In above-mentioned first state, when toner Cartridge side handle part 91 and tilting member 92 were kept together, tilting member 92 overcame the elastic force of elastic component 128 around inserting axle 37 along being rotated counterclockwise.After toner Cartridge side handle part 91 and tilting member 92 were kept a period of time together, the swing of tilting member 92 stopped.This state of tilting member 92 is called as second state below.
In second state, as shown in Figure 9, first junction surface 132 of aforementioned first restrictions 94 and inner housing 42 the 4th radially teat 99 separate, first junction surface 132 with the 4th radially engaging of teat 99 thrown off.Yet the rearward end of second restrictions 95 contacts with the inner round wall 51 of inner housing 42, and inner housing 42 is limited with respect to the rotation of shell body 41.
Therefore, when tilting member 92 is in the third state between first state and second state, first junction surface 132 with the 4th radially engaging of teat 99 thrown off, and the rear end part of other second restrictions 95 does not contact with the inner round wall 51 of inner housing 42, inner housing 42 is disengaged with respect to the restriction that shell body 41 rotates, shown in Fig. 3 and 10.In this case, when inner housing 42 rotates with respect to shell body 41, each laterally projecting 54 is directed to corresponding insertion groove 127, each second radially teat 57 be directed to the corresponding gathering sill 129 of going up, each the 3rd radially teat 63 be directed to corresponding gathering sill 130 down, shown in Fig. 5 (b).When inner housing 42 rotated with respect to shell body 41, the first radially inner surface sliding contact of teat 48 and the cylindrical wall 45 of shell body 41 of inner housing 42 made shell body 41 and inner housing 42 keep airtight and watertight, as shown in Figure 3 thus.
And, as Fig. 5 (b) with shown in 8, when tilting member 92 is in the third state, inner housing 42 can turn to the toner off-position, at this moment, second toner discharging port 55 of inner round wall 51 is blocked by the part of the cylindrical wall 45 of shell body 41, is different from first toner discharging port 49, and the interior section of shell body 41 and inner housing 42 is sealed.At this moment, each second radially teat 57 contact with the corresponding upper end-face edge of going up gathering sill 129, each the 3rd radially teat 63 contact with the corresponding upper end-face edge of gathering sill 130 down, each laterally projecting 54 contacts with the front edge of insertion groove 127 accordingly.In addition, inner housing 42 can turn to the toner release position, at this moment, by first toner discharging port 49 and second toner discharging port 55 being turned to the position faced mutually the interior section of shell body 41 and inner housing 42 is discharged, shown in Fig. 5 (a).At this moment, each second radially teat 57 contact with the corresponding lower limb of going up gathering sill 129, each the 3rd radially teat 63 with corresponding under the lower limb of gathering sill 130 contact, each laterally projecting 54 contacts with the back edge of insertion groove 127 accordingly.
In inner housing 42, include as developer can anodal charging, nonmagnetic monocomponent toner.Toner adopts polymerization toner.Polymerization toner can be by methods such as suspension polymerizations with polymerisable monomer, and as styrene monomer such as styrene, acrylic monomers such as acrylic acid, alkyl (C1-C4) acrylates and alkyl (C1-C4) methacrylate carry out copolymerization and obtain.It is spherical that polymerization toner is generally, and has excellent flowing, can obtain high-quality image and form.
In this toner, be mixed with pigment as carbon black or wax and so on.In order to increase flowability, also added adjuvant in addition as tripoli and so on.Toner has the average particle size particle size that is approximately 6-10 μ m.
