  The game board 80 includes a wooden plywood and a sheet material that covers a front plate surface of the plywood, and the front surface of the game board 80 is exposed to the front side of the resin base 60 through an open portion of the game board housing portion 61. . In the exposed portion, that is, the front surface of the game board 80, a game area PE in which game balls flow down is formed. As already described, the game area PE is covered with the glass panel 32. In the glass panel 32, the gap between the front surface of the game board 80 is slightly larger than the diameter of the game ball, that is, the game balls flowing down the game area PE are not lined up and down in the same place of the game area PE. Are arranged as follows. Thereby, the ball blockage in the game area PE is suppressed. Note that the game board 80 is not limited to wooden, and can be made of a synthetic resin material.

  Hereinafter, the game board 80 (in particular, various configurations arranged in the game area PE) will be described with reference to FIG. FIG. 6 is a front view of the game board 80.

  The game board 80 is formed with a plurality of large and small openings penetrating in its own thickness direction (front-rear direction) by performing router processing. Each opening is provided with a general winning port 81, a variable winning device 82, operating ports 83a and 83b, a through gate 84, a variable display unit 85, and the like. When game balls enter the general winning port 81, the variable winning device 82, and the operation ports 83a and 83b, the game balls are detected by a detection switch described later, and a predetermined number of award balls are paid out based on the detection result. The In addition, an out port 86 is provided at the lowermost part of the game board 80, and game balls that have not entered various winning ports etc. are discharged from the game area PE through the out port 86.

  In addition, in the game board 80, a number of nails 87 are implanted in order to disperse and adjust the flow path of the game ball as appropriate, and various members (functions) such as a windmill are arranged. The flow path of the game ball is differentiated by various configurations such as the nails 87 and the windmills, and adjusted so that the winning to the above-described general winning opening 81 and the like occurs with an appropriate establishment.

  The variable winning device 82 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which a game ball is easy to win in the case of a big hit. As a release mode of the variable winning device 82, a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winnings is regarded as one round, and the variable winning device 82 is opened by a plurality of rounds (for example, 15 rounds). It is set to be repeated as the upper limit.

  The variable display unit 85 is disposed at the upper center of the game board 80, and the operation ports 83a and 83b are disposed below the variable display unit 85. More specifically, the operation ports 83a and 83b are arranged side by side with the operation port 83a on the upper side and the operation port 83b on the lower side. The variable display unit 85 and the operation ports 83a and 83b are portions that control game play, and the player's attention is likely to be gathered. By arranging the variable display unit 85 and the operation ports 83a and 83b side by side in the center of the gaming machine, the movement amount of the line of sight between the two is suppressed, which contributes to the reduction of the burden on the player's eyes.

  The variable display unit 85 includes a symbol display device 94 that variably displays symbols with a winning in the operation ports 83a and 83b as a trigger. The symbol display device 94 is configured as a liquid crystal display device including a liquid crystal display (display screen 94a), and the display content is controlled by a display control device described later. Specifically, on the display screen 94a, symbols are displayed side by side in the upper, middle, and lower levels, and these symbols are variably displayed as they are scrolled in the horizontal direction. When a big hit occurs, a predetermined combination of symbols is stopped and displayed on a preset active line, and a transition is made to a special gaming state. The display mode on the display screen 94a may be changed as follows. That is, the symbols may be displayed side by side on the left, middle, and right, and the symbols may be displayed in a variable manner by scrolling up and down.

  The variable display unit 85 includes a center frame 95 formed so as to surround the symbol display device 94. A first specific lamp unit 96 and a second specific lamp unit 97 are provided on the center frame 95. Reservation lamp portions 98 and 99 are provided at the upper and lower portions of the center frame 95, respectively. The lower holding lamp unit 98 corresponds to the symbol display device 94 and the first specific lamp unit 96, and the number of times that the game ball has passed through the operation port 83 is held up to four times, and the holding lamp unit 98 is turned on. The number of reserved items is displayed. The upper holding lamp unit 99 corresponds to the second specific lamp unit 97, and the number of times that the game ball has passed through the through gate 84 is held up to four times, and the number of holdings is displayed by lighting the holding lamp unit 99. It has become so.

  Referring again to FIG. 5, below the game board housing portion 61 (game board 80) in the resin base 60, a game ball that launches a game ball into the game area PE based on the operation of the game ball launch handle 41. A firing mechanism 110 is provided. As shown in FIG. 4, the game ball launching mechanism 110 includes a solenoid 111 that launches a game ball placed at a predetermined launch standby position, and a launch rail 112 that defines the launch direction of the game ball launched by the solenoid 111. A ball feeding device 113 for supplying a game ball to the launch standby position and a base plate 114 on which the various configurations 111 to 113 are mounted are provided as main components, and the base plate 114 is interposed via a reinforcing plate described later. Are attached to the resin base 60.

  The firing rail 112 is fixed to the base plate 114 in an inclined state so as to be inclined upward toward the game board 80 side. A ball stopper that holds the game ball supplied from the ball feeding device 113 at the above-described firing standby position is disposed at a position closer to the downstream end portion (that is, the lower end portion) of the firing rail 112. The solenoid 111 is arranged at a position further downstream than the ball stopper.

  The solenoid 111 is electrically connected to a power source / launch control device described later. Based on the output of the electrical signal from the power supply / launch control device, the output shaft of the solenoid 111 reciprocates in the expansion / contraction direction, so that the game ball placed at the launch standby position is on the game board 80 side, more specifically, the game. It is driven out toward the guide rail 100 mounted on the board 80.

  The guide rail 100 forms a game area PE together with a game area partition member so that the outer shape of the game area PE is substantially circular. In addition, the guide rail 100 includes an inner rail 101 and an outer rail 102 arranged so as to face each other with a gap slightly larger than the diameter of the game ball, and a single guide passage 103 is defined by both the rails 101 and 102. Is formed. The guide passage 103 includes an inlet portion 104 that is opened to the tip side (obliquely downward) of the firing rail 112, and an outlet portion 105 that is located above the gaming area PE. The game ball fired based on the operation of the solenoid 111 is guided to the game area PE by moving in the order of the firing rail 112 → the guide rail 100 (the entrance portion 104 → the exit portion 105). In the game board 80, a reversal prevention member 106 for preventing the reversal of the game ball reaching the game area PE into the guide passage 103 is attached to the front side of the exit portion 105, specifically near the tip of the inner rail 101. Thus, it is possible to prevent the subsequent launch of the game ball from being hindered by the game ball that has reached the game area PE first.

  Each of the rails 101 and 102 constituting the guide rail 100 has an arc shape centered at a substantially central portion of the game area PE. For this reason, the game ball passing through the guide passage 103 is likely to move (slide or roll) along the outer rail 102, that is, in contact with the outer rail 102 due to the centrifugal force generated by itself.

  The guide rail 100 is operated when the game ball launch handle 41 is operated to such an extent that the game ball can reach the game area PE, that is, when the operation amount of the game ball launch handle 41 exceeds the first specified amount. In addition, the game ball launched from the launch rail 112 is formed so as to land on the entrance portion 104 of the guide rail 100, specifically the specific portion SP located on the extension of the launch rail 112 in the outer rail 102.

  The outer rail 102 is formed so that the direction of the tangent TL at the specific portion SP is substantially the same as the rail direction of the firing rail 112. By aligning the direction of movement of the launched game balls and the direction of the tangent TL of the specific part SP, the impact caused by the landing of the game balls is reduced and the rebound of the game balls is suppressed. Is possible.

  The outer rail 102 includes a plurality of fixing pins 102 a as fixing means for fixing the outer rail 102 to the game board 80. The fixed pin 102a is disposed along the outer rail 102, and the specific portion SP is set between the fixed pins 102a. As a result, it is possible to allow slight deformation (elastic deformation) of the outer rail 102 at the specific part SP, and to reduce the impact when the game ball lands on the specific part SP.

  As shown in FIG. 5, the guide rail 100 and the launch rail 112 are arranged so that the entrance portion 104 of the guide rail 100 and the tip portion of the launch rail 112 face each other diagonally across the lower edge of the game board 80. Has been. That is, both the rails 100 and 112 are arranged such that the entrance portion 104 of the guide rail 100 and the tip portion of the firing rail 112 are shifted left and right in the vicinity of the lower end edge of the game board 80. Thus, a gap of a predetermined interval is formed between the entrance portion 104 of the guide rail 100 and the firing rail 112 while bringing both rails 100 and 112 close to the lower end edge of the game board 80.

  A foul ball passage 55 is disposed below the gap formed in this way. The foul ball passage 55 is integrally formed with the passage formation unit 50 of the front door frame 14. If the game balls launched from the game ball launching mechanism 110 do not reach the game area PE and return as foul balls in the guide passage 103, the foul balls enter the foul ball passage 55 through the gap. It becomes. The foul ball passage 55 communicates with the front door side lower tray passage 52, and the game balls that have entered the foul ball passage 55 are discharged to the lower tray 29a shown in FIG. This suppresses interference between the foul ball and the next game ball to be launched.

  A through hole that penetrates the resin base 60 in the front-rear direction is formed on the left side of the firing rail 112 in the resin base 60 (specifically, the side that supports the front door frame 14), and a passage forming member is formed in the through hole. 121 is disposed. The passage forming member 121 is screwed to the resin base 60 and has a main body side upper dish path 122 and a main body side lower dish path 123. The upstream side of the main body side upper dish passage 122 and the main body side lower dish passage 123 communicates with a game ball distributing section described later. A receiving portion 53 of a passage forming unit 50 attached to the front door frame 14 is inserted below the passage forming member 121, and a front door side upper plate passage 51 is provided below the main body side upper plate passage 122. The front door side upper dish path 51 is disposed below the main body side lower dish path 123 (see FIG. 2).

