PROBLEM TO BE SOLVED: To provide a radiographic imaging device of high frame rate capable of restraining an off-set from being fluctuated, and capable of restraining resolution from getting worse, and a control method therefor. SOLUTION: A reading out operation is carried out without irradiation with an X-ray, in an off-set reading out period, and only a timing of a gate pulse is differed compared with an X-ray reading out period. That is, switch elements are turned on and off sequentially as G1, G2, G3, ..., G6, in X-ray reading out, and the switch elements (TFT) are turned on in the off-set reading out period collectively with two lines, as combination of the G1 and G2, combination of the G3 and G4 and combination of the G5 and G6, to sum up picture elements. The reading out is carried out in a half of time compared with a time in the X-ray reading out period, by turning on the switches collectively with the two lines, by this manner.
