Description

Technical Field

[0001] This invention relates to the field of image forming technology, and in particular to a detection device, a conductive component, a processing box, a processing box assembly, an image forming apparatus, and a detection method. Background Technology

[0002] Image forming apparatuses are common devices used in work and daily life, including printers, copiers, fax machines, and many other forms. Image forming apparatuses typically include monochrome and color image forming apparatuses. Color image forming apparatuses usually consist of a main body and multiple processing cartridges housed within the main body, each cartridge containing toner of a specific color.

[0003] The color image forming apparatus has four processing boxes for holding toners of four basic colors: black, cyan, yellow, and magenta. By superimposing these four basic colors, a rich variety of colors are obtained, thus forming a color image. The main body of the image forming apparatus has a drawer for holding the four processing boxes, and the drawer has four slots for holding the four processing boxes.

[0004] In existing technology, the positioning of the processing boxes within the main body relies on drawer positioning. When the drawer's position is inaccurate, the processing boxes will also be inaccurately positioned. When users replace or inspect the processing boxes, they may pull or push the drawer multiple times. After the user pulls or pushes the drawer repeatedly and then puts it back into the main body, the drawer's position may change, potentially leading to inaccurate drawer positioning, and consequently, inaccurate positioning of the four processing boxes.

[0005] However, during the use of the image forming apparatus, the quality of the printed image will decrease after the drawer is pushed or pulled multiple times. There is an urgent need for a solution that can count the number of times the drawer is pushed or pulled in order to determine in a timely manner whether line color registration correction is required.

[0089] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0090] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0091] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0092] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0093] In the above description, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0094] In existing technology, the positioning of the processing cartridges within the main body relies on drawer positioning. When the drawer's position is inaccurate, the processing cartridges will also be inaccurately positioned. When users replace or inspect the processing cartridges, they often pull or push the drawer multiple times. After these repeated pulls and pushes, the drawer's position may change, potentially leading to inaccurate drawer positioning and consequently, inaccurate positioning of the four processing cartridges. However, during use, repeated drawer pushing or pulling during image forming apparatus operation can prevent timely color registration correction, potentially causing inaccurate toner layering in the four processing cartridges. This results in reduced print quality. Therefore, a solution is urgently needed to statistically analyze the number of drawer pushes and pulls to promptly determine if line color registration correction is necessary.

[0095] To address the aforementioned problems, the present invention provides a detection device, a conductive component, a processing box, a processing box assembly, an image forming apparatus, and a detection method. By generating a detection signal indicating that a moving component is pushed forward and / or pulled out relative to the frame of the main body of the image forming apparatus, and by counting the number of times the moving component is pushed forward and / or pulled out relative to the frame using the detection signal, it is possible to determine whether color registration correction needs to be performed based on the number of times the moving component is pushed or pulled, thereby enabling timely color registration correction and improving the quality of the printed image from the image forming apparatus.

[0096] The detection device, conductive component, processing box, processing box assembly, image forming apparatus, and detection method provided in the embodiments of the present invention will be described in detail below with reference to specific embodiments.

[0097] Figure 1 A schematic diagram of an image forming apparatus provided in an embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram of the structure of the image forming apparatus in the diagram; Figure 3 for Figure 1 A schematic diagram showing a conductive spring sheet mounted on the main body of the image forming apparatus. Figure 4 for Figure 1A schematic diagram of the operation of the image forming apparatus in the diagram; Figure 5 A schematic diagram of a first type of processing box placed in a moving component according to an embodiment of the present invention; Figure 6 for Figure 5 Schematic diagram of conductive components and storage device in the image; Figure 7 for Figure 1 The image forming control unit obtains the voltage data map of the first conductive spring.

[0098] like Figure 1 As shown, an embodiment of the present invention provides an image forming apparatus, including a processing box 1, a main body 2, an image forming control unit 3, and a power supply unit 4.

[0099] Among them, such as Figures 1 to 4 As shown, the main body 2 includes a frame 20, a moving part 21, a conductive spring 22, and a front cover 23. The side where the front cover 23 of the image forming apparatus is located is the front side of the image forming apparatus; the side opposite to the front side of the image forming apparatus is the rear side of the image forming apparatus; in the direction of gravity of the image forming apparatus, the side facing upwards is the upper side of the image forming apparatus, and the side facing downwards is the lower side of the image forming apparatus; when viewed from the front side to the rear side of the image forming apparatus, the side facing left is the left side of the image forming apparatus, and the side facing right is the right side of the image forming apparatus.

[0100] The direction in which the image forming apparatus extends in the front-back direction is the length direction of the image forming apparatus; the direction in which the image forming apparatus extends in the left-right direction is the width direction of the image forming apparatus; and the direction in which the image forming apparatus extends in the up-down direction is the height direction of the image forming apparatus.

[0101] The movable component 21 is used to accommodate the processing cartridge 1. The movable component 21 includes a plurality of receiving portions for accommodating the processing cartridge 1. In some examples, the movable component 21 includes four receiving portions for accommodating the processing cartridge 1, and four processing cartridges 1 can be placed in the movable component 21. The four processing cartridges 1 correspond to four different printing colors, and the four processing cartridges 1 are spaced apart along the length of the image forming apparatus. The movable component 21 can be a drawer.

[0102] Each processing box 1 corresponds to four conductive springs 22, which can be located on the right side of the main body 2. The four conductive springs 22 of each processing box 1 are spaced apart in the height direction of the image forming apparatus. The four electrical contacts 121 on the storage device 12 on the processing box 1 are only electrically connected to the four conductive springs 22 corresponding to that processing box 1. That is to say, the four electrical contacts 121 on the storage device 12 on the processing box 1 will not be electrically connected to the four conductive springs 22 corresponding to other processing boxes 1.

