<p>PURPOSE:To obtain a mechanism which operates electrically the tape run system of a cassette video tape recorder with a tape mount mechanism. CONSTITUTION:In the longest recording or reproducing period, this release mechanism releases a brake interlocking with the excitation of 3rd solenoid 57 without exciting both 2nd solenoid 36 for brake release and 3rd solenoid 57 for pinchroller pressure contact. With a recording or reproducing switch closed, 3rd solenoid 57, capstan motor 50 and reel driving motor 13 are excited and solenoid 57 makes roller 46 in pressure contact with capstan 47 to turn 5th lever 61; and 3rd lever 27 only is turned without sliding 2nd slid 32 to release pressure contact between supply reel brake lever 23 and take-up reel brake lever 25, thereby running a tape fed from a supply side with constant tension at a steady speed.</p> |
