The electrode 134A is in contact with a first radiation image output electrode 74A provided on a predetermined surface of the electronic cassette 12, and the second electrode 134B is on a surface different from the predetermined surface of the electronic cassette 12. Second radiation provided Contacting the electrode 74B image output. Therefore, according to the cassette stand 84 according to the present embodiment, it is possible to stably connect to all the electronic cassettes 12 having different sizes and output a radiation image. Further, according to the cassette stand 84 according to the present embodiment, the electronic cassette 12 is used in an operating field or the like, and blood or the like adheres to the radiation image output electrode on a certain surface, so that the corresponding electrode of the cassette stand 84 Even if it becomes impossible to conduct with the other electrode, it is possible to conduct with the corresponding electrode of the cassette stand 84 by the other output electrode to which blood does not adhere. Thus, even when blood or the like adheres to a certain surface, the electrical connection can be made more stably and the radiation image can be output.

  In the present embodiment, the case where the electronic cassette 12 is charged and the radiation image is read by the cassette stand 84 is described as an example. However, the present invention is not limited to this. Any one of charging and reading of a radiation image may be performed. When only charging is performed, a charging electrode is provided on at least one of the bottom surface and the side surface of the electronic cassette 12, and an electrode connected to the charging unit 146 is provided on at least one of the bottom surface and the side surface of the insertion groove 172 of the cassette stand 84. May be provided. When only reading out the radiographic image, a radiographic image output electrode is provided on at least one of the bottom surface and the side surface of the electronic cassette 12, and at least one of the bottom surface and the side surface of the insertion groove 172 of the cassette stand 12 is provided. An electrode connected to the reading portion 108 may be provided.

  In the present embodiment, the example in which the charging electrode and the radiation image output electrode are continuously provided in the length direction of the groove portion on the bottom surface of the electronic cassette 12 and the side surface continuous to the bottom surface has been described. The present invention is not limited to this, and at least one of the charging electrode and the radiation image output electrode may be continuously provided on at least one predetermined surface of the electronic cassette 12 in the length direction of the groove. Good.
