ABSTRACT:
A brake actuating device for use in a tape recorder such as a video cassette tape recorder and a digital audio tape recorder includes a supply brake resiliently biased by an elastic member, a brake actuating mechanism for actuating the supply brake, a reel driving mechanism for driving a supply reel and a take-up reel, selectively, a take-up reel rotation-restricting member for preventing the rotation of take-up reel in a tape unloading operation, and a restricting member for restricting the reel driving mechanism not to drive the take-up operation, thereby making it possible to prevent the tape from being excessively unwound and thus being damaged, by loading and unloading the tape with a proper tensional force.