  In the resin base 60, a shutter 124 that restricts the outflow of game balls from the main body side upper dish path 122 and the main body side lower dish path 123 is provided below the passage forming member 121. The shutter 124 is supported by the resin base 60 in a state where the shutter 124 can be switched between a blocking position where the outlet portions of both passages are narrowed to prevent the gaming ball from flowing out and an allowable position where the gaming ball is allowed to flow out. Further, a biasing member that biases the shutter 124 toward the blocking position is attached to the resin base 60. When the front door frame 14 is opened with respect to the inner frame 13, the shutter is driven by the biasing force of the biasing member. 124 is configured to remain in the blocking position. Thereby, when the front door frame 14 is opened in a state where the game balls are stored in the main body side upper tray passage 122 or the main body side lower tray passage 123, the disadvantage that the stored balls spill out is avoided. . In contrast, when the front door frame 14 is closed, the shutter 124 is pushed back to the allowable position against the urging force by the receiving portion 53 provided in the passage forming unit 50 of the front door frame 14. In this state, the main body side upper tray passage 122 and the front door side upper tray passage 51 communicate with the main body side lower tray passage 123 and the front door side lower tray passage 52, respectively, and the movement of the game ball is permitted. Become.

  Next, the back configuration of the inner frame 13 (the resin base 60 and the game board 80) will be described with reference to FIG. FIG. 7 is a rear view of the inner frame 13.

  A bearing fitting 132 is attached to the rotation base end side (the right side in FIG. 7) of the back surface of the resin base 60. A bearing portion 133 is formed on the bearing bracket 132 so as to be separated from each other in the vertical direction, and the back pack unit 15 is rotatably attached to the inner frame 13 by these bearing portions 133. A plurality of fixing levers 134 for fixing the back pack unit 15 to the inner frame 13 are provided on the back surface of the resin base 60.

  As described above, the bottom portion of the game board housing portion 61 in the resin base 60, that is, the counter opening 62 penetrates in the thickness direction of the resin base 60 and opens to the back side of the resin base 60. The center opening 64 is covered from the front side of the inner frame 13 by the game board 80 housed in the game board housing part 61. Various components such as a control device are mounted on the back of the game board 80, and these various components are exposed to the back side of the inner frame 13 through the central opening 64. Here, the configuration of the back surface of the game board 80 will be described in detail with reference to FIG. FIG. 8 is a perspective view of the game board 80 as seen from the rear.

  On the back of the game board 80, a base member 141 made of synthetic resin for mounting the variable display unit 85 on the game board 80 is fixed. The pedestal member 141 has a substantially box shape opened to the game board 80 side, and covers almost the entire rear surface of the game board 80. A part of the base member 141 protrudes to the back side of the resin base 60 through the central opening 64 of the resin base 60, and the symbol display device 94 described above and the symbol display device 94 are driven with respect to the protruding portion.

It is like that.

(Configuration related to arrangement of game board 80)
As already described, the game board 80 in the present embodiment is configured to be detachable from the resin base 60, facilitating the placement work at the mounting completion position and improving the positional accuracy at the mounting completion position. Various ideas are made. Here, the configuration related to the arrangement of the game board 80 will be described in detail with reference to FIGS. 11 is a partial cross-sectional view taken along line AA of FIG.

  As shown in FIG. 5, the left side wall 67 of the inner frame 13 (specifically, the resin base 60), that is, the wall 67 on the side supporting the front door frame 14 is displaced forward of the game board 80. A plurality of stopper portions 271 to be suppressed are provided. Each stopper portion 271 protrudes from the inner wall surface of the left side wall portion 67 to the game board housing portion 61 side, and abuts against the game board 80 (specifically, a rail cover) from the front of the pachinko machine 10 (FIG. 4). reference). Moreover, each stopper part 271 is accommodated in the game board accommodating part 61, and the protrusion to the front door frame 14 side is suppressed.

  The stopper portions 271 are arranged at positions near the upper end and the lower end of the game board 80, respectively, so that the displacement of the game board 80 can be suppressed in a well-balanced manner. If it supplements regarding arrangement | positioning of the stopper part 271, as shown in FIG. 4, the stopper part 271U close | similar to an upper end will protrude in the rotation base end side of the game board 80 in the said guide rail 100 (specifically outer rail 102). The stopper portion 271L closer to the lower end is disposed below the convex portion. Accordingly, the stopper portion 271 and the guide rail 100 are preferably allowed to coexist on the front side of the game board 80, and the compression of the game area PE due to the adoption of the stopper portion 271 is suppressed.

  A metal plate member 281 is disposed on the inner frame 13 along the leading edge of the left wall portion 67. The plate member 281 has a long shape extending across both the upper frame portion 13 a and the lower frame portion 13 b of the inner frame 13, and both end portions of the plate member 281 are the left frame portion of the inner frame 13. In addition to being fixed (screwed) to 13c, an intermediate portion of the plate member 281 is fixed (screwed) to the stopper portion 271 described above. Thereby, the part connected with the outer frame 11 and the front door frame 14 in the inner frame 13 is reinforced, and also the deformation | transformation of the stopper part 271 is suppressed.

  The stopper portion 271 and the counter plate portion 62 described in detail above constitute an insertion portion 290 into which one side portion of the game board 80 can be inserted (see FIG. 11). The insertion portion 290 is located on the rotation base end side of the front door frame 14 and is the same to allow the insertion of the game board 80 from the side opposite to the side supporting the front door frame 14 in the inner frame 13. The inner frame 13 is open to the rotating front end side (right side wall 68 side). In particular, the gap dimension between the stopper portion 271 and the opposing plate portion 62 (specifically, a portion excluding ribs described later) is set larger than the thickness dimension of the game board 80. Thus, the game board 80 can be inserted into the insertion portion 290 from obliquely forward, and the game board 80 inserted into the insertion portion 290 can be rotated around the insertion portion 290. Further, by inserting the insertion port of the insertion portion 290 obliquely forward, the game board 80 extends to the rear of the front door frame 14 when the game board is inserted, the right side frame portion 13d of the inner frame 13 (see FIG. 5), etc. To prevent interference.

  In addition, the chamfering is given to the site | part facing the game board 80 in the front-end | tip part of the stopper part 271, and the entrance part of the insertion part 290 is expanded. Thereby, the said gap dimension is enlarged and the catching of the stopper part 271 and the game board 80 at the time of inserting the game board 80 diagonally is suppressed.

  Below the insertion portion 290 (the stopper portion 271 group), specifically, at a position where the left side wall portion 67 and the lower side wall portion 66 intersect in the inner frame 13 (see FIG. 11), the game board 80 inserted into the insertion portion 290 is inserted. A temporary placement portion 125 that can be temporarily placed is provided. The temporary placement portion 125 is formed in the passage forming member 121 and has a surface shape facing the insertion portion 290 side (upward). The temporary placement portion 125 is not necessarily formed in the passage forming member 121 and can be formed in the resin base 60.

  The temporary placement portion 125 is located above the lower wall portion 66 of the game board housing portion 61 and faces the lower end portion of the game board 80. On the other hand, a notch portion 88 corresponding to the temporary placement portion 125 is formed in the lower corner portion of the rotation base end side of the game board 80 (see FIG. 6). When the game board 80 is inserted into the insertion part 290 and rotated, the cutout part 88 of the game board 80 is temporarily placed (temporarily placed) with respect to the temporary placement part 125, so At least a part of the weight of 80 is supported by the resin base 60 of the inner frame 13. As a result, the work load when the game board 80 is mounted is reduced, and the rotation operation of the game board 80 is facilitated.

  In addition, the temporary placement portion 125 extends to the opening side of the insertion portion 290 from the insertion portion 290. Thus, the game board 80 can be temporarily placed before being inserted into the insertion portion 290, which contributes to further facilitation of work.

  As shown in FIG. 11, the portion of the opposing plate portion 62 of the inner frame 13 that is closer to the turning tip of the game board 80 than the stopper portion 271, specifically the edge on the central opening 64 side, And a game board 80 (specifically, a rail cover) is in contact with the rib. As described above, the gaming board 80 abuts against the rib of the opposing plate portion 62, so that the displacement of the gaming board 80 toward the back side of the gaming board housing portion 61 is restricted.

  Particularly in the present embodiment, the front-rear width dimension of the insertion portion 290 is set slightly smaller than the thickness dimension of the game board 80 including the rail cover, and the game board 80 is disposed at the installation completion position. Then, the game board 80 is in a state of strong interference with the insertion portion 290. In this way, by causing the game board 80 to strongly interfere with the insertion portion 290, it is possible to suppress variations in the front and rear positions of the game board 80.

  However, when adopting such a configuration, it is not preferable that the insertion of the game board 80 into the insertion portion 290 becomes difficult. Therefore, as described above, the contact position between the game board 80 and the rib of the opposing plate portion 62 is located closer to the rotating front end side of the game board 80 than the contact position between the game board 80 and the stopper portion 271. By adopting the configuration, it is possible to suitably suppress the position variation in the state where the game board 80 is arranged at the mounting completion position while facilitating the insertion of the game board 80.

