FIG. 1 illustrates a configuration of a multifunction peripheral M according to an example of an information processing apparatus.
The multi-function device M of this example operates a hypervisor (virtualization processing unit) 20 on hardware that is a physical component of a computer. Under the virtualization processing by the hypervisor 20, each function can be performed. Each of the first OS 30 and the second OS 40 for realizing an execution environment of software for executing such processing is configured to operate as a virtual environment (virtual OS).

Further, the MFP M of this example includes a network I / F 10 that is a physical interface for communicating with external devices such as a file server Sa, a mail server Sb, and a user terminal T via a network. A data transfer unit 50 used for data transfer between the first OS 30 and the second OS 40 is provided.
The data delivery unit 50 of this example is configured using a storage device such as an HDD (Hard Disk Drive), and the first OS 30 and the second OS 40 can access each other (that is, data can be read and written). Shared memory.

A real-time OS places importance on executing processing in real time and is an OS that implements a function for that purpose. Since the response time of processing is required to be within a certain range, the required processing time is predicted. And a mechanism for completing within a target time even when a plurality of processing requests occur simultaneously.
A general-purpose OS is an OS that focuses on maintaining compatibility by virtualizing and abstracting software in multiple layers, thereby reducing hardware-dependent programming, and processing response time is a real-time OS. Slow compared to

The first OS 30 provided by the general-purpose OS is provided with functional units such as a communication processing unit 32 that performs communication processing with an external device, and a processing control unit 31 that controls processing in the first OS 30.

The operation of the processing control unit 31 of the first OS 30 will be described more specifically.
The processing control unit 31 determines whether the data received by the communication processing unit 32 is data that needs to be transferred to the second OS 40. Then, in the case of data for which processing is completed by the functional unit on the first OS 30 side, it is determined that there is no need to transfer it to the second OS 40, and the data is output to the corresponding functional unit in the first OS 30. On the other hand, in the case of data that needs to be processed by the functional unit on the second OS 40 side, it is determined that the data needs to be transferred to the second OS 40, and the data transfer unit for transfer to the second OS 40 The data is output to 50 and stored. That is, when the data is unnecessary for device control by the device control unit such as the image reading processing unit 42 or the image output processing unit 43 on the second OS 40 side, the data is not output to the data delivery unit 50 and is necessary for device control. If it is data, it is output to the data delivery unit 50.

  Further, when the data to be processed by the functional unit on the first OS 30 side is stored in the data delivery unit 50 (stored from the second OS 40 side), the processing control unit 31 stores the data in the data delivery unit The data is read from 50 and output to the corresponding functional unit to execute processing. If the data to be transmitted to the external device is stored in the data delivery unit 50 (stored from the second OS 40 side), the processing control unit 31 reads the data from the data delivery unit 50 and performs communication. It outputs to the process part 32 and performs a transmission process.

Read out and output to the corresponding functional unit to execute the process.

  Further, the process control unit 41 determines whether or not the data obtained as a result of the device control process by the device control unit is data that needs to be transferred to the first OS 30. Then, in the case of data for which processing is completed by the functional unit on the second OS 40 side, it is determined that it is not necessary to pass the data to the first OS 30, and the data is output to the corresponding functional unit in the second OS 40. A process is executed (for example, a copy function is realized by executing an image forming process using image data obtained by the image reading process). On the other hand, in the case of data that needs to be processed by the functional unit on the first OS 30 side or data to be transmitted to an external device, it is determined that it needs to be transferred to the first OS 30 and is transferred to the first OS 30. The data delivery unit 50 outputs and stores the data.

First, an operation related to the print function will be described.
When the operator of the user terminal T selects an electronic document or the like to instruct printing, print instruction data is transmitted from the user terminal T to the multi-function peripheral M using a communication protocol such as LPD (Line Printer Daemon). And received by the communication processing unit 32 via the network I / F 10 and the hypervisor 20.
The communication processing unit 32 interprets the print instruction data according to the LPD protocol, extracts the data part and the control command, and passes them to the processing control unit 31.

  The processing control unit 31 determines whether it is necessary to transfer the data portion and control command received from the communication processing unit 32 to the second OS 40. Since these data are targets of processing by the image output processing unit 43, it is determined that the data needs to be transferred to the second OS 40 and is output to the data transfer unit 50. In this example, the data received from the communication processing unit 32 is not output to the data delivery unit 50 as it is, but a control command (for example, an instruction for the number of pages, an instruction for double-sided printing, two pages on one sheet) Output image data is generated by performing an interpretation process of the instruction to include, and the like, and the generated output image data is output to the data delivery unit 50.

