Cylindrical part 142a is provided with a spring function spare (for example a, disc spring) 143.One of them arm 143a of this member 143 is hooked on the lock portion 142e that is arranged on movable control member 142 back sides.The other end of the arm 143b of spring function spare 143 engages with the groove 118n that forms in the 120b1 of side.Like this, this spring function spare 143 by its elastic force along promoting movable control member 142 by the sense of rotation shown in the arrow a among Fig. 9, Figure 10 (a).Be subjected to the adjacent part 118e of the back side adjacent part 142b on the back side 142k of movable control member 142 of spring function spare 143 pushings in connection with drum frame 118.Therefore, movable control member 142 is being restricted aspect the rotating range of the direction of arrow a.
When being rotated by the direction shown in the arrow b among Fig. 9,10 (b), adjacent part 142c on the 142k and the adjacent part 118f that is located on the drum frame 118 connect overleaf at movable control member 142.Like this, movable control member 142 is being restricted aspect the rotating range of the direction of arrow b.
To the rotary manipulation of movable control member 142 be described below.
In this embodiment, the setting of spring function spare 143 is not inevitable.For example, can be by between the slidingsurface of the back side 142k of drum frame 118 and movable control member 142, providing relatively large friction force or by adopting buckle syndeton etc. to make movable control member 142 remain on ready position.But such as hereinafter described, it is favourable using spring function spare 143.Figure 10 (a) and (b) demonstrate such state, wherein movable control member 142 rotates along the direction of arrow a and along the direction of arrow b.In the state of Figure 10 (a), movable control member 142 rotates and remains on ready position along the direction of arrow a.In this dormant state, the exposed region 141c of input electric contact member 142 is covered by movable control member 142.In the state shown in Figure 10 (b), movable control member 142 rotates along the direction of arrow b.In this state, exposed region 141c exposes.
When handle box B was not installed in appropriate position among the equipment master component A, movable control member 142 had been taked the position shown in Figure 10 (a).In this state, the electric contact 141a that is positioned at exposed region 141c place is covered by movable control member 142.Therefore, prevented that operating personnel from meeting exposed region 141c because of carelessness and especially importing electric contact 141a.In addition, prevent that foreign object from depositing there.
Here, needn't cover exposed region 141c by movable control member 142.This will be described below.
(5) charging output contact member 144
To the charging output contact member 144 that be located among the equipment master component A be described below.
As Figure 11 (a) with (b), on the interior plate 145 of equipment master component A, be provided with and import the charging output contact member (output contact member) that electric contact 141a contacts, be used for applying charging voltage to input electric contact 141a.
Charging output contact (output contact) 144a as the part of output contact member 144 contacts with input electric contact 141a.When handle box B was not installed among the equipment master component A, output contact 144a was placed on the advanced position place as the inner side 145e outside of the side plate 145 among the equipment master component A.That is to say that output contact 144a is in the advanced position place that is positioned at 145e back, side, thereby it does not extend among the 130a of handle box mounting portion.
Like this, even operating personnel are inserted among the equipment master component A its hand so that master component A is carried out attended operation etc., hand also is not easy to meet especially output contact 144a of output electrical connecting member 144.Therefore, protected contact member 144 and electric contact 144a to avoid being subjected to the influence of foreign object deposition.Also have, it is impaired to protect them to avoid.Operating personnel may run into contact member 144 and electric contact 144a because of carelessness, thereby the static discharge that causes circuit E (will be described below) can be recharged human body damages.This damage is avoidable.Therefore, can improve the reliability of the electrical connection between handle box B and equipment master component A.
In addition, output contact member 144 is electrically connected with circuit (voltage source circuit) E (Figure 16) on being arranged on circuit board EC by lead.More particularly, output contact 144a can move between the advanced position of electrically connecting position withdrawal at electrically connecting position and its, and is placed among the 130a of handle box mounting portion, and output contact 144a is electrically connected with voltage source S (Figure 16) by circuit E.
