ABSTRACT:
A copier capable of producing simplex and duplex copies includes an inverter that has constantly rotating input and output rollers mounted for pivotal movement into and out of engagement with a reversibly rotatable sleeve that is mounted on a stationary shaft. When inversion of a sheet is required, a shiftable gate deflects the sheet into a nip formed between the input rollers and the rotatable sleeve. A sensor senses the trail edge of the sheet and through a controller causes a reversible drive motor to pivot the input rollers out of engagement with the sleeve while simultaneously placing the output rollers into driving engagement with the sleeve. The sheet is then driven by the output rollers out of the inverter and back into the paper path of the copier for further processing.
