Abstract: A recording apparatus is provided with a transport roller pair which transports a medium toward a recorder, a feed roller which transports the medium toward the transport roller pair, and a controller which controls the transport roller pair and the feed roller. The controller is capable of executing a combined skew rectification mode which executes one of a first skew rectification operation in which a leading end of the medium abuts the transport roller pair using backward rotation of the transport roller pair and forward rotation of the feed roller and a second skew rectification operation in which the transport roller pair to rotate backward without driving the feed roller and discharges the leading end of the medium to the upstream side of the transport roller pair, and subsequently executes the other of the skew rectification operations.

Abstract: A recording device includes: a liquid discharging head; an opposing section including an opening portion formed at a position that is opposed to the liquid discharging head; a cap section disposed at an inside of the opening portion; and a shutter configured to open and close the opening portion. The opening portion is formed so as to be opened alternately at an upstream position and a downstream position along a medium width direction so as to correspond to the arrangement of a plurality of head chips. The opposing section includes a support portion disposed between two head chips adjacent in the medium width direction and configured to be able to support the shutter disposed at the shielding position.

Abstract: A cap portion includes a first edge portion that is a portion configured to come into contact with the head surface and that extends in the medium width direction and a second edge portion that is a portion configured to come into contact with the head surface, that is located downstream of the first edge portion in the medium conveying direction, and that extends in the medium width direction. One of the first edge portion and the second edge portion is provided with a wiper. The cap portion is movable moving along the medium conveying direction, to a first position at which the cap portion faces the head surface and a second position to which the cap portion retreats from the first position. The wiper wipes the head surface when the cap portion moves from the first position to the second position.

Abstract: A recording device includes a facing portion disposed facing a liquid discharge head and a wiper configured to wipe the head surface of the liquid discharge head by moving in the medium conveying direction with respect to the liquid discharge head. The facing portion is movable, to a recording position at which the facing portion faces the liquid discharge head and a retreat position to which the facing portion retreats from the recording position. The wiper is provided at the facing portion switchably between a first posture in which the wiper is configured to wipe the head surface and a second posture in which the wiper is farther from the head surface than in the first posture. The wiper wipes the head surface when the facing portion moves along the medium conveying direction with the wiper being in the first posture.

Abstract: A recording apparatus includes a recording unit and a document reading unit. The recording unit includes a shaft, and the document reading unit includes a groove forming member. In the groove, an elastically deformable portion configured to make the width of the groove narrower than a maximum diameter of the shaft The shaft has a shape in which a radial dimension changes along a circumferential direction and is provided so as to rotate, and when the elastically deformable portion passes through the shaft in the process of opening the document reading unit from the closed state, the rotation of the shaft is regulated such that the radial dimension of the shaft with respect to the width of the groove is equal to or less than a first dimension smaller than the maximum dimension.
