Abstract
A threading mechanism in a magnetic writing/reading apparatus wherein a leader block for taking a magnetic tape out of a tape cartridge is stabilized in motion and ensured to operate reliably even in a state of not holding the tape is to be provided. In the mechanism for threading the magnetic tape to a reel within the apparatus, the leader block for taking out a leader pin out of the tape cartridge is rotatably fitted to the arm shaft of a movable arm, and the leader block moves along guides at the time of loading the tape cartridge.
Claims16
An apparatus for threading a tape wound on a supply reel and provided with a coupling element at a free end thereof, said apparatus comprising:
- a take-up reel;
- a leader block adapted to establish a connection with said coupling element of said tape and assuming one of a connected state and an unconnected state;
- a carriage transporting said leader block between a first position near said supply reel and a second position near said take-up reel through intermediate positions along a moving path;
- a shaft rotatably connecting said leader block and said carriage;
- and
- a holding element selectively engageable with and disengageable from said shaft to restrain and release rotation of said leader block with respect to said carriage depending on a state and/or a position of said leader block.
An apparatus for threading a tape wound on a supply reel and provided with a coupling element at a free end thereof, said apparatus comprising:
- a take-up reel;
- a leader block adapted to establish a connection with said coupling element of said tape and assuming one of a connected state and an unconnected state;
- means for transporting said leader block between a first position near said supply reel and a second position near said take-up reel through intermediate positions along a moving path;
- means for rotatably connecting said leader block and said means for transporting;
- and
- means for selectively engaging with and disengaging from said rotatable connecting means to restrain and release rotation of said leader block with respect to said means for transporting depending on a state and/or a position of said leader block.
A data storage apparatus for threading a tape wound on a supply reel and provided with a coupling element at a free end thereof in order to execute a read and/or a write operation on said tape, said data storage apparatus comprising:
- a take-up reel;
- a leader block adapted to establish a connection with said coupling element of said tape and assuming one of a connected state and an unconnected state;
- a carriage transporting said leader block between a first position near said supply reel and a second position near said take-up reel through intermediate positions along a moving path;
- a shaft rotatably connecting said leader block and said carriage;
- and
- a holding element selectively engageable with and disengageable from said shaft to restrain and release rotation of said leader block with respect to said carriage depending on a state and/or a position of said leader block.
