Abstract
An apparatus of generating control signals for an electrophotographic copying machine which is provided with a disk fixed to a rotary shaft of a photosensitive drum and having through-holes formed therein, a light emitting device arranged to be opposed to a photosensitive device through the disk to form binary coded light signals and a decoder connected to the photosensitive device to decode the light signals therefrom. As the disk rotates together with the photosensitive drum, the photosensitive device sequentially senses a plurality of binary coded light signals to operate desired devices of the electrophotographic copying machine.
