Description

Technical Field

[0001] This application relates to the field of electronic imaging technology, specifically to a consumable chip, consumable, image forming apparatus, detection method, and storage medium. Background Technology

[0002] Currently, image forming apparatuses such as printers often have detachably mounted processing cartridges for imaging. Since the removal or movement of the processing cartridge affects the image forming performance of the apparatus, it is necessary to detect whether the processing cartridge has been removed or moved in order to promptly correct and adjust relevant parameters and ensure the image forming performance of the apparatus. For example, replacing or removing and reinstalling the processing cartridge usually alters its state within the image forming apparatus, causing the original imaging system control parameters, such as laser exposure power and high voltage parameters, to no longer be optimal, thus affecting the imaging effect. Currently, the common detection method uses limit switches and photoelectric switches to determine whether the processing cartridge has been removed or moved; however, this approach increases costs due to additional structural design and electrical wiring. Summary of the Invention

[0003] In view of this, this application provides a consumable chip, consumable, image forming apparatus, detection method, electronic device, and storage medium to solve the problem that the use of limit switches and photoelectric switches in the prior art to determine whether the processing box has been disassembled or moved increases the cost due to additional structural design and electrical connection wiring.

[0004] In a first aspect, embodiments of this application provide a consumable chip, which is used to be mounted on a consumable, the consumable being used to be mounted at a designated location in an image forming apparatus, the consumable chip comprising:

[0005] Consumable chip body;

[0006] The first contact is disposed on the consumable chip body and is used to electrically connect with the contact of the image forming apparatus when the consumable is installed at the designated position, so as to interact with the image forming apparatus.

[0007] The second contact is disposed on the consumable chip body and is used to send a specific detection signal to the image forming apparatus when it is electrically connected to the contact of the image forming apparatus. The specific detection signal is used to characterize the displacement of the consumable.

[0008] When the consumable material leaves the designated position of the image forming apparatus, the contacts of the image forming apparatus move along a preset displacement trajectory on the consumable chip body, and the second contacts are distributed on the preset displacement trajectory.

[0009] In this embodiment, the second contact is set on a preset displacement trajectory, so that when the consumable leaves the designated position of the image forming apparatus, the contact of the image forming apparatus can move along the preset displacement trajectory to electrically connect with the second contact, so as to receive the specific detection signal output by the second contact. No additional structural design and electrical connection lines are required, which reduces the chip cost.

[0010] Furthermore, the embodiments of this application detect whether the consumable has shifted by using a specific detection signal, which is more identifiable than a simple high-level or low-level signal, avoids detection errors, and enhances the reliability of the detection results.

[0011] In one possible implementation, when the consumable leaves the designated position of the image forming apparatus, the contact of the image forming apparatus leaves the contact area of ​​the first contact and moves along the preset displacement trajectory to the contact area of ​​the second contact, wherein the first contact and the second contact are distributed at both ends of the preset displacement trajectory.

[0012] The preset displacement trajectory of this application embodiment can cover a relatively large range. Setting the first contact point and the second contact point at both ends of the displacement trajectory can ensure the accuracy of the contact connection with the image forming device.

[0013] In one possible implementation, the image forming apparatus includes a plurality of contacts, each of which moves along a different preset displacement trajectory on the consumable chip body.

[0014] In this embodiment of the application, the contacts of the image forming apparatus can be realized by contact springs, that is, the image forming apparatus includes multiple contact springs, and each contact spring moves along a different preset displacement trajectory on the consumable chip body.

[0015] In one possible implementation, the first contact includes a first power contact, a data signal contact, a first ground contact, and a clock signal contact, wherein the first power contact, the data signal contact, the first ground contact, and the clock signal contact are respectively distributed on different preset displacement trajectories.

[0016] In this embodiment, the first power contact, data signal contact, first ground contact, and clock signal contact are distributed on different preset displacement trajectories, and can be electrically connected to the contacts of the corresponding image forming apparatus to form corresponding information transmission channels.

[0017] In one possible implementation, the second contact includes a second power contact, a second ground contact, and a signal output contact, wherein the second power contact, the second ground contact, and the signal output contact are respectively distributed on different preset displacement trajectories.

[0018] In this embodiment, the second power contact, the second ground contact, and the signal output contact are distributed on different preset displacement trajectories, and can be electrically connected to the contacts of the corresponding image forming apparatus to form corresponding information transmission channels.

[0019] In one possible implementation, the second grounding contact and the first grounding contact are distributed on the same preset displacement trajectory.

[0020] In this embodiment of the application, the second grounding contact and the first grounding contact are set on the same preset displacement trajectory, so that when the grounding contact of the image forming apparatus moves along the preset displacement trajectory, it can be electrically connected to the second grounding contact and the first grounding contact respectively, without having to set an additional grounding contact on the image forming apparatus, thus reducing the complexity of the circuit structure design.

[0021] In one possible implementation, the contacts of the image forming apparatus move along a preset displacement trajectory on the consumable chip body, including:

[0022] When the contacts of the image forming apparatus move along a preset displacement trajectory on the consumable chip body, they first complete the electrical connection with the second grounding contact, then complete the electrical connection with the second power supply contact, and finally complete the electrical connection with the signal output contact.

