Claim:
A recording medium output apparatus that outputs a sheet-like recording medium being transported onto a stack tray on which recording media are stacked, comprising: an output unit that is free to move in a recording medium width direction intersecting the transport direction of the recording medium being transported and outputs the recording medium toward the stack tray at a position higher than the stack tray; and a drive unit that moves the output unit in the recording medium width direction before and after a trail edge of the recording medium, which is to be output from the output unit, leaves the output unit, wherein the drive unit drives the output unit as to cause the output unit to change a distance traveled by the recording medium in the recording medium width direction from a time when the trail edge of the recording medium leaves the output section to a time when the trail edge of the recording medium lands on the stack tray according to a size of the recording medium, a type of the recording medium, or a height position of the uppermost recording medium on the stack tray.
