The specific embodiment

Explain one embodiment of the present of invention below with reference to accompanying drawing.Below, at first,, explain summary according to the ink-jet printer (hereinafter being referred to as " printer ") 1 of conduct of the present invention " recording equipment " or " liquid injection device " example referring to figs. 1 to 4.Hereinafter, Fig. 2 is referred to as " downstream " of paper transportation path to right (front side of printer), and direction (rear side of printer) is referred to as " upstream side " left.

In Fig. 1, printer 1 comprises apparatus for sheet feeder 2, places wherein with the posture that tilts as the recording paper (record sheet) (hereinafter being referred to as " paper P ") of " recording medium " or " destination media " example.The front side of this equipment comprises accumulation device 13, accumulation device 13 is in open mode (Fig. 3) and closed condition (Fig. 1) selectively, be used for piling up paper P by opening towards the front side of equipment in open mode, described closed condition is closed to extend in the direction of perpendicular by pivotal action from open mode.The bottom of lower case 17 forming devices.Accumulation device 13 is made up of accumulation device main body 14 and secondary accumulation device 15, and forms and can rotate around the pivot 14a of accumulation device main body 14 (Fig. 5) pivot.Secondary accumulation device 15 forms the constructional surface of piling up paper P by extracting out from accumulation device main body 14 under its state of opening towards the printer front side.

The outside of the equipment of printer 1 covers by box-like housing 11, and the top at housing 11 centers is provided with door closure 12, is used to send out the replacement operation of print cartridge etc., and its outward appearance is by apparatus for sheet feeder 2, accumulation device 13, and housing 11 and door closure 12 are formed.

Below, main reference Fig. 2 and 5 explains the details of paper transport path in detail.In Fig. 2, feeder 2 comprises paper storing box 21, feed rolls 23, reduction roll 27 and guiding roller 25,26, so that one by one paper P (first recording medium) is fed into the conveyer of being made up of driven roller 33 and driven voller 34, thereby sends paper P to ink jet print head 39 further.

The paper sensor 4 (paper detector) that detection paper P passes through is in the driven roller 33 of trip side disposed thereon on the transfer path of recording medium and near the position the driven voller 34.Controller 7 shown in Figure 5 is suitable for receiving the control signal of sending from the command signal source that comprises the sensor, carry out apparatus for sheet feeder 2 thus, the conveyer of forming by driven roller 33 and driven voller 34, record head 39, and each operation of ejector (back description).Paper sensor 4 and controller 7 do not show in the accompanying drawing except Fig. 5.

Hand switch shown in Figure 4 activated so that carry out the feeding of the feeding operation of paper P (first recording medium) and pallet T (hereinafter describing)/launch operation.Hand switch 5 does not show in the accompanying drawing except Fig. 4.

More particularly, paper storing box 21 is plate-shaped members, can rotate around pivot center (not shown) pivot at an upper portion thereof.By pivotal action, be supported on paper P on the paper storing box 21 and enter pressure with feed rolls 23 and contact, or paper P and feed rolls 23 are separated.Feed rolls 23 is D shape parts in its side view.The curved portions of the feed rolls 23 that contacts with paper P pressure with same paper feed to the downstream.Transmitting in the process of paper P by driven roller 33 and driven voller 34, chain of command does not transmit load to the flat of the feed rolls 23 of paper P so that do not produce.

Reduction roll 27 is suitable for contacting with the arch section pressure of feed rolls 23.When paper P of feeding only, reduction roll 27 is driven with rotation (along the clockwise direction among Fig. 2) by feeding paper P.When having a plurality of paper P between feed rolls 23 and reduction roll 27, reduction roll 27 does not rotate, because the coefficient of friction between these paper is less than the coefficient of friction between reduction roll 27 and the paper P.Therefore, the following a piece of paper after the uppermost paper P that will be fed or more after paper P will can not advance in the downstream, thereby a plurality of paper can not be by the while feeding.

Guiding roller 25,26 can rotate freely, and is used for by driven roller 33 and driven voller 34 paper P being contacted at paper P transport process with transfer roller 23 and prevents to produce the transmission load.

The paper P of feeder 2 feedings arrives by guiding part 29 guiding the driven roller 33 that rotates by Motor Drive with by contacting the driven voller 34 that is driven in rotation with driven roller 33 pressure.Driven voller 34 passes through spring (not shown) axial support by the support 31 that is fixed on the main frame (not shown), and main frame constitutes the base member of printer 1.The paper P that arrives driven roller 33 is sent to the downstream by rotation driven voller 33 with predetermined spacing.

The downstream of driven roller 33 is furnished with ink jet print head (hereinafter being referred to as " record head ") 39 and the platen parts 41 relative with it.Record head 39 is arranged on the bottom of carrier 35, and is driven to move back and forth on main scanning direction by the drive motor (not shown), simultaneously by carrier guidance axis 37 guidings of extending on main scanning direction.And carrier 35 is equipped with the print cartridge (not shown) of multiple color, and these colors are separate, to supply to record head 39.

The platen parts 41 that are used for determining distance between paper P and the record head 39 are formed with rib 43 and recess 42 on the face relative with record head 39.Recess 42 is used to receive the China ink that is ejected in the zone of departing from paper P end, sends out the end that is used for print paper P thus and does not have the so-called no margin of margin to print.And recess 42 is provided with the black absorber (not shown) that absorbs received China ink, and described China ink is guided to the waste liq pallet (not shown) that is arranged on platen parts 41 bottoms from black absorber.

In the downstream of record head 39, the ejector that is provided with help roll 46 and forms by driven roller 44 and driven voller 45.A plurality of driven rollers 44 rotating driveshaft 44a axially on arrange.Driven voller 45 is arranged on by on the framework 47 that forms at the metal plate component that extends on the main scanning direction, and is driven in rotation by contacting with driven roller 44.Process is pushed so that launch accumulation device 13 by roller by the paper P of the record that record head 39 is carried out.And the help roll 46 that is arranged on the roller upstream side contacts with paper P from top, thereby so that be driven in rotation and keep between paper P and the record head 39 distance constant, is used to prevent that paper P from floating.

