As shown in Figure 1, identification means 10A is signal based on the light accepting part 11B from optical sensor 11 and the component identified the kind of Delevoping cartridge 28.Identification means 10A is a part for the control device 10 with CPU (central processing unit: CentralProcessing Unit), ROM (ROM (read-only memory): Read Only Memory) and RAM (random access memory: Random Access Memory) etc., realizes by carrying out the program prestored.
Control device 10 is configured to, when laser printer 1 starts, specifically, when to laser printer 1 input power, or not shown sensor is when detecting that front cover 2A closes, just driven to motor the stipulated time (being referred to as " initial actuating "), then carried out the identification maneuver of Delevoping cartridge 28 by identification means 10A.
Identification means 10A is configured to, based on representing from the light of light accepting part 11B acquired during initial actuating or the signal (light situation) of shading, and whether checking is consistent with the light situation of the Delevoping cartridge 28 prestored and identify Delevoping cartridge 28.Can by the time based on light or shading, and carry out specific according to the time span of continuous print light or shading to signal kinds, thus carry out the checking of this light situation.Such as, 0.1 ~ 0.2 second by light pulse signal symbolism be " A ", 0.2 ~ 0.3 second be subject to light pulse signal symbolism be (also identical for shading pulse signal) such as " B ".Further, by comparing the symbol rank and the symbol rank corresponding with the Delevoping cartridge 28 prestored that light situation signal acquired during initial actuating are given symbolism, thus identifiable design Delevoping cartridge 28.Or, can based on whether detecting that special symbol (situation of signal) identifies Delevoping cartridge 28.
For above-mentioned A type and Type B Delevoping cartridge 28, can according to or without slit 112 by the specified length that produces during detection faces LP by light pulse signal, and easily to identify.
< identification maneuver >
Now the identification maneuver of the Delevoping cartridge 28 in the laser printer 1 formed as above is described.
<<A type >>
First, be described with reference to the action of Fig. 4 and Fig. 6 to the situation that the new product Delevoping cartridge 28 of A type is arranged on main body cover 2.As shown in Fig. 4 (a), go forward Delevoping cartridge 28 is arranged on main body cover 2, detected portion 110, exports (the moment t0 Fig. 6) from optical sensor 11 from detection faces PL deflection rear side by light signal R0 because of the force of torsion spring 91.Now, motor stops (OFF).
When being opened by front cover 2A and being arranged on main body cover 2 by Delevoping cartridge 28 (t1), then as shown in Fig. 4 (b), the outer peripheral face 211 of rotary body 200A abuts with extension abutting part 120 and actuator 100 is positioned at neutral position.Now, because light shielding part 111 is positioned at detection faces PL, therefore, shielding signals S11 exports from optical sensor 11.In addition, in figure 6, the detailed change of signal when eliminating this installation.
When being closed by front cover 2A, then start initial actuating by control device 10.That is, start to drive (ON) motor (t2).Like this, rotary body 200A starts to rotate, and as shown in Fig. 4 (c), rotary body 200A is along being rotated counterclockwise in figure.Then, drive abutting part 220 to abut with the bearing surface 103A of actuator 100, and overcome the force of torsion spring 91 and actuator 100 is rotated clockwise (rotating forward).
At moment t3, when light shielding part 111 leaves from detection faces PL to front side, optical sensor 11 exports by light signal R11.Then, rotary body 200A along being rotated counterclockwise, and as shown in Fig. 4 (d), exports and should be subject to light signal R11, until drive abutting part 220 just to depart from bearing surface 103A.Then, as shown in Fig. 4 (e), when driving abutting part 220 departs from bearing surface 103A and actuator 100 rotates counterclockwise (reversion) because of the force of torsion spring 91 quickly, extend the end face 120A of abutting part 120 to abut with the outer peripheral face 211 of rotary body 200A, actuator 100 turns back to neutral position.Therefore, because light shielding part 111 is positioned at detection faces PL, therefore export shielding signals S12 (t6).
