Abstract
Abstract A paper size selection apparatus for use in copier machines with a plurality of paper accommodating sections capable of accommodating papers of different size by which one paper accommodating section is selected out from the plurality of the paper accommodating sections in accordance with an automatic paper selection function in which a preferred paper size is determined from a document size detected as well as a magnification factor, a preferential paper selection function in which a previously memorized paper size is selected, and a manual paper selection function in which a preferred paper size is selected by a key manipulation. These three paper selection functions are called for by manipulation of the key in succession and in rotation.
