It is known, especially in ordinary commercial video recorders, to use a cassette loading device with a cassette acceptance device. It is also known to lock cassettes of a given system standard by means of an engagement block engaging in a recess in the side of the casing of such a cassette away from the drive during the loading or unloading procedure. The aim of the invention is to provide a cassette lock which is not bound to a system standard. Instead of positioning pins arranged on the mechanism chassis (7) for centring a cassette (1) there are corresponding centring apertures (7a; 7b) in the chassis and pivotable positioning pins (111a; 111b) on the cassette acceptance device (10) which co-operate with the cassette loading device in such a way that, when a cassette (1) is inserted into the acceptance device (10), these pins (111a; 111b) pivot into acceptance apertures (6e; 6f) in the cassette (1), remain in engagement therewith during the loading process and, when the cassette has reached the operating position, engage with the centring apertures (7a; 7b). Cassette loading device, especially for video and R-DAT recorders. |
