<p>PURPOSE:To facilitate the residual quantity detection of paper as well as to make a cassette inexpensive and lighter in weight, by making the paper feeding cassette a throwaway one made of paper at the time of supplying cut paper to an image recorder, and installing a sheet of colored discriminating paper for residual quantity detection, in the bottom. CONSTITUTION:When a paper feeding cassette is used, first an adhesive tape on a case part 1 of packing material is removed, a cover part of the packing material is taken off, and it is attached to an image recorder. When the paper feeding cassette is attached to the image recorder, cut paper 4 and thick paper 5 are pushed upward by a spring 6 and a support plate 7, and they are fed to the inside of a device by rotation of a paper feed roller 8. The cover part of the packing material and the case part 1 both are formed with an inflammable such as paper or the like, whereby the cover part and the case part 1 are incinerateable when the cut paper 4 has been used up. During paper feeding at the image recorder, when the cut paper 4 inside the cassette runs short and a sheet of discriminating paper colored to the side is fed by the paper feed roller 8, a detector 5 detects the coloration, transmitting it to a central processing unit 10, so that a display unit 11 displays the residual quantity.</p> |
