It is connected to the timing pulse input terminals (T (T2) (T5) (T4) through the basso fan circuit (Bu)...in addition, as the photosensitive element IAI that constitutes the above sensor group). A visible light full spectrum amorphous optical sensor, AM-31[]1 manufactured by Sanyo Electric Co., Ltd. was used, and a silicon diode was used as the diode ID+.

ので入力容量０１として０．２、μＦを付加した。Since the operational amplifier (OP) inputs a signal to its child terminal, it operates as a non-inverting amplifier circuit. The area around this operational amplifier is partially shown in @5N, and according to this circuit configuration, the input and output (vi, VO) have the same polarity (Vi and vO are in phase) and the gain of one circuit (vO/v1 ) is (1+ Rf
/R,), and has the advantage that the input impedance can be very high. In addition, the load resistance R1 of the photosensitive element is set to 47 Ω from the illuminance-output voltage characteristic, and when a fluorescent lamp is used as a light source, a ripple appears in the input (vl), so the input capacitance 01 is set to 0.2 μF.
