1. A remote control transmitter, comprising:
- a wiring board where electronic components for generating a remote control signal are mounted;
a housing for installing the wiring board;
an operating unit disposed at an upper face of the housing, an arbitrary portion of an outer part of the operating unit can be moved in a depressed direction;
a resistor unit having a changing amount of resistance according to a position along a and a conductor unit both provided under the operating unit, said resistor unit and said conductor unit opposed to each other with a space therebetween, said resistor unit and said conductor unit contactable with each other at said position along said path;
a controlling part for measuring a voltage output by the conductor unit depending upon said position where said resistor unit and said conductor unit are contacted; and
a transmitting part for transmitting one of a plurality of remote control signals in response to said voltage.

Abstract
A substantially ring shaped resistor unit and an conductor unit with a certain space therebetween are provided under an operating unit having a substantially disc shape or a substantially ring shape. When an operating unit is depressed, the resistor unit and the conductor unit are contacted with each other at a position at which the depression is provided. Based on the contact, a controlling part detects the position at which the depression is provided, and a transmitting part transmits a remote control signal corresponding to the position at which the depression is provided.
