ABSTRACT:
In an opening-closing mechanism of a door member for shifting the door member from a closed position for closing an opening portion of a base member to an open position and vice versa, the door member includes a pair of arm portions. Each arm portion includes a circular arc shape gear and a rotary gear disposed in a center of the circular arc of the gear. The base member includes a first fixed gear portion with internal teeth engaging the circular arc shape gear portion, and a second fixed gear portion disposed inside the first fixed gear engaging the rotary gear. The arm portion is held to move vertically through engagements between the first fixed gear portion and the circular arc shape gear portion and between the rotary gear and the second fixed gear portion, so that the door member is shifted along a path corresponding to the first fixed gear portion.
