Description
Technical field
The present invention relates to a kind of image recording structure that is used on the sheet material transport path, recording an image in the feeding sheets on the sheet material.
Background technology
In the electrophotographic image pen recorder, sheet material is fed to the image recording parts from the feeding sheet materials dish, be formed on the sheet material at this image.Then sheet material is outputed to the sheet material delivery cartridge.Sheet material can block its passage on the sheet material transport path.Sheet material blocks especially and may appear in the image recording parts.This is because sheet material experience in the image recording parts in the process of various operations and is easy to curl, such as developer-image transfer printing process of being carried out by transfer device or by the photographic fixing operation of fixing device execution.
Sheet material blocks and may appear at equally in the reverse transfer path, in be shaped at dual-side image (two sides at sheet material forms image), will have the sheet material upset that is formed on the image on first and transfer back to the image recording parts on the reverse transfer path.This is because dual-side image is shaped and relates to the sheet material of many branches of passing the sheet material transmission path.
When sheet material blocked, image recording structure suspended the figure forming process till all sheet materials of removing on the sheet material transport path.JP H09-134050A discloses by the sidewall etc. of pulling out the image recording parts forward and opening these parts from image recording structure exposing the sheet material transport path, thereby removes the sheet material that is stuck in the image recording parts.
Yet, the aforementioned structure of one type of prior art syringe, though with the image recording parts pull out and open sidewall also only exposed the sheet material transport path that is arranged in the image recording parts than small part.Therefore, this structure still makes the user than the difficult sheet material that blocks of removing.Especially, the image recording structure recently of high functionality has complicated structure, make its be difficult to be provided for removing the sheet material that blocks than large space.
On the sheet material transport path, exist in the consecutive image shaping of many sheet materials, iff can utilize the sheet material transport path that exposed than small part, then the user is in order to check whether all sheet materials have all been removed sidewall or the similar different piece that just must open the image recording parts from the sheet material transport path.
In order to address the above problem, the image recording structure that is proposed comprises movable first module and movable Unit second.In first module, disposed first path as the part of sheet material transport path.First module can move to the place ahead of this device along first direction, to pull out from this device.When first module was pulled out from this device, Unit second can move along the second direction perpendicular to first direction, to pull out from first module.In Unit second, disposed second path as another part of sheet material transport path.
Since the existing space that is used for removing printed sheets also can be used as with unit 2 from the unit 1 space of pulling out, so the device that this proposed does not need to be used for the private space of Unit second along second direction from first module.Equally, the device that is proposed allows Unit second to pull out from first module and separate with first module, therefore make first and second paths can expose more multiaspect than in conventional apparatus and amass that described Unit first and second integral body in described conventional apparatus is merged into a unit.
In addition, in first module, fixing device is located along first path.This fixing device has: the warm-up mill that is used to be melted in the toner image that forms on the sheet material; With the pressure roll that is pressed against on the warm-up mill, this pressure roll is used to apply pressure to sheet material.When first module is pulled out, exposed the outer matrix section of fixing device from device.Described fixing device also has the sheet material that contacts the location with the corresponding outer surface of warm-up mill and pressure roll and removes device.
In addition, whole fixing device is covered by shell, and all as described above assemblies firmly are positioned below this shell.Provide shell to be because compare with the assembly of other device, all assemblies of fixing device are warmmer owing to the heating of warm-up mill.Described shell has prevented the overheated of other device, and also the circumferential surface with warm-up mill maintains steady temperature.
Yet the structure of the device that is proposed makes sheet material block to such an extent that the user is difficult to the sheet material that is stuck in the fixing device is removed, and owing to the heating of fixing device makes it to become difficult more.In having the image recording structure recently of high speed printing performance, can not be once the rotation that delivery roll takes place to stop soon, but the sheet material that blocks still transmits till delivery roll stops forward.Therefore, the sheet material that blocks is entangled between warm-up mill and the pressure roll sometimes, even sheet material also is like this when blocking the position that occurs in beyond the fixing device.Therefore, importantly make and to remove the sheet material that is stuck in the fixing device more simply.
A possible solution is must contact the contact member of placing such as sheet material removes device with the outer surface of warm-up mill and remove from described outer surface, to expose this outer surface.Yet the image recording structure that is proposed requires two steps with mobile contact member: at first, mobile vacating space into contact member is pulled out in Unit second from first module; And only mobile then contact member.
Feature of the present invention provides a kind of image recording structure that helps removing the sheet material in the fixing device that is stuck in first module.

