Shown in Fig. 8 A, battery lead plate 111 is sheet metals, and its Width along drum housing 76 extends, and vertically has on the end (medial extremity of the Width of drum housing 76) at one of which and to be bent the bend of expansion forward.Another of battery lead plate 111 vertically end (outboard end of the Width of drum housing 76) is inserted and secured in the electrode installation portion 113; This electrode installation portion 113 is arranged on the right side wall 94b, and the part in vertical centre of battery lead plate 111 is engaged with in the notch part 112 of three surface members 109.Like this, battery lead plate 111 is installed on the upper shell 78, and its vertical freely end bends to arc on fore-and-aft direction.
The outside of fixing vertical end right side wall 94b on Width is exposed on of battery lead plate 111.When drum box 27 is installed in the main casing 2, be arranged on vertical end of this exposure of the terminal (not shown) contact electrode plate 111 on the main casing 2, make bias voltage be applied to battery lead plate 111 through this terminal.
Then, back up pad 66 is oriented in the face of cleaning support portion 98, and shown in Fig. 9 A and Fig. 9 B, so fore paw 110 is inserted into the preceding joint through hole 70 of joint 67 and engages with it.Because preceding joint through hole 70 engages with fore paw 110, back up pad 66 is rotated around preceding joint through hole 70, so palintrope pars convoluta 68 moves backward.Thereby the back joint through hole 71 of joint 67 is engaged on the rear solid end 114 at junction surface 104 and with rear solid end 114 and engages, shown in Figure 10 A and Figure 10 B.Like this, back up pad 66 is supported on support member 105 and the madial wall 106.As shown in Figure 7; Through the joint 67 of vertically holding (two transverse end of drum housing 76) to engage at two with junction surface 104; Back up pad 66 is supported on the upper shell 78, and simultaneously because back up pad 66 is installed between the lateral wall 107, laterally moving of back up pad 66 is restricted.
When back up pad 66 is supported on 78 last times of upper shell, the rear side of the free vertically end in contact back up pad 66 of battery lead plate 111 and promote back up pad 66 forward.As a result, when drum box 27 was installed in the main casing 2, the terminal that is arranged on the main casing 2 can be applied to back up pad 66 with bias voltage through battery lead plate 111.
(b) on lower house, install housing
As stated, the upper shell 78 that is mounted above that of cleaning element 32 is assembled on the lower house 77.
Along with charger 29 is supported on the upper shell 78; Transfer roll 31 is supported on the lower house 77; And the main drum body 33 of photosensitive drums 28 is accommodated in the lower house 77; Upper shell 78 is placed on the top of the bulging support unit 80 of lower house 77, and is as shown in Figure 4, and the through hole 116 of upper shell 78 is alignd on Width with the through hole 89 of lower house 77.Subsequently, drum axle 34 is inserted into and through being arranged on PATENT left side via 116,89 and right side through hole 116, main drum body 33 between 89.Like this, upper shell 78 is attached knot with lower house 77 through drum axle 34.
When upper shell 78 was attached to lower house 77,69 contacts of the palintrope pars convoluta of back up pad 66 were arranged on location wall 92 (see figure 2)s on the admittance plate 90 of lower house 77, therefore with respect to the fixing position of cleaning brush 65 of photosensitive drums 28.In addition, collector unit 118 is arranged on the below of cleaning brush 65.
In addition, the opening 115 diagonal line ground of upper shell 78 are positioned at the last rear of back up pad 66.Opening 115 is formed in the rear wall 95.Back up pad 66 forms between back up pad 66 and rear wall 95 at interval or the gap in the face of rear wall 95.Back up pad 66 has no in the interval of member between back up pad 66 and opening 115 in the face of opening 115.In other words, any member that does not hinder any linear communication path between back up pad 66 and the opening 115 is positioned.Back up pad 66 is communicated with outside through opening 115.In other words, can see back up pad 66 from the outside of drum housing 76 through opening 115.More specifically, shown in Figure 11 A, border imaginary line 301 is defined as the lower limb of each opening 115 of connection and the lower limb of back up pad 66.Another border imaginary line 302 is defined as the coboundary of each opening 115 of connection and the coboundary of back up pad 66.For all openings 115, have no member to be positioned in the space of definition between border imaginary line 301 and 302.Notice, for some opening 115, in the space that some parts possibly define between border imaginary line 301 and 302, as long as connecting at least one opening 115 and back up pad 66 at least one linear space by the part reservation.Guarantee that like this part of back up pad 66 can be through at least one in sight from the outside of drum housing 76 with opening 115 at least.
In addition, opening 115 by diagonal line be arranged on the last rear of collector unit 118, the connection between back up pad 66 resistance openings 115 and the collector unit 108.
