Claims

[Scope of utility model registration request]

A cassette housing consisting of a case divided into upper and lower halves in the thickness direction, with an opening formed in at least one of the upper case and the lower case into which a recording or playback head is inserted; a disk-shaped recording medium rotatably housed in the cassette housing; a shutter movably attached to the cassette housing to open and close the opening; and a shutter disposed inside the cassette housing, the shutter constantly opening the opening In a disk cassette comprising a spring member that applies a biasing force in a closing direction, the shutter is formed in a U-shape, is arranged so as to clamp the cassette casing in the thickness direction, and extends integrally from the shutter. A locking piece passes through a through groove formed in the side wall of the cassette case, and the tip of the locking piece constantly engages with the spring member, and also prevents the shutter from falling out of the cassette case. A disk cassette characterized in that a guide plate is provided on the side wall of the cassette housing so as to cover the groove.
