Abstract

Apparatus for extracting a tape from a cartridge and threading it along a desired path is shown in the figures. The threading path is formed by using a combination of pulleys and a drive cable to produce the desired tape path. Referring to the figures, a drive cable 1 is wrapped around three pulleys 2, with any one of the pulleys being connected to a drive motor (not shown) to rotate the pulley and drive the cable along the path formed by the three pulleys. The cable 1 is coupled through a swivel 3 to a sliding block 4 which in turn is slidably mounted onto a polar arm 5. The polar arm 5 is pivotally mounted by a pin 6 to a top plate 7 (Fig. 2). The polar arm is supported at the other end by an outboard guide 8.

Cartridge Tape Threading Assembly

Apparatus for extracting a tape from a cartridge and threading it along a desired path is shown in the figures. The threading path is formed by using a combination of pulleys and a drive cable to produce the desired tape path. Referring to the figures, a drive cable 1 is wrapped around three pulleys 2, with any one of the pulleys being connected to a drive motor (not shown) to rotate the pulley and drive the cable along the path formed by the three pulleys. The cable 1 is coupled through a swivel 3 to a sliding block 4 which in turn is slidably mounted onto a polar arm 5. The polar arm 5 is pivotally mounted by a pin 6 to a top plate 7 (Fig. 2). The polar arm is supported at the other end by an outboard guide 8. A pickup means 9 is formed at one end of the swivel block 3 to contact a leader block 10 to pull the tape 11 from the cartridge 12. In operation, the leader block 10 of the cartridge 12 is connected to the pin 9. Power is applied to the drive motor to rotate the drive pulley 2 and thereby move the drive cable 1. The drive cable 1 will pull the swivel block and the pin 9 along its path outlined by the drive cable 1 and pulleys 2. The swivel block 3 will pull the sliding block 4 along the polar arm 5. The polar arm 5 will swivel from pivot 6 and move along the outboard guide 8 to guide the tape 11 along the path outlined by the drive cable 1. The tape 11 is passed around idler rolls and a transducer (not shown) and directed...
