PROBLEM TO BE SOLVED: To provide a protective cover for a photoreceptor for intrabuccal X-ray photography which protects a photoreceptor when performing X-ray photography, and in which a photoreceptor can be easily taken out without causing saliva to adhere to the photoreceptor after the X-ray photograph is performed.SOLUTION: A protective cover 1 includes an interior member 2 and an exterior member 3. The interior member 2 and the exterior member 3 include housing parts 11 and 21, and openings 10 and 20 respectively. An imaging plate 4 is housed in the housing part 11 of the interior member 2, and the interior member 2 is housed in the housing part 21 of the exterior member 3. An opening 10 side of the interior member 2 is arranged on the depth side of the housing part 21. The imaging plate 4 is exposed from the opening 10 of the interior member 2 in the housing part 21, and the exterior member 3 is gripped to fix the exterior member 3 and the imaging plate 4. In this state, when the interior member 2 is pulled out of the opening 20 of the exterior member 3, the imaging plate 4 remains in the housing part 21. After this, when the opening 20 of the exterior member 3 is turned downward, the imaging plate 4 drops from the housing part 21.COPYRIGHT: (C)2015,JPO&INPIT【課題】X線撮影時には感光体を保護し、撮影後は、感光体に唾液を付着させることなく容易に感光体を取り出すことができる口内法X線撮影用の感光体の保護カバーを提供することである。【解決手段】保護カバー1は、内装部材2と外装部材3を有する。内装部材2、外装部材3は、各々収容部11、21と開口10、20を有する。内装部材2の収容部11にイメージングプレート4を収容し、外装部材3の収容部21に内装部材2を収容する。内装部材2の開口10側を収容部21の奥側に配置する。収容部21内で内装部材2の開口10からイメージングプレート4が露出しており、外装部材3を把持して外装部材3とイメージングプレート4とを固定する。この状態で外装部材3の開口20から内装部材2を引き抜くと、収容部21にイメージングプレート4が残る。その後、外装部材3の開口20を下向きにすると、収容部21からイメージングプレート4が落下する。【選択図】図5