Printer 1 is configured to except paper P, can directly carry out ink mist recording with respect to the label surface such as the CD of compact disk.As shown in Figure 4, CD D (second recording medium) is sent to paper transport path under the state that places on the pallet-like T.Pallet T separates setting with printer 1, and inserts from the front side of printer 1, is supported by pallet guiding part 18 (describing below) simultaneously.

Shown in Fig. 3 and 4, pallet guiding part 18 is arranged on the downstream of driven roller 44 and driven voller 45 pivotly, so that take open mode by opening selectively towards the equipment front side, as shown in Figure 4, thereby support pallet T, perhaps take from closed condition, so that on vertical substantially direction, extend as shown in Figure 3 from open mode formation.

Figure 22 only is the perspective view of pallet guiding part 18 open modes, and Figure 23 only is the front view of pallet guiding part 18 closed conditions.Shown state obtains by removing its end cover.

In the accompanying drawings, the part of rodmeter 18d is exposed to the outside by being formed on pallet guiding part 18 lip-deep slit 18e.When pallet guiding part 18 moves to the closed position, be arranged on housing front surface 11a and go up so that enter slit 18e with the projection 11d of the relative (see figure 4) of slit 18e, and pivot rodmeter 18d.In Figure 23, reference number 18f represents pivot center.By pivot rotation sensor bar 18d, guiding sensor 18m connects, and can detect the closed condition of pallet guiding part 18 thus.By disconnecting the open mode that guiding sensor 18m detects pallet guiding part 18.

And rodmeter 18g is arranged on the sidepiece of guiding face 18a of pallet guiding part 18.When pallet T correctly was arranged on the guiding face 18a, the side of pallet T was around pivot center 18p pivot rodmeter 18g.Therefore tray sensor 18q is switched on " existence " that (ON) detects pallet thus.By disconnecting " not existing " that (OFF) tray sensor 18q detects pallet.And rodmeter 18g protects by the lid of covering protection in the above 18h.

As shown in figure 22, pallet keeps roller 18k to be pushed away from the top down with respect to the pallet T that is arranged on the guiding face 18a.As hereinafter described, under the release conditions of driven voller 45, the conveying capacity that acts on the conveyer of pallet T has reduced, and therefore, keeps roller 18k to be used for by promoting reducing of compensation conveying capacity.

And triangle telltale mark 18j aligns with same tag (not shown) on being arranged on pallet T, and pallet T is positioned the desired location on the pallet guiding part 18 thus.

By respectively pivot tray guiding part 18 and accumulation device 13, one of them that is used for the open position of each parts or closed position is selected as Fig. 1, shown in 3 and 4.That is, each parts vertically extend when they are in non-working condition.So that open towards the front side of equipment, they just are in user mode by each parts that pivot.When each parts were in non-working condition, pallet guiding part 18 was parallel to accumulation device and extends, and is positioned at the inboard of accumulation device 13 simultaneously.When each parts were in user mode, pallet guiding part 18 is horizontal-extending on accumulation device 13.Accumulation device 13 tilts a little, and the end, extend upward so that the paper P that prevents to launch out falls (also referring to Fig. 5 to 7).

As mentioned above, because printer 1 is provided with the pallet guiding part 18 that can optionally be in user mode or non-working condition by pivotal action in the downstream of ejector, therefore, needn't carry out the connection/disassembling section of pallet guiding part 18, and needn't manage guiding part 18 separately, become the user thus and grasp use easily.In addition, owing to just can be in user mode or non-working condition by pivotal action pallet guiding part 18 only, easier use therefore becomes.And, shown in Fig. 4 and 7, close a part of transfer path on the main scanning direction owing to be configured to be in the pallet guiding part 18 of open mode, and the pallet guiding part 18 under the closed condition can be from upwards withdrawal of transfer path, and therefore the standard recording medium (paper P) that is launched is deposited on the accumulation device 13 and can not be subjected to the interference of the pallet guiding part 18 under the closed condition.

And pallet guiding part 18 and accumulation device 13 are configured to similarly be pivoted, and are in non-working condition following time at each parts, and pallet guiding part 18 places the inboard of accumulation device 13, and the installing space of pallet guiding part 18 just can reach and minimize.

Below, be used for the release 50 of driven voller 45 with reference to figure 5 to 11 detailed descriptions from driven roller 44 releases.

Release 50 switches the second place that the primary importance of wherein driven voller 45 and driven roller 44 contacts and driven voller 45 wherein separate with driven roller 44.That is, use transfer or the free time of mill pinion that contacts with paper P point to prevent driven voller 45.But, when such mill pinion contacts with the label surface pressure of CD D, will exist by its projection and damage the stake that is right after the record data that below the CD label face, occur.Therefore, directly carry out on CD D in the ink mist recording, driven voller 45 separates with driven roller 44 by release 50, thereby driven voller 45 can not contact with the label surface of CD D.

Release 50 is configured to by with the pivot action cooperation of pallet guiding part 18 driven voller 45 being separated with the interconnected attaching parts of pallet guiding part 8 with driven roller 44.Shown in Fig. 8 and 9, attaching parts are made of connecting rod 51 and rocking bar 53.Rocking bar 53 comprises cylindrical portion 53a and the lever 53b that extends from

cylindrical portion

53a, 53c, and be configured to by cylindrical portion 53a being coupled to drive roller shaft 44a the clockwise direction of axle head in Fig. 9 and counterclockwise on pivotable.Connecting rod 51 is connected pallet guiding part 18 and rocking bar 53 by copulational protuberance 18c with axle 53e, and projection 18c is arranged on the position of the pivot 18b that departs from pallet guiding part 18, and axle 53e is arranged on the bar 53b.

