Introduce embodiments of the invention referring to accompanying drawing.In this article, the member of same sequence number has identical effect.

Fig. 2 has showed a skeleton view according to the ink jet recording device of one embodiment of the present of invention, and removable box cassette record-header 2A-2D removably is contained on the carriage 1.Carriage 1 can move along scan track 3, and is installed on the track 11 of its other end.Under belt pulley and belt drives, relative record material 7 is along direction to-and-fro movement shown in the arrow S at drive motor for carriage.When carriage 1 moved, according to image signal, printing ink was through the injection orifice ejection of record-header 2A-2D.Therefrom character, figure or analog are recorded on the recording materials 7.

Record-header 2A-2D is the box cassette with whole print cartridge.Printing ink is sent into the ink-jet district from whole print cartridge.

Record-header 2A-2D can come document image with different printing ink.For example, when colour writes down, can provide yellow, peony, cyan and black ink material to record-header 2A-2D.And the ink-jet of each ink gun partly is the ink gun that utilizes the heat energy ink-jet, and each record-header 2A-2D all has electrothermal transducer.By the heat energy that electrothermal energy converter provides, each record-header all can make the oil film ucleate boiling and cause that steam bubble expands and contraction, thereby printing ink is sprayed from injection orifice, notes image whereby.

In introducing below, when one of member with similar structures or member that all are such, suffix A-D will omit, only use " record-header 2 " or similarly mode express.

According to the image that will write down, transfer roller 12 and 13,14 and 15 preface successively transmits recording materials 7.The guide plate guiding of recording materials 7 transverse edges, the lateral attitude point of recording materials limits.

With regard to each record-header 2, recording image signal transmits through connector 18A-18D from signal wire (flexible cable) 17.Connector 18A-18D is by connector shelf 19 supportings.Connector shelf 19 can move relative to carriage 1 in the M direction.Signal line 17 usefulness screw 20A and 20B are fixed on the limiting plate 21 on the connector shelf 19.One release lever 22 is bearing on the carriage 1 movably.Release lever 22 maintains record-header 2 on definite position when normal operation effectively.Hereinafter on the ad-hoc location of Jie Shaoing, release lever 22 can rotate and RR release record 2.

On carriage 1, has the web joint 23 that engages with release lever 22 and connector clamper 19.On carriage 1, also have the locking jaw 24 and the lock spring 25 that constitute locking device.Locking device with introducing below can under normal circumstances be locked in the record-header position location with release lever 22.When carriage 1 was abutted against the orienting lug 27 of equipment shell 26, when promptly carriage 1 was positioned at carriage rest position (promptly adding a cover the position), locking device was not just placed restrictions on the action of release lever 22 and is made release lever 22 can rotate to the off-position.

When carriage 1 was in rest position A, the ink-jet section of record-header 2 was by capping device 8 lid positions.Capping device 8 has each all cover piece 28A-28D of the ink-jet section of seal record 2 closely.

The housing 26 of equipment has a carriage locking member 29.When carriage 1 was positioned at rest position A, locking member 29 placed between release lever 22 and the carriage 1.When carriage 1 was in rest position A, release lever 22 forwarded on the position of RR release record head, the carriage locking member of introducing below 29 is clipped between the fitting piece 31 of carriage 1 side surface and release lever 22, thereby prevents carriage 1 to move.

Fig. 3 is the carriage 1 shown in Figure 2 and the sectional view of record segment.

In Fig. 3, by the joining surperficial 36-38 and 1 being abutted against of corresponding surperficial 39-41 of carriage of record-header 2 record-header is adorned and gone up in place.

And, press fit in the connector clamper 19 and with its pin of releasing to the protrusion direction 43 by spring 42, make record-header 2 push the left side of Fig. 3 to, press to the surface 39 that joins box cassette record-header 2 relative in the horizontal direction carriages 1 are locked thereby will connect surface 36 and 37.Downward component f in the f power of the inclined surface 44 of pin 43 ends urged record-headers 2 ₁Effect under, make the surface 38 that joins of record-header press to the respective surfaces 41 of carriage 1 and make record-header 2 also locked in vertical direction.

Connector clamper 19 is contained on the connector 18.

When record-header 2 installed on the carriage 1, the effect of the vertical surface 45 of carriage 1 and the vertical surface 46 of record-header was just like simple and easy guide rail.When being in the precalculated position for carriage 1, the district 28 that adds a cover of the ink-jet district 130 of record-header 2 and capping device 8 contacts and covers ink-jet district (being ink discharging surface 131 shown in Figure 2).

Fig. 4 has showed the sectional view of record-header 2 from the situation of carriage 1 dismounting.In Fig. 4, in the time of dismantling record-header 2, at first to connector clamper 19 be moved to right in conjunction with the mechanism of Fig. 5 introduction below with one.When connector clamper 19 moves, guide 45 and 46 connect mutually and prevented moving of record-header 2.Therefore connector 18 from record-header connector 47 separately.Simultaneously, pushing pin 43 also leaves record-header 2.Record-header 2 has just been removed positioning states like this.