[0023] The embodiments of this application can reduce the impact caused by unstable power supply and ground wire when the second contact is electrically connected to the contact of the image forming apparatus, thereby ensuring the stability of the detection signal.

[0024] In one possible implementation, the contacts of the image forming apparatus move along a preset displacement trajectory on the consumable chip body, including:

[0025] When the contacts of the image forming apparatus move along a preset displacement trajectory on the consumable chip body, they first complete the electrical connection with the second grounding contact and the second power contact, and then complete the electrical connection with the signal output contact.

[0026] The embodiments of this application can reduce the impact caused by unstable power supply and ground wire when the second contact is electrically connected to the contact of the image forming apparatus, thereby ensuring the stability of the detection signal.

[0027] In one possible implementation, when the contacts of the image forming apparatus are electrically connected to the signal output contacts, both the second ground contact and the second power contact are electrically connected to the contacts of the image forming apparatus.

[0028] In one possible implementation, the area of ​​the signal output contact on the preset displacement trajectory is greater than a set area threshold, so that during the process of the consumable leaving the designated position of the image forming apparatus, the electrical connection time between the contact of the image forming apparatus and the signal output contact is greater than a preset time threshold.

[0029] The embodiments of this application can avoid the situation where the output time of a specific detection signal is too short and the signal cannot be detected due to the user moving the consumable chip too fast.

[0030] In one possible implementation, the consumable chip is provided with a detection circuit, which is electrically connected to the second contact and is used to output a specific detection signal when the second contact is electrically connected to the contact of the image forming apparatus.

[0031] In this embodiment, the detection circuit is placed on the consumable chip, which reduces the need for additional structural design. Furthermore, the detection circuit can share electrical connection lines with the consumable chip, thus saving on electrical connection lines as well.

[0032] In one possible implementation, the detection circuit includes a Pierce oscillator.

[0037] Determine whether the specific detection signal is consistent with the preset detection signal;

[0038] If the specific detection signal is consistent with the preset detection signal, it is determined that the consumable has been displaced.

[0039] Fifthly, embodiments of this application provide a displacement detection device for consumables, including consumables as described in any of the second aspects, wherein when the consumables leave a designated position of the image forming apparatus, the image forming apparatus is electrically connected to the second contact; the displacement detection device further includes:

[0040] A receiving unit is configured to receive a specific detection signal from the second contact point;

[0041] A judgment unit is used to determine whether the specific detection signal is consistent with a preset detection signal;

[0042] The determining unit is used to determine that the consumable has been displaced if the specific detection signal is consistent with the preset detection signal.

[0044] processor;

[0045] Memory;

[0046] The memory stores a computer program that, when executed, causes the electronic device to perform any of the methods described in the fourth aspect.

[0067] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0068] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0069] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0070] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0071] It should be understood that, in the following description, "circuit" refers to a conductive loop consisting of at least one element or sub-circuit connected by an electrical or electromagnetic link. When an element or circuit is said to be "connected" to another element or "connected" between two nodes, it can be directly coupled or connected to the other element, or there may be intermediate elements. The connection between elements can be physical, logical, or a combination thereof. Conversely, when an element is said to be "directly coupled to" or "directly connected" to another element, it means that there are no intermediate elements between them.

[0072] Currently, image forming apparatuses such as printers often have detachably installed processing cartridges for imaging. Since the removal or movement of the processing cartridge affects the image forming performance of the apparatus, it is necessary to detect whether the processing cartridge has been removed or moved to allow for timely adjustment of relevant parameters and ensure optimal image forming performance. For example, replacing or reinstalling the processing cartridge usually alters its state within the image forming apparatus, causing the original imaging system control parameters, such as laser exposure power and high-voltage parameters, to no longer be optimal, thus affecting image quality. In such cases, color calibration is required to optimize the imaging system control parameters and ensure printer image quality. Currently, the common detection method uses limit switches and photoelectric switches to determine whether the processing cartridge has been removed or moved. However, this method increases costs due to additional structural design and electrical wiring.

[0073] To address the aforementioned issues, embodiments of this application provide a consumable chip, a consumable, an image forming apparatus, a detection method, an electronic device, and a storage medium. In this embodiment, a second contact is positioned on a preset displacement trajectory. When the consumable leaves a designated position on the image forming apparatus, the contact of the image forming apparatus moves along the preset displacement trajectory to electrically connect with the second contact, thereby receiving a specific detection signal output by the second contact. This eliminates the need for additional structural design and electrical wiring, reducing chip costs.

[0074] The following explanation is based on the accompanying drawings.

