ABSTRACT:
The safety device for tape cassettes for the positionally correct insertion of the tape cassettes into an acceptance device comprises a tongue-shaped spring element disposed at the floor of the acceptance device, a ramp edge being disposed at the free end of said spring element, with said ramp edge cooperating with the front edge of said tape cassette and being displaceable by said front edge out of the insertion region upon insertion of said tape cassette. A stop piece engaging behind the ramp edge in the direction toward the fastening end of the spring element is connected to the ramp edge, the stop piece interacting with a recess of the tape cassette such that, given positionally correct insertion of the tape cassette into the acceptance device, the stop piece first slides into the recess and, upon continued insertion of the cassette, the front edge thereof displaces the stop piece out of the insertion region via the ramp edge. Upon improper side-inverted insertion of the tape cassette, the cassette can only be inserted up to the stop piece.
