An electronic apparatus has a ball-point pen as the recording means and rotatably supports a roll of printing paper on a shaft provided on the side surface of the main body of the electronic apparatus, wherein the shaft to support the printing paper is made hollow inside, a cap is fitted in each opening at both ends of the shaft in a freely openable and closable manner so as to enable spare ball-point pens and a ball-point pen removed from a carriage of the electronic apparatus, when it is not in use, to be housed inside it.
