<p>PURPOSE:To decrease the wrong key input operations by enabling an operator to set the position of a pointing device like a finger, etc., approximately at the center of a desired key based on an image of a magnified keyboard shape. CONSTITUTION:When a touch-on state is obtained while a keyboard-shaped image is displayed on a display device 4, a touch panel control part 6 informs a control part 9 of the touched-on coordinates. The part 9 gives the magnification control data centering on the informed coordinates to a screen magnification control part 8 for display of a magnified screen. Thus an operator can set a pointing device like a finger, etc., approximately at the center of a desired key. Then the operator changes the touch position approximately at the center of a desired key based on the keyboard-shaped image displayed with magnification and then performs a touch-off operation. Thus the part 6 informs the part 9 of the relevant coordinates. The part 9 decides an input key based on the coordinates and inputs the decided key. Thus it is possible to decrease wrong key input operations.</p> |
