PROBLEM TO BE SOLVED: To provide an electron beam monitoring device in an electron beam sterilization unit, capable of visually confirming the irradiation state of electron beams irradiated from an irradiation nozzle.SOLUTION: The electron beam monitoring device in an electron beam sterilization unit includes an electron beam irradiation nozzle 31 of which the irradiation hole at the end is inserted in a container B for sterilization of the inner surface of the container B during traveling along a transport route together with the container B. In an idle route portion Ld where the electron beam irradiation nozzle 31 travels alone along the transport route, a light-emitting member 32 which emits light when exposed to the electron beams irradiated from the irradiation hole of the electron beam irradiation nozzle 31. A display screen 35 is provided to display the luminous state as the irradiation state of electron beams, based on the signals of the imaging device 33 for imaging the emitting state of the light-emitting member 32.COPYRIGHT: (C)2015,JPO&INPIT【課題】電子線照射ノズルから照射される電子線の照射状態を、視覚を通じて確認できる電子線滅菌装置における電子線監視装置を提供する。【解決手段】容器Bと共に搬送経路に沿って移動中に、先端の照射口を容器Bに挿入して容器Bの内面を滅菌する電子線照射ノズル31を具備した電子線滅菌装置における電子線監視装置であって、搬送経路で電子線照射ノズル31が単独で移動するアイドル経路部Ldに、電子線照射ノズル31の照射口から照射される電子線により、発光する発光部材32を配置し、発光部材32の発光状態を撮像する撮像装置33の信号に基づいて、発光状態を電子線の照射状態として表示する表示画面35を設けた。【選択図】図1