Two guide pins 48,49 are arranged on two ends of framework 47 of axial support driven voller 45, so that go up outstandingly in vertically (side direction of printer 1 side), and have predetermined space between them.Guide pins 48,49 forms loosely and inserts guide hole 56a, and the state of 56b, guide

hole

56a, 56b are formed on from the extended guide plate 55 in framework 47 both

sides.Guide hole

56a, 56b are the grooves with step shape as shown in figure 11.By using

guide hole

56a, 56b guides guide pins 48,49 respectively, and framework 47 slides so that change the height and position of driven voller 45.

Here, framework 47 is configured to slide by rocking bar 53.Hole 53d forms the end of bar 53c, and guide pins 48 looselys are coupled among the 53d of hole.When axle 18b pivoted, the attaching parts that are made of connecting rod 51 and rocking bar 53 were operated at pallet guiding part 18, thus bar 53c provide external force to guide pins 48 so that in groove 56a, move, and framework 47 is slided.

Because

guide hole

56a, 56b is step-like, so framework 47 moves up gradually, slides into the front side (right side of accompanying drawing) of printer simultaneously, shown in the variation among Fig. 9 to 11.This be because carrier 35 appear under the state shown in Figure 9 framework 47 above (also can referring to Fig. 5).Framework 47 can not collide carrier 35, promptly avoids moving under the situation of carrier 35.

As shown in Figure 9, it shows the state that driven voller 45 is placed in primary importance, and Figure 11 illustrates the state that driven voller 45 is placed in the second place, and it is not by bar 53c but by bar 57 maintenances that guide pins 48 is configured to these states.In more detail, bar 57 forms V-type parts substantially, and is arranged to and can pivots around axle 58.Bar 57 is configured to pivot in the counter clockwise direction of Fig. 9 in the thrust that its end from an end 57a of axle 58 extensions applies extension spring 59.And, it engages guide pins 48 from the other end 57b that axle 58 extends, so that its inclined plane 57c goes up extruding guide pins 48 in the bottom of guide hole 56a direction (cardinal principle is in the direction left of accompanying drawing), thereby when being in primary importance, driven voller 45 driven voller 45 can be maintained primary importance (forming state of contact) with driven roller 44.Simultaneously, when driven voller 45 is in the second place (state that separates with driven roller 44), as shown in figure 11, its end face 57d the top ends direction of guide hole 56a (substantially accompanying drawing upward to) go up extruding guide pins 48, thereby driven voller 45 can be maintained the second place.

Followingly further explain in detail by mobile the providing that also comprises pallet guiding part 18 and accumulation device 13.Fig. 1 and 5 shows the situation that pallet guiding part 18 and accumulation device 13 are in closed condition respectively.In off position down, pallet guiding part 18 enters vertical extension state so that just in time extend vertically downward along the wall 11a (also referring to Fig. 4) that forms in the heart in housing 11 front sides.Accumulation device 13 also enters vertical extension state so that just in time along pallet guiding part 18.That is, enter closed condition, to the composed view requirement certain precision (positioning accuracy) of each parts in order to make pallet guiding part 18 and accumulation device 13.

Fig. 3 and 6 shows the front side that wherein only has accumulation device 13 to be pivoted to equipment and can pile up in the above state such as the paper P of common paper etc.In this state, the angle of accumulation device 13 enters the state by unshowned limiter control, thereby accumulation device 13 is static under acclivitous state as shown in the figure.Therefore, the paper P that is launched by driven roller 44 and driven voller 45 can correctly pile up and can not fall from accumulation device 13.

Thereby Fig. 4 and 7 shows the state that front side pallet T that wherein pallet guiding part 18 and accumulation device 13 be pivoted to equipment can insert from the front side of equipment.In this state, the angle of pallet guiding part 18 enters the state by unshowned limiter control, thereby in order directly to guide the arrival paper transport path with pallet T with the posture of cardinal principle level, guiding face 18b (referring to Fig. 4) forms horizontal plane.

Here, pallet guiding part 18 is entered the process of open mode shown in Figure 7 from closed condition shown in Figure 6, shown in changing among Fig. 9 to 11, pivot action according to pallet guiding part 18, at first, the inner rim of the hole 53d of bar 53c contacts with guide pins 48, thereby guide pins 48 is in guide hole 56a slides within.In the case, bar 57 motive force of resisting extension spring 59 is pivoted by as shown in figure 10 guide pins 48.

When guide pins 48 finally was arranged on the end face 57d of bar 57, the direction that imposes on the motive force of guide pins 48 by bar 57 was changed.Promptly, when guide pins 48 is positioned on the inclined plane 17c of bar 57, guide pins 48 is pulled to bottom (cardinal principle is in the direction left of accompanying drawing), and driven voller 45 is maintained at primary importance, but, when guide pins 48 is positioned on the end face 57d of bar 57, guide pins 48 by top ends (substantially accompanying drawing upward to) promote.Because guide pins 48 is at the inside of hole 53d freedom of entry state, so this top ends is promoted by bar 57, and driven voller 45 is in the second place.Like this, though bar 57 is only promoted by single extension spring 59 (push mechanism) in one direction, the direction that promotes guide pins 48 can change by inclined plane 57c and end face 57d.As shown in figure 11, the upper end of guide hole 56b is formed with horizontal part 56c so that keep guide pins 49, guide pins 49 is according to moving in guide hole 56b only moving of the upper end of guide hole 56b (second place of driven voller 45) guide pins 48, be tending towards moving down in described upper end guide pins 49, keep any parts of guide pins 49 the same with motive force with guide pins 48 because be used for by gravity.

Like this, the driven voller release is provided with dual stabilizer, is used for the pushing direction that is switched guide pins 48 by bar 57 according to the open angle of pallet guiding part 18 at the single extension spring 59 of catch bar 57 on single direction by using.Therefore, the driven voller release can enough simple structures close the lower cost realization.

Though omitted diagram, and its vertically at the opposite side of framework 47, be provided with corresponding to guide

pins

48,49

guide hole

56a, 56b, the element of bar 57 and extension spring 59.Therefore, on the two side ends of framework 47, guide pins is by the guide hole guiding, and maintains two positions by bar and extension spring.

