Abstract

1388597 Magnetic card reader-writer system ING C OLIVETTI & C SpA 19 April 1972 [22 April 1971] 59393/72 Divided out of 1388593 Heading G4M A magnetic card reader-writer for computer program cards has two side plates 201 carrying two parallel card guide plates 202, 203 a magnetic head 207 mounted on one side plate and a belt co-operating with a pressure wheel to transport a card through the reader. The side plates are arranged so that the edges of the card contact their inner surfaces. The guide plates are recessed to receive the rollers and the head. The reader-writer contains a card sensor comprising a switch 206, an arm 291 pivoted at 262 and a sensing portion pivoted at 290. One arm 292 of the sensing portion is pivoted when a card is sensed. When the card passes under another arm 293 the arm 291 is pivoted to operate the switch.
