last is left and the remaining two special symbols are stopped with the same symbol, the game is in the “reach state”.

  Here, while the special symbols 13A, 13B, 13C are variably displayed on the display device 13 or during the “big hit game”, the number of game balls won in each start winning opening 14A, 14B is a predetermined number. When the cumulative number is counted up to the limit (so-called “hold”), and the special symbol 13A, 13B, 13C is stopped and displayed with the symbol combination, or the “big hit game” ends, the special symbol 13A, 13B is again based on the reserved memory. , 13C variation display is started. Note that the number of holds is notified to the player by the number of lights of the LED for the number of holds provided in the game area R1.

  The big prize opening 15 is open to the front of the game board 11 and has a horizontally long shape, and is always closed by the movable door 15T. As described above, when the special symbol is stopped and displayed with a doublet, the movable door 15T falls to the front side and the big winning opening 15 is opened, and the game ball wins the big winning opening 15 with the movable door 15T as a guide. It becomes possible.

  Here, when the movable door 15T is opened and closed, it is referred to as “round”. In one round, the movable door 15T has been opened for 30 seconds or a game is played in the grand prize opening 15. The process ends when any of the end conditions of 10 balls has been won first. Further, the “big hit game” is continued up to, for example, 15 rounds.

  Although not shown in the drawing, a continuous winning opening and a counting winning opening are provided inside the big winning opening 15. When the movable door 15T is opened, the continuous prize opening is open, and when the continuous prize opening is won, the continuous prize opening is closed while the counting prize opening is kept open. When a specific area sensor (not shown) provided in the continuous winning opening detects a winning of a game ball, the next round is continuously executed after the above-described end condition is satisfied and the round ends. When a count sensor (not shown) provided in the counting prize opening detects the winning of a game ball, the winning balls to the big prize opening 15 are counted together with the winning balls to the continuous winning opening, Thus, it is checked whether or not a total of 10 has been reached. Note that when a game ball wins the grand prize opening 15, a predetermined number of game balls that are larger than when winning in the other winning openings 14A, 14B, 20, 21 are paid out to the upper plate 27A.

On the other hand, the locking plate 121 is retracted to the outside of the game board fitting portion 77 at the other end position of the rotatable range, and the locked state with the game board 11 is released.

  A game board fixing mechanism 100 according to the present invention is provided at the opening edge on the lower side of the game board fitting portion 77. As shown in FIG. 10, the game board fixing mechanism 100 is received by a mechanism receiving portion 73 in which a portion near the right end of the lower side of the game board fitting portion 77 is recessed into a deep groove shape. The mechanism receiving portion 73 is a rectangular parallelepiped depressed space having a depth greater than the width and a depth greater than the depth. Further, the mechanism receiving portion 73 has a front surface opening facing the glass door 95 side in addition to the upper surface opening facing the inside of the game board fitting portion 77. The rear end wall 73A opposite to the front opening of the mechanism receiving portion 73 and the retaining wall 77A protruding from the opening edge on the lower side of the game board fitting portion 77 are directed to the rear surface of the inner frame 75. It consists of a part of the same reinforcing sheet metal.

  As shown in FIG. 11, the game board fixing mechanism 100 is configured by assembling a plurality of metal parts to a bracket 101 fixed inside the mechanism receiving portion 73. The bracket 101 is formed by bending a sheet metal into a groove shape in accordance with the depressed shape of the mechanism receiving portion 73. Specifically, a pair of opposing walls 101A, 101A facing in the left-right direction of the pachinko gaming machine 10, a bottom wall 101B connecting the lower ends of the opposing walls 101A, 101A, the opposing walls 101A, 101A and the bottom There are provided mounting wall walls 101C, 101C, 101C that are bent at right angles to the wall 101B. The pair of opposing walls 101 </ b> A and 101 </ b> A are assigned to the pair of left and right opposing surfaces in the mechanism receiving portion 73, and the bottom wall 101 </ b> B is assigned to the bottom surface of the mechanism receiving portion 73. Each mounting rod wall 101C is provided with a screw hole for screwing the bracket 101 to the inside of the mechanism receiving portion 73 (see FIG. 10). Here, the bracket 101 is disposed such that the upper end edges of the opposing walls 101A, 101A are below the pair of left and right lateral opening edges 73B, 73B in the upper surface opening of the mechanism receiving portion 73 (see FIG. 16).

  A guide column 102 stands upright from the center of the bottom wall 101B of the bracket 101. The guide column 102 has a cylindrical shape and is parallel to the opposing walls 101A, 101A and the rear end wall 73A of the mechanism receiving portion 73. The upper end portion of the guide column 102 protrudes from the upper end edge of the opposing walls 101A and 101A and is located below the lateral opening edges 73B and 73B of the mechanism receiving portion 73 (see FIG. 16).