[0103] In one alternative implementation, such as Figure 3 , Figure 5 and Figure 6 As shown, two conductive springs 22 are spaced apart on the main body 2. The two conductive springs 22 can be electrically connected to the conductive component 10. The two conductive springs 22 are respectively the first conductive spring and the second conductive spring. It should be noted that the conductive component 10 on the processing box 1 will only be electrically connected to the conductive spring 22 corresponding to that processing box 1.

[0104] The image forming control unit 3 is in electrical contact with the first conductive spring, and is used to control the first conductive spring to be in a first-level state. Specifically, the image forming control unit 3 can control the first conductive spring to be in a first-level state, i.e., a low-level state, after it is connected to a zero-potential reference point. To further explain, "zero-potential reference point: In a circuit, selecting a point as the potential reference point means defining the potential of that point as zero. In a circuit, the potential reference point is usually marked with the symbol "⊥". Conventionally, the ground potential is often chosen as zero. In electronic circuits, a common point or the chassis is often chosen as the zero potential. It should be noted that although the potential of the potential reference point is defined as zero, the actual potential of this potential reference point is not necessarily zero."

[0105] The power supply unit 4 makes electrical contact with the second conductive spring through a pull-up resistor, providing a power supply voltage to the second conductive spring. This power supply voltage is greater than a preset value, meaning the image forming control unit controls the first conductive spring to be in a high-level state. Specifically, the preset value can be 3.3 volts. The power supply unit 4 provides 3.3 volts to the second conductive spring, causing the second conductive spring to be in a second-level state, i.e., a high-level state.

[0106] The image forming control unit 3 is also used to acquire the voltage signal of the first conductive spring and determine whether the voltage signal meets expectations. If the voltage signal meets expectations, it determines that the moving part 21 has been pushed forward and / or pulled out relative to the frame 20, and counts the number of times the moving part 21 has been pushed forward and / or pulled out relative to the frame 20. With this configuration, it is possible to determine whether color registration correction needs to be performed based on the number of times the moving part 21 has been pushed or pulled out, thereby enabling timely color registration correction and improving the printed image quality of the image forming apparatus.

[0107] Specifically, when the image forming control unit 3 acquires the voltage signal of the first conductive spring in the first level state, the voltage signal does not meet expectations; when the image forming control unit 3 acquires the voltage signal of the first conductive spring in the second level state, the voltage signal meets expectations.

[0108] Specifically, the image forming control unit 3 acquires the voltage signal of the first conductive spring and determines whether the voltage signal meets expectations. If the voltage signal includes a signal corresponding to the moving part 21 being pushed or pulled once, it is determined that the voltage signal meets expectations.

[0109] The signal corresponding to each push of the moving part 21 is described below, specifically including three stages. The signal in the first stage is a first-level state with a first duration; the signal in the second stage is a second-level state with a second duration, wherein the second duration is greater than or equal to a preset value; and the signal in the third stage is a first-level state with a third duration. Specifically, the first stage corresponds to the process of the moving part 21 being pushed, before the first and second conductive springs respectively contact the conductive component; the second stage corresponds to the time when both the first and second conductive springs are in contact with the conductive component; and the third stage corresponds to the time after the first and second conductive springs respectively contact the conductive component, wherein the first duration and the second duration are greater than 0. The signal corresponding to each pull of the moving part is similar to the signal corresponding to each push of the moving part 21, and will not be described in detail here.

[0110] Furthermore, if the voltage signal acquired by the image forming control unit 3 does not meet the above requirements, it is determined that the voltage signal does not meet expectations. For example, if the second duration is less than a preset value, the voltage signal is determined to be unexpected; or if the acquired signal only includes one or two of the signals corresponding to the three stages, the voltage signal is determined to be unexpected.

[0111] During the process of the moving part 21 being pushed forward and / or pulled out relative to the frame 20, the first conductive spring and the second conductive spring switch between a first connected state and a second disconnected state. Specifically, the first conductive spring and the second conductive spring can switch between a first connected state and a second disconnected state during the process of the moving part 21 being pushed forward relative to the frame 20; the first conductive spring and the second conductive spring can switch between a first connected state and a second disconnected state during the process of the moving part 21 being pulled out relative to the frame 20; and the first conductive spring and the second conductive spring can switch between a first connected state and a second disconnected state during the process of the moving part 21 being pushed forward and pulled out relative to the frame 20. Wherein, the first conductive spring and the second conductive spring being in the first connected state indicates that the first conductive spring is electrically connected to the second conductive spring through a conductor outside the image forming apparatus body; the first conductive spring and the second conductive spring being in the second disconnected state indicates that the first conductive spring is not connected to the second conductive spring through a conductor outside the image forming apparatus body. Additionally, within the image forming apparatus body, the first conductive spring is not electrically connected to the second conductive spring.

[0112] When the first conductive spring and the second conductive spring are connected, the image forming control unit 3 acquires the second level signal. Specifically, when the first conductive spring can be connected to a voltage of 0 volts and the second conductive spring can be connected to a voltage of 3.3 volts, the first conductive spring and the second conductive spring are connected, the voltage of the first conductive spring becomes 3.3 volts, the first conductive spring is in the second level state, and at this time, the image forming control unit 3 acquires the second level signal.

