Thereby transit control unit 275 is controlled actuator 280 and is controlled at the printed article that transports in testing fixture 200.In addition, actuator 280 is to transport roller and become the general name of electrical motor etc. of the drive source of branch's pawl what transporting of testing fixture 200 arranged on the path.Transit control unit 275 is by controlling actuator 280, to be read by image fetching unit 220 a plurality of printed articles of image, transporting interval 201 from the 1st is assigned to a plurality of the 2nd and transports interval 202a～202g, until the inspection of the image of this printed article is finished, printed article is waited in the 2nd transports interval 202a～202g, with the printed article that is through with to the inspection of image, transport interval 202a～202g from the 2nd and transport the 3rd and transport interval 203.
In addition, transit control unit 275 is based on the detection signal of printed article detecting sensor 268a～268g, and the identification printed article transports the interval and transports the interval without printed article in the 2nd of wait in the 2nd of wait.And, the 2nd transport interval number for predetermined threshold value when above at printed article what wait for, transit control unit 275 will or stop generating the control signal of printed article (printing process of printing element) for reducing the control signal of the speed (print out rate of printing element) that generates printed article, send printing device 100 to via testing fixture I/F unit 161.For example, printed article wait for the 2nd to transport interval number be that the 1st threshold value is when above, the 1st control signal (pre-BUSY signal described later) that transit control unit 275 transmits for reducing the speed that generates printed article to printing device 100, in the situation that the 2nd number that transports the interval of waiting for is more than the 2nd threshold value greater than the 1st threshold value, transit control unit 275 transmits to printing device 100 the 2nd control signal (BUSY signal described later) that is used for stopping generating printed article at printed article.
The required time of image of image inspection unit 274 inspection printed articles is depended on the data volume of image and suspects the number at the position that is defective, and is different to each printed article.Therefore, the 2nd transport interval wait time what transport the path, also different to each printed article, the printed article of spended time transports interval wait time the 2nd and spins out in the inspection of image.Here, transporting continuously in the situation that the printed article of spended time in the inspection of image, interval 202a～202g, any transports the interval (time) to the 3rd transport zone 203 with respect to printed article is transported from the 2nd, printed article is transported interval 201 from the 1st move into the 2nd to transport interval 202a～202g the interval (time) of any long, printed article increases at the number of the 2nd transport zone of waiting for.Therefore, the number of the 2nd transport zone that preferably arranges on the path transporting of testing fixture 200, the frequency that occur such as the printed article that surpasses aviation value according to average testing time of the image by simulation or the anticipation such as experiment and testing time etc. determine the 2nd to transport interval number for existing without what be printed on that thing waits for when averaging several continuous printings.
But, even in the situation that determined that as described above the 2nd transports interval number, if surpassing the printed article of aviation value, occurs continually the testing time, become printed article in all the 2nd transports the interval at the state of waiting for, follow-up printed article can't be transported to the 2nd situation of transporting the interval thereby may produce.In order to prevent this situation, the 2nd transport interval number for predetermined threshold value when above at printed article what wait for, transit control unit 275 is for printing device 100 transfer control signals.In printing device 100, printing control unit 162 obtains from the transit control unit 275 of testing fixture 200 control signal via testing fixture I/F unit 271 outputs via printing device I/F unit 161.Printing control unit 162 descends the print out rate of printing element when the control signal that receives from transit control unit 275 output, perhaps, temporarily stops the printing process of printing element, waits for increasing without printed article and the 2nd transports interval number what wait for.
Fig. 5 is that will the be through with printed article that reads of image of explanation is assigned to a plurality of the 2nd and transports the diagram of circuit of the processing in interval 202a～202g.The transit control unit 275 of testing fixture 200 for example by with the communicating by letter of printing device 100, determine from printing device 100 and discharge in the situation of printed articles, carry out a series of processing with the flowcharting of Fig. 5.
Step S101: transit control unit 275 is judged image fetching units 220 the reading for the printed article image of distribution object that whether be through with.For example, when image fetching unit 220 was through with to the reading of image, transit control unit 275 was from reading control unit 273 and directly receive or via image inspection unit 274 accept the to be through with notice of the intention that reads of image, can implementing above-mentioned judgement thus.In addition, for example, be provided for detecting in the 1st downstream of transporting interval 201 image fetching unit 22O the sensor that printed article passes through, this sensor detect printed article by the time, be judged to be reading of the image that is through with, also can implement above-mentioned judgement thus.Transit control unit 275 in the situation that step S101 be judged to be "No", the judgement of repeating step S101, in the situation that step S101 be judged to be "Yes", enter step S102.
