Abstract: There is an information input/output apparatus for displaying information to a display such as a LCD by instructing and operating an input device such as a transparent flat touch panel arranged on the display. The apparatus has a display controller for allowing the display to display a display area pattern for instructing that information which was input from the input device is displayed by the display on a page unit basis. A first pattern to roughly instruct a page, a second pattern to instruct the pages before and after the present page position, and a third pattern to instruct a page by directly inputting a page number are displayed in the display area pattern. The display controller discriminates which one of the first, second, and third patterns is indicated by the instruction operating position of the input device and displays the information of the corresponding page to the display. The document information can be displayed on a display screen on a page unit basis and the operator can freely instruct and display an arbitrary page through the input device.

Description: BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an information input/output apparatus having an input apparatus which faces a display screen of a display apparatus and, more particularly, to an information input/output apparatus in which document information can be displayed on the display screen on a page unit basis and an operator can freely designate and display an arbitrary page through the input apparatus. Related Background Art Hitherto, in a document processing apparatus such as a word processor or the like which can output document information on a page unit basis, there is an apparatus which executes a display of a desired page by operating a special picture plane updating key, a scroll key, or a cursor moving key or an apparatus which directly inputs a page number and can display document information of the page of such a page number. However, in the above apparatus in which the special picture plane updating key, scroll key, or cursor moving key is operated, a key operation must be performed many times in order to move from a page which is displayed at present to a page which is away therefrom, so that extremely troublesome operations are necessary. On the other hand, in a document processing apparatus which directly inputs and displays a page number, in the case where after a page number was largely jumped, and the page number is again returned to the original position or the like, the page number must be input many times, so that it is also extremely troublesome. Although there is also an apparatus which commonly uses the above two operations, those operations are independent and completely different. Therefore, it is difficult to understand the operations, they are complicated, and an operating performance deteriorates. SUMMARY OF THE INVENTION It is an object of the invention to provide an information input/output apparatus in which there is no need to execute key operations so many times in order to move from a page which is displayed at present to a page which is away therefrom. It is another object of the invention to provide an information input/output apparatus in which there is no need to input a page number so many times in order to display information of a desired page. Still another object of the invention is to provide an information input/output apparatus in which troublesome operations are unnecessary in order to display information of a desired page. Further another object of the invention is to provide an information input/output apparatus in which a plurality of methods can be used in order to display information of a desired page. The invention is set forth in claim 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail hereinbelow with reference to the drawings. Fig. 1 is an external perspective view of an information input/output apparatus according to the embodiment of the invention. Reference numeral 1 denotes an information input/output apparatus main body. An input/output section 2 in which a liquid crystal display panel and a digitizer are integratedly formed is formed on an upper surface of the information input/output apparatus. Information can be input to the input/output section 2 by using a pen 3. Fig. 2 is a block circuit diagram constructing the information input/output apparatus. Reference numeral 4 indicates an ROM (Read Only Memory). Various control programs including a page jump processing program, which will be described hereinafter, a result of the recognition of a character, a character pattern to be output, and the like have been stored in the ROM 4. A program for character recognition is also obviously included in the above various processing programs. Reference numeral 5 denotes a CPU (Central Processing Unit) which controls the whole apparatus in accordance with the various control programs stored in the ROM 2. Reference numeral 6 indicates an RAM (Random Access Memory) which is used as a work area of the CPU 5. The RAM 6 also has an area to store document information which was input from the digitizer, which will be described hereinafter, or the like. Reference numeral 7 denotes a display comprising a liquid crystal display or the like constructing the input/output section 2. Reference numeral 8 indicates a transparent digitizer (touch panel) of, for example, the resistance film type which similarly constructs the input/output section 2. A figure which was traced on the display 7 is displayed by tracing the upper surface of the digitizer 8 by using the pen 3. On the other hand, when a proper character is traced and input to the digitizer, the character is converted into the regular character pattern and displayed in accordance with the character recognizing program in the ROM 4. An external memory such as an IC card (ICC) 9 can be also connected. A practical operation of the page jump processing in the information input/output apparatus constructed as mentioned above will now be described hereinbelow. Fig. 4 is a diagram showing a display screen of the input/output section 2 to execute the page jumping operation. Reference numeral 41 denotes a display screen which displays a present page and 42 indicates a window area for a page operation. The window area is called a page operation area hereinbelow. Reference numeral 43 denotes a present page number indication and 44 indicates a page designation knob indication to roughly designate a page. According to the embodiment, an arbitrary page among pages 1 to 99 can be roughly designated by disignition the page designation knob indication 44 and moving it to the right or left with a pen or the like. Reference numerals 45 and 46 denote button indications to shift the display content from the present page to the page before or after the present page. When the button indication 45 is designated the display content is shifted to the page of the page number which is smaller than the number of the present page by one. When the button indication 46 is instructed, the display content is shifted to