Fast search device for video cassette tape recorder - reduces length of tape in frictional contact to minimise risk of damage during high-speed movement

摘要

On one side of the head drum (11) an audio and control head (15) is mounted on a lever (17) pivoted about a screw (18) on the baseplate (10), spring-biased (19) towards the reprodn. position. A coupling pin (21) at the other end of the lever (17) constrains the head (15) to make contact selectively with tape (T) in the central pocket or recess (C1) of the cassette (C) as a connection plate (13) moves to right or left with corresp. rotation of a cam wheel (12). ADVANTAGE - The audio and control head is rotated in accordance with movement or displacement of the connection plate without drawing out the tape by means of a separate leading pin lever. The construction is simplified and risk of drawing the tape into the head is excluded.
