As shown in FIG. 4, the conventional wireless mobile terminal includes a receiving unit 1, a transmitting unit 2, a control unit 3, a display memory 4, and a display device 5. FIG. 4 is a configuration block diagram of a conventional wireless mobile terminal. In addition, in the case of a mobile phone or the like, the entire configuration has an apparatus for transmitting and receiving voice in addition to this, but here, only the screen display will be described.

The operation of each section of the wireless mobile terminal will be specifically described below. The receiving unit 1 receives message data and outputs it to the control unit 3. Transmission section 2
Receives the message data from the control unit 3, modulates it, and transmits it.

The control unit 3 receives the message data from the receiving unit 1, temporarily stores it in an internal memory (not shown), converts the message data into display data according to an instruction, and displays it in the display device 5. It is to be displayed.

Specifically, the control unit 3 includes a display memory 4
The image of the bitmap corresponding to the message data is drawn. For example, when the message data is a character string, the control unit 3 copies a preset bitmap of each character to the display memory 4. The control unit 3 also outputs message data input by the user according to an instruction to the transmission unit 2.

The display memory 4 is such that each pixel of the display device 5 corresponds to a bit of a fixed length (1 bit in the figure).

The display device 5 displays the content of the display memory 4 as it is as an image. Specifically, the display device 5 scans the display memory 4 and turns on the pixel when the bit of the display memory 4 corresponding to the pixel is "1", and turns off the pixel when the bit is "0". It is a thing. The operation of displaying characters can be easily realized by using the lighting / extinguishing operation of this pixel, and the technology thereof is well known, so that the description thereof will be omitted.

Next, the control operation of the display device of the conventional wireless portable terminal will be described. Here, specifically, when the display device 5 has a width capable of displaying, for example, 6 characters, 1
1-character message data "KEITAIDENWA"
The process when the is received will be described.

The receiving unit 1 uses the message data "KEITA
"IDENWA" is received and output to the control unit 3. Then, the control unit 3 tries to copy the bitmap corresponding to the character string of the message data to the display memory 4,
Since the display width of the display device 5 is up to 6 characters, "KEI
Copy up to TAI and avoid copying the remaining "DENWA".

The display device 5 displays "KEITA
The character "I" is displayed. Then, the user sees this and infers the original message data.

Further, in the conventional wireless portable terminal, when a specific operation is performed while "KEITAI" is displayed on the display device 5, the control section 3 displays the remaining "DENWA" in the display memory 4. There is also a device which is adapted to be displayed on the display device 5 after being copied on the display.

However, also in this case, for example, when the message is "Imasuguden Wakudaisai", it is customary to treat the dakuten or the like as one character. Therefore, "Imasugute" is displayed first, The display after that will be "", and it will take some thinking to understand the message data. Here, ""
Indicates the dakuten.

[0018]

Embodiments of the present invention will be described with reference to the drawings. The wireless mobile terminal (this terminal) according to the present invention enables the user to immediately understand the message data even if the message data is long by scrolling the screen.

This device will be described with reference to FIG. FIG.
It is a block diagram of a wireless portable terminal according to an embodiment of the present invention. This terminal, as shown in FIG.
The transmission unit 2, the control unit 3 ', the display memory 4, the display device 5, and the scroll unit 6 are provided. The scroll unit 6 further includes a scroll timer 61, a scroll control device 62, and a scroll unit. And the device 63.

Since the receiving unit 1, the transmitting unit 2, the display memory 4, and the display device 5 are the same as those of the conventional one,
Although the description thereof is omitted, in order to simplify the following description, the contents of the display memory 4 corresponding to the collection of dots of one row of the display device 5 is referred to as “line”, and one column of the display device 5 is referred to. The contents of the display memory 4 corresponding to a set of minute dots will be referred to as a "column".

Assuming that the display device 5 has a display area of 60 × 25 dots, a line means, for example, a line in FIG.
Indicates a group of 25 areas (0,0) to (24,0) in the display memory 4 shown in FIG.
It refers to 60 discrete areas from (24,0) to (24,59). FIG. 2 is an explanatory diagram showing the contents of the memory of the display memory 4.

The control unit 3'performs almost the same operation as the conventional control unit 3, but has an internal memory (not shown) for temporarily storing the message data input from the receiving unit 1. It is different from the conventional one in that it has it, and in response to a scroll instruction from the user, it outputs a scroll control signal to the scroll portion 6 and performs redrawing necessary for scrolling.

Specifically, the control section 3'receives an input of message data from the receiving section 1 and stores it in an internal memory. Further, the control section 3 ′ outputs a scroll control signal to the scroll section 6 in response to a scroll instruction from the user.

For example, when the user gives an instruction to scroll the screen downward to the control section 3 ', the control section 3'outputs a scroll control signal for shifting the line of the display memory 4 downward to the scroll section 6. To do.

Further, the control section 3'receives, from the scroll section 6, a signal for specifying the column or line of the display memory 4 to be drawn again as a drawing signal, and based on the message data stored in the internal memory, It is for drawing columns or lines.

That is, for example, when scrolling down, the contents of the actual addresses (physical addresses) on the screen are (0,58) to (24,58) are (0,59) to
It is copied to (24,59) and further (0,57) to (2
The contents of (4, 57) are copied to (0, 58) to (24, 28), and similarly, the contents of (0, 1) to (24, 1) are (0, 2) to (24, 2). ), (0,0) ~
The contents of (24,0) will be copied to (0,1) to (24,1).

Therefore, since new image data is not stored in the lines (0,0) to (24,0), the image data corresponding to that line is stored in the memory inside the control unit 3 '. It will be read and drawn (redrawn) on the line. The control unit 3'performs this redrawing.

