Abstract

PURPOSE:To generate a signal quantity exceeding three times that of a conventional article by the number of signals per one rotation, in case of an optical rotary encoder having the same outside diameter by realizing a high division of a slit plate by using that which has manufactured a rotary slit plate and a fixed slit plate by an electroforming method. CONSTITUTION:A resist mask treatment shown in 7 is executed on a metallic substrate 8, and an exposure and a development are executed. Thereafter, in order that an electroforming part and the substrate are peeled off easily, it is immersed in a dichromate solution, and thereafter, electroforming is executed. When a slit plate 3 grown by nickel electroforming is peeled off from the substrate, a slit plate which is scarcely deformed, sharp and has high accuracy is obtained. In case of this working, photoengraving of only a grown portion of plating is corrected. As for the quality of material of the slit plate 3, not only nickel but also various metals can be used, but a hard metal is desirable in order to make a thickness of the slit plate small. Also, a photosensitive resin or a photodetecting ink, etc. can be used instead of a resist 7. Also, as for the slit plate, a rotary slit and a fixed slit can be worked at the same time by the same method.
