Description: A key punch is discussed which would be useful in any automatic coding system requiring the initial input to be made via cards with 12 rows such as the standard IBM card. The proposed key punch consists of a keyboard connected to a punch and a electric typewriter so that if a character is struck, it is both punched in a single card column and typed on a sheet of paper. Each character key contains three characters which may be used in superscript, subscript, or main line position. (M.H.R.)
