Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 118 words
An endoscopic photographing apparatus comprising: an endoscope having an eyepiece section; a camera mounted on the eyepiece section of the endoscope; a light supply unit for emitting light for illuminating a foreground subject through said endoscope; a medical electronic device connected to said endoscope for generating a high frequency current causing consequential noise components during operation of same for medical purposes; means for detecting the start of a photographing operation period of said camera to produce an output; and and means for stopping the generation of output of the high frequency current of said medical electronic device at least for the period of the photographing operation in response to the detection of the start of the photographing operation.
Claim 2
Dependent Claim 118 words
An endoscopic photographing apparatus comprising: an endoscope having an eyepiece section; a camera mounted on the eyepiece section of the endoscope; a light supply unit for emitting light for illuminating a foreground subject through said endoscope; a medical electronic device connected to said endoscope for generating a high frequency current causing consequential noise components during operation of same for medical purposes; means for detecting the start of a photographing operation period of said camera to produce an output; and and means for stopping the generation of output of the high frequency current of said medical electronic device at least for the period of the photographing operation in response to the detection of the start of the photographing operation.
Claim 3
Dependent Claim 38 words
The endoscopic photographing apparatus according to claim 1, wherein said output generation stopping means includes a timer for holding said medical electronic device inoperative for said photographing operation period in response to the output of said detecting means.
Claim 4
Dependent Claim 109 words
The endoscopic photographing apparatus according to claim 1, wherein said camera includes an automatic exposure calculating circuit for generating a release signal in response to a release operation and generating an exposure terminal signal when a proper exposure is obtained, said detecting means including an electronic circuit set in response to said release signal and reset in response to said exposure signal, and said stopping means including means for stopping the operation of said medical electronic device in response to a set signal of said electronic circuit and causing the resumption of the operation of said medical electronic device in response to a reset signal of said electronic circuit.
Claim 5
Dependent Claim 28 words
The endoscopic photographing apparatus according to any of claims 1, 2 or 3, wherein said detecting means and output stopping means are provided in said medical electronic device.
Claim 6
Dependent Claim 22 words
The endoscopic photographing apparatus according to any of claims 1, 2 or 3, wherein said medical electronic device is an electrosurgical device.
Claim 7
Dependent Claim 41 words
The endoscopic photographing apparatus according to any of claims 1, 2 or 3, wherein said detecting means and output stopping means are assembled in an adapter, said adapter being mounted between a connector of the endoscope and the light supply unit.