  A coil spring 103 (corresponding to the “biasing member” of the present invention) is loosely fitted on the outside of the guide column 102. Further, a movable plate 104 is fitted on the guide column 102 so as to be movable up and down over the coil spring 103. The movable plate 104 has a structure in which a sheet metal having elasticity is bent at a right angle, and includes a lifting base 108 whose plate thickness direction faces the up-down direction, and a ball push-up portion 109 whose plate thickness direction faces the front-rear direction. Yes.

  The elevating base 108 has a protruding piece structure that is long in the front-rear direction, and a circular hole 108 </ b> A having substantially the same diameter as the guide column 102 is formed through the end close to the ball pusher 109. The guide column 102 passes through the circular hole 108A, and the coil spring 103 is sandwiched between the elevating base 108 and the bottom wall 101B of the bracket 101 in a compressed state. That is, the entire movable plate 104 is constantly biased upward by the elastic force of the coil spring 103. The elevating base 108 protrudes closer to the glass door 95 than the bracket 101 (see FIG. 11A).

  The ball pusher 109 has a protruding piece structure that is narrower than the lifting base 108 and is entirely accommodated inside the mechanism receiving portion 73. Specifically, as shown in FIG. 10 (B), the pair of opposing walls 101A, 101A, 101B are sandwiched between the guide column 102 and the rear end wall 73A of the mechanism receiving portion 73 in the front-rear direction and in the left-right direction. 101A and a pair of concave-shaped portions 111, 111 described below. The upper end portion of the ball pusher 109 faces the upper surface opening of the mechanism receiving portion 73.

  On the upper surface of the elevating base 108, there is provided a retractable locking lever 110 corresponding to the “rotating locking member” of the present invention. The retractable locking lever 110 is formed by bending a sheet metal punched into a predetermined shape. The retractable locking lever 110 has a pair of concave shapes 111 and 111 having the same shape and arranged opposite to each other in the thickness direction, and a rotation operation portion 115 connecting the concave shapes 111 and 111 to each other. is doing. Each of the concave-shaped portions 111 and 111 includes a pair of plate holding portions 112 and 113 capable of holding the lower edge portion of the game board 11 fitted in the game board fitting portion 77 in the thickness direction, and the pair of these And a connecting portion 114 that communicates between the lower end portions of the plate sandwiching portions 112 and 113. Hereinafter, when the game board 11 is sandwiched in the thickness direction, the board holding portion 112 that faces the front surface of the game board 11 is referred to as a “locking protrusion 112”, and the board holding portion 113 that faces the rear surface of the game board 11 is referred to as “locking protrusion 112”. This is referred to as “detachment assist protrusion 113”.

  Among the concave-shaped portions 111 and 111, the upper ends of the locking projections 112 and 112 are connected by a rotation operation unit 115 having a protruding piece structure in which the plate thickness direction is directed in the vertical direction. In other words, each concave shape portion 111, 111 has a plate thickness direction facing the left-right direction of the pachinko gaming machine 10, and the locking projections 112, 112 are perpendicular to both side edges on the rear end side of the rotation operation portion 115. Contacted in a bent state. Further, the rotation operation unit 115 protrudes to the glass door 95 side from the locking projections 112 and 112.

  A game board abutting portion 116 is provided integrally with the rotation operation portion 115. The game board abutting portion 116 has a projecting piece structure that is bent at a right angle downward (toward the connecting portion 114) from the rear edge away from the glass door 95 in the rotation operation portion 115, and is a locking projection. 112 and 112 extend in parallel.

  The retractable locking lever 110 is pivotally supported with respect to the bracket 101 so as to be rotatable. Specifically, the pair of opposing walls 101A and 101A in the bracket 101, the guide column 102, and the connecting portions 114 and 114 in the retractable locking lever 110 penetrate in the left-right direction of the pachinko gaming machine 10. Shaft insertion holes are formed, and each shaft insertion hole has a center of rotation in a state in which the connecting portions 114, 114 of the retractable locking lever 110 are sandwiched between the opposing walls 101A, 101A of the bracket 101. The shaft 105 is inserted (see FIG. 11B). Thereby, the retractable locking lever 110 is rotatable around a rotation axis parallel to the opening edge on the lower side of the game board fitting portion 77.

