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, when you place pork shoulder loin on the plate of this price scale and press the label issue button, you can see its "processing date,""per 100g (yen),""net amount (g)," and "price (yen)." and the product name are printed on the label using a label printer, and the first
A label as shown in the figure will be issued. That is,
According to this label, the product name "Pork Shoulder Loin" is printed by a stamp placed close to the label issuing port, and "55.4.15,""270," and "262" are printed.
"707" is further printed by a printing drum and hammer provided at the label printing opening. The net amount and price are calculated by a computer in the scale and displayed on the display along 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, this insert key is inserted into the slot provided close to the label issuing slot, and the above-mentioned coded "075" is read by the reader installed in the slot and stored in the computer inside the scale. Ru. Based on this memory, the buttons, numeric keypad, etc.
By operating the switch, the unit price and tare weight for this item are set and stored in the computer.

The unit price and tare weight stored in this way become unique data for this insert key, and once the insert key is removed from the insertion slot and inserted again, the product number is read by the reader and the product number is read. The above-mentioned unique data such as unit price and tare weight are displayed on the display section.

However, in some cases, it may be desired to temporarily change the above-mentioned unit price or tare weight for this insert key. In such a case, this temporary data is set by operating the operation button or numeric keypad switch while the insert key is inserted into the insertion slot. Along with this set, the changed unit price and tare amount are displayed on the display section. On the other hand, the changed unit price and tare weight are printed on the label by the label printer.

However, during operation of the label printer, the insert key moves up and down, and at this time, if the user's hand touches the insert key or the product touches it,
The insert key may be temporarily removed from its reading position and then set there again. In such a case, the changed data will be cleared and the original unique data will be displayed on the display while reading the product number.
This data will be printed on a label printer. It would be better if the user noticed this immediately, but the reality is that several labels are already issued for the same item.

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 can be used with peace of mind at all times. 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. When a plug-in product name stamp with the product number written on it is inserted into a predetermined position of the insertion port, the product number is read by the reader and stored by the computer, and based on this memory, the product number is read by the reader and stored by the computer. A toll scale with a label printer configured to read data unique to a product name stamp, further comprising a temporary data changing means and a holding means for holding the data changed by the means, and the product name stamp is inserted into the product name stamp by the temporary data changing means. It is possible to write data different from the unique data to the product name stamp while it is inserted in the mouth, display it on the display section, and supply it to a label printer, and also write the product number of the product name stamp. In the case of successive reading by the reading device, the different data in the display section and the label printer are not changed by the operation of the holding means, and the product name stamp of a product number different from the product number is changed to the product name stamp. The rate scale with a label printer is characterized in that when the product number is read by inserting the stamp into the predetermined position of the insertion port, the different data written by the temporary data changing means is cleared.
