Abstract
PURPOSE: To aviod the read-in disable due to card inversion, by turning over the data read in up and down and making conversion as the read in data, when the detection signal from the detection means to detect the position of corner cut of a card is inverted.
CONSTITUTION: The position of the card 50 is detected with the corner cut position detection set 10 feeding the output to the decoder conversion circuit 22 connected to the read station 21 reading in the information of the punched card 50. The photo cells 3, 4 and 5 of the position detection set 10 detect the position of the corner cut of the card 50. The output of the photo cells 3, 4, and 5 is fed to the logical sub gates 6 and 8 to detect the inversion of up and down left and right, and the result of detection is fed to the data conversion circuit 22 and the buffer control section 24 via the latch gates 7 and 9. Further, if the output of the down inversion detection signal line 11 and the feft and right inversion detection signal line 12 is inverted, the data is read in with the inversion of the data conversion circuit 22 to enable to the read in the data when the card is inverted.
