The present invention provides an input means for inputting memo information to be printed over a plurality of lines, a storage means for storing the memo information inputted by the input means, and the memo information stored in the storage means. The present invention relates to a memo printing device having a printing means for sequentially printing information while executing a predetermined change action, and in particular, for checking memo information to be printed line by line stored in the storage means. This was developed with the aim of obtaining a memo printing device that can perform means, an information storage means for storing the memo information and line feed information inputted by the information input means, and an information storage means for storing the memo information and line feed information input by the information input means; a printing means that sequentially prints while executing a change action every time the printing is performed, and an indication that the number of display output digits is the same as or larger than the number of print output digits of the above printing means; and display control means for sequentially displaying the memo information stored in the information storage means line by line on the display means based on the detection of the line break information. The present invention provides a printing device. 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 operations such as arithmetic 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, simply execute one-shot printing using the print key (PRT) on the keyboard.
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. 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. IMA: 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 display routine shown in FIG.
As shown in , 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
(ΔY) 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 sequentially displayed line by line) For example, "TO MR.TANAKA TELL CALL FROM
ABC CORP.'', the contents of the input memory IM and the display on the display 8 will be as shown in Figures 1 and 4, respectively, when the input is completed. It's summery. In this state, if you operate the up scroll key (ⓓ), after resetting the display digit counter DCC,
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 determination result is N (NO), DPA is decreased by "1" and it is determined whether the content at that position 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 → n ₉
Then, DPA is further decreased by 1, and at _n10 , it is determined whether the content at that position is a return code. The result is N, so proceed to n ₁₁ , increase the display digit counter DCC by "1", and then
At _n12 , it is determined whether the content of the DCC has become larger than the number of display digits of the display body. 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 display information exists after the currently executed display in the memory IM, the downward arrow symbol "〓" is displayed on the display 8 as shown in FIG. displayed on the right edge of 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 operated 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

During the repeated execution of the loop of [formula], the 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 will be as shown in FIG. 6. 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 when it is confirmed that there are no errors, the print key (PRT) is operated. This results in n ₂ →n ₃ →
The process proceeds as 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. As described above, according to the present invention, it is possible to obtain an extremely useful memo printing device that allows memo information to be confirmed line by line prior to printing.
