Description
Technical Field
The invention relates to a detection method of a processing box and the processing box.
Background
In the related art, a process cartridge is detachably mounted on an electronic image forming apparatus. The electronic imaging device is internally provided with a driving head for outputting a rotary driving force. The process cartridge generally includes a driving assembly receiving a rotational force, a developing unit, a developer, a powder control unit, and a casing accommodating the above units, and additionally, a photosensitive unit, a charging unit, a cleaning unit, an agitating unit, and the like are additionally provided according to various kinds of process cartridge structures. The driving assembly of the processing box is arranged at one end of the processing box along the axial direction of the developing unit or the photosensitive unit, and after the driving assembly is meshed with a driving head in the electronic imaging device, the driving assembly transmits the rotating driving force to the processing box, and finally, the rotating unit (such as the developing unit, the photosensitive unit, the stirring unit and the like) in the processing box is driven to rotate to participate in the developing operation (namely, the printing operation) of the electronic imaging device.
Since the developer in the process cartridge is consumed along with the development of the process cartridge in the electrophotographic apparatus, the remaining amount of the developer in the process cartridge needs to be detected by a detection mechanism in the electrophotographic apparatus in order to detect the remaining amount of the developer in the process cartridge.
As shown in fig. 1, which is a side sectional view of the process cartridge b, the developer accommodating chamber b150 of the developing chamber b100 of the process cartridge b accommodates the developer, the upper surface of the developing chamber b100 is provided with an upper translucent member b1a and an incident surface b1a1, the bottom surface of the developing chamber b100 is provided with a lower translucent member b2a and an exit surface b2a1, and the upper translucent member b1a and the lower translucent member b2a are correspondingly disposed at the height of the developing chamber b 100. The electronic imaging device is provided with a light emitting element LS101 (e.g., a light emitting portion of a Light Emitting Diode (LED)) corresponding to the incident surface b1a1, and a light receiving element LS102 corresponding to the exit surface b2a 1. When the process cartridge b is mounted in the electronic image forming apparatus, the light emitting element LS101 reflects the sensing light to the lower translucent element b2a at the bottom of the developing hopper b100 by emitting the sensing light to the incident surface b1a1 of the upper translucent element b1a and guiding the same to the reflection surface, and finally outputs the sensing light to the outside from the exit surface b2a1 by reflection and is received by the light receiving element LS 102. Here, the electronic imaging device is also provided with a detection device which is connected with the light emitting element LS101 and the light receiving element LS102, the detection device detects and judges the detection light received by the light receiving element LS102, and if the light intensity or the illumination time of the detection light does not reach a preset value, the processing box b is judged to have the developer left; if the light intensity or the light irradiation time of the detection light reaches a preset value, it is determined that the developer in the process cartridge b has been consumed and a user is prompted to replenish the developer or replace the process cartridge.
However, there is currently a new type of electronic imaging device in which the process cartridge is inspected using two sets of light detectors (two pairs of light emitting elements and light receiving elements) to determine whether the process cartridge mounted by the user is the preset target process cartridge, and the existing process cartridge having only one set of light transmitting elements (upper light transmitting element and lower light transmitting element) has not been adaptable to the new type of electronic imaging device.

(detection Process of electronic imaging device)
As shown in fig. 7 to 9, in order to detect and recognize the process cartridge b in the electrophotographic apparatus P, when a certain amount of developer is present in the developer accommodating chamber b150 of the process cartridge b, the electrophotographic apparatus P indicates that the process cartridge b is ready to be mounted for a developing job by light detection of the process cartridge b. The light detection process comprises the following steps:
the first optical detection process: the first light emitting element LS101 emits the detection light to the incident surface b31 to guide the detection light into the first light transmitting element b30, the detection light is reflected to the reflection surface corresponding to the exit surface b32 through the reflection surface corresponding to the incident surface b31, the reflection light is reflected for 2 times, and then the detection light is emitted outwards through the exit surface b32 and received by the first light receiving element LS 102; a set of light detection in the electronic imaging device P is completed.
And a second optical detection process: the second light emitting element LS201 emits the detection light to the incident surface b41 to guide the detection light into the second light transmitting element b40, the detection light is reflected to the reflection surface corresponding to the exit surface b42 through the reflection surface corresponding to the incident surface b41, the reflection light is reflected for 2 times, and then the detection light is emitted to the outside through the exit surface b42 and received by the second light receiving element LS 202; another set of photo-detection in the electronic imaging device P is completed.
