/Medium Feed Apparatus To Advance Succeeding Sheet Of Medium When Preceding Sheet Of Medium Passes Pick Roller
Abstract

A medium feed apparatus includes a stacking tray, a pick roller located at an upstream side from a feed roller and separation roller in the medium conveyance direction, a first sensor located at an upstream side from the pick roller in the medium conveyance direction, a second sensor located at a downstream side from the feed roller and the separation roller in the medium conveyance direction, and a processor to rotate the pick roller and the feed roller in a medium feed direction to feed a plurality of sheets of the medium stacked on the stacking. The processor stops the pick roller when the second sensor detects a front end of a preceding sheet of the medium and rotates the pick roller again to advance a succeeding sheet of the medium when the first sensor detects a back end of the preceding sheet of the medium.
