In this display device, when specifying the target part on the CRT screen and displaying the screen, enter the page number or screen number (hereinafter collectively referred to as page) using the keys on the keyboard. I'm doing something like this. The operation procedure in this case is executed based on the flowchart shown in FIG. Usually, it is rare for an operator or the like to accurately memorize the page number that describes the contents to be displayed on the document, and this is often a rather vague memory. Therefore, first, in step 200, enter the page number of the appropriate page of the document (for example, all 200 pages) by pressing the keys on the keyboard (for example, 1, 2, 3, ENTER) and specify 123 pages. .. Next, in step 202, the contents of the designated P.123 input in step 200 is displayed on the CRT screen on the CRT screen. Next, at step 204, the contents of P.123 displayed at step 202 are checked, and if the page is the target page, this program is terminated by pressing the (OK) key. If it is different from the target page in step 204 (the probability that it is different from the target page at this time is extremely large), the (OK) key is not pressed, and it is designated as the page display before or after step 206. The previous page move key (PREV: Previous) or the next page move key (NEXT) key is entered. Then, it is determined whether the target page is the previous page or the subsequent page of the currently displayed P.123, and the (PREV) key or the (NEXT) key is pressed to shift to step 208. In step 208, based on the (PREV) key or (NEXT) key pressed in step 206, the contents of P.123 displayed in step 202 are changed, that is, the contents of P.122 or P.124 are changed. Display on the CRT screen. Next, the process proceeds to step 210, and if the contents of P.122 or P.124 displayed in step 208 is checked and the page is the target page, the (OK) key is pressed to end this program. .. If the page is not the target page in step 210, the (OK) key will not be pressed, and the (PREV) key or (NEXT) key input standby state in step 206 above or the page number input standby in step 200 above It is in a state. Then, if the (PREV) key or the (NEXT) key is pressed, the process proceeds to step 208 described above, and if it is determined that the page is far from the target page and the page number is input, the above described The process proceeds to step 202 of. Then, the same process is repeated to sequentially display the contents of the designated pages, so that the target page is searched and displayed on the CRT screen.

 Hereinafter, the present invention will be described based on specific embodiments. FIG. 1 is an overall configuration diagram showing a display device according to the present invention. The microcomputer 10 constituting the display device is mainly composed of a CPU 11, a ROM 12 for storing a control program and a RAM 13 for storing various data. In the page content storage area 131 that achieves the page content storage means of the RAM 13, as a document composed of a plurality of pages, for example, the entire content of the drawing consisting of 200 pages is stored page by page. .. Further, in the page outline storage area 132 which achieves the content limiting storage means of the RAM 13, an outline such as a characteristic part based on the contents of the drawing consisting of all 200 pages is stored page by page. A CRT display device 21 as a display and a keyboard 22 are connected to the CPU 11 of the microcomputer 10.

Next, a description will be given based on a flow chart of FIG. 2 showing a processing procedure of the CPU 11 used in the apparatus of this embodiment. First, on the screen of the CRT display device 21, as shown in FIG. 3 (a), a page position in the thickness direction of a drawing consisting of a total of 200 pages, which is a document composed of a plurality of page numbers. Is displayed so that it can be specified by the visual positional relationship. That is, the drawings consisting of all 200 pages are displayed in a stacked state, and the designated position in the thickness direction is indicated by the cursor. Here, as a characteristic of human memory ability, when it comes to remembering where the target page of a drawing consisting of all 200 pages is, it is rare when the page number itself is stored, and where about the thickness of the entire document. In many cases, it is remembered as a visual image.

Therefore, in step 100 of achieving the page position designation means, the current designated position, which is the page position to be displayed as the page position designation, is displayed on the keyboard 22 by the visual positional relationship in the thickness direction of the drawing. Use the page move key (up arrow: up arrow) key or the back page move key (down arrow: down arrow) key to move and specify. Then, the current designated position and the current designated page (for example, page 123) are displayed on the cursor described above. Next, the process proceeds to step 102 for achieving the designated page display means, and the entire contents of P.123 designated in step 100 are displayed on the screen of the CRT display device 21 based on the page contents storage area 131 stored in the RAM 13. Displayed above.

If it is different from the target page in step 104, the (OK) key is not pressed, and the previous page display designating key (right arrow: right arrow) key or the rear page display designating key in step 106 is pressed. There is a certain (left arrow: left arrow) key input state. Then, it is determined whether the target page is the previous page or the next page from the currently displayed P.123, and the (right arrow) key or (left arrow) key is pressed to move the page move display means. Go to step 108 to achieve. In step 108, the page summary storage area stored in RAM 13 is changed to the contents of P.123 displayed in step 102 based on the (right arrow) key or (left arrow) key pressed in step 106. The outline of each page based on 132 is confirmed, and the pages are sequentially moved and displayed at the highest possible speed. In the processing of steps 106 and 108 described above, the screen is displayed on the CRT display device 21 as shown in FIG. That is, the current display page and the outline based on the page number are displayed one after another on the screen of the CRT display device 21 as if the user continues searching by turning the (right arrow) key or the (left arrow) key. It Then, when the summary that seems to be the target page is displayed, release your finger from the (right arrow) key or the (left arrow) key. Then, the process proceeds to step 110, and the outline of the current display page stopped as the stop page display is changed to the entire contents of the page displayed on the screen of the CRT display device 21. Then, the process proceeds to step 112, and if the content displayed in step 110 is the target page, the program is terminated by pressing the (OK) key. If the page is not the target page in step 112, the (OK) key will not be pressed, and the (right arrow) key or (left arrow) key input standby state in step 106 or the above (up) (Arrow) key or (Down arrow) key input standby. Then, when the (right arrow) key or the (left arrow) key is pressed, the screen returns to the display screen of FIG. 3 (b), the process proceeds to step 106 described above, and the page is far from the target page. When it is determined that the (up arrow) key or the (down arrow) key is pressed, the screen display of FIG. Then, the same process is repeated to sequentially display the contents of the designated pages, so that the target page is searched and displayed on the screen.
