Abstract
In a tape drive device of the present invention, a large number of through-holes (an sucking portion) are formed in an outer peripheral portion of a reel hub onto which a recording tape, at a free end of which a leader tape is connected, is to be wound. The leader tape is held and guided by guiding means. When the leader tape reaches the sucking portion, a suction device operates and air is sucked through the through-holes. Consequently, the leader tape is suckingly retained at the outer peripheral surface of the reel hub. With the present invention, there is no need to form depressions or projections for accommodating and anchoring the leader tape at the reel hub. Therefore, the reel hub can have a smooth structure without any steps.
Claims17
A tape drive device for winding a recording tape with a free end on a reel hub and carrying out at least one of recording of information on the recording tape and replaying of information that has been recorded on the recording tape, the tape drive device comprising:
- guiding means for guiding a tape-form leader portion to an outer peripheral surface of the reel hub, the leader portion being provided at the free end of the recording tape;
- and
- sucking means provided at the reel hub, the sucking means being capable of sucking the leader portion to the outer peripheral surface, the sucking means comprising a plurality of through-holes,
- wherein the guiding means comprises a retaining member capable of retaining the leader portion, and a moving member which supports the retaining member and moves the retaining member along a predetermined path to a portion of the outer peripheral surface of the reel hub at which the through-holes are formed.
A tape drive device for winding a recording tape with a free end on a hollow cylindrical-form reel hub and carrying out at least one of recording of information on the recording tape and replaying of information that has been recorded on the recording tape, the tape drive device comprising:
- guiding means for guiding a tape-form leader portion to an outer peripheral surface of the reel hub, the leader portion being provided at the free end of the recording tape;
- and
- sucking means provided at the reel hub, the sucking means being capable of sucking the leader portion to the outer peripheral surface;
- wherein the sucking means includes:
- at least one through-hole formed in a peripheral wall of the reel hub, the peripheral wall serving as a recording tape winding surface;
- a suction device;
- and suction piping connecting the reel hub and the suction device so as to enable passage of air therebetween, and wherein a length of the leader portion is set to a length the same as an outer circumference of the reel hub;
- and
- wherein the guiding means comprises a retaining member capable of retaining the leader portion, and a moving member which supports the retaining member and moves the retaining member along a predetermined path to a portion of the outer peripheral surface of the reel hub at which the at least one through-hole is formed.
