Feed apparatus and image recording apparatus

摘要

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.

主权项

1. A feed apparatus comprising:
a support section configured to support a sheet; a feed roller configured to feed the sheet supported by the support section; an arm configured to rotatably support the feed roller at one end, the arm being swingable by using the other end as a shaft of swing movement; a driving source configured to perform forward rotation and reverse rotation; a driving transmission unit configured to transmit a rotary driving force from the driving source to the feed roller; a swingable member coupled to the feed roller or the arm, the swingable member being configured to swing by the rotary driving force applied from the driving transmission unit; a first regulating section configured to abut against the swingable member to regulate the swing movement of the swingable member at a first position protruding toward a side of the support section as compared with the feed roller; and a second regulating section configured to abut against the swingable member to regulate the swing movement of the swingable member at a second position retracted with respect to the support section as compared with the feed roller, wherein the feed roller is rotated in a rotational direction so that the sheet is fed in a case that the rotary driving force of the forward rotation is applied from the driving source, wherein the feed roller is rotated in an opposite rotational direction in a case that the rotary driving force of the reverse rotation is applied from the driving source, wherein the swingable member is swingably moved from the first position to the second position in a case that the rotary driving force of the forward rotation is applied from the driving source, wherein the swingable member is swingably moved from the second position to the first position in a case that the rotary driving force of the reverse rotation is applied from the driving source, and wherein the swingable member is configured to make a contact with a top surface of the sheet supported by the support section.