(Configuration for inner frame reinforcement)
Further, in the present embodiment, a reinforcing plate 350 that reinforces the inner frame 13 (specifically, the resin base 60) is provided, and the reinforcing plate 350 suppresses bending, twisting, and the like of the resin base 60. Improvement of position accuracy and the like are attempted. Here, the reinforcing plate 350 will be described with reference to FIGS. 12, 13, and 14. 14 is a partial cross-sectional view taken along line BB in FIG.

  The reinforcing plate 350 is formed by bending a metal plate, and has a long shape extending across the left and right end portions of the resin base 60, that is, the left and right frame portions 13 c and 13 d of the inner frame 13. In the resin base 60, a plate installation portion 69 on which the reinforcing plate 350 can be installed is formed along the lower side wall portion 66 (in other words, the lower edge of the game board 80) below the game board housing portion 61. A reinforcing plate 350 is attached to the plate installation portion 69 from the front of the pachinko machine 10.

  The plate installation portion 69 is continuous with the lower side wall portion 66 forming the game board housing portion 61 and has a planar shape facing the front of the pachinko machine 10. The reinforcing plate 350 has a base portion 361 corresponding to the plate installation portion 69, and when the base portion 361 comes into surface contact with the plate installation portion 69, the front-rear position with respect to the resin base 60 is defined. ing.

  The base portion 361 has a long shape extending in the longitudinal direction of the reinforcing plate 350, and a plurality of round holes 362 penetrating in the front-rear direction are formed in the center portion of the base portion 361. The left and right positions and the upper and lower positions of the reinforcing plate 350 with respect to the resin base 60 are defined by inserting the protrusions 70 formed on the resin base 60.

  In addition, a plurality of through holes 363 are formed in the base portion 361 so as to be aligned in the longitudinal direction, and screws 391 inserted through the through holes 363 are screwed to the plate installation portion 69. It is integrated with the resin base 60. In particular, in the base portion 361, an arm portion 364 extending toward the plate member 281 is formed at an end portion on the side where the support fittings 71 and 72 are provided, and this arm portion 364 is connected to the plate member 281. It is fastened together with the plate member 281 together with the resin base 60 while being sandwiched between the resin base 60.

  As shown in FIG. 14, the base portion 361 is located below the game board 80 and faces the lower end surface of the game board 80 from below. The upper end edge of the base portion 361 protrudes slightly above the boundary portion between the plate installation portion 69 and the lower side wall portion 66, and the upper end edge extends to the rear along the lower side wall portion 66. Is formed. The extending portion 371 has a flat plate shape parallel to the lower wall portion 66, and is sandwiched between the lower wall portion 66 and the lower end portion of the game board 80. The rear end edge of the extending part 371 is located behind the game board 80, and the rear end edge rises upward along the opposing plate part 62 of the resin base 60 and faces the back surface of the game board 80. A facing portion 381 is formed. That is, the base plate 361, the extended portion 371, and the facing portion 381 constitute the reinforcing plate 350 in a crank shape, which contributes to improving the strength of the reinforcing plate 350.

  At the edge of the opposing plate portion 62 of the resin base 60, standing portions 73 are formed so as to stand forward with respect to the lower side wall portion 66 with the facing portion 381 interposed therebetween. In addition, the facing portion 381 is fitted in a region sandwiched between the lower wall portions 66.

  As shown in FIG. 13, positioning protrusions 79 that define the left and right positions of the game board 80 are provided above the lower side wall portion 66 of the opposing plate portion 62, specifically, at a portion facing the opposing portion 381 of the reinforcing plate 350. Is provided. Hereinafter, the positioning projection 79 and the structure associated therewith will be described with reference to FIGS. 6, 12, 13, and 14. FIG.

  As shown in FIG. 13, the positioning projection 79 is disposed in the vicinity of the base portion of the lower side wall portion 66, and stands on the game board 80 side from the front surface of the opposing plate portion 62. An escape hole 382 is formed in the facing portion 381 of the reinforcing plate 350 so as to avoid interference with the positioning protrusion 79, and the tip end portion of the positioning protrusion 79 protrudes toward the game board 80 through the escape hole 382. The protruding portion is inserted into a through hole 91 (see FIG. 6) formed in the game board 80, whereby the movement of the game board 80 in the left-right direction is restricted.

  The positioning protrusion 79 is integrally formed with the counter plate portion 62. The counter plate portion 62 is formed by connecting a plurality of flat plate portions, and among the flat plate portions, the one closest to the inlet portion 104 of the guide rail 100 is connected to the corner portion of the peripheral wall portion 63. A positioning projection 79 is disposed on the flat plate portion. That is, the positioning projection 79 is disposed on the flat plate portion that is continuous with the lower wall portion 66 and the left wall portion 67 that constitute the peripheral wall portion 63. In this way, in the flat plate portion connected to a plurality of adjacent wall portions, the deformation when a load is applied to the flat plate portion is suppressed, as compared with the case where it is connected to one wall portion. The amount of displacement of the flat plate portion can be reduced. In particular, by arranging the positioning protrusion 79 on the flat plate portion connected to the corner portion closest to the entrance portion 104 of the guide rail 100, the above-described displacement amount is suitably reduced, and the positional accuracy of the positioning protrusion 79 is improved. Can contribute.

  The through hole 91 formed in the game board 80 is formed so as to allow variation in the vertical position while suppressing variation in the horizontal position of the positioning projection 79. Specifically, the positioning projection 79 has a cylindrical shape, whereas the through hole 91 has a long hole shape that expands in the vertical direction. Thereby, it is easy to avoid the weight of the game board 80 from being applied to the positioning projection 79, and the deterioration of the position accuracy of the left and right positions due to the positioning projection 79 is suppressed.

  As shown in FIGS. 4 and 6, the positioning protrusion 79 and the through hole 91 are located behind the entrance portion 104 of the guide rail 100, specifically, behind the outer rail 102 in the front view of the game board 80. It is arranged in the overlapping position. More specifically, the positioning protrusion 79 and the through hole 91 are arranged at positions that overlap the specific portion SP on the outer rail 102 in the front and rear directions when the game board 80 is viewed from the front. In this way, by defining the left and right positions of the game board 80 at positions close to the specific part SP, it is easy to suppress the variation in the position of the outer rail 102 and the variation in the landing position of the game ball.

  As shown in FIG. 14, the rising amount of the positioning protrusion 79 is set to be smaller than the depth dimension of the through hole 91, and the tip of the positioning protrusion 79 is located at the intermediate position of the through hole 91. This is a device for making the alignment of the through hole 91 and the positioning projection 79 suitable in the configuration in which the game board 80 is rotatably supported by the inner frame 13.

  A rail support member 107 that supports the outer rail 102 is attached to a portion of the through hole 91 where the positioning projection 79 does not reach. That is, the front half of the through hole 91 is used as a region for positioning the game board 80, and the rear half of the through hole 91 is used as a region for mounting the rail support member 107.

  The rail support member 107 includes a fitting portion 108 that fits into the through hole 91 and a contact portion 109 that comes into contact with the outer surface of the outer rail 102, and the fitting portion 108 and the contact portion 109 are combined. It is integrally formed of a resin material. When the game ball launched from the game ball launching mechanism 110 lands on the outer rail 102 (specifically, the specific portion SP), a part of the impact generated by the landing of the game ball is distributed to the rail support member 107 and the game board 80. The outer rail 102 can be protected.

  The rail support member 107 is disposed between the fixed pins 102a. By causing the rail support member 107 to contact the outer rail 102, the vibration of the outer rail 102 due to the landing of the game ball can be suppressed. As described above, the through hole 91 has a long hole shape, and the fitting portion 108 is formed so that its outer shape matches the inner shape of the through hole 91. This makes it easy to disperse the impact on the game board 80 while avoiding the rail support member 107 from rotating (displacement) due to the impact or the like at the time of the game ball collision described above. Moreover, the deterioration of the protective function is suppressed by making it difficult for the rail support member 107 to be displaced.

  As described above in detail, the through hole 91 is used for positioning the game board 80 and mounting the rail support member 107, so that not only the position accuracy of the game board 80 but also the position accuracy of the rail support member 107 and the outer rail 102 are obtained. The position accuracy is improved. Thereby, the landing accuracy of the game ball on the specific part SP in the outer rail 102 can be improved.

(Fixed structure of game board 80)
As described above in detail, the inner frame 13 is in a locked state in which it is impossible to remove the game board 80 from the game board housing part 61, and the position from the game board housing part 61. A lock device 400 is provided that can be switched to an unlocked state that allows the game board 80 to be removed. As shown in FIG. 4, the locking device 400 is disposed on the inner frame 13 on the side opposite to the insertion portion 290, that is, on the right side wall portion 68, or on the insertion portion 290 side, specifically, the positioning protrusion 79. Are arranged in the vicinity of the game board 80, further arranged near the lower end of the game board 80 (near the game ball launching mechanism 110), or arranged near the upper end of the game board 80. .

  Each of these locking devices 400 has a common basic configuration, and only the configuration relating to the mounting of the locking device 400 and the configuration associated with the locking device 400 are slightly different. Therefore, first, the basic configuration of the locking device 400 disposed at a position that is arranged side by side with respect to the positioning projection 79 will be described with reference to FIGS. Will be described. 15A is a perspective view of the locking device 400 viewed from the front side, FIG. 15B is an exploded perspective view of the locking device 400, and FIG. 16 is a partial cross-sectional view taken along the line CC of FIG. In FIG. 16, for the sake of convenience, a part of the configuration of the lock device 400 (an operation lever 440 and a shaft pin 420 described later) is shown as viewed from the side of the pachinko machine 10.

