ABSTRACT:
An object of the present invention is to provide a coordinates input apparatus whereby various operations on a screen can be carried out where practicable with one finger, and the number of operations reduced, thus giving a marked improvement in user operability. The coordinates input apparatus of the invention therefore comprises a detection section and an operating section. The detection section is provided with an operating surface for operation by a coordinates pointer such as a finger, and detects the operating conditions on the operating surface caused by the coordinates pointer. The operating section executes screen operations corresponding to the operating condition detected by the detection section, and in addition detects tapping of the coordinates pointer on the operating surface within a predetermined region, and carries out previously determined processing.
