Recording medium feed apparatus

A recording medium feed apparatus comprising:

• a manual feed tray provided openably and closably with respect to a housing of an image recording apparatus having a recording portion that records an image on a recording medium;
• a feed roller that feeds the recording portion with a recording medium mounted on the manual feed tray in an opened state;
• an arm body having a first end portion and a second end portion, the first end portion being rotatably attached to the housing;
• a feed roller unit having a front end portion and a base end portion, the front end portion being provided with the feed roller, the base end portion being rotatably attached to the second end portion of the arm body;
• and
• a driving source provided in the housing and that transfers a driving force to the feed roller,
• wherein the arm body and the feed roller unit are housed substantially vertically inside the housing when the manual feed tray is in a closed state with respect to the housing, and
• as the manual feed tray changes from the closed state to the opened state, the arm body in a substantially vertical state is inclined toward an outside of the housing, while a folding angle of the feed roller unit with respect to the arm body increases so that the feed roller abuts against an uppermost surface of a recording medium mounted on a mounting surface of the manual feed tray.
