First, the operator inputs a document file name (step S1). As a result, the display control means 11 takes out the corresponding file from the storage means 10 and first reads the data of the first page (step S2). Next, the display control means 11 causes the display device 12 to display the entire first page (step S3). Here, the display screen of the display device 12 can display one page of the document. Next, an input of a next display page interval designation button (hereinafter referred to as a numeric key) 13a from the instruction means 13 is waited for (step S4), and after a certain numeric key is turned on, this key is turned off (pressed state is released). Then, (step S5), the number of updated pages corresponding to the numeral key 13a is set (step S6). For example, when the number key “2” is turned on / off in steps S4 and S5, the update page interval is 2
Every page. Here, "0" is set in advance as a page interval, and "1" to "9" are set as page intervals corresponding to the numbers.

After that, the display control means 11 performs step S
The data of the page to be displayed next is read according to the page interval set in step 6 (step S7), and input of the direction button (hereinafter referred to as direction key) 13b is waited for (step S8). When a certain direction key 13b is turned on, the display control means 11 moves the currently displayed page in the direction corresponding to the direction key to display a new page (step S9). FIG. 5 is an explanatory diagram showing this state. That is, when the right key is pressed as the direction key 13b, the current display page is moved to the right, and the next display page (the hatched portion in the drawing) is displayed on the left part of the screen.

Thereafter, when the numeric key 13a is turned on / off (steps S10 and S11), the page interval to be updated with the numeric value corresponding to the numeric key 13a is reset (step S12), and the process returns to step S7. Also,
In this step S12, "0" remains unchanged from the previous setting, and when "1" to "9" are pressed, the update page interval corresponding to that number is set. For example, if the page interval to be updated is set to 2 pages in step S6, the currently displayed page is set to 1 in step S9.
This is the page and the next display page is the third page. Then, with the right half of the screen being the first page and the left half being the third page, the direction key 13b is turned off, and step S1
When the update page interval is changed to 3 in 2, the sixth page is read as the next display page in step S7, and when the direction key 13b is turned on, the sixth page is displayed as the new page. Further, here, the first page and the third page displayed before are moved in either direction as the current display page in the same state.
In this way, by repeating the processing of steps S7 to S12, it is possible to display a plurality of pages as if turning over every updated page.

First, in step S1, a document file name is selected from a menu or the like, the first page of the corresponding document data is read from the file (step S2), and the entire first page is displayed on the display device 12 (step S3). After that, the page interval to be updated is initialized (step S4). Here, the initial setting value is "1". Then, in step S5, waiting for the button 14a to be turned on,
When the button 14a is turned on, the input device 14 is not moved (step S6), and the button 14a is turned off in this state (step S7), the page interval value to be updated is added (n = n + 1) (step S8). ), Step S5
The on-waiting process of the button 14a is returned. When the input device 14 moves with the button 14a turned on in step S5 (step S6), the data of the page to be displayed next is read (step S9), and a new page is displayed (step S10). Then, when the input device 14 further moves (step S11), the current display page is moved in that direction, and the next display page is gradually expanded and displayed.

FIG. 8 is an explanatory diagram thereof. That is, similarly to the first embodiment, the current display page moves in response to the movement of the input device 14, and the next display page (indicated by the shaded portion in the figure) appears. The arrow in the figure indicates the pointer position indicated by the input device 14. After that, when the button 14a is turned off (step S12), the process returns to the update page interval value initial setting process of step S4. Therefore, also in this embodiment, similar to the first embodiment, by repeating the processing of steps S4 to S12, the document can be displayed as if turning the page.

Next, a third embodiment will be described.

Next, the operation of the third embodiment will be described. FIG. 9 is a flowchart showing the operation. First, in step S1, the document file name is input from the keyboard or the like. As a result, the first page of the relevant document data is read from the file (step S2), and the entire first page is displayed on the display device 12 (step S).
3). After that, the page interval value to be updated is determined corresponding to the pressing force applied to the button 15a (step S4). 11
FIG. 6 is an explanatory diagram showing a relationship between a pressing force and a page interval value to be updated. Thus, if the maximum pressure is n, Pl
(N / 10) is a value for determining whether the page is updated,
n / 10 to n / 2 are page interval values to be updated = 1, n /
2 to 3n / 4 is "2", 3n / 4 to 7n / 8 is "3",
7n / 8 to 15n / 16 are predetermined such as "4". When the page interval value to be updated is determined by the pressing force applied to the button 15a, the page interval value to be updated is displayed on the display device 12 (step S5).

FIG. 12 shows this state. That is, the first page is displayed, the pointer of the input device 15 is displayed, and when the button 15a is pressed in that state, the page interval value to be updated is displayed at the position of the pointer according to the pressing force. .. Then, it waits for the input device 15 to move (step S6). When the input device 15 moves, the data of the page to be displayed next is read (step S7), and a new page is displayed (step S).
8). Then, as the input device 15 moves (step S9), the display area of the new page gradually expands. The display area of this new page is the shaded area in FIG. 12, and this operation is the same as in the first and second embodiments.
After that, when the pressing force on the button 15a disappears (step S10), the process returns to the setting process of the page interval value to be updated again (step S4). When the button 15a is pressed, the input device 15 in step S9
