摘要： In a sheet conveyance apparatus a control unit controls lifting and lowering of a sheet supporting portion by a lifting unit and executes a mixed feeding in one of a plurality of modes including a first mode and a second mode. The mixed feeding is an operation in which a plurality of sheets having different lengths in a width direction orthogonal to a feed direction of a sheet feeding unit are fed by the feeding unit, wherein in the first mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on an instruction to start sheet feeding, and in the second mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on a detection of a sheet by the detection unit.

摘要： A control unit is capable of selectively executing a first mode and a second mode, the first mode being a mode in which a plurality of sheets having different sizes including a non-standard size are fed by the feeding unit, and the second mode being a mode in which a plurality of sheets having different sizes including only standard sizes are fed by the feeding unit. If the detection unit detects a sheet in a state where the supporting portion is located at the second position and the first mode is selected, the control unit waits for an instruction to start sheet feeding without causing the lifting unit to lift the supporting portion to the first position, and causes the lifting unit to lift the supporting portion to the first position in response to the instruction to start sheet feeding.
