ABSTRACT:
A dual purpose printer interface device includes a printer interface circuit connected to a host computer and a printer connector to which a printer is to be connected. An adaptor can connect removably a joystick to the connector. A joystick interface circuit is connected to the computer and the connector. A first selecting unit connects electrically the computer to the printer and joystick interface circuits and is operable selectively in a first mode, wherein the printer interface circuit is connected electrically to the computer and the joystick interface circuit is disconnected from the computer, and in a second mode, wherein the joystick interface circuit is connected electrically to the computer and the printer interface circuit is disconnected from the computer. A second selecting unit connects electrically the connector to the printer and joystick interface circuits. The second selecting unit is operable to connect electrically the printer interface circuit to the connector and to disconnect the joystick interface circuit from the connector when the first selecting unit is operated in the first mode and to connect electrically the joystick interface circuit to the connector and to disconnect the printer interface circuit from the connector when the first selecting unit is operated in the second mode.
