Filed: 1979-05-22
Abstract: PURPOSE:To process and control digital signals effectively by generating a synchronizing signal, following up cycles of an input signal proportionally at a fixed position in one cycle of the input signal by generating a coincidence signal by comparing the output of a voltage-dividing circuit with that of a memory circuit. CONSTITUTION:Integrating circuit 2 converts an input signal into a saw-tooth wave by integrating each period, the maximum of the output of circuit 2 is stored 3 at every time of the synchronization of the circuit output and voltage-dividing circuit 4 voltage-divides the output of circuit 3 by a predetermined rate and geneates an output. Here, the output of circuit 4 is compared 5 to that of circuit 3 and when the both agree with each other, a coincidence output is generated. At a fixed position in one cycle of the input signal, a synchronizing signal is generated which follows up the period of the input signal proportionally. Consequently, the processing of, control over, etc., digital signals such as the generation of a timing signal at a random position in one period can effectively be performed.

Filed: 1988-03-17
Abstract: PURPOSE:To miniaturize a driving torque, and also prevent the generation of squeaking between a cleaning part and an image carrier by providing the cleaning part with a constitution where a rotating blade formed spirally with india rubber is made to come into contact with the image carrier. CONSTITUTION:Untransferred toner 2 is moved in the direction of an arrow A, retaining on the surface of a photosensitive drum 1. When untransferred toner 2 moves through the area of a nipple width L generated by the rotating blade formed spirally coming in contact with the photosensitive drum 1, while the photosensitive drum 1 moves through the nipple width L, the blade 3 is rotated stripping off the untransferred toner 2 by abrading with an edge of the blade 3. Thus the driving torque of the photosensitive drum can be minimized and oscillation of a common mode in the contact part between the photosensitive drum and the rotating blade becomes difficult to generate, preventing squeaking by resonance.
