ことを特徴とするプリント基板保持機構。 In the printed circuit board holding mechanism, which inserts the printed circuit board into the printed circuit board mounting housing according to the guide tool and fixes the printed circuit board to the housing, a cylindrical elastic body with a through hole and a concave groove that can hold the printed circuit board is used. a circular plate A having a hole and a concave groove formed on its outer surface; a circular plate B having a screw hole and a concave groove formed on its outer surface; and screwing the elastic body through the hole in plate A and fixing it to plate B. A fixing device consisting of a bolt that can be inserted is placed on both sides of the printed circuit board, and the printed circuit board with the fixing device attached is placed in a housing formed by opposing grooves with a circular cross section into which the fixing device can be inserted. By inserting the elastic body into the groove and tightening the bolt, the distance between plates A and B is reduced, and as a result, the outer diameter of the elastic body is expanded so that it can be fixed to the housing by closely contacting the inner wall of the groove with a circular cross section. A printed circuit board holding mechanism characterized in that by loosening a bolt, the outer diameter of an elastic body becomes multiplied and the printed circuit board can be removed from a groove having a circular cross section.
