Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03B27/62
Filed: 1990-03-02
Abstract: PURPOSE:To record an image without specially opening a platen cover when an interruption operation is executed by providing a selection means which selects respective different ejection means when a first and a second document feeding means are used. CONSTITUTION:When the document feeder (an ADF) 4-1 is operated, a document is transferred on a platen glass 3a and a sorter bin 7-1 is left at the same time. Then, a transferred paper is classified, selected and ejected to the other sorter bins 17-2a to 17-2d through selectors 17-2a' to 17-2d'. On the other hand, when copying is executed by a document feeder (an SDF) 4-2, the document is set to a document exposure position after it is carried to the platen glass 3a. Under such a state, the transferred paper is ejected to a non-sort bin 17-1. Then, when the interruption by the SDF is executed while the ADF is operated, the interrupted document is set on the platen glass 3 and the copying action thereof is started thereafter. Besides, the transferred paper is ejected to the non-sort bin 17-1 other than the sort bins 17-2a to 17-2d by operating the ADF 4-1. Thus, the interruption is easily executed.
