Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer. For example, in product sales data processing devices such as electronic cash registers and PO3 (point of sales) terminals, it can be used as a printer that prints and issues registered product names and unit prices on receipts.

[Prior Art 1] For example, a product sales data processing device such as an electronic cash register or a PO8 terminal is equipped with a printer that prints and issues the name and unit price of registered products on a receipt.

Conventionally, with this type of printer, each time a product is registered, the product name and unit price are printed on a single line on the receipt, and after all products have been registered, the total amount, deposit amount, and change amount are printed. Each is printed on one line and published. Also, if you want to correct a line that has already been printed by mistake,
After opening the printer cover, the receipt is turned over and a correction mark such as r=-m- is printed on the correction line.

[Problem to be solved by the invention] However, in the conventional correction work, after opening the printer cover, the receipt must be reversed to match the corrected line or printing position, which takes time. Not only that, but it was a hassle.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a printer that eliminates these conventional drawbacks and allows correction work to be performed easily and quickly.

[Means for Solving the Problems] Therefore, in the present invention, there are provided a printing means, a feeding means for feeding paper to the printing means, and a paper sending side of the printing means that is movable back and forth in the feeding direction of the paper. A correction stamp that can stamp a correction stamp on the paper is provided, and Wr.
a first storage means for storing a print line of data currently printed on a sheet of paper by the I-printing means; a second storage means for storing a corrected line of data already printed on the sheet of paper by the printing means; A correction stamp is moved in the feeding direction of the paper so that the correction stamp corresponds to the correction line of the paper from the printed line stored in the first storage means and the correction line stored in the second storage means. The apparatus is characterized by comprising a control means for moving the apparatus.

[Function 1] When the corrected line is stored in the second storage means, the correction stamp and the corrected line on the paper are obtained from the printed line stored in the first storage means and the corrected line stored in the second storage means. In contrast, since the correction stamp is affixed after being moved in the feeding direction of the paper, it is possible to automatically affix the correction stamp to the corrected line. Therefore, correction work can be performed easily and quickly.

Department keys 52 and subtotal keys 53 from “01” to “08”
, a deposit/account key 54, and a correction key 55.

In the RAM 14, in addition to product data files storing product names, unit prices, etc. corresponding to product codes, there is also a printed data table 6m shown in FIG. 4, and a print line area 62 as a first storage means. and a correctable area 63 as a second storage means. In the printed data table 61, the printed lines and product codes to be printed on the receipt 35 by the printing means 38 are written in order. In the print line area 62, the print line currently being printed by the printing means 38 is updated and stored. The correctability area 63 stores the correctability of the correction stamp 45 to be stamped.

The CPU 11 executes the normal processing of the product sales data processing device according to the program stored in the ROM 13, and when the correction key 55 is pressed, the fifth
Execute the process in the flowchart shown in the figure. Here, c
puti and ROM 13, the print line area 6
The correction stamp 45 is moved in the feeding direction of the receipt 35 so that the correction stamp 45 corresponds to the correction properties of the receipt 35 based on the print line stored in the print line stored in the correction property area 63 and the correction property stored in the correction property area 63. After that, a control means is configured to perform a stamping operation.

Next, the operation of this embodiment will be explained with reference to the flowchart shown in FIG.

When the product code of a product is entered on the keyboard 22, the product name and unit price corresponding to the product code are successively displayed from the product data file, and are printed in one line on the receipt 35 by the printer 25, as well as the print line at that time. and the product code are written into the printed data table 61.

Now, while registering the product in this way, if you do not want to correct the already registered data, that is, which line data printed on the receipt 35, enter the same product code and then Press the correction key 55.

Then, the CPU II proceeds with the process according to the flowchart in FIG. Step (hereinafter abbreviated as ST)
) Check whether the product code has been entered in step 1, and if the product code has been entered, proceed to step ST2.
Then, it is checked whether the input product code exists in the printed data table 61. If there is no product code, it will be treated as an error.

If there is a product code, the process advances to ST3, and after transferring the print line of that product code, that is, the correctability, to the correctability area 63, the S
Proceeding to T4, it is checked whether the correctability is greater than or equal to the value obtained by subtracting 3 from the print line in the print line area 62. Then, it is checked whether the corrected line≧printed line-3.

If the correctability is (printed line - 3) or higher, that is, if the correctability is between the printed line and the Baum position position HP of the correction stamp 45, proceed to ST5 + 3 - (printed line - Correctability)) The receipt 35 is fed by rotation of the platen 32.

Next, the process proceeds to ST6, where the correction stamp 45 is moved to the Baume position HP, and then the process proceeds to ST7, where the correction stamp 45 is lowered by the solenoid 44. In other words,
Activate the stamp operation.

In addition, in ST4, if the correctability is not greater than (print line - 3), that is, if the correctability is on the sending side of the receipt 35 with respect to the home position position HP of the correction stamp 45, proceed to ST8 and print the correction stamp 45. (home position position) I P, then proceed to ST9 (Print line - Correctability - 3) After moving the character correction stamp 45 to the left in Fig. 1, proceed to ST7 and print the correction stamp 45. It is lowered by the solenoid 44. In other words, it performs a stamping operation.

For example, as shown in FIG. 6, if the current print line is the fifth line, the home position HP of the correction stamp 45 is the lotus corresponding to the second line of the receipt 35. Here, if the fourth line is not corrected, if the same product code as that line is input, "4" is transferred to the corrected line area 63. Here, since 4≧5 (print lines) - 3 = 2, after the receipt 35 is fed for (3 to (5 - 4) + = 2 lines), the correction stamp 45 prints "== is in the 4th line. is stamped on top.

Also, if you want to correct the first line, enter the same product code as that line, and "1" will be transferred to the correction line area 63. Therefore, after the correction stamp 45 is moved by one line to the left in FIG. 1, the correction stamp 45 makes r==
=-1 is stamped on the first line 6 Therefore, according to this embodiment, the stamp mechanism 41 having the correction stamp 45 that can freely move back and forth in the feeding direction of the receipt 35 is provided on the paper sending side of the printing means 38. By moving the correction stamp 45 and feeding the receipt 35, the correction stamp 45 and the correction line are automatically paired and the correction stamp 45 is lowered, so there is no need to reverse the receipt as in the past. Therefore, the correction work can be performed easily and quickly.

In the above embodiment, the distance from the home position HP of the correction stamp 45 to the printed line of the printing means 38 is three lines, but if the distance can be reduced to one line, correction can be made simply by moving the correction stamp 45. The stamp 45 can be made to correspond to the corrected line.

Further, in the above embodiment, the same product code as the product code of the row that is not to be corrected is input, but the correctability may be manually determined and stored in the correction row area 63.

Further, in the above embodiments, an example in which the present invention is applied to a printer of a product sales data processing device has been described, but the printer of the present invention is not limited to these, and can be applied to other printers.
