Description

Mother matrix surface detecting method and device, mother matrix class detecting device and printing equipment

Technical field

[0001]

The present invention relates to comprise the printing equipment of mother matrix table/back side detection method, mother matrix table/back side sniffer, mother matrix class detecting device and hole plate print device etc.

Background technology

[0002]

Now, as easy mode of printing, known have a digital plate for thermal sensitive porous printing.This is based on the image information of reading computer outputs such as view data or personal computer from original image, with heat is first-class will be as thermosensitive porous plate printing mother matrix (following only be called " mother matrix ") the fusion perforation of printing with version, the mother matrix that plate-making is finished is wrapped in its peripheral part and is provided with the device that prints on edition housing outer peripheral face of printing cylinder of the cylindric version of porous housing.Below, the version housing only is called " printing cylinder ".

Supply with printing ink with the inking parts that are located at printing cylinder inside to version housing inner peripheral surface, by compressing parts printing is pressed on the printing cylinder with pressure roller etc., printing ink is oozed out by the perforated portion of mother matrix and transfers on the printing, so, on printing, form ink image.

[0003]

As mother matrix, known have at thermoplastic resin film (following only be called " film ") upward with the structure (hereinafter referred to as " common mother matrix ") of binding agent applying as the porous fiber film of the porous support of printing ink trafficability characteristic.As the porous fiber film, the general flaxen fiber that is called as the Japan paper fiber or the fiber synthetic of using with flaxen fiber, or with the mixed fiber of lumber fibre.

; in the mother matrix of this structure; there is the porous support that constitutes by fiber owing on film, be close to film; on the part of overlapping fiber and part that film is connected; binding agent is agglomerated into the palama shape in a large number; be difficult to carry out have the problem of the irregular grade of generation printing in this part formation by a heat perforation that produces.

[0004]

In order to eliminate such problem, open in the flat 10-236011 communique the spy and to have proposed the thermosensitive porous plate printing mother matrix, wherein, the stacked porous resin film that constitutes by resin on the face of thermoplastic resin film one side, the stacked porous fiber film that constitutes by the fibrous material that mutually combines on this porous resin film.

So-called porous resin film is that the resin that is dissolved in solvent is separated out, by the porous film of formation such as condensing.So-called porous fiber film, be use that tissue paper that the synthetic fibers material by the strings of cotton, fiber crops etc., polyester, polyvinyl alcohol etc. constitutes etc. forms, bonding mutually by fibrous matter, twine and stumble or film that braiding etc. is combined into.

According to the thermosensitive porous plate printing mother matrix of this structure, can eliminate the problem of the irregular grade of above-mentioned printing, and the stiffness of mother matrix and hot strength are improved, picture quality also is improved.

[0005]

When the thermosensitive porous plate printing mother matrix that will have a porous resin film is arranged in the plate-making portion of hole plate print device, when its surface and back side dress inverse time, can make on the heater element of heat head facing to the porous fiber film of film opposition side, cause plate-making bad.

[0042]

As shown in Figure 5, the structure of the mother matrix 10 of Shi Yonging in the present embodiment, be on the face of thermoplastic resin film 11 1 sides, the stacked porous resin film 12 that constitutes by thermoplastic resin and as the 3-tier architecture of the porous fiber film 13 of the porous support that constitutes by the fibrous material that mutually combines.Moreover the porous support is also referred to as porous membrane.

Porous resin film 12 is made of resin molding inscape 12a and space 12b.The structure of porous resin film 12 is: owing to by making the resin that is dissolved in solvent separate out, condense and wait mode to form, contain numerous space 12b on the inside and the surface of film.

Consider the trafficability characteristic of printing ink, preferably can do like this: space 12b is continuous on the thickness direction in film, and if with thermoplastic resin film 11 as the bottom surface, then space 12b connects on the end face direction.

[0043]

As the resin of the main component of the material that constitutes porous resin film 12, use the resin that is recorded in the paragraph " 0035 " that above-mentioned spy opens the 2002-362057 communique.In the resin solution of the manufacturing process of porous resin film 12, also can add filler in case of necessity.This interpolation also can bring influence to the size in the shape of the porous resin film that generates, intensity, aperture in dry run.Specifically, be the inorganic matter of zinc oxide, titanium dioxide, calcium carbide, silicon etc., the organic polymer particles of polyvinyl acetate, polychlorostyrene ethene, polyacrylic acid methyl etc.Also can effectively utilize microcapsules, MATSUMOTO microballoon (Matsumoto Yushi-Seiyaku Co., Ltd.'s system).

