Printing equipment
Technical field
The present invention relates to printing equipment, more particularly, relate to the printing equipment that comprises hole plate print device etc. with function of keeping secret.
Background technology
In the past, as easy mode of printing, the digital hole plate print device of temperature-sensitive is known.In this printing equipment, the thermal head that small heater element becomes row or multiple row to arrange to form with as an example of the version of printing usefulness, temperature-sensitive perforation master (below be called " master ") contact with thermoplastic resin membrane, by the limit this heater element is carried out the pulsed energization limit and carry master with master conveying mechanisms such as lettering platen rollers, thermoplastic resin membrane's part of the feasible master that contacts with the heater element of thermal head is bored a hole according to the image information fusion, thereby on master, form the perforation image, afterwards, the master (below be called " plate-making original edition ") of will boring a hole is wrapped on the outer peripheral face of the printing drums that also is known as plate cylinder, with pressing mechanisms such as pressure rollers printing sheets (below be called " paper ") is overlayed on the outer peripheral face of plate cylinder, China ink is oozed out from the perforate position of plate cylinder and the site of perforation of master, and this China ink is transferred on the paper and is obtained the printing image.Below, in this specification and claims, plate cylinder being called " printing drums ", all thin portion structures to printing drums all will relate to plate cylinder when describing.
In this hole plate print device, when behind printing end, replacing original copy, carrying out subsequent printings, at first, to press the operation of plate-making beginning key by the user, the master that will remove after version mechanism will use from the plate cylinder outer peripheral face of printing drums is peeled off, and the general is for example installed on the plate cylinder outer peripheral face of printing drums automatically by the master reel after the newly formed plate-making of the first-class plate-making mechanism that constitutes of temperature-sensitive.Why like this reason of design is, if the master after will using from the printing drums immediately after printing finishes is peeled off down, then prior to this section before the master after the new plate-making of subsequent printings package in the period, printing drums is in the state of peripheral exposure in atmosphere, and place this state for a long time, to cause remaining in the outer peripheral face of printing drums and the China ink curing at perforate position, can hinder flowing and causing and to print well of China ink when carrying out the printing of next edition, therefore, master reel after the use is on the outer peripheral face of printing drums, to prevent printing drums outer peripheral face drying, guarantee the flowability of China ink.
But, if the master reel as mentioned above after the use is on printing drums, then changes and do not press plate-making beginning key and press printing beginning key or examination when printing key as the user of hole plate print device, previous user's original copy former state will be printed.This is a very big problem when the original copy content as original copy information belongs to the content of not wishing to be known by other user or duplicating, promptly should maintain secrecy.In order to address this problem, a kind of can be known to the technology that original copy is maintained secrecy, promptly, setting relates to the security schema of a series of actions that prevents that original copy from divulging a secret, and when being set at this pattern, can be with discarded, and the new not master reel of plate-making that will be known as the master of not making a plate installs on the plate cylinder as the master version of making by the original copy that relates to secret, after the plate-making, thus realize the maintaining secrecy of original copy (for example can with reference to patent documentation 1).
And a kind of solution spy opens the technology of the following problems that the disclosed technology of clear 59-198185 communique (patent documentation 1) exists also known (for example can with reference to patent documentation 2 to 4), promptly, owing to the master reel of not making a plate will be contained on the printing drums when being in security schema, thereby will be attached on the master of not plate-making and to be removed version with this master discarded as the China ink of running stores, cause the unnecessary waste of this master and China ink, cause cost to increase.
And the spy opens the disclosed technology of clear 63-74679 communique (patent documentation 2), be in Printing Department, be placed with press under the state of original copy the beginning key then after removing the version action, make a plate automatically action, print and move, if pressing the beginning key under not placing the state of original copy then only prints in a kind of like this hole plate print device of action, if input signal input store from privacy key, then when being in the state of not placing original copy, do not print action, thus can not cause master realize maintaining secrecy of original copy lavishly.Can provide a kind of like this porous printer and specially permit the disclosed technology of No. 2716964 communique (patent documentation 3), promptly, if operate privacy key security schema is stored in the control part, then not placing other original copy does not just print, even and stored security schema is not still lost when dump, therefore, not only can not waste master ground and realize maintaining secrecy of original copy, and do not need to use replacing between the new master of original edition and not plate-making, thereby can avoid operating the prolongation that causes stand-by time because of the operator.
The disclosed technology of Te Kaiping 8-183238 communique (patent documentation 4) has then solved such problem, promptly, even wanting to adopt above-mentioned spy to open clear 59-198185 communique and above-mentioned spy opens clear 63-74679 communique and distinguishes disclosed technology, so that under the security schema state, thereby the printing action is limited maintaining secrecy of realization original copy, but, in nearest many hole plate print devices, be provided with and a kind ofly have in order before printing, paper to be carried out that the position of original image and the concentration of original image etc. are confirmed and the examination printing key of the examination printing functionality that prints on a small quantity, if this examination printing key is pressed, then can't realize maintaining secrecy and former state being printed of original copy, perhaps, can be from the device body printing drums (plate cylinder) be taken off again the master of package is peeled and its content is carried out interpretation from printing drums.
