Claims
- 1. In a tape cassette player having a rotatable tape supply reel base including means for lockingly accepting a supply reel thereon, a rotatable takeup reel base including means for lockingly accepting a takeup reel thereon, a takeup reel base drive motor means for driving said take up reel base to wind a tape thereon from said supply reel, a magnetic reproducing head, head shift means for moving said head from a retracted position to allow cassette insertion to a forward tape-contacting position after such insertion, and means for automatically energizing said drive motor to urge said takeup reel base in a tape-advancing direction attendant to insertion of said cassette, the improvement comprising:
- brake means for releasably locking said tape supply reel base against rotation caused by said urging of said takeup reel, said brake means including means responsive to the position of said head shift means for operating said brake means to a locking state when said head is in said retracted position and for operating said brake means to an unlocking state after movement of said head to a tape-contacting position, so that the tape is tensioned by said motor means and immobilized by said brake means prior to the release of said brake means.
- 2. The system as set forth in claim 1 wherein said brake means includes:
- a movable slide plate operatively linked to said head shift means so as to be moved between advanced and retracted positions responsively corresponding to movement of said head between said tape-contacting and retracted positions thereof;
- a stopper carried on said slide plate;
- an indented wheel affixed to said tape supply reel base;
- said stopper and said indented wheel being provided with portions configured for lockingly engaging each other with said slide plate in said retracted position and for disengaging upon movement of said slide plate during said movement of said head to said tape-contacting position.
- 3. The system as set forth in claim 2 wherein said slide plate carries a pivotal link thereon, said stopper being formed on said pivotal link.
- 4. The system as set forth in claim 3 wherein a spring means is provided coupled between said pivotal link and said slide plate for biasing said stopper toward a position for engagement with said indented wheel.
