Description

[0002] With the continuous development of imaging technology, image forming devices such as copiers, printers, fax machines, word processors, etc. have been widely used. These image forming devices all need to use consumables to perform image forming work, and print images or texts on imaging media (such as paper, etc.). When the consumables are used up, only by replacing or adding new consumables can they continue to be used.

[0003] Generally, after replacing the consumables, the image forming device needs to communicate with the consumables, including on-machine verification, monitoring of consumable remaining amount data, etc. For example, when installing a consumable into the image forming device, the image forming device will read the corresponding information, and then start the verification process to verify it. When the verification is successful, the consumable can be used for imaging, otherwise it is not allowed to use the consumable for imaging; for another example, during the printing process, the printer will interact with the consumable chip in real time to print information, and calculate the consumable remaining amount based on data such as printing duration or number of printed pages, and timely remind the user to replace the consumable.

Detailed implementation manners

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] In the description of the present application, unless otherwise clearly specified and limited, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; unless otherwise specified or stated, the term "plurality" means two or more, and the term "multiple types" means two or more types; the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0048] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0049] The consumable chip is a storage device, a memory device and a device for recording consumption. Before there was no consumable chip, it was usually necessary to visually check the ink end, and the "ink end" signal was not reported in advance. Therefore, it might cause the consumables to be exhausted halfway through printing and real-time information to be lost. The consumable chip can be used to prevent the print head from running without ink or toner and protect the print head.

[0050] However, for different models of printers, their consumable chips are often different, which hinders the use of consumables due to the non-universality of the consumable chips and increases the production cost of printing consumables.

[0051] Refer to Figure 1 and Figure 2As shown, the prior art discloses a stylus holder and a corresponding consumable chip. The stylus holder 200 includes a stylus base 201 and nine probes 202. The nine probes 202 are respectively installed on the stylus base 201, and the bottom of each probe 202 protrudes to form a terminal interface. The consumable chip 100' includes a substrate and nine conductive terminals 101'. The nine conductive terminals 101' are respectively arranged on the substrate, and each conductive terminal 101' is correspondingly arranged with each probe 202. During printing, each probe 202 contacts the corresponding conductive terminal 101' respectively to realize the communication connection between the image forming device side and the consumable chip. Hereinafter, the image forming device is taken as a printer for description.

[0052] With the upgrading of printed products, the communication method will change. For example, the upgraded new-generation printer does not need to use nine communication links for data exchange. After upgrading, only five communication links are required for communication. As Figure 3 and Figure 4 shown, the consumable chip 100' only needs to be provided with five conductive terminals 101', and only five probes 202 need to be reserved on the printer side, but the positions of the probes are not changed. That is to say, four probes are removed on the basis of the original nine probes, and the remaining five probes 202 are used for communication with the new type of consumables.

[0053] Referring to Figure 5 shown, an embodiment of the present application discloses a consumable chip 100. The consumable chip 100 includes a substrate 1, a second conductive terminal 3, a contact portion 4, a conductive wire 5, and a plurality of first conductive terminals 2. The plurality of first conductive terminals 2, the second conductive terminal 3, the contact portion 4, and the conductive wire 5 are respectively arranged on the substrate 1. The plurality of first conductive terminals 2 and the second conductive terminal 3 are used to contact the probes 202 on the printer side to realize the communication connection between the consumable chip 100 and the printer side. The contact portion 4 is located above any one of the first conductive terminals 2, and the contact portion 4 is equivalent to a functional terminal. One end of the conductive wire 5 is connected to the contact portion 4, and the other end of the conductive wire 5 is connected to the second conductive terminal 3.

[0054] When the consumable chip 100 is installed in the printer, the contact portion 4 and the first conductive terminal 2 located below the contact portion 4 can contact the same probe 202 (the probe is a strip-shaped conductive structure, forming a protruding terminal interface a at the bottom and a terminal interface b at the position corresponding to the contact portion 4. Refer to Figure 6 shown), so as to realize the communication connection between the printer and the consumable chip, and provide communication data for the printer through the contact portion 4, so that the consumable can be verified and passed by the printer.

[0055] In some embodiments, there are five first conductive terminals 2, and the five first conductive terminals 2 are used for matching communication with the upgraded printer. There are four second conductive terminals 3, and the four second conductive terminals 3 and the five first conductive terminals 2 are jointly used for matching communication with the printer before the upgrade. It can be understood that in other embodiments, there may also be five first conductive terminals 2 and one second conductive terminal 3.