Here, the column or line is after shifting. That is, since the contents of the display memory 4 correspond to a part of the internal memory of the control unit 3 ', the address (logical address) corresponding to the display memory 4 on the internal memory of the control unit 3'. Changes with each scroll, and the column or line here corresponds to the changed logical address.

For example, as shown in FIG. 3, initially, the logical address corresponding to the physical address (0,0) is (10
If one dot is scrolled downward, assuming that it is (0,100), the logical address corresponding to the physical address (0,0) becomes (100,99). Therefore, in this case, the control unit 3'uses physical addresses (0, 0) to (5
When the contents up to 9,0) are drawn again, the contents of (100,99) to (159,99) are copied with the logical address. FIG. 3 is an explanatory diagram showing a correspondence relationship between the contents of the memory of the control unit 3 ′ and the contents of the display memory 4.

The scroll unit 6 receives the scroll direction as a scroll control signal, shifts the contents of the display memory 4, and uses as a drawing signal a signal for specifying a line or a column which needs to be drawn again by the shift. It is output to the control unit 3 '.

To specifically explain each part that realizes the scroll part 6, the scroll timer 61 receives a scroll control signal from the control part 3 ', counts time, and times out in order to determine the scroll interval. A signal is output to the scroll control device 62. Specifically, a fixed time preset by the input of the scroll control signal is counted, and when the count is completed, a time-out signal is output to the scroll control device 62. The process of counting the fixed time again and the process of outputting the time-out signal are repeated.

The time counted by the scroll timer 61 may be changed depending on the time from when the user starts to receive a scroll instruction. That is, the scroll timer 61 counts the time from when the user starts receiving the scroll instruction, lengthens the scrolling interval until a specific time, and shortens the scrolling interval after that. It may be. By doing so, scrolling can be smoothly started.

The scroll control device 62 receives a scroll control signal instructing the scroll direction from the control section 3'and a timeout signal from the scroll timer 61, and outputs a scroll signal to the scroll device 63. It is a thing.

For example, the scroll control device 62 receives a scroll control signal for instructing scrolling downward from the control section 3 ', and also receives a time-out signal from the scroll timer 61 to cause the scroll device 63 to move down. Outputs a scroll signal for instructing 1-dot scrolling.

The scroll device 63 receives a scroll signal from the scroll control device 62 and shifts the image data of the line or column to the display memory 4.

For example, the scroll device 63 receives the input of the scroll signal for instructing to scroll down, rejects the contents of the physical address (0, 59), and outputs (0,
58) is copied to (0,59), (0,57) is copied to (0,58), and the image data of the line is thus copied to the corresponding portion of the line below. Make copies one after another.

Further, the scroll device 63 outputs to the control section 3'a signal for specifying a column or a line of the display memory 4 which needs to be drawn again due to scrolling, as a drawing signal. In the example of scrolling down, the line (0, 0) is the line that needs to be redrawn.

Next, the operation of this terminal will be explained, especially the operation when this terminal receives the message data of "Imagedden Wakudai". First, this terminal
The display device 5 operates in the same manner as in the conventional case and displays "Imasute".

Then, the user gives an instruction to scroll to the left in order to see the latter half of the message. Then, the control unit 3'receives this instruction, and receives the instruction.
2 outputs a scroll control signal for instructing to scroll left.

Then, at the timing when the scroll timer 61 times out, the scroll control device 62 outputs to the scroll device 63 a scroll signal instructing to scroll to the left. Then, the scroll device 63 that receives this scroll signal performs a process of shifting the column of the display memory 4 to the left, and also causes the control unit 3'to draw the rightmost column that needs redrawing. Is output.

The display unit 5 displays "Imasute".
“A” gradually disappears from the left, and instead, “″” gradually appears from the right end, and eventually “Masugude” is displayed. Here, if the user continues to give an instruction to scroll further to the left, the contents of the display device 5 will scroll further to the left, becoming "Sugden" and then "Guddenwa".

If the user is looking at the screen while instructing to scroll to the left, the message data of "Imasugden Wakudasai" will be scrolled dot by dot. Therefore, the message should be read as if it were a telop. You can

It is also possible to scroll diagonally by scrolling vertically as well as horizontally. Further, in the present embodiment, scrolling is performed for each dot, but a plurality of dots may be scrolled at once.

Further, this terminal may not only scroll-display the message data but also scroll-display the functions of the terminal body such as the calendar. This can be realized if the control unit 3'has a known method of displaying a calendar or the like.

According to this terminal, since a long message is smoothly scrolled and displayed like a telop, it is possible to display the message so that the user can immediately understand it.

[0046]

According to the invention described in claim 1, since the wireless portable terminal scrolls the contents of the display by the bit map, even a long message can be displayed by the scroll display so that the user can immediately understand. There is.

According to the second aspect of the present invention, the control unit outputs a scroll instruction signal to the scroll unit to start scrolling, and the scroll unit shifts the contents of the display memory in accordance with the scroll operation. This shift causes the control unit to draw in the area that needs to be redrawn in the display memory, and the shift and drawing are repeated to make it a wireless mobile terminal, so even long messages can be scrolled and displayed so that the user can immediately understand. There is an effect that can be.

According to the third aspect of the present invention, the scroll timer of the scroll section determines the scrolling interval by the signal of the scroll instruction from the control section, and the scroll control device indicates the scroll direction from the control section at the interval. A scroll signal is output, the scroll device shifts the contents of the column or line of the display memory by the scroll signal, and the shift unit outputs a drawing signal indicating a column or line that needs redrawing to the control unit, and the control unit Since the wireless mobile terminal according to claim 2 draws image data in a column or line required to be redrawn in the display memory by a drawing signal, even a long message can be displayed by scrolling so that the user can immediately understand. There is an effect that can be done.
