1,207,335. Card readers. TATEISI ELECTRONICS CO. 28 Sept., 1967 [4 Oct., 1966], No. 10014/60. Divided out of 1,207,334. Heading G4M. Data read from a card, similar to that disclosed in the parent Specification but not having a direction distinguishing mark b, is stored in the same order irrespective of the orientation of the card on insertion for comparison with a stored code. One or other of a pair of bi-stable circuits (6a, 6b) is set depending on the direction of insertion, and the outputs of these circuits either enable one of 2 groups of counter controlled gates (12) or control the direction of counting. |
