すると、端末装置２０の無線通信管理部２０３は、無線通信インターフェース２５を介した画像形成装置１０との無線通信を中止する（ステップＳ２０３）。無線通信管理部２０３は、総時間通知を受信してから総時間（総時間通知に含まれる）が経過すると（ステップＳ２０４、ＹＥＳ）、無線通信インターフェース２５を介した画像形成装置１０との無線通信を再開する（ステップＳ２０５）。 Then, the wireless communication management unit 203 of the terminal device 20 cancels the wireless communication with the image forming apparatus 10 via the wireless communication interface 25 (step S203). When the total time (included in the total time notification) elapses after receiving the total time notification (step S204, YES), the wireless communication management unit 203 wirelessly communicates with the image forming apparatus 10 via the wireless communication interface 25. Is restarted (step S205).

例えば、無線通信管理部２０３は、無線通信インターフェース２５を介した画像形成装置１０との無線通信を切断（完全に終了）することにより、無線通信を中止すればよい（ステップＳ２０３）。この場合、無線通信管理部２０３は、無線通信インターフェース２５を介した画像形成装置１０との無線通信を接続する（改めてネゴシエーションする）ことにより、無線通信を再開すればよい（ステップＳ２０５）。 For example, the wireless communication management unit 203 may stop the wireless communication by disconnecting (completely ending) the wireless communication with the image forming apparatus 10 via the wireless communication interface 25 (step S203). In this case, the wireless communication management unit 203 may restart the wireless communication by connecting (negotiating again) the wireless communication with the image forming apparatus 10 via the wireless communication interface 25 (step S205).

あるいは、無線通信管理部２０３は、無線通信インターフェース２５を介して画像形成装置１０とデータを送受信しないことにより、無線通信を中止すればよい（ステップＳ２０３）。要するに、無線通信管理部２０３は、画像形成装置１０にパケットを送信せず、画像形成装置１０が送信したパケットを受け取らなければよい。この場合、無線通信管理部２０３は、無線通信インターフェース２５を介して画像形成装置１０とデータを送受信することにより、無線通信を再開すればよい（ステップＳ２０５）。要するに、無線通信管理部２０３は、画像形成装置１０にパケットを送信したり、画像形成装置１０が送信したパケットを受け取ったりすればよい。 Alternatively, the wireless communication management unit 203 may stop the wireless communication by not transmitting / receiving data to / from the image forming apparatus 10 via the wireless communication interface 25 (step S203). In short, the wireless communication management unit 203 does not have to transmit the packet to the image forming apparatus 10 and does not have to receive the packet transmitted by the image forming apparatus 10. In this case, the wireless communication management unit 203 may restart the wireless communication by transmitting and receiving data to and from the image forming apparatus 10 via the wireless communication interface 25 (step S205). In short, the wireless communication management unit 203 may transmit a packet to the image forming apparatus 10 or receive the packet transmitted by the image forming apparatus 10.

無線通信を再開すると、端末装置２０のジョブ問い合わせ部２０４は、ジョブが終了したか否かの問い合わせを、無線通信インターフェース２５を介して画像形成装置１０に送信する（ステップＳ２０６）。なお、総時間通知を受信してから総時間が経過しているため（ステップＳ２０４、ＹＥＳ）、画像形成装置１０にトラブル等が無ければ、ジョブは終了している筈である。 When the wireless communication is resumed, the job inquiry unit 204 of the terminal device 20 transmits an inquiry as to whether or not the job has been completed to the image forming apparatus 10 via the wireless communication interface 25 (step S206). Since the total time has elapsed since the total time notification was received (step S204, YES), the job should have been completed if there is no trouble in the image forming apparatus 10.

