摘要： A copier of the type which includes a photoreceptor on which an electrostatic latent image may be formed, a movable applicator which carries developer from a working supply of image developer and applies it to the image, and developer dispensing instrumentalities for replenishing the working supply of developer, is provided with a system for controlling the developer dispensing instrumentalities and thus replenishment of the working supply of developer. The control system responds to the optical density of developer on the applicator to generate a signal indicating whether or not the working supply of developer is in need of replenishment, and this signal is utilized for energizing the dispensing instrumentalities. The control system also includes circuitry for preventing energization of the dispensing instrumentalities for a predetermined time interval after commencement of movement of the applicator, to be sure that the applicator has picked up a sample of the developer from the working supply. Preferably, the control system further includes circuitry for replenishing the working supply of developer for at least a predetermined minimum time interval after replenishment is commenced.

摘要： A postal meter includes a postal meter assembly adapted to be driven from a base, for in turn driving the drum of a settable printing mechanism. The meter has an electronic accounting system with a register, and means setting the register during the printing cycle. A mechanical latch is positioned to stop rotation of the gear assembly at a home position if an electronic accounting has not occurred during the previous printing cycle. The gear assembly further includes a cam surface for driving the mechanical latch to this position following initiation of a printing cycle. A detent has a tooth selectively engageable with a pair of notches on the lever corresponding to the two lever positions, the detent being displaced in one case by a cam surface of the gear assembly and in the second case by a lever system responsive to the operation of the accounting system.
