In the case of an imaging apparatus, captured image information and audio information are transmission targets. If it is an electric appliance, the information on the state of the electric appliance itself is a transmission target. If it is a sensor, the information which can be sensed by each sensor will be transmitted. In the case of an automobile, information such as a travel distance and a position is a transmission target. In addition, any one of them is not limited to the one connected to the user terminal 200, and a plurality of types of device devices may be connected to the user terminal 200.

<Configuration of image reading apparatus>
FIG. 1 is a schematic diagram of an image reading apparatus 100 according to the present embodiment. The image reading apparatus 100 is an apparatus that transports one or a plurality of transport media S stacked on the mounting table 1 one by one through the path RT in the apparatus, reads the image, and discharges the image onto the discharge tray 2. The reading medium S to be read is, for example, a sheet of OA paper, a check, a check, a card or the like, and may be a thick sheet or a thin sheet. Examples of the cards include an insurance card, a driver's license, and a credit card. The transport medium S also includes a booklet such as a passport.

  A first transport unit 10 is provided as a feeding mechanism that feeds the transport medium S along the route RT. In the case of this embodiment, the first transport unit 10 includes a feed roller 11 and a separation roller 12 disposed to face the feed roller 11, and sequentially transports the transport medium S on the mounting table 1 one by one in the transport direction D1. Transport. A driving force is transmitted to the feed roller 11 from the driving unit 3 such as a motor through the transmission unit 5 and is rotationally driven in the direction of the arrow in the drawing (the forward direction in which the transport medium S is transported along the path RT). The transmission unit 5 is, for example, an electromagnetic clutch, and interrupts the driving force from the driving unit 3 to the feed roller 11. For example, in this embodiment, the transmission unit 5 that connects the drive unit 3 and the feed roller 11 is in a state in which the driving force is transmitted in a normal state, and interrupts the driving force when the transport medium S is reversely fed. When the transmission of the driving force is interrupted by the transmission unit 5, the feed roller 11 is in a freely rotatable state. In addition, such a transmission part 5 does not need to be provided when driving the feed roller 11 only in one direction.

  The separation roller 12 disposed to face the feed roller 11 is a roller for separating the transport medium S one by one, and is in pressure contact with the feed roller 11 with a constant pressure. In order to secure this pressure contact state, the separation roller 12 is provided so as to be swingable and is urged to the feed roller 11. The separation roller 12 is driven to rotate in the direction indicated by the solid line arrow (the direction opposite to the forward direction of the feed roller 11) when the driving force is transmitted from the driving unit 3 via the torque limiter 12a.

  Since the driving force transmission is restricted by the torque limiter 12a, the separation roller 12 rotates in a direction (indicated by a broken arrow) along with the feed roller 11 when contacting the feed roller 11. As a result, when a plurality of transport media S are transported to the pressure contact portion between the feed roller 11 and the separation roller 12, two or more transport media S are blocked so that they are not transported downstream except one. .

  In the present embodiment, the separation roller 12 and the feed roller 11 constitute a separation mechanism. However, such a separation mechanism is not necessarily provided, and the conveyance medium S is sequentially fed to the path RT one by one. Any feeding mechanism may be used. In the case where a separation mechanism is provided, instead of the configuration of the separation roller 121, a separation pad that applies a frictional force to the transport medium S is brought into pressure contact with the feed roller 11 so as to have the same separation work. May be.

  The second transport unit 20 as a transport mechanism on the downstream side in the transport direction of the first transport unit 10 includes a drive roller 21 and a driven roller 22 driven by the drive roller 21 and has been transported from the first transport unit 10. The transported medium S is transported downstream. Driving force is transmitted to the driving roller 21 from the driving unit 4 such as a motor, and the driving roller 21 is rotationally driven in the direction of the arrow in the figure. The driven roller 22 is brought into pressure contact with the driving roller 21 at a constant pressure, and rotates with the driving roller 21. The driven roller 22 may be configured to be biased against the driving roller 21 by a biasing unit (not shown) such as a spring.

