[0061]
Further, the CPU 323 serves as a state detection unit according to the present invention. For example, when a failure occurs in the function of the reader (scanner) unit 1 or a failure occurs in the function of the feeder 189, the reader unit is connected via the I / F 322. The information can be received from 1 and detected. Further, when a failure occurs in the printer unit 2 or a failure occurs in the finisher unit 190, the information can be received from the printer unit 2 through the I / F 327 and detected. Similarly, when a failure occurs in each function of the network processing unit 7, the facsimile unit 4, and the PDL development unit 8, the information can be received from each through the I / F 320 and detected by the CPU 323.

Then, an OK key 604 is pressed to confirm the selection.
[0073]
Hereinafter, the control processing procedure in the first embodiment of the image forming apparatus of the present invention will be described with reference to the flowchart of FIG.
[0074]
FIG. 6 is a flowchart showing a first control processing procedure in the image forming apparatus of the present invention. This control is performed mainly by the CPU 323 shown in FIG. S101 to S107 indicate each step.
[0075]
First, in step S101, the CPU 323 determines whether a device failure has been detected. When a failure occurs in the reader unit 1 (scanner) or when a failure occurs in the feeder 189, the reader unit 1 notifies the CPU 323 via the I / F 322, and a failure occurs in the printer unit 2. Alternatively, when a failure occurs in the finisher 190 or when a failure occurs in the deck 150, the printer unit 2 notifies the CPU 323 via the I / F 327. When a failure occurs in the facsimile, a failure occurs in the network board, or a failure occurs in the PDL expansion unit, the I / F 320 is sent from the facsimile unit 4, the network processing unit 7, or the PDL expansion unit 8, respectively. Through the CPU 323.
[0076]
If a failure is detected in step S101, the process proceeds to step S102, and an error code of the failure when a failure occurs is displayed on the operation unit 500. In step S103, a display for allowing the user to select whether or not to invalidate the displayed function is performed on the failure notification and degradation selection screen shown in FIG.
[0077]
In FIG. 5, a failure occurs in the finisher function, “540” is displayed as an error code, and the user is prompted to press the degeneration selection keys 602 and 603 of “Yes” or “No” to disable this function. Urging to.
[0078]
Next, in step S104, it is determined whether the function in which the failure is detected (displayed function) has been invalidated, that is, whether the function has been degraded. In order to disable the function, the displayed function is disabled by pressing the “Yes” reduction selection key 602 and then pressing the OK key 604. In the example of FIG. 5, the finisher function is disabled.
[0079]
If it is determined in step S104 that the function in which the failure is detected (displayed function) is invalidated (degenerated), the function in which the failure is detected (displayed function) in step S106, the finisher in FIG. In step S107, the function is disabled, the error code and the degenerate state are displayed on the status line 540 shown in FIG. 4, and the process ends. FIG. 4 shows a state where an error code 540 is generated due to a failure of the finisher function and the finisher function is degenerated.
[0080]
On the other hand, if it is determined in step S104 that the function in which the failure is detected (displayed function) is not invalidated (does not degenerate), that is, the “NO” degeneration selection key 603 is pressed and the OK key 604 is pressed. If the button is pressed, in step S105, “Please turn the power off / on” is displayed around the center of the operation unit screen, and the process is terminated.
[0081]
Here, the reason for displaying the instruction to turn off / on the power is, for example, a communication error such as noise between the finisher 190 and the printer 2, and the error may be displayed. There is also a possibility that an error will not occur. If the user makes such a determination, “No” is selected and the power is turned OFF / ON. If the same error occurs even after the power is turned off and on many times, “Yes” may be selected in step S104 to degenerate.
[0082]
As described above, according to the image forming apparatus of the present invention, even when a failure such as a lamp lighting error occurs in a part of the function of the image forming apparatus, for example, the scan function, the user disables the scan function by the operation unit. By selecting to do so, it is possible to disable only the scanning function with a failure without disabling the entire device as in the conventional case. Other functions such as the print function remain valid, and the user can use functions such as printing an image stored in the hard disk in the device or receiving print data from an external computer for printing. .
[0083]
As a result, for some users, when some functional failures occur, the problem of inconvenience caused by stopping the entire device can be resolved, and other functions can be continued immediately. The effect that it can be used is born. Furthermore, even after disabling some of the functions, the result of the detected failure (E code) is kept displayed on a part of the operation unit, and the state of which function is disabled is displayed on the operation unit. For example, all the users who use the image forming apparatus can know the reason why the scanner is invalid, and it is possible to surely understand why the scanner is invalid.
