JP 2004-209154 A

  By the way, in the pachinko machine as described above, as the liquid crystal unit is shared among a plurality of models, the mounting part of the liquid crystal unit on the pachinko machine side is also shared. This has limited the design of pachinko machines. This has become a factor that all pachinko machines have a uniform design regardless of the model, making it difficult to appeal the novelty of the design to the players. In addition, changing the mounting position of the liquid crystal unit requires changing the design of the substrate case of the liquid crystal unit or the mounting part of the pachinko machine, which increases the manufacturing cost of the pachinko machine even if the liquid crystal unit is used as a common part. There was a problem that.

  The present invention has been made to solve the above-described problem, and provides a board case that can be mounted at a low cost while the case main body containing a control board for executing a game is stored as a common component. The purpose is to provide.

  A bullet ball game machine of the present invention includes a case main body that houses a control board that performs game execution processing, and the case main body is attached to the back side of a game board included in the game machine main body. A locking member for locking to the back surface of the gaming machine main body is detachably attached to the case main body so as to be removable from the gaming machine main body.

  In addition, it is preferable that the case main body accommodates a liquid crystal display and a liquid crystal control board that performs display control of the liquid crystal display.

  Further, the locking member protrudes substantially parallel to the board surface of the gaming board, and a positioning member inserted into an insertion hole formed in the gaming machine main body, and the positioning member protrudes in the opposite direction, and the game The case body is configured by fitting the positioning member into the insertion hole and then rotating the positioning member side as a fulcrum to insert the positioning member into the insertion hole. When the fitting member is fitted into the fitting hole, it is preferably attached to the gaming machine body.

  The case body includes a first rail and a second rail having a width dimension different from the first rail, and the positioning member includes a rail groove that can be attached to the first rail, The fitting member preferably includes a rail groove to which the second rail can be attached.

  Further, the positioning member protrudes upward, the fitting member protrudes downward, and the positioning member includes a temporary fixing portion that is engaged with a concave portion or a convex portion formed in the gaming machine main body. Is preferred.

  The board case of the present invention has a locking member that is detachably attached to the back surface of the gaming machine main body so that it can be detached from the gaming machine main body, so that only the shape of the locking member is changed. The attachment position of the case body can be changed, and the attachment position can be changed inexpensively while using the case body as a common component.

  In addition, the case body contains a liquid crystal display and a liquid crystal control board that controls the display of the liquid crystal display, so it is possible to use a relatively expensive liquid crystal display as a common component compared to other components. Thus, the manufacturing cost of the gaming machine can be reduced.

  The case main body is attached to the gaming machine main body by inserting the positioning member into the insertion hole of the gaming machine main body and then rotating the positioning member side about the fulcrum so as to fit the fitting member into the fitting hole. Therefore, it becomes possible to attach the board case efficiently, and the manufacturing cost of the ball game machine can be reduced.

  In addition, since the shape of the attachment portion of the positioning member to the case main body and the attachment portion of the fitting member to the case main body are different, the positioning member and the fitting member can be prevented from being erroneously attached to the case main body. Work for assembling the case can be performed efficiently.

  Further, the positioning member protrudes upward, the fitting member protrudes downward, and the positioning member includes a temporary fixing portion that is locked to a concave portion or a convex portion formed in the gaming machine main body. It is possible to temporarily fix the substrate case in a suspended state, and the substrate case can be easily attached and detached even if the weight in the substrate case increases.

  As shown in FIG. 1, the pachinko machine 10 includes a main body (game machine main body) 10a. The main body 10 a includes a game board 11. On the front surface of the game board 11, a game area 11a surrounded by a known rail is provided. The game area 11 a is provided with a symbol display device 12, a start port 13, a through chucker 14, an attacker 15, and an out port 16. Although not shown, obstacle nails, windmills, and the like are provided.

  The symbol display device 12 includes a liquid crystal display 12a. The pachinko ball launched into the game area 11 a enters one of the start port 13, the through chucker 14, and the out port 16. When a pachinko ball is detected at the start port 13, a change display of the symbol is performed on the liquid crystal display 12a, and whether or not a big hit is displayed depending on the combination of the stopped symbols. When the jackpot is obtained, the attacker 15 is opened a plurality of times. When a pachinko ball is detected by the through chucker 14, the pair of movable blades provided at the start port 13 rotate from the closed position to the open position, and the pachinko ball easily enters the start port 13. When a pachinko ball is detected as a pachinko ball in either the start port 13 or the attacker 15, the prize ball is paid out to the tray 18 through the payout port 17.

  As shown in FIG. 2, the pachinko machine 10 includes a game board unit 20. The game board unit 20 includes a game board 11, a front frame 21, a back mechanism plate 22, a liquid crystal unit 23, and a protective cover 24.