Promptly, open the disclosed technology of flat 8-183238 communique according to above-mentioned spy, when privacy key is pressed, controlling organization only makes the input of plate-making beginning key effective, and, only when plate-making beginning key is pressed, security schema is removed, and as storing mechanism, in case privacy key is pressed, press and before security schema is disengaged up to plate-making beginning key, will be always " remembering " be set at security schema, therefore, when being in security schema, do not print action or examination printing action even press printing beginning key or examination printing key yet, can realize maintaining secrecy of printed article, in addition, the mode of removing this security schema can only be to press plate-making beginning key, unless thereby the secret content master that is made into version is removed a version mechanism and is peeled off from plate cylinder, discarded, security schema just can not removed, and therefore, can also prevent to divulge a secret by the master of making version.In addition, the storing mechanism that stores security schema will store security schema always before security schema is disengaged, and therefore, when being in security schema, even the dump of hole plate print device, security schema can not removed yet, and has the high effect of confidentiality.In addition, when privacy key is pressed, controlling organization forbids that plate cylinder breaks away from from device body, therefore, also has such effect, promptly, can prevent to pull down plate cylinder, on other identical hole plate print device, print and cause divulging a secret, perhaps from hole plate print device, peel off master after the plate-making from plate cylinder, master itself is understood and the situation that causes divulging a secret takes place.

Below, the operation principle (operation) of hole plate print device 1 is described.
At first, the action when the common action of the hole plate print device of implementing when not pressing privacy key 138 1, not need to be keep secret describes.Here, suppose that drawing unit 25 is shown in the solid line of Fig. 1, be positioned at the plate-making latched position of installation in position in body frame 2, drum unit 50 is shown in the solid line of Fig. 1, be positioned at the bulging latched position of installation in position in body frame 2, remove version unit 82 shown in the solid line of Fig. 1, be positioned at the remove edition latched position of installation in position in body frame 2.In addition, supposing that front door 111 is positioned at is closed on the door locked position that is locked on the framework front baffle 120 shown in Figure 8.
When after the user is on the original copy mounting table 10 that original copy 11 is placed on manuscript reading section 3, by the various key assignments plate-making conditions on the operation panel 125, pressing plate-making beginning key 126, just produce commencing signal, at first remove the version action as triggering signal.In this state, on the plate cylinder outer peripheral face of printing drums 51 still package employed when carrying out printing last time, in this example for not having the master 26d after the use of confidential information.
The command signal of sending according to control device 140 (following be called sometimes " instruction "), CD-ROM drive motor 65 startings (beginning rotation), thereby printing drums 51 rotates to clockwise direction in Fig. 1.Afterwards, judge printing drums 51 when control device 140 and arrive the front end that uses original edition 26d corresponding to last remove version roller 80 set when removing the version position, when the rotation of printing drums 51 stops, instruction according to control device 140, not shown swing mechanism and the above-mentioned version motor that removes move, upward remove 80 rotations of version roller and upward peel off the position shown in double dot dash line, the front end of the master 26d after using is raised except that a version roller 80 moves to.When last master 26d after removing version roller 80 and using contact, printing drums 51 was once more to the clockwise direction rotation, was clamped in by the last master 26d that removes after the use that version roller 80 raises and removed version roller 80 and following between edition roller 81, peeled off from the outer peripheral face of printing drums 51.With remove more than the master 26d after the use after peeling off version roller 80 with remove down 81 clampings of version roller to the Y1 direction carry and output to remove in the version box 83 after, with compressive plate 84 it is compressed.During this compression, when being the master 26e after the recovery more than in removing version box 83, having held to a certain degree, the compression of the given time that the master 26e after 84 pairs of recovery of compressive plate carries out (for example 2 seconds).
After even the master 26d after using peels off from outer peripheral face fully, printing drums 51 is also continuing rotation.When printing drums 51 arrival detected as the original position of adjustment of the printing plate shown in Figure 1 position and by home position sensing 69, this home position sensing 69 was to control device 140 output signals.Control device 140 sends instruction to CD-ROM drive motor 65 and makes it stop action according to the signal from home position sensing 69.When printing drums 51 stopped in position, control device 140 sent instruction to not shown switching mechanism, and clamper 52 is opened from boss 53 shown in double dot dash line, and printing drums 51 is in adjustment of the printing plate holding state shown in Figure 1, removed the version release.
Except that carrying out original image simultaneously, version action ground reads action with above-mentioned.Promptly, carry the starting of motor along with not shown original copy, separate roller 14 rotations, with the original copy on the original copy mounting table 10 11 forward the original copy conveying roller to sending between 13a, the 13b, afterwards, the preceding original copy conveying roller of the front end by clamping original copy 11 is to the rotation of 13a, 13b, with original copy 11 further backward the original copy conveying roller to sending between 16a, the 16b, then by of the rotation of back original copy conveying roller, original copy 11 is outputed on the original copy output table 15 16a, 16b.At this moment, for the front of the original copy 11 that moves on contact glass 17, shine with fluorescent lamp 18, the reverberation that the front of original copy 11 is reflected incides in the imageing sensor 21 through lens 20 after speculum 19 reflections, and the image of original copy 11 is read.At this moment, if stacked many original copys 11 on the original copy mounting table 10, then send successively to carry out reading of image by 12 1 Zhang Jinhang separation of separating plate and from nethermost original copy 11 beginnings.
Become data image signal in the A/D converter in the picture signal input body frame 2 after imageing sensor 21 carries out opto-electronic conversion, and then carry out image at above-mentioned picture signal handling part and handle, the data image signal after handling through image is sent among the CPU141.
