DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character data input device.

[0002]

2. Description of the Related Art In general, in a facsimile apparatus, a memory for storing a set name of a facsimile apparatus is provided in order to display a set name of the facsimile apparatus on a display unit or a recording sheet of a facsimile apparatus of a communication destination. The department name is displayed by reading the department name data from the memory and transmitting it to the communication destination each time communication is performed. The method of inputting the department name data is as follows: (1) A method in which the registered characters and symbols are clearly specified in a predetermined format on a mark sheet and read by a facsimile machine for input. (2) group the input characters and assign the group to one key,
Pressing the key several times selects and confirms the characters in that group. (3) Various methods such as a method of assigning a code of several digits to input characters in advance and inputting code data with a numeric keypad have been adopted.

[0003]

The character input method (1) described above can be registered if only the mark sheet entry method is known without knowing the registration operation method.
There is a drawback that a mark sheet is always required at the time of registration, it takes time and effort to fill in many entries, and correction, addition and deletion are troublesome. Next, in the method (2), when selecting the last character in the group row, the number of key inputs increases, and guidance display of which group is selected, printing of a character group assigned to a key, and the like are required. . Furthermore, the method (3) is not affected by the restrictions of the display device, but requires a character code correspondence table. If the character data to be registered is not coded in advance, it takes a long time to input, and an instruction manual or the like is required. There is a disadvantage that it becomes necessary. As described above, the conventional character data input method has various drawbacks in spite of its advantages, and in particular, when the apparatus is reduced in size and price, restrictions are imposed on the number of keys, the number of digits of the display device, and the like. There is a demand for a simple input method.

[0004]

According to the present invention, there is provided a control circuit and data R which stores character data grouped by a predetermined number.
OM and the first of multiple digits where the specified character is displayed
A display comprising a display area and a second display area for displaying character data in the data ROM; a first cursor movement instruction key for instructing left and right movement of a first cursor displayed in the first display area; A selection key for selecting the group, and a second cursor movement instruction key for instructing left and right movement of a second cursor displayed in the second display area. If it is determined that there is a press, the character data of another group in the data ROM is switched and displayed in the second display area, and the character data at the second cursor position is displayed at the first cursor position of the first display area. The second cursor displayed in the second display area is moved and displayed in response to the operation of the second cursor movement instruction key, and the character data at the second cursor position is displayed in the second cursor area. When the operation of the first cursor movement instruction key for moving the first cursor by one digit is detected and switched to the first cursor position in the display area, the character data displayed at the first cursor position before the movement is detected. Is determined as an input character.

[0005]

Since the present invention is constructed as described above, in a facsimile apparatus provided with a display device having a small number of display digits, it is possible to perform input while further confirming characters by simple and simple key operations. Character input can be performed easily and accurately.

The value of the X counter (5D) counts up each time the "6" key is operated once, and counts down every time the "4" key is operated once, and is arranged in one line of the character data table. 1 when the count value is "1" among the 5 characters
Indicates the digit, and when "5", indicates the character data in the fifth digit. When the counter value reaches the upper or lower limit,
By the next further key operation, the lower limit value “1” or the upper limit value “5” is set in the X counter (5D). Next, the Y counter (5E) counts up each time the "8" key is operated once, and counts down every time the "2" key is operated once. "1" indicates the first line, and "11" indicates the last eleventh line. When the counter value has reached the upper limit or the lower limit, the lower limit value "1" or the upper limit value "11" is set in the Y counter (5E) by the next further key operation. Further, the Z counter (5F) counts up every time the "5" key is operated, and when the counter value is "1", the kana character data table is selected, when the counter value is "2", the alphabet character data table is selected, and "3" is selected. Use to select a numeric / symbol data table. When the counter value reaches the upper limit “3” or the lower limit “1”, the Z counter (5F) indicates the lower limit value “1” or the upper limit “ 3 "is set. In the initial state where no character input is performed, the initial value "1" is set in the counter of the data memory (5).

Here, the control operation of the control circuit (1) by the key operation of the ten key (13) in the own station name registration mode will be described.

