PROBLEM TO BE SOLVED: To provide a controller which prevents degradation in the accuracy of clock signals of high frequencies and allows the reduction of a cost. SOLUTION: The controller 200 comprises a microcomputer 202 and a selector 204. The selector 204 includes decoders 208A, 208B, 208C, etc., and AND circuits 210A1, 210A2, 210B1, 210B2, 210C1, 210C2, etc. A timer 206 is provided with a plurality of channels Ch1, Ch2, Ch2, etc., through which clock signals of specified frequencies are outputted. A clock signal outputted through the channel Ch1 is outputted to either of a paper pull-out motor 212 and a second loop guide driving motor 214 which do not simultaneously operate by the selector 204 according to a select signal SEL1 outputted from the microcomputer 202. |
