<p>873,857. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 18, 1958 [Dec. 24, 1957], No. 40892/58. Class 100(4) Record controlled wire printers. An interpreter comprises a sensing station 12 for reading information on a first medium, e.g. record cards, a translator 39 and a printing mechanism for producing representations of the data sensed on an intermediate medium, e.g. a tape 41, feeding means to bring the record cards and the tape together at a card printing station 55 where the representations are transferred from the tape 41 to the record card. As shown the sensing station 12 comprises twelve 'brushes 21 on sliding rods 22 mounted on a carriage 23 slidable on a guide rail 24 and reciprocated so the brushes 21 move transversely across all columns on the card. The carriage is driven in either direction by a rack 25 according to whether a left or rightward clutch 26, 27 is engaged. Coupled for similar movement is a wire printing head which, through a conventional ink ribbon forms characters on the tape 41; the particular character formed is determined by movements of a code rod, set up from the translator 39. A control emitter 30 comprising sliding contact 33 and connections to a series of plugs, determines which group of columns on the card is read. After the tape 41 is printed it is advanced into a loop 124 and the first card advanced to a relay station 54 and a second card is read at sens'ng station 12 and the data therein is printed in the tape 41. In the next printing cycle when a third card is at the sensing station the first card is advanced to the printing station 55 and the first representations are fed from the loop 124 to a position above this first card. The first card together with the tape 41 is now rolled through pressure and heat transfer rolls 92, 94 transferring the printed information from the tape to the card. Line-spacing. The printing may be effected' on any line on the card by vertical or downward movement of tape feed rollers 64, 65 secured on shafts 85, 86 axially slidable in the hubs of driving gears 87, 88. This movement is controlled by a twelve-position pluggable control emitter 79 and effected by operation of an " up" " or " down " clutch driving a rack 69 attached to a yoke 68 fixed to the shafts 85, 86. Reversible arrangements. In every alternate line the brushes 21 sense in reverse direction and accordingly the representations are formed from right to left in that section of the tape 41 by the printing mechanism 40. Web feeding. The tape 41 is perforated at one edge only. Specification 729,064 is referred to.</p> |
