Abstract

In loading a tape 1 into a tape drive having a single sprocketed capstan 2, the operator forms a short loop of tape. This he slips over the tape read head 3 and, with thumb 4 and forefinger 5, positions the tape so that its sprocket holes are engaged by the sprocket pins (not shown) on the capstan. The operator then passes his thumb and finger upward along the tape guide 6 and exerts pressure through the tape against two closure keys 7 (one only shown) mounted on opposite sides of the tape guide 6.

Tape Drive

In loading a tape 1 into a tape drive having a single sprocketed capstan 2, the operator forms a short loop of tape. This he slips over the tape read head 3 and, with thumb 4 and forefinger 5, positions the tape so that its sprocket holes are engaged by the sprocket pins (not shown) on the capstan. The operator then passes his thumb and finger upward along the tape guide 6 and exerts pressure through the tape against two closure keys 7 (one only shown) mounted on opposite sides of the tape guide 6.

Through direct mechanical linkages or indirectly through solenoids actuated by the keys 7, two closure arms 8 and 9 pivoted behind the plate 10 close around the capstan to hold the tape captive on the sprocket pins. The closure keys also release a buffer arm 11 which is spring loaded to keep the captive loop of tape properly tensioned on an idler roller 12 fixed to the arm. The tape buffer roller 12 has sprocket pins to provide lateral registration of the tape close to the work station.

If the tape breaks or runs out, the buffer arm 11 springs out to its stop position and actuates a microswitch (not shown) for machine control. Operation of a key 13 on top of the tape guide 6 causes the closure arms 8 and 9 to retract away from the capstan and the buffer arm 11 to withdraw, after which the tape falls away from the capstan.