画像形成装置１０のジョブ管理部１０４は、ジョブが終了したか否かの問い合わせを、無線通信インターフェース１３を介して端末装置２０から受信する（ステップＳ１０４）。すると、ジョブ管理部１０４は、ジョブが終了したか否かを判断する（ステップＳ１０５）。ジョブ管理部１０４は、ジョブが終了したと判断すると（ステップＳ１０５、ＹＥＳ）、ジョブが終了したことを示す通知である終了通知を、無線通信インターフェース１３を介して端末装置２０に送信する（ステップＳ１０６）。 The job management unit 104 of the image forming apparatus 10 receives an inquiry as to whether or not the job has been completed from the terminal apparatus 20 via the wireless communication interface 13 (step S104). Then, the job management unit 104 determines whether or not the job has been completed (step S105). When the job management unit 104 determines that the job has been completed (YES in step S105), the job management unit 104 transmits a end notification, which is a notification indicating that the job has been completed, to the terminal device 20 via the wireless communication interface 13 (step S106). ).

端末装置２０のジョブ問い合わせ部２０４は、終了通知を、無線通信インターフェース２５を介して画像形成装置１０から受信すると（ステップＳ２０７、ＹＥＳ）、無線通信インターフェース２５を介した画像形成装置１０との無線通信を中止する（ステップＳ２０８）。無線通信を中止する具体的な方法は上記と同様である。 When the job inquiry unit 204 of the terminal device 20 receives the end notification from the image forming device 10 via the wireless communication interface 25 (step S207, YES), the job inquiry unit 204 wirelessly communicates with the image forming device 10 via the wireless communication interface 25. Is stopped (step S208). The specific method for stopping the wireless communication is the same as above.

一方、画像形成装置１０のジョブ管理部１０４は、ジョブが終了していないと判断すると（ステップＳ１０５、ＮＯ）、ジョブの遅延時間を示す通知である遅延時間通知を、無線通信インターフェース１３を介して端末装置２０に送信する（ステップＳ１０７）。 On the other hand, when the job management unit 104 of the image forming apparatus 10 determines that the job has not been completed (step S105, NO), the job management unit 104 notifies the delay time, which is a notification indicating the delay time of the job, via the wireless communication interface 13. It is transmitted to the terminal device 20 (step S107).

端末装置２０のジョブ問い合わせ部２０４は、遅延時間通知を、無線通信インターフェース２５を介して画像形成装置１０から受信する（ステップＳ２０７、ＮＯ、ステップＳ２０９）。 The job inquiry unit 204 of the terminal device 20 receives the delay time notification from the image forming device 10 via the wireless communication interface 25 (steps S207, NO, step S209).

すると、端末装置２０の無線通信管理部２０３は、無線通信インターフェース２５を介した画像形成装置１０との無線通信を中止する（ステップＳ２０３）。無線通信管理部２０３は、問い合わせを送信してから遅延時間（遅延時間通知に含まれる）が経過すると（ステップＳ２０４、ＹＥＳ）、無線通信インターフェース２５を介した画像形成装置１０との無線通信を再開する（ステップＳ２０５）。無線通信を中止及び再開する具体的な方法は上記と同様である。 Then, the wireless communication management unit 203 of the terminal device 20 cancels the wireless communication with the image forming apparatus 10 via the wireless communication interface 25 (step S203). When the delay time (included in the delay time notification) elapses after the inquiry is transmitted (step S204, YES), the wireless communication management unit 203 resumes wireless communication with the image forming apparatus 10 via the wireless communication interface 25. (Step S205). The specific method for suspending and resuming wireless communication is the same as described above.

無線通信を再開すると、端末装置２０のジョブ問い合わせ部２０４は、ジョブが終了したか否かの問い合わせを、無線通信インターフェース２５を介して画像形成装置１０に送信する（ステップＳ２０６）。なお、問い合わせを送信してから遅延時間が経過しているため（ステップＳ２０４、ＹＥＳ）、画像形成装置１０にトラブル等が無ければ、ジョブは終了している筈である。 When the wireless communication is resumed, the job inquiry unit 204 of the terminal device 20 transmits an inquiry as to whether or not the job has been completed to the image forming apparatus 10 via the wireless communication interface 25 (step S206). Since the delay time has elapsed since the inquiry was transmitted (step S204, YES), the job should have been completed if there is no trouble in the image forming apparatus 10.