On the other hand, when the image that carries out above-mentioned original copy 11 reads, in plate-making write section 4, according to handle through above-mentioned picture signal handling part and not shown plate-making control part, through the data image signal that control device 140 is sent, make a plate and for version action.That is, according to the instruction of CPU141, the starting of above-mentioned stepper motor is gone up from master reel 26a master 26 is pulled out, and presses against the rotation of the lettering platen roller 29 on the thermal head 28 by sandwich master 26, carries to the downstream of master throughput direction Y.For the master of as above carrying 26, according to data image signal a plurality of small heater element of arranging that is in line on the thermal head 28 is generated heat respectively, thus thermoplastic resin membrane's partial melting perforation of the master 26 that heater element feasible and heating contacts.Like this, by with the position of the corresponding master 26 of image information on fusion perforation selectively, image information can be become perforation pattern.To the master 26c after the plate-making of the plate-making of as above boring a hole, by the rotation of 31a, 31b being carried for the version roller, and to 33 direct of travel changing downwards with guided plate, the clamper of opening 52 places towards the printing drums 51 that is in adjustment of the printing plate holding state shown in Figure 1 send with its front end.
Next, when CPU141 judges along with the set step number of above-mentioned stepper motor rotation, when the front end arrival boss 53 of the master 26c after the plate-making and the both allocations between the clamper 52, clamper 52 is just with corresponding set sequential closure, so, the front end of the master 26c after the plate-making is clamped, then, along with printing drums 51 rotates to the clockwise direction shown in this figure arrow, the master 26c after the plate-making is wound up on the outer peripheral face of printing drums 51.When CPU141 judges along with the set step number of above-mentioned stepper motor rotation, when the plate-making of a space of a whole page is finished, this stepper motor is stopped, thereby make lettering platen roller 29 and supply the version roller that the rotation of 31a, 31b is stopped, and, move to the width rotation limit perpendicular to the master of master throughput direction Y on the movable sword limit of the top of cutter 30 among Fig. 1, and master 26 is cut to set length.After the master 26c after will this cut plate-making that comes pulls out and is wrapped on the outer peripheral face of printing drums 51 from plate-making write section 4 fully, when printing drums 51 arrives original position once more, according to the instruction that CPU141 sends, CD-ROM drive motor 65 stops action, plate-making and adjustment of the printing plate release.
Secondly, begin also to be known as the what is called of trying printing and lock up the printing action.Instruction according to CPU141, CD-ROM drive motor 65 startings, printing drums 51 is rotated to the direction of arrow in Fig. 1 with low speed, and above-mentioned paper supply motor starting, the paper supply roller 100 and the separation roller 101a that drive sheet feed section 7 rotate to clockwise direction, simultaneously, by the rotation of the preceding absorption exit roller 106,107 in row's paper portion 8, drive belt conveyor 108 and absorption and rotate with fan 109.The two turns clockwise with separating roller 101a along with paper supply roller 100, with the uppermost paper S that overlays on the feedboard for paper 99, isolate one by minute synergy of paper roll 101a, 101b, 102a, 102b are sent to arrow Y4 direction towards the damping roller.
Next, a piece of paper of separating open S temporary transient conflict the damping roller to the two pincers oral area of 102a, 102b on and after being maintained and forming set deflection, by the damping roller to 102a, 102b, with with the sequential of the rotation synchronised of printing drums 51, paper S is sent between printing drums 51 and the pressure roller 58.When the paper S that 102a, 102b is sent when the damping roller is detected by not shown note detection mechanism, CPU141 is just according to its signal, make pressure roller 58 remain on locational, the card locking mechanism that leave from the plate cylinder outer peripheral face of printing drums 51 and remove hold mode with not shown solenoid and extension spring etc., thereby make the pressure roller 58 that leaves from the outer peripheral face of printing drums 51 be moved upward, paper S is overlayed on the master 26c after the plate-making on the outer peripheral face of the printing drums 51 that is wrapped in the direction of arrow rotation in this figure.
So China ink partly oozes out from the porous part of the plate cylinder of printing drums 51 and the perforation pattern of the master 26c after the plate-making, this China ink is transferred on the surface of paper S and is printed out the printing image.At this moment, in the interior week of above-mentioned plate cylinder, supply with China ink from a plurality of ink supply aperture 54a of ink supply pipe (fulcrum) 54 to being formed at long-pending black 57 between ink roller 55 and the dancer rools 56, the ink roller 55 that contacts with inner peripheral surface by to the direction identical with the direction of rotation of printing drums 51 and with the rotation synchronously of the rotary speed of printing drums 51 time is with China ink week supply in the plate cylinder of printing drums 51.
For the paper S that in Printing Department 5, has formed the printing image, when with separation claw 105 it being peeled off from printing drums 51, adsorbing with fan 109 with absorption, Xuan Zhuan belt conveyor 108 is carried to arrow Y5 direction in the counterclockwise direction, on its row's of outputing to paper platform 110.By above-mentioned series of processes, lock up the printing release, hole plate print device 1 enters the printing holding state.
