When this is done, the door-side pressing member pushes the rotation locking member and rotates it toward the locking end position, thereby bringing the game board locking mechanism into the locked state. When the game board locking mechanism is locked, the open / close door can be set to the closed position. That is, even if the rotation locking member is shifted from the locking end position, the position of the rotation locking member can be corrected in the process of moving the opening / closing door to the closing position, and the opening / closing door is closed. It becomes possible to. Therefore, the trouble of directly operating the rotation locking member to move it to the locking end position can be saved, and the assembling work can be performed more smoothly than before. Here, the technical scope of the present invention includes not only a configuration in which the door-side pressing member abuts against the rotation locking member but also a configuration in which the door-side pressing member does not abut on the rotation locking member. In addition, a configuration in which the rotational locking member is indirectly pushed without being included "is also included. That is, the door-side pressing member abuts against another member different from the rotation locking member such as a game board and pushes the rotation locking member indirectly through the other member. You may make it push to the position side. Further, the other member that comes into contact with the door-side pressing member may be provided on the game board side, or may be provided on the game board housing frame side.

[Invention of claim 2]
According to the invention of claim 2, the interlocking locking boundary position is set between the locking end position and the release end position, and the rotation locking member is located between the interlocking locking boundary position and the locking end position. When the open / close door is rotated toward the closed position in the disposed state, the door-side pressing member pushes the rotation locking member and rotates it toward the locking end position, thereby engaging the game board locking mechanism. Turn off. On the other hand, when the opening / closing door is rotated toward the closed position in a state where the rotation locking member is disposed closer to the release end position than the interlocking locking boundary position, the door-side pressing member causes the rotation locking member to move. Even if pressed, the rotation locking member does not rotate to the locking end position side.

  Here, if the interlocking locking boundary position is not set, that is, when the opening / closing door is rotated toward the closed position, the door-side pressing member pushes the rotating locking member from the release end position. When configured to rotate to the locking end position, the interlocking locking boundary position in the present invention may be set to the “release end position”, but in this case, the rotation of the rotation locking member The possible range is narrow compared to the configuration of the present invention. Therefore, the rotation locking member set to the release end position becomes an obstacle when the game board is attached and detached, and there is a possibility that smooth work is hindered.

  On the other hand, in the present invention, since the interlocking lock boundary position is set between the lock end position and the release end position, the rotation is performed as compared with the case where the interlock lock boundary position is not set as described above. The rotatable range of the locking member can be widened. Therefore, if the rotation locking member is set at the release end position, the rotation locking member does not become an obstacle when the game board is attached / detached, and the game board can be attached / detached smoothly.

[Invention of claim 3]
According to the invention according to claim 3 configured as described above, the rotation locking member is disposed between the predetermined position between the locking end position and the release end position and the locking end position. When the opening / closing door is rotated toward the closed position, the door-side pressing member pushes the game board or the rotation locking member to rotate it toward the locking end position. In other words, even if the rotation locking member is shifted from the locking end position, if the shift is within a predetermined range, the position of the rotation locking member is changed in the process of moving the open / close door to the closed position. It can be modified and the door can be in the closed position. Therefore, the trouble of directly operating the rotation locking member to move it to the locking end position can be saved, and the assembling work can be performed more smoothly than before.

  Here, if the “predetermined position” is not set between the lock end position and the release end position, that is, when the open / close door is rotated toward the closed position, the door-side pressing member is moved to the game board. Alternatively, in the case where the rotation locking member is pushed to rotate from the release end position to the lock end position, the “predetermined position” may be set to the “release end position”. The pivotable range of the pivot locking member is narrower than that of the configuration of the present invention. Therefore, the rotation locking member set to the release end position becomes an obstacle when the game board is attached and detached, and there is a possibility that smooth work is hindered.

  On the other hand, in the present invention, since the “predetermined position” is set between the locking end position and the release end position, the rotation locking member is more effective than the case where the “predetermined position” is not set as described above. Can be widened. Therefore, if the rotation locking member is set at the release end position, the rotation locking member does not become an obstacle when the game board is attached / detached, and the game board can be attached / detached smoothly.