  Below the retractable locking lever 110, the lifting base 108 and the coil spring 103 are arranged as described above, and the lifting base 108 is pressed against the tilting locking lever 110 by the elastic force of the coil spring 103. Yes. With this configuration, the range in which the retractable locking lever 110 can be rotated is limited, and the pachinko gaming machine 10 can be rotated in the front-rear direction within the rotatable range. Then, the game board 11 is moved to the game board fitting portion 77 at one end position of the rotatable range, specifically, at the rear end position of the rotatable range shown in FIG. 12 (hereinafter referred to as “locking end position”). At the other end position of the rotatable range, specifically, at the front end position (hereinafter referred to as “release end position”) of the rotatable range shown in FIG. The retainer is released so that it can be attached to and detached from the game board fitting portion 77 (see FIG. 16). Here, when the retractable locking lever 110 is positioned at the locking end position, the game board fixing mechanism 100 is in a fixed state, and when the retractable locking lever 110 is positioned at the release end position, the game board is fixed. The mechanism 100 is in a fixed release state.

  In the locking end position shown in FIG. 15, the locking protrusions 112, 112 of the retractable locking lever 110 protrude upward from the upper surface opening of the mechanism receiving portion 73 (the lower side of the game board fitting portion 77). Then, the game board contact portion 116 of the retractable locking lever 110 contacts the front surface of the game board 11 fitted in the game board fitting portion 77. At this time, the rotation operation unit 115 is substantially horizontal, and the tip end portion is in the most retracted position. Further, at the locking end position, the upper edges of the connecting portions 114, 114 in the concave shaped portions 111, 111 are located below the pair of left and right lateral opening edges 73 B, 73 B in the upper surface opening of the mechanism receiving portion 73.

  On the other hand, at the release end position shown in FIG. 16, the locking projections 112 and 112 are inclined forward toward the glass door 95, and the locking projections 112 and 112 and the game board contact section 116 are fitted to the game board. It is located below the lower side of the portion 77. Thereby, the game board 11 can be attached to and detached from the game board fitting portion 77. Moreover, the rotation operation part 115 becomes the inclination attitude | position which descended toward the front-end | tip part, and a front-end | tip part is located in the forefront (glass door 95 side). Further, at the release end position, the separation assisting projections 113, 113 project forward of the retaining wall 77 </ b> A and project upward from the upper surface opening of the mechanism receiving portion 73 (the lower side of the game board fitting portion 77). The upper edges of the connecting portions 114 and 114 are inclined so as to descend from the separation assisting projections 113 and 113 toward the locking projections 112 and 112.

  The separation assisting protrusion 113 includes a curved sliding contact portion 113 </ b> A at an upper end portion away from the connecting portion 114. The curved sliding contact portion 113 </ b> A is curved so as to move away from the locking projection 112 as it moves away from the rotation center shaft 105 (rearward).

  As shown in FIG. 10, longitudinal slits 77S and 77S through which the separation assisting projections 113 and 113 can pass are formed through the rear end wall 73A and the retaining wall 77A of the mechanism receiving portion 73. In the locking end position shown in FIG. 15, the separation assisting projections 113, 113 retract through the slits 77 </ b> S, 77 </ b> S to the rear of the rear end wall 73 </ b> A and the retaining wall 77 </ b> A. Then, in the process of rotating toward the release end position shown in FIG. 16, the separation assisting projections 113 and 113 pass through the slits 77S and 77S and project forward of the rear end wall 73A and the retaining wall 77A.

  When the retractable locking lever 110 rotates between the locking end position and the release end position, the movable plate 104 moves up and down accordingly. Specifically, the lower edge of the connecting portion 114 of the retractable locking lever 110 has an arc portion 114A centered on the rotation shaft (rotation center shaft 105) of the retractable locking lever 110, and an arc. A flat portion 114B continuous with the portion 114A, and a corner portion 114C formed by intersecting the arc portion 114A and the flat portion 114B. Further, the radius of the arc portion 114A is longer than the length of the perpendicular extending from the pivot shaft of the retractable locking lever 110 to the flat portion 114B.

  As shown in FIG. 12A, the flat portion 114B contacts the upper surface of the elevating base 108 at the locking end position, and the retractable locking lever 110 is maintained at the locking end position by the elastic force of the coil spring 103. The Further, as shown in FIG. 13A, at the release end position, the arc portion 114A comes into contact with the upper surface of the elevating base 108, and the retractable locking lever is caused by the friction between them and the elastic force of the coil spring 103. 110 is maintained at the release end position.

  At the locking end position, the entire movable plate 104 is pushed up to the upper end position of the vertical movement stroke, and the amount of elastic deformation of the coil spring 103 is minimized.