First, when the "5" key is operated, the control circuit (1) which has detected the key signal in step (S2) proceeds to step (S11) and switches the character data table. That is, as shown in FIG. 7, "1" is set in the X and Y counters (5D) and (5E) in step (S71), and then the Z counter (5F) is incremented by 1 and the step (S73).
To determine whether the counter value is "4". Since the counter value is now "2", the control circuit (1) switches from the kana character data table (6A) to the alphabet character data table (6B). Next, step (S76)
Reads the data of the first row of the character data table (6B), writes it in the area (5B) of the data memory (5), and displays it in the area (8B) of the display (8). Subsequently, the control circuit (1) checks the value of the X counter (5D) in step (S77), and displays a cursor (8b) at the position of the area (8B) of the display (8) corresponding to the counter value. Now, the value of the X counter (5D) is "1", and the cursor (8b) is displayed at the position of the leftmost character. Subsequently, the control circuit (1) stores the data in the area (5B) of the data memory (5) corresponding to the character at the cursor position, that is, the value of the X counter (5D) in the area of the data memory (5) in step (S78). The data is written in the area (5A) of the data memory (5) corresponding to the value of the cursor counter (5C) of (5A), and simultaneously displayed in the area (8A) of the display (8). Now, the value of the cursor counter (5C) is "1", and the display is performed at the first digit. Next, when the "5" key is operated again, the value of the Z counter (5F) becomes "3". Therefore, the numeral / symbol table (6C) is selected, and when the "5" key is further operated, Since the value of the Z counter (5F) becomes "4", the control circuit (1) proceeds to step (S74) and sets "1" in the Z counter (5F). Therefore, the first kana character data table (6A) is selected. Thus, every time the “5” key is operated, the character data table (6
A) (6B) (6C) can be sequentially switched.

Next, when the "8" key is operated, the control circuit (1) which has detected the key signal in step (S3) proceeds to step (S12) and performs control to move down one line. That is, as shown in FIG. 8, the Y counter (5E) is incremented by 1 in step (S81), and then it is determined in step (S82) whether or not the counter value is the upper limit “12”. If the upper limit has not been reached, the process proceeds to step (S84), where the data of the row corresponding to the counter value is read out and written into the area (5B) of the data memory (5), thereby storing the data in the area (8B) of the display (8). Display. On the other hand, if the counter value has reached the upper limit, Y is determined in step (S83).
Since "1" is set in the counter (5E), the data of the first row is read and displayed.

On the other hand, when the "2" key is operated, the control circuit (1) detects the key signal in step (S4).
Goes to step (S13) to perform control to move up one line. That is, as shown in FIG. 9, step (S91)
Decrements the Y counter (5E) by one, and then proceeds to step (S9
In 2), it is determined whether or not the counter value is "0". When the counter value becomes "0", the control circuit (1) sets "11" in the Y counter (5E). Thus, when the first line is displayed, the operation of displaying the last line is repeated every time the "2" key is operated.

Next, when the "6" key is operated, the control circuit (1) detects the key signal in step (S5).
Goes to step (S14) to perform control to advance the selected character to the right by one digit. That is, as shown in FIG. 10, the X counter (5D) is incremented by 1 in step (S101), and then it is determined in step (S102) whether or not the counter value is "6". If the number has not reached “6”, the step (S1
04), a cursor (8b) is displayed at the position of the area (8B) of the display (8) corresponding to the counter value, and
The area (5) of the data memory (5) corresponding to the counter value
The data of B) is written in the area (5A) of the data memory (5).

On the other hand, if the counter value has reached "6", the control circuit (1) proceeds to step (S103) and sets "1" in the X counter (5D).
The cursor (8b) is displayed at the first digit of the area (8B). Thus, by operating the "6" key, the cursor (8
b) can be moved and displayed one digit at a time in the right direction.

Next, when the "4" key is operated, the control circuit (1) which detects the key signal in step (S6)
Goes to step (S15) to perform control to advance the selected character to the left by one digit. That is, as shown in FIG. 11, the X counter (5D) is decremented by 1 in step (S111), and it is determined in step (S112) whether or not the counter value is "0". If it is not "0", the process proceeds to step (S114) to display a cursor (8b) corresponding to the counter value.
On the other hand, if the counter value is "0", the control circuit (1) proceeds to step (S113) and sets "5" in the X counter (5D), so that the rightmost character in the area (8B) of the display (8) is displayed. Is displayed with a cursor (8b). Thus, by operating the "4" key, the cursor (8b) can be sequentially moved leftward and displayed one digit at a time.

Next, when the "0" key is operated, the control circuit (1) which detects the key signal in step (S7)
Proceeds to step (S16) and controls the insertion of space data. That is, as shown in FIG. 12, the control circuit (1)
Writes the space data in the storage position of the area (5A) of the data memory (5) corresponding to the value of the cursor counter (5C) in the step (S121), and then writes the space data in the step (S12).
In 2), the cursor counter (5C) is incremented by one, and the cursor (8a) is displayed at a position shifted by one digit to the right.

Next, when the "#" key is operated, the control circuit (1) which detects the key signal in step (S8)
Goes to step (S17) to perform control to move the cursor (8a) one digit to the right. That is, as shown in FIG. 13, the control circuit (1) increments the cursor counter (5C) by 1 in step (S131), and then proceeds to step (S13).
In step 2), a cursor (8a) is displayed at a position corresponding to the counter value. Therefore, each time the "#" key is operated, the cursor (8a) is moved right by one digit.

