<p>PURPOSE:To easily input such position information that moves a point moving in accordance with a traveling object in parallel to an axis X or Y by providing a switch between the 1st/2nd detectors and an information processor to cut off the 1st and 2nd signals separately from each other. CONSTITUTION:A switch 23 is provided between the 1st/2nd detectors 21/22 and an information processor to cut off the 1st and 2nd signals separately from each other. That is, when the 1st or 2nd signal is cut off by the switch 23, one of both signals is outputted to the information processor. Therefore a straight line parallel to the axis X, for example, can be drawn on the display of the information processor. At the same time, a straight line parallel to the axis Y can also be drawn. Thus, the position information so as to move the point moving in accordance with the traveling object in parallel to the axis X or Y is easily inputted on the display.</p> |