As being clear that in Figure 11-13 (a) and (b), but side plate 145 is provided with a fixing engagement member 146, and it is fixed on the side plate 145 and towards handle box mounting portion 130a stretches out.But be provided with the removable bonding part 147c (Figure 13 (b)) at an end place that is formed on movable member 147 at this fixing engagement member 146 with respect to the place, downstream of the installation direction X of handle box B, and it stretches to mounting portion 130a by the opening 145a1 that is formed in the side plate 145.
More particularly, this movable member 147 is provided with removable bonding part 147c.Movable member 147 moves output contact 144a between advanced position and electrically connecting position.But bonding part 147c is arranged on fixing engagement member 146 with respect to the downstream that handle box B is inserted into the direction of insertion X among the equipment master component A.In other words, but at least a portion bonding part 147c is arranged on engagement member 146 back with respect to direction of insertion X.
Therefore, even operating personnel also can reduce the possibility that hand is met bonding part 147c because of carelessness for equipment master component A being carried out the purpose of attended operation and its hand being inserted among the master component A of equipment.Therefore, prevent that output contact 144a from not moving to electrically connecting position in handle box B is installed in state on the 130a of mounting portion.Like this, can provide above-mentioned advantageous effects.
By this structure, as Figure 11 (a) with (b), bonding part 147c moves explicitly along the direction of arrow c or the direction of arrow d and the installation and removal of handle box B.
Shown in Figure 11 (b), in the process that handle box B is installed among the equipment master component A, promote bonding part 147c along the direction of arrow c by movable control member 142 (Figure 10).So the output contact 144a that is associated with the operation of the movable member 147 with bonding part 147c enters suddenly in handle box mounting portion 130a or the space by the opening 145a2 that forms in side plate 145.
Like this, in the process that handle box B is installed among the equipment master component A, this output contact 144a contacts with input electric contact 141a.Therefore, charging roller 108 can be arranged on the voltage of the control operation ground reception of the CPU200 (Figure 16) among the circuit board EC from equipment master component A by circuit E response.
When handle box B not being placed among the equipment master component A, the movably direction motion of bonding part 147c arrow d in Figure 11 (b) under the effect of the elastic force that produces by spring function spare (for example compression spring) 149 (Figure 13 (b)).The operation of all-in-one-piece movable member 147 is associated with it, and output contact 144a retracts to the outside of side plate 145, that is, and and with respect to side plate 145 relative with mounting portion 130a (Figure 11 (a)).As from intelligible Figure 11 (a), bonding part 147c is subjected to the restriction at the edge of the opening 145a1 of formation in side plate 145 along the moving of direction of arrow d.When among the slave unit master component A handle box B being removed, the operation of element and motion with install or the insertion operating process in those operations and the reverse movement of element.
(6) inner structure of equipment master component A
With reference to Figure 12 the inner structure of this equipment master component A is described below.Figure 12 is from front side D, that is, and and the front view of the inside of equipment master component A when the direction of installing process cartridge B (Fig. 3) is seen.
At the inner bottom surface of this equipment master component A, that is, on the bottom surface of handle box mounting portion 130a, be provided with a circuit board EC (Figure 16).On the transverse side of mounting portion 130a with respect to installation direction, outside at the medial surface 145e of interior plate 1 45 is provided with a motor M and a driving gear set (driving force transfer device) M1, and this gear set is used for driving force is passed to connector 134 etc. from engine M.
At the relative transverse side of mounting portion 130a, but movably bonding part 147c is arranged on the downstream part of fixing engagement member 146 to the direction of insertion X of equipment master component A with respect to handle box B.In addition, as seeing along direction of insertion X, but at least a portion bonding part 147c is overlapping with fixing engagement member 146.In other words, as seeing along direction of insertion X, but a part of bonding part 147c is positioned at the back of fixing engagement member 146.
