DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toll scale with a label printer.

Recently, price scales with label printers are being used in supermarkets and other places. For example, if you place a swift loaf on the plate of this price scale, you will see its "processing date", "effective date", "per 100g (yen)", "net amount (g)", "price (yen)" and product name. is printed on a label by a label printer, and a label as shown in Figure 1 is issued. In other words, according to this label, the product name "Swift Loaf" is printed by a stamp placed close to the label issuing port, and "55.4.15", "55.4.18", "270", "262"
"707" is further printed by a printing drum and hammer provided at the label issuing port. The net amount and price are calculated by the computer in the scale and displayed on the display together with the unit price "270".

Examples of the above-mentioned stamps include price scales with label printers that use insert-type product name stamps, so-called product name insert keys. This product name insert key contains the product number, e.g.
075 is displayed and written in code. When in use, the insert key is inserted into a slot provided close to the label issuing port and set in a predetermined position. Then, the above-mentioned encoded "075" is read by the reading device installed in this insertion port and stored in the computer in the scale. Based on this memory, the unit price and tare weight for this item can be set by operating a button, numeric keypad switch, or rotary switch on the operating section of the scale, and can be stored in the computer. Additionally, the processing date and effective date are set on the computer by operating a button, numeric keypad switch, or rotary switch, but when handling many types of items, even if the processing date is the same,
Effective dates often vary. In such cases, the effective date must be set each time.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a toll scale with a label printer that is more efficient than the conventional one. According to the present invention, this purpose is to provide a toll scale with a label printer, which comprises a computer, a display section, a label issuing port, an insertion port provided adjacent to the label issuing port, and a reading device provided in the insertion port.

It is peeled off and discharged.

An insert base 14 is fixed to the casing 3 above the label issuing port 12, and the insert base 14 is opened at the front and bottom to insert an insert key 1, which will be described later.
6 insertion ports 15 are formed.

The lower part of the casing 3 protrudes forward,
A placing plate 9 is provided on top of this. During a weighing operation, when an item is placed on the placing plate 9, its weight and price are calculated by a computer as is well known, and the results are displayed on the first display section 5. Further, the weight of the tare and the unit price of the item at this time are displayed on the second display section 6.

FIG. 3 shows a perspective view of the insert key 16 applied to this embodiment. The insert key 16 is formed by cutting out and bending a plate made of a magnetic material as shown in the figure, and the stamp 19 is fixed at a pair of front bent portions 17a and 17b. For example, "Swift Loaf" is engraved on the bottom surface of the stamp 19. insert key 16
A thin code plate 20 is attached to the front part of the upper surface of the insert key 16, and the surface of the code plate 20 is selectively painted black to represent the code 21 of the insert key 16 with the product number "075". The black portion forms a non-light reflecting surface, and the other portions form a light reflecting surface. The code 21 formed in a band shape is composed of, for example, 10 bits including a parity bit, and a non-reflective bit 22 and a reflective bit 23 for positioning are formed at both ends of these bits.

The insert key 16 is further formed with a protruding knob part 18, and the insert key 16 is inserted into the insertion opening 15 of the insert base 14 by pinching this part with fingers. As shown in FIG. 4, a band-shaped permanent magnet 25 is fixed to the lower surface of the upper wall of the insert base 14, and a reading device 24 is further fixed in front of this. The reading device 24 has each bit 21, 22, 2 of the insert key 16.
3, an optical detection means consisting of a pair of a light emitting element and a light receiving element is provided. The insert key 16 is inserted so that the bent portion 17b of the insert key 16 contacts the right side wall of the insert base 14, and is set in a predetermined position by contacting the rear wall 14a of the insert base 14. Ru.
As shown in FIG. 4, the insert key 16 is fixed at this position by being attracted by the permanent magnet 25. Each optical detection means of the above-mentioned reading device 24 is
Opposing each bit 21, 22, 23, a light receiving element detects whether or not the light from the light emitting element is reflected by each bit 21, 22, 23. The read signal is stored in the computer in the scale 1, and the content of the read signal "075" is displayed on the first display section 5 together with "PLU" (Price Look-Up). In addition, the second display section 6
Correspondingly, the tare weight and unit price stored in the computer are displayed. At this time, it is assumed that the operation knob 8 is set at a position for displaying an insert key, for example, at d. Further, the positioning bits 22 and 23 detect that the insert key 16 has been inserted into a predetermined position.

