TECHNICAL FIELD OF THE INVENTION
The present invention relates to a charge scale for displaying a charge corresponding to the weight of an article, and more particularly, to a digital charge scale capable of easily responding to a change in a charge system.
[0002]
[Prior art]
As one of the scales, there is a charge scale for presenting the weight of an article and its shipping cost. As a conventional charge scale, there is a scale that identifies the weight and size of a weighing object placed on a weighing pan, calculates a charge in a CPU based on the identification result, and displays the weighed weight and the charge (for example, Patent Reference 1).
[0003]
In addition, as a special function of the scale, a display element that can be turned on at equal intervals is provided, and the display elements that are turned on according to the weight are sequentially changed, and it is determined whether or not the weight approaches the target weight. There is a scale that can do this (for example, Patent Document 2).

[0013]
Further, the digital toll scale of the present invention further comprises a weight value display section for numerically displaying the weight value of the article weighed by the weight weighing means.
[0014]
In addition, the digital fee scale of the present invention further includes a reference weight changing unit that can change a minimum unit weight at which the display element is turned on,
It is assumed that the seat has a charge corresponding to a plurality of unit weights.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
In the digital toll scale of the present invention, a plurality of display elements that are turned on according to the weight of the weighed article are used, and the display elements are arranged at equal intervals. Adjacent to these display elements, a sheet on which a fee is described is provided. The lines indicating the range (classification) of the weight of the seat need not be evenly arranged, but are appropriately arranged based on the weight range of the fee system. In addition, the minimum unit weight when the display element is turned on can be changed, and a sheet indicating a charge system corresponding to the unit weight is provided.
[0016]
【Example】
A mail scale according to an embodiment of the present invention will be described with reference to the drawings.
[0017]
FIG. 1 is an external view of a mail scale according to the present invention. FIG. 2 is a block diagram showing an internal connection in the postal scale. The postal scale 1 includes a placing plate 2 on which an article whose weight is to be weighed is placed.
[0018]
In addition, on the front side of the placing plate 2, an on switch 3 and an off switch 4 of the power supply, a weight display section 5 for displaying the measured weight value by a numerical value, and dots are displayed according to the measured weight value. There is a dot display section 6. The dot display section 6 is a liquid crystal display (LCD), in which dots are provided at regular intervals in a certain direction. A sheet 7 on which postage is described is provided adjacent to the dot display section 6.
[0019]
Further, there are provided a dot unit display section 8 for indicating how many grams each dot of the dot display section 6 represents, and unit change switches 9a and 9b as reference weight changing means capable of changing the unit of one dot. .
[0020]
An arithmetic control unit (CPU) 10 is provided inside the scale, and performs switch input signal processing of each unit, calculation of a weight value, and control of each display. In addition, a load detection unit 20 that is connected to the weighing pan 2 and that outputs a signal corresponding to the weight is also connected to the arithmetic and control unit 10.
[0021]
Next, the operation of the mail scale 1 of the present embodiment will be described.
[0022]
When the ON switch 3 is pressed, the power of the postal scale 1 is turned on. 0 g is displayed on the weight display section 5 as an initial value. Since the dot display section 6 is 0 g, all dots are turned off. The dot unit display section 8 displays a weight value per dot.
[0023]
Here, when a weighing object (mail) is placed on the placing plate 2, the weighing of the article is started. The load detection unit 20 outputs a signal corresponding to the weight, and the arithmetic and control unit 10 calculates the weight of the article from the signal, and displays the weight value on the weight display unit 5. Here, it is assumed that the measured value is 125 g.
[0024]
Dots corresponding to 125 g are lit on the dot display section 6. At present, since 5 g is displayed per dot, 25 dots are lit.
[0025]
As shown in FIG. 3, the sheet 7 provided below the dot display section 6 is described with a plurality of lines for dividing the range of dots, and a charge corresponding to the range, for example, 390 yen. Are also described. Therefore, the user can understand the charge according to the weight of the article from the relationship between the currently lit dot and the sheet.
[0026]
When the weighing of the articles is completed, the weight display section 5, the dot display section 6, and the dot unit display section 8 are turned off by pressing the off switch 4, and all the operations of the mail scale 1 are completed.
[0027]
In this postal scale 1, the sheet 7 can be easily peeled off and a new sheet can be stuck. That is, when the postage is revised, a new sheet on which a new fee system is described may be re-attached from the previous sheet. As a result, even if the postage is revised, it is possible to easily cope with the revision.
[0028]
In the mail scale of the present embodiment, the weight per dot can be changed. By pressing the unit change switches 9a and 9b, the current unit per dot can be changed.
[0029]
As shown in FIG. 4, a plurality of sheets are stacked, and can be folded back from the middle in the lateral direction. Each layer of the sheet describes a different fee structure depending on the type of mail, such as a sealed letter or a parcel. In FIG. 4, the charge system for displaying 5 g per dot is described below the surface A, and the range of weight division when displaying 5 g is described above the surface A. Further, the charge system at the time of displaying 25 g is described below the surface B, and the range of weight division at the time of displaying 25 g is described above the surface B. Also, on each side of the sheet, the value of the unit weight of the fee system is described in the upper right so that the current weight per unit indicates the fee system at the time of g.