Then, rotary body 200A is along being rotated counterclockwise, until the toothless portion) 202 of rotary body 200A is relative with stirrer-driven gear 66, rotary body 200A stops (t20) with the posture shown in Fig. 4 (f).Then, control device 10 makes motor stop and terminating initial actuating.During from moment t6 to moment t20, because the extension abutting part 120 of actuator 100 continues to abut with the outer peripheral face 211 of rotary body 200A, therefore, the posture of actuator 100 does not change, and continue to export shielding signals S12, motor continues after stopping to export shielding signals S12 too.Identification means 10A based on the shielding signals S11 obtained during this initial actuating, S12 and by light signal R11, and based on do not detect the short time corresponding with slit 112 by light signal, and to identify Delevoping cartridge 28 are A types in A type and Type B.In addition, during initial actuating, based on detecting by light signal R11, and judge that Delevoping cartridge 28 is new products.
In addition, when Delevoping cartridge 28 is non-installations, then detect by light signal R0 by optical sensor 11, when Delevoping cartridge 28 is installations, after initial actuating terminates, owing to detecting shielding signals S12, therefore, identification means 10A can judge the installation of Delevoping cartridge 28 after initial actuating terminates based on detecting shielding signals.On the contrary, identification means 10A, when detecting after initial actuating terminates by light signal, can judge the non-installation of Delevoping cartridge 28.
<<B type >>
Below, with reference to Fig. 5 and Fig. 6, the action new product Delevoping cartridge 28 of Type B being arranged on situation on main body cover 2 is described.As shown in Fig. 5 (a), go forward Delevoping cartridge 28 is arranged on main body cover 2, detected portion 110, exports (t0) from optical sensor 11 from detection faces PL deflection rear side by light signal R0 because of the force of torsion spring 91.Now, motor stops.
When being opened by front cover 2A and being arranged on main body cover 2 by Delevoping cartridge 28 (t1), then as shown in Fig. 5 (b), the outer peripheral face 211 of rotary body 200B abuts with extension abutting part 120 and actuator 100 is positioned at neutral position.Now, because light shielding part 111 is positioned at detection faces PL, therefore, shielding signals S21 exports from optical sensor 11.
When being closed by front cover 2A, then start initial actuating by control device 10.That is, drive motor (t2) is started.Like this, rotary body 200B starts to rotate, and as shown in Fig. 5 (c), shielding signals S11 continues to export until extend abutting part 120 just entered accommodation section 230 from optical sensor 11.Then, when extending abutting part 120 and departing from outer peripheral face 211, actuator 100 reverses because of the force of torsion spring 91, extend abutting part 120 and enter accommodation section 230, and as shown in Fig. 5 (d), actuator 100 rotates until abut with inwall 230A.Now, because the slit 112 of detected portion 110 and the light shielding part 111 of front side are to pass through detection faces PL at a high speed, therefore, what optical sensor output stage was short is subject to light signal R21 and shielding signals S22, then exports by light signal R22.Also can be used for identifying Delevoping cartridge 28 by light signal R21 and shielding signals S22, but due to pickup electrode short, therefore preferably do not use, to prevent from identifying by mistake.
Then, when rotary body 200B is along when being rotated counterclockwise, then inwall 230A presses and extends abutting part 120, thus actuator 100 overcomes the force of torsion spring 91 and rotates forward.As shown in Fig. 5 (e), when detected portion 110 enters between the illuminating part 11A of optical sensor 11 and light accepting part 11B, then at moment t4, the light shielding part 111 of front side exports shorter shielding signals S23 by detection faces PL, then, slit 112 exports shorter in light signal R23 by detection faces PL.In addition, when rotary body 200B is along when being rotated counterclockwise, then the light shielding part 111 of rear side is positioned at detection faces PL and exports shielding signals S24 (t6).
Further, rotary body 200B continues to rotate, and when extending abutting part 120 and being outer to accommodation section 230, the end face 120A extending abutting part 120 just abuts with the outer peripheral face 211 of rotary body 200B, and actuator 100 turns back to neutral position.
Then, rotary body 200B is along being rotated counterclockwise until the toothless portion) 202 of rotary body 200B is relative with stirrer-driven gear 66, and rotary body 200B stops (t20) with the posture shown in Fig. 5 (f).Then, control device 10 makes motor stop and terminating initial actuating.During from moment t6 to moment t20, because the extension abutting part 120 of actuator 100 continues to abut with the outer peripheral face 211 of rotary body 200B, therefore, the posture of actuator 100 does not change, continue to export shielding signals S24, motor continues after stopping to export shielding signals S24 too.Identification means 10 based on the shielding signals S21 obtained during this initial actuating, S23, S24 and by light signal R22, R23, and based on detect the short time corresponding with slit 112 by light signal R23, and identify that Delevoping cartridge 28 is the A types in A type and Type B.In addition, during initial actuating, based on detecting by light signal R22, R23, and judge that Delevoping cartridge 28 is new products.
