Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
A data transmission system for an endoscope apparatus which performs data-transmission between at least two of an endoscope, a photographic attachment and a light source unit, comprising: a first data transmission/reception device provided in the light source unit and including at least one data generating means and at least one means responding to a reception data; a second data transmission/reception device provided in at least one of the endoscope and the photographic attachment; two-way data transmission lines provided in the endoscope to relay data between the first and second data transmission/reception devices; and means for connecting the data transmission/reception devices and the two-way data transmission lines.
Claim 2
Dependent Claim
106 words
A data transmission system for an endoscope apparatus which performs data-transmission between at least two of an endoscope, a photographic attachment and a light source unit, comprising: a first data transmission/reception device provided in the light source unit and including at least one data generating means and at least one means responding to a reception data; a second data transmission/reception device provided in at least one of the endoscope and the photographic attachment; two-way data transmission lines provided in the endoscope to relay data between the first and second data transmission/reception devices; and means for connecting the data transmission/reception devices and the two-way data transmission lines.
Claim 3
Dependent Claim
37 words
A data transmission system according to claim 1, wherein the first data transmission/reception device is connected to the two-way data transmission lines of the endoscope by coupling a connector of the endoscope to the light source unit.
Claim 4
Dependent Claim
29 words
A data transmission system according to claim 1 or 2, wherein the second data transmission/reception device is provided in the endoscope and connected to the two-way data transmission lines.
Claim 5
Dependent Claim
39 words
A data transmission system according to claim 1 or 2, wherein the second data transmission/reception device is provided in the photographic attachment and is connected in the two-way data transmission lines by mounting the photographic attachment on the endoscope.
Claim 6
Dependent Claim
36 words
A data transmission system according to claim 1 or 2, wherein each of the endoscope and the photographic attachment is provided with a second data transmission/reception device which is connected to the two-way data transmission lines.
Claim 7
Dependent Claim
91 words
A data transmission system for an endoscope apparatus according to claim 1 wherein said data transmission/reception device provided in said photographic attachment includes an input port connected to release switch, a film type detector for detecting a film type code, an exposure calculator for calculating an exposure amount of a film, a counter for counting frames of the film, and a shutter-full-open detector for detecting a full-open of the shutter, and an output port connected to an auto-exposure display and a display for displaying the number of frames of the film.
Claim 8
Dependent Claim
50 words
A data transmission system for an endoscope apparatus according to claim 1 or 6 wherein said data transmission/reception device of said endoscope includes an output port connected to an air-feed control valve action indicating means, a suction valve action indicating means, and a display for displaying at least measured values.
Claim 9
Dependent Claim
92 words
A data transmission system for an endoscope apparatus according to claim 1 wherein said data transmission/reception device provided in said endoscope includes an input port connected to an air-feed switch, a water-feed switch, a suction switch, a feed-gas changing switch, and a filter insertion switch, an input port connected to a temperature measuring circuit, a pH measuring circuit, air-pressure measuring circuit, and a body-pressure measuring circuit; and an input port connected to an observation light quantity adjusting signal generator, an air-feed quantity adjusting signal generator and a feed-water pressure adjusting signal generator.
Claim 10
Dependent Claim
51 words
A data transmission system for an endoscope apparatus according to claim 1 wherein said data transmission/reception device of said light source unit includes an input port connected to an air valve action detector, a suction valve action detector, a charging-over detector, an automatic exposure detector, and an optical path switching-over detector.
Claim 11
Dependent Claim
57 words
A data transmission system for an endoscope apparatus according to claim 1 or 9 wherein said data transmission/reception device of said light source unit includes an output port connected to an electronic flash, a filter driving circuit, an air-feed valve device, a water-feed valve device, a suction valve device, an observation light source circuit and a display.