Next, when the "*" key is operated, the control circuit (1) which detects the key signal in step (S9)
Goes to step (S18) to control the cursor (8a) to move one digit to the left. That is, as shown in FIG. 14, the control circuit (1) decrements the cursor counter (5C) in step (S141), and then proceeds to step (S14).
In step 2), a cursor (8a) is displayed at a position corresponding to the counter value. Therefore, each time the "*" key is operated, the cursor (8a) is moved left by one digit.

Next, a specific input operation of the own station name will be described for a case where "Honsha IPD" is input as shown in FIG.

When the mode is set to the own station name registration mode by a predetermined key operation of the keyboard (7), the control circuit (1) which has detected the key signal causes the X, Y, Z counter (5D) (5E) ) (5F) and the cursor counter (5
Set the data of “1” to C). Therefore, the kana character data table (6A) is selected, and in the area (5B) of the data memory (5), the five characters of the first line, "Aio", are written, and the area (8) of the display (8) is displayed.
“Iueo” is displayed in B). Then, the cursor (8b) is displayed at the position of "A" of the first character. The character data at the position where the cursor (8b) is located is in the area (5).
Since it is stored at the first digit position of A), "A" is displayed at the first digit of the area (8A) of the display (8) (FIG. 16).
reference).

Here, since the first character to be entered now is "e", the "8" key of the ten keys is operated to advance the input line to line C. When the "8" key is operated five times, the Y counter (5E) becomes "6", and the data "hahifheho" of the corresponding c row is read from the kana character data table (6A), and the data in the data memory (5) is read. Area (5
B) and the area (8B) of the indicator (8)
(See FIG. 17). Then, when the "6" key is operated four times to select "e", the control circuit (1) counts in step (S101) of FIG. 10 and the X counter (5D) becomes "5". (8b) is moved and displayed at the position of "e". Therefore, at the same time as the data of "e" is written in the first digit of the area (5A) of the data memory (5), "e" is displayed in the first digit of the area (8A) of the display (8). . As a result, a desired character could be input in the first digit. When the "#" key was operated to change the input position, the control circuit (1) moved the cursor (8a) one digit to the right. Display at position. As a result, "e" of the input character data of the first digit is determined (see FIG. 18).

Next, in order to input the second digit character "n",
The "8" key is operated four times to read the data "Wan .." of the row of the character data table and write it to the area (5B) of the data memory (5). As a result, “Won ,.” is displayed in the area (8B) of the display (8) (see FIG. 19). At this time, the value of the X counter (5D) is "5",
Since the cursor (8b) is displayed at the right end, "n"
Operate the "4" key twice to select. As a result, the control circuit (1) decrements the X counter (5D) in step (S111) of FIG. 11 and sets the value of the X counter (5D) to "3", so that the cursor (8b) moves to the position "n". And the data of "n" is written in the second digit of the area (5A) of the data memory (5), so that "n" is stored in the second digit of the area (8A) of the display (8). Is displayed. As a result, the desired character can be input in the second digit, so the "#" key is operated to display the cursor (8a) at the input position of the third digit (see FIG. 20).

Thereafter, by appropriately performing key operations in the same manner as described above, "S" and "C" can be input. When the "0" key of the numeric keypad is operated because the space is entered after the input of "", the control circuit (1) causes the control circuit (1) to display the area of the data memory (5) indicated by the cursor (8a) in step (S121) of FIG. The space data is written at the position of (5A), and then the cursor counter (5C) is incremented by one at step (S122) to display the cursor (8a) at the position shifted by one digit to the right.

Then, since the next input is an alphabet, when the "5" key of the character data table switching key is operated, the control circuit (1) causes the control circuit (1) to execute Z (step S72) in FIG.
Since the counter (5F) is set to "2", the table is switched to the alphabet character data table (6B). And X,
Since the Y counters (5D) and (5E) are both set to "1" in step (S71), the first row of "ABCD"
Since the data of "E" is read and written in the area (5B) of the data memory (5), "ABCDE" is displayed in the area (8B) of the display (8), and the X counter (5) is displayed.
Since the value of D) is "1", the cursor (8b) is displayed at the position of "A". Since the character data "A" at the position where the cursor (8b) is displayed is written into the area (5A) of the data memory (5), the character data "A" is displayed at the cursor position in the area (8A) of the display (8). A "is displayed (FIG. 21).
reference). Since this is not the character desired to be input, the "8" key of the numeric keypad is operated to display "FGHIJ" as shown in FIG. By selecting "I", the data of "I" is written in the area (5A) of the data memory (5) and the display is performed in the area (8A) of the display (8) (see FIG. 23). . “P” and “D” can also be appropriately selected and input by operating a predetermined key on the numeric keypad (see FIG. 24).

When all the key inputs are completed, the own station name registration mode is terminated by a predetermined key operation of the keyboard (7). Thereafter, each time transmission is performed, the own station name data stored in the area (5A) of the data memory (5) is read out, transmitted to the receiving side, and recorded on the receiving recording paper as the source data. The number of character data tables, the number of display digits on the display, or the data storage capacity of the data memory can be set as appropriate.
