Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information processing device, a control method, consumables and an image forming device. Background Art

[0002] Image forming apparatus is a computer peripheral device. With the maturity of imaging technology, it has gradually become popular in offices and homes due to its advantages of high speed and low single-page imaging cost. According to different functions, image forming apparatuses include printers, copiers, multi-function machines, etc. According to different imaging principles, image forming apparatuses include laser printers, inkjet printers, dot matrix printers, etc.

[0003] The image forming device performs printing control through the image forming control unit. Due to the use cost problem, the image forming control unit is usually a system on chip SoC (System on Chip, also known as system on chip), but the system on chip SoC sometimes has certain resource limitations. For example, since the system on chip SoC usually runs on the Linux system, and the Linux system is a non-real-time operating system, it usually allocates information processing time to each task fairly through time slice rotation and other methods. When some tasks are running under high load, other tasks will not be allocated processing time in time, resulting in processing delays for other tasks. For example, when the printing engine needs a printing engine control signal such as a paper pickup signal in real time, if it relies on the image forming control unit to output the printing engine control signal, the printing engine control signal time control will be inaccurate, and timing deviations are prone to occur, resulting in a decrease in printing quality. The usual way to solve this problem is to add a controller CPU to the image forming device to share the execution tasks of the system on chip SoC, but this also greatly increases the cost.

[0088] See also Figure 1 , is a schematic diagram of the structure of an image forming system provided in an embodiment of the present application. Figure 1 As shown, the image forming system includes an image forming apparatus 100 and consumables 200 .

The image forming control unit may be a system on chip (SoC), which is a micro system composed of components of multiple systems and is configured to control the imaging processing operations of the image forming device 100, such as linear correction, noise reduction, bad pixel removal, detail enhancement, etc. of the image data, so as to improve the quality of the image output. The image forming control unit is also used to perform processing operations related to data transmission and reception, command transmission and reception, and engine control of printing images, such as transmitting and receiving data, printing engine control commands, status, etc. through an interface unit (including but not limited to a USB port, a wired network port, a wireless network port, or other interfaces, etc.). Accordingly, the information processing device may be a consumable 200 that is detachably mounted on the image forming device, and the consumable 200 is generally an ink cartridge, a toner cartridge, a toner cartridge, a toner cartridge, a ribbon cartridge, etc. The consumable 200 may also be other easily damaged components, parts, units (such as paper boxes, etc.) that can be installed in the image forming device 100 and need to be replaced, which also belongs to the technical solution corresponding to the consumable protected by this application. In addition, the information processing device may also refer to a circuit unit installed on the consumable 100, which is composed of one or more hardware circuits. In some embodiments, at least part of the one or more hardware circuits includes a processor.

[0090] For the consumables 200 of the image forming system, one possible implementation is that the consumables 200 are of a split structure, including a drum box and a developer box that are detachable from each other, wherein the drum box includes a photosensitive drum and a charging roller, and the developer box includes a developer container, a developer roller, and a developer conveying element. Another possible implementation is that the consumables 200 are of an integrated structure, for example, the consumables 200 include a developer container, a developer roller, a developer conveying element, a photosensitive drum, a charging roller, etc.

[0091] Furthermore, the consumable 200 may also include only a shell and a developer containing portion. It is additionally noted that the consumable 200 may also be the aforementioned developer box or drum box. The aforementioned developer containing portion is used to contain a developer such as toner, and the developer conveying element is a component such as a powder feeding roller, a powder feeding screw, etc., for stirring and / or conveying toner. Of course, the aforementioned developer box may also include only the aforementioned developer containing portion, which is not limited here. Furthermore, the aforementioned developer box may also include only the aforementioned developer containing portion and the developer conveying element, which is not limited here.

[0092] In a possible implementation, the consumable 200 may also include a powder cartridge and / or an imaging component, and the powder cartridge is used to deliver toner to the imaging component when the toner contained in the imaging component is insufficient so that the image forming device forms an image based on the toner delivered by the imaging component, wherein when the consumable 200 is a powder cartridge, the consumable 200 may only include a housing and a developer containing portion, or may include a housing, a developer containing portion, and a developer conveying element, which is not limited in this application. When the consumable 200 is an imaging component, the consumable 200 may include a housing, a developer containing portion, a developer conveying unit, a charging roller, a photosensitive drum, etc., which is not limited in this embodiment of the application.

