Abstract: 1,104,771. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. 25 Jan., 1966 [15 Feb., 1965], No. 3241/66. Heading G4M. Cards are fed from a primary hopper 20 and a secondary hopper 21 along separate paths past a reading station 22 which is capable of reading a card in either path, and into a proceasing path which includes a punching station 23 and a printing station 24. Photo-cells 37-45 are spaced along the card paths to detect the positions of cards in the machine, and cam-operated switches are associated with the drive shafts of the feed mechanism, punching station 23 and printing station 24, these photo-cells and switches operating in conjunction with a programme control circuit 26 to synchronize the sequence of card processing operations specified in the programme with the passage of cards through the machine. The control circuit 26 may comprise a read-only memory. Photo-cells 37-39 co-operate with primary or secondary feed instructions to control the feeding of cards from hopper 20 to primary input station A and thence to primary pre-read station C or from hopper 21 to secondary preread station B. In response to a read primary or read secondary instruction, a common pressure roller between the primary and secondary paths is actuated by a magnet to feed the primary or secondary card through photo-electric reading station 22. As the trailing edge of the card uncovers photo-cell 38 or 39, a timing track is recorded on emitter 58 attached to the shaft of feed-roll 31, so as to provide gating pulses as successive columns of the card are read. When the card leaves the pinch of roller 31, switches on the feed cam-shaft, in conjunction with the primary or secondary feed instruction, energize a magnet (61) or (62), Fig. 3 (not shown), to actuate a common pressure roller for roller 63 or 64 to feed the card at low speed into a position where a pusher can engage the trailing edge of the card and thereby register the card in punch station 23. If punching is to take place, clutch 70 is energized to drive camshaft 71 for one revolution, and in response to a punch primary or punch secondary instruction, a magnet (72 or 73) is energized to allow the appropriate pusher to follow a cam follower 74 to register the card. Punch drive 91 is incremental for punching the card column-bycolumn. At the end of punching, or if punching is not to occur, a common pressure roller is actuated so that roller 32 or 33 ejects the card from punching station 23. When the card reaches cell 43, a magnet (76), Fig. 6 (not shown), is energized to lower a gate (77) into the card path and stop the card in proper registration with the printing station 24. Lateral alignment of the card is effected by a magnet which is energized when cell 42 is covered by the card entering the printing station, the magnet moving the card against a side guide member. The gate is then raised and eject roller 35 is engaged if printing is not specified, or incremental drive 81, 82 is engaged if printing is to take place. Cell 45 controls the operation of a magnet to charge the direction of card travel toward stackers 25, one or other of which may be specified by circuit 26. If no stacker is specified, primary and secondary cards go to stackers 1 and 5 respectively.
