ABSTRACT:
An automatic film processor sets new reference developer chemical temperatures and film transport speeds in accordance with user input at a keypad and establishes a new delay time to provide constant fixed spacing along the transport path between trailing edge of one film sheet and leadfing edge of a next film sheet regardless of transport speed. "Wait" and "ready" lights are controlled to signal when a next sheet is to be fed. A microcomputer calculates the delay time and loads a counter. A buzzer signals countdown to zero.