[0093] Usually, the consumable 200 is also used in conjunction with a consumable chip. In one embodiment, the consumable chip can be installed on the consumable 200. The consumable chip can be installed on the consumable 200 before the consumable 200 leaves the factory, or it can be installed on the consumable 200 by the user after the consumable 200 leaves the factory. In another embodiment, the consumable chip does not need to be installed on the consumable 200, but is fixed to the image forming device 100 by a mounting member or an adhesive. When the image forming device uses the consumable 200, the contact points of the consumable chip are in electrical contact with the contact terminals corresponding to the image forming device 100, thereby realizing the electrical connection between the consumable chip and the image forming device 100. When the image forming device does not use the consumable 200 (the consumable is not in working state), the contact points of the consumable chip may or may not be in contact with the contact terminals corresponding to the image forming device 100. For example, when the consumable 200 is installed in the image forming device but not used, or when the consumable is taken out of the image forming device. It should be noted that when the consumables 200 are of the aforementioned split structure including a drum box and a developer box that are detachable from each other, the drum box and the developer box are usually equipped with consumable chips respectively.

[0094] In some possible implementations, the information processing device is a consumable chip or a consumable chipset. When the consumable chip is electrically connected to the image forming device 100, the consumable chip can communicate with the image forming device 100, and can provide information related to the consumable 200 to the image forming device 100 through the consumable chip, so that the image forming device 100 can obtain basic information about the consumable 200, such as the manufacturer, the type, color, capacity and usage of the recording material (toner, ink), etc. In addition, during the image forming operation, the image forming device 100 can also write the update information of the consumable 200 (for example, the usage of the developer) into the consumable chip. In one embodiment, the consumable chip includes a substrate and a plurality of contact contacts, the plurality of contact contacts are arranged on the substrate, and each contact contact is respectively used to be electrically connected to a plurality of contact terminals arranged on the image forming device 100, thereby realizing the communication between the image forming device 100 and the consumable chip, wherein the plurality of contact contacts may include a power contact VCC, a ground contact GND, a data line contact SDA, and a clock line contact SCL. In another embodiment, the consumable chip in the embodiment of the present application may further include an adapter plate in addition to the substrate, wherein the adapter plate is electrically connected to the substrate, and at least part of the aforementioned plurality of contact points may be disposed on the adapter plate. Figure 2 , the second communication interface 211 of the consumable chip 210 can be electrically connected to the first communication interface 102 of the image forming device 100, thereby being electrically connected to the processor 101 of the image forming device 100 through the first communication interface 102. In one embodiment, the above-mentioned first communication interface 102 and the second communication interface 211 can be I2C interfaces respectively. The second power supply interface 212 of the consumable chip can be electrically connected to the first power supply interface 103 of the image forming device 100, so that the image forming device 100 can power the consumable chip through the first power supply interface 103 and the second power supply interface 212. In one embodiment, the information processing device is a consumable chipset including a first consumable chip and a second consumable chip. In some embodiments, see Figure 3 , the first consumable chip 210 (the first consumable chip is Figure 2The first consumable chip 210 is a consumable chip in the image forming device 100 and is communicatively connected with the second consumable chip 220. When the image forming device 100 communicates with the first consumable chip 210, the image forming device 100 acts as a host to send instructions to the first consumable chip 210, and the first consumable chip 210 acts as a slave to respond to the instructions sent by the host. When the first consumable chip 210 and the second consumable chip 220 communicate, the first consumable chip 210 acts as a host to send instructions to the second consumable chip 220, and the second consumable chip 220 acts as a slave to respond to the instructions sent by the first consumable chip 210. Among them, the instructions sent by the first consumable chip 210 to the second consumable chip 220 can be generated by the first consumable chip 210, or the first consumable chip 210 can forward the instructions sent by the image forming device 100. At this time, the first consumable chip 210 determines who should process the instructions sent by the image forming device 100, and when it is determined that the instructions should be processed by the second consumable chip 220, the instructions are forwarded to the second consumable chip 220. The third communication interface 213 of the first consumable chip 210 can be electrically connected to the fourth communication interface 221 of the second consumable chip 220. In one embodiment, the third communication interface 213 and the fourth communication interface 221 can be wired communication interfaces, preferably I2C interfaces, or optical, infrared or other appropriate information transmission path interfaces. In some embodiments, a switch controlled by the first consumable chip 210 is provided in the communication link between the first consumable chip 210, the second consumable chip 220 and the image forming device 100. When the first consumable chip 210 determines that the first consumable chip 210 needs to communicate with the image forming device 100 at the current stage, the communication link between the first consumable chip 210 and the image forming device 100 is connected through the switch, or the communication link between the first consumable chip 210 and the image forming device 100 is kept connected. When the first consumable chip 210 determines that the second consumable chip 220 needs to communicate with the image forming device 100 at the current stage, the communication link between the second consumable chip 220 and the image forming device 100 is connected through the switch. When the first consumable chip 210 determines that the second consumable chip 220 does not need to communicate with the image forming device 100 at the current stage, the communication link between the second consumable chip 220 and the image forming device 100 is disconnected through the switch.

