PURPOSE:To make the stable feed of paper performable, by driving a pulse motor with a two-phase or one-two phase exciting system during its driving, while driving the motor with a single-phase exciting system just before the stoppage. CONSTITUTION:In time of driving first and second pulse motors 14 and 21 which deliver the paper one by one with each of paper feed members 6 and 7 driven, these pulse motors 14 and 21 are driven with a two-phase or one-two phase exciting system, then clock pulses inputted from a generator 32 are counted at a driving circuit 30, and when the specified exciting phase select time is counted up, an exciting phase select pulse is outputted whereby the exciting phase is changed over to a single-phase exciting system just before these pulse motors 14 and 21 come to a stop, and when driving them at the specified rotation, these pulse motors 14 and 21 are stopped accurately. |
