  The printer unit 130 forms an image on a recording sheet. The printer unit 130 employs a method of forming a latent image on a photoconductor with a laser or an LED line head, or directly ejects ink onto a recording sheet. A well-known hardware configuration such as an ink jet method employing the method can be used. The control unit 110 causes the printer unit 130 to perform predetermined paper output based on an instruction from the operation panel unit 150, the personal computers 200, 200 ′, and 200 ″, or an external device 300 such as a mobile phone or a digital camera.

In the initial screen display of the scan mode on the operation panel unit 150, the storage destination of the image data read by the scanner unit 140 can be selected from “USB memory”, “PC folder”, and “e-mail”. Here, the USB memory is an example of the “external storage medium” in the present invention.

  FIG. 3 is a diagram showing an example of an initial screen display in the external storage medium print mode of the image processing apparatus (multifunction machine) according to the embodiment of the present invention. In the initial screen display of the print mode on the operation panel unit 150, printing from an external storage medium such as “USB memory” can be designated, and it is also used as a standby screen for authentication printing using a password.

  FIG. 4 is a diagram showing an example of an initial screen display in the facsimile transmission mode of the image processing apparatus (multifunction machine) according to the embodiment of the present invention. In the initial screen display of the facsimile transmission mode on the operation panel unit 150, the user is prompted to specify the facsimile transmission destination “destination”. Further, by selecting tabs such as “basic settings”, “functions”, “applications”, detailed settings can be made.

  FIG. 5 is a diagram showing an initial screen display example in the copy mode of the image processing apparatus (multifunction machine) according to the embodiment of the present invention. In the initial screen display of the copy mode on the operation panel unit 150, the user is prompted to input the number of copies. Further, by selecting tabs such as “basic setting”, “function”, “application 1”, and “application 2”, detailed settings can be made.

  Next, the sleep mode in the image processing apparatus of the present invention will be described. The sleep mode of the present invention is a mode in which the power consumption is reduced from the normal standby state, and can be considered as a power saving mode, a power saving mode, and the like.

The sleep mode in the image processing apparatus (multifunction peripheral 100) of the present invention is set for each device of the printer unit 130, the scanner unit 140, and the operation panel unit 150. Each sleep mode can be defined, for example, as follows. Needless to say, such a definition can have various modes.
Printer unit 130 sleep mode: power-off of fixing unit, power-off of motor control unit, etc.
Sleep mode of the scanner unit 140: power supply to the document illumination lamp control unit, the image sensor control unit, the carriage motor control unit, etc.
Sleep mode of operation panel unit 150: backlight off, etc.
Sleep mode of the facsimile unit 102: energization of all circuits except the facsimile reception circuit is turned off.

  Next, the default mode of the multifunction machine 100 will be described. As described above, the MFP 100 has various modes such as “scan mode”, “copy mode”, “facsimile transmission mode”, and “external storage medium print mode”, but each user mainly uses them. The mode to perform is relatively fixed. That is, there are many cases in which a certain user uses the multifunction peripheral 100 mainly at the copier and another user mainly uses the multifunction peripheral as a facsimile machine. Therefore, if the concept of returning to (or shifting to) the “default mode” is adopted, the convenience of the MFP 100 is enhanced. FIG. 6 is a diagram for explaining the concept of the default mode in the image processing apparatus (multifunction machine) according to the embodiment of the present invention.

  The “default mode” is a mode that is restored when the MFP 100 is turned on or has not been operated for a predetermined time after using a certain mode. The user can select “scan mode”, “copy mode”, “facsimile transmission mode”. In this mode, one of the “external storage medium print modes” can be set and registered. FIG. 6 shows an image in which the multi-function device 100 returns to the default mode after a predetermined time elapses from the mode selected by the user.

  It should be noted that the present invention can be applied to both image processing apparatuses provided with image processing apparatuses that do not include such a “default mode” (or image processing apparatuses that do not actively use the default mode).

  FIG. 7 is a diagram illustrating a sequence of the image processing apparatus that enters the sleep mode after shifting to the default mode, and FIG. 8 is a diagram illustrating a sequence of the image processing apparatus that enters the sleep mode from each mode.

  Looking at FIG. 7 in chronological order, if any operation is not performed for a predetermined time from any mode selected by the user, the mode is shifted to the default mode. This default mode is any one of “scan mode”, “copy mode”, “facsimile transmission mode”, and “external storage medium print mode” set by the user.

  When a predetermined time elapses without any operation on the multi-function device 100 or print data input, the mode shifts to the sleep mode. The sleep state is canceled by the operation of the operation panel unit 150 by the user or the input from the personal computers 200, 200 ', 200' '.

  Next, look at FIG. 8 in order of time passage. When there is no operation for a predetermined time from any one of the “scan mode”, “copy mode”, “facsimile transmission mode”, and “external storage medium print mode” selected by the user, the multi-function device 100 operates in the sleep mode. Will be moved to. The sleep state is canceled by the operation of the operation panel unit 150 by the user or the input from the personal computers 200, 200 ', 200' '.

  The present invention relates to cancellation of the sleep mode in the multi-function device 100 having the above-described configuration, and particularly relates to a wake-up manner of the multi-function device 100 triggered by detection of a manuscript on a manuscript table or ADF. Here, both of the document open / close detection on the document table and the document set detection on the ADF can be performed by a conventionally known method. In addition, document open / close detection on the document table and document set detection on the ADF are hereinafter defined as “document detection”. In addition, a known technique can be used for a method of determining a user operation that triggers cancellation of the sleep mode, such as a key operation or data reception.