When record-header connector 47 unclamps with connector 18, promote 43 and just separate with record-header 2.Record-header just can be dismantled along the R direction like this.

Fig. 5 has launched to unclamp the side view of the mechanism of connector clamper 19, has also showed the mechanism of locking release lever 22 simultaneously.

In Fig. 5, the axle 51 and the connector board of connector clamper 19 are linked to be integral body.Axle 51 is slidingly matched with the hole 52 that forms on carriage 1, and the hole 53 that has a bracket axle 54 with carriage 1 to be slidingly matched on the web joint 23.Therefore, connector holding frame 29 slides carriage 1 front and back relatively.

Release lever 22 can be around bracket axle 54 rotation, and the cam path 56 of formation combines on the teat 55 of web joint 23 and the release lever 22.Therefore along with the rotation of release lever, web joint 23 is carriage 1 move left and right relatively.Locking jaw 24 can rotate around the lock shaft 57 of carriage 1, and under the spring between carriage 1 and the pawl 24 25 promoted, locking jaw can rotate along clockwise direction shown in Figure 5.Therefore, in normal recording operation process, the locking section 59 that locking jaw 24 forms is fitted with the locking section 60 on the release lever 22 can prevent that release lever 22 from rotating.

Fig. 6 is the side view of release lever in release conditions.When carriage 1 during at rest position A (seeing figure one), the guide surface 61 on the locking jaw 24 is seen Fig. 1 by the orienting lug 27(that is pasting on the housing 26), and the tension force that locking jaw 24 overcomes locking spring 25 rotates by counterclockwise along inclined surface.

When locking jaw rotated, the locking section 59 of (see figure 6) on it thrown off and applying between the two removed from the locking section 60 on the release lever 22, thereby release lever can be rotated.

In Fig. 6, represent the position of the permission dismounting record-header 2 of release lever 22 with solid line, with dashed lines table release lever 22 has gone to the position of lock reord head 2.

When release lever 22 when latched position goes to the off-position, the camming action that prominent part 55 and eccentric orfice are 56 makes to constitute holistic connector clamper 19 with web joint 23 and push (to Fig. 6 right-hand) open from the record connector 47 of record-header 2

When connector clamper 19 moved on to rear portion (shown in Figure 6 is right-hand), connector 18 was removed from record-header connector 47, saw Fig. 3 and promote 43() just leave record-header, thus make record-header 2 detachable.

Therefore, the release movement of head cartridge card release lever can only be only possible when record-header is positioned at non-record position (promptly adding a cover the position).Therefore, even when the paper jam phenomenon takes place, record-header can not be changed on record position.This has just prevented that recording materials from contacting with the accident of record-header, thereby has also just avoided by the damage that contacts the record-header that is caused.And prevented the dissipation of printing ink in equipment.

The locking releasing mechanism of having introduced is to have the mechanical type that uses the carriage scanning motion, but this also can be replaced by electric control gear.Such example is seen Fig. 7.

In Fig. 7, the arm 66 of locking jaw 24 joins with the coil axes 68 that installs to the coil 67 on the carriage 1.The power on/off of coil is that the locking released movement of release lever 22 is controlled by automatically controlled circuit 69.Carriage 1 disposes a detecting device 70.So the photosensor 71 that is arranged on the apparatus casing side can detect carriage whether on the precalculated position.

In the signal entry-line 69 from photosensor 71.When box card installation bracket is positioned at when adding a cover the position, control circuit drive coil 67 and make locking jaw 24 in Fig. 7 along rotating clockwise, thereby realize the release lever 22 of locking being unclamped in the mode of similar previous embodiment.

Go to the off-position iff release lever 22, carriage 1 still can be shifted to recording areas.Therefore, although just can change record-header adding a cover the position, when carriage 1 was positioned at recording areas, it also was possible that record-header is installed.Therefore, the secure context of installation record-header is not very good (being emitted to the medium aspect of equipment from the infringement and the printing ink of record-header).From this point, when release lever 22 was in the off-position, the equipment of this embodiment also was provided with a carriage locking member 29(who fits with the applying section 31 of release lever 22 and sees Fig. 2 and 6).This measure has prevented that carriage 1 from adding a cover moving to the direction of scanning on the position.

In this embodiment, when carriage 1 was positioned at rest position A, the locking member 29 of carriage 1 entered into the gap between the joining section 31 of the side surface of carriage 1 and release lever 22.When therefore release lever being gone to the off-position, because of 29 holders of carriage locking member are gone into to only having made carriage moving to the direction of scanning between carriage 1 and the joining section 31.

In this way, just can be only when carriage 1 is positioned at static position dismantled and assembled record-header 2.When dismounting record-header 2, reinstate the tray moving arrester that prevents that carriage 1 from moving to the direction of scanning.

