Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
This cash inspecting machine: profile is stepped, and housing is by loam cake 21, base 23, and benchmark baffle plate 24 and backboard 10 are formed, and 23 of loam cake 21 and bases leave a finedraw 22; Enclosure interior is provided with testing circuit, and testing circuit is made up of detection light source 19, photoreceiver 2, two electric signal sampling holders 4,5, monostalbe trigger 7,8, divider 6, comparer 16, positioning circuit and warning circuits; Its characteristics are: photoreceiver 2 faces detection light source 19, detection light source 19 is by analog switch 1 control, the output terminal of photoreceiver 2 is by filter amplifier 3 and two electric signal sampling holders 4,5 input end links to each other, monostalbe trigger 7,8 output terminal and electric signal sampling holder 4,5 control end links to each other, two electric signal sampling holders 4,5 output terminal links to each other with the input end of divider 6 respectively, the input end of comparer 16 and the output terminal of divider 6 link to each other, another input end connects stabilivolt 11, the stabilivolt other end 11 ground connection, the output terminal of comparer 16 connects the analog switch 9 of warning circuit, warning circuit connects light emitting diode 20 by analog switch 9 and constitutes light emitting diode 20 minus earths; The control end of analog switch 9 connects the optoelectronic switch 14 of positioning circuit; Positioning circuit is made up of four reflections or transmission-type optoelectronic switch 12,13,14,15, optoelectronic switch 12,13 links to each other with the input end of monostable trigger 7,8 respectively, optoelectronic switch 14 is connected to analog switch 1 control end and analog switch 9 control ends simultaneously, and optoelectronic switch 15 links to each other with the control end of analog switch 1.
Photoreceiver 2 is photoelectric cells.
Here positioning circuit adopts four optoelectronic switches that separate transmission-type, is received by four pairs of infrared emission pipe is formed, and detection light source 19 is the infrared laser diode.Infrared light is beaten in the infrared fluorescence district and is produced green-yellow light, is close to an optical filter in the photoelectric cell front, makes yellowish green luminous energy see through, and infrared light can not see through.Then have green-yellow light to produce if infrared light is beaten in the infrared fluorescence district like this, beating when non-phosphor region does not then have.When photoelectric cell converts these light signals to electric signal, very big difference is just arranged, judge the true and false of Renminbi by the size that detects phosphor region and non-phosphor region difference.When check, Renminbi 17 faces up, minor face enters from finedraw along benchmark baffle plate 24, when Renminbi 17 arrived optoelectronic switch 15, the low level of generation made analog switch 1 closure, has opened infra-red laser diode 19, when arriving optoelectronic switch 12, this moment, 19 dozens of infrared laser diodes were on the non-logo area of Renminbi 17, and optoelectronic switch 12 produces level to be changed, and samples by monostalbe trigger 7 control sampling holders 4.When arriving optoelectronic switch 13, this moment, 19 dozens of infrared laser diodes were on the logo area of Renminbi 17, optoelectronic switch 13 produces level to be changed, sample by monostalbe trigger 8 control sampling holders 5, and these two electric signal all remain unchanged, sending into divider 6 back of being divided by compares at 16 li of comparers and the value V that set, when Renminbi 17 arrives optoelectronic switch 15, the signal of two collections is stable, the level that produces is closed infrared laser diode 19, analog switch 9 closures are connected warning circuit simultaneously, the comparative result of reflection comparer.Here report to the police with light emitting diode 20, if counterfeit money then light emitting diode 20 light.Make like this 19 of infrared laser diodes when detecting in case of necessity between in work, it is also safer not only to reduce power consumption.
Several optoelectronic switches are installed in appropriate location in the shell of the first half, position according to infrared anti-false sign on the Renminbi, and this installs photoreceiver and testing circuit in the housing of the latter half in the relevant position.Wherein the left side of shell is a benchmark baffle plate 24, Yi Bian Renminbi wherein pasting benchmark baffle plate 24, enter from finedraw 22, in the time can not entering again, Renminbi is extracted out, finish detection.In the relevant position of loam cake detection light source and optoelectronic switch are housed, face the light source place at base a photoreceiver is housed, if photoswitc is to separate transmission-type, receiving unit is equipped with in the place that faces the radiating portion of loam cake.The part optoelectronic switch is opened light source automatically when Renminbi is put into, close automatically when detection is finished.Can when forgetting the pass power switch, drop to power consumption minimum like this.Here because only use a light source and photoreceiver, can not gather the electric signal that light source anti-false sign district and non-logo area are converted to by reflection or transmitted light simultaneously, so adopt sampling hold circuit adopt earlier electric signal maintain, when two electric signal have all been gathered, these two value of electrical signals are divided by, compare by comparer and preset threshold again.This threshold value is passed through various newness degrees, and the different Renminbi of stained degree Renminbi measures.Result relatively sends into warning circuit, if counterfeit money can carry out sound and light alarm.Level by optoelectronic switch changes can be known and will detect logo area and whether non-logo area has arrived position of detector.
