Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device equipped with erasing means for erasing printed characters.

[Conventional technology]

2. Description of the Related Art Conventionally, in this type of apparatus, printing apparatuses, such as electronic typewriter apparatuses, have been put into practical use and are equipped with correction means for correcting characters printed on a recording medium to blank using a correction tape or the like.

Next, conventional printing and erasing operations after printing will be explained with reference to FIGS. 9 and 10.

FIG. 9 is a flowchart illustrating a conventional printing control procedure. Note that (1) to (16) indicate each step.

When the power is turned on, this flow starts, initializes counters, etc. (1), and when the initialization process is completed,
The print mode is started and the printer waits for key input of print information (2) When the key input is made (3) the key input information is stored in the print memory (4).

Next, check the oldest key input stored in the print memory (5) to determine whether the stored one exists (6) If no, return to step (5) and wait for key input information. , if YES, determine whether the existing key information affects the carrier position of the printing section 7) If YES, execute printing etc. 8)
, store the output in the output memory (9). Next, determine whether the output is a character or a symbol (10); if NO, proceed to step (13) onwards;
If YES, determine whether it is to be used for overlapping characters 11), if YES, proceed to step (13) onwards.
If no, move the carrier one space in the printing direction (
12), The value in the position counter is increased or decreased by the amount that the carrier has ordered (13) @Then, the oldest stored value in the print memory is erased 14), Step (5)
Return to

On the other hand, if the judgment in step (7) is No, it is determined whether the input key is an erase key (15). If YES, the erase mode process shown in FIG. 10 is started; if it is NO, the input key is a code key. If the answer is YES, code mode processing is executed, and if the answer is NO, the command input by each key is executed and then the process returns to step (13).

FIG. 10 is a flowchart illustrating an example of an erase mode processing procedure in a conventional recording apparatus. Furthermore, (1)
~(4) shows each step.

Determine whether a character or symbol is stored in the output memory at the position where the carrier is stopped 1), YE
If it is S, erase the print corresponding to the position where the carrier is stopped 2), return to step (14) in Figure 9, and select No.
If so, move the carrier to the closest position where a character or symbol is stored in the output memory before the position where the carrier is stopped. 3) Decrease the value in the position counter by the amount the carrier has moved (4) Return to step (2).

FIG. 11 is a flowchart illustrating an example of a manual erase mode processing procedure in a conventional recording apparatus. Note that (1) to (18) indicate each step.

Waits for key input (1), and when key input is made (2)
) Key input information is stored in print memory (3)
.

Next, check the oldest one stored in the print memory (4) to determine whether the stored one exists or not (5), and if NO, return to step (4) and wait for key input. , If YES, determine whether the stored key information is a Leelock key (6) With this determination,
If No, check whether it is an erase key (7) If YES, delete the oldest item stored in the print memory.8) Then check the oldest item stored in the print memory. Check whether the object exists (9) and judge whether the stored object exists (10). If NO, return to step (9); if YES, the existing key information (key code) is checked. It is determined whether it is a character or a symbol (11). If NO, the process proceeds to step (13) and subsequent steps; if YES, the character or symbol is erased (12).

Next, the oldest one stored in the print memory is deleted 13) and the process returns to step (4).

On the other hand, if the determination in step (6) is YES, the code mode processing is output (14), the manual erase mode is canceled, and the process returns to step (13) shown in FIG.

On the other hand, if the determination in step (7) is No, it is determined whether or not it is a backtrace key.15), NO.

If so, execute the input key code processing16)
, the value in the position counter is increased or decreased by the amount of time the carrier has worked (F), and the process returns to step (Step 3).

On the other hand, if the determination in step (15) is YES, a buzzer sounds (18) and the process returns to step (13).

In this way, in conventional recording devices, when a character or symbol at a certain position is erased by transitioning from print mode to erase mode, after executing a specific erase operation once, it immediately returns to print mode. It is under control.

On the other hand, in manual erase mode, go to erase mode 8
If you want to erase a character or symbol in a row, perform two key operations: first input the erase key, then input the character or symbol you wish to erase. was.

[Problem to be solved by the invention]

However, especially when performing an automatic erasing operation by storing information to be erased while following the control procedure shown in Fig. 9 above, after executing a specific erasing operation, control is performed to immediately switch to print mode for 6 lines. , when the erasability of correction tape, etc. deteriorates due to deterioration of usage environmental conditions, or when slight deviations occur during 6th shift of paper even if usage environment conditions are good, it is not possible to completely erase with just a specific number of erasing operations. However, there was a problem in that the desired printed characters and symbols could not be erased in just the right amount.

In addition, even in the case of manual erasure in which the erased information is not memorized, it is necessary to operate multiple keys in order to repeatedly erase the same character or symbol at the same position after a specific erasure operation. However, as the number of characters to be erased increases, the operation becomes complicated and requires multiple key inputs for each character or symbol to be erased. There was a problem in that the recorded information correction processing efficiency was significantly reduced.