According to the above-mentioned embodiment that relates to the ink jet recording device that uses detachable record-header 2, during arbitrary position beyond carriage is positioned at rest position A, the record-header on carriage 1 is blocked.Only when carriage 1 was in rest position A, the charging crane of record-header could operation.According to the connecting each other of the charging crane of record-header 2, the starting tray moving arrester moves to prevent carriage 1.Prevented therefrom by the damage that contact the record-header that caused of record-header 2 with recording materials 7 or analog.And, the printing ink dissipation phenomenon that vibrations caused when also having prevented loading and unloading record-header 2.In addition because of guaranteeing that record-header 2 adds a cover the evaporation of having avoided printing ink giving allocation.

Can replace mechanical hook-up (carriage locking member 29 and joining section 31) with automatically controlled picture signal moves along the direction of scanning from adding a cover position (being rest position A) to prevent carriage 1.

In Fig. 8, carriage 1 has a position probing 71, and whether it detects carriage 1 with photosensor 72 and giving on the allocation.Dispose a motion that detects between the off-position of release lever motion on the release lever 22.When detect carriage 1 be positioned at give allocation (being the rest position A of Fig. 1) and also with release lever carry out field-strip (when promptly rotating to the off-position, with control circuit 74 drive coils 75 so that coil axes (movable axle) 76 enter in the conjugate foramen 77 on the carriage 1.

When carriage 1 was positioned on the predetermined rest position, the conjugate foramen 77 of carriage 1 was positioned on the position that faces coil axes 76.

Therefore, when carriage 1 is positioned at the precalculated position, coil axes 76 is entered in the conjugate foramen 77, thereby prevent moving of carriage 1 and lock it on the rest position with regard to making coil 75 excitation.

Therefore, use structure shown in Figure 8, ink jet recording device also can be only be at carriage 1 just can make the charging crane of record-header 2 unclamp when being predefined on the rest position.And carriage is on rest position the time, by with the connecting each other of the loading and unloading action of record-header 2, but also driven bracket moving arrester 76 and 77 goes to prevent moving of carriage 1.

Therefore, the same with aforesaid those embodiment, embodiment shown in Figure 8 can prevent that also contacting the record-header that is caused with the accident of recording materials by record-header 2 damages.In addition, also prevented the printing ink dissipation phenomenon that causes by the vibration that loading and unloading record-header 2 produces.And, owing to can guarantee record-header 2 to be added a cover, therefore also prevented the evaporation of printing ink in the precalculated position.

As previously mentioned, latch mechanism by means of release lever makes the loading and unloading of record-header 2 only add a cover position or non-record position at rest position A() carry out, perhaps by prevent that the mobile carriage 1 that makes that carriage is done on the relative scanning direction from not moving in record-header replacing process when release lever rotates.Thereby the damage of record-header or the dissipation of printing ink have been prevented.But also the special damage that has prevented the ink ejection face of record-header effectively.

Referring to Fig. 9, when release lever was positioned at release conditions, the release lever of charging crane was parked in shown position.So the inner edge 22d of clamp segment 22c has constituted the guide of the record-header guiding surface 21 of guiding ink jet print head 2.Inner edge 22d is parked in and leads table from carriage promptly highly is H to the vertical range of face 1g ₁The position on.Height H ₁Greater than the ink-jet side surface 2B of the record-header 2A of record-header 2 height H to 21 of ink gun guiding surfaces ₂The radius of turn of the inner edge 22d of the clamp segment 22c of release lever 22 should be selected as much as possible for a short time, thereby can not meet print cartridge 2B in its rotary course, and when release lever 22 was parked in the off-position, inner edge 22d was parked in as close as possible position of inserting section 1a.

When discharging charging crane, the prodger 2c that the record Head Section 2A of record-header 2 is housed on it is inserted into the insertion district 1a of carriage 1, or when prodger when there comes out, inner edge 22d and ink jet print head guide surface 21 are close together mutually (owing to H ₁And H ₂Between height relationships), at carriage, in guide surface 1g and the scope that the basal surface right-hand member of prodger 1a contacts, the basal surface of prodger 1a tilts with respect to carriage guide surface 1g.Therefore, prevented that the ejection side surface 2B that writes down Head Section 2a from contacting with the whole surface of carriage guide surface 1g.Preventing the slip between ejection side surface 2B and the carriage guide surface 1g according to this mode, thereby protected the injection orifice on the surperficial 2B of ejection side.

In addition, the clamp segment 22c that is used to drive the release lever 22 of charging crane is used as the guide of the guide surface 21 of guiding ink gun, and therefore, the injection orifice on the 2b of ejection side surface is protected and does not increase the machine-building expense.

Below another embodiment will be described.

See Figure 10 and 11, the charging crane 131 of this embodiment has a grooved, guide arm 134.One of its overhang bracket at the side surface on the carriage 124 and on the 124h outstanding turning axle 124l with go up on another outstanding turning axle (not shown) on the relative opposite side surface (not illustrating) of side surface 124h, be used on J direction or reverse direction, rotating respectively.One arm-type gear 134a is arranged in the end of guide arm 134, and it is meshed with rod-type gear 132b on the release lever 132.