[0075] See Figure 1 This is a schematic diagram of the structure of a consumable chip provided in an embodiment of this application. Figure 1 As shown, the consumable chip 100 includes a consumable chip body 110, a first contact 120 disposed at one end of the consumable chip body, and a second contact 130 disposed at the other end of the consumable chip body. The consumable chip 100 is used to mount on a consumable, which is then detachably mounted at a designated location on the image forming apparatus. Exemplarily, the consumable can be an ink cartridge or a toner cartridge, etc. Image forming apparatuses include, but are not limited to, printers, copiers, fax machines, multi-function image processing and copying apparatuses, electrostatic printing apparatuses, and any other similar apparatuses.

[0076] In specific implementation, the consumable can be installed to a designated position of the image forming apparatus along a preset displacement trajectory. When the consumable is installed to the designated position of the image forming apparatus, the first contact 120 is electrically connected to the contact of the image forming apparatus, thereby forming a first information transmission channel between the consumable chip 100 and the image forming apparatus. The consumable chip 100 interacts with the image forming apparatus through the first information transmission channel. When the consumable is not installed at the designated position of the image forming apparatus, such as when the consumable leaves the designated position of the image forming apparatus along the preset displacement trajectory, the second contact 130 is electrically connected to the contact of the image forming apparatus, thereby forming a second information transmission channel between the consumable chip 100 and the image forming apparatus. The consumable chip 100 sends a specific detection signal to the image forming apparatus through the second information transmission channel. This specific detection signal is used to characterize the displacement of the consumable, thereby determining whether the consumable has been disassembled or moved. It is understood that this specific detection signal can reflect that the consumable has left the designated position of the image forming apparatus, or that the consumable is not installed at the designated position of the image forming apparatus. For example, this may be due to a change in the installation state of the consumable after replacement or disassembly and reinstallation.

[0077] In practice, when the consumable material leaves the designated position of the image forming apparatus, the contacts of the image forming apparatus move away from the first contact 120 on the consumable chip body 110 and move along a preset displacement trajectory, while the second contact 130 is distributed on the preset displacement trajectory. By placing the second contact 130 on the preset displacement trajectory, the contacts of the image forming apparatus can be electrically connected to the second contact 130 during the movement along the preset displacement trajectory, thereby establishing a second information transmission channel. The image forming apparatus receives the specific detection signal output by the second contact 130 through the second information transmission channel. This arrangement eliminates the need for additional structural design on the consumable chip 100, reducing chip costs.

[0078] It is understood that the preset displacement trajectory of the contacts of the image forming apparatus on the consumable chip body can be the same as the preset displacement trajectory of the consumable when it is installed or removed from the designated position of the image forming apparatus. In some embodiments, when the consumable leaves the designated position of the image forming apparatus, the contacts of the image forming apparatus leave the contact area of ​​the first contact and move along the preset displacement trajectory to the contact area of ​​the second contact, with the first and second contacts distributed at both ends of the preset displacement trajectory. The preset displacement trajectory of this application embodiment has a relatively large coverage area. Setting the first and second contacts at both ends of the chip body, that is, setting the first and second contacts at both ends of the preset displacement trajectory, can ensure that the first and second contacts have sufficient contact area, guaranteeing the accuracy and sufficient connection time when the first and second contacts are connected to the contacts of the image forming apparatus.

[0079] In one possible implementation, the image forming apparatus includes multiple contacts. When the consumable material leaves a designated position in the image forming apparatus, each contact moves along a different preset displacement trajectory on the consumable chip body 110. That is, the consumable chip body 110 includes multiple preset displacement trajectories. In a specific implementation, the multiple contacts of the image forming apparatus can be arranged in parallel along a vertical direction. In this case, the preset displacement trajectories of each contact on the consumable chip body 110 have similar shapes.

[0080] In one possible implementation, such as Figure 2 As shown, the first contact 120 includes a first power contact (VoltCurrentCondenser, VCC) 121, a data signal contact (Serial Data, SDA) 122, a first ground contact (GND) 123, and a clock signal contact (Clock, CLK) 124, and the second contact 130 includes a signal output contact 131, a second ground contact 132, and a second power contact 133.

[0081] In specific implementation, since the starting point of the contact of the image forming apparatus moving along the preset displacement trajectory on the consumable chip body 110 during the process of the consumable leaving the designated position of the image forming apparatus is the first contact 120, the first contact 120 is also distributed on the preset displacement trajectory, and the first power contact 121, data signal contact 122, first ground contact 123, and clock signal contact 124 of the first contact 120 are respectively distributed on different preset displacement trajectories. When the consumable is installed in the designated position of the image forming apparatus, each contact of the first contact 120 is electrically connected to the corresponding contact of the image forming apparatus to form a first information transmission channel.

[0082] Similarly, the signal output contact 131, the second ground contact 132, and the second power contact 133 are also distributed on different preset displacement trajectories, so as to electrically connect with the corresponding contact of the image forming device when the consumable leaves the designated position of the image forming device, thereby forming a second information transmission channel.

[0083] In one possible implementation, the second grounding contact 132 and the first grounding contact 123 can be distributed on the same preset displacement trajectory, so that when the grounding contact of the image forming apparatus moves along the preset displacement trajectory, it can be electrically connected to the second grounding contact and the first grounding contact respectively, without having to set an additional grounding contact on the image forming apparatus, thus reducing the complexity of the circuit structure design.