[0113] When the first conductive spring and the second conductive spring are not connected, the image forming control unit 3 acquires a first level signal. Specifically, when the first conductive spring can be connected to a voltage of 0 volts and the second conductive spring can be connected to a voltage of 3.3 volts, and when the first and second conductive springs are not connected, the voltage of the first conductive spring is still 0 volts, and the first conductive spring is in the first level state. At this time, the image forming control unit 3 acquires the first level signal. Based on the number of times the image forming control unit 3 acquires the signal corresponding to the moving part being pushed once or pulled once, the number of times the moving part 21 is pushed and / or pulled out relative to the frame 20 is counted. If the data acquired by the image forming control unit 3 is as follows... Figure 7 As shown, it can be determined that the moving part 21 has been pulled out twice and pushed in twice. The difference in the timing of the voltage signal generated during each push-in or pull-out process of the moving part 21 is due to the different speeds of the moving part 21 during the push or pull process, which results in different contact times between the conductive spring 22 and the conductive part 10.

[0114] Additionally, in other embodiments of this application, the image forming control unit 3 may also control the first conductive spring to be in a second level state and control the second conductive spring to be in a first level state, and determine whether the moving part 21 is pushed or pulled by detecting the voltage signal of the first conductive spring through the image forming control unit 3.

[0115] Optionally, such as Figure 1 As shown, the image forming control unit 3 is also used to determine when the number of times the moving part 21 is pushed forward and / or pulled out relative to the frame 20 exceeds a preset threshold, and to control the image forming apparatus to perform color registration correction processing.

[0116] The image forming control unit 3 stores a preset threshold for the moving part 21 to be pushed forward and / or pulled out relative to the frame 20.

[0117] The image forming apparatus may have an automatic color registration (ACR) function. ACR works to correct the relative positions of the four colors so that the four colors are precisely aligned, and when ACR is performed, the image quality is improved. In other implementations, the image forming apparatus may perform color registration correction in other ways.

[0118] Optionally, such as Figure 1 As shown, the image forming apparatus also includes a switching unit 5, which is electrically connected to the image forming control unit 3 and the first conductive spring, respectively.

[0119] Among them, such as Figure 2 As shown, the frame 20 includes a first side plate 201 and a second side plate 202 disposed opposite to each other, a first conductive spring and a second conductive spring are disposed on the first side plate 201, and the image forming control unit 3 is disposed on the second side plate 202.

[0120] The transfer unit 5 also includes a switching element. When the image forming control unit 3 determines that the moving part 21 is pushed forward or pulled out relative to the frame 20, the switching element is in a closed state; when the image forming control unit 3 controls the image forming apparatus to perform an image forming operation, the switching element is in an open state.

[0121] It should be noted that when the switching element is in the closed state, the image forming control unit 3 acquires the voltage signal of the first conductive spring; when the switching element is in the open state, the image forming control unit 3 does not acquire the voltage signal of the first conductive spring.

[0122] In one optional implementation, when the image forming control unit 3 detects that the front cover 23 is open, the control switch element is in a closed state, and the image forming control unit 3 acquires the voltage signal of the first conductive spring; when the image forming control unit 3 detects that the front cover 23 is closed, the control switch element is in a closed state, and the image forming control unit 3 does not acquire the voltage signal of the first conductive spring.

[0123] In one possible implementation, the switching element may be in an open state when the image forming control unit 3 determines that the moving part 21 is pushed forward or pulled out relative to the frame 20; and in a closed state when the image forming control unit 3 controls the image forming apparatus to perform an image forming operation.

[0124] Optionally, such as Figure 4 As shown, the main body 2 is equipped with a transfer belt 24, a secondary transfer roller 25, an inlet paper tray 26, a manual paper feed tray 27, a paper feed roller 28, a conveyor roller 29, a laser scanning unit 30, a heating roller 31, a pressure roller 32, an outlet roller 33, and an outlet paper tray 34. It should be noted that the processing box 1, transfer belt 24, secondary transfer roller 25, inlet paper tray 26, manual paper feed tray 27, paper feed roller 28, conveyor roller 29, laser scanning unit 30, heating roller 31, pressure roller 32, outlet roller 33, and outlet paper tray 34 are all located behind the front cover 23.

[0125] The processing box 1 also includes a photosensitive drum 14, a charging roller 13, and a developing roller 15.

[0126] The laser scanning unit 30 includes four optical paths. The charging rollers 13 of the four processing cartridges 1 are used to charge the surfaces of the four photosensitive drums 14 respectively, and the four optical paths of the laser scanning unit 30 emit laser beams to form electrostatic latent images on the surfaces of the photosensitive drums 14. The developing rollers 15 of the four processing cartridges 1 are used to develop toner images of their respective colors on the surfaces of the photosensitive drums 14 respectively.

[0127] The image forming apparatus employs a two-stage transfer method. The photosensitive drum in processing box 1 sequentially transfers the toner image onto transfer belt 24. The resulting color toner image on transfer belt 24 is then transferred a second time onto paper via secondary transfer roller 25. Paper is stored in paper tray 26, and feed roller 28 transports the stored paper to the transport path. Transport roller 29 transports the paper from the transport path to secondary transfer roller 25 for image transfer. Secondary transfer roller 25 transports the imaged paper to the clamping area of ​​heated roller 31 and pressure roller 32. Heated roller 31 and pressure roller 32 are used to fix the toner image on the paper. Heated roller 31 can be heated by ceramic heating. Heated roller 31 and pressure roller 32 transport the fixed paper to eject roller 33, which ejects the paper into ejection tray 34 and stacks it, thus completing the image printing.

[0128] This invention provides a detection device, including a detection signal generation unit.

