<p>PURPOSE:To obviate the necessity of the electric wiring for drive-controlling each pair of transfer rotary bodies by determining the drive transmission direction of each one-way clutch in order to transmit the driving force to a pair of the first transfer rotary bodies in case of the normal revolution of a driving source, while transferring the drive force to a pair of the second transfer rotary bodies in case of the reverse revolution. CONSTITUTION:When a sheet motor is driven in the clockwise direction (normal direction), the drive is transmitted to a transfer roller 3a, keeping a resist roller 4a in a stop state, and at the same time, the feed of the sheet P in a cassette 1 is started by the revolution of a feeding roller 2 in the state where the hook of a solenoid is released. The sheet P is transferred by a pair of transfer rollers 3a and 3b, and intruded into the nip parts of a pair of resist rollers 4a and 4b in stop, and a loop is formed gradually on the sheet P. When the sheet motor is revolved reversely, the drive is transmitted to the resist roller 4a, keeping the transfer roller 3a in stop state, and the sheet P is transferred to a copying fixation part by the revolutions of a pair of resist rollers 4a and 4b.</p> |
