Abstract

PURPOSE:To make it possible to issue both of a label and a sheet without resetting a commodity name, by automatically changing over a commodity name for a label and that of a receipt corresponding to the conversion of a paper cassette. CONSTITUTION:When a printing key is pushed, CPU40 checks the cassette data in a working area EA5. In the case of a label cassette and a single commodity label, the single commodity label data in the working area EA5 is read and converted to a character pattern by using the character pattern in the area E4 to be written in a printing buffer area EA1. In the case of a sum total label, the sum total data in a sum total register area EA4-2 is converted to a character pattern and the content of the area EA1 is outputted to a printing part 47 and label printing is performed to be issued. In the case of a receipt cassette 56, the data in the sum total register area EA4-1 and that in the area EA-2 are converted to character patterns to be printed on receipt paper in the printing part 47. When the printing of all commodities written in a data register area EA3 is finished, a shop name, a data or the like are converted to character patterns to be printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a label/receipt printer capable of issuing both labels and receipts.

[Prior art]

Conventionally, a printer weighs the weight of a product, calculates the price of the product from this measurement result and the product's unit price (price per unit weight), and issues either a label or a receipt based on this calculation result. The device is widely used.

[Problems to be solved by the invention] By the way, the labeling method for labels attached to packed products is determined by the Food Sanitation Act, the Food Fair Competition Code, etc.
The product name characters printed on the label must be larger than a certain size. On the other hand, the product name characters printed on the receipt (usually using kana) are the general ECR (electronic register).
Because there is a plurality of product data to be printed and the width of the printing paper used, small characters are used. Based on this method, the above-mentioned printer also uses 9-sized characters. FIG. 46(a) shows an example of a label, and ←) shows an example of a receipt. As shown in this figure, the product name letter Ml on the label is considerably larger than the product name letter M2 on the receipt, which is usually used.
It is practically impossible to issue text receipts for labels or to issue labels with text for receipts. By the way, in conventional printer devices, only the product name characters of type LJA are set for one product, and therefore it is impossible to issue both a label and a receipt.

Therefore, an object of the present invention is to provide a label/receipt printer that can issue both labels and receipts.

Means for Solving Problem c] This invention makes it possible to issue both labels and receipts by appropriately selecting a cassette containing label paper or a cassette containing receipt paper and mounting it on the cassette mounting section. In a label/receipt printer that has been installed, a label product name code and a receipt product name code are stored in advance in memory for each product, and when a cassette containing label paper is installed, the label Printing is performed on label paper based on the product name code, and when receipt paper is built in and a next cassette is installed, printing is performed on the receipt paper based on the receipt product name code.

〔Example〕

FIG. 1 is a block diagram showing the electrical configuration when a label/register printer according to an embodiment of the present invention is incorporated into an electronic scale, and FIG. 2 is an external view thereof. First, the mechanical configuration will be explained.

In FIG. 2, reference numeral 1 is the main body of the printer, and on the front of this main body 1 there are a preset key 2a, a numeric keypad 2b,
A function key 20 or a ranal keyboard 2 is provided, a measuring pan 3 is provided on the top surface, and a display 4 is provided vertically at the rear of the main body. A cassette mounting section is provided on the right side of the main body 1, and a paper cassette 5 is mounted in this cassette mounting section. Here, the paper cassette 5 includes a label cassette (5a) that contains label paper, and a cassette (5a) that contains receipt paper and is used for cleaning sheets.
There are two types: 51).

FIG. 3(A) shows an example of the receipt paper 7 built into the receipt cassette 5h, which is a roll of thermal paper of a predetermined width. In addition, (b) and (c) of the same figure are views showing the vicinity of the end of the label paper 8 contained in the label cassette 5a, and thermal labels 10, 10, . . . are placed on the mount 9.
is pasted and wound into a roll. Here, between each label lO there are two detection sleeves) 11 and 11.
... is formed, and a terminal portion 12 on which nothing is pasted is provided behind the final label [0]. The detection strips 11)]l#... are provided in this manner because, when printing on the label 10, it is necessary to confirm the position of the label lO. Then, label paper 81r is passed between a light emitting element and a light receiving element of a transmission type photoelectric sensor, for example, and the detection is performed based on the resulting change in the output signal of the light receiving element.

