ABSTRACT:
An information output device basically comprises character output elements for visibly outputting at least one of characters such as letters, numbers, symbols, etc., a keyboard carrying thereon keys corresponding to the characters and usable for the selection of the characters, and a miniature body for containing therein the character output elements and the keyboard. Most of the size of the body is occupied by the keyboard. The character output elements may be printing devices for printing the characters on recording paper, or character display devices comprising a plurality of display elements for displaying the characters. The information output device may also include a control circuit for applying a control or driving signal to the printing devices or the display elements of the character display devices to cause the characters selected by the keys to be printed on the recording paper or to cause the display elements to successively display the characters selected by the keys. The body may also contain therein the control circuit.