(b-4) toner Cartridge is to the installation and the dismounting of processing unit
(b-4-i) toner Cartridge attached to processing unit
Be in a disengaged position and flashboard 111 is in the toner Cartridge container cavity 71 of the processing unit 20 of developer off-position state for ON/OFF bar 113, as shown in Figure 8, wherein inner housing 42 tiltedly descends rear side to tilt to be mounted at the toner Cartridge 40 of toner blocking position from the side direction of tiltedly going forward.At this moment, as shown in Figure 6, each positioning salient 131 of toner Cartridge 40 is directed in the corresponding gathering sill 119 of toner Cartridge container cavity 71 of processing unit 20.In addition, the tilting member 92 of toner Cartridge 40 is in first state, and inner housing 42 is limited with respect to the rotation of shell body 41.
When each positioning salient 131 arrived the deepest part of corresponding gathering sill 119 and contacts with the deepest part, laterally projecting 54 of each of toner Cartridge 40 engaged with the corresponding acceptance division 117 of ON/OFF bar 113 at disengaged position, as shown in Figure 7.At this moment, as shown in Figure 9, toner Cartridge 40 each second radially teat 57 engage with the corresponding joint 139 of the flashboard 111 of toner Cartridge container cavity 71, and flashboard 111 by corresponding second radially teat 57 and the 3rd radially teat 63 on rotation direction, clamp.At this moment, when having second radially during teat 57, each the 3rd radially teat 63 engage with flashboard 111.When second junction surface 133 engaged with junction surface 124, tilting member 92 was in third state (see figure 10).
The positioning rib 137 of toner Cartridge 40 is mounted in the locating slot 138 of processing unit 20 and with developing body housing 62 and engages, as shown in Figure 7.So, in toner Cartridge 40, shell body 41 is positioned on Width with respect to toner Cartridge container cavity 71, and toner Cartridge 40 is done to the installation of handling unit 20.Under this state, in the handle part 118 and the toner Cartridge side handle part 91 of toner Cartridge 40 of the ON/OFF bar 113 of the disengaged position predetermined spacing of being separated by, and be positioned at the below of toner Cartridge side handle part 91, as shown in Figure 9.In addition, shown in Figure 11 (b), the contact site 143 of each contact teat 141 of processing unit side handle part 110 in the face of and slightly contact with each guide surface 146 that is touched portion 142 accordingly in the toner Cartridge 40.
As shown in Figure 7, be installed into fully at toner Cartridge 40 under the state of processing unit 20, tilting member 92 is in the above-mentioned third state, so inner housing 42 rotates with respect to shell body 41.Therefore when ON/OFF bar 113 (see figure 2) when disengaged position forwards contact position to, inner housing 42 rotates with ON/OFF bar 113 (processing unit side handle part 110), turns to toner release position (see figure 3) from toner off-position (see figure 10).Therefore, first toner discharging port 49 is faced mutually with second toner discharging port 55, as shown in Figure 3.In addition, by inner housing 42 second radially teat 57 and the 3rd radially the flashboard 111 clamped of teat 63 with inner housing 42 rotations, turn to the developing body release position from developing body off-position (see figure 9), and the toner targeting port 88 of the through hole 112 of flashboard 111 and toner Cartridge container cavity 71 faces one another.In addition, go to contact position in company with ON/OFF bar 113 from disengaged position, processing unit side handle part 110 upwards rotates, and makes handle part 118 near toner Cartridge side handle parts 91 thus.
In toner Cartridge container cavity 71, flashboard 111 is in the developing body release position, and in toner Cartridge 40, inner housing 42 is in the toner release position, and first toner discharging port 49 that faces one another in the through hole 112 that faces one another in toner Cartridge container cavity 71 and toner targeting port 88 and the toner Cartridge 40 and second toner discharging port 55 face one another and communicate with each other.As a result, by toner targeting port 88, through hole 112, first toner discharging port 49 and second toner discharging port 55, the interior section in the interior section of the inner housing 42 of toner Cartridge 40 and the development chamber 72 of development section 30 interconnects.