[0084] In one possible implementation, based on the contacts included in the first contact 120, the image forming apparatus may be correspondingly provided with a first connecting contact, a second connecting contact, a third connecting contact, and a fourth connecting contact. When the consumable is installed at a designated position of the image forming apparatus, the first connecting contact can be electrically connected to the first power contact 121, the second connecting contact can be electrically connected to the data signal contact 122, the third connecting contact can be electrically connected to the first ground contact 123, and the fourth connecting contact can be electrically connected to the clock signal contact 124. When the consumable is displaced and the contacts of the image forming apparatus are electrically connected to the second contact 130, in addition to the third connecting contact being electrically connected to the second ground contact 132, the signal output contact 131 and the second power contact 133 in the second contact 130 can be electrically connected to any different contacts of the image forming apparatus. For example, signal output contact 131 can be electrically connected to the first power contact, and the second power contact 133 can be electrically connected to the second power contact. This also indicates that signal output contact 131 and the first power contact 121 are distributed on the same preset displacement trajectory, and the second power contact 133 and the data signal contact 122 are distributed on the same preset displacement trajectory; or signal output contact 131 can be electrically connected to the first power contact, and the second power contact 133 can be electrically connected to the fourth power contact. This also indicates that signal output contact 131 and the second power contact 122 are distributed on the same preset displacement trajectory. Point 131 and the first power contact 121 are distributed on the same preset displacement trajectory, and the second power contact 133 and the clock signal contact 124 are distributed on the same preset displacement trajectory; or the signal output contact 131 can be electrically connected to the second connecting contact, and the second power contact 133 can be electrically connected to the fourth connecting contact. This situation also indicates that the signal output contact 131 and the data signal contact 122 are distributed on the same preset displacement trajectory, and the second power contact 133 and the clock signal contact 124 are distributed on the same preset displacement trajectory. Alternatively, signal output contact 131 can be electrically connected to the second connected contact, and the second power contact 133 can be electrically connected to the first connected contact. This situation also indicates that signal output contact 131 and data signal contact 122 are distributed on the same preset displacement trajectory, and the second power contact 133 and the first power contact 121 are distributed on the same preset displacement trajectory; or signal output contact 131 can be electrically connected to the fourth connected contact, and the second power contact 133 can be electrically connected to the first connected contact. This situation also indicates that signal output contact 131... The first power contact 121 and the clock signal contact 124 are distributed on the same preset displacement trajectory, and the second power contact 133 and the first power contact 121 are distributed on the same preset displacement trajectory; or the signal output contact 131 can be electrically connected to the fourth connected contact, and the second power contact 133 can be electrically connected to the second connected contact. This situation also indicates that the signal output contact 131 and the clock signal contact 124 are distributed on the same preset displacement trajectory, and the second power contact 133 and the data signal contact 122 are distributed on the same preset displacement trajectory.

[0085] In one possible implementation, if the consumable is installed to the designated position of the image forming apparatus along a preset displacement trajectory, during the installation and movement process, the contacts of the image forming apparatus can first be electrically connected to the second contact 130, and then electrically connected to the first contact 120. For example, during the process of installing the consumable to the designated position of the image forming apparatus along the preset displacement trajectory, i.e., during the movement of the consumable, the second contact can first be electrically connected to the signal output contact 131, and then electrically connected to the data signal contact 122; the third contact can first be electrically connected to the second ground contact 132, and then electrically connected to the first ground contact 123; the fourth contact can first be electrically connected to the second power contact 133, and then electrically connected to the clock signal contact 124. Since the second contact does not have a corresponding contact on the preset displacement trajectory corresponding to the first contact, the first contact is only electrically connected to the first power contact 121.

[0086] Corresponding to the above embodiment, during the process of the consumable leaving the designated position of the image forming apparatus along the preset displacement trajectory, the contacts of the image forming apparatus change from being electrically connected to the first contact 120 to being electrically connected to the second contact 130. For example, during the process of the consumable leaving the designated position of the image forming apparatus along the preset displacement trajectory, the second contact changes from being electrically connected to the data signal contact 122 to being electrically connected to the signal output contact 131, the third contact changes from being electrically connected to the first ground contact 123 to being electrically connected to the second ground contact 132, and the fourth contact changes from being electrically connected to the clock signal contact 124 to being electrically connected to the second power contact 133. Since the second contact does not have a corresponding contact on the preset displacement trajectory of the first contact, the first contact simply leaves the first power contact 121 and moves along the preset displacement trajectory.

[0087] In one possible implementation, the preset displacement trajectory of the contacts of the image forming apparatus on the consumable chip body 110 is as follows: Figure 3 As shown, the preset displacement trajectory of the first contact point on the consumable chip body 110 is the first preset displacement trajectory 141, the preset displacement trajectory of the second contact point on the consumable chip body 110 is the second preset displacement trajectory 142, the preset displacement trajectory of the third contact point on the consumable chip body 110 is the third preset displacement trajectory 143, and the preset displacement trajectory of the fourth contact point on the consumable chip body 110 is the fourth preset displacement trajectory 144. The first contact point 120 and the second contact point 130 can be correspondingly positioned at both ends of these trajectories.

