[0017] Combine figure 1 with figure 2 , The residual currency ratio control ruler includes a straight horizontal ruler 1 and a vertical ruler 2 perpendicular to each other. The horizontal ruler 1 is engraved with a scale 8, and the horizontal ruler 1 is pasted with a flat plate 4, and the vertical ruler 2 is at the center A rectangular plate-shaped end support plate 3 is vertically arranged. The end support plate 3 is perpendicular to the horizontal ruler 1. The vertical ruler 2 is vertically provided with a cylindrical rail rod 6 on the side surface. The rail rod 6 is parallel to the horizontal ruler 1, and the rail rod 6 is A tube-shaped sleeve 7 is sleeved. The side of the sleeve 7 is vertically provided with a straight rod-shaped detection rod 5. The length of the detection rod 5 is equal to the distance between the track rod 6 and the level 1.

[0018] The horizontal ruler 1 and the vertical ruler 2 are made of stainless steel, which are strong and durable, and have good co...

Abstract

The invention, which relates to the financial products, discloses a worn banknote proportional contrast scale comprising a leveling ruler and a vertical ruler. A scale is marked on the horizontal ruler; and a pasting plate is pated on the leveling ruler. An end back plate is arranged at the vertical ruler vertically; a track rod is arranged at the side of the vertical ruler vertically; a casing tube sleeves the track rod; and a detection rod is arranged at the side of the casing tube vertically. With the provided scale, a worn banknote can be fixed conveniently and stably and can be measured precisely; the scale can be used conveniently; and the accuracy of the won banknote exchange can be guaranteed.

Description

Technical field [0001] The invention relates to the field of financial supplies, in particular to a ratio control ruler for residual money. Background technique [0002] In banks and other financial departments, it is often necessary to exchange some broken coins and damaged banknotes. According to relevant regulations on the exchange of broken coins, the exchange amount of broken coins needs to be based on the corresponding value of the total volume of broken coins relative to the volume of complete banknotes. That is to say, the value of the currency to be exchanged should be evaluated according to the size of the residual currency. However, the existing tool for measuring the volume of the residual currency is an ordinary ruler, which cannot fix the residual currency properly, and the measurement is not convenient enough, resulting in low accuracy of the residual currency exchange. Summary of the invention [0003] The technical problem to be solved by the present invention is...
