DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message display system for scrolling a message on a liquid crystal display of a word processor.

[0002]

2. Description of the Related Art Heretofore, a display method of displaying a message on a display screen by scrolling a message vertically or horizontally has been often used. This method has a feature that a long sentence message can be continuously displayed on a display screen of a fixed size, and a scroll screen attracts a viewer's attention.

[0003] Examples of this display method include scrolling the news and weather forecast on a display board hung on the outer wall of a building, and scrolling display of the next arriving station name on a display board provided in a subway car. There is an example to make it.

[0004]

By the way, there is an attempt to realize such a display system on a liquid crystal display of a word processor. This means that, for example, when a word processor is provided as office equipment in an office, messages such as memos are scroll-displayed on a liquid crystal display of the word processor.

If such a function is provided, the liquid crystal display can be effectively used when the word processor is not used, which is convenient.

However, when the voltage values of the contrast control voltages are equal, the display screen is darker on the scroll screen than on the still screen. The reason is as follows. The liquid crystal display switches between transmitting and blocking light by controlling the voltage applied to each pixel. However, in the scroll display, since the display changes quickly, the time for applying a voltage to each pixel is extremely short. With this short application time, each pixel cannot sufficiently switch between transmitting and blocking light, so that the contrast of the liquid crystal display decreases. For this reason, when displaying a message after using the word processor on a still screen, the contrast control voltage must be adjusted each time, which is troublesome and troublesome.

An object of the present invention is to solve such a problem.

[0008]

In order to solve the above-mentioned problems, a message display method of a word processor according to the present invention comprises a selection means for inputting a document to be inputted as either a general document or a message document. Message document storage means for storing the message document input by the input device in the storage device, scroll means for scrolling the message document stored in the storage device on the liquid crystal display, and scrolling of the message document by the scroll means Voltage changing means for increasing the contrast control voltage of the liquid crystal display during display.

[0009]

According to the message display method of the word processor of the present invention, the message document input by the input device by the message document storage means is stored in the storage device.
Then, the message document stored in the storage device is scroll-displayed on the liquid crystal display by the scroll means. During such scroll display, the contrast control voltage applied to the liquid crystal display by the voltage changing means increases. For this reason, it is possible to prevent the display screen of the liquid crystal display from being darkened by the scroll display.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a block diagram showing the configuration of the word processor of the present embodiment. The word processor of the present embodiment includes a keyboard 110 for inputting a general document 121 and a message document 122, a memory 120 for storing the input document, a liquid crystal display 130 for displaying these documents, and a printer 140 for outputting the general document 121.
And a CPU 150 for controlling these devices. The liquid crystal display 130 performs switching between transmission and blocking of light and adjustment of contrast according to the applied contrast control voltage. The general document 121 refers to a general document such as a report or a plan,
The message document 122 is a message-only document such as a memo written only for scroll display on the liquid crystal display 130. General document 121
Is distinguished by pressing a predetermined selection key on the keyboard 110 before inputting a document from the keyboard 110. In other words, all the inputs after pointing to the general document 121 by pressing the selection key are stored in the memory 120 as the general document 121, and all the inputs after pointing to the message document 122 are stored in the memory 120 as the message document 122. Is done. In this way, by distinguishing the areas in the memory 120 between the general document 121 and the message document 122, it is clear that the subsequent processing targets are different. The document registered as the general document 121 can be output from the printer 140 after being updated as necessary. On the other hand, the document registered as the message document 122 is scrolled and displayed on the liquid crystal display 130 by the input of the message display start from the keyboard 110, and is not targeted for printer output.

Next, the processing contents of the message document 122 will be described with reference to the flowchart of FIG. First, a selection key on the keyboard 110 is depressed to instruct whether to handle the subsequent input as a general document 121 or a message document 122 (step 1).
0). If the general document 121 is specified (step 2
0) treats subsequent input from the keyboard 110 as a general document 121 and performs input / output processing of the general document 121 (step 30). If the user designates the message document 122 (step 20), the subsequent keyboard 110
Is handled as a message document 122 (step 40). After the input from the keyboard 110 is completed, the document is stored in the message document area in the memory 120 (step 50). Next, upon receiving a predetermined start key on the keyboard 110, scroll display of the message document 122 is started (step 6).
0). In performing the scroll display, first, the contrast control voltage applied to the liquid crystal display 130 is increased (step 70). This processing prevents scrolled characters from becoming too thin and difficult to see. Then, the message document 122 (step 80) read from the memory 120 under the high voltage is scroll-displayed (step 90). The end of the message display executed as described above can be performed by pressing any key on the keyboard 110. At the end, the contrast control voltage of the liquid crystal display 130 is restored (step 100).

The message document 1 which is a feature in the above processing
The processing for storing 22 in the memory 120 (message document storing means), the processing for changing the contrast control voltage applied to the liquid crystal display 130 (voltage changing means), and the processing for scrolling the message document (scrolling means) are all performed by the CPU 150. It is performed by control.
This control is performed based on an instruction of a control program (not shown) stored in the memory 120 or the CPU 15
0 is performed based on an instruction of a program incorporated in the program.

FIG. 3 shows an example in which a message is scroll-displayed on the liquid crystal display screen 210 of the simplified word processor 200. With such a small word processor 200, it does not hinder even if it is always kept on the desk in the office. And a general document 121 such as a document.
It would be very convenient if such a message could be displayed while it was not being used to create a message. In other words, when you leave a seat at a meeting or the like, if you can display a message such as "We are currently in a meeting. It will end at about 3 o'clock", you can tell at a glance when to return when someone with an errand comes. . In particular, the scrolling display makes it easy for people to get a lot of attention, compared to putting notes on the desk,
The probability that the person who asked will read the message is very high.

The present embodiment is effective when a person who asks during absence is required to leave a message for a person who is away at a meeting or the like. That is, in the present embodiment, since the processing is divided into the message document 122 and the general document 121, a third party cannot access the general document 121 as long as the mode is the message document 122 mode. Therefore, without worrying that the person who asked while absent might accidentally erase the general document 121 already stored in the memory 120, he / she can operate the word processor 200 and freely You can enter a message. As described above, in this embodiment, since the general document 121 and the message document 122 are managed separately, this management method plays a role of a kind of security.

Next, a display example of a message is shown in FIGS.
(D). This display example is an example in which a message such as “Meeting is currently underway. It is scheduled to end at 3 o'clock” is scrolled from right to left. Alternatively, scrolling may be performed from left to right, from top to bottom, or from bottom to top.

In this embodiment, the general document 121 and the message document 122 are managed in different areas.
The general document 121 and the message document 122 may be mixed and managed by using a flag or the like.

When the message document is scroll-displayed, the display may blink, or a buzzer sound or music may be played to draw attention.

[0019]

According to the message display method of the word processor of the present invention, the contrast control voltage applied to the liquid crystal display increases while the message is scroll-displayed on the liquid crystal display. For this reason, it is possible to prevent the display screen of the liquid crystal display from being darkened by the scroll display.
