Abstract

PURPOSE: To eliminate the pre-scanning signal appeared at the joints between blocks, by adding the switch in parallel with the load resistor added to each block of the photo electric conversion element and by obtaining the output through opening the switch only at scanning.
CONSTITUTION: The load resistors VR1, VR2... are added to the output terminal of each block constituted in 16-bit, and after picking up the photo electric conversion signal of each block with the scanning pulse determining the signal pick up period, logical sum is taken. The scanning pulse is sequentially fed to the analog switches SW1, SW2..., and at non-scanning, the pre-scanning signal appeared at the joints between blocks can be rejected by selecting the signal pick up side of block to the level not causing the photo electric conversion signal.
