Abstract
The utility model relates to a front entering type cassette positioning, loading and unloading device for a magnetic tape machine, which comprises a bottom seat, a cassette slide plate, a cassette clamping arm, a cassette clamping roller, a cassette spring piece, a cassette conducting base, a keying slide plate and a clamp hook device of the keying slide plate. When a magnetic tape cassette is pushed in a machine body, the cassette slide plate is driven to contact with a keying slide plate clamp hook and then escapes, so that the keying slide plate is sprung out, the cassette clamping arm is rotated, and the cassette v roller tightly clamps the cassette and is positioned on the conducting base. When the cassette is withdrawn, the clamping roller is spread only by pressing the keying slide plate. The cassette can be sprung out from the machine body by the cassette slide plate so as to reduce the volume of the loading and unloading device, and moreover, the utility model has the advantages of simple structure and easy installation and can reduce cost.