[0046]

Then, with reference to Fig. 4, just survey the surface of mother matrix 10 and the mother matrix table/back side sniffer 23 at the back side and describe in detail.Shown in the chain-dotted line among Fig. 4, mainly by constituting with lower member, these parts are mother matrix table/back side sniffer 23: scanning, the surface of surveying mother matrix 10 or the single optical sensor 20 at the back side; Formation makes the mother matrix of the above-mentioned moving-member that mother matrix 10 moves send motor 5 and belt hold roller 3 to respect to optical sensor 20; Input about by the output signal at the surface of optical sensor 20 detected mother matrixs 10 or the back side promptly from the detection voltage of sensor 20, to carry out the specialized hardware 24 that signal described later is handled; Send motor 5 to by mother matrix, the LCD display part 47 of guidance panel 40 and plate-making control part 21 are controlled hot 2 action, and judge the table/back side decision means 28 of mother matrix 10 according to the difference of the detection voltage of importing from specialized hardware 24.

Automatic platemaker 1 has mother matrix table/back side sniffer 23.Here, so-called " automatic platemaker 1 has mother matrix table/back side sniffer 23 " is that specialized hardware 24 and the decision means 28 of saying the control structure major part described later of mother matrix table/back side sniffer 23 not necessarily is located in the automatic platemaker 1, also comprise such situation: connect, be configured on electric by holding wire or electric wire on the control substrate in the device body 50 of being located at automatic platemaker 1 outside etc., belong to automatic platemaker 1 in fact.

[0047]

Optical sensor 20 is connected on electric on the specialized hardware 24 by holding wire.As optical sensor 20, more particularly, consider preferably to use infrared ray sensor from following some factor, these factors are: mother matrix 10 non-leuco transparent whites as described above (hereinafter referred to as white) of Shi Yonging in the present embodiment, and infrared light can not bothered human eye; Compare with the LED of visible light, luminous power output is big; Approach the sensitivity wavelength of the phototransistor etc. of photo detector one side.

The optical sensor 20 that is made of infrared ray sensor is provided with: light-emitting component, by generating infrared ray (for example infrared light of wavelength 905nm) and constituting to penetrating ultrared LED as the surface of the mother matrix 10 of detected object or the back side; And photo detector, constitute corresponding to this catoptrical voltage and as the phototransistor that detects voltage output by receiving from the surface of mother matrix or reverberation, the amplification at the back side.

In optical sensor 20, owing to use above-mentioned infrared ray sensor, optical sensor 20 is irrelevant with color, corresponding to the concentration (brightness) of mother matrix, will amplify and output from photo detector according to the detection voltage corresponding to the light reflectivity (light volume reflection) of black and white concentration.Here illustrate: for the ultrared reactant from the light-emitting component outgoing of optical sensor 20 is not color, but the reverberation identical with the situation of mother matrix 10 non-coloring, white is back to the concentration of photo detector, corresponding blueness or redness etc. colored reactionless, therefore, in optical sensor 20, can not carry out the identification of color.

[0048]

Specialized hardware 24 mainly is made of following parts, and they are: will be transformed into the A/D converter 25 of digital value from the analog detection magnitude of voltage (output signal value) of optical sensor 20; As register 26 with the temporary transient holding member that keeps of the digital value after the conversion; And calculate the arithmetic unit 27 remain on the digital value in the register 26 and to obtain poor (output signal value poor) that detect voltage etc.Arithmetic unit 27 is made of for example subtraction circuit.Moreover above-mentioned holding member can be RAM.

Specialized hardware 24 is connected electrically to decision means 28 by holding wire.The difference of the detection voltage of calculating with the arithmetic unit 27 of specialized hardware 24 is input to decision means 28.

[0049]

Decision means 28 is made of the microcomputer that comprises CPU, ROM, RAM, I/O interface etc.Above-mentioned CPU also has the control function except calculation function.Decision means 28 has following function, promptly according to the operation program and the relation data that from above-mentioned ROM, access, judge the table/back side of mother matrix 10 from the difference of the detection voltage of input, send the LCD display part 47 of motor 5, guidance panel 40 and 21 pairs of heat heads of plate-making control part to by mother matrix and carry out as described later controls.