  As shown in FIG. 13, the lock device 400 disposed near the lower end of the game board 80 is attached to the opposing plate portion 62 of the resin base 60 via the reinforcing plate 350 (specifically, the opposing portion 381). More specifically, as shown in FIG. 15 (b), the locking device 400 has a base plate 410 formed by bending a metal plate, and this base plate 410 is attached to the opposing portion 381 of the reinforcing plate 350. It is attached to the opposing board part 62 of the resin base 60 in the state installed from the front.

  More specifically, the base plate 410 has a flat plate portion 411 parallel to the facing portion 381 of the reinforcing plate 350, and the flat plate portion 411 is in surface contact with the facing portion 381. The flat plate portion 411 has a long plate shape extending in the same direction (left-right direction) as the longitudinal direction of the reinforcing plate 350, and two through holes 412 are formed side by side in the longitudinal direction. As shown in FIGS. 13 and 15B, screws 418 are inserted into the through holes 412 from the side opposite to the reinforcing plate 350 (front of the pachinko machine 10), and the inserted screws 418 are resin. The base plate 410 is fixed by being screwed to the counter plate portion 62 of the base 60. The numbers of through holes 412 and screws 418 are not limited to two and may be set arbitrarily.

  In the present embodiment, as described above, the reinforcing plate 350 is fixed on the basis of the base portion 361 of itself and the plate installation portion 69 of the resin base 60, and variations in molding or the like occur in the opposing plate portion 62 of the resin base 60. In such a case, a predetermined gap is generated between the facing portion 381 of the reinforcing plate 350 and the facing plate portion 62 due to the variation. When such a gap is generated, the opposing plate portion 62 is attracted to the opposing portion 381 side by screwing the screw 418. In other words, the strength of the facing plate portion 62 is set higher than that of the facing portion 381, and the tilting of the facing portion 381 toward the facing plate portion 62 when the screw 418 is screwed in is suppressed. . Thereby, the positional accuracy of the facing portion 381 with respect to the base portion 361 of the reinforcing plate 350 (that is, the positional accuracy of the base plate 410) is suitably secured.

  A cylindrical portion 413 extending in the front-rear direction is formed between the through holes 412 in the flat plate portion 411. The cylindrical portion 413 stands up from the front surface of the base plate 410 on the side opposite to the reinforcing plate 350, and an opening portion is formed in the flat plate portion 411 so as to communicate with the cylindrical portion 413.

  The shaft pin 420 is inserted into the tubular portion 413 in a rotatable state from the counter plate portion 62 side (rear side). The shaft pin 420 has its head portion 421 abutting against the back surface of the base plate 410, so that forward displacement is restricted. In addition, through holes 383 and 62a are formed in the facing portion 381 of the reinforcing plate 350 and the facing plate portion 62 of the resin base 60 to avoid interference with the head portion 421 of the shaft pin 420 (see FIG. 13). ).

  A pusher 430 that pushes the game board 80 from the back side is assembled to the shaft pin 420. The pusher 430 has a substantially flat main body 431 that covers the base plate 410 from the game board 80 side. The main body 431 is formed with an insertion portion 432 through which the shaft pin 420 is inserted. By inserting the shaft pin 420 into the insertion portion 432, the pusher 430 can slide in the direction of the central axis of the shaft pin 420.

  The main body portion 431 has a substantially rectangular shape when viewed from the front, and key grooves 433 are formed on the left and right side portions thereof in correspondence with the flange portions 414 erected forward from the left and right ends of the flat plate portion 411. By fitting the flange portion 414 to the key grooves 433, the pusher 430 is prevented from rotating around the central axis of the shaft pin 420. That is, the pusher 430 is allowed to slide around the central axis while allowing the sliding movement of the axial pin 420 in the central axial direction (front-rear direction) as described above.

  Further, on both long sides of the base plate 410, an urging portion 415 that urges the pusher 430 toward the game board 80 is formed. The urging portion 415 is formed by bending a part of the base plate 410 so as to be able to bend and deform in the front-rear direction, and a tip portion thereof abuts against the pusher 430 (specifically, the main body portion 431) from the back side. (See FIG. 16). More specifically, the urging portions 415 are formed obliquely with respect to the flat plate portion 411 (inclined to about 45 ° in the present embodiment) so that the distance between the two is widened on the tip side. Has been. Note that the “base plate 410” can also be referred to as the “plate spring 410” when attention is paid to the fact that the base plate 410 has a function as a plate spring.

  Incidentally, the body portion 431 is formed with a through hole 434 penetrating in the thickness direction (front-rear direction) of the main body portion 431 so as to correspond to the screw 418 described above, and the attaching / detaching operation of the screw 418 through the through hole 434 is allowed. ing.

  The thickness dimension (the length dimension in the axial direction) of the main body 431 is set to be smaller than the depth dimension of the concave portion 74 formed by the counter plate portion 62, the standing portion 73, and the lower side wall portion 66. The standby position where the protrusion from the recess 74 is suppressed and the front surface of the main body 431 is substantially flush with the front surface of the opposing plate portion 62, and the operation position where the game board 80 is displaced forward by protruding from the recess 74 And can be switched. Hereinafter, a configuration for realizing the switching of the position of the pusher 430 will be described.

  The distal end portion of the shaft pin 420 projects forward through the insertion portion 432 of the pusher 430, and an operation lever 440 that switches the position of the pusher 430 based on a specific operation is fixed to the projected distal end portion. Specifically, the operation lever 440 and the shaft pin 420 are fixed by the screw 449, so that the base plate 410 and the pusher 430 are prevented from falling off, and the various configurations are unitized.

  The operation lever 440 is allowed to rotate around the central axis of the shaft pin 420 and rotates integrally with the shaft pin 420. The operation lever 440 includes a cylindrical base portion 441 into which the shaft pin 420 is fitted, and an operation portion 446 that protrudes from both ends of the base portion 441 opposite to the pusher 430 in the radial direction of the base portion 441. And has a substantially T-shape as a whole.

  A protrusion 435 that stands on the side of the base 441 is provided on a portion of the pusher 430 that faces the end surface of the base 441. More specifically, the plurality of protrusions 435 are arranged so as to surround the insertion portion 432. On the other hand, the end surface of the base portion 441 has a planar shape extending in a direction orthogonal to the rotation center axis line (that is, the radial direction of the rotation center axis line), and can be stopped in a state where the protrusion 435 of the pusher 430 is in contact. The stopping portions 442 and 443 are formed. These stop portions 442 and 443 have different distances from the front end surface of the pusher 430 and are arranged apart from each other in the circumferential direction of the shaft pin 420. Hereinafter, for the sake of convenience, one having a larger distance from the front end surface of the pusher 430 will be referred to as a “first stopping portion 442”, and the other having a smaller distance than the first stopping portion 442 will be referred to as a “second stopping portion 443”.

  In addition, a connecting portion 444 that connects the first stopping portion 442 and the second stopping portion 443 is formed on the end surface of the base portion 441. The connecting portion 444 has a curved surface shape that smoothly connects the first stopping portion 442 and the second stopping portion 443. By switching the projection 435 of the pusher 430 along the connecting portion 444, switching of the stopping state at each of the stopping portions 442 and 443 is allowed. Note that the connecting portion 444 may have a planar shape that is inclined from the second stopping portion 443 toward the first stopping portion 442.

  The protrusions 435, the stop portions 442 and 443, and the connecting portion 444 constitute a switching unit that switches the position of the pusher 430, and the lock device 400 includes a plurality of switching units that have one of these various configurations (this embodiment). 3) are provided. These switching means are arranged side by side at equal intervals in the circumferential direction of the shaft pin 420. Thereby, it is suppressed that the stress which distorts the operation lever 440 with the urging | biasing force of the urging | biasing part 415 arises. In addition, it is also possible to change the arrangement | positioning object of the protrusion 435, the stop parts 442,443, and the connection part 444. FIG. In other words, the pusher 430 may be provided with a configuration corresponding to the retaining portions 442 and 443 and the connecting portion 444, and the base portion 441 may be provided with a configuration corresponding to the protrusion 435.

  When the locking device 400 is in the unlocked state, the protrusions 435 of the pusher 430 come into contact with the second stopping portions 443, so that the pusher 430 is prevented from protruding from the recess 74. In this case, since the second stopping portion 443 is orthogonal to the urging direction by the urging portion 415, the operation lever 440 is held in the unlocked position. In a state where the operation lever 440 is held at the unlock position, the operation unit 446 faces in the horizontal direction (lateral direction).

  Here, the switching operation of the locking device 400 will be described with reference to FIG. FIG. 17 is a schematic diagram illustrating a switching operation of the lock device 400.

  When the lock device 400 is switched to the locked state, the operation lever 440 is rotated clockwise as shown in FIG. 17A to FIG. The protrusion 435 moves from the second stop 443 to the first stop 442 via the connecting portion 444. Thereby, the pusher 430 protrudes from the recessed part 74, and it will be in the state which pushes the game board 80 from the back side. In this case, since the first stopping portion 442 is orthogonal to the urging direction by the urging portion 415, the operation lever 440 is held in the locked position. In a state where the operation lever 440 is held at the lock position, the operation unit 446 is inclined so as to face the middle between the horizontal direction and the vertical direction.