[0030]
Here, the effectiveness of the mail scale will be further described as an embodiment of the present invention.
[0031]
If the fee is revised at intervals of the same weight range, it is possible to realize without having to write the fee using the display element and the sheet as shown in the embodiment of the present invention. In general, the idea is as follows. For example, as shown in FIG. 5A, six display elements and a sheet indicating a price below the display elements are provided. The display elements are designed to be turned on every 50 g. If the weight range and the fee system are as shown in FIG. If the weight of the article is 75 g, the second display element (B) is turned on, and it can be understood that the fee is 140 yen.
[0032]
However, if the weight range (weight division) is changed in accordance with the change in the fee system, or if only the weight range is changed, the display elements in different weight ranges will light up, and the above-described display elements will be turned on. With such a scale, even if the sheet on which the fee is described is changed, it cannot be handled. For example, in the case where the range of weight is divided every 60 g, a charge scale designed for every 50 g cannot respond even if the charge described on the sheet is changed.
[0033]
On the other hand, in the fee scale of the present invention, since the line indicating the range of the fee to be described on the sheet is described based on the weight range without fixing the line, it is possible to flexibly cope with the change of the weight classification. Can be handled without any problems.
[0034]
Further, the charge scale of the present invention has a configuration in which, when responding to the change of the weight division, it is possible to change the minimum unit weight at which the display element is turned on even if the change cannot be made only by changing the line of the charge sheet. Therefore, it is possible to cope with a new fee system.
[0035]
Although the postal scale shown in the embodiment can be changed to a plurality of dot display units, this means that it can respond even when the minimum unit of the weight range (division) is changed. Is what you do. For example, in the case where the dot display is turned on every 20 g, in the case of a fee system in which a weight range is set every 100 g, there is no problem using 5 dots per one weight range. When the range is changed, a dot display that lights up every 20 g is calculated using 2.5 dots, and it is not possible to respond accurately. However, for example, if the dot display can be changed so as to light up every 10 g, it is sufficient to use 5 dots per 50 g, which can cope without any problem.
[0036]
Further, the postal scale shown in the embodiment also means that the maximum display weight can be changed.
[0037]
When the weight per dot is 5 g, only 250 g can be displayed if the number of dots is 50. However, if the weight per dot is changed to, for example, 25 g, dot display can be performed with a weight of up to 1250 g if there are 50 dots. In this way, by combining the configuration in which the weight unit per dot can be changed and the sheet on which a plurality of fee systems are described, it is possible to change the maximum display weight even with a limited number of dots. .
[0038]
Here, a case where two or more sheets are combined and described as a case where a plurality of fee systems are described has been described. However, even if a larger number of sheets can be used to support a large number of fee systems. Good. Alternatively, a configuration in which a charge system is described in a plurality of stages on one sheet may be adopted.
[0039]
Further, in the present invention, a sheet is used. However, as shown in the embodiment, the sheet does not need to be constituted only of a portion adjacent to the display element. It is also possible to use a sheet that covers up to the unit, and that a fee is described in part of the sheet.
[0040]
Although the present embodiment has been described as a postal scale, the present invention is not limited to this, and the present invention can be applied to a charge scale for calculating a certain charge from the weight of an article.
[0041]
Also, the display devices arranged at regular intervals in a certain direction have been described as a dot display type liquid crystal display. However, the present invention is not limited to this, and an LED type display device may be used. Also, in the display method, the present invention weighs from 0 g. All the dots up to the dot are turned on, but a display method in which only the dot (display element) corresponding to the weight is turned on may be used.
[0042]
【The invention's effect】
In the digital fee scale according to the present invention, a display unit in which display elements that are turned on at a constant weight are provided at equal intervals, and a line that indicates the correspondence between the fee and the display element is indicated based on the weight range of the fee system. When a fee is revised, as in the case of mail, there is no need to replace the memory in which the fee according to the weight is stored as in the conventional case, such as a postal matter. All that is required is to replace the sheet with the revised fee. Such exchange is possible even if not a specific technician, and it is possible to instantly provide a scale with a new charge system. In addition, since a new fee system can be dealt with only by exchanging a seat, it can be provided at a lower cost as compared with a conventional case where memory is exchanged.
[0043]
Further, in the digital toll scale of the present invention, since the weight value of the article is also displayed as a numerical value, the actual weight can be grasped.
[0044]
Further, the digital fee scale according to the present invention can change the minimum unit weight at which the display element is turned on, so that it can cope with a change in weight division. Furthermore, the maximum display weight that can be displayed with a limited number of display elements can be changed, and the range of the weight that can be displayed for a fee can be expanded.
