<p>PURPOSE:To use a mouse even if a private program for mouse is not executed by means of software by substituting a moving quantity data and mouse button data, which can be obtained by means of using the mouse for the key code of a keyboard. CONSTITUTION:When the mouse is moved from a point P1 to a point P4 by setting a point P0 as an origin, a direction key code output circuit 5 outputs direction key code data 11 of plural moving key codes in the direction of an (x) axis '+ x' or '- x' and moving key codes in the direction of a (y) axis '+ y' or '- y' to an OR circuit 9. When a mouse button detection circuit 7 detects the depression and the release of a mouse button, mouse button data 12 is generated, and is transmitted to a mouse button key code output circuit 8. The mouse button key code output circuit 8 reads the key code corresponding to mouse button data 12 from a mouse button code storage part 6 and it is outputted to the OR circuit 9 as mouse button key code data 13.</p> |
