The present invention relates to an information processing device and a program.

2. Description of the Related Art Conventionally, an information processing apparatus has been known that can operate in a normal mode for normal operation and a test mode for testing, and can transmit test results to a management server (for example, Patent Document 1).
In the above-described information processing apparatus, when an error occurs while operating in the normal mode, log information necessary for diagnosing the cause of the error is stored in the storage unit. After storing the log information, the information processing device shifts to a test mode and performs diagnosis based on the log information stored in the storage unit.

Some information processing devices shift from a normal mode to an energy saving mode (hereinafter referred to as energy saving mode) that suppresses power consumption. This information processing device can store various types of information in the storage unit in the normal mode, but cannot store various types of information in the storage unit in the energy saving mode because power supply to the storage unit is stopped.
Therefore, in this information processing device, various information cannot be stored in the storage unit at irregular timings from the start of the transition from the normal mode to the energy saving mode to the end of the transition.

When the information processing device of Document 1 is configured to be able to shift to the energy saving mode, there may be a problem that log information cannot be stored in the storage unit during the transition from the normal mode to the energy saving mode.
The present invention has been made in view of the above circumstances, and aims to suppress the inconvenience that log information cannot be stored in the storage unit at the time of mode transition.

The main invention for solving the above-mentioned problems includes an operating unit that performs various operations, determining the occurrence of an abnormality during the operation of the operating unit, and acquiring log information used for diagnosis to determine the content of the abnormality. a control unit that causes the log information to be stored in the storage unit, and transitions between a first mode in which the log information can be stored in the storage unit and a second mode in which the log information cannot be stored in the storage unit. In the information processing device, the control unit starts the transition to the second mode when a mode transition condition is satisfied in the first mode, and starts the transition to the second mode from the satisfaction of the mode transition condition. If it is determined that the abnormality has occurred within the transition period before migration, the abnormality is a first abnormality that requires the log information to be stored in the storage unit and a need to store the log information in the storage unit. If it is determined that the abnormality is the first abnormality, then the transition to the second mode is stopped until the log information related to the first abnormality is stored in the storage unit. Characterized by delay.

According to the present invention, the inconvenience that log information cannot be stored in the storage unit at the time of mode transition is suppressed.

For example, when the power button SW is operated in the normal mode (first mode) in which power is supplied to the MFP 100 (when the mode transition conditions are met), the power button SW is operated in the energy saving mode (first mode) in which power consumption is suppressed compared to the normal mode. 2 mode) and a power-off state (second mode) in which the supply of power to the MFP 100 is stopped.
The HD 108 included in the MFP 100 of the first embodiment can write and read information in the normal mode, but cannot write or read information in the energy saving mode or power-off state.

In the MFP 100 of this embodiment, when the power button SW is pressed for a predetermined time or longer, the MFP 100 transitions to the power off state, and when the power button SW is pressed for less than the predetermined time, the MFP 100 transitions to the energy saving mode.
Furthermore, in the normal mode, if no operation is performed on the operation panel 140 or the like for a specified period of time, the MFP 100 shifts to the energy saving mode.
In the MFP 100, when the power button SW is operated in the power off state, the MFP 100 shifts to the normal mode. Similarly, in the MFP 100, when the operation panel 140 is operated in the energy saving mode or the power button SW is operated, the MFP 100 shifts to the normal mode.

The CPU 101 and the like diagnose the presence or absence of an abnormality in the printer unit 4 and the like and the details of the abnormality based on the log information stored in the HD 108 . Furthermore, if an abnormality is detected during the period of transition from normal mode (first mode) to energy saving mode (second mode), MFP 100 will not transition to energy saving mode until log information related to the abnormality is stored in HD 108. It's delayed.
By employing the above configuration, in the MFP 100 of this embodiment, log information related to an abnormality detected within the transition period is stored in the HD 108, so that diagnosis using the log information stored in the HD 108 can detect the abnormality. Can judge the content.
This point will be explained in detail below. Note that inconveniences when an abnormality is detected during the transition period from normal mode (first mode) to energy saving mode (second mode) can occur even in information processing devices other than the MFP 100, so the following is explained below.

