Title:
RADIOGRAPHIC IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2019184402
Kind Code:
A
Abstract:
To provide a mechanism that realizes downsizing of a housing while suppressing a reduction in power feeding efficiency in a radiographic imaging device that is contactlessly fed with power.SOLUTION: A radiographic imaging device comprises: a radiation detector 110 for detecting an incident radiation 201 and converting it into an image signal; a detector contact conductor 120 provided in proximity to the radiation detector 110; and a power receiving coil 130 arranged together with these in the inside of a housing 150, for receiving the electric energy supplied to the radiation detector 110 contactlessly between a power feeding coil 202 arranged on the outside of the housing 150 and itself. The power receiving coil 130 is arranged in a second range 102 including a first range 101 where the detector contact conductor 120 is formed in a normal direction (direction y) relative to an incidence plane 110a upon which the radiation 201 of the radiation detector 110 is incident, in such a way that the direction of a magnetic flux Φc passing through the center of the normal direction is a planar direction (direction x) of the incidence plane 110a and a direction heading toward the radiation detector 110.SELECTED DRAWING: Figure 1
