Abstract

PURPOSE: To obtain a chart reading device which can correct the reading error caused by the lens aberration or the like via the electronic means.
CONSTITUTION: With installation of reference counter 1 to scan the chart on the paper, gate circuit 2, image sensor 3 and data counter 4, the start pulse is applied to sensor 3 via circuit 2 and at the same time both counter 1 and 4 start counting. Data selector 5, since it performs selection by the output of counter 1, can fractionate the range of the chart on the paper. And the data of the fractionated range can be corrected by turning on switch 6 corresponding to the fractionated range of the chart on the paper. Correction circuit 7 is used to decide previously whether +1 or -1 is given to the contents of counter 4, and counter 4 features the same counting as counter 1 and also can perform +1 or -1 via circuit 7.