[0129] The detection signal generation unit is used to generate detection signals indicating that the moving part 21 is pushed forward and / or pulled out relative to the frame 20 of the main body 2 of the image forming apparatus. Specifically, the detection signal generation unit can generate detection signals indicating that the moving part 21 is pushed forward relative to the frame 20 of the main body 2 of the image forming apparatus; the detection signal generation unit can also generate detection signals indicating that the moving part 21 is pulled out relative to the frame 20 of the main body 2 of the image forming apparatus; the detection signal generation unit can also generate detection signals indicating that the moving part 21 is pushed forward and pulled out relative to the frame 20 of the main body 2 of the image forming apparatus.

[0130] The detection signal is used to count the number of times the moving part 21 is pushed forward and / or pulled out relative to the frame 20. Specifically, when the detection signal generating unit generates a detection signal indicating that the moving part 21 is pushed forward relative to the frame 20 of the main body 2 of the image forming apparatus, the detection signal is used to count the number of times the moving part 21 is pushed forward relative to the frame 20; when the detection signal generating unit generates a detection signal indicating that the moving part 21 is pulled out relative to the frame 20 of the main body 2 of the image forming apparatus, the detection signal is used to count the number of times the moving part 21 is pushed forward and pulled out relative to the frame 20 of the main body 2 of the image forming apparatus; when the detection signal generating unit generates both push-forward and pull-out detection signals indicating that the moving part 21 is pushed forward and pulled out relative to the frame 20 of the main body 2 of the image forming apparatus, the detection signal is used to count the number of times the moving part 21 is pushed forward and pulled out. With this configuration, it is possible to determine whether color registration correction needs to be performed based on the number of times the moving part 21 is pushed forward or pulled out, thereby enabling timely color registration correction and improving the quality of the printed image from the image forming apparatus.

[0131] Figure 8 for Figure 5 A diagram showing the processing box placed in the moving part 21 in its working state. Figure 1 ; Figure 9 for Figure 5 A diagram showing the processing box placed in the moving part 21 in its working state. Figure 2 ; Figure 10 for Figure 5 A schematic diagram showing the contact between the conductive component 10 and the conductive spring when the processing box is placed in the moving component 21 and pushed or pulled. Figure 11 for Figure 10 A schematic diagram showing the contact between the conductive component 10 of the processing box and the conductive spring. Figure 8 and Figure 9 The storage device 12 of the processing box has four electrical contacts 121 that are in contact with four conductive springs 22. Figure 10 and Figure 11 Only two conductive springs 22 are shown, one of which is the first conductive spring and the other is the second conductive spring; Figure 10 and Figure 11 The conductive components are electrically connected to the first conductive spring and the second conductive spring, respectively.

[0132] Optionally, the detection signal includes a high-level signal and a low-level signal.

[0133] like Figure 5 and Figure 11 As shown, the detection signal generation unit includes a conductive component 10, which is disposed on the processing box 1 housed in the moving component 21. The detection signal generation unit also includes two conductive springs 22 spaced apart on the main body 2.

[0134] The conductive component 10 is used to switch between a first state connecting the two conductive springs 22 and a second state not connecting the two conductive springs 22 during the process of the moving component 21 being pushed forward and / or pulled out relative to the frame 20. Specifically, the conductive component 10 switches between the first state connecting the two conductive springs 22 and the second state not connecting the two conductive springs 22 during the process of the moving component 21 being pushed forward relative to the frame 20; the conductive component 10 can also switch between the first state connecting the two conductive springs 22 and the second state not connecting the two conductive springs 22 during the process of the moving component 21 being pulled out relative to the frame 20; and the conductive component 10 can also switch between the first state connecting the two conductive springs 22 and the second state not connecting the two conductive springs 22 during the process of the moving component 21 being pushed forward and pulled out relative to the frame 20.

[0135] When the conductive component 10 is in the first state, the detection signal generation unit generates a high-level signal; when the conductive component 10 is in the second state, the detection signal generation unit generates a low-level signal. In other embodiments, when the conductive component 10 is in the first state, the detection signal generation unit generates a low-level signal; when the conductive component 10 is in the second state, the detection signal generation unit generates a high-level signal.

[0136] like Figure 5 , Figure 10 and Figure 11 As shown, an embodiment of the present invention provides a conductive component 10, which is disposed on a processing box 1. The processing box 1 is detachably mounted on a moving component 21 of the main body 2 of the image forming apparatus, so that the moving component 21 is pushed forward or pulled out relative to the frame 20 of the main body 2 of the image forming apparatus.

[0137] The conductive component 10 is used to switch between a first state and a second state in which the two conductive springs 22 spaced apart on the communicating body 2 are not connected during the process of the moving component 21 being pushed forward and / or pulled out relative to the frame 20, so that the detection device including the conductive component 10 generates a detection signal indicating that the moving component 21 is pushed forward and / or pulled out relative to the frame 20.

[0138] Specifically, during the process of the moving part 21 being pushed forward relative to the frame 20, the conductive part 10 can switch between a first state and a second state where the two conductive springs 22 spaced apart on the connecting body 2 are not connected, so that the detection device containing the conductive part 10 generates a detection signal indicating that the moving part 21 is being pushed forward relative to the frame 20; or during the process of the moving part 21 being pulled out relative to the frame 20, the conductive part 10 can switch between a first state and a second state where the two conductive springs 22 spaced apart on the connecting body 2 are not connected, so that the detection device containing the conductive part 10 generates a detection signal indicating that the moving part 21 is being pulled out relative to the frame 20; or during the process of the moving part 21 being pushed forward and pulled out relative to the frame 20, the conductive part 10 can switch between a first state and a second state where the two conductive springs 22 spaced apart on the connecting body 2 are not connected, so that the detection device containing the conductive part 10 generates a detection signal indicating that the moving part 21 is being pushed forward and pulled out relative to the frame 20.

