A specific chip storing the corresponding communication protocol and chip data is installed in a corresponding imaging cartridge, and that imaging cartridge can only be used with a specific type of imaging device. Therefore, as the number of imaging cartridges and imaging devices continues to increase, imaging cartridge manufacturers must stock different types of chips to produce imaging cartridges that can be used with different types of imaging devices. Furthermore, within the imaging industry, the recycling and refurbishment of various types of replaceable imaging cartridges, such as toner cartridges, drum cartridges, and inkjet cartridges, is a growing market. Remanufactured or refurbished imaging cartridges must be equipped with a replacement imaging cartridge chip to function properly. However, due to the settings of the original imaging device, each type of imaging cartridge chip data can only be used with one type of imaging cartridge. Therefore, imaging cartridge refurbishers must stock different types of chips for use when refurbishing different types of imaging cartridges. Patent publication number CN102658724A provides a method and imaging cartridge chip matching method. By configuring specific initial identification information in the imaging cartridge chip as legitimate identification information, including an identification bit, consumables quantity, and / or cartridge parameters, an imaging device can normally match the imaging cartridge chip based on the legitimate identification information.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The present invention provides a universal imaging box chip, which is applied to the imaging box of imaging equipment in the printing imaging industry. The universal imaging box chip includes: a controller, a memory, an interface circuit and an index circuit. The controller is connected to the memory, the interface circuit and the index circuit; the memory includes multiple data areas, and the multiple data areas respectively store information data of different types of imaging devices; the index circuit includes an index end. When the universal imaging box chip is powered on, the controller determines whether the state of the index end is an initial state. If so, the controller indexes to a default data area. If not, the controller indexes to a data area corresponding to the state according to the state of the index end; the controller communicates the information data of the imaging device in the indexed data area with the imaging device through the interface circuit.

[0031] The present invention can realize that one imaging box chip is applicable to various types of imaging boxes, and manufacturers do not need to stock different types of chips, which can greatly reduce the production inventory pressure of manufacturers and optimize the production process.

[0032] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] The present invention provides a universal imaging box chip, which is applied to the imaging box of the imaging equipment in the printing imaging industry. In this embodiment, the chip is combined with Figure 1 、 Figure 2 and Figure 3 The universal imaging box chip includes: a controller 10, a memory 20, an interface circuit 30 and an index circuit 40; the controller 10 is connected to the memory 20, the interface circuit 30 and the index circuit 40; the memory 20 includes multiple data areas 201, and the multiple data areas 201 respectively store information data of different types of imaging devices. The information data of different types of imaging devices are the information data of each type of imaging device burned into each data area 201 by a burning device before the imaging box chip leaves the factory. The index circuit 40 includes an index terminal. When the universal imaging box chip is powered on, the controller 10 determines whether the state of the index terminal is the initial state. If not, the controller 10 indexes to the data area 201 corresponding to the state according to the state of the index terminal. If so, the controller 10 indexes to the default data area 201, and the controller 10 communicates the information data of the imaging device in the indexed data area 201 with the imaging device through the interface circuit 30.

[0034] Specifically, before the universal imaging box chip is installed into the imaging device, the user needs to determine the model type of the imaging device. The external setting circuit sets the index circuit 40 according to the model type of the imaging device. The index circuit 40 sets the state of the index end according to the changes in the external setting circuit and feeds back to the controller 10. That is, different types of imaging devices correspond to different index end states. The index end is a port for the universal imaging box chip to judge and select the data area. Each data area 201 stores the information data of the imaging device. Different data areas 201 store information data of different types of imaging devices. There is a set initial state on the index end. Before the universal imaging box chip is installed into the imaging device, the user needs to determine the model type of the imaging device. If the model of the imaging device is the default model, the state of the index end remains unchanged and is the initial state. If the model of the imaging device is not the default model, the initial state of the index end is changed in a specific way, so that the universal imaging box chip can perceive the difference from the initial state during operation.

[0035] After the universal imaging box chip is installed in the imaging device, the imaging device is turned on, and the imaging box chip is powered on, the controller 10 of the universal imaging box chip first determines whether the state of the index end is the initial state, that is, whether the index end has changed compared to the initial state. If the state of the index end has changed (that is, it is not the initial state), the controller 10 indexes to the corresponding data area 201 in the memory 20 by judging the state of the index end, and communicates with the imaging device through the interface circuit 30. If the state of the index end has not changed, the controller 10 will directly enter the default data area 201 of the memory 20 and communicate with the imaging device through the interface circuit 30.

[0036] Further, such as Figure 4 As shown, in this embodiment, if the controller 10 determines that the state of the index end is the initial state, the controller 10 detects through the interface circuit 30 whether a setting instruction is received. The setting instruction refers to a pre-set special instruction. If so, after receiving the instruction, the controller 10 enters the setting mode to work. Otherwise, the controller 10 indexes to the default data area 201 and communicates with the imaging device through the interface circuit 30.

