Description

[Detailed Description of the Invention] The present invention relates to a method for visually displaying characters such as letters, numbers, and symbols in electronic devices such as computers, and more specifically, a display that can display more characters than display digits. Regarding the method.

Conventionally, when the number of characters to be displayed is greater than the number of display digits, the display contents are replaced by all digits or by sequentially shifting the characters to the next digit. Displaying a lot of information. The above-mentioned method of replacing the display contents in all digits has the advantage that the displayed characters do not shift and remain stationary, making it easier to see, but since the characters displayed in all digits are replaced at once, It cannot be said that it is easy to understand the continuation of the previously displayed display content and the subsequent display content. Furthermore, in the above-mentioned method of sequentially shifting and displaying characters,
A large amount of information can be displayed continuously,
Although this is convenient for understanding the context of information, it has the disadvantage that it is difficult to see because the character display shifts.

An object of the present invention is to provide a display method that makes the displayed characters as easy to read as possible and also makes it easier to understand the context of the displayed contents when the number of characters to be displayed is greater than the number of display digits. .

The present invention groups characters to be displayed, interposes a group display section for displaying separation between groups, and first displays all characters that can be displayed on all display digits at once, The display status is
Based on the first display step maintained for a predetermined time and the detection of the group display section, when a character forming part of a group is displayed at the rear of the display digit in the shift direction, the remaining last character of the group is displayed. A second display step in which the characters are continuously shifted and displayed until . This display method is characterized by including a third display step in which subsequent characters are displayed on all display digits at once and the display state is maintained for a predetermined period of time.

FIG. 1 is an electrical circuit diagram of one embodiment of the present invention. Characters to be displayed are input by a key input device 1, encoded by an encoder 2, and stored in a shift register 3.
The contents stored in the shift register 3 are transferred to the shift register 4 as described below. The contents stored in the shift register 4 are decoded by a decoder 5, and characters are displayed on a display 6.

Figure 2 shows the characters displayed by the display device shown in the first figure. According to the invention, these characters to be displayed are grouped and
In this embodiment, the characters are divided into a first group of characters "ABC...Z" and a second group of characters "Iun...". Between groups,
A group display section for displaying group divisions is interposed, and in this embodiment, the group display section is ",". The display 6 has a plurality of n digits,
It is assumed that the first group and the second group have character numbers m and l larger than this n digit. Each group may have some meaningful content, such as words or sentences. From the key input device 1, characters including the group display section "," are input.

The stored contents from the shift register 3 are transferred from the group display section detection circuit 7 to the data buffer 8 and
It is transferred to the shift register 4 via the AND gate 9. Shift register 4 has n-digit store cells. The store detection circuit 10 detects that the signal corresponding to the character to be displayed is stored in the last digit of the shift register 4, that is, the nth digit store cell. Store detection circuit 10
is the flip-flop 11 according to its detection output.
Reset. The flip-flop 11 is set by operating the display start key 12 to cause the display 6 to start displaying. The set output of flip-flop 11 is input to AND gate 9 via OR gate 13, and
Group display detection circuit 7 via OR gate 14
is input to input terminal E of. flipflop 1
The reset output of 1 is input to the input terminal U of the timer 15. A single pulse-like output from the output terminal W of the timer 15 is given to OR gates 13 and 14, and also passes through the OR gate 16 to the timer 1.
It is input to the other input terminal V of 5. The output from the output terminal of the group display section detection circuit 7 is applied to the OR gate 16 .

The group display section detection circuit 7 is activated from the flip-flop 11 by operating the display start key 12.
By the set output through the OR gate 14, that is, by the input of a pulse to the input terminal E at the beginning of the display, it is activated and causes the transfer of the store contents from the shift register 3 to the shift register 4. , then becomes activated by receiving a pulse at input terminal E, and performs the following two steps.
In cases (a) and (b), a single pulse is output from the output terminal F, and when the next pulse is input to the input terminal E, the n-digit data in the shift register 3 is Transferring the stored contents corresponding to the character to the shift register 4: (a) The stored contents corresponding to the n-digit character are transferred, and the nth digit is displayed in the group display section ","
If it is. (b) When the store contents corresponding to a single-digit character are transferred and the store contents are the group display section ",".

The timer 15 is in operation when the reset input from the flip-flop 11 is applied to the input terminal U, and when a time limit T has elapsed from the time when the reset input is received, and when another input terminal V is applied, the timer 15 is activated.
It has a function of outputting a single pulse from the output terminal W when a time limit T has elapsed since the pulse from the OR gate 16 was input.

The operation for displaying the character shown in FIG. 2 on the display body 6 will be explained with reference to FIG. 3. The character "ABC...YZ, Eye..." is input using the key input device 1, and then the display start key 12 is operated. As a result, flip-flop 11 is set and its set output is input to AND gate 9. Therefore, the contents stored in the shift register 3 are transferred to the shift register 4. When the signal is transferred to the nth digit store cell of shift register 4,
Store detection circuit 10 causes flip-flop 11 to remain reset. Thus the third
As shown in FIG. 1, at the beginning of the display operation, n
Digit characters "ABCD...N" are displayed on all digits of the display 6 at the same time. This display state is maintained for a time limit T after the timer 15 receives the reset output from the flip-flop 11.