And (3) a light detection process is carried out: the completion of the above-mentioned photodetection processes one and two indicates that the process cartridge b in the electronic imaging device P is the target process cartridge of the electronic imaging device P, and the failure to complete one of the photodetection processes one and two indicates that the process cartridge is not suitable for the electronic imaging device. Therefore, the electronic image forming apparatus P needs to perform not only the above-described photodetection processes one and two but also the detection of the presence or absence of the developer in the process cartridge b by the light transmission detection between the first light emitting element LS101 and the second light receiving element LS 202. The detection light passes through the reflection surface b33 guided to the other end of the first translucent member b30 after being emitted by the first light emitting element LS101 to the incident surface b31, the reflection surface b33 reflects the detection light to the reflection surface b43 of the second translucent member b40 located at the bottom of the process cartridge b corresponding to the height of the process cartridge b, the reflection surface b43 reflects the detection light and emits the light outward through the exit surface b42, and finally the detection light is received by the second light receiving element LS 202. Here, since the path of light reflection will pass through the developer accommodating chamber b150 of the process cartridge b, there are three cases in the photodetection process three:
(1) when a certain amount of developer remains in the developer accommodating chamber b150 of the process cartridge b, the developer in the developer accommodating chamber b150 completely covers the second translucent member b40 located at the bottom of the process cartridge b, and therefore the detection light emitted from the first light-emitting element LS101 guided by the first translucent member b30 will not be irradiated onto the second translucent member b 40. At this time, the electrophotographic apparatus P indicates that the detection of the target process cartridge is completed, and normal development work can be performed. That is, the second light receiving element LS202 detects that the detection light emitted from the first light emitting element LS101 does not reach the preset light intensity or the illumination time does not reach the preset value of the detecting device PD2, as shown in fig. 7.
(2) When a small amount of developer remains in the developer accommodating chamber b150 of the process cartridge b but the electrophotographic apparatus P determines that the preset development quality of the developing operation of the process cartridge b can be achieved, although the detection light guided by the first translucent member b30 can be irradiated onto the second translucent member b40 and guided to be finally received by the second light receiving member LS202, since the light intensity or the light irradiation time of the detection light does not reach the preset value of the detection apparatus PD2, the electrophotographic apparatus P can also display that the detection of the target process cartridge is completed and a normal developing operation can be performed, but does not immediately display that the detection identification of the process cartridge b is not completed and a normal developing operation cannot be performed as long as the detection light is received by the second translucent member b40, as shown in fig. 8.
(3) When there is no developer in the process cartridge b at all or the remaining developer fails to reach the preset development quality of the process cartridge b judged by the electrophotographic apparatus P, the light intensity or light irradiation time of the detection light received by the second light receiving element LS202 reaches the preset value, and therefore the electrophotographic apparatus P can also indicate that the target process cartridge is not detected and identified to be completed and the development job cannot be performed, as shown in fig. 9.
(light inspection of Process Cartridge and information feedback of Process Cartridge chip)
As shown in fig. 2 and 6, the photosensitive member a is further provided with a chip 830 at one end thereof, the chip 830 contacts with a chip contact unit PD2a in the electronic imaging device P to record the information about the process cartridge b into the chip 830, and the chip contact unit in the subsequent electronic imaging device P again contacts with the chip 830 to read and acquire the information about the process cartridge b. The light detection process of the processing box and the information writing process of the chip of the processing box are as follows:
(1) when the developing hopper b100 of the process cartridge b is empty of developer, and the light intensity or light irradiation time of the detection light received by the second light receiving element LS202 from the first light emitting element LS101 is maximum (maximum current value is present), the detection device PD2 records the information of "no developer is present" in the chip 830 through the chip contact unit PD2a, and the detection device determines that the process cartridge b cannot perform the developing operation.
(2) When the developing hopper b100 of the process cartridge b has a sufficient amount of developer, and the second light receiving element LS202 does not detect the detection light (no current value) of the first light emitting element LS101 at all, the detecting means PD2 records the information of "sufficient developer is still present" in the chip 830 through the chip contact unit PD2a, and the detecting means judges that the process cartridge can perform the developing operation.
(3) When 10% to 20% of the developer remains in the developing hopper b100 of the process cartridge b, the second light receiving element LS202 receives the detection light of the first light emitting element LS101 reaching a preset first threshold value (a set first current value), the detecting device PD2 records the information of "low amount of developer" in the chip 830 through the chip contact unit PD2a, and the detecting device further continues to determine that the process cartridge can perform the developing operation.
