A printer wherein a drive roller of a pair of sheet discharge rollers is made of rubber and a driven roller of the pair of sheet discharge rollers is made of synthetic resin; the leading end of a sheet is guided so as to be abutted against the drive roller earlier than the driven roller; the sheet that is in the course of being discharged is guided by a sheet discharge tray so as to come in slidable contact with an edge portion that is on a print head side of a sheet discharge opening. As a result, the printer can provide satisfactory printing conditions quickly with a simple structure and reduce noise leaking from the sheet discharge opening.

Printer having noise noise reduction structure

A printer which is compact, can accurately supply paper and has reduced noise characteristics. Additionally, the printer enables easy correction of paper jams and can be selectively operated in various modes according to the user's preference. The printer includes a paper feed roller which is pivotable between a paper feed position and a non-feeding position, a drive force transmitting mechanism for transmitting a drive force to the paper feed roller, a carriage reciprocatively movable along the width of the paper fed by the paper feed roller, and an intermediate transmission mechanism attached to the side of the carriage. Only when the carriage is in a stand-by position, the intermediate transmission mechanism couples with the drive force transmitting mechanism to transmit to the paper feed roller a paper-feed directional rotating force so as to rotate the paper feed roller to the paper feed position. The intermediate transmission mechanism is preferably an idler rotatably mounted on the side of the carriage. The paper feed roller is preferably driven through a planetary gear mechanism including a sun gear provided on a drive shaft, a paper-feed roller holder rotatably mounted on the drive shaft, and a planetary gear coaxially provided with the paper feed roller supported with the paper-feed roller holder.

Printer having discharge rollers

A printer main body is provided having a print section therein for printing and a sheet feed inlet through which paper is supplied to the print section. An automatic sheet feeder is releasably mountable substantially at position for releasably mounting a manual sheet insertion guide so that each can feed paper through the sheet feed inlet. The manual sheet insertion guide is also releasably mountable on the automatic sheet feeder, preferable at an angle at which sheets can be fed through said sheet feed inlet.
