Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing imaging, in particular to a consumable chip and a consumable cartridge. BACKGROUND

[0002] In the printing imaging process, the printing device 1 needs the assistance of the imaging auxiliary information of the consumable cartridge to complete the imaging process. The imaging auxiliary information of the printing device 1 is recorded not only in the printing device 1 but also on the consumable chip. The consumable chip can be installed on the consumable cartridge, which can be an ink cartridge filled with ink or a toner cartridge filled with toner. The ink cartridge and the toner are recording materials, and the function of the consumable chip is to control the authentication and data matching between the consumable cartridge and the printing device 1, and to provide imaging auxiliary information in the subsequent imaging process. The consumable chip is provided with a wafer and a terminal for realizing electrical connection with the stylus of the printing device 1, which includes a chip select terminal for controlling the data read and write operation of the consumable cartridge. The wafer stores toner amount information, manufacturer information, serial number and other related information.

[0003] The consumable chip described in patent application 201410522659.3 does not need a chip select terminal, which avoids many hidden troubles caused by using a chip select signal (RST) to control the read and write operation, such as chip select signal jump caused by signal interference or poor contact, which in turn causes data communication interruption, error or data damage and other problems. However, this method needs to read and write data information according to the clock signal sent by the printing device 1. Once the printing device 1 is upgraded, the consumable chip cannot correctly write or read data information if the read and write operation cannot be performed according to the regularity of the clock signal. In addition, after the printing device 1 is upgraded, the chip select terminal needs to be re-set on the consumable chip to enable the consumable chip to normally communicate with the printing device 1, which will involve the recycling of the consumable chip, increasing the time and recycling cost. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a consumable chip and a consumable cartridge, which improves the anti-upgrade performance of the consumable chip and reduces the recycling cost of the consumable chip.

[0005] In a first aspect, the embodiments of the present application provide a consumable chip for communicating with a printing device, comprising a first communication plane and a second communication plane, a first communication terminal is arranged on the first communication plane, and a second communication terminal is arranged on the second communication plane, the number of the first communication terminal and the second communication terminal is different, the first communication terminal is used for communicating with the printing device before the printing device is upgraded; and the second communication terminal is used for communicating with the printing device after the printing device is upgraded. The consumable chip of the present application can improve the anti-upgrade performance, reduce the recycling cost and realize the rapid switching of user demand scenarios.

[0006] In one possible implementation, the consumable chip includes a first substrate, on which an electronic module and a first communication terminal electrically connected to the electronic module are disposed, the first communication terminal not including a second terminal; the consumable chip also includes a bending portion, one end of which is disposed on the first substrate and the other end of which can be flipped relative to the first substrate, the bending portion being provided with a second terminal, the second terminal being electrically connected to the electronic module.

[0007] The consumable chip of this application has a reversible bendable portion on a first substrate. The bendable portion has a second terminal that is electrically connected to the electronic module of the first substrate. When the printing device 1 is not upgraded, the bendable portion is not flipped, and communication with the printing device 1 is achieved through the first substrate and the first communication terminal on the first substrate. This solves many hidden dangers caused by using the chip select signal (RST) to control read and write operations, such as signal interference or poor contact causing chip select signal jumps, which can lead to data communication interruption, errors, or data corruption. When the printing device 1 is upgraded, the bendable portion is flipped, and communication with the printing device 1 is achieved simultaneously through the second terminal on the bendable portion and the first communication terminal on the first substrate (which together constitute the second communication terminal), in order to cope with the upgrade of the printing device 1. The consumable chip of this application can switch between different numbers of terminals to form an electrical connection with the printing device 1. In other words, it can achieve rapid switching of user needs.

[0008] In one possible implementation, the first communication terminal includes at least one of a data terminal, a power terminal, a clock terminal, and a ground terminal.

[0009] In one possible implementation, the second terminal includes a chip select terminal.

[0010] In one possible implementation, the bent portion is detachably or fixedly disposed on the first substrate.

[0011] In one possible implementation, the bending portion includes a first structure and a second structure that can be flipped and connected. The first structure is disposed on a first substrate, and the second structure is provided with a second terminal. The second terminal does not contact the adapter pin of the printing device in a first state, but contacts the adapter pin of the printing device in a second state.

