Cassette supply apparatus

摘要

A cassette supply apparatus wherein cassettes that hold documents are stacked in the vertical direction and stored in a cassette holding stacker. When a cassette is supplied to an image reading apparatus the lowermost cassette stored in the cassette holding stacker is coincident in height with a cassette supply port of the image reading apparatus and when the cassette is returned from the image reading apparatus a cassette discharge port is coincident in height with the uppermost cassette in order to return the cassette on the uppermost cassette stacked in the cassette holding stacker on the basis of the discriminated position. In case that a take in-and-out port of the image reading apparatus serves both as the cassette supply port and the cassette discharge port and when the cassette is supplied to or returned from the image reading apparatus the lowermost or uppermost cassette stored in the cassette holding stacker is coincident in height with the cassette take in-and-out port of the image reading apparatus, respectively.