Sheet material blocks relatively and more easily occurs in first branch 24, second branch 25 and the 3rd branch 26 that the part in path 12 sets gradually.Plate 6 pivots rotate to the open site to expose all branches 24 to 26 and to be provided to the inlet of branch 24 to 26.This helps at the sheet material that takes place to remove when sheet material blocks in path 12 and 13.
In unit 2, be provided with the second portion of fixing device 37.In second portion, be provided with and remove the member of device 37AA as sheet material as the example of the contact element in the claim.Second portion can separate from first when pull out from unit 1 unit 2.Sheet material removes device 37AA and contacts the location with roller 37A so that remove through the sheet material between roller 37A and the 37B from the outer surface of roller 37A.
With reference to figure 5, when Pullout unit 2 from unit 1, the part that sheet material removes device 37AA and shell 50 is removed from the first of fixing device 37, and described shell has prevented the heat radiation of roller 37A etc.
Expose the outer surface of roller 37A like this and sticked to the sheet material that blocks on the described outer surface.Sheet material is removed device 37AA to be removed to be beneficial to effectively from the outer surface of roller 37A and exposes and remove the sheet material block thus.This is especially because be stuck in the outer surface that sheet material in the device 37 sticks to roller 37A usually.Therefore, the structure of the present embodiment helps removing the sheet material that blocks from fixing device 37.
In the present embodiment, sheet material removes in the second portion that device 37AA is positioned fixing device 37.Yet contact element includes but are not limited to: sheet material and removes device 37AA.As contact element, thus provided be arranged on any element in the second portion to satisfy can be when second portion be attached to first this element contact with the outer surface of warm-up mill 37A and when second portion leaves first this element do not contact and expose described outer surface with described outer surface.
Contact element also includes but are not limited to, the element that contacts with the outer surface of roller 37A.Be arranged on any element in the second portion, also will satisfy the outer surface contact of described element and pressure roll 37B when second portion is attached to first and do not contact and expose described outer surface when second portion described element when first separates with described outer surface.An example of this element is that sheet material removes device 37BB, and is as shown in Figure 6, and the outer surface of itself and roller 37B is arranged in contact.
Shown that in Fig. 8 A and 8B sheet material removes the structure of device 37AA.Fig. 8 A is the view that removes device 37AA from the sheet material that the direction of the arrow P of Fig. 5 is seen.Fig. 8 B is the view that removes device 37AA from the sheet material shown in the direction of the arrow Q shown in Fig. 5.In Fig. 8 A, unit 2 is not shown for simplification.
With reference to figure 8A and 8B, sheet material removes device 37AA and is supported by axle 60.Axle 60 is corresponding to the support member in the claim.Separating mechanism 70 is installed in the end of axle 60.Mechanism 70 comprises bar 71 and electromagnet 72.Mechanism 70 makes sheet material remove device 37AA and can move at contact position A with between away from position B.At contact position A, when unit 2 inserted in the unit 1 fully, sheet material removed device 37AA and contacts with the outer surface of warm-up mill 37A.Away from position B, when pulled out from unit 1 unit 2, sheet material removed device 37AA and does not leave and contact with the outer surface of roller 37A.
For the sensor 80 of feeler is installed on the unit 1.Sensor 80 detections contact with unit 2, thereby determining unit 2 is inserted in the unit 1 fully.Also for the sensor 81 of feeler is installed on the handle 21, described handle is arranged on the unit 2.Sensor 81 detects the user and is held on the handle 21.Sensor 81 is corresponding to the pick-up unit in the claim.As sensor 80 and 81, also selectively use non-contact sensor.
Based on the testing result of sensor 80 and 81, parts 90 determine whether that unit 2 will pull out from unit 1.Especially specifically, unit 2 is crooked to insert unit 1 and sensor 81 when detecting the user and holding handle 21 when sensor 80 detects, and parts 90 determine that users will pull out unit 2 from unit 1.This is to hold handle 21 expression unit 2 when inserting in the unit 1 fully because of unit 2 will be drawn out.
Fig. 9 shows that mobile sheet material removes the process flow diagram of the process of device 37AA.When the testing result based on sensor 80 and 81, when determining unit 2 maybe will have been pulled out from unit 1, parts 90 were opened electromagnet 72 (step S1).Therefore sheet metal 71B is adsorbed onto on the electromagnet 72, thus bar 71 rotations with sheet material is removed device 37AA from the contact position A shown in Figure 10 A move to shown in Figure 10 B away from position B.
For following reason, even Figure 37 AA is configured to still move on to position B when determining unit 2 will be pulled out from unit 1.The detection that is held on the handle 21 is pulled out from unit 1 prior to determining unit 2.Therefore, always can positively detect unit 2 will pull out from unit 1, and pull out from unit 1 slightly when inserting unit 1 again then when unit 2 sometimes, be difficult to determining unit 2 and pull out from unit 1.As another distortion of said structure, can only use sensor 80 and do not use sensor 81.