This invention has been made to solve the above problems, and when erasing characters or symbols in erase mode or manual erase mode, the characters or symbols are continuously erased during key input for one character erase request. To provide a recording device capable of completely erasing desired characters or symbols with a simple operation by continuing processing.

(Means for Solving the Problems) A recording device according to the present invention includes a first storage means for storing printed information inputted by a key, and a second storage means for storing information to be erased that is to be erased by an erasing means. It is provided with a storage means and an erasure control means for controlling the drive of the erasing means while comparing the information to be erased stored in the second storage means and the printed information stored in the first storage means. be.

FIG. 6 is a flowchart illustrating an example of the printing processing procedure according to the present invention. Note that (1) to (16) indicate each step. It is assumed that the character at the corrected position is stored in the output memory 14c.

First, when the power is turned on, the internal memory of the RAM 3 is initialized (1). That is, a print memory 14a, an output memory 14c, a position counter 14d.

"0" is set in the erasing memory 14b, corresponding to a state where information from the keyboard 13 etc. is not stored, and the position counter 14d is set at the position where the print head 15a is stopped.
This also corresponds to the state where the value is "0" (see FIG. 4(a)).

Next, the system waits for a key input from the keyboard 13 (2
) When a key is input from the keyboard 13 (3)
The key input is stored in the print memory 14a as shown in Fig. 4 (b).
), 30 characters are stored in the print memory 14a sequentially (for example, the capacity that can be stored in the print memory 14a is set to 30 characters), and the line < (4), it should be noted that the fourth
Figure (b) corresponds to a state in which rThehesd4 is entered by the key, and a code corresponding to that character is stored in the print memory 14a.

Next, the oldest code information input from the keyboard 13 and stored in the print memory 14a (position A in the figure)
6) If NO, return to step (5); if YES, the stored content will be transferred to the print head 15a.
7) If YES (for example, characters, symbols, spaces, etc. affect the printing position), print out the input information. (8).

Next, the code of the printed character or symbol is stored in the output memory 14c as shown in FIG. 4(b) (9
) Next, it is determined whether the output is printed text such as letters or symbols (10), and if No, step (13)
), and if YES, determine whether the type is to be used for overlapping characters (11), if YES, proceed to step (13) and later, and if NO, move the carrier one space in the printing direction. (12), and the value of the position counter 14d is increased or decreased by the amount of eight shifts of the carrier (13). Next, the oldest stored code in the print memory 14a whose output has been completed is erased (14), and the process returns to step (5).

On the other hand, if the judgment in step (7) is NO, it is determined from the key code whether the input key is the erase key 13b (15). If YES, the erase mode process shown in FIG. 7 is executed; if NO, the erase mode process shown in FIG. 16), YES.
If so, the program shifts to the code mode, and if NO, the commands input by each key are executed and the process returns to step (14).

As a result, as shown in FIG. 4(b), the codes corresponding to the key input order are stored in the print memory 14a, and the code stored at position A in the figure is transferred to step (6).
, After passing through the judgments in (7) and being output, each data is shifted one position to the left in the figure, and the next data at position A is judged in the same way.

In this way, what is sequentially output is stored in the output memory 14.
At the same time, the value in the position counter 14d also advances. At this time, if the amount to be stored in the output memory 14c is set in advance to, for example, 300 characters, then that amount of data can be stored.

Next, an explanation will be given of the erase mode processing when it is determined in step (15) that the key is the erase key 13b.

FIG. 7 is a flowchart illustrating an example of the erase mode processing procedure according to the present invention. In addition, (1) to (17)
indicates each step.

When the mode shifts to the erase mode, the memory in the output memory 14c at the position where the carrier, that is, the print head 15a is stopped, is checked to determine whether a character or symbol is stored at that position.1) If YES, the carrier is Erase the characters or symbols on the paper at the stopped position with tape 15
(2) The code of the erased character or symbol is stored in the erase memory 14b (3) Then, the data in the output memory 14C at the erased position is changed to one space data. (See (c)) (4) The oldest data stored in the print memory 14a whose output has been completed is erased (5).

As a result, as shown in FIG. 4(b), for example, rTh
When I entered "e hesd" and determined that I had entered "S" by mistake, I pressed the back's space key - 13.
Press d twice to return the carrier position to the 6th column position, and then press the erase key 13b to erase the printed characters.
Corresponding to the operation of erasing "s", by step (3),
The erasure memory 14b stores the code data "14" of the character "s", and the erased position, that is, the 6th
The value in the output memory 14C corresponding to the th column position is changed to data "AO" of one space.

Next, information is input from the keyboard 13 and the oldest one stored in the print memory 14a is checked (6).
7)
If No, the process returns to step (6) and waits for key input.

On the other hand, if the determination in step (7) is YES, compare the oldest code stored in the print memory 14a with the code stored in the erase memory 14b.
), determine whether the comparison results are the same9) YES
If so, proceed to step (15), erase the same character or symbol at the erased position, and then proceed to step (15).
Return to 5).