<About the information processing device 1>
FIG. 3 is a functional block diagram of the information processing device 1 (MFP 100). As shown in FIG. 3, the information processing device 1 includes a control section 10, a storage section 21, a processing section 22 (printing section 22A, reading section 22B), a detection section 23, an operation section 24, and a power supply operation section. 25 and a communication section 26.
Among the units, the processing unit 22, the operation unit 24, and the communication unit 26 are the operating unit 20 that is controlled by the control unit 10 and performs various operations.

The control unit 10 performs overall control of the information processing device 1 . The control unit 10 corresponds to the CPU 101 and MEM-P 102 in the MFP 100 in FIG. Note that the details of the control by the control unit 10 will be explained later.
The storage unit 21 can store various types of information. For example, the storage unit 21 can accumulate and store log information related to processing in the processing unit 22. The storage unit 21 corresponds to the HD 108 in the MFP 100 in FIG.
The processing unit 22 performs various processes depending on the content of the operation on the operation unit 24. In this embodiment, the processing section 22 includes a printing section 22A that prints on a recording medium, and a reading section 22B that reads an image recorded on the recording medium. The processing unit 22 corresponds to the printer unit 4 and scanner unit 2 in the MFP 100 in FIG.

The detection unit 23 detects a change in the state while the processing unit 22 is performing processing. The detection unit 23 detects a state different from the normal state when an abnormality occurs in the processing unit 22.
For example, it is assumed that the detection unit 23 is provided on the conveyance path of the recording medium and detects the presence or absence of the recording medium. In this case, the detection unit 23 outputs a detection signal indicating the presence of a recording medium over a predetermined time range during normal operation. On the other hand, the detection unit 23 outputs a detection signal indicating that the recording medium is present for a longer period of time than the above-mentioned time range in an abnormal situation where the conveyance speed of the recording medium becomes excessively slow.
The detection unit 23 corresponds to the sensors 4a of the printer unit 4 and the sensors 2a of the scanner unit 2 in the MFP 100 in FIG.

The operation unit 24 accepts operations from the user. For example, it accepts an operation to copy an image recorded on a recording medium, or accepts an operation to read an image recorded on a manuscript. The operation panel 140 in the MFP 100 in FIG. 2 corresponds to the operation unit 24.
The power operation unit 25 receives operations for supplying or stopping power to the information processing device 1 . The power button SW in the MFP 100 in FIG. 2 corresponds to the power operation unit 25.
The communication unit 26 communicates between the information processing device 1 and an external device (for example, the analysis server 200) that is communicatively connected. The communication unit 26 corresponds to the short-range communication circuit 120 and network I/F 150 in the MFP 100 in FIG.

Next, the control section 10 will be explained in detail. The control unit 10 includes a job control unit 11 , a storage control unit 12 , a diagnosis unit 13 , an operation reception unit 14 , a transition control unit 15 , an abnormality determination unit 16 , and a communication control unit 17 .

The job control unit 11 controls the processing (job) performed by the processing unit 22. For example, it controls printing on a recording medium by the printing section 22A, and controls reading of an image from a document by the reading section 22B.
The storage control unit 12 causes the storage unit 21 to store various information. For example, the storage control unit 12 causes the storage unit 21 to store log information used for diagnosis to determine the content of an abnormality that has occurred in the processing unit 22.
The log information is information used for diagnosis to determine the details of an abnormality that has occurred in the processing unit 22. For example, if there is an abnormality in the recording medium conveyance path of the printing section 22A (printer section 4) and the document conveyance path of the reading section 22B (scanner section 2) (conveyance system abnormality), log information is recorded in the detection section 23 (sensors 4a, 2a ) is used to detect the recording medium or document. In addition to the above-mentioned detection time, the log information is determined as appropriate depending on the type of abnormality.

The diagnostic unit 13 performs diagnosis to determine the nature of the abnormality that has occurred in the processing unit 22 based on the log information stored in the storage unit 21 .
The operation reception unit 14 performs a process of accepting operations on the operation unit 24 .
The transition control unit 15 monitors whether or not mode transition conditions are met, and shifts the mode when the mode transition conditions are met. For example, the transition control unit 15 monitors the operation on the power operation unit 25 in the normal mode, controls the transition to the power saving mode when the operation to transition to the power saving mode is performed, and controls the transition to the power saving mode, and when the power off operation is performed. Controls the transition to the power off state when the power is turned off. Further, in the normal mode, the transition control section 15 monitors the presence or absence of an operation on the operation section 24, and controls a transition to the energy saving mode when no operation is performed for a specified period of time.
The communication control unit 17 controls communication by the communication unit 26.

