This invention has one object to provide radiographic apparatus for acquiring a radioscopic image through superimposing of strip images. The radiographic apparatus allows prevention of blurring in the image with shortened imaging time for acquiring a clearer radioscopic image. According to the configuration of this invention, the FPD-4 is entirely within an imaging range throughout continuous taking of the strip images. In so doing, a minimum movement distance of the FPD-4 may be achieved in continuous taking of the strip images. Even when movement of the FPD-4 deviates from original setting, a range of the deviation may be suppressed to be small, since the movement distance of the FPD-4 is suppressed to be small. Consequently, superimposing of the strip images may realize acquisition of a clearer radioscopic image.
