ABSTRACT:
A tape threading device for a helical scan tape cassette recorder, having pivotal levers each having a tape guide for withdrawing and wrapping the tape about a guide drum. The levers overlap each other at an area of instantaneous overlap at which they are coupled to each other by a mechanism including a sliding block which is guided by a carrier device along a path which extends in the area of overlap. The sliding block is in force-sustained engagement with a link-motion surface on at least one of the levers.