The reason why the printing paper is loaded using a cassette is as follows.

In face-to-face sales using electronic scales, there are cases where cash is received and handed over at the time of weighing and selling, and in this case, sales are made on receipt paper with the name, unit price, and amount of each product printed on it. At the same time, it is necessary to print out the total amount and issue it.On the other hand, in large-scale stores such as supermarkets these days, money is sold by weight, and money is not handed over at the so-called checkout counter. Please make sure to pay for all items you purchase.

In such cases, other than the checkout counter, a label with the total price of the sold product printed on it is issued and attached to the package of the product, and the price is simply set. In view of the above circumstances, the present invention employs a cassette system so that both receipts and labels can be issued with one device.

FIG. 4 is a perspective view showing the structure of the label cassette 5a, and FIG. 5 is a diagram showing the internal structure of the same cassette 5a. The label cassette 5a is used for storing label paper 8 inside a shallow box body 15, and when the lid body 16 is opened, the label paper 8 can be stored. Here, the label paper 8 is fitted and attached to the rotating shaft 17, and the U-shaped guide plate 18,
Idle roller 19.20 then platen roller 21%
The label 10 is passed through the dispenser 22, where the label 10 and the backing paper 9 are separated, the label IO is discharged to the outside, and the backing paper 9 is taken up on a take-up reel 23. A prism housing section, which will be described later, is formed at the lower end of the guide plate 18, and a prism 24 is housed therein. Also, Kasetsu)
An opening 25 indicating that the cassette is a label cassette is formed on the rear surface of the cassette 5a, and a protection plate 26 is provided on the lower front surface.

Further, on the outer side of the lower surface of the cassette 5a, as shown in FIG.
7 and a ratio gear 28 which are fitted onto the shaft of the winding wheel 23, and when the cassette 5a is mounted on the balance body, these teeth 1127°28 are connected to the drive teeth IE2 on the scale body side.
9.30, and the platen roller 21 and take-up reel 23 are driven to rotate. In this case, the drive gear 29 is driven by a stepping motor 31 to drive the platen roller 21 at a constant speed, and the drive gear 30 is driven by a DC motor 32 for winding up the liner to rotationally drive the take-up 11-rule 23.

Next, FIG. 7 is a diagram showing the structure of the receipt cassette 5b. This cassette 5b is the above label cassette) 5
The difference from A is that there is no opening 25, idle roller 9, dispenser 22, and percentage take-off lever 23. The absence of the opening 25 indicates that this cassette 5b is a receipt cassette, and the absence of the dispenser 22 and take-up wheel 23 indicates that the cassette 5b is a receipt cassette.In the case of receipts, they are immediately ejected outside after printing, so the cassette 5b is a receipt cassette. This is because peeling off the label 10 and winding up the mount 9 are not necessary.

As a result, the receipt paper 7 fitted and attached to the rotating shaft 17 is sent to the outside via the guide plate 18, the idle roller 20, and the platen roller 21.

In this case, the platen roller 21 is driven to rotate in the same manner as in the case of the label cassette 5a described above, and conveys the receipt paper 7.

FIG. 8 is a plan sectional view showing the state in which the label cassette 5a is attached to the scale body. In this figure, 3
A thermal head 5 performs thermal printing on the label 10 while pressing the label paper 8 against the platen roller 21. The printed label IO is then peeled off by the dispenser 22 and discharged to the outside. Next, Sl, S
2 is a reflective photoelectric sensor, which determines whether the attached cassette is a receipt cassette 5b or a label cassette 5a.
This is to detect whether the As shown in this figure, when the label cassette 5a is attached, the photoelectric sensor 81 receives reflected light and turns on, but the light beam output from the photoelectric sensor S2 is projected inside from the opening 25. Since no reflection occurs, the photoelectric sensor S2 is turned off. On the other hand, in the case of the receipt cassette 5b, the opening 25
Since there is no sensor, the photoelectric sensor S2 is also turned on in the same way as 81.