The abnormality determination unit 16 determines whether or not there is an abnormality in the operation unit 20 whose operation is controlled by the control unit 10 . Here, the abnormality will be explained. For convenience, the MFP 100, which is an example of the information processing device 1, will be described as an example.
FIG. 4 is a diagram showing the relationship between the classification of abnormalities and the necessity of storing log information. As shown in FIG. 4, abnormalities in the MFP 100 include, for example, abnormalities in the imaging system related to the creation of images (latent images, toner images), abnormalities in the transport system related to the transport of recording media and original documents, and There are fixing system abnormalities related to the fixing mechanism, communication system abnormalities related to communication with external devices such as the analysis server 200, and software abnormalities related to software executed by the CPU 101.

<About diagnosis by information processing device 1>
Next, diagnosis by the information processing device 1 will be explained. FIG. 5 is a timing chart explaining the operation of the information processing device. In FIG. 5, symbols t1 to t13 indicate timing.
As shown in FIG. 5, in the information processing device 1, when the processing unit 22 executes a process (job) (t1), the control unit 10 acquires log information corresponding to the executed process and stores it in the storage unit 21. (t2). Similarly, when the processing unit 22 executes the process (t3, t9), log information is stored in the storage unit 21 (t4, t10).

Taking the MFP 100 as an example, when the printer unit 4 prints on a recording medium, the recording medium to be printed is conveyed along a conveyance path, and a sensor (sensors 4a) arranged in the conveyance path Detected by. The CPU 101 acquires the passage time of the recording medium based on the detection signal of the sensor, and stores it in the HD 108 as log information.
Similarly, when the scanner section 2 reads an image from a document set on the DF, the document to be read is conveyed along a conveyance path and detected by a sensor (sensors 2a) disposed within the conveyance path. The CPU 101 acquires the passage time of the document based on the detection signal of the sensor, and stores it in the HD 108 as log information.

When the conditions for transitioning to the energy saving mode are satisfied in the normal mode (t5), the information processing device 1 then transitions to the energy saving mode (t6). Similarly, when the conditions for returning to the normal mode are satisfied in the energy saving mode (t7), the information processing device 1 then shifts to the normal mode (t8).
Taking the MFP 100 as an example, when the power button SW is pressed for less than a specified time in the normal mode, and when the operation panel 140 etc. is not operated for a specified time, the MFP 100 enters the energy saving mode. Transition. Similarly, in the energy saving mode, when the power button SW is pressed and when the operation panel 140 is operated, the normal mode is returned (shifted).

When the information processing device 1 determines that an abnormality has occurred in the operating unit (t11), it stores log information related to the abnormality in the storage unit 21 (t12). After that, diagnosis is performed using the log information stored in the storage unit 21 (t13).
Taking the MFP 100 as an example, when an abnormality occurs in the fixing unit (mechanism for fixing toner images on a recording medium) included in the printer unit 4, the CPU 101 acquires log information related to the abnormality (for example, temperature information of the fixing unit). and store it in the HD 108. After that, the CPU 101 reads the log information stored in the HD 108 and determines the content of the abnormality that has occurred in the fixing unit.

In the information processing device 1 described above, an abnormality may occur between the time when the mode transition condition is established and the time when the mode transition condition is satisfied until the transition to the energy saving mode. FIG. 6 is a timing chart illustrating a comparative example when an abnormality occurs between the time when the mode transition condition is satisfied (t21) and the transition to the energy saving mode (t24). In FIG. 6, symbols t21 to t24 indicate timing. d
In the comparative example, the control unit 10 (transition control unit 15) starts transition to the energy saving mode when the mode transition condition is satisfied in the normal mode (t21). For example, the control unit 10 (storage control unit 12) causes the nonvolatile storage unit 21 (HD 108, etc.) to store data required when returning to the normal mode. Further, the control unit 10 (migration control unit 15) stops the supply of power to only the minimum necessary devices. In the example of FIG. 6, the information processing device 1 stops supplying power to the storage unit 21 (t22).

