发明名称 DISTANCE MEASURING APPARATUS
摘要 PROBLEM TO BE SOLVED: To improve an enclosure structure, for a distance measuring apparatus, in which a pair of light guide gaps in a diaphragm part can be filled with a transparent filler uniformly up to every corner without leaving the unfilled part of the transparent filler without lowering the performance of the distance measuring apparatus. SOLUTION: In the distance measuring apparatus, an optical lens part 1 equipped with a pair of distance measuring lenses 1R, 1L, the diaphragm part 2 in which the light guide gaps 2a corresponding individually to the lenses and incident-light diaphragm holes 2R, 2L are formed inside a trunk and a sensor stage 3 which houses a semiconductor photosensor chip 5 used to measure a distance up to a subject from a subject image to be image-formed through the distance measuring lenses are piled up and coupled, their inside gap is filled with the transparent filler 6, and the sensor chip is sealed. A continuity flow channel 2c to be used as a communication passage when the pair of light guide gaps are made to communicate in order to fill the transparent filler is formed in the diaphragm part, and a light blocking wall is installed inside the continuity flow channel.
