Abstract

The threader pin used to pick up a leader block from a tape cartridge to thread the tape through a complex tape path can be connected to a coupling device that joins the ends of the guide tape as well as providing a support for the threader pin. The nut for the screw that fastens the coupling device to the guide tape can include elongated sections that contact the inside of the guide track to stabilize the coupling device.

Magnetic Tape Threader Using a Guide Tape Contained Within a Channel

The threader pin used to pick up a leader block from a tape cartridge to thread the tape through a complex tape path can be connected to a coupling device that joins the ends of the guide tape as well as providing a support for the threader pin. The nut for the screw that fastens the coupling device to the guide tape can include elongated sections that contact the inside of the guide track to stabilize the coupling device.

Fig. 1 shows the details of a channel 1 containing the sprocketed guide tape 2. The channel 1 and the guide tape 2 are part of an automatic threading apparatus for a magnetic tape transport. The channel 1 is shaped to conform to the shape of a complex tape path extending from a supply reel to the take-up reel of the magnetic tape transport. The guide tape is driven by a sprocketed gear to move it in sliding engagement with the continuous channel in either direction. The guide tape in turn moves a leader block 3 by way of a coupling device 4 through a pin 5. The end of the magnetic tape 6 is suitably fastened to the leader block 4. The channel 1 is provided with upper and lower slots 7 and 8, respectively, in which the guide tape 2 is disposed. The slotted portions of the channel 1 are held in alignment by an integral back portion 9 shaped to provide the necessary rigidity to the channel 1 and allow for means, such as the nut 10 of Fig. 2, for connecting the coupling device 3 t...
