　ステップＳ３において、装着判定部４１が、受信部３０が被検体Ｈに装着されていないと判定した場合（ステップＳ３：Ｎｏ）、ステップＳ１に戻り、処理が継続される。 In step S3, when the attachment determination unit 41 determines that the receiving unit 30 is not attached to the subject H (step S3: No), the process returns to step S1 to continue processing.
　同様に、ステップＳ５において、設定部４３が、所定時間内に受信部３０が情報を受信していないと判定した場合（ステップＳ５：Ｎｏ）、ステップＳ１に戻り、処理が継続される。 Similarly, in step S5, when the setting unit 43 determines that the receiving unit 30 has not received information within the predetermined time (step S5: No), the process returns to step S1 to continue processing.
　ステップＳ７において、判定部４４が、受信した情報に含まれる機器情報が、記憶部４５に記憶されている受信対象の機器情報ではないと判定した場合（ステップＳ７：Ｎｏ）、記憶部４５は、その情報に含まれる画像を記憶せず、ステップＳ１に戻り、処理が継続される。 In step S7, when the determination unit 44 determines that the device information included in the received information is not the device information to be received stored in the storage unit 45 (step S7: No), the storage unit 45 The image included in the information is not stored, and the process returns to step S1 to continue processing.
