Abstract

In reel to reel tape drives it is essential that the end of the tape be detected when leading the tape onto a take-up reel or rewinding the tape into a loading cartridge. Failure to detect the tape end accurately can damage the drive or the tape. A simple means for detecting a tape end in a reel to reel tape drive having a guiding track is provided by positioning an optical sensor at the end of the track and attaching a flag to a tape drive threading arm. When the flag is detected by the sensor, the tape drive threading arm is then in position. A simple tape end detector is shown in the figures. Drive threading arm 1 is shown with drive pin 2 in a nesting position within nesting device 6 on guiding track 3. In this position, optical sensor 4 is activated by flag 5 attached to arm 1.

Nesting Device for Tape Drive Threading Mechanism

In reel to reel tape drives it is essential that the end of the tape be detected when leading the tape onto a take-up reel or rewinding the tape into a loading cartridge. Failure to detect the tape end accurately can damage the drive or the tape. A simple means for detecting a tape end in a reel to reel tape drive having a guiding track is provided by positioning an optical sensor at the end of the track and attaching a flag to a tape drive threading arm. When the flag is detected by the sensor, the tape drive threading arm is then in position. A simple tape end detector is shown in the figures. Drive threading arm 1 is shown with drive pin 2 in a nesting position within nesting device 6 on guiding track 3. In this position, optical sensor 4 is activated by flag 5 attached to arm 1. The presence of flag 5 within sensor 4 stops motion of arm 1 and locks the tape end (not shown) in place on a take-up reel or tape cartridge. Connector 7 and flat cable 8 carry the signal from sensor 4 to a tape cover interlock consisting of female connector 9 attached to the tape deck 10 and male connector 11 attached to tape deck cover
12. Flat cable 8 is actively connected when the cover 12 is closed. All nesting devices 6 are identical and can be mounted at either end of track 3. The devices 6 are also readily adjustable after being positioned in guide 3. Bore 15 in cover 12 enables an eccentric tool to extend through the cover 12...
