    • PURPOSE: A readout device and a digital X-ray detecting apparatus are provided to simplify the structure of the apparatus by using a structure for adjusting a threshold voltage according to the voltage stored at a capacitor. CONSTITUTION: A capacitor(121) is serially connect to a pixel electrode(114) which collects electric charges, and stores the electric charges collected by the pixel electrode. The first transistor(122) changes a threshold voltage according to the voltage saved in the capacitor and outputs an output signal, changed according to the changed threshold voltage, to an image forming part which generates an image. The second transistor(123) whose one end is connected to the capacitor and the other end is connected to the ground, resets the capacitor according to a control signal.