  At the locking end position, the upper end portion of the ball pusher 109 is located at substantially the same height as the upper end of the guide column 102. That is, the upper end portion of the ball pushing portion 109 protrudes from the upper end edge of the opposing walls 101A and 101A of the bracket 101 and is positioned below the upper surface opening of the mechanism receiving portion 73 (see FIG. 15). As a result, the upper end portion of the ball pusher 109 is always positioned below the upper surface opening of the mechanism receiving portion 73.

  When the retractable locking lever 110 rotates from the locking end position toward the release end position, the portion that contacts the lifting base 108 changes in the order of the flat portion 114B, the corner portion 114C, and the arc portion 114A. The entire movable plate 104 is gradually pushed down while the portion that contacts the lift base 108 is switched from the flat portion 114B to the arc portion 114A, that is, while the corner portion 114C is in sliding contact with the lift base 108. Along with this, the amount of elastic deformation of the coil spring 103 increases.

  When the circular arc portion 114A is in contact with the elevating base 108, that is, when the retractable locking lever 110 is located at the release end position, the movable plate 104 is pushed down most, and the elastic deformation amount of the coil spring 103 is reduced. Become the maximum.

  At this time, the upper end portion of the ball pushing portion 109 is lower than the guide support column 102, and is substantially at the same position as the upper end edges of the opposing walls 101A and 101A of the bracket 101 (see FIG. 16). At the release end position, only one game ball can stay above the mechanism receiving portion 73, more specifically, between the pair of separation assisting projections 113, 113, the guide column 102, and the retaining wall 77A. A “stasis stop” according to the present invention is formed. It should be noted that the “ball push-up portion” according to the present invention is only required to be provided below the ball retaining portion where the game ball can be retained, and a pair of separation assisting protrusions 113 and 113 and a guide as in the present embodiment. The present invention is not limited to the one disposed below the “sphere retaining portion” formed between the support column 102 and the retaining wall 77A. Furthermore, the “ball retention portion” may be configured so that the game ball can remain as it is without moving from the spot, and does not necessarily have to be configured so that the game ball is fitted therein. Further, in the present embodiment, the ball pushing portion 109 is disposed between the support column 102 and the retaining wall 77A, and the game ball enters deep into the space formed between the support column 102 and the retaining wall 77A ( Is prevented. That is, the ball push-up portion constitutes a game board fixing mechanism or a ball insertion preventing portion that prevents the game ball from being inserted into the mechanism receiving portion.

  Here, the lower edge of the connecting portion 114 in the retractable locking lever 110, the lifting base 108, and the coil spring 103 correspond to the “motion converting mechanism” of the present invention.

  Here, as shown in FIG. 8, the game board 11 is detached from the game board fitting portion 77 and the corner 114 </ b> C of the retractable locking lever 110 is abutted against the elevating base 108, so that the When the hand is released from the type locking lever 110, the retractable type locking lever 110 automatically moves to the locking end position by the elastic force of the coil spring 103. Further, the game board 11 is detached from the game board fitting portion 77 and the arcuate portion 114A of the tiltable locking lever 110 is brought into contact with the elevating base 108 so that the hand can be moved from the tiltable locking lever 110. When the lever is released, the retractable locking lever 110 stops at that position due to the frictional force with the lifting base 108.

  When the retractable locking lever 110 is switched from the release end position to the locking end position, the movable plate 104 is not pushed down, so that the switching can be performed with a relatively small operating force. On the other hand, when switching from the locking end position to the release end position, it is necessary to push down the movable plate 104 against the elastic force of the coil spring 103, so that a relatively large operating force is required. That is, the switch from the release end position to the lock end position is facilitated, and the switch from the lock end position to the release end position does not occur unintentionally.

  A door-side contact member 93 formed by bending a sheet metal is fixed to a portion of the rear surface of the glass door 95 that faces the game board fixing mechanism 100 when the glass door 95 is in the closed position. As shown in FIG. 7A, the door-side contact member 93 is provided integrally with a metal reinforcing plate 94 provided along the lower side of the glass door 95. As shown in FIG. 7 (B), the door-side contact member 93 is bent at a right angle at the upper end of the fixed wall 93E addressed to the metal reinforcing plate and the fixed wall 94E, so that the glass door 95 and the inner frame 75 are bent. A horizontal protruding wall 93A protruding toward the front surface, a tip standing wall 93B standing upright from the tip of the horizontal protruding wall 93A, and a side standing wall standing upright from one side of the horizontal protruding wall 93A in the left-right direction 93C.

