摘要

PURPOSE:To improve the handling facilitation of a display device which is used for the window service jobs, etc., by provide a conversion display control part which inverts a conversion display screen by 180 deg. with a 180 deg. conversion command. CONSTITUTION:An input information analyzing part 2 checks and decodes the 180 deg. conversion information instructed from an input part 1 and then outputs the conversion information to a conversion display control part 3. The part 3 inverts the screen information to be displayed by a received 180 deg.C conversion command and sends this control output signal to a visible display part 4 to display an inverted image at the part 4. In such a constitution, the display screens can be inverted when a terminal operator pushes a conversion key as necessary in such a case where two persons are using a display device opposite to each other for the window service jobs, etc. Thus the contents o the display screens can be confirmed with no mistake.
