Fig. 9 is the light period time diagram of expression by the light period of the light emitting diode 6a～6h of the 7c of light emitting control portion control.The luminous one-period 14 of light emitting diode 6a～6h is by period 1 14a, constitute with continuous 14b second round of period 1 14a.Rotation test section 5c output motor pulse signal 15.Motor pulses signal 15 produces pulse 15a, 15b respectively in about 4msec cycle.Represent the luminous and time that bank note 2 is shone of light emitting diode 6a～6b with pulse signal 16～23 respectively.
Between light emission period between 16a～19a, promptly between time 24a (=1800 μ sec), accept the luminous of light emitting diode 6a～6d and be converted into electric signal by light-emitting diode 8a.In time 24a, common terminal 12e is connected with selection terminal 12f, and amplifier 9 is supplied with in the output of light-emitting diode 8a via amplifier 8d.
Then, between the terminal 600 μ sec of 19a between the distance light emission period, promptly between light emission period between the 20b, light emitting diode 6c is luminous.Then, between the terminal 400 μ sec of 20b between the distance light emission period, promptly make light emitting diode 6f luminous between light emission period between the 21b.
Between light emission period between 20b, the 21b, promptly between time 24b (=1000 μ sec), accept the luminous of light emitting diode 6e, 6f and be converted into electric signal by light-emitting diode 8b.In time 24b, common terminal 12c is connected with selection terminal 12g, and amplifier 9 is supplied with in the output of light-emitting diode 8b via amplifier 8e.
The total ascent time of the first identification sensor 12a and the second identification sensor 12b output signal is that time 24a and time 24b sum are 2800 μ sec.
Below, 14b second round is described.Second round 14b similarly between the about 600 μ sec of the starting point of distance pulse 15b, promptly between light emission period between the 16c, light emitting diode 6a is luminous.Then, between the terminal 400 μ sec of 16c between the distance light emission period, promptly between light emission period between the 17c, light emitting diode 6b is luminous, below, similarly, between the terminal 400 μ sec of 17c between the distance light emission period, promptly between light emission period between the 18c, light emitting diode 6c is luminous.Between the terminal 400 μ sec of 18b between the distance light emission period, promptly between light emission period between the 19b, light emitting diode 6d is luminous.
Between light emission period between 16c～19b, promptly between time 24c (=1800 μ sec), accept the luminous of light emitting diode 6a～6d and be converted into electric signal by light-emitting diode 8a.In time 24c, common terminal 12e is connected with selection terminal 12f, and amplifier 9 is supplied with in the output of light-emitting diode 8a via amplifier 8d.
Then, between the terminal 600 μ sec of 19b between the distance light emission period, promptly between light emission period between the 22d, light emitting diode 6g is luminous.Then, between the terminal 400 μ sec of 22d between the distance light emission period, promptly between light emission period between the 23d, light emitting diode 6h is luminous.
Between light emission period between 22d, the 23d, promptly between time 24d (=1000 μ sec), accept the luminous of light emitting diode 6g, 6h and be converted into electric signal by light-emitting diode 8b.In time 24d, common terminal 12c is connected with selection terminal 12h, and amplifier 9 is supplied with in the output of light-emitting diode 8c via amplifier 8f.
The total ascent time of the first identification sensor 12a and the 3rd identification sensor 12c output signal also is that time 24c and time 24d sum are 2800 μ sec.Consequently, to make light emitting diode 6a～6h carry out the needed time of luminous one-period be time after time 24a～24d sum promptly also will add between some adjustment on the 5600 μ sec to the 7c of light emitting control portion.The adjustment time is the required time of deviation before carrying that motor 5b stably works, that cause for the external environment condition that absorbs paper money identifier 1 etc.
As light period, for example, in period 1 14a, 17a, 18a, 19a, 21b are 400 μ sec between light emission period, and be relative therewith, and 16a, 20b are 600 μ sec between light emission period.That is, 16a, 20b grow 200 μ sec than 17a, 18a, 19a, 21b between light emission period between light emission period.Below, this reason is described.
In time between light emission period before the 16a, all light emitting diode 6a～6d that constitute the first identification sensor 12a are turned off the light, light-emitting diode 8a is the shading state.Equally, the time before light period 20b, all light emitting diode 6e, the 6f that constitutes the second identification sensor 12b turned off the light, light-emitting diode 8b is the shading state.
