Description

  The present invention relates to a printing apparatus.

  There is a demand for an office machine (image forming apparatus) with high power saving effect in an office at present. Therefore, the MFP (Multi Function) can reduce the effective power more by turning off the power of the image forming apparatus and not using the power saving mode of the entire image forming apparatus as well as ON / OFF of the image forming apparatus as a whole. Printer) is considered.

  For example, in Patent Document 1, power saving is achieved by turning off the power supply of the fixing unit and the sheet feeding system during the fax reception operation. During printing operation of the printer, the power control of the respective units of the apparatus is performed according to the selected application function such as power saving by turning off the power of the operation panel and the image scanner unit.

JP 2001-201986 A

  In order to obtain a high power saving effect in an image forming apparatus, for example, it is conceivable that a device such as a printer or a scanner turns on the power of the device at the time of use and turns off the power immediately after the use.

However, depending on the device, the initialization process after turning on the power takes time, and therefore, a wait time occurs each time the user uses an arbitrary function. That is, for a user who frequently uses a device requiring a long time for initialization, the user responsiveness of the image forming apparatus at the start of use is significantly reduced.
Such a situation may be caused by the screen setting that the user should execute in the image forming apparatus, the authority to select the function set by the user, the history of the functions used in the image forming apparatus of the user to be authenticated, etc. Is also a problem that occurs in the same way. That is, in the above-mentioned situation, power supply to the device requested by the user is not started until the controller of the image forming apparatus recovers, and the user accordingly has a wait time. Also, if it is possible to execute all functions independently of the user's request, power will be supplied to all devices, and unnecessary power may be consumed for unnecessary functions. It will

  The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a device specified by a job processing function to be executed by a user in parallel with the transition of the controller to the standby state. To provide a mechanism to start the power supply of

  In order to achieve the above object, the present invention is a printing apparatus capable of transitioning to a power saving state in which the display unit is not displayed, and displayed on the display unit when the printer engine and the power saving state are restored. A display control unit configured to display the screen set by the setting unit on the display unit according to a setting unit configured to set a screen; and a user operation configured to restore the printing apparatus from the power saving state; And control means for determining whether to supply power to the printer engine based on the screen.

According to the present invention, power supply to the device specified by the job processing function to be executed by the user can be started in parallel with the transition of the controller to the standby state.
Further, since power supply to devices other than those required by the user can be restricted, power saving effects can be expected, and job processing requested by the user can be executed promptly after the controller shifts to the standby state.

<Description of system configuration>
First Embodiment
FIG. 1 is a block diagram for explaining the arrangement of an image forming apparatus according to the present embodiment. In the present embodiment, a printer device 4 that executes a print processing function as a device that executes job processing, a scanner device 2 that executes a scan processing function, and an image processing function that is performed for the printer device 4 or the scanner device 2 are executed. Although the example provided with the image processing unit 5 is shown, it is not limited to this. The image forming apparatus shown in the present embodiment is provided with a control device (controller) 3 that controls job processing performed using the plurality of devices that perform different processing.

  In FIG. 1, a scanner 2 optically reads an image from an original and converts it into a digital image. A printer 4 outputs a digital image to a paper device. An operation unit 8 includes a display unit and an instruction unit, and receives an operation instruction to the apparatus from the user. A FAX 7 transmits digital images to a telephone line or the like.

  A hard disk 14 stores digital images and control programs. A controller 3 controls each device connected to the bus to execute job processing. The image forming apparatus 1 can also perform input / output of digital images, issuance of a job, instruction of devices, etc. from the computer 10 via the LAN 9.

  The scanner device 2 comprises a document feeding unit 11 capable of automatically replacing a bundle of documents automatically, and a scanner unit 12 capable of optically scanning a document and converting it into a digital image, and the converted image data is a controller Sent to 3

  The printer 4 includes a sheet feeding unit 18 capable of sequentially feeding a sheet of paper one by one, a marking unit 16 for printing image data on the fed sheet, and a delivery unit for delivering the sheet after printing It consists of seventeen.

