A display apparatus is incorporated in an image-forming apparatus such as an electrophotographic copying machine. The display apparatus comprises a display device which pictorially displays component segments of said image-forming apparatus, the component segments defining at least the paper path and the outlines of the image-forming apparatus, an oscillator for producing drive pulses "A" and complementary drive pulses "B", a processor from which a data signal is derived based upon a predetermined program, a latch signal and a clock pulse signal respectively, and a display driving circuit which receives the drive pulses "A" and the complementary drive pulses "B" so as to drive the display device under the control of the data signal, whereby the processor controls the display device to display on the component segments a present position of sheets of paper in synchronism with the paper movement by calculating the clock pulse signal. |
