Medium conveying apparatus

Abstract

A medium conveying apparatus includes a driving source to generate a driving force, a separation roller to separate a medium with the driving force, a mechanical clutch, and an applying part. The mechanical clutch includes a driving wheel rotated by the driving force from the driving source, and a driven wheel coupled to and uncoupled from the driving wheel by rotation of the driving wheel. The driven wheel coupled to the driving wheel transmits the driving force from the driving wheel to the separation roller. The applying part applies, to the driven wheel, a frictional force for restricting rotation of the driven wheel rotated by the driving wheel, and the frictional force applied by the applying part is greater than a frictional force between the driving wheel and the driven wheel.
