Abstract
A sheet supporting apparatus includes a sheet supporting portion, a regulation member, a flag portion, a detection portion, and a holding portion con. At the holding position, the holding portion supports the flag portion at the upper position in a case where the sheet supporting portion is positioned at the first position, and, at the allowing position, the holding portion allows movement of the flag portion to the lower position in a case where the sheet supporting portion is positioned at the second position. A lower end of the flag portion is positioned above the regulation surface in a case where the flag portion is positioned at the upper position, and is positioned below the regulation surface in a case where the flag portion is positioned at the lower position.

A sheet supporting apparatus comprising:
- a sheet supporting portion configured to support a sheet and to move between a first position and a second position positioned above the first position;
- a flag portion supported to be movable between an upper position and a lower position and configured to be positioned at the lower position in a case where the sheet is not supported by the sheet supporting portion positioned at the second position;
- a detection portion configured to detect that the flag portion is positioned at the lower position;
- and
- a holding portion configured to move between a holding position and an allowing position,
- wherein, at the holding position, the holding portion supports the flag portion at the upper position in a case where the sheet supporting portion is positioned at the first position, and, at the allowing position, the holding portion allows movement of the flag portion to the lower position in a case where the sheet supporting portion is positioned at the second position,
- wherein the sheet supporting portion comprises a pressing portion configured to press the holding portion, and
- wherein the holding portion is pressed by the pressing portion from the holding position toward the allowing position in a case where the sheet supporting portion moves from the first position to the second position.
