[0003] In the prior art, an image forming apparatus exposes a photosensitive drum (OPC) using a laser beam emitted from a laser unit, forms a latent image on the photosensitive drum through the exposure, and develops and prints the latent image on an image forming medium such as paper.

[0004] However, when the OPC surface has abnormalities such as damage, dirt, etc., the OPC's ability to sense charge will become abnormal, which will also cause abnormal problems in the image output by the image forming device, giving users a bad experience. The detection signal obtained when the OPC surface is detected needs to be transmitted to the image forming device. If a new terminal for receiving the detection signal is added to the image forming device, the structural design of the image forming device will become more complicated and the cost will be higher.

[0041] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0042] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0043] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0044] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0046] In addition, the term “orthographic projection” used in this article describes the direction of projection, and the orthographic projection on the imaging area can be understood as the radial direction of the photosensitive drum; or it can also be the projection direction perpendicular to the axial direction of the photosensitive drum.

[0047] The electrical signal is obtained by sensing the imaging area of ​​the photosensitive drum

[0048] Currently, there are different detection methods for whether the imaging area on the surface of the photosensitive drum is normal. For example, direct contact with a detection point on the imaging area can be used to determine whether the imaging area is normal by obtaining the electrical signal of the detection point on the imaging area. However, direct contact with the imaging area will cause wear on the surface of the photosensitive drum and affect the service life of the photosensitive drum. In addition, if the detection point on the imaging area is not selected properly, it will easily lead to abnormal judgment results on whether the imaging area is normal.

[0049] In order to solve the above technical problems, the inventors of the present application proposed a solution to judge whether the imaging area is normal by sensing the potential difference between different areas of the imaging area after exposure. In the process of implementing the above solution, the inventors found that in the process of sensing the potential difference, the circuit used for sensing itself has certain inherent signals, which will interfere with the electrical signals generated in the process of sensing the potential difference, resulting in the electrical signals finally obtained being unable to be distinguished or being difficult to distinguish, and it is also impossible to judge whether the imaging area is normal based on the electrical signals generated by the sensing potential difference.

[0050] In order to solve the above problems, Figures 1 to 4As shown, the first aspect of the present application provides a processing box 100, which can be detachably installed in the image forming device body 300, and the processing box 100 includes a box body 110, a photosensitive drum 120 and an inductive component 130. The photosensitive drum 120 is rotatably arranged on the box body 110, and an imaging area for generating an electrostatic latent image is provided on the photosensitive drum 120. The inductive component 130 is used to sense the electrical signal on the imaging area.

[0051] Furthermore, if Figures 5 and 6 As shown, the electric induction component 130 includes a sensing starting portion 131 and a sensing terminal portion 132, the sensing starting portion 131 and the sensing terminal portion 132 respectively correspond to the sensing starting position and the sensing ending position of the sensing area of ​​the electric induction component 130 in the first direction, the maximum distance of the positive projections of the sensing starting portion 131 and the sensing terminal portion 132 on the imaging area in the first direction is L1, the length of the imaging area in the first direction is L2, the first direction is parallel to the axial direction of the photosensitive drum 120, and L1 / L2>1 / 3.

[0052] The above-mentioned processing box 100 is provided with an electric induction component 130 capable of sensing the electric signal on the imaging area. When an electrostatic latent image is formed on the imaging area of ​​the photosensitive drum 120 and passes through the electric induction component 130, based on the potential difference between different areas on the imaging area, the electric induction component 130 obtains an electric signal corresponding to the potential difference, and the circuit where the electric induction component 130 is located also has an inherent signal. The applicant has found that the inherent signal does not change significantly with the increase or decrease of the length of the electric induction component 130, and the maximum distance L between the induction starting portion 131 and the induction terminal portion 132 on the electric induction component 130 capable of performing electric induction in the first direction 1 is larger, that is, the larger the maximum distance between the sensing start position and the sensing end position in the imaging area, the larger the amplitude of the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is, so that the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is more obvious than the inherent signal of the circuit where the electric sensing component 130 is located, and when the ratio L1 / L2 between L1 and the length L2 of the imaging area in the first direction>1 / 3, the interference of the inherent signal in the electric signal can be reduced, so it is easier to obtain the electric signal on the surface of the photosensitive drum 120, which is used to determine whether the surface of the photosensitive drum 120 is normal, and then understand whether the processing box 100 meets expectations.

[0053] In fact, the electric signal transmitted by the electric induction component 130 includes at least two different electric signals, namely, at least the inherent signal of the circuit where the electric induction component 130 is located, and the electric signal obtained by the electric induction component 130 based on the potential difference between different areas on the imaging area. The inherent signal is the property of the circuit where the electric induction component 130 is located, and has nothing to do with the potential difference between different areas on the imaging area of ​​the photosensitive drum 120, so it cannot be used to judge the condition of the photosensitive drum 120, and it will also interfere with the electric signal obtained based on the potential difference. Therefore, in the case where it is difficult to change the inherent signal, by setting the electric induction component 130 and the imaging area, the amplitude of the electric signal obtained based on the potential difference is changed, avoiding the interference of the inherent signal, and making it easier to judge whether the photosensitive drum 120 and the processing box 100 are normal and meet expectations.

[0054] It can be understood that the area on the electric induction component 130 that can obtain an electric signal based on the potential difference on the imaging area is the sensitive area. Generally speaking, the sensitive area is the positive projection of the electric induction component 130 on the imaging area. In the first direction, the sensitive area has a sensing start position and a sensing end position. The sensing start position corresponds to the sensing start portion 131 on the electric induction component 130, and the sensing end position corresponds to the sensing terminal portion 132 on the electric induction component 130.

[0055] In the embodiment of the present invention, examples of image forming devices include: inkjet printers, laser printers, light emitting diode (LED) printers, copiers, scanners or all-in-one fax machines, as well as multi-function peripherals (MFP) that perform the above functions in a single device, etc. The image forming device can form an image on a recording medium such as paper based on image information and a developer such as toner stored in the processing box 100.

[0056] Optionally, the image forming device body 300 includes an image forming control unit 301 and an optical scanning unit. The process of forming an electrostatic latent image on the imaging area is as follows: the charging roller rotates and contacts the photosensitive drum 120, charging the imaging area on the surface of the photosensitive drum 120; the image forming control unit 301 controls the optical scanning unit to emit a light beam based on the image information and scans the imaging area on the surface of the photosensitive drum 120, thereby forming an electrostatic latent image on the imaging area on the surface of the photosensitive drum 120 after being charged by the charging roller.

[0057] It can be understood that the above L1 / L2 value can reduce the interference of the inherent signal in the electrical signal and facilitate the acquisition of the electrical signal on the surface of the photosensitive drum 120 when L1 / L2>1 / 3. For example, the value of L1 / L2 can be 1 / 2, 2 / 3, 3 / 4, 4 / 5, 1, etc. Of course, the value of L1 / L2 is not limited to the above point values.

[0058] In a possible design, the electric signal includes a first electric signal, and the electric induction component 130 is used to generate the first electric signal corresponding to the preset test image information, and the first electric signal is used to determine whether the processing box 100 meets expectations. When the electrostatic latent image corresponding to the preset test image information is formed on the photosensitive drum 120 after exposure, the electric signal sensed by the electric induction component 130 is the first electric signal. At this time, it can be determined based on the first electric signal whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations.

[0059] Specifically, if the image formation control unit 301 issues the same image information in two tasks and the electrostatic latent image formed on the photosensitive drum 120 is the same, the electrical signals sensed by the electric sensing component 130 twice should also be the same or similar. Therefore, the electrical signal corresponding to the preset test image information obtained by the electric sensing component 130 when there is no abnormality in the photosensitive drum 120 or the information after processing the electrical signal corresponding to the aforementioned preset test image information can be used as reference information. When the electrostatic latent image on the imaging area corresponds to the preset test image information, the first electrical signal obtained by the electric sensing component 130 can be compared with the reference information, and based on the results obtained after the comparison, it can be judged whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations. It is understandable that even if the electrostatic latent images formed twice on the imaging area of ​​the photosensitive drum 120 are the same, there may be certain differences in the electrical signal obtained by the inductive component 130. Therefore, the electrical signal obtained by the inductive component 130 can be extracted and compared with the characteristic value in the reference information; or based on the similarity between the electrical signal obtained by the inductive component 130 and the reference information, it can be judged whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations.

[0060] Optionally, the first electrical signal may contain the above-mentioned inherent signal, or may be a signal generated after filtering out the inherent signal.

[0061] In a possible design, the electric signal includes a first electric signal, the electric induction component 130 is used to generate the first electric signal corresponding to the preset test image information, the first electric signal is used to generate a second electric signal different from the first electric signal, and the second electric signal is used to determine whether the processing box 100 meets expectations. The first electric signal can be processed to obtain a second electric signal that meets the requirements, which is convenient for comparison and judgment of whether the processing box 100 meets expectations.

[0062] In other embodiments, based on different determination methods, the first electrical signal may be directly used for comparison to determine whether the processing box 100 meets expectations.

[0063] In a possible design, the inductive component 130 is spaced apart from the imaging area, and the electric signal is a voltage signal. When the inductive component 130 is spaced apart from the imaging area, the inductive component 130 and the surface of the photosensitive drum 120 actually form a capacitor-like structure. When there is an electrostatic latent image on the imaging area, there is a potential difference between different areas on the imaging area. Therefore, when the inductive component 130 changes from being relative to one area on the imaging area to being relative to another area with a different potential on the imaging area, the inductive component 130 will generate an electric signal accordingly. The above electric signal is related to the electrostatic latent image on the imaging area. If there is an abnormality on the surface of the photosensitive drum 120, it will cause the electrostatic latent image to be abnormal, which will affect the properties of the electric signal. Therefore, it can be judged whether the imaging area on the surface of the photosensitive drum 120 is normal based on the electric signal.

[0064] In one possible design, Figure 3 As shown, the box body 110 further includes a scraper blade 111, and the scraper blade 111 includes an insulating portion, one side of the insulating portion contacts the surface of the imaging area, and the inductive component 130 is arranged on the other side of the insulating portion away from the imaging area.

[0065] Furthermore, if Figure 3 As shown, the scraper blade 111 is a cleaning scraper blade 111a, and the scraper blade 111 can be used to scrape the powder on the surface of the photosensitive drum 120, and the distance between the scraper blade 111 and the photosensitive drum 120 is relatively close, so the inductive component 130 can be arranged on the scraper blade 111, so that a capacitor structure can be formed between the inductive component 130 and the surface of the photosensitive drum 120. In addition, the scraper blade 111 will have direct contact with the photosensitive drum 120, so the inductive component 130 is arranged on the other side of the insulating portion of the scraper blade 111 away from the imaging area to prevent the inductive component 130 from being electrically connected to the surface of the photosensitive drum 120, so that the inductive component 130 can realize electrical induction of the imaging area on the surface of the photosensitive drum 120 through the capacitor structure. When toner is adsorbed on the surface of the photosensitive drum 120 and has been transferred, the cleaning blade 111a can scrape off the residual toner on the photosensitive drum 120, and the residual toner can be stored in the waste toner bin 112, so that the imaging area on the surface of the photosensitive drum 120 can be kept clean before the next printing task starts, and will not interfere with the imaging of the next printing task.

[0066] Furthermore, if Figure 3 As shown, the scraper blade 111 is a sealing scraper blade 111 b, which is used to seal the waste toner bin 112 to prevent the waste toner in the waste toner bin 112 from leaking out of the waste toner bin 112 and thus contaminating the image forming device.