[0084]
Furthermore, by leaving the display of the E code, which is the cause of the invalidation, as it is in a part of the operation unit, it becomes effective as a judgment material for the service person to determine the procedure for repairing the failure. In other words, it is difficult to find the cause if only the display in a state where the scanning function is disabled, and such a problem can be avoided. In this way, convenience for the user and maintenance for the service person are dramatically improved.
[0085]
Furthermore, even if some functions of the scanner etc. become invalid, by enabling other functions such as printing etc., the entire device has been stopped so far. Until the man completes the repair of the scanner trouble, the printer cannot be used, and the toner, paper, and counter fees that could not be earned during that time can be earned by the present invention, which is also a great benefit for manufacturers and sales companies Will occur.
[0086]
Further, convenience can be improved by allowing the user to select whether or not to disable the function in which the failure has occurred. For example, if a user repeatedly turns off and on the main power supply when a failure occurs, the failure may not occur. Therefore, if you want to repeat the main power OFF and ON when a failure occurs, you can repeat the main power OFF and ON, etc. without performing the operation to disable the function that caused the failure, causing the failure In addition, when the main power supply is turned OFF and ON repeatedly, if the same failure occurs again, it can be said that the function in which the failure has occurred is invalidated.
[0087]
As a result, the number of cases in which a service person is called unnecessarily due to the first occurrence of a failure is reduced. For example, if the main power supply is turned off and on repeatedly, the guidance when the failure disappears is specified in the user's manual or when the failure occurs. If it is displayed on the operation unit and prompting the user, it is possible to reduce labor and labor costs of the service person.
[0088]
[Second Embodiment]
In the first embodiment, when a failure is detected, a configuration has been described in which whether or not the function in which the failure is detected is disabled (degenerate) is manually selected. However, the function in which the failure is detected is automatically selected. You may comprise so that it may become invalid (degeneration). The embodiment will be described below.
[0089]
Hereinafter, the control processing procedure in the second embodiment of the image forming apparatus of the present invention will be described with reference to the flowchart of FIG.
[0090]
FIG. 7 is a flowchart showing a second control processing procedure in the image forming apparatus of the present invention, and this control is performed mainly by the CPU 323 shown in FIG. Note that S201 to S205 indicate each step.
[0091]
First, in step S201, the CPU 323 determines whether a device failure is detected. When a failure occurs in the reader unit 1 (scanner) or when a failure occurs in the feeder 189, the reader unit 1 notifies the CPU 323 via the I / F 322, and a failure occurs in the printer unit 2. Alternatively, when a failure occurs in the finisher 190, or when a failure occurs in the deck 150, the printer unit 2 notifies the CPU 323 via the I / F 327. When a failure occurs in the facsimile, a failure occurs in the network board, or a failure occurs in the PDL expansion unit, the I / F 320 is sent from the facsimile unit 4, the network processing unit 7, or the PDL expansion unit 8, respectively. Through the CPU 323.
[0092]
If a failure is detected in step S201, the process proceeds to step S202, and an error code of the failure when a failure occurs is displayed on the operation unit 500. Here, the same display as the failure message 601 shown in FIG. 5 is performed.
[0093]
Next, in step S203, it is determined whether a predetermined time, for example, 10 seconds has elapsed, and the process waits until it elapses. That is, a fault error is displayed on the operation unit for at least that time. After a certain period of time, in step S204, the function that is the failure part, for example, the finisher function is invalidated. In step S205, the error code and the degenerate state are displayed on the status line 540 in FIG. . FIG. 4 shows a state where an error code 540 is generated due to a failure of the finisher function and the finisher function is degenerated.
[0094]
With the above processing, the image forming apparatus according to the present invention can automatically disable the scan function even if a failure such as a lamp lighting error occurs in a part of the function of the image forming apparatus, for example, the scan function. It is possible to automatically disable only the faulty scan function without disabling the entire device as in the prior art. Other functions such as the print function remain valid, and the user can use functions such as printing an image stored in the hard disk in the device or receiving print data from an external computer for printing. .
[0095]
As a result, when a failure of some functions occurs for the user as in the past, it is possible to eliminate the inconvenience of being inconvenienced by stopping the entire device, and other functions can be There is no operation, and there is an effect that it can be used automatically and immediately.
