A keyboard control apparatus for a keyboard having a multicode key, to which are assigned a plurality of codes for characters and symbols, and a control key which is to be pressed at approximately the same time as the multicode key, has a key pressing time delay detection means that detects the times of pressing the multicode key and the control key, a threshold setting means, into which is stored a threshold value with regard to the delay time, a comparison means which compares the threshold value to the delay time between the pressing of the multicode key and the control key, and a key code generation means which, in response to the results of this comparison, validate a prescribed code data of the multicode key in the case in which the delay time is smaller than the threshold value.