Therefore, it is possible to repeat the erasing process by simply pressing the key of the character you want to erase until the content stored in the print memory 14a differs from the content stored in the erasing memory 14b. Become.

On the other hand, if the determination in step (9) is NO, it is determined whether the input code affects the printing position (10), and if YES, the character at the position erased in step (2) is determined. Or print the symbol data memory 14
Change to the oldest stored data in a (11
).

Next, output the changed code data (1
2) Return to step (10) shown in FIG.

On the other hand, if the determination in step (10) is No, it is determined whether the input code is an erase command13), and YE
If S, return to step (1); if No, determine whether the key from the keyboard 13 is the code key 13c (14); if YES, execute the code mode; if NO
If so, execute each key-input command and proceed to step (5).
Return to

On the other hand, if the judgment in (1) is No, the carrier is moved to the nearest position where a character or symbol is stored in the output memory 14c before the position where the carrier is stopped (16). position counter 14d
17) and return to step (2).

As a result, "T" is output as shown in FIG. 5(a).
After sufficiently erasing the "S" in "he heSd", when the character "a" is inputted from the keyboard 13 as shown in FIG. ' is memorized. If the code "01" stored in the position A of the print memory 14a is different from the code stored in the erase memory 14b,
Proceeding to step (10), the code data in the output memory 14c at the erased position is changed to code "01". Then, the character "S" corresponding to the changed code data "01" is printed on the paper, and the print mode is returned to. 6, the carrier is moved by one space in the printing direction, the position counter 14d is incremented by 1, and the print memory 14 is incremented by 1.
The code "01" at position A in a is erased, and a series of printing and correction operations are completed. At this time, erase memory 14
The data b is changed to new data whenever new data is input.

Next, another embodiment of the present invention will be described with reference to FIG.

FIG. 8 is a flowchart showing an example of a manual erasing mode processing procedure in a recording head according to another embodiment of the present invention. Note that (1) to (28) indicate each step. Further, the manual erasure mode is an erasure mode when the character at the position to be corrected is not stored in the normal output memory 14C.

When the manual erase mode is started, the values in the erase memory 14b are initialized (1). Next, the system waits for a key input from the keyboard 13 (2). When a key is input from the keyboard 13 (3), the key input codes are sequentially stored in the print memory 14a (4).

Next, it is checked whether there is anything inputted from the keyboard 13 and stored in the print memory 14a (5), and it is determined whether or not there is any stored information 6).
N.

If so, return to step (5), wait for key input, and press Y.
If YES, it is determined whether the key-input information affects the print position, such as characters, symbols, spaces, etc. 7) If YES, a request is made to cancel the manual erase mode, that is, the release lock key 13a is pressed. 8) If YES, the manual erase mode is terminated and control is transferred to step (10) and subsequent steps shown in FIG.

On the other hand, if the determination in step (8) is No, it is determined whether the oldest stored code in the print memory 14a is the code corresponding to the backtrace key 13e9) If YES, step (28) Proceed to
After notifying the user using a buzzer or the like that the key input cannot be executed at this stage, step (1) shown in Figure 8 is executed.
7) Transfer control to subsequent steps.

On the other hand, if the determination in step (9) is No, the storage contents in the erasing memory 14b are checked (10) and it is determined whether the stored contents are characters or symbols 11). 12), if YES, step (18)
If the answer is No, check the oldest one stored in the print memory 14a (13) to determine whether the stored content is a character or symbol (14), and if the answer is No, go to step (23) or later. Go back, and if YES, erase the memorized characters or symbols on the printing paper 15)
, the information of the erased characters or symbols is stored in the erasure memory 14b (16), the oldest one stored in the print memory 14a is erased 17), and the process returns to step (5).

On the other hand, if YES in step (11), the oldest stored item in the print memory 14a is checked again (18), and whether the oldest item stored in the print memory 14a is a character or a symbol. Please decide 1
9), if No, proceed to step (23) and onwards, and select YES.
If so, compare the oldest code stored in the print memory 14a with the code stored in the erase memory 14b20), and determine whether the comparison results are the same21).
, if No, proceed to step (23) onwards; if YES (if you want to erase again the character or symbol that was erased - degree), erase the character or symbol that was erased - degree n times (2
2) The control is canceled after step (17) shown in FIG.

Therefore, until the user recognizes that the erased character or symbol has been erased, the user can simply input the erased character or symbol using the keypad, and the user can freely repeat the same character or symbol as many times as necessary until the user determines that it is different in step (21). Erasure of the same character or symbol at a position can be performed.

On the other hand, if the determination in step (19) is NO, the oldest information stored in the print memory 14a is outputted (23), and the outputted information is stored in the erase memory 14b (24).

Next, if the carrier has moved, the value in the position counter 14d is increased or decreased by the amount of movement (25).
Control is terminated after step (17) shown in the figure.