The control unit 10 (abnormality determination unit 16, storage control unit 12) monitors the operating unit 20 for abnormalities even during the transition period (t21-t24) from the establishment of the mode transition condition to the power saving mode, and detects any abnormality. When an abnormality occurs, log information related to the abnormality is stored in the storage unit 21. However, in the comparative example, the control unit 10 determines whether there is an abnormality after the power supply to the storage unit 21 is stopped (t23). Therefore, even if the control unit 10 acquires log information related to an abnormality, it cannot store the log information in the storage unit 21.
As a result, in the comparative example, the storage unit 21 could not store log information related to the abnormality, and the control unit 10 (diagnosis unit 13) could not determine the details of the abnormality.

Therefore, in the information processing device 1 of the present embodiment, when an abnormality occurs in the operating unit 20 within the transition period, the transition to the power saving mode is delayed until the log information related to the abnormality is stored in the storage unit 21. There is.
A specific example will be described below. FIG. 7 is a timing chart explaining the operation of the first embodiment. In FIG. 7, symbols t31 to t38 indicate timing. Moreover, FIG. 7 shows the processing after the mode transition condition is satisfied.

In the example of FIG. 7, the transition control unit 15 starts transitioning to the energy saving mode when the transition condition is satisfied (t31). The abnormality determining unit 16 determines that an abnormality has occurred in the operating unit 20 within the transition period to the energy saving mode (abnormality determination, t32). The transition control unit 15 interrupts the transition to the energy saving mode based on the abnormality determination. The storage control unit 12 causes the storage unit 21 to store log information related to the abnormality that has occurred (t33).

In this embodiment, the storage control unit 12 causes the storage unit 21 to store log information selected according to the type of abnormality that has occurred.
As shown in FIG. 4, the storage control unit 12 determines not to store log information in the storage unit 21 regarding an abnormality in the imaging system and an abnormality in the transport system. This is because there is a high possibility that the same abnormality in the imaging system and transport system will occur again after returning to the normal mode, and it is sufficient to store log information when the same abnormality occurs again.
The storage control unit 12 determines that log information regarding the fixing system abnormality is to be stored in the storage unit 21 . The reason is that an abnormality in the fixing system has a large effect on the information processing apparatus 1 and requires prompt response.
The storage control unit 12 determines that log information for communication system abnormalities and software abnormalities is to be stored in the storage unit 21. The reason is that communication system abnormalities and software abnormalities may or may not occur, and it is necessary to understand the cause.

The transition control unit 15 monitors that the log information is stored in the storage unit 21, and restarts the transition to the energy saving mode as the log information is stored. As a result, the supply of power to the storage unit 21 is stopped (t34), and thereafter, the transition to the energy saving mode is completed (t35).
The transition control unit 15 monitors whether mode return conditions are satisfied in the energy saving mode. For example, the transition control unit 15 monitors the operation on the power operation unit 25 and the operation on the operation unit 24, and the transition control unit 15 monitors the operation on the power operation unit 25 and the operation unit 24. When an operation requesting the operation is performed, it is determined that the mode return condition is satisfied.

When the mode return condition is satisfied in the energy saving mode (t36), the transition control unit 15 performs return processing to the normal mode (t36-t37).
After returning to the normal mode, the diagnostic unit 13 converts the abnormality (t32) that occurred during the transition period from normal mode to energy saving mode (t31-t34) into the log information stored in the storage unit 21 during the transition period. Diagnose based on the information (t38).
In the example of FIG. 7, when an abnormality occurs (t32) during the transition period to energy saving mode (t31-t34), the information processing device 1 performs energy saving mode until log information related to the abnormality that has occurred is stored in the storage unit 21. Since the transition to the mode is delayed, when the energy saving mode returns to the normal mode (t37), diagnosis can be performed based on the log information stored in the storage unit 21 (t38).
Although FIG. 7 shows an example of transition from the normal mode to the energy saving mode, similar processing is performed also when transitioning from the normal mode to the power-off state.