  More specifically, the horizontal protruding wall 93 </ b> A has a horizontally long shape that is long in the left-right direction with respect to the front-rear direction of the pachinko gaming machine 10. The tip upright wall 93B is unevenly distributed on one side in the longitudinal direction of the horizontal projecting wall 93A, specifically, on the right side when the glass door 95 is viewed from the back side, and has a horizontally long shape that is short in the vertical direction with respect to the horizontal direction. I am doing. The width in the left-right direction of the tip upright wall 93 </ b> B is larger than the width in the left-right direction of the rotation operation unit 115 in the retractable locking lever 110. In addition, the side standing wall 93C rises from the right side of the horizontal protruding wall 93A when the glass door 95 is viewed from the back side, and is larger than the tip standing wall 93B in the vertical direction.

  The configuration of the pachinko gaming machine 10 of the present embodiment is as described above. Next, the operation of the present embodiment will be described. When attaching the game board 11 to the inner frame 75, first, the glass door 95 is opened. Next, the upper locking member 120 is set to the unlocking position, and the game board fixing mechanism 100 is in the unlocked state. Specifically, the retractable locking lever 110 is on the front side (the front side of the pachinko gaming machine 10). Tilt to the release end position.

  Next, as shown in the change from FIG. 14A to FIG. 14B, the left side of the game board 11 is inserted into the gap between the fixed retaining portions 130, 130 and the retaining wall 77A from an oblique side. Then, after the one side portion is fitted, the right side of the game board 11 is rotated so as to approach the game board fitting portion 77 with the left side of the game board 11 as the central axis. At this time, since the retractable locking lever 110 is at the release end position as shown in FIG. 16, the game board 11 and the locking protrusions 112 and 112 do not interfere with each other.

  When the right side of the game board 11 is rotated so as to approach the game board fitting portion 77, the separation assisting protrusions 113 and 113 come into contact with the rear surface of the game board 11, as shown in FIG. At this time, the entire game board 11 is not in a state of being completely fitted to the game board fitting portion 77 (completely fitted state), and the right side of the game board 11 is still on the front opening side of the game board fitting portion 77. It is the one side part fitting state extruded. Here, the game board 11 is supported by the lower side of the game board fitting part 77 in the one side part fitting state, and is completely from the position where the one side part fitting state is brought about by friction with the game board fitting part 77. It is possible to stop at any position up to the position where the mating state is reached. Therefore, even if the hand is released from the game board 11 after the one side part is fitted, the game board 11 can be held by the inner frame 75 in the one side part fitted state. Further, by locking the lower edge portion of the game board 11 in the fitted state on one side, the retractable locking lever 110 can also be stopped between the start end position and the release end position.

  In order to change the game board 11 from the one-side-fitted state to the fully-fitted state, the game board 11 is pushed into the game board fitting part 77 or is rotated so that the retractable locking lever 110 is raised. Then, the release end position is switched to the locking end position. When the game board 11 is pushed in, the separation assisting protrusions 113 and 113 are pushed by the game board 11 so that the retractable locking lever 110 rotates toward the locking end position. When the game board 11 is completely engaged, the separation assisting projections 113 and 113 are retracted to the rear side of the retaining wall 77A, and the retractable locking lever 110 is in the locking end position, so that the game board The contact portion 116 comes into contact with the front surface of the game board 11 and sandwiches the game board 11 with the retaining wall 77A (state shown in FIG. 15).

  On the other hand, when the retractable locking lever 110 is manually operated and moved to the locking end position, the game board contact portion 116 is engaged with the lower edge of the game board 11 and pushed backward, The entire game board 11 is fitted into the game board fitting portion 77.

  When the game board 11 is completely fitted, the retractable locking lever 110 is maintained at the locking end position by the elastic force of the coil spring 103. Further, since the ball pusher 109 is always located below the upper surface opening of the mechanism receiving portion 73, it does not interfere with the game board 11 and can be smoothly and completely engaged.

  When the game board 11 is in a completely fitted state, in other words, when the retractable locking lever 110 is set to the locking end position, the upper locking member 120 is switched to the locking position. As a result, the fixed retaining portions 130, 130, the game board fixing mechanism 100, and the upper locking member 120 cooperate to prevent the game board 11 from being detached from the game board fitting section 77. In the present embodiment, the upper locking member 120 is provided, but the game board 11 can be prevented from coming off even in a configuration including only the game board fixing mechanism 100 and the fixed retaining portions 130 and 130.

