Abstract:
1. A recording apparatus comprising: a printing unit that contacts or separates a thermal head with or from a platen using the driving force of an Up/Down (UD) motor; one or more sheet feed units that include sheet feed rollers which are rotated forward or backward by the driving force of an Line Feed (LF) motor transmitted through a transport gear group and pressure rollers which are supported between a pair of roller supporting members and are urged by elastic members to come into pressure contact with the sheet feed rollers, and are provided on an upstream side and a downstream side of the printing unit in a transport path of a recording sheet; a pressure release mechanism including a cam shaft that is rotatably provided so as to tilt the pair of roller supporting members of the one or more sheet feed units against the urging force of the elastic members and separates the pressure rollers from the sheet feed rollers; a pressure release gear group that transmits the driving force of the Line Feed (LF) motor to the cam shaft of the pressure release mechanism, the driving force of the Line Feed (LF) motor being transmitted through the pressure release gear group and the transport gear group, the pressure release gear group including: a tilt adjusting mechanism including: wherein, when the recording sheet is transported, the cam shaft of the pressure release mechanism is rotated, and at least one of the one or more sheet feed units that separate the pressure rollers from the sheet feed roller is selected, and the pair of roller supporting members of any one of the one or more sheet feed units are tilted against the urging force of the elastic members to separate the pressure rollers from the one or more sheet feed rollers, and the cam follower is moved along the tilting groove to adjust the tilting of the tilting plate.
