Abstract
A sheet stacking device includes a tray having a sheet loading surface on which a sheet fed in a predetermined feeding direction is loaded. The tray includes a main tray, an extension tray and a first detection part. The first detection part includes a first sensor, a first detected piece and a first contact piece. The first detected piece is turnably supported by the extension tray and switches the first sensor between an ON state and an OFF state. The first contact piece is turnably supported by the first detected piece, and protrudes above and retracts below the sheet loading surface.
Claims9
A sheet loading device comprising a tray having a sheet loading surface on which a sheet fed in a predetermined feeding direction is loaded, wherein
- the tray includes:
- a main tray having a storage part on an upstream side in the feeding direction;
- an extension tray displaceable between a storage position where the extension tray is stored in the storage part and an extension position where the extension tray extends from the storage part to the upstream side in the feeding direction;
- and
- a first detection part provided in the extension tray and detecting a first size sheet,
- the first detection part includes;
- a first sensor;
- a first detected piece turnably supported by the extension tray to switch the first sensor between an ON state and an OFF state, and
- a first contact piece turnably supported by the first detected piece, and protruding above and retracting below the sheet loading surface, wherein
- in a state where the extension tray is arranged in the extension position,
- when the first size sheet is not loaded on the extension tray, the first contact piece is turned so as to protrude above the sheet loading surface and the first detected piece is turned so as to switch the first sensor from the ON state into the OFF state, and
- when the first size sheet is loaded on the extension tray, the first contact piece is turned so as to be retracted below the sheet loading surface by coming into contact with the first size sheet, and the first detected piece is turned so as to switch the first sensor from the OFF state into the ON state, and
- in a state where the extension tray is arranged in the storage position, the first contact piece comes into contact with an upper wall of the storage part and is turned so as to retract below the sheet loading surface, and the first detected piece interferes with a restriction part provided in the storage part and is inhibited from being turned so as to switch the first sensor from the OFF state into the ON state.
