[Detailed description of the invention]

The present invention relates to a memo printing device that can easily confirm the digit position of memo information to be printed on a display and perform digit alignment before printing. Conventionally, in memo printing devices having a multi-digit display, when the number of displayed digits increases, it becomes difficult to grasp the number of digits of displayed information and the remaining number of digits that can be displayed.
This causes inconvenience during use. Furthermore, when the memo information to be printed is printed over multiple lines, it is not easy to align the digits of the memo information to be printed. For example, in a multi-digit display, it is not easy to display item name, unit price, quantity, amount, etc. as memo information to be printed by aligning the digits for each line. The present invention has been made in view of the above-mentioned conventional drawbacks, and particularly, digit position display information (hereinafter referred to as digit display information) indicating the digit position of multi-digit memo information to be printed.
It's called Mark. ) can be selectively displayed on the display where memo information is displayed. Hereinafter, the present invention will be explained in detail based on Examples. FIG. 1 is a block diagram showing a schematic configuration of a memo printing device according to an embodiment of the present invention. In the figure, 1 is the central processing unit (CPU), 2 is the read-only memory (ROM), 3 is the read/write memory (RAM), 4 is the print control unit (PCU), 5 is the printer, and 6 is the keyboard. , 7 is a display buffer, and 8 is a display body. The CPU 1 reads the key signal according to the procedure written in advance in the ROM 2, or
It performs various controls such as transferring the contents of the RAM 3 to the display buffer 7 and displaying them on the display 8, or transferring the contents of the RAM 3 to the PCU 4 and having them printed by the printing device 5. The ROM 2 stores procedures for reading, displaying, or marking key signals, and procedures for performing calculation operations in accordance with numerical values or formulas written in the RAM 3. RAM3 is an area for storing numerical values, characters, or formulas input using keys, as well as calculation results.
It consists of a storage area for various condition flags used in the processing process of the CPU 1, an area constituting a counter, etc. Note that the details of the flags, counters, etc. mentioned above will be described later. The PCU 4 generates a specific pattern of individual numbers or letters written in advance in the PCU using the numeric or character data transferred from the CPU 1, and controls the printing device 5 to print the specific pattern. The keyboard 6 is equipped with numeric keys 0 to 9, alphanumeric input keys A to Z, special symbol input keys, various function keys used for calculations, special keys for executing special operations described below, etc.
Strobe signal output from CPU1 and CPU1
It has a matrix configuration of common signals input to the In addition, the keyboard temporarily displays numbers, characters, or symbols entered using the above keys in sequence.
After storing data in RAM3, you can use the print key (PRT) on the keyboard to print all at once, and there is also a mode selection switch that allows you to switch between TYPE mode, which does not allow calculation processing, and COMP mode, which performs calculation processing. It is equipped. Also, regarding the keys on the keyboard, RTN is the return key, □↓, □↑ are the scroll keys,
SHIFT is a shift mode key, and the [〓〓] key is an operation unit that lights up or off the digit marker when pressed in shift mode, and is a simple alphanumeric key when pressed when not in shift mode. This is the key representing the letter P. These keys will be discussed further below. The display buffer 7 converts the numerical or character data transferred from the CPU 1 into a display signal suitable for the display 8 and outputs it, thereby displaying various numbers or characters on the display 8. FIG. 2 shows a part of the RAM 3. In the diagram
IMA, DPA and DCC indicate counters, UP,
DW and F indicate flags. Further, the input memory IM indicates an area where data inputted by keys in the TYPE mode is sequentially temporarily stored. The above counters and flags each have the following meanings. IAM: A counter that stores the cursor position in the input memory IM, and key-input data is written as a data code at the position specified by the counter. DPA: A counter that stores the display start position in the input memory IM, and displays data in the input memory IM after the position specified by the counter. DCC: A counter that stores the number of display digits, and is used to determine whether display information exceeds one line. UP: Set if display information exists before the currently executed display, and reset if not. DW: Set when there is display information after the currently executed display, and reset otherwise. F: Reset when the stored information immediately before the currently displayed information portion is a return code, otherwise set. FIG. 3 is a flowchart for explaining the operation of this embodiment. Step _n1 is initial setting before execution of the operation, and resets the counters and flags described above.
(Operation when inputting memo information) When a character, number or symbol key or return key (RTN) is operated, the character code, etc. or return code (RE) corresponding to the operated key is stored in the input memory IM. counter inside
It is written to the position specified by the contents of the IMA, and the IMA is counted up by "1" in preparation for the next input (n ₂ →n ₃ →n ₅ →n ₂₀ −n ₃₃ →n ₃₄ ).
Next, it is determined whether or not the information that has just been written is a return code, and if not, the display digit counter DCC is counted up by 1, and the content is greater than the display digit number on the display 8. Determine whether or not it has become large (n ₃₅ → n ₃₆ → n ₃₇ ). If no,
The program proceeds directly to the display routine, and the input contents up to that point are displayed (n ₁₈ ). When the operation key is the return key, the contents of the cursor position memory counter IMA are transferred to the display start position memory counter DPA, and the contents of the display start position memory counter DPA are updated (the current cursor position is the new display start position). After the display digit counter DCC is reset and the flag UP is set, the program proceeds to the display routine (n ₃₅ → n ₃₈ → n ₃₉ → n ₄₀ →
_n18 ). In addition, when it is detected that the contents of the display digit number counter DCC are larger than the number of display digits of the display object, the result of subtracting "1" from the contents of the cursor position memory counter IMA is added to the display start position memory counter. After being transferred to the DPA and updating the contents of the counter DPA (the position where the character code etc. was written immediately before is set as the new display start position), "1" is sent to the display digit counter DCC. input (unlike when the return key is operated, one character (symbol) has already been input when the display start position is updated) and the flag UP is set, and the display Proceed to routine (n ₃₇ →n ₄₁ →n ₄₂ →n ₄₀ →n ₁₈ ). Note that when the flag UP is set (that is, when display information exists before the display currently being executed in the input memory IM), the execution of the display routine
As shown in FIG. 4, an upward arrow symbol "〓" is displayed at the right end of the display 8. Taking three points in time while inputting memo information as an example, input memory at each point in time.
The contents of the IM and the display on the display 8 are shown in FIGS. 1 and 2, 3 and 4, and 5 and 6, respectively. 5 and 6 show the state immediately after the return key is operated. In addition, in the figure ▽X
(△X) is the position specified by the display start position memory counter DPA, that is, the display start position, and ▽Y (△Y)
indicates the position specified by the cursor position storage counter IMA, that is, the current cursor position. (Operation when memo information written to input memory IM is displayed line by line sequentially) For example, "TO MR. TANAKA TELL, CALL
If you input the memo information "FROM ABC CORP.", when the input is completed, the contents of the input memory IM and the display on the display 8 will be as shown in Figures 1 and 4, respectively. It's getting old. In this state, if you operate the up scroll key (〓〓), the display digit number counter DCC is reset, and then it is determined whether the display start position memory counter DPA is in the initial state (n ₂ - n ₃ →n ₅ →n ₆ →n ₇ →n ₈ ).
Since the judgment result is N (NO), set DPA to “1”.
down and determine whether the content at that location is a return code (n ₈ →n ₉ →n ₁₀ ). Since the judgment result is Y (YES), the state of flag F is checked (n ₁₀ → n ₁₃ ), but since flag F is in the reset state, after setting it at n ₁₄ , n ₈ →
Go to n ₉ , lower the DPA by 1, and go to n ₁₀ .
Determine whether the content at that location is a return code. The result is N, so proceed to n ₁₁ ,
The display digit number counter DCC is incremented by 1, and then, at _n12 , it is determined whether the contents of the DCC have become larger than the display digit number. Since the result is N, we return to n ₈ again and proceed further as n ₉ → n ₁₀ . From then on, until a return code is detected,

