Since the printing mechanism PM is not directly related to the present invention, it will be briefly described. The thermal head 13 (see FIG. 1) having a predetermined number of heating elements arranged in the vertical direction has a predetermined width made of a transparent film. While supplying the printing tape 5 having (for example, 12 mm) and the ink ribbon,
The heating elements are energized, characters and symbols are printed on the printing tape 5 by a plurality of dot rows, and then the double-sided tape is joined to the printing tape 5 and the tape is fed from the character frame 2 to the outside. To be done. The printing tape 5, the ink ribbon, the double-sided tape, etc. are integrally built in a rectangular tape storage cassette. For details of the printing mechanism PM, refer to Japanese Utility Model Laid-Open No. 1-85050.

Next, the control system of the tape printer 1 is shown in FIG.
The block diagram of FIG.

A keyboard 3, a display controller (LCDC) 23 having a display RAM for outputting display data to the LCD 22, a drive circuit 25 for driving the thermal head 13, and a tape feed motor 24. The printing mechanism PM including the drive circuit 26 is connected to the input / output interface 27 of the controller C, respectively.

The control device C includes a CPU 29 and this CPU
An input / output interface 27, a CGROM 30, a ROM 32, which are connected to 29 via a bus 28 such as a data bus.
And a RAM 40.

CGROM (pattern data memory) 30
For each of a large number of characters, the dot pattern data for display and printing is stored in the column corresponding to the code data. In the ROM 32, a display drive control program for controlling the LCDC 23 in correspondence with character codes and symbol codes of characters such as characters, numbers and symbols input from the keyboard 3, and data in the print buffer 43 are sequentially read to read the thermal head 13 and the like. Tape feed motor 24
A print drive control program for driving the printer, a control program for a display method peculiar to the present application, and the like are stored.

The RAM 40 includes a memory area for a text memory 41, a print format memory 42, a print buffer 43, a pointer memory 44, a flag memory 45, and a counter memory 46.

The text memory 41, which constitutes the storage means of the present invention, stores code data of characters and symbols input from the keyboard 3 as document data. The print format memory 42 stores a plurality of print format information such as set character size data, typeface data, and selected character decoration data. Print buffer 43
Stores dot pattern data for printing a plurality of characters and symbols that have been image-developed.

The pointer memory 44 stores position information of the text memory 41 designated by the relocate pointer RLCP, the cursor pointer CSLP, the display start pointer DSP and the display end pointer DEP which form the first character designating means of the present invention. To be done.

Each of these pointers will be described with reference to FIG. FIG. 3 shows an example in which dot pattern data corresponding to the document data in the text memory 41 is displayed on the LCD 22. In this figure, the portion outside the display area of 6 characters of the LCD 22 is the text memory 4 which cannot be displayed on the LCD 22.
1 shows a state in which all the document data in 1 are tentatively represented as dot patterns.

The relocate pointer RLCP indicates the end position of the code data stored in the text memory 41, for example, by the number of characters of the document data stored from the beginning of the text memory 41. The cursor pointer CSLP indicates the code data displayed at the cursor position, which is the second from the end of the display area of the LCD 22, by the number of characters. The display start pointer DSP is
The display start position of the code data stored in the text memory 41 is designated by the number of characters. The display end pointer DEP indicates the maximum value that the display start pointer DSP can indicate in the confirmation mode, and is set to a value obtained by subtracting 5 from the pointer value of the relocate pointer RLCP.

The flag memory 45 stores flag data of the scroll flag SF. Scroll flag S
F indicates that when the flag data is "0", the character is set to scroll one character at a time in the confirmation mode, and when the flag data is "1", there are six characters in the confirmation mode. Indicates that the setting to scroll by one is made.

The counter memory 46 stores a count value for counting a predetermined time.

Next, the control by the controller C of the tape printer 1 will be described with reference to the flow charts shown in FIGS.

