Abstract
Abstract The remote control device is equipped with at least one movable panel arranged rotatably to cover an operation panel having a plural number of operation keys arranged thereon, so composed as to permit manipulating the operation keys from an upper side of the movable panel and having function markings imprinted thereon, and is composed in such a manner that, when the operation panel is covered with the movable panel, a remote control transmitter is switched to the function mode displayed on the movable panel and transmits, upon operating the same keys, signals different from those sent out while the operation panel is not covered with the movable panel. The movable panel is made of a flexible material or equipped with windows formed at the positions corresponding to the operation keys, and locked when it is set at the position covering the operation panel.