14a compares with the period 1, and 14b uses the 3rd identification sensor 12c to replace the second identification sensor 12b in second round.Therefore, 14a is identical with the period 1, and in the time between light emission period before the 16c, all light emitting diode 6a～6d that constitute the first identification sensor 12a turn off the light, and light-emitting diode 8a is the shading state.Similarly, in the time between light emission period before the 22d, all light emitting diode 6g, 6h of constituting the 3rd identification sensor 12c turn off the light, and light-emitting diode 8c is the shading state.
Like this, light emitting diode 6a～6h carry out periodicity luminous before, when light emitting diode 6a～6h all turned off the light, official hour was stablized, is needed in luminous at first light emitting diode 6a, 6e, the luminous output of 6g in light emitting diode 6a～6h that light- emitting diode 8a, 8b, 8c accept to comprise among same identification sensor 12a～12c.
Figure 10 is the time diagram that is illustrated in the action of the first identification sensor 12a in the period 1 14a.In time 24a as shown in figure 10, common terminal 12e is connected with selection terminal 12f, and selects light-emitting diode 8a.From the waveform 25 of the signal of amplifier 8d output as shown in figure 10.In addition, waveform 25 as shown in figure 10 is situations that standard bank note after the printing of the hypothesis maximum deep or light difference that will implement to be equivalent to true bank note 2a is transported to path 4.
16a between light emission period, before 16a between light emission period, light emitting diode 6a～6d all turns off the light.Therefore, the waveform 25 from the signal of light-emitting diode 8a output begins to raise from zero level.Therefore, before the waveform 25a via amplifier 8d output reaches stable point, need the time of 600 μ sec.
Relative therewith, 17a between light emission period is having 16a between light emission period before the 17a between light emission period, and light-emitting diode 8a is the incident state.Therefore, the output from light-emitting diode 8a raise in the light period 16a stage.According to this situation, the time that will reach stable point via the waveform 25b of amplifier 8d output shortens to 400 μ sec.Similarly, 18a between light emission period is also having 17a between light emission period before the 18a between light emission period, and light emitting diode 8a is the incident state.Therefore, the time that will reach stable point via the waveform 25b of amplifier 8d output shortens to 400 μ sec.Similarly, also there is 18a between light emission period in 19a between light emission period before the 19a between light emission period, and light emitting diode 8a is the incident state.Therefore, the time that will reach stable point via the waveform 25d of amplifier 8d output shortens to 400 μ sec.
As mentioned above, from the state that light emitting diode 6a, 6b, 6c, the 6d that constitutes the first identification sensor 12a all turns off the light, make light emitting diode 6a luminous at first.Therefore, the luminous output of carrying out luminous light emitting diode 6a until the acceptance of light-emitting diode 8a at first is stable, requires to make the fluorescent lifetime of light emitting diode 6a elongated.
The optical signature information of the bank note 2 that obtains like this is admitted to identification part 10 via amplifier 9.In the identification part 10, the true and false and the Currency Type of bank note 2 are judged.Will be in the result after identification part 10 is judged from lead-out terminal 11 outputs.
But in so existing paper money identifier 1, for example, as shown in figure 10, before pulse 15a, the light emitting diode 6a～6d that constitutes identification sensor 12a all ends, and light emitting diode 8a is the shading state.Therefore, before the fluorescent lifetime that makes initial luminous light emitting diode 6a is stable, must prolong fluorescent lifetime.Consequently, be difficult to read at a high speed, to high-density the optical signature of bank note 2.
Summary of the invention
The invention provides a kind of paper money identifier, it can read the optical signature of bank note at a high speed, to high-density.
Paper money identifier of the present invention has: delivery section, a plurality of light-emitting component, light emitting control portion, photo detector, the identification part of carrying bank note.Light-emitting component sends the light that bank note is shone.Light emitting control portion controls the luminous of a plurality of light-emitting components.The light that photo detector is accepted the self-emission device irradiation and passed bank note or reflect, and output signal.The identification part is discerned the true and false of bank note according to the signal of photo detector output.Moreover, it is luminous that light emitting control portion carries out a plurality of light-emitting components successively, and, before the light-emitting component that uses for the true and false of identification part identification bank note is luminous, make the light-emitting component different carry out luminous in advance with the light-emitting component that uses for the true and false of discerning bank note.By this structure, provide a kind of and can shorten the paper money identifier that the signal of exporting from photo detector reaches the stable time and can read the optical signature of bank note at high speed.

Between light emission period between 53b, 54b, 51c, the 52c, promptly between time 59c (=1400 μ sec), accept the luminous of light emitting diode 46a～46d and be converted into electric signal by light-emitting diode 47a.In time 59c, common terminal 36e is connected with selection terminal 36f, and via amplifier 47d amplifier 39 is supplied with in the output of photo detector 47a.
