Claims

[Scope of utility model registration request]

A recess is formed on the outer surface of the cassette casing to prevent accidental erasing, and a guide groove is formed on the edge of the recess so that the recess can be moved between a position where the recess is closed and a position where it is not closed.
In the accidental erasure prevention device in which a claw for preventing accidental erasure is attached to the guide groove, the core of the claw for preventing accidental erasure is configured to be elastically deformable, and the core is not formed with the recessed portion. A device for preventing accidental erasure of a tape cassette, characterized in that the guide groove is bent so as to be biased toward the inside of the cassette casing.
