Claims

[Scope of Claim for Utility Model Registration] A detection hole into which a control member for preventing accidental erasure is inserted is provided in the bottom of a box-shaped cassette body that accommodates a tape reel, and the detection hole is opened in the cassette body. An erroneous erasure prevention member that is slid between an erroneous erasure prevention position where the detection hole is closed and an erroneous erasure prevention position where the detection hole is closed is accommodated, and the erroneous erasure prevention member is located inside a window provided on the side surface of the cassette body. At the same time, a protrusion for finger hooking is provided that is exposed to the outside through this window, and by hooking the tip of a finger on this protrusion and sliding the accidental erasure prevention member, the detection hole can be selectively opened or closed. In a tape cassette that can be switched to the erase position, when the accidental erasure prevention member is slid to the erase position, the fingertip can be inserted between the protrusion and the opening edge on one side of the window on the erase position side. At the same time, when the accidental erasure prevention member is slid to the accidental erasure prevention position, it comes into close contact with the other opening edge on the opposite side of the window part without any gap, and the side surface of this cassette body. A tape cassette characterized in that a notch is formed in the other side opening edge of the window and into which a jig for pressing the accidental erasing prevention member toward the erasing position can be inserted.
