Abstract

A touch operation information output apparatus is provided in a position at which a driver can operate it, and detects a touched position with respect to the input pad and outputs its coordinate data to the display device. Here, protruding brackets are provided at 16 positions on the input pad. A first group of protruding brackets that are in 4 positions at a center of the input pad are formed in a "+" shape, a second group of protruding brackets that are in four corners of the input pad are formed in an "L" shape and a third group of protruding brackets are formed in a "T" shape. Because of this, the driver can recognize the touched position with respect to the touch operation information output apparatus and blind operation becomes possible.
