POWER FEEDING DEVICE FOR ELECTRONIC CASSETTE
First Claim
1. A power feeding device for an electronic cassette having a battery rechargeable by a noncontact power feeding operation, said power feeding device comprising:
- a signal sending section for sending a query signal as a query operation to check whether or not a cassette being set in a predetermined position is said electronic cassette having a power receiving function;
a signal receiving section for receiving a response signal issued by said electronic cassette in response to said query signal; and
a control section for starting said query operation;
for stopping said query operation, if no response signal is received for a predetermined time; and
for enabling said noncontact power feeding operation to said battery, if said set cassette is judged to be said electronic cassette having said power receiving function by reception of said response signal.

Abstract
An imaging support has a power feeding device that carries out a noncontact power feeding operation in an electromagnetic induction method. When a cassette is loaded in a cassette chamber of the imaging support, a power feeding controller of the power feeding device issues a query signal. In a case where the cassette loaded in the cassette chamber is an electronic cassette having a noncontact power receiving function, this electronic cassette issues a response signal answering the query signal. Upon receiving the response signal, the power feeding controller judges that the cassette is the electronic cassette, and starts the noncontact power feeding operation. On the other hand, in a case where the cassette loaded in the cassette chamber does not have the noncontact power receiving function, no response signal is issued. The power feeding controller stops issuing the query signal after a lapse of predetermined time.