[0139] The detection signal is used to count the number of times the moving part 21 is pushed forward and / or pulled out relative to the frame 20. Specifically, when the detection device including the conductive part 10 generates a detection signal indicating that the moving part 21 is pushed forward relative to the frame 20, the detection signal is used to count the number of times the moving part 21 is pushed forward relative to the frame 20; when the detection device including the conductive part 10 generates a detection signal indicating that the moving part 21 is pulled out relative to the frame 20, the detection signal is used to count the number of times the moving part 21 is pulled out relative to the frame 20; when the detection device including the conductive part 10 generates both push-forward and pull-out detection signals indicating that the moving part 21 is pushed forward and pulled out relative to the frame 20, the detection signal is used to count the number of times the moving part 21 is pushed forward and pulled out relative to the frame 20. With this configuration, it is possible to determine whether color registration correction needs to be performed based on the number of times the moving part 21 is pushed or pulled out, thereby enabling timely color registration correction and improving the quality of the printed image from the image forming apparatus.

[0140] Optionally, the detection signal includes a high-level signal and a low-level signal.

[0141] When the conductive component 10 is in the first state, the detection signal generation unit generates a high-level signal; when the conductive component 10 is in the second state, the detection signal generation unit generates a low-level signal. In other embodiments, when the conductive component 10 is in the first state, the detection signal generation unit generates a low-level signal; when the conductive component 10 is in the second state, the detection signal generation unit generates a high-level signal.

[0142] In one optional embodiment, the conductive component 10 can connect to one of two spaced-apart conductive springs 22 on the main body 2, where one conductive spring 22 can be connected to a 3.3-volt voltage and the other conductive spring 22 can be connected to a 0-volt voltage. The typical high-level range is 2V-3.3V; in this embodiment, a 3.3-volt high-level signal is selected. The typical low-level range is 0V-0.6V; in this embodiment, a 0-volt low-level signal is selected. When the conductive component 10 is in the first state, it connects the conductive spring 22 connected to the 3.3-volt voltage and the conductive spring 22 connected to the 0-volt voltage, and the detection signal generation unit generates a 3.3-volt voltage signal. When the conductive component 10 is in the second state, it disconnects the conductive spring 22 connected to the 3.3-volt voltage and the conductive spring 22 connected to the 0-volt voltage, and the detection signal generation unit generates a 0-volt voltage signal.

[0143] Optionally, the conductive component 10 includes a first connection end and a second connection end. When the conductive component 10 is in the first state, the first connection end is electrically connected to one of the two conductive springs 22, and the second connection end is electrically connected to the other of the two conductive springs 22.

[0144] The end of the conductive component 10 that is in electrical contact with one of the two conductive springs 22 is the first connection end, and the end of the conductive component 10 that is in electrical contact with the other of the two conductive springs 22 is the second connection end.

[0145] In one optional embodiment, the conductive spring 22 electrically connected to the first connection terminal is connected to a voltage of 3.3 volts, and the conductive spring 22 electrically connected to the second connection terminal is connected to a voltage of 0 volts. When the conductive component 10 is in the first state, the first connection terminal is electrically connected to the conductive spring 22 connected to the 3.3 volt voltage, and the second connection terminal is electrically connected to the conductive spring 22 connected to the 0 volt voltage. At this time, the conductive spring 22 connected to the 3.3 volt voltage and the conductive spring 22 connected to the 0 volt voltage are connected through the first connection terminal and the second connection terminal, and the voltage of both conductive springs 22 is 3.3 volts. The detection signal generation unit generates a 3.3 volt voltage signal. When the conductive component 10 is in the second state, the first connection terminal is not electrically connected to the conductive spring 22 connected to 3.3 volts, and the second connection terminal is not electrically connected to the conductive spring 22 connected to 0 volts. At this time, the conductive spring 22 connected to 3.3 volts and the conductive spring 22 connected to 0 volts are not conducting, the voltage on the two conductive springs 22 remains unchanged, and the detection signal generation unit generates a 0 volt voltage signal.

[0146] Figure 12 for Figure 11 A schematic diagram showing the contact between the conductive component and the conductive spring. Figure 12 The direction indicated by the middle arrow X is the direction in which the moving part 21 is pushed relative to the frame 20; Figure 12The direction indicated by the middle arrow X is the first direction; Figure 12 The dashed box in the figure represents the area on the conductive component 10 that can be contacted by the conductive spring 22.

[0147] Specifically, such as Figure 12 As shown, along the direction in which the moving part 21 is pushed relative to the frame 20, the projected length of the area on the conductive part 10 that can be contacted by the conductive spring 22 in the X direction exceeds a preset value. This is configured to prevent the contact time between the moving part 21 and the conductive spring 22 from being too short when the conductive part 10 is in the first state, which would cause the detection device containing the conductive part 10 to generate an instantaneous detection signal.

[0148] It can be further explained that the two conductive springs 22 are the first conductive spring and the second conductive spring, respectively. Along the direction in which the moving part 21 is pushed relative to the frame by the frame 20, the projected length of the area on the conductive part 10 that can be contacted by the first conductive spring in the pushing direction and the projected length of the area on the conductive part 10 that can be contacted by the second conductive spring in the pushing direction both exceed the preset value.

[0149] The preset value is a preset width value that ensures the detection device containing the conductive component 10 generates a detection signal for a certain period of time when the conductive component 10 is in the first state. It should be noted that the time required to ensure the detection device containing the conductive component 10 generates a detection signal can be set as needed. In some examples, the preset width value is 5mm.

[0150] The conductive component 10 can be square. In other cases, the conductive component 10 can also be other irregular shapes, which are not limited here.