In the above-mentioned version of removing, original copy reads, plate-making, lock up wait each release and enter the printing holding state hole plate print device 1 in, when the user presses examination printing key 128, will be with to lock up when action same, uppermost paper S on the feedboard for paper 99 is passed through paper supply roller 100 and separates roller 101a, 101b isolates one and sends, temporarily conflict to 102a at it at the damping roller, on the two the pincers oral area of 102b and after being kept, along with instruction CD-ROM drive motor 65 startings according to CPU141, printing drums 51 will high suitable speed rotate with the low speed of ratio during above-mentioned locing up of setting by print speed printing speed setting key 134.The damping roller to 102a, 102b with and the corresponding set sequential of print speed printing speed paper S is sent between the printing drums 51 of rotation at a high speed and pressure roller 58.The paper S that sends is overlayed by pressure roller 58 and on the master 26c after the plate-making on printing drums 51 China ink is shifted and form in the above after the printing image, with separation claw 105 its outer peripheral face from printing drums 51 is peeled off, carry to left by belt conveyor 108, on the output row of the stacking paper platform 110.Printing drums 51 is got back to original position once more, examination printing release.
By this examination printing the concentration or the position of printing image are being confirmed, with the various keys on the operation panel 125 this is adjusted and tries once more the printing after, to print number by numerical key 130 and put number on display unit 135, set print speed printing speed with print speed printing speed setting key 134, when suitably pressing key such as multiplying power key 136c according to needed printed article and pressing printing beginning key 127, will be to lock up with above-mentioned, the operation that the examination printing is same, the printing number of setting according to put number carries out paper supply repeatedly, each operation such as printing and row's paper, all process steps constipation bundle of porous printing.After the printing release, printing drums 51 is got back to original position once more.
Below, the action that relates to security schema of hole plate print device 1 describes during to use privacy key 138.At first, to being set at security schema but do not append the example of printing, the example that promptly is wrapped in the master 26d after the use that master on the printing drums 51 belongs to need to be keep secret describes.
The user can through with above-mentioned same plate-making, take the circumstances into consideration to carry out lock up and try each operation such as printing, printing and obtain printed article.Occasion in the content need to be keep secret of this printed article, as if secret leaks into user's (being designated hereinafter simply as " user ") that will make troubles in third party's hand, need maintain secrecy, certainly will the printed article of need to be keep secret not by known to the third party, under the state seen with above-mentionedly similarly implement above-mentioned plate-making, lock up, try each operation such as printing, printing.After the printing release that need are maintained secrecy, owing to existing confidential information certainly on the master 26d after the use that is wrapped on the printing drums 51, therefore, the user will press privacy key 138 after the printing release that need are maintained secrecy.
When privacy key 138 was pressed, operation panel 125 will be carried the relevant signal of setting security schema to CPU141.CPU141 accesses the security schema program from ROM143, when writing the security schema program to RAM142, sends command signals to operation panel 125, is loaded on above-mentioned LED in the privacy key 138 in making and lights with expression and be in security schema.After writing the security schema program to RAM142, the CD-ROM drive motor 65 of CPU141 in main drive division 72 sends the action command signal, make the printing drums 51 that stops at original position rotate set angle (distance L among Fig. 4), till shadow shield 68 is detected by security schema position sensor 70, enter the state of the drum gear shown in Fig. 5 (b) for example 60 and driven wheel 61 the two engagement.
Like this, directly over the rotatable phase position that is in driven wheel 61 shown in Fig. 5 (b) is positioned at roughly for notch part 61c during the state of position, be subjected to stopping of flange part 61b with the drum gear 60 of the gear part 61a of flange part 61b engagement, thereby forbid in Fig. 5 (b) with respect to drawing to reader's one side, be that drum unit extraction direction X shown in Figure 4 extracts and even make it drum unit 50 out disengaging together with drum gear 60, therefore, after can preventing from from body frame 2, will have drum unit 50 extractions of printing drums 51 and even making it disengaging, in other similar hole plate print device, print and obtain secret, or, master 26d after using is stripped down from printing drums 51, master itself is understood and obtained secret, or see the confidential information on the plate-making picture (, being erect image sometimes) of the master 26d after the use that still is wrapped on the printing drums 51 or it is transferred to the generation of obtaining situations such as confidential information on the paper in two-face printing device though be generally mirror image.
Simultaneously, after writing the security schema program to RAM142, CPU141 makes the command signal of these solenoids actions by each solenoid drive circuit not to the solenoid 42 of plate-making drive division 47, except that solenoid 92 outputs of version drive division 97, control each solenoid 42,92 and remain on each latched position, thereby each solenoid 42,92 is failure to actuate and keeps off-position.So, drawing unit 25 is will be shown in the solid line among Fig. 1 and Fig. 3 (a) locked to be fixed on the plate-making latched position, thereby can't be from body frame 2 drawing unit 25 is extracted out and even make it and break away from.And as removing version unit 82, shown in the solid line of Fig. 7, will lock the state that removes on the version latched position that be fixed on owing to remain on its securing rod 90 that removes version locking mechanism 89, thereby can't from body frame 2, will extract and even make it disengaging out except that version unit 82 except that version unit 82.Therefore, can prevent to see the confidential information on the plate-making picture (, being erect image sometimes) of the master 26d after the use that is wrapped on the printing drums 51 or it is transferred on the paper and carries out the collection of confidential information in two-face printing device though be generally mirror image.