When release lever 132 was positioned at illustrated fixed position, the arm guide section 134b of guide arm 134 was positioned under the box district 122b of ink jet print head 122.When release lever 132 from the fixed position when the G direction goes to the off-position that dotted line represents, because the engagement of rod-type gear 132b and arm-type gear 134a is rotated with release lever 132.Guide arm 134 along J direction rotation up to going on the position that dotted line represents.

See Figure 11, when charging crane 131 was in the off-position, guide arm 134 stopped on the shown in the drawings position.Arm-type guide 134b has constituted the guide of the ink gun guide surface 122l of guiding ink gun 122.The vertical range that arm-type guide 134b has been parked in carriage spigot surface 124g is L ₁The position on.This height L ₁Greater than from the ejection side surface 121a of the record Head Section 121 of ink gun 122 to the distance L ink gun guide surface 122l ₂In release conditions, arm-type guide portion 134b goes to as much as possible near being contained in the 122b place, box district of the ink gun 122 on the carriage 124 and being parked in there.

When in release conditions.With charging crane 131 during from carriage 124 loading and unloading ink guns 122, arm-type guide 134b(guide section) and ink gun spigot surface 122l be close together mutually, be similar to the embodiment of Fig. 9, in carriage spigot surface 124g and scope that the right-hand member (among the figure) of the basal surface of prodger 122a contacts, prevented that the ejection side surface 121a of record-header 121 from contacting with the whole surface of carriage guide surface 124g.Therefore, prevented the friction between ejection side surface 121a and carriage spigot surface 124g, so protected ejection side surface 121a and injection orifice.

To narrate another embodiment.In ink jet print head 2 in conjunction with Fig. 9 explanation, the box 2B that is used to hold the printing ink that will be delivered to record Head Section 2A becomes an integral body with record Head Section 2A, in the present embodiment that will illustrate, ink jet print head does not have a kind of as shown in Figure 9 whole box.The substitute is, the box that is used for holding the printing ink that will send into the ink jet record head Head Section is arranged on the main assembly parts of ink jet recording device.

Referring to Figure 12, the connector clamper 147 of carriage 144 has a unitor 155.Unitor 155 links to each other with pipe 155a, and pipe 155a links to each other with the box (not shown) of the printing ink that is used to hold the record Head Section 141 that will send into ink gun 142.From another point of view, ink gun 142 has a record-header unitor 142m who is positioned at the position that aligns with main assembling unitor 155.Transmit passage by a printing ink, record-header unitor 142m is communicated with (not shown) with record Head Section 141.

The prodger 142a of ink gun 142 is inserted among the receiver 144a of carriage 144, the release lever 152 of charging crane goes to the fixed position and is parked in there, connector clamper 147 moves along the L direction, thereby the main assembling unitor 155 on it is interconnected at together mutually with record-header unitor 142m.Printing ink in the print cartridge is through pipe 155a, and the master assembles unitor 155, and the such order of record-header unitor 142m and printing ink transfer passage enters into record Head Section 141.

The charging crane that replaces this embodiment can be used for carriage 144 with the mechanism with guide arm of narration in Figure 10 and 11.

Because the top structure of narrating embodiment will illustrate significant effect below.

When discharging charging crane when allowing ink jet head cartridge to carriage, be used to guide the guide section of the ink gun spigot surface of ink gun to be in such position, the relative carriage spigot surface in ejection side surface that is ink gun is obliquely installed, like this in the scope of guide section guiding ink gun spigot surface, prevented that effectively the surface that ejection side is surperficial and the carriage spigot surface is whole from contacting, therefore, prevented sliding contact between ejection side surface and carriage guide surface.The result is, with having protected ejection side surface and injection orifice once simple structure.Therefore, avoided injection orifice, in addition, also avoided the unfavorable phenomenon of scrapping at the lip-deep waterproof overlayer of ejection side by the unfavorable phenomenon that impurity on the carriage guide surface stops up.

In addition, the clamping element that is used to handle the release lever of charging crane is used as the guide of guiding ink gun guide surface, therefore, need not increase manufacturing expense.

In Figure 13, have openable door (Qianmen) 220 in the front portion of ink jet recording device.

Door 220 has a prodger 241, and the main assembly parts of recording unit have a section 142(hole that cuts some of closing of opening with prodger 241, breach).Adding a cover the position, cutting a part of section 242 and carried out more changing jobs of record Head Section 1A-1D record-header effectively.

At the locking member 221 of the back of door 220 projection one formation locking device, it cooperates with the latch mechanism of the main assembly of equipment, can place restrictions on the open and close of door.

The effect of locking device be prevent door 220 from open mode or closed condition to another state transformation.Will be described herein-after locking device, when door is closed, can prevent effectively that the operator is optionally with door 200 open and close.For example, when starting main switch, door 200 arbitrarily open and close; And when main switch was not started, door 200 can not open or close.

Figure 14 A, 14B and 14C are the Section Views of the II-II line along Figure 13, have showed the structure and the operating process of this locking device.Figure 14 A-14C has showed that the door 200 when connecting corresponding to equipment master assembly parts main switch transfers to the situation of closed condition from opening.When main switch closed, under the signal effect of controller, coil 223 just held moving iron 224, thereby makes door be in locking state.