  The third transport unit 30 located on the downstream side in the transport direction with respect to the second transport unit 20 includes a driving roller 31 and a driven roller 32 that judos the drive roller 31 and is transported from the second transport unit 20. The transport medium S is transported to the discharge tray 2. That is, the third transport unit 30 functions as a discharge mechanism. Driving force is transmitted to the driving roller 31 from the driving unit 4 such as a motor, and the driving roller 31 is rotationally driven in the direction of the arrow in the figure. The driven roller 32 is brought into pressure contact with the driving roller 31 at a constant pressure, and is driven by the driving roller 31. The driven roller 32 may be configured to be biased against the driving roller 31 by a biasing unit (not shown) such as a spring.

  Here, in the image reading apparatus 100 according to the present embodiment, the image reading unit 70 disposed between the second transport unit 20 and the third transport unit 30 reads an image. The three transport unit 30 transports the transport medium S at a constant speed. By always setting the transport speed to be equal to or higher than the transport speed of the first transport unit 10, it is possible to reliably avoid a situation in which the subsequent transport medium S catches up with the preceding transport medium S. For example, in this embodiment, speed control is performed so that the transport speed of the transport medium S by the second transport section 20 and the third transport section 30 is faster than the transport speed of the transport medium S by the first transport section 10. did.

  Even when the transport speed of the transport medium S by the second transport section 20 and the third transport section 30 and the transport speed of the transport medium S by the first transport section 10 are the same, the drive section 3 is controlled. It is also possible to form a minimum interval between the preceding transport medium S and the subsequent transport medium S by intermittently shifting the feeding start timing of the subsequent transport medium S.

  When the double feed detection sensor 40 disposed between the first transport unit 10 and the second transport unit 20 is in contact with transport media S such as paper due to static electricity or the like, and passes through the first transport unit 10 ( In other words, this is an example of a detection sensor (a sensor for detecting the behavior and state of the sheet) for detecting this in the case of a double feed state in which the sheets are conveyed in an overlapping manner. Various sensors can be used as the double feed detection sensor 40, but in the case of the present embodiment, it is an ultrasonic sensor, and includes an ultrasonic transmission unit 41 and a reception unit 42, and is a conveyance medium such as paper. Double feed is detected based on the principle that the attenuation amount of the ultrasonic wave passing through the transport medium S is different between the case where S is transported one by one and the case where S is transported one by one.

  The medium detection sensor 50 arranged on the downstream side in the conveyance direction with respect to the double feed detection sensor 40 is located on the upstream side of the second conveyance unit 20 and on the upstream side arranged on the downstream side of the first conveyance unit 10. This is an example of a detection sensor (a sensor for detecting the behavior and state of a sheet). The position of the transport medium S transported by the first transport unit 10, specifically, the position of the transport medium S at the detection position of the medium detection sensor 50. Detect whether the end has reached or passed. As the medium detection sensor 50, various sensors can be used. In the case of this embodiment, the medium detection sensor 50 is an optical sensor, and includes a light emitting unit 51 and a light receiving unit 52, and receives light when the transport medium S reaches or passes therethrough. The transport medium S is detected based on the principle that the intensity (the amount of received light) changes.

  In the case of this embodiment, when the leading edge of the transport medium S is detected by the medium detection sensor 50, the above medium is used so that the transport medium S reaches a position where the double feed detection sensor 40 can detect double feed. The detection sensor 50 is provided on the downstream side in the vicinity of the double feed detection sensor 40. The medium detection sensor 50 is not limited to the optical sensor described above. For example, a sensor (image sensor or the like) that can detect the end of the transport medium S may be used, or a lever-type sensor that protrudes into the path RT. It may be a sensor.

  The medium detection sensor 60 different from the medium detection sensor 50 is an example of a downstream detection sensor disposed upstream of the image reading unit 70 and downstream of the second transport unit 20. The position of the transport medium S transported by the unit 20 is detected. Various media detection sensors 60 can be used. In the case of the present embodiment, the medium detection sensor 60 is an optical sensor similar to the medium detection sensor 50, and includes a light emitting unit 61 and a light receiving unit 62. The transport medium S is detected based on the principle that the received light intensity (received light amount) changes due to arrival or passage. In the present embodiment, the medium detection sensors 50 and 60 are disposed on the upstream side and the downstream side in the transport direction of the second transport unit 20, respectively, but only one of them may be used.

