Abstract

A pocket-sized, solid state "key" counter unit to replace the electromechanical "Auditron" individual auditing device now used to actuate copiers upon insertions It utilizes known solid state circuitry to accumulate total copy counts in a non-volatile type of circuitry within the unit, has a LED count display and is normally powered through its insertion plug by the copier- "Non-volatile" in this context can be known solid state circuitry that retains a last-count memory sustaining power from a small self-'contained rechargeable battery pack upon removal of the unit from the copier. The LED display would extinguish automatically upon unplugging of the unit from the copier to save power. However, it could be recalled and displayed from the battery by merely pressing a recall button on the unit. A reset or "zeroing" button could also be provided.
