Abstract
A printer includes a lower tray and an upper tray disposed above the lower tray. An optical sensor which detects the presence or absence of a sheet is disposed above the upper tray. The optical sensor is disposed in a roller support member which supports a feeding roller and serves as a swingable swing member. A distance between the optical sensor and the sheet is adjusted by swing of the roller support member according to the number of sheets.
