<p>PURPOSE:To scroll an entire image in a single direction by providing a 2nd scroll display means to project the image data following the image data on a desired area on each display device except the prescribed on in response to the scroll of a 1st scroll display means. CONSTITUTION:The image data 11 on a desired part of an image memory 1 is transferred to the buffer memories 12, 15 and 16 and then sent to the CRT display devices 10, 13 and 14 respectively. When the scroll switches 19 - 21 are laterally operated, the areas of the image data 11, 17 and 18 of the devices 10, 13 and 14 are laterally scrolled. When the changeover switches 22 and 23 are connected to a terminal (b), the scroll commands of a scroll switch 19 are sent to the buffer memories 15 and 16. Under such conditions, the image data on a desired area is scrolled by the switch 19 and projected on the prescribed display device 10 among those multi-fold image data stored in the memory 1. Thus the images following an optional one can be projected at one time and at the same time an entire image can be scrolled in a single direction.</p> |
