In addition, a connector insertion / extraction opening 194 for exposing a connection connector (board-to-board connector) 93 of the effect control board 90 to the right outward is formed on the right side wall of the top case main body wall 191, and the left side wall is formed. A connector insertion / extraction opening 195 for exposing the connection connector 103 of the image control board 100 to the left outward is formed.

  Further, the top case 190 is formed with six bottomed cylindrical hollow bosses 196 protruding forward from the back surface of the top case main body wall 191. The top case 190 is fixed to the bottom case 160 with screws. The screw (not shown) is received in the hollow portion of the hollow boss 196, and a screw portion of the screw is inserted through a through hole formed in the center of the bottom portion. The hollow bosses 196 are formed in the same number (eight places) as the board mounting holes 97, 104, 105, 142 of the respective boards 90, 100, 140 and the screw bosses 167 of the first housing part 170, and the arrangement interval is also set. It corresponds. Further, the top case 190 is formed with four substrate holders 197 projecting forward from the back surface of the top case body wall 191. When the top case 190 is attached to the bottom case 160, the two upper substrate substrates 197 are formed. The presser 197 is close to or abuts on the surface of the effect ROM board 110 (non-mounting position of the electronic component), and the two lower board pressers 197 are close to or touching the surface of the sound ROM board 130 (non-mounted position of the electronic component). It comes to touch. Thus, even when the effect ROM substrate 110 and the sound ROM substrate 130 are warped in the thickness direction, the effect ROM substrate 110 and the sound ROM substrate 130 are located between the substrate holders 120 and 132 and the substrate holder 197. Therefore, the ROM substrates 110 and 130 can be stably held. Note that a number of elongated slit-shaped long holes 198 are formed in the upper and lower side walls of the top case 190, and these long holes 198 serve as intake ports for taking cooling air into the case.

  In order to assemble the liquid crystal unit 40 configured as described above, the effect control board 90, the image control board 100, the effect interface board 140, the bottom case 160, and the top case 190 are integrally assembled as a subassembly, and then the subassembly. This is performed by the procedure of assembling the (control board assembly 80) to the liquid crystal display device 50. Then, although this assembly order is demonstrated in detail below, the description about the insertion / extraction of the harness which connects between each board | substrate is abbreviate | omitted.

  In order to assemble the control board assembly 80, first, the effect control board 90 and the image control board 100 are inserted into the first housing part 170 of the bottom case 160 in a board-to-board connection state, and six screw bosses are inserted. 167. When the effect control board 90 and the image control board 100 are housed in the first housing 170, the board holder 120 is brought close to the surface side of the image control board 100, and the front pin 122 of the board holder 120 is moved to the image control board 100. The board holder 120 is inserted into a front pin hole (not shown) and attached to a predetermined position on the image control board 100. At this time, the screw boss 168 of the bottom case 160 is inserted into the boss portion 124 (stepped hole 125) of the substrate holder 120 through a passage hole (not shown) of the image control substrate 100.

  Then, the effect ROM substrate 110 is approached from the front side of the substrate holder 120, and the rear pin insertion hole 113 of the effect ROM substrate 110 is pressed forward and applied to the rear pin 123 of the substrate holder 120, and the effect ROM substrate 110 is inserted into the substrate holder. Mount on 120. At the same time, the connection connector 112 of the effect ROM board 110 is fitted with the connection connector 106 of the image control board 100, and the effect ROM board 110 and the image control board 100 are connected by a board-to-board. When the effect ROM board 110 and the image control board 100 are fitted and connected in this manner, screws (not shown) are screwed into the screw bosses 168 from the surface side of the effect ROM board 110 through the screw insertion holes 114, and the effect ROM board 110. Secure with screws. In the same manner as the effect ROM board 110, the sound ROM board 130 is also mounted on the image control board 100 via the board holder 132. A connector (not shown) of the sound ROM board 130 and the image control board 100 are connected. The connector 107 is board-to-board connected.

  As a result, the effect control board 90 and the image control board 100 on which the effect ROM board 110 and the sound ROM board 130 are mounted are attached to the first housing portion 170 of the bottom case 160 so as to cover these boards. Then, the first case 170 of the bottom case 160 is closed by the top case 190 by overlapping the top case 190 from behind the bottom case 160. When the first housing part 170 is closed, a screw (not shown) is inserted into the hollow boss 196 from the rear (front side) of the top case 190, and the effect control board 90 and the image control board housed in the first housing part 170. The effect control board 90 and the image control board 100 on which the two ROM boards 110 and 130 are mounted are screwed and fastened to the screw boss 167 of the bottom case 190 through the board mounting holes 97, 104, and 105. The screw is fixed to the board case 150 in a state of being in contact with the screw. In the closed state of the board case 150, the connection connectors 93, 94, 95 of the effect control board 90, the sound volume 96, and the connection connector 103 of the image control board 100 are the top case opening 193 opened in the top case 190 and It is exposed to the outside of the case through the connector insertion / extraction openings 194, 195, and the connector can be connected and the volume can be operated even in the closed state where the top case 190 is attached to the bottom case 160. As described above, the top case 190 closes only the first housing part 170, and the second housing part 180 is always open.