Simultaneously, according to the above-mentioned pallet guiding part 18 that is used to change driven voller 45 height and positions, as mentioned above, pivoting angle (range of pivot, that is, positioning accuracy) is required certain precision.On the other hand,, must accurately guarantee the distance between driven voller 45 and the driven roller 44, thereby driven voller 45 can not contact in primary importance with driven roller 44 excess pressures, and driven voller 45 can not contact in the second place with the label surface of dish D for driven voller 45.That is, in order to coordinate pallet guiding part 18 and guide pins 48 (driven voller 45), it is that it is intrinsic that the high dimensional accuracy of connecting rod 51 and rocking bar 53 is required, and has increased cost thus.

Yet, according to present embodiment, attaching parts are used for two elements (pallet guiding part 18 and guide pins 48 (driven voller 45)) of the such higher positioning accuracy of interlocking needs, do not have the connected component rigidity to keep in the precalculated position as one of them guide pins 48 (driven voller 45) of these elements, but keep by extension spring 59 (push mechanism) is flexible.Therefore, connecting rod 51 and rocking bar 53 do not need high dimensional accuracy, can avoid increasing cost thus.In other words, each pallet guiding part 18 and driven voller 45 can be positioned and can not be subjected to the influence of connecting rod 51 or rocking bar 53 dimensional accuracies to keep high positioning accuracy.

In the present embodiment, in order to discharge driven voller 45 from driven roller 44, guide pins 48 and pallet guiding part 18 are by the attaching parts interlocking, thereby driven voller moves in vertical direction according to the opening/closing motion of pallet guiding part 18.But, also can be configured in driven voller 45 and the printer 1 mobile cooperation of another element and move in vertical direction.If the certain positioning accuracy of mobile needs of another element just may obtain above-mentioned effect.

Below, be used to regulate the platen clearance adjuster of gap between record head 39 and the platen parts 41 (hereinafter being referred to as " platen gap ") referring to figs 12 to 15 explanations.

Though the platen clearance adjuster is arranged on a side of carrier guidance axis 12 left-hand end, at first explain the formation of its right-hand member side.Shown in Figure 12 A and 12B, the guide channel 77 of Yan Shening is formed on framework 75 right flanks in vertical direction, this framework 75 is the U type on plan view, and axial support carrier guidance axis 12 (guide channel 77 also is formed on the left surface), and the axle head of carrier guidance axis 12 inserts by guide channel 77.The axle head of carrier guidance axis 12 is connected with dish 70, and the neighboring of dish is formed with four black out plates 103 with predetermined interval in a circumferential direction, is used for detecting the stability region by the sensor of being made up of optical transmitting set and optical receiver 105.

In Figure 12 B, draft helical spring 203 is the impellers that are used for stably keeping carrier guidance axis 12.Plate 201 is connected to the right flank of framework 75 so that constitute inside predetermined angular, is used for draft helical spring 203 between suspension plate 201 and the carrier guidance axis 12.Draft helical spring 203 is suspended on and is formed at the latch hook on the plate 201 and is formed between the groove on the carrier guidance axis 12, be used to promote carrier guidance axis 12 so that on three axial directions of the backward directions of vertically downward direction, printer and carrier guidance axis 12, produce component of force, so that reach following effect.

At first, though carrier guidance axis 12 is to insert by the guide channel 77 that extends in vertical direction, in the horizontal direction, between carrier guidance axis 12 and guide channel 77, formed gap to a certain degree.Therefore, draft helical spring 203 promote carrier guidance axis 12 to a side of guide channel 77 inside (according to the rear side of the printer of present embodiment) thereby so that the inside that carrier guidance axis 12 is stabilized in guide channel 77 can not produce between them crackling.

The second, though carrier guidance axis 12 support by the left and right side of framework 75 (having omitted the detailed icon explanation of support portion), also can produce in the axial direction crackling.Therefore, draft helical spring 203 promote carrier guidance axis 12 in the axial direction in case produce stable can not produce crackling.

The 3rd, a side of the left-hand end of carrier guidance axis 12 is provided with the gap adjustment cam 216 (describing below) shown in Figure 14 A.Because the platen gap is determined from top the contact with cam follower 211b (describing below) pressure by making gap adjustment cam 216, therefore draft helical spring 203 makes gap adjustment cam 216 contact with cam follower 211b pressure, thereby gap adjustment cam 216 can not break away from cam follower 211b and move up.That is, draft helical spring has been realized the function of stable gap adjustment cam 216, thereby the platen gap can change with meeting the requirements.

As mentioned above, carrier guidance axis 12 is made for and can stablizes on many directions with low cost by single draft helical spring 203, thus and saving space.And, side in the left-hand end of carrier guidance axis 12, pole spring 213 as shown in figure 13 makes gap adjustment cam 216 contact with cam follower 211b pressure, and carrier guidance axis 12 is pushed to guide channel 77 inside a side in case can not produce crackling, by using draft helical spring 203, can also realize being easier to control the advantage of the draft helical spring 203 of load than pole spring 213.

Shown in Figure 13 B, the platen clearance adjuster is arranged on the side of left-hand end of carrier guidance axis 12.In platen clearance adjuster according to present embodiment, power is from being transferred to the guidance axis gear 215 on the left-hand end that is connected to carrier guidance axis 12 as the drive motor 51 of power source special by first gear, 205, the second gears 207 and the 3rd gear 209 (gear of being made up of the two-stage gear).The platen gap changes by rotation guidance axis gear 215.And all these parts are connected on the left surface of framework 75 (not shown).

To at length explain guidance axis gear 215.Guidance axis gear 215 is included on the part of its neighboring and tooth portion the 3rd gears engaged and is not provided with the anodontia portion of tooth portion, on its directly upwards outstanding projection 218 is formed on border between tooth portion and the anodontia portion.Simultaneously, gap adjustment cam 216 is formed on the card of guidance axis gear 215, and its cam surface is formed with in its directly upwards outstanding projection 217.