[0151] like Figure 12 As shown, along the direction in which the moving part 21 is pushed relative to the frame 20, the projected length of the area on the conductive part 10 that can be contacted by the conductive spring 22 in the X direction is a.

[0152] Specifically, such as Figure 12 As shown, along the first direction, the maximum length of the line connecting any two points in the area on the conductive component 10 that can be contacted by the two conductive springs 22 is greater than or equal to the minimum length of the line connecting any two points in the projection area of ​​the two conductive springs 22 on the plane where the conductive component 10 is located.

[0153] The first direction is perpendicular to the direction in which the moving part 21 is pushed and / or pulled out relative to the frame 20. In some examples, the direction in which the moving part 21 is pushed and / or pulled out relative to the frame 20 is horizontal, and the first direction is vertical.

[0154] Specifically, the two conductive springs are the first conductive spring and the second conductive spring, respectively. The area on the conductive component 10 that can be contacted by the first conductive spring is the first contact area, and the area on the conductive component 10 that can be contacted by the second conductive spring is the second contact area. The projection area of ​​the first conductive spring on the plane where the conductive component 10 is located is the first projection area, and the projection area of ​​the second conductive spring on the plane where the conductive component 10 is located is the second projection area. Along the first direction, the maximum length of the line connecting any point in the first contact area and any point in the second contact area is the first maximum value. Along the first direction, the minimum length of the line connecting any point in the first projection area and any point in the second projection area is the second minimum value. The first maximum value is greater than or equal to the second minimum value. The first direction is perpendicular to the direction in which the moving component 21 is pushed and / or pulled out relative to the frame 20.

[0155] Further explanation is possible, such as... Figure 12 As shown, along the first direction, the maximum length of the line connecting any two points in the area where the two conductive springs 22 can contact each other on the conductive component 10 is b, and the minimum length of the line connecting any two points in the projection area of ​​the two conductive springs 22 on the plane where the conductive component 10 is located is c. Therefore, b ≥ c. This setting is to ensure that the conductive component 10 and the conductive springs 22 can be electrically connected.

[0156] The first direction is perpendicular to the direction in which the moving part 21 is pushed and / or pulled out relative to the frame 20. In some examples, the direction in which the moving part 21 is pushed and / or pulled out relative to the frame 20 is horizontal, and the first direction is vertical.

[0157] Furthermore, such as Figure 12 As shown, along the first direction, the minimum length of the line connecting any two points in the area on the conductive component 10 that can be contacted by the two conductive springs 22 is less than or equal to the maximum length of the line connecting any two points in the projection area of ​​the two conductive springs 22 on the plane where the conductive component 10 is located.

[0158] Specifically, the two conductive springs are designated as a first conductive spring and a second conductive spring. The area on the conductive component 10 that can be contacted by the first conductive spring is the first contact area, and the area on the conductive component 10 that can be contacted by the second conductive spring is the second contact area. The projection area of ​​the first conductive spring on the plane of the conductive component is the first projection area, and the projection area of ​​the second conductive spring on the plane of the conductive component is the second projection area. Along the first direction, the minimum length of the line connecting any point in the first contact area and any point in the second contact area is the first minimum value. Along the first direction, the maximum length of the line connecting any point in the first projection area and any point in the second projection area is the second maximum value. The first minimum value is less than or equal to the second maximum value. The first direction is perpendicular to the direction in which the moving component 21 is pushed and / or pulled out relative to the frame 20.

[0159] Further explanation is possible, such as... Figure 12 As shown, along the first direction, the minimum length of the line connecting any two points in the area where the two conductive springs 22 can contact each other on the conductive component 10 is d, and the maximum length of the line connecting any two points in the projection area of ​​the two conductive springs 22 on the plane where the conductive component 10 is located is e, then d≤e. This setting is to ensure that the conductive component 10 and the conductive springs 22 can be electrically connected.

[0160] Optionally, the conductive component 10 includes one or more metal conductive sheets that are electrically connected to each other.

[0161] In one alternative implementation, such as Figure 6 and 11 As shown, the conductive component 10 includes a metal conductive sheet that can electrically connect a 3.3-volt conductive spring 22 and a 0-volt conductive spring 22.

[0162] Figure 13 A schematic diagram of a second type of processing box provided in an embodiment of the present invention; Figure 14 for Figure 13 A schematic diagram of the storage device and conductive components in the diagram; Figure 15 for Figure 13 A schematic diagram showing the contact between the conductive components of the processing box and the conductive spring.

[0163] In another alternative implementation, such as Figures 13 to 15 As shown, the conductive component 10 includes two electrically connected metal conductive sheets. One metal conductive sheet can be electrically connected to a conductive spring 22 with a voltage of 3.3 volts, and the other can be electrically connected to a conductive spring 22 with a voltage of 0 volts.

[0164] like Figure 2 and Figure 5 As shown, an embodiment of the present invention provides a processing box 1, including a conductive component 10.

[0165] The conductive component 10 of the processing box 1 provided in this embodiment of the invention is the same as the conductive component 10 described above, and can bring the same or similar technical effects, which will not be described in detail here.

[0166] like Figure 2 and Figure 5 As shown, an embodiment of the present invention provides another processing box 1, which is detachably mounted on the moving part 21 of the main body 2 of the image forming apparatus, so that as the moving part 21 is pushed forward or pulled out relative to the frame 20 of the main body 2 of the image forming apparatus, the processing box 1 includes: a housing 11, an imaging member and a conductive part 10.

[0167] The housing 11 has a cavity for accommodating the imaging component, which is mounted on the housing 11. For example... Figure 2 As shown, the imaging components include a charging roller 13, a photosensitive drum 14, a developing roller 15, and a powder feeding roller 16.