The terminal device 1 transmits a job execution request R1 for executing the job 1 to the image forming device 10 (step S201). The image forming apparatus 10 receives the job execution request R1 from the terminal apparatus 1 (step S101). The image forming apparatus 10 adds the waiting time (0 seconds) required to start the job 1 and the required time (300 seconds) required to execute the job 1, so that the total time required for the job 1 (0 + 300 = 300). Seconds) is calculated (step S102). The image forming apparatus 10 transmits the total time notification T1 indicating the total time (300 seconds) to the terminal apparatus 20 (step S103). The image forming apparatus 10 starts executing the job 1 after the waiting time (0 seconds) has elapsed. When the terminal device 1 receives the total time notification T1 indicating the total time (300 seconds) from the image forming device 10 (step S202), the terminal device 1 cancels the wireless communication (step S203). When the total time (300 seconds) has elapsed since the terminal device 1 received the total time notification T1 (step S204, YES), the terminal device 1 resumes wireless communication (step S205) and inquires whether or not the job 1 has been completed. I1 is transmitted to the image forming apparatus 10 (step S206). The image forming apparatus 10 receives the inquiry I1 from the terminal apparatus 1 (step S104). When the image forming apparatus 10 determines that the job 1 has been completed (YES in step S105), the image forming apparatus 10 transmits an end notification E1 indicating that the job 1 has been completed to the terminal device 1 (step S106).

By adding the time required to execute the job 3 (150 seconds) and the time required to execute the job 3 (700 seconds), the total time required to complete the job 3 (700 + 150 = 850 seconds) is calculated (step S102). The image forming apparatus 10 transmits a total time notification T3 indicating the total time (850 seconds) to the terminal device 3 (step S103).

The reception is after the interruption of job 1. Other conditions are the same as in the first specific example. The same contents as the first specific example will be omitted, and the differences will be mainly described.

ジョブ１を説明する。画像形成装置１０は、問い合わせＩ１を端末装置１から受信する（ステップＳ１０４）。画像形成装置１０は、ジョブ１が終了していないと判断すると（ステップＳ１０５、ＮＯ）、ジョブ１の遅延時間（６０秒）を示す遅延時間通知Ｄ１を端末装置１に送信する（ステップＳ１０７）端末装置１は、遅延時間通知Ｄ１を画像形成装置１０から受信すると（ステップＳ２０７、ＮＯ）、無線通信を中止し（ステップＳ２０３）、問い合わせＩ１を送信してから遅延時間（６０秒）が経過すると（ステップＳ２０４、ＹＥＳ）、無線通信を再開する（ステップＳ２０５）。端末装置１は、ジョブ１が終了したか否かの問い合わせＩ２を画像形成装置１０に送信する（ステップＳ２０６）。画像形成装置１０は、問い合わせＩ２を端末装置１から受信する（ステップＳ１０４）。画像形成装置１０は、ジョブ１が終了したと判断すると（ステップＳ１０５、ＹＥＳ）、ジョブ１が終了したことを示す終了通知Ｅ２を端末装置１に送信する（ステップＳ１０６）。 Job 1 will be described. The image forming apparatus 10 receives the inquiry I1 from the terminal apparatus 1 (step S104). When the image forming apparatus 10 determines that the job 1 has not been completed (step S105, NO), the image forming apparatus 10 transmits a delay time notification D1 indicating the delay time (60 seconds) of the job 1 to the terminal device 1 (step S107). When the device 1 receives the delay time notification D1 from the image forming device 10 (step S207, NO), the wireless communication is stopped (step S203), and when the delay time (60 seconds) elapses after the inquiry I1 is transmitted (step S203).

