| description | PROBLEM TO BE SOLVED: To provide a coating apparatus which has a coating means for applying a liquid or pasty coating material on the surface of a substrate moving relatively to one direction and can cope even with an unexpected fluctuation by preventing an influence due to disturbance factors. SOLUTION: This apparatus is provided with one or more state quantity detecting means for detecting the state quantity interrelated to the state of a coating bead, one or more state quantity changing means for changing the prescribed state quantity correspondingly to the prescribed controlled variable and a calculation part. In order to maintain the state of the coating bead so as to obtain the coating quality as reference, the state quantity of the coating bead is controlled by repeating in real time a series of processings consisting of the detection processing that the state quantity detecting means detects the state quantity, the arithmetic processing that the calculation part calculates the controlled variable corresponded to the state quantity obtained by the detection processing and the state quantity changing processing that the state quantity changing means changes the state quantity according to the controlled variable obtained by the arithmetic processing, in this order.
