PROBLEM TO BE SOLVED: To provide a radiation image pickup device that suppresses the reaction force occurring due to the contact of a radiation detector with a body thereof caused by temperature change.SOLUTION: A radiation image pickup device has a radiation detector 12 that detects a radiographic image produced by radiation that transmitted a subject, and is accommodated inside of a body 18 thereof. A surface of the body 18 comes in contact with the radiation detector 12 due to a warp of the radiation detector 12 caused by temperature change. The thickness of the surface of the body 18 is made variable in the vertical direction so that the radiation detector 12 is prevented from the application of stress by the reaction force generated through the contact of the radiation detector 12 with the body 18. Accordingly, damage to the radiation detector 12 is prevented.COPYRIGHT: (C)2012,JPO&INPIT【課題】温度変化による反りで放射線検出器がその筐体と接触で生じる反力を抑制する放射線画像撮影装置を提供する。【解決手段】被写体を透過した放射線による放射線画像を検出する放射線検出器12を筐体18内部に収めた放射線画像撮影装置において、放射線検出器12の温度変化により反りが生じ筐体18と接触する面と垂直方向に筐体厚さを可変とすることで、放射線検出器12が筐体18と接触することによる反力で、放射線検出器12にストレスが加わることを防ぐことが可能となり、放射線検出器12の損傷を防ぐ。【選択図】図5
