摘要： 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.

摘要： 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.

摘要： An auxiliary roller is disposed in the proximity of sides of feed rollers and in the proximity upward from a separation pad. At the print time, the auxiliary roller is slightly projected toward the side of print sheet from roller faces of the feed rollers. The auxiliary roller is displaced as paper is displaced in a stack direction of the paper, and can be freely rotated. A hopper is moved up, paper is pressed against the feed rollers, and the separation pad abuts the feed rollers. Then, the feed rollers and a transport roller are rotated forward for feeding the paper to the transport roller. Further, the paper is sent from the transport roller at a distance equal to or greater than the length along the feeding path between the position of the front end of paper placed in a paper feed tray and the abutment center point of the separation pad and the feed rollers. Subsequently, the feed rollers and the transport roller stop, the hopper is moved down, and the separation pad is brought away from the feed rollers. Then, the transport roller is rotated reversely the rotation amount corresponding to the length or more for returning the paper.

摘要： Springs 34 and 35 are located on the back face of a paper cassette, between a movable plate 32 and a bar 31, coupled with a side edge aligner 27. A slot extending in the direction in which a spring load is generated is formed in the movable plate, and a hook portion is formed at the end of the spring in the direction in which the spring is extended or contracted. The length of the slot and the length of the spring end in the direction in which the spring load is generated differ for the individual springs, and correspond to the distance the movable plate is displaced. That is, a size difference is defined for each spring until the spring load is applied. During the insertion of the paper cassette, the movable plate is displaced by the mechanism constituted by the groove cam 41 and the boss 36a, and in accordance with the displacement, different spring loads are multiply applied the paper side edge aligning member via the bar.