As described above, according to this embodiment, when the insert key 16 is inserted into the predetermined position of the insert base 14, the product number "075" of the insert key 16 is displayed as "PLU" on the first display section 5.
(Price Look Up), the user can definitely confirm that the corresponding code of the desired insert key 16 has been read and stored in the computer in the scale 1, and can rest assured. You can continue with subsequent operations. especially,
A secondary effect is that if the product number "075" of the insert key 16 is difficult to see, displaying this product number on the first display section 5 allows you to confirm it.

According to this embodiment, since the insert key 16 is configured to make a "pop" sound when it is set in a predetermined position, the positioning can be comfortably confirmed. After the product number of the insert key 16 is stored in the computer, the insert key 16 may be freely moved within the insertion opening 15 of the insert base 14. It is moved to approximately the center and fixed by the permanent magnet 23 at this position.

This allows the product name to be always printed in the center of the label, which has the effect of making it easier for consumers who have purchased the product to recognize the label when they see it.

According to the present invention, a predetermined integer α corresponding to each insert key is set in the computer in response to a read signal when the insert key is inserted into the insertion port 15 and its product number is stored in the computer. This integer α can be registered arbitrarily, but according to this embodiment, α=0,
It is configured to take any integer among 1, 2, . . . 99, and for example, α=4 is set for the illustrated insert key 16. In addition, the item "Swift Loaf" corresponding to this insert key 16
The processing date "55.4.15" is set by switching the knob 8 to position a, for example, and operating the numeric key switch 7. At the same time, "55.4.15" is displayed on the first display section 5 as shown in FIG.
Next, turn the knob 8 to set the rotary switch to the PLU reception position, and insert the insert key 16 in this state. The effective date of the item "55.4.18" will be automatically calculated and the label printer will be sent to the label printer section. This result is provided. In other words, the calculation 15+α-1=15+4-1=18 is performed in the computer, and the result is "55.4.
18'' is supplied to the first display unit 5 and also to the label printer. In addition, the unit price of the item whose name is engraved on the stamp 19 of the insert key 16, the tare weight for this item, etc. can be written into the computer by appropriately switching the knob 8 and operating the numeric key switch 7. , at the time of weighing, the first display section 5 and the second display section 6 display the weight of the item being weighed,
The price, tare weight, and unit price are displayed in a publicly known manner. When printing a label, the printing drum and hammer inside the casing print the data "55.
4.15'', ``55.4.18'', ``270'', ``262'', and ``707'' are printed, and as the insert base 14 moves downward, the stamp 19's stamp ``Swift Loaf'' changes as shown in Figure 1. Printed at the label position. Although the illustration is omitted, insert key 16
A long hole is formed in the upper wall portion corresponding to the stamp 19, and stamp ink is supplied to the stamp 19 through this hole.

In addition, in the case of an insert key with α=1, the processing date and the effective date are the same, and in the case of an insert key with α=0, when the knob 18 is switched to the PLU reception position and the insert key 16 is inserted. However, the effective date of the item is set by operating the ten key switch 7 without calculating the effective date. That is, since the validity period cannot be specified for the item corresponding to the insert key with α=0, the date cannot be calculated using the PLU, and must be set each time using the numeric keypad. Then, for the insert key where an integer other than α=0 (1, 2...99) is set, the processing date is set, and when the insert key is inserted into the insertion slot 15, the effective date of the item is automatically set. will be done.

Although the embodiments of the present invention have been described above, the present invention is of course not limited thereto, and various modifications can be made based on the technical idea of the present invention.

For example, although a light reflective surface and a non-reflective surface are used as means for writing the product number code on the insert key, magnetic writing may be used instead. In this case, the reading device is provided with a magnetic head instead of the optical detection means.

In addition, a display part for displaying the weight and price was used to display the part number of the insert key, the processing date, and the effective date of the item, but of course a separate dedicated display part was provided, so that the part number was always displayed. , the processing date and effective date of the item may also be displayed.

In addition, in the above embodiment, a predetermined integer α−
1 was added and the effective date was set, but instead of the effective date, the best-before date, processing date, processing time, and
Instead of the effective date, a valid time or best-before time may be set. Particularly when the product is perishable, such as sashimi, having the expiry time or best before time printed on the label is very kind to consumers and can gain trust.

As described above, according to the present invention, by setting the insert key in a predetermined position and setting the processing date or time, the effective date or time is automatically set, so that work efficiency can be greatly improved. .
