There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

A sheet cassette includes a housing, multiple cassettes stacked and provided in the housing, and a rotary cam. The cassettes store a recording sheet. The rotary cam includes multiple pins provided at opposite positions across the axis of rotation of the rotary cam. Adjacent cassettes are offset relative to each other in an offset direction. First receiving parts for receiving the pins are provided one in each of the adjacent cassettes at a first end thereof in the offset direction. The rotary cam rotates with at least one of the pins being in at least one of the first receiving parts of the adjacent cassettes to move the cassettes as connected.

A sheet transport apparatus includes a first casing in which a transport path is formed; a transport unit which transports a sheet along the transport path; a second casing which is provided to be movable with respect to the first casing; a sheet support unit which is rotatably provided in the first casing at a position on a side to which the second casing is moved, the sheet support unit being changeable between a first state, a second state, and a third state and supporting the sheet at least in the third state; and an urging unit which urges the sheet support unit toward the first state within a range from the first state to the second state and which urges the sheet support unit toward the third state within a range from the second state to the third state.

There is provided a recording apparatus with which it is possible to reduce an occupied space to a small size in a configuration of including a mounting unit and a receiving unit.

A sheet supporting apparatus includes first and second units. The first unit includes a first housing, first and second lock portions, a first shaft configured to be supported rotatably with respect to the first housing and to turnably support the first lock portion, and a second shaft configured to be supported rotatably with respect to the first housing and to turnably support the second lock portion. The second unit includes a second housing and first and second engagement portions provided in the second housing and configured to engage respectively with the first and second lock portions. The first and second shafts are disposed such that extension lines of rotational axes of the first and second shafts cross with each other in a plan view.

Tray selection in printing may involve checking for the availability of paper trays which may provide increased paper throughput, and by postponing a switch to use such trays to help avoid excessive tray switching that could adversely affect paper throughput. When a higher ranked tray is unavailable, tray selection may involve checking the availability of lower ranked trays before the present tray is empty, and by postponing a switch to such trays to help avoid excessive tray switching. A change in printing condition may provide a convenient and opportune time to switch between trays without adversely affecting paper throughput.
