PURPOSE:To prevent the occurrence of the size cutting of the picture, etc., due to a calculating mistake by providing a control means to calculate the projecting magnification of an image in accordance with a detecting signal outputted from an original size detecting means and recording paper size detecting means. CONSTITUTION:When the hand supply is discriminated, in the recording paper size detecting means 35, the size of the recording paper is detected and the value is outputted to the control means 36. In the control means 36, the projecting magnification of the image is calculated based upon the recording paper size outputted from the recording paper size detecting means 35 and paper feeding cassettes 18 and 19 and the original size outputted from the original size detecting means 30. Thereafter, from the control means 36 to a lens 8, the control signal is outputted, the magnification of the lens 8 is set, and in accordance with the magnification, the copying action forming the picture at the recording paper is started. Thus, without generating the size cutting of the picture, the suitable picture can be easily formed. |