When confirming that the output image data to be processed by the image output processing unit 43 is stored in the data delivery unit 50, the processing control unit 41 reads the output image data from the data delivery unit 50 and performs image output processing. To the unit 43.

Next, an operation related to a function of transferring an image of a scan (image reading) result will be described.
When the operator of the multi-function peripheral M sets a sheet to be read on the image reading device and instructs image reading, the image reading device executes image reading under the control of the image reading processing unit 42, and as a result Read image data is generated.
Here, it is assumed that the file server Sa is designated (or preset) by the operator as the transfer destination of the read image data.

  The processing control unit 41 determines that the read image data needs to be transferred to the first OS 30 according to the designation of the transfer destination of the read image data, and the read image data is transferred to the designated transfer destination (this example). Then, the data is output to the data delivery unit 50 together with the transmission instruction data addressed to the file server Sa).

When confirming that the read image data and the transmission instruction data are stored in the data delivery unit 50, the processing control unit 31 reads the read image data and the transmission instruction data from the data delivery unit 50 and outputs them to the communication processing unit 32. .
The communication processing unit 32 executes the transmission process of the read image data received from the processing control unit 31 according to the transmission instruction data received from the processing control unit 31 using a communication protocol such as FTP (File Transfer Protocol).
Thereby, the read image data is transmitted to the file server Sa via the hypervisor 20 and the network I / F 10 and stored in the file server Sa.

Next, an operation related to the function of storing data in a confidential box using electronic mail will be described.
Here, the confidential box is a function for holding data to be processed (for example, read image data obtained by scanning or the like) for subsequent processing (for example, printing, facsimile transmission, mail transmission, etc.). It is. In this example, it is assumed that a confidential box is provided in the data delivery unit 50.

When an e-mail including a control command for storing a mail data portion in a confidential box is transmitted from the mail server Sb to the multi-function peripheral M using a communication protocol such as POP3 (Post Office Protocol 3), the network I / F10 and the hypervisor 20 are received by the communication processing unit 32 of the first OS 30.
The communication processing unit 32 interprets the electronic mail according to the POP3 protocol, extracts the data part and the control command, and passes them to the processing control unit 31.
When the processing control unit 31 receives the data part and the control command from the communication processing unit 32 and analyzes the control command to confirm that the confidential box is locked, the processing control unit 31 stores the data part in the confidential box in the data delivery unit 50.

Next, an operation related to the function of transferring data in the confidential box will be described.
It is assumed that the transfer target data stored as a transfer target in the confidential box is set with a time for executing the transfer process and a transfer destination.
The processing control unit 31 performs communication processing on the transfer target data stored in the confidential box in the data delivery unit 50 together with transmission instruction data addressed to the set transfer destination according to the arrival of the transfer processing time. To the unit 32.
The communication processing unit 32 executes the transmission processing of the transfer target data received from the processing control unit 31 according to the transmission instruction data received from the processing control unit 31.
Thereby, the transfer target data in the confidential box is transmitted to the external device via the hypervisor 20 and the network I / F 10.

As described above, in the MFP M of the present example, the functional units (such as the image reading processing unit 42 and the image output processing unit 43) for controlling devices are provided on the second OS 40 side provided by the real-time OS. Another functional unit (communication processing unit 31 or the like) is provided on the first OS 30 side provided by the general-purpose OS, and data is transferred between the first OS 30 and the second OS 40 to / from the data transfer unit 50 (data This is realized by writing and reading).
For this reason, in the second OS 40 (real-time OS), the burden due to processing other than the control of the device where real-time property is important is suppressed as much as possible, and the occurrence of an abnormality in the control of the device is suppressed.

  The multi-function device M described so far is merely an example, and the number and type of OSs to be installed, functions to be installed in each OS, and the like are arbitrary. That is, for example, a plurality of second OSs 40 provided by a real-time OS may be prepared, and the OS that is the execution environment of the processing related to the control may be different for each control target device.

FIG. 2 shows a first extension example of the multifunction peripheral M according to an example of the information processing apparatus.
The MFP M of this example has a configuration in which a data conversion processing unit 33 is provided on the first OS 30 side provided by the general-purpose OS in addition to the configuration of the MFP M illustrated in FIG. The description of the same components as those in FIG. 1 is omitted.

