e-Ray Tube), a main control device that controls image information such as characters and figures displayed on this display device, and a KEY board that allows the user of the device to input image information. ing. The display device has a rectangular display section, and this display section is fixed to either a vertically long screen or a horizontally long screen and is provided within the display device.

0003

However, in the above-mentioned conventional information processing apparatus, since the display section of the display device made of a CRT is fixedly provided on a vertically or horizontally long display screen, it has the following problems. ing.

In other words, in the case of an information processing device in which the display section of the display device is fixed to a horizontally long screen, it is possible to output a large number of characters in the horizontal direction, so it is possible to create a document in the horizontal A4 size document format. When doing so, the entire A4 size document can be output on one screen, making it possible to increase the efficiency of document creation.

[0005] However, there are various document formats such as A4 size and B4 size, and
There are two types of each of the above sizes: horizontal and vertical. Therefore, for example, when creating a document in A4 size document format that is placed vertically, it is not possible to output the entire A4 size document on one screen because the number of digits in the vertical direction of the display section is small. This will reduce the efficiency of creation.

[0006]In recent years, therefore, an information processing device has been proposed in which the display section of the display device can be rotated between a vertical position and a horizontal position. Depending on the horizontal layout, the user of the device must operate the KEY board to set the display screen to portrait or landscape. When setting the format, the user must compare the set format on a portrait screen and a landscape screen and decide which display screen is easier to view, and then switch the display between portrait and landscape. On the other hand, there is a problem in that a cumbersome display image setting operation is forced.

[0007]

By comparing the number of characters using this vertical and horizontal switching evaluation method,
and a rotating means for switching the rotating position of the display unit to the display screen with the largest number of characters that can be displayed.

[0011]

According to the structure of claim 1, the number of characters that can be displayed in a vertically long and horizontally long display screen is compared and calculated from an arbitrarily set format by the vertical and horizontal switching evaluation means, and based on the comparative calculation of the number of characters, An instruction is issued to switch the display section to a rotation position corresponding to the display screen with the largest number of characters that can be displayed. Therefore, for an arbitrarily formatted document, a vertically long or horizontally long display screen, which is more efficient for document creation, is automatically selected.

Note that the format setting routine stored in the ROM 11a can be set in any format by inputting from the KEY board 5.

The display unit 3 includes a rectangular liquid crystal display panel 3a. This liquid crystal display panel 3a is provided with a first panel frame 3b surrounding the outer periphery and a second panel frame 3c covering the rear surface. 3c has one corner removed to prevent interference between the display unit 3 and the mounting table 1 when the display unit 3 is rotated. The display unit 3 can be arranged in a vertical position and a horizontal position (double-dashed line in FIG. 2) by rotating in the A1-A2 direction.

Further, at the lower end of the display unit 3, a vertical/horizontal detection sensor 20 is provided for detecting whether the display unit 3 is arranged vertically or horizontally. This vertical/horizontal detection sensor 20 is equipped with a push-type microswitch to detect that the side receiving heavy pressure is the bottom side, and the detection signal from the vertical/horizontal detection sensor 20 is transmitted via an interface circuit (not shown). CPU10

It is formed as a vertical and horizontal switching evaluation means. Note that the above character count evaluation routine and speed evaluation routine are
Depending on the input from the KEY board 5, one of the evaluation routines is selected and executed.

[0020] The above character count evaluation routine compares and calculates the number of protruding characters on both vertical and horizontal display screens based on the number of characters per line and the number of lines in the set format, and displays the display according to the display screen with the smaller number of protruding characters. If the arrangement state of the unit 3 differs from the actual arrangement state of the display unit 3 detected by the aspect detection sensor 20, an instruction to switch the display screen is displayed on the liquid crystal display panel 3a of the display unit 3. ing.

[0021] The above-mentioned comparative calculation of the number of characters protruding from the display screen is performed by assuming that A is the maximum number of lines that can be displayed on the display screen when the display unit 3 is placed horizontally, as shown in Fig. 5(a). , if the maximum number of digits that can be displayed is B, then when the display unit 3 is placed vertically, the maximum number of lines that can be displayed is B, and the maximum number of digits is A. And Figure 5(B)
The number of protruding characters of the formatted document shown by the broken line is compared and calculated in both the horizontal orientation of the display unit 3 shown by the thin line and the vertical orientation of the display unit 3 shown by the thick line. (In the figure, a indicates the number of protruding characters in vertical orientation,
b indicates the number of protruding characters in horizontal orientation) For example, as shown in Figure 5(c), if the number of characters in one line of the document is less than or equal to A, and the number of lines in the document is greater than A, the display unit 3 is selected as a display screen with a small number of protruding characters, and as shown in Figure 5(d), if the number of characters per line of the document is greater than A and the number of lines of the document is less than or equal to A, the display screen is The horizontal position of the unit 3 is selected as a display screen with a small number of protruding characters. In addition, as shown in FIG. 5(e), the number of characters in one line of the document is greater than A, and the number of lines in the document is A.
If the size is larger, the vertically placed display unit 3 is selected as a display screen with fewer protruding characters, and as shown in FIG.
As shown in (f), if the number of characters per line of the document is A or less, and the number of lines of the document is A or less, the distance between the guidance (document information) displayed at the bottom of the display screen and the document is The closer the display unit 3 is placed horizontally, the less eye movement is required, the less tiring, and the higher the work efficiency is, so the horizontal position of the display unit 3 is selected as a display screen with fewer protruding characters.

