Abstract
Abstract A video camera operating device which permits the photographing lens of the camera to be controlled either in an automatic mode or a manual mode from a remote operating device. Both the remote operating device and a close operating device on the video camera body include an automatic focusing/manual focusing changeover switch. When the remote operating device is connected to the video camera via a cable, the automatic focusing/manual focusing changeover switch of the remote operating device takes precedence over that of the close operating device. The remote operating device also includes controls for selecting short or long distance movement of the lens and for controlling the speed at which the lens is moved.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
88 words
A video camera operating device including a close operating device and a remote operating device, comprising: means for causing an operating mode selected by an automatic focusing/manual focusing changeover switch of said remote operating device to take precedence over an operating mode selected by an automatic focusing/manual focusing changeover switch of said close operating device; and driving means for remotely driving a video lens when said automatic focusing/manual focusing switch of said remote operating device is operated at least for a manual focusing mode in a remote operation.
Claim 2
Dependent Claim
88 words
A video camera operating device including a close operating device and a remote operating device, comprising: means for causing an operating mode selected by an automatic focusing/manual focusing changeover switch of said remote operating device to take precedence over an operating mode selected by an automatic focusing/manual focusing changeover switch of said close operating device; and driving means for remotely driving a video lens when said automatic focusing/manual focusing switch of said remote operating device is operated at least for a manual focusing mode in a remote operation.
Claim 3
Dependent Claim
30 words
The video camera operating device as claimed in claim 1, wherein a voltage for driving a focusing motor can be set to a desired value by said remote operating device.
Claim 4
Dependent Claim
127 words
A video camera operating device comprising: a close operating device and a remote operating device, said close operating device being positioned within a body of said video camera, and said remote operating device being coupled to said body of said video camera via a cable, each of said close operating device and said remote operating device having an automatic focusing/manual focusing changeover switch, and said close operating device comprising means for controlling a focusing position of a photographing lens of said camera in response to said automatic focusing/manual focusing changeover switches of said close operating device and said remote operating device with said automatic focusing/manual focusing changeover switch of said remote operating device having precedence over said automatic focusing/manual focusing changeover switch of said close operating device.
Claim 5
Dependent Claim
127 words
A video camera operating device comprising: a close operating device and a remote operating device, said close operating device being positioned within a body of said video camera, and said remote operating device being coupled to said body of said video camera via a cable, each of said close operating device and said remote operating device having an automatic focusing/manual focusing changeover switch, and said close operating device comprising means for controlling a focusing position of a photographing lens of said camera in response to said automatic focusing/manual focusing changeover switches of said close operating device and said remote operating device with said automatic focusing/manual focusing changeover switch of said remote operating device having precedence over said automatic focusing/manual focusing changeover switch of said close operating device.
Claim 6
Dependent Claim
50 words
The video camera operating device as claimed in claim 3, further comprising connector means for connecting said cable to said close operating device, said connector means comprising switch means for detecting when said cable is connected, an output of said switch means being applied to said focusing position controlling means.
Claim 7
Dependent Claim
66 words
The video camera operating device as claimed in claim 4, wherein said remote operating device further comprises a remote power focus switch and first and second contacts to which said armature is selectively set for selecting between long-distance and short-distance movement of said photographing lens, said remote power focus switch being connected via said cable to said focusing position controlling means of said close operating device.
Claim 8
Dependent Claim
83 words
The video camera operating device of claim 5, wherein said remote operating device further comprises variable resistor means for selecting a speed of movement of said photographing lens during a focusing operation, said variable resistor means being coupled via said cable to said focusing position controlling means of said close operating device, and said close operating device comprising means for controlling a speed of movement of said photographing lens during a focusing operation in response to an output of said variable resistor means.
