Abstract
A sheet is fed to a printing zone of a printhead by a feed roller and a pressure roller. An elastic sheet guide plate is joined to a lever supporting the pressure roller. The guide plate comes into contact with the feed roller upstream from a nip defined by the feed roller and the pressure roller. A nip between the conveying roller and the guide plate allows to register the sheet. The sheet, after having passed through the nip formed between the conveying roller and the guide plate, is directed to the printing zone of the printhead by the guide plate. As the guide plate extends from the printhead side end portion of the lever to a position just before the printhead, the sheet trailing edge is prevented from interfering with the printhead. Ink will not soil the sheet trailing edge, and, it is possible to achieve a high quality printing to a position extremely nearby the sheet trailing edge by using the guide plate.
