The network image reading apparatus 10 includes a reading unit 11, a temporary storage unit 13, a condition receiving unit 15, a start receiving unit 16, an interface unit 17 (shown as “I / F” in the figure), and a detecting unit 19. A transfer destination display unit 21, a transfer destination reception unit 23, a transfer unit 25, a determination unit 27, and a notification unit 29.

  In FIG. 2, the configuration of parts not related to the essence of the present invention is omitted.

  Each component of the network image reading apparatus 10 includes an arbitrary computer CPU, memory, a program for realizing the components shown in the figure loaded in the memory, a storage unit such as a hard disk for storing the program, and a network connection. It is realized by any combination of hardware and software centering on the interface. It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus. Each drawing described below shows a functional unit block, not a hardware unit configuration.

  The reading unit 11 reads a document and acquires image data. The reading unit 11 is, for example, a scanner. The temporary storage unit 13 temporarily stores the image data acquired by the reading unit 11. In the present embodiment, the image data temporarily stored in the temporary storage unit 13 is transferred to the personal computer 7 and then deleted.

  The condition receiving unit 15 receives various conditions when the reading unit 11 reads a document, for example, settings such as resolution and density. The start accepting unit 16 accepts an instruction to start reading by the reading unit 11 after the user sets a document on the network image reading apparatus 10, or an instruction to start retransmission when a transfer error occurs. For example, when the user presses a start button (not shown), the start receiving unit 16 receives a start instruction.

  The interface unit 17 is an interface unit that connects the network image reading apparatus 10 to the personal computer 7 via the network 1. The network image reading apparatus 10 logs in to the network 1 via the interface unit 17 and refers to and accesses the shared folder 5 in the storage device 3 of the personal computer 7.

  The detection unit 19 detects the shared folder 5 in the storage device 3 of the personal computer 7 via the network 1. The transfer destination display unit 21 displays the shared folder 5 of the storage device 3 of the personal computer 7 detected by the detection unit 19 as a transfer destination candidate. Here, the transfer destination candidates can be shown by, for example, a tree diagram or a table showing the folder structure of the shared folder 5 in the storage device 3 of each personal computer 7.

  The transfer destination receiving unit 23 receives the shared folder designated as the transfer destination of the image data from among the shared folders 5 of the storage device 3 of the personal computer 7 detected by the detection unit 19. Further, the transfer destination receiving unit 23 receives an instruction as to whether or not to resend to an alternative transfer destination when a transfer error occurs.

  The transfer unit 25 transfers the image data stored in the temporary storage unit 13 to the transfer destination received by the transfer destination receiving unit 23 via the interface unit 17. The determination unit 27 determines whether or not the transfer of the image data has been normally completed by the transfer unit 25. The notification unit 29 notifies the determination result of the determination unit 27. The notification unit 29 is, for example, a display unit, a voice output unit, and an e-mail transmission unit.

  FIG. 3 is a flowchart showing an example of the operation of the network image reading apparatus 10 of FIG.

  First, the condition receiving unit 15 receives a reading condition (S11). Subsequently, the detection unit 19 detects the shared folder 5 that can be currently shared via the network 1 and displays it on the transfer destination display unit 21 (S13). FIG. 4 is a diagram illustrating an example of a transfer destination designation screen displayed on the transfer destination display unit 21. On the transfer destination designation screen 31, a shared folder list 33 is displayed, and a list of folders that can be currently shared is displayed. Returning to FIG. 3, the transfer destination receiving unit 23 receives the transfer destination selected by the user (S15). The transfer destination selected by the user is presented to the user by reverse display on the transfer destination designation screen 31 of FIG.

  Until this point, the user sets the document. Subsequently, the start receiving unit 16 receives an instruction to start reading when the start button is pressed (YES in S17). Here, when the transfer destination receiving unit 23 receives the designation of the alternative transfer destination in a step described later, a retransmission flag is set. When a start instruction is accepted in step S17 (YES in S17), the transfer unit 25 determines whether or not a retransmission flag is set (S18). If the retransmission flag is not set (NO in S18), the first transfer is accepted, so the start instruction accepted by the start accepting unit 16 is an instruction to start reading, and the reading unit 11 reads the document (S19). Store in the temporary storage unit 13 (S21).

  The transfer unit 25 transfers the image data stored in the temporary storage unit 13 to the transfer destination received by the transfer destination receiving unit 23 via the interface unit 17 (S23). Subsequently, the determination unit 27 determines whether or not the transfer of the image data is normally completed by the transfer unit 25 (S25). When the transfer is completed normally (YES in S25), the transfer unit 25 retransmits the image data. The flag is reset (S29), and the process ends. Here, the image data stored in the temporary storage unit 13 may be deleted. On the other hand, if the transfer is not normally completed due to some reason, for example, cancellation of sharing of the transfer destination shared folder 5, logoff of the personal computer 7, deterioration or disconnection of the communication state of the network 1 (NO in S 25). ), The notification unit 29 notifies that (S27).