  The controller 3 has a CPU 13 and transmits / receives and stores image data with the scanner device 2 and the printer device 4. That is, the controller 3 temporarily stores the image data received from the scanner device 2 in the memory 15. Thereafter, storing the image data in the hard disk 14 completes the scanning and storage of the image.

The controller 3 can perform print output by temporarily storing image data from the hard disk 14 in the memory 15 and transmitting the image data from the memory 15 to the printer device 4. Further, the image processing unit 5 has a general-purpose image processing unit 19, and the general-purpose image processing unit 19 stores, in the memory 15, the image data stored in the memory 15 after processing such as reduction, for example. The general-purpose image processing unit 19 is used in various situations as needed.
The image forming apparatus 1 has an operation unit 8 controlled by the controller 3. The CPU 13 interprets an operator operation or an instruction from the LAN 9, and can execute various job processes described below.
An example is described below.
Copy job processing
The image read from the scanner device 2 is stored in the hard disk 14, and at the same time printing is performed using the printer device 4.

[Image transmission job processing]
The image read from the scanner device 2 is stored in the hard disk 14 and transmitted to the computer 10 via the LAN 9.
[Image storage job processing]
The image read from the scanner device 2 is stored in the hard disk 14, and image transmission and image printing are performed as necessary.
[Image print job processing]
For example, the page description language transmitted from the computer 10 is analyzed and printed by the printer device 4.

[FAX reception job processing]
The fax image received from the fax machine 7 is stored in the hard disk 14 and printed using the printer device 4 at the same time.
[FAX transfer job processing]
The fax image received from the fax machine 7 is stored in the hard disk 14 and simultaneously transferred to the computer 10 or the like via the LAN 9.
[FAX Memory Reception Job Processing]
The fax image received from the fax machine 7 is stored in the hard disk 14 and waits for reference from the operator.

[FAX transmission job processing]
The image read from the scanner device 2 is stored in the hard disk 14 and simultaneously transmitted from the FAX device 7 to the public line.

  The hard disk 14 is interposed in many cases in order to recover from an abnormal state such as a failure of a job or a power failure.

The power supply device 6 is a device that supplies power in the image forming apparatus 1. When the power supply 6 is turned off, the AC power 29 is isolated by the switch 30. In the power supply device 6, when the switch 30 is turned ON, AC power is supplied to the AC-DC converter 20, and DC power is generated.
The power supply device 6 can perform four independent power control of the entire device according to an instruction of the CPU 13.

That is, by the switch control from the CPU 13, the power of the controller unit power 25 can be turned off / on. Similarly, the power of the printer unit power 28, the scanner unit power 26, and the general-purpose image processing unit power 27 can be turned off / on.
The CPU 13 appropriately supplies power to the necessary place of the image forming apparatus 1 by using the switches 21 to 24. Each power state is described below.
[Sleep state]
In this mode, the power of the image forming apparatus 1 itself is dropped as much as possible.

  Peripheral devices of the CPU 13 can be put into a general suspend state (ACPI-S3 etc.), and only the part that can detect a job (sleep power 31) can be energized to bring the entire device into a very low power state. it can.

  Specifically, the CPU 13 stores the state of the device in the memory 15, and powers off the controller unit power 25 including itself. At this time, although the CPU 13 itself does not operate, the sleep power 31 is turned on as a hardware, and only the arrival of the job can be recognized. Then, for example, when the network reception from the LAN 9, the FAX call from the FAX apparatus 7, and the operation of the operation unit 8 are performed, the controller unit power 25 is turned on in hardware.

The CPU 13 reads out the state of the device stored in the memory 15 from the memory 15, resets it, returns to the state just before the power of the controller unit power 25 is turned off, and shifts to the standby state.
Since most of the hardware can not operate in the sleep state, it has only a function to transition to the standby state.
The job is accepted after transitioning to the standby state.

