Abstract: An image recording apparatus having a lens unit and a mirror unit. The lens unit and the mirror unit are movably supported by a frame of the apparatus. A cam plate is provided at the lens unit, and a lever is in abutment with the cam plate. When the lens unit is moved in a direction, the cam plate is also moved, so that the lever is pivotally moved. The lever is abutted on the mirror unit. The pivotal motion of the lever, the mirror unit is also moved in another direction. The cam plate has a plurality of cam surfaces each defining respective copying magnifications.

Abstract: An image recording apparatus for recording an image corresponding to an original on a photosensitive recording medium by irradiating light onto the original and converging light from the original onto the photosensitive recording medium. The apparatus includes a lens unit vertically movably supported by the frame, a plurality of position setting holes arrayed in a vertical direction of the frame, position setting means provided on the lens unit and capable of being inserted into one of the position setting holes for fixing the lens unit to the frame, urging means provided on the lens unit for urging the position setting means toward the frame to project the position setting means, actuating means provided on the lens unit for actuating the position setting means so that the position setting means retracts and moves away from the frame against urging force of the urging means when electric current is supplied to the actuating means.