Next, FIG. 9 is a sectional view taken along the line - in FIG. 8, and shows the configuration of the prism 24. As shown in FIG. This prism 24ti bends the light emitted from the light emitting element S3a of the photoelectric sensor S3 attached to the scale body side into a U-shape, and the label paper 819 passes through the receipt paper 7 and the next light is transmitted to the photoelectric sensor S3. It controls the light to reach the light receiving element 831). In this way, t light is received by the light receiving element 831) depending on the thickness and transmittance of the sheet passing through the guide plate 18.

Next, the operation of the apparatus with the above configuration will be explained.

[1] When issuing a label In this case, the staff first attaches the label cassette 5a shown in FIGS. 4 and 5 to the printer main body l. When the label cassette 5a is correctly attached to the main body l, the photoelectric sensor S1. On signal from S2C (Fig. 1, Fig. 8),
An off signal is output, and the printer interface 52 detects that the label cassette 5a is attached based on the output signals of these photoelectric sensors S1 and S2, and outputs the label cassette 5a. Cassette data indicating the cassette is output to pass line B. This cassette data is stored in the RAM 45 via the CPU 40.
is written in the working area EAS. Next, the clerk places the product on the weighing pan 3 and inputs the product number using the keyboard 2.

When a product is placed on the weighing pan 3, the weighing section 41 (FIG. 1) outputs weight data WD corresponding to the weight of the product. Also, when the product number is input, the CPU 40
RAM 45 PLU data area EA2 shown in 3 causes
, the PLU data C corresponding to the input product number (unit price, effective days, label printing product name, receipt printing product name) is read out and transferred to the working area EA5, and the weight data WD is transferred to the same working area EA.
Transfer to 5. Next, the CPU 40 uses the working area EA.
The price of the product is calculated based on the weight data WD and unit price data in 5, and the calculated price data is stored in working area EA5. Next, the CPU 40 outputs the weight data WD, unit price data, and price data in the working area EA5 to the display section 43. As a result, the display 4
(Fig. 2) displays each of the above data.

Here, when issuing a single item label (label for b items), the staff member presses the button key on the keyboard 2.

On the other hand, when issuing a total label C (a label on which the total price of multiple products is printed), the staff member presses the plus key on the keyboard 2.

When this plus key is pressed, working area EA5
The PLU data, weight data WD, and price data in the RAM 45 are stored in the data register area EA3 (first
Figure 4) is transferred to the total register area EA.

(initial reset) is incremented, and the price data transferred from working area EA5 is added to data C (initial reset) in area EA4-2. , place the second product on the weighing pan 3, and input the product number. As a result, weight data and the like are displayed on the display 4 in the same way as in the case described above. Next, when the staff member presses the plus key, each data regarding the second product is stored in the data register area EAa, and next, in the case of data in area EA4-1 of total register area gA4, rl
J) is incremented, and the price data is added to the data in area EA4-2. Thereafter, similar processing is repeated. Then, the clerk presses the print key after operating the plus key for the last product.

The operation after the print key is pressed will be described below with reference to the flowchart shown in FIG. When the print key is pressed, the CPU 40 proceeds to step SPI and checks whether the aforementioned cassette data in the working area EA5 is cassette data indicating the label cassette 5a or not (cassette data indicating the receipt cassette 5b). . If the label cassette 5a is the next one, the process advances to step SP2. In step SP2, it is determined whether or not the plus key has been pressed8.If the plus key has not been pressed, the process proceeds to step SP3, where the single item label data is written to the print buffer area EAI. conduct. That is, the unit price data, valid days data, etc. and label printing product name data in the working area EAS are read out, the read 7t4 data is converted into a character pattern using the character pattern in the area E4 of the ROM 44, and this character pattern is used to print the label. Write in the print buffer 17a IAI with the same power distribution as the character arrangement in the case of .

