Abstract

Data from manually inserted punched badge 10 and card 1 1 and from manual setup station 12 are optically sensed by a moving carriage 14 coacting with read head 18. Reversible motor 24 reciprocates 14, connected to timing belt 25, so that mirrors 15...17 move past 10...12 serially. Stationary source of collimated light 20 illuminates mask 21 having a vertical slit. The vertical light pattern passing through the slit reflects off right-angle, stationary mirror 22 and is directed to movable mirror 15. The latter passes the beam to partial mirror 16. This reflects a portion of the light to photocell 26 and passes the remainder to the surfaces of the data input members, illuminating them column-by-column as 14 moves to the right. Light passed by data holes is transmitted by 17 to the input of 18.

Reversible motor 24 reciprocates 14, connected to timing belt 25, so that mirrors 15...17 move past 10...12 serially. Stationary source of collimated light 20 illuminates mask 21 having a vertical slit. The vertical light pattern passing through the slit reflects off right-angle, stationary mirror 22 and is directed to movable mirror 15. The latter passes the beam to partial mirror 16. This reflects a portion of the light to photocell 26 and passes the remainder to the surfaces of the data input members, illuminating them column-by-column as 14 moves to the right. Light passed by data holes is transmitted by 17 to the input of
18.

Assembly 18 comprises a plurality of light pipes 27, one for each data row of members 10...12, arranged to transmit light to a photocell contained in rotating scanning cylinder 28. The latter scans the bits of each column serially and transmits data output signals to the stationary half of pot-core transformer 33. The remaining details of 18 are described in the IBM Technical Disclosure Bulletin, Volume 7, No. 6, November 1964, at pages 476-477. A stationary, multiapertured strip 23 is positioned between 15 and 16 to chop the scanning beam to provide an optical input to 18 only during the time when the beam is passing a d...
