Abstract

Abstract A portable endoscope having a control part containing an entrance end portion of a light guide for transmitting light for illuminating an object, and a hermetic illuminating light supply unit containing a light source lamp for supplying illuminating light to the light guide. The unit is connected to the control part. An armoring member is disposed at a position where it is heated by heat radiated from the light source lamp. The outer surface of the armoring member is covered with a heat-insulating cover made of a material having a low thermal conductivity. A battery chamber is formed in the illuminating light supply unit to accommodate a battery as a power supply for the lamp. A relief valve releases the pressure in the battery chamber to the outside of the unit when the pressure rises.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 162 words
A portable endoscope having a control part and an illuminating light supply unit, in which the control part has an entrance end portion of a light guide that transmits light to illuminate an object, the illuminating light supply unit containing a light source lamp that supplies illuminating light to the light guide, the illuminating light supply unit being connected to the control part said portable endoscope comprising: an armoring member disposed at a position where it is heated by heat radiated from a light source lamp of said portable endoscope; and a heat-insulating cover that covers an outer surface of said armoring member, said heat-insulating cover being made of a material having a low thermal conductivity, an illuminating light supply unit of said portable endoscope being detachable with respect to a control part of said portable endoscope, wherein said armoring member comprises a cylindrical member that projects from said control part to connect said illuminating light supply unit to said control part.
Claim 2
Dependent Claim 162 words
A portable endoscope having a control part and an illuminating light supply unit, in which the control part has an entrance end portion of a light guide that transmits light to illuminate an object, the illuminating light supply unit containing a light source lamp that supplies illuminating light to the light guide, the illuminating light supply unit being connected to the control part said portable endoscope comprising: an armoring member disposed at a position where it is heated by heat radiated from a light source lamp of said portable endoscope; and a heat-insulating cover that covers an outer surface of said armoring member, said heat-insulating cover being made of a material having a low thermal conductivity, an illuminating light supply unit of said portable endoscope being detachable with respect to a control part of said portable endoscope, wherein said armoring member comprises a cylindrical member that projects from said control part to connect said illuminating light supply unit to said control part.
Claim 3
Dependent Claim 24 words
A portable endoscope according to claim 1, wherein said heat-insulating cover has a cylindrical configuration for covering an outer surface of said armoring member.
Claim 4
Dependent Claim 158 words
A portable endoscope having a control part and an illuminating light supply unit, in which the control part has an entrance end portion of a light guide that transmits light to illuminate an object, the illuminating light supply unit containing a light source lamp that supplies illuminating light to the light guide, the illuminating light supply unit being connected to the control part, said portable endoscope comprising: an armoring member disposed at a position where it is heated by heat radiated from a light source lamp of said portable endoscope; and a heat-insulating cover that covers an outer surface of said armoring member, said heat-insulating cover being made of a material having a low thermal conductivity, an illuminating light supply unit of said portable endoscope being detachable with respect to a control part of said portable endoscope, wherein said armoring member transfers heat to a metallic member which forms an outer wall of said illuminating light supply unit.
Claim 5
Dependent Claim 158 words
A portable endoscope having a control part and an illuminating light supply unit, in which the control part has an entrance end portion of a light guide that transmits light to illuminate an object, the illuminating light supply unit containing a light source lamp that supplies illuminating light to the light guide, the illuminating light supply unit being connected to the control part, said portable endoscope comprising: an armoring member disposed at a position where it is heated by heat radiated from a light source lamp of said portable endoscope; and a heat-insulating cover that covers an outer surface of said armoring member, said heat-insulating cover being made of a material having a low thermal conductivity, an illuminating light supply unit of said portable endoscope being detachable with respect to a control part of said portable endoscope, wherein said armoring member transfers heat to a metallic member which forms an outer wall of said illuminating light supply unit.