Step S102: whether transit control unit 275 judgements a plurality of the 2nd are transported has printed article to transport the interval in the 2nd of wait in interval 202a～202g.For example, transit control unit 275 is confirmed the detection signal of printed article detecting sensor 268a～268g, can implement this judgement thus.In addition, transit control unit 275 confirms that whether the printed article of distribution objects is the printed article of front that generates the operation of a plurality of printed articles, also can implement above-mentioned judgement thus.In this case, in the situation that the printed article of distribution object is the printed article of the front of operation, transit control unit 275 is judged to be does not have printed article to transport the interval in the 2nd of wait, in the situation that the printed article of distribution object is not the printed article of the front of operation, transit control unit 275 is judged to be printed article and transports the interval in the 2nd of wait.Transit control unit 275 in the situation that step S102 be judged to be "No", enter step S103, in the situation that step S102 be judged to be "Yes", enter step S104.
Step S103: transit control unit 275 determines that the distribution locations of the printed article of distribution object transport reference position in interval 202a～202g, that distribute and namely the 2nd transport interval 202a for a plurality of the 2nd, enters step S106.
Step S104: transit control unit 275 enters step S105 from read the distribution locations of previous printed article (at the previous printed article that transports of the printed article of distribution object) at the not shown memory devices such as SRAM of transit control unit 275 interior settings.
Step S105: transit control unit 275 determines the distribution locations of the printed article of distribution object, and enters step S106 based on the distribution locations of the previous printed article of reading at step S104.In addition, the distribution locations of printed article is transported interval 202a, the 2nd with the 2nd and is transported interval 202b, the 2nd and transport interval 202c ... sequential transfer, and transport interval 202g in the situation that transfer to the 2nd, turn back to the 2nd and transport interval 202a, the distribution locations of the printed article of distribution object becomes the next position of the distribution locations of previous printed article.For example, if the distribution locations of previous printed article is the 2nd to transport interval 202a, transit control unit 275 determines the distribution locations of the printed article of distribution object for transporting interval 202b.In addition, if the distribution locations of previous printed article is the 2nd to transport interval 202b, transit control unit 275 determines to be the 2nd to transport interval 202c with the distribution locations of the printed article of distribution object.In addition, if the distribution locations of previous printed article is the 2nd to transport interval 202g, transit control unit 275 determines to be the 2nd to transport interval 202a with the distribution locations of the printed article of distribution object.
Step S106: thus 275 pairs of actuators 280 of transit control unit control and make the position of branch's pawl 261～266 just right, guide to the distribution locations that determines with the printed article with distribution object in step S103 or step S105, and enter step S107.
Step S107: the distribution locations that transit control unit 275 will determine in step S103 or step S105 is associated with printed article ID, and is kept at and is arranged in the memory devices such as SRAM in transit control unit 275, not shown, then enters step S108.
Step S108: transit control unit 275 judges with respect to be assigned to the 2nd in step S106 to transport in interval 202a～202g, whether the 2nd printed article that transports the interval of any has follow-up printed article.For example, transit control unit 275 is confirmed to be at image fetching unit 220 and is through with to the new printed article after the reading of image, and can implement above-mentioned judgement thus.In addition, all discharge signals to testing fixture 200 output printed articles in the situation that printing device 100 is each when discharging printed article, transit control unit 275 this printed articles of catcher are discharged signal, also can implement above-mentioned judgement thus.Transit control unit 275 in the situation that step S108 be judged to be "Yes", turn back to step S104, repeat later processing, in the situation that step S108 be judged to be "No", finish in a series of processing shown in the diagram of circuit of Fig. 5.
In addition, in the above description, transit control unit 275 is kept at the distribution locations of previous printed article in memory device, based on the distribution locations of preserving in this memory device, determine the distribution locations of the printed article of distribution object, but also can replace, by confirming at any time the detection signal of printed article detecting sensor 268a～268g, determine thus the distribution locations of the printed article of distribution object.
