ABSTRACT:
A copying machine has a simultaneous color mode for forming multi-color images in a single copy cycle and especially selects and releases the simultaneous color mode. An index, which is movable in the scanning direction of a document, is operated to automatically select the simultaneous color mode and set the switching position thereof. In addition, the index is moved out of a document area to automatically release the simultaneous color mode, which enables the simultaneous color mode to be easily selected and released. As a result, the miscopying of a document caused by a mistaken operation in selecting or releasing the simultaneous color mode can be prevented.
