Abstract
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 …
