PROBLEM TO BE SOLVED: To solve the problem wherein complicated operation is needed for a remote controller having multiple signal transmitters, since a changeover switch should be manipulated whenever the operation changes between the one at the controller carried by hand and the one at the controller placed on a desk. SOLUTION: A control unit comprises a control unit having buttons pressed down by a user, a signal generator for receiving a button information associated with a pressed down button and generating corresponding a corresponding button code signal, multiple signal transmitters for transmitting the button code signal, and a transmission switch for switching between two signal transmitters for signal transmission, according to a chassis angle.
