A recording device is disclosed which has a push switch and no display. A menu item is sequentially changed out of a plurality of menu items, which are arranged in a specific order, by operating the push switch. Sub-pluralities of menu items are sequentially skipped based on the continuous operation of the push switch to quickly arrive at a desired menu item, without the need to select each and every menu item in sequential order.

A multifunctional material having a carbon-doped titanium oxide layer, which has carbon doped in the state of Ti—C bonds, is excellent in durability (high hardness, scratch resistance, wear resistance, chemical resistance, heat resistance) and functions as a visible light responding photocatalyst, is provided. The multifunctional material of the present invention is obtained, for example, by heat-treating the surface of a substrate, which has at least a surface layer comprising titanium, a titanium alloy, a titanium alloy oxide, or titanium oxide, in a combustion gas atmosphere of a gas consisting essentially of a hydrocarbon such that the surface temperature of the substrate is 900 to 1,500° C.; or by directly striking a combustion flame of a gas consisting essentially of a hydrocarbon, against the surface of the substrate for heat treatment such that the surface temperature of the substrate is 900 to 1,500° C.