In addition, decision means 28 has by specialized hardware 24, and is interrupted (dispersing) to the function of the difference of the detection voltage of obtaining above-mentioned a plurality of positions from the detection voltage sampling (sampling) of optical sensor 20.Decision means 28 is not limited to above-mentioned sampling intermittently and obtains the function of difference, also has by specialized hardware 24 continuously to the function of the difference of the detection voltage of obtaining above-mentioned a plurality of positions from the detection voltage sampling of optical sensor 20.

In the above-mentioned ROM of decision means 28, deposit in by mother matrix and send the LCD display part 47 of motor 5, specialized hardware 24, guidance panel 40 and operation program and the relation data that plate-making control part 21 is controlled heat 2 to, this operation program and relation data are suitably accessed by the above-mentioned CPU of decision means 28.The RAM of decision means 28 has the function with the temporary transient storage of result of calculation of above-mentioned CPU.

[0050]

In control structure shown in Figure 4, because the detection voltage that sends from optical sensor 20 is the analogue value, consider the arithmetic unit 27 in The noise and the post processing, it is comparatively favourable to be transformed into digital value.The A/D conversion that detects the sampled data of voltage also can be used the analog input of the above-mentioned CPU of decision means 28, if consider processing speed and load, then to be implemented as by specialized hardware.

Therefore, if not too take in good for processing speed or load, then also can remove the register 26 and the arithmetic unit 27 of specialized hardware shown in Figure 4 24, on the input port of the decision means 28 that can be described as control device one side that possesses micro-computer architecture, be electrically connected optical sensor 20, carry out the processing same with register 26 and arithmetic unit 27 in decision means 28 sides.

[0051]

Moreover, be not limited to control structure shown in Figure 4, for example, also can be connected with decision means 28 with receiving and dispatching, control the action of sending motor 5 in above-mentioned main control unit side with the main control unit (main control unit: not shown) of the integral body of the control object driver part of each device/part of control hole plate print device shown in Figure 1 (referring to actuator) as the motor of controlling object and solenoid etc.That is, also can utilize the initiating signal that button 41 is started in the plate-making of guidance panel 40 as triggering signal, the order when moving according to above-mentioned plate-making, the rotation that the control mother matrix is sent motor to drives, make optical sensor 20 actions, necessary range sweep is done at the surface and the back side of mother matrix 10.

[0052]

Then, referring to figs. 1 through Fig. 6, the action of mother matrix table/back side sniffer 23 is described.

Connect (ON) to the power switch (not shown) that each device/part of hole plate print device is powered, just to optical sensor 20, specialized hardware 24 and decision means 28 supply capabilities of mother matrix table/back side sniffer 23, and form to sending the preparation that above-mentioned each device/part headed by the motor 5 etc. is powered to plate-making control part 21, heat 2, mother matrix, but become duty.Then, by with above-mentioned composing and when action plate-making, or the initiating signal of pressing generation by the plate-making starting button 41 after the replacing of mother matrix volume 10A is as triggering signal, and the starting mother matrix is sent motor 5 to, and rotation belt hold roller 3 and jockey pulley are to 4a, 4b.So 10A draws mother matrix 10 from the mother matrix volume, carry to the downstream of sub scanning direction Y.

[0053]

At this moment, shown in the solid line among Fig. 1 and Fig. 2, the scanning of the optical sensor 20 when having scanned 13 of the porous fiber films of mother matrix 10 with the single optical sensor 20 that is configured to scan, survey 13 sides of porous fiber film detects voltage waveform, as embodiment shown in Fig. 5 (a).

In 13 sides of porous fiber film, because the concentration difference that has the fiber irregular (slightly close) by Japan paper fiber etc. to produce, the mobility scale of the detection voltage of optical sensor 20 is big, for example such shown in Fig. 5 (a), it is 3.2V that max (maximum) detects voltage, it is 0.8V that min (minimum) detects voltage, and it is big to have constituted the mobility scale that detects voltage.The amplitude of its change is max-min=3.2-0.8=2.4V.

In addition, at the sweep interval of optical sensor 20, when the 3 places sampling of intermittently dotted line being represented, each detects voltage and is $2.5V\⇔1.8V\⇔2.0V,$ Because of the different variations in voltage that produce in sample position are Δ 0.7V, Δ 0.2V.

[0054]

On the other hand, when 11 of the films of scanning mother matrix 10, the scanning of optical sensor 20 detect voltage waveform as embodiment shown in Fig. 5 (c).

