  • Patent number: 4017837
    Abstract: A data recording system by means of which data can be typed on a form and subsequently automatically punched into the same or a different form. A typewriter is coupled to a memory so that as data is typed onto the form the data is captured in the memory. After the typing of the form has been completed, the same form or a different form is inserted into a card punch which is also coupled to the memory, and the same data is punched into that form. When the same form is typed and punched the form is usable both as a business document readable by people and as an input document to a data processing system.