  The front frame 21 is attached to the front surface of the game board 11. The front frame 21 defines a game area 11a by rails on the inner side of the front frame 21, and further forms a ball passage on the game board 11 for launching a pachinko ball in the game area 11a. At the four corners of the front frame 21, there are provided rotatable levers 25 that are operated when the back mechanism plate 22 is connected. The lever 25 is formed with a hook (not shown). Locking portions 26 for locking the hooks of the lever 25 are formed at the four corners of the back mechanism plate 22. When the lever 25 is rotated from the horizontal state to the vertical state, the hook of the lever 25 is locked to the locking portion 26 and the back mechanism plate 22 and the front frame 21 are connected. When the back mechanism plate 22 and the front frame 21 are connected, the game board 11 is sandwiched between the front frame 21 and the back mechanism plate 22. A plurality of ribs are formed on the front surface of the back mechanism plate 22, and a ball passage is formed between the back mechanism plate 22 and the game board 11 by the ribs. Pachinko balls that have won the starting port 13 and the attacker 15 are guided to this ball path and collected at the island facility.

  The liquid crystal unit 23 is detachably attached to the back surface of the back mechanism plate 22. When the liquid crystal unit 23 is attached to the back mechanism plate 22, the front surface is exposed from the opening 11 b of the game board 11. The protective cover 24 is attached to the back surface of the back mechanism plate 22 via a substantially vertical shaft 24a. Thereby, the protective cover 24 is rotatable in the horizontal direction. When the protective cover 24 is closed, the liquid crystal unit 23, the harness, the substrate, and the like are covered, and the pachinko machine 10 that has fallen from an island facility or a storage tank (not shown) is in contact with these to prevent the pachinko machine 10 from malfunctioning. .

  As shown in FIGS. 3 and 4, the liquid crystal unit 23 includes a substrate case 30, a liquid crystal display 12a, and a display control board 12b (see FIG. 7) that performs display control of the liquid crystal display 12a. The substrate case 30 includes a case body 31. The case main body 31 is formed in a box shape with a transparent resin. The case body 31 includes a front cover 31a and a rear cover 31b. The front cover 31a and the rear cover 31b are connected by claw engagement. The case body 31 houses a liquid crystal display 12a and a display control board 12b. A pair of positioning members 32 are detachably attached to the attachment portion 33 on the upper surface of the case body 31. A pair of fitting members 34 are detachably attached to the attachment portion 35 on the lower surface of the case body 31. The positioning member 32 protrudes upward, and the fitting member 34 protrudes downward. The positioning member 32 and the fitting member 34 are formed of a transparent resin like the case body 31.

  As shown in FIG. 5, the positioning member 32 includes a substantially rectangular plate-like base 40 and a substantially prismatic insertion portion 41 protruding upward from the base 40. Locking claws 42 protruding forward are provided on both side surfaces of the base 40. As for the latching claw 42, the base end part is continued in the rear end side of the base 40, and the front-end | tip part has the spring property in the left-right direction.

  A linear rail groove 40a is formed on the bottom surface of the base 40 along the front-rear direction. The rail groove 40a is inserted into a rail (first rail) 33c (see FIG. 4) formed in the attachment portion 33. When the positioning member 32 is slid forward with the rail groove 40a inserted into the rail 33c, the locking claw 42 is guided to the locking hole 33a formed in the mounting portion 33. Thereby, positioning and attachment to the case main body 31 of the positioning member 32 become easy.

  As shown in FIG. 6, the locking claw 42 is inserted into the locking hole 33a. The locking claw 42 inserted into the locking hole 33 a is locked to a claw locking portion 33 b formed in the attachment portion 33. Thereby, the positioning member 32 is fixed to the case main body 31. In order to remove the positioning member 32 from the case main body 31, the locking claws 42 are pushed in a direction in which they approach each other. By this pushing, the locking claw 42 and the claw locking portion 33b are unlocked, and the positioning member 32 can be removed.

  As shown in FIGS. 7 to 9, the insertion portion 41 is inserted into the insertion hole 22 a formed above the back mechanism plate 22 on the back surface. Insertion of the insertion portion 41 into the insertion hole 22a is performed with the liquid crystal unit 23 tilted (state shown in FIG. 8). A convex portion 22b is formed below the insertion hole 22a so as to project to the back side of the back mechanism plate 22. On the other hand, a concave portion (temporary fixing portion) 41 a is formed on the front surface of the insertion portion 41. When the insertion portion 41 is inserted into the insertion hole 22a, the convex portion 22b enters the concave portion 41a (state shown in FIG. 9). The convex portion 22b is bent downward. For this reason, when inserting the insertion part 41 in the insertion hole 22a, the recessed part 41a is guided by the convex part 22b along the bending direction of the convex part 22b.

