Abstract of the Disclosure An apparatus for processing and viewing cassette contained film strips automatically in response to the condition of a cassette containing the film strip in accordance with programmed operational modes determined by an electro-mechanical logic stem. The logic system enables the use of a single undirectional electric motor for driving all viewer apparatus components including a programming cam disc between "off", "project" and "process/rewind" positions. A power switch organization brings about energization of the motor upon cassette insertion as well as movement of the logic disc to the off position upon a combination of cassette ejection and rotation of the camming disc to the off position. Motor oper- ation in the process mode is controlled by an electronics system controlled by a combination of the programming disc position and the conductive or non-conductive state of cassette contained contacts which correspond respectively to the unprocessed or processed state of the film strip in the cassette.
