PROBLEM TO BE SOLVED: To provide a radiation imaging apparatus reducing a radiologists operation when mounting/detaching a mounting part of a pressure plate to/from an apparatus body.SOLUTION: A side plate of a moving member 64 is provided with a cylindrical regulating member 74 movable in a direction to advance into or retreat from an insertion region 72 of an insertion member 54 into which the mounting part is inserted. The regulating member 74 is made movable into a permissible position, a locking position and a lock release position. Consequently, when the mounting part 44 is detached from the insertion member 54 in a state of the regulating member 74 being arranged in the lock release position, for example, the regulating member 74 is moved into the permissible position by the biasing force of a coil spring 70. Thus, the radiologists operation can be reduced when mounting/detaching the mounting part 44 of the pressure plate 26 to/from the insertion member 54.COPYRIGHT: (C)2013,JPO&INPIT【課題】押圧板の取付部を装置本体に装着及び離脱させる際に、技師の動作を少なくすることができる放射線撮像装置を得る。【解決手段】移動部材64の側板には、取付部が差し込まれる被差込部材54の差込領域72に対して進入又は退避する方向に移動可能とされる円柱状の規制部材74が設けられている。そして、規制部材74を許容位置、ロック位置及びロック解除位置に移動可能とすることで、例えば、ロック解除位置に規制部材74が配置される状態で、取付部44を被差込部材54から離脱させると規制部材74はコイルスプリング70の付勢力により許容位置に移動する。このように、押圧板26の取付部44を被差込部材54に装着及び離脱させる際に、技師の動作を少なくすることができる。【選択図】図1
