  • This invention relates to record controlled tabulating machines, and particularly to mechanism adapted to print the perforated data of successively sensed, diiTerent areas of the same card, at a plurality of places on a record sheet.
  • a ninety column data card is used, which is divided into upper and lower Zones.
  • Each Zone has forty-tive columns of six data index positions per column, or 270 code hole index positions.
  • the sensing means consequently, requires 540 sensing pins and a like number of set pins for registering, in a single sensing operation, the perforated data possible in the two zones of a single card. It has been found desirable to print on the same line of a record sheet or business form, duplications of data perforated but once in either an upper or lower zone of the card.
  • a further object is to use the same wires in a connection box to transmit data from either zone of the card, and to group said wires in such manner relatively to the six index position per column area at which the sensed data is concentrated, that the total number of wires required is materially reduced, can be readily secured in place, and can be replaced or changed as desired with a minimum of effort and time.
  • Another object of the invention is to provide sensing pin locking means, so that different areas of a card can be sensed in successive machine cycles to print data from one area of the card at different places on one line of a record or business form, and from another area of the same card at different places on another line of said form.
  • Another object is'to arrange the group of wires in the connection box so that printing of data from one area of the card may be done at two places on one line of the form, and from another area of the same card may be done at one place ⁇ on another line of the form.
  • additional objects of the invention contemplate the printing of the total at a plurality of locations on the same line of a business form; the control oi total taking mechanism for intra-card totaling by the use of designation data fields; the progressive sensing of the rones or zonal elds of a single card by the control of mechanism whose action is initiated by one or more perforations in said card and the printing of a business form in two, three, or four subsequently detachable parts, with information duplicated in each part and taken from different iields of one or more cards.