In 11 sides of film, because flatness is good, the change of the detection voltage of optical sensor 20 is little, shown in illustration 5 (c), it is 2.3V that max (maximum) detects voltage, and it is 1.7V that min (minimum) detects voltage, and its amplitude of fluctuation is max-min=2.3V-1.7V=0.6V, the amplitude 2.4V of the detection variation in voltage during with 13 scannings of porous fiber film compares, and the amplitude of deviation is little.

In addition, at the sweep interval of optical sensor 20, when taking a sample at 3 places that intermittently dotted line represented, detection voltage separately is $1.8V\⇔1.9V\⇔2.1V,$ Because of the different variations in voltage that produce in sample position are Δ 0.1V, Δ 0.2V.

[0055]

As mentioned above, when scanning 13 sides of porous fiber film of mother matrix 10, because the concentration difference that is produced by fiber irregular (slightly close) is arranged, the detection voltage of optical sensor 20 is big by the change that mother matrix 10 detecting locations/position produces, and has obtained the big result of deviation that detecting location produces.In contrast, during 11 sides of scanning film, because flatness is good, the detection voltage of optical sensor 20 is little by the change of detecting location/position generation of mother matrix 10, has obtained the different little results of deviation that produce of detecting location.

Like this, when scanning 11 of 13 of porous fiber films, the films of mother matrix 10 continuously or intermittently with optical sensor 20, it detects the amplitude of fluctuation difference of voltage.This amplitude of fluctuation (deviation amplitude) is judged by specialized hardware 24 usefulness decision means 28, can be differentiated the surface and the back side of mother matrix 10.

[0056]

The detection voltage waveform of the optical sensor 20 shown in Fig. 5 (a), (c), the simplification that is actually the detection voltage waveform with 11 of 13 of the porous fiber films of the mother matrix 10 of the above-mentioned 3-tier architecture of optical sensor 20 (infrared ray sensor specifically) scanning and films the time is represented.In addition, there is the scope of 4～5mm enough with the scanning distance (displacement of mother matrix 10) of optical sensor 20 when the porous fiber film 13 (or film 11 faces) of mother matrix 10 is gone up scanning.

[0057]

Then, just intermittently, discretely the method for the difference of the detection voltage of obtaining above-mentioned many places (being 3 places in the present embodiment) from the detection voltage sampling of optical sensor 20 is described.Each sample position at mother matrix 10, export register 26 to from the detection voltage of the optical sensor 20 output A/D converter 25 by specialized hardware 24, after register 26 keeps, carry out comparison, the calculus of differences of this maintained detection voltage data with arithmetic unit 27.

As illustrating,, then there is the detection voltage data of the sample position at 3 places to exist if consider the sample position at 3 places with Fig. 5.At first, when 13 of scanning porous fiber films, obtain the detection voltage of each sample position, for $2.5V\⇔1.8V\⇔2.0V.$ Obtain the variation in voltage that produces because of the sample position again, be (2.5-1.8)=Δ 0.7V, (1.8-2.0)=Δ-0.2V, (2.0-2.5)=Δ-0.5V.Like this, the difference of the detection voltage between the sample position is big, and the amplitude of fluctuation (deviation amplitude) that this expression detects voltage is big.

[0058]

Consider the situation of 11 of scanning films now, obtain the detection voltage of each sample position, for $1.8V\⇔1.9V\⇔2.1V.$ Obtain the variation in voltage that produces because of the sample position again, be (1.8-1.9)=Δ-0.1V, (1.9-2.1)=Δ-0.2V, (2.1-1.8)=Δ 0.3V.Like this, the difference of the detection voltage between the sample position is little, and the change (deviation amplitude) that this expression detects voltage is little.

The difference band of above-mentioned detection voltage has (±) number, but also can be the comparison of absolute value.

[0059]

Consider to obtain and relatively to adopt the i.e. situation of maximum difference of maximum of amplitude of fluctuation (deviation amplitude) of the detection voltage of absolute value, for example, more than Δ 0.5V, be made as amplitude of fluctuation (deviation amplitude) when big, can be judged as in 13 side amplitudes of fluctuation of porous fiber film greatly, 11 side amplitudes of fluctuation of film are little.As an example, obtain maximum difference and compare with following determine type.

Determine type: amplitude of fluctuation (deviation amplitude) is big=amplitude of fluctuation 〉=threshold value in

According to above-mentioned determine type, in 13 sides of porous fiber film,, maximum sets up because differing from 0.7 〉=0.5, and the amplitude of fluctuation (deviation amplitude) that can be judged to be detection voltage is big.

