PURPOSE:To perform an effective input of information by operating manually a keyboard and operating a pedal with a foot. CONSTITUTION:A keyboard 2 which feeds manually information and a pedal 3 which feeds information by means of a foot are provided to a terminal device 1. Thus the constitution and operation of a keyboard can be simplified compared with a conventional case where the information is supplied through the keyboard 2 only. At the same time, the load can be reduced for the operating fingers.