[0012] In one possible implementation, the first substrate includes a first plane and a second plane, the first plane and the second plane being disposed opposite to each other, a first communication terminal being disposed on the first plane, and a first structure being disposed on the second plane. In a first state, the second terminal of the second structure does not contact the adapter pin of the printing device; in a second state, the second structure is flipped toward the first plane, so that the second terminal contacts the adapter pin of the printing device.

[0013] In one possible implementation, the first substrate includes a first plane and a second plane, the first plane and the second plane being disposed opposite to each other, a communication terminal being disposed on the first plane, and a first structure being disposed on the first plane. In a first state, the second terminal of the second structure does not contact the adapter pin of the printing device; in a second state, the second structure is flipped toward the first plane, so that the second terminal contacts the adapter pin of the printing device.

[0014] In one possible implementation, the first and second structures of the bending portion are flexibly connected.

[0015] In one possible implementation, the first and second structures of the bent portion are hinged together.

[0016] In one possible implementation, the bent portion is disposed on the first substrate by magnetic attraction, welding or adhesive bonding.

[0017] Secondly, this application provides a consumable cartridge including a consumable chip for communicating with a printing device. The chip includes a first communication plane and a second communication plane. A first communication terminal is disposed on the first communication plane, and a second communication terminal is disposed on the second communication plane. The number of the first and second communication terminals differs. The first communication terminal is used for communication with the printing device before an upgrade; the second communication terminal is used for communication with the printing device after an upgrade. This consumable cartridge, through its consumable chip, can improve upgrade resistance, reduce recycling costs, and enable rapid switching between user needs. Attached Figure Description

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] See Figure 1 In the prior art, the printing device 1 is provided with a communication port 10, and the prior art chip 21' is provided with an interface module 20. A communication link is established between the communication port 10 and the interface module 20, and the printing device 1 and Figure 4 , Figure 5The prior art consumable chip 21' on the consumable cartridge 2 can transmit information via a communication link. For example, during imaging, the prior art consumable chip 21' is used to provide identification information and information on the usage status of recording materials (such as ink cartridges or toner). When the printing device 1 sends a signal to the prior art consumable chip 21', the printing device 1 is the sender and the prior art consumable chip 21' is the receiver; conversely, when the prior art consumable chip 21' sends a signal to the printing device 1, the prior art consumable chip 21' is the sender and the printing device 1 is the receiver. The information transmission process between the printing device 1 and the prior art consumable chip 21' is achieved through physical electrical contact between the stylus on the printing device 1 and the contact portion on the prior art consumable chip 21'.

[0050] like Figure 2 As shown, the printing device 1 includes a stylus holder 11, which includes an upper stylus holder surface 111 along the Y-axis and a front stylus holder surface 112 along the X-axis. It also includes a first stylus 1101, a second stylus 1102, a third stylus 1103, a fourth stylus 1104, and a fifth stylus 1105. Preferably, the first stylus 1101, the second stylus 1102, the third stylus 1103, the fourth stylus 1104, and the fifth stylus 1105 are respectively a data stylus, a chip select stylus, a clock stylus, a power stylus, and a ground stylus, respectively, and interact with the printer during printing. Figure 4 The existing consumable chip 21' has a data contact SDA, a chip select contact RST, a clock contact SCL, a power contact VCC, and a ground contact GND.

[0051] Printing device 1 sends data signals to the existing consumable chip 21' via the data contact SDA, sends a chip select signal to the existing consumable chip 21' via the chip select contact RST, sends periodic, alternating, or repetitive low-level and high-level clock signals to the existing consumable chip 21' via the clock contact SCL, provides operating voltage to the existing consumable chip 21' via the power contact VCC, and provides a unified reference low level for receiving and transmitting data between printing device 1 and the existing consumable chip 21' via the ground contact GND, ensuring the correctness and stability of the communication process.

[0052] like Figure 3As shown, the first contact pin 1101 includes a first contact pin tip 11011, a first contact pin front end 11012, a first contact pin bevel end 11013, and a first contact pin tip 11014, all of which can form contact with the terminals on the consumable chip for electrical connection. In this way, the consumable chip in the consumable cartridge can communicate with the printing device 1 via the contact pins. In the prior art, the first contact pin 1101, the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104, and the fifth contact pin 1105 all make contact with the data contact SDA, chip select contact RST, clock contact SCL, power contact VCC, and ground contact GND of the communication terminals of the consumable chip through their contact pin tips, respectively.

