摘要： PROBLEM TO BE SOLVED: To change the position of the image display screen of an image display part according to the working situation and to improve the working efficiency by providing two image display parts and performing the switching between a 1st mode where both image display parts display the image data as the screens independent with each other and a 2nd mode where both image display parts display the image data as a single screen. SOLUTION: A display device consists of the image display parts 100a and 100b, a rotor 110 and a main body part 120. The rotor 110 supports the parts 100a and 100b, and the part 102 supports the rotor 110. The parts 100a and 100b display the image data which are sent from an information processor. In such a constitution, the image display screens of both parts 100a and 100b can be arranged right and left or up and down. Even in such a case, both image display screens can be arranged laterally or longitudinally. Furthermore, one of both image display screens can be set longitudinally even though the other screen is set laterally.