[Invention of claim 4]
According to the invention of claim 4, in the state in which the rotation locking member is disposed at the release end position, the movement of the open / close door to the closed position is prohibited by interference with the game board. It is possible to prevent the opening / closing door from being closed while the retaining due to is incomplete. In contrast, if the game board is detached from the game board housing frame, the open / close door can be set to the closed position regardless of the position of the rotation locking member. That is, when the opening / closing door is brought into the closed position with the game board detached from the game board housing frame, the useless operation of returning the rotation locking member to the locking end position can be omitted.

[Invention of claim 5]
According to the fifth aspect of the present invention, in a state where the game board is detached from the game board housing frame, the free rotation of the rotation locking member is limited, and the one end position or the other end position ( It can be stopped at either the locking end position or the release end position.

[Invention of claim 6]
According to the sixth aspect of the present invention, when the rotation locking member is rotated from the locking end position to the release end position, the separation assisting protrusion pushes the game board from the side opposite to the main plane to fit the game board. Since it pushes out from a joint part, it becomes possible to take out the game board from the inside of a game board fitting part easily.

[Invention of Claim 7]
According to the invention of claim 7, when the game board is fitted into the game board fitting part, the fixed retaining part provided on one side part near the rotation center of the opening / closing door among the game board fitting parts. One side of the game board is inserted from the oblique side into the one side part, and then the game board is rotated about the one side. When the game board is rotated, the separation assisting protrusion is pushed by the game board, and the rotation locking member moves to the locking end position. That is, the rotation locking member can be rotated to the locking end position by changing the game board from the one side fitting state to the complete fitting state.

  Further, when the game board is detached from the game board fitting portion, the rotation locking member is rotated from the locking end position to the release end position. Then, the separation assisting projection pushes the game board from the game board fitting part, and changes from the completely fitted state to the one side fitted state.

[Invention of Claim 8]
According to the eighth aspect of the present invention, when the hand is released from the game board after the one side part is fitted, the game board can be held in the game board housing frame with the one side part fitted. .

[Invention of claim 9]

In addition, the game board and the rotation locking member that are fitted to one side are locked, so that the rotation locking member can be stopped at an intermediate position between the locking end position and the release end position. .

[Invention of Claim 10]
According to the invention of claim 10, it is possible to prevent an illegal act of switching the rotation locking member to the release end position while keeping the opening / closing door in the closed position. Further, for example, even when the gaming machine is tilted and a force is applied to the rotation locking member from the game board, the rotation locking member can be prevented from reaching the release end position.

[Invention of Claim 11]
According to the invention of claim 11, since the rotation locking member is formed by bending a sheet metal, it is possible to reduce the weight while securing the strength of the rotation locking member.

[Invention of Claim 12]
According to the invention of claim 12, the movable plate is pressed against the rotation locking member from below by the elastic force of the coil spring compressed between the movable plate and the bottom of the groove-shaped base portion. As the rotation locking member rotates, the contact position of the rotation locking member with respect to the movable plate changes, so that the movable plate moves up and down against the spring force of the coil spring. Specifically, the flat portion contacts the movable plate at the locking end position. At this time, the movable plate is pushed up most and the elasticity of the coil spring is minimized. In the process of rotating from the locking end position toward the release end position, that is, in the process of cornering against the movable plate and in sliding contact with the movable plate, the movable plate is pushed down, and the elastic force of the coil spring gradually increases. Increase. And when a contact part with a movable plate switches from a corner | angular part to a circular arc part, a movable plate will be pushed down most and the elasticity of a coil spring will become the maximum. Thereafter, the arc portion comes into sliding contact with the movable plate until the release end position is reached, and the spring force of the coil spring is maintained at the maximum.

  Here, when the rotation locking member is switched from the release end position to the locking end position, the movable plate is not pushed downward, so that it can be switched to the locking end position 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 against the spring force of the coil spring, so that a relatively large operating force is required. That is, it is possible to prevent the switching from the locking end position to the releasing end position unintentionally while facilitating switching from the releasing end position to the locking end position.

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.

  The retractable locking lever 110 includes a pressing piece 116. The pressing piece 116 is bent downward at a right angle from a rear end edge away from the glass door 95 in the rotation operation portion 115, and extends in parallel with the locking projections 112 and 112.

