<p>A system comprises a digitizer which includes a position indicator and a coordinate detecting device in the form of a tablet and has a selection/indication area within its coordinate detecting surface to select/indicate data processing functions, a display device, and a computer which controls the digitizer and the display device, wherein the data processing functions are selected/indicated by using the position indicator to perform an image processing. In the system, the coordinate detecting device comprises an indication part which is located within the selection/indication area of the coordinate detecting surface of the coordinate detecting device and makes it possible the status of selections/indications of the data processing functions to be visually observed. The indication part comprises an engaging means which temporarily engages with the position indicator (7) and is movable together with the engaged position indicator, an indicator means (35, 36, 37), which is movable with the engaging means which is temorarily engaged with the position indicator (7), to visually indicate a selected/indicated data processing function, and a supporting means (32, 33, 34) to engage and support the indicator means. <IMAGE></p> |
