MAGNIFICATION CONTROLLER FOR ELECTROPHOTOGRAPHIC TYPE COPYING MACHINE |
摘要 |
An electrophotographic printing machine in which a variable magnification optical system is controlled so that information being reproduced from an original document fits on a copy sheet. The size of the original document is sensed. The device sensing the size of the original document has a minimum number of detectors to measure a maximum number of different size original documents. The size of the copy sheet is compared to the size of the original document and an error signal generated indicative of the difference therebetween. This error signal controls the magnification of the optical system. |
