Card Reader

The device reads and validates a single marked or punched card. No card weight being needed, a card can be dropped in the reader which readily adapts it for use in reading job cards or order cards.

A card, dropped in hopper 10, is drawn flat onto perforated bed plate 11 by vacuum chamber 12. The suction is sufficient to hold the card flat but not prevent it being fed. Cam driven picker knife 14 feeds a card into the bite of feed rolls 15 and 16. These carry the card into guides 17, which in turn guide it past a sensing station 18, a printing station 20 to feed rolls 21 and 22 and stacker 23. The feed rolls and stacker are continuously driven. The picker knife drive is under control of two switches 24 that are closed by the card when in feed position. The print wheel 30 is controlled by a numbering device, not shown.

At the sensing station 18, light from lamp 25 is reflected from a card to activate a photo-cell 26 indicating the presence or absence of a mark. Suitable circuits, not shown, store signals from the sensing device to control other devices such as punches, printers, etc. The switches 24 also control a circuit that indicates a card presence at print position 20. It is timed to control the firing of a hammer 27 to print characters on the card through ribbon 28 by means of print wheel 30.

After printing, the card is fed by rolls 21 and 22 to a stepped vibrating plate 31 in the stacker. This plate is oscillated by a cam 32 to jog a card down to...
