Clock (timing) scale or clock (timing) disc

摘要

The invention relates to a clock scale or a clock disc for the exact positioning of working machines, handling devices or other actuators, comprising a transparent material on which encodings for sampling via optical sensors are arranged, the transparent material (1) being provided on that side remote from the transmitter (6) with a reflecting layer (8). The invention furthermore relates to a method for producing a clock scale or a clock disc, in which the transparent material, comprising a film with a photosensitive layer (9), is exposed via masks or a photoplotter with encodings and subsequently developed, a metallic coating is undertaken on the photosensitive layer (9) and the clock discs and clock scales are separated individually from the exposed and coated film material. <IMAGE>