[0095] In some possible implementations, the information processing device includes the aforementioned consumable chip or consumable chipset, and an auxiliary circuit module. The consumable chip is connected to the auxiliary circuit module, specifically through a wired communication interface, or through an optical, infrared or other appropriate information transmission path interface. The auxiliary circuit module is used to implement some functions of the consumable chip, or additional functions. The auxiliary circuit can respond to the indication of the consumable chip, or be enabled by a signal other than the instruction of the consumable chip, to provide the consumable chip or the main device with corresponding data information or waveform information and other information. The auxiliary circuit module may include logic units such as AND gates, OR gates, NOT gates, triggers, etc., and may also include circuit units of devices such as FPGA, MCU, DSP, etc. Those skilled in the art can design the auxiliary circuit module according to actual needs. The embodiment of the present application does not limit the composition and specific functions of the auxiliary circuit module.

[0096] like Figure 4 As shown, the image forming device 100 further includes a transfer roller 4, a paper box 20, a paper feed roller (paper pickup roller, paper pickup roller) 21, a conveying roller 22, a correction roller 23, a laser 30, a fixing unit 40, a discharge paper box 50, a conveying roller 51, a conveying roller 52 and a conveying roller 53, etc., and the processing box includes a photosensitive drum 1, a charging roller 2 and a developing roller 3, etc. The paper box 20 is used to store paper P, the paper feed roller 21 is used to convey the paper P to the conveying path; the conveying roller 22 is used to convey the paper P to the clamping area between the photosensitive drum 1 and the transfer roller 4, and discharge the imaged paper to the discharge paper box 50 after passing through the fixing unit 40, and the correction roller 23 is used to align and correct the edge of the paper feed to prevent the paper from tilting and affecting the image formation quality. The charging roller 2 is used to charge the surface of the photosensitive drum 1, the laser 30 emits a laser beam to form an electrostatic latent image on the surface of the photosensitive drum 1, and the developing roller 3 is used to develop a toner image on the surface of the photosensitive drum 1. When the paper P passes through the nip area between the photosensitive drum 1 and the transfer roller 4, the toner image formed on the surface of the photosensitive drum 1 is transferred to the paper by the transfer roller 4. The fixing unit 40 is used to fix the toner image on the paper P. The fixed paper P is conveyed by the conveying rollers 51-53, discharged from the discharge paper box 50 and stacked.

[0097] Combination Figure 4 The components to be controlled of the image forming device 100 include but are not limited to: motor ( Figure 4 Not shown), cleaning roller ( Figure 4 (not shown), charging roller 2, laser 30 (LSU), developing roller 3, transfer roller 4, fixing roller (fixing unit 40), paper feed roller (pick-up roller, paper pickup roller) 21, conveying roller 22, conveying rollers 51-53, correction roller 23, high-voltage plate ( Figure 4 Not shown), electromagnet ( Figure 4 Not shown) and relays ( Figure 4(not shown) and so on.

[0098] In actual applications, the system-on-chip (SoC) sometimes has the problem of limited resources. For example, since the system-on-chip (SoC) usually runs on the Linux system, affected by the operating mechanism of the system, the system CPU resources are often preempted, resulting in inaccurate time control of the print engine control signal output by the system-on-chip (SoC), which is prone to timing deviation and reduced printing quality. The usual way to solve this problem is to add a controller CPU to the image forming device to share the execution tasks of the system-on-chip (SoC), but this also greatly increases the cost.

[0099] In view of the above problems, the embodiments of the present application provide an information processing device, a control method, consumables and an image forming device. The present application outputs a control signal to control the component to be controlled by an information processing device used in conjunction with the consumables. Since the information processing device is based on a single-task system of a single-chip microcomputer, it can better and more accurately control the timing of signal output compared to the image forming control unit running on the Linux system, without any additional cost.

