Abstract
977,010. Selective punching. O. C. SELDEN. Nov. 28, 1963, No. 47029/63. Heading B4B. A punching device for punching information on a record carrier, such as a tape or card, comprises at least one punch which is operationally connected with a control switch to be operated when the punch has perforated the record carrier, the control switch being arranged in an electric circuit to indicate the operation of the switch. As shown, a record carrier 4 passed between a base-plate 2 and a matrix 3 is punched by a transverse row of punches 1, each of which when actuated by a member 7 to perforate the carrier depresses a spring 5 so that the free end of the spring makes contact with a fixed contact 8 to close an electric circuit and provide an indication that a hole has been punched. Each circuit may contain an additional switch which is closed when the information that a hole has been punched is fed into the device, the switch and control switch operating a relay to stop the device when the control switch has not closed. The switches and relays may be replaced by transistors. An additional hole position may be provided which is punched each time the information is represented either by an even number of holes or an odd number of holes, the control circuits associated with the punches being so combined that the operation of the punching device is stopped when the total number of holes in a transverse row is not an odd number or is not an even number respectively.
