覆い隠すので作業がしにくいといっだ問題があった。However, in this case, in order to guide the lens 1 through the guide plate 3, the lens 1 must protrude from the disc 2 by at least the thickness of the guide plate 3, and the lens 1 must be inserted into the hole 3a of the guide plate 3. When inserting the lens, the plate surface may come into contact with the lens end surface and damage the lens end surface. When the lens 1 enters the hole 3a of the guide plate 30, the edge of the lens 1 may be chipped. When fixing the receptacle body to the receptacle body with adhesive, the guide plate 3 covers a large part of the disc 2, as shown in FIG. 4, making it difficult to perform the work.
