A method for preparing NC (numerical control) tapes for use with numerical control machine tools wherein the information required for preparing the NC tapes is divided into three types of information, one type being machine item information, one being tool item information, and the third being drawing information, with the three types being fed into an information processing unit, the first type information being taped, the second type information being either taped or carded, both types of information being adapted for use by the operator so that such information can be selected when needed from a storage area for use and reuse in the information processing unit, the third type of information being adapted for feeding directly into the information processing unit by reason of a movable index operation of an input table and push button operation of function keys mounted on keyboard, by an operator's manual operation thereof based on his discretion.