With reference to FIG. 2, an operation related to a function of transferring an image of a scan (image reading) result in a designated data format will be described.
When the operator of the multi-function peripheral M sets a sheet to be read on the image reading device and instructs image reading, the image reading device executes image reading under the control of the image reading processing unit 42, and as a result Read image data is generated.
Here, the file server Sa is designated (or preset) by the operator as the transfer destination of the read image data, and PDF (Portable Document Format) is designated (or preset) by the operator as the data format of the read image data. It is assumed that

  The processing control unit 41 determines that the read image data needs to be transferred to the first OS 30 according to the designation of the transfer destination of the read image data, and the read image data is transferred to the designated transfer destination (this example). Then, the data is output to the data delivery unit 50 together with the transmission instruction data addressed to the file server Sa) and the conversion instruction data instructing conversion to the designated data format.

  When the processing control unit 31 confirms that the read image data, the transmission instruction data, and the conversion instruction data are stored in the data delivery unit 50, the process control unit 31 reads the read image data, the transmission instruction data, and the conversion instruction data from the data delivery unit 50. . Then, before outputting the read image data and the transmission instruction data to the communication processing unit 32 to execute the transmission process, the read image data and the data format information are output to the data conversion processing unit 33 to execute the data conversion process.

The data conversion processing unit 33 executes processing for converting the read image data received from the processing control unit 31 into a designated data format (PDF in this example) in accordance with the conversion instruction data received from the processing control unit 31. The read image data after the format conversion is returned to the processing control unit 31.
The processing control unit 31 outputs the read image data after the data format conversion received from the data conversion processing unit 33 to the communication processing unit 32 together with the transmission instruction data.
The communication processing unit 32 executes transmission processing of the read image data after conversion of the data format received from the processing control unit 31 according to the transmission instruction data received from the processing control unit 31.
Accordingly, the read image data is transmitted to the file server Sa via the hypervisor 20 and the network I / F 10 after the data format is converted, and stored in the file server Sa.

  As described above, in the MFP M of this example, the increase in processing load on the second OS 40 (real-time OS) side is suppressed by providing the data format conversion processing on the first OS 30 side provided by the general-purpose OS. is doing. Here, in this example, the data format of the data obtained as a result of device control in the second OS 40 is converted in the first OS 30, but the data format of data given for device control in the second OS 40 is changed. Conversion may be performed in the first OS 30. The generation of the output image data based on the print instruction data described with reference to FIG. 1 is an example of the latter conversion.

FIG. 3 shows a second extension example of the multifunction peripheral M according to an example of the information processing apparatus.
The MFP M of this example has a configuration in which an ID reading processing unit 43 and an ID transmission processing unit 44 are provided on the second OS 40 side provided by the real-time OS in addition to the configuration of the MFP M illustrated in FIG. Yes. The description of the same components as those in FIG. 1 is omitted.

With reference to FIG. 3, an operation related to a function of transmitting an ID (identification information) related to an operator of the multifunction peripheral M will be described.
Here, in this example, in order to perform user authentication before the operator uses the scan function or the copy function, an ID recording medium such as an IC card in which the ID related to the operator is recorded is set in the ID reader. Suppose that it is required to do.

When the operator of the multi-function device M sets the ID recording medium in the ID reading device, the identification information is read from the ID recording medium under the control of the ID reading processing unit 43 and transferred to the processing control unit 41.
When receiving the identification information read by the ID reader, the processing control unit 41 controls the identification information to be transmitted to an external device (in this example, an authentication server) set in advance as a transmission destination. At this time, control is performed so that the data is not output to the data delivery unit 50 and transmitted to the external device via the first OS 30, but is output to the ID transmission processing unit 44 and directly transmitted to the external device.
The ID transmission processing unit 44 executes processing for transmitting the identification information received from the processing control unit 31 to the authentication server.
Thereby, the identification information is transmitted to the authentication server via the hypervisor 20 and the network I / F 10, and user authentication is executed. The identification information may be used for purposes other than user authentication. For example, when the history of the usage status of the multi-function peripheral M is accumulated for each user, or the user is charged according to the usage status. You may make it use for a case etc.

  As described above, in the MFP M of this example, the identification information transmission process is provided on the second OS 40 side provided by the real-time OS, thereby suppressing an increase in the processing load of the entire apparatus. Note that, for example, even when the read image data obtained by the image reading device has a relatively small amount of data to be transmitted to the external device, such as a barcode image, the external device does not pass through the first OS 30. You may comprise so that it may transmit directly to.