In addition, for the installation of Delevoping cartridge 28, the judgement of non-installation, identical with the situation of A type.
As described above, adopt the laser printer 1 of the 1st embodiment, the situation of A type Delevoping cartridge 28 is being installed and the situation of Type B Delevoping cartridge 28 has been installed, because the rotation direction of actuator 100 is contrary, therefore, just utilize optical sensor 11 to detect another part (part rotation direction is tossed about mutually) of detected portion 110.Further, when the outer peripheral face 211 of rotary body 200 abuts with actuator 100, be set to benchmark with detecting position and be configured to asymmetric in the rotation direction of actuator 100, thus, the Delevoping cartridge 28 of identifiable design A type and Type B.That is, the direction of rotating according to actuator 100 due to the output signal of optical sensor 11 and different, therefore, it is possible to utilize the difference of the rotation direction of actuator 100, and does not identify the box of multiple types with not increasing parts count.
In addition, laser printer 1, owing to arranging slit 112 in its detected portion 110, and this slit 112 is set to benchmark with detecting position and is only configured in the side of the rotation direction of actuator 100, therefore, the output signal of the optical sensor 11 that box kind produces is obviously different, easily identifies box.Especially the laser printer 1 of the 1st embodiment, due at neutral position slit 112 with detection faces PL for benchmark is only configured in a side side of rotation direction, therefore, whether judged the rotation direction of actuator 100 by slit 112 by detection faces PL, thus easily box is identified.
Above, in the laser printer 1 of the 1st embodiment, the situation that two kinds of Delevoping cartridges 28 of A type and Type B identify is described, but the Fig. 7 for laser printer 1 represents that the C type Delevoping cartridge 28 of an example another as the 1st box of action or Fig. 8 represent the C type Delevoping cartridge 28 of the another example as the 2nd box of action, also can identify.Therefore, below, the action of the situation that main body cover 2 is provided with C type and D type Delevoping cartridge 28 is described.
<<C type >>
For the action of situation of new product Delevoping cartridge 28 of having installed C type, illustrate with reference to Fig. 7 and Fig. 9.Fig. 7 represents that the new product Delevoping cartridge 28 by C type is arranged on the action of the situation on main body cover 2.As shown in Fig. 7 (b), the rotary body 200C of C type Delevoping cartridge 28 is provided with two at the left surface of rotary body 200C and drives abutting part 220, drive abutting part 220 to depart from predetermined angular configuration by two, to make, during rotary body 200C rotates predetermined angular (being less than rotation once), to make actuator 100 swing secondary by each driving abutting part 220.
According to this structure, then because first drives the driving abutting part 220 identically generation effect of abutting part 220 and A type Delevoping cartridge 28, therefore, the action of the actuator 100 of Fig. 7 (a) to (e) is identical with Fig. 4 (a) to (e), therefore, optical sensor 11 signal of the C type of Fig. 9 is also identical with optical sensor 11 signal of the A type of Fig. 6 to moment t6.And, as shown in Fig. 7 (e), after first drives abutting part 220 to depart from extension abutting part 120 and actuator 100 is in neutral condition, rotary body 200C just along further rotate counterclockwise and second drive abutting part 220 (for simplicity, represent with profile line in Fig. 7) abut with the bearing surface 103A of actuator 100, when making actuator 100 rotate forward, then as shown in Fig. 7 (f), light shielding part 111 departs from detection faces PL and exports by light signal R12 (t7) from optical sensor 11.Then, repeat and first effect driving the effect of abutting part 220 identical, turn back to neutral position at moment t10 actuator 100, then, continue to export shielding signals S13 from optical sensor 11.
