The controller unit 1 executes processing corresponding to the detected command.

  The notification unit 14 is formed of, for example, a light emitting diode (LED). As will be described later, the MFP according to the embodiment shifts to a power saving mode during the transmission of information such as image data, and cuts off the power supplied to a location other than the location where the information is transmitted. For this reason, the notification unit 14 performs lighting control (or flashing control) during transmission of information and transmission to the operator so that the operator does not inadvertently turn off the main power of the MFP. Notify that there is. In this example, the notification unit 14 formed by a light emitting diode (LED) is controlled to be turned on or blinking.

The RAM 9 is an example of a second storage unit and consumes less power than the HDD 8.

  In the case of the MFP according to the embodiment, an information processing program for performing transition control to a power saving mode, which will be described later, and retransmitting (retrying) image data that has failed to be transmitted, is stored in the HDD 8 as an example. The sub CPU 11 (and the main CPU 5) develops the information processing program read from the HDD 8 on the RAM 9, which is the main storage device, etc., controls the transition to the power saving mode, and retransmits the image data that has failed to be transmitted ( (Retry) etc. are controlled.

Further, the communication module 10 acquires information supplied from an external device via the network 12 and stores it in the HDD 8 or RAM 9. In this case, the communication module 10 also serves as an information acquisition unit. The scanner unit 2 and the printer unit 3 provided as the information acquisition unit are examples. For this reason, a facsimile apparatus may be provided as the information acquisition unit, or a card reader that acquires information stored in the semiconductor memory card may be provided.

  The SRM 37 process, together with the SCS 38, controls the system and manages resources. The process of the SRM 37 performs execution control in accordance with a request from an upper layer using hardware resources such as an engine such as the scanner unit 2 or the printer unit 3, memory, HDD file, and host I / O. The host I / O is a Centro I / F, a network I / F, an IEEE 1394 I / F, an RS232C I / F, or the like.

  Specifically, the SRM 37 determines whether the requested hardware resource is available (whether it is not used by another request), and if it is available, the requested hardware resource can be used. Tell the upper layer to the effect. In addition, the SRM 37 performs hardware resource usage scheduling in response to a request from an upper layer, and directly executes the request contents (for example, paper conveyance and image forming operation, memory allocation, file generation, etc. by the printer engine). .

  The process of the SCS 38 performs application management, operation unit control, system screen display, LED display, resource management, interrupt application control, and the like.

The FCS 34 process also provides APIs for registering / quoting various facsimile data managed by BKM (backup SRAM), facsimile reading, facsimile reception printing, and fusion transmission / reception.

  The process of the NCS 36 is a process for providing a service that can be commonly used for applications that require network I / O. The process of the NCS 36 distributes data received from the network side according to each protocol to each application. Further, the process of the NCS 36 mediates when data is transmitted from the application to the network side.

  The process of the OCS 35 controls the operation panel 4 serving as information transmission means between the operator and the main body control. The OCS 35 includes a part of an OCS process that acquires a touch operation (or key press) on the operation panel 4 as a key event and transmits a key event function corresponding to the acquired key to the SCS 38. The OCS 35 includes an OCS library portion in which a drawing function for drawing and outputting various screens on the operation panel 4 and a function for controlling the operation panel 4 are registered in advance in response to a request from the application 20 or the control service.

  As described above, the MFP according to the embodiment includes a plurality of applications 20 and a plurality of control services, all of which operate as processes. In each of these processes, one or a plurality of threads are generated and parallel execution is performed in units of threads. The control service provides a common service to the application 20. For this reason, these many processes perform parallel operations and parallel operations of threads, perform inter-process communication with each other and perform cooperative operations, and provide user services for image forming processing such as copying, printers, scanners, and facsimiles. It has come to offer.

  In the MFP according to the embodiment, third parties such as MFP customers and third vendors can develop and provide external applications in the application layer above the control service layer.

  In the MFP according to the embodiment, the processes of a plurality of applications 20 and the processes of a plurality of control services are operating. However, the applications 20 and the processes of the control services may each have a single configuration. Each application 20 can be added or deleted for each application.

