A control part of the control circuit device is formed by a control circuit section in the form of cassette having an outer end portion to which one half portion of a connector is secured. This half portion of the connector is adapted to be connected with the other half portion of the same connector mounted on an associated end of the cord. In an internal space of the printer, a receiving section for accommodating therein the cassette type control circuit section is defined, so that the control circuit section is detachably mounted through an insert port which opens at a first side of the printer different from a second side thereof along which a printing sheet is fed to the printer.
