An objective that is a concave lens and an ocular that is a convex lens are arranged in a finder housing with a predetermined space between them. The finder housing is molded of a black plastic material. A diaphragm portion is integrally formed inside an inner peripheral portion of the finder housing and between the objective and the ocular. The diaphragm portion is formed to be as large as a lens portion of the ocular. The diaphragm portion serves to block unwanted reflected light.

Finder housing

Pawls are formed on an outer peripheral portion of an operation dial at intervals equal to step rotating angles of the operation dial so that a user's finger nail can be placed on one of the pawls to rotate the dial. When the finger nail is placed on one of the pawls to rotate the operation dial, the finger nail placed on that pawl abuts against a stopper provided on a camera main body. Thus, rotation of the operation dial is stopped at each step rotating angle.

Electronic equipment and camera

When a wheel is rotated, first inclined portions of end surface cams provided on the wheel push corresponding cam followers formed on a movable cylinder. Accordingly, the movable cylinder holding a photographing lens is extended. Then, when each of the cam followers reaches a first flat portion of the corresponding end surface cam, the movable cylinder is placed in a photographing position. In the photographing position, when the wheel is further rotated, the cam follower is pushed by a second inclined portion of the end surface cam. The movable cylinder is thus extended. Then, when the cam follower reaches a second flat portion of the corresponding end surface cam, the movable cylinder is placed in a macro photographing position.