  Subsequently, in order to attach the effect interface board 140 to the second housing portion 180 of the bottom case 160, the detachable hook 182 is displaced in advance to the right standby position. Then, the effect interface board 140 is inserted into the second housing part 180, and the pin fitting insertion hole 144 of the effect interface board 140 is inserted in alignment with the positioning pin 182c of the detachable hook 182. As a result, the rendering interface board 140 is placed on the base 183 and the support rib 184 of the bottom case 160 in the second housing portion 180, and when the detachable hook 182 is slid to the left from this state, it is connected to the detachable hook 182. The produced effect interface board 140 also slides to the left while being guided by the taper surface 185 c of the holding rib 185 together with the attaching / detaching hook 182.

  Here, the connection connector 145 of the effect interface board 140 and the connection connector 93 of the effect control board 90 are opposed to each other in the left-right direction (sliding direction). When the claw is engaged with the left protrusion claw locking groove 181L (that is, when the detachable hook 182 reaches the connection position), the connection connector 145 of the effect interface board 140 is fitted into the connection connector 93 of the effect control board 90. Connected together. In other words, since the slide direction of the effect interface board 140 and the fitting direction of both the connecting connectors (board-to-board connectors) 93 and 145 coincide, the slide operation of the effect interface board 140 by the detachable hook 182 is accompanied. Thus, the connection connector 145 of the effect interface board 140 and the connection connector 93 of the effect control board 90 are fitted and connected.

  When the connection connector 145 of the effect interface board 140 is fitted and connected to the connection connector 93 of the effect control board 90 as described above, the effect interface board 140 is connected to the detachable hook 182 and the detachable hook 182 is picked. Since it is only necessary to grab the part 182d and slide it to the left, it is avoided that the operator's fingers touch the effect interface board 140 and the effect control board 90, and these are caused by static electricity charged on the human body of the operator. It is possible to prevent the substrate from electrostatic breakdown. In addition, when the attachment / detachment hook 182 is slid, the engaging arm portion 182b of the attachment / detachment hook 182 is almost simultaneously connected with the connection connector 145 of the effect interface board 140 and the connection connector 93 of the effect control board 90. A click feeling is obtained when the is engaged with the protrusion claw locking groove 181L at the connection position, so that the operation feeling at the time of connection between the substrates can be improved.

  In addition, before the detachable hook 182 reaches the connection position (before the connection connector is fitted), the stopper 186 of the bottom case 160 is fitted into the U-shaped groove 143 of the effect interface board 140 and the effect interface board 140 is moved up and down. Since the edge portion is pressed by the holding rib 185 and the slide position of the effect interface board 140 is corrected, it is possible to suppress poor connection between the connection connectors 93 and 145.

  Thus, in the state where the effect interface board 140 and the effect control board 90 are connected, the pair of board mounting holes 142 of the effect interface board 140 and the two screw bosses 167 of the second housing portion 180 are aligned, and this effect interface. By screwing and fastening a screw (not shown) to the screw boss 167 from the front surface side of the substrate 140 through the substrate attachment hole 142, the effect interface substrate 140 is fixed to the second housing portion 180 of the bottom case 160 with screws.

  In this way, the control board assembly 80 in which the effect control board 90, the image control board (including the ROM boards 110 and 130) 100, and the effect interface board 140 are integrally assembled to the board case 150 and sub-assembled is obtained. The control board assembly 80 can be assembled to the liquid crystal display device 50 as a single unit.

  In the above description, after the top case 190 is attached to the bottom case 160 and the first housing part 170 is closed, the effect interface board 140 is attached to the second housing part 180 of the bottom case 160. On the contrary, the order of attaching the top case 190 to the bottom case 160 after the production interface board 140 is attached to the second housing part 180 of the bottom case 160 may be used.

