Claim:
1. A feed apparatus configured to feed a sheet, comprising: a support unit including a support surface configured to support the sheet; a feed roller configured to feed the sheet supported by the support surface in a feed direction; a first arm configured to rotatably support the feed roller at one end of the first arm, the first arm being swingable by using the other end of the first arm as a swing shaft; a second arm including one end positioned on an upstream side of the other end of the second arm in the feed direction, having a distance between the one end of the second arm and the support surface which is greater than a distance between the other end of the second arm and the support surface, and configured to be swingable with a side of the one end of the second arm as a swing shaft, between a contacting position at which the other end of the second arm makes a contact with the sheet supported by the sheet surface and a separating position at which the other end of the second arm is separated from the sheet supported by the sheet surface; a biasing member configured to bias the second arm toward the contacting position; and an engagement portion provided in the first arm and configured to abut against the second arm from a side of the support surface so as to be engaged therewith, wherein the engagement portion is configured to be separated from the second arm at the contacting position in a case that the feed roller abuts against the sheet supported by the support surface; the engagement portion is configured to be engaged with the second arm in a case that the first arm swings in a direction in which the feed roller is separated from the sheet supported by the support surface; and the second arm is configured to swing from the contacting position to the separating position in conjunction with swing of the first arm in a direction in which the feed roller is further away from the sheet supported by the support surface.
