Abstract

This counter employing an objective lens counts thin flat substantially white articles while they remain in a carton. Cards 1 (see A) packed side by side in opened carton 2 are moved by belt 3 past at least one scan unit 4 at station 5. Unit 4 includes (see B) high intensity light source 6 to illuminate the card edges and adjustable objective lens 7 that is accurately focused to magnify successive card edges and project their images to photocell or phototransistor 8 via adjustable aperture plate 9. A pulse is emitted when 8 senses the dark spaces between adjacent cards. Where valuable items like credit cards are to be counted, count is verified by providing another unit 4 focused on the same or a different edge. In such case both sets of pulses, as amplified, go to respective registers 10,11.

Counter for Packaged Flat Articles

This counter employing an objective lens counts thin flat substantially white articles while they remain in a carton. Cards 1 (see A) packed side by side in opened carton 2 are moved by belt 3 past at least one scan unit 4 at station 5. Unit 4 includes (see B) high intensity light source 6 to illuminate the card edges and adjustable objective lens 7 that is accurately focused to magnify successive card edges and project their images to photocell or phototransistor 8 via adjustable aperture plate 9. A pulse is emitted when 8 senses the dark spaces between adjacent cards. Where valuable items like credit cards are to be counted, count is verified by providing another unit 4 focused on the same or a different edge. In such case both sets of pulses, as amplified, go to respective registers 10,11. If counts agree, total may be entered in accumulator 12 by pressing button E, which also clears out 10,11. If counts disagree, reject button R is pressed to clear totals from 10,11 and not enter any count in 12; then cards are recounted.

If 4 and 10,11 use synchronized timing systems, belt 3 is driven at constant speed. Masks 13 of L-shaped metal painted white are inserted into each end of the carton to control pick-up response and start and stop the counting cycle for each carton and prevent the end of the carton from being improperly counted as a card.

This counter, employing an objective lens, is especially useful for objects like credit...
