When a fixed time elapses, a timer 11 actuates to operate a rotation driving source 8' which in turn rotates the shield plate 10' in the same direction at the same speed as that of the shield plate 10 so as to assure even exposure time, thereby cutting off the radiated light as shown in (c). The shield plte 10' then stops by slightly overlapping the shield palte 10. The rotation driving sources 8, 8' are rotated in the direction opposite from before to return the shield plates 10, 10' to the normal state.

Abstract: PURPOSE:To accomplish an accurate ghost cancellation signal, by giving a pilot pulse signal formed immediatly before the ghost detecting section to a delay circuit, and storing the signal at a tap of the delay line with a pilot pulse signal detected from the signal at a tap of the post stage. CONSTITUTION:A vertical synchronizing signal from a synchronizing separation circuit 16 is applied to a pilot pulse generating circuit 51 to obtain the pilot pulse at the leading edge of the vertical synchronizing signal. This pulse is applied to an adder 52 and superimposed on a ghost detecting signal. This signal is given to a demultiplexer 12 to obtain the pilot pulse at the tap of the final stage. This signal is applied to a pilot pulse detection circuit 53 and a gate pulse is produced at a gate pulse generating circuit 38. At this time point, a ghost detection signal distributed on each tap of the demultiplexer 12 is stored in capacitors 181-18n. Thus, even if the delay characteristic of the demultiplexer 12 is changed, the change in ghost cancelling time point is avoided.

Abstract: PURPOSE: To secure elimination of the DC fluctuation caused by the saturation voltage between the collector and the emitter of the transistor by giving the conduction in other half-cycle of the rectangular wave to the transistors which are in the complementary relation.  
     CONSTITUTION: PNP transistor Tr17 is turned on in the half cycle period of rectangular wave 10 applied to input terminal 1, and capacitor C8 is charged up to power voltage +E as shown by arrow 20. Thus, the value of voltage E 3  is obtained. This value shows the amount added with the effect caused by the leak voltage between the emitter and the collector of Tr17. Then Tr17 is turned off in the other half cycle with PNPTr4 turned on, and accordingly the electric charge in C8 is discharged as shown by arrow 21 to obtain voltage E 2 . In this case, it is supposed that Tr17 and 4 feature the identical ambient temperatures. As a result, the saturation voltage between the collector and the emitter is substantially identical between Tr17 and 4 thus to obtain E 2 =E 3 , and accordingly the DC-changed output level never change with every half cycle of the rectangular wave.

A DC voltage is applied to the base of the  TR15 with a DC power supply 16 and the drain voltage of the FET3 is kept to a voltage almost equal to the voltage value of the power supply 16. Since the collector of the  TR15 is connected to a negative power supply -B via a resistor 17, even if the resistance value of the resistor 17 due to the limitation of the amplification factor and the  like, the DC potential at an output terminal 8 can be set to an arbitrary voltage value  depending on the setting of the current of the current source 9 or the voltage of the  power supply -B. When a positive signal is applied to an input terminal 1, the current  of the FET3 is increased, and the current of the TR15 is decreased in terms of the increment and the level at the terminal 8 goes toward the negative polarity.