As above, when driving abutting part 220 to be two, identification means 10A is based on the shielding signals S11 obtained during this initial actuating, S12, S13 and be subject to light signal R11, R12, and is identified as the C type Delevoping cartridge 28 of the A type that is different from, Type B and D type.Specifically, based on detecting by light signal R11, R12 bis-times and not detecting being subject to light signal of the short time corresponding with slit 112 and be identified as C type Delevoping cartridge 28.In addition, during initial actuating, judge that Delevoping cartridge 28 is new products based on detecting by light signal R11, R12.
In addition, for the installation of Delevoping cartridge 28, the judgement of non-installation, identical with the situation of A type.
<<D type >>
With reference to Fig. 8 and Fig. 9, the action of situation of the new product Delevoping cartridge 28 being provided with D type is described.Fig. 8 represents the action of the situation of the new product Delevoping cartridge 28 being provided with D type on main body cover 2.As shown in Fig. 8 (b), the rotary body 200D of D type Delevoping cartridge 28 is provided with two accommodation sections 230 at the left surface of rotary body 200D, two accommodation sections 230 are departed from predetermined angular configuration, to make, during rotary body 200D rotates predetermined angular (being less than rotation once), to make actuator 100 swing secondary by each accommodation section 230.
According to this structure, due to first accommodation section 230 and the accommodation section 230 identically generation effect of Type B Delevoping cartridge 28, therefore, the action of the actuator 100 of Fig. 8 (a) to (e) is identical with Fig. 5 (a) to (e), therefore, optical sensor 11 signal of the D type of Fig. 9 is also identical with optical sensor 11 signal of the Type B of Fig. 6 to moment t6.Further, after the state of such as Fig. 8 (e), when rotary body 200D along be rotated counterclockwise and the extension abutting part 120 of actuator 100 leaves first accommodation section 230 time, actuator 100 forms neutral condition (t6 ~ t7).And, as shown in Fig. 8 (f), when rotary body 200C enters second accommodation section 230 (for simplicity along further rotating counterclockwise, represent with profile line in Fig. 8) time, then second accommodation section 230 produces effect identically with first accommodation section 230, and exports the signal identical with moment t3 ~ t6 at t7 ~ t10.After moment t10, actuator 100 turns back to neutral position, then, continues to export shielding signals S27 from optical sensor 11.
As above, when accommodation section 230 is two, identification means 10A is based on the shielding signals S21 obtained during this initial actuating, S23, S24, S26, S27 and be subject to light signal R22, R23, S25, S26, and based on detect the short time that secondary is corresponding with slit 112 by light signal R23, R26, and identify the D type Delevoping cartridge 28 of the A type that is different from, Type B and C type.In addition, during initial actuating, based on detecting by light signal R22, R23, R25, R26, and judge that Delevoping cartridge 28 is new products.
In addition, for the installation of Delevoping cartridge 28, the judgement of non-installation, identical with the situation of A type.
<<E type, F type >>
In the laser printer 1 of the 1st embodiment, sometimes also identify the Delevoping cartridge 28 having and drive abutting part 220 and 230 liang of sides, accommodation section.Namely, as shown in Figure 10 (a), due to after driving abutting part 220 generation effect, according to be configured to accommodation section 230 generation effect, the E type Delevoping cartridge 28 that have employed rotary body 200E, thus optical sensor 11 exports the signal corresponding with driving abutting part 220 and accommodation section 230 in order, therefore, identifiable design is for being E type Delevoping cartridge 28.In addition, as shown in Figure 10 (b), due to after the generation effect of accommodation section 230, according to being configured to F type Delevoping cartridge 28 that drive abutting part 220 generation effect, that have employed rotary body 200F, thus optical sensor 11 exports the signal corresponding with driving abutting part 220 and accommodation section 230 in order, therefore, identifiable design is for being F type Delevoping cartridge 28.So, drive abutting part 220 and 230 liang, accommodation section side if arrange on the rotary body 200 of a Delevoping cartridge 28, then by the action of actuator 100 change variation, thus can increase the kind of discernible box 28.
In addition, if other box type of optionally installing is the 1st box, then E type and F type Delevoping cartridge 28 can be considered the 2nd box, if the type of other box optionally installed is the 2nd box, then E type and F type Delevoping cartridge 28 can be considered the 1st box.
