Televison camera and remote-controllable video signal recording/reproducing apparatus
First Claim
1. A television camera for producing an output electrical signal indicative of images of a subject, the camera comprising:
- (a) a body;
(b) a lens system attached to said body;
(c) a photosensitive element held in said body and being responsive to light rays from said lens system for producing a video signal;
(d) a camera cable for transmitting the output signal of said television camera, said camera cable having a plurality of wires;
(e) first means for holding a wireless remote-control unit so that said remote-control unit is detachably attached to said body, the remote control unit being of a type that emits light rays as output signals;
(f) second means for receiving the output signals from said remote-control unit, said second means including a photosensitive device responsive to the light rays emitted from said wireless remote-control unit; and
(g) third means for transmitting said output signals received by said second means to said camera cable so that said output signals of said remote-control unit can be fed via some of said wires of said camera cable to an associated device.

Abstract
A remote-control unit for producing operating mode-control signals of a video signal recording/reproducing apparatus is detachably attached to the body of a television camera. The output signals of the remote-control unit are fed via wires included in the camera body to some wires of a television camera cable which is connected to the recording/reproducing apparatus when using the camera. The output signals of the remote-control unit may be applied via its cable or via conductors attached to the housing of the unit to the camera. A wireless remote-control unit arranged to emit light rays may be attached to the camera body so that the light rays are received by a photosensitive element provided to the camera. In order that the remote-control unit may be used together with and independently of the camera, the pins of a remote-control unit cable jack of the recording/reproducing apparatus are connected to some pins of a camera cable jack of the apparatus. A remote-control device may be built in the camera body when detachability is unnecessary.

2. A video tape recording/reproducing system comprising:
-
(a) a television camera for producing an output electrical signal indicative of images of a subject, the camera including; a body; a lens system attached to said body; a photosensitive element held in said body and being responsive to light rays from said lens system for producing a video signal; a camera cable for transmitting the output signal of said television camera, said camera cable having a plurality of wires; first means for holding a remote-control unit so that said remote-control unit is detachably attached to said body; second means for receiving remote-control signals from said remote-control unit; and third means for transmitting said remote-control signals received by said second means to said camera cable; and (b) a video tape recording/reproducing apparatus, including; fourth means for driving a recording medium; fifth means for processing an input signal to record the same on said recording medium; sixth means for receiving signals from said television camera via said camera cable, said sixth means having a plurality of conductors respectively contactable with said wires of said camera cable, some of said conductors being connected to said fifth means for feeding said fifth means with the output video signal from said television camera; seventh means for receiving signals from said remote-control unit which has been detached from said television camera, said seventh means having a plurality of conductors connected to said fourth means for controlling the operation of said video signal recording/reproducing apparatus in response to remote-control signals from said remote control unit; and eighth means having a plurality of conductors connected between said conductors of said seventh means and some of said conductors of said sixth means so that remote-control signals fed via said television camera cable are fed to said fourth means when said remote-control unit is attached to said television camera. - View Dependent Claims (3, 4)