８．結語 8. Conclusion

端末装置が画像形成装置にジョブ（典型的には、印刷ジョブ）を無線通信を介して送信し、画像形成装置がジョブ終了を端末装置に無線通信を介して通知する技術がある。印刷ジョブによっては、ジョブ終了までに比較的長い時間が掛かることがある（ページ数や部数が多いなど）。また、画像形成装置に複数のジョブが登録されている場合は、先行するジョブが終了するまで、ジョブの実行開始を待機する必要があるため、結果的に、ジョブ終了までに時間がかかる。印刷ジョブが終了するまでの比較的長い期間、端末装置と画像形成装置との無線接続を継続すると、例えば、以下の様な問題が生じるおそれがある。端末は、無線接続に必要な電力を消費する。また、画像形成装置の無線接続の同時接続数が上限に達していると、ジョブを送信した端末装置は、新たなジョブを送信するのではなく単に画像形成装置のジョブ実行状態を知ればよいだけにすぎないのに、新たにジョブを送信したい端末装置が、画像形成装置と無線接続できない。 There is a technique in which a terminal device transmits a job (typically a print job) to an image forming device via wireless communication, and the image forming device notifies the terminal device of the end of the job via wireless communication. Depending on the print job, it may take a relatively long time to complete the job (for example, the number of pages or the number of copies is large). Further, when a plurality of jobs are registered in the image forming apparatus, it is necessary to wait for the start of job execution until the preceding job is completed, and as a result, it takes time to complete the job. If the wireless connection between the terminal device and the image forming device is continued for a relatively long period of time until the print job is completed, for example, the following problems may occur. The terminal consumes the power required for wireless connection. Further, when the number of simultaneous wireless connections of the image forming apparatus has reached the upper limit, the terminal device that has sent the job only needs to know the job execution status of the image forming apparatus instead of sending a new job. However, the terminal device that wants to send a new job cannot wirelessly connect to the image forming device.

（１）以上のような事情に鑑み、本実施形態によれば、画像形成装置１０は、ジョブ実行要求を端末装置２０から受信すると、ジョブの開始までに掛かる待機時間と、ジョブの実行に掛かる所要時間とを加算することにより、ジョブの終了までに掛かる総時間を算出し、総時間を示す通知である総時間通知を、端末装置２０に送信する。端末装置２０は、総時間通知を画像形成装置１０から受信すると、画像形成装置１０との無線通信を中止し、総時間通知を受信してから総時間が経過すると、画像形成装置１０との無線通信を再開し、ジョブが終了したか否かの問い合わせを、画像形成装置１０に送信する。画像形成装置１０は、問い合わせを、端末装置２０から受信すると、ジョブが終了したか否かを判断し、ジョブが終了したと判断すると、ジョブが終了したことを示す通知である終了通知を、端末装置２０に送信する。これにより、端末装置２０は、画像形成装置１０と無線通信する必要が無い時間（即ち、ジョブを送信し、総時間通知を受信してから、ジョブの終了までに掛かる総時間が経過するまで）は無線通信を中止するので、電力の消費を抑えられる。端末装置２０は、総時間が経過すると、画像形成装置１０との無線通信を再開するので、トラブルが無ければジョブが丁度終了している筈の頃に、ジョブが終了したことを知ることができる。これにより、端末装置２０にとって必要なときのみ画像形成装置１０と無線通信し、その必要が無いときは画像形成装置１０と無線通信しないので、端末装置２０の電力の消費を抑えつつ、ユーザーにとって不便が生じない。 (1) In view of the above circumstances, according to the present embodiment, when the image forming apparatus 10 receives the job execution request from the terminal apparatus 20, the waiting time required for the start of the job and the execution of the job are required. By adding the required time, the total time required to complete the job is calculated, and the total time notification, which is a notification indicating the total time, is transmitted to the terminal device 20. When the terminal device 20 receives the total time notification from the image forming device 10, the wireless communication with the image forming device 10 is stopped, and when the total time elapses after receiving the total time notification, the terminal device 20 wirelessly communicates with the image forming device 10. Communication is resumed, and an inquiry as to whether or not the job is completed is transmitted to the image forming apparatus 10. When the image forming apparatus 10 receives the inquiry from the terminal device 20, it determines whether or not the job has been completed, and when it determines that the job has been completed, the image forming apparatus 10 notifies the terminal that the job has been completed. It is transmitted to the device 20. As a result, the terminal device 20 does not need to wirelessly communicate with the image forming device 10 (that is, from the time when the job is transmitted and the total time notification is received until the total time required until the end of the job elapses). Stops wireless communication, so power consumption can be reduced. Since the terminal device 20 resumes wireless communication with the image forming apparatus 10 when the total time elapses, it can be known that the job has been completed when the job should have been completed if there is no trouble. .. As a result, the terminal device 20 wirelessly communicates with the image forming apparatus 10 only when necessary, and does not wirelessly communicate with the image forming apparatus 10 when it is not necessary, which is inconvenient for the user while suppressing the power consumption of the terminal apparatus 20. Does not occur.