As mentioned above, since the space between the shell body 41 that first toner discharging port 49 is formed thereon and second toner discharging port 55 inner housing 42 formed thereon by first radially teat 48 remain on airtight and the watertight state, because seal member 125 extend in the space between through hole 112 flashboard 111 formed thereon and toner targeting port 88 curved wall 122 formed thereon, can avoid toner from toner targeting port 88, through hole 112, first toner discharging port 49 and second toner discharging port 55, to leak to the outside again.
As mentioned above, when processing unit side handle part 110 rotates with the rotation of ON/OFF bar 113 from the disengaged position to the contact position, the contact site 143 of each contact teat 141 of processing unit side handle part 110 is through being touched the guide surface 146 of parts 142, upwards rotate along being touched surface 147 then, through a plurality of portions 144 that are touched, shown in Figure 11 (a).
Be recessed shape because contact site 143 is to protrude shape and be touched portion 144, therefore when contact site 143 processes are touched portion 144, can produce swing, swing can pass to the inner round wall 51 of flashboard 111 then.In other words, contact site 143 and be touched portion 144 as the swing applying units.
When ON/OFF bar 113 when the rotation of contact position is finished, 144 uppermost position in fig-ure is in contact with it the contact site 143 of processing unit side handle part 110 at the junction surface.At this moment, the contact pressure when being in a disengaged position (seeing Figure 11 (b)) by being higher than ON/OFF bar 113, contact site 143 is resisted against each and is touched parts 142 from the front side." against " " contact " during with disengaged position be different.Equally, contact teat 141 (contacting with high pressure) is also against being touched parts 142.
Figure 13 is the side cross-sectional view of laser printer among Fig. 1, is presented to close in the installing port way, and the ON/OFF bar disturbs the state of protecgulum.
When processing unit 20 is mounted to main casing 2 and ON/OFF bar 113 when being in contact position, as shown in Figure 1, below processing unit side handle part 110, form a space.When protecgulum 7 is closed, so that installing port 6 is when closing, the interference part 140 of protecgulum 7 is contained in the above-mentioned space.In other words, when ON/OFF bar 113 was not in contact position, as shown in figure 13, processing unit side handle part 110 was positioned at this space, and therefore, in the way that protecgulum 7 is closed, interference part 140 contacts with processing unit side handle part 110.In other words, in the way of closing installing port 6, rather than be under the contact position situation at ON/OFF bar 113, ON/OFF bar 113 disturbs protecgulums 7.
(b-4-ii) dismounting of toner Cartridge from the processing unit
Be in the developing body release position and inner housing 42 is under the state of toner release position at flashboard 111, the ON/OFF bar 113 that is in contact position turns to disengaged position as shown in figure 10.Rotation with ON/OFF bar 113 (processing unit side handle part 110), inner housing 42 forwards the toner off-position to from the toner release position, and second toner discharging port 55 of inner round wall 51 is blocked by the part on the cylindrical wall 45 on the shell body 41, and be different from first toner discharging port 49, with interior section sealing with shell body 41 and inner housing 42.In other words, with the rotation of inner housing 42, second radially teat 57 and the 3rd radially teat 63 rotate, and by second radially teat 57 and the 3rd radially the flashboard 111 clamped of teat 63 turn to off-position from the developer release position.So, the toner targeting port 88 of toner Cartridge container cavity 71 is blocked by the part of flashboard 111, and is different from through hole 112.
In addition, along with ON/OFF bar 113 turns to disengaged position, processing unit side handle part 110 rotates, therefore, the contact site 143 of processing unit side handle part 110 rotates along being touched surface 147, shown in Figure 11 (b) simultaneously through a plurality of portions 144 that are touched.When contact site 143 processes are touched portion 144, can produce above-mentioned vibration.When ON/OFF bar 113 when the rotation of disengaged position is finished, contact site 143 and guide surface 146 in the face of and slightly contact.In other words, when ON/OFF bar 113 was in a disengaged position, contact site 143 was to being touched being thrown off against state (high pressure contact) of parts 142.
