  • Patent number: 8053737
    Abstract: Even when there are plural radiographic image detection devices and external devices between which communication takes place, a link with a designated external device may be established easily and reliably. An electronic cassette used in imaging or an electronic cassette that stores generated image data in an image memory is attached to a handle that stores a console ID, which indicates a console that is to be specified as a target of communication. When the attachment of the electronic cassette with the handle is detected by an attachment detection section, a connection request signal is sent to the console indicated by the console ID stored in the handle. When a connection permission signal is received from the console, a link between the electronic cassette and the console is established.
