Further, a liquid crystal relay substrate 56 is installed at a position above the effect / image control substrate 90 on the rear surface of the case main body 54 and fixed with screws. As described above, in the liquid crystal unit 40, the production / image control board 90 and the liquid crystal relay board 56 are arranged side by side, so that these boards are arranged side by side like the conventional liquid crystal unit. The thickness before and after the liquid crystal unit can be reduced. Thereby, it becomes possible to make a game component such as a central ornament arranged on the board surface of the game board 10 larger and more dynamic.

  Next, the shield cover 155 is attached to the rear surface of the case main body 54 so as to cover the entire rear surface side of the effect / image control board 90, and the first substrate cover 160 is covered so as to cover the shield cover 155 and the rear surface side of the liquid crystal relay substrate 56. Is mounted on the rear surface of the case main body 54 and fixed with screws, and the sealing member 161 is attached to the first substrate cover 160. When the shield cover 155 is attached to the case main body 54, a gasket (a thin metal net-like member rolled into a cylindrical shape at a portion where the shield cover 155 and the case main body 54 abut (front ends of the upper, lower, left and right side walls of the shield cover 155). ). Since the shield cover 155 is pressed against the inner surface of the first substrate cover 160 by this gasket, the shield cover 155 is not displaced in the first substrate cover 160 without fixing the shield cover 155 with screws. . As described above, the effect / image control board 90 is covered with the shield plate 150 and the shield cover 155, so that the electromagnetic wave to the effect / image control board 90 is blocked to suppress the influence of electromagnetic noise. Can be done.

  Next, the interface board 140 is fixed to the front side of the second board cover 165 with screws. Then, the upper and lower mounting pieces 170, 170 of the second substrate cover 165 are inserted into the mounting grooves 175, 175 formed in the case main body 54 from the rear side, and the handle portion 169 is further operated to the case main body 54. The second substrate cover 165 is slid leftward to attach the second substrate cover 165 to the case main body 54. As described above, when the second substrate cover 165 is slid to the left with respect to the case main body 54, the connection connector 145 of the interface substrate 140 attached to the second substrate cover 165 becomes the fourth effect / image control substrate 90. The interface board 140 and the effect / image control board 90 are electrically connected (board-to-board connection) by being fitted and connected to the connection connector 93. Then, the second board cover 165 is fixed to the case body 54 using a plurality of screws (not shown), and the control board assembly 80 is assembled.

As described above, according to the liquid crystal unit 40 according to the present embodiment, the connector 145 of the interface board 140 is moved by sliding the second board cover 165 to which the interface board 140 is attached to the left of the case main body 54. The interface board 140 and the effect / image control board 90 are electrically connected (board-to-board connection) by being fitted and connected to the fourth connection connector 93 of the effect / image control board 90. Therefore, the board-to-board connection work of the effect / image control board 90 and the interface board 140 and the mounting work of the second board cover 165 can be simultaneously performed by one work. Therefore, it is possible to more efficiently perform the attachment / detachment work (exchange work) of the effect / image control board 90 and the interface board 140. In addition, by incorporating a board connection mechanism for connecting the effect / image control board 90 and the interface board 140 into the second board cover 165, the cost of the control board assembly 80 can be reduced compared to providing a board connection mechanism separately. it can.

Plate portion 52b, and frame portion 52a and plate portion 52b are integrally formed using a transparent resin material. Therefore, the cost of the screen protective cover can be reduced as compared with a conventional screen protective cover having a frame portion and a protective sheet provided separately from the frame portion. As the resin material for forming the screen protection cover 52, for example, polycarbonate or the like is used. However, in recent years, these resin molding techniques have been improved to ensure the transparency of the plate portion 52b to such an extent that the liquid crystal screen can be visually recognized. As a result, the frame portion 52a and the plate portion 52b can be integrally formed.

  Further, according to the liquid crystal unit 40, the effect / image control board 90 is disposed in a state where the front and back are covered by the shield plate 150 and the shield cover 155. Therefore, the influence of electromagnetic noise can be suppressed by blocking electromagnetic waves to the production / image control board 90. Further, since the connection connectors for electrical connection with the game component 19 are gathered and arranged on the interface board 140, the number of connection connectors arranged on the effect / image control board 90 can be reduced. Therefore, the number of insertion holes formed in the shield cover 155 for connecting the communication harness and the connection connector to the connection connector of the effect / image control board 90 can be reduced, and thereby the electromagnetic shielding effect by the shield cover 155 can be reduced. Can be further enhanced.
