ている。In FIG. 2, reference numeral 20 indicates a movable reflective mirror of the camera according to the present invention, and a portion of the mirror 21 is made of ABS synthetic resin.
The support shaft 22, 22' and the drive pin 23 are integrally molded.

れる。Acrylic synthetic resin may be used as the base material of the mirror, and after molding a part of the mirror, one coat of chemical nickel plating is applied to the entire surface, and then 100 g of electrolytic steel plating is applied on top of that, followed by mirror cutting under the processing conditions described above. The mirror surface is coated with chrome to prevent the electric field between the copper plating and the reflective film A.
A reflecting mirror with a reflectance of 90% or more can be obtained by vapor-depositing s, and then vapor-depositing an AfL reflective film and a reflection-enhancing film thereon as described above.

。(Effects of the Invention) As described above, the present invention integrally molds the mirror and the support shaft from synthetic resin, so the reflective mirror can be attached to a camera mirror box, etc., without using a receiving plate as shown in the conventional example. It can be directly attached, eliminating the need for processing and assembling and adjusting many parts as in the past, making it extremely inexpensive to manufacture.As the mirror is extremely lightweight, the driving force for the mirror is also small, making it easy to use when shooting. The time required for the mirror to stabilize is also short, which is advantageous during continuous shooting.
