Abstract
A sheet-shaped medium feeding device is provided. A power transmission mechanism includes a retardation mechanism configured to retard rotation start timing of a pick-up roller than movement start timing of a pressing member when the pressing member starts to move from a stand-by position toward the pick-up roller. The retardation mechanism includes a driving side rotational member and a driven side rotational member which are configured to rotate around a common center axis. When the driving side rotational member rotates around the center axis in a predetermined rotation direction by a predetermined play angle, the driving side rotational member is engaged with the driven side rotational member to integrally rotate the driven side rotational member in the rotation direction.