In the action of closing door 200, tight device moves locking member 221 in the upper edge of direction shown in the arrow.See Figure 14 A and Figure 14 B.Locking member 221 is pushed down the prodger 225 of spring 226 supportings, and moves along this direction, till it arrives the off-position shown in Figure 14 C.On this off-position, spring 226 makes prodger 225 combine with groove on the locking member 221, thereby door 220 had before been closed.In addition, when this state, locking member 221 is pushed down door sensor 222.Make the controller of the main assembly parts of equipment detect the situation of closing of door 220 therefrom.Owing to trigger the starting main switch, coil 223 still holds moving iron 224, even also is like this in the state shown in Figure 14 C.Therefore, moving door 200 optionally at this moment.Therefore, as long as main switch is in on-state, door 200 is random open and close just.

At door 200 closed fully, and under the situation that main switch has disconnected, coil 223 unclamps and moves iron 224 because of losing excitation.This situation is shown in Figure 14 D.Under the spring tension effect, release member 224 outside projections and the pawl section of displaceable member is entered in the conjugate foramen 231 on the locking member 221 and locking member 221 is pinned.The opening and closing of door 200 have been prevented therefrom.

After main switch connection, door 200 are opened, be disconnected again as main switch, displaceable member 224 can outwards be given prominence to and prevent the mobile of locking member 221, sees Figure 14 E, therefore, has prevented closing of door 220.Therefore, in this embodiment, only when main switch was positioned at on-state, door 220 could be opened or close.

Figure 15 is the system-wide block scheme of the recording unit of this embodiment.There is the controller 300 of a whole pen recorder of control in this system.This controller 300 comprises that a form is microprocessor or similarity piece CPU(central processing unit for computer) 301; Will be in conjunction with Figure 16, the various data of storage of 17,18 and 19 explanations and the ROM(read-only storage of CPU control program) 302; And RAM(random access memory that can be used as the workspace of CPU301 and be used for temporarily storing various data) 303.

CPU301 receive start-recording signal from recorder run key 304, from the door of door sensor 222 close detection signal, from the paper sheet delivery signal and the similar signal of paper sheet delivery sensor 216.

From another point of view, CPU301 response input signal is with the control various piece, and also basis is carried out the picture record operation effectively from the picture intelligence or the similar signal of main frame.

CPU301 produces the coil control signal of response detection signal or similar signal and the drive source 305 of control coil, so the mode of operation of coil is controlled.

When CPU301 identification paper stops up or during from the basic detection signal of output transducer 216 or similarity piece, connects paper and stop up pilot lamp 306.

In the record operation process, image or similar signal according to main equipment, CPU301 control motor driver 307 is with the motor of control as carriage mobile motor 308 and so on, the picture signal of sending according to main frame or similar means simultaneously, the operation that also reliable controlling recording head driver 308 removes a controlling recording 201A-201D.

Figure 16 and 17 has showed the master routine of above-mentioned ink jet recording device control procedure and the process flow diagram of interrupt routine.

In Figure 16, when the main switch of activated equipment, at step S ₁On, to CPU, RAM or the similarity piece initial alignment of controller (not shown).After finishing initial alignment, at step S ₂On, the locking state that discharges door 200 begins to allow interrupt routine.Particularly to from the conjugate foramen 231 of locking member 221, draw back and decontrol the locking state that locking member is promptly cancelled door 200 so that will move the pawl section of iron 224 to hold moving iron 224 coil 223 excitation.Then, allow the operator to open door 220.

At step S ₃, door 220 unlatching is detected by door sensor 222, if door 220 is opened, recording operation just can not begin, and then in the closed-loop path, carries out detecting operation continuously, closes to extremely up to door.

When door 220 has been closed, at step S ₄, record-header 201 has covered capping device 212.After adding a cover, the operator is at step S ₅Can depress initiating key.

After when depressing recorder run key, at step S ₆Carry out recording operation.Behind the recording operation of finishing the predetermined quantity paper, at step S ₇Add a cover for record-header 201.After adding a cover, operation turns back to step S ₅,, promptly wait for and press initiating key next time to prepare the next record operation.

Referring to Figure 17, will narrate interrupt routine.When door 220 is opened, door sensor 222 just examine survey this situation in the time, the CPU of controller requires to open circuit, if the operation of the master routine of Fig. 6 is at step S ₃Just allow when carrying out afterwards to open circuit.Therefore, be converted to the operation of interrupt routine shown in Figure 17 immediately.

In Figure 17, at step S ₈, during recording operation, to open as door 220, recording operation just stops.Particularly, stop record-header 201 is sent driving pulse and ink-jet pulse.In addition, also stop stepper motor 308 is transmitted driving pulse to stop the motion of carriage 202.Even be not to write down shut-down operation during recording operation, this also is harmless to this equipment in this record shut-down operation.At step S ₉, before turning back to master routine, the step number of master routine becomes " 3 ".Because the variation of step number, after the operation from interrupt routine turned back to master routine, master routine was operated immediately from step S ₃Beginning.