<About the operation of the control unit 10>
The operation of the control unit 10 for realizing the above processing will be described below. FIG. 8 is a flowchart illustrating log information storage processing.
As shown in FIG. 8, the control unit 10 monitors the operating unit 20 for abnormalities (S101), and when an abnormality is detected (S101: Yes), the controller 10 is in the middle of transitioning to the energy saving mode or in the middle of power-off processing. (S102). When the control unit 10 determines that it is not in the middle of transition to the energy saving mode or in the middle of power off processing (S102: No), it performs a process of storing log information related to the abnormality in the storage unit 21 (S108), Finish the series of processing.

When the control unit 10 determines that it is in the middle of transitioning to the energy saving mode or in the process of powering off (S102: Yes), it determines whether the storage unit 21 is in a usable state (103). ). When the control unit 10 determines that the storage unit 21 is usable (S103: Yes), it performs a process of storing log information related to the abnormality in the storage unit 21 (S106), and then turns off the power to the storage unit 21. A process is performed to turn off (S107).

When the control unit 10 determines that the storage unit 21 is not in a usable state (S103: No), the control unit 10 determines whether the abnormality is of a type in which log information should be stored (S104). As explained in FIG. 4, the control unit 10 determines that log information should be stored for fixing system abnormalities, communication system abnormalities, and software abnormalities, and logs for imaging system abnormalities and transport system abnormalities. It is determined that the information does not need to be memorized.
When the control unit 10 determines that there is an abnormality that requires log information to be stored (S104: Yes), the control unit 10 puts the storage unit 21 into a usable state, for example, turns on the power of the storage unit 21 (S105). After that, the control unit 10 performs a process of storing log information related to the abnormality in the storage unit 21 (S106) and a process of turning off the power of the storage unit 21 (S107).
Further, if the control unit 10 determines that the abnormality is such that the log information does not need to be stored (S104: No), the control unit 10 ends the series of processing.

<Second embodiment>
In the first embodiment described above, the control unit 10 stores the log information in the storage unit 21 (HD 108), but the configuration is not limited to this. For example, an information processing device has multiple energy-saving levels (hereinafter referred to as energy-saving levels), and is equipped with multiple types of storage units that can store log information and have different energy-saving levels, so that log information can be stored according to the energy-saving level. You may select a storage unit to store the .
A second embodiment having such a configuration will be described below. FIG. 9 is a diagram for explaining the hardware configuration of the MFP according to the second embodiment, FIG. 10 is a diagram showing the relationship between the energy saving level and the on/off state of each part's power supply, and FIG. 11 is a diagram for explaining the hardware configuration of the MFP according to the second embodiment. It is a functional block diagram.
Note that in the description of the second embodiment, the same components as in the first embodiment are given the same reference numerals and the description thereof will be omitted.

As shown in FIG. 9, in the MFP 100 of the second embodiment, an operation panel 140 includes an operation control section 143, a RAM 144, and an embedded MultiMediaCard (eMMC) 145 in addition to a panel display section 141 and a panel operation section 142. This point differs from the MFP 100 of the first embodiment.
The operation control unit 143 is electrically connected to the panel display unit 141, the panel operation unit 142, the RAM 144, and the eMMC 145, and serves as the center of control for the operation panel 140.
The RAM 144 is used for loading programs for the operation control unit 143 and as a work memory.
The eMMC 145 is a storage that can store various types of information, and can also store log information.

As shown in FIG. 10, the MFP 100 of the second embodiment has three energy saving levels set.
Energy saving level 1 is the level that consumes the most energy among the three energy saving levels. At energy saving level 1, the MFP 100 stops supplying power to the printer section 4 and scanner section 2, and supplies power to the HD 108 and operation panel 140. That is, at energy saving level 1, log information can be stored in each of the HD 108 and the eMMC 145.
Energy saving level 2 is an intermediate level of energy consumption among the three energy saving levels. At energy saving level 2, MFP 100 stops supplying power to printer section 4, scanner section 2, and HD 108, and supplies power to operation panel 140. That is, at energy saving level 2, log information cannot be stored in the HD 108, but log information can be stored in the eMMC 145. Therefore, when the MFP 100 is at energy saving level 2, the eMMC 145 temporarily stores log information.
Energy saving level 3 is the level that consumes the least amount of energy among the three energy saving levels. At energy saving level 3, MFP 100 stops supplying power to printer section 4, scanner section 2, HD 108, and operation panel 140. That is, at energy saving level 3, log information cannot be stored in the HD 108 and eMMC 145.

