Abstract: A copying apparatus has imaging equipment provided along the upstream end of a transport path for a copying sheet through its housing, and a fuser assembly including a fuser casing and a fuser heater downstream of this imaging equipment along the path. The entire fuser assembly is pivotal about a horizontal pivot in the housing from an operative position with the heater facing downwardly toward the conveyor path to a servicing position with the fuser assembly completely outside the housing and the fuser heater facing upwardly for servicing.

Abstract: A copying machine has a scanner movable in a forward direction to scan a master sheet and in a reverse direction to return to its starting position. A drive shaft of the machine rotates similarly forwardly and backwardly to displace this scanner and is connected to a pair of cams, one of which controls a pickup arm for sliding the uppermost sheet off a paper supply stack and the other of which is connected to a pair of pinch rollers which advance the picked up sheet through the imaging mechanism of the machine. Each of these cams has an operating portion which actuates the respective machine element during forward rotation of the cams, but which is brought out of engagement with the respective cam follower during reverse operation of the machine so that during return of the scanner to the starting position the pickup arm and pinch rollers are not operated.

Abstract: A sheet-holding cassette for a copying machine is formed as a box containing a stack of copy sheets. This box is adapted to be held in the machine with the uppermost sheet of the stack engageable with the paper-advance roller of the machine. A slot is provided in the upper wall of this cassette as well as a guide next to this slot and a deflector in back of this slot so that an extra sheet can be slid along the upper wall of the machine and into the cassette to lie at least at its front edge on top of the stack of sheets in the cassette. Thus as the paper-advance roller is reciprocated down onto the stack it will pick up this extra sheet rather than the top sheet of the stack, allowing a copy to be made on a single extra copy sheet without having to reload the machine.