[the 2nd embodiment]
Below, be described with reference to the laser printer 1 of Figure 11 and Figure 12 to the 2nd embodiment.The laser printer 1 of the 2nd embodiment, because the shape of the only detected portion 110B of its actuator 100 is different from the 1st embodiment, therefore, is only described different piece.In addition, for functionally identical with the 1st embodiment part, figure puts on identical symbol.
As shown in Figure 11 (a), the detected portion 110B of the actuator 100B of the laser printer 1 of the 2nd embodiment, when neutral position, is formed with two slits 112 at the rear side of detection faces PL, is formed with a slit 112 in front side.The part except slit 112 of detected portion 110B is light shielding part 111.In addition, Figure 11 (a) represents state when having installed the new product Delevoping cartridge 28 of A type, and Figure 11 (b) represents state when having installed the new product Delevoping cartridge 28 of Type B.

On the other hand, when the new product Delevoping cartridge 28 installing Type B on main body cover 2 and when being closed by front cover 2A, signal as shown in Figure 12 can be obtained from optical sensor 11.As shown in optical sensor 11 signal of the Type B of Figure 12, when installing Type B Delevoping cartridge 28, just becoming the neutral position shown in Figure 11 (b) and exporting shielding signals S41.Then, when initial actuating starts, accommodation section 230 just holds actuator 100, during moment t3 ~ t4, export by light signal R41, then, exports corresponding with a slit 112 of front side one and shorter be subject to light signal R42 ((t5 ~ t6).After actuator 100 departs from accommodation section 230, just turn back to neutral position, and export shielding signals S43.
As described above, when having installed the new product Delevoping cartridge 28 of A type, detect shorter by light signal R31, R32 corresponding with two slits 112 of secondary, on the other hand, when having installed the new product Delevoping cartridge 28 of Type B, detect once corresponding with slit 112 shorter in light signal R42.So, according to the laser printer 1 of the 2nd embodiment, by corresponding with slit 112 shorter in light signal, A type Delevoping cartridge 28 or Type B Delevoping cartridge 28 can be identified.In addition, whether be the installation of new product and Delevoping cartridge 28, the judgement of non-installation for Delevoping cartridge 28, can carry out identically with the 1st embodiment.
[the 3rd embodiment]
Below, be described with reference to the laser printer 1 of Figure 13 and Figure 14 to the 3rd embodiment.The laser printer 1 of the 3rd embodiment, because the shape of the only detected portion 110C of its actuator 100 is different from the 1st embodiment, therefore, only illustrates different piece.In addition, for functionally identical with the 1st embodiment part, figure puts on identical symbol.
As shown in Figure 13 (a), the detected portion 110C of the actuator 100C of the laser printer 1 of the 3rd embodiment, is not formed with slit 112.Replace, when neutral position, by making the length of the detection faces PL front part of light shielding part 111 and rear section extremely different, thus detected portion 110 with detection faces PL for benchmark and become asymmetric in the rotation direction of actuator 100C.In addition, Figure 13 (a) represents state when being provided with the new product Delevoping cartridge 28 of A type, and Figure 13 (b) represents the state being provided with the new product Delevoping cartridge 28 of Type B.
In the laser printer 1 of this structure, when the new product Delevoping cartridge 28 installing A type on main body cover 2 and when being closed by front cover 2A, just can obtain signal as shown in Figure 14 from optical sensor 11.As shown in optical sensor 11 signal of the A type of Figure 14, when installing A type Delevoping cartridge 28, just become the neutral position shown in Figure 13 (a) and export shielding signals S51, then, when initial actuating starts, drive abutting part 220 that actuator 100 is rotated forward, between the longer-term to moment t5, continue to export shielding signals S51.Then, at moment t5 ~ t6 comparatively between short-term, because light shielding part 111 is from detection faces PL deflection front side, therefore, export by light signal R51, at moment t6, when driving abutting part 220 to depart from actuator 100, actuator 100 turns back to neutral position due to the force of torsion spring 91 quickly, and exports shielding signals S52.
On the other hand, when the new product Delevoping cartridge 28 installing Type B on main body cover 2 and when being closed by front cover 2A, signal as shown in Figure 14 can be obtained from optical sensor 11.As shown in optical sensor 11 signal of the Type B of Figure 14, when installing Type B Delevoping cartridge 28, becoming the neutral position shown in Figure 13 (b) and exporting shielding signals S61, and, when initial actuating starts, accommodation section 230 holds actuator 100, during moment t3 ~ t4, exports by light signal R61, then, when actuator 100 departs from accommodation section 230, just turn back to neutral position, export shielding signals S62.
