Abstract
Abstract A mounting base to support and position a magnetic tape cassette on the chassis of a video tape recorder consists of a generally rectangular plate in which the supports for the cassette consist of marginal portions of the plate which are partially severed from the remainder of the plate and upwardly bent to contact the bottom of the cassette. The cassette is of the type in which the tape is carried by a pair of spools, and has an upwardly tiltable lid along one side to allow the tape to be withdrawn from operation. The cassette is first received in a mounting case which is vertically tiltably mounted on the recorder chassis. Spaces are provided in the base for the driving reels and the tape withdrawal mechanism of the recorder and when the case moves the cassette downwardly, the upwardly bent portions of the base plate flip open the lid and also properly level the cassette.