[Standby state]
The controller unit power 25 is in a state of being energized. The operation by the operator from the operation unit 8, the job via the network from the LAN 9, etc. are received.

  Since the printer unit power 28, the scanner unit power 26, and the general-purpose image processing unit power 27 are off, the CPU 13 executes a predetermined job after energizing the devices used by the switches 22 to 24. For example, the power of each device is turned on according to the job type as follows.

[Power supply status during copy job processing]
The scanner unit power 26 and the printer unit power 28 are turned on to realize the copying function as described above.
[Power supply status at the time of image transmission job processing]
Only the scanner unit power 26 is turned on, and the read image data is transmitted.
[Power supply status at the time of image storage job processing]
Only the scanner unit power 26 is turned on, and the read image data is stored.

[Power supply status at the time of image print job processing]
Only the printer unit power 28 is turned on to print various image data.
[Power supply status at the time of FAX reception printing]
The printer unit power 28 and the general-purpose image processing unit power 27 are turned on, and the received FAX image is printed after being subjected to general-purpose image processing.
[Power state during AX transfer processing]
Only the general-purpose image processing unit power 27 is turned on, and the data received by FAX is transferred after being subjected to general-purpose image processing.

[Power supply status at the time of FAX memory reception processing]
Only the general-purpose image processing unit power 27 is turned on, general-purpose image processing is performed on the data received by FAX, and the data is stored in the hard disk 14.
[Power state at the time of FAX transmission processing]
The scanner unit power 26 and the general-purpose image processing unit power 27 are turned on, and the read FAX image data is transmitted to the public network.

  By powering off the device when the job is completed, it is possible to energize only the device that is necessary only when using it, and it is possible to reduce standby power during standby.

FIG. 2A is a view showing an example of a UI screen displayed on the operation unit 8 shown in FIG.
This UI screen is a screen of the main menu, and is a screen that is first displayed after power on activation or after recovery from the sleep state in factory default settings.

  The UI screen shown in FIG. 2A corresponds to the screen initially displayed on the display unit of the operation unit 8 and can be changed by a setting / registration screen (FIG. 2F) described later. In the main menu screen, function buttons are arranged. A button 211 is selected for copying, a button 212 for faxing, a button 213 for scanning and saving, a button 214 for using a saved file, and a button 215 for performing setting or registration.

  FIG. 2B is a view showing an example of a UI screen displayed on the operation unit 8 shown in FIG. The present UI screen is a copy screen, and when the user selects the button 211, the controller 3 displays the present screen on the operation unit 8. The user makes various settings on this screen and copies.

  FIG. 2C is a view showing an example of a UI screen displayed on the operation unit 8 shown in FIG. The UI screen is a screen of a function to scan and save, and when the user selects the button 213, the controller 3 displays the screen on the operation unit 8. The user determines the storage location of the scanned document on this screen and scans the document.

  FIG. 2D is a diagram showing an example of a UI screen displayed on the operation unit 8 shown in FIG. The UI screen is a screen of a function to use the storage file, and when the user selects the button 214, the controller 3 displays the screen on the operation unit 8. The user selects a save file to be output, and outputs a document.

  FIG. 2E is a diagram showing an example of a UI screen displayed on the operation unit 8 shown in FIG. The UI screen is a fax screen, and when the user selects the button 212, the controller 3 displays the screen on the operation unit 8. The user sets the transmission destination and transmission settings, and performs fax transmission.

  FIG. 2F is a view showing an example of a UI screen displayed on the operation unit 8 shown in FIG. The UI screen is an example of a setting / registration screen, and when the user presses a setting registration button on the operation unit 8, the controller 3 displays the screen on the operation unit 8. The user can select a screen to be displayed after activation / restoration in the setting column 261, and is set to the main menu in the figure. Here, when the user selects the copy screen, the screen initially displayed after power on activation or after waking up from sleep is the copy screen of FIG. 2B. The setting field 261 is configured of, for example, a combo box 263, and a button 262 may be used to select and register one of the screens shown in FIGS. 2A to 2E first displayed after power on or after returning from sleep. It is configured to be possible. The sleep return button is a button for instructing a request for transitioning to a state in which job processing can be executed, and the power saving mode is canceled and transition to the normal mode is accepted by accepting pressing of the sleep return button. Control is started.

