Abstract
A device for reading from and writing on, magnetic cards for use in a desk-top computer having a cover with an introduction slot and an exit slot for the cards. The device comprises two parallel guides between the introduction and exit slots for defining the path to be traversed by the cards, two support plates for the guides disposed perpendicular thereto for guiding the lateral edges of the cards and a belt cooperating with pressure rollers to entrain the card as it passes through the guides. The device also includes a microswitch and a shoe which has two projections contacting the non-magnetizable face of the card, the shoe being hinged on a lever actuating the microswitch when the card has passed below the projections.