[0067] It can be understood that any area on the process box 100 that can form a capacitor structure or a capacitor-like structure with the imaging area on the surface of the photosensitive drum 120 can be the area where the electric induction component 130 is set. At the same time, when the electric induction component 130 performs electric induction on the photosensitive drum 120, the photosensitive drum 120 should have been exposed by the optical scanning unit, that is, the imaging area on the surface of the photosensitive drum 120 already has an electrostatic latent image. Therefore, in other embodiments, if other areas of the process box 100 meet the above conditions, the electric induction component 130 can also be set at other positions or areas other than the scraper 111.

[0068] In a possible design, the length of the positive projection of the insulating part on the imaging area in the first direction is L3, and L3 ≥ L1. Through the above arrangement, it is ensured that after the inductive component 130 that meets the ratio requirement is installed on the insulating part, there will be no situation where part of the inductive component 130 has no installation position, so that the installation of the inductive component 130 is more stable and the electrical signal can be obtained more accurately.

[0069] In a possible design, the electric induction component 130 contacts the surface of the imaging area, and the electric signal is a current signal. The electric induction component 130 may also directly contact the imaging area on the surface of the photosensitive drum 120, and obtain the current signal to determine whether the photosensitive drum 120 is normal.

[0070] It can be understood that both the current signal and the voltage signal can correspond to the potential difference appearing in the imaging area, and therefore can be used to determine whether the photosensitive drum 120 is normal. In addition, if there are other types of electrical signals that can change corresponding to the potential difference appearing in the imaging area, they can also be used to determine whether the photosensitive drum 120 is normal.

[0071] In a possible design, the processing box 100 further includes a conversion circuit, which is used to convert the current signal sensed by the electric induction component 130 into a voltage signal. After the current signal is obtained by the electric induction component 130 contacting the imaging area on the surface of the photosensitive drum 120, the current signal can also be processed to be converted into a voltage signal, which can also be used to determine whether the photosensitive drum 120 is normal.

[0072] In one possible design, Figure 5 As shown, the electric induction component 130 includes a strip-shaped conductive strip 130a. The strip-shaped conductive strip 130a is easy to install, and multiple areas on the conductive strip 130a can be used to sense electric signals.

[0073] In one possible design, Figure 6As shown, the inductive component 130 includes at least two inductive inductor units 130b arranged at intervals. One of the two inductive inductor units 130b arranged at intervals includes an inductive starting portion 131, and the other inductive inductor unit 130b includes an inductive terminal portion 132, which can also obtain electrical signals and reduce interference with inherent signals on the basis of meeting conditions. The two adjacent inductive inductor units 130b arranged at intervals are electrically connected through wires; or different inductive inductor units 130b are electrically connected to different wires respectively, and the different wires are finally connected to the same circuit, and this circuit can also transmit electrical signals.

[0074] like Figures 1 to 3 As shown, the second aspect of the present application provides a processing box 100, which can be detachably installed in an image forming device. The processing box 100 includes a box body 110 and a photosensitive drum 120, which can be rotatably arranged on the box body 110. The photosensitive drum 120 is provided with an imaging area that can generate an electrostatic latent image.

[0075] Furthermore, if Figure 7 As shown, the box body 110 has an inductive component setting area 113, and the inductive component setting area 113 is used to set the inductive component 130. When the inductive component 130 is installed in the inductive component setting area 113, the inductive component 130 is used to sense the electrical signal on the imaging area. The inductive component setting area 113 includes a first area corresponding to the inductive starting part 131 of the potential inductive component and a second area corresponding to the inductive terminal part 132 of the potential inductive component. The maximum distance of the positive projections of the first area and the second area on the imaging area in the first direction is L1, and the length of the imaging area along the first direction is L2, L1 / L2>1 / 3, and the first direction is parallel to the axial direction of the photosensitive drum 120.

[0076] The processing box 100 is provided with an inductive component setting area 113 for setting an inductive component 130. After being installed on the processing box 100, the inductive component 130 can sense the electrical signal on the imaging area. When an electrostatic latent image is formed on the imaging area of ​​the photosensitive drum 120 and passes through the inductive component 130, based on the potential difference between different areas on the imaging area, the inductive component 130 can obtain an electrical signal corresponding to the potential difference. At the same time, the circuit where the inductive component 130 is located also has an inherent signal. The applicant has found that the inherent signal does not change significantly with the increase or decrease in the length of the inductive component 130. The inductive starting portion 130 on the inductive component 130 that can perform electrical induction 1 and the sensing terminal portion 132 in the first direction is larger, that is, the larger the maximum distance L1 between the first area and the second area between the positive projections on the imaging area is, the larger the amplitude of the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is, so that the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is more obvious than the inherent signal of the circuit where the electric sensing component 130 is located, and when the ratio L1 / L2 between L1 and the length L2 of the imaging area in the first direction is greater than 1 / 3, the interference of the inherent signal in the electric signal can be reduced, so that it is easier to obtain the electric signal on the surface of the photosensitive drum 120, which is used to determine whether the surface of the photosensitive drum 120 is normal, and then understand whether the processing box 100 meets expectations.

[0077] It is understandable that the above-mentioned L1 / L2 value can reduce the interference of the inherent signal in the electric signal and make it easier to obtain the electric signal on the surface of the photosensitive drum 120 when L1 / L2>1 / 3. For example, the value of L1 / L2 can be 1 / 2, 2 / 3, 3 / 4, 4 / 5, 1, etc. Of course, the value of L1 / L2 is not limited to the above-mentioned point value. That is, based on the different processing boxes 100 used, the size of the inductive component 130 can be set accordingly, so that after the inductive component 130 is installed in the inductive component setting area 113 of the processing box 100, L1 / L2>1 / 3.

[0078] In a possible design, the electric signal includes a first electric signal. When the electric induction component 130 is installed in the electric induction component setting area 113, the electric induction component 130 is used to generate a first electric signal corresponding to the preset test image information, and the first electric signal is used to determine whether the processing box 100 meets expectations. After the electric induction component 130 is installed in the electric induction component setting area 113, when the electrostatic latent image corresponding to the preset test image information is formed on the photosensitive drum 120 after exposure, the electric signal sensed by the electric induction component 130 is the first electric signal. At this time, it can be determined based on the first electric signal whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations.

[0079] Specifically, if the image formation control unit 301 issues the same image information in two tasks and the electrostatic latent image formed on the photosensitive drum 120 is the same, the electrical signals sensed by the electric sensing component 130 twice should also be the same or similar. Therefore, the electrical signal corresponding to the preset test image information obtained by the electric sensing component 130 when there is no abnormality in the photosensitive drum 120 or the information after processing the electrical signal corresponding to the aforementioned preset test image information can be used as reference information. When the electrostatic latent image on the imaging area corresponds to the preset test image information, the first electrical signal obtained by the electric sensing component 130 can be compared with the reference information, and based on the results obtained after the comparison, it can be judged whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations.

[0080] It is understandable that even if the electrostatic latent images formed twice on the imaging area of ​​the photosensitive drum 120 are the same, there may be certain differences in the electrical signal obtained by the inductive component 130. Therefore, the electrical signal obtained by the inductive component 130 can be extracted and compared with the characteristic value in the reference information; or based on the similarity between the electrical signal obtained by the inductive component 130 and the reference information, it can be judged whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations.

[0081] Optionally, the first electrical signal may contain the above-mentioned inherent signal, or may be a signal generated after filtering out the inherent signal.

[0082] In a possible design, the electric signal includes a first electric signal, the electric induction component 130 is used to generate the first electric signal corresponding to the preset test image information, the first electric signal is used to generate a second electric signal different from the first electric signal, and the second electric signal is used to determine whether the processing box 100 meets expectations. The first electric signal can be processed to obtain a second electric signal that meets the requirements, which is convenient for comparison and judgment of whether the processing box 100 meets expectations.

[0083] In other embodiments, based on different determination methods, the first electrical signal may be directly used for comparison to determine whether the processing box 100 meets expectations.

[0084] In a possible design, the inductive component setting area 113 is spaced apart from the imaging area, so that the inductive component 130 is spaced apart from the imaging area after being installed in the inductive component setting area 113, and the electric signal is a voltage signal. By spacing the inductive component setting area 113 and the imaging area, so that after the inductive component 130 is installed in the inductive component setting area 113, the inductive component 130 and the surface of the photosensitive drum 120 actually form a capacitor-like structure, and when there is an electrostatic latent image on the imaging area, there is a potential difference between different areas on the imaging area, so when the imaging area relative to the inductive component 130 changes from being relative to one area on the imaging area to being relative to another area with different potential on the imaging area, the inductive component 130 will generate an electric signal accordingly, and the above electric signal is related to the electrostatic latent image on the imaging area. If there is an abnormality on the surface of the photosensitive drum 120, it will cause the distribution of the electrostatic latent image to be abnormal, thereby affecting the properties of the electric signal, so it can be judged whether the imaging area on the surface of the photosensitive drum 120 is normal according to the electric signal.

[0085] In one possible design, Figure 3 As shown, the box body 110 also includes a scraper 111, and the scraper 111 includes an insulating portion, one side of the insulating portion contacts the surface of the imaging area, and the inductive component setting area 113 is located on the other side of the insulating portion away from the imaging area.

[0086] Furthermore, if Figure 3 As shown, the scraper blade 111 is a cleaning scraper blade 111a. The scraper blade 111 can be used to scrape the powder on the surface of the photosensitive drum 120, and the distance between the scraper blade 111 and the photosensitive drum 120 is relatively close, so the inductive component setting area 113 can be set on the scraper blade 111, so that after the inductive component 130 is installed in the inductive component setting area 113, a capacitor structure can be formed with the surface of the photosensitive drum 120. In addition, the scraper blade 111 and the photosensitive drum 120 will have direct contact, so the inductive component setting area 113 is set on the other side of the insulating part of the scraper blade 111 away from the imaging area, so as to prevent the inductive component 130 from being electrically connected to the surface of the photosensitive drum 120, so that the inductive component 130 can realize the electrical induction of the imaging area on the surface of the photosensitive drum 120 through the capacitor structure. When toner is adsorbed on the surface of the photosensitive drum 120 and has been transferred, the cleaning blade 111a can scrape off the residual toner on the photosensitive drum 120, and the residual toner can be stored in the waste toner bin 112, so that the imaging area on the surface of the photosensitive drum 120 can be kept clean before the next printing task starts, and will not interfere with the imaging of the next printing task.

[0087] Furthermore, if Figure 3As shown, the scraper blade 111 is a sealing scraper blade 111 b, which is used to seal the waste toner bin 112 to prevent the waste toner in the waste toner bin 112 from leaking out of the waste toner bin 112 and thus contaminating the image forming device.

[0088] It is understandable that any area on the process box 100 that can form a capacitor structure or a capacitor-like structure with the imaging area on the surface of the photosensitive drum 120 can be the area where the electric induction component 130 is set. At the same time, when the electric induction component 130 performs electric induction on the photosensitive drum 120, the photosensitive drum 120 should have been exposed by the optical scanning unit, that is, the imaging area on the surface of the photosensitive drum 120 already has an electrostatic latent image. Therefore, in other embodiments, other areas of the process box 100 can also be set at other positions or areas except the scraper 111 if the above conditions are met.

[0089] In a possible design, the length of the positive projection of the insulating part on the imaging area in the first direction is L3, and L3 ≥ L1. Through the above arrangement, it is ensured that after the inductive component 130 that meets the ratio requirement is installed on the insulating part, there will be no situation where part of the inductive component 130 has no installation position, so that the installation of the inductive component 130 is more stable and the electrical signal can be obtained more accurately.