[0053] Existing technology discloses a consumable chip that does not require a chip select terminal, avoiding many potential problems caused by using a chip select signal (RST) to control read and write operations, such as signal interference or poor contact leading to chip select signal jumps, which can cause data communication interruptions, errors, or data corruption. However, this method requires data reading and writing operations to follow the clock signal's variation. If the printer 1 is upgraded and can no longer perform read and write operations based on the clock signal's variation, the proposed solution will cause the consumable chip to fail to correctly write or read data. In addition, after the printer 1 is upgraded, the chip select terminal on the consumable chip needs to be reconfigured to enable the consumable chip to communicate normally with the printer 1, which involves the recycling of the consumable chip, increasing time and recycling costs.

[0054] To address these issues, a first aspect of this application provides a consumable chip 21, including a first substrate 210. An electronic module 21021 and a first communication terminal electrically connected to the electronic module 21021 are disposed on the first substrate 210. The first communication terminal does not include a second terminal. The consumable chip also includes a bending portion 211, one end of which is disposed on the first substrate 210, and the other end of which can be flipped relative to the first substrate 210. A chip select terminal 21012 is disposed on the bending portion 211, and the chip select terminal 21012 is electrically connected to the electronic module 21021. The consumable chip 21 of this application has a foldable bend 211 on the first substrate 210. The bend 211 has a chip select terminal 21012 that is electrically connected to the electronic module of the first substrate 210. When the printing device 1 is not upgraded, the bend 211 is not flipped, and communication with the printing device 1 is achieved through the first substrate 210 and the first communication terminal on the first substrate 210. This can solve many hidden dangers caused by using the chip select signal (RST) to control read and write operations, such as signal interference or poor contact causing chip select signal jumps, which can lead to data communication interruption, errors or data corruption. When the printing device 1 is upgraded, the bend 211 is flipped, and communication with the printing device 1 is achieved simultaneously through the chip select terminal 21012 on the bend 211 and the first communication terminal on the first substrate 210 (which constitutes the second communication terminal) to cope with the upgrade of the printing device 1. The consumable chip 21 of this application can switch between different numbers of terminals to form an electrical connection with the printing device 1. In other words, it can achieve rapid switching of user needs.

[0055] The specific structure and function of the consumable chip provided in the embodiments of this application will be further described below with reference to the text and accompanying drawings.

[0056] See Figures 6-7According to the first aspect of the present application, the consumable chip 21 includes a first substrate 210 and a bending portion 211. The first substrate 210 includes a first plane 2101 and a second plane 2102 disposed opposite to the first plane 2101. The first plane 2101 includes at least one first communication terminal. Preferably, the first communication terminal includes a first terminal 21011, a third terminal 21013, a fourth terminal 21014, and a fifth terminal 21015. Preferably, the second plane 2102 includes an electronic module 21021. The first terminal 21011, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 are electrically connected to the electronic module 21021 through wires or vias. The bending portion 211 includes a first structure 2111 and a second structure 2112. The first structure 2111 is disposed on the first substrate 210, and the second structure 2112 includes a second terminal 21012. Specifically, the second terminal 21012 is a chip select terminal, which is electrically connected to the electronic module 21021 through a wire and / or via on the bending portion. Preferably, the first structure 2111 is disposed on the second plane 2102. The second structure 2112 does not contact the chip select pin of the printing device 1 in the first state, and contacts the chip select pin of the printing device 1 in the second state. Specifically, in the first state of the second structure 2112, the second terminal 21012 does not contact the pin of the printing device 1, especially not the chip select pin; in the second state, the projection of the second structure 2112 overlaps with the projection of the first substrate 210 (in the direction perpendicular to the first substrate 210), and the second terminal 21012 can contact the chip select pin of the printing device 1. The first state changes to the second state, that is, the second structure 2112 bends and flips in the direction of the first plane 2101, so that the second terminal 21012 contacts the chip select pin of the printing device 1.

