When a second request is received from the host device, a request processing unit that transmits image data obtained by the image reading process to the host device, and a time-out period elapses after a predetermined time has elapsed since the first request was received. When the request processing unit has previously received a request other than the second request, the request processing unit includes a timeout time management unit that extends the timeout time. The timeout time management unit sets a longer timeout time in a predetermined daytime period, and sets a shorter timeout time in a predetermined nighttime period.

In addition, the image reading apparatus according to the present invention receives a request issued by the host apparatus, starts the image reading process when receiving the first request from the host apparatus, and before the time-out period elapses after receiving the first request. When a second request is received from the host device, a request processing unit that transmits image data obtained by the image reading process to the host device, and a time-out period elapses after a predetermined time has elapsed since the first request was received. When the request processing unit has previously received a request other than the second request, the request processing unit includes a timeout time management unit that extends the timeout time. In the case of the continuous reading process , the request processing unit starts the image reading process every time the first request is received from the host apparatus, and receives the second request from the host apparatus after the image reading process for one or a plurality of documents. Image data of one or more originals obtained by the image reading process is transmitted to the host device. Then, in the case of continuous reading processing, the timeout time management unit sets a timeout time between the first request and the next first request or second request that is longer than the normal timeout time.

In addition, the image reading apparatus according to the present invention receives a request issued by the host apparatus, starts the image reading process when receiving the first request from the host apparatus, and before the time-out period elapses after receiving the first request. When a second request is received from the host device, a request processing unit that transmits image data obtained by the image reading process to the host device, and a time-out period elapses after a predetermined time has elapsed since the first request was received. When the request processing unit has previously received a request other than the second request, the request processing unit includes a timeout time management unit that extends the timeout time. The time-out time management unit sets the time-out time longer when a document is placed on the automatic paper feeder.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a communication system including an image reading apparatus 1 according to Embodiment 1 of the present invention. In the communication system shown in FIG. 1, an image forming apparatus 1 and one or a plurality of host devices 2 are connected to a network 3.

  The host device 2 is a device that supplies a request to the image reading device 1 via the network 3 and operates the image reading device 1 in accordance with the request. For example, a personal computer is used as the host device 2. The host device 2 includes a driver 2a that generates a request for the image reading device 1 and transmits the request using a network interface (not shown).

  The network 3 is a computer network such as a LAN (Local Area Network).

  FIG. 2 is a block diagram showing a configuration of the image reading apparatus 1 in FIG. The image reading apparatus 1 illustrated in FIG. 2 includes a scanner 11, a network interface 12, a storage device 13, and a computer 14.

  The scanner 11 is an internal processing device that optically reads a document image from a document and generates image data of the document image.

  The network interface 12 is an electric circuit that is connected to the network 3 and performs data communication with other devices (here, the host device 2) connected to the network 3.

  The storage device 13 is a device for storing data and computer programs. As the storage device 13, a hard disk drive, a nonvolatile memory, or the like is used. The storage device 13 stores a control program 21, user data 22, and history data 23.

  The control program 21 is a computer program for realizing a request processing unit 31 and a timeout time management unit 32 described later.

  The user data 22 is data including, for a registered user, a user ID, authority of the user (administrator user, general user, etc.) and a department ID of a department to which the user belongs.

  The history data 23 is data including a reception history of a request for operating the scanner 11.

  The computer 14 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., loads a program into the RAM, and executes it by the CPU. Thereby, various processing units are realized. In the first embodiment, a request processing unit 31 and a timeout time management unit 32 are realized.

  The request processing unit 31 is a processing unit that receives a request for the scanner 11 via the network interface 12 and operates the scanner 11 in accordance with the request. In particular, when the request processing unit 31 receives a first request from the host device 2, the request processing unit 31 starts an image reading process. When the request processing unit 31 receives a second request from the host device 2 before the timeout time elapses after the first request is received, the image is processed. The image data obtained by the reading process is transmitted to the host device 2.

  Further, when receiving the request, the request processing unit 31 adds a record regarding the request to the history data 23. The record includes a request type, a reception date and time, a user ID included in the request, and address information (IP address, MAC address, etc.) of the host device 2 that transmitted the request.

  The timeout time management unit 32 is a processing unit that manages the above-described timeout time. The time-out time management unit 32 receives a request other than the second request (inquiry about the mechanical state of the scanner 11 or the job execution status) after the predetermined time has elapsed since the first request was received and before the time-out time elapses. When the request processing unit 31 receives another first request or the like, the timeout time is extended. At that time, the timeout time is extended by a predetermined ratio or a predetermined time.

  In the first embodiment, the timeout time management unit 32 extends the timeout time only once for one second request.

