Abstract

PURPOSE:To attain the display of various objects by providing a means which detects the direction of an output means and a direction input means which informs an arithmetic processing means of the information on the detection means. CONSTITUTION:When an information processor is set laterally by a user, a lateral direction detecting SW 4 is pushed with no push of a longitudinal direc tion detecting SW 3. Meanwhile the SW 3 is pushed with no SW 4 when the processor is set longitudinally. Thus both SW 3 and SW 4 work exclusively to each other and never pushed at one time. An input port 6 judges a longitudi nal state of the processor designated by the user and informs a CPU 9 of this fact when the SW 3 is pushed. Meanwhile a lateral state of the processor desig nated by the user is judged with push of the SW 4 and informs the CPU 9 of this fact. The CPU 9 outputs the lateral or longitudinal state information to a longitudinal/lateral designation circuit 7 based on the information of the port 6. At the same time, a display control circuit 8 displays the processing results, etc., of the CPU 9 on a liquid crystal display 2.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is applicable to paper specifications for word processors, etc.
Alternatively, the present invention relates to a method for specifying a horizontal paper orientation, and a display device or an input device that implements the method.

[Conventional technology]

It is generally known that with conventional word processors (hereinafter abbreviated as word processors), etc., you specify the paper to be used by following the menu displayed by the device and inputting the paper size and paper orientation (portrait, landscape, etc.) from the keyboard. There is.

As described in Japanese Patent Application Laid-Open No. 56-9787, it is known that the display device is rotated 90 degrees in accordance with the direction of the paper for easy viewing. Hereinafter, a conventional display device will be explained using FIGS. 8 to 10.

FIG. 8 shows a configuration diagram of a conventional 90-degree rotatable display device, in which 40 is a CRT, 41 is a CRT cover, 42 is a pedestal, 46 is a bearing that allows the CRT 40 to rotate, and 44 is a A yoke 45 deflects the electron beam of the CRT 40, and a switch 45 detects the direction of the CRT 40. The yoke 44 is fixed to the pedestal 42, and scans the electron beam from the back to the front with respect to the paper surface, and gradually scans it from the top to the bottom. The CRT40 displays electron beams as visible information, and the CRT40 and CRT41 are
It is supported by a bearing 43 and has a rotatable structure around the center line. Therefore, the display surface can be rotated to display the horizontally long display in FIG. 9(a) and the vertically long display in FIG. 9(b).

At this time, the scanning electron beams are both in the same direction, but their deflection widths X and y are different. Additionally, scan
The linearity of the u beam also differs depending on the display direction. Therefore, as shown in FIG.
A method has been adopted in which each control voltage value inputted to the controller 1 is changed over by a switch 45 indicating portrait or landscape display, and the deflection width and linearity of each is corrected. in this way,
Although a plurality of variable resistors are required to generate vertical and horizontal control voltages, a vertical or horizontal display screen can be displayed simply by rotating the CRT.

[Problem to be solved by the invention]

The above-mentioned prior art is a portrait or landscape display device, and does not take into consideration the point of specifying the paper direction in a word processor or the like, and requires a separate input means for specifying the paper direction.

SUMMARY OF THE INVENTION An object of the present invention is to simplify a method for specifying paper orientation in a device such as a word processor.

Another object of the present invention is to provide a display device f' whose display direction changes depending on the paper direction.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a detection means for detecting the orientation of a display device or an input device, and determines the paper direction based on the result of the detection means.

Further, the detection means may be an input means for determining the paper direction.

In order to achieve the above-mentioned other objects, the segment drive means of the flat display device is constituted by a switching means for switching the column drive means depending on the paper direction.

[Effect]

The detection means detects the orientation of the display device or the input device, and outputs information as to whether the orientation is portrait or landscape. The device reads this, recognizes it as the designated paper direction, and processes it, which simplifies the designation of the paper direction because it is not necessary to specify the paper direction using a keyboard according to a menu.

Furthermore, although the input means has the same function as the detection means, it is operated intentionally by the user of the device or as a necessity when using the device. Therefore, like the detection means, specifying the paper direction is simplified.

The switching means in a flat display device capable of displaying images by switching the vertical/horizontal display direction functionally switches the segment driving means and the column driving means. Therefore, it is possible to realize a flat display device in which the segments and columns of the flat display device can be interchanged, allowing vertical and horizontal display directions.

〔Example〕

Hereinafter, an example of the present invention will be explained in detail using FIG. Figure 1 shows a configuration diagram of an information processing device, in which 1 is a touch panel, 2 is a liquid crystal display device, 6 is a vertical direction detection switch (hereinafter referred to as SW), 4 is a horizontal direction detection SW, and 5 is a Touch panel 10 input processing circuit, 6 is an input port for vertical direction detection SW3 and horizontal direction detection SW4, 7 is a vertical/horizontal designation circuit for specifying the display direction, 8 is a display control circuit, 9 is a central processing unit (hereinafter referred to as CPU) ), 10 indicates memory.