On the other hand, in the pellicular front side, maximum difference is 0.3≤0.5, because above-mentioned determine type is false, the amplitude of fluctuation (deviation amplitude) that can be judged to be detection voltage is little.

Judging part 28 depends on the computing and the comparison of above-mentioned determine type, the side that amplitude of fluctuation (deviation amplitude) is big is recognized, is judged as the face of porous fiber film 13, the side that amplitude of fluctuation (deviation amplitude) is little is recognized, is judged as the face of film 11, take into account this result of determination and, can synthetically carry out table/back side of mother matrix 10 and judge with respect to the configuration of the optical sensor 20 at the surface of mother matrix 10 and the back side.

[0060]

That is, by above-mentioned result, decision means 28 is because the change of detection voltage is little, in identification, be judged as when being 11 sides of film, according to shown in the solid line of Fig. 1 and Fig. 2, optical sensor 20 is configured to survey the situation of 13 sides of porous fiber film, comprehensively be judged as the surface that has mother matrix 10 opposite with the back side promptly correct be provided with mistake is set, by plate-making control part 21 the heat head being driven stops, the rotation that makes mother matrix send motor 5 to drives and stops, and on the LCD of guidance panel 40 display part 47, " direction that mother matrix is provided with is opposite to show for example expression.The PLSCONFM mother matrix is provided with direction." meaning warning, message.Receive this message, the user takes out mother matrix volume 10A, resets, and the surface and the back side are become correctly.

With above-mentioned opposite, the change of recognizing, be judged as detection voltage when decision means 28 is big, when being 13 sides of porous fiber film, according to shown in the solid line of Fig. 1 and Fig. 2, optical sensor 20 is arranged to survey the situation of 13 sides of porous fiber film, the surface and the back side that synthetically are judged as mother matrix 10 are set correctly, and can make it carry out above-mentioned normal plate-making, give the version action.

As mentioned above, detection voltage that can whole 3 places poor also can detect the comparison of the difference of voltage for 1 maximum, minimum place.

[0061]

The situation of continuous sampling then, is described.Because relatively going up of the detection voltage data of optical sensor 20, situation about having done after the numerical dataization is comparatively suitable, so continuous sampling also can be considered the interrupted sampling of adopting number of samples many, it describes omission in detail.Strictly speaking, detecting voltage is not continuous sampling, but the many interrupted samplings of number of samples.

As long as the sampled data amount of the detection voltage of optical sensor 20 is big, just can prevent the unexpected flase drop of data, also can improve the final decision precision.But because the problem that exists data handle to need the consumption time (data processing time) and can keep the place (toe space) of data to wait, the need coupled system be selected number of samples and contents processing.

[0062]

With reference to Fig. 6, the flow process after the detection voltage data sampling of optical sensor 20 is described.Here, be benchmark with above-mentioned data sampling content, the acquisition process of the detection voltage data of certain set point number (N time) is described.

At first, establish number of processes i=0 (zero), obtain initial detection voltage data, this is obtained data keep/be kept at (step S1 is to step S3) in the register 26.Then, go into step S4, make the counting of number of processes i increase (i+1 → i) 1 time.Then, enter step S5,, be back to step S2, begin repetition from " obtaining of detection voltage data " in the counting of number of processes i N time hour than setting value.

If finished the obtaining of detection voltage data of set point number (N time), then carry out data and handle, and decision making (step S6).Here, after the data of set point number obtain, carry out data and handle, and also can be when the detection voltage data is obtained, the parallel data of carrying out are handled.

[0063]

Here, the processing of the data of step S6 specifically is to say following processing.

(1) detects the maximum (max value) that obtains in the data

(2) detect the minimum of a value (min value) that obtains in the data

(3) calculate " maximum-minimum of a value "

(4) calculating obtains the difference (many combinations such as preceding data and existing data, existing data and back data are arranged) between the data

(5) will obtain data accumulative total

(6) calculating obtains the mean value of data

(7) calculate the above data number of certain threshold value

(8) calculate the following data number of certain threshold value

[0064]

As mentioned above, in the present embodiment, we can say to have used to be recorded in the mother matrix table/back side detection method of first aspect present invention to the third aspect.

