ABSTRACT:
A videotape cassette is provided with a cassette cover which is mounted on a cassette casing to be movable between a closed position and an open position and is urged toward the closed position by a closing spring. Further, the cassette casing is provided with a lock mechanism which prevents the cover from being accidentally opened when the cassette is free. The lock mechanism comprises a lock member which is movable between a locking position in which it is engaged with the cassette cover in the closed position to lock the cassette cover to the closed position, and a lock releasing position in which it releases the cassette cover, and a locking spring which normally urges the lock member toward the locking position. In order to check whether the cover can be correctly opened and closed, the lock member is first urged toward the lock releasing position and then released. Then the cover is urged toward the open position and then released. Thereafter the position of the cover is detected. Thereafter, the lock member is moved to the lock releasing position, and with the lock member held in the lock releasing position, the cover is brought to the open position and then released. Then the position of the cover is detected.