  As shown in FIG. 10, the fitting member 34 includes a rectangular plate-like base 50 and a fitting portion 51 protruding downward from the base 50. The base 50 has the same shape as the base 40, and locking claws 52 configured in the same manner as the locking claws 42 are provided on both side surfaces of the base 50.

  A linear rail groove 50a is formed on the bottom surface of the base 50 along the front-rear direction. The rail groove 50a is inserted into a rail (second rail) 35c (see FIG. 13) formed in the attachment portion 35 of the case body 31. When the fitting member 34 is slid forward with the rail groove 50a inserted into the rail 35c, the locking claw 52 is guided to the locking hole 35a formed in the mounting portion 35. Thereby, positioning and attachment to the case main body 31 of the fitting member 34 become easy. Similarly to the locking claw 42, the locking claw 52 is inserted into the locking hole 35a (see FIG. 13) and locked to the claw locking portion 35b (see FIG. 13). The removal method is the same as that of the positioning member 32. The width dimension L1 of the rail groove 40a is wider than the width dimension L2 of the rail groove 50a.

  As shown in FIG. 11 to FIG. 13, in addition to the width direction dimension L1 of the rail groove 40a and the width direction dimension L2 of the rail groove 50a, the width direction dimension L3 of the rail 33c is equal to the width direction of the rail 35c. It is wider than the dimension L5. In this way, the positioning member 32 is attached to the attachment portion 35 or the fitting member 34 is attached to the attachment portion 33 by making the width direction dimensions of the rail groove 40a and the rail groove 50a and the rail 33c and the rail 35c different. Can prevent errors such as mounting.

  As shown in FIGS. 14 and 15, a cylindrical recess 53 is formed at the tip of the fitting portion 51. A hole 54 penetrating in the front-rear direction is formed in the bottom surface of the recess 53. A fitting mechanism 55 is attached to the recess 53. The fitting mechanism 55 includes a fitting pin 56 and a fitting ring 57. The fitting pin 56 includes an operation knob 56a and a protrusion 56b protruding from the operation knob 56a. The protrusion 56b is formed in a cylindrical shape, and a plurality of steps are formed on the tip side.

  The fitting ring 57 includes a disk-shaped base 57a. A hole 57b is formed at the center of the base 57a. A plurality of fitting claws 57c are erected on one surface of the base 57a so as to surround the hole 57b. The fitting ring 57 is attached to the recess 53 by inserting the fitting claw 57 c into the hole 54. After the fitting claw 57c is inserted into the hole 54, the rear end edge of the fitting claw 57c is locked to the bottom surface of the recess 53, so that the fitting ring 57 is prevented from falling off the hole 54.

  A protrusion 56b of the fitting pin 56 is inserted through the hole 57b of the base 57a. The hole diameter of the hole 57b is slightly larger than the diameter of the protrusion 56b. For this reason, the fitting pin 56 can be slid back and forth while being inserted into the hole 57b. The fitting pin 56 has a push-in position (position shown in FIG. 14) slid forward (in the direction A in the figure) and a pull-out position (shown in FIG. 15) slid backward from the push-in position (in the direction B in the figure). Slide in position).

  The fitting pin 56 is slid back and forth using the operation knob 56a. The operation knob 56a is formed in a substantially disk shape. An arc-shaped depression is formed on the rear end surface of the operation knob 56a. The operator can easily slide the fitting pin 56 to the pushed-in position by pressing the depression with the tip of the finger. Further, in order to slide the fitting pin 56 to the pulling position, the fitting pin 56 may be pulled out rearward with the edge of the operation knob 56a being held.

  A cylindrical fitting protrusion 58 is formed on the back surface of the back mechanism plate 22 below the back mechanism plate 22. The front end surface of the fitting protrusion 58 is recessed one step, and a fitting hole 58a is formed on the bottom surface of the recessed portion. When the liquid crystal unit 23 is fixed to the back mechanism plate 22, the fitting protrusion 58 and the recess 53 are fitted so that the outer periphery of the fitting protrusion 58 contacts the inner periphery of the recess 53. At this time, the protrusion 56b of the fitting pin 56 and the fitting claw 57c of the fitting ring 57 enter the fitting hole 58a. When the fitting pin 56 is slid to the pushed-in position in this state, the fitting claws 57c are displaced in a direction to open each other. Thereby, the fitting claw 57c is locked to the peripheral wall of the fitting hole 58a, and the back mechanism plate 22 and the liquid crystal unit 23 are fixed. Further, when the fitting pin 56 is slid from the pushed-in position to the drawn-out position, the fitting claws 57c are displaced in a direction approaching each other by the restoring force. Accordingly, the engagement between the fitting claw 57c and the peripheral wall of the fitting hole 58a is released, and the liquid crystal unit 23 can be detached from the back mechanism plate 22.