(4) When 2% to 10% of the developer remains in the developing hopper b100 of the process cartridge b, the second light receiving element LS202 receives that the detection light of the first light emitting element LS101 reaches a preset second threshold value (a set second current value), the detection device PD2 records the information of the "number of printable pages remaining" and the "replenishment developer or replacement process cartridge or replacement developer carrier hopper" in the chip 830 through the chip contact unit PD2a, and the detection device further continues to determine that the process cartridge can perform the developing operation.
Through the light detection process and the real-time chip information feedback process, the developer consumption of the processing box b can be monitored at any time and fed back in time, so that the waste of residual developer is avoided.
(developing detection method of Process Cartridge)
Since the process cartridge b needs to go through the inspection recognition process of the electronic image forming apparatus P in the inspection process of the electronic image forming apparatus as described above, the developing job (printing) can be performed. Since the process cartridge b is independently separated from the developer carrier cartridge b200, the process cartridge b does not have developer therein before the developer carrier cartridge b200 is mounted to the process cartridge b. Therefore, the process cartridge b and the developer carrier chamber b200 can be individually packaged and well preserved before use, and key components (such as the developing unit 30, the powder control unit 50 and other components cooperating with the developing operation) in the process cartridge b are not polluted by the developer or cause poor quality of the developer during long-term storage or transportation before use.
Here, before the process cartridge b is used, it is also necessary to perform a developing work test (i.e., "print" check) on the process cartridge b to determine whether the developing quality of the process cartridge b meets a predetermined standard, and if the developing quality of the process cartridge b does not meet the standard, a repair work is required on the process cartridge b. However, since the process cartridge b has no developer therein, the process cartridge b will not be detected and recognized as shown in fig. 9 directly after the process cartridge b is mounted to the electrophotographic apparatus P. The operator needs to simulate the presence of the developer in the process cartridge b or to make the light intensity or the light irradiation time of the detection light received by the second light receiving element LS202 from the exit surface b42 of the process cartridge b less than the preset value of the detection device PD2 of the electronic image forming device P in order to detect and recognize that the developer is not present in the process cartridge b by the electronic image forming device P.
The first developing detection method of the processing box comprises the following steps:
in the first developing detection method, as shown in fig. 10 to 13, the second light-transmitting element b40 (which may be the first light-transmitting element b 30) at the bottom of the developing chamber b100 is provided as two separate parts, the incident surface b41 and the exit surface b42 are provided as the first part b40a of the second light-transmitting element b40, the reflective surface b43 is provided as the second part b40b of the second light-transmitting element b40, the first part b40a is placed on the card slot b102 at the bottom of the developing chamber b100, the second part b40b is correspondingly inserted into the positioning hole b101 adjacent to the card slot b102, and the second part b40b can rotate for a certain time after being inserted into the positioning hole b 101.
(1) Before the process cartridge b is mounted to the electrophotographic apparatus P and development detection is performed, a layer of developer is coated on the developing unit 30 of the process cartridge b; the coating amount of the developer is preferably 1 to 5 g, and only the development detection is required, and the development of characters or patterns on paper can be realized by 1 to 5 g of the developer.
(2) Before the process cartridge b is mounted to the electronic image forming apparatus P, the second block b40b is rotated so that the reflective surface b43 of the second block b40b is not aligned with the first block b40 a. In this way, after the process cartridge b is mounted to the electronic image forming apparatus P, the process cartridge b can complete the above-described first photo process and second photo process (the inspection process of the electronic image forming apparatus), while in the third photo process, due to the rotation of the second member b40b, the detection light emitted from the first light emitting element LS101 will not be correctly reflected onto the second light receiving element LS202 by the reflection surface b43 because the reflection surface b43 is not aligned with the first member b40a even though the detection light may pass through the developer accommodating chamber b150 not loaded with the developer, as shown in fig. 14. In this way, it is possible to: the light intensity or illumination time of the detection light received by the second light receiving element LS202 from the exit surface b42 of the process cartridge b does not reach the preset value (i.e., is lower than the preset value or is completely blocked) of the detection device PD2 of the electronic imaging device P. Thereby simulating that the developer is present in the process cartridge b, the process cartridge b is detected and recognized by the electrophotographic apparatus P, indicating that the target process cartridge is mounted ready for the development work. The operator can perform development detection only by the developer applied on the developing unit 30 to judge whether the developing quality of the process cartridge b meets a predetermined standard. The second member b40b may not be mounted on the process cartridge b first during the development detection, and the detection light may not be guided to the second light receiving element LS202, and the process cartridge b may be mounted with the alignment first member b40a again after the development detection.
