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 that can issue both labels and receipts.

[Prior art]

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

[Problem that the invention seeks to solve]

By the way, the method of labeling affixed to rejected products is determined by the Food Sanitation Act, the Food Fair Competition Code, etc., and the product name characters printed on the label are stipulated to be larger than a certain size. On the other hand, the product name characters printed on the receipt (usually kana are used)
In general ECRs (electronic registers), fairly small characters are used due to the need to print multiple pieces of product data and the width of the printing paper used. For this reason, the printers mentioned above also use characters of a similar size. FIG. 16A shows an example of a label, and FIG. 16B shows an example of a receipt. As shown in this figure, the product name character M1 on the label
is considerably larger than the product name character M2 of a receipt that is normally used, and therefore, it is practically impossible to issue a receipt with characters for a label or to issue a label with characters for a receipt. By the way, in conventional printer devices, only one type of product name character is set for one product, and for this reason, it has been 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 problems]

This invention provides a label/receipt printer that can issue both labels and receipts by appropriately selecting a cassette containing label paper or a cassette containing receipt paper and mounting it on a cassette loading section. A label product name code and a receipt product name code are stored in memory for each product, and when a cassette containing label paper is installed, the label paper is stored in memory based on the label product name code. When printing is performed and a cassette containing receipt paper 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/receipt 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 preset keys 2a,
A keyboard 2 consisting of a numeric keypad 2b and a function key 2c 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 1. Further, 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. There are two types of paper cassettes 5: a label cassette 5a containing label paper and a receipt cassette 5b containing receipt paper.

FIG. 3A shows an example of the receipt paper 7 contained in the receipt cassette 5b, which is a roll of thermal paper of a predetermined width. Also,
FIG. 4B shows the vicinity of the end of the label paper 8 contained in the label cassette 5a, in which heat-sensitive labels 10, 10, . . . are pasted onto a mount 9 and wound into a roll. Here, a detection slit 11 of approximately 2 mm is formed between each label 10, and a terminal end portion 12 on which nothing is pasted is provided at the rear of the final label 10. The detection slits 11, . . . are provided in this manner because, when printing on the label 10, it is necessary to confirm the position of the label 10. and,
This position detection is performed, for example, by passing the label paper 8 between a light emitting element and a light receiving element of a transmission type photoelectric sensor, and 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 money is exchanged at the time of weighing and selling, and in this case, the product name, unit price, and amount of each item sold are printed on the receipt paper, as well as the total amount. and issue it. On the other hand, in recent large-scale stores such as supermarkets, money is no longer transferred at the point of sale by weight, but payment for all purchased products is made at a so-called checkout counter. In such cases, other than checkout counters, 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 view showing the internal structure of the cassette 5a. The label cassette 5a has a shallow box body 1.
The label paper 8 is stored inside the lid body 1.
When 6 is opened, label paper 8 can be stored. Here, the label paper 8 is fitted and attached to the rotating shaft 17, passes through the U-shaped guide plate 18, idle rollers 19, 20, and then the platen roller 21,
It passes through a dispenser 22, where the label 10 and the backing paper 9 are separated, the label 10 is discharged to the outside, and the backing paper 9 is wound up on a take-up reel 23. A prism accommodating portion, which will be described later, is formed at the lower end of the guide plate 18, and the prism 24
is stored. Further, an opening 25 is formed on the rear surface of the cassette 5a to indicate that it is a cassette for labels, and a protection plate 26 is provided on the lower front surface.

Further, on the outside of the lower surface of the cassette 5a, as shown in FIG. 6, a gear 27 fitted to the shaft of the platen roller 21 and a gear 28 fitted to the shaft of the take-up reel 23 are disposed. When the cassette 5a is attached to the balance body, these gears 27, 2
8 meshes with the drive gears 29 and 30 on the scale main body side,
The platen roller 21 and take-up reel 23 are rotationally driven. In this case, the drive gear 29 is driven by the stepping motor 31 and the platen roller 29 is driven by the stepping motor 31.
1 is driven at a constant speed, the drive gear 30 is driven by a DC motor 32 for winding up the mount, and the winding reel 23
drive the rotation.

