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.
A sheet feeding cassette of a copying apparatus for supporting a stack of sheets, which is capable of receiving manually inserted sheets and which has a sheet feeding pressure applying member connected thereto, comprising:
In a copying apparatus having at least one cassette in position for carrying a stack of sheets, a feed roller for feeding one sheet at a time from the cassette in position in the copying apparatus and a pressure applying lever movable into a position for bringing the stack into engagement with the feed roller, an improvement comprising, cassette lid means movably mounted to the cassette and engageable with the pressure applying lever to move the pressure applying lever out of its position for bringing the stack into engagement with the feed roller, said cassette lid means having an upper lid pivotally mounted to the cassette so that a rear part of the lid can be moved into an open position for bringing the stack out of engagement with the feed roller when the cassette is in position in the copying apparatus, whereby a manually inserted sheet can be inserted into the cassette at the top of the stack.
An improvement according to claim 11, including, an intermediary lever pivotally mounted to the cassette and engaged with one end of the upper lid, a push-down lever pivotally mounted to the cassette and engaged with the intermediary lever and a pressure release lever connected to the pressure applying lever engaged with the push-down lever.