And, parallel adjusting lining 211 be formed on guidance axis gear 215 near.Parallel adjusting lining 211 is used to regulate the collimation of carrier guidance axis 12, and is connected on each of left and right side of framework 75.Parallel adjusting lining 211 is formed with cam follower 211b, and the platen gap is determined from top the contact with cam follower 211b pressure by making gap adjustment cam 216.That is, being shaped as by the distance of this shape apart from the axis of carrier guidance axis 12 that the cam surface of gap adjustment cam 216 forms is changed, and wherein carrier guidance axis 12 is a rotating shaft.Therefore, shown in Figure 14 A to 14D, the distance between carrier guidance axis 12 and the cam follower 211b is to rotate according to the pivot of guidance axis gear 215 to change, and changes the platen gap thus.And parallel adjusting lining 211 is made for and can pivots around the hole 211a that not shown axle inserts wherein.By the parallel adjusting lining 211 that pivots, change the platen gap equally.Therefore, by the parallel adjusting lining 211 in the pivot left and right sides, the collimation that just can regulate carrier guidance axis 12.

Hereinafter, thereby explanation is used to limit the limiter that gap adjustment cam 216 range of pivot gap adjustment cams 216 can pivot between the stability region, and the platen gap can be maximized and minimize in described stability region, equally referring to Figure 15.

In Figure 15, abscissa direction indication rotatable phase position.Thick line 83 expressions in the case, show displacement upwards increasing upward at coordinate corresponding to the displacement in the platen gap of drive motor 51 rotations.Shown in figure thick line 83,, can select four levels in platen gap according to present embodiment.The horizontal part of thick line 83 represent respectively 4 levels in platen

gap stability region

95,96,97 and 98 (, Typ ,+, ++).Stability region 96 by " Typ " expression is the platen gaps that are used for corresponding to having the standard thickness paper.By "-" even the stability region 95 of expression is the platen gap that is used for absorbing the thick paper that Mo Shiye can not be out of shape.By the stability region 97 of "+" expression is the platen gap of thin paper easily deformable when being used to absorb China ink.Stability region 98 by " ++ " expression is the platen gaps that produce the thin paper of huge distortion when being used to absorb China ink.Interval between each

stability region

95,96,97 and 98 is formed with the transitional region 99,100,101 that switches to each stability region.

In order to keep the platen clearance constant in respect to the recording process of recording medium, the platen gap need be seated in any one

stability region

95,96,97 and 98 and needn't be seated in any one transition region 99,100,101.Therefore, shown in Figure 12 B, four light barriers 103 (only having shown two light barriers 103 in the figure) mutually are formed on the neighboring with the coaxial dish 70 of guidance axis gear 215 at certain intervals.Shown in Figure 12 A, optical pressure paper gap sensor 105 be arranged on the dish 70 near.Platen gap sensor 105 comprises optical transmitting set and optical receiver, thereby detects the existence of light barrier or do not exist according to the fact of sending from optical transmitting set that is not only not received by optical receiver.

The position of four light barriers 103 is corresponding to

stability region

95,96,97,98 on dish 70 neighborings.Any one stops the light time at platen gap sensor 105 places in four light barriers, and the judgment means (not shown) judges that the platen gap enters any stability region.And because four light barriers 103 sequentially stop light continuously, judgment means can judge which light barrier has stopped light, determines that thus the platen gap enters one of them stability region.

In Figure 15, the thick line 83 relevant positions that are blocked of light and the progression of representing the platen gap in the thick line 107 expression platen gap sensors 105.The higher level of thick line 83 represents " light-blocking state ", and its subordinate represents " light transmitting state ".From above-mentioned correlation ratio, obviously the length of the length of each light barrier 103 and each stability region width does not match.Length dimension on dish 70 circumferencial directions is confirmed as mating the core (except the end of contiguous transition region) of each stability region.Therefore, can prevent that platen gap sensor 105 is owing to reasons such as tolerance are defined as the stability region with transition region mistakenly.

The current state in platen gap can not only be determined with platen gap sensor 105.Therefore, in the present embodiment, a limiter is set, is used to limit the range of pivot of gap adjustment cam 216, so that gap adjustment cam 216 can pivot between minimum and maximum stability region, platen gap.More particularly, when being minimized shown in Figure 14 A in the platen gap, projection 217 can contact with cam follower 211b, thereby further prevents gap adjustment cam 216 (guidance axis gear 215) pivot (on the counter clockwise direction of accompanying drawing).And in the platen gap as Figure 14 D when being maximized, projection 218 can form with the gear 209b that forms the 3rd gear 209 and contact, so that prevent further pivot (on the clockwise direction of accompanying drawing) of gap adjustment cam 216 (side shaft gear 215).As mentioned above, the range of pivot of gap adjustment cam 216 is limited, thereby gap adjustment cam 216 only pivots between the platen gap is by minimum and maximized stability region.

Represent the confined position of pivoting action of gap adjustment cam 216 as mentioned above at " adjoining position " shown in the both sides of Figure 15.In reset operation, drive motor 51 rotates making on projection 217 and the direction that cam follower 211b contacts.Here, even under the situation that the state that is applied to drive motor 51 preset times platen gap sensor 105 during the cycle at drive current does not also change, determine that projection 217 contacts with cam follower 211b formation shown in Figure 14 A, that is, determine that current platen gap is minimum platen gap.Below, in order to seek the home position of carrier 10, the platen gap becomes maximization, monitors the detection signal of platen gap sensor 105 simultaneously, and is back to minimum platen gap once more so that form the printing holding state.

As mentioned above, the current state in platen gap can only be judged with platen gap sensor 105, realize the reduction of cost thus.

Below, explain constituting the CDR guiding detector of the object of the invention that the recording equipment of feeding operation is carried out on optimization ground under the state of CDR pallet detector and platen clearance detector.

Below, will explain based on guiding sensor 18m, the optimum feeding operation of first recording medium of tray sensor 18q and paper sensor 4 (the single page cut paper is opened P) and second recording medium (being provided with the pallet T of CD D), the control of operation is operated and launched to record.