Below, the luminous of sensor 36c in the second round 48b described.Light emitting diode 46g 57d between light emission period carry out luminous before, 36a is same with sensor, light emitting diode 46h conducting between 300 μ sec.That is, between pre-light emission period between the 58c, light emitting diode 46h carries out luminous in advance.Apart between the terminal 400 μ sec of 58c between pre-light emission period, promptly between light emission period between the 57d, light emitting diode 46g is luminous.Afterwards, light emitting diode 46h carry out between the 58d between light emission period luminous.Moreover, light emitting diode 46h in order to prepare next cycle 48 between light emission period 58d continuous, until the terminal of 48b second round, promptly proceed between the 58e between pre-light emission period luminous in advance.That is, it is 58e sum between 58d and pre-light emission period between light emission period that light emitting diode 46h carries out during luminous, and 58e equals second and adjusts time 60b between pre-light emission period.
Between light emission period between 57d, the 58d, that is, between time 59d (=700 μ sec), accept the luminous of light emitting diode 46g, 46h and be converted into electric signal by light-emitting diode 47c.In time 59d, common terminal 36e is connected with selection terminal 36h, and via amplifier 47f amplifier 39 is supplied with in the output of photo detector 47c.
Second round, 48b and period 1 48a were same, and fluorescent lifetime signal 51 and the fluorescent lifetime signal 57 exported from the 42c of light emitting control portion are same signal, and use common control signal.In addition, fluorescent lifetime signal 52 and fluorescent lifetime signal 58 are same signal, and use common control signal.That is, the 42c of light emitting control portion controls jointly to each light emitting diode 46a, 46b, 46g, the 46h that constitutes a plurality of sensor 36a, 36c.That is, the 42c of light emitting control portion uses common control signal that a plurality of light emitting diode 46a, the 46g that constitutes a plurality of sensor 36a, 36c controlled.Equally, the 42c of light emitting control portion also uses common control signal that a plurality of light emitting diode 46b, the 46h that constitutes a plurality of sensor 36a, 36c controlled.Thus, can realize the economy of software that the 42c of light emitting control portion is controlled and autoluminescence control part 42c economy to the wiring of light emitting diode 46a, 46b, 46g, 46h.
As mentioned above, paper money identifier 31 is discerned the 62 needed times of bank note, is that one-period 48 is summations of needed time of period 1 48a and needed time of 48b second round.In addition, the needed time of period 1 48a is the summation that time 59a and time 59b sum and continuous therewith some first are adjusted time 60a.The needed time of 48b second round is the summation that time 59c and time 59d sum and continuous therewith some second are adjusted time 60b.That is, it is 4200 μ sec that bank note 62 is discerned the needed time, compares with the time (removing the adjustment time is 5600 μ sec) that needs at existing paper money identifier, can shorten the i.e. 1400 μ sec of suitable one-period 48.
Like this, because identification is that one-period 48 usefulness 4200 μ sec finish the 62 needed times of bank note, thereby be under the situation of 200mm/sec in the transporting velocity of bank note 62, just can be in the optical signature that reads bank note 62 every 0.84mm at interval.That is, the motor pulses signal of being exported at motor pulses signal generation 34e 50 is under the situation of 3msec, period 1 48a and second round 48b be respectively 3ms, be that one-period 48 is exactly 6msec with their reading of lumping together.Consequently, reading of bank note 62 is spaced apart 1.2mm.That is, energy high speed and high density read the optical signature of bank note 62.
In addition, in the present embodiment,, 400 μ sec and 300 μ sec have been used alternately as fluorescent lifetime separately.But also can be 300 μ sec with all fluorescent lifetime unifications.Under this situation, the 48 needed times of one-period will shorten 600 μ sec again.
In addition, as shown in Figure 4, the part in the band dashed circle accept the light that light-emitting component 46a～46h sends by light-emitting diode 47a～47c, and the electric signal after will changing outputs to amplifier 39.Use the identification of the electric signal execution bank note 62 of this output.In addition, the part of band oblique line is represented to be used to shorten between one-period 48 light emission period that contains pre-lighting function of required time.
As mentioned above, that a plurality of light emitting diode 46a～46h are carried out successively is luminous for the 42c of light emitting control portion.Meanwhile, before the light emitting diode 46c, the 46e that use for the true and false of identification part 40 identification bank note 62,46g luminous, make light emitting diode 46b, 46f, the 46h different luminous in advance with light emitting diode 46c, the 46e, the 46g that use for the true and false of discerning bank note 62.Thus, can shorten the time of the one-period 48 of identification.