  FIG. 3 is a view showing the correspondence between job processing and an energization device in the image forming apparatus showing the embodiment.

  In FIG. 3, the rows show the devices that are energized and controlled in the present system, and the columns show the functions of the present system. When the user selects the copy function to execute the job, the operation of all the devices of the scanner device 2, the printer device 4, the controller 3, and the image processing unit 5 is required. Therefore, when FIG. 2B is registered as the return screen on the screen of FIG. 2F, the CPU 13 turns on / off the switches 21 to 24 of the power supply device 6 to power the device used in the copy function. The supply can be started at S404 shown in FIG. As a result, after the controller 3 shifts to the standby state, it is possible to shorten the time from when the copy job is input until the job processing is started.

  Similarly, when implementing the function of scanning and storing, the operations of the scanner device 2, the controller 3, and the image processing unit 5 are required. Therefore, when FIG. 2C is registered as the return screen on the screen of FIG. 2F, the CPU 13 turns on / off the switches 21 to 24 of the power supply device 6 to supply power to devices used in the scan function. The supply can be started at S404 shown in FIG. As a result, after the controller 3 shifts to the standby state, the time from when the scan job is input until the start of the job processing can be shortened, and the power supply to the printer device 4 is restricted. The scan job can be executed in a maintained state.

  Similarly, when implementing the function of using the storage file, operations of the printer device 4, the controller 3, and the image processing unit 5 are required. For this reason, when FIG. 2D is registered as the return screen on the screen of FIG. 2F, the CPU 13 instructs the devices used in the storage job function by turning on / off the switches 21 to 24 of the power supply device 6 Power supply can be started at S404 shown in FIG. As a result, after the controller 3 shifts to the standby state, it is possible to shorten the time from when the storage job is input until the job processing is started.

  Similarly, when implementing the facsimile function, operations of the scanner device 2, the controller 3, and the image processing unit 5 are required. In other cases, the operation of the controller 3 is required. Therefore, when FIG. 2E is registered as the return screen on the screen of FIG. 2F, the CPU 13 turns on / off the switches 21 to 24 of the power supply device 6 to power on the device used for the facsimile function. The supply can be started at S404 shown in FIG. As a result, after the controller 3 shifts to the standby state, it is possible to shorten the time from when the storage job is input until the job processing is started. Since the power supply to the printer 4 is limited, it is possible to execute the facsimile job while maintaining the power saving effect.

  Even before the job type is determined, for example, when the copy screen is selected, it is considered that the possibility of implementing the copy function is high. Therefore, in the present embodiment, when the screen of a function such as copying is set as the initial screen at the time of start-up or sleep return, control of the power supply of the device to be used is shown at FIG. Do.

  FIG. 4 is a flowchart for explaining a control method of the image forming apparatus showing the present embodiment. This example is an example of controlling the return timing of the device used in the job processing associated with the initial screen. In this flow, when executing a job by shifting from the sleep state to the standby state, in parallel with the process of the controller 3 being in standby, the job function used by the job function associated with the screen to be restored that is registered and registered. An example of control for starting power supply to the device to be connected will be described. Each step is realized by the CPU 13 executing a control program stored in the hard disk 14 or the ROM or the like. Hereinafter, an example of power control for supplying power to a device specified based on the job processing function associated with the initial screen to be displayed when transitioning the controller 3 to the standby state according to the received instruction will be described. Do. In the present embodiment, an instruction to shift job processing to an executable state indicates an example of a power-on instruction or an instruction to restore from a power saving state to a normal state (sleep return instruction).