  FIG. 5 is a diagram illustrating an example of a transfer error notification screen displayed on the notification unit 29 of the network image reading apparatus 10. The transfer error notification screen 41 notifies the user that the transfer has failed, and has an alternative transfer destination designation button 43 for designating an alternative transfer destination, and an end button 45 for interrupting the transfer.

  Returning to FIG. 3, when the transfer destination accepting unit 23 accepts the pressing of the alternative transfer destination designation button 43 in FIG. 5, it is retransmitted to the alternative transfer destination (YES in S <b> 28), and the transfer unit 25 sets the retransmission flag. (S30), the process returns to step S13. Subsequently, the detection unit 19 detects the shared folder 5 that can be currently shared via the network 1 and displays it on the transfer destination display unit 21 (S13). Subsequently, the transfer destination receiving unit 23 receives the transfer destination selected by the user (S15). When the start button is pressed, the start receiving unit 16 receives a start instruction (YES in S17).

  Subsequently, the transfer unit 25 determines whether or not the retransmission flag is set (S18). When the retransmission flag is set (YES in S18), the start instruction received by the start receiving unit 16 is an instruction to start retransmission, bypassing steps S19 and S21 for document reading, and the transfer unit 25 temporarily The image data stored in the storage unit 13 is transferred again to the alternative transfer destination received by the transfer destination receiving unit 23 via the interface unit 17 (S23). As described above, when the transfer error occurs, the image data stored in the temporary storage unit 13 can be retransmitted to the alternative transfer destination without reading the document again.

  On the other hand, in step S28, when the transfer destination accepting unit 23 accepts pressing of the end button 45 in FIG. 5 (NO in S28), the transmission of the image data is interrupted, and the transfer unit 25 resets the retransmission flag (S29). This process is terminated.

As described above, according to the present embodiment, when transfer of image data to the transfer destination is not normally completed, it can be transferred again to the alternative transfer destination, so it is necessary to read again even when a transfer error occurs. There is provided an easy-to-use network image reading apparatus that can efficiently retransmit.
(Second embodiment)
FIG. 6 is a schematic block diagram showing a main configuration of the network image reading apparatus 10 according to the present embodiment. The network image reading apparatus 10 in FIG. 6 is different in that it includes a transfer destination determination unit 51 and a table storage unit 53 in addition to the configuration of the network image reading apparatus 10 in FIG.

  The table storage unit 53 stores a priority table 53a in which the transfer destination priority is registered in advance. FIG. 7 is a diagram illustrating an example of the priority order table 53a. In the priority order table 53a, the priority order of the shared folder 5 in the storage device 3 is registered. For example, a server or the like that is always connected to the network 1 can be registered at a higher priority of the transfer destination.

  Returning to FIG. 6, the transfer destination determination unit 51 determines the shared folder 5 as the transfer destination according to the priority order registered in the priority order table 53a.

  In the present embodiment, when the image data is automatically retransmitted to the alternative transfer destination by the transfer unit 25, a notification unit that notifies the user that the image data has been retransmitted to the alternative transfer destination may be provided. For example, “The specified folder does not exist, so it has been transferred to the following folder as an alternative transfer destination.” Is displayed on the display unit.

According to the network image reading apparatus 10 configured in this way, when the transfer fails, the alternative transfer destination can be registered in advance, so that it can be automatically transferred to the alternative transfer destination when a transfer error occurs. Since the storage capacity of the temporary storage unit 13 of the image reading apparatus 10 is less occupied by image data waiting for transfer, the capacity of the temporary storage unit 13 of the network image reading apparatus 10 can be reduced.
(Third embodiment)
FIG. 8 is a schematic block diagram showing a main configuration of the network image reading apparatus 10 according to the present embodiment. The network image reading apparatus 10 in FIG. 8 is different in that it includes a timer setting reception unit 61 and a timer 63 in addition to the configuration of the network image reading apparatus 10 in FIG.

  The timer setting accepting unit 61 accepts designation of a timing for retransmission when the transfer unit 25 does not complete transfer normally. Here, the retransmission timing is, for example, a retransmission time or a retransmission retry time interval. For example, when a transfer error occurs due to logoff or the like, the time when the next login is likely to be made, for example, the morning of the next day, can be designated as the retransmission time. Alternatively, when a transfer error occurs due to deterioration of the communication state or the like, it can be specified to retry at intervals of several minutes.

  The timer 63 counts the timing received by the timer setting reception unit 61 and notifies the transfer unit 25 that the time is up.