On the other hand, if the judgment result in step SP2 is rYEsJ, C
If the plus key is pressed), proceed to step SP4 and print the total label data.

That is, the total data in the total register area EA4-2 is converted into a character pattern, and the total data in the print buffer area EAI is converted into a character pattern.
Write inside. In this case, the unit price, product name, etc. are not written.

Next, when proceeding to step SP5, the print buffer area IA
The contents of I are sequentially output to the printer section 47. As a result, label printing is performed in the printer section 47. For example, the label shown in FIG. 16 (a) is a single item label).
is automatically issued. Then, when label printing is completed, the label paper is fed and C step 5P6
), when the next 9° bell reaches the home position, i.e.
The photoelectric sensor 83 (Fig. 89) detects the label gap and at the 9th point C step 5P7), the process ends.

[2] When issuing a receipt In this case, the clerk first attaches the receipt cassette 5b shown in FIG. 7 to the main body l. When the receipt cassette 5b is attached to the main body l, the photoelectric sensor fs1. Both η of s2
Therefore, an on signal is output and supplied to the II interface 7 and 8 52. This allows the printer 7
Cassette data indicating a receipt cassette is output from the Ace 52, and the output cassette data is sent to the CPU 40.
The data is written into the working area II EA5 of the RAM 45 via the RAM 45. Next (: The staff member places the first product on the weighing pan 3 in the same way as when printing a total label, enters the product number, presses the plus key, and then weighs the second product @
3, enter the product number, press the plus key, repeat this process, and press the print key when the plus key operation for the item C (nth item) is completed. Note that the processing performed by the CPU 4Q in response to each of the above operations is the same as in the case of total label printing described above.

Next, when the print key is pressed, the process of the CPU 40 proceeds to step SPI in FIG. 15. In this case, the determination result at step SPI is "NO", and the process therefore proceeds to step SP8. In step SP8, each data in the total register areas EA4-1 and EA4-2 is converted into a character pattern, and the data in the print buffer area 7EA117'
Written to J. Next, when the process advances to step SP9, the contents of the print buffer area EAI are sequentially output to the printer section 47. As a result, the total number and total price are printed on the receipt paper.

Next, when proceeding to step 5 PIO, the n-th line monovalent data, receipt product name data, t1 data, and price data of the data register area Ij area EA3 shown in FIG. 14 are read out one after another and converted into a character pattern. 17
written into AgA1. Next, proceeding to step 5PII, the contents of the print buffer area EAL are sequentially output to the printer section 47, and thereby the price, product name, weight, and price of the nth product are printed on the receipt paper. .

Next, proceed to step 5P12, data register +1
It is determined whether printing of all products stored in EA3 has been completed. If the judgment result is rNOJ, the process returns to step 5 PIO, printing processing is performed for the (n-1)th product, and the above process is repeated thereafter. Then, the judgment result of step SP]2 is rYE
When sJ is reached, the process advances to step SP13. Step S
In step SP]3, the store name, date, etc. are converted into character patterns and written in the print buffer area EAI, and then in step SP]4, the contents of the buffer area EAI are printed and output to the printer section 47. SPI 5
Then, the receipt paper is tweeded by a predetermined amount. This completes the entire process. Note that the above receipt issuing operation is the same whether there is one product or a plurality of products. In accordance with Example 1 above, when printing a receipt, a configuration is adopted in which the total number of items and the total number are printed before the individual product data, and the receipt is issued using a general ECR. Although the order of the receipt and the printing are reversed, this is a configuration adopted in relation to the creation of label printing, and is not limited to this configuration.

Although the above-mentioned practical example is a case in which the label/receipt printer of the present invention is incorporated into an electronic scale, it may be configured separately from the electronic scale and electrically connected thereto. Well done,
It is clear that there is no need to use it in combination with an electronic scale when dealing only with fixed price products that are not weighing products.

〔Effect of the invention〕

As explained above, according to this invention, J+! Paper cassette conversion 1: Correspondingly, the label product name code and the receipt product name code are automatically switched, and as a result, it is not necessary to reset the product name code when replacing the cassette.
