Abstract

A video endoscope system includes an endoscope having in its imaging system a solid state imaging device for generating a video signal of an image of an object to be observed or examined which in turn is transmitted through a control circuit to a CRT display to be visualized thereon as a television picture and to a video tape recorder. A manually operable control switch on a hand-held control section of the endoscope actuates the video tape recorder to start recording the transmitted video signal on a video tape when desired. The provision of the control switch operable remotely from the video recorder permits an endoscope operator to start the video recorder when desired, without calling on others observing the television picture to perform the recording operation, which avoids the risk of delays and faulty communications that might otherwise result.

Claims

1. A video endoscope system comprising:

an endoscope having a hand-held operating section and a viewing head in which a solid state imaging device is provided for generating video signals associated with an image of an object observed by the endoscope;

positioning means disposed on said hand-held operating section for aligning said viewing head in any desired viewing direction;

video display means for visibly displaying the image of the object;

recording means for recording said video signals on a video signal recording medium, said recording means being remote from said hand-held operating section;

copy producing means for producing a hard copy of the image of the object;

a control circuit through which said video signals are transmitted to said video display means, recording means and copy producing means; and

first means on said hand-held operating section for selectively enablng and disabling at least said recording means.

2. A video endoscope system as defined in claim 1, wherein said first means comprises two manually operable push buttons for actuating said recording means and copy producing means, respectively.

3. A video endoscope system as defined in claim 1, and manually operable actuating means on said recording means and copy producing means.

4. A video endoscope system as defined in claim 1, wherein said first means is a manually operable push button provided on the hand-held operating section.

5. A video endoscope system as defined in claim 4, wherein said manually operable push button operates to enable said recording means while said push button is depressed, and to disable said recording means when said push button is released.