When the power is turned on by operating the power key 3c, this control is started. First, each memory is cleared and the format code is stored at the head of the text memory 41. Further, each pointer value of the relocate pointer RLCP and cursor pointer CSLP is set to "1", the pointer value of the display start pointer DSP is set to "-3", and the flag data of the scroll flag SF is set to "0". Initial settings such as are executed (S1). When this initial setting is completed, “>” indicating the format code is displayed together with the cursor only on the fifth digit of the cursor position on the LCD 22.

Then, it is determined whether or not there is a key input from the keyboard 3 (S2). Wait until there is a key input (S2: NO), and if there is a key input (S2: YE
S), it is determined whether or not the input key is the character key 3a (S3).

In this tape printer 1, the print format such as the character size, the typeface, and the character decoration is set before the characters are input. Therefore, the size setting key or the format setting key is operated before the character key 3a is operated (S3 / S7: NO), and the data related to the print size such as the character size, the typeface, and the character modification corresponding to the operation is stored in the format memory. It is stored in 42 (S10). After that, the process returns to S2, and the key input is awaited.

When the character key 3a is operated (S2.S
3: YES), the code data corresponding to the operated character key 3a is stored next to the position of the text memory 41 designated by the pointer value of the cursor pointer CSLP (S).
4) The pointer values of the cursor pointer CSLP, the relocate pointer RLCP, and the display start pointer DSP are each incremented by 1 (S5). Then, the code data for 6 characters stored in the position on the text memory 41 designated by the pointer value of the display start pointer DSP to the value obtained by adding 5 to the pointer value is read and corresponds to the code data. The dot pattern is displayed from the first digit of the LCD 22 (S6).

For example, when the character key 3a of "A" is operated while ">" is displayed at the cursor position of the LCD 22, the code data of "A" is stored in the second digit of the text memory 41. , The pointer values of the cursor pointer CSLP and the relocate pointer RLCP become “2”, and the pointer value of the display start pointer DSP becomes “−2”. Then, the text memory 41 designated by the value "3" obtained by adding 5 to the pointer value "-2" of the display start pointer DSP
Characters corresponding to the code data of 6 characters stored in the upper position are displayed on the LCD 22.

However, there is no position designated by "-2" to "0" in the text memory 41, and the format code is stored at the position designated by "1" in the text memory 41. Further, since the code data of the character "A" is stored at the position designated by "2", nothing is displayed on the 1st to 3rd digits of the LCD 22 and 4
“>” Is displayed at the digit and “A” is displayed at the fifth digit which is the cursor position. Further, since no code data is stored in the position designated by "3", nothing is displayed on the sixth digit of the LCD 22.

When the confirmation key 3b is operated to confirm the input contents while the character key 3a is operated and a predetermined character string is input (S2: YES, S3: NO,
S7: YES), the confirmation mode process is executed.

When the confirmation mode process is executed, first, the scroll amount setting screen is displayed on the LCD 22 (S21). In this scroll amount setting screen, LCD2
2 is displayed as "1/2?" And the operator is given the number "1".
Prompt operation of key or "2" key.

Operation of the keyboard 3 is awaited while the scroll amount setting screen is displayed on the LCD 22 (S22: N
O), when the number "1" key is operated (S22, S2
3: YES), the flag data of the scroll flag SF is set to "0" (S24), and it is selected to display the input character string while scrolling character by character from the beginning to the end. Further, when the numeral “2” key is operated (S22: YES, S23: NO, S25:
YES), the flag data of the scroll flag SF is set to "1" (S26), and it is selected that the input character string is displayed while scrolling by 6 characters from the beginning to the end.

When a key other than the numeral "1" key or "2" key is operated (S22: YES, S25 / S2).
3: NO, the buzzer 20 sounds to notify that an unnecessary key has been operated (S27), and the key input is awaited again (S2).