Mother matrix table/the back side sniffer 23 of present embodiment and mother matrix table/back side detection method are not limited to the surface of mother matrix 10 of the 3-tier architecture that Fig. 5 (b) illustrates and the detection at the back side, for example also can be used for thermoplastic resin film, and also or the detection at the table/back side of the common mother matrix of stacked structure after mixing porous support that the fiber knitted behind Japan paper fiber and the synthetic fibers etc. constitutes and fitting by binding agent by Japan paper fiber or synthetic fibers.In embodiment described later or the variation etc. also is like this.

Optical sensor 20 need have the performance of the porous fiber film 13 (porous support) of (porous supports) such as the Japan paper fibers of detectable common mother matrix or mother matrix 10, but distinguish, as the explanation of above-mentioned embodiment, in the existing hole plate print devices such as プ リ Port-ト, サ テ リ オ that for example (strain) Ricoh makes, if be used for the optical sensor of the reflection-type that has or not detection etc. of the mother matrix on the printing cylinder (version housing), then can survey.

[0065]

As previously discussed, according to present embodiment, first, the parts that the detection of carrying out the table/back side of mother matrix 10 is now surveyed with 2 optical sensors (reflection-type exploring block) carry out with the optical sensor 20 of single (1), can be reduced to 1 optical sensor 20, the sensor cost reduces by half, in addition, constraint on the mechanical layout also reduces by half, and can prevent the mistake that is provided with of mother matrix 10.

According to present embodiment, second, be configured to survey at optical sensor 20 under the situation of porous fiber film 13 (porous support) face side of mother matrix 10, because 13 of optical sensor 20 scanning porous fiber films, utilize it to detect the deviation of voltage and become big in scanning/detection position, decision means 28 bases are from the many degree (many degree of the difference of output signal value) of the difference of the detection voltage of optical sensor 20, in other words, carry out the table/back side of mother matrix 10 judges according to the many degree of deviation, and porous fiber film 13 is in the outside (pellicular front curls inward) of mother matrix volume 10A, when considering the mechanical layout of optical sensor configuration, has the effect of easy configuration and design.In addition,,, be not vulnerable to the influence of generations such as mother matrix dust and dust etc. adhere to, accumulation because optical sensor 20 is configured in upside with respect to mother matrix 10, that is, the effect that is difficult for taking place misoperation is also arranged.

[0066]

According to present embodiment, the 3rd, intermittently detect the occasion of voltage sampling by sensor 20 in the many places of mother matrix 10, can reduce the voltage data amount that detects, simplify the specialized hardware structure, in addition, have the effect that required time is judged at the table/back side that can shorten mother matrix 10.

In addition, according to present embodiment, the 4th, detect the occasion of voltage sampling continuously by sensor 20 in the many places of mother matrix 10, characteristic (fiber that flatness that film is 11 or porous fiber film are 13 is irregular) that can unexpected flase drop mother matrix 10, the judgement precision the when table/back side of improving mother matrix is judged.

[0067]

(variation of first embodiment)

With reference to Fig. 2, the variation of first embodiment is described.The main difference part of this variation has following 2 points: compare with first embodiment, sensor 20 is configured to scan, survey 11 sides of film shown in Fig. 2 dotted line, to replace in the first embodiment, be configured to scan, survey optical sensor as 13 sides of porous fiber film of representing with solid line among Fig. 1 and Fig. 2; Table/back side that decision means 28 bases are carried out mother matrix 10 from the few degree (degree that the difference of output signal value is few) of difference of the detection voltage of optical sensor 20 is judged.This variation is except above-mentioned difference, and all the other are identical with first embodiment.

[0068]

[0072]

Automatic platemaker 1 is provided with mother matrix class detecting device 32.Here, so-called " automatic platemaker 1 is provided with mother matrix class detecting device 32 " says that not necessarily A/D converter 25 and the decision means 31 as the control structure major part described later of mother matrix class detecting device 32 is located in the automatic platemaker 1, and be meant to comprise by holding wire or electric wire and be electrically connected, be configured in situation on the control substrate in the device body 50 of being located at automatic platemaker 1 outside etc., be subordinated to automatic platemaker 1 in fact.