[0168] The charging roller 13 is used to charge the photosensitive drum 14. After the photosensitive drum 14 is charged, its surface becomes charged. Then, the laser scanning unit 30 in the image forming apparatus emits a laser to the photosensitive drum 14, forming an electrostatic latent image corresponding to the desired image on the surface of the photosensitive drum 14. The toner feeding roller 16 conveys toner to the developing roller 15, and the developing roller 15 transfers the toner onto the photosensitive drum 14, so that the electrostatic latent image on the surface of the photosensitive drum 14 becomes a visible toner image.

[0169] The conductive component 10 is used to switch between a first state and a second state where the two conductive springs 22 spaced apart on the connecting body 2 are not connected during the process of the moving component 21 being pushed and / or pulled out relative to the frame 20. This allows the detection device including the conductive component 10 to generate a detection signal indicating that the moving component 21 is pushed and / or pulled out relative to the frame 20. The detection signal is used to count the number of times the moving component 21 is pushed and / or pulled out relative to the frame 20. With this configuration, it is possible to determine whether color registration correction needs to be performed based on the number of times the moving component 21 is pushed or pulled out, thereby enabling timely color registration correction and improving the quality of the printed image from the image forming apparatus.

[0170] Figure 11 The direction indicated by the middle arrow X is the direction in which the moving part 21 is pushed relative to the frame 20.

[0171] Optionally, such as Figure 5 , Figure 6 and Figure 11As shown, the processing box 1 also includes a storage device 12, which is disposed in the housing 11. The storage device 12 includes a substrate and an electrical contact 121 electrically connected to the substrate. The electrical contact 121 is used to electrically connect to the conductive spring 22 disposed on the main body 2.

[0172] The conductive component 10 can be disposed on the storage device 12. Both the conductive component 10 and the electrical contact 121 are disposed on the storage device 12, which can save design costs.

[0173] In one alternative embodiment, the conductive member 10 is disposed on the substrate. Both electrical contacts 121 are closer to the rear side of the housing 11 than to the front side of the housing 11, and the conductive member 10 is closer to the front side of the housing 11 than to the rear side of the housing 11 where the two electrical contacts 121 are closer. Further, in the direction in which the moving member 21 is pushed relative to the frame 20, the conductive member 10 is located in front of the electrical contacts 121, and is closer to the front side of the housing 11 than to the rear side of the housing 11. The direction from the rear side to the front side of the housing 11 is the same as the direction in which the moving member 21 is pushed relative to the frame 20.

[0174] In this embodiment, by placing the conductive component 10 on the substrate of the storage device 12, the two electrical contacts 121 are closer to the rear side of the housing 11 than the front side of the housing 11. Compared to the rear side of the housing 11 where the two electrical contacts 121 are closer, the conductive component 10 is closer to the front side of the housing 11. Furthermore, in the direction in which the moving component 21 is pushed relative to the frame 20, the conductive component is closer to the position of the front side corresponding to the rear side than the rear side where the electrical contacts are located. As a result, the image forming apparatus body does not need to be separately provided with other conductive springs different from the conductive springs 22 for contacting the conductive component 10, thus saving costs.

[0175] Figure 16 This is a schematic diagram of a third type of processing box provided in an embodiment of the present invention. Figure 16 The direction indicated by the middle arrow X is the direction in which the moving part 21 is pushed relative to the frame 20. The X direction is the direction from the rear side to the front side of the housing.

[0176] Optionally, such as Figure 16As shown, the processing box 1 also includes a storage device 12, which is disposed on the housing 11. The storage device 12 includes a substrate and electrical contacts 121 electrically connected to the substrate. The electrical contacts 121 are used to electrically connect to conductive springs 22 disposed on the main body 2. In the direction in which the moving member 21 is pushed relative to the frame 20, the conductive member 10 is located in front of the electrical contacts 121. Compared to the front side of the housing 11, the conductive member is closer to the rear side of the housing 11. It should be noted that in the direction in which the moving member 21 is pushed relative to the frame 20, the side in front of the housing 11 is the front side of the housing 11, and the side opposite to the front side of the housing 11 is the rear side of the housing 11. That is, the direction from the rear side of the housing 11 to the front side of the housing 11 is the direction in which the moving member 21 is pushed relative to the frame 20. The conductive component 10 may not be disposed on the storage device 12, but is disposed on the housing 11. The two electrical contacts 121 are closer to the rear side of the housing 11. Compared with the electrical contacts 121 being closer to the rear side of the housing 11, the conductive component 10 is closer to the front side of the housing 11. The direction from the rear side to the front side of the housing 11 is the same as the direction in which the moving component 21 is pushed relative to the frame 20.

[0177] In one alternative implementation, such as Figure 15 As shown, the housing 11 includes a powder hopper housing 111 and a waste powder hopper housing 112, which are detachably connected. The storage device 12 and the conductive component 10 are disposed at one end of the waste powder hopper housing 112. Compared to the rear side of the housing 11 where the waste powder hopper housing 112 is located, the conductive component 10 is located closer to the front side of the housing 11 where the powder hopper housing 111 is located, which corresponds to the rear side of the housing 11.

[0178] To further explain, the housing 11 includes a powder hopper housing 111 and a waste powder hopper housing 112, which are detachably connected. The storage device 12 and the conductive component 10 are disposed on the waste powder hopper housing 112. Compared to the front side where the waste powder hopper housing 112 is located, the conductive component 10 is located closer to the rear side where the powder hopper housing 111 is located, which is the same as the front side. The direction from the rear side to the front side of the housing 11 is the direction in which the moving component 21 is pushed relative to the frame 20.

