Abstract
A mechanical counting device for use in office machines such as copying machines in which almost all of the operative structure has been integrated into a single component. The surface works in conjunction with a ratchet pawl to count down from a preselected number, the number of completed cycles performed by the office machine. The counter energizes and de-energizes the office machine's operation at the start and finish respectively of this preselected number of cycles. In addition the counter includes a position for the continuous operation of the office machine without counting, and the capability to stop the operation of the office machine without disrupting the counting sequence.