  Next, the operation of the image reading apparatus 1 will be described.

  The driver 2a of the host apparatus 2 transmits a request to the image reading apparatus 1 using a protocol such as SOAP (Simple Object Access Protocol). The driver 2a of the host device 2 transmits a first request for starting the image reading process, and then transmits a second request for transmitting the image data obtained by the image reading process. Receive.

  On the other hand, in the image reading apparatus 1, the request processing unit 31 causes the scanner 11 to start the image reading process when receiving the first request via the network interface 12, and before the timeout time elapses after receiving the first request. When the second request is received from the host device 2, the image data obtained by the image reading process is transmitted to the host device 2.

  Here, the management of the timeout time will be described. FIG. 3 is a flowchart for explaining the operation of the timeout time management unit 32 in FIG. FIG. 4 is a timing chart for explaining the operation of the timeout time management unit 32 in FIG.

  When the first request is received by the request processing unit 31 (step S1), the timeout time management unit 32 starts timing using a timer (not shown) (step S2).

  Thereafter, the timeout time management unit 32 determines whether or not a request other than the second request has been received from the host device 2 (step S3), and whether or not the timeout time To has elapsed from the time measurement start time in step S2 (step S4). And whether the second request is received from the host device 2 (step S5).

  When a request other than the second request is received from the host device 2 before the timeout time elapses and before the second request is received, the timeout time management unit 32 starts the mask time Tm from the time measurement start time in step S2. It is determined whether or not elapses (step S6). The mask time Tm is a predetermined time shorter than the timeout time To. For example, the timeout time To is set to 60 seconds, and the mask time Tm is set to 30 seconds.

  At this time, if the timeout time management unit 32 determines that the mask time Tm has elapsed from the time measurement start time in step S2, it determines whether or not the timeout time has been extended (step S7).

  If the timeout time has not been extended, the timeout time management unit 32 extends the timeout time To (step S8). The extended timeout time Toex is a time obtained by adding the extended time Te to the initial timeout time To. After extending the timeout time, the timeout time management unit 32 continues to perform the above-described monitoring (steps S3 to S5).

  On the other hand, when the time-out time management unit 32 determines that the mask time Tm has not elapsed from the time measurement start time at step S2 (step S6), and when the time-out time has already been extended (step S7), Monitoring (steps S3 to S5) is continued.

  When the second request is received before the timeout time (To or Toex) elapses (step S5), the timeout time management unit 32 determines whether or not the timeout time is extended (step S10). If the timeout time has been extended, the timeout time is reset to the value To before extension (step S11). Further, the timeout time management unit 32 ends the time measurement (step S12).

  When the timeout time has elapsed due to a communication failure in the network 3 or a failure in the host device 2 (step S4), the timeout time management unit 32 notifies the request processing unit 31 that a timeout has occurred. (Step S9). Upon receiving the timeout notification, the request processing unit 31 stops and terminates the image reading process started by the first request. Therefore, the request processing unit 31 discards the image data acquired according to the first request, and releases resources reserved for the image data. Then, the timeout time management unit 32 determines whether or not the timeout time is extended (step S10). If the timeout time is extended, the timeout time is reset to the value To before extension (step S10). S11). Further, the timeout time management unit 32 ends the time measurement (step S12).

  As described above, according to the first embodiment, when a request different from the second request is received from the host device 2 near the end of the timeout period, the second request is received from the host device 2. The timeout period is extended only once before the timeout period elapses. As a result, the time-out period can be adjusted without interrupting the image reading process as required, and the possibility that the second request is received after the time-out can be reduced.

  The storage device 112 is a device for storing data and computer programs. As the storage device 112, a hard disk drive, a nonvolatile memory, or the like is used. The storage device 112 stores a control program 121, user data 122, and history data 123.

  The control program 121 is a computer program for realizing a request processing unit 131 and a timeout time management unit 132 described later. The user data 122 is the same data as the user data 22 described above. The history data 123 is the same data as the history data 23 described above.

  The computer 113 has a CPU, a ROM, a RAM, and the like, loads a program into the RAM, and executes it by the CPU. Thereby, various processing units are realized. In the second embodiment, a request processing unit 131 and a timeout time management unit 132 are realized.

  The request processing unit 131 is a processing unit that receives a request for the scanner of the image reading apparatus 101 via the network interface 111, transmits the request to the image reading apparatus 101, and operates the scanner according to the request. In particular, the request processing unit 131 causes the image reading apparatus to start image reading processing when receiving a first request from the host apparatus 2, and receives a second request from the host apparatus 2 before the timeout time elapses after receiving the first request. Is received, the image data obtained by the image reading process is transmitted to the host device 2.