  The image reading unit 70 on the downstream side of the medium detection sensor 60 is, for example, optically scanned, converted into an electric signal and read as image data, and internally includes a light source such as an LED, an image sensor, and a lens array. Etc. In the present embodiment, one image reading unit 70 is disposed on each side of the path RT, and reads the front and back surfaces of the transport medium S. However, only one side of the route RT may be arranged to read only one side of the transport medium S. Further, in the present embodiment, the image reading unit 70 is configured to be opposed to both sides of the route RT. However, for example, the image reading unit 70 may be arranged with an interval in the direction of the route RT.

  The control unit 8 will be described with reference to FIG. FIG. 2 is a block diagram of the control unit 8 of A showing the hardware configuration of the image reading apparatus 100 according to the embodiment.

  The control unit 8 includes a CPU 81, a storage unit 82, an operation unit 83, a communication unit 84, an actuator 85, an interface unit 86, an image memory 89, and a form processing unit 90. The CPU 81 controls the entire image reading apparatus 100 by executing a program stored in the storage unit 82. The storage unit 82 includes, for example, a RAM, a ROM, and the like. The operation unit 83 includes, for example, a switch, a touch panel, and the like, and accepts an operation from the operator.

  The communication unit 84 is an interface that performs information communication with an external device. When a PC (user terminal) is assumed as an external device, examples of the communication unit 84 include a USB interface and a SCSI interface. In addition to such a wired communication interface, the communication unit 84 may be a wireless communication interface, and may include both wired communication and wireless communication interfaces.

  The interface unit 86 is an I / O interface that inputs and outputs data with the actuator 85 and the sensor 87. The actuator 85 includes the drive unit 3, the drive unit 4, the transmission unit 5, and the like. The sensor 87 includes a double feed detection sensor 40, medium detection sensors 50 and 60, an image reading unit 70, and the like. The image memory 89 stores image data read by the sensor 87. The form processing unit 90 performs optical character recognition processing from the image data stored in the image memory 89, recognizes the type of form, and adds information to the image data.

  Here, a basic operation of the image reading apparatus 100 will be described. For example, when receiving an image reading start instruction from the user terminal 200 to which the image reading apparatus 100 is connected, the control unit 8 starts driving the first to third transport units 10 to 30. The transport medium S loaded on the mounting table 1 is transported one by one from the transport medium S positioned at the bottom.

  In the middle of the conveyance, the conveyance medium S is determined by the double-feed detection sensor 40 to determine whether or not there is a double-feed, and if it is determined that there is no double-feed, the conveyance is continued. If it is determined that there is a double feed, the transport is stopped or the capture of the subsequent transport medium S by the first transport unit 10 is stopped, and the transport medium S in the double feed state is discharged as it is. It may be.

  The control unit 8 starts reading an image by the image reading unit 70 of the transport medium S transported by the second transport unit 20 at a timing based on the detection result of the medium detection sensor 60, and the read image is stored in the image memory. 89, optical character recognition processing is performed from the stored image data, the form type is recognized, and information is added to the image data. Thereafter, the image data is sequentially transmitted to the user terminal 200. The transport medium S from which the image has been read is discharged to the discharge tray 2 by the third transport unit 30, and the image reading process for the transport medium S is completed.

<Configuration of user terminal>
FIG. 3 is a block diagram illustrating a hardware configuration example of a computer applicable to the user terminal 200. The CPU 41 controls the entire computer using computer programs and data stored in the ROM 42 and RAM 43. The ROM 42 stores setting data for the computer, a boot program, and the like. CPU81 performs each processing mentioned later as what the user terminal 200 performs.

  The RAM 43 has an area for temporarily storing computer programs and data loaded from an HDD (Hard Disk Drive) 44, data received from the outside via the interface 47, and the like. Further, the RAM 43 has a work area used when the CPU 41 executes various processes. That is, the RAM 43 can provide various areas as appropriate.

  The HDD 44 stores computer programs and data for causing the CPU 41 to execute various processes performed by an OS (operating system) and a device to which the present computer is applied. The computer program includes a computer program for causing the CPU 41 to execute each process described later as what the user terminal 200 performs. Computer programs and data stored in the HDD 44 are appropriately loaded into the RAM 43 under the control of the CPU 41 and are processed by the CPU 41. The HDD 44 also records permission settings (permitted domain, access token, etc.) that permit cross-domain communication.