  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 support column 102, and the connecting portions 114 and 114 in the retractable locking lever 110 penetrated in the left-right direction of the pachinko gaming machine 10. A shaft insertion hole is formed, and each connecting portion 114, 114 of the tiltable locking lever 110 is sandwiched between the opposing walls 101A, 101A of the bracket 101. 105 is inserted (see FIG. 11B). Thereby, the retractable locking lever 110 can be rotated around a rotation axis that is horizontal and parallel to the opening edge on the lower side of the game board fitting portion 77. In other words, the retractable locking lever 110 can be rotated in the front-rear direction of the pachinko gaming machine 10.

  The range in which the retractable locking lever 110 can be rotated by the lock plate 104 pressed from below by the elastic force of the coil spring 103 is limited, and can be reciprocated within the rotatable range. Yes. Then, one end position of the rotatable range, specifically, the rear end position of the rotatable range shown in FIGS. 12 (A) and 12 (B) (hereinafter referred to as “locking end position”) and its vicinity. At this position, the game board 11 is prevented from being detached from the game board fitting portion 77 (see FIG. 15), and the other end position of the rotatable range, specifically, shown in FIGS. 13 (A) and 13 (B). At the front end position (hereinafter referred to as “release end position”) of the rotatable range and the position in the vicinity thereof, the retaining of the game board 11 is released, and the game board fitting portion 77 can be attached and detached (see FIG. 16). The game board locking mechanism 100 is “locked” when the retractable locking lever 110 is positioned at the locking end position, and “locked” when the retractable locking lever 110 is positioned at the release end position. "Release state". Here, the distal end portion of the rotation operation piece 115 moves forward (to the glass door 95 side) from the locking end position toward the release end position.

  Specifically, at the locking end position shown in FIG. 15, the locking protrusions 112, 112 of the retractable locking lever 110 protrude from the upper surface opening of the mechanism receiving portion 73. That is, the locking protrusions 112, 112 protrude upward from the lower side of the game board fitting portion 77, and the pressing piece 116 is locked to the front surface of the game board 11 fitted in the game board fitting portion 77. 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 pressing piece 116 are opened on the upper surface of the mechanism receiving portion 73. Fall into a lower position. Thereby, the game board 11 can be attached and detached from the opening on the front side of the inner frame 75 in the game board fitting portion 77.

  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).

  Further, as shown in FIG. 10, the retaining wall 77A is formed with slits 77S and 77S through which the separation assisting projections 113 and 113 can pass, and the separation assisting projections 113 and 113 are shown in FIG. It retracts to the rear side of the retaining wall 77A at the locking end position, and protrudes to the front side of the retaining wall 77A at the release end position shown in FIG.

  When the retractable locking lever 110 rotates between the locking end position and the release end position, the lock plate 104 moves up and down accordingly. Specifically, the lower edge portion 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 A flat portion 114B continuous with the circular arc portion 114A and a corner portion 114C formed by intersecting the circular arc portion 114A and the flat portion 114B are provided. 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 lock plate 104 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 contacts the upper surface of the lock plate 104, and the retractable locking lever 110 is maintained at the release end position by the elastic force of the coil spring 103. Is done.

  When the retractable locking lever 110 rotates from the locking end position toward the release end position, the portion that comes into contact with the lock plate 104 changes in the order of the flat portion 114B, the corner portion 114C, and the arc portion 114A. The lock plate 104 is gradually pushed down while the portion in contact with the lock plate 104 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 lock plate 104.

  Specifically, when the flat portion 114B is in contact with the lock plate 104, the lock plate 104 is pushed up to the highest position, and the amount of elastic deformation of the coil spring 103 is minimized. When the corner portion 114 </ b> C is in sliding contact with the upper surface of the lock plate 104 while moving to the release end position, the lock plate 104 is gradually pushed down and the amount of elastic deformation of the coil spring 103 increases. When the arc portion 114 </ b> A comes into sliding contact with the lock plate 104, the lock plate 104 is pushed down most and the amount of elastic deformation of the coil spring 103 is maximized. That is, the amount of elastic deformation of the coil spring 103 increases from the locking end position toward the intermediate position of the rotatable range, and the amount of elastic deformation of the coil spring 103 is maximum between the intermediate position of the rotatable range and the release end position. Maintained.

