PROBLEM TO BE SOLVED: To recycle an objective lens and an ocular for a finder by attaching a plate-like member which is transparent and formed so that its front and back surfaces may be parallel at least to any one of aperture parts for incident and emitted light of the objective lens and the ocular for the finder. ;SOLUTION: The 1st plate-like member 17 formed of transparent resin material such as polyethylene terephthalate(PET) so that its front and back surfaces may be parallel is attached to a groove formed in the aperture part for incident light 15a for making subject light incident on the objective lens 13 on a front cover 15. Similarly, the 2nd plate-like member 18 formed of the transparent resin material such as PET so that its front and back surfaces may be parallel is attached to the groove formed in the aperture part for emitted light 16a for emitting the subject light from the ocular 14 to a pupil on a rear cover 16. Then, the objective lens 13 and the ocular 14 are respectively coated and protected by the 1st and the 2nd plate-like members 17 and 18. Therefore, a figerprint, a scratch or the like is not left on the objective lens 13 and the ocular 14.;COPYRIGHT: (C)1999,JPO