[0090] In a possible design, when the inductive component 130 is installed in the inductive component setting area 113, the inductive component 130 contacts the surface of the imaging area, and the electrical signal is a current signal. The inductive component 130 can also directly contact the imaging area on the surface of the photosensitive drum 120, and the current signal is obtained to determine whether the photosensitive drum 120 is normal.

[0091] It can be understood that both the current signal and the voltage signal can correspond to the potential difference appearing in the imaging area, and therefore can be used to determine whether the photosensitive drum 120 is normal. In addition, if there are other types of electrical signals that can change corresponding to the potential difference appearing in the imaging area, they can also be used to determine whether the photosensitive drum 120 is normal.

[0092] In a possible design, the processing box 100 further includes a conversion circuit, which is used to convert the current signal sensed by the electric induction component 130 into a voltage signal. After the current signal is obtained by the electric induction component 130 contacting the imaging area on the surface of the photosensitive drum 120, the current signal can also be processed to be converted into a voltage signal, which can also be used to determine whether the photosensitive drum 120 is normal.

[0093] In one possible design, Figure 5 As shown, the electric induction component 130 includes a strip-shaped conductive strip 130a. The strip-shaped conductive strip 130a is easy to install, and multiple areas on the conductive strip 130a can be used to sense electric signals.

[0094] In one possible design, Figure 6 As shown, the inductive component 130 includes at least two inductive inductor units 130b arranged at intervals. One of the two inductive inductor units 130b arranged at intervals includes an inductive starting portion 131, and the other inductive inductor unit 130b includes an inductive terminal portion 132, which can also obtain electrical signals and reduce interference with inherent signals on the basis of meeting conditions. The two adjacent inductive inductor units 130b arranged at intervals are electrically connected through wires; or different inductive inductor units 130b are electrically connected to different wires respectively, and the different wires are finally connected to the same circuit, and this circuit can also transmit electrical signals.

[0095] A third aspect of the present application provides an image forming device, comprising the process box 100 as described above.

[0096] In the above-mentioned image forming device, since the processing box 100 is provided with an electric induction component 130 capable of sensing the electric signal on the imaging area, when an electrostatic latent image is formed on the imaging area of ​​the photosensitive drum 120 and passes through the electric induction component 130, based on the potential difference between different areas on the imaging area, the electric induction component 130 can obtain an electric signal corresponding to the potential difference. At the same time, the circuit where the electric induction component 130 is located also has an inherent signal. The applicant has found that the inherent signal does not change significantly with the increase or decrease in the length of the electric induction component 130, and the induction starting portion 131 and the induction terminal portion 132 on the electric induction component 130 capable of performing electric induction are in the first direction. The larger the maximum distance L1 is, that is, the larger the maximum distance between the positive projections of the sensing start position and the sensing end position on the imaging area, the larger the amplitude of the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is, so that the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is more obvious than the inherent signal of the circuit where the electric sensing component 130 is located, and when the ratio L1 / L2 between L1 and the length L2 of the imaging area in the first direction is greater than 1 / 3, the interference of the inherent signal in the electric signal can be reduced. Therefore, it is easier to obtain the electric signal on the surface of the photosensitive drum 120, which is used to determine whether the surface of the photosensitive drum 120 is normal, and then to understand whether the processing box 100 meets expectations.

[0097] In one possible design, Figure 8As shown, the image forming device further includes an image forming control unit 301, which is used to control the image forming device to form a predetermined electrostatic latent image on the surface of the photosensitive drum 120, and to judge whether the processing box 100 meets expectations based on the second electric signal generated by the first electric signal output by the electric induction component 130. The image forming control unit 301 can issue a task to form a predetermined electrostatic latent image on the surface of the photosensitive drum 120. At this time, the electric induction component 130 can sense the first electric signal based on the imaging area on the surface of the photosensitive drum 120, and the first electric signal can be transmitted or processed to form a second electric signal. The image forming control unit 301 can judge whether the processing box 100 meets expectations based on the second electric signal.

[0098] It can be understood that, based on the predetermined electrostatic latent image, the electrical signals obtained by the inductive component 130 at different times may be the same or similar. Therefore, the image formation control unit 301 may pre-store electrical signal information corresponding to the predetermined electrostatic latent image. When the image formation control unit 301 controls the surface of the photosensitive drum 120 to form a predetermined electrostatic latent image, the image formation control unit 301 may compare the electrical signal obtained by the inductive component 130 with the pre-stored electrical signal information to determine whether the processing box 100 meets expectations.

[0099] like Figure 1 , Figure 2 , Figures 4 to 6 As shown, the fourth aspect of the present application provides an electric sensing component 130, which is used to be set on the processing box 100. When the electric sensing component 130 is installed on the processing box 100, the electric sensing component 130 is used to sense the electrical signal on the imaging area of ​​the photosensitive drum 120; wherein, the potential sensing component includes a sensing starting portion 131 and a sensing terminal portion 132, and the sensing starting portion 131 and the sensing terminal portion 132 respectively correspond to the sensing starting position and the sensing ending position of the sensing area of ​​the electric sensing component 130 in the first direction, and the maximum distance of the positive projections of the sensing starting portion 131 and the sensing terminal portion 132 on the imaging area in the first direction is L1, and the length of the imaging area in the first direction is L2, and the first direction is parallel to the axial direction of the photosensitive drum 120, and L1 / L2>1 / 3.

[0100] The above-mentioned inductive component 130 can be installed on the processing box 100. When the inductive component 130 is installed on the processing box 100, the inductive component 130 can sense the electrical signal on the imaging area of ​​the photosensitive drum 120. When an electrostatic latent image is formed on the imaging area of ​​the photosensitive drum 120 and passes through the inductive component 130, based on the potential difference between different areas on the imaging area, the inductive component 130 can obtain an electrical signal corresponding to the potential difference. At the same time, the circuit where the inductive component 130 is located also has an inherent signal. The applicant has found that the inherent signal does not change significantly with the increase or decrease of the length of the inductive component 130, and the inductive starting portion 131 and the inductive starting portion 131 on the inductive component 130 that can perform electrical induction are The larger the maximum distance L1 of the sensing terminal portion 132 in the first direction, that is, the larger the maximum distance between the sensing start position and the sensing end position in their positive projections on the imaging area, the larger the amplitude of the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is, so that the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is more obvious than the inherent signal of the circuit in which the electric sensing component 130 is located, and when the ratio L1 / L2 between L1 and the length L2 of the imaging area in the first direction>1 / 3, the interference of the inherent signal in the electric signal can be reduced, so that it is easier to obtain the electric signal on the surface of the photosensitive drum 120, which is used to determine whether the surface of the photosensitive drum 120 is normal, and then to understand whether the processing box 100 meets expectations.

[0101] Optionally, the inductive component 130 is spaced apart from the imaging area. When the inductive component 130 is spaced apart from the imaging area, the inductive component 130 and the surface of the photosensitive drum 120 actually form a capacitor-like structure. When there is an electrostatic latent image on the imaging area, there is a potential difference between different areas on the imaging area. Therefore, when the inductive component 130 changes from being relative to one area on the imaging area to being relative to another area with a different potential on the imaging area, the inductive component 130 will generate an electrical signal accordingly. The electrical signal is related to the electrostatic latent image on the imaging area. If there is an abnormality on the surface of the photosensitive drum 120, it will cause the distribution of the electrostatic latent image to be abnormal, thereby affecting the properties of the electrical signal. Therefore, it can be determined whether the imaging area on the surface of the photosensitive drum 120 is normal based on the electrical signal.

[0102] In one possible design, Figure 5 and Figure 6As shown, the inductive component 130 includes a scraper blade 111 and a conductive portion. The scraper blade 111 is used to be arranged on the processing box 100, and the conductive portion is arranged on the scraper blade 111. The two parts of the conductive portion are respectively an inductive starting portion 131 and an inductive terminal portion 132. The scraper blade 111 can be used to scrape the powder on the surface of the photosensitive drum 120, and the distance between the scraper blade 111 and the photosensitive drum 120 is relatively close, so the inductive component 130 can be arranged on the scraper blade 111, so that the inductive component 130 and the surface of the photosensitive drum 120 can form a capacitor structure. In addition, the scraper blade 111 and the photosensitive drum 120 will have direct contact, so the inductive component 130 is arranged on the other side of the insulating portion of the scraper blade 111 away from the imaging area, to prevent the inductive component 130 from being electrically connected to the surface of the photosensitive drum 120, so that the inductive component 130 can realize the electrical induction of the imaging area on the surface of the photosensitive drum 120 through the capacitor structure.

[0103] Furthermore, if Figure 3 As shown, the scraper blade 111 is a cleaning scraper blade 111a. When the surface of the photosensitive drum 120 adsorbs carbon powder and is transferred, the cleaning scraper blade 111a can scrape off the residual carbon powder on the photosensitive drum 120. The residual carbon powder can be stored in the waste toner bin 112, so that the imaging area on the surface of the photosensitive drum 120 can be kept clean before the next printing task starts, and will not interfere with the imaging of the next printing task.

[0104] Furthermore, if Figure 3 As shown, the scraper blade 111 is a sealing scraper blade 111 b, which is used to seal the waste toner bin 112 to prevent the waste toner in the waste toner bin 112 from leaking out of the waste toner bin 112 and thus contaminating the image forming device.

[0105] It can be understood that any area on the process box 100 that can form a capacitor structure or a capacitor-like structure with the imaging area on the surface of the photosensitive drum 120 can be the area where the electric induction component 130 is set. At the same time, when the electric induction component 130 performs electric induction on the photosensitive drum 120, the photosensitive drum 120 should have been exposed by the optical scanning unit, that is, the imaging area on the surface of the photosensitive drum 120 already has an electrostatic latent image. Therefore, in other embodiments, if other areas of the process box 100 meet the above conditions, the electric induction component 130 can also be set at other positions or areas other than the scraper 111.

[0106] In one possible design, Figure 5 As shown, the electric induction component 130 includes a strip-shaped conductive strip 130a. The strip-shaped conductive strip 130a is easy to install, and multiple areas on the conductive strip 130a can be used to sense electric signals.

[0107] In one possible design, Figure 6As shown, the inductive component 130 includes at least two inductive inductor units 130b arranged at intervals. One of the two inductive inductor units 130b arranged at intervals includes an inductive starting portion 131, and the other inductive inductor unit 130b includes an inductive terminal portion 132, which can also obtain electrical signals and reduce interference with inherent signals on the basis of meeting conditions. The two adjacent inductive inductor units 130b arranged at intervals are electrically connected through wires; or different inductive inductor units 130b are electrically connected to different wires respectively, and the different wires are finally connected to the same circuit, and this circuit can also transmit electrical signals.

[0108] like Figures 1 to 4 As shown, the fifth aspect of the present application provides an image forming device, including a processing box 100 and an inductive component 130 as described above, wherein the inductive component 130 is disposed on the processing box 100 .