(3) If the developing quality of the process cartridge b meets the set standard, the second member b40b is rotated to align the reflecting surface b43 with the first member b40a, so that the detecting light can be reflected by the reflecting surface b43 to the emitting surface b42 and emitted to the outside to be received by the second light receiving element LS202, as shown in fig. 15. Finally, the second component b40b can be fixed on the developing chamber b100 by gluing or welding, so that it can not rotate any more. If the developer that is not developed remains in the developing unit 30, the developer is removed only by the powder suction device.
In this way, through the above steps, the process cartridge b can be mounted in the electrophotographic apparatus P to be detected and identified and the developing operation can be performed without the developer, so that whether the developing quality of the process cartridge b reaches the set standard or not can be detected before the process cartridge b is used in cooperation with the developer carrier bin b 200.
In addition, in order to ensure that the developer applied to the developing unit 30 does not flow into the developer accommodating chamber b150, a sealing sheet b151 may be provided between the developing unit 30 and the developer accommodating chamber b150, with one end of the sealing sheet b151 protruding outward from the side plate. Thus, the user only needs to pull the sealing sheet b151 for removal before using the process cartridge b in cooperation with the developer carrier cartridge b 200.
The second developing detection method of the processing box comprises the following steps:
the step (2) in the first developing detection method of the process cartridge may be: as shown in fig. 16a, the first translucent member b30 further has a base b34, the base b34 is fixed in contact with the upper surface of the developing chamber b100, and a hole b34a is formed in the base b 34. Before performing development inspection of the process cartridge b, a spacer b35 is inserted into the hole b34a, and the spacer b35 is made of a light-blocking material and can block or reduce the light intensity of the inspection light. As shown in fig. 17, in the photodetection process, the spacer b35 located in the first light transmitting element b30 blocks or reduces the intensity of the detection light emitted from the first light emitting element LS101, substantially the same as the method of implementing the step (2) in the first development detection method of the process cartridge described above. It is simulated that the developer exists in the process cartridge b, and the process cartridge b is detected and recognized by the electronic image forming apparatus P. The spacer b35 may be removed after the process cartridge b completes the development test. In addition, a spacer b35 may also be interposed between the first part b40a and the second part b40b of the second translucent member b40, as shown in fig. 16 b.
The third developing detection method of the processing box:
the step (2) in the first developing detection method of the process cartridge may be: as shown in fig. 18, the process cartridge b is further provided therein with a stirring unit b160 and a stirring blade b165 which can stir the developer. The stirring unit b160 receives a driving force from a gear of the power receiving part 210 through a gear (not shown) at one end to rotate the stirring unit b160 in the developer accommodating chamber b 150. The stirring piece b165 may be made of a material that can block or reduce the intensity of the detection light. Before the development inspection of the process cartridge b is performed, the gear at one end of the stirring unit b160 is removed and the stirring unit b160 is rotated so that the stirring blade b165 is positioned between the first light-transmitting member b30 and the second light-transmitting member b40 as viewed in the height direction. In this way, when the gear of the power receiving portion 210 drives the developing unit 30 to rotate, the stirring unit b160 is not driven to rotate, and the reflecting surface b33 reflects the sensing light emitted from the first light emitting element LS101 and then is blocked by the stirring blade b165 which is stationary during the light sensing process, or reduces the light intensity of the sensing light. It is simulated that the developer exists in the process cartridge b, and the process cartridge b is detected and recognized by the electronic image forming apparatus P. After the process cartridge b completes the development detection, the gear of the stirring unit b160 may be reinstalled. In addition, the stirring unit b160 also cleans the inner surfaces of the first light transmitting member b30 and the second light transmitting member b40 when rotating, and prevents the developer from being stuck to affect the irradiation of the detection light.
The development detection method of the process cartridge is four:
the step (2) in the first developing detection method of the process cartridge may be: as shown in fig. 19, before the development detection of the process cartridge b is performed, a certain amount of developer may be replenished through the through opening b155 at the rear portion of the developing hopper b100, and the light intensity of the detection light may be blocked or reduced by the replenished developer. It is simulated that the developer exists in the process cartridge b, and the process cartridge b is detected and recognized by the electronic image forming apparatus P. After the process cartridge b completes the development detection, the replenished developer is removed (sucked or blown).