As described above, when having installed the new product Delevoping cartridge 28 of A type, longer shielding signals S51 and the shorter combination by light signal R51 can be detected, and (moment t2 ~ t3) shorter shielding signals S61 and the longer combination by light signal R61 when having installed the new product Delevoping cartridge 28 of Type B, can be detected.So, according to the laser printer 1 of the 3rd embodiment, also by shielding signals and the difference in length by light signal, identify A type Delevoping cartridge 28 or Type B Delevoping cartridge 28.In addition, whether be the installation of new product and Delevoping cartridge 28, the judgement of non-installation for Delevoping cartridge 28, can carry out identically with the 1st embodiment.
[the 4th embodiment]
Below, be described with reference to the laser printer 1 of Figure 15 and Figure 16 to the 4th embodiment.The laser printer 1 of the 4th embodiment, because the shape of the only detected portion 110D of its actuator 100D is different from the 1st embodiment, therefore, only illustrates different piece.In addition, for functionally identical with the 1st embodiment part, figure puts on identical symbol.
As shown in Figure 15 (a), the detected portion 110D of the actuator 100D of the laser printer 1 of the 4th embodiment, when not being provided with Delevoping cartridge 28, light shielding part 111 is in detection faces PL, is interdicted by the light of optical sensor 11.Further, as shown in Figure 15 (b), the neutral position of Delevoping cartridge 28 being installed, by slit 112 being configured in the position of detection faces PL, thus the light of optical sensor 11 being passed through.In addition, when neutral position, be configured with a slit 112 in the front side of detection faces PL, be not configured with slit 112 at rear side.So, by slit 112, detected portion 110 becomes asymmetric with detection faces PL for benchmark in the rotation direction of actuator 100D.In addition, Figure 15 (b) represents the state of having installed the new product Delevoping cartridge 28 of A type, and Figure 15 (c) represents the state of having installed the new product Delevoping cartridge 28 of Type B.
In the laser printer 1 of this structure, when the new product Delevoping cartridge 28 installing A type on main body cover 2 and when being closed by front cover 2A, just can obtain signal as shown in Figure 16 from optical sensor 11.As shown in optical sensor 11 signal of the A type of Figure 16, when before installation A type Delevoping cartridge 28, as shown in Figure 15 (a), because light shielding part 111 is positioned at detection faces PL, therefore, export shielding signals S0 from optical sensor 11.On the other hand, when installing Delevoping cartridge 28, just becoming the neutral position shown in Figure 15 (b) and exporting by light signal R71.Further, when initial actuating starts, abutting part 220 is driven actuator 100 to be rotated forward, during moment t2 ~ t3, export shielding signals S71, then, during moment t3 ~ t6, because light shielding part 111 is from detection faces PL deflection front side, therefore, export by light signal R72.Further, at moment t6, when driving abutting part 220 to depart from actuator 100, actuator 100 turns back to neutral position due to the force of torsion spring 91 quickly, now, after exporting shielding signals S72 instantaneously, exports by light signal R73 in neutral position.
On the other hand, when the new product Delevoping cartridge 28 installing Type B on main body cover 2 and when being closed by front cover 2A, signal as shown in Figure 16 can be obtained from optical sensor 11.As shown in optical sensor 11 signal of the Type B of Figure 16, before installation Type B Delevoping cartridge 28, as shown in Figure 15 (a), because light shielding part 111 is positioned at detection faces PL, therefore, export shielding signals S0 from optical sensor 11.On the other hand, when installing Delevoping cartridge 28, just becoming the neutral position shown in Figure 15 (c) and exporting by light signal R81.Further, when initial actuating starts, accommodation section 230 just holds actuator 100, during moment t2 ~ t4, exports shielding signals S81.Further, when actuator 100 is received the inwall 230A pressing in portion 230 and rotates forward, then slit 112 is by detection faces PL, exports by light signal R82 thus, and in addition, shorter light shielding part 111 passes through and exports shielding signals S82.When extend abutting part 120 from accommodation section 230 to outside and actuator turns back to neutral position time, just export by light signal R83.
