ABSTRACT:
A mode discriminating method and apparatus for use in a deck mechanism for a video cassette tape recorder, which includes a motor for generating power for switching modes, a gear member rotated by the motor, and a slide member moved by the gear member. The slide member has an extending portion in which two cam grooves are formed. The apparatus further includes two switching devices which are interlocked into the cam grooves and a motor rotation detector for detecting the rotating direction of the motor, thereby reducing the number of switching elements for mode discrimination and simplifying the mechanism.
