Abstract

The broken bill face value measuring instrument is used in measuring the area ratio between the residual bill part to the whole bill face. The broken bill face value measuring instrument has one transparent plastic plate in size the same as the complete corresponding bill and divided into 100 small checks accounting for 1 percent of the bill area. It has obvious thick line marks to show 20 % and 50 % area, and makes it possible to measure the residual area fraction of the broken bill easily and accurately.

Description

A kind of broken bill face value measuring instrument

Affiliated technical field:

The present invention relates to a kind of instrument that can help people to measure the broken bill face value damaged condition.

Background technology:

Regulation according to head office of People's Bank of China: the rmb paper currency nominal value damage (lacking) 20% with interior convertible fully; Convertible half volume in (lacking) 20% to 50% scope of damage; Damaged condition will not be exchanged greater than 50%.

At present, the worn coin of each specialized bank business hall of China is exchanged window, there is not desirable instrument to assist business personnel to measure the damaged condition of worn coin, generally based on range estimation, if but not by effective survey instrument, be difficult to judge accurate data, particularly near the situation of exchanging boundary, for example: broken partial section is 21% of a former nominal value area; 19%; Incomplete part and appears at the middle part not on the limit, especially situation such as out-of-shape is difficult to promptly and accurately judge, the visual observation that causes the salesman sometimes is inconsistent with client's (worn coin supplier), disputes on and produce.

The objective of the invention is: for worn coin is exchanged the window broken bill face value area measurement instrument accurately of providing convenience, thereby judge fast: whether exchanged; Half volume is still in full, has also improved salesman's work efficiency simultaneously, avoids unnecessary dispute.

Summary of the invention:

The technical solution adopted for the present invention to solve the technical problems is:

With a transparent plastic plate, big or small and corresponding Currency Type (as one hundred yuan of certificate of the 5th plate) nominal value is identical, use lines (carving or seal) to its wide and long ten five equilibriums above, form the rectangle grid of 100 identical sizes, each grid is one of percentage of nominal value area, and there is the tangible thick line line of different colours (or with) mark at 20 percent and 50 percent position, when the user is placed on this instrument on the worn coin, be easy to, and exactly the ratio of broken partial section area and former nominal value area judged.Shown in (see figure 1).

Also the invention will be further described for two example two below in conjunction with accompanying drawing:

As shown in Figure 1, mark 100 identical rectangle grid of size on the transparent plastic sheet, (because length and width are all by ten five equilibriums) each grid is 1% of the former nominal value of tested worn coin, and there is thick line to represent at 20% position on four limits, 50% position also distinguishes with thick lines, as long as this instrument is placed on the worn coin, align in three limits, is easy to analyze the ratio of its broken partial section and former complete nominal value area.

Example 1: measure the situation of disbud, as shown in Figure 2:

The residual limit (residual fraction is represented with green line) of worn coin and the thick vertical line of representing 20%, form 2 triangles, be easy to find out, 6 grid areas that 6 grid that the A place is drawn by residual limit are corresponding with the B place are big, therefore triangle A area is greater than triangle B area, also be damaged part greater than 20%, less than 50%, can only exchange half volume.

Example 2: measure the broken worn coin that lacks in middle part, as shown in Figure 3:

Middle part broken partial section (residual fraction is represented with green line) the A place of worn coin accounts for 18 grid, and B place broken partial section is less than the area of a grid, clearly: the A place adds the B place less than 20% the total area, also be intact part greater than 80%, exchange in full.

As can be seen, this kind worn coin measuring instrument has characteristics such as easy to use, directly perceived, accurate than survey instruments such as ruler, set squares from the above example.

Claims (3)

1. the present invention relates to a kind of broken bill face value measuring instrument, it is characterized in that: on the transparent plastic sheet of the identical size of corresponding value of money, carving (seal) has the grid of 100 equal sizes, each grid is one of percentage of nominal value area, and there is tangible thick line (or lines of different colours) to mark at 20 percent and 50 percent position, make the user quick, and judge brokenly the ratio that lacks part and former nominal value area exactly.

Such as claim 1 the grid that are carved with 100 equal sizes of art, it is characterized in that: on the transparent plastic sheet identical with corresponding value of money nominal value, with lines with its wide and long ten five equilibriums, and 100 sub-boxes that size is identical that form, its width and length are respectively 1/10th of nominal value width and length; Area is one of percentage.

Such as claim 1 the position 20 percent and 50 percent of art have tangible thick line to mark, it is characterized in that:, mark with difference and the thick line of other lines or the lines of other color at 1/5th places up and down and 1/2nd places of this transparent plastic sheet.
