Abstract
A handwritten-image input apparatus comprises a pen, a controller, a display device, and a tablet. The tablet detects the position of the pen thereon. The display device displays a trace made by the pen on the tablet, under the control of the controller. The pen includes a switch for detecting whether or not the pressure applied to the pen exceeds a predetermined value. When the switch is ON (when the pressure applied to the pen is greater than the predetermined value), the controller controls the display device to increase the line width of the trace, made by the pen, which is displayed on the display device. When the switch is OFF (when the pressure applied to the pen is less than the predetermined value), the controller controls the display device to decrease the line width of the trace, made by the pen, which is displayed on the display device. When the width of the displayed trace made by the pen reaches a predetermined value, the controller does not increase the line width any further.
