摘要：
A sheet supply apparatus includes a sheet supply tray for stacking a sheet, and an auxiliary tray movable between a support position where the auxiliary tray supports a portion of the sheet stacked on the sheet supply tray and a storage position where the auxiliary tray overlaps the sheet supply tray. A sheet supply device supplies the sheet stacked on the sheet supply tray. A sheet detection device is mounted on the auxiliary tray for detecting the sheet stacked on the sheet supply tray, and a tray position detection device detects a position of the auxiliary tray between the support position and the storage position. An identifying device identifies a length of the sheet in a sheet supply direction based on detection results of the sheet detection device and the tray detection device.
