Abstract
A sheet supply apparatus can be releasably attached to a printer. The sheet supply apparatus includes a frame having a sheet conveyance surface, and a shaft arranged above the sheet conveyance surface and having protrusions for correcting inclined feeding of a sheet while conveying the sheet. A plurality of supply sensors are disposed above the sheet conveyance surface at positions beyond the shaft, and in a line parallel to the shaft, for detecting presence or absence of a sheet. The sensors can also detect the size of the sheet to control the carrier of the printer to realize a random set of the sheet.