[0100] The following is a description with reference to the accompanying drawings.

Specifically, after the signal processing module 320 generates a control signal, it notifies the ready signal output module 340 to output a ready signal, or after the signal processing module 320 generates a control signal, it outputs the ready signal through the ready signal output module 340, that is, the signal processing module 320 can also generate a ready signal and output the ready signal through the ready signal output module 340.

[0102] In a possible implementation, the first port 350 may be a data line port (SDA port) in an I2C communication bus, and the second port 360 may be a clock line port (SCL port) in an I2C communication bus. Correspondingly, the first pin 110 may be a data line pin (SDA pin) of the image forming device 100, and the second pin 120 may be a clock line pin (SCL pin) of the image forming device 100. Of course, in practical applications, the first port 350 may also be an SCL port in an I2C communication bus, and the second port 360 may also be an SDA port in an I2C communication bus. Correspondingly, the first pin 110 is an SCL pin of the image forming device 100, and the second pin 120 is an SDA pin of the image forming device 100. Both circuit connection structures can implement the technical solutions of the embodiments of the present application, and users can select them according to their needs. The embodiments of the present application do not make specific requirements for this. The signal receiving module 310 usually receives the notification signal sent by the image forming device through the data line port (SDA port).

[0103] The implementation of the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 of the information processing device. In the embodiment of the present application, the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 can be implemented by software or by hardware.

[0104] Specifically, the aforementioned signal receiving module 310, signal processing module 320, control signal output module 330 and ready signal output module 340 can be circuit units including devices such as FPGA, MCU, DSP, etc. The control signal output module 330 and the ready signal output module 340 can realize their functions by building a specific waveform generator circuit, and the signal receiving module 310 and the signal processing module 320 can also realize corresponding functions by building a digital logic calculator. The present application does not further limit the specific implementation form of each unit.

[0105] When the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 are different circuit elements, the signal processing module 320 is electrically connected to the signal receiving module 310, the control signal output module 330 and the ready signal output module 340. Specifically, Figure 6 As shown, in Figure 5On the basis of, the input end of the signal processing module 320 is electrically connected to the output end of the signal receiving module 310, for receiving the notification signal output by the signal receiving module 310 and generating a control signal according to the notification signal; the input end of the control signal output module 330 is electrically connected to the output end of the signal processing module 320; the input end of the ready signal output module 340 is electrically connected to the output end of the signal processing module 320.

[0106] In one possible implementation, the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 are all included in the consumable chip. Preferably, the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 are all included in the chip control unit of the consumable chip, and the chip control unit can be implemented based on the MCU.

[0107] In a possible implementation, the signal receiving module 310, the signal processing module 320, the control signal output module 330 and the ready signal output module 340 are respectively included in the first consumable chip and the second consumable chip. Exemplarily, the signal receiving module 310, the control signal output module 330 and the ready signal output module 340 are included in the first consumable chip, the first consumable chip also includes the aforementioned first port 350 and second port 360, and the signal processing module 320 is included in the second consumable chip. After the signal receiving module of the first consumable chip receives the notification signal sent by the image forming device, it forwards the notification signal to the second consumable chip, the signal processing module of the second consumable chip generates a control signal according to the notification signal, and outputs the control signal to the first consumable chip, and outputs the control signal through the control signal output module 330 and the first port 350 of the first consumable chip, and the ready signal output module of the first consumable chip outputs the ready signal to the image forming device through the second port before the control signal output module outputs the control signal. In one possible implementation, since in the image forming device, it is mainly the image forming control unit that controls the image forming device as a whole, such as sending signals to an external device, or receiving signals sent by an external device, and performing corresponding control according to the signals, etc., the information processing device 300 of the embodiment of the present application can be communicatively connected with the image forming control unit of the image forming device 100, that is, the first pin 110 and the second pin 120 are respectively the data line pin SDA and the clock line pin SCL of the image forming control unit, or the first pin 110 and the second pin 120 are the clock line pin SCL and the data line pin SDA of the image forming control unit.

[0108] In the embodiment of the present application, the information processing device is an integrated circuit capable of performing calculation processing and logic processing. When the information processing device runs a real-time operating system or other system capable of executing tasks in a timely manner, the control signal output by the information processing device to the controlled component can better and more accurately control the output timing of the control signal compared to outputting the control signal through the image formation control unit.

