Embodiment 1

[0014] In order to overcome the defect that the calculator in the prior art does not have the functions of weighing and banknote checking, the present invention provides a calculator with the functions of weighing and checking banknotes, such as figure 1 and 2 As shown, it includes a fuselage 1 and a built-in battery 9, and the fuselage 1 is provided with a weighing device and an ultraviolet money detector lamp 6, and the ultraviolet money detector lamp 6 is connected with the battery 9 through a switch 10 controlling it. Described ultraviolet money detector lamp 6 and switch are embedded in the side of fuselage 1.

[0015] The calculator provided in this embodiment has various functions, which brings convenience to people's life. The utility model has the advantages of small size, convenient portability, simple structure, reasonable design and practicability.

Embodiment 2

[0017] Such as figure 2 As shown, the weighing device includes a hook body 5, a gravity sensor 7, an amplifying circuit 8, an A / D converter 7 and a microprocessor 4, and the calculator also includes a display screen 11 and a built-in circuit board 2, so Described gravity sensor 7, amplifying circuit 8, A / D converter 3, microprocessor 4 and display screen 11 are connected with circuit board 2 respectively, and gravity sensor 7 is connected with microprocessor 4 through amplifying circuit 8, A / D converter 3 Connection, the microprocessor 4 is connected with the display screen 11, and the circuit board 2 is connected with the storage battery 9.

[0018] The hook body 5 passes through the fuselage 1, the hook body 5 is connected to the gravity sensor 7 arranged in the fuselage 1, the gravity sensor 7 is arranged between the lower side inner wall of the hook body 5 and the fuselage 1, and the amplifying circuit 8. The A / D converter 3 and the microprocessor 4 are arranged in the b...

Abstract

The invention provides a calculator with a weighing and currency detection function. The calculator comprises a machine body and a built-in storage battery and is characterized in that the machine body is provided with a weighing device and an ultraviolet ray currency detection lamp, wherein the ultraviolet ray currency detection lamp is connected with the storage battery through a switch for controlling the ultraviolet ray currency detection lamp. The calculator has the beneficial effects that: compared with the prior art, the calculator expands the functions of the calculator and adds the weighing device so as to bring convenience for people to weigh an object which needs to be weighed during consumption, in addition, the calculator also has a currency detection function, economic losscaused when people receive fake money during consumption is avoided, and the calculator has the advantages of small volume, convenience in carrying, simple structure, reasonability in design and practicality.

Description

technical field [0001] The invention specifically relates to a calculator with the functions of weighing and money checking. Background technique [0002] Nowadays, calculators are widely used, but the functions of existing calculators are relatively single, just simple calculation of numbers, which can no longer meet people's daily needs. When people buy some items that need to be weighed, such as rice, vegetables, etc., They may be deceived by the seller, and the items sold are short of catty and tael, and people cannot correct the catty on the spot because they did not have suitable weighing tools at the time, and they find out afterwards that they have been cheated but cannot claim for compensation. In addition, when people consume, they usually receive counterfeit money because they cannot distinguish money, resulting in economic losses. However, the existing money detectors are large in size and not easy to carry. The calculator is small in size and easy to carry, but...
