Abstract
PURPOSE:To avoid variations in equimagnification, drop in resolving power, defective resist or the like by revolving several DC motors constantly in sequence following the absolute rotation position of a pulse motor while synchronizing the revolution thereof. CONSTITUTION:Drive pulses of a pulse motor are input into one input terminal of a phase comparator circuit 22 as reference pulse while output signals of a sensor 291 of an encoder 281 connected to a DC motor DM1 is input as shaped in the waveform into the other input terminal. Both the inputs are compared in the phase with a phase comparator circuit 22. A voltage according to the resultant phase difference is fed to a DC motor DM1 through a low pass filter 23, an electronic switch 24 and a driver circuit 25 to rotate it constantly synchronizing drive pulses of a pulse motor PM. Thereafter, an output of an R/S flip flop circuit 17 triggers a time constant circuit in a phase control circuit II to start a DC motor DM2 in the similar manner with the DC motor DM1.