  In the sleep state, when the user presses the sleep return button in the operation unit 8 (S401), the CPU 13 of the controller 3 performs the sleep return processing (S402) as described above. At the end of the return processing, the controller 3 determines which function processing a screen to be displayed on the operation unit 8 is registered by the user using the UI screen shown in FIG. 2F. Furthermore, in order to execute the job processing function specified in the UI screen to be displayed at the time of recovery, the controller 3 displays the initial state at the time of power recovery according to the relationship between the job processing and the power supply destination shown in FIG. It is determined which device the job that can be input from the screen requires an operation (S403).

  Here, when the CPU 13 determines that the operation of the device requiring the return operation is necessary in order to execute the job processing associated with the UI screen to be displayed at the time of the return, the CPU 13 controls the power of the device. To perform return processing (S404). As a result, job processing of the UI screen to be displayed as an initial screen on the operation unit 8 at the time of restoration is made executable.

Then, the CPU 13 shifts to the standby state (S405). When the user instructs job execution using the UI screen displayed as the initial screen on the operation unit 8 (S406), the CPU 13 determines whether the recovery processing status of the apparatus necessary for the execution job is completed. (S407).
Here, when the CPU 13 determines that the recovery processing status of the device necessary for the execution job is completed, the job processing is immediately executed (S409), and the present processing ends.

  On the other hand, if the CPU 13 determines in S407 that the device recovery process status required for the execution job has not been completed, the device used in the job processing associated with the UI screen to be displayed as the initial screen is the job Move to a processable state (S408) and proceed to S409

  As a result, after the user instructs to execute the job, normally, there is no need to perform the engine recovery process in S408. Therefore, the job process in which the user is associated with the initial screen is quickly performed without degrading the responsiveness of the image forming apparatus. Can do it.

  Second Embodiment

    Hereinafter, in the image forming apparatus shown in FIG. 1, FIG. 2, and FIG. 3, the embodiment transitions from the sleep state to the standby state and controls the power supply destination of the image forming apparatus when the user uses a function requiring authentication. The form will be described.

  FIG. 5 is a view showing an example of a UI screen displayed on the operation unit 8 shown in FIG. This example is an example of a user authentication screen of each function. This user authentication screen is a screen that is required when the use restriction for each function is implemented, such as when the copy function is permitted only to a specific authenticated user. The authentication algorithm is arbitrary. In FIG. 5, although authentication is performed with the user name 501 and the password 502, another authentication method using an IC card or a fingerprint may be used. In this embodiment, when the user selects a job processing function to be displayed on the initial screen using the UI screen shown in FIG. 5, the function setting screen based on the selected job processing function is used as the initial screen on the hard disk 14 or the like. Remember. The CPU 13 adopts a configuration in which an initial screen to be displayed is specified according to the stored job processing function. The method of specifying the initial screen is the same as in the first embodiment.

  FIG. 6 is a flow chart for explaining a control method of the image forming apparatus showing the present embodiment. The present example is a control example in which power supply to a device used in the job is started to return to a job processable state at a timing when a job determined to be usable in the user authentication process is determined. Each step is realized by the CPU 13 executing a control program stored in the hard disk 14 or the ROM or the like. Hereinafter, when the controller 3 is transitioned to the standby state, when it is determined that the job processing function selected by the user can be executed using the initial screen to be displayed, it is specified by the selected job processing function An example of power control for supplying power to a device will be described.

  When the user presses the sleep return button on the operation unit 8 (S601), as described above, the CPU 13 of the controller 3 performs a predetermined sleep return processing (S602), and shifts to the standby state.

  Since the main menu screen corresponding to the UI screen shown in FIG. 2A is displayed on the operation unit 8 at the time of return processing, the user uses the main menu screen to select a function to be used (S603). Here, the CPU 13 confirms the operation instruction from the user on the operation unit 8 and specifies the selected function. Thereafter, the CPU 13 displays an authentication screen on the operation unit 8 as the UI screen shown in FIG. 5, and determines whether the user has the authority to use the selected function (S604). In the image forming apparatus, it is assumed that the administrator or the like has registered a function that can be used in advance by the user. Therefore, the CPU 12 is configured to be able to determine based on the registered user information whether it is possible to execute the job processing function selected by the user.

