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. |
