Abstract
A copying machine with multiple transport functions which contains a main transport route running from a paper feed block through a copy process block to a paper discharge block, an auxiliary transport route running from the paper discharge block through reversed transport section selectively reversing copy paper being transported and an intermediate tray for storing copy paper sheets temporarily, to the paper feed block, and a multiple copy mode selector switch for making the reversed transport section effective or ineffective when copy paper is passed through the auxiliary transport route. The copying machine further includes two paper feed rollers, each driven independently and mounted on the upper and lower sides of the paper supply section of the intermediate tray, and a paper feed roller selecting switch which makes the upper feed roller drivable when the reversed transport section is made effective by the multiple copy mode selecting switch and which makes the lower paper feed roller drivable when the reversed transport section is made ineffective.
