Abstract
A mechanism for withdrawing magnetic recording tape from a tape carrier (e.g. a cartridge) is disclosed. A boom member supports at least two levers. In the at rest (unengaged) position, rollers, supported by the levers, are positioned in a recess in the tape cartridge and are positioned interior of the tape. When activated, the boom member pivots about its pivot point, thus moving the levers attached to it. The levers move generally away from the cartridge and the rollers attached to the levers engage the tape and pull tape out of the cartridge. The roller supporting ends of the levers engage a lever guide member in such a fashion that the at least two levers move apart. In this manner, a suitable transducer mounted adjacent the lever guide member, can have tape wrapped around itself (less than 360.degree.) for subsequent recording on or playback from the tape. This mechanism is suitable for use with an internal elastic-belt-drive cartridge; when used with such a cartridge, the reels of the cartridge must be driven in their normal manner when extracting tape from the cartridge. The cartridge must also be driven in its normal manner when tape is being fed back into the cartridge. This mechanism is also suitable for use with a non internal elastic-belt-drive cartridge.
