Abstract

PURPOSE:To make the copying paper housed inside a cassette body so as not to be affected by dust and other foreign substances at all, by making a cover part, which is installed in the cassette body free of opening or closing, into a state of being opened by means of a copy start signal, in a state of loading a copying machine body with the cassette. CONSTITUTION:At the cassette insertion part of a copying machine body loaded with a cassette device carrying a cover part on-off mechanism, there is provided with a cover part driving device 10 for sliding a cassette cover part 4 against resilient force of a spring 8 in time of copy starting and making an opening part 2 of a cassette body 1 into a state of being opened. When a cassette is loaded onto the copying machine body, the cover part 4 is left intact as closing the opening part 2 by action of the spring 8. Then, when a copy start signal is emitted, a solenoid 15 is energized to operate and thereby attracts a plunger 14 so that a lever 13 rotates as centering on a shaft 12 in an arrow A direction. Therefore, the cover part 4 is forced to move in an arrow B direction, making the cassette opening part 2 into a state of being opened, thus copying paper 9 is made to get fully prepared for paper feeding achievable.

Description

部に不鮮明部分が生じ、複写むらが発生する。Therefore, in a place with a bad environment, dust etc. tend to adhere to the surface of the copy paper stored in the cassette, and if copying operations are performed under such conditions, the paper feed roller and photoreceptor made of elastic material may become dirty. or cause damage. In addition, because the paper feed opening is formed large, in humid locations, the upper sheets of copy paper stored in the cassette will absorb moisture, especially the portion located in the cassette opening. When copying is performed using copy paper in such a state, blurred portions occur in some areas, resulting in uneven copying.