  When the game board 11 is prevented from being detached from the game board fitting portion 77, the glass door 95 is brought into a closed position with respect to the inner frame 75, and the locking pieces 94A and 94A of the glass door 95 and the door locking provided in the inner frame 75 The tools 74 and 74 are locked (the glass door 95 is locked in the closed position). At this time, as shown in the change from FIG. 17 (A) to FIG. 17 (B), the door-side contact member 93 is rotated by the rotation operation portion 115 of the retractable locking lever 110 located at the locking end position. And the movable plate 104, and abut against the front edge portions of the locking projections 112, 112.

  Here, when the glass door 95 is in the closed position, the door-side contact member 93 is disposed below the rotation operation portion 115 of the retractable locking lever 110 and abuts against the locking projections 112 and 112. By doing so, rotation of the retractable locking lever 110 to the release end position can be reliably prohibited. Thereby, the illegal act of switching the retractable locking lever 110 to the release end position while keeping the glass door 95 in the closed position can be prevented. The above is the description of the operation when attaching the game board 11 to the inner frame 75.

  When detaching the game board 11 from the inner frame 75 (game board fitting portion 77), an operation reverse to the case of attachment may be performed. That is, the glass door 95 is opened and the upper locking member 120 is set to the unlocking position, and then the game board fixing mechanism 100 is unlocked, specifically, the retractable locking lever 110 is tilted forward. Thus, the locking end position (state shown in FIG. 15) is switched to the release end position (state shown in FIG. 16).

  When the retractable locking lever 110 is switched from the locking end position to the release end position, the elevating base 108 projecting forward from the bracket 101 and the turning operation portion 115 of the retractable locking lever 110 are fingered. The raising and lowering base 108 is bent upward with the corner portion 114C of the tiltable locking lever 110 as a fulcrum. Then, the retractable locking lever 110 can be rotated forward, and the retractable locking lever 110 rotates to the release end position while pushing down the entire movable plate 104 against the elastic force of the coil spring 103. To do.

  As shown in the change from FIG. 15 to FIG. 16, when the retractable locking lever 110 rotates from the locking end position toward the release end position, the separation assisting protrusions 113 and 113 pass through the slits 77S and 77S. Then, it protrudes to the front side of the retaining wall 77A, hits the rear surface of the game board 11, and pushes the game board 11 to the front opening of the game board fitting portion 77. That is, by releasing the retractable locking lever 110, the right side portion of the game board 11 is pushed out to the front opening side of the game board fitting portion 77, and the one side portion fitting state is changed from the completely fitted state. To change. At this time, since the curved sliding contact portions 113A and 113A of the separation assisting projections 113 and 113 are in sliding contact with the game board 11, the separation assisting projections 113 and 113 and the game board 11 can be pushed out smoothly without being caught. it can.

  When the retractable locking lever 110 is set to the release end position, the right side of the game board 11 that has been fitted into one side part is gripped, and the left side of the game board 11 is centered. The game board 11 is rotated to the near side (front side of the game board fitting portion 77), and further, the game board 11 is horizontally moved diagonally to the right side, so that the space between the fixed retaining portions 130 and 130 and the retaining wall 77A is increased. The left side of the game board 11 is extracted from the gap. As a result, the game board 11 is detached from the inner frame 75.

  Here, when the game board 11 is detached from the inner frame 75 and then the glass door 95 is rotated toward the closed position while the retractable locking lever 110 is in the release end position, the following is performed. Become. That is, as shown in the change from FIG. 18A to FIG. 18B, the door-side contact member 93 is located above the locking projections 112 and 112 without contacting the retractable locking lever 110. , And enters between the locking projections 112, 112 and the separation assisting projections 113, 113. And the glass door 95 will be in a closed position. That is, when the game board 11 is detached from the inner frame 75, the glass door 95 can be brought into the closed position even when the retractable locking lever 110 is at the release end position.

  When the glass door 95 is rotated toward the closed position while the game board 11 is fitted to one side and the retractable locking lever 110 is at the release end position, the following occurs. That is, since the right side portion of the game board 11 is pushed out to the front opening side of the game board fitting portion 77, the door-side contact member 93 hits the game board 11 as shown in FIG. While pushing into the inside of the game board fitting part 77, it is pushed by the game board 11, and the retractable locking lever 110 rotates a little from the release end position. However, since the door-side contact member 93 enters above the locking projections 112 and 112 (in other words, within the rotation region of the locking projections 112 and 112), the door-side contact member 93 and Due to this interference, the retractable locking lever 110, the game board 11, and the glass door 95 all stop moving in the middle. That is, it becomes impossible to set the retractable locking lever 110 to the locked end position, and it becomes impossible to make the game board 11 fully engaged, and the glass door 95 can be set to the closed position. It is forbidden.