As shown in FIG. 11, the information processing device 1 of the second embodiment includes a first storage section 21A and a second storage section 21B provided in the operation section 24, and the operation section 20 is a processing section. The information processing apparatus 1 differs from the information processing apparatus 1 of the first embodiment in that it includes a communication section 22 and a communication section 26.
The operation of the information processing device 1 of the second embodiment will be described below. FIG. 12 is a timing chart illustrating the operation of the information processing device 1. In FIG. 12, symbols t41 to t47 indicate timing. Moreover, FIG. 12 shows the processing after the mode transition condition is satisfied.

In the example of FIG. 12, the transition control unit 15 starts transition to the energy saving mode (level 2) when the transition condition is satisfied (t41). The abnormality determining unit 16 determines that an abnormality has occurred in the operating unit 20 during the period of transition to the energy saving mode (t41-t43) (abnormality determination, t42).
Since the storage control unit 12 cannot store the log information in the first storage unit 21A (HD 108) in the level 2 energy saving mode, it temporarily stores the log information in the second storage unit 21B (eMMC 145) (t44).
The transition control unit 15 monitors whether mode return conditions are satisfied in the energy saving mode, and when the mode return conditions are satisfied (t45), performs return processing to the normal mode (t45-t46).
After returning to the normal mode, the storage control unit 12 transfers the log information stored in the second storage unit 21B to the first storage unit 21A (HD 108) (t47). The log information transferred to the first storage unit 21A is used for diagnosis performed by the diagnosis unit 13.

Note that when changing the level of the energy saving mode in stages from level 1 to level 2 and from level 2 to level 3, the transition control unit 15 temporarily stores the log information at level 2 in the second storage unit 21B (eMMC 145). Delays transition to level 3 until memorization is complete.
In the second embodiment described above, even if the log information cannot be stored in the first storage unit 21A (HD 108), the log information may be temporarily stored in the second storage unit 21B (eMMC 145). This can prevent the inconvenience of unnecessarily long transition time to energy saving mode.

<Third embodiment>
In the first embodiment described above, the control unit 10 stores the log information in the storage unit 21 (HD 108), but the configuration is not limited to this. For example, if an information processing device is configured to be able to communicate with an external device equipped with a storage unit and a diagnostic unit, and an abnormality is detected within the transition period, the information processing device will not communicate with the external device until the log information is stored in the storage unit of the external device. The communication state between the two may be maintained.
A third embodiment having such a configuration will be described below. FIG. 13 is a diagram for explaining the hardware configuration of the analysis server of the third embodiment, and FIG. 14 is a functional block diagram of the information processing device and external device of the third embodiment.
In addition, also in the description of the third embodiment, the same components as in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

First, the analysis server 200 will be explained with reference to FIG. 13. The analysis server 200 shown in FIG. 13 is constructed by a computer, and includes a CPU 201, ROM 202, RAM 203, HD 204, HDD controller 205, display 206, external device connection I/F 208, network I/F 209, data bus 210, keyboard 211, It includes a pointing device 212, a DVD-RW (Digital Versatile Disk Rewritable) drive 214, and a media I/F 216.

Among these, the CPU 201 controls the overall operation of the analysis server 200. The ROM 202 stores programs used to drive the CPU 201, such as IPL (Initial Program Loader). RAM 203 is used as a work area for CPU 201. The HD 204 stores various data such as programs. The HDD controller 205 controls reading and writing of various data to the HD 204 under the control of the CPU 201. The display 206 displays various information such as a cursor, menu, window, characters, or images. External device connection I/F 208 is an interface for connecting various external devices. The external device in this case is, for example, a USB memory or a printer. The network I/F 209 is an interface for data communication using the network NW. The data bus 210 is an address bus, a data bus, etc. for electrically connecting each component such as the CPU 201.
Further, the keyboard 211 is a type of input means that includes a plurality of keys for inputting characters, numerical values, various instructions, and the like. The pointing device 212 is a type of input means for selecting and executing various instructions, selecting a processing target, moving a cursor, and the like. The DVD-RW drive 214 controls reading and writing of various data on the DVD-RW 213, which is an example of a removable recording medium. Note that it is not limited to DVD-RW, but may be DVD-R or the like. The media I/F 216 controls reading or writing (storage) of data to a recording medium 215 such as a flash memory.