[0088] It should be noted that, Figure 3 The preset displacement trajectory shown is merely an illustrative example and should not be construed as limiting the scope of protection of this application. In practice, users can design the shape of the preset displacement trajectory according to their needs.

[0089] In practical applications, to reduce the impact caused by power instability and grounding when the second information transmission channel is activated and to ensure the stability of the detection signal, it is necessary to ensure that the contacts of the image forming apparatus, when electrically connected to the second contact 130, are last connected to the signal output contact 131. That is, grounding and power supply are prioritized before the specific detection signal is output. Since the embodiments of this application are mainly for detecting whether the consumable has been displaced, that is, whether the consumable has been disassembled or moved after being installed in the designated position of the image forming apparatus, it is necessary to ensure that during the process of the consumable leaving the designated position of the image forming apparatus along a preset displacement trajectory, the contacts of the image forming apparatus, when electrically connected to the second contact 130, are last connected to the signal output contact 131.

[0090] In one possible implementation, as the consumable 100 moves away from the designated position along a preset displacement trajectory, the contact of the image forming apparatus moves away from the contact area of ​​the first contact and moves along the preset displacement trajectory on the consumable chip body 110. It can first complete the electrical connection with the first ground contact 132, then complete the electrical connection with the first power contact 133, and finally complete the electrical connection with the signal output contact 131.

[0091] In another possible implementation, as the consumable 100 moves away from the designated position along a preset displacement trajectory, the contact of the image forming apparatus moves away from the contact area of ​​the first contact and along the preset displacement trajectory on the consumable chip body 110. At the same time, the electrical connection with the first ground contact 132 and the first power contact 133 can be completed simultaneously, and then the electrical connection with the signal output contact 131 can be completed.

[0092] That is, when the contact of the image forming apparatus is electrically connected to the signal output contact 131, the first ground contact 132 and the first power contact 133 are also electrically connected to the contact of the image forming apparatus.

[0093] In specific implementation, when the consumable leaves the designated position of the image forming apparatus along the preset displacement trajectory, that is, when the consumable is displaced, the corresponding contact of the image forming apparatus also moves from the first contact to the second contact on the consumable chip along the preset displacement trajectory. Therefore, the electrical connection sequence between the contact of the image forming apparatus and each contact in the second contact can be adjusted by changing the setting position or contact area of ​​the second contact 130 on the consumable chip body 110.

[0094] See Figure 4 This is a schematic diagram illustrating the positional layout of a second contact point on the consumable chip body, provided in an embodiment of this application. Figure 4As shown in (a), the minimum distance X1 between the first ground contact 132 and the first contact is less than the minimum distance X2 between the first power contact 133 and the first contact, and less than the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming apparatus moves from the first contact 120 to the second contact 130, it will first complete the electrical connection with the first ground contact 132, then complete the electrical connection with the first power contact 133, and finally complete the electrical connection with the signal output contact 131. Or as... Figure 4 As shown in (b), the minimum distance X1 between the first grounding contact 132 and the first contact is equal to the minimum distance X2 between the first power contact 133 and the first contact, which is less than the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming apparatus moves from the first contact to the second contact, it will first complete the electrical connection with the first grounding contact 132 and the first power contact 133 simultaneously, and then complete the electrical connection with the signal output contact 131.

[0095] See Figure 5 This is a schematic diagram illustrating the contact area layout of a second contact point on the consumable chip body, provided in an embodiment of this application. Figure 5 As shown in (a), the contact area of ​​the first ground contact 132 is greater than the contact area of ​​the first power contact 133, which is greater than the contact area of ​​the signal output contact 131. This means that the minimum distance X1 between the first ground contact 132 and the first contact is less than the minimum distance X2 between the first power contact 133 and the first contact, which is less than the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming apparatus moves from the first contact to the second contact, it first completes the electrical connection with the first ground contact 132, then the electrical connection with the first power contact 133, and finally the electrical connection with the signal output contact 131. Or as... Figure 5 As shown in (b), the contact area of ​​the first grounding contact 132 is greater than the contact area of ​​the first power contact 133 and the contact area of ​​the signal output contact 131. Correspondingly, the minimum distance X1 between the first grounding contact 132 and the first contact is equal to the minimum distance X2 between the first power contact 133 and the first contact and the minimum distance X3 between the signal output contact 131 and the first contact. Therefore, when the contact of the image forming apparatus moves from the first contact to the second contact, it will first complete the electrical connection with the first grounding contact 132 and the first power contact 133 simultaneously, and then complete the electrical connection with the signal output contact 131.

[0096] Of course, in specific implementations, the contact area can be arranged in other ways, such as aligning the center lines of each contact area. This application embodiment does not make specific requirements in this regard, as long as it is ensured that when the contact of the image forming apparatus moves from the first contact to the second contact, it is finally connected to the signal output contact 131.

