As shown in Figure 6, laser printer 1 position that developer box 28 will be installed in cabinet 2 comprises drive unit 110 and box-like condition and type detector 120.Drive unit 110 is configured to driving force is passed to the input gear 62 of developer box 28.It is new or with crossing that box-like condition and type detector 120 are configured to detect the developer box of being installed 28, and detects the type of the developer box of being installed 28.New reagent box 28 never is used to the developer box printed before referring to, and at least once is used to the developer box printed and refer to the developer box 28 of mistake.That is to say that the developer roll of new reagent box never was activated in the past, and be once driving at least with the developer roll of the developer box of crossing.
As shown in Figure 7, box-like condition and type detector 120 comprise optical sensor 121 (example of detecting device), detection arm 122, turn 123 and controller 124.
Detect wall 122 and comprise cylindrical portion 122a, light intercepting arm 122b and contact arm 122c.Cylindrical portion 122a is inserted in the axle (not shown) of cabinet 2 settings, makes detection arm 122 to pivot.Light intercepting arm 122b and contact arm 122c are giving prominence to from cylindrical portion 122a on the direction separately with respect to the diametric(al) of cylindrical portion 122a.Detection arm 122 is configured to swing around cylindrical portion 122a.Turn 123 is installed to the correct position of the light intercepting arm 122b that detects wall 122.Thereby detection arm 122 is subjected to the effect of turn 123, so that be in the normal position all the time.When detection arm 122 is in the normal position, the end 122d of light intercepting arm 122b is in the light that illuminating part 121a and photographic department 121b position between the two intercept between the two and propagates, the end 122e of contact arm 122c be positioned this end 122e can with extension 92,102 position contacting that are installed to the developer box 28 on the cabinet 2.
The then action of engaging gear 80, rotary body 90 and detection arm 122 when in Fig. 8 A to Figure 12 D explanation cabinet 2 two kinds of dissimilar developer boxes 28 being installed.A new developer box 28 shown in Fig. 8 A to Fig. 9 B, Figure 12 A to Figure 12 D.
The action of engaging gear 80, rotary body 90 and detection arm 122 when the following describes the developer box 28 that 3000 consumptions will be installed in the cabinet 2.
Shown in Fig. 8 A, when developer box 28 was not installed in the cabinet 2, the extension 92 of the developer box 28 of 3000 consumptions was in the back-end location of elongated slot 73, and the 82a of tooth portion that has of engaging gear 80 is in the position that separates with transmission gear 67.Under this state, shown in Figure 10 A, the projection 91b of rotary body 90 is in first of engaging gear 80 and regulates rib 84 position adjacent.That is to say that first regulates the surface of the surperficial 84a of rib 84 towards the projection 91b of rotary body 90.
Next, when developer box 28 was inserted in the cabinet 2, extension 92 contacted and is pressed to gear with the work that always is subjected to turn 123 in order to the contact arm 122c that is positioned entopic detection arm 122.Shown in Fig. 8 B, when developer box 28 placed the box installation site of cabinet 2, the contact arm 122c of detection arm 122 was subjected to the acting force backward of extension 92, overcomes the acting force of turn 123.By this operation, detection arm 122 swings make the light intercepting arm 122b of detection arm 122 move forward.Because light intercepting arm 122b removes from this position, the light that illuminating part 121a is sent is received by photographic department 121b, and optical sensor 121 becomes conducting state and exports a predetermined Continuity signal and give controller 124.At this moment, the detection arm that is subjected to turn 123 effects has an opposition to be added on the extension 92, so that extension 92 moves forward shown in Figure 10 B.Extension 92 when back-end location is shifted to the place ahead, the extension 92 of pushing by contact arm 122c with contact wall 74a contact, contact wall 74a has a friction force to act on extension 92.
