Abstract
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.