Figure 16 explains each condition that does not begin (before printing) and begun (printing) operating in conjunction with record, with for guiding

sensor

18m, 16 kinds of modes of the situation that the corresponding two states of tray sensor 18q and paper sensor 4 is divided are relevant, the form of the content that recording equipment was carried out when hand switch 5 activated.

Figure 17 is corresponding to the flow chart of explaining Figure 16 operation.Nos.1 among Figure 17,2,5,6,7,8,10 and 15 corresponding to the corresponding label among Figure 16.

Figure 18 to 20 explains to have described to work as guiding sensor 18m, the corresponding two states of tray sensor 18q and paper sensor 4, the record data that wherein are used for first recording medium (Figure 18 be used for the data that cut paper is opened) are received and wherein are used for the received situation of record data (data that are used for the CD-R of Figure 19 and Figure 20) of second recording medium, during the difference dividing condition, the form of the operation of the content of operation that the recording equipment relevant with 16 kinds of modes of these situations carried out.

Controller 7 is configured to carry out respectively the operation corresponding to 16 kinds of modes of the corresponding state of describing among 16 kinds of modes of the corresponding state of describing among Figure 16 and Figure 18 to 20.More particularly, it is constructed as follows:

(1) to be configured to the detection signal of guiding sensor 18m when the preceding actuate manual switch 5 of beginning executive logging operation (Nos.5 to 8 of Figure 16) time be under the situation of " open mode " to controller 7, forbids the feeding operation of paper P.Controller 7 is configured to forbid by apparatus for sheet feeder of being made up of driven roller 33 and driven voller 34 2 or conveyer the feeding operation of paper P, and irrelevant with the state of tray sensor 18q and paper sensor 4 detections.

Thus, therefore paper P can, can not prevent to produce the obstructing problem that causes such as paperboard owing to paper P bump pallet guiding part 18 by actuate manual switch 5 by evenly feeding.

(2) controller 7 be configured to when beginning executive logging operation (No.7 of Figure 16) before during actuate manual switch 5 detection signal of guiding sensor 18m be " open mode ", the detection signal of tray sensor 18q is that the detection signal of " existence " and paper sensor 4 is under the situation of " not existing ", forbid the feeding operation of paper P, but operation is so that launch the equipment body outside by ejector with pallet T.

Thus, when pallet T is set on the pallet guiding part 18, when actuate manual switch 5, automatically launch pallet T, therefore, can save time and work that the user takes out the pallet T on the pallet guiding part, further form the user thus and grasp use easily.

(3) controller 7 is configured to be under the situation of " open mode " (Nos.5 to 8 of Figure 18), to forbid the feeding operation of the first recording medium P at the detection signal as guiding sensor 18m when PC etc. receives the record data that are used for cut paper.Here, controller 7 is configured to send the information of pallet guiding part 18 being changed into " closed condition ", and can operate the record operation of execution with respect to paper P when the detection signal of guiding sensor 18m is " closed condition " (Nos.5 to 8 of Figure 18).

Thus, sending the information of pallet guiding part 18 being changed into " closed condition ", and the user recovers reset condition when according to this information pallet guiding part 18 being changed into " closed condition ", therefore, in fact paper P executive logging is operated.Therefore, can continue the executive logging operation and can not damage the step of preparing to carry out the record operation of before receiving the cut paper record data, having finished.In Figure 18, " SN " information is the information that is transferred to recording equipment when printing when carrying out, and its type according to paper, size and thickness etc. are divided and numbered.

(4) controller 7 is configured to when receiving the record data that are used for cut paper under the pattern of above-mentioned (3), the detection signal of guiding sensor 18m is " open mode ", the detection signal of tray sensor 18q is that the detection signal of " existence " and paper sensor 4 is under the situation of " not existing ", forbid the feeding operation of paper P, and pallet T is launched the equipment body outside by ejector.

Thus, except the advantage of above-mentioned pattern (3), under pallet T when receiving the record data that are used for cut paper is set to situation on the pallet guiding part 18, automatically launch pallet T, therefore, can save time and work that the user takes out the pallet T on the pallet guiding part, further form the user thus and grasp use easily.

(5) to be configured to the detection signal at guiding sensor 18m when receiving the record data that are used for CD-R be that the detection signal of " closed condition " and tray sensor 18q is to switch under the situation of " not existing " with the CD-R record data to carry out record operation (Nos.9 of Figure 19 and 10) for paper P to controller 7.

The detection signal that guiding pallet guiding part 18 is in " closed condition " and tray sensor 18q when recording equipment receives the record data that are used for CD-R is that the situation of " not existing " is forgotten carelessly corresponding to the user usually pallet T is set to situation on the pallet guiding part of opening 18.That is, when the user forgets setting pallet T, anything can not take place, and this state continuance.CD such as compact disk is exemplified as second destination media.The price of CD descends recently, and still, the user still can not carry out the test printing the same with common paper easily.

Thus, in the case, controller 7 is configured to switch to the record operation of carrying out paper P with the record data of CD-R.Therefore, can prevent that the situation that anything does not take place from continuing, the user can notice this situation thus.And the print data that is used for CD can be used in the record on the common paper, uses print image as the test printing result thus.

(6) detection signal of guiding sensor 18m is " open mode " when receiving the CD-R record data, the detection signal of paper sensor 4 is under the situation of " existence ", the information of " closed condition " is changed into pallet guiding part 18 in transmission, when the detection signal of guiding sensor 18m was changed into " closed condition ", controller 7 switched to the record operation (Nos.14 to 16 of Figure 20) of carrying out paper P with the record data of CD-R.

Controller 7 is configured to send the information that pallet guiding part 18 is changed into " closed condition " and gives the user, and directly carries out the record operation of paper P when the user changes into " closed condition " according to this information with pallet guiding part 18 with the record data of CD-R.Therefore, can prevent that the situation that anything does not take place from continuing, the user can notice this situation thus.And the print data of CD can be used in the record on common paper, uses print image as the test printing result thus.