  Here, as shown in FIG. 8, in a state where the game board 11 is detached from the game board fitting portion 77, the tiltable locking lever 110 is brought into contact with the corner portion 114C and the lock plate 104. When the hand is released, the retractable locking lever 110 does not maintain its position and automatically moves to the locking end position by the elastic force of the coil spring 103. Also, when the retractable locking lever 110 is released with the arc portion 114A and the lock plate 104 in contact with each other on the locking end position side from the release end position, the retractable locking lever 110 rotates. It does not move and stops at the same position (intermediate position between the lock end position and the release end position). It should be noted that when the retractable locking lever 110 is moved to an arbitrary rotational position and is released, the retractable locking lever 110 always moves to either the locked end position or the released end position. It may be configured.

  When the retractable locking lever 110 is switched from the release end position to the locking end position, the lock 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 lock 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 pressing 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 plate locking mechanism 100 when the glass door 95 is in the closed position. As shown in FIG. 7A, the door-side pressing member 93 is provided integrally with a metal reinforcing plate 94 provided along the lower side of the glass door 95.

  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 protruding wall 93A, specifically, the right side when the glass door 95 is viewed from the back side, and the vertical direction is shorter than the horizontal direction. It has a horizontally long shape. 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. Thereby, it is possible to easily bring the tip upright wall 93 </ b> B into contact with the retractable locking lever 110. Further, 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. In addition, the height (length in the vertical direction) of the tip standing wall 93B and the protruding amount of the horizontal protruding wall 93A cause the door-side pressing member 93 to contact the game board 11 when the glass door 95 is moved in the closing direction. Or prohibiting by contacting with the retractable locking lever 110, or by prohibiting by contacting with the door-side pressing member 93 when the game board 11 is not attached. It is set as appropriate according to the desired situation.

  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 brought into the unlocking position, and the game board locking mechanism 100 is in the unlocked state. Specifically, the retractable locking lever 110 is moved forward to the unlocking 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 state shown in FIG. 14A), the right side of the game board 11 is brought closer to the game board fitting portion 77 with the left side of the game board 11 as the central axis. Rotate. At this time, since the retractable locking lever 110 is in the release end position as shown in FIG. 16, the game board 11 and the locking projections 112 and 112 do not interfere with each other. The right side can be fitted into the game board fitting portion 77.

  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, and the pressing piece 116 Is brought into contact with the front surface of the game board 11 and the game board 11 is sandwiched between the retaining wall 77A (the 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 pressing piece 116 engages with the lower edge of the game board 11 and pushes it backward, so that the game board 11 Is entirely 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.

  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. Thereby, the fixed retaining portions 130, 130, the game board locking 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. However, the gaming board 11 can be prevented from coming off even in a configuration including only the game board locking 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 pressing member 93 is connected to the rotation operation portion 115 of the retractable locking lever 110 located at the locking end position. It enters between the lock plate 104 and abuts against the front edges of the locking projections 112, 112. Accordingly, the retractable locking lever 110 can be reliably moved to the locking end position, but the door-side pressing member 93 does not necessarily have to abut against the locking protrusion 112.

  Here, when the glass door 95 is set to the closed position, the door-side pressing member 93 is disposed below the rotation operation portion 115 of the retractable locking lever 110 and hits the locking protrusions 112, 112. By doing so, it is possible to reliably prohibit the rotation of the retractable locking lever 110 toward the release end position. 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 operation for 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 to bring the upper locking member 120 into the unlocking position, and then the game board locking mechanism 100 is unlocked, specifically, the retractable locking lever 110 is moved to the front side. Then, the locking end position (state shown in FIG. 15) is switched to the release end position (state shown in FIG. 16).

  When switching the retractable locking lever 110 to the release end position, hold the lock plate 104 projecting forward from the bracket 101 and the rotation operating portion 115 of the retractable locking lever 110 with a finger. The lock plate 104 is warped upward with the corner portion 114 </ b> C of the tilting 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 lock plate 104 against the resilient force of the coil spring 103.

  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.

