Abstract
A medium feeder includes a first rotation body; a second rotation body which engages with the first rotation body while overlapping with the first rotation body, and disengages from the first rotation body in response to the presence of the feed target medium nipped between the first and second rotation bodies; a rotation body support member which supports the second rotation body, and is configured to be movable between an advancing position where the second rotation body engages with the first rotation body and a retreating position where the second rotation body disengages from the first rotation body; and a detection unit which detects migration of the rotation body support member to the retreating position.