For this reason, even operating personnel are inserted into its hand the equipment master component A from front side D for the purpose of safeguarding (jam cleaning operation etc.) after having removed handle box B, but the engagement member 146 that hand also can be fixed blocks.Therefore, having prevented that movably bonding part 147c is operated personnel runs into absent-mindedly.The output contact 144a (not shown in Figure 12) that has prevented to be arranged in the advanced position moves to the electrical connection section office because of carelessness.
(7) operation of movable control member and charging output contact member
To the operation of movable control member 142 and charging output contact member 144 be described below.Figure 13-Figure 15 is the synoptic diagram of the operation when being inserted into handle box B in the imaging device 100.
Figure 13 (a), Figure 14 (a) and Figure 15 (a) view for seeing along 145 direction from mounting portion 130a to side plate, that is, and the view of seeing along the direction of the arrow Y in Figure 11 (a).Figure 13 (b), Figure 14 (b) and Figure 15 (b) are respectively the view of seeing along the direction of the arrow Z in Figure 13 (a), Figure 14 (a) and Figure 15 (a).
As understanding from these accompanying drawings, movably bonding part 147c is installed in rotation on (side plate 145 side relative with the side with mounting portion 130a relatively) on the outside of side plate 145.Movably bonding part 147c can rotate around shaft portion 147a.
Output contact member 144 is installed on the supporting member 148.Supporting member 148 is installed on the mounting portion 145b of side plate 145, so that rotate around shaft portion 148a.Promote supporting member 148 by the elastic force that produces by spring function spare (for example compression spring) 149 along the direction (Figure 13 (b)) of arrow e.Movable member 147 and supporting member 148 abut against each other at its adjacent part 147b, 148b place.Therefore, movable member 147 and supporting member 148 connection that is relative to each other.
By by the direction promotion supporting member 148 of spring function spare 149 (Figure 13 (b)), movable member 147 is rotated along the direction of arrow f along arrow e.Then, the edge of the opening 145a1 of adjacent part 147d and side plate 145 leans.Thus, movable member 147 is correctly located.At this moment, output contact 144a is arranged in the advanced position, and in this position, it does not stretch out the inside that side plate 145 enters into equipment master component A, that is, and and the electrically connecting position retraction that output contact 144a is electrically connected with input electric contact 141a from output contact 144a.In other words, output contact 144a is arranged on the outside of mounting portion 130a.Therefore, spring function spare 149 is used for flexibly pushing movable member 147 so that output contact 144a moves to advanced position and it is remained there from electrically connecting position.
Figure 13 (a) and 13 (b) demonstrate at the status of processes that handle box B is inserted among the equipment master component A.Say that more specifically in Figure 13 (a) and 13 (b), handle box B has been inserted into such position, but wherein movable control member 142 is just in time with before fixing engagement member 146 contacts.Pressing the direction of arrow X inserts handle box B along leader 130L1,130L2 are installed.
As mentioned above, movable control member 142 direction (Figure 13 (a)) along arrow j under the effect of the elastic force that is provided by spring function spare 143 is pushed.The adjacent part 142b and the adjacent part 118e of movable control member 142 lean.As mentioned above, output contact 144a is maintained in the advanced position, and it does not reach outside the side plate 145 and enters mounting portion 130a there.
In Figure 14 (a) and (b), handle box B is further inserted from position as shown in figure 13.In the state of Figure 14, but the first bonding part 142f of movable control member 142 contacts with the bonding part 146a of the engagement member of fixing 146.Like this, movably control member 142 is along with the further insertion of handle box B begins to rotate along the direction of arrow k (Figure 14 (a)).Like this, control member 142 moves with respect to drum frame 118 (handle box framework).This makes adjacent part 142b separate with adjacent part 118e.
By of the motion of movable control member 142 with respect to drum frame 118, movable control member 142 moves or turns to such position, promptly, movable control member 142 can be in the bonding part 146 below by, and the second bonding part 142d is against bonding part 147c (Figure 14 (a)) movably.Therefore, when handle box B being inserted among the equipment master component A, be rotated thus but make the first bonding part 142f and fixing engagement member 146 join to merging, the second bonding part 142d that therefore makes at the free end of control member 142 moves to the position that engages with bonding part 147c.