[0022] The above speed evaluation routine compares and calculates the scrolling processing time of both the vertical and horizontal display screens for a formatted document, and displays the display according to the display screen that requires less scrolling processing time. If the arrangement state of the unit 3 differs from the actual arrangement state of the display unit 3 detected by the aspect detection sensor 20, an instruction to switch the display screen is displayed on the liquid crystal display panel 3a of the display unit 3. ing.

Note that in the comparison calculation of the processing time for scrolling as described above, when the display unit 3 is placed vertically, the processing time for horizontal scrolling is calculated as shown in FIG. 6(a), and , when the display unit 3 is placed horizontally, the processing time for vertical scrolling is calculated as shown in FIG. 6(b). (In FIGS. 6(a) and (b), respectively,
(The display screen is shown with a double line, and the document is shown with a broken line.) In the above configuration, the process of setting the display screen vertically and horizontally by the information processing apparatus according to this embodiment is described below based on the flowchart shown in FIG. explain.

First, the number of characters per line of the document is set by input from the KEY board 5 (S1), the number of lines per page is set (S2), and the format is set. Next, K
Based on the input from the EY board 5, it is selected whether the vertical and horizontal settings of the display screen should be evaluated based on the number of characters or the speed (S3).

If the above selection is to be evaluated based on the number of characters (S4), a character number evaluation routine in the ROM 11a is executed. Then, the number of characters that protrude from the document when the display unit 3 is placed vertically is calculated by the character count evaluation routine (S5), and the number of characters that protrude from the document when the display unit 3 is placed horizontally is calculated (S6).
), then the number of protruding characters in the vertical orientation and the number of protruding characters in the horizontal orientation are compared and calculated (S7), and the arrangement state of the display unit 3 corresponding to the display screen with the smaller number of protruding characters is selected.

Next, the arrangement state of the display unit 3 selected as described above is compared with the actual arrangement state of the display unit 3 detected by the vertical/horizontal detection sensor 20, and if these arrangement states are different, , an instruction to switch to the vertical orientation (S8) or horizontal orientation (S9), which is the orientation of the display unit 3 selected by the character count evaluation routine described above, is displayed on the liquid crystal display panel 3a of the display unit 3.

On the other hand, if the selection in S3 is to be evaluated based on speed (S10), the speed evaluation routine of the ROM 11a is executed. Then, the speed evaluation routine calculates the processing time for horizontal scrolling of a document with the display unit 3 in portrait orientation (S11), and also calculates the processing time in vertical scrolling of a document in landscape orientation of the display unit 3 (S11). S12) Then, the processing time for horizontal scrolling and the processing time for vertical scrolling are compared and calculated (S13), and the arrangement state of the display unit 3 is determined according to the display screen that requires less processing time for scrolling. is selected.

Next, the arrangement state of the display unit 3 selected as described above is compared with the actual arrangement state of the display unit 3 detected by the aspect detection sensor 20, and if these arrangement states are different, , an instruction to switch to the vertical orientation (S8) or horizontal orientation (S9), which is the orientation of the display unit 3 selected by the speed evaluation routine described above, is displayed on the liquid crystal display panel 3a of the display unit 3.

As a result, for a document that has been arbitrarily formatted, the number of characters protruding from both the vertical and horizontal display screens is compared and calculated by the character count evaluation routine in the ROM 11a, and based on this, the display unit with the smaller number of characters protruding from the display screen is selected. The arrangement state No. 3 is automatically selected. If the arrangement state of the display unit 3 selected by the above-mentioned character count evaluation routine is different from the actual arrangement state of the display unit 3 detected by the aspect detection sensor 20, the liquid crystal display of the display unit 3 is automatically An instruction to switch the display unit 3 is displayed on the display panel 3a to prompt the user of the device to switch the display unit 3 to an arrangement state that is more efficient for document creation.

Further, in this information processing apparatus, a motor (not shown) is provided in the support casing 2 that supports the display unit 3 via the support member 4 as a rotation means for rotating the display unit 3 in the A1-A2 direction. In addition to arranging R