  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 pressing member 93 is located above the locking projections 112 and 112 without contacting the retractable locking lever 110. It passes 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 pressing member 93 hits the game board 11 as shown in FIG. While pushing into the back of the board fitting part 77, it is pushed by the game board 11, and the retractable locking lever 110 rotates a little from a cancellation | release end position. However, since the door-side pressing 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 pressing member 93 interferes with the door-side pressing member 93. As a result, the retractable locking lever 110, the game board 11, and the glass door 95 all stop moving. That is, the retractable locking lever 110 cannot move further from the position near the release end position to the locking end position, and the game board 11 cannot be brought into a completely fitted state, and the glass door It is also prohibited to set 95 to the closed position.

  Here, as described above, the game board 11 can be stopped at any position between the position at which the one side portion is fitted and the position at which it is completely fitted. By engaging, the retractable locking lever 110 can also be stopped at an arbitrary position between the locking end position and the release end position. The state of the retractable locking lever 110 at this time corresponds to the “rotation stopped state” of the present invention.

  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 moved 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 pressing member 93. If it is, the door-side pressing member 93 (specifically, the corner curved portion 93D where the horizontal protruding wall 93A and the tip standing wall 93B intersect) rotates in the process of bringing the glass door 95 close to the closed position. It strikes against the upper surface of the 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 pressing member 93 interfere with each other. The stop lever 110, the game board 11, and the glass door 95 cannot move any more, 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 between the lower end edge 93B1 and the upper end edge 93B2 of the distal end standing wall 93B of the door-side pressing member 93. When the glass door 95 is brought close to the closed position, the leading end standing wall 93 </ b> B of the door side pressing member 93 hits the leading end of the rotation operation unit 115. 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 tip of the rotation operation unit 115 moves upward from the upper end edge 93B2 of the tip standing wall 93B and the retractable locking lever 110 is in the vicinity of the locking end position, the tip standing wall 93B is locked. Abuts against the protrusions 112, 112. Then, when the locking protrusions 112 and 112 are pushed by the door-side pressing member 93, the retractable locking lever 110 becomes the locking end position. Thereby, the glass door 95 will be in a closed position.

  Although not shown, the tip of the rotation operation portion 115 of the retractable locking lever 110 is positioned above the upper end edge 93B2 of the front end standing wall 93B of the door-side pressing member 93 from the beginning (the retractable locking lever). When the lever 110 is positioned in the vicinity of the locking end position), the locking protrusions 112 and 112 are pushed by the door-side pressing member 93 by rotating the glass door 95 toward the closed position, The retractable locking lever 110 can be moved to the locking end position to place the glass door 95 in the closed position.

  Here, a limit position where the retractable locking lever 110 can be rotated toward the locking end position by contact with the door-side pressing member 93, specifically, FIG. 20 (A). Like the rotation operation unit 115 indicated by the one-dot chain line, the front end of the rotation operation unit 115 is possible when it is exactly the same height as the lower end edge 93B1 of the front end standing wall 93B of the door-side pressing member 93. The rotation position of the tilting locking lever 110 corresponds to the “interlocking locking boundary position” and “predetermined position” of the present invention.

  The above operation is summarized as follows. First, in a state where the game board 11 is detached from the inner frame 75, the glass door 95 is moved to the closed position regardless of whether the retractable locking lever 110 is in the locking end position or the releasing end position. Is acceptable.

  When the game board 11 is completely engaged with the game board fitting portion 77, the retractable locking lever 110 is positioned at the locking end position, and when the glass door 95 is brought close to the closed position in this state, the door The side pressing member 93 enters between the rotation operation unit 115 and the lock plate 104. Also at this time, the movement of the glass door 95 to the closed position is allowed.

  When the game board 11 is in one side fitting state, the retractable locking lever 110 engages with the lower edge of the game board 11 so that an arbitrary position between the locking end position and the release end position is obtained. Stop at the position. When the stop position is between the locking end position and the interlocking locking boundary position, the door-side pressing member 93 moves the retractable locking lever 110 to the locking end by bringing the glass door 95 close to the closed position. Turn to the position side. Therefore, the movement of the glass door 95 to the closed position is allowed.