Along with the further insertion of handle box B, the second bonding part 142d promotes the bonding part 147c of movable member 147.This makes movable member 147 rotate along the direction of arrow g (Figure 14 (b)).Thus, supporting member 148 is rotated along the direction of arrow h (Figure 14 (b)).Therefore, make output contact 144a reach the inside of side plate 145 outsides and access arrangement master component A, that is, put in the handle box mounting portion 130.
Like this, control member 142 is by rotating with contacting of bonding part 146a, thus it can engagement member 146 below by.
When but engagement member 142d engages with bonding part 147c, but control member 142 breaks away from engagement member 146 and does not contact with it.Therefore, but the motion of control member 142 is not subjected to the restriction of engagement member 146, thereby the second bonding part 142d can engage with bonding part 147c reliably.
On the other hand, movable control member 142 moves to the position that makes contact 141a expose (Figure 10 (b)) from the position that covers input electric contact 141a (Figure 10 (a)).
Figure 15 (a) and 15 (b) demonstrate the state that handle box B wherein is inserted into the complete installation position among the equipment master component A further.Along with the insertion of handle box B, the second bonding part 142d rotates movable member 147 along the direction of arrow g (Figure 15 (b)) further.Associated ground, output contact 144a further puts in outside side plate 145 among the equipment master component A.Then, output contact 144a is contacted with the input electric contact 141a of exposure.At this moment, but but movable control member 142 engagement member 146 below by and separate with fixing engagement member 146.Movable control member 142 receives the reacting force along the direction of arrow i (Figure 15 (a)) from movable member 147, adjacent part 142c and adjacent part 118f are leant and is correctly located.
Therefore, movable control member 142 is movable with respect to drum frame 118 (handle box framework).When handle box B being inserted among the equipment master component A, but movable control member 142 engages with fixing engagement member 146 on being fixed on equipment master component A and moves with respect to drum frame 118.With after but the engagement member of fixing 146 engages, it engages so that output contact 144a overcomes the elastic force of spring function spare 149 with the bonding part 147c of movable member 147 and moves to electrically connecting position from advanced position at movable control member 142.Say that more specifically when being inserted into handle box B in the equipment master component, control member 142 engages with engagement member 146, but and make engagement member 146 move to advanced position to allow further to insert handle box B with respect to drum frame 118.Control member 142 with engage to promote movably bonding part 147c with bonding part 147c movably after engagement member 146 engages.Thus, make contact 144a move to electrically connecting position from advanced position.
Movable control member 142 also comprises the spring function spare 143 that is used for applying to movable control member 142 elastic force, and when but it engaged with the engagement member of fixing 146, movable control member 142 overcame the elastic force ground of spring function spare 143 with respect to drum frame 118 motions.
But movable control member 142 comprises the first bonding part 142f that can engage with fixing engagement member 146 and the second bonding part 142d that can engage with bonding part 147c movably.When movable control member 142 is inserted among the equipment master component A, but movable control member 142 moves with respect to drum frame 118 with fixing engaging of engagement member 146 by the first bonding part 142f.At the first bonding part 142f with after but fixing engagement member 146 engages, bonding part 147c by the second bonding part 142d and movable member 147 engages, and movable control member 142 makes output contact 144a move to electrically connecting position from advanced position.
Electrically connecting position in this instructions is a position that input electric contact 141a and output contact 144a are electrically connected mutually.Say that more specifically it is the position that input electric contact 141a and output contact 144a are electrically connected mutually when being installed to handle box B on the 130a of mounting portion.
Advanced position is output contact 144 residing positions when handle box B is not placed among the equipment master component A.Be in the contact under the situation of advanced position, when operating personnel's access arrangement master component A such as hand, compare when hand etc. are in electrically connecting position with electric contact 144a and meet contact 144a not too easily.Therefore, when electric contact 144a was in advanced position, hand was run into the possibility of contact 144a less than the possibility when electric contact 144a is in electrically connecting position.In this manual, show some embodiment, wherein advanced position is arranged in the outside (relative with mounting portion 130a with respect to side plate 145) of the medial surface 145a of the side plate 145 that is located at equipment master component A, perhaps electric contact 144a is configured to respect to hood section 171 relative with mounting portion 130a (embodiment 2), perhaps electric contact 144a is set at (embodiment 9) between the vertical panel 145f, but this is not determinate, but other position can be arranged, as long as they satisfy above-mentioned condition.