  When receiving the request, the request processing unit 131 adds a record for the request to the history data 123. The record includes a request type, a reception date and time, a user ID included in the request, and address information (IP address, MAC address, etc.) of the host device 2 that transmitted the request.

  The timeout time management unit 132 is a processing unit that manages the above-described timeout time. The timeout time management unit 132 extends the timeout time when the request processing unit 131 receives a request other than the second request after the predetermined time has elapsed since the first request was received and before the timeout time has elapsed. . The timeout time is extended by a predetermined rate or a predetermined time.

  In the second embodiment, the timeout time management unit 132 extends the timeout time only once for one second request.

  Next, the operation of the server device 103 will be described.

  The driver 102 a of the host apparatus 102 transmits a request to the image reading apparatus 101 via the server apparatus 103 using a protocol such as SOAP.

Receive.

  On the other hand, in the server apparatus 103, when the request processing unit 131 receives the first request, the request processing unit 131 causes the scanner of the image reading apparatus 101 to start image reading processing, and before the timeout period elapses after the first request is received. When the second request is received from the image reading apparatus, the image data obtained by the image reading process is acquired from the image reading apparatus 101 and transmitted to the host apparatus 2.

  In the second embodiment, the timeout time management unit 132 manages the timeout time in the same manner as the timeout time management unit 32 of the first embodiment.

  As described above, according to the second embodiment, the timeout period is managed by the server apparatus 103 in the same manner as in the first embodiment. As a result, the time-out period can be adjusted without interrupting the image reading process as required, and the possibility that the second request is received after the time-out can be reduced.

  Each embodiment described above is a preferred example of the present invention, but the present invention is not limited to these, and various modifications and changes can be made without departing from the scope of the present invention. It is.

  For example, in the first and second embodiments, the time-out time management units 32 and 132 set the time-out time To long (for example, 70 seconds) in the time zone where the number of requests is large, based on the request history data. However, the time-out time To may be set short (for example, 50 seconds) in the time zone in which the number of requests is small.

  For example, two thresholds are provided, and the timeout time is increased when the number of requests is greater than one threshold, and the timeout time is shortened when the number of requests is less than the other threshold.

  The number of requests may be the number of first requests in the history data 23 and 123 or the number of all requests (the same applies hereinafter). The time zone is obtained by dividing 24 hours by a predetermined time (for example, 4 hours).

  In the first and second embodiments, the timeout time management units 32 and 132 determine the number of requests for the user ID included in the first request or the address information of the host devices 2 and 102 that transmitted the first request. In a large time zone, a long timeout time is set, and in a time zone in which the number of requests for the user ID included in the first request or the address information of the host device 2 102 that transmitted the first request is small, the timeout time is set. You may make it set short. Thus, a timeout time suitable for each user or host device is set.

  In the first and second embodiments, the timeout time management units 32 and 132 set a longer timeout time in a predetermined daytime period (for example, from 6 o'clock to 18 o'clock), and the predetermined night time In the band (for example, from 18:00 to 6:00), the timeout time may be set short.

  In the first and second embodiments, when the continuous reading process is specified in the first request, the request processing units 31 and 131 start the image reading process every time the first request is received from the host device. When a second request is received from the host apparatus after the image reading process for one or a plurality of documents, the image data of one or a plurality of documents obtained by the image reading process is transmitted to the host devices 2 and 102. In the case of continuous reading processing, the timeout time management units 32 and 132 are longer than the timeout time To in the case of non-continuous reading by a predetermined extension time, and the timeout time between the first request and the next first request, A timeout time between the last first request and the second request may be set.

  In the first and second embodiments, when the image reading device 1 or 101 includes an automatic paper feeding device, the timeout time management units 32 and 132 use the output signals of the sensors installed on the tray of the automatic paper feeding device. Based on this, it is determined whether or not a document is placed on the automatic paper feeder, and when a document is placed on the automatic paper feeder, the timeout time is set longer by a predetermined extension time. Also good.

  In the first and second embodiments, the timeout time management units 32 and 132 refer to the user data 22 and 122 and set the length according to the user authority set in the user ID included in the first request. The timeout time To may be set. For example, in the case of an administrator user, the timeout time is set longer than in the case of a general user.

  In the first and second embodiments, the timeout time management units 32 and 132 may set the timeout time to a length corresponding to the department to which the user with the user ID included in the first request belongs. For example, a time-out time is set longer for other departments than the other departments in places where communication failures are likely to occur on the networks 3 and 104 or in remote departments.

  In addition, when extending the timeout time, a predetermined time according to each of the above conditions is added to the timeout time, and when reducing the timeout time, the predetermined time according to each of the above conditions is subtracted from the timeout time. .

  The present invention is applicable to, for example, a scanner connected to a network.