[0056] In some embodiments, there is a fracture zone between the contact portion 4 and the conductive wire 5. The fracture zone can be a fracture crease 6 or a detachable conductor (not shown in the figure). When the consumable chip 100 is installed in the printer before the upgrade, the five first conductive terminals 2 and the four second conductive terminals 3 of the consumable chip 100 are respectively in contact with the nine probes 202 of the probe holder 200. At this time, the contact portion 4 does not need to be in contact with the probes 202. Therefore, the fracture crease 6 can be disconnected (for example, the contact portion can be broken off or the conductive wire can be manually cut) and the conductive wire can be isolated (an insulating film is covered on the conductive wire or the conductive wire is arranged inside the chip, or the contact portion 4 and the conductive wire are blocked (an insulating film is covered on the contact portion and the conductive wire)) to insulate the contact portion 4 and the conductive wire 5 and prevent it from affecting the contact between other conductive terminals and the probes.

[0057] It should be noted that in some other embodiments, the conductive wire 5 can also be replaced by other forms of conductors such as conductive sheets or conductive adhesives that can form a conduction path.

[0058] When the consumable chip is installed in the upgraded printer, the five first conductive terminals 2 and the contact portion 4 of the consumable chip are respectively in contact with the probes 202 of the probe holder 200. Since the number of printer probes is reduced, there are no probes at the positions corresponding to the second conductive terminals 3 on the consumable chip 100 on the probe holder 200, and no communication link will be formed, which will not affect the use of the new generation product, and the contact portion 4 is retained for implementing sub-functions.

[0059] Since the consumable chip 100 needs to be applicable to printers before and after the upgrade, two sets of data need to be stored in the consumable chip 100. The two sets of data can be set in the same memory or wafer, or can be separately provided with memory or wafer structures. During the replacement process between the old and the new, they are connected to the corresponding conductive terminals through a switch or a selection circuit.

[0060] In some embodiments, the consumable chip 100 further includes a storage circuit and a third switch. The storage circuit is disposed on the substrate 1, and the storage circuit stores first data and second data. The first conductive terminal 2 is used to interact with the printer for the first data, and the first conductive terminal 2 and the second conductive terminal 3 are used to interact with the printer for the second data. The third switch is disposed in the storage circuit and is used to control the connection or disconnection between the storage circuit and the first conductive terminal 2 and the second conductive terminal 3. Wherein, the storage circuit may include a memory and a wafer.

[0061] For example, when the consumable chip 100 is installed in a printer before upgrade, each first conductive terminal 2 and each second conductive terminal 3 are respectively in contact with the probe 202, and the third switch controls the storage circuit to be connected to the first conductive terminal 2 and the second conductive terminal 3, so that the consumable chip 100 can interact with the printer for the second data. When the consumable chip is installed in an upgraded printer, each first conductive terminal 2 is respectively in contact with the probe 202, and the third switch controls the storage circuit to be connected to the first conductive terminal 2, so that the consumable chip 100 can interact with the printer for the first data.

[0062] Specifically, the first conductive terminal 2 includes a voltage terminal VCC, a reset terminal RST, a clock terminal CLK, a data terminal SDA, and a ground terminal GND. Among them, the voltage terminal VCC is used to receive the power supply voltage of the printer, the reset terminal RST is used to receive the reset signal of the printer, the clock terminal CLK is used to receive the clock signal of the printer, and the data terminal SDA is used to receive or send a data signal to the printer.

[0063] In some embodiments, when the printer performs a verification operation on the consumable chip 100, the data output by the consumable chip 100 may not be provided by the inside of the consumable chip 100, but is obtained by the functional terminal (contact portion 4) receiving the signal sent by the printer to the consumable chip 100 and converting it.

[0064] Refer to Figure 7 and Figure 8As shown, the consumable chip 100 further includes a data conversion circuit 7. The contact portion 4 is located above the clock terminal CLK, such that the contact portion 4 and the clock terminal CLK correspond to the same probe 202. At this time, the contact portion 4 is equivalent to a clock terminal CLK'. The data conversion circuit 7 can be disposed at any position on the electrical connection path between the contact portion 4 and the data terminal SDA, that is, the data conversion circuit 7 is electrically connected to the data terminal SDA and the contact portion 4 respectively. In a preferred embodiment, the data conversion circuit 7 is electrically connected to the data terminal SDA and the second conductive terminal 3 electrically connected to the contact portion 4 respectively. Of course, in some embodiments, the data conversion circuit 7 can also be electrically connected to the contact portion 4 and the second conductive terminal 3 respectively. For example, a break can be provided on the conductive wire 5, and then the data conversion circuit 7 is connected to the break of the conductive wire 5, such that the signal received by the contact portion 4 can be transmitted to the second conductive terminal 3 through the conductive wire 5 and the data conversion circuit 7. When the consumable chip 100 is installed in a printer, the clock terminal CLK and the contact portion 4 are respectively in contact with the same probe 202. At this time, if the consumable chip 100 needs to transmit data back to the printer, the clock signal sent by the printer itself is data-converted by the data conversion circuit 7, and the data expected to be read by the printer is output through the data terminal SDA.

