Abstract
PURPOSE:To fit a fitting member directly in contact with the substrate of an encoder plate by providing a protective film which protects the code pattern of the encoder plate outside the fitting area for the encoder plate. CONSTITUTION:The protective film 24 which protects the encoder pattern is adhered to the surface of an encoder disk 21, i.e. the formation surface side for the encoder pattern 22 the protective film 24 is adhered to the part except the peripheral edge surface of the center hole 21a of the encoder disk 21, i.e. fitting area 21b. Consequently, the surface of the disk substrate is exposed in the fitting area 21b of the encoder disk 21 and the fitting member 26 fitted on a shaft 25 such as the arm of a motor robot is fitted directly in contact with the disk substrate surface.