[0037] Furthermore, in this embodiment, the state of the index end includes a level state, a frequency state and / or an order state, etc. Different states can be identified by simply changing the state of the index end, thereby achieving indexing of different data areas 201.

[0038] Furthermore, in this embodiment, if Figure 3 As shown, the index terminal includes at least one index line 401. The controller 10 indexes to the data area 201 corresponding to the state according to the state of the index line 401. The chip indexes to the corresponding data area through the change of the index terminal to obtain the corresponding imaging device information. There are many specific indexing methods, and the following are examples:

[0039] Method 1:

[0040] There are at least two index lines 401, and the index lines 401 have at least two states, which can be a level state, a frequency state and / or an order state, etc. The index lines 401 correspond one-to-one to the data areas 201. The controller 10 detects the state of each index line 401, determines which index line 401 is selected, and indexes to the data area 201 corresponding to the index line 401.

[0041] Combine Figure 3 and Figure 5The universal imaging cartridge chip in the dashed box is marked with 1, 2, 3, and 4, which are four index lines, preferably conductive wires, and the four wires correspond to data areas A, B, C, and D corresponding to the information data of four different types of imaging devices stored in the memory 20. Taking the level state as an example, the wire has two level states, high and low. The wire port is set to high in normal circumstances, and low in the case of disconnection.

[0042] Before using the universal imaging cartridge chip, the user needs to disconnect the wire corresponding to the product model according to the needs of the product model, and then the universal imaging cartridge chip detects which wire is disconnected to appear low level after being powered on, thereby determining which data area 201 is selected by the customer, and finally indexing to the corresponding data area to obtain data and responding to the command of the imaging device.

[0043] Method two:

[0044] The index line 401 has at least two states, which can be level state, switch state, frequency state, and / or order state, etc. The controller 10 indexes to the data area 201 corresponding to the code according to the code composed of the states of all index lines 401 detected.

[0045] In combination Figure 3 With Figure 6 The universal imaging cartridge chip in the dashed box is marked with 1, 2, 3, and 4, which are four conductive wires. Taking the switch state as an example, the wire has two switch states, on and off. The four wires are in binary form, on represents 0, and off represents 1. Then the controller 10 of the universal imaging cartridge chip will combine the binary code composed of the on-off states of the four wires to point to the corresponding printer model data area A, B, C, D, E, F, G, and H.

[0046] For example, if wire No. 1 is disconnected as 1, and wires No. 2, 3, and 4 are on as 0, the binary code composed is 0 0 0 1, and the result of converting binary data to decimal data is 1, and the final selected data area is B;

[0047] For example, if wire No. 3 is disconnected as 1, and wires No. 1, 2, and 4 are on as 0, the binary code composed is 0 1 0 0, and the result of converting binary data to decimal data is 4, and the final selected data area is E;

[0048] For example, if wires No. 1 and 2 are disconnected as 1, and wires No. 3 and 4 are on as 0, the binary code composed is 0 0 1 1, and the result of converting binary data to decimal data is 3, and the final selected data area is D; and so on. The advantage of this method is that more data areas can be indexed with fewer wires.

[0049] Furthermore, in this embodiment, combined with Figure 1 and Figure 2 The universal imaging box chip further includes a substrate 10, on which a controller 20, a memory 30, an interface circuit 40, and an index circuit 50 are arranged. The substrate 50 of the present invention can be a PCB board, a multi-purpose board, an inlay, or other electronic components and circuit carriers; the controller 10 can be a microcontroller or microprocessor, a digital signal processor, a custom integrated circuit, a programmable logic device, a programmable gate array, etc.; the memory 20 can be a memory such as FLASH, EEPROM, or FRAM inside the controller, such as Figure 1 As shown, it can also be a memory component such as FLASH, EEPROM or FRAM connected to the controller, such as Figure 2 As shown; the interface circuit 30 is a circuit sent from the imaging device to the chip and from the chip to the imaging device, and is provided with a contact interface or a contactless interface connected to the imaging device.

[0050] An embodiment of the present invention further provides an imaging box, comprising the universal imaging box chip in the above embodiment, wherein the universal imaging box chip is detachably mounted on the imaging box.

[0051] An embodiment of the present invention further provides an imaging device, comprising the imaging box in the above embodiment.

[0052] The universal imaging box chip, imaging box and imaging device in the above-mentioned embodiments can realize that one imaging box chip is applicable to multiple types of imaging boxes. The universal imaging box chip internally stores information data of multiple types of imaging devices. By judging the status of the index end set by the outside world, the corresponding type of imaging device data is selected to work. The manufacturers and refurbishment manufacturers of imaging boxes only need to use the universal imaging box chip interface of the present invention to be applicable to multiple imaging boxes. There is no need to stock different types of chips, which can greatly reduce the production inventory pressure of manufacturers and optimize the production process.
