In step 6), it is determined whether there is an instruction to stop displaying, and if there is an instruction, it is determined that the scrolled image information is not the desired document, and there is no need to display the entire image information. The subsequent scrolling display is canceled and the process returns to the above (S81) to execute the page turning search routine to display the image information of the next page. 6. The instruction to cancel the display is made by the operator's keyboard input. 6. There was no instruction to cancel the display. If so, the process advances to (S87) and it is determined whether or not the display of the image information to be displayed has been completed, and if the display has been completed, the operator is asked to determine whether or not the displayed document is the desired document (388). ), if it is the desired document, the page turning search routine is ended, and if it is not the desired document, the process returns to (S81) and the page turning search routine is executed.

As mentioned above, since the display stop judgment means (S86) is provided, it is possible to stop displaying unnecessary image information and switch to displaying the next image information, thereby further speeding up the page turning search speed. .

"Effects of the Invention" As clarified in the explanation of the above-mentioned specific means and effects, the present invention provides that each time a certain amount of image information is developed in the image memory, the transferred image is transferred to the display memory. Information can be scrolled and displayed on a CRT display device, and pages can be searched continuously without changing the display screen momentarily, so it is possible to develop the entire image information of the page to be displayed into the image memory. This saves time and speeds up page turning and search. In addition, because the entire display screen changes instantaneously, the operator's ability to follow the display screen tends to be delayed, and it becomes difficult to see visually, reducing fatigue. It has an excellent effect of being able to solve the problems of conventional devices, such as causing problems.
