PURPOSE:To control a second motor immediately so as to cope with the fluctuation of the rotating speed of a first motor even when the fluctuation of rotation is generated in the first motor, by a method wherein the rotation of the second motor is controlled based on a pulse corresponding to the number of rotation of the first motor. CONSTITUTION:An operation signal C for rotating a main motor 1 is outputted from a control circuit 4 to a drive control circuit 2. When the rotation of the main motor 1 is started, a pulse signal A, synchronized with the rotating speed of the motor, is outputted from the drive control circuit 2. The pulse signal A is introduced into a pulse divider 3 and is inputted into the control circuit 4 as a signal B, divided into a frequency optimum to copying operation. When an operation signal D is sent from the control circuit 4 into a driving circuit 5, the drive circuit 5 recognizes the pulse signal A as a reference clock and rotates a stepping motor 6 in a speed in accordance with the frequency of the clock. |
