<p><P>PROBLEM TO BE SOLVED: To provide a compact electronic cassette, and to reliably prevent image quality degradation due to noise. <P>SOLUTION: A back cover 55 of a casing 27 of the electronic cassette 21 includes an electric field coupling power reception electrode 61 for non-contact power supply. When the electronic cassette 21 is set in a holder 30a, 30b, the power reception electrode 61 receives power from a power supply electrode 82 of a power supply device 81. A switch 91 is connected to a casing ground 92 of the electronic cassette 21 and a charging circuit 93 of a battery 41, and selectively changes over the connection with the power reception electrode 61. The switch 91 is laid down toward the casing ground 92 during imaging and transmitting image data to an imaging controller 23, and the power reception electrode 61 functions as an electromagnetic shield. The switch 91 is laid down toward the charging circuit 93 in the other cases. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