At the same time, after writing the security schema program to RAM142, the command signal that CPU141 does not move by solenoid drive circuit to solenoid 117 outputs of door locked mechanism 114, solenoid 117 controlled and it is remained on open and close on the latched position, thereby solenoid 117 is failure to actuate and keeps off-position.So, because front door 111 remains on the locked locational state of door locked that is fixed on shown in Figure 10 (a), thereby front door 111 can't be opened from framework front baffle 120.Therefore, can prevent to see the confidential information of the plate-making picture of the master 26d after the use that is wrapped on the printing drums 51 conscientiously, perhaps from and the gap that constitutes between the plate cylinder outer peripheral face of printing drums 51 of drum unit 50 see the confidential information of transfer printing plate-making picture on the paper and carry out the collection of confidential information.
Afterwards, when the user presses printing beginning key 127 or examination printing key 128, operation panel 125 will be carried signal to CPU141, but because CPU141 recognizes the security schema program that writes among the RAM142, above-mentioned each the controlled driving mechanism in main drive division 72 is not exported the command signal of moving, therefore, under the control of CPU141, hole plate print device 1 does not print action and examination printing action.In addition, CPU141 is pressed and when signal is arranged from operation panel 125 inputs, will sends signals to operation panel 125 at printing beginning key 127 or examination printing key 128, makes the message that shows " can not print " on display unit 136.This security schema state will last till always by above-mentioned security schema cancel system security schema is removed till.In addition, unquestionable, because RAM142 is buffer storage as mentioned above, therefore,, still can keep above-mentioned confidential state even be used for having no progeny to the power switch pass of hole plate print device 1 supply power.
Below, being set at security schema and appending the example of printing using privacy key 138, the example that promptly is wrapped in the master 26c after the plate-making that master on the printing drums 51 belongs to need to be keep secret describes.After the printing release of the set printing number that need are maintained secrecy, need to append printing sometimes.When running into this situation, if the user is in order to remove the security schema set condition, will be used in combination with definite key 131 as the numerical key 130 of security schema cancel system, for example with after determining that key 131 is pressed " 6; 7; 8,9 " as password in order, press and determine that key 131 determines to set to " 6; 7; 8,9 ", just there be the signal relevant to send to CPU141 from operation panel 125 with the security schema releasing.So, CPU141 is when the security schema program among the RAM142 of will writing on is wiped, being contained in above-mentioned LED in the privacy key 138 in making extinguishes with expression and is in the security schema disarm state, and, by sending the action command signal to main drive division 72, above-mentioned each controlled driving mechanism to the Printing Department 5 of hole plate print device 1, sheet feed section 7, row's paper portion 8 is controlled, thereby enters the state that can append the printing action.
As user and above-mentioned same, on display unit 135, print putting number, setting print speed printing speeds, as required printed article with print speed printing speed setting key 134 and suitably press when pressing printing beginning key 127 behind the key such as multiplying power key 136c of number with numerical key 130, will with carry out the above-mentioned same operation of printing of locing up, try, the printing number of setting according to put number that appends carries out each operation such as paper supply, printing and row's paper, all process steps constipation bundle of porous printing repeatedly.After the printing release, printing drums 51 will be got back to original position once more.Need maintain secrecy append the printing release after, be wrapped on the master 26d after the use on the printing drums 51 and exist confidential information certainly, therefore, the user will need maintain secrecy append the printing release after press privacy key 138 once more.
In the present embodiment, drawing unit locking mechanism 38 double as are for the replacing of carrying out master reel 26a and paperboard processing of master etc. and the locking mechanism when installing and removing, drum locking mechanism 59 double as are handled for the paperboard of carrying out paper and master, the supply of China ink or colour changing etc. and locking mechanism when installing and removing, remove version locking mechanism 89 double as after for discarded the recovery master and use the paperboard processing etc. of original edition and locking mechanism when installing and removing, therefore, the locking mechanism that past had can directly be used, thereby not only can make simple in structurely, therefore and can avoid the increase of cost.
In the present embodiment, except reason owing to the locking mechanism of double as such use separately, also be the security consideration (for example isolating) during from 25,50,82 actions of each unit, be provided with above-mentioned each locking mechanism 38,59,89,114 with the drive part headed by the printing drums 51 of rotation.Therefore, preferably, at each unit of each unit 25,50,80, be provided as on operation panel 125 that each that allow its disengaging set mechanism that breaks away from from body frame 2 breaks away from key and the key that opens the door of the set mechanism that opens the door opened from framework front baffle 120 as permission front door 111.
So, just can carry out such design, promptly, break away from before key and the above-mentioned key that opens the door press up to above-mentioned each, CPU141 with not to plate-making drive division 47 solenoid 42, remove the solenoid 92 of version drive division 97, the solenoid 117 of door locked mechanism 114 sends the electrical instruction signal ground respectively and controls, therefore, can avoid special Fig. 6 that opens flat 8-183238 communique of picture and shown in Figure 7, it is such that paragraph 0057 to 0059 is put down in writing, will be once more after the security schema program is wiped free of the energising of solenoid 93 that the lock-out state of plate cylinder 7 is removed be caused the unnecessary consumption of electric energy, help energy savings.Promptly, as CPU141, up to have break away from the signal input of lock-out state key and the above-mentioned key that opens the door, that be intended to remove each locking mechanism from above-mentioned each before, the control and of can always cutting off the power supply to each solenoid 42, solenoid 92, solenoid 117 energisings.
