Technical field

The utility model is relevant with the checkout equipment of Renminbi anti-counterfeiting characteristic, relates to a kind of magnetic ink testing agency that is used for Renminbi.

Background technology

The insider knows that the state-of-the-art Swiss franc that surely belongs to of banknote anti-counterfeiting technology be we can say in the world, the great achievement of the advanced anti-counterfeiting technology in the Swiss franc collection world.

China's quadruplet Renminbi has just been used for reference the anti-counterfeiting technology of Swiss franc, has adopted ten multinomial false proof designs altogether.One of them is exactly to be provided with magnetic ink in some ad-hoc location and the zone of Renminbi.

And existing paper money counter is approved product mostly, does not possess the detection of dynamic function to above-mentioned magnetic ink fully.

Summary of the invention

The purpose of this utility model is to provide a kind of magnetic ink testing agency that is used for Renminbi; utilize the feature of the magnetic ink regularity of distribution on the quadruplet Renminbi; detect the position and the zone at magnetic ink place by the magnetoresistive magnetic head that is provided with; accurately differentiate the true and false of Renminbi, flow into society with control abnormity currency (counterfeit money).

The purpose of this utility model is achieved in that

The magnetic ink testing agency that is used for Renminbi is arranged between the currency feeding mechanism and cash-out machine structure of paper money counter; Comprise several money pressing wheels of being located on the paper money counter press-note wheel shaft, be located in paper money counter to about on the runner shaft two to runner; One end of described press-note wheel shaft wears a code-disc, and code-disc is provided with a secondary code-disc to pipe; Its substantive distinguishing features is:

Described press-note wheel shaft and between the runner shaft, be provided with at least two secondary penetration infrared emission counting optocouplers and the infrared count pick up optocoupler of penetration, at least three magnetoresistive magnetic heads, the magnetic head pinch roller of corresponding setting with magnetoresistive magnetic head is located on the described press-note wheel shaft;

Described press-note wheel shaft, the center line of the center line of runner shaft and penetration infrared counting optocoupler, magnetoresistive magnetic head is coexisted in the vertical plane.

The above-mentioned magnetic ink testing agency that is used for Renminbi, wherein, described magnetoresistive magnetic head is provided with at interval with respect to described penetration infrared emission, count pick up optocoupler.

The utility model is used for the magnetic ink testing agency of Renminbi owing to adopted above-mentioned technical scheme, makes it compared with prior art, has following advantage and good effect:

Because the utility model is the testing agency that sets up between the currency feeding mechanism of original paper money counter and cash-out machine structure, when tested currency passes through this testing agency, need not directly to contact with tested currency, a code-disc and a secondary code-disc on utilizing the two secondary penetration infrared emission, count pick up optocoupler and the magnetoresistive magnetic head that are provided with in this mechanism and magnetic head pinch roller and being arranged on the press-note wheel shaft match to pipe, under the control of cpu chip, can detect the position and the zone at magnetic ink place, with the true and false of accurate differentiation Renminbi.

Therefore, the utility model can be realized the detection of dynamic to the Renminbi magnetic ink in the dynamic process of counting, and therefrom accurately rejects suspicious currency.

Description of drawings

Embodiment by the following magnetic ink testing agency that the utility model is used for Renminbi can further understand its practical novel purpose, specific structural features and advantage in conjunction with the description of its accompanying drawing.Wherein, accompanying drawing is:

Embodiment

Shown in Fig. 1,2,3,4, the magnetic ink testing agency that the utility model is used for Renminbi is arranged between the currency feeding mechanism and cash-out machine structure of paper money counter, mainly comprise several money pressing wheels 1 of being located on the paper money counter press-note wheel shaft 10, be located in paper money counter to about on the runner shaft 11 two to runner 3; One end of press-note wheel shaft 10 wears a code-disc 6, and code-disc 6 is provided with a secondary code-disc to managing 7.

At press-note wheel shaft 10 and between to runner shaft 11, be provided with the infrared count pick up optocoupler of at least two secondary penetration infrared emission counting optocouplers 2 and penetration 4, at least three magnetoresistive magnetic heads 9, be located on the press-note wheel shaft 10 with the magnetic head pinch roller 8 of magnetoresistive magnetic head 9 corresponding settings.In the present embodiment, three magnetoresistive magnetic heads 9 are provided with at interval with respect to penetration infrared emission, count pick up optocoupler 2,4.

From Fig. 2, be not difficult to find out, press-note wheel shaft 10 of the present utility model, the center line of the center line of runner shaft 11 and penetration infrared counting optocoupler 2,4, magnetoresistive magnetic head 9 coexisted in the vertical plane.Like this, can guarantee that penetration infrared counting optocoupler 2,4, magnetoresistive magnetic head 9 can synchronous workings, the situation of unlikely generation omission or flase drop.

Referring to Fig. 5, the course of work of the utility model testing agency is roughly as follows:

On the smooth money-supplying board that is placed on the paper money counter currency feeding mechanism of tested currency 5, drive money pressing wheel 1 behind the electric motor starting, runner 3 rotated, make tested currency 5 be folded in rubber money pressing wheel 1 and between the runner 3, and with certain speed along the B among Fig. 3 to operation.Utilize the signal of two secondary penetration infrared counting optocouplers 2,4 to send into cpu chip, judge whether tested currency 5 enters in the measured zone.

Cpu chip is according to the feedback signal of this two secondary penetration infrared emission, count pick up optocoupler 2,4, control setting on press-note wheel shaft 10 code-disc 6 and a secondary code-disc to managing 7, measure the width of tested currency 5.Cpu chip utilizes counter to gather this signal, simultaneously, when tested currency 5 is in the measured zone, the magnetic signal of cpu chip control magnetoresistive magnetic head 9, the micro-signal that magnetoresistive magnetic head 9 is collected amplifies, filtering, correction, relatively wait a series of processing, and converting magnetic signal to digital signal by the A/D analog to digital converter, cpu chip utilizes the timer acquired signal again, and then the signal that is collected is stored.

By calculated signals and judgement, can accurately differentiate the true, doubtful of tested currency 5 to tested currency 5.

If tested currency 5 is judged as doubtful coin, then paper money counter quits work and with buzzer warning, shows the number of tested currency 5 simultaneously.
