Abstract

See full text

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 upper tray is disposed to be slidable. A sliding operation of the upper tray enables modes to be switched over between a mode where the optical sensor opposes the upper tray and a mode where the optical sensor opposes the lower tray. One sensor can detect the presence or absence of the sheet in multiple trays.