Here, when the CPU 13 determines that the function selected by the user can be used, when the CPU 13 permits the use of the function, a device required for the function according to the power supply destination according to the function processing shown in FIG. Power on and perform return setting (S605). Then, while the user is setting a job, a recovery process of devices related to the selected job of the image forming apparatus is performed. Then, when the user instructs job execution using the operation unit 8, the CPU 13 confirms that the job has been input, performs job processing (S606), and ends this processing.
In this way, since the engine recovery process is performed before the user instructs job execution, the job can be processed without reducing the power saving performance and without reducing the responsiveness of the apparatus.

Third Embodiment
Hereinafter, in the image forming apparatus shown in FIGS. 1, 2 and 3, the sleep state is shifted to the standby state, and the power supply destination of the image forming apparatus is controlled using the use history of the user who uses the image forming apparatus. Embodiments will be described. It is assumed that the type of job selected immediately before the user to be authenticated is managed using the hard disk 14 or a server device (not shown). In addition, by registering the type of the job selected immediately before on the device to be user-authenticated, for example, the IC card, by scanning the IC card at the time of user authentication, it is possible to specify the type of job the user selected immediately before You may configure it.

  FIG. 7 is a flowchart illustrating a control method of the image forming apparatus according to the present embodiment. This example is a control example in which power supply to the device used in the job is started to return to a state where the job can be processed at the timing when the use history of the job selected by the user for the image forming apparatus is confirmed. Each step is realized by the CPU 13 executing a control program stored in the hard disk 14 or the ROM or the like. The control for supplying power to the device specified from the job processing function selected immediately before by the authenticated user when the controller 3 is shifted to the standby state will be described in detail below.

  When the user performs an authentication operation, the CPU 13 of the controller 3 recognizes which user is operating the image forming apparatus (S701). Note that the user authentication method is arbitrary, and authentication may be performed simultaneously with the sleep return operation using an IC card or the like, or authentication may be performed by inputting a user name and login after pressing the sleep return button.

  Then, the CPU 13 controls the switch of the power supply 6 to perform the sleep recovery process (S702), and shifts to the standby state. The CPU 13 identifies the type of job previously performed by the in-use user from the information related to the use history of the authenticated user, and determines which device of the image forming apparatus needs the operation (S703) . Then, in accordance with the power supply destination for each function processing shown in FIG. 4, the power supply of the device required for the function is turned on and recovery setting is performed (S704).

  When the user instructs job execution using the operation unit 8 (S705), the CPU 13 determines whether or not the device recovery process necessary for the job to be executed is completed (S706). Here, if the CPU 13 determines that the devices of the image forming apparatus have already been restored, the CPU 13 performs the received job processing using the operation unit 8 (S 708), and ends the present processing.

On the other hand, if the CPU 13 determines in step S706 that the device recovery process necessary for the job to be executed is not complete, the CPU 13 continues recovery processing of each device of the image forming apparatus (S707), and proceeds to step S708.
Thus, after the user instructs job execution, normally, the engine recovery process (S707) is not performed, so that the job can be processed without reducing the responsiveness of the image forming apparatus.
According to the above embodiment, power supply to the device specified by the job processing function to be executed by the user can be started in parallel with the transition of the controller to the standby state.
Further, since power supply to devices other than those required by the user can be restricted, power saving effects can be expected, and job processing requested by the user can be executed promptly after the controller shifts to the standby state.

  Each process of the present invention can also be realized by executing software (program) acquired via a network or various storage media with a processing device (CPU, processor) such as a personal computer (computer).

  The present invention is not limited to the above embodiments, and various modifications (including organic combinations of the respective embodiments) are possible based on the spirit of the present invention, which are excluded from the scope of the present invention is not.
