Abstract
PURPOSE:To detect present positions of respective coaters with high precision by distinguishing direction of movement of the coaters by the order of outputs of two pulse signals having phase difference output from respective optical signal detection systems and counting pulse number of one hand and calculating the moving distance of the coaters. CONSTITUTION:Both a rotary encoder 11 in which directions of movement and moving distance of respective coaters 4R, 4C, 4L are subjected to pulse signalization and measured with a pulse scale rotated to the normal and reverse directions according to movement thereof and a controlling device 18 which outputs a controlling signal for controlling the intervals between the coaters while matching them with the previously programmed coating width of a material to be coated on the basis of the measured value of the encoder 11 are provided. This encoder 11 consists of both a pair of optical signal detection systems 13A, 13B which are opposed to the code pattern of the above- mentioned pulse scale and provided along the direction of rotating and a reversible counter 14 which counts the pulse signals of two phases having constant phase difference output from respective optical signal detection systems and detects the present positions of coaters.