  On the other hand, when the stop position of the retractable locking lever 110 is closer to the release end position than the interlocking locking boundary position, the door side pressing member 93 is retractable by moving the glass door 95 closer to the closed position. Abutting on the stop lever 110, the pivoting of the retractable locking lever 110 to the locking end position side is prohibited. Specifically, the door-side pressing member 93 rotates the retractable locking lever 110 to the release end position side. The game board 11, the retractable locking lever 110, and the door-side pressing member 93 interfere with each other, so that the retractable locking lever 110 cannot move further from the position near the release end position to the lock end position. Therefore, the movement of the glass door 95 to the closed position is prohibited (see FIG. 19).

  Thus, according to the gaming machine of the present embodiment, even if the retractable locking lever 110 is not at the complete locking end position and is shifted from the locking end position, the shift is within a predetermined range. For example, in the process of moving the glass door 95 to the closed position, the door-side pressing member 93 can correct the position of the retractable locking lever 110 to the locking end position, and the glass door 95 can be set to the closed position. That is, the glass door 95 can be brought into the closed position not only when the retractable locking lever 110 is positioned at the locking end position but also when it is positioned between the locking end position and the interlocking locking boundary position. it can. Therefore, assembly work can be performed more smoothly than before.

  Here, if the interlocking locking boundary position is not provided, that is, when the glass door 95 is brought close to the closed position, the retractable locking lever 110 rotates from the release end position to the locking end position. In order to configure as described above, the interlocking locking boundary position in the present embodiment may be set to the “release end position”. That is, the rotatable range of the retractable locking lever 110 may be narrower than the configuration of the present embodiment. However, if the rotatable range is narrowed, the retractable locking lever 110 becomes an obstacle when the game board 11 is attached to and detached from the front opening of the game board fitting portion 77, and there is a possibility that smooth work is hindered.

  On the other hand, in the present embodiment, since the interlocking locking boundary position is set between the locking end position and the releasing end position, it is more inclinable than the case where the interlocking locking boundary position is not set as described above. The pivotable range of the type locking lever 110 can be widened. Therefore, if the retractable locking lever 110 is set to the release end position, the retractable locking lever 110 does not become an obstacle when the game board 11 is attached / detached, and the game board 11 can be attached / detached smoothly. it can.

  Further, when the glass door 95 is brought close to the closed position in the state where the one side portion is fitted and the retractable locking lever 110 is disposed at the release end position, the game board 11 and the door side pressing member 93 Since the movement of the glass door 95 to the closed position is prohibited by mutual interference with the retractable locking lever 110, the glass door 95 remains incompletely preventing the game board 11 from being detached by the retractable locking lever 110. Can be prevented from being closed. On the other hand, if the game board 11 is detached from the inner frame 75, the glass door 95 can be brought into the closed position regardless of the rotation position of the retractable locking lever 110, and the game board 11 is When the glass door 95 is set to the closed position in a state where it is detached from the inner frame 75, a wasteful operation of returning the retractable locking lever 110 to the locking end position can be omitted. This also eliminates the need to move the retractable locking lever 110 from the locking end position to the release end position when mounting the game board 11, thereby improving the workability of mounting the game board 11.

  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.

[Other Embodiments]
The present invention is not limited to the above-described embodiment. For example, the embodiments described below are also included in the technical scope of the present invention, and various other than the following can be made without departing from the scope of the invention. It can be changed and implemented.

  (1) While the present invention has been applied to the pachinko gaming machine of the above embodiment, a coin gaming machine or slot can be used as long as the gaming board 11 is fitted into the gaming board housing frame (inner frame 75) to prevent it from coming off. The present invention may be applied to a machine or the like.

  (2) In the above embodiment, the front side of the inner frame 75 is provided with the glass door 95 as the “rotating door” according to the present invention, and the game board is inserted into the game board fitting portion 77 from the opening on the front side of the inner frame 75. However, the game board 11 may be configured to be detachable from the rear surface side of the inner frame 75 by providing a “rotating door” on the rear surface side of the inner frame 75.

  (3) In the above embodiment, the game board locking mechanism 100 is provided on the lower side of the game board fitting part 77, but the upper side of the game board fitting part 77, the position where the upper locking member 120 is provided, and the game A game board locking mechanism 100 may be provided on the right side of the board fitting portion 77. Moreover, you may provide not only one but multiple.

  (4) In the above embodiment, the separation assisting protrusions 113 and 113 are formed on the retractable locking lever 110, but the separation assisting protrusion may not be provided.

