  • Protection device for a computer diskette drive
    Patent number: 5268809
    Abstract: A protection device for a diskette drive of a computer includes an access prevention member locatable in an access opening of the diskette drive and operable to inhibit insertion of a diskette into the diskette drive. Locking means retains the access prevention member in the access opening of the diskette drive. The locking means includes an arm having at its leading end a transversely extending engagement formation. The arm is rotatably mounted relative to the access prevention member thereby to permit rotation of the arm from an inoperative position while the device is inserted into the access opening of the diskette drive to an operative locking position once inserted into the access opening where the engagement formation engages a drive mechanism of the diskette drive.
