ABSTRACT:
A new mode detecting apparatus for video cassette recorder which is capable of linearly directly controlling the mode position is disclosed. A light emitting diode is installed under a main deck. A mode driving plate is provided with a plurality of holes for selectively passing the light from the light emitting diode. The light which have passed through the holes of the mode driving plate are sensed by photo transistors which then generates electrical signals. The signals are sent to a microcomputer which then detects the mode of the deck. The constitution of the gears is simplified, and the mode can be recognized and controlled by the mode driving plate directly and linearly.
