Abstract

PURPOSE:To obtain agreeable cool feeling like natural wind in such a way that the signal part of a signal is read out by means of optical sensors, and a fan motor is controlled for ON and OFF according to the read-out program signals. CONSTITUTION:Signal paths 7, 8, 9 for slight current, light current, and strong current are indicated by means of printing, etc., and signal parts 10, 11, 12 for changing air flow volume are programmed on each signal path respectively changing phases in the circumferential direction. Since beam from light emitting diodes 14, 15, 16 passes to light receiving diodes 17, 18, 19 on each signal part 10, 11, 12, and the light receiving diodes 17, 18, 19 are turned ON by detecting the beam, the signal parts 10, 11, 12 on the signal plate 6 can be read out gradually optically with its turning, so that each air flow volume notch for the slight current, light current, and strong current can be started.
