INFORMATION PROCESSING DEVICE, CONTROL METHOD, AND PROGRAM

To eliminate connection abnormality while maintaining connection between both devices even when the communication abnormality occurs between a main body unit 100A and an operation unit 100B.SOLUTION: A main body unit 100A comprises: a wired I/F circuit 107 and a wired I/F control unit 322 as a wired communication unit 323 communicating with an operation unit 100B via a wired communication path 10; and a wireless I/F circuit 108 and a wireless I/F control unit 324 as a wireless communication unit 325 communicating with the operation unit 100B via a wireless communication path 20. In the main body unit 100A, when communication abnormality occurs in the wired communication path, a connection management unit 321 switches the communication unit communicating with the operation unit 100B to the wireless communication unit 325, and a reset unit 326 resets the wired I/F circuit 107 and the wired I/F control unit 322 while maintaining communication with the operation unit 100B via the wireless communication path.SELECTED DRAWING: Figure 3 【課題】本体部１００Ａと操作部１００Ｂとの間で通信異常が発生した場合であっても、両装置間の通信を維持しつつ、通信異常を解消する。【解決手段】本体部１００Ａは、有線通信路１０を介して操作部１００Ｂと通信する有線通信部３２３として有線Ｉ／Ｆ回路１０７と有線Ｉ／Ｆ制御部３２２を備え、無線通信路２０を介して操作部１００Ｂとの間で通信する無線通信部３２５として無線Ｉ／Ｆ回路１０８と無線Ｉ／Ｆ制御部３２４を備える。本体部１００Ａは、有線通信路における通信異常が発生した場合に、接続管理部３２１が操作部１００Ｂとの間で通信する通信部を無線通信部３２５に切り替えると共に、操作部１００Ｂとの間で無線通信路を介した通信を維持した状態で、リセット部３２６が有線Ｉ／Ｆ回路１０７と有線Ｉ／Ｆ制御部３２２をリセットする。【選択図】図３
