Abstract

PURPOSE: To automatically perform displaying on an external display device when a mounted display device is not used by detecting the used state of the standardly mounted display device by a detection circuit and switching the use of the display device based on the detected result.
CONSTITUTION: The detection circuit 1 has a function for detecting whether the standardly mounted display device 5 is used or not. When the display device is mounted, a switch 200 is turned on and the output of a circuit becomes at low level. When the display device is detached, the switch 200 is turned off and the output of the circuit becomes at high level. Thus, whether or not the mounted display device is used is automatically discriminated, so that display signals can be automatically switched to the mounted display device or to the display device connected to the outside.