Next, FIG. 7 is a diagram showing the structure of the receipt cassette 5b. This cassette 5b differs from the label cassette 5a in that it does not have an opening 25, an idle roller 19, a dispenser 22, and a take-up reel 23. The reason why there is no opening 25 is because
This cassette 5b indicates that it is a receipt cassette, and the reason why there is no dispenser 22 and take-up reel 23 is because in the case of a receipt, it is ejected to the outside immediately after being printed. This is because winding is not necessary.

As a result, the receipt paper 7 fitted and attached to the rotating shaft 17 is moved to the guide plate 18 and the idle roller 2.
0, it is sent to the outside via 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 when the label cassette 5a is attached to the scale body. In this figure, 35 is a thermal head, which presses the label paper 8 against the platen roller 21.
Thermal printing is performed on the label 10. The printed label 10 is then peeled off by the dispenser 22 and discharged to the outside. Next, S1 and S2 are reflective photoelectric sensors, which are used to detect whether the loaded cassette is the receipt cassette 5b or the label cassette 5a. As shown in this figure, when the label cassette 5a is installed, the photoelectric sensor S1 receives reflected light and turns on, but the light beam output from the photoelectric sensor S2 is projected inside from the opening 25 and is reflected. Since this does not occur, the photoelectric sensor S2 is turned off. On the other hand, in the case of the receipt cassette 5b, since there is no opening 25, the photoelectric sensor S2 is also turned on in the same manner as S1.

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 2
4 is a photoelectric sensor S3 attached to the scale body side
The light emitted from the light emitting element S3a of the photoelectric sensor S3 is bent in a U-shape, and the light passes through the label paper 8 or the receipt paper 7 and reaches the light receiving element S3b of the photoelectric sensor S3.
It is controlled so that it reaches. In this way, light corresponding to the thickness and transmittance of the sheet passing through the guide plate 18 is received by the light receiving element S3b.

Next, the electric circuit shown in FIG. 1 will be explained. In FIG. 1, 40 is a CPU (central processing unit), and 41 is a measuring section. This weighing section 41 includes the weighing pan 3 shown in FIG. 2, a load cell provided at the bottom thereof, converts the output of this load cell into digital data, and outputs it to the bus line B (FIG. 1) as weight data WD. It consists of an A/D converter. The operation unit 42 includes the keyboard 2
(FIG. 2) and a circuit that generates key data KD corresponding to the operated key of this keyboard 2, and the key data KD is output to the bus line B. The display section 43 includes a display 4 shown in FIG. 2 and a drive circuit that drives the display 4 based on display data supplied from the CPU 40. The ROM 45 has areas E1 to E4 as shown in FIG.
A label printing program, a receipt printing program, and a control program are stored in area E3, and various character (including numbers, symbols, etc.) patterns (dot patterns) are stored in area E. FIGS. 11A to 11C are diagrams showing examples of character patterns, and the area E4 includes the 11th
Hiragana (46
(letters), 16 x 8-dot numbers (10 characters), 16 x
Katakana (46 characters) consisting of 8 dots, Kanji (100 characters) consisting of 16 x 16 dots as shown in Figure 11B,
Katakana (46 characters) consisting of 7 x 5 dots and numbers (10 characters) consisting of 7 x 5 dots as shown in Figure 11C
Various character patterns are stored in advance.
In this case, the character patterns of 16×8 dots and 16×16 dots are mainly used for label printing, and the character patterns of 7×5 dots are mainly used for receipt printing. Further, a character code is assigned to each character pattern, and each character pattern is read out based on this character code.

