When the surface of bank note 2 made progress, fluorescence showed ultraviolet ray excited and luminous by from light emitting diode 5, and phototransistor 6 detects fluorescence and shows.
The surface of bank note 2 is downwards the time, and fluorescence shows ultraviolet ray excited and luminous by from light emitting diode 7, and phototransistor 8 detects fluorescence and shows.
Control part 15 is connected to light emitting diode 5 and 7.In addition, control part 15 is controlled carrying device 4 via drive division 17.
Phototransistor 6 and 8 output are connected to identification part 12 via linear amplifier 9, logarithmic amplifier 10 and A/D transducer 11.Identification part 12, the reference data that the output and the storer 13 of A/D transducer 11 are stored compares, the true and false and the denomination of identification bank note.Terminal 14 output recognition results.
But, above-mentioned paper money identifier in the past, owing to use 2 groups of light emitting diodes and phototransistor, so have the problem of miniaturization and cost degradation difficulty.
In addition, as the conventional art that the present invention relates to, known have: the flat 10-3561 communique of Japanese Patent Application Laid-Open for example.
Summary of the invention
Paper money identifier of the present invention is the paper money identifier that the bank note that simultaneously has the fluorescence demonstration is discerned, comprising: the insertion mouth of bank note; The path of conveyance bank note; The carrying device of conveyance bank note; Be arranged at the light emitting diode of path top; Be arranged at the light receiving element corresponding of path below with light emitting diode; Carry out the identification part of paper money recognition with the signal of exporting based on light receiving element.
At this, fluorescence shows that the purple light that is radiated for the fluorescence that detects bank note shows by light emitting diode excites and send sodium yellow, and described purple light wavelength is 390～420nm except that ultraviolet light, sees through bank note in the fluorescence display part of bank note.Purple light and sodium yellow can pass through bank note together.Photodiode detects sodium yellow and output signal.The true and false of bank note is discerned in the identification part based on the signal of photodiode output.When the surface of bank note makes progress, the purple light fluorescence excitation of light emitting diode radiation shows, sodium yellow is sent in the fluorescence demonstration, light receiving element detects the sodium yellow that sees through bank note, when the surface of bank note is downward, the purple light of light emitting diode radiation sees through bank note and the fluorescence excitation demonstration, and sodium yellow is sent in the fluorescence demonstration, and light receiving element detects sodium yellow.
Paper money identifier of the present invention, owing to only use 1 group of light emitting diode and photodiode, so can realize miniaturization and low cost.

Fig. 1 is the block diagram of paper money identifier of the present invention;
Fig. 2 is the figure on the surface of expression bank note;
Fig. 3 is the family curve of the light transmission rate of bank note;
Fig. 4 is the block diagram of paper money identifier in the past.
Embodiment
Fig. 1 is the block diagram of paper money identifier of the present invention.Fig. 2 represents the surface of bank note 20.The surface of bank note 20 has fluorescence and shows 16.
In Fig. 1, the insertion mouth 21 of bank note 20 is connected to path 23.Carrying device 24 has pulley (pulley) and synchronous belt (timing belt).
The light emitting diode 25 of radiation purple light is arranged at the top of path 23.The below that will relatively be arranged at path 23 as the photodiode 26 and the light emitting diode 25 of light receiving element.Bank note 20 is walked between light emitting diode 25 and photodiode 26.
The output of phototransistor 26 is connected to identification part 30 via linear amplifier 27, logarithmic amplifier 28 and A/D transducer 29.
The storer 32 that stores the reference data of bank note 20 is connected to identification part 30.Though show among the figure that identification part 30 is built-in with: the comparer of the output of comparison A/D transducer 29 and the reference data of bank note 20; The determining device that connects the output of this comparer.The output of determining device is connected to lead-out terminal 31.
33 pairs of drive units 34 that drive carrying device 24 of control part are controlled.Control part 33 is also controlled lighting of light emitting diode 25.
Below, the action of the paper money identifier of above structure is described.Be inserted into and insert mouthfuls 21 bank note 20, by carrying device 24 along path 23 and by conveyance.Drive unit 34, the speed of carrying out a paper money recognition with per second drives carrying device 24.
When the surface of bank note 20 made progress, the purple light fluorescence excitation of light emitting diode 25 radiation showed 16, and fluorescence shows that 16 send sodium yellow.Phototransistor 26 detects the sodium yellow that sees through bank note 20.
When the surface of bank note 20 was downward, the purple light of light emitting diode 25 radiation saw through bank note 20 and fluorescence excitation demonstration 16.Fluorescence shows that 16 send sodium yellow, and phototransistor 26 detects sodium yellow.
Under the situation, sodium yellow all is transformed to electric signal by photodiode 26, is input to identification part 30 via linear amplifier 27, logarithmic amplifier 28 and A/D transducer 29 arbitrarily.
Fig. 3 represents the family curve 43 of the light transmission rate of bank note 20.
Paper money identifier of the present invention is owing to use to see through the purple light of bank note 20, so as above-mentioned illustrated, no matter the surface of bank note 20 can both be detected the fluorescence demonstration of bank note 20 by 1 group of light emitting diode 25 and photodiode 26 upwards still downwards.What in addition, can fluorescence excitation show is the purple light (light of the wavelength below 390～420nm).
But, because the light transmission rate (10%) of the light transmission rate (4%) of purple light and sodium yellow is different, so different determinating references is used up and down according to the surface of bank note 20 in identification part 30 when the true and false of discerning bank note 20 and denomination.The surface of bank note 20 upwards still downwards, is judged based on the characteristic of bank note 20.
Because the light transmission rate about 4% of purple light is a small-signal, logarithmic amplifier 28 can amplify the signal of purple light effectively.
In addition, and the purple light of light emitting diode 25 radiation (390～420nm), owing to be visible light (between 380nm～810nm), so can whether normal by visual if differentiating light emitting diode 25.Therefore, the maintenance of device is easy.
Aforesaid the present invention can provide the small-sized paper money identifier cheaply that only uses 1 group of light emitting diode and photodiode.Paper money identifier of the present invention for example can be used for automatic vending machine.
