ABSTRACT:
This apparatus is used for recording and/or playing back a magnetic tape contained in a cassette provided with a hole for receiving a capstan roller and edge apertures for receiving a pressure roller adapted to press the tape against the capstan roller and a recording and/or reading head. The pressure roller is rotatably mounted between two parallel support levers which are pivotally mounted on the base about the same pivotal axis. A third lever pivoted about the said axis is coupled to the support levers by a lost motion coupling allowing limited relative pivotal mouvement between the support levers on the one hand and the third lever on the other hand. This apparatus further comprises a single actuation member which is movably mounted on the base to move the third lever to a position in which the pressure roller is moved into its position of engagement.