Shown in Figure 10 A and Figure 10 B, when extension 92 moves forward, first regulates the promotion forward that rib 84 is subjected to projection 91b, contact with the first surperficial 84a that regulates rib 84 by the projection 91b that makes rotary body 90, engaging gear 80 rotates a predetermined angle in the clockwise direction with rotary body 90.When engaging gear 80 rotated as mentioned above, the 82a of tooth portion that has of engaging gear 80 contacted and meshes with transmission gear 67.At this moment, shown in Figure 11 A and Figure 11 B, push the second first surface of contact 72b that supports the fitting piece 72a of axial region 72 by the sidewall of engaging groove 81a, engaging gear 80 is rotated toward interior promotion fitting piece 72a the time.
When controller 124 begins to dally, the driving force of drive unit 110 has a 82a of tooth portion by what input gear 62, neutral gear 65, stirrer-driven gear 66 and transmission gear 67 passed to engaging gear 80, thus engaging gear 80 rotation in the clockwise direction shown in Fig. 8 C.At this moment, shown in Figure 10 C, first regulates the front that rib 84 is positioned projection 91b, and extension 92 is because predetermined friction force effect and touch wall 74a engagement with separating, thereby first regulates that rib 84 moves forward and separate with projection 91b that the precalculated position is kept.Thereby, have only engaging gear 80 rotation in the clockwise direction shown in Fig. 8 C.Owing to can determine extension 92 and contact the acting force of wall 74a friction force between the two greater than contact arm 122c, does not move extension 92 when having only engaging gear 80 to move, shown in Fig. 8 C.Thereby detection arm 122 keeps current attitude, and optical sensor 121 continues to controller 124 output Continuity signals.
Then, shown in Figure 10 C, when engaging gear 80 further rotated with respect to rotary body 90, second regulates rib 85 shifted to projection 91b gradually.When the second adjusting rib 85 and projection 91b were engaged with each other, projection 91b was subjected to the promotion of the second adjusting rib 85, and rotary body 90 rotates with engaging gear 80 shown in Figure 10 D.When rotary body 90 rotated as mentioned above, extension 92 further moved forward and is disengaged with contact arm 122c, thereby detection arm 122 is back to the normal position under the acting force of turn 123.Thereby the light of detection arm 122 intercepting arm 122b also is back to its initial position, propagate with intercepting illuminating part 121a and photographic department 121b light between the two, thereby optical sensor 121 becomes and is in cut-off state, stops to controller 124 output Continuity signals.
After this, rotary body 90 is when further rotation and extension 92 arrive the front position of elongated slots 73 in the clockwise direction shown in Fig. 9 B, engaging gear 80 82a of tooth portion and transmission gear 67 throw out of gear are arranged, and the rotation of the body 90 that stops the rotation is shown in Figure 10 E.That is to say the unidirectional only rotation of rotary body 90.At this moment, shown in Figure 11 C, the engaging groove 81a of engaging gear 80 is back to its initial position, and engages once more with fitting piece 72a.Thereby, even if having one to be added on the engaging gear 80 at the acting force on the clockwise direction shown in Figure 11, the engaging groove 81a and the second surface of contact 72c also are engaged with each other, by be supported on the rotation that the fitting piece 72a that is out of shape on the sense of rotation of engaging gear 80 stops engaging gear 80 by supporting surface 72e.Thereby engaging gear 80 does not allow to mesh with transmission gear 67 once more.After this, controller 124 is finished idle running, and carries out box-like condition and type detection according to the duration that the Continuity signal that has or not optical sensor 121 to be provided and controller 124 receives Continuity signals.
The action of engaging gear 80, gear rotary body 100 and detection arm 122 when the following describes the developer box 28 that 6000 consumptions will be installed in cabinet 2.Action when the action of engaging gear 80, gear rotary body 100 and detection arm 122 is installed on the cabinet 2 with the developer box 28 of 3000 consumptions (engagement action that tooth portion 104 and transmission gear 67 are arranged of gear rotary body 100 and throw out of gear action) is identical, and its explanation is omitted.