  An insertion portion 92 corresponding to the operation portion 446 is formed in the game board 80, and the operation portion 446 protrudes forward from the front surface of the game board 80 through the insertion portion 92. More specifically, the insertion portion 92 penetrates in the thickness direction of the game board 80, and extends from the rotation base end side of the game board 80 to the rotation front end side, more specifically in the horizontal direction. When the device 400 is in the unlocked state, the passage of the operation unit 446 is allowed, and when the lock device 400 is in the locked state, the passage of the operation unit 446 is prevented. For this reason, when the locking device 400 is switched to the locked state, a portion of the operation unit 446 facing the front surface of the game board 80 comes into contact with the game board 80, and the biasing force of the biasing part 415 described above. Is prevented from moving the game board 80. That is, the operation unit 446 also has a function as a stopper unit that prevents the game board 80 from moving.

  When the lock device 400 is switched to the unlocked state, as shown in FIGS. 17B to 17A, the operation lever 440 is rotated counterclockwise so that the operation unit 446 becomes horizontal. Manipulate. As a result, the pusher 430 is retracted to the concave portion 74 side, and the bias of the game board 80 is released, and the operation lever 440 (operation unit 446) is allowed to pass through the insertion portion 92. As a result, the game board 80 can be taken out from the game board housing portion 61.

  A common point and a difference between the lock device 400L arranged near the lower end of the game board 80 and the lock device 400U arranged near the upper end of the game board 80 will be described. Like the locking device 400L, the locking device 400U includes a base plate 410, a shaft pin 420, a pusher 430, and an operation lever 440, and these various components are unitized. The locking device 400L is installed on the reinforcing plate 350, but the locking device 400 is different in that it is installed on the opposing plate portion 62.

  As described in detail above, if attention is paid to the fact that the front and rear positions of the game board 80 are defined by the locking device 400, it can be said that the locking device 400 has a positioning function.

  Next, the relationship between the locking device 400 and the positioning protrusion 79 will be described with reference to FIGS.

  As shown in FIG. 12, the locking device 400 is arranged so that the front end portion of the operation portion 446 is positioned forward of the tip end of the positioning projection 79. For this reason, when the game board 80 is rotated toward the mounting completion position, the operation unit 446 of the lock device 400 first enters the insertion part 92 of the game board 80, and then the positioning protrusion 79 penetrates the game board 80. It will enter the hole 91. More specifically, the positioning projection 79 enters the through hole 91 in a state where at least a part of the operation portion 446 is fitted in the insertion portion 92. The inner shape of the insertion portion 92 is formed to be slightly larger than the outer shape of the operation portion 446, and movement variation of the operation portion 446 within the insertion portion 92 is limited. That is, when the operation unit 446 enters the insertion unit 92, assembly variation of the game board 80 (for example, position variation in the left-right direction) is suppressed. As described above, with the configuration in which the positioning protrusion 79 enters the through hole 91 in a state where the variation in the position of the game board 80 is suppressed, there arises a disadvantage that the positioning protrusion 79 does not fit into the through hole 91 well. It is difficult.

  In particular, in the present embodiment, the locking devices 400 are arranged on the left and right sides of the positioning projection 79. That is, the positioning protrusion 79 is disposed between the two locking devices 400. The insertion portion 92 corresponding to each lock device 400 has a left insertion portion 92 opened to the rotation base end side of the game board 80 and a right insertion portion 92 opened to the rotation distal end side of the game board 80. The position of the lock device 400 in a direction other than the opened direction is suppressed. In this way, by providing each lock device 400 with a positional shift suppression function, it is possible to prevent a burden from being concentrated on one lock device 400.

  In particular, the insertion portion 92 corresponding to the lock device 400 on the left side is continuous with the cutout portion 88 of the game board 80 and is open to the rotation base end side of the game board 80.

  In the configuration in which the locking device 400 is arranged on both the left and right sides of the entrance portion 104 of the guide rail 100, one of the both locking devices 400 located closer to the rotation base end side of the game board 80 than the entrance portion 104 is. There is a concern that the insertion of the game board 80 into the insertion portion 290 is likely to be hindered. It is assumed that such an inconvenience becomes conspicuous by arranging the entrance portion 104 at substantially the center in the width direction of the game board 80.

  Further, since the main body side upper dish passage 122 and the main body side lower dish passage 123 are positioned higher than the respective dishes 28a and 29a, the game balls are guided to the same dishes 28a and 29a by using their own weights. It is possible to move the game ball. However, in the present embodiment in which the game area PE is expanded, the expansion of the game area PE tends to limit the arrangement of the main body side upper dish passage and the main body side lower dish path 123. This can be a factor that makes it difficult to guide the game balls to the dishes 28a and 29a.

  In this regard, in the present embodiment, the notch 88 is formed in the game board 80 so that the main body side upper dish path and the main body side lower dish path 123 and the game board 80 can coexist. . That is, it is possible to arrange the positions of the main body side upper dish passage and the main body side lower dish path 123 higher than the respective dishes 28a and 29a while expanding the game area PE. Further, as described above, the left insertion portion 92 is formed so as to be continuous with the notch 88, and the insertion portion 92 is opened to the rotation base end side of the game board 80, so that the insertion portion 290 has the game board. Interference between the lock device 400 on the left side and the insertion portion 92 when inserting 80 can be avoided. Thereby, the arrangement of the main body side upper dish passage and the main body side lower dish path 123 and the expansion of the game area PE are preferably realized, and further, the improvement of positioning accuracy and the ease of inserting the game board 80 are preferably realized. Both are compatible.

(Configuration related to positioning of game ball launching mechanism 110)
As described in detail above, various arrangements have been made with respect to the arrangement of the game board 80, and the positional accuracy is suitably ensured. In the present embodiment, a contrivance is made to improve the accuracy of the relative position between the game board 80 and the game ball launching mechanism 110 (specifically, the launch rail 112). Hereinafter, the relationship between the reinforcing plate 350 and the game ball launching mechanism 110 will be supplementarily described with reference to FIGS. 13 and 16 again.

  As shown in FIG. 13, the base plate 114 of the game ball launching mechanism 110 has a horizontally long shape extending in the same direction as the longitudinal direction of the reinforcing plate 350. 113, a solenoid 111, and the like are arranged. The leading end portion of the firing rail 112, that is, the end portion on the inlet portion 104 side of the guide rail 100 is located at the upper end of the base plate 114, and the gaming ball launching mechanism 110 has the upper end portion of the base plate 114 as the base portion 361 of the reinforcing plate 350. It is installed in a surface contact state. That is, the front and back positions of the game ball launching mechanism 110 are defined by the surface contact of the base plate 114 with the base portion 361. In particular, the base portion 361 has a predetermined width in the vertical direction, and the base plate 114 is disposed such that the tip portion of the firing rail 112 is positioned in front of the base portion 361, The overlap (contact area) with the base plate 114 is earned.

  As described above, the base portion 361 and the base plate 114 extend in the same direction, and the contact range between the both extends similarly in the same direction. Specifically, the base plate 114 is in contact with the base portion 361 across both left and right ends. In particular, by mounting the firing rail 112, the solenoid 111, and the like on the base plate 114, the positional relationship between them can be made suitable, and each configuration is individually installed on the reinforcing plate 350. In comparison, the contact range is easily expanded.

  Projections projecting toward the resin base 60 on a portion of the base plate 114 closer to the tip of the firing rail 112 (end on the guide rail 100 side) and a portion on the opposite side (specifically, above the solenoid 111) 117 and 118 are formed, respectively. Insertion holes 365 are formed in the base portion 361 of the reinforcing plate 350 so as to correspond to the protrusions 117 and 118, and the protrusions 117 and 118 are fitted into the insertion holes 365, whereby the game ball launching mechanism 110. Left and right positions and vertical positions are defined. In particular, the insertion hole 365 near the tip of the firing rail 112 has a round hole shape, and the other insertion hole 366 has a long hole shape extending in the left-right direction. It is defined based on the portion closer to the tip.

  Further, a through hole 119 penetrating in the front-rear direction is formed between the protrusions 117 and 118 in the base plate 114. The screw 120 inserted into the through hole 119 is screwed to the plate setting portion 69 through the through hole 367 formed in the base portion 361 of the reinforcing plate 350, whereby the game ball launching mechanism 110 (base plate 114) is made of resin. It is integrated with the base 60.

  As shown in FIG. 16, the front surface of the base plate 114 is configured to be flush with the front surface of the game board 80, and the firing rail 112 mounted on the front surface of the base plate 114 is in front of the front surface of the game board 80. Is located. Accordingly, the game ball is prevented from being caught on the lower edge of the game board 80 when the game ball jumping out from the launch rail 112 crosses the boundary between the game board 80 and the base portion 361 of the reinforcing plate 350.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 18, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 801 provided in the main controller 162 incorporates a main control circuit 802 and a power failure monitoring circuit 803. An MPU 811 is mounted on the main control circuit 802. The MPU 811 includes a ROM 812 that stores various control programs executed by the MPU 811 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 812 is executed. A RAM 813 and various circuits such as an interrupt circuit, a timer circuit, and a data input / output circuit are incorporated.

  The RAM 813 is configured such that even after the power of the pachinko machine 10 is shut off, the data storage holding power is supplied from the power / fire control board 821 provided in the power / fire control device 243 to hold the data.

  An input / output port is connected to the MPU 811 via a bus line including an address bus and a data bus. Connected to the input side of the main control circuit 802 are a power failure monitoring circuit 803 provided on the main control board 801, a payout control board 822 provided on the payout control device 242, and other switches not shown. In this case, a power / fire control board 821 is connected to the power failure monitoring circuit 803, and power is supplied to the main control circuit 802 via the power failure monitoring circuit 803.