In addition, no matter which kind of type the type of hole plate print device is, in order to accomplish maintaining complete secrecy of confidential information, can constitute like this, promptly, when being in the security schema set condition, even have from breaking away from key as the drawing unit that breaks away from set mechanism, removing the version unit and break away from the signal that key or drum unit break away from key and send to CPU141, CPU141 also is considered as them invalid and keeps the security schema set condition; Similarly, send to CPU141 even have from the signal of the key that opens the door as the set mechanism that opens the door, CPU141 also is considered as it invalid and keeps the security schema set condition.
And when being in the security schema disarm state, in case have from the drawing unit and break away from key, remove the version unit and break away from the signal of key or drum unit disengaging key when CPU141 sends, CPU141 will be controlled to be to switch on and make it become the latch-release state shown in Fig. 3 (b) (below be called " released state ") according to will the make a plate solenoid 42 of drive division 47 of the signal that breaks away from key from the drawing unit, make it become the released state shown in Fig. 7 double dot dash line according to being controlled to be energising except that the solenoid 92 of version drive division 97 from the signal that removes version unit disengaging key, and make CD-ROM drive motor 65 actions of main drive division 72 enter the released state shown in Fig. 5 (a), thereby make above-mentioned necessary processing operation to carry out according to the signal that breaks away from key from drum unit.
(the 2nd embodiment)

Scanner unit 23 has the inscape same with that shown in Figure 1, be original copy mounting table 10, separating plate 12, preceding original copy conveying roller to 13a, 13b, separate roller 14, original copy output table 15, back original copy conveying roller to 16a, 16b, contact glass 17, fluorescent lamp 18, speculum 19, lens 20, imageing sensor 21 etc., they are mounted and are bearing on the scanner unit framework 150 that constitutes framework.Among the figure of the scanner unit framework of in Figure 13 (a), representing 150 on the diapire on right side, offer and to read the locked hole 150a that Lock Part engages with described later with solid line.
For the ease of the paperboard processing operation of the installation replacing of master reel 26a among the write section 4A that makes a plate (can be with reference to Fig. 1) and master etc. or carry out master in the printing drums 51 and the operations such as paperboard processing of paper etc., can scanner unit 23 be slided on scanner unit frame thickness direction Y3 by above-mentioned reading unit mounting mechanism for Figure 13.That is, scanner unit 23 can carry out shown in the solid line can carrying out shown in the double dot dash line among reading unit latched position that the image of original copy 11 reads and Figure 13 in Figure 13 sliding on arrow Y3 direction between the reading unit non-locked position of operations such as jam processing of the installation replacing of master reel 26a and master 26 etc. and can opening and closing.When being in scanner unit 23 and being positioned at the state of reading unit non-locked position, may see the master 26c after the plate-making on the plate cylinder outer peripheral face that is wrapped in printing drums 51 or use after master 26d plate-making picture confidential information or with its transfer printing on paper and carry out the collection of confidential information.
Scanner locking mechanism 151, as Figure 13 (b) institute detail display, mainly read the securing rod 152 of Lock Part by conduct, extension spring 153 as force application mechanism, and as solenoid 154 formations that read the Lock Part driving mechanism, described securing rod 152 is when scanner unit 23 installation in position are in body frame 2, can be center and embed at one end (upper end among the figure) and to be fastened in the locked hole 150a and scanner unit 23 to be fixed on the position of representing with solid line among the Figure 13 (b) that reads latched position with fulcrum shaft 156, and with locked hole 150a between engage the displacement that freely swings between the position of removing and allowing to represent with double dot dash line among Figure 13 (b) that scanner unit 23 breaks away from from body frame 2, one end card of described extension spring 153 ends on the other end of securing rod 152, apply active force to making an end of securing rod 152 always tend to embed the direction that is fastened among the locked hole 150a, described solenoid 154 only blocks on the other end (lower end among the figure) of securing rod 152 by pin 157 pines spaciously, the active force that can overcome extension spring 153 makes an end of securing rod 152 move with the position tractive that engages of locked hole 150a to removing.
The other end card of extension spring 153 is only planting on the pin on the body frame 2 158.Fulcrum shaft 156 plants on body frame 2.Solenoid 154 is fixed on the body frame 2.One end of scanner unit framework 150 and securing rod 152 be separately positioned on when scanner unit 23 installation in position in body frame 2 and be positioned on the position that can engage with each other when reading latched position.
Above-mentioned original copy among the manuscript reading section 3A is carried the controlled driving mechanisms such as solenoid 154 of motor, scanner locking mechanism 151 to be summarised as original image in Figure 14 and is read drive division 22A.Original image reads drive division 22A and reads drive division 22 with original image shown in Figure 12 and compare, and main difference has been to increase newly the solenoid 154 of scanner locking mechanism 151, and to read drive division 22 identical with original image for other.
Here, the operation principle to scanner unit 23 and scanner locking mechanism 151 describes.At Figure 13 (a), (b) in, when scanner unit 23 is positioned at the reading unit latched position shown in the solid line among Figure 13 (a), the power supply of solenoid 154 is cut off and when being in off-position, will be shown in the solid line among Figure 13 (b), one end of securing rod 152 is the swing of middle mind-set clockwise direction with fulcrum shaft 156 under the active force of extension spring 153, by this swing, embedding is engaged among the locked hole 150a of scanner unit framework 150, thereby scanner unit 23 is locked being fixed on the reading unit latched position, therefore, can't be in the figure to the left arrow Y3 direction slide opening and closing.
