Abstract

PURPOSE:To make weighing operation easy and simple by changing the color of specific part or the whole of a display device when measured weight enters a preset range at the time of weighing. CONSTITUTION:When a set mode shows a PLU (price lookup memory) 6, a unit price, an article name, a target value, etc., are inputted on a keyboard 5. Then when an issue mode is entered, the PLU 6 is made access and then a target value is inputted on the keyboard 5. Weighing on the scale 4 is performed and then the difference between its weighed value and the target value is calculated and used to look up a color table 10, thereby determining a color. Consequently, frame buffers 12, 13, and 14 are selected and a display device 15 makes a display in the selected color.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic price scale used in label printers and the like.

2. Description of the Related Art In general, this type of electronic fare scale is provided, for example, as shown in FIG. That is, a ROM 2 in which programs are set to a CPU that controls each part is connected to a work RAM 3 in which various data are stored. Connected to the CPU 1 are a scale 4 configured with a load cell, etc., a keyboard 5 equipped with various keys, and a PLU 6 in which product codes, product names, unit prices, tares, effective dates, etc. are set in advance. Furthermore, a target weight display 7 for displaying the target weight, a current weight display 81 for displaying the current weight, and a product name display 9 are respectively connected.

In such a structure, the display state of the product name display 9 that displays various data and messages is black and white or greenish, the target weight display 7 displays the target weight, and the current weight display 7 displays the current weight. Reference numeral 8 denotes a fluorescent display tube consisting of seven segments, and its display state is green.

On the other hand, some devices are equipped with an indicator lamp (not shown) that lights up to indicate when the measured weight value falls within a certain range with respect to the target weight value.

Problems to be Solved by the Invention Even though there is an indicator lamp that indicates whether or not the target weight value is within a predetermined range, it is provided separately from the indicator that displays the weight value. , sometimes we overlook it. In particular, it is difficult to notice the lighting of the indicator lamp when looking at the display, and the work must be done with care.

Means for solving the problem: In an electronic price scale equipped with a PLU in which product code, product name, unit price, tare weight, effective date, etc. are preset, and a display that displays data and other information in color, a color table for setting the display color of the display device in a predetermined range and other ranges based on the target weight value of the weighed weight; and a display controller for selecting a color from the color table.

When the weighed weight falls within the preset range during weighing, the color of a specific part or all of the display changes, so you can easily recognize that this state has occurred, and this makes it easier to carry out weighing operations. This makes it easier.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. Components that are the same as those described with reference to FIG. 3 are designated by the same reference numerals, and description thereof will be omitted. The present embodiment relates to a label printer with a scale, and first, a color table 1o is provided for setting display colors on a display in a predetermined range based on a target weight value of a weighed weight and in other ranges. It is being

The color set in this color table 10 is, for example, "blue".
There are three colors: "green" and "red", and they are divided into three levels depending on the error range with respect to the target weight value. For example, "blue" is selected in a range close to the target weight value and within the tolerance, "green" is selected in a certain area beyond that range, and if the weight is far away from the target weight value, "green" is selected. "Red J is set to be selected.

A display controller 11 is connected to the CPU 1, and the display controller 11 has the aforementioned "blue" [
Green J [Frame buffer 1.2 corresponding to each color of Red J]
, 13.14 are connected.

Further, a display 15 is connected to the display controller 11 and has a function of changing the color of a specific part or all of the display.

The operation of such a configuration will be explained based on FIG. 2. First, in order to set the color to be displayed based on the amount of deviation from the target weight, a setting mode is entered by operating a mode switch (not shown). Therefore, the correspondence between the amount of error for the target weight and the colors in the color table 10 is manually determined using the keyboard 5. Since there are three colors, ``blue,''``green,'' and ``red,'' a range is set for each.

Next, in the setting mode, if PLUG is to be set, the unit price, product name, target value, etc. are input using the keyboard 5.

When the issue mode is selected, the target value is input using the keyboard 5 after calling up PLUS. and,
When weighed using the scale 4, the error between the measured value and the target value is calculated, and the color is determined by referring to the color table 10 based on the calculation result.

As a result, the frame buffers 12, 13, and 14 are selected, and the selected colors are displayed on the display 15. A label is issued only when the amount of error is within the minimum allowable error, that is, within the range of "Blue J".If the displayed color is not "Blue", the scale at the time of weighing is The weight to be weighed on the tray 4 is adjusted according to the displayed color. For example, in the case of "green" display,
This is a slight error with respect to the target value, and if it is displayed as "red", it means that it is significantly different from the target value, so the adjustment of the weighed object is made depending on the state. Therefore, the weighing operation becomes extremely easy and there is no chance of overlooking the display.

Effects of the Invention As described above, the present invention provides an electronic price scale that is equipped with a PLU in which product code, product name, unit price, tare, effective date, etc. are set in advance, and a display that displays data and other information in color. a color table for setting a color to be displayed by the display device in a predetermined range based on a target weight value of the weighed weight and another range, and a color table for setting a color to be displayed by the display device based on the weighed weight; Alternatively, a display controller for selecting all colors from the color table is provided, so that when the weighed weight falls within a preset range during weighing, the color of a specific part or all of the display changes,
Thereby, it is possible to easily recognize that such a state has been reached, and therefore, the weighing operation can be performed easily and simply.
