Abstract
A recorder comprises, a conveying roller for sending off sheets one by one from stacked sheets of paper; a sheet support biased toward the conveying roller; an feed roller positioned upstream a recording head and downstream the conveying roller; and a spring for biasing the feed roller downstream. The rotation shaft of the feed roller is supported with a bearing. The conveying roller has a semi-cylindrical shape, and the rotation shaft of the conveying roller is provided with a collar. The movement of the rotation shaft of the feed roller within a bearing is restricted, when a trailing edge of the sheet exits from the collar.