  Here, as described above, the game board 11 can be stopped at any position from the position at which the one side portion is fitted to the position at which the game board 11 is completely fitted, so that it engages with the lower edge of the game board 11. By doing so, the retractable locking lever 110 can also be stopped between the locking end position and the release end position.

  Then, although the retractable locking lever 110 is rotated toward the locking end position, the operation is insufficient, and the retractable locking lever 110 is between the release end position and the locking end position. When the glass door 95 is rotated toward the closed position while being stopped (in other words, with the game board 11 in one side fitting state), the retractable locking lever 110 is stopped. Depending on the position, there are a case where the glass door 95 can be closed and a case where the glass door 95 cannot be closed.

  Specifically, as shown in FIG. 20B, the distal end of the rotation operation portion 115 of the retractable locking lever 110 is below the lower end edge 93B1 of the distal end standing wall 93B of the door-side contact member 93. In the process of bringing the glass door 95 close to the closed position, the door-side contact member 93 (specifically, the corner curved portion 93D where the horizontal protruding wall 93A and the tip standing wall 93B intersect) is formed. It strikes against the upper surface of the rotation operation unit 115 and comes into sliding contact therewith. At this time, the retractable locking lever 110 is pushed downward by the corner bending portion 93D and rotates toward the release end position. In this case, even if the glass door 95 is brought close to the closed position, as described above, the game board 11, the retractable locking lever 110, and the door-side contact member 93 interfere with each other. The locking lever 110, the game board 11, and the glass door 95 are all stopped on the way, and the glass door 95 is prohibited from being in the closed position (see FIG. 19).

  On the other hand, as shown in FIG. 20A, the distal end of the rotation operation portion 115 of the retractable locking lever 110 is formed between the lower end edge 93B1 and the upper end edge 93B2 of the front end standing wall 93B of the door side contact member 93. When the glass door 95 is positioned in the middle, the leading-end standing wall 93 </ b> B of the door-side contact member 93 abuts against the distal end of the rotation operation unit 115 when the glass door 95 is brought close to the closed position. Then, as the glass door 95 approaches the closed position, the tip of the rotation operation unit 115 is pushed up while being in sliding contact with the tip upright wall 93B, and the retractable locking lever 110 rotates toward the locking end position. . Further, when the distal end of the rotation operation portion 115 moves upward from the upper end edge 93B2 of the distal end standing wall 93B, the distal end standing wall 93B comes into contact with the locking projections 112 and 112 (see FIG. 17A). Then, when the locking projections 112 and 112 are pushed by the door-side contact member 93, the retractable locking lever 110 is set to the locking end position. Thereby, the glass door 95 will be in a closed position.

  Although not shown, even when the distal end of the rotation operation portion 115 of the retractable locking lever 110 is positioned above the upper end edge 93B2 of the distal end standing wall 93B of the door-side contact member 93 from the beginning, By rotating the glass door 95 toward the closed position, the locking projections 112, 112 are pushed by the door-side contact member 93, and the retractable locking lever 110 is moved to the locking end position to thereby move the glass. The door 95 can be in the closed position.

  The operation of attaching / detaching the game board 11 to / from the inner frame 75 has been described above. Here, for example, when the game board 11 is detached from the inner frame 75 with the retractable locking lever 110 at the release end position, The game ball Q1 remaining on the board 11 (or the back mechanism board 52) spills down, and as shown in FIGS. 21 (A), 23 (A) and 25 (A), a pair of separation assist projections 113. , 113, the guide strut 102, and the retaining wall 77A, the game ball Q1 may stay in the ball retaining portion (stay on the spot).

  In this state, it is impossible to hold the lower edge of the game board 11 between the retractable locking lever 110 (specifically, between the locking projection 112 and the separation assisting projection 113), and the game It becomes impossible to bring the plate 11 into the completely fitted state (the state shown in FIG. 15) with the game board fitting portion 77. Even if it can be in a completely fitted state, it is not preferable to leave the game ball Q1 in the ball retaining portion because it may cause the pachinko gaming machine 10 to malfunction.

  On the other hand, in the pachinko gaming machine 10 of the present embodiment, the game ball Q1 staying in the ball staying portion can be easily taken out by performing the following operation. Specifically, the retractable locking lever 110 is returned from the release end position to the locking end position. Then, as shown in FIG. 23B, the entire movable plate 104 moves upward, and the ball push-up portion 109 pushes up the game ball Q1 retained in the ball retention portion. In some cases, the pushed up game ball Q1 is flipped up. Thus, at least a part of the game ball Q1 is pushed out of the game board fixing mechanism 100.