  Next, in order to assemble the control board assembly 80 to the liquid crystal display device 50, first, the guide ribs 164 of the bottom case 160 of the control board assembly 80 are inserted into the guide holes 74 of the rear case 70 of the liquid crystal display device 50 from the rear, From this state, the guide rib 164 is moved rightward along the guide hole 74 and engaged with the locking piece 74 a of the guide hole 74. When the guide rib 164 is engaged with the locking piece 74a, the front / rear and vertical movement of the control board assembly 80 with respect to the liquid crystal display device 50 is restricted. At the same time, when the board-side latching claw 165 of the control board assembly 80 moves to the right, the inclined surface 165a of the board-side latching claw 165 becomes the inclined surface of the panel-side latching claw 76 of the liquid crystal display device 50. When the board-side latching claw 165 exceeds the panel-side latching claw 76, the entire lock piece 75 is elastically returned rearward when the board-side latching claw 165 exceeds the panel-side latching claw 76. Thus, the board-side locking claw 165 and the panel-side locking claw 76 are engaged with each other by bringing the locking surfaces 76b and 165b into contact with each other. When the board side latching claw 165 and the panel side latching part 76 are engaged, the lateral movement of the control board assembly 80 with respect to the liquid crystal display device 50 is also restricted, and the control board assembly 80 is assembled to the liquid crystal display device 50 in a locked state. . In this way, the liquid crystal display device 50 and the control board assembly 80 are integrally assembled to obtain the liquid crystal unit 40 as a final assembly.

  In the state in which the liquid crystal unit 40 is assembled in this way, the locking claws 76 and 165 that connect the liquid crystal display device 50 and the control board assembly 80 are concealed on the back side of the effect interface board 140 and are externally provided. Since the operation unit 77 of the lock piece 75 cannot be accessed, the image control board assembly 80 can be prevented from being carelessly detached from the liquid crystal display device 50.

  Next, a procedure for removing the control board assembly 80 from the liquid crystal display device 50 in the liquid crystal unit 40 assembled in this way will be described below.

  First, two screws (not shown) of the effect interface board 140 are loosened and removed from the rear surface side of the liquid crystal unit 40, and the screw fixing of the effect interface board 140 to the bottom case 160 is released. In this state, when the grip portion 182d is grasped and the entire attachment / detachment hook 182 is slid to the right, the effect interface board 140 connected thereto is also slid to the right together. Then, with this operation, the connection connector 145 of the effect interface board 140 is removed from the connection connector 93 of the effect control board 90, and the board-to-board connection between the effect control board 90 and the effect interface board 140 is released. The Then, after sliding the attachment / detachment hook 182 to the right standby position, the effect interface board 140 is moved backward, and the pin insertion hole 144 of the effect interface board 140 is removed from the positioning pin 182c of the attachment / detachment hook 182. Thus, the effect interface board 140 can be detached from the second housing part 180 of the bottom case 160.

  When the effect interface board 140 is removed from the second housing portion 180, the lock piece 75 of the liquid crystal display device 50 is exposed rearward, thereby enabling the lock piece 75 to be released. When the operation portion 77 of the lock piece 75 becomes accessible in this way, when the operation portion 77 is pushed forward, the panel side latching claw 76 of the lock piece 75 is separated from the board side latching claw 165. It is elastically deformed (forward), whereby the engagement between the two is released.

  When the control board assembly 80 (excluding the effect interface board 140) is moved to the left in the released state, the guide ribs 164 of the bottom case 160 are moved to the left along the guide holes 74 of the rear case 70. Moving. When the guide rib 164 hits the inner end of the guide hole 74, if the control board assembly 80 is moved backward, the guide rib 164 is pulled out from the guide hole 74 and the control board assembly 80 is removed from the liquid crystal display device 50. Can be removed from.

  In this control board assembly 80, in order to separate the effect control board 90, the image control board 100, and the ROM boards 110, 130 from the board case 150, it is only necessary to perform a procedure reverse to the above-described mounting procedure. Description is omitted.

  As described above, in the pachinko machine PM according to the present embodiment, if the presentation control board 90, the image control board 100, and the presentation interface board 140 are assembled in advance to the board case 150 as the board holding member and prepared as a subassembly, Since the substrate replacement in the liquid crystal unit 40 can be performed only by attaching the subassembly to the liquid crystal display device 50, the work efficiency of the substrate replacement in the liquid crystal unit 40 can be improved. Further, by sharing a mounting structure with the bottom case 160 among the plurality of types of liquid crystal display devices 50, even when the design of the liquid crystal display unit 40 is changed due to the size change of the liquid crystal display panel 51, different liquid crystal displays. Since the control board assembly 80 can be used in common with the apparatus 50, it is possible to reduce the manufacturing cost of the pachinko machine PM (game machine), promote environmental protection by recycling, reduce inventory burden, etc. It is possible to contribute to

  Corresponding to the operation of mounting the effect interface board 140 in the second housing part 180 of the bottom case 160, the connection connector 93 of the effect control board 90 and the connection connector 145 of the effect interface board 140 are fitted and connected (board (To-board connection), the time required for wiring work is shortened by eliminating the trouble of wiring connection between the production control board 90 and the production interface board 140. Efficiency is improved.
