Medium is under the situation of the light conductor 80 shown in Figure 53 and Figure 54, and the operator is used at light conductor 80 printing one or more lines in order to cover up the data of bright line near its light-incident end that disposes main light source 174 to the input of the control circuit portion of this device by guidance panel 42.Only tackle under the situation of the last bright line that light conductor 80 occurs, shown in Figure 53 (A) and Figure 53 (B), on light conductor 80, draw to be useful on and cover up on this once bright line lines L1, but need under the situation of last bright line of reply and following secondary bright line, except the lines L1 that is used for last bright line, also be used to print lines L2 in order to cover up down the data of secondary bright line from the guidance panel input.By this data input, utilize this plotting unit shown in Figure 54 (A) and Figure 54 (B), two line L1, L2 that cover up last bright line and following secondary bright line are with on 1 (Y-axis) direction, keep predetermined distance, mode parallel to each other to be plotted on the light conductor 80 on 2 (X-axis) directions.

Also have, printing on the medium 80 under the situation of many lines, the combination of ink can with black ink with identical ink such as black, but according to circumstances need different inks sometimes, therefore printhead 10a can be with each lines of different printhead prints, so that can tackle lines such as black and grey with different inks respectively.

Above-mentioned embodiment is that the button of guidance panel 42 is operated, the content that input is selected, determined, but use liquid crystal display formula touch panel etc., the also input that can understand easily by picture.The operator then or before the data input operates micrometer 58,60,62 in advance, and positioning body 76 is adjusted into correct position.

Then, the medium 80 of formation such as light conductor is positioned on the mounting table 52, foot-switch 74 with after the restriction face of the both direction of positioning body 76 contacts, is stepped in the edge of medium 80, drive adsorbent equipment 72, mounting table 52 is fixed in medium 80 absorption.Then, printing beginning switch 84,86 is connected, balladeur train 6 begins moving from one of them printhead position of readiness to another printhead position of readiness by the control to control circuit portion 40.This printing beginning switch 84,86 needs two to be pressed simultaneously, owing to be in the position that one hand can't get at, the operator can the error starting device, is unlikely to cause media damage, waste etc.In addition, the structure of this device, in order to carry out the replacement operation of medium rapidly, cover cap is not established in the zone of typewriting head work, therefore can prevent that by both hands while push switch hand from entering.In addition, printing beginning switch 84,86 also can be pushed not exclusively simultaneously, and some (pausing the several seconds) mistimings also can be arranged.

On the other hand, after UV-lamp 22 illuminating states of ultraviolet lamp 16 were stable, driving motor 26, shutter 28 deviated from respect to peristome, and peristome 24 is opened.Printhead 10a scans medium 80 by moving of balladeur train 6, from nozzle ejection ultraviolet hardening ink, according to print data print parallel line L1, L2 or lines L1 on medium 80 of guidance panel 42 settings.Printing portion irradiation ultraviolet radiation from 24 pairs of media 80 of peristome of ultraviolet lamp 16 carries out the ink cure process to printing portion.When head 10 arrives on another position of readiness, finish printing action to medium 80.And when turning back to the position of readiness on right side, just finish cure process fully by only shining.

In above-mentioned printing action, as shown in figure 13, head 10 begins when right side printhead position of readiness moves to the figure left, and ultraviolet lamp 16 enters medium mounting scope (print area) before, begins to utilize shutter 28 to open the action of peristome 24.In addition, as shown in figure 14, head 10 moves to right-hand from the printhead position of readiness in left side, turn back in the head moving process of right side printhead position of readiness through print area, the peristome 24 of beginning ultraviolet lamp 16 promptly shines the closing motion of mouth on predefined shutter close starting position, and removes the absorption that adsorbent equipment 72 is carried out on the absorption position of the finish time.

Like this, head turns back in the moving process of printhead position of readiness through irradiation area, the closing motion of the shutter of beginning ultraviolet radiation port carries out open and close controlling in the moment of its end to shutter, in addition, head turns back in the printhead moving process of printhead position of readiness through print area, enter the control of removing adsorbent equipment 72, can shorten next time medium thus and replace the needed time.

Also have, as shown in figure 29, the both sides that ultraviolet lamp 16 are disposed at head 10 are its left-hand seat side and these both sides of assistant's side, no matter which limit printhead position of readiness can both standby in the left and right sides for head 10, can carry out the ultraviolet ray irradiation to the ink of firm printing.Specifically, on the outlet of head 10, the irradiation that the printing portion to firm printing carries out is born at the direct of travel rear wherein ultraviolet lamp 16 of a side, on the loop, bear the irradiation that the printing portion to firm printing carries out by the ultraviolet lamp 16 of the opposite side at the direct of travel rear of head 10.By carrying out like this, on outlet and loop, respectively carry out the replacement of a medium 80, can increase work efficiency back and forth printing twice in the process.

The length-wise axis of irradiation mouth (peristome 24) that is arranged in the ultraviolet lamp 16 of head 10 both sides as shown in figure 29 or is disposed at the one-sided ultraviolet lamp 16 of head 10 as shown in figure 28 is with respect to the structure of printhead direction of transfer configured in parallel, when printing lines, even improve the carriage speeds of printhead 10a, the axis of the irradiation mouth of ultraviolet lamp 16 is moved on same axle with respect to the drafting portion of lines, therefore have sufficient ultraviolet ray to shine lines drafting portion based on printhead 10a.In addition, ultraviolet lamp 16 can be in vertically (promptly rectangular for the direction that relatively moves of supporting station 36 with respect to head 10 as the ultraviolet lamp 16 in Figure 30 left side), laterally (promptly parallel for the direction that relatively moves of supporting station 36 with respect to head 10 as the ultraviolet lamp 16 on Figure 30 right side) upward rotation or assembling, therefore when drawing lines, carry out laterally, during the printing (using the printing of printhead) of printhead width, separately use according to purposes can resembling vertically along whole nozzles of the nozzle rows of X-axis.

In addition, be with a side wherein serve as vertically, the opposing party is horizontal this structure, also can separately use according to the purposes of head 10 Print directions.Specifically, for example in the moving of the outlet of head 10 (being moved to the left among the figure), carry out the printing of lines in Figure 30, utilizing wherein, 16 pairs of printing portions of ultraviolet lamp of a side traverse shine.In addition, in the moving of the loop of head 10, print the printing of head width, in this case, manage to utilize 16 pairs of printing portions of the vertical ultraviolet lamp of putting of opposite side to shine.