[0096]
Furthermore, even after some of the functions are automatically disabled, the detected failure result (E code) remains displayed on a part of the operation unit, and which function is disabled Is displayed on the operation unit, for example, all the users who use the image forming apparatus can know the reason why the scanner is invalid, and why the scanner is invalid even if the scanner is automatically invalidated. There is an effect that the reason is surely understood.
[0097]
Further, by leaving the display of the E code that is the cause of the invalidity as it is in a part of the operation unit, it becomes effective as a determination material for the service person to determine the procedure for repairing the failure. In other words, it is difficult to find the cause if the display is simply in a state where the scan function is disabled, and such a problem can be avoided.
[0098]
In this way, convenience for the user and maintenance for the service person are dramatically improved. Furthermore, even if some functions of the scanner etc. become invalid, by enabling other functions such as printing etc., the entire device has been stopped so far. Until the man completes the repair of the scanner trouble, the printer cannot be used, and the toner, paper, and counter charges that could not be earned according to the present invention can be earned according to the present invention. Profits are generated.
[0099]
[Third Embodiment]
In the first embodiment, the configuration in which the function in which the failure is detected is manually degenerated, and in the second embodiment, the configuration in which the function in which the failure is detected is automatically degenerated. However, either the manual degeneration or the automatic degeneration is described. It may be configured to be settable in advance. The embodiment will be described below.
[0100]
FIG. 8 is a schematic diagram showing an example of a reduction switching screen that is one of user mode setting screens according to the third embodiment of the present invention, corresponding to the manual reduction and automatic reduction switching screens shown in FIG. When the user mode key 503 is pressed, it is displayed on the display screen of the operation unit 500.
[0101]
In the figure, reference numeral 610 denotes a manual key, which is pressed to manually set a function for which a failure has been detected. Reference numeral 611 denotes an automatic key which is pressed to set a function in which a failure is detected so as to automatically degenerate. Reference numeral 612 denotes a return key, which is pressed to confirm selection of the manual key 610 or the automatic key 611 and return to the previous screen. Reference numeral 613 denotes a next key which is pressed when moving to a screen for other setting items of the user mode.
[0102]
Hereinafter, a control processing procedure in the third embodiment of the image forming apparatus of the present invention will be described with reference to the flowchart of FIG.
[0103]
FIG. 9 is a flowchart showing a third control processing procedure in the image forming apparatus of the present invention, and this control is performed mainly by the CPU 323 shown in FIG. S301 to S309 indicate each step.
[0104]
First, in step S301, the CPU 323 determines whether a device failure has been detected. When a failure occurs in the reader unit 1 (scanner) or when a failure occurs in the feeder 189, the reader unit 1 notifies the CPU 323 via the I / F 322, and a failure occurs in the printer unit 2. Alternatively, when a failure occurs in the finisher 190, or when a failure occurs in the deck 150, the printer unit 2 notifies the CPU 323 via the I / F 327. When a failure occurs in the facsimile, a failure occurs in the network board, or a failure occurs in the PDL expansion unit, the I / F 320 is sent from the facsimile unit 4, the network processing unit 7, or the PDL expansion unit 8, respectively. Through the CPU 323.
[0105]
If a failure is detected in step S301, the process proceeds to step S302, and an error code of the failure when a failure occurs is displayed on the operation unit 500. Here, the same display as the failure message 601 shown in FIG. 5 is performed.
[0106]
Next, in step S303, it is determined whether the setting state is manual degeneration or automatic degeneration. As described with reference to FIG. 6 in the second embodiment, the manual degeneration is performed by allowing the user to select whether or not to disable the function. On the other hand, the automatic degeneration is the third embodiment. In FIG. 8, the function in which the failure has occurred is automatically disabled after a certain time.
[0107]
This manual reduction or automatic reduction is selected in advance by the user shown in FIG. 4 pressing the user mode key 503 to display the user mode setting screen shown in FIG. Specifically, when the manual key 610 is pressed and the return key 612 is pressed, manual degeneration is performed, and when the automatic key 611 is pressed and the return key 612 is pressed, the automatic degeneration is set.
[0108]
If it is determined in step S303 that it is not manual degeneration, that is, automatic degeneration, in step S309, it is determined whether a certain time, for example, 10 seconds has elapsed, waits until it elapses, and it is determined that it has elapsed Shifts to step S307, automatically disables the failure function, and proceeds to step S308.
