  • Patent number: 7195221
    Abstract: Disclosed are a device with stabilization base and a video display apparatus. The stabilization base is movable between a use position and a storage position, and is locked in the use position so that it would not easily move. When no problem occurs even if the stabilization base is moved, the locking of the stabilization base in the use position can be canceled easily. The stabilization base (4) is movable between the use position where it is projected outwards in relation to an outer edge of a grounding portion of an apparatus main body (2) and the storage position where it is stored on the inner side in relation to an outer edge of the apparatus main body. The stabilization base in the use position is immovably locked by lock means (10), (10) provided in the apparatus main body, and the locking by the lock means is canceled by pressing from the lower side or a lateral side.
