Abstract:
1. A door opening/closing mechanism fitted on a door that closes and opens an opening formed in a body of an apparatus by being brought into and out of contact with a rim of the opening, comprising: a lever mechanism that brings the door a predetermined distance away from the rim of the opening by pressing the rim of the opening by exploiting action of a lever; and cam mechanisms that permit the door to engage with and disengage from the body at either of right and left sides of the door, the cam mechanisms being able to be brought into a first lock position in which they lie symmetrically at both sides of the door and into a second lock position in which they lie symmetrically at both sides of the door, wherein, when the door is closed, the cam mechanism at both sides are kept in the first lock position and, when the door is opened at one side, the door slides in a direction perpendicular to a rotation axis thereof and thereby causes the cam mechanism at the other side to be brought into the second lock position so that the door rotates with the rotation axis held in the second lock position, and wherein the lever mechanism, by pressing the rim of the opening, permits the door to slide in the direction perpendicular to the rotation axis thereof.
