を検知する光学的読みとりセンサとしては、各種のもの
が提案され、実施されている。Various types of optical reading sensors have been proposed and implemented in the past, which detect information signals by receiving reflected beams from media on which information is optically recorded by a light-receiving element via a lens. .

へ取付けられている。By the way, the above-mentioned optical reading sensor uses various lenses, but the objective lens is particularly important in terms of input and output of the light beam, and the objective lens is carefully designed to prevent optical axis misalignment with the sensor body. It is attached to the support with great care.

しまうという欠点があった。By the way, as a conventional method of supporting an objective lens,
A common method is to inject adhesive between the objective lens and the support, allow the adhesive to harden, and then fix the objective lens to the support. The drawback is that it is not easy to do. In addition, the objective lens is cut to form a flat part on the side of the objective lens, and this flat part is fixed in contact with the flat part of the support to achieve positional accuracy between the support and the objective lens. However, this method has the disadvantage that secondary reflection of the light beam occurs at the cut flat part of the objective lens, and the detected image becomes blurred.