  Next, the operation of the MFP according to the embodiment having such a configuration will be described. FIG. 3 is a flowchart showing an operation flow of the MFP that shifts to the power saving mode when the acquired information is transmitted. In the case of the example shown in FIG. 3, in step S1, for example, the scanner unit 2 scans an image. Next, in step S <b> 2, the main CPU 5 controls to store the image data acquired by scanning in the HDD 8. In this example, the acquired image data is stored in the HDD 8, but may be stored in the ROM 6, NVRAM 7, or RAM 9.

  Next, when the operator designates transmission of image data acquired by scanning, the sub CPU 11 reads out and controls the image data stored in the HDD 8 in step S3. Then, the sub CPU 11 controls communication of the communication module 10 so as to transmit the read image data to, for example, the external server device 13.

  Next, when it is time to transmit such image data, the sub CPU 11 determines in step S4 whether or not a predetermined time such as 5 seconds or 30 seconds has elapsed since the start of image data transmission. To do. The sub CPU 11 repeatedly executes step S4 until the passage of the predetermined time is detected (step S4: No). If the sub CPU 11 detects the elapse of the predetermined time in step S4 (step S4: Yes), the sub CPU 11 advances the process to step S5.

  In step S5, since a predetermined time has elapsed since the start of transmission of image data, the sub CPU 11 shifts to the power saving mode. When the sub CPU 11 shifts to the power saving mode, the sub CPU 11 controls to cut off the power supply to a portion other than the portion necessary for transmitting the image data. Specifically, a portion surrounded by a dotted line in FIG. 1 is a portion necessary for transmitting image data. For this reason, in the example shown in FIG. 1, the sub CPU 11 controls to cut off the power supplied to the scanner unit 2, printer unit 3, operation panel 4, main CPU 5, ROM 6, and NVRAM 7. As a result, the MFP is apparently stopped, but the transmission of the image data is continuously performed. Therefore, while image data with a large amount of information is being transmitted, it is possible to prevent inconvenience that power is wasted by energizing portions that are not related to transmission for a long time.

  In addition to the power saving operation, the sub CPU 11 controls the lighting of the notification unit 14 formed of, for example, an LED (blinking control may be performed) while image data is being transmitted. During the power saving mode, it is difficult for the operator to recognize whether image data is being transmitted. Therefore, by controlling the lighting of the notification unit 14 and notifying the operator that image data is being transmitted, inconveniences such as the operator accidentally disconnecting the power outlet of the MFP can be prevented.

  The sub CPU 11 determines whether or not transmission of all the image data is completed in step S6. The sub CPU 11 repeatedly executes step S6 until it is determined that transmission of all the image data has been completed (step S6: No). If the sub CPU 11 determines that the transmission of all the image data has been completed (step S6: Yes), the process of the flowchart of FIG. 3 ends. When the sub CPU 11 determines that the transmission of all the image data has been completed, the sub CPU 11 may control to cut off the power supply to the communication module 10 (and the HDD 8 and the RAM 9), and may shift to a so-called sleep mode. The MFP returns from the sleep mode when the operator performs an operation such as operating the operation panel 4.

  As is clear from the above description, the MFP according to the first embodiment shifts to the power saving mode when a predetermined time has elapsed since the start of image data transmission, and the sub CPU 11 transmits the image data. The power supply to the parts other than the necessary part is cut off. As a result, while image data with a large amount of information is being transmitted, it is possible to prevent inconvenience that power is unnecessarily consumed by energizing portions that are not related to transmission for a long time.

  In addition to the power saving operation, the sub CPU 11 controls the lighting of the notification unit 14 while transmitting image data to notify the operator that image data is being transmitted. As a result, it is possible to prevent inconveniences such as the operator accidentally unplugging the power outlet of the MFP.

  In the description of the first embodiment described above, the sub CPU 11 shifts to the power saving mode at a timing when a predetermined time has elapsed since the time of transmission. This may be shifted to the power saving mode without waiting for the elapse of a predetermined time at the timing of transmission. In this case, since it immediately shifts to the power saving mode at the time of transmission, further power saving can be achieved.

(Second Embodiment)
Next, an MFP according to the second embodiment will be described. In the MFP according to the second embodiment, the power supplied to the HDD 8 is cut off when the sub CPU 11 determines in step S6 that transmission of all image data has been completed. It is. Note that only the above point is different between the first embodiment described above and the second embodiment described below. For this reason, only the difference between the two will be described below, and a duplicate description will be omitted.