Turn under the disengaged position state at ON/OFF bar 113, because first restrictions 94 is in the third state and second junction surface 133 engages with joint 124, as shown in figure 10, tilting member 92 turns to second state, and engaging between second junction surface 133 and the joint 124 thrown off, as shown in Figure 9.When tilting member 92 remains on second state (swing component 92 is held), toner Cartridge 40 is pulled out to tiltedly going up the place ahead from toner Cartridge container cavity 71.At this moment, each positioning salient 131 (see figure 6) of toner Cartridge 40 are directed in the toner Cartridge container cavity 71 in corresponding gathering sill 119 (see figure 6)s.When the toner Cartridge 40 that is drawn out was thrown off, tilting member 92 transferred the first state (see figure 8) to.
When each positioning salient 131 is thrown off from corresponding gathering sill 119, joint between each laterally projecting 54 and the corresponding acceptance division 117 is thrown off (see figure 7), each second radially the joint between teat 57 and the re-spective engagement portion 139 thrown off, toner Cartridge 40 is finished from the dismounting on the processing unit.
(b-5) development and transfer operation
As above (b-4-i) addresses shown in Figure 3ly, after toner Cartridge is mounted to processing unit 20 and is accommodated in the toner Cartridge container cavity 71, in the image of laser printer 1 forms, inputs to stirrer turning axle 53 from the driving force of motor (not shown).Then, from the left side, stirrer turning axle 53 is rotated in a clockwise direction, and in the inner space of the inner housing 42 of toner Cartridge 40, stirrer 56 along the circumferential direction moves around stirrer turning axle 53.Therefore, the toner in the toner Cartridge 40 is stirred device 56 and stirs, and is conducted to development section 30 by second toner discharging port 55 and first toner discharging port 49, is received by through hole 112 and toner targeting port 88, is discharged into then in the development chamber 72.Rotation according to stirrer turning axle 53, aforesaid wiper 50 wipings of each of stirrer 56 are located at the toner detection window (not shown) on the respective inside edge wall 52 of inner housing 42, clean toner detection window (not shown) by wiper 50 thus.
The toner that is released into development chamber 72 from toner targeting port 88 is supplied to developer roll 104 by the rotation of donor rollers 101.At this moment, toner is charged by the friction positive pole between donor rollers 101 and developer roll 104.According to the rotation of developer roll 104, supply enters into bed thickness at the toner on the developer roll 104 and regulates between the rubber rollers 106 of the press member 148 of blade 107 and developer roll 104, and is developed roller 104 in the mode with uniform thickness layer and carries.
According to the rotation of photosensitive drums 28, the positive pole charging is carried out equably by corona-type charger 29 in the surface of photosensitive drums 28, then by the laser beam lithography of high-velocity scanning self-scanning portion 19, finally is formed corresponding to the electrostatic latent image that is formed on the image on the paper 3.
After this, by the rotation of developer roll 104, be developed the toner that roller 104 carries and positive pole charges and contact face-to-face with photosensitive drums 28.At this moment, toner is supplied to and is formed on photosensitive drums 28 lip-deep electrostatic latent images, promptly by the part of laser beam lithography, and has than low potential on the surface of even anodal photosensitive drums 28 of charging.Therefore, the electrostatic latent image on the photosensitive drums 28 is rasterized, and the toner image that is reversed development is carried on photosensitive drums 28 surfaces.
Then, the toner image that carry on photosensitive drums 28 surfaces is transferred to paper 3, and paper 3 is transmitted against roller 15 (see figure 1)s and enters bulging housing 76 from first through port 84.In the process of paper 3 through the transfer position between photosensitive drums 28 and the transfer roll 31, toner image is transferred on the paper 3 by the transfer bias that is applied on the transfer roll 31.
Have be transferred toner image paper 3 outside second through port 85 outputs to bulging housing 76, and be sent to photographic fixing portion 21.
Remaining in toner on the photosensitive drums 28 after the transfer printing is developed roller 104 and regains.

