Abstract
Disclosed is an input apparatus including a coplanar line formed on the surface of a substrate so as to pass through the vicinity of a position at which a user performs an operation, terminating resistor placed at one end of the coplanar line and a microcomputer module at the other end. The microcomputer module has a signal transmitter for outputting a signal to the coplanar line. When the user operates a key, the impedance of the coplanar line changes and a reflected wave is produced. A signal detector in the microcomputer module detects the reflected wave and outputs received-signal strength information, which indicates the strength of the signal included in the reflected wave, to a computing unit. Based upon the received-signal strength information and strength of the signal that has been output by the signal transmitter, the computing unit in the microcomputer module discriminates the key that has been operated and specifies the entered instruction.