[0097] In one possible implementation, when the image forming apparatus has multiple contacts, the electrical connection sequence between each contact of the image forming apparatus and each contact in the second contact can be adjusted by changing the arrangement position or contact area of ​​each contact. For specific configuration methods, please refer to... Figure 4 and Figure 5 The embodiments shown are described in detail below for the sake of brevity.

[0098] It should be noted that when adjusting the electrical connection sequence between each contact of the image forming apparatus and each contact in the second contact by changing the setting position or contact area of ​​each contact of the image forming apparatus, the setting position or contact area of ​​each contact in the first contact needs to be adjusted accordingly to ensure that when the consumable is installed in the designated position of the image forming apparatus, each contact of the image forming apparatus and each contact in the first contact are in an electrically connected state.

[0099] In one possible implementation, such as Figure 6 As shown, the area of ​​the signal output contact 131 on the preset displacement trajectory determines the output time of the specific detection signal. If the area of ​​the signal output contact 131 is too small, the output time of the specific signal will be too short, and an effective specific detection signal cannot be obtained. Therefore, the area of ​​the signal output contact 131 on the preset displacement trajectory needs to be greater than the set area threshold so that the electrical connection time between the contact of the image forming apparatus and the signal output contact 131 is greater than the set time threshold during the process of the consumable 100 leaving the designated position of the image forming apparatus. This avoids the situation where the output time of the specific detection signal is too short and the signal cannot be detected due to the user moving the consumable too fast.

[0100] In practice, the area threshold can be set according to a multiple of the period required for the output of a specific detection signal; however, this application does not make specific requirements in this regard.

[0101] Of course, in practical applications, the output time of a specific detection signal can also be increased by increasing the area of ​​the contact of the image forming apparatus electrically connected to the signal output contact 131 in the preset displacement trajectory direction. That is, the area of ​​the contact of the image forming apparatus electrically connected to the signal output contact 131 in the preset displacement trajectory direction needs to be greater than a set area threshold. Alternatively, the output time of the specific detection signal can be guaranteed by simultaneously increasing the area of ​​the signal output contact 131 in the preset displacement trajectory and the area of ​​the contact of the image forming apparatus electrically connected to the signal output contact 131 in the preset displacement trajectory direction. This application embodiment does not make specific requirements in this regard.

[0102] In some embodiments, by setting the area of ​​the signal output contact 131 on the preset displacement trajectory to be greater than a set area threshold and setting the area of ​​the contact corresponding to the image forming apparatus electrically connected to the signal output contact 131 to be greater than the set area threshold, the effective contact time between the signal output contact 131 and the contact corresponding to the image forming apparatus can be longer, thereby ensuring that the output time of a specific detection signal is long enough.

[0103] In one possible implementation, the image forming apparatus can form a first series of contact points, a second series of contact points, a third series of contact points, and a fourth series of contact points via the contact spring 200, such as... Figure 7 As shown, each contact spring 200 represents a connection contact point. When the consumable 100 moves along a preset displacement trajectory, the contact spring 200 moves along the corresponding preset displacement trajectory on the consumable chip body 110. Specifically, during the process of the consumable 100 being installed to the designated position of the image forming apparatus along the preset displacement trajectory, each contact spring 200 first connects to the second contact 130 and then to the first contact 120 along the corresponding preset displacement trajectory. During the process of the consumable leaving the designated position of the image forming apparatus along the preset displacement trajectory, each contact spring 200 moves from the first contact 120 to the second contact 130 along the corresponding preset displacement trajectory.

[0104] See Figure 8 Figure 1 is a schematic diagram of the process by which a consumable material leaves a designated position of an image forming apparatus along a preset displacement trajectory, provided in this application. (a) Figure 2 is a schematic diagram of the first contact of the contact spring 200 and the consumable chip 100 being electrically connected when the consumable material is installed at the designated position of the image forming apparatus. (b) Figure 3 is a schematic diagram of the contact spring 200 sliding on the consumable chip 100 along the preset displacement trajectory when the consumable material is being disassembled. (c) Figure 4 is a schematic diagram of the contact spring 200 and the consumable chip 100 after the consumable material is disassembled.

[0105] In this embodiment, the first contact and the second contact are set on a preset displacement trajectory of the contact of the image forming apparatus on the consumable chip body, so that as the consumable moves, the contact of the image forming apparatus naturally connects with the first contact and the second contact, thereby detecting the disassembly or movement of the consumable. The above structural setting realizes the detection of consumable displacement, which reduces the additional structural design and circuit design compared with the prior art.

[0106] In another possible implementation, the contacts of the image forming apparatus can be set as raised contacts, which move along a preset displacement trajectory on the consumable chip. Here, one raised contact represents a connecting contact.

[0107] In practical applications, the first and second contacts can also be set as raised contacts. The raised first and second contacts can achieve electrical connection with the contacts of the image forming apparatus. In this case, the raised second contact can form a movement trajectory on the image forming apparatus. Correspondingly, the first contact is set on the consumable chip at a position corresponding to the movement trajectory.

[0108] In practice, users can also set other styles of touch points, but this application embodiment does not make specific requirements for this.