  Specifically, when the retractable locking lever 110 is in the locking end position, the upper end portion of the ball pushing portion 109 protrudes from the upper edge of the connecting portion 114 of the concave shape portions 111 and 111, and from FIG. As shown in the diagram (C) (or FIG. 25 (B) to the diagram (C)), the game ball Q1 moves to either the left or right, and the left and right 1 at the upper surface opening of the mechanism receiving portion 73. It is supported between one of the pair of lateral opening edges 73B and 73B and the upper end edge of the ball pusher 109. At this time, since the game ball Q1 is lifted upward from the release end position and is closer to the left and right sides of the mechanism receiving portion 73, it becomes easy to touch and pick the game ball Q1 with fingers. The operation of removing the game ball Q1 from the ball retention portion is facilitated. Here, in a state (the state shown in FIG. 25C) where the ball push-up portion 109 pushes up the game ball Q1, and the game ball Q1 is supported between the lateral opening edge 73B and the upper end edge of the ball push-up portion 109. A part of the game ball Q1 is pushed out and exposed above and to the side of the game board fixing mechanism 100.

  In addition, when the game ball Q1 is bounced up by the ball pusher 109, the game ball Q1 may be excluded to the side of the mechanism receiving portion 73 as it is. In this case, it is not necessary to remove the game ball Q1 with fingers. Note that the game ball Q1 excluded to the side of the mechanism receiving portion 73 may pass through the front side of the inner frame 75 and enter the lower plate 27B.

  In addition, the game ball Q1 may be excluded from the ball retention portion by performing the following operation following the above operation. That is, when the retractable locking lever 110 is rotated again toward the release end position, the change from FIG. 21 (C) to FIG. 22 (B) and FIG. 23 (C) to FIG. As shown in the change to B) and the change from FIG. 25 (C) to FIG. 26 (B), the game ball Q1 is pushed by the connecting portion 114 in the concave shape portions 111 and 111, and the lateral opening edge 73B Along the side of the guide column 102 and moves between the guide column 102 and the game board contact portion 116 in the forward leaning posture. At this time, the connecting portion 114 and the lateral opening edge 73 </ b> B constitute a ball flow path for the game ball to move between the guide column 102 and the game board contact portion 116.

  In order to remove the game ball Q1 that has moved between the guide column 102 and the game board contact portion 116, it may be scraped with a finger. At this time, the game ball Q1 is compared with the state where the game ball Q1 is supported between the ball pushing portion 109 and the lateral opening edge 73B (the states shown in FIGS. 21B, 23B, and 25B). Can be easily removed. The reason is that the game ball Q1 is located on the front side of the guide column 102, so that the fingers are easy to reach and the distance between the guide column 102 and the game board contact portion 116 is relatively wide, so that the fingers are easy to move. .

  For example, when the retractable locking lever 110 is rotated toward the locking end position in a state where the game ball Q1 is inserted between the guide column 102 and the game board contact portion 116, The game ball Q1 is pushed by the game board abutting portion 116, passes through the side of the guide column 102 (the “ball channel”), and is shown in FIGS. 21 (C), 23 (C), and 25 (C). As described above, the mechanism is held between the lateral opening edge 73 </ b> B in the upper surface opening of the mechanism receiving portion 73 and the game board fixing mechanism 100.

  Thus, according to the pachinko gaming machine 10 of the present embodiment, the ball pusher 109 is raised in conjunction with the operation in which the retractable locking lever 110 rotates from the release end position to the lock end position, Since the game ball staying above the mechanism receiving portion 73 is pushed upward, the game ball can be easily removed.

  Further, by changing the retractable locking lever 110 from the release end position to the lock end position and again changing to the release end position, the game ball staying on the ball pusher 109 side from the guide column 102 is guided to the guide It can be moved to a position that is easier to remove than between the column 102 and the game board contact portion 116, and the game ball can be removed at this position.

  Further, in a state where the game board 11 is detached, the retractable locking lever 110 at an arbitrary rotation position can be moved to the locking end position by the elastic force of the coil spring 103. Further, due to the elastic force of the coil spring 103, the ball push-up portion 109 can be raised in the mechanism receiving portion 73 when the retractable locking lever 110 rotates toward the locking end position. In other words, the single retractable latch lever 110 and the ball pusher 109 can be urged by one coil spring 103, so that the parts can be shared.

  Further, by turning the retractable locking lever 110 from the locking end position to the release end position, the separation assisting projections 113 and 113 are connected to the gaming board 11 in the completely fitted state. Since it can be pushed out from 77 and brought into a one-side part fitting state, it becomes possible to easily take out the game board 11 from the game board fitting part 77.
