PROBLEM TO BE SOLVED: To provide an X-ray diagnostic device the running cost of which can be reduced by limiting the capacity of a power supply facility required for the X-ray diagnostic device using a battery, when a commercial power supply and a battery power supply are used while being switched.SOLUTION: The X-ray diagnostic device comprises high voltage generation means, a first power supply, a battery, and power supply switching means. The high voltage generation means applies a high voltage to an X-ray tube in order to generate X-rays. The power supply switching means supplies the high voltage generation means with power from the first power supply or power from the battery while switching so that power is supplied from the first power supply upon receiving an instruction of fluoroscopy, and supplies power from the battery upon receiving an instruction of radiography.COPYRIGHT: (C)2012,JPO&INPIT【課題】バッテリーを使い、商用電源とバッテリー電源を切り替えて使う場合に、X線診断装置に必要な電源設備の容量を抑えて装置のランニングを低く抑えることができるX線診断装置を提供する。【解決手段】高電圧発生手段、第一の電源、バッテリー、及び、電源切替手段を有し、高電圧発生手段はX線管に高電圧を印加してX線を発生させ、電源切替手段は、X線透視の指示を受けたとき、前記第一の電源からの電力を前記高電圧発生手段に供給し、X線撮影の指示を受けたとき、前記バッテリーかの電力を前記高電圧発生手段に供給するように、第一の電源からの電力とバッテリーからの電力とを切り替えて高電圧発生手段に供給する。【選択図】図1
