A dealing board has a dealing board main body having a box-like structure. The box-like structure includes a top plate, bottom plate, front face plate and rear face plate. The top plate is forwardly slanted relative to the top of a desk on which the main body is mounted and has a number of openings formed therein. The dealing board further has a plurality of panel units arranged in the opening. A receiving device secured to a bent portion of the top end of the front face plate or the rear face plate forms a gap. The dealing board further has a screen plate attached to a top end of the one of the rear face plate or the front face plate which is not bent, and a fixing device is provided on the screen plate so as to be removable by set screws. The dealing board further has a card insertion slot of a reader-writer for reading and writing information on memory cards, a card take-out button placed near the card insertion slot, and a cover covering the card slot and card take-out button. One end side of the cover has an attaching portion for attaching the cover onto the main body, a fulcrum having a hinge portion for opening and closing the cover, and a holding mechanism for holding the cover at its erect position.

Dealing board

A key unit is provided with a first print substrate on which a contact portion and a LED capable to be mounted on flat surface are mounted, a conductive contact rubber, placed on the first print substrate, having a movable contact portion which can contact with the contact portion and an open portion in which the LED is accommodated, a key button placed on the conductive contact rubber, a LED lens, placed on the edge portion of the open portion of the conductive contact rubber, which leads the light beam generated from the LED in the open portion, and a key case having a through hole into which the key button is slidably inserted and a lens insertion hole into which the LED lens is inserted. The key unit may also be provided with a chip resistor to protect the LED, which is mounted on the first print substrate at a position below a lower end face of the key case. Further, a key button may be inserted into the through hole and a position where the LED lens is inserted into the lens insertion hole, the width of the LED lens is made to be shorter than that of the LED.

Key unit

A panel unit for a dealing board has a keyboard unit provided with buttons, the keyboard unit has a printed substrate arranged on a display, fixed contacts which form switches provided for the buttons, and electric conductive contact rubber located on the printed substrate and provided with moving contacts opposing the fixed contacts. A panel is positioned on the electric conductive contact rubber and provided with the buttons. The panel has holes, the buttons are fitted into the holes to be vertically moveable so that the fixed contacts of the printed substrate come into contact with the movable contacts of the electric conductive contact rubber. The buttons are provided with an engagement portion for preventing the buttons from coming off the panel and the electric conductive contact rubber and the printed substrate have relief holes in which the buttons are fitted when the engagement portion holds the buttons.

Panel unit of dealing board

A panel unit for a dealing board has a display and a keyboard unit provided with buttons. The display is divided into individual indications which display function names corresponding to the buttons. The keyboard unit has a printed substrate arranged on the display, fixed contacts which form switches provided for the buttons, and electric conductive contact rubber located on the printed substrate and provided with moving contacts opposing the fixed contacts. A panel is positioned on the electric conductive rubber and provided with the buttons. The panel has holes, the buttons are fitted into the holes to be vertically movable so that the fixed contacts of the printed substrate come into contact with the movable contacts of the electric conductive rubber. The buttons are provided with an engagement portion for preventing the buttons from coming off the panel and the electric conductive contact rubber and the printed contact have relief holes in which the buttons are fitted when the engagement portion holds the buttons, as well as belt-like through holes for making the individual indications corresponding to the buttons visible.
