Sheet transfer apparatus and image reading apparatus

摘要

A sheet transfer apparatus for an image reading apparatus includes a sheet supply tray for storing a sheet; a sheet supply device for drawing out the sheet on the sheet supply tray; a transfer device for receiving the sheet from the sheet supply means and placing the sheet at a predetermined position on a platen of an image reading apparatus for reading the image thereon; a discharge device for discharging the sheet on the platen after reading the image thereon; and a discharge tray for receiving the sheet discharged by the discharge device. A switchback device is disposed above the platen for reversing the sheet when necessary, and includes a switchback path for receiving the sheet to reverse the same. The switchback path includes a first opening portion for opening a first area near an inlet side, and a second opening portion for opening a second area away from the inlet side of the switchback path. The switchback path is easily accessible when the sheet is jammed.
