PROBLEM TO BE SOLVED: To provide a door opening/closing mechanism capable of improving usability.SOLUTION: A door opening/closing mechanism 10 comprises: a first door 11 and a second door 12 covering two sides, respectively with a generally intermediate portion of an opening 2a of a device main body 5 set as a boundary and pivotally supported by both end portions of the opening 2a, respectively; a rotation partition body 20 rotatably provided on an open end of the first door 11; and a guide mechanism rotatably guiding the rotation partition body 20, arranging the rotation partition body 20 at a closed position protruding from a side end surface 11c of the first door 11 when the first door 11 is closed, and arranging the rotation partition body 20 generally at the same surface as the side end surface 11c of the first door 11 when the first door 11 is opened. The guide mechanism includes a protrusion 22 provided on one of the device main body 5 and the rotation partition member 20; and a guide portion 30 provided on the other and guiding the protrusion 22. The guide mechanism retreats in an axial direction when one of the protrusion 22 and the guide portion 30 is urged in the axial direction to open the first door 11 in a state in which the rotation partition body 20 is arranged at the closed position and collides against the other with a stronger force than a predetermined value. |
