Abstract

A technology that enables downsizing of an apparatus is to be provided. The technology includes: a stacking unit configured to expand or contract in a conveyance direction of a print medium to be conveyed and discharged, and configured to be movable in a width direction of the print medium, which intersects with the conveyance direction, and to be capable of stacking the print medium to be discharged; and a transmission unit configured to transmit a driving force from a drive source to the stacking unit, wherein the transmission unit transmits the driving force such that a timing at which the stacking unit expands or contracts in the conveyance direction differs from a timing at which the stacking unit moves in the width direction.