[0109] In one possible implementation, the notification signal is an instruction of a data frame, which is used to inform the signal processing device 300 that a control signal needs to be output. The instruction includes description information of the control signal, such as the type, period, duty cycle, duration and number of occurrences of the control signal, etc. After receiving the notification signal, the signal processing module 320 generates a corresponding control signal according to the description information of the control signal in the notification signal.

[0110] In another possible implementation, the notification signal may be a preset waveform signal, such as a signal level of high-low-high-low-high. After receiving the notification signal, the signal processing module 320 parses the preset waveform signal according to a preset protocol to obtain description information of the control signal, and then generates a corresponding control signal according to the description information of the control signal.

[0111] In the embodiment of the present application, after the signal processing module 320 generates a control signal, the ready signal output module 340 sends a ready signal to the image forming device 100 through the second port 360, so as to inform the image forming device that the control signal output is ready and will be output to the first pin 110 through the first port 350, and the first switch S1 is controlled to be closed. After the image forming device 100 receives the ready signal, it closes the first switch S1 according to the ready signal.

[0112] In a possible implementation, the ready signal may be a continuous output signal, that is, the ready signal always exists during the control signal output period. After the image forming device 100 receives a continuous output signal through the second pin 120, it controls the first switch S1 to be closed, so that the information processing device 300 is connected to the component to be controlled 400 for communication. After the control signal output is completed, the ready signal output module 340 stops outputting the ready signal. After the image forming device 100 fails to receive the ready signal, it controls the first switch S1 to be opened.

[0113] For example, Figure 7As shown, the bus between the first port 350 and the first pin 110 includes a data line SDA, and the line between the second port 360 and the second pin is a clock line SCL. When the bus is an I2C bus, SDA and SCL are in a high level state in a natural state, that is, when the image forming device 100 and the information processing device 300 have no information output, SDA and SCL are high level, when the image forming device 100 and / or the information processing device 300 have information output on the corresponding line, SDA and / or SCL perform level conversion according to the corresponding output information, that is, when the binary number 1 is output, it is a high level state, and when the binary number 0 is output, it is a low level state. Of course, in actual applications, the level state can also be the opposite, that is, SDA and SCL are in a low level state in a natural state, and when there is information output, the corresponding level state conversion is performed, and the embodiment of the present application does not make specific limitations on this.

[0114] When the image forming device 100 requires the information processing device 300 to output a control signal to control the component to be controlled 400, the image forming device 100 powers on the information processing device through the power supply VCC. At this time, both SDA and SCL are in a high level state. Then the image forming device 100 sends a notification signal to the information processing device 300 through SDA, and sends a clock signal to the information processing device 300 through SCL. At this time, SDA and SCL perform level conversion based on the corresponding signals. Before the information processing device 300 prepares to output a control signal according to the notification signal, it obtains the control right of the SCL clock line and sends a ready signal to the image forming device 100 through SCL, that is, sends a continuous low level signal. After receiving the continuous low level signal, the image forming device 100 controls the first switch S 1 is closed to enable the information processing device 300 to communicate with the component to be controlled 400. Subsequently, the information processing device 300 obtains the control right of the SDA signal line and outputs the control signal through SDA. The control signal passes through the first switch S1 and is input into the component to be controlled 400. After the control signal is output, the information processing device 300 releases the control right of the SDA signal line, and the ready signal on SCL stops being output. The information processing device 300 releases the control right of the SCL clock line, and the image forming device disconnects the first switch S1, and SDA and SCL are in a high level state again. At this time, if the image forming device 100 needs the information processing device 300 to generate a control signal, the information processing device 300 is continuously powered on and the above steps are repeated. Otherwise, the power supply to the information processing device 300 can be turned off.

[0115] In another possible implementation, the ready signal is a signal of a specific waveform, such as a signal level of low-high-low. When the image forming device 100 receives the signal of the specific waveform through the second pin 120, the first switch S1 is controlled to be closed. In this case, after the control signal output is completed, the ready signal output module 340 also needs to send a completion signal to the image forming device 100 to instruct the image forming device 100 to control the first switch S1 to be disconnected, wherein the completion signal can be a signal of another specific waveform.

[0116] For example, Figure 8 As shown, Figure 7 The difference is, Figure 8 The ready signal is a signal with a specific waveform. After the information processing device 300 outputs the ready signal, there is no more signal output on SCL, that is, SCL is in a high level state until the control signal is output. The information processing device 300 outputs a completion signal through SCL, and the level state on SCL is changed accordingly according to the completion signal. After the image forming device 100 receives the completion signal, the first switch S1 is disconnected, and SDA and SCL are in a high level state again. At this time, if the image forming device 100 needs the information processing device 300 to generate a control signal, the information processing device 300 is continuously powered, and the above steps are repeated. Otherwise, the power supply to the information processing device 300 is turned off.