[0073]

Optical sensor 30 is located at the identical position of allocation position with the optical sensor 20 of first embodiment of Figure 1 and Figure 2, can detect the color of the coloured part 10C of painted mother matrix 10B.Optical sensor 30 is electrically connected to A/D converter 25 by holding wire.Optical sensor 30 is optical sensors of reflection-type, is provided with: the light-emitting component that is made of for example LED that the painted wavelength that depends on painted mother matrix 10B is had peak value emission wavelength characteristic; Catoptrical wavelength from the coloured part 10C of painted mother matrix 10B had the photo detector that for example phototransistor of wavelength of peak sensitivity characteristic constitutes.

[0074]

Decision means 31 constitutes by possessing the microcomputer that comprises CPU, ROM, RAM, I/O interface etc.Above-mentioned CPU also has the control function except calculation function.Decision means 31 has following function, promptly, according to operation program that accesses from above-mentioned ROM and relation data, judge the kind of painted mother matrix 10B according to the detection voltage of being imported, and send the LCD display part 47 and the plate-making control part 21 of motor 5, guidance panel 40 to by mother matrix, control heat 2 as described later.

Have in the above-mentioned ROM of decision means 31 by mother matrix and send the LCD display part 47 of motor 5, guidance panel 40 and operation program and the relation data that plate-making control part 21 is controlled heat 2 to, this operation program and relation data are suitably called by the above-mentioned CPU of decision means 31.The RAM of decision means 31 has the function with the temporary transient storage of result of calculation of above-mentioned CPU.

In control structure shown in Figure 7, the same with first embodiment because the detection voltage that sends from optical sensor 30 is the analogue value, be transformed into digital value after, when the computing of taking The noise into account and being undertaken by the decision means in the post processing 31, be favourable.

[0075]

Below, the action of mother matrix class detecting device 32 is described.

One connects (ON) power switch (not shown) in order to power to each device/part of hole plate print device, the optical sensor 30 and the decision means 31 of mother matrix class detecting device 32 just are powered, and prepare to send to power supply such as motor 5, but become duty to mother matrix.At this moment, if the mother matrix 10 of painted mother matrix 10B and Figure 1 and Figure 2 similarly is set up, then press the color detection action of stating the coloured part 10C that carries out painted mother matrix 10B with optical sensor.

[0076]

Here, being painted to blue situation with the coloured part 10C of painted mother matrix 10B for example shown in Figure 8 describes.In the optical sensor 20 that constitutes by the infrared ray sensor same (sending the infrared light of wavelength 905nm) with first embodiment, in the first embodiment under the situation of the blue same concentrations (brightness) of the white of the reference colour of the mother matrix 10 of Shi Yonging and painted mother matrix 10B, because the detection voltage that output is roughly the same can not detect the difference (poor) because of painted generation.

Illustrate with embodiment: use the optical sensor 20 that constitutes by the infrared ray sensor same (sending the infrared light of wavelength 905nm) with first embodiment, survey the white mother matrix 10 that uses in the first embodiment, with should the white mother matrix be coloured to blueness after painted mother matrix 10B the time detection voltage constitute identical 3V respectively, do not produce difference.Like this, can not discern mother matrix 10 and painted mother matrix 10B with optical sensor 20.

[0077]

Therefore, in optical sensor 20 by first embodiment of infrared sensor (for example sending the infrared light of 905nm) formation, even be the concentration (brightness) of the detection voltage difference when almost can not surveying white with blueness, it is effective changing (for example, from light-emitting component outgoing IR wavelength 905nm → from the light wavelength 630nm of light-emitting component outgoing redness) on the optical sensor 30 that the wavelength different with infrared ray responded.

Specifically, at the light-emitting component of determining to constitute by red LED with red wavelength (for example wavelength 630nm), promptly having the wavelength (redness in this example) that the blueness that is colored is responded has in the light-emitting component of peak value emission wavelength characteristic, employing is by the catoptrical wavelength from the coloured part 10C of painted mother matrix 10B (is for example had the wavelength of peak sensitivity characteristic, red wavelength 630nm) photo detector that phototransistor constitutes is as optical sensor 30, thereby, the detection voltage of optical sensor 30 that is painted to blue painted mother matrix 10B from detection specific output reduction mutually during with white.Like this, by light-emitting component being adopted the red LED that redness is had peak value emission wavelength characteristic, the concentration (brightness) that dialogue is black also can respond, but, also constitute the situation that certain particular color is responded, particularly be painted to the occasion of blue mother matrix 10B, compare during with white mother matrix 10, detect voltage output and reduce in detection.

