To allow a controlled object to perform two or more mutually related functions (operations) by seamless (a series of) operations of a user.

A detection part arranged in an input device outputs signals corresponding to distances L1, L2 from an indication body 41 to the detection surface of the detection part. A control part arranged in the input device detects the distances L1, L2 from the indication body 41 to the detection surface, based on the output of the detection part, and allows a controlled object to perform a first function and, subsequently, a second function related to the first function in accordance with the distances L1, L2.
