Tape drive apparatus, tape extraction apparatus and tape cassette

Abstract

The invention proposes a tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge. The invention is constituted by a magnetically recording/reproducing apparatus; a cartridge mount mechanism 5 whereon a tape cartridge 4 with the magnetic tape T wound therein is mounted; a takeup reel 3 to wind up magnetic T thereon; a leader block 12 attached to one end of the magnetic tape T with a rotation restriction section provided thereon; a chucking mechanism 14 which comprises a chucking pin 27 that restricts the rotation of the leader block and chucks the leader block 12, chucking and releasing chucking of the leader block 12; a carrying mechanism 11 which comprises the carrying section 13 for carrying the chucked leader block 12; a chucking release levers 33 and 34 which releases chucking of the chucking mechanism 14, which is actuated by cams 35 and 36 provided on the carrying section 13 and disposed on both ends of the cam groove 19 for guiding the movement of the leader block 12; and reel motors 53 C and 53 T including frequency generators 52 C and 52 T for rotationally driving the tape reel 410 within the tape cartridge 4 and the takeup reel 3, respectively.

       5 . A tape drive apparatus for recording and/or reproducing information on a magnetic tape extracted from a tape cartridge, comprising: a carrying mechanism for extracting said magnetic tape as a recording medium, from said cartridge where the magnetic tape is stored, and for carrying the magnetic tape to be wound up onto a takeup reel provided on the drive apparatus, characterized in that said carrying mechanism comprises: 
 a carrying section engaging with a leader block provided at the end of said magnetic tape, and carrying the leader block between said cartridge and said takeup reel;    a detection means for detecting the status of engagement of said leader block with said carrying section; and    a control means for controlling said carrying section to re-attempt engaging with said leader block, in response to the detection result of said detection means.    
   
   
       6 . The tape drive apparatus according to  claim 5 , wherein 
 said detection means is construed with a chucking sensor that detects the chucking status with said leader block of the chucking mechanism.    
   
   
       7 . The tape drive apparatus according to  claim 5 , wherein 
 said takeup reel and a tape reel of said cartridge are driven by respective reel motors comprising frequency generators, respectively; and    the outputs of said frequency generators are detected either as normal or not normal to verify the status of carrying a magnetic tape.