Shown in Figure 12 A and Figure 12 B, when the developer box 28 of 6000 consumptions is installed on predetermined installation site in the cabinet 2, detection arm 122 is swung forward, and optical sensor 121 is exported to controller 124 with Continuity signal, and the situation that is installed on cabinet 2 with the developer box 28 of 3000 consumptions is same.
Then, controller 124 dallies.When controller 124 dallied, gear rotary body 100 is rotation in the clockwise direction immediately, and extension 102 moves forward shown in Figure 12 C.Therefore, detection arm 122 is disengaged with extension 102, and is back to the normal position under the acting force of turn 123.Thereby optical sensor 121 stops to export Continuity signal.That is to say that the duration that controller 124 receives Continuity signal is shorter than the situation that the developer box 28 of 3000 consumptions is installed on cabinet 2.
After this, gear rotary body 100 only carries out the rotation of single direction shown in Figure 12 D.Controller 124 is finished idle running then, and carries out box-like condition and type detection according to the duration that the Continuity signal that has or not optical sensor 121 to be provided and controller 124 receives Continuity signals.
Box-like condition and type detection then are described.At first explanation is configured to carry out the details of the controller 124 of box-like condition and type detection.As shown in FIG. 13A, controller 124 comprises ASIC(Application Specific Integrated Circuit) (ASIC) 201, ROM (read-only memory) (ROM) 202, random-access memory (ram) 203, nonvolatile ram (NVRAM) 204 and CPU (central processing unit) (CPU) 205.
Shown in Figure 13 B, when the extension traveling time was " α ", the box type was " 3000 consumptions ".When the extension traveling time was " β ", the box type was " 6000 consumptions ".
Temporary transient storage digital numerical value when RAM 203 is configured to carry out various program.NVRAM 204 is configured to store the photoreceptor signal input of no optical sensor 121 and the minute (with reference to Figure 14) that photoreceptor signal is imported.By carrying out the box-like condition of storing among the ROM202 and type detection program by CPU 205 and, carrying out box-like condition and type detection by ASIC 201 each unit of control.
With reference to Figure 14, Figure 15 A and Figure 15 B box-like condition and type detection are described.In the following describes, the developer box 28 of 3000 consumptions and the developer box 28 of 6000 consumptions also can be called low capacity developer box and high power capacity developer box.
Illustrate with new high power capacity developer box 28, new low capacity developer box 28 or with the developer box of crossing 28 below with reference to Figure 14 and to be installed in the cabinet 2 that optical sensor 121 its states change under each situation time of (conducting and by).
When new high power capacity developer box 28 is installed on the cabinet 2, as top with reference to Figure 12 A to Figure 12 D described, extension 102 contacts with detection arm 122, and the swing of optical sensor 121 by detection arm 122 becomes and be in conducting state (promptly beginning photoreceptor signal is input among the CPU 205).
Then, CPU 205 accessory drives 110 drive when dallying, extension 102 and detection arm 122 throw out of gear, and detection arm 122 is back to the normal position.Thereby optical sensor 121 becomes and is in cut-off state (promptly stopping photoreceptor signal being input among the CPU 205).
That is to say that when new high power capacity developer box 28 was installed on the cabinet 2, the extension traveling time was " β (second) ".
When new low capacity developer box 28 was installed on the cabinet 2, extension 92 contacted with detection arm 122.Thereby, as top with reference to Fig. 8 A and Fig. 8 B described, detection arm 122 is swung forward, optical sensor 121 becomes and is in conducting state.
Then, CPU 205 accessory drives 110 drive when dallying, and have only engaging gear 80 rotation predetermined amount of time, thereby extension 92 becomes and is in stationary state, and optical sensor 121 remains in conducting state.When the second projection 91b that regulates rib 85 and rotary body 90 of engaging gear 80 was engaged with each other, rotary body 90 was with engaging gear 80 rotations, and extension 92 is disengaged with detection arm 122.Thereby detection arm 122 is back to the normal position, and optical sensor 121 becomes and is in cut-off state.
