Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] When data that cannot be displayed at one time on a display unit with a limited number of display digits is stored in memory, the data of the upper digit is displayed first and automatically after a certain time. Switch to lower digit display and display all digits.

[Industrial application field]

 The present invention relates to a display control device for a telephone.

[Conventional technology]

LCD contents read from memory in car phones
When displaying on a display such as (liquid crystal), if the number of digits n of the display is smaller than the number of digits m of the memory, a part of the memory contents may not be displayed. For example, since the maximum number of digits for domestic calls is 10 including the area code, the number of digits on the display is n =
It is generally set to 10. However, in the case of international calls, the country code is added, so the maximum number of memory digits is m = 16. In such a case, conventionally,
Since only 10 digits (or the lower 10 digits) can be displayed, there is the inconvenience that the remaining 6 digits cannot be confirmed.

[Problems to be solved by the invention]

The present invention avoids the above-mentioned inconvenience by displaying the contents of the memory separately.

[Means for solving problems]

The present invention relates to a display control device for a telephone, which displays telephone number data composed of numeric data input by a key on a display unit, and first display means for displaying the numeric data input by a key in the order of input, and the key input. Counting means for counting the number of digits of the digitized data, station number data discriminating means for discriminating whether or not the station number data of the telephone number data is a specific station number, and the discriminating result in response to the station number data discriminating means. When it is determined that the station number data of the telephone number data is a specific station number, the digit number changing means for changing the count value of the counting means by a predetermined number, and the count value of the counting means are the number of digits that can be displayed on the display (n ), And the digit number (m) of the telephone number data in response to the digit number determining means. Upon reaching the n), first switches the display of the numerical data displayed on said display device to display the remaining low-order (n) after a predetermined time 2
And a display means.

FIG. 1 shows an example of a display system to which the present invention can be applied.
Is an n-digit display, 20 is an m-digit (m> n) memory, and 30 is a microcomputer which converts the data stored in the memory 20 into, for example, seven-segment display data and gives it to the display 10. FIG. 3 is an explanatory diagram of the memory 20, and display control is realized by a program of the microcomputer 30.

[Action]

FIG. 2 shows a display example in which the number of digits that can be stored in the memory 20 is m = 16 and the maximum number of digits that can be displayed on the display 10 is n = 10. (A) shows the upper digits and (b) shows the lower 10 digits. It is a normal display. When there is a display request, the computer 30 checks the number of display data digits in the memory 20, and if it is n digits or more, only the normal display of (b) is performed. However, when the number of display data digits exceeds n digits, the upper digit display of (a) is performed first, and after a certain time (for example, 2 seconds), the normal display of (b) (lower n digits).
Switch to. Figure 2 shows a 16-digit telephone number 012345-678-901.
In this example, -2345 is divided into (a) and (b) and displayed.

At that time, considering that the length of the telephone number changes depending on the station number, by changing the count value (display data digit number) of the counter that counts the length of the telephone number data at a specific station number by a predetermined value, The number of characters displayed in the upper digit (a) is changed to prevent the display from being switched in the middle of the lower digit.

〔Example〕

As shown in FIG. 3, the memory for storing the display data of m digits is sequentially addressed from the lowest digit HYJ + 1 to the highest digit HYJ + m. The address from the lowest digit HYJ + 1 to the nth digit is HYJ + n, and this is the normal display target. And from address HYJ + n + 1 to HYJ +
Up to m are displayed in the upper digits.

FIG. 4 is a flow chart showing the principle of the present invention for this memory. In step S1, it is determined whether or not there is a display request. Taking the speed dial mode as an example, there is a display request when a memory recall key (generally also serving as a dial key) is pressed. At this time, the display request flag is cleared (step S2), and then it is checked whether or not there is data at the address HYJ + n (step S3). If there is not, nothing is registered and the process branches to. If there is, the HYJ-F1 flag is set and the display timer is set in step S4. HYJ-F1 is a flag indicating that there is display data at the addresses HYJ + 1 to HYJ + n, and the display timer is a timer for counting the time limit (for example, 8 seconds) of normal display.