Opening 115 also is provided in above the fore-and-aft direction charger 29, can reach connection between the two.Back up pad 66 is provided with along the bottom of the communication path between opening 115 and the charger 29.
Opening 115 also is set at the top of the inferoposterior wall 87 of lower house 77, and diagonal line be arranged on the last rear of cleaning element 32.When drum housing 76 when being installed in the main casing 2, opening 115 also by diagonal line be arranged on the inferoanterior of pipeline 120.
(4) rouse the operation and the effect of housing and cleaning element
In above-mentioned bulging box 27, cleaning element 32 is faced the outside of rousing housing 76 through the opening 115 that is formed in the upper shell 78.Therefore, the rear wall 95 of drum housing 76 do not stop and rear side in the face of the relative cleaning element 32 in the side of photosensitive drums 28 fully, on the contrary the rear side of cleaning element 32 through opening 115 directly with the external communications of drum housing 76.Therefore, if the inside of drum housing 76 reaches a high temperature, hot-air is not deposited in the bulging housing 76, but is dispersed into outside the bulging housing 76 through opening 115.As a result, cleaning element 32 can be through simple structure cooling, and the temperature that suppresses cleaning element 32 rises, and prevents the toner deliquescing of deposition on the cleaning brush 65, therefore prevents conjunctiva on photosensitive drums 28.
In addition, rear wall 95 covers cleaning element 32, makes cleaning element 32 through the outside of opening 115 in the face of drum housing 76 simultaneously.Cleaning element 32 is not directly exposed to the outside.Therefore, cleaning element 32 can be by rear wall 95 protections, the not member in direct contact drum housing 76 outsides.Therefore, can prevent cleaning element 32 because the member in contact drum housing 76 outsides and shift position, thereby prevent photosensitive drums 28 is caused damage.
Further, this structure of cleaning element 32 can firmly be supported on cleaning brush 65 on the back up pad 66, scrapes paper dirt from photosensitive drums 28 reliably with fiber cleaning brush 65 simultaneously.Because back up pad 66 is supported on sides relative with photosensitive drums 28 simultaneously directly in the face of opening 115 with cleaning brush 65, this structure can prevent to be cleaned paper dirt that brush 65 catches is escaped through opening 115 and is spread to the outside of bulging housing 76.In addition, the back up pad 66 that forms the sheet metal with thin type has improved cooling effect.
Because back up pad 66 is supported on the bulging housing 76 at its vertical two ends, cleaning element 32 also can be supported reliably.More specifically, joint 67 is arranged on two of back up pad 66 vertically ends, and junction surface 104 is arranged on and is used for engaging joint 67 on the upper shell 78.Therefore, the engaging of the junction surface 104 on the joint 67 through back up pad 66 and the upper shell 78, back up pad 66 can be supported reliably.
More specifically, each joint 67 of back up pad 66 comprise be arranged on back up pad 66 two vertically end go up and relative to each other preceding joint through hole 70 separated by a distance in vertical direction engages through hole 71 with the back.The junction surface 104 of each joint 67 comprise be used for preceding engage fore paw 110 that through hole 70 engages be used for after engage the rear solid end 114 of through hole 71 joints.
When cleaning element 32 was installed, preceding joint through hole 70 at first was engaged on the fore paw 110 separately and with fore paw 110 and engages.Then, back up pad 66 rotates backward around preceding joint through hole 70, and joint through hole 71 is engaged on the rear solid end 114 separately and with rear solid end 114 and engages up to the back, thereby back up pad 66 is supported on the upper shell 78.Therefore can back up pad 66 be supported on the upper shell 78 reliably through simple assembling process.
In addition, in installation process, joint can engage before being included in and insert fore paw 110 in the through hole 70 and in the joint through hole 71 of back, insert rear solid end 114 through simple structure acquisition reliably.
By this way back up pad 66 is vertically held two and be supported on any additional member that need back up pad 66 is supported on the bulging housing 76 in the zone beyond vertically holding.Therefore, through simple structure, back up pad 66 can be supported with respect to opening 115 reliably.
Employing is applied to the bias voltage of back up pad 66 through battery lead plate 111, and cleaning brush 65 can electric attraction paper dirt.In addition, because back up pad 66 is opened in cleaning brush 65 opposite sides, battery lead plate 111 can be arranged on this side and be used for promoting back up pad 66.Therefore, through simple structure, bias voltage can be applied to back up pad 66 reliably.
Back up pad 66 also is configured to stop the connection between opening 115 and the collector unit 118.Therefore, the paper dirt that is collected in the collector unit 118 is prevented from scattering through opening 115.
Because back up pad 66 is set at the bottom of the communication path between opening 115 and the charger 29, the ozone that is produced by charger 29 can be used to cooled supports plate 66 when discharging through opening 115.