Specifically, when new low capacity developer box 28 was installed on the cabinet 2, the extension traveling time was " α (second) ", and this time is longer than " β (second) " the extension traveling time when new high power capacity developer box 28 is installed.
With the developer box of crossing 28 (the high power capacity developer box of promptly using or with the low capacity developer box of mistake) when being installed on the cabinet 2, extension 92,102 is positioned the front end position (with reference to Fig. 9 B and Figure 12 D) in the elongated slot 73, thereby does not engage with detection arm 122.Thereby optical sensor 121 remains in cut-off state.
Letter shown in Figure 14 " X (second) " and " Y (second) " are the threshold values that will use in box-like condition and the type detection, and wherein letter " X " is for to be arranged at 0 second and the threshold value of β between second, and letter " Y " is then for being arranged at β second and the threshold value of α between second.
Below with reference to Figure 15 A and Figure 15 B box-like condition and the type detection that CPU 205 will carry out is described.
At first, whether whether the power supply that can determine laser printer 1 opened or had lid to close detection signal and input to CPU 205 (first step, below S represent step).When definite power supply do not open or not lid close detection signal and open/close detecting sensor 206 from protecgulum and input to CPU 205 (S1: in the time of not), flow process is back to main routine (not shown) and repeats the affirmation of S1.Determine laser printer 1 power supply opening or have lid to close detection signal when inputing to CPU 205 (S1: be), (S2) dallies.Among the S2, CPU 205 exports to a predetermined drive signal drive unit 110 and allows counter (not shown) minute, that is to say and measures the extension traveling time.Only when being in conducting state, optical sensor 121 just the extension traveling time is measured.
After the idle running beginning, determine just whether idle running finishes (S3).Definite idle running is not finished as yet, that is to say still (the S3: in the time of not), determine whether optical sensor 121 is in conducting state (being the positive input photoreceptor signal) (S4) that dallies.
When determining that optical sensor 121 is in conducting state (S4: be), whether flow process is back to S3 and finishes so that reaffirm idle running.(S4: in the time of not), CPU 205 permission counters stop the mensuration (S5) to the extension traveling time when definite optical sensor 121 is in cut-off state.After this, flow process is got back to S3.
When (S3:YES) finished in definite idle running, determine whether optical sensor 121 is in conducting state (S6).When definite optical sensor 121 was in conducting state (S6: be), although idle running is finished for instance, extension 92,102 and detection arm 122 still contacted with each other, so the extension traveling time is not carried out correct mensuration.Therefore, determining has mistake that (S7) takes place during box-like condition and the type detection, and flow process is back to main routine.When having mistake to take place during definite box-like condition and the type detection, can circulate a notice of the generation of mistake by the display on the guidance panel (not shown).
(S6: in the time of not), determine the extension traveling time has been carried out correct mensuration, less than threshold X (with reference to Figure 14) (S8) whether definite then extension traveling time value that is obtained when definite optical sensor 121 is in cut-off state.When the extension traveling time value of determining to be obtained during less than threshold X (S8: be), determine (S9) of developer box 28 that installed for using, flow process is got back to main routine.Determine the developer box 28 installed for used the time, CPU 205 is new for shifting out the number of printer paper that this developer box 28 is counted and stored in the middle of cabinet 2 from being defined as since the developer box of being installed 28, printer paper number is counted when printing whenever carrying out paper.
When definite extension traveling time value and when being not less than threshold X (S8: not), determine that whether extension traveling time value is less than threshold value Y (S10).When definite extension traveling time value during, determine that the extension traveling time is β second less than threshold value Y (S10: be).After this, with reference to the tables of data 208 of storage among the ROM 202, and are developer boxes (S11) of new 6000 consumptions according to the definite developer box of being installed 28 of the type in the tables of data 208 (i.e. 6000 consumptions) and extension traveling time (being β).Then, flow process turns back to main routine.When the developer box of determining to be installed 28 was the developer box of new 6000 consumptions, CPU 205 can use up information by guidance panel circular toner.That is to say that grate paper-arranaging sensor (not shown) has been installed after the developer box 28 has been detected 6000 paper when having formed image on it, CPU 205 will circulate a notice of toner and use up information.