The information processing device performs input processing 5 and input port information 1c.
Processed using PU 9 and memory 10, vertical/horizontal designation circuit 7
is output to the display device f2 via the display control circuit 8. The touch panel 1 is fixed on the liquid crystal display device 2, and the CPtJ9 obtains information through the input processing 5 at the portion where the user indicates a response to a message or the like output from the information processing device. The input port is used to inform the state of the vertical direction detection SW3 and the horizontal direction detection SW4 to fiicPL]9. The orientation of the touch panel 1 and the liquid crystal display device 2 is detected as follows. The back surface of the liquid crystal display device 2 is shaped like a square pyramid, and the vertical direction detection SW3 and the horizontal direction detection SW4 are arranged on a surface that is not a diagonal surface of the square pyramid. When an information processing device with such a shape is used on a desk, as shown in FIG. 2(a), when the user places the device in the horizontal direction, the horizontal direction detection SW4 is pressed, The detection SW3 does not touch the desk and is not pressed because the back is square.On the other hand, when it is placed vertically as shown in Figure 2(b), the vertical detection SW5 is pressed and is not pressed horizontally. Direction detection SW4 is not pressed. In this way, vertical direction detection SW3 and horizontal direction detection SW4 operate exclusively and are not pressed at the same time. When vertical direction detection SW5 is pressed, the input portrait The CPU determines that the user has specified it.
Let 9 know. On the other hand, if the horizontal direction detection SW4 is pressed, it is determined that horizontal orientation is specified, and CP[J9 is notified. (:PL] 9) Based on the information of the input port B, horizontal or vertical information is output to the vertical/horizontal designation circuit 7.

The display control circuit 8 is a vertically long or horizontally long liquid crystal display device 2K depending on the content of the vertical/horizontal designation circuit 7.

The processing results of the CPU 9 are displayed. In this manner, the user can inform the operating software or the like of the orientation by the orientation of the touch panel 1 and the liquid crystal display device 2.

In this embodiment, the touch panel 1t is described as a human-powered device, but a handwritten character recognition device using a digitizer or the like or a keyboard may also be used.

Also, instead of the liquid crystal display device 2, a printing device may be used (A
.

Furthermore, although the touch panel 1 has been described as being fixed on the liquid crystal display device 2, it is not particularly necessary to be fixed, and each may exist independently. It does not need to be attached to the liquid crystal display device 2, and may be attached to an input device such as the touch panel 1.

In addition, there may be a plurality of detection SWs, and as shown in FIG. It has a very good configuration to operate.

Next, an embodiment of the second invention will be described using FIG. 4.

FIG. 4 shows a configuration diagram of a liquid crystal display device capable of rotating display by 90 degrees. In the figure, reference numerals 11 and 17 are voltage selectors;
3 and 15 are signal selectors, 12 and 18 are control voltages applied to the liquid crystal, 14 and 16 are control signals, 19 is an MGs number raw acid generation circuit 0 and 21 are drivers, 22 is a liquid crystal, and 26 is an inverter.

Drivers 20 and 21 are the same driver with column and segment functions, such as Hitachi HD66.
There is 107T. The function of each driver is determined by the vertical/horizontal switching signal S, and when it is I or II, it becomes an X driver, and when it is HHII, it becomes an X driver. Vertical/horizontal switching (J
When the number S is III or II, the voltage selector 11 and signal selector 16 output the X voltage and the X driver control signal to the A driver 20, and the A driver 20 operates as an X driver. Further, the voltage selector 17 and the signal selector 15 output the X voltage and the X driver control signal to the B driver 21, and the inverter 25 outputs the X voltage and the
1 operates as an X driver in contrast to the A driver 20.

Therefore, these display devices operate as horizontally elongated liquid crystal display devices. - When the vertical/horizontal switching signal S is IHH, the voltage selector 11 and the signal selector 16 output the X voltage and the X driver control signal to the A driver 20Vc, and the A driver 20 operates as an X driver. The X voltage and the X driver control signal are outputted to the B driver 21 by the selector 17 and the signal selector 15, and the B driver 21 operates as an X driver, and the entire device operates as a vertically elongated liquid crystal display device. M signal generation circuit 1
9, since the number of scanning lines is different in a vertically or horizontally long display, the number of divisions is switched by the vertical/horizontal switching E-a S to generate an M signal suitable for liquid crystal display. With such a configuration, a vertically long or horizontally long liquid crystal display device can be constructed.

Although this embodiment has been described based on a liquid crystal display device, a display device driven by segments and columns may be used instead of a liquid crystal display device.

As described above, according to this embodiment, it is possible to easily specify the paper direction by simply changing the structure f of the apparatus, thereby making it easier for the user to use the apparatus.