  FIG. 9 is a flowchart of the original detection return processing in the image processing apparatus (multifunction peripheral) according to the embodiment of the present invention. In FIG. 9, when the original detection return process is started in step S101, the process proceeds to step S102. In step S102, it is determined whether the mode immediately before the MFP 100 enters the sleep mode is the scan mode. Here, the “mode immediately before entering the sleep mode” is shown in FIGS. Further, in this step, it may be determined whether the “default mode set by the user” and the “operation mode last selected by the user before shifting to the sleep mode” are the scan modes.

  If the determination result in step S102 is YES, the process proceeds to step S103, and if the determination result in step S102 is NO, the process proceeds to step S108.

  In step S103, the scanner unit 140 starts to recover from the power saving state (the state in the sleep mode). Then, it progresses to step S104 and the return from the power saving state of the operation panel part 150 is started. In step S105, the operation panel unit 150 displays that the scanner unit 140 is warming up.

FIG. 10 is a diagram showing a screen display example in the operation panel unit 150 indicating that data is transferred from the scanner unit 140 to the USB memory. In step S109, an initial screen display in the scan mode is displayed on the operation panel unit 150. An example of the initial screen display in the scan mode is as shown in FIG.

  In subsequent step S133, the original detection return processing is terminated.

  In step S110, it is determined whether or not the mode immediately before the MFP 100 enters the sleep mode is the copy mode. Further, in this step, it may be determined whether the “default mode set by the user” and the “operation mode last selected by the user before shifting to the sleep mode” are the copy mode.

  When the result of determination in step S110 is YES, the process proceeds to step S111, and when the result of determination in step S110 is NO, the process proceeds to step S116.

  In step S111, the printer unit 130 and the scanner unit 140 start to recover from the power saving state (sleep mode state). Subsequently, in step S112, the operation panel unit 150 starts to return from the power saving state. Next, in step S113, a message indicating that the printer unit 130 and the scanner unit 140 are warming up is displayed on the operation panel unit 150.

Step S114: It is determined whether the printer unit 130 and the scanner unit 140 have been restored from the power saving state.
If the determination result of step S114 is NO, step S114 is looped, and if the determination result of step S114 is YES, the process proceeds to step S115.

  In step S115, an initial screen for copy mode is displayed on operation panel unit 150. The initial screen of such a copy mode is as shown in FIG.

  In subsequent step S133, the original detection return processing is terminated.

  Next, step S116 and subsequent steps that proceed when the determination result in step S110 is NO will be described.

  In step S116, it is determined whether or not the mode immediately before the MFP 100 enters the sleep mode is the facsimile transmission mode. In this step, it may be determined whether or not the “default mode set by the user” and the “operation mode last selected by the user before shifting to the sleep mode” are the facsimile transmission modes. .

  When the result of determination in step S116 is YES, the process proceeds to step S117, and when the result of determination in step S116 is NO, the process proceeds to step S122.

  In step S117, the scanner unit 140 and the facsimile unit 120 are started to recover from the power saving state. Subsequently, in step S118, a return process from the power saving state of the operation panel unit 150 is started. In step S119, the operation panel unit 150 displays that the scanner unit 140 and the facsimile unit 120 are warming up.

  In step S120, it is determined whether the scanner unit 140 and the facsimile unit 120 have been restored from the power saving state.

  When the determination result in step S120 is NO, step S120 is looped. When the determination result in step S120 is YES, the process proceeds to step S121, and the initial screen of the facsimile transmission mode is displayed on the operation panel unit 150. An initial screen of such a facsimile transmission mode is as shown in FIG.

  In subsequent step S133, the original detection return processing is terminated.

  Next, step S122 that proceeds when it is determined NO in step S116 will be described. In steps after step 122, it is determined that the MFP 100 was in the “external storage medium print mode” immediately before the MFP 100 enters the sleep mode. That is, it is assumed that the multifunction device 100 is in the external storage medium print mode. Although the operations around the document table and the operation of inserting the USB memory are duplicated as user operations, in the following steps, the insertion of the USB memory is temporarily detected, and this operation is performed from the sleep mode. To help return. Here, a well-known technique is used as a method for the MFP 100 to detect insertion of a USB memory or the like.

  In step S122, it is determined whether or not insertion of a USB memory into a connector unit (not shown) of the multifunction peripheral 100100 is detected.

  When the result of determination in step S122 is YES, the process proceeds to step S123, and when the result of determination in step S122 is NO, the process proceeds to step S131.

  In step S123, it is determined whether there is print data to be printed on the USB memory. A well-known technique for detecting the presence / absence of print data in the USB memory is used.

  When the determination result in step S123 is YES, the process proceeds to step S124, and when the determination result in step S123 is NO, the process proceeds to step S129.

  In step S124, the printer unit 130 starts to recover from the power saving state. In a succeeding step S125, a return process from the power saving state of the operation panel unit 150 is started. Next, in step S126, the operation panel unit 150 displays that the printer unit 130 is warming up.

  In the next step S127, it is determined whether or not the printer unit 130 has been restored from power saving. When the determination result of step S127 is NO, step S127 is looped. When the determination result of step S127 is YES, the process proceeds to step S128.

  In step S128, data is transferred from the USB memory to the printer unit 130, and a message screen indicating that the printer unit 130 executes printing is displayed on the operation panel unit 150. FIG. 11 is a diagram showing a screen display example in the operation panel unit 150 indicating that data is transferred from the USB memory to the printer unit 130 and printing is executed by the printer unit 130.

  In subsequent step S133, the original detection return processing is terminated.

  In step S129 that proceeds when the determination result in step S123 is NO, a process for returning the operation panel unit 150 from the power saving state is started. In the subsequent step S130, the operation panel unit 150 displays a message screen indicating that there is no data to be printed in the USB memory by pop-up display.
