摘要：<p>PURPOSE:To always read accurately information out of a data card by regulating a foul slope or position shift of the data card to an information detector after detecting them. CONSTITUTION:A reading head 9 contains a train 4 of information detectors arrayed in the direction vertical to the feed direction A of a data card 1. Then position shift detectors 5/8 and 6/7 are set on the diagonal lines respectively to hold the train 4 between them. The head 8 can move toward arrow heads B and B' along a guide 13, and a rectangular shift detecting circuit which produces the drive signal of a drive motor 10 is provided with adders 22 and 23, a subtractor 28 and an amplifier 28. The drive signals are supplied to drive motors 14 and 15 via an adder 29, an amplifier 32, an adder 30 and an amplifier 33. Thus the card 1 is sent toward A. Adders 20 and 21, a subtractor 24, a non-reverse amplifier 26 and a reverse amplifier 27 are provided to a feed angle detecting circuit which produces control signals of motors 14 and 15.</p>
