Abstract
Even if a sheet surface detection mechanism outputs a signal indicating that an uppermost sheet among blown-up sheets is within a conveyance range, if a trailing edge sheet surface sensor outputs a signal indicating that the uppermost sheet among the blown-up sheets is lower than the conveyance range when the conveyed uppermost sheet passes by the trailing edge sheet surface sensor, a lifting and lowering portion is controlled to lift the tray so that the uppermost sheet is positioned within the conveyance range.