  On the other hand, a power failure monitoring circuit 803, a payout control board 822 and a relay terminal board 823 are connected to the output side of the main control circuit 802. Various commands such as a prize ball command are output to the payout control board 822. Various commands and the like are output from the main control circuit 802 to the sound lamp control board 824 provided in the sound lamp control device 143 via the relay terminal plate 823.

  The power failure monitoring circuit 803 relays the main control circuit 802 and the power supply / launch control board 821 and monitors the DC stable 24 volt power source that is the maximum power output from the power supply / fire control board 821.

  The payout control board 822 controls payout of prize balls and rental balls by the payout device 224. The MPU 831 that is an arithmetic unit includes a ROM 832 that stores a control program executed by the MPU 831, fixed value data, and the like, and a RAM 833 that is used as a work memory or the like.

  Similar to the RAM 813 of the main control circuit 802, the RAM 833 of the payout control board 822 is configured such that the data storage holding power is supplied from the power supply / launch control board 821 even after the power supply of the pachinko machine 10 is shut off. It has become.

  An input / output port is connected to the MPU 831 of the payout control board 822 via a bus line including an address bus and a data bus. On the input side of the payout control board 822, a main control circuit 802, a power / fire control board 821, and a backpack board 829 are connected. The main control circuit 802 and the back pack substrate 829 are connected to the output side of the payout control substrate 822.

  The power / fire control board 821 includes a power supply unit and a fire control unit. The power supply unit supplies necessary operating power to the main control circuit 802, the payout control board 822, and the like through a path indicated by a double line arrow. The launch control unit is responsible for launch control of the game ball launch mechanism 110 according to the operation of the game ball launch handle 41 by the player, and the game ball launch mechanism 110 is driven when predetermined launch conditions are met. .

  The sound lamp control board 824 controls the various lamp units 24 to 26, the speaker unit 27, and the display control device 825. The MPU 841 that is an arithmetic unit includes a ROM 842 that stores a control program executed by the MPU 841, fixed value data, and the like, and a RAM 843 that is used as a work memory or the like.

  An input / output port is connected to the MPU 841 of the sound lamp control board 824 via a bus line including an address bus and a data bus. The main control circuit 802 is connected to the input side of the sound lamp control board 824 by relaying to the relay terminal plate 823. Based on various commands output from the main control circuit 802, various lamp units 24 to 25, speakers The unit 27 and the display control device 825 are controlled. The display control device 825 controls the symbol display device 94 based on a display command input from the sound lamp control board 824.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  By configuring the game board 80 to be detachable from the resin base 60, maintenance work and model change of the game board 80 are facilitated. In particular, by making the game board 80 detachable from the front side of the resin base 60, it is possible to facilitate the work compared to a configuration in which the game board is attached and detached from the back side of the resin base. Assuming a configuration in which the game board is attached and detached from the back side of the resin base, it is necessary to attach and detach the game board with the inner frame opened. In this case, for example, by holding the movement of the inner frame by hand so that the inner frame does not move, the game board can be mounted smoothly. However, the work can be complicated when the inner frame is pressed by hand for the purpose of facilitating the work of attaching and detaching the game board. In this regard, as shown in the above embodiment, if the game board 80 can be attached and detached while the inner frame 13 is closed with respect to the outer frame 11, the inner frame 13 is moved by a pushing operation force or the like. Can be avoided. This eliminates the need for preliminary work such as pressing the inner frame 13 by hand when attaching or detaching the game board 80, and can contribute to facilitating the work. Since the opening / closing operation of the back pack unit 15 can be omitted, the work procedure can be simplified.

  Thus, in the configuration in which the game board 80 is attached from the front side of the resin base 60, the positional accuracy (for example, the position in the front-rear direction) of the front of the game board is compared with the configuration in which the game board is attached from the back side of the resin base. It is assumed that it is difficult to improve accuracy. In this regard, in the present embodiment, the game board 80 is pushed to the front side by the biasing part 415 of the locking device 400 and the operation part 446 is brought into contact with the front surface of the game board 80 to the front of the game board 80. By restraining the movement of the game board 80, it is possible to position the front surface of the game board 80 as a target. As a result, the positional accuracy on the front surface of the game board 80 is easily increased as compared with the configuration in which the front and rear positioning is performed with the back surface of the game board 80 as a reference.

  As described above, by increasing the positional accuracy of the front surface of the game board 80, the landing position of the game ball launched from the game ball launching mechanism 110 with respect to the guide rail 100 is prevented from varying. Thereby, the rampage of the game ball when passing through the guide rail 100 is suppressed, which contributes to smooth guidance to the game area PE. In particular, in a configuration in which the guide rail 100 stands up from the front surface of the game board 80, when a game ball lands on the leading end side of the guide rail 100, the load at the time of collision increases, and the root portion of the guide rail 100 (details) It is assumed that deformation or the like is likely to occur in the fixing pin 102a and the like. This is not preferable because it can hinder smooth guidance of the game ball. In this regard, by improving the front-rear position accuracy of the front surface of the game board 80, the landing position of the game ball can be prevented from varying back and forth, and the above-described inconvenience can be suitably avoided.

  Further, in the present embodiment, the inner frame 13 is pivotally supported by the outer frame 11 so as to facilitate the opening operation. However, in such a configuration, although it is possible to contribute to improvement of workability, there is a concern that the improvement of the position accuracy described above is hindered by the inner frame 13 (specifically, the resin base 60) being bent or twisted. Is done. In this regard, the deformation is suppressed by disposing the reinforcing plate 350 so as to extend from the rotation base end portion of the resin base 60 to the rotation tip end portion. In particular, the reinforcing plate 350 is arranged along the front opening part (specifically, the lower end edge) of the game board housing portion 61 to compensate for the strength that tends to decrease in the vicinity of the opening part, so that the above-described reinforcing effect can be suitably enjoyed. It is possible to do.

  The game ball launching mechanism 110 and the lock device 400 are disposed (specifically installed) on the reinforcing plate 350, whereby the game ball launching mechanism 110 (specifically the launch rail 112) and the game board 80 (specifically the guide rail). 100) and the accuracy of the relative position of the game ball launched from the launch rail 112 can be improved. Therefore, smooth guidance of the game ball by the guiding means can be expected.

  In the configuration in which the game board 80 is mounted from the front, a game board housing part 61 that is recessed rearward is provided, and the reinforcing plate 350 is formed in a crank shape along the plate installation part 69, the lower side wall part 66, and the opposing plate part 62. By doing so, the front and back positions of the front surface of the game board 80 (specifically, the guide rail 100) and the launch rail 112 can be suitably aligned while improving the strength of the reinforcing plate 350, and the accuracy improvement effect is more remarkable. Can be.

  In particular, the game ball launching mechanism 110 is in contact with the front surface of the reinforcing plate 350 (specifically, the base portion 361) in the vicinity of the end of the launch rail 112 that is closer to the guide rail 100. Thereby, the positional accuracy improvement effect mentioned above can be made more remarkable.

  By bringing the base plate 114 and the reinforcing plate 350 of the game ball launching mechanism 110 into surface contact, the stability of the game ball launching mechanism 110 is improved. In particular, the base portion 361 of the reinforcing plate 350 has a long shape extending in the left-right direction, and the game ball launching mechanism 110 (specifically, the base plate is described in detail) by arranging the launch rail 112 and the solenoid 111 side by side in this longitudinal direction. 114) also has a horizontally long shape. As a result, the contact area between the base portion 361 and the base plate 114 is expanded while suppressing the useless expansion of the occupied area, and the above-described stability effect is further improved.

  The entrance portion 104 of the guide rail 100 is disposed at a position near the lower end of the game board 80, and the lock device 400, the reinforcing plate 350, and the game ball launching mechanism 110 are gathered at a position near the lower end. . Thereby, the accuracy of the relative position between the entrance portion 104, specifically the specific part SP, and the game ball launching mechanism 110 can be made favorable.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (1) In the above embodiment, the reinforcing plate 350 as the “supporting frame reinforcing member” is fixed to the resin base 60 as the “supporting frame” using the screws 391. However, the fixing method of the reinforcing plate 350 is as follows. It is not limited to this. For example, it is possible to fix using an adhesive, or it is possible to provide a locking portion that locks the other on at least one of the resin base 60 and the reinforcing plate 350, and fix by the same locking portion. .

  Further, it is only necessary that the reinforcing plate 350 can be positioned with respect to the resin base 60, and it is not always necessary to employ the plate installation portion 69.

  (2) In the above embodiment, the plate-shaped reinforcing plate 350 is employed as the “support frame reinforcing member”. The support frame reinforcing member does not necessarily have a plate shape, and may be, for example, a rod shape or a block shape. In particular, when a block-shaped configuration is adopted, it is preferable to form the support frame reinforcing member in a hollow shape to suppress an increase in weight while ensuring strength.

  (3) In the above embodiment, the front and rear positions of the game board 80 are defined by the lock device 400 as “positioning means”, but the present invention is not limited to this. For example, it is possible to adopt a configuration in which the vertical position and the horizontal position of the game board 80 are defined by positioning means. Hereinafter, a specific example will be described with reference to FIG. FIG. 19A is a schematic view showing a modification of the positioning means.