[0109] In one possible implementation, the consumable chip is also provided with a detection circuit for electrically connecting to the second contact 130, and for outputting a specific detection signal through the signal output contact 131 when the second contact 130 is electrically connected to the contact of the image forming apparatus.

[0110] See Figure 9 This is a schematic diagram of the circuit structure of a detection circuit provided in an embodiment of this application. Figure 9 As shown, the detection circuit includes a Pierce oscillator 150, which has three circuit ports that are electrically connected to a signal output contact 131, a first ground contact 132, and a first power contact 133, respectively.

[0111] In practical applications, the Pierce oscillator 150 is an electronic oscillation circuit, which is particularly suitable for generating oscillation signals with specific characteristics in conjunction with a quartz crystal. The Pierce oscillator 150 has a stable oscillation frequency, a simple circuit structure, and low cost. Therefore, using the Pierce oscillator 150 in a detection circuit can reduce the cost of the detection circuit.

[0112] In specific implementation, such as Figure 10 As shown, the Pierce oscillator 150 requires very few components, including an inverter U, a resistor R, a quartz crystal X, and capacitors C1 and C2. The quartz crystal X, along with capacitors C1 and C2, forms a π-type network bandpass filter, providing a 180° phase shift and the required voltage gain at approximately the resonant frequency of the quartz crystal. At the oscillation frequency, the quartz crystal X exhibits inductive behavior and can be considered as a high-Q inductor. The 180° phase shift of the π-type network, combined with the negative gain of the inverter U, results in a positive loop gain, causing the bias voltage set by the resistor R to become unstable, leading to oscillation output. The output frequency is equal to the oscillation frequency of the quartz crystal X. Therefore, the output frequency of the oscillator can be changed by altering the oscillation frequency of the quartz crystal X.

[0113] Of course, in practical applications, other signal generation circuits can also be used as detection circuits to output specific detection signals, and this application embodiment does not make specific requirements in this regard.

[0114] In specific implementation, when the contact of the image forming apparatus, such as the contact spring, is electrically connected to the second contact, such as Figure 3 As shown, the contact of the image forming apparatus moves from the clock signal contact 124 to the first power contact 133, from the second ground contact 123 to the first ground contact 132, and from the data signal contact 122 to the signal output contact 131. At this time, the signal output contact 131 will output a detection signal with specific characteristics (such as specific frequency, period, and voltage). Simultaneously, the image forming apparatus detects the received signal in real time. If a detection signal with specific characteristics is detected, i.e., a specific detection signal, it is determined that the consumable has been displaced. If no detection signal with specific characteristics is detected, it is determined that the consumable has not been displaced.

[0115] This application embodiment detects whether the consumable has shifted by using a specific detection signal. Compared with a simple high-level or low-level signal, it is more identifiable, avoids detection errors, and enhances the reliability of the detection results.

[0116] In specific implementation, such as Figure 11 As shown, the control panel of the image forming apparatus is equipped with a System on Chip (SOC). The SOC's SDA port and data input / output (I / O) port are electrically connected to the SDA port of the control panel for receiving signals input from the SDA port of the control panel and for controlling the SDA port of the control panel. The SOC's CLK port is electrically connected to the CLK port of the control panel for outputting a clock signal through the CLK port of the control panel. The GND port of the control panel is electrically connected to the first ground contact 132 to provide a ground signal for the consumable chip 100. The CLK port of the control panel is electrically connected to the first power contact 133 to provide a power signal for the consumable chip 100. The SDA port of the control panel is electrically connected to the signal output contact 131 to receive a specific detection signal output by the signal output contact 131.

[0117] In practical applications, to avoid confusion with communication signals from other ports, this embodiment of the application determines whether the consumable has shifted by detecting a specific signal on the IO port of the SOC. Therefore, when the specific detection signal output by the signal output contact 131 is sent back to the SDA port, CLK port, or VCC port of the control panel, the IO port will be electrically connected to the corresponding SDA port, CLK port, or VCC port of the control panel to achieve the purpose of receiving the specific detection signal on the IO port and detecting the displacement of the consumable through the specific detection signal.

[0118] In this embodiment, the detection circuit is placed on the consumable chip, which can save on additional structural design. Furthermore, the detection circuit can share electrical connection lines with the consumable chip, thus also saving on electrical connection lines.

[0119] Corresponding to the above embodiments, this application provides a consumable, including as follows: Figures 1 to 11 The consumable chip of the embodiment shown.

[0120] In specific implementations, when the image forming apparatus is a monochrome printer, the consumables can be directly installed on the image forming apparatus, and the consumable chip on the consumable is connected to the contacts of the image forming apparatus, such as contact springs. When the image forming apparatus is a color printer, multiple consumables can be provided. In one embodiment, the image forming apparatus is provided with four consumables. In this case, the consumables can be installed in a sliding drawer of the image forming apparatus, and the consumables are installed on the image forming apparatus by sliding the drawer. Figure 12 As shown. The consumable chip 100 is mounted on the consumable 300, and the consumable 300 is mounted on the sliding drawer 400. The consumable 300 moves within the image forming apparatus by pushing and pulling the sliding drawer 400, thereby achieving electrical connection between the first and second contacts of the consumable chip and the contacts of the image forming apparatus.

