PURPOSE: An apparatus for examining a logic circuit of a VCR(video cassette recorder) is provided to confirm the disorder of a logic circuit in an assembling process by outputting electric signals corresponding to cassette-in, loading, play and stop of a VCR tape. CONSTITUTION: In an apparatus for examining a logic circuit of a VCR, a main circuit is connected with the logic circuit including a display panel to output control signals to display. A cam data circuit inputs working signals toward a particular driving unit to the main circuit, and a cassette-in circuit outputs signals corresponding to insertion of a cassette into a deck. In the cam data circuit, a microcomputer(206) is connected with plural connecting ports(201-205) for inputting/outputting cam data signals corresponding to a function input key of logic circuit. The microcomputer outputs response signals equal to the action of function key sequentially to the main circuit. The control signals are output from the main circuit to examine the action of logic circuit.
