摘要

A sheet-accommodating cassette includes a cassette body for accommodating sheets. The cassette body is made up of a main container and a sub container. Both the main container and the sub container have a plurality of engagement portions which enable them to be coupled to each other at one of a plurality of positions selected according to the size of the sheets to be accommodated. A sheet-accommodating cassette, which is formed by coupling the main container to the sub container in such a manner that the cassette can accommodate sheets of a large size, is housed in an image-forming apparatus body with part of the cassette protruding from the image-forming apparatus body.
