Facsimile apparatus using a single bi-directional motor to control

Abstract

The apparatus for feeding recording paper according to the present invention includes a platen roller gear, a white roller gear, a forwardly/reversely rotatable motor, a gear train connected to the motor, a relay mechanism for transmitting a force from the gear train to the platen roller gear and white roller gear, and a switching mechanism. The relay mechanism has a driving gear constantly meshed with an output gear of the gear train, and a first driven gear constantly meshed with the driving gear and being capable of revolving around the gear. The relay mechanism has a second driven gear constantly meshed with the driving gear and being capable of revolving around the gear. The relay mechanism has a third driven gear constantly meshed with the first driven gear and being capable of revolving around the first driven gear. The switching mechanism stops movement of the first driven gear and releases the stop of movement. By combining the switching operation of the switching mechanism and the switching of rotational direction of the motor, a torque is transmitted to at least one of the platen roller gear and white roller gear via the relay mechanism, whereby paper can be fed in the transmission, reception and copy operation modes by a single motor and recording paper can be fed backwards in the reception and copy operation modes.
