In FIG. 4, only the connection relationship between one pixel 74 including the photoelectric conversion layer 68 and the storage capacitor 72 and one TFT 70 is shown, and the configuration of the other pixels 74 is omitted. Amorphous selenium must be used within a predetermined temperature range because its structure changes and its function decreases at high temperatures. Therefore, it is preferable to provide means for cooling the radiation detector 60 in the electronic cassette 32. Further, the radiation detector 60 indirectly uses a phosphor material and a photoelectric conversion element (photodiode) instead of the X-ray-charge conversion material that directly converts the radiation X such as amorphous selenium into electric charges. You may convert into an electric charge. As phosphor materials, gadolinium sulfate (GOS) and cesium iodide (CsI) are well known. In this case, X-ray-light conversion is performed using a fluorescent material, and light-charge conversion is performed using a photodiode of a photoelectric conversion element.

Each gate line 76 is connected to a line scanning drive unit 80, and each signal line 78 is connected to a multiplexer 82 constituting a reading circuit.

  Control signals Von and Voff for controlling on / off of the TFTs 70 arranged in the row direction are supplied from the line scanning drive unit 80 to the gate line 76. In this case, the line scan driving unit 80 includes a plurality of switches SW1 for switching the gate lines 76, and an address decoder 84 for outputting a selection signal for selecting one of the switches SW1. An address signal is supplied from the electronic cassette control unit 64 to the address decoder 84.

  Further, the charge held in the storage capacitor 72 of each pixel 74 flows out to the signal line 78 through the TFTs 70 arranged in the column direction. This charge is amplified by the amplifier 86. A multiplexer 82 is connected to the amplifier 86 via a sample and hold circuit 88. The multiplexer 82 includes a plurality of switches SW2 for switching the signal lines 78, and an address decoder 90 that outputs a selection signal for selecting one of the switches SW2. An address signal is supplied from the electronic cassette control unit 64 to the address decoder 90. An A / D converter 92 is connected to the multiplexer 82, and radiation image information converted into a digital signal by the A / D converter 92 is supplied to the electronic cassette control unit 64.

Further, the vent 96 only needs to be arranged corresponding to the heat generating part. When the heat generating part is arranged along one of the four sides 54A, 54B, 54C, 54D, one side thereof is required. It suffices if the side surfaces 94A, 94B, 94C, and 94D are formed. Accordingly, the vent 96 may be formed at least on any of the side surfaces 94A, 94B, 94C, 94D.

  Further, when the vent hole 96 is formed on two side surfaces, the vent port 96 may be formed on opposite side surfaces (for example, the side surface 94A and the side surface 94C), and adjacent side surfaces (for example, the side surface 94A). The side surface 94B) may be formed.

  The casing 54 is provided with a lid member 98 that covers the vent 96.

  The lid member 98 is formed of an endless annular band. The lid member 98 covers the side surfaces 94A, 94B, 94C, 94D and the vent hole 96 from the outer surface side of the housing 20, and is provided on the side surfaces 94A, 94B, 94C, 94D of the housing 54 so as to tighten each side surface.