Repeat the loop in [Formula], and if a return code is detected, n ₁₀ →
Proceed to n ₁₃ and check the status of flag F again. This time, flag F is set, so n ₁₃ → n ₁₅
Then, at _n16 , the display start position memory counter DPA is raised to 1, and at _n17 , the flag DW is set, and the display routine is started.
Proceed to n ₁₈ . In the display routine, the data in the input memory IM after the position specified by DPA is displayed, but if there is a return code, the data after that is not displayed. Also, when flag DW is set (i.e. input
(When there is display information after the currently executed display in the memory IM), the downward arrow symbol "〓" will be displayed as shown in Fig. 4-2 by executing the display routine. It is displayed on the right end of 8. Therefore, the display at this time will be as shown in FIG. 6, 3. In addition, the above

During the repeated execution of the loop in [formula], the display digits counter
Also when it is detected that the content of the DCC is larger than the number of digits in the display body, steps n ₁₆ and n ₁₇ are executed and the process proceeds to display routine n ₁₈ . If you then operate the up scroll key, almost the same operation as above will be performed, but from now on,

During the repeated execution of the loop in [Formula], DPA=0 is detected, so the flag UP is reset at _n19 , the flag DW is set at _n17 , and then the display routine _n18 is executed.
Proceed to. Therefore, the display at this time is as shown in Figure 6 2.
It will be as shown below. Next, the operation when the down scroll key (〓〓) is pressed will be explained. If you operate the down scroll key while the display shown in Figure 6 2 is displayed, the number of displayed digits will be displayed.
After resetting the DCC, the display start position memory counter DPA is incremented by 1, and it is determined whether the content at that position is a return code (n ₂ →
n ₃ →n ₅ →n ₂₀ →n ₂₁ →n ₂₂ →n ₂₃ →n ₂₄ ). Judgment result is N
Therefore, proceed to n ₂₅ and display the number of digits counter DCC
is incremented by "1", and then in _n26 it is determined whether the contents of the DCC have become equal to the number of display digits of the display body. The result is N, so return to n ₂₃ again,
Execute "DPA+1" and proceed to n ₂₄ . onwards,
until a return code is detected.