  The input device 45 includes a keyboard, a mouse, and the like. An operator of the computer can input various instructions to the CPU 41 by operating the input device 45. The display device 46 is configured by a CRT, a liquid crystal screen, or the like, and can display a processing result by the CPU 41 using an image, text, or the like. The interface 47 is composed of various interfaces. For example, a network interface for connecting the computer to a network and a device interface for connecting the image reading apparatus 100 to the computer are included. A bus 48 connects the above-described units. In the present embodiment, for ease of explanation, the user terminal 200 will be described as a computer having the configuration shown in FIG. 4, but the configuration of the computer is not limited to such a configuration.

  As shown in FIG. 4, the user terminal 200 is operated by a user and includes a browser (Web browser) 201, a ScanServer 202, and a driver 205. A user can use a Web application (Web application service providing system 300 or Web storage system 400) via the browser 201 in the user terminal 200. An extended function program (for example, add-in, add-on, extension, plug-in, etc.) can be added to the Web application by the user. The browser 201 includes an extended function program 301. When the user adds the extended function program 301, buttons (for example, 902, 903, and 904 in FIG. 9A) are arranged in the browser 201. When the user selects this button, the extended function program 301 uses the ScanServer 202. Then, the image reading apparatus 100 is controlled, and the read image is stored in the Web storage system 400. Specific processing of the extended function program 301 will be described later.

  The scan server 202 includes a web server unit 203 and an image reading device operation unit 204. The browser 201 communicates with a Web application (Web application service providing system 300, Web storage system 400). The Scan Server 202 is a program (Web server program) that operates in the user terminal 200 on which the browser 201 that communicates with the Web application (Web application service providing system 300, Web storage system 400) operates. The Web server unit 203 of the ScanServer 202 avoids communication blocking by a firewall (not shown), and operates as a Web server that can resolve the name from a browser on any user terminal, so that it waits with the host name localhost in the user terminal 200. May be performed.

  The scan server 202 uses an image reading apparatus 100 connected to the user terminal 200 to perform an image reading process or the like (image reading apparatus operation unit 204), and a Web in a domain different from the Web system that is a request transmission source. An endpoint (Web server unit 203) that communicates with the system is provided. In response to a request to the Web server unit 203, the image reading device operation unit 204 can be instructed to operate the image reading device 100. The image reading device operation unit 204 operates the image reading device 100 connected to the user terminal 200. The driver 205 is software for controlling the image reading apparatus 100.

  In this embodiment, the ScanServer 202 belongs to the domain C, and the Web application service providing system 300 belongs to the domain A, and therefore belongs to different domains. Therefore, when the Web application of the Web application service providing system 300 that operates on the browser 201 in the user terminal 200 tries to communicate with the Web server unit 203 of the ScanServer 202, a cross-domain request is made.

  Accordingly, since the Web application of the Web application service providing system 300 that operates on the browser 201 becomes a cross-domain request when communicating with the Scan Server 202, it tries to transmit a request (HTTP message transmission) according to the CORS standard specification. The HTTP message includes a request / response by HTTPS communication.

  Here, with reference to FIG. 5 and FIG. 6, a process for permitting a cross-domain request and enabling cross-domain communication will be specifically described.

<Processing of browser 201>
FIG. 5 is a flowchart showing the processing of the browser 201. When the user operating the user terminal 200 is a user of the web application service providing system 300, the user accesses the web application service providing system 300 from the browser 201 in the user terminal 200. The browser 201 accesses the domain (domain A) of the web application service providing system 300 (S5001).

  The browser 201 determines whether it is request transmission (HTTP message transmission) to a different domain (for example, the scan server 202 domain (domain C)) (S5002). If the request is not transmitted to a different domain (NO in S5002), the process is repeated.

  In the case of request transmission to a different domain (ScanServer 202 domain (domain C)) (YES in S5002), the browser 201 in the user terminal 200 displays the domain (domain) of the Web application service providing system 300 in the Origin header in the request. A) is added, and a request transmission (HTTP message transmission) according to the CORS specification is performed to the ScanServer 202 (S5003). However, the request to the ScanServer 202 may be not only HTTP but also WebSocket or another protocol.

