Data Input Device

The apparatus reads record cards and stores the card data in a core matrix storage device.

Record cards 10 are sensed row by row by brushes 11 and circuit
12. The data from each row is first stored in a row buffer 13 and then read out to a translator 14 by word ring 15 and digit ring 16. Translator 14 translates the readout pulses into coded representations of the row.

A shift register 17 receives ten digits of information from the translator and shifts these digits, in parallel, into storage unit 18. An emitter 19 controls one coordinate of the core storage unit 18 to provide for common storage locations 18A for data from card rows 12, 11 and 0; 18B for data from card rows 1, 2, 3 and 4; and 18C for data from card rows 5, 6, 7, 8 and 9. Since each storage location 18A, 18B and 18C contains a plurality of row positions, each word of data in storage unit 18 must be accumulated from successive rows of data from a card 10. The emitter 19 also controls the readout of recorded rows of data from storage unit 19 to shift register 17.
