Wiring trench parts 12, 22 are formed in the same direction as a rotary shaft, so as to intersect the respective three channel trenches on the respective facing surfaces of the rotary core 1 and the fixed core 2. The channel windings 13, 23 are led out from any one of the wiring trenches of the respective cores, and, for example, the channel winding 13 wound around the rotary core 1 is connected with the respective six rotary heads. By this constitution, channel windings 13a, 13d in a wiring trench 12a are sufficiently separated, so that signals scarcely generate crosstalk. The wiring trench 12 can be one-half of the number of channels, so that the facing area of the fixed core 1 and the rotary core 2 is large, electromagnetic coupling is superior, and signal transmission efficiency is improved.

The switch SW8 is turned on, an integrating circuit which is composed of an operational amplifier 561 is reset. After that, the switches SW7, SW8 are turned off. The switch SW6 is turned on. Then, a voltage which is input via a resistance R6 is integrated. After its integratting operation is started, a prescribed time elapses. Then, the switch SW6 is turned off, and the switch SW7 is turned off. Then, an electric charge which is charged in a capacitor C is discharged via an electric discharge circuit 563. A detection signal at an electric discharge timing and that at a completion timing are output from an amplifier 562. The signals are input to the control part 57, and the electric discharge time is measured by using a timer 574.  The electric discharge time is proportional to a quantity of light which is received by a light receiving element 51. When the electric discharge time is converted into a quantity of received light per unit time, an illuminance can be calculated.
