Manual/automatic paper feed mechanism in a copying machine

摘要

A copying machine includes a single paper supply roller for selectively conducting the paper supply in a manual supply mode wherein a copy paper is introduced through a manual inlet and in an automatic supply mode wherein a copy paper is supplied from a copy paper cassette. A copy paper biasing member is associated with the copy paper cassette so that the copy paper is depressed toward the operating region of the paper supply roller. A manual paper supply guide plate is rotatably secured to the copying machine so that the manual paper supply guide plate takes a first position wherein the manual paper supply guide plate is located under the paper supply roller for conducting the manual paper supply, and a second position not to interfere with the automatic paper supply from the copy paper cassette. A correlation mechanism is connected to the copy paper biasing member to disable the copy paper biasing member when the manual paper supply guide plate is located at the first position.