As shown in FIG. 14, the third embodiment includes an information processing device 1A and an external device 1B communicably connected to the information processing device 1A via a network NW. In the third embodiment, an MFP 100 corresponds to the information processing device 1A, and an analysis server 200 corresponds to the external device 1B.
The information processing device 1A is different from the information processing device 1 of the first embodiment in that it does not include the storage unit 21 for storing log information, and that the control unit 10A does not include the diagnosis unit 13. They are different. The other configurations are the same as the information processing device 1 of the first embodiment, so the explanation will be omitted.

External device 1B includes a control section 10B, a storage section 21, and a communication section 26B.
The control unit 10B performs overall control of the external device 1B. The CPU 201, ROM 202, and RAM 203 in the analysis server 200 in FIG. 13 correspond to the control unit 10B.
The storage unit 21 can store various types of information. For example, the storage unit 21 can accumulate and store log information related to processing in the processing unit 22. The storage unit 21 corresponds to the HD 204 in the analysis server 200 in FIG.
The communication unit 26B communicates with the communication unit 26A of the information processing device 1. The network I/F 209 in the analysis server 200 in FIG. 13 corresponds to the communication unit 26B.
The control unit 10B includes a diagnosis unit 13 and a communication control unit 17B. The diagnostic unit 13 performs diagnosis to determine the nature of the abnormality that has occurred in the processing unit 22 based on the log information stored in the storage unit 21 . The communication control unit 17B controls communication by the communication unit 26B.

In the third embodiment, the information processing device 1A stores the acquired log information in the storage unit 21 of the external device 1B. Then, the diagnosis section 13 of the external device 1B is stored in the storage section 21 and performs diagnosis based on the log information.
When an abnormality occurs in the operating unit 20 during the transition from the normal mode to the energy saving mode or from the normal mode to the power-off state, the information processing device 1A stores log information related to the abnormality in the storage unit 21. The communication state between the communication unit 26A and the external device 1B (communication unit 26B) is maintained until the communication unit 26A and the external device 1B (communication unit 26B) are connected.
Furthermore, the storage control unit 12 causes the external device 1B to store log information selected according to the type of abnormality that has occurred. In other words, the communication control unit 17A transmits the log information selected by the storage control unit 12 to the external device 1B.

FIG. 15 is a diagram showing the relationship between the type of abnormality and the necessity of transmitting log information.
As shown in FIG. 15, the storage control unit 12 and the communication control unit 17A transmit log files to the external device 1B for abnormalities in the imaging system, transport system, and fixing system (log information is transmitted to the storage unit 21). The reason is that abnormalities in the imaging system, transport system, and fixing system are likely to require parts to be replaced, so log files are sent to the external device 1B for early diagnosis. ing.
The storage control unit 12 and the communication control unit 17A determine not to transmit the log file to the external device 1B (not to store the log information in the storage unit 21) in the case of a communication system abnormality or a software abnormality. The reason is that communication system abnormalities and software abnormalities may be resolved when a communication state is established again between the information processing device 1A and the external device 1B.
By performing the above control, it is possible to avoid unnecessary communication, and it is possible to suppress the inconvenience that the time required to transition to the energy saving mode and the time required to turn off the power is excessively long.

<About the operations of the information processing device 1A and external device 1B>
Next, the operations of the information processing device 1A (MFP 100) and the external device 1B (analysis server 200) will be described. FIG. 16 is a timing chart illustrating the normal mode operation of the third embodiment.
As shown in FIG. 16, in the information processing device 1A in the normal mode, the abnormality determination unit 16 monitors the presence or absence of an abnormality in the operating unit 20, and when an abnormality occurs in the operating unit 20, determines whether there is an abnormality (t51). . The storage control unit 12 acquires log information related to the abnormality that has occurred, and generates a log file (data for transmission) based on the log information (t52). Further, the communication control unit 17A controls the communication unit 26A to transmit the log file (t53).
On the other hand, the communication control unit 17B of the external device 1B receives the log file transmitted by the information processing device 1A (t61), and stores log information based on the log file in the storage unit 21 (t62). The diagnosis unit 13 diagnoses an abnormality that has occurred in the information processing device 1A based on the log information stored in the storage unit 21 (t63).