[0179] Figure 16 The dashed box in the image represents the fixed area for the conductive component. For example... Figure 2 and Figure 16 As shown, this embodiment of the invention provides another processing box 1, which is detachably mounted on the moving part 21 of the main body 2 of the image forming apparatus, so that as the moving part 21 is pushed forward or pulled out relative to the frame 20 of the main body 2 of the image forming apparatus, the processing box 1 includes: a housing 11, an imaging member, and a fixed area.

[0180] The housing 11 has a cavity for accommodating the imaging component, which is mounted on the housing 11. For example... Figure 4 As shown, the imaging components include a charging roller 13, a photosensitive drum 14, a developing roller 15, and a powder feeding roller 16.

[0181] The charging roller 13 is used to charge the photosensitive drum 14. After the photosensitive drum 14 is charged, its surface becomes charged. Then, the image forming apparatus emits a laser to the photosensitive drum 14, forming an electrostatic latent image corresponding to the desired image on the surface of the photosensitive drum 14. The toner feeding roller 16 conveys toner to the developing roller 15, and the developing roller 15 transfers the toner onto the photosensitive drum 14, so that the electrostatic latent image on the surface of the photosensitive drum 14 becomes a visible toner image.

[0182] A fixed area is used to fix the conductive component 10. The conductive component 10 is used to switch between a first state and a second state where the two conductive springs 22 spaced apart on the connecting body 2 are not connected during the process of the moving component 21 being pushed and / or pulled out relative to the frame 20. This allows the detection device containing the conductive component 10 to generate a detection signal indicating that the moving component 21 is pushed and / or pulled out relative to the frame 20. The detection signal is used to count the number of times the moving component 21 is pushed and / or pulled out relative to the frame 20. This configuration allows for determining whether color registration correction needs to be performed based on the number of times the moving component 21 is pushed or pulled out, thus enabling timely color registration correction and improving the quality of the printed image from the image forming apparatus.

[0183] Optionally, such as Figure 16 As shown, a storage device 12 is provided on the processing box 1, and the fixed area can be provided on the storage device 12. In other cases, the fixed area can also be provided on the housing 11.

[0184] The storage device 12 can store information such as the batch number, manufacturing date, and color of the processing box 1.

[0185] Figure 17 This is a partial schematic diagram of the fourth type of processing box provided in an embodiment of the present invention; Figure 17 The dashed box in the image represents the fixed area for the conductive component. For example... Figure 17 As shown, a positioning mark 122 for positioning the conductive component 10 is provided in the fixed area.

[0186] The positioning mark 122 can be L-shaped. In other implementations, the positioning mark 122 can also be other shapes.

[0187] In one optional embodiment, the storage device 12 is provided with a positioning mark 122, which is located within a fixed area and is used to position the conductive component 10. Positioning the conductive component 10 using the positioning mark 122 improves the fixing accuracy of the conductive component 10.

[0188] Optionally, the processing box 1 further includes a storage device 12 disposed in the housing 11. The storage device 12 includes a substrate and an electrical contact 121 electrically connected to the substrate. The electrical contact 121 is used to electrically connect to the conductive spring 22 disposed on the main body 2.

[0189] The conductive component 10 may be disposed on the storage device 12. In other embodiments, the conductive component 10 may not be disposed on the storage device 12, but may be disposed on the housing 11.

[0190] In this embodiment, the position of the conductive component 10 can be referenced to the position of the conductive component 10 of the processing box in the above embodiment.

[0191] like Figure 18 As shown, an embodiment of the present invention provides a detection method applied to an image forming apparatus, comprising:

[0192] S100: The first conductive spring provided on the main body 2 of the image forming apparatus is in a first level state.

[0193] S200: The second conductive spring on the control body 2 is in the second level state.

[0194] S300: During the process of the moving part 21 of the main body 2 being pushed forward and / or pulled out relative to the frame 20 of the main body 2, the voltage signal of the first conductive spring is acquired;

[0195] S400: Determine whether the voltage signal of the first conductive spring meets expectations. When the voltage signal of the first conductive spring meets expectations, determine that the moving part 21 is pushed forward and / or pulled out relative to the frame 20, and count the number of times the moving part 21 is pushed forward and / or pulled out relative to the frame 20.

[0196] The specific process of the detection method can be referred to the description in the image forming apparatus, and will not be elaborated here.

[0197] It should be noted that the image forming control unit 3 of the image forming apparatus executes the detection method.

[0198] Before S100: the first conductive spring provided on the main body 2 of the image forming apparatus is in a first level state, the method further includes:

[0199] The front cover of the image forming apparatus was found to have been opened.

[0200] Optionally, after counting the number of times the moving part 21 is pushed forward and / or pulled out relative to the frame 20, the method further includes:

[0201] S500; Determine whether the number of times the moving part 21 is pushed and / or pulled out relative to the frame 20 exceeds a preset threshold. If the number exceeds the preset threshold, determine that color registration correction processing needs to be performed.

[0202] If the number of times the moving part 21 is pushed and / or pulled out relative to the frame 20 exceeds a preset threshold, then color registration correction is performed, i.e., S610 is executed; if the number of times the moving part 21 is pushed and / or pulled out relative to the frame 20 does not exceed the preset threshold, then color registration correction is not required, i.e., S620 is executed.

[0203] The image forming apparatus may have an automatic color registration (ACR) function. ACR works to correct the relative positions of the four colors so that the four colors are precisely aligned, and when ACR is performed, image quality is improved. In other implementations, the image forming apparatus may perform color registration in other ways.

[0204] S620: The image forming apparatus enters the ready mode, that is, the image forming apparatus can work normally.

[0205] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