(7) detection signal of guiding sensor 18m is " open mode " when receiving the record data of CD-R, the detection signal of tray sensor 18q is that the detection signal of " not existing " and paper sensor 4 is under the situation of " not existing ", sends to make the user that pallet T is set to information on the pallet guiding part 18.When the detection signal at tray sensor 18q becomes " existence ", when actuate manual switch 5, use the record data of CD-R to CD-R executive logging (No.13 of Figure 19).

The user is according to operation spended time and the work of this information setting pallet T, because pallet T separates setting with pallet guiding part 18, the time of setting pallet T requirement thus is changeable.Therefore, can preset separately if set the time of pallet T, will be that inconstant practical situation is opposite with the time of setting pallet T.

Controller 7 be configured to according to the user not only be set to pallet P on the pallet guiding part 18 and also after this condition of actuate manual switch 5 with the record data of CD-R to the CD-R executive logging.Therefore, will be inconstant practical situation coupling with the time of setting pallet T, further form the user thus and grasp use easily.

(8) detection signal of guiding sensor 18m is " open mode " when receiving the record data of CD-R, the detection signal of 11 tray sensor 18q is " existence ", the detection signal of paper sensor 4 is " not existing ", and equipment is under the situation of the holding state of wherein carrying out timer clear operation etc., controller 7 is configured to launch pallet T and finish beamhouse operation by ejector, after this, send and to make the user that pallet T is set to information on the pallet guiding part 18.When the detection signal at tray sensor 18q is changed into " existence ", when actuate manual switch 5, use the record data of CD-R to CD-R executive logging (No.15 of Figure 20).

This equipment has such structure, wherein can not realize the beamhouse operation of timer zero clearing etc. under pallet T is set to state on the pallet guiding part 18.

According to the present invention, when equipment was in the holding state of execution such as the beamhouse operation of timer zero clearing, controller 7 launched pallet T by ejector, and finished beamhouse operation, after this, sent and to make the user that pallet T is set to information on the pallet guiding part 18.When the detection signal at tray sensor 18q is changed into " existence ", when actuate manual switch 5, use the record data of CD-R to the CD-R executive logging.Therefore, to carrying out the structure that can further realize grasping easily use such as the operation note equipment of the recovery record head of timer zero clearing etc. with the user.

(9) when the detection signal of the recording process sensor 18 that is used for paper P is changed into " open mode ", the transfer operation of conveyer suspends (Nos.6 of Figure 18 and 8).

According to the present invention, when being used for recording process user such as the first recording medium P of cut paper etc. and opening pallet guiding part 18, controller 7 is configured to stop immediately the transfer operation of the recording medium P that being carried out by conveyer.Therefore, can prevent to produce serious paper jam phenomenon.

Figure 21 shows the concrete size and corresponding use of four levels in above-mentioned platen gap.

When the pallet guiding part is opened, unconditionally be the state (the maximal clearance amount for example, is 4.2mm) that uses the CD-R pallet preferably with the platen space change by operation platen gap adjusting mechanism.Utilize this structure, though platen gap adjusting mechanism operation record data show the platen gap should be used for plain paper time the maximum platen of mandatory generation gap.Therefore, even when pallet undesirably is set on the pallet guiding part, there is not the consideration that damages record head yet.

Below, explain by determining that according to the center of optical disc recording medium of the present invention equipment and center determine that method determines the example of the detailed process of the center of CD in the recording equipment.

Usually, with based on disc holder scanning is compared, based on the direct scanning of CD is determined that the center of CD can be more accurate.But, on the label surface at CD in advance under the situation of printable character or figure, perhaps under CD has erose situation except circle, the center that CD is determined is tending towards departing from significantly its actual center, determines that thus precision is lower than the definite precision based on disc holder scanning.

Therefore,, calculate based on to the cd centre position of the direct scanning of CD with based on center, and calculate distance between the center of cd centre position and CD installation portion the CD installation portion of disc holder scanning according to present embodiment.Distance between the center is during less than the value of predetermined reference value, based on to directly scanning and the cd centre position of calculating is confirmed as the center of CD of CD.On the other hand, the distance between the center is when being equal to or greater than the value of predetermined reference value, is confirmed as the center of CD based on the center of the CD installation portion that disc holder scanning is calculated.

As mentioned above, by adopting the cd centre position of calculating selectively, can obtain more accurate and high-precision cd centre position by dual mode.

Figure 24 shows the example of the program of scanning CD and CD holder substantially.

In this embodiment, as shown in figure 25, used the CD holder T that is furnished with two groups of (four) position marks, for example under the state that CD D is installed on the CD dress 111a of portion, realized scanning by optical pickocff.

At first, the path (1) that comprises the subscan line is scanned so that detect the Y coordinate position TY1 of the 3rd position mark 111Y1.

Then, the path (2) that comprises main scanning line is scanned so that detect the X coordinate position TX1 of primary importance mark 111 * 1 and second place mark 111X2, TX2 respectively.

Further, the path (3) that comprises the subscan line is scanned so that detect the Y coordinate position MY1 of a side end that is arranged on the CD on the scan line, MY2 and end side, and the Y coordinate position TY2 of the 4th position mark 111Y2 respectively.

At last, the path (4) that comprises main scanning line is scanned so that detect the X coordinate position MX1 of a side end that is arranged on the CD on the scan line, MX2 respectively.

And above-mentioned scanning sequency is an example, and scanning sequency is arbitrarily, as long as can detect four parts of CD and four position marks of CD holder.In addition, there is the carrier of optical pickocff 41 to realize by drive installation on main scanning direction by the scanning of optical pickocff 41 along main scanning line, stop at corresponding to the position in the X coordinate range of the width of the 3rd position mark 111Y1 and the 4th position mark 111Y2 by the carrier that optical pickocff 41 will be installed on main scanning direction, and on sub scanning direction, promptly, conveyer by PRN device transmits on the direction of recording medium, and moving CD carriage T realizes by the scanning of optical pickocff 41 along the subscan line.

