Abstract

The card punch has a program drum based on tabulator set-clear principles that replaces or supplements the conventional program drum using a punched card. At A, card punch 1 has key entry unit 2 and feeds cards for punching from hopper 3 to stacker 4 via bed 5. A program drum assembly is housed at 6. Unit 2 has control switches 7 with a master field control switch 8 added, shown in detail at B, and a modified keyboard 9 at C for setting, clearing and controlling a tabulator-program drum assembly 13 shown at D and E. Switch 8 has clear momentary, off, and set positions. Keyboard 9 includes spacebar 10, numeric X key 11, and alphanumeric Y key 12. Drum assembly 13 has 80 tabulator stops 14 mounted for up-down movement in individual channels.

Switch 8 has clear momentary, off, and set positions. Keyboard 9 includes spacebar 10, numeric X key 11, and alphanumeric Y key 12. Drum assembly 13 has 80 tabulator stops 14 mounted for up-down movement in individual channels. They are settable to home position, lowest, by yoke 15 when switch 8 is moved to clear position. Drum 13 is incremented to set individual stops to the numeric X or alphanumeric Y position by appropriate reciprocal movement of interposer 16. Sensors 17 and 18 are operated by stops 14 during rotation of drum 13 to direct the apparatus to accept alphabetic data, accept numeric data, skip to the next field set tab stop.
