Abstract
In a tape drive device of the present invention, a window portion, through which a leader pin attached to a distal end of a magnetic tape can pass, is provided in a reel hub for winding the magnetic tape. The leader pin is fed into the reel hub through the window portion and is accommodated and held at an accommodation recess portion of a clamp member. The clamp member holds the leader pin and is rotated a half-turn inside the reel hub. Then, a closing portion is advanced into the window portion. A distal end surface of this closing portion is formed in a circular arc shape in accordance with an outer peripheral surface of the reel hub. Together with the outer peripheral surface of the reel hub, the distal end surface structures a winding surface around which the magnetic tape is wound.
Claims24
A tape drive device that winds a recording tape, which is provided with a leader member at a distal end portion thereof, at a winding reel while carrying out at least one of recording of information to the recording tape and replaying of information that has been recorded to the recording tape, the tape drive device comprising:
- a hollow reel hub which structures the winding reel and includes an outer peripheral surface which constitutes a winding surface for the recording tape;
- a window portion formed penetrating through a peripheral wall of the reel hub, the leader member being passable through the window portion;
- and
- a closing member disposed entirely within the reel hub, the closing member being advanceable and withdrawable with respect to the window portion and, when the leader member has entered into the reel hub, the closing member advancing from within the reel hub to the window portion and structuring a portion of the winding surface.
A tape drive device that winds a recording tape, which is provided with a leader member at a distal end portion thereof, at a winding reel while carrying out at least one of recording of information to the recording tape and replaying of information that has been recorded to the recording tape, the tape drive device comprising:
- a hollow reel hub which structures the winding reel and includes an outer peripheral surface which constitutes a winding surface for the recording tape;
- a window portion formed Penetrating through a peripheral wall of the reel hub, the leader member being passable through the window portion;
- a closing member disposed in the reel hub, the closing member being advanceable and withdrawable with respect to the window portion and, when the leader member has entered into the reel hub, the closing member advancing to the window portion and structuring a portion of the winding surface;
- a driving mechanism for driving the closing member, wherein the closing member comprises a portion for holding the leader member and a distal end surface portion which structures a portion of the winding surface in a state in which the closing member has advanced to the window portion, and wherein, when the leader member has arrived at the leader member holding portion through the window portion and is held by the holding portion, the closing member is driven by the driving mechanism and the distal end surface portion advances to the window portion.
A tape drive device that winds a recording tape, which is provided with a leader member at a distal end portion thereof, at a winding reel while carrying out at least one of recording of information to the recording tape and replaying of information that has been recorded to the recording tape, the tape drive device comprising:
- a hollow reel hub which structures the winding reel and includes an outer peripheral surface which constitutes a winding surface for the recording tape;
- a window portion formed penetrating through a peripheral wall of the reel hub, the leader member being passable through the window portion;
- a closing member disposed in the reel hub, the closing member being advanceable and withdrawable with respect to the window portion and, when the leader member has entered into the reel hub, the closing member advancing to the window portion and structuring a portion of the winding surface,
- further comprising a driving mechanism for driving the closing member, wherein the closing member comprises a portion for accommodating the leader member and a distal end surface portion which structures a portion of the winding surface in a state in which the closing member has advanced to the window portion, and wherein, in a state in which the leader member is accommodated at the leader member accommodating portion, the closing member is driven by the driving mechanism such that the distal end surface portion advances to the window portion while the leader member remains accommodated at the leader member accommodating portion.
A tape drive device for winding a recording tape, which is provided with a leader member at a distal end portion thereof, at a winding reel, the tape drive device comprising:
