Abstract
Abstract An adapter for coupling a camera adapted to receive electric power from an endoscope to which the camera is coupled, to an endoscope having no function of electric power transmission. The adapter is coupled between the ocular section of the endoscope and the mounting of the taking lens of the camera and has electric power output terminals for providing the camera with electric power. The adapter can have a built-in power source or a plug-in power source.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
An adapter for coupling a camera having electrical control circuits with an endoscope having an ocular section, said camera being of the type having camera control circuits adapted to receive electric power through an endoscope to which the camera is coupled, and said endoscope having no function of electric power-transmission to a camera which is coupled thereto, said adapter comprising: first means for detachably coupling the adapter to the endoscope at the ocular section of the endoscope; second means for detachably coupling the adapter to the camera; and electric power output terminals disposed in said second means for electrically connecting the control circuits of said camera to an electric power source separate from said endoscope, whereby said camera control circuits can receive electric power.
Claim 2
Dependent Claim
124 words
An adapter for coupling a camera having electrical control circuits with an endoscope having an ocular section, said camera being of the type having camera control circuits adapted to receive electric power through an endoscope to which the camera is coupled, and said endoscope having no function of electric power-transmission to a camera which is coupled thereto, said adapter comprising: first means for detachably coupling the adapter to the endoscope at the ocular section of the endoscope; second means for detachably coupling the adapter to the camera; and electric power output terminals disposed in said second means for electrically connecting the control circuits of said camera to an electric power source separate from said endoscope, whereby said camera control circuits can receive electric power.
Claim 3
Dependent Claim
17 words
An adapter as defined in claim 1, wherein said adapter further comprises a built-in electrical power source.
Claim 4
Dependent Claim
32 words
An adapter as defined in claim 1, wherein said adapter further comprises electric power input terminals by which said electric power output terminals can be connected to a plug-in electrical power source.
Claim 5
Dependent Claim
35 words
An adapter as defined in claim 3, wherein said adapter further comprises a changeover switch by which said electrical power output terminals are selectively connected to either of said built-in or plug-in electric power sources.
Claim 6
Dependent Claim
25 words
An adapter as defined in claim 1, and an optical compensation system in the adapter between the ocular section of the endoscope and the camera.