  The browser 201 determines whether a normal response has been received from the ScanServer 202 (S5004). When the scan server 202 permits the domain (domain A) of the Web application service providing system 300, a normal response is received, and when the domain is not permitted, an error response is received.

  When the browser 201 (the Web application of the Web application service providing system 300 operating on the browser 201) receives a normal response from the Scan Server 202 (YES in S5004), the browser 201 can communicate with the Scan Server 202 (S5005). That is, cross-domain communication (communication between domain A and domain C) is possible. When the browser 201 (the Web application of the Web application service providing system 300 that runs on the browser 201) receives an error response from the Scan Server 202 (NO in S5004), the browser 201 cannot communicate with the Scan Server 202.

<Processing of Scan Server 202>
FIG. 6 is a flowchart showing the process of the ScanServer 202. The started ScanServer 202 (S6001) determines whether a request (HTTP message) according to CORS has been received (S6002). If not received (NO in S6002), the process is repeated.

  When a request according to CORS is received (YES in S6002), the request source (browser 201) domain (domain A) is acquired from the Origin header in the request (S6003). It is determined whether the acquired domain is registered as a permitted domain (permitted or not) (S6004). If registered (YES in S6004), a normal response is transmitted to the request source (browser 201) domain (domain A) (S6005).

  If the permitted domain is not registered in the ScanServer 202 (NO in S6004), the ScanServer 202 determines whether the domain included in the Origin header can be registered in the permitted domain (S6006). Judgment of whether or not registration is possible, for example, by registering in advance the number of permitted domains that can be registered, if the number registered at that time is less than the number that can be registered, registration is possible, if it is more than the number that can be registered Impossible. In addition, a domain that cannot be permitted is registered in advance (for example, a black list). If the domain included in the Origin header cannot be permitted, registration is impossible, and registration is possible otherwise. In addition, a domain that can be permitted is registered in advance (for example, white list), and if the domain included in the Origin header can be permitted, registration is possible, otherwise registration is impossible.

  In addition, the setting of the permitted domain is not necessary for every request, and can be omitted if it is registered in advance. By determining whether or not registration is possible in S6006, display of unnecessary confirmation messages to the user can be reduced. If registration is not possible (NO in S6006), an error response is transmitted to the request source (browser 201) domain (domain A) as an operation in which access by CORS is prohibited (S6010).

  When registration is possible (YES in S6006), a permission confirmation message for CORS setting is displayed on the user terminal 200 (S6007). The Scan Server 202 determines whether a request from the Web application service providing system 300 is permitted by the user (S6008). If not permitted (NO in S6008), the process proceeds to S6010.

  If permitted (YES in S6008), the domain (domain A) is set and registered as a permitted domain (S6009), and the process proceeds to S6005.

  Note that the processing of S6006 to S6009 may be omitted, and if not registered in the permitted domain (NO in S6004), an error response may be transmitted (S6010). The received request may be a process of omitting the processes of S6004 and S6006 and displaying a permission confirmation message for CORS setting on the user terminal 200 (S6007). Further, the process of whether or not the acquired domain is a permitted domain (S6004) may be omitted, and a normal response may be transmitted (S6005).

<Acquisition of information including image reading processing result>
When the Web storage system 400 can be accessed with authentication information (for example, an access token) such as OAuth 2.0, which is a conventional authentication protocol, the ScanServer 202 displays an image reading processing result (read image data). The access token of the Web storage system 400 is required when transmitting information including the URL to the Web storage system 400 (domain B). Therefore, the Web application of the Web application service providing system 300 that operates on the browser 201 in the user terminal 200 acquires and stores the access token of the Web storage system 400 via the ScanServer 202 before starting the image reading process.

  FIG. 7 is a sequence diagram illustrating a functional configuration example of the system according to the embodiment. The user 1000 instructs an authentication start operation via the browser 201 (S10010). The browser 201 transmits an authentication screen request to the Web storage service 400 (S10011). The Web storage service 400 transmits an authentication screen response to the browser 201 (S10012).

