摘要:
A sheet feeding device includes a driven roller that rotates in response to movement of a sheet, and a rotary encoder that detects a moving distance of the sheet based on rotation of the driven roller. The driven roller and the rotary encoder are connected by a gear unit having backlash. When the sheet moves in a reverse direction and thereby the driven roller rotates in reverse, the rotary encoder does not detect the moving distance of the sheet.