Next, the output from timer 15 is OR gate 1
3 to AND gate 9 and OR
The signal is input from the gate 14 to the group display section detection circuit 7. The stored contents corresponding to the single digit character "O" of the shift register 3 are transferred to the shift register 4 via the group display section detection circuit 7, the data buffer 8 and the AND gate 9. In this way, the display state shown in FIG. 32 is obtained, and the displayed character is shifted by one digit in the shift direction (to the left in FIG. 3). Since the output from the timer 15 is also input to the input terminal V of the timer 15 via the OR gate 16, the display state in FIG. maintained for a period of time. Thereafter, similar operations are repeated, and the display states shown in FIGS. 3 and 3 are obtained every time limit T.

After the display state of FIG. 3 and 4 is achieved for a time T, the output from the timer 15 indicates that
Store contents corresponding to shift registers 3 to 4
will be forwarded to. The group display section detection circuit 7 detects this group display section "," and the timer 15
Outputs a pulse from output terminal F during the output duration from . Therefore, the display state shown in FIG. 3 is maintained for the time limit T determined by the timer 15.

In this way, when characters forming part of the first group are displayed at the rear of the display digits in the shift direction (right side in FIG. 3), for example, as shown in FIG.
~When in the state shown in FIG. 3 3, the character is set for the time limit T of the timer 15 until the last remaining character "Z" of the first group is displayed as shown in FIG. 3 4 or 3 5. The display is continuously shifted one digit at a time.

When the group display section detection circuit 7 moves from the display state of FIG. 3 4 to the display state of FIG. 3 5, the display state of FIG. 3 5 is changed by detecting the group display section ",". After a time limit of T,
By receiving a pulse output from timer 15, shift register 3 is activated during the duration of the pulse.
From then on, the stored contents corresponding to the subsequent n-digit characters are transferred to the shift register 4. In this way, the n-digit characters "Aiu...Kaki" are displayed all at once as shown in FIG.
It is maintained for a time limit T of 5.

In this way, the last character "Z" of the first group is displayed at the rear of the display digits of the display 6 in the shift direction, as shown in FIG. The digits are displayed all at once as shown in FIG. 3 and 6, and the display state is maintained for the time limit T of the timer 15.

Thereafter, as shown in FIG. 3, the characters are continuously shifted and displayed one digit at a time for each time limit T.

As shown in Figure 4, the characters to be displayed are divided into the first group of characters "ABCD...N" and the second group of characters "OPQR.", and between the groups there is a group display section ",".
is mediated, “ABC…N,”
Assume that up to n digits are equal to the displayed digits. At this time, by transferring the stored contents of the shift register 3 to the shift register 4, the group display section detection circuit 7 detects the group display section "," in the n-th digit, and as shown in FIG. After the display state is maintained for the time limit T of the timer 15, the contents stored in the shift register 3 corresponding to the subsequent less than n-digit character "OPQR." are transferred to the shift register 4. In this way, among the n digits displayed,
All digits of the display digit number equal to the number of the character "OPQR." are displayed at once as shown in FIG. 52.

As shown in FIG. 6, assume that at the beginning of the display, the number n of display digits includes not only the characters to be displayed but also the group display section ",". The character shown in FIG. 6 is stored in the shift register 3 along with the group display section "," using the key input device 1, and then the display start key 12 is operated. As a result, the flip-flop 11 is set, and the contents stored in the shift register 3 are transferred to the shift register 4 via the group display section detection circuit 7. In this way, the n-digit display body 6
``ABCD...M,N'' is displayed as shown in Fig. 71. When transferring the first n-digit store contents, the group display section detection circuit 7 detects only the n-th group display section "," as described above. Thereafter, the shift display is performed one digit at a time as shown in FIGS. 7-2 to 7-3. After the last character "R" of the first group is displayed at the rear of the display digits, subsequent characters are displayed simultaneously on all digits as shown in FIG. 74. After that, 1 as shown in Figure 7 5.
Shift display is performed digit by digit.

Although the group display section is "," in the above-described embodiment, it is not intended to be limited to this, and may be, for example, a blank space of one digit. In the embodiment described above, if the shift is performed one digit at a time, it is continuous at every time T, but
As another embodiment of the present invention, particularly in the case of dot display, the character shift display may be performed continuously without stopping.

As described above, according to the present invention, the characters to be displayed are divided into groups by the group display section, and at the beginning of the display, all the display digits are displayed at the same time, and the display state is maintained for a predetermined period of time. Next, continuous shift display is performed until the last character of the group is displayed at the rear of the display digit in the shift direction, and when the last character of the group is displayed at the rear of the display digit, all digits of the display digit are swapped. ,
Since the display is made for a predetermined period of time, by making each group a character with meaningful content such as a word or sentence, it becomes easier to grasp the display contents, and the display state is maintained for a predetermined period of time. Therefore, an easy-to-read display is performed. That is, according to the present invention, characters corresponding to the number of display effective digits are first displayed all at once, and then shifted and displayed in order. When the last character of the group is displayed, the characters corresponding to the number of display effective digits of the subsequent group are displayed all at once. Since the display is switched, it is possible to clearly recognize the division between each group, and the contents of the subsequent group can be read quickly.
