Description
The utility model relates to bank note purple light pick-up unit.
Existing bank note purple light detects and comprises two aspects: fluorescence labeling detects and the purple light reflection is strong and weak detects.Shown in Figure 1 is exactly an existing bank note purple light pick-up unit, include frame 103, support 104, purple light light source 101, photoresistance 102, truth identification level comparison circuit 105, counterfeit money warning circuit 106 etc., wherein, purple light light source 101, photoresistance 102 is fixed on the frame 103, and the position of purple light light source 101 is preceding, the position of photoresistance 102 after; Truth identification level comparison circuit 105, counterfeit money warning circuit 106 is arranged in the support 104.The upper surface of support 104, the part relative with purple light light source 101 forms detection platform 107.When carrying out the fluorescence labeling detection, bank note is placed on the detection platform 107, allow purple light shine on the fluorescently-labeled bank note, so, the fluorescence labeling of can't see at ordinary times can display, in the C scope of visual angle, can with the naked eye see, thus can by whether having the true and false that fluorescence labeling comes identification note on the identification bank note.And strong and weak detection of purple light reflection is according to true and false bank note the different characteristics of the degree of reflection of purple light to be detected.Bank note is put on the detection platform 107, allows purple light shine on the bank note, photoresistance 102 receives the purple light that bank note reflected, and detected light signal is transformed into electric signal, sends into truth identification level comparison circuit 105 then.Because genuine note is less to the reflection of purple light, counterfeit money is bigger to the reflection of purple light; Certain threshold level is set, and when finding counterfeit money, truth identification level comparison circuit 105 will produce electric signal, and input counterfeit money warning circuit 106, thereby gives the alarm.The detection of comprehensive above two aspects can identify the true and false of multiple bank note effectively.But in the existing bank note purple light pick-up unit, fluorescence labeling detects and the purple light reflection is strong and weak detects a shared purple light light source 101, and carries out on same detection platform 107.Have enough visual angle C, detection platform 107 all to be exposed to basically under the external environment condition in order to guarantee to carry out when fluorescence labeling detects, like this, purple light reflects strong and weak test section to be easy to be subjected to the influence of external light source and to cause that mistake surveys; In addition, because the variation of external environment, the strong and weak detection threshold of purple light reflection that also needs often to harmonize, sometimes even can can't finish detection because of exceeding range of adjustment.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and provides a kind of have high accuracy and stability, bank note purple light pick-up unit simple in structure.
For achieving the above object, the utility model has adopted following technical scheme: a kind of bank note purple light pick-up unit includes casing, division board, the purple light light source, photoelectric sensor, identification circuit etc., wherein, division board is fixed in the casing, and casing and division board surround a darkroom; The purple light that division board sends the purple light light source is divided into and is used for two parts that fluorescence labeling detected and be used for the strong and weak detection of purple light reflection, is used in the strong and weak purple light that detects of purple light reflection and shines in the darkroom, and photoelectric sensor is fixed in the described darkroom; Described darkroom has detection platform and leads to the opening of this detection platform, and described opening is fit to bank note and puts into.
The utility model has the advantages that, owing to increased division board, the strong and weak detection of purple light reflection carried out in the darkroom, thereby avoided the influence of extraneous light, improved the accuracy and the stability that detect greatly.Of the present utility model simple in structure, help applying.
Below in conjunction with drawings and Examples the utility model bank note purple light pick-up unit is described in further detail.