  In the above embodiment, the positioning protrusion 79 is formed on the resin base 60, and the left and right positions of the game board 80 are defined by the positioning protrusion 79. It is also possible to provide this positioning projection on the reinforcing plate. Specifically, in the facing portion 901 of the reinforcing plate 900, a through hole 902 is formed at a position behind the through hole 91 of the game board 80, and the positioning pin 910 is inserted into the through hole 902 and fixed. Is possible.

  As described above, the left and right positions of the game ball launch mechanism 110 (specifically, the launch rail 112) are defined by the reinforcing plate. Therefore, by defining the left and right positions of the game board 80 with the positioning pins 910 of the reinforcing plate 900, the accuracy of the relative position (left and right position) between the game ball launching mechanism 110 and the game board 80 can be preferably improved. .

  (4) In the above embodiment, the lock device 400 as the “positioning means” is fixed to the resin base 60 in a state where the lock device 400 is installed on the reinforcing plate 350. However, this can be changed as follows. It is. In other words, the lock device can be fixed to the reinforcing plate, and the locking device can be installed and fixed to the reinforcing plate. Hereinafter, a specific example thereof will be described with reference to FIG. FIG. 19B is a schematic view showing a modification of the mounting structure of the locking device.

  As shown in FIG. 19B, a through hole 922 that penetrates in the front-rear direction is provided in the facing portion 921 of the reinforcing plate 920. The through-hole 922 is formed to have a size that allows the screw 418 to be inserted, and a plate surface opposite to the game board 80 in the facing portion 921, that is, a plate surface on the facing plate portion 62 side of the resin base 60, A nut 925 is fixed so as to communicate with the through hole 922 (specifically, welded). The locking device 400 is fixed to the reinforcing plate 920 by screwing screws 418 into the nuts 925. By fixing the locking device 400 to the reinforcing plate 920 in this manner, it is possible to contribute to further improvement in positioning accuracy.

  (5) In the above embodiment, the reinforcing plate 350 is bent along the plate installation portion 69, the lower side wall portion 66, and the opposing plate portion 62 to form a crank shape as a whole. do not have to. However, paying attention to the point that the resin base 60 is reinforced by the reinforcing plate, the strength can be improved by making the cross section of the reinforcing plate (the cross section orthogonal to the longitudinal direction of the reinforcing plate) L-shaped or U-shaped. desirable. As described above, when the strength is improved, it is assumed that it is difficult to suppress the expansion of the area occupied by the reinforcing plate. In this regard, if the reinforcing plate is bent along the front surface of the resin base 60 as shown in the above embodiment, such a disadvantage can be suitably eliminated, and a practically preferable configuration can be realized.

  (6) In the above embodiment, the game board 80 is attached from the front of the pachinko machine 10 to the resin base 60 as the “support frame”. However, the game board 80 is attached from the rear to the support frame. It is also possible. In this case, the front and back positions of the game board are defined by bringing the game board into contact with the back surface of the reinforcement plate, and the game ball launching mechanism (specifically, the base plate) is brought into contact with the front surface of the reinforcement plate. By defining the front and rear positions of the game ball launching mechanism, the accuracy of the relative position between the game board and the game ball launching mechanism can be suitably increased.

  (7) In the above embodiment, the gaming board 80 is configured to abut on the operation unit 446 of the locking device 400 from the back of the pachinko machine 10 to define the front and rear positions of the gaming board 80. It is good also as a structure which positions in the front-back direction of the game board 80 when the game board pushed by the locking device contacts the opposing part 381 of the reinforcement plate 350. In other words, the game board 80 can be positioned not on the front surface of the game board 80 but on the back surface of the game board 80 as a target. However, when such a change is made, it is assumed that the positional accuracy of the relative position between the game ball launching mechanism 110 and the front surface of the game board 80 is likely to decrease due to variations in the thickness of the game board 80 and the like. Is done. Therefore, it is desirable to position the front of the game board 80 as a target.

  (8) In the above embodiment, the base plate 410 of the locking device 400 is fixed to the resin base 60. However, the present invention is not limited to this. For example, the shaft pin 420 and the operation lever 440 can be fixed to the resin base.

  Note that the locking device 400 does not necessarily need to be unitized, and each configuration can be individually attached. In this case, a practically preferable configuration can be realized by attaching at least the operation lever to the reinforcing plate 350.

  (9) In the above embodiment, the solenoid 111 as the “launching unit”, the firing rail 112 as the “launching rail unit”, etc. are fixed to the base plate 114 as the “base body”, thereby unitizing the configuration related to the launching. did. The base plate 114 is installed on the reinforcing plate 350 so that the firing rail 112 is positioned with respect to the reinforcing plate 350. However, the present invention is not limited to this. For example, the firing rail 112 may be directly installed on the reinforcing plate 350 without using the base plate 114.

  (10) In the above embodiment, the game ball launching mechanism 110 (specifically, the launch rail 112) is positioned at two locations separated in the longitudinal direction of the reinforcing plate 350, that is, two locations on the left and right. It is also possible to perform positioning at two locations, upper and lower. However, when such a change is made, it is assumed that the reinforcing plate 350 is expanded vertically. When the reinforcing plate is formed so as to connect the rotating base end portion and the rotating tip end portion of the resin base 60, the reinforcing effect can be preferably exerted. On the other hand, when the reinforcing plate extends in the rotating central axis direction, There is a concern that the demerit due to the weight increase becomes larger than the merit due to the reinforcing effect. Therefore, it is desirable to position the game ball launching mechanism 110 at a plurality of positions on the left and right sides.

  In addition, the base plate 114 and the base portion 361 of the reinforcing plate 350 are brought into surface contact, and the contact range is expanded in the longitudinal direction (left and right direction) compared to the short direction (vertical direction) of the reinforcing plate 350. It is also possible to change the contact range so that the contact range expands in the short direction as compared with the longitudinal direction of the reinforcing plate 350.

  (11) In the above embodiment, the reinforcing plate 350 is fastened together with the plate member 281 together with the resin base 60. However, it is also possible to have a structure in which both are screwed independently.

  (12) In the above embodiment, the front surface of the base plate 114 of the game ball launch mechanism 110 (specifically, the launch rail 112) and the front surface of the game board 80 are flush with each other. It is not limited to this. At least interference between the trajectory of the game ball fired from the launch rail 112 and the lower edge of the game board may be avoided. For example, the launch rail 112 may be configured to be positioned in front of the front surface of the game board.

  (13) In the above embodiment, the operation unit 446 of the lock device 400 is rotated to switch between the locked state and the unlocked state, but this is changed and the operation unit is slid in a specific direction. It is good also as a structure which switches a locked state and an unlocked state.

  (14) The arrangement of the locking device 400 is arbitrary. For example, the game board 80 can be arranged close to the rotation base end. However, if the front door frame 14 is arranged close to the rotation base end side, it may be difficult to secure a work space for rotating the lock device 400. Therefore, it is preferable that the front door frame 14 be arranged close to the rotating front end side of the front door frame 14, that is, the rotating front end side of the game board 80.

  (15) In the above embodiment, when the operation amount of the operation unit 446 reaches a predetermined amount, the pusher 430 that pushes the game board 80 protrudes at a stretch. However, this can be changed as follows. is there. That is, the protrusion amount of the pusher 430 may be gradually increased as the operation amount of the operation unit 446 increases.

  (16) In the above embodiment, the pusher 430 pushes the game board 80 when the operation unit 446 is rotated from the unlock position to the position where it comes into contact with the front surface of the game board 80. You may change as follows. In other words, the pusher 430 may push the game board 80 before the operation unit 446 rotates from the unlock position to a position where the operation part 446 contacts the front surface of the game board 80. However, when such a change is made, it is assumed that the operation of the operation unit 446 is likely to be hindered by the game board 80 pushed by the pusher 430. This can be a factor that makes it difficult to perform the switching operation of the lock device 400. In this regard, as shown in the above embodiment, if the pusher 430 pushes the game board 80 after the operation part 446 has been rotated to a position where it is not obstructed by the game board 80, the operation part 446 and the game board will certainly be used. Although friction occurs between the control unit 80 and the control unit 80, it is possible to avoid the inconvenience that the operation unit 446 can be used by the game board 80 (specifically, the inner surface of the insertion unit 92).

  (17) In the above embodiment, when the lock device 400 is in the unlocked state, the longitudinal direction of the operation unit 446 and the direction orthogonal to the rotation center axis of the game board 80 are configured to match. It is not limited to this. For example, the longitudinal direction of the operation unit 446 may be different from the direction orthogonal to the rotation center axis of the game board 80. However, in this case, since the game board 80 is configured to rotate, it is necessary to set a large passage gap of the operation unit 446 in the insertion unit 92. This is a factor that keeps the portion of the operation unit 446 that contacts the game board 80 away from the base 441 of the operation lever 440. That is, it is possible to reduce the allowance for the game board 80 and increase the stress applied to the operation lever 440. Therefore, desirably, in the unlocked state, the longitudinal direction of the operation unit 446 may be aligned with the direction orthogonal to the rotation center axis of the game board 80.

  (18) In the above embodiment, the operation portion 446 of the operation lever 440 is configured to be symmetric with respect to the central axis of the base portion 441. However, the symmetric shape is not necessarily required, and the central axis is sandwiched. However, the shape may be different on both sides.

  In addition, the operation unit 446 is configured to contact the front surface of the game board 80 on both upper and lower sides with the base portion 441 interposed therebetween, but this is changed so that one of the upper and lower sides of the base portion 441 contacts the front surface of the game board 80. A configuration is also possible. For example, the operating lever 440 can be deformed from a T-shape to an L-shape, and the number of contact points with the front surface of the game board 80 can be reduced.