[0121] like Figure 13 As shown, after the four consumables 300 are installed on the sliding drawer 400, they are installed to the designated position of the image forming apparatus via the sliding drawer 400. At this time, the first contact point is in contact with the contact spring 200 of the image forming apparatus, realizing printing communication with the image forming apparatus. When the sliding drawer is moved, causing the consumables to leave the designated position, the contact spring 200 of the image forming apparatus will leave the first contact point and move along a preset displacement trajectory on the consumable chip body, thereby making contact with the second contact point. At this time, consumable chip 100 and image forming apparatus realize consumable displacement detection communication.

[0122] Specifically, such as Figure 14 As shown, taking one of the four consumables as an example, during the process of the consumable 300 being disassembled from the designated position, the positional relationship between the contact spring 200 and the consumable changes from Figure (a) to Figure (b). During this process, the contact spring 200 will move along a preset displacement trajectory on the consumable chip body and make contact with the second contact point to obtain a specific detection signal, and determine whether the consumable has been displaced based on the specific detection signal.

[0123] In practical implementation, when there are four consumables, a microcontroller unit (MCU) can be set in the image forming apparatus. The MCU is electrically connected to each consumable to receive specific detection signals sent by each consumable, such as... Figure 15 As shown in the diagram. The MCU can be configured with only one power supply port (VCC) and one ground port (GND) for electrical connection to each consumable. For other port settings and circuit connection configurations of the MCU, please refer to [reference needed]. Figure 11The circuit shown is not described in detail here for the sake of brevity.

[0124] Meanwhile, other specific details of the embodiments of this application can be found in the description of the above consumable chip embodiments, which will not be repeated here for the sake of brevity.

[0125] It should be noted that, Figure 15 In the diagram, the dashed arrows on each consumable chip can represent the preset displacement trajectory of the contacts of the image forming apparatus on the chip body, or they can represent the specific detection signal output by the detection circuit and transmitted back to the image forming apparatus when the contacts of the image forming apparatus are electrically connected to the corresponding contacts of the detection circuit (signal output contact, second ground contact, and second power contact). However, it should be noted that... Figure 15 The dashed arrows in the text are merely illustrative and are not intended to limit the scope of protection of the embodiments of this application.

[0126] Corresponding to the above embodiments, this application provides an image forming apparatus, including the consumable chip or consumable of the above embodiments.

[0127] Corresponding to the above embodiments, this application provides a method for detecting the displacement of consumables, applied to an image forming apparatus. The consumables included in the image forming apparatus are those described in the above embodiments. When the consumables leave a designated position in the image forming apparatus, the image forming apparatus is electrically connected to a second contact. Figure 16 As shown, the detection method includes:

[0128] S1601: Receives a specific detection signal from the second contact;

[0129] S1602: Determine whether a specific detection signal is consistent with a preset detection signal;

[0130] S1603: If the specific detection signal is consistent with the preset detection signal, it is determined that the consumable has been displaced.

[0131] In this embodiment, a preset detection signal can be set based on the oscillation signal of the Pierce oscillator. When the image forming apparatus receives the specific detection signal, it compares the specific detection signal with the preset detection signal. If the specific detection signal matches the preset detection signal, it is determined that the consumable has shifted. In a specific embodiment, to prevent signal interference from the SDA and CLK of the consumable itself, the frequency design of the detection circuit must be clearly distinguishable from the normal operating frequency of the SDA and CLK of the consumable. When the consumable does not shift, the image forming apparatus cannot detect the specific frequency signal. When the consumable shifts, the detection circuit is electrically connected to the contacts of the image forming apparatus through the second contact. At this time, the detection signal is transmitted back to the SOC of the image forming apparatus through the SDA, CLK, or VCC port. The SOC only needs to determine whether the frequency characteristics of the specific detection signal are the frequency designed for the detection circuit. If so, it is determined that the consumable has shifted. This embodiment determines that shift has occurred by detecting a signal with frequency characteristics. Compared with the method of detecting high and low levels, this method is more reliable and accurate, and can reduce the occurrence of unclear signals and false triggers.

[0132] In one possible implementation, the image forming apparatus determines whether a specific detection signal meets expectations. If the specific detection signal matches a preset detection signal, and it is determined that the specific detection signal meets expectations, then it is determined that the drawer or consumable has been pushed forward and / or pulled out relative to the frame of the image forming apparatus, and the number of times the drawer or consumable has been pushed forward and / or pulled out relative to the frame of the image forming apparatus is counted. This configuration allows for the determination of whether color registration correction needs to be performed based on the number of times the drawer or consumable has been pushed forward or pulled out, thus enabling timely color registration correction and improving the quality of the printed image.

[0133] Other specific details of the embodiments of this application can be found in the description of the consumable chip and consumable embodiments above. For the sake of brevity, they will not be repeated here.
