PURPOSE:To obtain this controller which can use even a CPU having a few analog input ports by inputting an original size detecting signal and an original density detecting signal into the analog input ports of the same CPU, and carrying out input processing by switching two signals in time sequence. CONSTITUTION:When an exposing lamp 23 is turned on, a first mirror unit 26, and a second mirror unit 27 are moved, and an original size detecting (APS) sensor 72 and an image density detecting (EE) sensor 70 start to detect the information of a coloring stripe 71 and the image surface of an original D. At this time, the digital output ports O7, and O8 of the CPU 100 are at L- and H-levels, respectively and the output of the APS sensor 72 is inputted into the analog input port I8. When the APS sensor 72 reaches the original D, the levels of the output ports O7 and O8 of the CPU 100 are switched, and the output of the EE sensor 70 is inputted into the input port I8 of the CPU 100. |
