摘要： A processing control system for controlling one or more processing steps of an electrostatic printing machine of the type employing an endless photoreceptor belt and a drive motor for imparting processing movement to the belt. A photoreceptor motion sensitive element in the form of a rotatable member mounted on the drive shaft of the drive motor and a magnetic pickup device arranged to be actuated when aligned with each tooth of the gear serve to generate a plurality of control pulses. Series of these pulses, called pitch, are established by a reset arrangement, and are associated with the movement of the belt. Each series comprises a predetermined number of discrete electrical pulses some of which control machine events and processing steps.

摘要： Synchronizing apparatus is disclosed in accordance with the teachings of the present invention wherein the operation of a first device is regulated in accordance with the operation of a second device. The phase relationship between signals representing the operation of the first and second devices, respectively, is determined by comparison means which produces a pulse width modulated signal indicative of said phase relationship. Control signal generating means responds to the pulse width modulated signal to generate an analog signal having an amplitude established by said phase relationship. Feedback means, including variable frequency generating means, is controlled by the analog signal to modify the operation of the first device whereby said first device is urged into a synchronous relationship with said second device and the signals representative of the operation of said first and second devices admit of a desired phase relationship.