  The user 1000 instructs an authentication operation via the browser 201 (S10020). The browser 201 transmits authentication information and an authorization screen request to the Web storage service 400 (S10021). The Web storage service 400 transmits an authorization screen response to the browser 201 (S10022).

  The user 1000 instructs an authorization operation via the browser 201 (S10030). The browser 201 transmits authorization information and an authorization code acquisition request to the Web storage service 400 (S10031). The Web storage service 400 transmits an authorization code and a redirect to the browser 201 (S10032). The browser 201 transmits an access token acquisition request to the ScanServer 202 (S10033). The Scan Server 202 transmits an access token acquisition request to the Web storage service 400 (S10034). The Web storage service 400 transmits an access token response to the ScanServer 202 (S10035). The Scan Server 202 transmits an access token response to the browser 201 (S10036). The browser 201 stores the received access token. The access token may be stored in the ScanServer 202.

  The user instructs an image reading process (scan start operation) via the browser 201 (S10050). The instruction includes information on scan settings (for example, storage destination, resolution, monochrome / color selection, reading size, file format, etc.). For example, when a document button is selected from a plurality of buttons (document button, receipt button, photo button, etc.) displayed on the browser 201, the designated scan setting (monochrome, 300 dpi, A4 size, duplex) is used. Instructs image reading. Note that the web application of the web application service providing system 300 that runs on the browser 201 can be freely customized by the user.

  The Web application of the Web application service providing system 300 that operates on the browser 201 in the user terminal 200 sends a request (starting request related to image reading) to the ScanServer 202, the access token acquired in S10035, the scan setting information, and the image reading process. ) Is transmitted (S10051). The scan server 202 holds the access token acquired in step S10035. In order to occupy the image reading apparatus 100, the Scan Server 202 may have a lock function for fixing the use source by issuing a unique connection ID (identification information) to the request source.

  The scan server 202 transmits scan setting information and a request to start the image reading process to the driver 205, and the driver 205 transmits scan request information and a request to start the image reading process to the image reading apparatus 100. (S10052).

  As described with reference to FIG. 1, the image reading apparatus 100 starts driving the first to third transport units 10 to 30. The transport medium S loaded on the mounting table 1 is transported one by one from the transport medium S positioned at the bottom. The control unit 8 starts reading an image by the image reading unit 70 based on the received scan setting information for the transport medium S transported by the second transport unit 20 at a timing based on the detection result of the medium detection sensor 60. To do. The read image is stored in the image memory 89, optical character recognition processing is performed from the stored image data, the form type is recognized, and information on the form type is added to the image data. Thereafter, the acquired image data is sequentially transmitted to the driver 205. The driver 205 transmits the acquired image data to the Scan Server 202 (S10053). The transport medium S from which the image has been read is discharged to the discharge tray 2 by the third transport unit 30, and the image reading process for the transport medium S is completed.

  The Scan Server 202 is a request for information including an access token specified by the Web application of the Web application service providing system 300 that runs on the browser 201 in the user terminal 200 and held in the Scan Server 202, and an image reading processing result (image data). Is transmitted to the Web storage service 400 which is the storage destination (S10054). The information including the image reading processing result is, for example, information that associates the user with the image data, OCR information of the image data, time, and the like. The Web storage service 400 transmits a response to the ScanServer 202 (S10055).

  Thereafter, the Web application of the Web application service providing system 300 that operates on the browser 201 in the user terminal 200 transmits information including the image reading processing result and a request for the transmission result to the ScanServer 202 as appropriate (S10056), and the ScanServer 202 sends a response. It transmits to the browser 201 (S10057).

  Accordingly, the Web application of the Web application service providing system 300 (domain A) that operates on the browser 201 in the user terminal 200 only performs image reading processing and image reading to the Web storage system 400 (domain B) through communication with the ScanServer 202. Information including the processing result (read image data) can be transmitted.

  If the Web storage system 400 does not request an access token when the Scan Server 202 transmits an image reading process result or information, the access token acquisition process (S10010 to S10036) in FIG. 7 can be omitted.

  According to the present embodiment, when performing communication for instructing image reading processing to the Scan Server 202, the Web application of the Web application service providing system 300 operating on the browser 201 is authenticated by the Web storage system 400 that is a different domain. By giving information (for example, an access token) to the Scan Server 202, the Scan Server 202 can transmit information including the image reading processing result to the Web storage system 400.