[0065] Referring to Figure 9 As shown, the data conversion circuit 7 includes an inverter 71 and a first switching element 72 connected in series. Specifically, the input end of the inverter 71 is electrically connected to the contact portion 4, and the output end of the inverter 71 is electrically connected to the data terminal SDA through the first switching element 72 to control the connection or disconnection of the data conversion circuit 7 through the first switching element 72. In a feasible embodiment, the inverter 71 can be disposed on the path between the contact portion 4 and the second conductive terminal 3, and the first switching element 72 is disposed on the path between the second conductive terminal 3 and the data terminal SDA. In another feasible embodiment, both the inverter 71 and the first switching element 72 are disposed on the path between the second conductive terminal 3 and the data terminal SDA. Of course, in other embodiments, the first switching element 72 can also be disposed at the input end of the inverter 71.

[0066] Illustratively, referring to Figure 10 As shown, in Figure 10Among them, D1 to D9 refer to the periods of the clock signal SCK. Assume that at time t1, the printer requires the data terminal SDA to output a low level, but the clock signal sent by the printer received by the clock terminal CLK is in a high level state. Then, the first switching element 72 is closed. At this time, the high level signal output by the contact part 4 is inverted by the inverter 71 to become a low level signal and is output to the printer through the data terminal SDA, enabling the printer to read the low level signal and meeting the verification requirements. Similarly, assume that at time t2, the printer requires the data terminal SDA to output a high level, but the clock signal sent by the printer clock line SCL received by the contact part 4 is in a low level state. Then, the first switching element 72 is closed. At this time, the low level data sent by the printer clock line SCL received by the contact part 4 is inverted by the inverter 71 to become a high level signal and is output to the printer through the data terminal SDA, enabling the printer to read the high level signal and meeting the verification requirements. At other times (such as t3), it is the same as at times t1 and t2. After the verification step is completed, the first switching element 72 is disconnected, and the data terminal SDA outputs other data to the printer to implement the printing function.

[0067] Referring to Figure 11 As shown, in order to facilitate the contact between the contact part 4 and the probe 202, the contact part 4 protrudes from the surface of each first conductive terminal 2. The contact between the first conductive terminal 2, the second conductive terminal 3 and the printer probe 202 is formed through the protruding terminal interface at the bottom of the probe. However, there is no protruding interface at the probe position corresponding to the contact part 4. Therefore, the contact part 4 needs to be set to have a certain thickness to facilitate the formation of a stable electrical connection with the probe. Preferably, the contact part 4 is set as a sharp corner structure protruding outward to facilitate positioning and installation.

[0068] In some embodiments, the data conversion circuit 7 may also include two parallel conversion lines. Specifically, the data conversion circuit 7 includes an inverter 71, a first switching element 72, and a second switching element 73. The input terminal of the inverter 71 is electrically connected to the contact portion 4, and the output terminal of the inverter 71 is electrically connected to the data terminal SDA through the first switching element 72. One end of the second switching element 73 is electrically connected to the contact portion 4, and the other end of the second switching element 73 is electrically connected to the data terminal SDA. In a feasible embodiment, the inverter 71, the first switching element 72, and the second switching element 73 are all arranged on the path between the second conductive terminal 3 and the data terminal SDA. In another feasible embodiment, the inverter 71, the first switching element 72, and the second switching element 73 are all arranged on the path between the contact portion 4 and the second conductive terminal 3. In yet another feasible embodiment, the inverter 71 is arranged on the path between the second conductive terminal 3 and the data terminal SDA, and the first switching element 72 is arranged on the path between the contact portion 4 and the second conductive terminal 3. Or, the inverter 71 is arranged on the path between the contact portion 4 and the second conductive terminal 3, and the first switching element 72 is arranged on the path between the second conductive terminal 3 and the data terminal SDA. Refer to Figure 12 shown. Assume that at time t1, the printer requires the data terminal SDA to output a low level, and the clock signal sent by the printer received by the contact portion 4 is in a high level state. Then, the first switching element 72 is closed, and the second switching element 73 is opened. The high-level data output by the contact portion 4 is inverted by the inverter 71 of the first conversion line into a low-level signal and output to the printer through the data terminal SDA, so that the printer reads the low-level signal, meeting the verification requirements. Assume that at this time the printer requires the data terminal SDA to output a high level. To meet the verification requirements, the first switching element 72 is opened, and the second switching element 73 is closed, so that the high-level signal received by the contact portion 4 is output to the printer through the data terminal SDA to complete the verification.