As mentioned above, according to this embodiment, in this embodiment, when among the master component A that handle box B is inserted into equipment, the operation of output contact 144a by movable control member 142, movable member 147 and supporting member 148 that has remained on the advanced position contacts with input electric contact 141a.By the control of CPU200 (Figure 16), provide voltage by circuit E, output contact 144a and input electric contact 141a to charging roller 108 from voltage source S (Figure 16).In the present embodiment, voltage source S and electric contact 144a are electrically connected by circuit E always mutually.
Input electric contact 141a contacts with the output contact 144a that is located at the electrically connecting position place and is used for operating the voltage of charging roller 108 (described treating apparatus) with reception.
(8) circuit board (circuit E)
With reference to Figure 16 the circuit board EC that is located in the present embodiment among the equipment master component A is described below.Circuit board EC be arranged on handle box mounting portion 130a below.Circuit board EC comprises CPU200 and circuit E (voltage source circuit).
Circuit board EC more specifically says, circuit E is connected with voltage source S.Circuit E is made of charging bias circuit E1, development bias circuit E2 and transfer printing/charging bias circuit E3.
Charging bias circuit E1 produces negative dc voltage and AC voltage.It applies voltage with the form of the summation of these voltages to charging roller 108.Charging roller 108 receives this voltage and gives photosensitive drums 107 chargings.
Charging bias circuit E1 also applies negative dc voltage by driven roller 105c to fixing roller 105b.Development bias circuit E2 produces negative dc voltage and AC voltage.Developer roll 110 is provided to be the voltage of form of the summation of these voltages.Developer roll 110 receives this voltage to make latent electrostatic image developing with developer.Transfer bias circuit E3 produces the dc voltage of plus or minus.It applies the dc voltage of plus or minus to transfer roll 104.
Therefore, voltage is provided for charging roller 108 from voltage source S by charging bias circuit E1.Voltage is provided for fixing roller 105b and driven roller 105c from voltage source S by charging bias circuit E1.Voltage is provided for developer roll 110 from voltage source S by development bias circuit E2.Voltage is provided for transfer roll 104 from voltage source S by transfer printing/charging bias circuit E3.
These circuit E1, E2, E3 are in response to be carried out open and close control from the instruction that is located at the CPU200 on the circuit board EC.
As mentioned above, according to present embodiment, even operating personnel are inserted into its hand among the master component A of equipment for the purpose of removing paperboard (from master component A recording materials 102 being removed) or attended operation when recording materials 102 are stuck among the master component A, output contact 144a also is difficult for being run into by hand.This is because make output contact 144a retract to advanced position.Therefore, (1) makes output contact 144a avoid being subjected to the influence of foreign object (being deposited on hand developer, grease, sweat etc.) deposition.Grease on the parts in equipment master component A or developer operating personnel's the hand of may making dirty, and if this occurs, then their output contact 144a that makes dirty easily.(2) or, output contact 144a can not damage.(3) or, can prevent that element in the circuit E of equipment master component A (Figure 16) is subjected to the destruction that may be caused by static noise.This is because the static of human body can be applied on the output contact 144a.But, can avoid static noise according to present embodiment.
Therefore, can suppress deficiencies in electrical conductivity by (1), (2) and (3) from voltage source S (Figure 16) to charging roller 108.Like this, can improve the reliability of the electrical connection between output contact 144a and input electric contact 141a.