The developing detection method of the process cartridge comprises the following steps:
the step (2) in the first developing detection method of the process cartridge may be: the first translucent element b30 or/and the second translucent element b40 are made of a material with low light transmittance, or a light intensity reducing layer (such as a frosted layer, a blurred layer, or a patch to reduce the light transmittance area) is additionally arranged (formed by pasting or surface treatment) on the exit surface b42, so that the detection light emitted from the first light-emitting element LS101 can not reach the preset light intensity while the first light detection process and the second light detection process (the detection process of the electronic imaging device) are completed. It is simulated that the developer exists in the process cartridge b, and the process cartridge b is detected and recognized by the electronic image forming apparatus P. Meanwhile, due to the low light transmittance of the light transmitting member, the residual developer in the process cartridge b can be reduced after the process cartridge b is used in cooperation with the developer carrier cartridge b200, so that the developer can be fully utilized.
(method of detecting type of Process Cartridge)
In addition, as shown in fig. 6, the electronic imaging device P is further provided with a pulling member F300 having a hook-shaped structure, and the pulling member F300 is located below the guide rail F200 and driven by a driving motor or other driving mechanism to realize a certain forward and backward displacement. When the process cartridge b and the photosensitive assembly a are mounted in the electrophotographic apparatus P, the supporting portion a21 is supported by the guide rail F200 so that the process cartridge b and the photosensitive assembly a are integrally supported in the electrophotographic apparatus P, after the process cartridge b is mounted, it is necessary to make a detection determination as to the model of the process cartridge to determine whether the model of the process cartridge is suitable for the electronic image forming apparatus P, and at this time, the pulling member F300 rotates the process cartridge b in the clockwise direction with respect to the photosensitive assembly a (relatively different because the photosensitive assembly a is supported by the guide rails F200 through the supporting portion a 21) by the coupling engagement of the coupling arm b3a with the coupling hole a3a by displacing and pulling the cartridge acting member b4 at the bottom of the side plate b1 of the process cartridge b rearward, and the developing unit 30 of the process cartridge b is also separated from the photosensitive unit 10 of the photosensitive assembly a with the rotation of the process cartridge b with respect to the photosensitive assembly a, as shown in fig. 20 and 21.
The detection method of the model of the processing box comprises the following steps: as shown in fig. 22, a third translucent member b50 (i.e., an additional translucent member for determining the model) is further provided on the side plate b1 of the process cartridge of model C1, and the third translucent member b50 has a distance H6 from the first translucent member b30 as viewed from the side direction of the process cartridge C1, before the process cartridge b is pulled by the pulling member F300 to rotate relative to the photosensitive assembly a, the first light emitting element LS101 emits the detection light to the first light transmitting element b30 and is received by the first light receiving element LS102 by reflection (refer to the above-mentioned process cartridge detection process and fig. 7), when the process cartridge b is pulled by the pulling member F300 to rotate relative to the photosensitive assembly a, the first light transmissive member b30 also follows and leaves the first light emitting element LS101, the third light transmitting element b50 moves to the corresponding position of the first light emitting element LS101, and the detecting light emitted from the first light emitting element LS101 to the third light transmitting element b50 is also received by the first light receiving element LS102 through reflection. Since the distance H6 is provided between the third translucent element b50 and the first translucent element b30, the first reflected detection light and the second reflected detection light received by the first light receiving element LS102 have a time difference, and the time difference is recognized and determined by the detection device PD2 of the electronic imaging device, and it is confirmed that the model of the process cartridge is C1, which is applicable to the electronic imaging device with the model of C1. As shown in fig. 23, in another type of the process cartridge C2, if there is a distance H7 between the third translucent element b50 and the first translucent element b30, and the distance H6 is smaller than the distance H7, when the process cartridge C2 is pulled by the pulling member F300 to rotate relative to the photosensitive member a in the electronic image forming apparatus, the time difference between the first reflected detection light and the second reflected detection light received by the first light receiving element LS102 is different from the time difference of the process cartridge C1, as shown in fig. 24, I is the detection light intensity, and T is time. Therefore, the inspection device PD2 of the electronic image forming apparatus recognizes and confirms that the model number of the process cartridge is C2, and the process cartridge is applicable only to the electronic image forming apparatus model number C2, is not applicable to the electronic image forming apparatus model number C1, and is not capable of performing the developing operation with the electronic image forming apparatus model number C1.
The difference in the model numbers of the process cartridge C1 and the process cartridge C2 may be: differences in different regions, different developer capacities, different developing qualities, applicability to different electronic image forming apparatuses, and the like.
The present invention has been described above by way of the embodiments, but the present invention is not limited thereto, and various modifications made within the scope of the technical solution of the present invention according to the idea of the present invention are also covered.