Then, parts 90 determine whether that unit 2 has inserted (step S2) in the unit 1 fully, and wait for and inserting fully in the unit 1 up to unit 2.Especially specifically, insert in the unit 1 and sensor 81 when not detecting the user and contacting handle 21 when sensor 80 detects unit 2, parts 90 determining units 2 are inserted in the unit 1 fully.
When determining unit 2 in step S2 had been inserted in the unit 1 fully, parts 90 were closed electromagnet 71 (step S3) and are stopped this program.Therefore, sheet metal 71B moves along the direction of leaving electromagnet 72 by the thrust of spring, and bar 71 rotations move to the position A shown in Figure 10 A sheet material is removed device 37AA from the position B shown in Figure 10 B thus.
Sheet material removes device 37AA and 2 inserts back, unit 1 fully and move on to position A from position B in the unit.This has prevented because outer surface that cause and A roller 37 collides the potential damage that the sheet material that causes removes device 37AA in the unit 1 by unit 2 is inserted when sheet material removes device 37AA and is in position A.
Sheet material being removed device 37AA when pull out from unit 1 unit 2 moves on to position B and is in position B to guarantee that sheet material removes device 37AA when unit 2 inserts unit 1 fully.This has simplified sheet material has been removed the time limit control that device 37AA moves on to position B.
Should be noted in the discussion above that separating mechanism 70, the tripping device during sensor 80 and control section 90 common respective rights require.
In the present embodiment, sheet material removes device 37AA will pull out time shift to position B in unit 2 from unit 1, and unit 2 be in 1 outside, unit during remain on position B.Yet sheet material removes the location of device 37AA including, but not limited to foregoing.For sheet material remove device 37AA only necessary be when unit 2 inserts unit 1 fully, to be in position B and after unit 2 has inserted unit 1, to move on to position A.
Now, will be described below image recording structure according to second embodiment of the present invention.With reference to figure 12A, device 100 has such structure, but sheet material removes in the device 370AA retraction lid 381.These device others are similar to first embodiment.
Figure 11 and 12 is the side cross-sectional, view that show the relevant portion of fixing device 37.In Figure 11, second unit 2 inserts in the first module 1 fully.In Figure 12, pull out from unit 1 unit 2.
Sheet material removes the end that device 370AA is installed in moving element 371AA.Element 371AA rotatably supports around turning axle 372AA, and described turning axle 372AA approximately is positioned at its center.Axle 372AA is by preventing that the thermal-radiating shell 500 from roller 37A etc. from supporting.Shell 500 is fixed on the unit 2 and therefore moves with unit 2.Element 371AA rotation is moved so that sheet material removes between device 370AA contact position P shown in Figure 12 and the retracted position Q.When unit 2 inserted in the unit 1 fully, shell 500 was as the part of the shell (not shown) that covers whole fixing device 37.
From top view, the comb that lid 381 likeness in form have plurality of teeth.Sheet material removes device 370AA and is withdrawn in the opening between the tooth.Element 382 will cover 381 and remain on its bottom.Element 382 is supporting on the guide rail (not shown) of end attached to it slidably along the direction of arrow Z.Guide rail is supported by shell 500.Element 382 is pushed the direction of warm-up mill 37A to by the spring 390 that is attached to element 371AA, is exactly the direction opposite with arrow Z.
In unit 1, be provided with pressure elements 395 towards shell 500 ground.Element 395 is to be used to press to the plate that is formed on the protruding 381A that covers 381 tops.Element 395 is as preventing to cover the barrier element that the 381 edges direction opposite with arrow Z shifts out.Spring 390 and element 395 common shell mechanisms corresponding to claim.Spring 390 is also corresponding to the thrust unit of claim.
Pull out from unit 1 when becoming state among Figure 12 with the state-transition in Figure 11 when unit 2, sheet material removes device 370AA away from roller 37A, that is, move along the direction of arrow Z.Simultaneously, lid 381 thrusts by spring 390 move in the direction opposite with arrow Z.This causes a end at the lid 381 of the side of roller 37A to navigate to sheet material removing between device 370AA and the roller 37A.
And, the rotation of the element 371AA that causes by thrust by spring 390, sheet material removes device 370AA and moves to retracted position Q from contact position P.Therefore, sheet material removes device 370AA and is fully retracted in the opening between lid 381 tooth.
When unit 2 inserted unit 1 fully with the state of the state-transition from Figure 12 in Figure 11, on the other hand, sheet material removed device 370AA and moves in the direction opposite with arrow Z.
