摘要 |
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.
