ABSTRACT:
A sheet cutter apparatus includes circuitry for detecting when the blades of the cutter are in an "open" position with their cutting edges separted from each other, and a timer that is initiated when the blades are first opened. If the blades remain open for an excessive period of time, determined by the timer, a warning alarm is generated to remind personnel to close the blades, so that no injuries to fingers, etc., will occur.
