Abstract: A remote-control-operated locking/unlocking system includes a key which transmits a locking/unlocking signal by remote control. A locking/unlocking unit is provided with a controller for controlling a locking/unlocking operation based on a locking/unlocking signal transmitted from the key. The controller has a suitability determining section for determining the suitability of a locking/unlocking signal transmitted from the key, and an information section for providing information indicating that the use of the key is unsuitable.

Abstract: A transmission and reception system for controlling a locking/unlocking operation of a key includes a transmission section for transmitting a control signal having a predetermined frequency for effecting locking/unlocking of the key, and a reception section for receiving the control signal and effecting driving control of the key in response to the control signal. The reception section includes a carrier detection circuit for detecting a frequency of the control signal and supplies power only to the carrier detection circuit when the control signal is not received.

Abstract: A built-in camera type video tape recorder can be loaded on a connecting apparatus for connecting the built-in camera type video tape recorder having video signal, audio signal, and control signal terminals and a power supply connecting terminal to other electrical machinery and apparatus. It comprises a supporting member formed at one side wall of the built-in camera type video tape recorder and having a shutter member, the shutter member being opened in a ganged relation with a shutter which is opened when the built-in camera type video tape recorder is loaded on the connecting apparatus, and a terminal portion facing an opening portion of the shutter member and the supporting member and being electrically connected to a signal input and output portion projected from the opening portion opened when a shutter of the connecting apparatus is opened.

Abstract: A video camera apparatus including a video camera device, a battery for supplying electric energy to the video camera device, an adapter detachably mounted in the video camera device to connect the video camera device with the battery, and a connecting device. The video camera device may be attached to the base unit and thereby be connected with another electrical apparatus, such as a VCR.

Abstract: An adapter pack is constructed so that it can be connected to a video camera via the site via which the battery pack is normally connected. The adapter pack is itself provided with a mounting site on which the battery pack can be connected. This construction allows the adapter pack to be operatively "sandwiched" between the battery pack and the camera. The adapter pack is arranged to permit the power from the battery pack to be supplied both to its own circuitry and therethrough to the camera.