[0109] In the above-mentioned image forming device, when the inductive component 130 is installed on the processing box 100, the inductive component 130 can sense the electrical signal on the imaging area of ​​the photosensitive drum 120. When an electrostatic latent image is formed on the imaging area of ​​the photosensitive drum 120 and passes through the inductive component 130, based on the potential difference between different areas on the imaging area, the inductive component 130 can obtain an electrical signal corresponding to the potential difference. At the same time, the circuit where the inductive component 130 is located also has an inherent signal. The applicant has found that the inherent signal does not change significantly with the increase or decrease of the length of the inductive component 130. The inductive starting portion 131 and the inductive terminal portion 130 on the inductive component 130 that can perform electrical induction are The larger the maximum distance L1 in the first direction, that is, the larger the maximum distance between the orthographic projections of the sensing start position and the sensing end position on the imaging area, the larger the amplitude of the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is, so that the electric signal corresponding to the potential difference obtained by the electric sensing component 130 is more obvious than the inherent signal of the circuit where the electric sensing component 130 is located, and when the ratio L1 / L2 between L1 and the length L2 of the imaging area in the first direction is greater than 1 / 3, the interference of the inherent signal in the electric signal can be reduced, so that it is easier to obtain the electric signal on the surface of the photosensitive drum 120, which is used to judge whether the surface of the photosensitive drum 120 is normal, and then understand whether the processing box 100 meets expectations.

[0110] In one possible design, Figure 8As shown, the image forming device further includes an image forming control unit 301, which is used to control the image forming device to form a predetermined electrostatic latent image on the surface of the photosensitive drum 120, and to judge whether the processing box 100 meets expectations based on the second electric signal generated by the first electric signal output by the electric induction component 130. The image forming control unit 301 can issue a task to form a predetermined electrostatic latent image on the surface of the photosensitive drum 120. At this time, the electric induction component 130 can sense the first electric signal based on the imaging area on the surface of the photosensitive drum 120, and the first electric signal can be processed to form a second electric signal. The image forming control unit 301 can judge whether the processing box 100 meets expectations based on the second electric signal.

[0111] It can be understood that, based on the predetermined electrostatic latent image, the electrical signals obtained by the inductive component 130 at different times may be the same or similar. Therefore, the image formation control unit 301 may pre-store electrical signal information corresponding to the predetermined electrostatic latent image. When the image formation control unit 301 controls the surface of the photosensitive drum 120 to form a predetermined electrostatic latent image, the image formation control unit 301 may compare the electrical signal obtained by the inductive component 130 with the pre-stored electrical signal information to determine whether the processing box 100 meets expectations.

[0112] Transmits electrical signals to the image forming device body 300

[0113] When the processing box 100 has a pre-installed or installed inductive component 130, and after the inductive component 130 obtains an electrical signal, the electrical signal can be transmitted to the image forming device body 300. The image forming device body 300 can judge whether the photosensitive drum 120 is normal and whether the processing box 100 meets expectations based on the electrical signal.

[0114] In one possible design, Figures 1 to 4 , Figure 8 As shown, the process cartridge 100 includes a first connecting component 210, the first connecting component 210 is electrically connected to the electric induction component 130, and the first connecting component 210 includes a first output terminal 211, and the first output terminal 211 is used to electrically connect to the image forming device body 300 so as to transmit to the image forming device body 300 an electric signal used to determine whether the process cartridge 100 meets expectations. The first connecting component 210 can be electrically connected to the electric induction component 130 and the image forming device body 300, respectively, so that the electric signal obtained by the electric induction component 130 can be directly transmitted to the image forming device body 300, and at this time, the image forming device body 300 can determine whether the process cartridge 100 meets expectations based on the electric signal.

[0115] Specifically, the first output terminal 211 is used to be electrically connected to the image forming control unit 301 of the image forming apparatus body 300, and can transmit an electrical signal to the image forming control unit 301, and the image forming control unit 301 determines whether the processing box 100 meets expectations based on the electrical signal.

[0116] Furthermore, if Figure 8 and Fig. 9 As shown, the processing box 100 also includes a signal processing module 220, which is disposed on the first connecting component 210 and is electrically connected to the first output terminal 211. The signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The electrical signal obtained by the electric induction component 130 can be processed by the signal processing module 220 to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and the circuit in the image forming device can also be protected.

[0117] In a possible design, the first output terminal 211 is also used to electrically connect the signal processing module 220. When the first output terminal 211 is electrically connected to the signal processing module 220, the signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The signal processing module 220 may not be set on the storage device 140. In this case, when the signal processing module 220 is electrically connected to the first output terminal 211, the signal processing module 220 processes the electrical signal to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and the circuit in the image forming device can also be protected. That is, the processing box itself may not include the signal processing module 220. In order to protect the circuit in the image forming device, the signal processing module 220 is additionally installed.

[0118] Furthermore, if Fig. 9 As shown, the signal processing module 220 includes a voltage dividing module 221, which is used to perform voltage dividing processing on the signal received by the voltage dividing module 221 to obtain a voltage divided signal; and / or a voltage stabilizing module 222, which is used to perform voltage stabilizing processing on the signal received by the voltage stabilizing module 222 to obtain a voltage stabilizing signal; and / or a rectifier module 223, which is used to perform rectification processing on the signal received by the rectifier module 223 to obtain a rectified signal. The voltage dividing module 221 can reduce the voltage of the signal transmitted to the image forming device body 300 to prevent excessive voltage from damaging the circuit in the image forming device; the voltage stabilizing module 222 can prevent excessive voltage from damaging the circuit in the image forming device; the rectifier module 223 can rectify the signal and filter out the part of the signal that cannot be processed, so as to facilitate the image forming device body 300 to process or identify, and also protect the circuit in the image forming device.

[0119] It is understandable that the signal processing module 220 can process the electrical signal and protect the circuit by using at least one of the voltage divider module 221, the voltage regulator module 222, and the rectifier module 223. Of course, when the signal processing module 220 uses the voltage divider module 221, the voltage regulator module 222, and the rectifier module 223 at the same time, it has a better protection effect. In addition, the signal processing module 220 can also use other modules that can protect the circuit.

[0120] Specifically, Fig. 9 As shown, the voltage dividing module 221 includes at least one voltage dividing resistor, which can play a voltage dividing role by connecting the voltage dividing resistor in series between the inductive component 130 and the image forming device body 300, thereby reducing the voltage of the electrical signal transmitted from the first connecting component 210 to the image forming device body. Of course, the voltage dividing module 221 can also be other components or circuits that can play a voltage dividing role.

[0121] Specifically, Fig. 9 As shown, the voltage stabilizing module 222 includes a voltage stabilizing diode, one end of which is connected to the first connecting component 210 and the other end is grounded, which can play a role in voltage stabilization to prevent excessive voltage from damaging the circuit. Of course, the voltage stabilizing module 222 can also be other components or circuits that can play a role in voltage stabilization.

[0122] Specifically, Fig. 9 As shown, the rectifier module 223 includes a unidirectional rectifier diode. By connecting the unidirectional rectifier diode in series between the inductive component 130 and the image forming device body 300, it can filter out negative voltage signals, prevent breakdown of the modules connected thereto, and protect the circuit from damage. Among them, in this embodiment, the unidirectional rectifier diode mainly filters out negative voltages in electrical signals to meet the requirements of the image forming device body for electrical signals. Of course, the rectifier module 223 can also be other components or circuits that can play a rectifying role. At the same time, according to different needs, the rectifier module 223 can also be used to remove the positive part of the electrical signal.

[0123] When the processing box 100 has a pre-installed or installed inductive component 130, and after the inductive component 130 obtains the electric signal, the electric signal can be transmitted to the image forming device body 300. However, if a terminal for receiving the above-mentioned electric signal is added on the image forming device body 300 side of the image forming device, the complexity and cost of the image forming device mechanism design will increase.

[0124] To solve the above problems, Figures 1 to 4As shown, the present application provides a processing box 100 in the sixth aspect, which can be detachably installed in the image forming device body 300, including a box body 110, a photosensitive drum 120 and an electric induction component 130. The photosensitive drum 120 is rotatably arranged on the box body 110, and an imaging area for generating an electrostatic latent image is provided on the photosensitive drum 120. The electric induction component 130 is used to sense the electrical signal on the imaging area.

[0125] Furthermore, if Fig.10 As shown, the process cartridge 100 further includes a storage device 140 , and the storage device 140 includes an electrical contact 141 , and the electrical contact 141 is used to electrically connect to an electrical contact portion 3011 provided on the image forming apparatus body 300 .

[0126] Furthermore, if Fig.10 As shown, the processing box 100 also includes a first electrical connection component, which includes a conveying end 204, and the conveying end 204 is electrically connected to the electric induction component 130, and is used to electrically connect to the electric contact part 3011. The conveying end 204 is used to obtain an electrical signal of an imaging area on the photosensitive drum 120 of the processing box 100 that can generate an electrostatic latent image, and when the conveying end 204 is electrically connected to the electric contact part 3011, transmit the electrical signal generated based on the electrical signal to the electric contact part 3011 for determining whether the processing box 100 meets expectations.

[0127] In the above-mentioned processing box 100, the electrical contact 141 of the storage device 140 is used to be electrically connected to the electrical contact portion 3011 on the image forming device body 300, and the electric sensing component 130 is also electrically connected to the electric contact portion 3011 through the conveying end 204 of the first electrical connection component. At this time, there is no need to add new contacts on the side of the image forming device body 300, that is, the electric signal of the imaging area of ​​the photosensitive drum 120 sensed by the electric sensing component 130 can be transmitted to the image forming device body 300, which can effectively reduce the manufacturing cost and design difficulty.

[0128] In fact, if a new contact point is added on the image forming device body 300 side, the circuit or structure on the image forming device body 300 side needs to be modified accordingly, and the original circuit and structure on the image forming device body 300 side are relatively complex, so the modification will greatly increase the cost and difficulty of design and manufacturing. By reusing the electrical contact part 3011 on the image forming device body 300 side, the design can be effectively simplified and the cost can be reduced. At the same time, due to the simplification of the circuit, the stability of the system on the image forming device body 300 side can also be improved.

[0129] Optionally, in the process box 100 of the present aspect, the first electrical connection component may be the following second connection component 230, and the delivery end 204 may be the following second output end. That is, the process box 100 includes a storage device 140 and a second connection component 230, the storage device 140 includes a substrate 142 and an electrical contact 141 electrically connected to the substrate 142, the electrical contact 141 is used to electrically connect to an electrical contact portion 3011 provided on the image forming device body 300, the second connection component 230 is electrically connected to the electrical induction component 130, and the second connection component 230 includes a second output end, and the second output end is used to electrically connect to the electrical contact portion 3011.

[0130] In fact, after receiving the electric signal obtained by the electric induction component 130, the second connecting component 230 transmits the electric signal to the image forming device body 300 when the second output end is electrically connected to the electric contact part 3011 on the image forming device body 300 side. At this time, the image forming device body 300 can judge whether the processing box 100 meets the expectations based on the electric signal. Therefore, the image forming device body 300 side can directly use the electric contact part 3011 electrically connected to the electrical contact 141 on the storage device 140 to receive the electric signal transmitted by the electric induction component 130, and there is no need to set a separate electric contact part 3011 for receiving the electric signal of the electric induction component 130, thereby saving costs.

[0131] In one possible design, Fig. 9 and Fig.10 As shown, the processing box 100 also includes a signal processing module 220, which is electrically connected to the second output terminal. The signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The electrical signal obtained by the electric induction component 130 can be processed by the signal processing module 220 to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and the circuit in the image forming device can also be protected.

[0132] In a possible design, the second output terminal is also used to electrically connect to the signal processing module 220. When the second output terminal is electrically connected to the signal processing module 220, the signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The signal processing module 220 may not be set on the storage device 140. In this case, when the signal processing module 220 is electrically connected to the second output terminal, the signal processing module 220 processes the electrical signal to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and can also protect the circuit in the image forming device. That is, the processing box itself does not include the signal processing module 220. In order to protect the circuit in the image forming device, the signal processing module 220 is additionally installed.