FIG. 17 is a timing chart illustrating the operation at the time of transition from the normal mode to the energy saving mode in the third embodiment.
As shown in FIG. 17, in the normal mode, in the information processing device 1A, the transition control unit 15 monitors whether the mode transition condition is satisfied, and starts mode transition when the mode transition condition is satisfied (t71). The abnormality determining unit 16 monitors whether an abnormality has occurred in the operating unit 20 even during the period of transition to the energy saving mode, and if an abnormality occurs, determines whether the abnormality exists (t73). The storage control unit 12 acquires log information related to the abnormality that has occurred, and generates a log file (data for transmission) based on the log information (t73). Further, the communication control unit 17A controls the communication unit 26A to transmit the log file to the external device 1B (t74).
The transition control unit 15 monitors that the log file is sent to the external device 1B, and restarts the transition to the energy saving mode as the log file is stored. As a result, the supply of power to the communication unit 26A is stopped, and the transition to the energy saving mode is completed (t75).

The external device 1B is capable of communicating with the information processing device 1A, and when a log file is transmitted from the information processing device 1A (t74), the communication control unit 17B receives the log file (t81). When the communication control unit 17B completes receiving the log file, it notifies the information processing device 1A to that effect. The information processing device 1A restarts the transition to the energy saving mode based on this notification.
The communication control unit 17B of the external device 1B causes the storage unit 21 to store log information based on the received log file (t82). The diagnostic unit 13 diagnoses an abnormality that has occurred in the information processing device 1A based on the log information stored in the storage unit 21 (t83).
In the example of FIG. 17, when an abnormality occurs (t72) during the transition period to the energy saving mode (t71-t75), the information processing device 1A is configured to ( Since the transition to the energy saving mode (until it is stored in the storage unit 21) is delayed, even if an abnormality occurs within the transition period, the external device 1B can diagnose the abnormality.
Although FIG. 17 shows an example of transition from normal mode to energy saving mode, similar processing is performed when transitioning from normal mode to power off state.

<About the operation of the control unit 10A>
Hereinafter, the operation of the control unit 10A for realizing the above-described processing will be explained. FIG. 18 is a flowchart illustrating log information storage processing.
As shown in FIG. 18, the control unit 10A monitors the operating unit 20 for abnormalities (S201), and when an abnormality is detected (S201: Yes), the controller 10A is in the middle of transitioning to the energy saving mode or in the middle of power off processing. (S202). When the control unit 10A determines that the transition to the energy saving mode is not in progress and the power off process is not in progress (S202: No), the control unit 10A generates a log file related to the abnormality and sends it to the analysis server 200 (S209). ), the series of processing ends.

When the control unit 10A determines that the transition to the energy saving mode or the power off process is in progress (S202: Yes), the control unit 10A determines whether communication with the external device 1B via the network NW is possible. It is determined whether or not (203). When the control unit 10A determines that communication with the external device 1B is possible (S203: Yes), the control unit 10A generates a log file related to the abnormality and performs a process of transmitting it to the analysis server 200 (S206).
When the control unit 10A determines that communication with the external device 1B is not possible (S203: No), the control unit 10A determines whether there is an abnormality that should cause the log file to be sent to the external device 1B (S204). As described with reference to FIG. 15, the control unit 10A sends log files to the external device 1B (stores the log information in the storage unit 21) for abnormalities in the imaging system, transport system, and fixing system. It is determined that the log file will not be transmitted to the external device 1B (the log information will not be stored in the storage unit 21) for communication system abnormalities and software abnormalities.

When the control unit 10A determines that there is an abnormality that should cause a log file to be transmitted (S204: Yes), the control unit 10A starts network communication with the external device 1B (S205). In other words, the control unit 10A enables communication between the communication unit 26A of the information processing device 1A and the communication unit 26B of the external device 1B via the network NW.
Next, the control unit 10A performs a process of generating a log file related to the abnormality and transmitting it to the analysis server 200 (S206).
If the control unit 10A determines that there is no abnormality that should cause the log file to be transmitted (S204: No), or after transmitting the log file to the analysis server 200 in S206, it stops network communication with the external device 1B. (S207), the transition to the energy saving mode or the power off state is restarted (S208), and the series of processing ends.