Because the back holding plate 100 that on the side near opening 115, is used for keeping charger 29 is than preceding holding plate 99 outstanding short length, 115 airflow can easily be produced from charger 29 to opening.As a result, the ozone that produces from charger 29 can be discharged through opening 115 with being more prone to.
When handle box 20 was installed in the main casing 2 of laser printer 1, fixation unit 21 was disconnected from each other in the horizontal direction with photosensitive drums 28, hot-air generation heat radiation that the warm-up mill 60 from fixation unit 21 produces and the photosensitive drums 28 that flows to handle box 20.Because cleaning element 32 is being arranged on the direction of approximate horizontal between fixation unit 20 and the photosensitive drums 28, the influence that the temperature that cleaning element 32 is caused by the hot-air from fixation unit 21 easily raises.
Yet handle box 20 comprises the inferoposterior wall 87 that extends to cleaning element 32 back on the lower house 77.Therefore, inferoposterior wall 87 can prevent the hot-air contact cleaning element 32 that the warm-up mill 60 from fixation unit 21 produces.This structure can prevent that cleaning element 32 is heated.Temperature through suppressing cleaning element 32 in this way rises, and this structure prevents conjunctiva on photosensitive drums 28.
Except inferoposterior wall 87, interior rear wall 91 also is arranged on the front of inferoposterior wall 87 on the lower house 77 and parallel with inferoposterior wall 87, so inferoposterior wall 87 and interior rear wall 91 are promptly overlapping on the inboard direction in lateral at fore-and-aft direction.In other words, inferoposterior wall 87 extends with interior rear wall 91 parallel to each other, and interior rear wall 91 is positioned at the front side, promptly with respect to the inboard of inferoposterior wall 87.An interval is formed between inferoposterior wall 87 and the interior rear wall 91.This is at interval as the thermoshield chamber.Therefore, this structure further improves the thermoshield effect and prevents that further the temperature of cleaning member 32 from raising.
Shown in Figure 11 B, border imaginary line 303 is defined as the coboundary in the zone that contacts photosensitive drums 28 of the coboundary that connects inferoposterior wall 87 and cleaning brush 65.Another border imaginary line 304 is defined as the lower limb in the zone that contacts photosensitive drums 28 of the lower limb that connects inferoposterior wall 87 and cleaning brush 65.Interior rear wall 91 is from admitting plate 90 projections, and the coboundary of interior rear wall 91 is between boundary artefacts straight line 303 and 304.Yet interior rear wall 91 can change from the overhang of admitting plate 90, and the coboundary of rear wall 91 is higher than border imaginary line 303 in making.The overhang of interior rear wall 91 can freely change, if in the coboundary of rear wall 91 on the border imaginary line more than 304.
Through be provided with cleaning element 32 make its pass through opening 115 with the drum housing 76 the outside directly be communicated with; Has no member between cleaning element 32 and opening 115; The hot-air that produces in the fixation unit 21 is not trapped within the bulging housing 76, but diffuses to outside the bulging housing 76 through opening 115.Therefore, the temperature of this OILS STRUCTURE DEPRESSION cleaning element 32 raises, and prevents conjunctiva on photosensitive drums 28.
More specifically; Through above the inferoposterior wall 87 in lower house 77 opening 115 being set; Inferoposterior wall 87 prevents that the hot-air in drum housing 76 outsides from impacting cleaning element 32, and drum housing 76 inboard hot-airs can diffuse to outside the bulging housing 76 through opening 115, therefore cool off cleaning element 32 effectively.As a result, the temperature of this OILS STRUCTURE DEPRESSION cleaning element 32 raises and prevents conjunctiva on photosensitive drums 28.
Form opening 115 through rear on cleaning element 32 cornerwise, the hot-air that rises around the cleaning element 32 can be discharged through opening 115 effectively.In laser printer 1, hot-air generation heat radiation that the warm-up mill 60 from fixation unit 21 produces and the photosensitive drums 28 that flows to handle box 20.Yet because the upstream end portion 120b of pipeline 120 is arranged between fixation unit 21 and the handle box 20, pipeline 120 can be guided hot-air into exhaust fan 119, and exhaust fan 119 is discharged hot-air outside the main casing 2 simultaneously.Therefore, this structure further prevents cleaning element 32 heating.
In addition, when handle box 20 was installed in the main casing 2, opening 115 diagonal line ground were positioned at the inferoanterior of pipeline 120.Therefore, the hot-air of drum in the housing 76 can pass opening 115 and discharged through pipeline 120 guiding and by exhaust fan 119, and the hot-air that flows to photosensitive drums 28 from fixation unit 21 simultaneously can be discharged through pipeline 120 guiding and by exhaust fan 119.Therefore, this structure is discharged hot-air effectively from main casing 2.
3. the structure of positioning box
