ABSTRACT:
A keyboard device, in which the rotation of a cover to a closed position is transferred to racks via pawls attached to the shaft of the cover. The force applied by the pawls forces the racks to slide in the direction E and causes cam gears to rotate in the counterclockwise direction. Cam grooves in the cam gears also move in the rotated direction of the cam gears, forcing operating pins engaged in the cam grooves to slide from a first engaging position to a second engaging position. While the operating pins slide relative to the cam grooves, sliding of a circuit board orthogonal to the direction C is corrected by the engaged condition of guide slots and guide pins. Therefore, the operating pins are pressed against the supporting shaft sides of the cam grooves and slid in the C direction, relative to the cam grooves, to the second engaging position. Accordingly, a reinforcer on which the operating pin is fixed and the circuit board are slid in the direction C.