[0133] In one possible design, Fig.11 As shown, the second output end is electrically connected to the electric contact 141. That is, after receiving the electric signal acquired by the electric induction component 130, the second connecting component 230 transmits the electric signal to the storage device 140 through the second output end, and the electric contact 141 on the substrate 142 of the storage device 140 transmits the electric signal to the image forming device body 300. At this time, the image forming device body 300 can judge whether the processing box 100 meets expectations based on the electric signal.

[0134] Specifically, Fig.11 As shown, the electrical contact 141 is used to electrically connect to the image forming control unit 301 of the image forming apparatus body 300, and can transmit an electrical signal to the image forming control unit 301, and the image forming control unit 301 determines whether the processing box 100 meets expectations based on the electrical signal.

[0135] In a possible design, the processing box 100 further includes a storage device mounting portion, and the second output end protrudes from the outer surface of the storage device mounting portion. When the storage device 140 is mounted on the storage device mounting portion of the processing box 100, since the second output end protrudes from the outer surface of the storage device mounting portion, the storage device 140 can contact with the second output end and have an abutting effect, which can ensure the stability of the connection between the second output end and the storage device 140 and improve the stability of the electrical signal transmission.

[0136] Optionally, the second output end may be a conductive elastic material; or the second output end may be a conductive material, and an elastic member is provided between the second output end and the storage device mounting portion. When the storage device 140 is installed to the storage device mounting portion, the storage device 140 may apply force to the second output end or the elastic member of the conductive elastic material. The rebound force provided by the second output end or the elastic member of the conductive elastic material may press the second output end against the storage device 140, thereby making the connection between the second output end and the storage device 140 tighter and the electrical conduction effect more stable.

[0137] Alternatively, if Figures 12 to 15 As shown, the second connecting component 230 also includes a connecting component and a conductive elastic component 201. The connecting component extends from the waste powder bin 112 of the processing box 100 to the outside of the waste powder bin 112. The end of the connecting component located in the waste powder bin 112 is used to be electrically connected to the inductive component 130, and the end of the connecting component located outside the waste powder bin 112 is used to be electrically connected to the conductive elastic component 201. The conductive elastic component 201 is located outside the waste powder bin 112, and the conductive elastic component 201 is electrically connected to the second output end for outputting the electrical signal obtained by the inductive component 130.

[0138] Furthermore, if Figure 3 , Figures 12 to 15 As shown, the box body 110 includes a waste powder bin 112, and a sealing member 112a is provided on one side of the waste powder bin 112, such as a sealing sponge. The connecting assembly includes a first connecting member 202 and a second connecting member 203. One end of the first connecting member 202 is located between the electric induction component 130 and the sealing sponge in the waste powder bin 112, and the other end of the first connecting member 202 is electrically connected to the second connecting member 203. The second connecting member 203 extends from the waste powder bin 112 to the outside of the waste powder bin 112 and is electrically connected to the conductive elastic member 201. The second connecting member 203 is a U-shaped structure, which can match the end structure of the waste powder bin 112 to improve the installation stability of the second connecting member 203. The conductive elastic member 201 can be a conductive spring, a conductive spring, etc.

[0139] Furthermore, a mounting hole is provided at the end face of the processing box 100, and the conductive elastic member 201 passes through the mounting hole and protrudes from the end face. The storage device mounting portion is located on the end face of the processing box 100, wherein the aperture of the mounting hole gradually increases in the direction approaching the outer surface of the storage device mounting portion, and the conductive elastic member 201 is at least partially a conical structure matching the mounting hole, so as to facilitate the limiting of the conductive elastic member 201.

[0140] In one possible design, Fig.11 , Fig.16 and Fig.17 As shown, the storage device 140 further includes a substrate 142, and an electrical connection terminal 205 is provided on the substrate 142. When the storage device 140 is installed on the storage device installation portion, the electrical connection terminal 205 is electrically connected to the second output terminal. When the storage device 140 is installed on the storage device installation portion on the processing box 100, the electrical connection terminal 205 on the storage device 140 is in direct or indirect contact with the second output terminal, and the second output terminal is electrically connected to the electrical contact 141 through the electrical connection terminal 205, forming a circuit for transmitting the electrical signal obtained by the electrical induction component 130. Specifically, the electrical connection terminal 205 is electrically connected to the electrical contact 141.

[0141] It is understandable that the storage device 140 may not be provided with the electrical connection terminal 205 , but the second output terminal may be electrically connected to the electrical contact 141 through an external wire, a flat cable, etc.

[0142] In one possible design, Fig.16 and Fig.17 As shown, the electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142. The electrical induction component 130 senses the imaging area on the surface of the photosensitive drum 120 and obtains an electrical signal, so generally the electrical signal is transmitted from one side of the processing box 100 to the electrical connection terminal 205 on the storage device 140 via the second connection component 230, and the electrical contact 141 needs to be connected with the image forming device body 300 located outside the processing box 100. Therefore, based on the matching requirements, the electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142, which can conveniently receive the electrical signal generated by the electrical induction component 130 and transmit it to the image forming device body 300, simplify the electrical connection structure, and reduce costs.

[0143] It is understandable that, according to different requirements or design considerations, the electrical connection end 205 and the electrical contact 141 may also be disposed on the same surface of the substrate 142 .

[0144] In addition, the second output end may also be electrically connected to the electrical contact portion 3011 directly or indirectly without passing through the storage device 140 .

[0145] In one possible design, Fig. 9 and Fig.10 As shown, an image forming control unit 301 is provided on the image forming device body 300, and the image forming control unit 301 is electrically connected to the electrical contact portion 3011. The electrical contact 141 is used to electrically connect the electrical contact portion 3011 and thus electrically connect the image forming control unit 301. The storage device 140 has two states. When the storage device 140 is in the first state, communication data can be sent to the image forming control unit 301 through the electrical contact 141; when the storage device 140 is in the second state, communication data is prohibited from being sent to the image forming control unit 301 through the electrical contact 141. By switching the state of the storage device 140 to achieve different functions, when the storage device 140 is switched to the first state, the electrical contact 141 can communicate with the image forming control unit 301, and when the storage device 140 is switched to the second state, the electrical contact 141 is prohibited from communicating with the image forming control unit 301, so that the image forming control unit 301 can recognize and judge the electrical signal.

[0146] In a possible design, when the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state. When the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state, and at this time, the electrical contact 141 and the image formation control unit 301 cannot transmit communication data, which can facilitate the image formation control unit 301 to identify and judge the electrical signal.

[0147] It can be understood that when the electrical contact 141 is electrically connected to the second output terminal, if the electrical contact 141 is configured to be in a high-impedance state, it is actually the MCU circuit portion of the storage device 140 that is configured to be in a high-impedance state, making it impossible to transmit communication data between the MCU and the image forming control unit 301. However, the electrical contact 141 itself, as a conductor or pin, can still transmit the electrical signal of the second output terminal to the electrical contact portion 3011 on the image forming device body 300.

[0148] like Figures 1 to 4 , Fig.11 and Fig.18 As shown, the present application provides a storage device 140 in the seventh aspect, which is installed on the processing box 100, and the processing box 100 can be detachably installed on the image forming device body 300, including an electrical contact 141, and the electrical contact 141 is used to be electrically connected to the electrical contact part 3011 set on the image forming device body 300.

[0149] Further, the storage device 140 also includes a second electrical connection component 240, the second electrical connection component 240 includes an electrical connection end 205, the second electrical connection component 240 is used to be electrically connected to the electric induction component 130 and the electric contact portion 3011 respectively, the electrical connection end 205 is used to obtain an electrical signal of an imaging area on the photosensitive drum 120 of the processing box 100 that can generate an electrostatic latent image when the second electrical connection component 240 is electrically connected to the electric induction component 130, and transmit an electrical signal generated based on the electrical signal to the electric contact portion 3011 when the second electrical connection component 240 is electrically connected to the electric contact portion 3011 for determining whether the processing box 100 meets expectations, wherein the electric induction component 130 is arranged on the processing box 100, and is used to sense the electrical signal on the imaging area.

[0150] The electrical contact 141 of the storage device 140 is used to electrically connect with the electrical contact part 3011 on the image forming device body 300, and the electrical induction component 130 is also electrically connected to the electrical contact part 3011 through the electrical connection end 205 of the second electrical connection component 240 on the storage device 140. At this time, no new contacts are needed on the image forming device body 300 side, that is, the electrical signal of the imaging area of ​​the photosensitive drum 120 sensed by the electrical induction component 130 can be transmitted to the image forming device body 300, which can effectively reduce the manufacturing cost and design difficulty. In addition, the second electrical connection component 240 is also integrated on the storage device 140, with high integration and more reasonable arrangement.

[0151] It can be understood that the number of electrical contacts 141 on the storage device 140 for electrically connecting to the electrical contact portion 3011 of the image forming device body 300 can be set according to needs. For example, there can be one electrical contact 141, in which case the electrical connection end 205 is electrically connected to the electrical contact 141; or, there can be two electrical contacts 141, one electrical contact 141 is a terminal of the storage device 140 itself for data communication with the image forming device body 300, and the other is electrically connected to the electrical connection end 205, and then electrically connected to the two electrical contacts 141 respectively through conductive parts such as wires, conductive tapes, and conductive springs, and simultaneously electrically connected to the electrical contact portion 3011.

[0152] In one possible design, Fig. 9 , Fig.11 and Fig.18 As shown, the storage device 140 further includes a signal processing module 220, which is electrically connected to the electrical connection terminal 205. The signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The electrical signal obtained by the electrical induction component 130 can be processed by the signal processing module 220 to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and the circuit in the image forming device can also be protected.

[0153] In a possible design, the electrical connection end 205 is also used to electrically connect the signal processing module 220. When the electrical connection end 205 is electrically connected to the signal processing module 220, the signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. The signal processing module 220 may not be set on the storage device 140. In this case, when the signal processing module 220 is electrically connected to the electrical connection end 205, the signal processing module 220 processes the electrical signal to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and can also protect the circuit in the image forming device. That is, the processing box itself does not include the signal processing module 220. In order to protect the circuit in the image forming device, the signal processing module 220 is additionally installed.

[0154] In one possible design, Fig.11 As shown, the electrical connection end 205 is electrically connected to the electrical contact 141. At this time, the electrical signal acquired by the electrical induction component 130 is also transmitted to the image forming device body 300 through the electrical contact 141, which can simplify the structure.

[0155] In one possible design, Fig.16 and Fig.17As shown, the electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142. The electrical induction component 130 senses the imaging area on the surface of the photosensitive drum 120 and obtains an electrical signal, so generally the electrical signal is transmitted from one side of the processing box 100 to the electrical connection terminal 205 on the storage device 140 via the second electrical connection component 240, and the electrical contact 141 needs to be connected with the image forming device body 300 located outside the processing box 100. Therefore, based on the matching requirements, the electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142, which can conveniently receive the electrical signal generated by the electrical induction component 130 and transmit it to the image forming device body 300, simplify the electrical connection structure, and reduce costs.

[0156] It is understandable that, according to different requirements or design considerations, the electrical connection end 205 and the electrical contact 141 may also be disposed on the same surface of the substrate 142 .

[0157] In one possible design, Fig.11 and Fig.18 As shown, an image forming control unit 301 is provided on the image forming device body 300, and the image forming control unit 301 is electrically connected to the electrical contact portion 3011. The electrical contact 141 is used to electrically connect the electrical contact portion 3011 and thus electrically connect the image forming control unit 301. The storage device 140 has two states. When the storage device 140 is in the first state, communication data can be sent to the image forming control unit 301 through the electrical contact 141; when the storage device 140 is in the second state, communication data is prohibited from being sent to the image forming control unit 301 through the electrical contact 141. By switching the state of the storage device 140 to achieve different functions, when the storage device 140 is switched to the first state, the electrical contact 141 can communicate with the image forming control unit 301, and when the storage device 140 is switched to the second state, the electrical contact 141 is prohibited from communicating with the image forming control unit 301, so that the image forming control unit 301 can recognize and judge the electrical signal.