  The flowchart of FIG. 4 is a flowchart illustrating the operation flow of the MFP according to the second embodiment that shifts to the power saving mode when the acquired information is transmitted. In FIG. 4, the operations in steps S1 to S6 are the same as those in the MFP of the first embodiment described above. For details, refer to the description of steps S1 to S6 described above.

  In the flowchart of FIG. 4, when the sub CPU 11 shifts to the power saving mode and determines in step S6 that transmission of all image data has been completed (step S6: Yes), the process proceeds to step S11. In step S11, since the transmission of all the image data is completed, the sub CPU 11 controls to cut off the power supplied to the HDD 8 storing the image data for which transmission has been completed, and ends all the processes in the flowchart of FIG.

  In the case of the second embodiment, the power supplied to the HDD 8 is controlled to be cut off even when the transmission of the image data fails because communication is disabled while leaving part or all of the image data to be transmitted. To do. The image data that could not be transmitted is retransmitted by a retry described later.

  In the case of the MFP according to the second embodiment, when transmission of all image data is completed, the power supplied to the HDD 8 that is no longer needed can be reduced, and further power saving can be achieved. In addition, the same effects as those in the first embodiment described above can be obtained.

(Third embodiment)
Next, an MFP according to the third embodiment will be described. As described in the MFP of the second embodiment, the MFP according to the third embodiment tries to transmit image data again after a predetermined time when the transmission of image data fails. It has a retry function. The second embodiment described above is different from the third embodiment described below only in this respect. For this reason, only the difference between the two will be described below, and a duplicate description will be omitted.

  The flowchart in FIG. 5 is a flowchart showing the operation flow of the MFP according to the third embodiment having a retry function. In the MFP according to the third embodiment, the operation until image data is transmitted and the power supplied to the HDD 8 is cut off is the same as that of the MFP according to the second embodiment described with reference to FIG. . For details, refer to the description of the flowchart of FIG. If transmission of part or all of the image data fails and power supplied to the HDD 8 is cut off in step S11 of the flowchart of FIG. 4, the process proceeds to step S21 of the flowchart of FIG.

  In the case of the MFP according to the third embodiment, if the transmission of the image data fails, for example, a maximum of 5 times every 5 minutes, a re-transmission (retry) of the image data, and the like a predetermined number of times. Attempts to resend image data. Specifically, the sub CPU 11 of the MFP according to the third embodiment temporarily controls power to be supplied to the HDD 8 when image data transmission fails. Then, in step S21 of the flowchart of FIG. 5, the sub CPU 11 determines whether or not a predetermined time such as 5 minutes has elapsed since the power supplied to the HDD 8 is cut off, and whether or not the retry time has come. Count by counting the time information supplied from.

  The sub CPU 11 repeatedly executes the process of step S21 until it is determined that the predetermined time has elapsed (step S21: No). If the sub CPU 11 determines that the predetermined time has elapsed (step S21: Yes), the process proceeds to step S22. In step S22, the sub CPU 11 resumes the supply of power to the HDD 8 in which the image data to be transmitted is stored, and the HDD is activated. In step S23, the sub CPU 11 reads the image data from the HDD 8 again and controls the communication module 10 to transmit the read image data. As a result, for example, five minutes after the image data transmission fails, the image data is retransmitted.

  When the retransmission of the image data is started in this way, the sub CPU 11 determines whether or not the retransmission of all the image data to be transmitted has been completed in step S24. Until the re-transmission of all the image data to be transmitted is completed (step S24: No), the sub CPU 11 repeatedly executes the process of step S24. If the sub CPU 11 determines that the retransmission of all the image data to be transmitted has been completed (step S24: Yes), the sub CPU 11 advances the process to step S25.

  If the sub-CPU 11 fails to transmit the image data even though the image data has been re-transmitted, the sub CPU 11 controls the power supplied to the HDD 8 to stop, as described in steps S21 and S22. , Retry after a predetermined time. This retry is repeated up to five times until the transmission of the image data is successful. If the image data cannot be transmitted even after retrying up to 5 times, the sub CPU 11 controls the notification unit 14 to blink with a blinking pattern indicating that transmission of the image data is stopped. Alternatively, an error message indicating that transmission of image data has been stopped is displayed on the operation panel 4.

