Abstract
An opening and closing mechanism includes an opening and closing door that is rotatably supported to be movable between a closed position where an opening of an apparatus body is covered and an opened position where the opening is opened, a link member provided in the apparatus body and rotatably supported by a rotary shaft, a guide member having a first guide surface that moves while being in contact with the link member in a case where the opening and closing door moves to the closed position and a second guide surface that moves while being in contact with the link member in a case where the opening and closing door moves to the opened position, and a switching member that guides the link member from the first guide surface to the second guide surface, in which the switching member includes a root portion and an arm extending from the root portion to an opposite side to the apparatus body, and a first rotational moment toward the first guide surface using the root portion as an axis is applied to the arm.