In photographic fixing portion 21, in transfer position, be transferred on the paper 3 toner image paper 3 during through warm-up mills 60 and pressure roll 61 by hot photographic fixing on paper 3.Photographic fixing has the paper 3 of toner image to be transmitted roller 63 to be sent to paper and discharge to transmit passage and be sent to paper distributing roller 47 then, and finally is discharged on the paper discharge dish 58 by paper distributing roller 47.Paper discharge dish 58 is formed on the upper surface of main casing 2.
2. the operation of embodiment and effect
As mentioned above, in processing unit 20, (downstream of toner Cartridge 40 disassembly direction from the development section 30) is resisted against on the toner Cartridge 40, as shown in Figure 2 from the front side to be located at processing unit side handle part 110 on the ON/OFF bar 113 of development section 30.Therefore, though when with toner Cartridge 40 forward (disassembly direction) mobile power be applied on the toner Cartridge 40, toner Cartridge 40 can be limited with respect to relative forward the moving of development section 30.
As a result, the installment state of toner Cartridge 40 in development section 30 can be held reliably.
As shown in figure 11, ON/OFF bar 113 can rotate between contact position (seeing Figure 11 (a)) and disengaged position (seeing Figure 11 (b)), contact position be processing unit side handle part 110 against the position that firmly is installed in the toner Cartridge 40 in the development section 30, disengaged position be processing unit side handle part 110 with toner Cartridge 40 against the position that is disengaged.Therefore, when ON/OFF bar 113 was in contact position, the simple operations of rotating ON/OFF bar 113 just can keep the installment state (see figure 2) of toner Cartridge 40 in development section 30 reliably.In other words, the installment state that is kept can be disengaged and toner Cartridge 40 can be mounted to development section 30 or remove (see figure 6) from development section 30.
And, because from the state that development section 30 is removed, ON/OFF bar 113 relies on own wts and is in disengaged position below the contact position, when toner Cartridge 40 is mounted to development section 30 at toner Cartridge 40, can save the process that ON/OFF bar 113 is moved to disengaged position, as shown in Figure 8.
And, in toner Cartridge 40, by inner housing 42 being turned to the toner release position when opening cylindrical wall 45, second toner discharging port 55 is opened (seeing Fig. 5 (a)), and in development section 30, flashboard 111 is moved to the developing body release position and is opened and discharges toner targeting port 88 (seeing Fig. 4 (a)), therefore, second toner discharging port 55 and toner targeting port 88 communicate with each other, and as shown in Figure 3, toner can be supplied to development section 30 by toner Cartridge 40 thus.In other words, in toner Cartridge 40, inner housing 42 is rotated the toner off-position and is closed to close cylindrical wall 45 (see figure 10)s, therefore second toner discharging port 55 is closed, and in development section 30, flashboard 111 is moved to developing body off-position (seeing Fig. 4 (b)) and is closed, so toner targeting port 88 closes, and toner is limited by the supply of toner Cartridge 40 to development section 30 thus.
In addition, the switching manipulation of cylindrical wall 45 and flashboard 111, i.e. the rotation interlock of the mobile and ON/OFF bar 113 of rotation of inner housing 42 and flashboard 111.Therefore, the rotation of ON/OFF bar 113 can keep (see figure 2) or remove the installment state of (see figure 7) toner Cartridge 40 in development section 30, and then toner can be supplied to the supply (see figure 10) of development section 30 (see figure 3)s or restriction toner by toner Cartridge 40, thereby strengthened its operability.
In addition, the contact site shown in Figure 11 143 and be touched portion 144 and rotate at ON/OFF bar 113 and vibration can be passed to cylindrical wall 45 at least when mobile.This vibration can be shaken off the toner that adheres on 45 when the cylindrical wall 45 of opening and closing with the rotation of ON/OFF bar 113 interlock.