  The request transmission from the ScanServer 202 to the Web storage system 400 is not from the browser 201 but communication from a general application, and thus does not correspond to cross domain access. Accordingly, the Web application of the Web application service providing system 300 that operates on the browser 201 directly communicates with the Web storage system 400 that is a different domain from the Web application service providing system 300 via the ScanServer 202 in the user terminal 200. Instead, information including the image reading processing result (image data) acquired from the image reading apparatus 100 can be transmitted to the Web storage system 400.

  Up to this point, it has been assumed that domain A and domain B are different, but they may be the same. For example, there is a case where URLs for receiving information including a Web application and an image reading processing result are prepared in the same domain.

  Here, with reference to FIGS. 8 and 9, processing for sharing data between windows executed by the Web application even when Web Storage is invalid will be described in detail. In the following, description will be made using storage location information for storing scanned images as an example of data. However, the present invention is not limited to this, and is executed by a Web application such as login management information (user name, password), access token, and the like. Any information that can be shared between windows is acceptable.

<Processing of Extended Function Program 301>
FIG. 8 is a flowchart showing processing of the extended function program 301. The process in FIG. 8 is executed every time data is received from the browser 201 between S10011 and S10036 in FIG. FIG. 9A and FIG. 9B are diagrams showing an example of a window screen displayed on the browser 201.

  When the function expansion program 301 receives data from the browser 201 (S1101), it transmits a data storage request to the ScanServer 202 (transmission means) (S1102). The data is, for example, storage location information 902 (for example, http://www.Foo.) Shown in FIG. The scan server 202 stores the received data in its own memory. When storing, the ScanServer 202 may store the identification information (for example, process ID) for identifying the Web browser 201 and the data in association with each other. If the identification information and the data are stored in association with each other, only the web application executed by the web browser associated with the data can read and write the data. For example, after a Web application that operates on the Web browser (A) makes a save request to the ScanServer 202, a Web application that operates on a Web browser (B) different from the Web browser (A) reads data from the ScanServer 202. ScanServer 202 can return an error.

  The function expansion program 301 determines whether the window executed by the Web application of the Web application service providing system 300 has been changed to a window executed by another Web application (Web application of the Web storage system 400) (S1103). . The determination as to whether the process has been changed can be made based on whether the process (process name, process ID) has been changed.

  A specific example of changing to a window executed by another Web application will be described with reference to FIG. FIG. 9A shows a window screen 901 of the Web application of the Web application service providing system 300 that operates on the browser 201. When the user selects the confirm button 903 on the window screen 901, the screen transitions to the window screen 911 of the Web application of the Web storage system 400 shown in FIG. 9B.

  When it is determined that the Web application has been changed (the window screen has been changed) (YES in S1103), the function expansion program 301 determines whether the original Web application has been changed (changed to the original window screen) ( S1104). If it is determined that the function has been changed (YES in S1104), the function expansion program 301, which is also a reading unit, issues a data read request to the Scan Server 202 (S1105), and receives data from the Scan Server 202 (S1106). Therefore, even when the Web application being executed (HOGEHOGE Web application) is changed to another Web application (Foo Web application), the executed Web application (HOGEHOGE Web application) is refreshed due to the limitation of the Web application. The storage destination information 902 can be acquired without being performed.

  Note that the function expansion program 301 may make a data read request to the Scan Server 202 when it is determined that the Web application has been changed (the window screen has been changed). Further, when it is determined that the Web application has been changed (the window screen has been changed), the function expansion program 301 may make a data transmission request to the Scan Server 202 so as to transmit data to the changed Web application. In that case, the ScanServer 202 transmits data to the changed Web application.

  Further, the Scan Server 202 keeps data while it is not overwritten during execution of the Web application. However, when the Scan Server 202 is not accessed from the Web application for a certain period of time, it may be automatically deleted. Moreover, you may erase | eliminate after progress for a fixed time.

  According to the present embodiment, an extended function program added to a Web application stores data in the ScanServer 202, so that even when Web Storage is invalid, data between windows executed by the Web application can be shared. It becomes.
