A selection candidate display method, a selection candidate display device, and an input/output device are provided. When a number of receivable broadcasting stations is not “4” or less, a controller allocates the receivable broadcasting stations to three segmented logical areas among four segmented logical areas, allocates a scroll area to the remaining one logical area, and displays the channel numbers of the allocated receivable broadcasting stations and information indicating the scroll area, for example, “S” in the respective logical areas of a circle pad. When the logical area to which the scroll area is allocated is operated, the controller moves the scroll area to the adjacent logical area and allocates the next receivable broadcasting station after the broadcasting station allocated to the remaining logical area among the logical areas adjacent to the scroll area, to the logical area which was the scroll area.
