Abstract
A sheet feeding cassette which is capable of receiving manually inserted sheets is disclosed to eliminate the need to provide a copying apparatus with a device for receiving manually inserted sheets when the copying apparatus uses a sheet feeding cassette for sheet feeding. For readily receiving manually inserted sheets when the cassette is in position in the copying apparatus, the cassette includes a pressure plate responsive to the action of a sheet feeding pressure applying member, an upper lid capable of opening and closing even when the cassette is in position in the copying apparatus, and a member operative to cause the sheet feeding pressure applying member to act or stop its action in conjunction with the opening and closing of the upper lid. Sheets other than those which are usually contained in the cassette can be readily and positively manually fed readily and positively to the copying apparatus as desired for the purpose of producing copies.
