The radio receiver includes a data extractor for extracting a character data from a broadcast radio wave currently being received; a detector for detecting the signal strength of a broadcast radio wave currently being received; a character pattern generator for generating a character pattern common to both an alphabetic capital and a small letters of English or of some other language in accordance with the character data signal; a character discriminator for discriminating a capital and a small letter in accordance with the character data signal; and a display for displaying a character pattern outputted from the character pattern generator in different displaying modes depending on which of a capital letter and a small letter should be displayed in accordance with the output from the control.
