Abstract

A coordinate inputting apparatus capable of being used in combination with a device generating noise, comprises an input section for inputting coordinates, a detecting section for detecting the input coordinates, and a control section for controlling the entire coordinate inputting apparatus. The control section sets a detecting time during which the detecting section detects the coordinates and a non-detecting time during which detection is not performed, the detecting time and the non-detecting time being alternately repeated, and the control section controls the coordinate inputting apparatus so that an operation of the device is stopped for at least a time during which the coordinate inputting apparatus is otherwise affected by the noise, the time being part of the detecting time.

the control section further controls the coordinate inputting apparatus so that when the operation of the device is resumed, at least part of a delay time of rising of the device is included within the time during which the coordinate inputting apparatus is otherwise affected by the noise.

5. A coordinate inputting apparatus according to claim 4, wherein the length of the delay time of the rising is equal to the length of the time during which the coordinate inputting apparatus is otherwise affected by the noise.