Because above-mentioned interrupt routine is always added a cover operation after door 220 opens or closes.

If door 220 opens or closes,,, stop up so can identify paper owing to paper signal before the recorder run key under admiring just exists in the paper sheet delivery sensor 216 by the 216 detection record materials of the paper sheet delivery sensor among Figure 15.Therefore, the paper among Figure 13 being stopped up lamp 219 lights to impel the operator to remove recording materials and to trigger main switch again.

According to the above embodiments, only main switch is turned off or door 220 is when being opened during writing down during writing down, and record-header 201 is positioned at the situation of not adding a cover the position and just can takes place.Therefore, except the situation that the operator is meant to do like this, record-header 201 is can not be in do not add a cover locational.

Therefore, according to this embodiment, almost can avoid record-header 201 not add a cover fully and stay the unfavorable phenomenon in somewhere.Therefore, the ink solidification phenomenon that can avoid the carelessness owing to the operator to cause mistake to cause.

Figure 18 shows according to the tight mechanism of door lock of another embodiment and its operating process.Figure 18 is the cut-open view of the same section represented with Figure 14.

Figure 18 A shows main switch when not triggering, and locking member 221 is positioned at the side state of opening.Figure 18 B shows main switch when not triggering, and latch mechanism 221 is positioned at the state of off-position.Figure 18 C shows main switch and is positioned at on-state, and latch mechanism 221 is in the intermediateness between the opening and closing state.

In these figure, the fitting piece 227 that is fabricated from iron rotatably is contained on the main assembly parts of recording unit round pivot 229.Fitting piece 227 is being pushed away by spring and is stretching to outside the surface that locking member passes through thereon, sees Figure 18 A.

Fitting piece 227 with a stop surface 227A and a slidingsurface 227B can prevent that the closure of locking member 221 from moving, but because its structure, it allows the unlatching of locking member to move.

From another point of view, locking member 221 has the configuration of a prodger corresponding to fitting piece 227 (pawl).More particularly, this configuration allows it to move and prevent that it from moving at approach axis to opening direction.It also comprises a groove that is meshed with fitting piece 227 232 on make-position, see Figure 18 B.

Contiguous fitting piece 227 places are provided with a coil 230.The signal that coil 230 response CPU come overcomes the spring force of spring 228 and holds fitting piece 227 and with its withdrawal, thereby does not hinder locking member 221.Be similar to the foregoing description, this also provides a door sensor 222.

When door 220 was closed, locking member 221 was positioned at the position shown in Figure 18 B, as long as main switch is in on-state, locking member 221 just promotes door sensor 222, and therefore, CPU is go out 220 closure of identification just.

If from shown in Figure 18 B on the other hand, when door was positioned at off-position, main switch was in on-state, solenoid 230 loses excitation; So fitting piece 227 stretches out.Therefore, locking member 232 is positioned at off-position.

Yet, when locking member 221 is being opened direction and is being moved, but owing to fitting piece antagonistic spring 228 power are withdrawn, then locking member can move on to the right, door 220 is opened, and locking member 221 moves to Figure 18 A condition from Figure 18 B state and just door can be opened through Figure 18 C state.When door 220 is opened, fitting piece 227 is stretched out outside the surface that locking member passes through through spring 228 effects.So just prevented the motion of locking member 221 on closing direction (left).In other words, prevented that door from 220 closing.

When main switch is in on-state, when door 222 is closed, the non-triggering of coaxial main switch, situation was the same when door 220 was opened, till door 220 is opened fully.

Under the main switch triggering situation, when door sensor 220 is opened, the unlatching of CPU detecting gate 220, coil 230 maintains the foment that holds fitting piece 227, depresses door sensor for extremely up to the closing function of door 220.

Therefore, when main switch is in on-state, when door 220 is closed, can open and close again door 220.

In above-mentioned control mode, in the present invention, also only be when main switch is positioned at on-state, door 220 just can be closed.

Figure 19 and 20 is used to control according to the master routine of the operation of equipment of the embodiment of Figure 18 and the process flow diagram of interrupt routine.

In Figure 19, when the main switch of trigger recording equipment, be used for CPU, the RAM of controller (not shown) or the initial alignment of similarity piece, operate in step S ₁₁Carry out.After initial alignment is finished, at step S ₁₂Carry out open-circuit operation.

At step S ₁₃, whether door sensor 222 recognitiion gates 220 are opened.As door is to open, and operation just enters step S ₁₅In this step, coil 230 is in position fitting piece 227 states of inhaling, up to door 220 be closed, at step S ₁₃Till detection step on the circuit is finished.

On the other hand, if door 220 is closed or triggered the buttoned-up words of starting time inside door at main switch, operation enters step S ₁₄, in this step, coil 230 loses excitation.At step S ₁₆In, record-header 201 adds loam cake.After adding a cover, enter step S ₁₇, wait for that the operator depresses recorder run key, and enter next step operation.

