Title: Photometric circuit provided with latch unlocking circuit
Inventor: YONEDA OSAMU
IPC: G01J1/44
Filed: 1981-09-18
Abstract: PURPOSE:To simply release charge accumulation generated in a photodiode by making neutral current flow into a connecting point between the photodiode and a diode for logarithmic convertion for a prescribed period. CONSTITUTION:A photometric circuit is provided with a latch unlocking circuit. By closing an electric power switch SW1, for example, positive charge on the cathode side of a photodiode PD is discharged as the charging current for a capacitor C1 through a diode D3, a resistor R2 and a diode D1. Consequently the diode D3 is biased by the difference between the charging voltage of the capacitor C1 and the reference voltage of an operational amplifier A2. The charge of the photodiode PD is discharged by the diode D3. Thus, latch unlocking operation kept stably up to low illumination can be obtained.