[0158] In a possible design, when the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state. When the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state, and at this time, the electrical contact 141 and the image formation control unit 301 cannot transmit communication data, which can facilitate the image formation control unit 301 to identify and judge the electrical signal.

[0159] It can be understood that when the electrical contact 141 is electrically connected to the electrical connection terminal 205, if the electrical contact 141 is configured to be in a high-impedance state, it is actually the MCU circuit portion of the storage device 140 that is configured to be in a high-impedance state, making it impossible to transmit communication data between the MCU and the image forming control unit 301. However, the electrical contact 141 itself, as a conductor or pin, can still transmit the electrical signal of the electrical connection terminal 205 to the electrical contact portion 3011 on the image forming device body 300.

[0160] like Figures 1 to 4 , Fig.11 and Fig.18 As shown, the present application provides a processing box 100 in the eighth aspect, the processing box 100 includes a box body 110, a photosensitive drum 120 and an inductive component 130, the photosensitive drum 120 is rotatably arranged on the box body 110, the photosensitive drum 120 is provided with an imaging area for generating an electrostatic latent image, and the inductive component 130 is used to detect the electrical signal on the imaging area.

[0161] Furthermore, the process box 100 further includes the storage device 140 as described above, and the storage device 140 is electrically connected to the inductive component 130 .

[0162] In the above-mentioned process cartridge 100, the electrical contact 141 of the storage device 140 is used to be electrically connected to the electrical contact portion 3011 on the image forming device body 300, and the electrical induction component 130 is also electrically connected to the electrical contact portion 3011 through the electrical connection end 205 of the second electrical connection component 240 on the storage device 140. At this time, no new contacts are needed on the image forming device body 300 side, that is, the electrical signal of the imaging area of ​​the photosensitive drum 120 sensed by the electrical induction component 130 can be transmitted to the image forming device body 300, which can effectively reduce the manufacturing cost and design difficulty. In addition, the second electrical connection component 240 is also integrated on the storage device 140, with high integration and more reasonable arrangement.

[0163] In one possible design, Fig.11 and Fig.18 As shown, the processing box 100 further includes a third electrical connection component 250 , and the inductive component 130 is electrically connected to the electrical connection terminal 205 via the third electrical connection component 250 .

[0164] Of course, the second electrical connection component 240 may also be directly electrically connected to the electrical induction component 130 .

[0165] In a possible design, the box body 110 further includes a storage device mounting portion, and the third electrical connection component 250 at least partially protrudes from the outer surface of the storage device mounting portion. When the storage device 140 is mounted on the storage device mounting portion of the processing box 100, since the third electrical connection component 250 protrudes from the outer surface of the storage device mounting portion, the storage device 140 can contact the third electrical connection component 250 and have an abutting effect, which can ensure the stability of the connection between the third electrical connection component 250 and the storage device 140, and improve the stability of the electrical signal transmission.

[0166] Optionally, the third electrical connection component 250 has a delivery end 204 for electrically connecting to the electrical connection end 205, the delivery end 204 at least partially protrudes from the outer surface of the storage device mounting portion, and the delivery end 204 can be a conductive elastic material; or the delivery end 204 is a conductive material, and an elastic member is provided between the delivery end 204 and the storage device mounting portion. When the storage device 140 is installed in the storage device mounting portion, the storage device 140 can apply force to the delivery end 204 or the elastic member made of the conductive elastic material, and the resilience provided by the delivery end 204 or the elastic member made of the conductive elastic material can make the delivery end 204 and the storage device 140 press against each other, so that the connection between the delivery end 204 and the storage device 140 is tighter and the electrical conduction effect is more stable.

[0167] Alternatively, if Figures 12 to 15 As shown, the third electrical connection component 250 also includes a connecting component and a conductive elastic component 201. The connecting component extends from the waste powder bin 112 of the processing box 100 to the outside of the waste powder bin 112. The end of the connecting component located in the waste powder bin 112 is used to be electrically connected to the electric induction component 130, and the end of the connecting component located outside the waste powder bin 112 is used to be electrically connected to the conductive elastic component 201. The conductive elastic component 201 is located outside the waste powder bin 112, and the conductive elastic component 201 is electrically connected to the electrical connection end 205 for outputting the electrical signal obtained by the electric induction component 130.

[0168] Furthermore, if Figure 3 , Figures 12 to 15 As shown, the box body 110 includes a waste powder bin 112, and a sealing member 112a is provided on one side of the waste powder bin 112, such as a sealing sponge. The connecting assembly includes a first connecting member 202 and a second connecting member 203. One end of the first connecting member 202 is located between the electric induction component 130 and the sealing sponge in the waste powder bin 112, and the other end of the first connecting member 202 is electrically connected to the second connecting member 203. The second connecting member 203 extends from the waste powder bin 112 to the outside of the waste powder bin 112 and is electrically connected to the conductive elastic member 201. The second connecting member 203 is a U-shaped structure, which can match the end structure of the waste powder bin 112 to improve the installation stability of the second connecting member 203. The conductive elastic member 201 can be a conductive spring, a conductive spring, etc.

[0169] Furthermore, a mounting hole is provided at the end face of the processing box 100, and the conductive elastic member 201 passes through the mounting hole and protrudes from the end face. The storage device mounting portion is located on the end face of the processing box 100, wherein the aperture of the mounting hole gradually increases in the direction approaching the outer surface of the storage device mounting portion, and the conductive elastic member 201 is at least partially a conical structure matching the mounting hole, so as to facilitate the limiting of the conductive elastic member 201.

[0170] In an eighth aspect, the present application provides an image forming device, comprising the process box 100 as described above.

[0171] like Figures 1 to 3 , Fig.19 and Fig. 20 As shown, in the ninth aspect, the present application provides an adapter 260, which is installed on the processing box 100, and the processing box 100 is detachably set on the image forming device body 300, including a receiving end 206 and a conveying end 204 electrically connected to the receiving end 206, the receiving end 206 is used to electrically connect to the electric induction component 130, so as to obtain the electric signal on the imaging area of ​​the photosensitive drum 120 in the processing box 100 that can generate an electrostatic latent image sensed by the electric induction component 130, the conveying end 204 is used to electrically connect to the electric contact part 3011 set on the image forming device body 300, the electric contact part 3011 is used to connect to the electric contact 141 on the storage device 140 installed on the processing box 100, the conveying end 204 is used to obtain the electric signal, and transmit the signal generated based on the electric signal to the electric contact part 3011 for determining whether the processing box 100 meets the expectations.

[0172] The above-mentioned adapter 260 can transmit the electric signal sensed by the electric induction component 130 to the electric contact portion 3011, and the electric contact portion 3011 is also electrically connected to the electric contact 141 on the storage device 140 on the processing box 100, so that the electric contact portion 3011 set on the image forming device body 300 can communicate data with the electric contact 141 of the storage device 140, and can also receive the electric signal sensed by the electric induction component 130. By setting the above-mentioned adapter 260, there is no need to set a new terminal on the image forming device body 300 side, which can effectively reduce the design and manufacturing difficulty of the image forming device body 300 side.

[0173] In one possible design, Fig. 20As shown, the delivery end 204 is electrically connected to the electric contact 141. That is, after receiving the electric signal acquired by the electric induction component 130, the receiving end 206 transmits the electric signal to the electric contact 141 of the storage device 140 through the delivery end 204, and the electric contact 141 on the storage device 140 transmits the electric signal to the image forming device body 300. At this time, the image forming device body 300 can judge whether the processing box 100 meets expectations based on the electric signal. At this time, the electric signal acquired by the electric induction component 130 is also transmitted to the electric contact part 3011 of the image forming device body 300 through the electric contact 141, which can simplify the assembly structure.

[0174] In one possible design, Fig. 20 As shown, the storage device 140 includes a substrate 142, on which an electrical connection terminal 205 is disposed, and the delivery terminal 204 is electrically connected to the electrical connection terminal 205. At this time, the adapter 260 is electrically connected to the image forming apparatus body 300 through the storage device 140.

[0175] It is understandable that the electrical connection end 205 and the delivery end 204 may also be the same part of the adapter 260 , that is, the delivery end 204 is directly disposed on the storage device 140 .

[0176] In one possible design, Fig. 9 and Fig.19 As shown, the adapter 260 includes a signal processing module 220, which is electrically connected to the delivery end 204. The signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal, and the processed signal is used to determine whether the processing box 100 meets expectations. At this time, when the electric induction unit senses the electric signal, the electric signal can be transmitted to the signal processing module 220 through the delivery end 204, and the signal processing module 220 processes the electric signal to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and can also protect the circuit in the image forming device.

[0177] In one possible design, Fig. 9 and Fig.19 As shown, the receiving end 206 is also used to electrically connect to the signal processing module 220. The signal processing module 220 is used to process the signal input to the signal processing module 220 to obtain a processed signal. The processed signal is used to determine whether the processing box 100 meets expectations. The signal processing module 220 can also be installed later. When the signal processing module 220 is electrically connected to the receiving end 206, the signal processing module 220 processes the electrical signal to obtain a signal that is more convenient for the image forming device body 300 to process or identify, and can also protect the circuit in the image forming device.

[0178] In the tenth aspect, the present application provides a component, including an inductive component 130 and an adapter 260 as described above, wherein the inductive component 130 is electrically connected to the receiving end 206, wherein the inductive component 130 is used to sense the electrical signal on the imaging area of ​​the photosensitive drum 120 in the processing box 100 that can generate an electrostatic latent image.

[0179] The above-mentioned components can transmit the electric signal sensed by the electric induction component 130 to the electric contact portion 3011, and the electric contact portion 3011 is also electrically connected to the electric contact 141 on the storage device 140 on the processing box 100, so that the electric contact portion 3011 set on the image forming device body 300 can communicate data with the electric contact 141 of the storage device 140, and can also receive the electric signal sensed by the electric induction component 130. By setting the above-mentioned adapter 260, there is no need to set a new terminal on the image forming device body 300 side, which can effectively reduce the design and manufacturing difficulty of the image forming device body 300 side.

[0180] like Figures 1 to 3 , Fig.19 and Fig. 20 As shown, the present application provides a processing box 100 in the eleventh aspect, including a box body 110, a photosensitive drum 120 and an adapter setting area. The photosensitive drum 120 can be rotatably arranged on the box body 110. The photosensitive drum 120 is provided with an imaging area that can generate an electrostatic latent image. The adapter setting area is used to set the adapter 260 as mentioned above.

[0181] The above-mentioned processing box 100 can transmit the electric signal sensed by the electric induction component 130 to the electric contact portion 3011, and the electric contact portion 3011 is also electrically connected to the electric contact 141 on the storage device 140 on the processing box 100, so that the electric contact portion 3011 set on the image forming device body 300 can communicate data with the electric contact 141 of the storage device 140, and can also receive the electric signal sensed by the electric induction component 130. By setting the above-mentioned adapter 260, there is no need to set a new terminal on the image forming device body 300 side, which can effectively reduce the design and manufacturing difficulty of the image forming device body 300 side.