[0109]
On the other hand, if it is determined in step S303 that manual degeneration is performed, in step S304, the failure notification and degeneration selection screen shown in FIG. 5 is displayed to allow the user to select whether to invalidate the displayed function.
[0110]
In FIG. 5, a failure occurs in the finisher function, “540” is displayed as an error code, and the user is prompted to press the degeneration selection keys 602 and 603 of “Yes” or “No” to disable this function. Urging to.
[0111]
Next, in step S305, it is determined whether or not the function in which the failure is detected (displayed function) has been invalidated, that is, whether or not the function has been degraded. In order to disable the function, the displayed function is disabled by pressing the “Yes” reduction selection key 602 and then pressing the OK key 604. In the example of FIG. 5, the finisher function is disabled.
[0112]
If it is determined in step S305 that the function (displayed function) in which the failure is detected is invalidated (degenerated), the function (displayed function) in which the failure is detected in step S307, the finisher in FIG. The function is disabled and the process proceeds to step S308.
[0113]
Next, in step S308, the error code and the status of degeneration are displayed on the status line 540 shown in FIG. 4, and the process ends. FIG. 4 shows a state where an error code 540 is generated due to a failure of the finisher function and the finisher function is degenerated.
[0114]
On the other hand, if it is determined in step S305 that the function in which the failure is detected (displayed function) is not invalidated (does not degenerate), that is, the “NO” degeneration selection key 603 is pressed and the OK key 604 is pressed. If the button has been pressed, in step S306, “Please turn the power off / on” is displayed around the center of the operation unit screen, and the process ends.
[0115]
Here, the reason for displaying the instruction to turn off / on the power is, for example, a communication error such as noise between the finisher 190 and the printer unit 2, and the error may be displayed. Then, there is a possibility that an error does not occur. When the user makes such a determination, “No” is selected and the power is turned OFF / ON. If the same error occurs even after the power is turned off and on many times, “Yes” may be selected in step S305 to degenerate.
[0116]
As described above, according to the image forming apparatus of the present invention, even when a failure such as a lamp lighting error occurs in a part of the function of the image forming apparatus, for example, the scan function, the user invalidates the scan function using the operation unit. The service person or the user can select in advance to make the selection (manual degeneration) or automatically disable the scan function (automatic degeneration).
[0117]
Therefore, as in the past, it is possible to invalidate only the scanning function with a failure without invalidating the entire device. Other functions such as the print function remain valid, and the user can use functions such as printing an image stored in the hard disk in the device or receiving print data from an external computer for printing. . As a result, when a failure occurs in some functions as in the past, it is possible to eliminate the inconvenience of being inconvenienced by stopping the entire device, and other functions can be continued immediately. The effect that it can be used is born.
[0118]
Furthermore, even after disabling some of the functions, the result of the detected failure (E code) is kept displayed on a part of the operation unit, and the state of which function is disabled is displayed on the operation unit. For example, all the users who use the image forming apparatus can know the reason why the scanner is invalid and can surely know the reason why the scanner is invalid.
[0119]
Further, by leaving the display of the E code that is the cause of the invalidity as it is in a part of the operation unit, it becomes effective as a determination material for the service person to determine the procedure for repairing the failure. In other words, it is difficult to find the cause if only the display in a state where the scanning function is disabled, and such a problem can be avoided. In this way, convenience for the user and maintenance for the service person are dramatically improved.
[0120]
Furthermore, even if some functions of the scanner etc. become invalid, by enabling other functions such as printing etc., the entire device has been stopped so far. Until the man completes the repair of the scanner trouble, the printer cannot be used, and the toner, paper, counter fee that could not be earned during that time can be earned according to the present invention, and also for manufacturers, sales companies, etc. There are significant benefits.
[0121]
Further, when the manual degeneration is selected, the convenience can be improved by allowing the user to select whether or not to disable the function in which the failure has occurred. For example, if a user repeatedly turns off and on the main power supply when a failure occurs, the failure may not occur. Therefore, if you want to repeat the main power OFF and ON when a failure occurs, you can repeat the main power OFF and ON, etc. without performing the operation to disable the function that caused the failure, causing the failure In addition, when the main power supply is turned OFF and ON repeatedly, if the same failure occurs again, it can be said that the function in which the failure has occurred is invalidated.
