Abstract
A tape leader block can be restored to and removed from its housing in a tape cassette by a device which comprises a threader arm having a leader block carrier which supports a threader pin. The leader block carrier also is provided with a gear system which engages with a compatible gear system of a rotatable yoke. The yoke terminates in a cam follower which is forced into certain distinct operating positions by powered movements of a camming device. Attainment of these operating positions serves to restore or remove the leader block to and from the tape cassette's leader block housing.
