RUGGEDNESS DETECTING SENSOR, RUGGEDNESS DETECTING DEVICE, FINGERPRINT RECOGNITION DEVICE, AND INDIVIDUAL DISCRIMINATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a ruggedness detecting sensor having a high S/N. SOLUTION: Detecting elements 10 each composed of a detecting electrode 1 and a conversion circuit 2 which converts the capacitance formed between an object near the electrode 1 and the electrode 1 into a voltage or current are arranged in an array of N vertical columns and M horizontal rows. The detecting elements 10 are connected to scanning lines 100 laid along the columns of the array and output lines 200 laid along the rows of the array.