[0122]
As a result, the number of cases in which a service person is called unnecessarily due to the first occurrence of a failure is reduced. For example, if the main power supply is turned off and on repeatedly, the guidance when the failure disappears is specified in the user's manual or when the failure occurs. By prompting the user by displaying on the operation unit, there is an effect that it is possible to reduce labor and labor costs of the service person.
[0123]
In addition, by selecting the automatic degeneration, if a failure occurs, the function can be automatically disabled immediately without any user operation, so that convenience for the user is improved. Since manual reduction or automatic reduction can be selected in advance by the user or the service person using the operation unit, the manual reduction or the automatic reduction can be performed according to the purpose of the user or the service person, and the convenience is improved.
[0124]
[Fourth Embodiment]
In the third embodiment, the configuration in which either manual degeneration or automatic degeneration is set in advance has been described. However, manual degeneration or automatic degeneration may be automatically switched according to the type of failure. The embodiment will be described below.
[0125]
Hereinafter, the control processing procedure in the fourth embodiment of the image forming apparatus of the present invention will be described with reference to the flowchart of FIG.
[0126]
FIG. 10 is a flowchart showing a fourth control processing procedure in the image forming apparatus of the present invention, and this control is performed mainly by the CPU 323 shown in FIG. S401 to S409 indicate each step.
[0127]
First, in step S401, the CPU 323 determines whether a device failure has been detected. When a failure occurs in the reader unit 1 (scanner) or when a failure occurs in the feeder 189, the reader unit 1 notifies the CPU 323 via the I / F 322, and a failure occurs in the printer unit 2. Alternatively, when a failure occurs in the finisher 190, or when a failure occurs in the deck 150, the printer unit 2 notifies the CPU 323 via the I / F 327. When a failure occurs in the facsimile, a failure occurs in the network board, or a failure occurs in the PDL expansion unit, the I / F 320 is sent from the facsimile unit 4, the network processing unit 7, or the PDL expansion unit 8, respectively. Through the CPU 323.
[0128]
If a failure is detected in step S401, the process proceeds to step S402, and an error code of the failure when a failure occurs is displayed on the operation unit 500. Here, the same display as the failure message 601 shown in FIG. 5 is performed.
[0129]
Next, in step S403, it is determined whether the content of the failure is content that should be manually reduced or content that should be automatically reduced. The contents to be manually reduced are errors that may cause no error to be displayed when the power is turned OFF / ON. For example, if there is an error on the communication line between the printer and the finisher, there is a possibility that noise has occurred on the line, and there is a possibility that the error will not occur when the power is turned OFF / ON. The contents to be automatically reduced are those that are unlikely to cause an error even when the power is turned OFF / ON. For example, motor abnormality, sensor abnormality, and the like.
[0130]
If it is determined in step S403 that manual degeneration should not be performed, that is, automatic degeneration should be performed, it is determined in step S409 whether a certain period of time, for example, 10 seconds has elapsed, and waits until elapses. If it is determined, the process proceeds to step S407, the failure function is automatically disabled, and the process proceeds to step S408.
[0131]
On the other hand, if it is determined in step S403 that manual reduction should be performed, in step S404, the failure notification and reduction selection screen shown in FIG. Display.
[0132]
In FIG. 5, a failure occurs in the finisher function, “540” is displayed as an error code, and the user is prompted to press the degeneration selection keys 602 and 603 of “Yes” or “No” to disable this function. Urging to.
[0133]
Next, in step S405, it is determined whether or not the function in which the failure is detected (displayed function) has been invalidated, that is, whether or not the function has been degraded. In order to disable the function, the displayed function is disabled by pressing the “Yes” reduction selection key 602 and then pressing the OK key 604. In the example of FIG. 5, the finisher function is disabled.
[0134]
If it is determined in step S405 that the function (displayed function) in which the failure is detected is invalidated (degenerated), the function (displayed function) in which the failure is detected in step S407, the finisher in FIG. The function is disabled and the process proceeds to step S408.
[0135]
Next, in step S408, the error code and the degenerated state are displayed on the status line 540 shown in FIG. 4, and the process is terminated. FIG. 4 shows a state where an error code 540 is generated due to a failure of the finisher function and the finisher function is degenerated.
[0136]
On the other hand, if it is determined in step S405 that the function in which the failure is detected (displayed function) is not invalidated (does not degenerate), that is, the “NO” degeneration selection key 603 is pressed and the OK key 604 is pressed. If the button is pressed, in step S406, “Please turn the power off / on” is displayed around the center of the operation unit screen, and the process is terminated.