Next, 45 in Figure 1 is RAM, and this
As shown in FIG. 12, the RAM is provided with a print buffer area EA1, a PLU (PRICE LOOK UP) memory area EA2, a data register area EA3, a total register area EA4, and a working area EA5. .
In this case, the print buffer area EA1 is an area in which a character pattern to be printed on a label or a receipt is written, and has a size (capacity) corresponding to the largest printing section of the label. As shown in Figure 13, the PLU memory area EA2 is an area where the product number, unit price, expiry date, etc. of each product, product name for label printing, and product name for receipt printing are set, and is an area for 100 items. is ensured. Here, the product name to be printed is stored in the product name column for label printing and the product name column for receipt printing, respectively, using the character code of each character. For example, if the product name for label printing of a product with product number "0152" is "Beef Loin Steak" and the product name for printing on the receipt is "Giyuuni Claus", the product name field for label printing will contain 16 x 16 dots of kanji. Character code for “cow”, 16×8 dot katakana “ro”, “ー”,
Each character code of "su"... is stored in sequence. on the other hand,
In the product name column for receipt printing, 7×5 dot katakana character codes of ``gi'', ``yu'', ``u'', etc. are sequentially stored. Furthermore, this PLU memory area EA
2 is performed, for example, by a host computer or manually from the keyboard 2.

The data register area EA3 is an area where data related to products purchased by the customer is written, and as shown in FIG. 14, data for 50 items can be written. The total register area EA4 is
As shown in Figure 14, area EA4 where the number of products purchased by the customer and the total price are respectively written.
-1 and EA4-2.

Next, reference numeral 47 in FIG. 1 is a printer section,
A pulse motor 48 that drives the paper, a drive circuit 50 that drives a thermal head 49 made up of heating resistors γ1 to γn for 128 dots, a shift register 51 into which a one-row dot pattern is written, the photoelectric sensor S1 described above, It is composed of S2 and printer face 52. In this case, the printer face 52 sends a drive pulse MCP for driving the pulse motor, a print pulse DP to the drive circuit 50, a shift pulse CP to the shift register 51, and serial dot data DATA based on the control data supplied from the CPU 40. Output each.

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

[1] When issuing labels In this case, the staff first places the label cassette 5a shown in Figures 4 and 5 into the printer main body.
Attach to. When the label cassette 5a is correctly attached to the main body 1, the photoelectric sensors S1 and S2
(Fig. 1, Fig. 8) respectively output an on signal and an off signal, and the printer interface 52
supplied to 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 cassette data indicating the label cassette to the bus line B. This cassette data is written into working area EA5 of RAM45 via CPU40. Next, the clerk places the product on the weighing pan 3 and inputs the product number using the keyboard 2.
When the product is placed on the weighing pan 3, the weighing section 41
(Fig. 1), weight data WD corresponding to the weight of the product is output. In addition, when the product number is input, the CPU 40 uses the RAM 45 shown in FIG.
PLU data (i.e., unit price, unit price,
Validity days (label printing product name, receipt printing name) are read out and transferred to working area EA5, and weight data WD is also transferred to the same working area EA5. Next, the CPU 40 calculates the price of the product based on the weight data WD and unit price data in the working area EA5, and stores the calculated price data in the 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, each of the above data is displayed on the display 4 (FIG. 2).

Here, single item label (label for one product)
When issuing a message, the staff member presses the print key on the keyboard 2. On the other hand, when issuing a total label (a label on which the total price of multiple products is printed), the clerk presses the plus key on the keyboard 2. When this plus key is pressed, the PLU data and weight data in working area EA5 will be displayed.
The WD and price data are each transferred to the data register area EA3 (Fig. 14) of the RAM 45,
Also, total register area EA4 (Figure 14)
The data in area EA4-1 (initial reset) is incremented, and the price data transferred from working area EA5 is added to the data in area EA4-2 (initial reset). Next, the clerk lowers the product on the weighing pan 3, places the second product on the weighing pan 3, and inputs 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 clerk presses the plus key, each data regarding the second product is stored in the data register area EA3, and
The data (in this case, "1") in area EA4-1 of total register area EA4 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 steps
Proceeding to SP1, it is checked whether the aforementioned cassette data in the working area EA5 is cassette data indicating the label cassette 5a (cassette data indicating the receipt cassette 5b). If it is the label cassette 5a, the process advances to step SP2. Step SP2
Now, determine whether the plus key has been pressed. If the button has not been pressed (in the case of a single item label), the process advances to step SP3 to write the single item label data into the print buffer area EA1. i.e. working area EA
Read unit price data, valid days data, etc. and label printing product name data in 5, convert each read data into a character pattern using the character pattern in area E4 of ROM44, and use this character pattern when printing the label. Write in print buffer area EA1 in the same arrangement as the character arrangement. on the other hand,
If the judgment result of step SP2 is “YES” (the brass key is pressed), the step
Proceed to SP4 and write the total label data to print buffer area EA1. That is,
Convert the total data in the total register area EA4-2 into a character pattern and print it in the print buffer area.
Write in EA1. In this case, the unit price, product name, etc. are not written.

