1. A portable information terminal apparatus comprising:
- display means for displaying information;
a sensor module including an array of a plurality of sensors which detect user operation;
display control means for controlling information displayed by the display means in accordance with a result detected by the sensor; and
sensor control means for controlling operation of the sensors by controlling supply of power to the sensors and when there is a sensor which has detected an input from a user, continuing supply of power to the sensor and neighboring sensors and stopping supply of power to the remaining sensors.

Abstract
A touch sensor detects contact input by a finger or the like, and includes two sensor modules. Each of the sensor modules has many sensors arrayed linearly. The operation state of each sensor module is set under the control of a control unit. When a user touches a sensor of the sensor module, the control unit energizes only the sensor which the user has touched and neighboring sensors to detect an input from the user, and does not energize the remaining sensors on the same sensor module.
