Abstract
When coordinate data are entered from a tablet with a pen, the pen is operated on the tablet while depressing a predetermined key of a keyboard. A signal generated by the depression of the predetermined key is supplied to a keyboard controller. Upon reception of the signal, the keyboard controller stops sending key code data entered from the keyboard to an input/output controller. In this manner, undesirable data entry due to the improper operation of the keyboard is prevented when coordinate data are entered with the pen.
