Abstract

An improved tape cassette adapter uses a mono-directionally operable motor having a worm rod attached to the end of the output shaft thereof that is engaged with a speed variation gear set. The last gear of the gear set having an eccentrically disposed vertical driving pole is associated with a securing board to which a limiting guide board is rotatably mounted. The limiting guide board and a left swing arm are operationally engaged with the vertical driving pole of the last gear. The limiting guide board is further engaged with a horizontally movable slide linkage rod. The likage rod is further linked to a slide board which is coupled to a pivotal right swing arm. A cam block disposed on the linkage rod is slidably in abutment against a power switch block so as to control the on and off of the motor in order to get the tape of a tape cassette stretched out or withdrawn back in operation.