  The operation of the network image reading apparatus 10 configured as described above will be described below with reference to FIG. FIG. 9 is a flowchart illustrating an example of an operation at the time of retransmission in the case of a transfer error of the network image reading apparatus 10.

  In Step S25 of the flowchart of FIG. 3, when the determination unit 27 determines that the transfer has not been completed normally (NO in S25), the notification unit 29 notifies that (S41). The timer setting reception unit 61 receives a retransmission timing at the time of a transfer error (S43), and starts the timer 63 (S45). The timing of retransmission may be set in advance, or when the notification unit 29 notifies a transfer error, the user may be prompted to set and accept an input.

  It is monitored whether or not the timer 63 has timed up (S47). When the time has expired (YES in S47), the process returns to step S23 in FIG. 3 and is automatically retransmitted.

  According to the network image reading apparatus 10 configured in this way, image data that has failed to be transferred can be automatically retransmitted at a delayed timing without being read again, so that convenience is increased.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and it goes without saying that those skilled in the art can modify the above-described embodiments within the scope of the present invention.

  For example, in the above embodiment, the user designates an alternative transfer destination from the list of the shared folders 5 detected by the detection unit 19 at the time of a transfer error, but the detection unit 19 has at least one shared folder at the time of the transfer error. 5 may be detected and the user may be confirmed as an alternative transfer destination. At this time, the detection unit 19 can detect, for example, another shared folder 5 in the same hierarchy as the shared folder 5 in which a transfer error has occurred or a shared folder 5 in the hierarchy one level above. If there are a plurality of detected shared folders 5, the transfer destinations are determined in accordance with a predetermined priority order, for example, name order, creation date order, log-in order to the network 1, descending order, ascending order, etc. It can also be determined. Or it can also be set as the structure which transfers to an alternative transfer destination automatically. In this case, it is preferable to have a recording unit for recording the transfer destination.

  Further, in the network image reading apparatus 10 of FIG. 6, when determining the transfer destination, the transfer destination is determined according to the priorities registered in advance in the priority table 53a. However, the present invention is not limited to this. For example, a condition registration unit (not shown) that preliminarily registers conditions for determining the priority order of the transfer destination and a determination unit that determines the priority order of the transfer destination according to the condition can be included. Here, the conditions for determining the priority order of the transfer destination include, for example, the name order of the storage device 3 and the shared folder 5 of the transfer destination, the order of creation date and time, the order of login to the network 1, and the descending order and ascending order thereof. is there.

  When the determination unit 27 determines that the transfer has not been completed normally, the transfer destination receiving unit 23 can receive the shared folder 5 of the transfer destination as an alternative transfer destination according to the priority order. The alternative transfer destination may be automatically designated according to the priority order, or the transfer destination may be presented according to the priority order and the designation of the transfer destination from the user may be accepted.

  According to this configuration, since the priority order of the transfer destinations can be determined according to a predetermined condition, it is possible to specify an appropriate alternative transfer destination and improve the reliability of the system.

  In the above embodiment, the detection unit 19 is configured to detect the shared folder 5 of the storage device 3 of the personal computer 7 via the network 1, but the detection unit 19 further detects the shared folder 5 detected. A folder attribute acquisition unit that acquires an overwrite prohibition attribute and a password authentication attribute can be included.

  According to this configuration, it is possible to present the attribute of the shared folder 5 detected by the detection unit 19 as a transfer destination candidate after confirming that overwriting is not prohibited and that password authentication is not required. Therefore, since a more appropriate folder can be presented as a transfer destination candidate, the occurrence of transfer errors can be further reduced.

  Moreover, in the said embodiment, although it was set as the structure which provided the transfer destination display part 21 as a presentation part which presents the shared folder 5 detected by the detection part 19, other than this, a presentation part is memory which can be shared. A printing unit that outputs a list of the shared folder 5 of the apparatus 3 may be provided.

  In the above embodiment, the image data is retransmitted when the transfer destination list is displayed on the transfer destination display unit 21 before reading the original by the reading unit 11 in step S13 of FIG. When the alternative transfer destination to be displayed is displayed on the transfer destination display unit 21, the detection unit 19 detects the shared folder 5 that can be currently shared via the network 1. However, the present invention is not limited to this. For example, the detection unit 19 may be configured to detect the shared folder 5 that can be shared via the network 1 periodically or at a predetermined time and store it in the storage unit as a transfer destination. When the transfer destination list is displayed before the reading of the document by the reading unit 11, the transfer destination display unit 21 displays the transfer destination stored in the storage unit.

  According to this configuration, when the image data is transferred, it is possible to reduce the time required for the detection of the shared folder 5 by the detection unit 19, and thus it is possible to reduce the time required for the transfer of the image data.
