Abstract

PURPOSE:To enable only a specific person to input the data by moving a pointed position on a display screen in accordance with the moving direction and distance of a finger detected by a finger movement detection means. CONSTITUTION:An optical scanner 21 which detects a fingerprint pattern serves as a cursor shift operation means to a display device 26. Then the moving direction and distance of a finger are obtained based on the pattern detection data given from the scanner 21, and the cursor shift control data is obtained. Thus the scanner 21 can detect the fingerprint pattern at any position and any angle and does not need a sufficient shift space for a mouse. Thus the cursor shift is controlled with high accuracy. Furthermore the coincidence/ discordance is decided between the registered fingerprint patterns of users and the fingerprint pattern of an operator. Thus the security is ensured for an input access.