（２）本実施形態によれば、画像形成装置１０は、ジョブが終了していないと判断すると、ジョブの遅延時間を示す通知である遅延時間通知を、端末装置２０に送信する。端末装置２０は、遅延時間通知を、画像形成装置１０から受信すると、画像形成装置１０との無線通信を中止し、問い合わせを送信してから遅延時間が経過すると、画像形成装置１０との無線通信を再開し、ジョブが終了したか否かの問い合わせを、画像形成装置１０に送信する。これにより、端末装置２０は、画像形成装置１０と無線通信する必要が無い時間（即ち、問い合わせを送信してから、ジョブの遅延時間が経過するまで）は無線通信を中止するので、電力の消費を抑えられる。端末装置２０は、遅延時間が経過すると、画像形成装置１０との無線通信を再開するので、トラブルが無ければジョブが丁度終了している筈の頃に、ジョブが終了したことを知ることができる。これにより、端末装置２０にとって必要なときのみ画像形成装置１０と無線通信し、その必要が無いときは画像形成装置１０と無線通信しないので、端末装置２０の電力の消費を抑えつつ、ユーザーにとって不便が生じない。 (2) According to the present embodiment, when the image forming apparatus 10 determines that the job has not been completed, the image forming apparatus 10 transmits a delay time notification indicating the delay time of the job to the terminal apparatus 20. When the terminal device 20 receives the delay time notification from the image forming apparatus 10, the wireless communication with the image forming apparatus 10 is stopped, and when the delay time elapses after transmitting the inquiry, the terminal device 20 wirelessly communicates with the image forming apparatus 10. Is restarted, and an inquiry as to whether or not the job is completed is transmitted to the image forming apparatus 10. As a result, the terminal device 20 stops the wireless communication during the time when it is not necessary to wirelessly communicate with the image forming device 10 (that is, from the transmission of the inquiry until the delay time of the job elapses), so that the power consumption is consumed. Can be suppressed. When the delay time elapses, the terminal device 20 resumes wireless communication with the image forming apparatus 10, so that it can be known that the job has been completed when the job should have been completed if there is no trouble. .. As a result, the terminal device 20 wirelessly communicates with the image forming apparatus 10 only when necessary, and does not wirelessly communicate with the image forming apparatus 10 when it is not necessary, which is inconvenient for the user while suppressing the power consumption of the terminal apparatus 20. Does not occur.

（３）本実施形態によれば、端末装置２０は、終了通知を画像形成装置１０から受信すると、画像形成装置１０との無線通信を中止する。これにより、端末装置２０は、画像形成装置１０と無線通信する必要が無い時間（即ち、ジョブ終了後）は無線通信を中止するので、電力の消費を抑えられる。 (3) According to the present embodiment, when the terminal device 20 receives the end notification from the image forming device 10, the terminal device 20 stops the wireless communication with the image forming device 10.