Particularly, when protruding shape contact site 143 and recessed shape and be touched portion 144 and contact, when vibrating the rotation that results from ON/OFF bar 113 and move.Interchangeable, contact site 143 can be recessed shape and is touched portion 144 for protruding shape.Contact site 143 and protrusion shape that is touched portion 144 or recessed shape make the oscillating action unit in vibrative while reliably, designs simplification.Be provided with a plurality of portions 144 that are touched among Figure 11, be touched portion and in Figure 12, only be provided with one.A plurality of when being touched portion 144 when being provided with, be touched and produce bigger vibration between portion 144 and the contact site 143.
In addition, as shown in Figure 2, when ON/OFF bar 113 went to contact position, the handle part of ON/OFF bar 113 118 was near the toner Cartridge side handle part 91 of toner Cartridges 40, so handle part 118 and toner Cartridge side handle part 91 can be kept together.Can stablize the relative position of 40 of the development section 30 that is provided with ON/OFF bar 113 and toner Cartridges like this, thereby the motion of stabilized treatment unit 20.
In addition, when development section 30 in main casing 2 and toner Cartridge 40 were in installment state, in the way that installing port 6 is closed, ON/OFF bar 113 contacted with protecgulum 7, and is different from the situation (see figure 1) that ON/OFF bar 113 is in contact position, as shown in figure 13.Therefore, when toner Cartridge 40 correctly is not mounted in the development section 30 (or when ON/OFF bar 113 be not in contact position), the operation of the non-expectation of laser printer 1 can be prevented from.
In addition, as shown in Figure 7, (see figure 3) when ON/OFF bar 113 is in contact position promptly is located at the both ends of processing unit side handle part 110 on vertically at Width against the contact teat 141 that is touched parts 142 of (high pressure contact) toner Cartridge 40.Be touched parts 142 are located at toner Cartridge 40 on Width both ends.
Therefore, when ON/OFF bar 113 is in bonding station, engage teat 141 and be touched parts 142 against what be located at processing unit side handle part 110 vertical both ends, can avoid the deflection of processing unit side handle part 110 and ON/OFF bar 113 thus, and then avoid the distortion of processing unit side handle part 110 and ON/OFF bar 113, improve its permanance.
Because toner Cartridge side handle part 91 is located at two of two ends on the Width of toner Cartridge 40 and is touched between the parts 142, therefore toner Cartridge side handle part 91 can be touched parts 142 and separate hand and the interference that is touched parts 142 in the time of can avoiding thus grasping toner Cartridge side handle part 91.
Therefore, when toner Cartridge 40 is mounted to development section 30, is touched parts 142 and on Width, does not move, and therefore when ON/OFF bar 113 is in contact position, contacts teat 141 and can be touched parts 142 against (high pressure contact) reliably.And, as mentioned above, be touched parts 142 and be located at the two end portions of toner Cartridge 40 on Width, therefore when contacting teat 141 when being touched parts 142, can avoid the deflection of processing unit side handle part 110.Therefore, can not move being located at the positioning rib 137 that is touched between the parts 142 on the Width, toner Cartridge 40 can be located reliably.
In addition, in ON/OFF bar 113, processing unit side handle part 110 is configured to it is connected with the free end (leading section) of right support portion 108 and the free end (leading section) of left support portion 109, strengthens the intensity of ON/OFF bar 113 thus.
ON/OFF bar 113 engages with laterally projecting 54, therefore makes second toner discharging port 55 with laterally projecting 54 rotation.Therefore, cylindrical wall 45 relatively rotates about second toner discharging port 55, as shown in Figure 3.In other words, flashboard 111 with rotate with respect to cylindrical wall 45 second radially teat 57 and the 3rd radially teat 63 engage, flashboard 111 rotates thus.Cylindrical wall 45 and flashboard 111 are rotated reliably and then second toner discharging port 55 and toner targeting port 88 can be opened and close reliably.
