DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration in the case where the present invention is applied to a document creating apparatus, for example. In FIG. 1, the input unit 21 has a keyboard 21a for inputting various kinds of information necessary for creating a document and a mouse 21b as a pointing device. Input control unit 22
Controls the input of the input unit 21. The control unit 23 controls the entire device. The display control unit 24 controls the display of the display unit 25. The display unit 25 is, for example, a liquid crystal display (LCD) device. The memory 26 stores document information including a plurality of pages and various kinds of information necessary for creating a document. The page management unit 27 manages the total number of pages of the document information, and here calculates the page break width of the scroll bar 32 (see FIG. 2) based on the total number of pages. The scroll control unit 28 performs page scroll processing and the like according to the operation of the scroll bar 32 (see FIG. 2).

FIG. 2 is a diagram showing the structure of the display screen of the embodiment. In FIG. 2, the window screen 31 is for displaying the document information stored in the memory 26 in page units. On this window screen 31, a scroll bar 32 and an elevator 33 are displayed as a scroll operation unit. In addition, arrow icons 34 a and 34 b for moving the elevator 33 are displayed at both ends of the scroll bar 32. Since the scroll bar 32, the elevator 33, and the arrow icons 34a and 34b are the same as those in the conventional art, their description will be omitted.

In this embodiment, on the window screen 31, a boundary line 35 indicating a page break is displayed on the scroll bar 32 together with the number of pages. The boundary line 35 serves as a guide when the elevator 33 is moved. The number of pages is displayed in each area of the scroll bar 32 divided by the boundary line 35.

Next, the operation of the embodiment will be described.

As shown in the flow chart of FIG. 4, when displaying the document information consisting of a plurality of pages stored in the memory 26, the control section 23 first sets the total number of pages of the document information in the page management section 27. (Step A1). The page management unit 27 calculates the page break width based on the total number of pages (step A2). In this case, if the page break width is W, the length of the scroll bar 32 is L, and the total number of pages is S, the page break width W can be obtained by the following calculation formula (1).

W = L / S (1) The scroll control unit 28 displays a boundary line 35 on the scroll bar 32 based on the page break width (step A3), and scrolls separated by the boundary line 35. The number of pages is displayed in each area of the bar 32 (step A
