and an LED row in which a plurality of LEDs that emit an ultraviolet ray are arranged in a row and which directly or indirectly irradiates a radiation incident surface of the radiographic imager with the ultraviolet ray emitted by each LED, the radiographic imager being held by the holder. ## Claims ### Claim 1 A sterilizer comprising: a holder that holds a portable radiographic imager; and an LED row in which a plurality of LEDs that emit an ultraviolet ray are arranged in a row and which directly or indirectly irradiates a radiation incident surface of the radiographic imager with the ultraviolet ray emitted by each LED, the radiographic imager being held by the holder. ### Claim 2 (depends on 1) The sterilizer according to claim 1, wherein the LED row is disposed such that each LED emits the ultraviolet ray toward the radiation incident surface, and a first driver is further provided that moves the LED row in a direction along the radiation incident surface and orthogonal to a direction in which the plurality of LEDs are arranged. ### Claim 3 (depends on 1) The sterilizer according to claim 1, wherein the LED row is fixed at a predetermined position such that each LED emits the ultraviolet ray toward the radiation incident surface, and a second driver is further provided that moves the radiographic imager in a direction along the radiation incident surface and orthogonal to a direction in which the plurality of LEDs are arranged. ### Claim 4 (depends on 1) The sterilizer according to claim 1, wherein the LED row is disposed such that each LED is arranged along the radiation incident surface, and a third driver is further provided that rotates the LED row around a straight line as a rotation axis, the straight line extending along a direction in which the plurality of LEDs are arranged. ### Claim 5 (depends on 1) The sterilizer according to claim 1, further comprising: a light guiding plate having a plate shape, that is disposed such that a main surface of the light guiding plate faces the radiation incident surface of the radiographic imager held by the holder, and that diffuses linear light incident from a side surface of the light guiding plate to emit the light in a planar shape from the main surface; and the LED row is disposed such that each LED emits the ultraviolet ray toward the side surface of the light guiding plate. ### Claim 6 (depends on 1) The sterilizer according to claim 1, further comprising: a reflector that reflects the ultraviolet ray emitted by at least one LED of the LED row, toward a side surface of the radiographic imager. ### Claim 7 (depends on 1) The sterilizer according to claim 1, further comprising: a second LED row in which a plurality of LEDs that emit an ultraviolet ray are arranged in a row and which irradiates a back surface of the radiographic imager held by the holder with the ultraviolet ray emitted by each LED, the back surface being opposite to the radiation incident surface. ### Claim 8 (depends on 1) The sterilizer according to claim 1, further comprising: a hardware processor that calculates an intensity of energy received by the radiation incident surface when irradiated with the ultraviolet ray, based on at least one of a mode of irradiation of the radiation incident surface with the ultraviolet ray, an intensity of the ultraviolet ray emitted by each LED, and a range irradiated with the ultraviolet ray by each LED; and an energy notifier that notifies about the calculated intensity. ### Claim 9 (depends on 1) The sterilizer according to claim 1, further comprising: a hardware processor that calculates an intensity of energy received by the radiation incident surface when irradiated with the ultraviolet ray, based on at least one of a mode of irradiation of the radiation incident surface with the ultraviolet ray, an intensity of the ultraviolet ray emitted by each LED, and a range irradiated with the ultraviolet ray by each LED; and a corrector that performs correction such that the intensity of the energy received by the radiation incident surface is a predetermined intensity or more, when the calculated intensity is less than the predetermined intensity. ### Claim 10 (depends on 1) The sterilizer according to claim 1, further comprising: a hardware processor that stores a cumulative time for which each LED of the LED row emits the ultraviolet ray; and a time notifier that notifies about an indication of when the cumulative time is more than a predetermined time. ### Claim 11 (depends on 1) The sterilizer according to claim 1, further comprising: a hardware processor that measures an intensity of the ultraviolet ray emitted by each LED of the LED row; and an intensity notifier that notifies about an indication of when the intensity of the ultraviolet ray is less than a predetermined intensity. ### Claim 12 A sterilizer comprising: a holder that holds a portable radiographic imager; and an LED that emits an ultraviolet ray; and a device that causes an entirety of a radiation incident surface of the radiographic imager held by the holder, to be irradiated with the ultraviolet ray emitted by the LED. ### Claim 13 A mobile radiation irradiator configured to be movable, the irradiator comprising: a main body; a holder provided in the main body to hold a portable radiographic imager; an LED row in which a plurality of LEDs that emit an ultraviolet ray are arranged in a row and which irradiates a radiation incident surface of the radiographic imager with the ultraviolet ray emitted by each LED, the radiographic imager being held by the holder; and a radiation source that generates radiation.