On the other hand, when being under the state that scanner unit 23 is positioned at the reading unit latched position, when solenoid 154 energisings make it to become "on" position, will be shown in double dot dash line among this figure, the active force that overcomes extension spring 153 sucks plug 154a, make an end of securing rod 152 leave with the counter clockwise direction that engages of locked hole 150a for middle mind-set releasing with fulcrum shaft 156, thereby an end of securing rod 152 breaks away from from locked hole 150a, make scanner unit 23 can be in the figure to the left arrow Y3 direction slide.
Below, in conjunction with Figure 14 the hierarchy of control of control device 140 peripheries is described.
Control device 140A compares with the control device 140 of the 1st embodiment, and main difference is, substitutes CPU141 and has CPU141A, substitutes RAM142 and has RAM142A and substitute ROM143 and have ROM143A; Other is identical with control device 140, has the microcomputer that possesses not shown timer and not shown input/output port.Plate-making drive division 47A compares with plate-making drive division 47, and main difference is, in above-mentioned each controlled driving mechanism of plate-making drive division 47, has removed the solenoid 42 of drawing unit locking mechanism 38, and other is identical with plate-making drive division 47.
Can have to the signal of CPU141A input: the viewdata signal identical respectively, the angle signal of CD-ROM drive motor 65, from the output signal of the above-mentioned various keys of operation panel 125, from the output signal of home position sensing 69 and from the output signal of security schema position sensor 70 with person shown in Figure 12.Various signals for input, CPU141A carries out calculation process according to the operation program and the associated data that are stored among the ROM143A, and with similarly shown in Figure 12, by CPU141A respectively to above-mentioned each controlled driving mechanism of main drive division 72, to above-mentioned each the controlled driving mechanism that removes version drive division 97, the solenoid 117 of door locked mechanism 114, and via above-mentioned each controlled driving mechanism to plate-making drive division 47A such as not shown various motor drive circuits, and above-mentioned each controlled driving mechanism output action command signal that reads drive division 22A via not shown various motor drive circuits and solenoid drive circuit etc. to original image.
CPU141A will write in the RAM142A from the operation program that ROM143A accesses temporarily.The operation program that writes can be rewritten by the input signal from operation panel 125.In addition, only when the user who comprises operator etc. pressed privacy key 138, the security schema program was written among the RAM142A.RAM142A for example is a buffer storage, and the security schema program that only writes can not lost when the main power source of hole plate print device 1 cuts off yet.For the security schema program that writes in the RAM142A, can it be wiped by above-mentioned secret cancel system, thereby become the security schema disarm state.
Store a plurality of operation programs of each controlled driving mechanism (actuator) action that is used for making hole plate print device 1 among the ROM143A.Among each operation program, have the user and press privacy key 138 and when entering security schema, make the invalid security schema program of input of printing beginning key 127 and examination printing key 128.As ROM143A, with above-mentioned same, can use PROM and EPROM or EEPROM, also they suitably also can be used.
CPU141A (below, for making explanation become simple and clear, sometimes be called " control device 140A ") have a control function as the 1st controlling organization, according to signal from privacy key 138, to the locking mechanism by the setting of each at least one unit (is the solenoid 154 of the scanner locking mechanism 151 in the scanner unit 23 in the present embodiment, the CD-ROM drive motor 65 of the bulging locking mechanism 59 in the drum unit 50, remove the solenoid 92 that removes version locking mechanism 89 in the version unit 82) control, (in the present embodiment scanner unit 23 to stop said at least one unit, drum unit 50, remove version unit 82) from body frame 2, open disengaging.In addition, because in the present embodiment, the version unit 82 that removes that is had has edition locking mechanism 89 that removes that possesses solenoid 92, therefore, also has the control function as the 2nd controlling organization that the solenoid 92 that removes version locking mechanism 89 is controlled.CPU141A (control device 140A), have with the 1st embodiment in the same control function of the 3rd controlling organization, the 4th controlling organization of control device 140.
Below, with regard to the operation principle (operation) of hole plate print device 1A, describe around difference with the hole plate print device 1 of the 1st embodiment.The common action of the hole plate print device 1A that is implemented when not pressing privacy key 138 comes down to that hole plate print device 1 with the 1st embodiment similarly carries out; In the description of relevant plate-making write section 4 and drawing unit 25, as long as substitute it with manuscript reading section 3A and scanner unit 23, and change scanner unit 23 into and be arranged in Figure 13 (a) and read latched position with what solid line was represented, in addition, with control device 140 and CPU141 changes control device 140A into and CPU141A gets final product, therefore its explanation is omitted.
Below, the action that relates to security schema of hole plate print device 1A describes during to use privacy key 138.At first, to being set at security schema but do not append the example of printing, the example that promptly is wrapped in the master 26d after the use that master on the printing drums 51 belongs to need to be keep secret describes.
The user can similarly obtain printed article through making a plate, lock up, try each operation such as printing, printing with above-mentioned.In the occasion of the content need to be keep secret of this printed article, to similarly do not implemented to make a plate, lock up, try each operation such as printing, printing with above-mentioned known to the third party, under the state seen at the printed article of need to be keep secret certainly as the user.After the printing release that need are maintained secrecy, owing to existing confidential information certainly on the master 26d after the use that is wrapped on the printing drums 51, therefore, the user will press privacy key 138 after the printing release that need are maintained secrecy.
