Paper feed rolls 3a and 3b that feed copy paper from each paper feed cassette 1a+1b, and paper feed slots 3a and 3b.
Paper guide 4 that guides the copy paper fed by
a g 4 b + 4 e, a manual feed roll 5 that feeds the paper manually fed from the manual paper feed slot 2 via the paper guide 6, and a conveyor that conveys the paper fed from each guide in the transfer direction. In the above configuration, in the normal copying mode, the paper feed roll 3M or 3b is driven to feed the paper feed cassette 1a or 1.
In the manual copying mode, paper is fed from the manual paper feed port 2, so that copying operations can be performed. Moreover, since the manual feed roll 5 is shielded by the paper guide 4&, the copy paper fed from the paper feed tray la is guided to the transport roll 7 by the manual feed roll 5 without being disturbed in its running.