[0069] In some other embodiments, the data conversion circuit 7 may also be composed of only the second switching element 73.

[0070] Based on the above embodiments, the present application also discloses another specific implementation manner. Refer to Figure 13 and Figure 14As shown, the difference between this embodiment and the above-mentioned embodiment is that in this embodiment, the contact portion 4 is located above the data terminal SDA, such that the contact portion 4 and the data terminal SDA correspond to the same probe. The contact portion 4 and the data terminal SDA can receive the same data signal. At this time, the contact portion 4 is equivalent to a data terminal SDA'. The consumable chip 100 further includes a backup memory 8. The backup memory 8 is disposed on the substrate 1 and is electrically connected to the contact portion 4. In a feasible embodiment, the backup memory 8 is electrically connected to the contact portion 4 and / or the data terminal SDA through the second conductive terminal 3. In another feasible embodiment, the backup memory 8 is directly electrically connected to the contact portion 4 and / or the data terminal SDA.

[0071] After the contact portion 4 receives data and transmits it to the backup memory 8, the backup memory 8 only functions as a slave. It periodically (or when the cover is opened or restarted) compares whether the data in the data memory and the backup memory 8 is consistent. When they are inconsistent, an update mechanism is set. For example, the imaging task value or the consumable usage detection value is obtained to judge the rationality of the data memory and the backup memory, so as to perform data correction or synchronization, and transmit the corrected data to the printing device through the data terminal SDA and / or the data terminal SDA'. In addition, the data terminal SDA' (contact portion 4) can also have the function of a backup port. When the data terminal SDA fails, communication between the consumable chip and the printer can be achieved through the backup data terminal SDA'.

[0072] Based on the above-mentioned embodiment, the present application also discloses another specific implementation manner. In this embodiment, contact portions are provided above both the clock terminal CLK and the data terminal SDA, and the contact portion 4 (clock terminal CLK') above the clock terminal CLK and the contact portion 4 (data terminal SDA') above the data terminal SDA are both electrically connected to the data terminal SDA. The circuit structures and specific connection manners of the data conversion circuit 7 and the backup memory 8 are the same as those disclosed in the above-mentioned embodiment, and will not be elaborated herein.

[0073] Based on the above-mentioned embodiment, the present application also discloses yet another specific implementation manner. Referring to Figure 15 As shown, the difference between this embodiment and the above-mentioned embodiment is that in this embodiment, multiple contact portions 4 are provided. Each contact portion 4 is respectively located above a first conductive terminal 2, and each contact portion 4 is respectively electrically connected to a second conductive terminal 3 through a conductive wire. In this embodiment, two contact portions 4 are provided. One of the contact portions 4 is located above the clock terminal CLK and is equivalent to a clock terminal CLK'. The other contact portion 4 is located above the data terminal SDA and is equivalent to a data terminal SDA'.

[0074] Referring to Figure 16As shown, the consumable chip 100 further includes a data conversion circuit 7 and a backup memory 8. The data conversion circuit 7 and the backup memory 8 are respectively disposed on the substrate 1. The data conversion circuit 7 is disposed on the path connected between the clock terminal CLK' and the data terminal SDA'. The backup memory 8 is electrically connected to the data terminal SDA'. The specific connection manners of the data conversion circuit 7 and the backup memory 8 are the same as those disclosed in the above embodiments, and will not be elaborated herein. That is, the data conversion circuit 7 is electrically connected between the two contact portions 4, and the contact portion 4 located above the data terminal SDA is electrically connected to the backup memory 8.

[0075] In this embodiment, the functions of the two contact portions 4 are the same as those in the above embodiments. The difference is that in the printer and consumable verification stage, not only the data is output to the printer through the data terminal SDA, but also the data (including verification data and printing data) can be output to the printer through the contact portion 4 located above the data terminal SDA. At the same time, the contact portion 4 located above the data terminal SDA also has the function of data backup. For example, when the data terminal SDA is in poor contact with the printer probe (elastic member fatigue) and no data is received, if the signal received by the contact portion 4 located above the data terminal SDA is normal, the backup link can be activated to interact with the printer, thereby preventing printing failures from affecting the printing work.

[0076] It can be understood that the multiple contact portions 4 can also be electrically connected to the same second conductive terminal 3 through the same or multiple conductive paths. During time-sharing operation, the data conversion circuit 7 and the backup memory 8 can be respectively electrically connected to the same second conductive terminal 3 through the same or different conductive paths at different times to implement their respective corresponding functions.

[0077] Correspondingly, the embodiments of the present application also disclose a consumable, which includes the consumable chip described in any of the above embodiments.

[0078] As described above, the above are only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