When privacy key 138 is pressed, operation panel 125 is with the signal of carrying relevant security schema to set to CPU141A, through the detailed control action same with the 1st embodiment, the CD-ROM drive motor 65 of CPU141A in main drive division 72 sends the action command signal, make the printing drums 51 that stops at original position rotate set angle till shadow shield 68 is detected by security schema position sensor 70, become for example state of drum gear shown in Fig. 5 (b) 60 and driven wheel 61 the two engagement.So, can forbid stoping and extract direction X out to drum unit shown in Figure 4 and drum unit 50 is extracted out and even made it together with drum gear 60 break away from, have the advantage same with the 1st embodiment.
Simultaneously, after writing the security schema program to RAM142A, solenoid 154 outputs that CPU141A does not read drive division 22A to the solenoid 92, the original image that remove version drive division 97 make the command signal of these solenoids actions by each solenoid drive circuit, control each solenoid 92,154 and remain on each latched position, thereby each solenoid 92,154 is failure to actuate and keeps off-position.As mentioned above, read on the latched position, make and from body frame 2, scanner unit 23 extractions to be opened by scanner unit 23 is locked to be fixed on shown in the solid line among Figure 13 (b).And as removing version unit 82, owing to similarly remain on except that the version unit 82 locked states that remove on the version latched position that are fixed on the 1st embodiment, therefore, can't from body frame 2, will and even make it to break away from except that 82 extractions of version unit.Therefore, can prevent to see the confidential information on the plate-making picture (, being erect image sometimes) of the master 26d after the use that is wrapped on the printing drums 51 or it is transferred on the paper and carries out the collection of confidential information in two-face printing device though be generally mirror image.
At the same time, after writing the security schema program to RAM142A, CPU141A and the 1st embodiment are same, the solenoid 117 to door locked mechanism 114 does not send the command signal of moving by solenoid drive circuit, solenoid 117 controlled it is remained on open and close on the latched position, thereby front door 111 can't be opened from framework front baffle 120, therefore, be had the advantage same with the 1st embodiment.
Afterwards, when the user presses printing beginning key 127 or examination printing key 128, operation panel 125 will be carried signal to CPU141A, but because CPU141A recognizes and has write the security schema program among the RAM142A, above-mentioned each controlled driving mechanism output action command signal in main drive division 72 not, therefore, under the control of CPU141A, hole plate print device 1A does not print action and examination printing action.In addition, CPU141A is pressed and when signal is arranged from operation panel 125 inputs, will sends signals to operation panel 125 at printing beginning key 127 or examination printing key 128, makes the message that shows " can not print " on display unit 136.This security schema state, will last till always by above-mentioned security schema cancel system security schema is removed till.In addition, unquestionable, because RAM142A is buffer storage as mentioned above, therefore,, still can keep above-mentioned confidential state even be used for having no progeny to the power switch pass of hole plate print device 1A supply power.
Below, to set security schemas and append the example of printing using privacy key 138, the example that promptly is wrapped in the master 26c after the plate-making that master on the printing drums 51 belongs to need to be keep secret describes.After the printing release of the set printing number that need are maintained secrecy, need to append printing sometimes.When running into this situation, if the user is in order to remove the security schema set condition, will be used in combination with definite key 131 as the numerical key 130 of security schema cancel system, for example with after determining that key 131 is pressed " 6; 7; 8,9 " as password in order, press and determine that key 131 determines to set to " 6; 7; 8,9 ", just there be the signal relevant to send to CPU141A from operation panel 125 with the security schema releasing.So, CPU141A is when the security schema program among the RAM142A of will writing on is wiped, being contained in above-mentioned LED in the privacy key 138 in making extinguishes with expression and is in the security schema disarm state, and, by sending the command signal of moving to main drive division 72, above-mentioned each controlled driving mechanism to the Printing Department 5 of hole plate print device 1A, sheet feed section 7, row's paper portion 8 is controlled, thereby enters the state that can append the printing action.
As user and above-mentioned same, on display unit 135, print putting number, setting print speed printing speeds, as required printed article with print speed printing speed setting key 134 and suitably press when pressing printing beginning key 127 behind the key such as multiplying power key 136c of number with numerical key 130, will with carry out the above-mentioned same operation of printing of locing up, try, the printing number of setting according to put number that appends carries out each operation such as paper supply, printing and row's paper, all process steps constipation bundle of porous printing repeatedly.After the printing release, printing drums 51 will be got back to original position once more.Need maintain secrecy append the printing release after, be wrapped on the master 26d after the use on the printing drums 51 and exist confidential information certainly, therefore, the user will maintain secrecy at need and press privacy key 138 once more after appending the printing release.
In the present embodiment, except in the 1st embodiment, having illustrated, scanner locking mechanism 151 double as are for the replacing of carrying out master reel 26a and paperboard processing of master etc. and the locking mechanism when carrying out sliding opening, in addition, also be the security consideration (for example isolating) during from scanner unit 23 action, be provided with scanner locking mechanism 151 with the drive part headed by the printing drums 51 of rotation.Therefore, preferably, the key of opening that set mechanism is opened in the conduct that allows scanner unit 23 sliding opening from body frame 2 is set on operation panel 125.