After the processing of S24 or S26 is executed, the pointer value of the display start pointer DSP is set to "1" (S28), and the counter memory 46
A predetermined value "N" is set to the count value WT of the (S2
9) Similarly to S6, the code data for 6 characters stored in the position on the text memory 41 indicated by the pointer value of the display start pointer DSP plus 5 is read out. The dot pattern corresponding to the code data is displayed from the first digit of the LCD 22 (S30). Number "1" or "2"
Immediately after the key is operated, for example, as shown in FIG. 6A or FIG. 7A, 6 characters from the beginning of the input character string, that is, “> ABCDE” is displayed on the LCD 22.

During this display, it is judged whether or not the count value WT has become "0" (S31). If the count value WT is not "0", the count value WT is decremented by 1 (S32). Then, the process of S31 is executed again, and it is determined whether or not the count value WT has become “0”.

When the count value WT becomes "0" (S3
1: YES), it is determined whether or not the pointer value of the relocate pointer RLCP is larger than "6" (S33),
When the pointer value of the relocate pointer RLCP is "6" or less (S33: NO), the number of characters input is 6 or less, all the characters input in the process of S30 are displayed, and the operator inputs them. I can confirm all the characters. After that, this confirmation mode ends, and the processing of S9 shown in FIG. 4 is executed.

On the other hand, if the pointer value of the relocate pointer RLCP is larger than "6", it is not possible to display the entire input character string by only displaying the six characters from the beginning in 30. Therefore, the following processing is performed.

First, the display end pointer DEP
Is set to a value obtained by subtracting "5" from the pointer value of the relocate pointer RLCP (S34).
Then, it is determined whether or not the pointer value of the display start pointer DSP and the pointer value of the display end pointer DEP match (S35). If both pointers DSP and DEP do not match (S35: NO),
It is determined whether the flag data of the scroll flag SF is "0" (S36), and if the flag data of the scroll flag SF is "0" (S36: YES), that is, it is set to scroll by one character. If so, the pointer value of the display start pointer DSP is incremented by 1 (S37), and the processing from S29 onward is executed.

If the flag data of the scroll flag SF is "1" (S36: NO), that is, if scrolling by 6 characters is set, the pointer value of the display start pointer DSP is increased by 6 ( S38), it is determined whether the pointer value of the increased display start pointer DSP is larger than the pointer value of the display end pointer DEP calculated in S34 (S39), and the pointer of the increased display start pointer DSP. If the value is less than or equal to the pointer value of the display end pointer DEP (S3
9: NO), since there are seven or more undisplayed input characters, the processing of S29 and thereafter is executed.

The pointer value of the increased display start pointer DSP is the display end pointer DE.
When it becomes larger than the pointer value of P (S39: YE
S) Since the number of undisplayed input characters is 6 or less, the pointer value of the display end pointer DEP is set as the pointer value of the display start pointer DSP, and the processing from S29 onward is executed.

If the pointer value of the display end pointer DEP and the pointer value of the display start pointer DSP match (S35: YES), the confirmation mode ends and S9 shown in FIG. 4 is repeated. The process of is executed.

For example, by operating the character key 3a, "A"
When inputting up to "N", "J" to "N" are displayed in the first to fifth digits of the LCD 22 (S2, S).
3: YES, S4 to S6). In this state, the confirmation key 3b
Is operated (S2: YES, S3: NO, S7: YE
S), the state where the scroll amount setting screen is displayed (S
When the numeral "1" key is operated in step 21) (S23: Y
ES), as shown in FIG. 6A, from the beginning of the text memory 41 to the sixth character on the LCD 22, that is, “> AB
"CDE" is displayed for a predetermined time (S29 to S31). When the predetermined time has elapsed (S31: YES), the pointer value of the display start pointer DSP is incremented by 1 and becomes "2" (S37), so the character string displayed on the LCD 22 is scrolled leftward by one character. (S3
3 to S37), as shown in FIG.
"F" is displayed for a predetermined time (S29 to S31).

Thus, as shown in FIGS. 6 (a) to 6 (c), the input character string is scrolled leftward by one character every time a predetermined time elapses, as shown in FIG. 6 (d). like,
When "IJKLMN" is displayed, the pointer value of the display start pointer DSP and the pointer value of the display end pointer DEP match (S3).
5: YES), the confirmation mode ends.