Detect the coordinate time of the position mark of four parts of CD and four optical disc trays at optical pickocff, based on the center of the coordinate Calculation CD of four parts of CD, based on the center of the coordinate Calculation CD installation portion 111a of the position mark of four optical disc trays.

At first, from the side end that is arranged on CD D on the main scanning line and the X coordinate position MX1 of end side, MX2 calculates the X coordinate position MX=(MX1+MX2)/2 of CD D center, from the side end that is arranged on CD D on the subscan line and the Y coordinate position MY1 of end side, MY2 calculates the Y coordinate position MY=(MY1+MY2)/2 of CD D center, thus based on the center (MX that the direct scanning of CD is calculated CD, MY)=((MX1+MX2)/2, (MY1+MY2)/2).

Simultaneously, from the primary importance mark 111X1 that is arranged on the CD holder on the subscan line and the X coordinate position TX1 of second place mark 111X2, TX2 calculates the X coordinate position TX=(TX1+TX2)/2 of the center of CD installation portion 111a, from the 3rd position mark 111Y1 that is arranged on the CD holder on the subscan line and the Y coordinate position TY1 of the 4th position mark 111Y2, TY2 calculates the Y coordinate position TY=(TY1+TY2)/2 of the center of CD installation portion 111a, thus based on the center (TX that the scanning of CD holder T is calculated CD installation portion 111a, TY)=((TX1+TX2)/2, (TY1+TY2)/2).

And (MX, MY) and based on the center to CD holder T scanning calculating CD installation portion 111a (TX, order TY) is arbitrarily based on CD directly being scanned the center of calculating CD D.

Based on CD directly being scanned the center (MX that calculates CD D, MY) with based on the center (TX that CD holder T scanning is calculated CD installation portion 111a, TY) after, by following equation calculate between two central parts apart from d:d=[(MX-TX) ²+ (MY-TY) ²] ^1/2

Between the center apart from d less than reference value dref (d＜d _Ref) time, with distance of the calculating between the center and predetermined reference value d _RefCompare, (MX MY) is confirmed as the center of CD, and is equal to or greater than reference value dref (d 〉=d apart from d between the center in the center of the CD D that calculates based on CD is directly scanned _Ref) time, based on to CD holder T scanning and (TX TY) is confirmed as the center of CD in the center of the CD installation portion 111a that calculates.

Though predetermined dref value is arbitrarily, when CD was circular CD, this value can be to equal and value based on the corresponding distance of worst error to direct scanning of CD and between the cd centre position of calculating and the CD practical center position.Because the calculating between the center apart from d be equal to or greater than this apart from the time, just be likely that CD on the CD installation portion 111a that is installed in optical disc tray T is that wherein character and figure etc. are printed on CD on its label surface in advance, or have the erose CD except circle.That is, can predict based on (TX is TY) than (MX MY) approaches the practical center position of CD more based on the cd centre position that CD is directly scanned to the center of the CD installation portion 111a of CD holder T scanning.

The occurrence of predetermined reference value dref can be by the value in 0.4 millimeter to 0.5 millimeter scope, as 0.5 millimeter, and 3/180 inch compositions such as (approximating 0.4 millimeter).

Finish above-mentioned control operation by the controller shown in Fig. 57.

Figure 26 is the flow chart of the distortion example of above-mentioned control method.More particularly, the center of the center of the CD installation site of pallet T and CD D depart from and reference value between relatively separately main scanning direction and sub scanning direction are carried out.

At first, certain set positions of inserting pallet T is 0, and the paper feed direction is defined as forward, and rightabout is defined as negative sense.Below, the mark TY1 of detection pallet T on sub scanning direction, TY2.Y coordinate position TCY (step S1) from the center of circle of this position calculation pallet T.Simultaneously, on main scanning direction, detect the mark TX1 of pallet T, TX2.Calculate the X coordinate position TCX (step S2) in the center of circle of pallet T.Below, scanning CD D is so that provide coordinate position MY1, MY2 on sub scanning direction.Centre coordinate position MCY (step S3) from this position calculation CD D.Simultaneously, on main scanning direction, scan CD D so that coordinate position MX1, MX2 are provided.Calculate the centre coordinate position MCX (step S4) of CD D.

From value MY1, the diameter that MY2 determine to set medium whether be 12 centimetres or 8 centimetres (CD mark=1) or other value (CD mark=2) (step S5, S6).Have (that is, CD mark=2) under the erose situation at CD, the centre coordinate of printing (PX, PY) use the pallet center (TCX, TCY) (step S7, S8).

Be under 1 the situation at CD mark (flag), when the deviation value on main scanning direction during greater than reference value A, print center PX uses the center TCX of pallet, and as deviation value during less than reference value A, the center MCX (step S9 to S11) of use CD.Simultaneously, be labeled as at CD under 1 the situation, when the deviation value on the paper feed direction greater than certain during apart from B, print center PY just uses the center TCY of pallet, during less than distance B, just uses the center MCY (step S12 to S14) of CD at deviation value.

In the present embodiment, in order to determine the center of optical record medium, detect the side end of CD D and the X coordinate position MX1 of end side on the line that passes CD D center line by optical pickocff, MX2, X coordinate position from the value calculating central position that detected calculates Y coordinate position MY equally.But described line can not be the line that passes CD D center line.

In the present embodiment, 111X2,111Y1, the disc holder T of 111Y2 have been used to comprise position mark 111X1.But the mark of arbitrary patterns is employed as position mark, the layout as long as they are associated with the center of CD installation portion, and can detect by optical scanner.

For example, the X coordinate (main scanning direction) of expression CD installation portion center and two position marks of Y coordinate (sub scanning direction) are distributed on main scanning line and the subscan line discriminably.In the case, pass the main scanning line and the subscan line of two position marks, can determine the center of CD installation portion immediately by tracking.

And, pattern as position mark, can adopt the position mark of arbitrary patterns, comprise: franking on the precalculated position of CD holder, comprise the mark of the little chip part that is anchored on the precalculated position on the CD holder, and comprise mark of the opening on the precalculated position that is formed on the CD holder etc.