  Next, when transmission of image data is completed by performing a retry, the sub CPU 11 advances the process to step S25, cuts off the power supplied to the HDD 8, and ends the process shown in the flowchart of FIG.

  As described above, the MFP according to the third embodiment can further reduce power consumption of the MFP by supplying power to the HDD 8 when retrying (when necessary). The same effects as those of the above-described embodiments can be obtained.

(Fourth embodiment)
Next, an MFP according to the fourth embodiment will be described. As described in the above-described MFPs of the second and third embodiments, the MFP according to the fourth embodiment transmits image data to be transmitted to the HDD 8 when attempting to retransmit image data that has failed to be transmitted. The power supplied to the HDD 8 is controlled to be cut off after moving from the memory to the RAM 9. As a result, further power saving is achieved. Note that only the above points are different between the above-described embodiments and the fourth embodiment described below. For this reason, only the difference between the two will be described below, and a duplicate description will be omitted.

  The flowchart in FIG. 6 is a flowchart illustrating the operation flow of the MFP according to the fourth embodiment. In the MFP according to the fourth embodiment, the operations from the transition to the power saving mode to the transmission of image data (the operations in steps S1 to S5) are the second embodiment described with reference to FIG. This is the same as the MFP of the form. For details, refer to the description of the flowchart of FIG.

  When the transmission of the image data is started, the sub CPU 11 advances the processing to step S21 in the flowchart of FIG. 6 and determines whether or not the transmission of all or a part of the image data stored in the HDD 8 has failed. If the transmission of all the image data is successful (step S31: No), the sub CPU 11 advances the process to step S35, and controls to cut off the power supplied to the HDD 8. As a result, the MFP according to the fourth embodiment can further save power as described above.

  Next, when the transmission of the image data has failed (step S31: Yes), the sub CPU 11 advances the processing to step S32, and determines whether or not it is set to retry. As an example, in the case of the MFP according to the fourth embodiment, the operator can set whether to retry. Information indicating whether or not to retry is stored in the NVRAM 7 or the ROM 6. When the sub CPU 11 fails to transmit the image data, the sub CPU 11 makes a determination in step S32 with reference to information indicating whether or not to perform a retry stored in the NVRAM 7 or the ROM 6 or the like.

  If the sub CPU 11 determines in step S32 that no retry has been set by the operator (step S32: No), the sub CPU 11 advances the process to step S35 and controls to cut off the power supplied to the HDD 8. Thereby, as mentioned above, further power saving can be achieved. In this case, the image data is retransmitted by the retransmission operation by the operator.

  On the other hand, if it is determined in step S32 that the retry is set by the operator (step S32: Yes), the sub CPU 11 advances the process to step S33. Then, in step S33, the sub CPU 11 determines whether or not the data amount of the image data currently stored in the HDD 8 that has failed in transmission is a data amount that can be stored in the RAM 9. If it is determined that the amount of data is not storable in the RAM 9 (step S33: No), the sub CPU 11 advances the process to step S35, and once cuts off the power supplied to the HDD 8, thereby reducing power consumption. Plan. In this case, since retry is set, the sub CPU 11 performs retransmission control of image data after a predetermined time has elapsed.

  On the other hand, if it is determined that the amount of data is storable in the RAM 9 (step S33: Yes), the sub CPU 11 advances the process to step S34, and the image data stored in the HDD 8 (= transmission failed). Image data) is moved to and stored in the RAM 9. Then, the sub CPU 11 advances the process to step S35, and controls to cut off the power supplied to the HDD 8 in which the movement of the image data is completed. Note that after the image data is transferred to the RAM 9, the sub CPU 11 reads the image data from the RAM 9 and retransmits (retry) it.

  The power consumption of the HDD 8 is larger than that of the RAM 9. For this reason, the image data to be retried is moved to the RAM 9 and then the supply of power to the HDD 8 is controlled to be cut off, so that further power saving of the MFP can be achieved.

  Each above-mentioned embodiment is shown as an example and is not intending limiting the range of the present invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. For example, in the above description of the embodiment, the present invention is applied to an MFP.