[0057] It is understandable that when the printing device 1 is in an un-upgraded state (corresponding to the first state), the bending section 211 is not flipped, and communication with the printing device 1 is achieved using the first substrate 210 and the first communication terminals (first terminal 21011, third terminal 21013, fourth terminal 21014, and fifth terminal 21015) disposed on the first substrate 210. This can solve many potential problems caused by using the chip select signal (RST) to control read and write operations, such as signal interference or poor contact leading to chip select signal jumps, which in turn cause data communication interruptions, errors, or data corruption. When the printing device 1 is upgraded (corresponding to the second state), the bending section 211 is flipped, and the second structure 2112 is transferred from the first substrate 210... The back side (second plane 2102) is flipped to the front side (first plane 2101), so that the chip select terminal (second terminal 21012) and the first communication terminal (first terminal 21011, third terminal 21013, fourth terminal 21014 and fifth terminal 21015) on the first substrate 210 communicate with the printing device 1 together (at this time, the second terminal 21012, first terminal 21011, third terminal 21013, fourth terminal 21014 and fifth terminal 21015 constitute the second communication terminal) to cope with the upgrade of the printing device 1. The consumable chip 21 of this application can switch different numbers of terminals to form an electrical connection with the printing device 1, realize the rapid switching of user demand scenarios, and is simple to operate.

[0058] It is understood that in this embodiment, the number of the first communication terminal and the second communication terminal are different. The first communication terminal includes four communication terminals: the first terminal 21011, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015. The plane containing these four communication terminals can be understood as the first communication plane. The second communication terminal includes five communication terminals: the first terminal 21011, the third terminal 21013, the fourth terminal 21014, the fifth terminal 21015, and the second terminal 21012. The plane containing these five communication terminals can be understood as the second communication plane. The first and second communication planes are functionally descriptive planes, referring to the terminal data and communication stages / states included, rather than physical surfaces. Therefore, these two planes are not required to be physically flat. Multiple communication terminals can be uneven, as long as they functionally communicate with the printer at the same stage, they belong to the defined communication plane.

[0059] It should be noted that the chip select terminal is used to receive the chip select signal, which is a control signal used to select a specific consumable chip for communication. When multiple consumable chips are connected to the same communication bus, the chip select signal is used to indicate which consumable chip can exchange data with the printing device 1. For example, when the chip select signal is high, the consumable chip receives commands; when the chip select signal is low, the consumable chip stops receiving commands; or, conversely, when the chip select signal is low, the consumable chip receives commands; when the chip select signal is high, the consumable chip stops receiving commands.

[0060] It should be noted that, in some embodiments, the electronic module 21021 is used to ensure the effective management and storage of consumable cartridge information by the consumable chip 21, such as identification information and ink volume information. The electronic module can be implemented by integrated circuits, microcontrollers, etc., and further includes a control unit and a storage unit. The storage unit can use common non-volatile memory units, such as EPROM, EEPROM, FLASH, ferroelectric memory units, phase-change memory units, etc., or it can use a volatile memory unit plus a power supply, such as SRAM plus a battery or capacitor, DRAM plus a battery or capacitor, etc. The control unit is used to control the communication between the consumable chip and the printing device. The printing device reads information from the electronic module and stores information in the electronic module. The control unit can specifically be a microcontroller (MCU), microcontroller, FPGA, logic circuit (ASIC), etc. The composition of the electronic module can be selected according to actual needs, and is not limited here. The electronic module can be entirely embedded in a wafer, or it can be implemented by external circuit modules.

[0061] See Figures 8-9According to another embodiment of the first aspect of this application, the consumable chip 21 includes a first substrate 210 and a bending portion 211. The first substrate 210 includes a first plane 2101 and a second plane 2102 disposed opposite to each other. The first plane 2101 includes at least one first communication terminal. Preferably, the first communication terminal includes a first terminal 21011, a third terminal 21013, a fourth terminal 21014, and a fifth terminal 21015. Preferably, the second plane 2102 includes an electronic module 21021. The first terminal 21011, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 are electrically connected to the electronic module 21021 through wires or vias. The bending portion 211 includes a first structure 2111 and a second structure 2112. The first structure 2111 is disposed on the first substrate 210, and the second structure 2112 includes a second terminal 21012. Specifically, the second terminal 21012 is a chip select terminal, which is electrically connected to the electronic module 21021 through a wire and / or via on the bending portion. Preferably, the first structure 2111 is in contact with the first plane 2101, and the second structure 2112 is not in contact with the chip select pin of the printing device 1 in the first state, but is in contact with the chip select pin of the printing device 1 in the second state. Specifically, in the first state of the second structure 2112, the second terminal 21012 on the second structure 2112 does not contact the stylus of the printing device 1; in the second state, the projection of the second structure 2112 overlaps with the projection of the first substrate 210 (in the direction perpendicular to the first substrate 210), and the second terminal 21012 can contact the stylus of the printing device 1. The first state changes to the second state, that is, the second structure 2112 bends and flips in the direction of the first plane 2101, so that the second terminal 21012 can contact the chip select stylus of the printing device 1.