At this moment, detecting voltage changes because of being coloured to blue concentration (brightness).If blue dense, then from the detection voltage of optical sensor 30 with regard to step-down, if white is then opposite, can uprise.Like this, there is the element of wavelength sensitivity to carry out sensing with the LED light-emitting component of redness etc. to redness, can detects blueness owing to will be painted to blue painted mother matrix 10B.

Carry out illustration with embodiment: the optical sensor 30 of the light-emitting component that constitutes with the above-mentioned red LED that is provided with by second embodiment etc. is surveyed the white mother matrix 10 of usefulness in the first embodiment, and the detection voltage during the painted mother matrix 10B of the blueness of usefulness in the present embodiment, in white mother matrix 10, obtain 3V same as described above, and in the painted mother matrix 10B of blueness, obtain 1V, produced notable difference.Like this, can discern mother matrix 10 and painted mother matrix 10B with regard to available light sensor 30.

[0078]

Here, for example, suppose white mother matrix 10 is being made as non-pure product, the painted mother matrix 10B of blueness is made as identification, the judgement of carrying out mother matrix class under the situation of pure product of high image quality mother matrix etc.The high image quality mother matrix is exactly the mother matrix that the good print image quality of pierceability improves.

For example, be the occasion of 3 (V) from optical sensor 30 via the detection voltage that A/D converter 25 is input to decision means 31, decision means 31 accesses the relation data of data form of the kind of the detection voltage of the optical sensor 30 that is stored in advance among the above-mentioned ROM and mother matrix 10, contrast with it, relatively, identification, the white mother matrix 10 of judging non-pure product has been arranged in the automatic platemaker 1, make hot 2 to stop to drive by plate-making control part 21, the rotation that makes mother matrix send motor 5 to simultaneously drives and to stop, and on the LCD of guidance panel 40 display part 47 the display list example as " mother matrix class is not the pure product of high image quality mother matrix etc.The painted mother matrix 10B of pure product of high image quality mother matrix etc. please be set " warning, the message of the meaning.Receive this message, the user takes off the mother matrix volume 10A of white mother matrix 10, resets the mother matrix volume 10A of the painted mother matrix 10B of pure product.

With above-mentioned opposite, be the occasion of 1 (V) at the detection voltage of being imported, decision means 31 identification, be judged as the blue mother matrix 10B of the pure product that correctly are provided with high image quality mother matrix etc., and make it carry out above-mentioned normal plate-making, give the version action.

[0079]

Moreover, ideal situation is, on hole plate print device, be provided with in order to set the set parts of mother matrix class, relatively with the mother matrix class information of this set parts setting and the detection voltage of the optical sensor 30 that constitutes the mother matrix class information of being surveyed, when both are consistent, be considered as being provided with best mother matrix, can drive heat 2 and mother matrix and send motor 5 to and make a plate.When both are inconsistent,, then can not waste mother matrix and printing 62, can not cause the loss of time simultaneously yet if on LCD display part 47, alert message occurs.In addition, also can in 1 mother matrix volume, change colour saturation etc., carry out the surplus of mother matrix and survey.

[0080]

In above-mentioned action example, as only just identification, the situation of judging the blueness of painted mother matrix 10B is described, but for example in automatic platemaker of representing with Fig. 11 and hole plate print device, constituting under the situation that to use the multiple class mother matrix that is colored, also can will be provided with depending on that the painted wavelength of mother matrix has the light-emitting component of peak value emission wavelength characteristic and the optical sensor (color detection parts) that the catoptrical wavelength from the coloured part of mother matrix has a photo detector of wavelength of peak sensitivity characteristic is configured to detectable painted number of packages corresponding to each mother matrix, the color of each mother matrix.

[0081]

As described above, according to present embodiment, at the optical sensor 30 that possesses the mother matrix that is colored based on detection (color detection parts) with judge from the detection voltage (output signal) of optical sensor 30 in the mother matrix class detecting device 32 of decision means 31 of kind of mother matrix, because optical sensor 30 is provided with depending on that the painted wavelength of mother matrix has the light-emitting component of peak value emission wavelength characteristic and the photo detector that the catoptrical wavelength from the coloured part of mother matrix is had the wavelength of peak sensitivity characteristic, in other words, owing to use element corresponding to the wavelength of the painted color of mother matrix, the color of mother matrix becomes and can survey, can carry out the identification of mother matrix by color, thereby, the kind of mother matrix also can be surveyed, thereby can reduce different mother matrixs are established wrong situation, and the best that can carry out this mother matrix is set the raising machine performance.