The loop in [Formula] is repeatedly executed, and if a return code is detected, the display start position memory counter DPA is raised to "1" at _n27 .
After resetting the flag F at _n28 , setting the flag UP at _n29 and proceeding to _n30 . n ₃₀ ,
A determination is made as to whether there is any more display information after the information to be displayed next. In this case, since display information still exists, the process proceeds from _n30 to _n17 , and after the flag DW is set, the process proceeds to display routine _n18 . Therefore, the display at this time will be as shown in FIG. 63. In addition, the above

Repeating the loop of [formula], in the middle of the line, display digit counter DCC
When it is detected that the content of has become equal to the number of display digits of the display, the process proceeds from n ₂₆ → n ₃₂ , and the flag F is set.
After setting , execute the process from n ₂₉ onwards. The subsequent operation of the down scroll key performs almost the same operation as described above, but this time, since the judgment result at n ₃₀ is N, the process proceeds from n ₃₀ → n ₃₁ .
Reset flag DW and proceed to display routine _n18 . Therefore, the display at this time is as shown in FIG. 64. As is clear from the flowchart of FIG. 3, the up scroll key operation (or down scroll key operation) performed when the flag UP (or DW) is in the reset state is an invalid key operation. (Operation when printing memo information) Memo information is sequentially displayed line by line by operating the above-mentioned up scroll key or down scroll key, and if it is confirmed that there are no errors, press the print key (PRT). This results in n ₂ →n ₃ →n ₄
→n ₁ and printing is executed. FIG. 7 is a diagram showing a state in which memo information is printed on printing paper P. According to the present invention, the content to be printed in the TYPE mode (printer mode) can be entered using the keys, and the content can be displayed on the dot matrix display. Both printed and displayed digits are aligned to 20 digits, making it easy to understand. So the 8th
As shown in the figure, in order to make it easier to understand the number of displayed digits and the remaining number of displayable digits, you can see at a glance the number of dots displayed in addition to the dots displayed in the memo information display area every fifth digit. Digital markers are now displayed. As shown in FIGS. 1 and 2, the shape of the digit marker is made so that every n digit is different from every 2n digit, making it easier to understand. FIG. 8 shows an example of a display having digit markers (M ₁ to _{M 4} ) for indicating digit positions. In the figure, the character character display section consists of 20 digits, and 20 characters can be displayed at one time. Digit markers are provided at predetermined intervals, for example, every 5 digits, but as shown in Figure 9, the 5th and 15th digits are bar-shaped as shown in 1, and the 10th and 10th digit are bar-shaped.
The 20th digit is shaped like a keyhole. As shown in FIG. 10, the display electrode for the digit mark is displayed by a matrix of segment electrodes for the digit mark using one of the back plate signals (H ₇ ) for displaying characters etc. as a common signal. All the segment signals _S1 are common, and the digit marker is turned on in this manner, but depending on the instruction operation to turn on or off, an ON waveform or an OFF waveform is output as the segment signal _S1 signal. As described above, the present invention is characterized in that it provides a device in which the digit marker can be displayed as either lit or unlit (unlit) in the memo printing device described above, particularly by operating the operating section for displaying the digit position. In the display buffer 7 (see Fig. 1), there is a bit area (FD) corresponding to the segment area of the digit marker, and a bit area (FD) corresponding to the shift segment (shift display segment SS in Fig. 8). Has area (FS). FIG. 11 is a flowchart showing the operating procedure of a memo printing device having a digit position display function, which is a feature of the present invention. First, it is determined whether there is a key input (n ₁ , n ₂ ), and when a character key is input, the character code is input to the input buffer (in RAM 3) (n ₅ , n ₆ ). , if the SHIFT key is pressed, invert the flag FS (n ₄ , n ₇ →
n ₈ , n ₇ → n ₉ ). This flag FS represents the shift mode and corresponds to a predetermined area of the memory in the display buffer 7 as described above. That is, each time the SHIFT key is pressed, the shift symbol (SS) shown in Figure 8 is displayed.
lights up or goes out. If you press the "〓〓" key with FS set now, flag FS will be reset and flag FD will be inverted (n ₁₀ , n ₁₁ , n ₁₂ → n ₁₃ , n ₁₂ → n ₁₄ ).Flag As mentioned above, the FD also corresponds to a predetermined memory area in the display buffer.In other words, if you press the "〓〓" key in shift mode, the digit marker will turn off while it is still lit, and the digit marker will turn off. It will light up and the lighting (display) state will be reversed.Also, if the "〓〓" key is pressed not in shift mode (that is, when FS is in the reset state), the letter P will be displayed. When a key other than input, digit mark key shift key, or character key is pressed, processing is performed according to that key (n ₁₆ ).As explained above, according to the present invention, printing is Prior to printing, digit position information is displayed at predetermined intervals along with the memo information to be printed as necessary, making it possible to easily and reliably check the digit positions of characters, etc. at the same time as displaying the memo information, and printing on multiple lines. The alignment of each digit can be done easily and reliably by checking the digit position. Furthermore, if digit alignment for each line is not required, the display of digit position information can be turned off, and the digit position display does not bother users when inputting memos or the like.
