Abstract
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.

A sheet supporting apparatus configured to support a sheet, the sheet supporting apparatus comprising:
- a first unit including a first housing, a first shaft configured to be supported rotatably with respect to the first housing, a first lock portion provided on a first shaft, a second shaft configured to be supported rotatably with respect to the first housing, and a second lock portion provided on the second shaft;
- a second unit including 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;
- a manipulating portion configured to move between first and second positions by being manipulated;
- and
- an interlock mechanism configured to interlock the first and second lock portions in response to a movement of the manipulating portion,
- wherein 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, and in response to movement of the manipulating portion,
- the second lock portion is configured to rotate, along with rotation of the second shaft, so as to separate from the second engagement portion in a state where the second lock portion is engaged with the second engagement portion, and
- the first lock portion is configured to rotate, along with rotation of the first shaft, so as to separate from the first engagement portion in a state where the first lock portion is engaged with the first engagement portion.
A sheet supporting apparatus configured to support a sheet, the sheet supporting apparatus comprising:
- a first unit including a first housing, a first shaft configured to be supported rotatably with respect to the first housing, a first lock portion provided on a first shaft, a second shaft configured to be supported rotatably with respect to the first housing, and a second lock portion provided on the second shaft;
- a second unit including 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;
- a manipulating portion configured to move between first and second positions by being manipulated;
- and
- an interlock mechanism configured to interlock the first and second lock portions in response to a movement of the manipulating portion, the interlock mechanism comprising:
- a gear portion rotating together with the first lock portion, and
- a move portion including a rack portion engaging with the gear portion and a pressure surface configured to press the second lock portion and configured to move in a move direction in parallel with the second shaft, the pressure surface being configured to press the second lock portion from the move direction by the move portion that moves in the move direction,
- wherein 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.