  The insertion portion 41 is bent in a crank shape so that the center thereof is shifted to the right from the center of the rail groove 40a when viewed from the front. Further, the fitting portion 51 is inclined so that the center thereof is shifted to the right from the center of the rail groove 50a when viewed from the front. As a result, the insertion portion 41 is inserted into the insertion hole 22a, and the liquid crystal display 12a is disposed at the position of the opening 11b formed in the game board 11 when the recess 53 and the fitting protrusion 58 are fitted.

  Next, the flow of attaching the liquid crystal unit 23 to the back mechanism plate 22 and removing the liquid crystal unit 23 will be described. As shown in FIG. 16, first, the insertion portion 41 of the positioning member 32 is inserted into the insertion hole 22 a of the back mechanism plate 22 with the liquid crystal unit 23 tilted obliquely. When the insertion portion 41 is inserted into the insertion hole 22a, the concave portion 41b of the insertion portion 41 is locked to the convex portion 22b of the back mechanism plate 22. As a result, the liquid crystal unit 23 is suspended from the back mechanism plate 22, and the liquid crystal unit 23 is temporarily fixed to the back mechanism plate 22 and positioned. After temporarily fixing the liquid crystal unit 23 to the back mechanism plate 22, the lower end of the liquid crystal unit 23 is rotated toward the back mechanism plate 22 with the positioning member 32 side as a fulcrum.

  As shown in FIG. 17, when the liquid crystal unit 23 is rotated, the fitting projection 58 of the back mechanism plate 22 enters the recess 53 of the fitting member 34 and the recess 53 and the fitting projection 58 are fitted. In this state, when the fitting pin 56 is slid to the pushing position, the liquid crystal unit 23 is fixed to the back mechanism plate 22.

  When removing the liquid crystal unit 23 from the back mechanism plate 22, first, the fitting pin 56 is slid to the drawing position. After the fitting pin 56 is slid to the drawing position, the liquid crystal unit 23 is rotated with the positioning member 32 side as a fulcrum, and the engagement between the convex portion 22b of the back mechanism plate 22 and the concave portion 41b of the insertion portion 41 is released. . Thereafter, when the insertion portion 41 of the positioning member 32 is pulled out from the insertion hole 22 a of the back mechanism plate 22, the liquid crystal unit 23 is removed from the back mechanism plate 22.

  As shown in FIGS. 18 and 19, when the liquid crystal unit 23 is attached to the pachinko machine 10 of a different model, for example, a positioning member 70 different from the positioning member 32 is used and a fitting member corresponding to the positioning member 70 is used. 71 may be attached to the case main body 31 of the substrate case 30.

  The positioning member 70 includes the same base 40 and locking claws 42 as the positioning member 32, and can be detachably attached to the case body 31 in the same manner as the positioning member 32. However, the positioning member 70 is different in the shape of the insertion portion 72 from the insertion portion 41 of the positioning member 32 (the concave portion 41b is the same). The insertion part 72 is formed on a straight line, and the center thereof coincides with the center of the rail groove 40a.

  The fitting member 71 includes the same base 50 and the locking claw 52 as the fitting member 34, and can be detachably attached to the case body 31 in the same manner as the fitting member 34. However, the fitting member 71 is different from the fitting member 34 in the shape of the fitting portion 73. The fitting portion 73 is formed on a straight line, and its center coincides with the center of the rail groove 50a.

  If the positioning member 70 and the fitting member 71 configured as described above are attached to the case body 31 and the liquid crystal unit 23 is attached to the back mechanism plate 22, the position of the opening 11b of the game board 11 exposing the liquid crystal display 12a changes. The liquid crystal unit 23 can also be attached to the pachinko machine 10 that has been used. Note that the shape and length of the positioning portion and the fitting portion may be appropriately set according to the position of the opening of the game board 11.

  In the above embodiment, the liquid crystal display 12a and the display control board 12b are housed in the case body 31, but the case body has, for example, a main control board for performing lottery for determining hit or miss and a voice control board for controlling sound output. An appropriate control board for performing game execution processing, such as a launch control board for controlling the launch of a pachinko ball in response to a handle operation, may be stored.

  In the embodiment described above, the substrate case 30 is attached to the back mechanism plate 22 by temporary fixing by the positioning member 32 and fixing by the fitting member 34 after positioning, but the substrate case may be attached by any appropriate method.

  In the above embodiment, the rail grooves 40a and 50a are formed in the positioning member 32 and the fitting member 34, and the rails 33c and 35c are formed in the case main body 31, but the rail is formed in the positioning member and the fitting member, for example. A rail groove may be formed in the main body. Also in this case, it is preferable that the rails have different dimensions.

  In the above embodiment, a pachinko machine has been described as an example of a gaming machine to which a board case is attached. However, the present invention can also be applied to gaming machines other than pachinko machines, such as slot machines.