[0137]
Here, the reason for displaying the instruction to turn off / on the power is, for example, a communication error such as noise between the finisher 190 and the printer unit 2, and the error may be displayed. Then, there is a possibility that an error does not occur. When the user makes such a determination, “No” is selected and the power is turned OFF / ON. If the same error occurs even after the power is turned off and on many times, “Yes” may be selected in step S405 to degenerate.
[0138]
In the first to fourth embodiments, the electrophotographic method is taken as an example of the printing method of the image forming apparatus. However, the present invention is not limited to this, and an inkjet method, a thermal transfer method, and a thermal method. Other printing methods such as an electrostatic method, a discharge destruction method, and a sublimation method may be used.
[0139]
As described above, in the image forming apparatus according to the present embodiment, even if a failure such as a lamp lighting error occurs in a part of the function of the image forming apparatus, for example, the scan function, the user disables the scan function by the operation unit. It is possible to automatically select whether to make a selection (manual degeneration) or automatically disable the scan function (automatic degeneration) depending on the type of failure.
[0140]
For example, in the case of a communication error between the scanner and the document feeder, there is a possibility that an error may have occurred on the communication line due to noise or the like. In this case, it is more convenient to use manual degeneration. In addition, an error that has a high possibility of causing an error again when the main switch is turned off and on, such as a lamp lighting error, is more convenient when automatic degeneration is performed. By automatically selecting these manual reduction and automatic reduction according to the type of error that has occurred, overall convenience is improved.
[0141]
Further, as in the past, when a scan function error occurs, only the faulty scan function can be disabled without disabling the entire device. Other functions such as the print function remain valid, and the user can use functions such as printing an image stored in the hard disk in the device or receiving print data from an external computer for printing. .
[0142]
As a result, for some users, when some functional failures occur, the problem of inconvenience caused by stopping the entire device can be resolved, and other functions can be continued immediately. The effect that it can be used is born. Furthermore, even after disabling some of the functions, the result of the detected failure (E code) is kept displayed on a part of the operation unit, and the state of which function is disabled is displayed on the operation unit. For example, all the users who use the image forming apparatus can know the reason why the scanner is invalid, and the conventional problem that the reason why the scanner is invalid can not be solved.
[0143]
Furthermore, by leaving the display of the E code, which is the cause of the invalidation, as it is in a part of the operation unit, it becomes effective as a judgment material for the service person to determine the procedure for repairing the failure. In other words, it is difficult to find the cause if the display is simply in a state where the scan function is disabled, and such a problem can be avoided.
[0144]
In this way, convenience for the user and maintenance for the service person are dramatically improved. Furthermore, even if some functions of the scanner etc. become invalid, by enabling other functions such as printing etc., the entire device has been stopped so far. Until the man completes the repair of the scanner trouble, the printer cannot be used, and the toner, paper, and counter charges that could not be earned according to the present invention can be earned according to the present invention. Profits are generated.
[0145]
Furthermore, when the manual degeneration is selected, convenience can be improved by allowing the user to select whether or not to disable the function in which the failure has occurred. For example, if a user repeatedly turns off and on the main power supply when a failure occurs, the failure may not occur.
[0146]
Therefore, if you want to repeat the main power OFF and ON when a failure occurs, you can repeat the main power OFF and ON, etc. without performing the operation to disable the function that caused the failure, causing the failure In addition, when the main power supply is turned OFF and ON repeatedly, if the same failure occurs again, it can be said that the function in which the failure has occurred is invalidated. As a result, the number of cases in which a service person is called unnecessarily due to the first occurrence of a failure is reduced. For example, if the main power supply is turned off and on repeatedly, the guidance when the failure disappears is specified in the user's manual or when the failure occurs. By prompting the user by displaying on the operation unit, there is an effect that it is possible to reduce labor and labor costs of the service person.
[0147]
In addition, by selecting the automatic degeneration, if a failure occurs, the function can be automatically disabled immediately without any user operation, so that convenience for the user is improved. Since manual reduction or automatic reduction can be selected in advance by the user or the service person using the operation unit, the manual reduction or the automatic reduction can be performed according to the purpose of the user or the service person, and the convenience is improved.
[0148]
The device automatically selects these manual degeneration and automatic degeneration according to the type of error, thereby improving the overall convenience.
[0149]
