Abstract

This reader uses document cards 20 such as the 80-column type. The reader comprises hopper 22, aligning station 24, read station 26 and stacker 28, and a card 20 is fed serially out of hopper 22 and in continuous motion through stations 24 and 26 into stacker 28. Since card 20 is not stopped for alignment purposes and is not fed transversely into a corner station, the card transport is very simple, low cost and compact.

Document Card Reader

This reader uses document cards 20 such as the 80-column type. The reader comprises hopper 22, aligning station 24, read station 26 and stacker 28, and a card 20 is fed serially out of hopper 22 and in continuous motion through stations 24 and 26 into stacker 28. Since card 20 is not stopped for alignment purposes and is not fed transversely into a corner station, the card transport is very simple, low cost and compact.

Aluminum plate 30 provides a backbone to which all drive and transport components attached. The machine drive consists of a motor 32 which face mounts to plate 30, and a timing belt 34 used to transmit power to a jack shaft 36 and first read roll shaft 38. jack shaft 36 in turn drives hopper pick belt 40 and 0- ring belt 42 that drives cupped aligner rolls 44 and 46, which are made of rubber- like material.

Cards 20 to be fed through the transport are placed vertically in hopper 22 in the form of a card deck. Hopper 22 includes a forward plate or shroud 48 and a pressure tray 50 moveable under pressure from a spring, for example, toward shroud 48 for holding the deck of cards against shroud 48. Tray 50 is provided with a pressure spring 52 on its lower end, which forces an end card 20 of the deck into alignment with the gap between a throat block 54 and a throat knife 56.

Belt 40 passes around a pick roll 58 mounted on a bell crank 60 and moveable through an opening in shroud 48 into contact with the end card 20 of the deck within hopper 22. A magnet 62 swings crank 60 and thereby swings pick roll 58, so that belt 40 drives the endmost card 20 of the deck downwardly between throat block 54 and throat knife 56. As a card 20 is thus picked, it passes across throat knife 56, and it is driven downwardly by pick belt 40.

Card 20 passes between throat roll 64 and pressure roll 66 and between card guides 68 and 70 which guide card 20 around a radius. Read station drive roll 72 is driven from shaft 38 and has a pressure roll 74 cooperating with it. Rolls 72 and 74 are placed approximately a card length plus one inch from throat roll 64, and this allows card 20 to be under control of the two cupped aligner rolls 44 and 46 which are placed between throat roll 64 and rolls 72 and 74 along the card transport.

Cupped aligner rolls 44 and 46 are mounted on shafts which rotate in bearings that are mounted in the lower card guide 70, and rolls 44 and 46 are continuously running under...