Along with depressing of recorder run key, in the operation of step 18 opening entry.Behind the paper that has write down predetermined number, record-header adds loam cake on step 19.

Finish add a cover after, operation turns back to step 17, to prepare recording operation next time, promptly waits for and presses recorder run key next time.

Introduce interrupt routine shown in Figure 20 below.Door 200 is opened, and door sensor one detects this situation, and the CPU of detecting device just carries out interrupt routine.If the operation steps in the master routine of Figure 19 is at step S ₁₃Afterwards, just interruption logging immediately makes control operation enter into the interrupt routine of Figure 20.

In Figure 20, at step S ₂₀On, during recording operation, door 220 1 is opened, and recording operation just stops immediately, but also thereby the transmission pulse that stops to be used for the driving pulse and the ink-jet pulse of record-header 1 and stop to be used for stepper motor 208 makes carriage 202 stop to move, even recording unit no longer is in the recording operation state.This recording operation controlled step can not cause deleterious effect to recording unit.At step S ₂₁, before operation turned back to master routine, step number became " 13 ".Conversion by step number just turns back to master routine from interrupt routine, at master routine S ₁₃Step begins control operation immediately.

Because above-mentioned interrupt routine, no matter door 202 be shut or open, total energy realizes adding a cover action.

During recording operation, open or shut as door 220, paper sheet delivery sensor 216 total detection record materials.Because before pressing recorder run key, recording materials just are present in a certain position of paper sheet delivery sensor 216, so sensor can detect the paper latch up phenomenon.Therefore, the paper obstruction lamp 19 of lighting Figure 14 takes out recording materials to trigger main switch again to impel the operator.

Remarkable result is described as front embodiment similarly, more particularly, does not only trigger or when door 220 was opened during recording operation, record-header 201 just can be in the situation of not adding a cover at main switch during the recording operation.Therefore, except the operator has accident, record-header can not be in the situation of not adding a cover.

Therefore, almost can eliminate record-header 1 fully and be in rough sledding in the situation of not adding a cover.Therefore, the ink solidification phenomenon in the record-header that mistake caused 201 that has prevented to cause by operator's carelessness.

In addition, according to present embodiment, even under the situation that main switch does not trigger, also allow door 220 to open.Therefore, the contrast previous embodiment can more safely be replaced record-header 1.In addition, can reduce the quantity of the structural member of the latch mechanism that is used for door 220, so also just reduce the machine-building cost.

In the aforementioned embodiment, 4 record-header 1a-1d are used in the color ink-jetting record equipment.Yet, the present invention also is applicable to have single record-header (single ink-jet district) carries out in the equipment of monochromatic record, also being applicable to can be in same color, no matter write down what ink jet recording device of the ink jet recording device of tone or another record-header quantity with a plurality of record-headers that different densities is provided.

Removable record-header 201A-201D can be the ink sprayer that comprises separation and be connected through unitor and pipe.The record-header form of print cartridge also can be to have ink sprayer and do not have the record-header form of print cartridge or the record-header form of a whole ink sprayer and print cartridge is arranged.The present invention is applicable to the ink jet recording device of continuous recording type, this equipment has one and is contained on the carriage record-header that can move along recording materials, the present invention also is applicable to the line ink jet recording device, and this equipment uses line-type recording head can provide good equally effect with the whole or major part of the record width that covers recording materials.

When door is opened, prevent that the security of record-header from non-record position (adding a cover the position) to recording areas from having obtained guaranteeing further.

The moving limiting device of below that explanation is relevant with the opening and closing of door record-header.

Figure 21 shows moving arrester 408.In the rest position of carriage 406a, a grooved moves and prevents that part 408a from can rotate round axle 408b.Under the effect of extension spring 408c, the mobile part 408 that prevents is pushed the c direction of Figure 21 to.Its braking contacts by its bottom and prevents part 408d and realize.In the mobile end of part 408a that prevents one awl part 408a is arranged ₁, when the precalculated position, a conjugate foramen 408c is arranged on the basal surface of carriage 406a.

With the opening and shut under the relevant situation of lid, handle and to prevent part 408, more particularly, see Figure 22, recording unit has a lid 412, take off at main assembly parts 411 places that its structure can make it slave unit.The inside surface of lid 412 has a prodger 408f.When lid 412 closed, prodger 408f was pushing away the end 408a that prevents part 408a ₂When lid 412 takes off, remove the backup state.

Therefore, shown in the dot-and-dash line of Figure 22, when door 412 was closed, prodger 408f was pushing away end 408a ₂, under this backup effect, prevent that part 408 from rotating along the d direction round axle 408b, so that tapering point 408a ₁Throw off with conjugate foramen 408e.Like this, carriage 406a just can move along slide rail 406c, thereby can carry out recording operation without barrier.