[0182] In one possible design, Fig.19 and Fig. 20As shown, the process cartridge 100 further includes a storage device 140, the storage device 140 includes an electrical contact 141, and the delivery end 204 is electrically connected to the electrical contact 141. The electrical signal is transmitted from the delivery end 204 to the electrical contact 141 of the storage device 140, and the electrical contact 141 on the storage device 140 transmits the electrical signal to the image forming device body 300, and the image forming device body 300 can judge whether the process cartridge 100 meets expectations based on the electrical signal. At this time, the electrical signal obtained by the electrical induction component 130 is also transmitted to the electrical contact portion 3011 of the image forming device body 300 through the electrical contact 141, which can simplify the assembly structure.

[0183] In one possible design, Fig.19 As shown, an image forming control unit 301 is provided on the image forming device body 300, and the image forming control unit 301 is electrically connected to the electrical contact portion 3011. The electrical contact 141 is used to electrically connect the electrical contact portion 3011 and thus electrically connect the image forming control unit 301. The storage device 140 has two states. When the storage device 140 is in the first state, communication data can be sent to the image forming control unit 301 through the electrical contact 141; when the storage device 140 is in the second state, communication data is prohibited from being sent to the image forming control unit 301 through the electrical contact 141. By switching the state of the storage device 140 to achieve different functions, when the storage device 140 is switched to the first state, the electrical contact 141 can communicate with the image forming control unit 301, and when the storage device 140 is switched to the second state, the electrical contact 141 is prohibited from communicating with the image forming control unit 301, so that the image forming control unit 301 can recognize and judge the electrical signal.

[0184] In a possible design, when the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state. When the storage device 140 is in the second state, the electrical contact 141 is configured to be in a high impedance state, and at this time, the electrical contact 141 and the image formation control unit 301 cannot transmit communication data, which can facilitate the image formation control unit 301 to identify and judge the electrical signal.

[0185] It can be understood that when the electrical contact 141 is electrically connected to the delivery end 204, if the electrical contact 141 is configured to be in a high-impedance state, it is actually the MCU circuit portion of the storage device 140 that is configured to be in a high-impedance state, making it impossible to transmit communication data between the MCU and the image forming control unit 301. However, the electrical contact 141 itself, as a conductor or pin, can still transmit the electrical signal of the delivery end 204 to the electrical contact portion 3011 on the image forming device body 300.

[0186] In a possible design, the box body 110 further includes a storage device mounting portion, the storage device mounting portion is used to mount the storage device 140, and the delivery end 204 at least partially protrudes from the outer surface of the storage device mounting portion. When the storage device 140 is mounted on the storage device mounting portion of the processing box 100, since the delivery end 204 protrudes from the outer surface of the storage device mounting portion, the storage device 140 can contact the delivery end 204 and have an abutment effect, which can ensure the stability of the connection between the delivery end 204 and the storage device 140, and improve the stability of electrical signal transmission.

[0187] In one possible design, Fig. 20 As shown, the storage device 140 further includes a substrate 142, and an electrical connection terminal 205 is further provided on the substrate 142. When the storage device 140 is mounted on the storage device mounting portion, the electrical connection terminal 205 is electrically connected to the delivery terminal 204. When the storage device 140 is mounted on the storage device mounting portion on the processing box 100, the electrical connection terminal 205 on the storage device 140 is in direct or indirect contact with the delivery terminal 204, and the delivery terminal 204 is electrically connected to the electrical contact 141 through the electrical connection terminal 205, forming a circuit for transmitting the electrical signal obtained by the electrical induction component 130. Specifically, the electrical connection terminal 205 is electrically connected to the electrical contact 141.

[0188] It is understandable that the storage device 140 may not be provided with the electrical connection terminal 205 , but the transmission terminal 204 may be electrically connected to the electrical contact 141 through an external wire, a flat cable, etc.

[0189] In one possible design, Fig.16 and Fig.17 As shown, the electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142. The electrical connection terminal 205 and the electrical contact 141 are respectively arranged on different surfaces of the substrate 142, so that the electrical signal generated by the electrical induction component 130 can be conveniently received and transmitted to the image forming device body 300, simplifying the electrical connection structure and reducing the cost.

[0190] It is understandable that, according to different requirements or design considerations, the electrical connection end 205 and the electrical contact 141 may also be disposed on the same surface of the substrate 142 .

[0191] In a possible design, the processing box 100 includes a connection component installation area, and the connection component installation area is used to install the third connection component. When the third connection component is installed in the connection component installation area, the third connection component is electrically connected to the electric induction component 130. The third connection component includes a third output end, and the third output end is used to electrically connect to the image forming device body 300 so as to transmit to the image forming device body 300 an electric signal used to determine whether the processing box 100 meets expectations based on the sensing result of the electric induction component 130. By installing the third connection component in the connection component installation area on the processing box 100 and electrically connecting the third connection component to the electric induction component 130, the processing box 100 can transmit the electric signal obtained by the electric induction component 130 through the third connection component. After the processing box 100 is installed in the image forming device body 300, the third output end of the third connection component can transmit the electric signal obtained by the electric induction component 130 to the image forming device body 300, so that the image forming device body 300 determines whether the processing box 100 meets expectations based on the electric signal.

[0192] In fact, when the third connecting component is installed in the connecting component installation area, the third connecting component needs to meet at least the following installation requirements:

[0193] The third connecting component is electrically connected to the electric induction component 130; and

[0194] The position of the third output terminal on the processing box 100 needs to correspond to an electrical contact portion on the image forming apparatus body 300, so that when the processing box 100 is installed in the image forming apparatus body 300, the third output terminal can contact the electrical contact portion to form an electrical connection.

[0195] It is understandable that adding a third connecting component to the processing box 100 will increase the assembly process. Based on cost or feasibility considerations, after the other parts of the processing box 100 are assembled, a connecting component installation area can be reserved on the processing box 100, and then the third connecting component can be installed in the connecting component installation area.

[0196] Specifically, an exposed area, namely a connecting component installation area, is provided on the processing box 100, and the size of the area matches the size of the inductive component 130; or the connecting component installation area is provided inside the processing box 100, which can be used to install the inductive component 130 or give a prompt that the inductive component 130 can be installed.

[0197] Further, the processing box 100 is provided with a depression or a protrusion at the connecting component installation area; or the processing box 100 is provided with a concave edge or a convex edge surrounding the connecting component installation area; or the processing box 100 is provided with an identification portion at the connecting component installation area, and the identification portion can be text, symbols, patterns, etc., which can indicate the specific installation location.

[0198] In addition, the processing box 100 is a detachable structure, and some components of the processing box 100 can be removed to facilitate the installation of the third connecting component.

[0199] In one possible design, a storage device 140 and a connecting component installation area are installed on the processing box 100, and the connecting component installation area is used to install a fourth connecting component, and the fourth connecting component includes a fourth output terminal. The storage device 140 includes a substrate 142 and an electrical contact 141 electrically connected to the substrate 142, and the electrical contact 141 is used to electrically connect to the electrical contact portion 3011 provided on the image forming device body 300. When the fourth connecting component is installed in the connecting component installation area, the fourth connecting component is electrically connected to the electric induction component 130, and the fourth output terminal is electrically connected to the electrical contact 141. The fourth connecting component can be installed in the connecting component installation area on the processing box 100, and the fourth connecting component can be electrically connected to the inductive component 130, so that the processing box 100 can transmit the electric signal obtained by the inductive component 130 through the fourth connecting component, and the fourth output end of the fourth connecting component is electrically connected to the electric contact part 3011. After the processing box 100 is installed in the image forming device body 300, the electric signal obtained by the inductive component 130 can be transmitted to the image forming device body 300 through the electrically connected electric contact part 3011, so that the image forming device body 300 can judge whether the processing box 100 meets expectations based on the electric signal.

[0200] In fact, when the fourth connecting component is installed in the connecting component installation area, the fourth connecting component needs to meet at least the following installation requirements:

[0201] The fourth connecting component is electrically connected to the inductive component 130; and

[0202] The fourth output terminal is electrically connected to the electrical contact portion 3011 .

[0203] It is understandable that adding a fourth connecting component to the processing box 100 will increase the assembly process. Based on cost or feasibility considerations, after the other parts of the processing box 100 are assembled, a connecting component installation area can be reserved on the processing box 100, and then the fourth connecting component can be installed in the connecting component installation area.

[0204] Specifically, an exposed area, namely a connecting component installation area, is provided on the processing box 100, and the size of the area matches the size of the inductive component 130; or the connecting component installation area is provided inside the processing box 100, which can be used to install the inductive component 130 or give a prompt that the inductive component 130 can be installed.

[0205] Further, the processing box 100 is provided with a depression or a protrusion at the connecting component installation area; or the processing box 100 is provided with a concave edge or a convex edge surrounding the connecting component installation area; or the processing box 100 is provided with an identification portion at the connecting component installation area, and the identification portion can be text, symbols, patterns, etc., which can indicate the specific installation location.

[0206] In addition, the processing box 100 is a detachable structure, and some parts of the processing box 100 can be removed to facilitate the installation of the fourth connecting part.

[0207] Determine whether the process cartridge meets expectations based on electrical signals

[0208] A twelfth aspect of the present application provides a detection method, which is applied to an image forming device, comprising the following steps:

[0209] issuing an image formation instruction including a preset test image;

[0210] Based on the image forming instruction, acquiring a second electrical signal generated based on a first electrical signal generated on the surface of the photosensitive drum 120 in the process cartridge 100;

[0211] Determining whether the second electrical signal corresponds to a preset test image;

[0212] Based on the judgment result, it is determined whether the process cartridge 100 is as expected.

[0213] In the above-mentioned test method, based on the image formation instruction issued, an electrostatic latent image corresponding to a preset test image can be formed on the surface of the photosensitive drum 120. At this time, a first electrical signal can be obtained based on the imaging area on the surface of the photosensitive drum 120. The first electrical signal can generate a second electrical signal after transmission or processing. Then, based on whether the information of the second electrical signal can correspond to the preset test image, it can be determined whether the processing box 100 meets expectations.

[0214] Optionally, the above-mentioned detection method can be applied to the above-mentioned image forming device. During the test, the image forming device has an inductive component 130, which is a part of the processing box 100; or the inductive component 130 is installed on the processing box 100; or it is separate from the processing box 100. The inductive component 130 can sense the imaging area on the surface of the photosensitive drum 120 to generate a first electrical signal.

[0215] In one possible design, determining whether the second electrical signal corresponds to a preset test image includes:

[0216] The second electrical signal includes a plurality of voltage values; determining the number of voltage values ​​exceeding a first preset threshold value among the plurality of voltage values;

[0217] Comparing the quantity information with a second preset threshold value, thereby generating a comparison result;

[0218] When the comparison result is inconsistent, the judgment result is that the second electrical signal does not correspond to the preset test image.

[0219] After obtaining the second electrical signal, multiple voltage values ​​in the second electrical signal can be compared with the first preset threshold, and the number of voltage values ​​exceeding the first preset threshold can be counted to obtain quantity information, and the quantity information can be compared with the second preset threshold. When the comparison result is inconsistent, the second electrical signal does not correspond to the preset test image.

[0220] It can be understood that when the quantity information is consistent with the comparison result of the second preset threshold value, it is determined that the processing box 100 meets expectations; or further judgment is performed.

[0221] It can be understood that the second preset threshold value can be a point value or a range value. When the second preset threshold value is a range value, the comparison result is consistent if the quantity information falls within the above range value.

[0222] Optionally, after the imaging area of ​​the photosensitive drum is exposed, if the exposure intensity for different areas of the imaging area is different, different areas with potential differences may be formed on the imaging area.

