Abstract
Abstract A tape extractor for automatically extracting a magnetic recording tape from a tape reel cartridge; the extractor has a retractable coiled metal or plastic band with a hook at its distal end which enters a single reel magnetic tape cartridge and hooks into the leader of a magnetic tape and withdraws the tape leader to a point at which the leader is engaged by a drive capstan and pinch roller and is automatically withdrawn from the extractor hook and fed through the recorder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
An automatic tape extractor for extracting a tape from within a partially enclosed tape reel, the tape having an attached tape leader with a slot near its distal end, the extractor comprising: a. an elongated band having a hook at its distal end; b. first drive means, including a reversible electric motor, operably connected to said elongated band for extending and retracting the end of said band; c. second drive means operably connectable to a tape reel for rotating a connected tape reel in at least a windup direction; d. guide means for guiding said band into the periphery of a tape reel connected to said second drive means; and e. first activating means for activating said first drive means and extending said band along said guide means.
Claim 2
Dependent Claim
128 words
An automatic tape extractor for extracting a tape from within a partially enclosed tape reel, the tape having an attached tape leader with a slot near its distal end, the extractor comprising: a. an elongated band having a hook at its distal end; b. first drive means, including a reversible electric motor, operably connected to said elongated band for extending and retracting the end of said band; c. second drive means operably connectable to a tape reel for rotating a connected tape reel in at least a windup direction; d. guide means for guiding said band into the periphery of a tape reel connected to said second drive means; and e. first activating means for activating said first drive means and extending said band along said guide means.
Claim 3
Dependent Claim
61 words
The tape extractor of claim 1 further comprising detection means for detecting an engagement of the hook of said band with a slot on a tape leader attached to a tape in a partially encloses tape reel connected to said second drive means and rotated in a windup direction, when said band is extended into the periphery of the tape reel.
Claim 4
Dependent Claim
30 words
The tape extractor of claim 2 further comprising means responsive to said detection means and operably connected to said second drive means for stopping rotation of a connected tape reel.
Claim 5
Dependent Claim
32 words
The tape extractor of claim 3 further comprising means responsive to said detection means for reversing said first drive means to retract said band and extract an engaged tape leader and tape.
Claim 6
Dependent Claim
67 words
The tape extractor of claim 4 further comprising means for disengaging an extracted tape leader from said band. 6. The tape extractor of claim 5 wherein said first drive means comprises a flanged drum on which said band is wound said drum being connected to a concentrically arranged gear by a pin and elongated slot connection, and said gear being operably connected to said reversible drive motor.
Claim 7
Dependent Claim
89 words
The tape extractor of claim 6 wherein said detection means comprises a first switching means and a second switching means so constructed and arranged that said first switching means stops the extension of the band when extended a predetermined distance, and said second switching means reverses the drive motor of said first drive means and disengages said second drive means when said band has engaged a tape leader and has been further extracted a predetermined distance by said second drive means through interaction of said pin and slot connection.
Claim 8
Dependent Claim
67 words
The tape extractor of claim 7 wherein said means for disengaging an extracted tape leader from said band comprises selective guide means to divert the end of an extracted tape leader from said band and tape transport means for engaging the end of a tape leader and transporting an engaged tape leader at a speed greater than the speed of said first drive means retracting said band.