On the other hand, when opening for changing record-header 406b or similar purpose when covering 412, prodger 408f no longer backup prevents the end 408a of part 408a ₂So, under the tension of spring 408c, prevent that part 408a from just rotating to till the stop block 408a that reclining.(position shown in Figure 21 dot-and-dash line) is on the original position if carriage 406a is arranged in rest position, represents Tapered Cup 408a with solid line ₁Front end (leading end) combine with connect apertures 408e on the carriage 406a and the situation of locking.Therefore just prevented carriage 406a moving along slide rail 406c.And, prevented that also when record-header was changed operation, unexpected moving appearred in carriage 406a.

If, owing to unexpected power failure or similar phenomenon occur the lid 412 of carriage to be opened, when carriage 406a has been parked in a certain position beyond the rest position, the carriage bottom can be along Tapered Cup 408a ₁Depress and prevent part 408a.When carriage 406a has moved on to rest position, under the effect of spring 408c tension force, Tapered Cup 408a ₁Enter into connecting hole 408e, thereby carriage 406a is locked on the rest position.

Like this, when lid 412 when opening, move the unlatching that prevents part 408a and lid 412, cooperate, action can prevent that the carriage that is parked in rest position from moving, cover 412 when closing, remove immediately placing restrictions on that carriage 406a moves.Therefore, changing record-header 406b or removing in paper jam operation or the similar operations, carriage 406a can by mistake not move.

When recording chart 402 blockage phenomenon, opening device 409 is opened conveying roller 404a and pinch roll 404b and conveying roller 404c and is separated with pinch roll 404d, in order to the work of removing paper jam.

See Figure 23, hook 404j ₁And 404j ₂Be fixed to a 409a ₁With axle 409a ₂On.Hook 404j ₁And 404j ₂Having can be around axle 409a ₁And 409a ₂The complete gear parts 409b of rotation ₁And 409b ₂One of them gear parts 409b ₁By a cam-like gear 409c and tooth bar 409d engagement, and another gear parts 409b ₂Direct and tooth bar 409d meshes.

Operating rod 409e is contained in a 409a ₂On.Therefore, when operating rod 409e rotates on Figure 23 e direction, hook 404j ₂Along throwing off pressuring shaft 404e ₂Direction rotation, simultaneously, tooth bar 409d slides on the f direction.Therefore, hook 404j ₁Along g direction rotation, thus with pressuring shaft 404e ₁Throw off, removed conveying roller 404a and pinch roll 404b, and the pressure between conveying roller 404c and the pinch roll 404d.Prevent that opening tool 40/a is in the dotted line position of Figure 23.

At this moment, arm 404f ₁And 404f ₂By spring 404i ₁And 404i ₂Pushing away and keeping 404f respectively ₁And 404f ₂Part on the position that touches bolster 404h.In addition, when operating rod 409e when the e direction is rotated, be contained in cam-like gear 409c ₁On the cam 409f of arm 409c rotational fixation on bolster 404h, carry out guide 409g ₁With pinch roll 404b.Its situation as shown in figure 23.

Like this, heighten with regard to the aperture that makes paper transport device 404, and paper jam removing work can be carried out smoothly, and paper 402 is disposed from connecting to send the passage.

In state shown in Figure 23, in paper transport device 404 open modes.Last guide 404g ₁Enter carriage 406a scanning area with pinch roll 406b.This means, be parked in the outer arbitrary position of stationary state A as carriage 406a, as operating rod 409e being opened last guide 409g ₁Can interfere with carriage with pinch roll 406b.It seems that from this point equipment of the present invention has only when carriage 406a is in rest position, paper transport device just can be opened.

When carriage 406a was positioned at other position, paper transport device can not be opened, and this is guaranteed by device 410.

See Figure 23, opening protecting apparatus 410 comprises the L type unlatching guard member 410a that rotatably is contained on the 410b.When opening protecting apparatus 410a was positioned at position shown in Figure 23 solid line, the end of tooth bar 409d nestles up opened guard member 410a.The end of coupling shaft 410c rotatably is contained in to be opened on the guard member 410a, and L type locking member 410d is contained in the other end of coupling shaft 410c.When carriage 406a moved on to rest position, locking member 410d contacted with the bottom of carriage 406a, so that coupling shaft 410c is slided along the h direction among Figure 23.

Therefore, when carriage 406a is positioned at a certain position outside the rest position, opens guard member 410a and be positioned at position shown in Figure 23 solid line, with the slip of restriction tooth bar 409d in the f direction.Therefore, mobile operating rod 409e is possible on the e direction, so prevented the unlatching of paper transport device 404.

When opening that paper transport device 404 carries out that paper jam is removed or during similar work; move on to the motion of rest position by carriage 406a; coupling shaft 410c slides on the h direction; open guard member 410a and move on to position shown in Figure 23 dotted line; therefore; tooth bar 409d becomes slidably state, thereby available operating rod 409e opens paper transport device 404.At this moment, prevent moving of carriage 406a with aforesaid moving arrester 408.

As mentioned above, according to the present invention, when carriage 406a was positioned at rest position, paper transport device 404 just can be opened.When carriage 406a is positioned at other position, owing to there being the protective device 410 of unlatching to make it and to open.So can prevent the damage of carriage 406a or record-header 406b or similarity piece.
