Abstract

Data transmission/reception devices are provided in endoscope, photographic attachment and light source unit. The data transmission/reception devices are connected with one another by two-way data transmission lines.

Claims

1. 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.]. .Iadd.line means .Iaddend.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.]. .Iadd.line means.Iaddend..

2. A data transmission system according to claim 1, wherein the first data transmission/reception device is connected to the two-way data transmission .[.lines.]. .Iadd.line means .Iaddend.of the endoscope by coupling a connector of the endoscope to the light source unit.

3. 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.]. .Iadd.line means.Iaddend..

4. 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.]. .Iadd.line means .Iaddend.by mounting the photographic attachment on the endoscope.

5. 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.]. .Iadd.line means.Iaddend..

6. 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.

7. 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.