Next, in step S5, it is checked whether or not there is display data at the address HYJ + n + 1. If not, the process branches to, but if there is, the process branches to and the HYJ-F2 flag is set in step S6, and the upper display timer is set. HYJ-F2 is address HYJ +
It is a flag that indicates that there is display data in n + 1 to HYJ + m, and the upper display timer is a timer that counts the time limit (for example, 2 seconds) for displaying the upper digit. This HYJ
If the -F2 flag is set, the upper digit is first displayed (steps S7 and S8). Then, when the upper display timer is up, the HYJ-F2 flag is cleared (steps S9 to S1.
1) Go to the normal display in step S12. Then, when the display timer is up, the HYJ-F1 flag is cleared, and all the displays are cleared, then another process is performed, and the process returns to the start via (steps S13 to S15).

The above is the case where there is display data in the upper digit of the memory, but if this is not the case, go to step S7
The normal display of S16 is performed, and the process returns to the start through steps S9, S17, S13. If there is no display request, step
The group passing through S1 and passing through steps S9, S17, and S15 is circulated. If there is no display data even if there is a display request, the process proceeds from step S3, and returns to the start via steps S9, S17, S5.

However, the telephone number may differ in length depending on the station number, and in the example of FIG. 4, there is a disadvantage that the display is switched in the middle of the last four digits of the telephone number.

Therefore, the present invention solves such a problem in the following embodiment. In the present embodiment, an example of display control in which the visibility of the display during normal dial operation is also improved will be shown.

5 (A), (B), (C) and (D) are flow charts showing the control of this embodiment.
Performed by 30. First, the counter C is set to 0 (step S20). Next, it waits for key input (step S21). Then, it is determined whether or not the key input is a number (step S22), and if it is a number, the counter C is incremented (step S23: C = C + 1), and step S
24. If the number is not a number, a process corresponding to the key input is performed, for example, if the start key is input, a calling process is performed (step
(S25, S26), if the end key, the end call process is performed (steps S27, S28), and if other key input, the process corresponding to the key input is performed (step S29), FIG. 4 (A) In step S1, the display control described above is also performed. If the input is a number, it is determined what number the input is (step S24: C = 2 is determined), and the second input (C =
If it is 2), it is judged whether the input number is "3" or "6" (step S30), and the flag RS is set according to the result (steps S31, S32: the input number is " If "3" or "6", RS = 1; otherwise, RS =
Set to 0). Then, enter the entered number on the display 2
It is displayed at the digit (step S33) and waits for key input again. If the input number is not the second input, 3
It is determined whether or not it is the third input (step S40), and the third input and the second input is "3" or "6".
If so (determined at step S41: RS = 1), the display is shifted to the right by 1 and then the third input is displayed at the next digit, that is, at the fourth digit. As a result, the number of digits of the displayed numerical data is increased substantially by one. If it is the third input and the second input is not "3" or "6" (step S4)
1: Judgment by RS = 0) The display is not shifted and the third input is 3
It is displayed in the digit (step S43). If the input is not the second or third, the input numbers are sequentially displayed on the display (step S52), but after the eleventh input, the display is shifted to the left by one digit and then the input number is entered. Is displayed in the lowest digit (steps S51, S52).

The display control in this embodiment is performed in Tokyo (03) and Osaka (0
This is to improve the visibility of the display that occurs because the total number of dialed telephone numbers in 6) is one digit less than in other areas. For example, dialing "06-123-4567" in Fig. 6 ( When you dial "078-123-4567", the display will be as shown in A), and the display will be as shown in Fig. 6 (B). The final dialed number will always be displayed at the bottom of the display, so check the dial. Etc. will be easier.

〔The invention's effect〕

As described above, according to the present invention, since the data having the number of digits larger than the number of digits of the display can be displayed separately, there is no possibility that some data is not displayed and the visibility is good. Also,
Since the display digits are automatically switched, there is also an advantage that a switching operation and a key for the switching operation are not required.

Further, since the number of digits for dividing the telephone number data is determined according to the area code of the telephone number data, it is possible to prevent a problem that the display is switched in the middle of the final dial number or the like.
