The instruction mark is at instruction position 5,
A second indicated position away from the indicated position is also shown. The pointer stick 2 has a function selection section 4, and when the function selection section is operated with the pointing position 5 indicated, the function selected by the function selection detection system 23 is executed by the control device 24. At this time, by setting the display target to be executed not to the pointing position 5 hidden under the pointing stick 2 but to the second pointing position of the pointing mark 11, easy-to-use screen input can be obtained. At the indicated position 5 or the second indicated position, the display contents are updated,
It may be a function of changing the displayed content, such as erasing, or a function of transmitting a signal from the control device 24 to another system connected to the display device. At this time, as long as the area of the indicated position detected by the coordinate detection system 21 is wider than the display screen, the second indicated position can be displayed in any part of the display area.

Next, the relationship between the pointer stick 2, the pointer position 5, and the pointer mark 11 will be explained in detail with reference to FIG. Display area 1
At the top, a pointing position 5 is indicated by a pointing rod tip 6. Then, an instruction mark 11 is displayed. The indication mark 11 indicates at least the indication position 5 and the second indication position 20 which is distant from the indication position. In order to move the second pointing position while fixing the pointing position 5, the rotation 9 in the axial direction of the pointing stick, the angle 8 between the display surface and the pointing stick, and the azimuth 7 of the pointing stick 2 within the display surface are adjusted. The indicator mark may be moved, rotated 10, or deformed by providing a detection means and detecting changes in these angles. Similarly, the instruction mark may be moved or transformed by operating the function selection section. Furthermore, the tip of the indicator rod 6
may be transparent to make it easier to see the second indicated position.
