Abstract

In an automatic paper feeder used in conjunction with an automatic typewriter or printer, the take-away rollers for ejecting the sheet from the printer must be spaced apart while the sheet is being controlled by the platen of the printer. When the printing has been completed and the sheet is ready to be ejected from the printer by the paper feeder, the take-away rollers must be snapped together and then driven in the proper direction to eject the paper. Normally, at least one solenoid and associated electronics are used to snap the take-away rollers together while a motor is used to drive the rollers.