  (5) In the above embodiment, in the state where the game board 11 is detached from the inner frame 75, the glass door 95 can be used regardless of whether the retractable locking lever 110 is in the locking end position or the releasing end position. However, when the retractable locking lever 110 is at the release end position as shown in FIG. 21C, the glass door 95 is allowed to move to the closed position (see FIG. 18). The movement to the closed position may be prohibited regardless of the presence or absence of the game board 11. Specifically, when the glass door 95 rotates to the closed position with the retractable locking lever 110 in the release end position, the door-side pressing member 93 (specifically, the corner bending portion 93D) rotates. What is necessary is just to arrange | position so that the dynamic operation part 115 may be contact | abutted. In this case, the range that can be corrected to the locking end position by contact with the door-side pressing member is widened compared to the configuration of the above embodiment. Further, as shown in FIG. 21B, in the rotation position where the arc portion 114A is in contact with the lock plate 104, the retractable locking lever 110 can be moved even if the locking retractable locking lever 110 is released. Does not move to any end side of the locking end position and the release end position, but is held at that position (intermediate position between the locking end position and the release end position). The interlocking locking boundary position may be set in a range in which this position can be held (a range in which the arc portion 114A and the lock plate 104 can contact each other). When a force toward the locking end position is applied to the retractable locking lever 110 shown in FIG. 5B, the contact between the retractable locking lever 110 and the lock plate 104 is changed. When the arc portion 114A moves to the corner portion 114C and the contact point becomes the corner portion 114C, it becomes difficult to maintain the posture of the retractable locking lever 110, and it moves to the locking end position.

  (6) In the above-described embodiment, the front-end standing wall 93B of the door-side pressing member 93 is erected at a right angle with respect to the horizontal plane, but may be inclined so as to fall down toward the rear surface side of the glass door 95 toward the upper edge. Good. In this manner, when the distal end of the rotation operation unit 115 comes into contact with the distal end standing wall 93B, the retractable locking lever 110 can be rotated more smoothly toward the locking end position. Become.

  (7) In the above embodiment, a vertical wall is erected from the rear edge of the lock plate 104, and the vertical wall is disposed in a space surrounded by the column 102, the retaining wall 77A, and the U-shaped portions 111, 111. However, it may be configured to prevent the game ball from entering the space.

  (8) In the above embodiment, the slidability with the door-side pressing member 93 may be improved by covering the tip side portion of the rotation operation unit 115 with a resin having a small frictional resistance.

  (9) In the above embodiment, the pair of U-shaped portions 111, 111 are connected by the rotation operation unit 115 to form the retractable locking lever 110. The rotation operation unit 115 may be integrally provided as a tiltable locking lever.

  (10) In the above embodiment, when the glass door 95 is rotated toward the closed position in a state where the retractable locking lever 110 is disposed on the release end position side from the interlocking locking boundary position, it is retractable. The type locking lever 110 is configured to contact the door side pressing member 93 and rotate to the release end position side, but may be any configuration that can prohibit rotation to the locking end position side, For example, when the glass door 95 is rotated toward the closed position in a state where the retractable locking lever 110 is disposed closer to the release end position than the interlocking locking boundary position, the retractable locking lever 110 is The door-side pressing member 93 may be brought into contact with the door-side pressing member 93 so that it cannot be turned to any end side of the rotatable range.

  (11) In the above embodiment, when the glass door 95 is rotated toward the closed position while the retractable locking lever 110 is disposed on the release end position side from the interlocking locking boundary position, the door side Although the pushable member 93 is configured to abut on and push the retractable locking lever 110 to rotate the retractable locking lever 110 toward the locked end position, the door side pressing member 93 is configured. The present invention also has a configuration in which the retractable locking lever 110 is indirectly rotated to the locking end position side through another member by abutting with another member different from the retractable locking lever 110. Is included in the technical scope. Specifically, for example, when the door-side pressing member 93 abuts on the game board 11, it is pushed by the game board 11 and the retractable locking lever 110 is rotated to the locking end position side. May be. At this time, the “other member” that contacts the door-side pressing member 93 is not limited to the game board 11, and may be a member provided on the game board 11 or a member provided on the inner frame 75.
