Abstract:
1. A detection apparatus comprising: a pixel array in which a plurality of pixels are arranged in a matrix of rows and columns, each pixel including a conversion element that converts radiation or light into electric charge and a switch element that outputs an electrical signal according to the electric charge; a plurality of driving wires, each being connected to a plurality of switch elements arranged in a row direction; a driving circuit unit configured to include a plurality of unit circuits provided for the plurality of corresponding driving wires configured to supply conducting voltage and non-conducting voltage of the switch elements to the plurality of corresponding driving wires; and a control unit configured to supply, to the driving circuit unit, a clock signal for defining timing at which the driving circuit unit supplies the conducting voltage to the driving wires, wherein the conducting voltage is voltage based on the clock signal, wherein the control unit supplies, to the plurality of unit circuits, a control signal for continuing to supply the non-conducting voltage to the driving wires, wherein each of the plurality of unit circuits receives the clock signal, an initiation signal for causing the unit circuit to begin to supply the conducting voltage to the corresponding driving wire, and a termination signal for causing the unit circuit to stop supplying the conducting voltage to the corresponding driving wire, and wherein each of the plurality of unit circuits includes a first circuit that supplies the conducting voltage to the corresponding driving wire in accordance with the initiation signal input to the unit circuit, a second circuit that supplies the non-conducting voltage input to the unit circuit to the corresponding driving wire in accordance with the termination signal input to the unit circuit, and a third circuit that continues to supply the non-conducting voltage to the corresponding driving wire in accordance with the control signal input to the unit circuit.