[0223] It is understandable that voltage values ​​will be continuously obtained based on the test image. For example, as the photosensitive drum 120 rotates after exposure, when the inductive component 130 changes from being relative to one area on the imaging area to being relative to another area with a different potential on the imaging area, that is, when the inductive component 130 passes through the junction of two areas with different potentials on the imaging area, the obtained voltage value will increase or decrease.

[0224] It is understandable that, based on different comparison methods, the second preset threshold value can adopt different forms of numerical values: for example, when comparing the quantity information and the second preset threshold value, the number of multiple voltage values ​​of the second electrical signal that exceeds the first preset threshold value can be directly compared with the second preset threshold value; or the multiple voltage values ​​exceeding the first preset threshold value obtained when the electric induction component 130 passes through the junction of two areas with different potentials on the imaging area are regarded as a data set, and the number of data sets in the second electrical signal obtained based on the test image is counted, and then the number of data sets is compared with the second preset threshold value. In fact, the number of data sets has a corresponding relationship with the number of electrostatic latent image areas on the imaging area.

[0225] In one possible design, Fig.21As shown, the test image has four dark area blocks arranged at intervals, and the rest are light areas. Specifically, when the exposure operation is performed based on the test image, a first electrostatic latent image area corresponding to the dark area in the test image and a second electrostatic latent image area corresponding to the light area are formed on the photosensitive drum 120. As the photosensitive drum 120 rotates, the electric induction component 130 passes through the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, and the second electrostatic latent image area in sequence, and the corresponding electric induction components pass through the The electric signals sensed by the electric induction component 130 correspond to the aforementioned electrostatic latent image areas respectively. When the electric induction component 130 passes through the first electrostatic latent image area or the second electrostatic latent image, the electric induction component 130 senses a first voltage; when the electric induction component 130 passes through the boundary from the first electrostatic latent image area to the second electrostatic latent image area, the electric induction component 130 senses a second voltage; when the electric induction component 130 passes through the boundary from the second electrostatic latent image area to the first electrostatic latent image area, the electric induction component 130 senses a third voltage, wherein the second voltage and the third voltage have different polarities; the first voltage, the second voltage and the third voltage are signals directly sensed by the electric induction component.

[0226] In order to more accurately determine whether the processing box 100 meets expectations, the image forming device is provided with a detection circuit for detecting the signal sensed by the electric induction component 130. Since the detection circuit itself has a certain inherent signal, the first electrical signal obtained by the detection voltage will include the aforementioned first voltage, second voltage, third voltage and inherent signal. Specifically, the inherent signal can be superimposed on the first voltage, second voltage and third voltage respectively. In addition, in order to ensure the detection accuracy, the detection circuit will detect the electrical signal sensed by the electric induction component multiple times, so the first electrical signal will include multiple first voltages, multiple second voltages and multiple third voltages.

[0227] In the actual detection process, the image forming device also processes the detected first electrical signal to obtain a second electrical signal. Specifically, the second electrical signal can be obtained by setting the signal processing module 220 to perform voltage division processing, and / or voltage stabilization processing, and / or rectification processing on the first electrical signal. For example, the signal processing module 220 can be used to perform rectification processing on the first electrical signal to remove the third voltage contained in the first electrical signal.

[0228] Specifically, Fig. 22 As shown, after the photosensitive drum 120 is exposed, the electric induction component 130 can sequentially face and pass through each electrostatic latent image area on the photosensitive drum 120, for example, when ... Fig.21When the image forming instruction of the test image shown in the figure is executed, a first electrostatic latent image area corresponding to the black area in the test image and a second electrostatic latent image area corresponding to the white area are formed on the photosensitive drum 120. As the photosensitive drum 120 rotates, the electric induction component 130 passes through the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, and the second electrostatic latent image area in sequence. When the electric induction component 130 is initially opposite to the second electrostatic latent image area, the electric induction component 130 senses a plurality of first voltages, wherein the first voltage is a stable value or has a small fluctuation. At the same time, the first voltage is superimposed with an inherent signal of the detection circuit, so as to form a signal as shown in FIG. Fig. 22 The curve at the beginning of Fig. 22 The a segment curve in .

[0229] Then the electric induction component 130 passes through the boundary between the second electrostatic latent image area and the first electrostatic latent image area. At this time, the electric induction component senses a plurality of second voltages, and the second voltage is greater than the first voltage. As the electric induction component 130 changes from being opposite to the second electrostatic latent image area to being opposite to the first electrostatic latent image area, the second voltage increases first and then decreases. At the same time, the inherent signal of the detection circuit is superimposed on the second voltage, forming a signal as shown in FIG. Fig. 22 The first peak in Fig. 22 The b-segment curve in .

[0230] Then, the electric induction component 130 passes through the boundary between the first electrostatic latent image region and the second electrostatic latent image region. At this time, the electric induction component senses a third voltage, which is less than the first voltage. As the electric induction component 130 changes from being opposite to the first electrostatic latent image region to being opposite to the second electrostatic latent image region, the third voltage decreases first and then increases. However, by setting the signal processing module 220 to process the first electrical signal, the third voltage can be removed and the inherent signal of the detection circuit can be superimposed. Fig. 22 A curve similar to the first voltage is formed in Fig. 22 The c-segment curve in .

[0231] Then the electric induction component 130 will pass through the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, the second electrostatic latent image area, the first electrostatic latent image area, and the second electrostatic latent image area in sequence. Fig. 22 A curve similar to the first peak and its two sides is formed.

[0232] based on Fig. 22When determining whether the second electrical signal corresponds to the preset test image, first determine whether it has a voltage value exceeding the first preset threshold, and multiple consecutive voltage values ​​exceeding the first preset threshold can be regarded as a data set, and then determine whether the number of data sets in the second electrical signal is the same as the second preset threshold, where the number of data sets in the second electrical signal is Fig. 22 The second preset value may be the number of black areas in the test image. If they are inconsistent, the judgment result is that the second electrical signal does not correspond to the preset test image.

[0233] Of course, the number of black areas in the test image can also be set to other numbers, and other colors besides black can also be used; or two adjacent areas in the test image can also use the same color with different concentrations, as long as there is a potential difference between different areas when an electrostatic latent image is formed on the photosensitive drum based on the test image.

[0234] In one possible design, determining whether the second electrical signal corresponds to a preset test image includes:

[0235] When the comparison result between the quantity information and the second preset threshold value is consistent, it is further determined whether the generation time of the voltage value exceeding the first preset threshold value in the second electrical signal meets the requirements compared with the preset timing starting point. When the generation time of the voltage value exceeding the first preset threshold value meets the requirements, it is determined that the second electrical signal corresponds to the preset test profile; and / or

[0236] When the comparison result of the quantity information is consistent with the second preset threshold, it is further determined whether the generation position information of the voltage value exceeding the first preset threshold in the second electrical signal compared to the preset position starting point meets the requirements. When the generation position information of the voltage value exceeding the first preset threshold meets the requirements, it is determined that the second electrical signal corresponds to the preset test image.

[0237] The preset timing starting point may be the time point at which the image formation instruction including the preset test image is issued or the time point plus a certain time;

[0238] Or it may be the time point when the optical scanning unit emits the light beam, or a certain time point after the light beam is emitted, or a certain time point before the light beam is emitted.

[0239] Optionally, after a certain time point is taken as the preset timing starting point, when a voltage value exceeding the first preset threshold value is obtained in the second electrical signal, the time difference between the voltage value and the preset timing starting point can be determined as the generation time of the voltage value, for example Fig. 22As shown in the figure, the horizontal axis of the coordinate system is the serial number of the obtained voltage value, and the time interval for obtaining the voltage value is the unit time interval. If point d of the voltage value curve is used as the preset timing starting point, and at the same time, there is a voltage value exceeding the first preset threshold value at point e, the generation time of the voltage value e compared to the preset timing starting point can be obtained based on the difference between the horizontal coordinates of point e and point d multiplied by the unit time interval. Of course, the above example is to illustrate the relationship between the preset timing starting point and the time point when the voltage value exceeding the first preset threshold value in the second electrical signal is obtained, and it does not mean that the time difference between the acquisition and the preset timing starting point is only the method of the above example. In fact, if the preset timing starting point is the time point when the voltage value is obtained a certain time, when the voltage value exceeding the first preset threshold value in the second electrical signal is obtained, the generation time of the aforementioned voltage value can also be obtained based on the time difference between the current time and the preset timing starting point.

[0240] Among them, the preset position starting point can be a preset timing starting point, and then the voltage value can be continuously collected multiple times based on the unit time interval to form a voltage value sequence. The voltage values ​​collected in sequence have corresponding serial numbers. For example, the serial number of the voltage value collected after a unit time interval after the preset position starting point is 1, then when a voltage value exceeding the first preset threshold is obtained, the serial number of this voltage value can also be obtained at the same time. This serial number is the generated position information of this voltage value in the voltage value sequence, which can represent the position of this voltage value in the above voltage value sequence.

[0241] Alternatively, if Fig. 22 As shown, the horizontal axis of the coordinate system in the figure is the serial number of the voltage value, and the time interval for obtaining the voltage value is the unit time interval. If point f of the voltage value curve is used as the starting point of the preset position, and at the same time, there is a voltage value exceeding the first preset threshold at point g, the generated position information of this voltage value compared with the starting point of the preset position can be obtained according to the difference between the horizontal coordinates of point g and point f, and the generated position information can be judged. Among them, point e and point g in the voltage value curve can be the same point or different points, and point f and point d can be the same point or different points.

[0242] When the comparison result of the quantity information and the second preset threshold value is consistent, further judgment can be made. Based on the attribute of the voltage value having the generation time, the generation time of the voltage value exceeding the first preset threshold value can be compared with the preset test image. If the generation time of the voltage value exceeding the first preset threshold value meets the requirement, it is judged that the second electrical signal corresponds to the preset test image. At this time, the accuracy of the judgment can be improved and the error can be reduced.

[0243] In addition, based on the fact that the generated multiple voltage values ​​have generation position information with each other, the generation position information of the voltage value exceeding the first preset threshold can be compared with the preset test image. If the generation position information of the voltage value exceeding the first preset threshold meets the requirements, it is judged that the second electrical signal corresponds to the preset test image, which can also improve the accuracy of the judgment and reduce errors.

[0244] It is understandable that when further determination is made, the determination may be based on at least one of the generation time of the voltage value and the generation location information. Of course, if the determination is made based on both the generation time of the voltage value and the generation location information, the determination accuracy is higher.

[0245] In one possible design, before determining the number of voltage values ​​exceeding a first preset threshold value among a plurality of voltage values, the detection method includes:

[0246] It is determined that the generation position information of the first voltage value exceeding the first preset threshold value in the second electrical signal meets the requirements compared with the preset position starting point.

[0247] That is, before starting to determine whether the quantity information of voltage values ​​exceeding the first preset threshold among multiple voltage values ​​meets expectations, first check whether the generation position information of the first voltage value exceeding the first preset threshold meets the requirements. If it does not meet the requirements, it can be directly determined that the second electrical signal does not correspond to the preset test image, thereby improving the efficiency of judgment.

[0248] A thirteenth aspect of the present application provides an image forming device, comprising:

[0249] The image forming control unit 301 is used to execute the steps of the above-mentioned detection method.

[0250] The above-mentioned image forming device can issue image forming instructions through the image forming control unit 301, so that an electrostatic latent image corresponding to a preset test image can be formed on the surface of the photosensitive drum 120. At this time, a first electrical signal can be obtained based on the imaging area on the surface of the photosensitive drum 120. The first electrical signal can generate a second electrical signal after transmission or processing. The image forming control unit 301 can determine whether the processing box 100 meets expectations based on whether the information of the second electrical signal can correspond to the preset test image.

[0251] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