When definite extension traveling time value is not that (S10: in the time of not), determine that extension traveling time value more than or equal to threshold value Y, that is to say, the extension traveling time is α second less than threshold value Y.After this, with reference to the tables of data 208 of storage among the ROM 202, and are developer boxes (S12) of new 3000 consumptions according to the definite developer box of being installed 28 of the type in the tables of data 208 (i.e. 3000 consumptions) and extension traveling time (being α).Then, flow process turns back to main routine.When the developer box of determining to be installed 28 was the developer box of new 3000 consumptions, CPU 205 can use up information by guidance panel circular toner.That is to say that grate paper-arranaging sensor (not shown) has been installed after the developer box 28 has been detected 3000 paper when having formed image on it, CPU 205 will circulate a notice of toner and use up information.
As mentioned above, when engaging gear 80 and rotary body 90 engaging gear 80 when first state becomes second state separates rotation with rotary body 90, even if thereby because of having caused undesired rotation power, misoperation of users passes to engaging gear 80 by gear mechanism 61, also can limit extension 92 motions.
But box-like condition and type detection successful execution, like this by being configured to can to comprise single or two parts from the kinematic train that transmission gear 67 passes to extension 92,102 revolving force, and correspondingly determine rotation start time of rotary body 90 and gear rotary body 100 according to the type of the developer box 28 that will use.In addition, the start time that move extension 92,102 differs from one another, but the displacement of extension 92,102 is identical.Therefore, do not need to increase the rotation amount (for example size of groove) of rotary body so that two contact protrusions are contacted with actuator as known developer box.Thereby, the size of developer box 28 is reduced to some extent.
The displacement of extension 92,102 can be set at long so that detect moving of extension 92,102 reliably by detecting device.The diameter of rotary body 90 also can be set at greatly to increase the displacement of extension 92.But the increase of rotary body 90 diameters can cause developer box 28 sizes to increase to some extent.As mentioned above, rotary body 90 and engaging gear 80 provide as the parts that separate, and rotary body 90 comprises the arm shape portion longer than the radius of engaging gear 80.Thereby, when being designed to than compactness, developer box 28 can guarantee that extension 92 has enough displacement.
When the developer box 28 with 3000 consumptions was installed on the cabinet 2, extension 92 was carried out relatively moving forward by contact arm 122c with respect to the developer box 28 of 3000 consumptions, engaging gear 80 have the 82a of tooth portion then with transmission gear 67 engagements.Utilize this structure, unless there is acting force to be added on the extension 92, when developer box 28 was not installed on the cabinet 2, the have 82a of tooth portion and the transmission gear 67 of engaging gear 80 were separated from each other.Therefore, even if the test period that the developer box of 3000 consumptions 28 its gears 62 to 67 carry out before shipment rotates through, engaging gear 80 and rotary body 90 can be with gear 62 to 67 rotations yet, thereby extension 92 can remain in suitable position, till developer box 28 is installed on the cabinet 2 first.
Second of lid member 70 support axial region 72 comprising fitting piece 72a be configured to keep anodontia the 82b (perhaps anodontia 105 of gear rotary body 100) of engaging gear 80 and this toward each other state of transmission gear 67 till having predetermined acting force to be added on the engaging gear 80.Utilize this structure, extension 92,102 can reliably remain in suitable position till developer box 28 is installed on the cabinet 2 first.
Second supports the supporting surface 72e that axial region 72 is included in engaging gear 80 support engages part 72a when pushing fitting piece 72a by the second surface of contact 72c.Utilize this structure, prevent the reverse rotation of engaging gear 80 by supporting surface 72e, thereby can reliably carry out the rotation of engaging gear 80 single directions.