[0062] It is understood that, unlike the previous embodiment where the first structure 2111 of the bending portion 211 is disposed on the back side of the first substrate 210, in this embodiment the first structure 2111 of the bending portion 211 is disposed on the front side of the first substrate 210. When the printing device 1 is upgraded, the bending portion 211 is flipped over, so that the second structure 2112 is flipped on the same side of the front side of the first substrate 210, so that the second terminal 21012 (chip select terminal) and the first communication terminals (first terminal 21011, third terminal 21013, fourth terminal 21014 and fifth terminal 21015) on the first substrate 210 can communicate with the printing device 1 at the same time, so as to cope with the upgrade of the printing device 1, realize the rapid switching of user demand scenarios, and the operation is simple.

[0063] It should be noted that in some embodiments, the second terminal 21012 is preferably a chip select terminal to address the scenario where the prior art lacks a chip select terminal and is not resistant to upgrades. In some scenarios, the consumable chip may also lack other terminals to communicate with the printing device. Therefore, in other embodiments, the second terminal 21012 may also include other terminals, such as one or more combinations of data terminals, power terminals, clock terminals, ground terminals, or other terminals used for printing communication. By providing a bending portion 211 on the first substrate 210, and further by providing the second terminal 21012 on the bending portion 211, the problem of the consumable chip failing to communicate with the printing device due to the lack of other terminals can be solved.

[0064] See Figures 6-9 The first structure 2111 and the second structure 2112 are flexibly connected. Preferably, they are connected by a flexible circuit board (soft board), such as an FPC (Flexible Printed Circuit), which can be bent and folded.

[0065] Understandably, through flexible connection, the first structure 2111 and the second structure 2112 are more flexible, the second structure 2112 has more angles of movement than the first structure 2111, and the flexible circuit board is relatively thin, which makes it more adaptable in the assembly process with the printing device 1.

[0066] See Figure 10 According to the first aspect of the present application, the consumable chip 21 includes a bending portion 211, a first structure 2111 and a second structure 2112, and a second terminal 21012 is provided on the second structure 2112. Unlike the above embodiments, in this embodiment, the first structure 2111 and the second structure 2112 are hinged together. The first structure 2111 is disposed on the first plane 2101 or the second plane 2102 of the first substrate 210. The second structure 2112 can be flipped relative to the first structure 2111 to the first plane 2101 side or the second plane 2102 side of the first substrate 210 according to the application scenario.

[0067] It is understood that the first structure 2111 and the second structure 2112 are hinged together and can move relative to each other. When the printing device 1 is in the un-upgraded state (corresponding to the first state of the bent part), the second structure 2112 can be flipped to the back side (second plane 2102) of the first substrate 210 through the hinge axis, so that the second terminal 21012 does not contact the stylus of the printing device 1. In the second state, the second structure 2112 can be flipped to the front side (first plane 2101) of the first substrate 210 through the hinge axis and contact the adapter stylus of the printing device 1. Preferably, the second terminal is a chip select terminal, which contacts the chip select stylus of the printing device 1 in the second state. The first structure 2111 and the second structure 2112 connected by hinge have better positional stability after flipping and can better cooperate with the first substrate 210, making the printing process more stable.

