Abstract

858,605. Sensing record cards. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 14, 1958 [April 12, 1957], No. 11732/58. Class 106 (1). A sensing device for punched record cards has pins 6 for each hole position of the card urged upwardly by blade springs 8, each of which co-operate with a contact 9 when the associated pin passes through a hole in the card to complete an electrical circuit and to limit the projection of the pin. The pins are normally held withdrawn by a member 10 to allow the card to pass into position between a block 2 and guide plate 1. When the card is in position the member 10 is raised to allow sensing to take place, the stroke of the sensing pins being adjustable by moving the contacts 9. A plurality of sensing pins may be arranged in staggered pairs. The pin 6 and contact spring 8 may be a single L-shaped piece.
