Abstract
An image formation apparatus includes, in an apparatus body, a sensing portion which senses presence or absence of depression by a paper feed unit. The sensing portion includes a slider provided to be slidingly movable along a mounting direction of the paper feed unit, a push switch arranged behind the slider along the mounting direction, and a first elastic body and a second elastic body for elastically biasing the slider toward a direction away from the push switch. The first elastic body is interposed between the slider and a portion which does not relatively move with respect to the apparatus body, and the second elastic body is interposed between the slider and a switch portion of the push switch.