[0068] See Figures 6-10 The bent portion 211 is disposed on the first substrate 210 by magnetic attraction or adhesive. In some embodiments, for the convenience of end users, the consumable chip 21 can be fixedly disposed on the first substrate 210 at the factory, for example by adhesive or welding. When the printing device is not upgraded, it communicates with the printing device 1 through the first communication terminal on the first substrate 210, which can solve many hidden dangers caused by using the chip select signal (RST) to control the read and write operations. After the printing device 1 is upgraded, the bent portion is flipped, and it communicates with the printing device 1 simultaneously through the second terminal on the bent portion and the first communication terminal on the first substrate (which constitute the second communication terminal) to cope with the upgrade of the printing device 1 and realize rapid switching. In other embodiments, the bending portion 211 and the first substrate 210 can also be manufactured separately. The bending portion 211 is detachably disposed on the first substrate 210, for example, by magnetic attraction or snap-fit. When the printing device is not upgraded, it communicates with the printing device 1 only through the first communication terminal on the first substrate 210. After the printing device 1 is upgraded, the bending portion 211 is disposed on the first substrate 210 and the bending portion is flipped. It communicates with the printing device 1 simultaneously through the second terminal on the bending portion and the first communication terminal on the first substrate to cope with the upgrade of the printing device 1. By using a detachable method, the bending portion is only used when the printing device is upgraded, which can reduce costs.

[0076] See Figures 15-16In another embodiment of this application, a consumable chip 21 is provided, including a first substrate 210 and a rotating shaft 2100. The rotating shaft 2100 is used to rotate the first substrate 210 left and right (X direction) about the rotating shaft 2100 as the center. Preferably, the rotating shaft 2100 can be fixed to the front surface 202 of the consumable box. The first substrate 210 includes a first plane 2101 and a second plane 2102 disposed opposite to each other. The first plane 2101 includes at least one communication terminal. Preferably, the communication terminal includes a first terminal 21011, a third terminal 21013, a fourth terminal 21014, a fifth terminal 21015 (the first terminal 21011, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 constitute the first communication terminal, and the plane where the first communication terminal is located constitutes the first communication plane), a first flip terminal 21011', and a second terminal 21012.

The electronic module 21021 is disposed on the first substrate 210, preferably on the second plane 2102.

[0077] Understandably, when the printing equipment is not upgraded, after the consumable cartridge is installed in printing equipment 1, the first terminal 21011, the third terminal 21013, the fourth terminal 21014, and the fifth terminal 21015 constitute the first communication terminal, which respectively contacts the first contact pin 1101, the third contact pin 1103, the fourth contact pin 1104, and the fifth contact pin 1105, as follows: Figure 15 As shown, at this time, the consumable chip 21 is in the first state, and the chip select pin of the printing device 1 is not in contact with the terminal on the first plane 2101; when the printing device 1 is upgraded, the consumable chip 21 of the consumable box is rotated, and the first flip terminal 21011', the second terminal 21012, the third flip terminal 21013', the fourth flip terminal 21014', and the fifth flip terminal 21015' constitute the second communication terminal, which respectively contacts the first contact pin 1101, the second contact pin 1102, the third contact pin 1103, the fourth contact pin 1104, and the fifth contact pin 1105, as shown.

[0078] Compared to the previous embodiment, which added terminals in the direction of gravity, i.e. the Y-axis direction, of the consumable chip 21, this embodiment differs in that it adds terminals in the horizontal direction, i.e. the X-axis direction. The first communication plane and the second communication plane share the first plane 2101 of the substrate 210, which can make full use of space. Therefore, the area of ​​the first substrate 210 in this embodiment is smaller and saves more materials.

[0079] It should be noted that in some of the above embodiments, the second terminal 21012 is preferably a chip select terminal to address the scenario where the prior art lacks a chip select terminal and is not resistant to upgrades. In some scenarios, the consumable chip may also lack other terminals to communicate with the printing device. Therefore, in other embodiments, the second terminal 21012 may also include other terminals, such as one or more combinations of data terminals, power terminals, clock terminals, ground terminals, or other terminals used for printing communication. By adding terminals on the first substrate 210 and flipping them or rotating them on the same side, the problem of the consumable chip failing to communicate with the printing device due to the lack of other terminals can be solved.

[0080] The consumable box provided according to the second aspect of the present application includes the consumable chip as described in the first aspect of the present application, and the consumable box has all the beneficial effects of the consumable chip.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this application should be included within the scope of protection of this application. Those skilled in the art will understand that the various functional units or modules in this application can be partially implemented by computer programs or by related hardware circuits, and there is no limitation thereto.
