Paper feeding cassette case in image forming apparatus

摘要

A paper feeding cassette case in an image forming apparatus according to the present invention is so adapted that an arbitrary internal unit out of a plurality of types of internal units including at least one internal unit of a universal type having a structure in which paper sheets of a plurality of sizes requiring the switching of the printing ranges can be set can be attached thereto. In the paper feeding cassette case, detecting member mounting portions are respectively formed in different positions respectively corresponding to the types of internal units, and the detecting member and each of the detecting member mounting portions are provided with mounting member for detachably mounting the detecting member on the detecting member mounting portion. In addition, the mounting member provided for the detecting member mounting portion corresponding to the internal unit of a universal type has a structure in which the detecting member is allowed to slide in the range of the detecting member mounting portion.
