<p>PURPOSE:To make it convenient to use a machine and decrease errors, by constituting the machine as conveying sheet material precedently from a sheet material loaded means which is newly set, through signals which are output when it is detected that this sheet material loaded means is set. CONSTITUTION:When a cassette 6 is loaded with copy paper 8 and set in a copying machine, an information pin 7 of this cassette 6 pushes one of microswitches 12-15, and the size of the paper 8 is input in a microcomputer 5. At the same time, transformation of signal given the moment the said one of the microswitches 12-15 is pushed, is input in the microcomputer 5. A paper-existence signal is also input in the microcomputer 5, by using an electric bulb 9, a lens 10 and a photosensor 11. This microcomputer 5 deals with the said signals according to the preset program, and controls so that the newly set cassette is precedently chosen when it is detected that this cassette is loaded with copy paper. In this system, the machine is used conveniently, and errors can be decreased.</p> |
