Abstract
A reel base braking mechanism for a reel base of a video tape recorder in which the number of assembly parts can be reduced and an accurate braking timing can be obtained by employing a so-called one-way mechanism using a plane cam. In a ganged relation with a slide operation of a slide plate on which a plane cam formed of first and second guide grooves is formed when a tape loading and tape unloading are carried out, a pin of a braking arm is selectively engaged with the first and second guide grooves to rotate the braking arm to control the timing at which said supply-reel base is operated with brakes-on and off.