  (19) In the above embodiment, the operation levers 440 have the same shape, but the insertion portions 92 of the game board 80 have different shapes. However, this is changed and the operation levers 440 are similar to each other. The shape of each insertion portion 92 may be unified.

  (20) In the above embodiment, the rotation range of the operation lever 440 is limited to about 90 °, and the lock state and the unlock state can be switched within the range. Is not limited to this. For example, it may be 180 ° or 360 °.

  In addition, it is configured to be switched to the locked state by rotating clockwise from the unlocked state, and switched to the unlocked state by rotating counterclockwise from the locked state, but this has been changed as follows: May be. That is, it is good also as a structure by which switching with a locked state and an unlocked state is made | formed by rotation operation to the same direction. For example, it is possible to adopt a configuration in which the locked state and the unlocked state are switched every time it is rotated 180 ° clockwise. Thereby, it is possible to easily secure the allowance between the game board 80 and the operation unit 446 shown in the modified example (17).

  (21) In the above embodiment, the opposing plate portion 62 has an annular shape (specifically, a rectangular frame shape), but the opposing plate portion only needs to have a flat plate shape facing the back of the game board 80, The outer shape does not necessarily have to be annular. For example, the opposing plate portion may be formed in a long plate shape extending over the left frame portion 13c and the right frame portion 13d of the inner frame 13.

  In addition, although the opposing plate portion 62 is configured to have irregularities such as ribs and dents for the purpose of reinforcement, member attachment, etc., it is also possible to adopt a configuration without such irregularities.

  (22) In the above embodiment, the game board accommodating part 61 is configured by the opposing plate part 62 and the peripheral wall part 63, but the game board accommodating part 61 is not essential. It is only necessary to have a configuration corresponding to at least the counter plate portion 62, and the peripheral wall portion 63 can be omitted.

  (23) In the above embodiment, the positioning protrusions 79 that define the left and right positions of the game board 80 are disposed between the left and right lock apparatuses 400 that fix the game board 80. The relationship is arbitrary, and it is not necessary to place the positioning protrusion 79 between the two locking devices 400. Further, although the positioning projection 79 is arranged close to the left lock device 400, the positioning projection 79 can be arranged close to the right lock device 400.

  (24) In the above embodiment, in the process of placing the game board 80 in the mounting completion position, the operation part 446 of the locking device 400 first enters the insertion part 92 of the game board 80, and then the positioning projection 79 is moved to the game board 80. However, it is also possible to change the configuration so that the operation portion 446 enters the insertion portion 92 after the positioning projection 79 enters the through hole 91. However, in this case, since the positioning projection 79 tries to enter the through-hole 91 in a state where the left and right positions of the game board 80 are largely varied, the positioning projection 79 does not fit into the through-hole 91 and the rear surface of the game board 80 or the like. There is a concern about the collision. This is not preferable because it may cause the positioning projection 79 to be deformed and cause a decrease in positioning accuracy. Therefore, preferably, as shown in the above embodiment, first, the positioning protrusion 79 penetrates with the operation unit 446 and the insertion unit 92 suppressed the rough displacement of the game board 80 and with a certain positioning target. A configuration that enters the hole 91 is preferable.

  (25) In the above-described embodiment, the positioning projection 79 has a cylindrical shape. However, the positioning projection can also have a prismatic shape. Further, although the diameter of the tip portion of the positioning protrusion 79 is reduced, this can be omitted.

  (26) In the above embodiment, the positioning protrusions 79 that define the left and right positions of the game board 80 are arranged behind the outer rail 102 of the game board 80, but this is changed to replace the positioning protrusions 79 with the pachinko machine 10. It is also possible to arrange the inner side of the outer rail 102 or the outer side of the outer rail 102 in a front view. However, even when the arrangement of the positioning protrusions 79 is changed as described above, it is preferable that the positioning protrusions 79 be arranged as close as possible to the specific part SP.

  (27) In the above embodiment, the entrance portion 104 of the guide rail 100 is arranged near the lower end of the game board 80, but the entrance portion 104 may be arranged near the upper end of the game board 80. However, when such a change is made, it is assumed that the variation in the landing position of the game ball is increased by increasing the interval between the entrance portion 104 and the game ball launching mechanism 110. In this case, even if the position variation is suppressed by the positioning protrusion in the vicinity of the entrance portion 104, the variation in the launch of the game ball becomes dominant, and there is a concern that the benefits of the landing position stabilization function by the positioning protrusion cannot be fully enjoyed. Is done. Therefore, it is desirable that the entrance portion 104 of the guide rail 100 be disposed close to the lower end of the game board 80, that is, the game ball launching mechanism 110.

  In addition, although the entrance portion 104 of the guide rail 100 is arranged near the center of the game board 80, for example, the entrance portion 104 can be arranged near the end of the game board 80 on the rotation base end side. In this case, the game ball launching mechanism 110 may be arranged close to the same side.

  (28) In the above embodiment, the game ball launched from the game ball launching mechanism 110 crosses the lower end edge of the game board 80, that is, the front of the lower wall portion 66 obliquely. In other words, the entrance portion 104 of the guide rail 100 and the tip portion of the firing rail 112 in the game ball launching mechanism 110 face each other with the lower wall portion 66 interposed therebetween. By changing this, the entrance portion 104 of the guide rail 100 and the tip portion of the launch rail 112 in the game ball launching mechanism 110 are arranged vertically with the lower wall portion 66 interposed therebetween, and the game ball launched from the game ball launching mechanism 110 However, it may be configured to vertically traverse the lower edge of the game board 80, that is, the lower wall portion 66 of the inner frame 13. However, in this case, there is a possibility that the game ball is displaced to the inner rail 101 side, and it may be difficult to specify the landing position of the game ball. Therefore, it is desirable to tilt the flight direction of the game ball toward the outer rail 102 even slightly.

  (29) In the above embodiment, the outer rail 102 has an arc shape, and the tangent TL at the specific portion SP of the outer rail 102 is set in the same direction as the rail direction of the launch rail 112, so that the impact at the time of landing on the game ball And smooth guidance along the outer rail 102 was made possible. You may change this as follows. That is, instead of making the entire outer rail arc-shaped, a part including the specific portion SP may extend in the same direction as the rail direction of the firing rail 112. Thereby, the same effect as the above-described embodiment can be obtained.

  (30) In the above embodiment, the rail support member 107 is attached to the through hole 91 through which the positioning protrusion 79 is inserted. However, the rail support member 107 can be omitted. It is also possible to attach the rail support member 107 using a hole other than the through hole 91 or the like.

  (31) Instead of the through hole 91 penetrating in the thickness direction of the game board 80, a hole or a recess not penetrating in the thickness direction of the game board 80 may be used. Furthermore, although the through hole has a long hole shape that is vertically expanded and allows the positioning protrusion 79 to move in the vertical direction, the present invention is not limited to this. For example, the inner shape of the through hole 91 can be formed in accordance with the outer shape of the positioning protrusion 79, and a vertical positioning function can be given to the through hole 91 and the positioning protrusion 79. However, when such a change is made, it is assumed that a burden generated on the positioning projection 79 becomes large and the positioning projection 79 is likely to be deformed. This is not preferable because it may cause a decrease in positioning function. Therefore, it is desirable that the through hole 91 be formed so that a gap that allows a vertical position variation of the game board 80 is formed between the through hole 91 and the positioning projection 79.

  (32) In the above-described embodiment, the guide rail 100 is configured by the inner rail 101 and the outer rail 102. However, both the rails are not necessarily required. It is only necessary to have a rail corresponding to at least the outer rail 102. Moreover, it is not necessary to provide the inner rail 101 and the outer rail 102 as separate bodies, and it is also possible to provide both of them integrally (for example, integrally molding).

  (33) In the above embodiment, the game ball is configured to land on the specific part SP of the outer rail 102 when the operation amount of the game ball launch handle 41 is equal to or greater than the first specified amount. However, it is also possible to adopt a configuration in which the game ball lands on the specific part SP of the outer rail 102 when the operation amount becomes equal to or greater than the second specified amount. If the amount of operation of the game ball launch handle 41 increases, the launch speed of the game ball also increases. If the game ball firing speed increases, for example, to a level that reaches the return rubber, it is assumed that the impact when landing on the outer rail 102 also increases. At least, it is possible to easily contribute to improving the durability of the outer rail 102 by suppressing the variation in the collision position of the game balls launched at such a high firing speed.

  (34) Other types of pachinko machines different from the above embodiment, for example, a pachinko machine in which the electric accessory is released a predetermined number of times when a game ball enters the specific area of the special device, or a game ball in the specific area of the special device The present invention can also be applied to a pachinko machine that generates a right if a player enters, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and other gaming machines.

<Invention Group Extracted from the Embodiments>
Hereinafter, the features of the invention group extracted from the above-described embodiment will be described while showing effects and the like as necessary. In the following, for ease of understanding, the corresponding configuration in the above embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Features 1. A game board (game board 80) in which a game area (game area PE) is formed on the front side;
Guiding means (guidance rail 100) that forms a wall standing up from the front of the gaming board and guides the gaming ball to the gaming area by moving the gaming ball along the wall surface;
A support frame (resin base 60 of the inner frame 13) for removably supporting the game board;
A support frame reinforcing member (reinforcement plate 350) fixed to the support frame and disposed along the lower end of the game board;