Next, when the process advances to step SP5, the contents of the print buffer area EA1 are sequentially output to the printer section 47. As a result, label printing is performed in the printer section 47, and for example, the label shown in FIG. 16A (in this example, a single item label) is automatically issued. Then, when label printing is completed, label paper is fed (step SP6).
The process ends when the next label reaches the regular position, that is, when the photoelectric sensor S3 (FIG. 9) detects the label gap (step SP7).

[2] When issuing a receipt In this case, the clerk first attaches the receipt cassette 5b shown in FIG. 7 to the main body 1. When the receipt cassette 5b is attached to the main body 1, an ON signal is output from both the photoelectric sensors S1 and S2, and is supplied to the printer interface 52. As a result, cassette data indicating the receipt cassette is output from the printer interface 52, and the output cassette data is
It is written into the working area EA5 of the RAM 45 via the CPU 40. Next, the staff member places the first product on the weighing pan 3, enters the product number, presses the plus key, and then places the second product on the weighing pan 3 in the same way as when printing a total label. , input the product number, press the plus key, repeat this process, and press the print key when the plus key operation for the last (nth) product is completed. Note that the processing performed by the CPU 40 in response to each of the above operations is the same as in the case of total label printing described above.

Next time the print key is pressed, the CPU 40
The process proceeds to step SP1 in FIG. In this case, the determination result at step SP1 is "NO", so the process advances to step SP8. step
At SP8, each data in the total register areas EA4-1 and EA4-2 is converted into a character pattern and written in the print buffer area EA1. Next, when the process advances to step SP9, the contents of the print buffer area EA1 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 SP10, the unit price data, receipt product name data, weight data, and price data on the nth line of the data register area EA3 shown in FIG. Written in EA1. Next, proceed to step SP11.
The contents of the print buffer area EA1 are sequentially output to the printer section 47. As a result, the unit price, product name, weight, and price of the nth product are printed on the receipt paper. Next, proceed to step SP12.
It is determined whether printing has been completed for all products written in the data register area EA3. If the result of this judgment is "NO", the process returns to step SP10, the printing process is performed for the (n-1)th product, and the above process is repeated thereafter. If the determination result at step SP12 becomes "YES", the process advances to step SP13.
In step SP13, the store name, date, etc. are converted into a character pattern and written in the print buffer area EA1, and then in step SP14, the contents of the print buffer area EA1 are transferred to the printer section 47.
Then, in step SP15, a predetermined amount of receipt paper is fed. 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 addition, in the above embodiment, when printing a receipt, a configuration is adopted in which the total number and total price are printed before the individual product data, and the printing order is reversed from that of a receipt issued by a general ECR. However, this is a configuration adopted in relation to label printing control, and is not limited to this configuration.

In the above embodiment, the label/receipt printer of the present invention was incorporated with an electronic scale, but it may be configured separately from the electronic scale and electrically connected. Furthermore, when dealing only with fixed-price products that are not sold by weight, it is clear that there is no need to use it in combination with an electronic cup.

〔Effect of the invention〕

As explained above, according to the present invention, the label product name code and the receipt product name code are automatically switched in response to the conversion of the paper cassette.
As a result, it is possible to issue both labels and receipts without having to reset the product name code in response to cassette exchange.