the page of the page number which is larger than the number of the present page by one. Reference numeral 47 denotes a display window which displays the instructed page number. A page can be also directly designated by rewriting the number in the display window 47 by using the pen. On the other hand, the display window 47 interlockingly displays the designation result even by the designation operation of the page designation knob indication 44 or the button indication 45 or 46. Reference numeral 48 denotes a stop instructing button indication. The page operation area 42 can be closed by instructing the stop instructing knob indication 48 without moving the page. Reference numeral 49 indicates an execution button indication to execute the jumping operation to the page displayed in the display window 47 as a result of the designation operation of the page designation knob indication 44 or the button indication 45 or 46. Fig. 3 is a flowchart showing a page jump processing program which is activated when the page operation area 42 is traced by the pen. In step S1, coordinates (X, Y) which are pressed by the pen at present are first substituted for a variable Z. It is now assumed that the coordinates of the left upper corner on the display screen are set to the origin and the coordinates of the right lower corner are set to (319, 127), and the coordinates (X, Y) of the pen are controlled so as to be updated every 16 msec. In the next step S2, the values which were substituted for the coordinate variable Z mentioned above are compared to an area H which is shown by a left upper coordinate H L and a right lower coordinate H R of the execution button indication 49 shown in Fig. 4, thereby discriminating whether the coordinate Z exists in the area H or not. If the coordinate Z exists in the area H, step S7 follows and the page jumping operation is executed, the page number displayed in the display window 47 is set to a display page PG, and an object to be edited is switched to data of the page number PG. If the coordinate Z doesn't exist in the area H, the processing routine advances to step S3. In step S3, a check is made to see if the coordinate Z exists in an area G shown by the stop button indication (48 in Fig. 4) to instruct the stop of the page jumping operation or not. If the coordinate Z exists in the area G, nothing is executed and the processing routine is finished. If the coordinate Z doesn't exist in the stop button indication area G, the processing routine advances to step S4. Similar processes are executed in steps S4 to S6 hereinbelow. In step S4, a check is made to see if the coordinate Z exists in an area D shown by the page designation knob indication 44 to roughly designate a page or not. In step S5, a check is made to see if the coordinate Z exists in areas E and E' of the button indications 45 and 46 or not. In step S6, a check is made to see if the coordinate Z exists in an area F of the display window 47 or not. If the coordinate Z doesn't exist all of the above display areas, the processing routine is returned to step S1 and the above processes are repeatedly performed. If it is determined that the coordinate Z exists in each of the above display areas, step S8 follows. In step S8, the apparatus waits until the pen is pulled up and the page number PG displayed in the display window 47 is updated in accordance with the page designation method corresponding to each of the areas. Then, step S9 follows and the updated page number PG is again displayed in the display window 47. After that, the processing routine is returned to step S1 and the above processes are repeated. By the above operations, a combination of a plurality of kinds of pages can be designated in one page operation area and each of the designation displays mutually interlockingly changes, so that an operating performance of the page designation by the operator is extremely improved. [Another embodiment] Fig. 5 is a diagram showing the display screen of the input/output section 2 to execute the page jumping operation according to another embodiment and shows an example in which a display layout of the input/output section 2 was changed. Since a block circuit diagram of an information processing apparatus main body is substantially the same as that in Fig. 2, its explanation is omitted. In Fig. 5, reference numeral 51 denotes an input display screen of the present page and 52 indicates an operation bar indication to roughly designate a page. A left edge of the operation bar indication 52 is set to 1 and a right edge is set to 99. A black portion is commonly used as a present page display and a designation knob. Reference numerals 53 and 54 indicate designate display areas to shift a display content to the page before or after the present page and show areas which are displayed in a state in which the page was turned over. Reference numeral 55 denotes an area in which the present page or the designated page is displayed and a desired page number is directly input by using a character recognition. Reference numeral 56 indicates a window indication which is displayed when the page designation operations 51 to 55 are executed. A stop instructing button indication 57 and an execution button indication 58 which perform functions similar to those in the above embodiment are provided in the window indication 56. As in the above embodiment, according to a display layout of the input/output section 2 in the embodiment, a large area of the edition area in the input display screen is not occupied by the page operation area and space is not used in vain. As described above, according to the information input/output apparatus of the invention, a combination of a plurality of kinds of pages can be designated in one page operation area displayed on the display screen and each of the designation displays is mutually interlockingly changed, so that there is an effect such that the operating performance of the page designation by the operator is extremely improved. There is an information input/output apparatus for displaying information to a display such as a LCD by instructing and operating an input device such as a transparent flat touch panel arranged on the display. The apparatus has a display controller for allowing the display to display a display area pattern for instructing that information which was input from the input device is displayed by the display on a page unit basis. A first pattern to roughly instruct a page, a second pattern to instruct the pages before and after the present page position, and a third pattern to instruct a page by directly inputting a page number are displayed in the display area pattern. The display controller discriminates which one of the first, second, and third patterns is indicated by the instruction operating position of the input device and displays the information of the corresponding page to the display. The document information can be displayed on a display screen on a page unit basis and the operator can freely instruct and display an arbitrary page through the input device.
