Abstract
A voltage-controller is used for controlling a CCD (charge couple device) image sensor including an n-type semiconductor substrate and a p-type semiconductor layer formed on a main surface thereof. Charges stored in the layer are swept therefrom to the substrate in accordance with a differential potential therebetween. The voltage-controller comprises a pulse signal controlling circuit, for outputting driver signals to transfer signal charges from the image sensor, and for outputting a pulse voltage to the substrate. A power source is provided for supplying positive and negative voltages to the pulse signal controlling circuit through a first power line and a second power line to control the outputs thereof. A discharging circuit is provided in the second power line to selectively ground the same upon termination of the output of the negative voltage supplied from the power source.