[0117] In the embodiment of the present application, before the information processing device sends a control signal, the closure of the switch S1 is controlled by a ready signal to enable the information processing device to communicate with the component to be controlled, thereby outputting the control information sent by the information processing device to the component to be controlled. The overall control logic is simple and easy to implement, and no additional electrical components are required except the switch, so the circuit control cost is low.

[0118] In a possible implementation, in order to ensure accurate control of the control timing, the signal processing device 300 is further provided with a timing module 370, such as Fig. 9 As shown, the timing module 370 is in communication connection with the signal processing module 320. In a specific implementation, the timing module 370 is used to start timing when the ready signal output module 340 outputs the ready signal, and notify the control signal output module 330 to output the control signal through the signal processing module 320 when the preset duration is reached. Among them, the preset duration can be set according to the needs, and the embodiment of the present application does not make specific requirements for this. For example, the preset duration is set to 100ms, that is, the control signal is output 100ms after the ready signal starts to be output.

[0119] It should be noted that the timing module can be Fig. 9It can be set separately as shown in , or it can be set in the signal processing module 320 or the ready signal output module 340, and the embodiment of the present application does not make specific requirements for this.

[0120] The embodiment of the present application uses an information processing device used in conjunction with consumables to output control signals, and achieves precise timing control of the components to be controlled without additional cost, thereby improving the printing performance of the image forming device. Moreover, the information processing device and the components to be controlled are connected by communication only through a switch, without additional line settings, and the overall structure is simple and easy to implement.

[0121] The following description will take the communication connection between the information processing device and the image formation control unit as an example.

[0122] See also Fig.10 , is a schematic diagram of a circuit connection structure of an information processing device and an image forming control unit provided in an embodiment of the present application. Among them, the aforementioned signal receiving module, signal processing module, control signal output module, ready signal output module and timing module of the information processing device are respectively included in the chip control unit MCU, the VCC port of the information processing device and the VCC pin of the image forming control unit are electrically connected to the external power supply VCC, the SDA port of the information processing device is electrically connected to the SDA pin of the image forming control unit, and is electrically connected to the power supply VCC through a resistor R1, the SDA pin of the image forming control unit is electrically connected to one end of the first switch S1, and the other end of the first switch S1 outputs a control signal, the SCL port of the information processing device is electrically connected to the SCL pin of the image forming control unit, and is electrically connected to the power supply VCC through a resistor R2, and the GND port of the information processing device is electrically connected to the GND pin of the image forming control unit.

[0123] Specifically, when the image forming control unit needs the information processing device to output a control signal, the agreed protocol notification is sent to the information processing device through the SDA signal line. The agreed protocol notification can be a data frame instruction containing the description information of the control signal, or a set waveform signal. After receiving the agreed protocol notification, the information processing device parses the agreed protocol notification to generate a control signal and enters a ready state where the control signal can be output. At this time, the information processing device obtains the control right of the SCL signal line and sets the SCL signal line low to inform the image forming control unit that the signal output is ready, and the control right of the SDA signal line is to be obtained and the control signal is output on the SDA signal line. After the image forming control unit detects the low level continuously output on the SCL signal line, it immediately closes S1, so that the information processing device is connected to a specific engine component through SDA. The information processing device starts timing from the beginning of outputting a low level on the SCL signal line, and outputs a control signal on the SDA signal line after reaching a preset time, for example, after 100ms. After the information processing device has finished outputting the control signal, it first releases SDA and then releases SCL (i.e. stops outputting a low level). After the release, both SDA and SCL are at a high level and are in a communicative state. At this time, if the image forming device needs the information processing device to continue to generate control signals, the above steps can be repeated.

[0124] In a specific implementation, the specific component to be controlled may be a paper picking mechanism, that is, the control signal is used to control the paper picking mechanism to pick up paper, such as Fig.11 As shown, the control signal output by the information processing device first reaches the driving circuit 410, and the driving circuit 410 obtains the driving signal after amplifying the signal power. Fig.12 After the driving signal is input to the paper pickup mechanism 500, the fixed hook on the paper pickup roller 21 is controlled to release the paper pickup roller 21, thereby performing the paper pickup operation.
