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.

Dependent claims

In a cassette tape transport receptive of a tape cassette and of the type having a read/record head, an actuating plate carrying said head and means mounting said actuating plate for movement into and out of an operating position wherein said head is brought into engagement with a run of tape in the cassette, means mounting said head on said actuating plate for universal adjustment with respect to the run of tape comprising;

a positioning plate;
means mounting said positioning plate to said actuating plate for movement towards and away from run of tape and wherein said actuating plate is disposed between said head and said positioning plate;
and
means mounting said head to said positioning plate comprising at least three first clearance holes in said actuating plate,
at least three adjusting screws connecting said head to said positioning plate and each freely passing through one of said first clearance holes and
spring means biasing said head away from said actuating plate and comprising
a leaf spring having a central section and at least three arms each engaging said head adjacent to the adjusting screws and
means coupling the center of the leaf spring to the positioning plate comprising a second clearance hole in said actuating plate and a ball positioned between said leaf spring and said positioning plate and having a diameter to freely pass through said second clearance hole and to maintain said leaf spring clear of said actuating plate.
