Abstract
Abstract A printer which is permitted to be mounted with an interface unit for connecting the printer to a computer, without the need of removing a printer case. A unit accommodating space (13) arranged to receive an extension interface unit and an integrated circuit card (50) is formed in the printer case (10) which is provided with a first connector (30) connected to a standard interface unit accommodated in the printer. The accommodating space defined by partition walls (14-17) is isolated from printer constituent parts, such as a controller printed-circuit board, disposed within the printer case. A second connector (41) and a socket (51) respectively arranged to be mounted with the extension interface unit and the integrated circuit card are disposed to be exposed to the unit accommodating space, whereby the extension interface unit and the integrated circuit card can be easily mounted to the printer, without the need of removing the printer case and without being brough into contact with the printer constituent parts.