The 82a of tooth portion is arranged and tooth portion 104 past internal strain on the diametric(al) of engaging gear 80 and gear rotary body 100 is respectively arranged.Utilize this structure, even if developer box 28 is to be installed to than hard intensity on the cabinet 2, engaging gear 80 or 100 rotations of gear rotary body, and the 82a of tooth portion is arranged or tooth portion 104 is arranged to strike than hard intensity on the transmission gear 67, also the impulsive force of collision can be absorbed.In addition, even if having the 82a of tooth portion, 104 end and transmission gear 67 to clash into each other, owing to having the 82a of tooth portion, 104 distortion to make the 82a of tooth portion, 104 end and transmission gear 67 slippage each other, thereby the 82a of tooth portion, 104 and transmission gear 67 positive engagement is each other arranged.
Under the state shown in Figure 10 B and Figure 10 C, contact wall 74a supports extension 92 with predetermined friction force, thereby detection arm 122 is kept on the position.
Though in conjunction with different structure example and demonstration mode explanation the present invention, to those skilled in the art, can under the situation that does not depart from the scope of the invention, carry out other distortion and modification to said structure example and demonstration mode at this.Consider that other structure and mode it will be apparent to those skilled in the art that to disclosed explanation of the present invention or practice here.What it is desirable to is, true scope of the present invention is by following claim definition, and instructions and illustrated each example are just schematically.
Adopt second of engaging gear 80 to regulate the example of the projection 91b of rib 85 and rotary body 90 as regulator.For instance, can change its transmission by type and recently adopt transmission gear 67, substitute in two types developer box 28 and all adopt gear rotary body 100 as regulator according to the developer box 28 that will use.
When as mentioned above, beginning to drive according to drive unit 110 and time (extension traveling time α or β) of experiencing between the two when becoming cut-off state of optical sensor 121 detect the type of the developer box of being installed 28.For instance, the drive amount of required between the two drive unit 110 when becoming cut-off state in the time of can beginning to drive according to drive unit 110 and as the optical sensor 121 that optical sensor 121 is detected detects the type of the developer box of being installed 28.In this case, for example this RPM of revolution number (rotations per minute) detecting sensor of motor of drive amount that a kind of known being configured to detect drive unit 110 can be set in drive unit 110, and controller 124 can be counted the revolution number during extension traveling time α or β.In this case, the extension traveling time α of the tables of data 208 shown in Figure 13 B or β can become the revolution of the motor of being counted and count R α and R β during extension traveling time α or β, can control according to the process flow diagram among Figure 17 A and Figure 17 B.In the process flow diagram among Figure 17 A and Figure 17 B, the extension traveling time among Figure 15 A and Figure 15 B becomes the revolution number of motor.Specifically, the process that will carry out of S2 ', S5 ', S8 ' and the S10 ' among Figure 17 A and Figure 17 B can be different with S2, S5, S8 and S10 among Figure 15 A and Figure 15 B.
S2 ' middle controller 124 begins to dally and to the counting of motor revolution number.S5 ' middle controller 124 stops the counting to motor revolution number.Determine among the S8 ' whether the motor revolution number of S2 ' and the actual acquisition of S5 ' time durations between the two counts RX less than the predetermined motor revolution that obtains during the threshold time X.Determine then among the S10 ' whether the motor revolution number of S2 ' and the actual acquisition of S5 ' time durations between the two counts RY less than the predetermined motor revolution that obtains during the threshold time Y.By carrying out S2 ', S5 ', S8 ' and S10 ' process, also can carry out gratifying box-like condition and type detection.
Carry out among Figure 15 A and Figure 15 B can between detection period, the accumulated value of 92,102 elapsed-time standards in mobile extension or the accumulated value of motor revolution number periodically being stored in the nonvolatile memory among the detection of extension traveling time or Figure 17 A and Figure 17 B during to the detection of motor revolution number.By carrying out like this, idle period laser printer 1 its power cut-off for example next time just can be with reference to the numerical value of being stored in the storer during laser printer 1 power-on.Thereby, can consider before laser printer 1 power remove that the action of engaging gear 80 and rotary body 90 carries out suitable control.