As mentioned above, but the bonding part 147c of movable member 147 is arranged on the downstream of fixing engagement member 146 with respect to direction of insertion X, and when direction of insertion X sees, but at least a portion bonding part 147c is arranged on the downstream of fixing bonding part 146.That is, when the direction of direction of insertion X is seen, but at least a portion bonding part 147c is arranged on the back of engagement member 146.Therefore, though operating personnel for attended operation for example jam cleaning etc. purpose and its hand is inserted among the master component A of equipment, meet bonding part 147c but engagement member 146 also can prevent hand effectively.
Therefore, the output contact 144a that can avoid being placed on the advanced position moves to electrically connecting position because of carelessness.
As mentioned above, in the process of the master component A that handle box B is inserted into equipment, bonding part 147c overcomes the elastic force of spring function spare 149 and moves.
Therefore, can cushion or alleviate by handle box B being inserted into impact or the collision on handle box B when being installed on the 130a of mounting portion among the equipment master component A by this elastic force.Thus, can be reduced in impact or the vibration that receives by handle box B slave unit master component A when being installed on the 130a of mounting portion.
This is with regard to the equipment master component A that prevented from effectively to cause owing to this impact and the damage of handle box B.In addition, can prevent developer from handle box B to external leakage.In addition, can be reduced in contact portion between output contact 144a and the input electric contact 141a or the impact on the adjacent part.This has prevented the damage of contact member 141,144 effectively.
In addition, according to the embodiment of front, movable control member 142 towards the front side, promptly is subjected to flexibly pushing along the direction opposite with direction of insertion X under the effect of the elastic force of spring function spare 143.When handle box B being inserted among the equipment master component A, control member 142 overcomes elastic force and moves.Therefore, can reduce to impact by this elastic force.The summation of the elastic force that in this case, can be by spring function spare 143 and the elastic force of spring function spare 149 is slowed down impact.Therefore, can greatly reduce the counter productive of impacting.
In a word, this embodiment can provide following favourable effect:
(1) even operating personnel is for purposes such as jam cleaning operations and its hand is inserted in the master component of imaging device when handle box is not installed in the equipment master component, electric contact also is difficult for being run into by hand, because output contact does not stretch into the inside of equipment master component A outside medial surface.See as direction in along the master component that handle box is inserted into imaging device, but can protect the movably bonding part of output contact to be arranged on the back of the rear surface of being fixed in the fixing engagement member on the master component effectively.Therefore, operating personnel can not run into the movably bonding part in the equipment master component easily yet.Therefore, the deficiencies in electrical conductivity that can avoid the deposition owing to sweat or grease or analog to cause.In addition, can protect the output contact member in the equipment master component to avoid static noise, therefore can avoid the element of the circuit in the equipment master component to break down.
(2) be associated with the installation and removal operation of handle box by the motion that makes movable control member, operating personnel needn't specially do some thing so that contact these electric contacts.
(3) contact member is arranged on the side place relative with driving side, therefore can effectively utilize the space in the master component of imaging device, has realized the miniaturization of equipment thus.
(4) electric contact of handle box is arranged on lower position, thereby has improved assembly performance.In this case, move upward by making movable control member, this movable control member can not stretch out towards the master component of imaging device, thereby can reduce the size of the master component of this imaging device.
(5) movable control member rotates around axle, therefore can make the motion of movable control member in the master component that handle box is installed in imaging device or when therefrom removing steady.
(6) since movable control member close with being coupling, so carry out assembly manipulation easily.
(7) movable control member is subjected to the pushing that spring function spare for example reverses disc spring, and in the master component that handle box is inserted into imaging device the time, this movable control member overcomes elastic force and moves.Can reduce to act on the impact when being installed to handle box on the imaging device master component as far as possible.Like this, can prevent that the master component of this imaging device and/or handle box are impaired, and/or prevent that developer from leaking.By alleviating the impact on the adjacent part between the electric contact of the electric contact of master component and handle box, can avoid contact member impaired.
(8) under the situation of the rotating shaft coaxle of movable control member and photosensitive drums, needn't use extra turning axle, thereby can reduce the size of this handle box.By movable control member is arranged on the side, improved assembly performance.
