A keyboard with a simplified structure, which is connected to a main computer having a microcomputer in which a key map is stored therein and which generates first and second scanning signals via respective scan input lines and receives first or second scanning codes via respective scan output lines upon a key on the keyboard being operated. The keyboard includes first and second keyboard frames separated from each other, and a first key matrix assigned to the first keyboard frame and disposed adjacent thereto, for generating the first scanning code in response to the first scanning signal, and a second key matrix assigned to the second keyboard frame and disposed adjacent thereto, for generating the second scanning code in response to the second scanning signal.
