ABSTRACT:
In a digital copying apparatus, the digital image data of a document to be copied are stored in a memory means, and an image is copied on a paper according to the digital image data stored in the memory means. Two clear modes are provided for clearing the image data stored in the memory means. In the first clear mode, the data in the memory means is cleared when the document is detected to be removed from the platen and the like. In the second clear mode, the data in the memory means is cleared when a new document is detected to be set on the platen glass or the like. One of the two clear modes is selected with the operational panel and the selected mode is displayed. A memory clear command is sent to the memory means at an appropriate timing in the two clear modes, and the memory clear is executed by the memory means. The memory clear command is sent only after the copying operation is completed or it is inhibited to clear the image data when a latent image is being formed according to the image data.
