Description

DETAILED DESCRIPTION OF THE INVENTION The present invention measures, for example, the weight of an object to be weighed,
The present invention relates to a label printer that automatically issues labels based on the measurement results.

This type of label printer consists of a weighing pan, a weight detection section that measures the weight of the object placed on the weighing pan and outputs a weight signal corresponding to the same weight, and a weight detection section that measures the weight of the object placed on the weighing pan and outputs a weight signal corresponding to the same weight. A calculation device that calculates the price of the object to be weighed based on the weight signal, and a calculation device that calculates the price of the object to be weighed, and the
It is configured with a printing device, etc. that prints the tare weight, price, and corresponding barcodes on the label. In this case, the product name, unit price, valid days, etc. of the object to be weighed are written in advance in the preset memory under the control of the above-mentioned arithmetic device, and the operator inputs the code corresponding to the product name of the object from the numeric keypad. When input, the product name data, unit price data, validity period data, etc. corresponding to the code are read from the preset memory, and the label is printed based on the read data.

In the following description, a set of product name data, unit price data, valid days data, etc. set correspondingly for each product name will be referred to as an item.

By the way, the above-mentioned writing to the preset memory is performed using, for example, a numeric keypad, but in the case of conventional label printers, the remaining current memory capacity (unwritten memory portion) is It was inconvenient not to know the capacity.

Therefore, the present invention provides a label printer that always displays the capacity of the unwritten area of the preset memory when writing to the preset memory, and calculates the capacity of the unwritten area of the preset memory. an arithmetic control unit that divides the obtained capacity by the average item capacity and outputs the division result;
The present invention is characterized by providing a register for storing output data of the arithmetic control section and a numeric display for displaying the contents of this register.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the main parts of a label printer according to the present invention, and in this figure, reference numeral 1 denotes an input device having a numeric keypad and the like. This input device 1 is for inputting data to be written into the preset memory 2, that is, product name code, unit price, effective days, quantity, tare weight, product name, etc. The data is supplied to the calculation control section 3.
The arithmetic control section 3 first sequentially writes the data supplied from the input device 1 into the preset memory 2 in the manner shown in FIG. In addition, Figure 2 shows the product name code,
Unit price data is written in 5 words (1 word = 4 items), valid days data is written in 2 words, quantity data is written in 5 words, tare weight data is written in 3 words, and product name data is written in 8 words. It shows that

Next, the calculation control unit 3 calculates the number of words in the unwritten area of the preset memory 2, and calculates the number of words to be loaded in the preset average item capacity (i.e.,
The result of this division, that is, the number of items that can be written from now on, is stored in the register 4. The number of writable items stored in this register 4 is displayed by a numeric display 5.

Next, a method of using the preset memory 2 used in this embodiment will be explained.

Conventionally, preset memory has been used with a fixed number of words in an item. However, this method of use has the disadvantage that memory is wasted when the number of digits in product name data is small. Therefore, in this embodiment, a method is adopted in which the number of words in each item is made variable. That is, in this embodiment, the number of words is fixed for data whose data length does not change relatively, such as product name code, unit price data, tare weight data, and effective days data. The number of words is variable for data that varies greatly depending on the product name. As a result, preset memory 2
can be used more effectively.

Note that the average item capacity in the embodiments described above does not necessarily have to be an accurate average of the number of words constituting each item. It should be about average.

Further, the numeric display 5 in the above-described embodiment
may be newly provided, or the amount display or the like provided in the label printer may also be used.

Furthermore, the arithmetic control section 3 can also be used as an arithmetic circuit or the like provided in the label printer.

Furthermore, data may be written into the preset memory 2 by reading data written in barcodes with a pen scanner instead of using a numeric keypad or the like.

Further, the present invention is applicable even when the preset memory 2 is used in a manner in which the number of words in an item is fixed.

Furthermore, the present invention is of course applicable not only to label printers that issue labels by measuring weight, but also to label printers that issue labels simply based on data in memory (label printers without a weight measurement function).

As explained above, according to the present invention, the number of writable items in the preset memory is determined by the arithmetic control section, and the determined result is displayed on the numerical display. An advantage can be obtained that the number of writable items at that time can be known at all times during writing to the memory.
