Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label printer that prints weight, unit price, price, etc. on a label attached to a product.

Generally, the printing section of a label printer has consumable parts.
Whether or not to replace such consumable parts during a regular inspection is normally determined based on the number of labels actually printed by the label printer. However, conventional label printers are not equipped with a device to count the number of sheets issued, making it difficult to accurately determine when to replace consumable parts, and requiring detailed service to users. I couldn't.

An object of the present invention is to provide a label printer that solves the above problems. Therefore, the present invention includes a weighing section that weighs the article to be weighed and generates a weighing signal, a setting section that generates a unit price signal corresponding to the unit price of the article to be weighed, and a weighing signal and a unit price signal. a calculation section that generates a price signal based on the measurement signal, a printing section that prints on the label based on the weighing signal, the unit price signal, and the price signal, and a stability detection section that supplies a printing command signal to the printing section when the weighing signal is stable. , and a nonvolatile integration counter that counts the number of times a print command signal is generated.

Since the label printer configured in this way counts the number of times a print command signal is generated, the number of labels to be issued can be known. In particular, this counting is done by a non-volatile settlement counter, so even if there is a disturbance such as a power outage, noise, radio waves, sparks, etc., the count value will not change or be erased, and labels will be issued accurately. You can know the number. Therefore, it is possible to accurately determine when to replace consumable parts based on the number of labels issued.

In particular, when printing quality deteriorates in a printing section using a thermal head, conventionally it has not been possible to accurately determine whether the quality deterioration is due to a malfunction of the thermal head or due to the lifespan of the thermal head. According to the present invention, it is possible to accurately determine whether the problem is due to the problem due to 14 or due to the lifespan. Therefore, it is possible to improve quality, guarantee, and service.

Hereinafter, the present invention will be explained in detail based on one embodiment shown in the drawings. In the figure, reference numeral 2 denotes a weighing section that weighs an article to be weighed placed on a tray (not shown) and generates a weighing signal according to its weight. This measurement signal is supplied to the calculation section 4.

In addition to the measurement signal, the calculation unit 4 is also supplied with a unit price signal from the setting unit 6 . The unit price signal represents the price (unit price) per unit weight of the article to be weighed on the tray. The calculation unit 4 calculates the weighing signal and the unit price signal to generate a price signal representing the price of the article to be weighed on the tray. This price signal is supplied to the display section 8 together with the measurement signal and the unit price signal. Display section 8
displays the weight, unit price, and price based on these signals.

The weighing signal, unit price signal and price signal are also supplied to the printing section 10. The printing unit 10 is also supplied with an item name signal from the setting unit 6 that represents the item name of the liquid measurement item on the tray. The printing section 10 prints the weight, unit price, price, and product name on the label in a predetermined format based on the total tfk signal, unit price signal, price signal, and product name. This is done whenever the supply is supplied.

This print command signal is generated by the stability detection section 12.

The stability detection unit 12 generates a print command signal when the weighing signal, which has been fluctuating due to placing the object to be weighed on the mounting plate, becomes stable. As a result, the weight and price are printed on the label when the weighing signal is stable.

The print command signal is also supplied to an integration counter 14, which counts the number of times the print command signal is generated, that is, the number of times a label is issued. This integration counter 14 is non-volatile, so even if there is a power outage, noise, radio waves, sparks, etc.
Once the count value has been cleared, it will not be changed. Furthermore, this totalizing counter is installed on the printed circuit board inside the label printer, so no matter how you operate the setting buttons or other switches on the setting section installed outside the label printer, it will not count. ;4 is configured so that the value cannot be changed or deleted. In addition,
The count value is reset by operating a reset switch provided inside the label printer, or by taking the counter out of the label printer and using a separate write-only device. This integration counter 14
The count value is displayed on the display section 8 by operating the call key 1G.

According to this label printer, the number of labels issued to date is displayed on the display section 8 by pressing the call key 16 at the time of periodic inspection or when a printing defect occurs. Therefore, based on this, it is necessary to determine whether the consumable parts need to be replaced or whether the consumable parts need to be repaired.
It is possible to make decisions quickly and provide detailed services to users.

The information may be printed on the label, or may be displayed on the display section 8 at the same time as being printed on the label. In addition, the label printer of this embodiment prints weight, price, and unit price, but it also prints a flat rate label with a fixed price printed on it, a subtotal label with a subtotal of the amounts printed so far, and 1. This invention can also be applied to a label printer that can issue a total label on which the total amount of money printed during the day and a classification label on which the classification of products is printed. In that case, it is sufficient to supply the printing command signal for each of the above-mentioned labels to the monkey counter 14.