When the numeral "2" key is operated in the state where the scroll amount setting screen is displayed (S21) (S25: YES), the LCD as shown in FIG. 7A is displayed.
22 is displayed up to the sixth character from the beginning of the text memory 41, that is, ">ABCDE" is displayed for a predetermined time (S29-
S31). When the predetermined time has elapsed (S31: YES), the pointer value of the display start pointer DSP is increased by 6 to become "7" (S37), and the character string displayed on the LCD 22 is scrolled leftward by one character. (S33 to S37), as shown in FIG.
“GHIJK” is displayed for a predetermined time (S29 to S3).
1).

After that, the display start pointer D
The pointer value of SP is increased by 6 to become "13", but since this pointer value becomes larger than the pointer value "10" of the display end pointer DEP calculated in S34 (S39: YES), the display start pointer The pointer value of the DSP is set to the pointer value “10” of the display end pointer DEP (S40), and “IJKLMN” is set to the LCD 22 as shown in FIG. 7C.
Is displayed for a predetermined time (S29 to S31). Then, after the elapse of a predetermined time (S31: YES), the pointer value of the display start pointer DSP and the pointer value of the display end pointer DEP match (S3).
5: YES), the confirmation mode ends.

When the confirmation mode ends, the pointer value of the cursor pointer CSLP is changed to the relocate pointer RLCP.
Is set to the pointer value of the display start pointer DSP and the pointer value of the display start pointer DSP is set to the relocate pointer R.
It is set to a value obtained by subtracting 4 from the LCP pointer value (S9). Then, six characters from the position of the text memory 41 designated by the pointer value of the set display start pointer DSP are displayed from the first digit of the LCD 22 (S6). By the processing of S9 and S6,
The display state of the LCD 22 returns to the state immediately before the operation of the confirmation key 3b. Therefore, character input work, edit work such as changing / adding / deleting characters at any position by operating the scroll keys, etc., printing work by printing the character string input on the printing tape 5 by operating the print key It becomes possible to execute processing such as.

The control device C executes the processes of S28 to S40 to form the designated position moving means of the present invention, and the control device C executes S6 or S30 to display control means of the present invention. Is configured.

As described above, in the tape printer according to the present embodiment, by operating the confirmation key 3b, the character string input to the LCD 22 is displayed with 6 characters from the beginning, and one character is displayed every time a predetermined time elapses. Since the displayed character string scrolls to the left by 6 characters or 6 characters at a time, you can check the input character string in order from the beginning by a simple operation of pressing the confirmation key, and the operator can confirm the input character string. This frees you from the hassle of repeatedly operating the scroll keys when doing.

If the scrolling amount is one character at a time, it will take time to confirm all the input character strings.
In this embodiment, since the scroll amount can be selected from two types or 6 characters, if the input character string is large, the scroll time can be selected to be 6 characters to shorten the confirmation time.

The present invention is not limited to the above-mentioned embodiment, but various kinds of restrictions can be applied within the scope of the invention.

For example, the number of digits displayed on the LCD 22 is not limited to six, and the scroll amount can be selected by one.
Although the number of characters is 6 or 6 characters, 1 to 6 characters or 1 to the maximum number of display digits may be arbitrarily selected.

In the above embodiment, when the confirmation key is operated, the scroll is repeated until all the character strings are displayed. However, a stop key is provided and the stop key is operated to stop the scrolling in the middle. It is also possible. When the stop key is operated, it is possible to return the display state to the display state at the time when the stop key is operated, or to return to the display state at the time when the confirmation key is operated,
Each operation such as input / edit / print can be performed from the time when the stop key is operated.

Further, in the above embodiment, the dedicated confirmation key 3b for setting the confirmation mode is provided.
The confirmation mode may be set by operating another key.

Further, the present invention can be applied to a device other than a tape printer, which stores a character string consisting of characters and symbols input by input means such as a typewriter or word processor in the storage means and displays it on the display means. Needless to say.
