<p>PURPOSE:To clearly recognize the position of a cursor and the point indicated by a cursor by using a rotary indication input means and an input position confirming symbol rotation means. CONSTITUTION:The intersecting point between two straight lines orthogonal to each other is shown in white on a black background for a graphic cursor 401 and the position of said white point is defined as an input position. In such a way, the apex of a line pattern 302 can be confirmed and indicated at the upper side of the pattern. However it is inconvenient to indicate the apex at the middle part of the pattern. In order to solve such inconvenience, a CPU can recognize the ON/OFF information on a switch 501 via a mouse interface like conventional switches 502 and 503.</p> |
