Abstract: The sample imaging apparatus includes: a housing that forms a closed space; a transparent tray on which a sample is placed in the housing; a plane light source that is formed by using a flat light guide plate, which propagates light emitted by a light emitting element in a plane direction, so as to illuminates the sample with illumination light through the tray in the housing; a lens that is disposed in the housing so as to face the plane light source with the tray interposed between the lens and the plane light source and is used for imaging the sample; and an imaging control unit that adjusts a focal length of the lens and performs imaging in a case of imaging the single sample.

Abstract: A feed mechanism, which is capable of suppressing feed irregularity caused by the inclination of a nut of a feed screw, is obtained. A feed mechanism (sub-scanning mechanism) includes a feed screw that includes a screw shaft and a nut and a moving body, and the nut is moved on the screw shaft by a rotation of the screw shaft, so that the moving body is moved in the direction of the screw shaft. The inclination of the moving body with respect to the nut is allowed in a case in which the moving body is moved by a movement of the nut.

Abstract: A mammography apparatus includes: an arm; a first cooling fan that is disposed on a stand side with respect to the radiation source in the arm, sucks air from an outside of the arm, and discharges air that has cooled the radiation source from a first exhaust port provided on the stand side with respect to the radiation source; a projector that is disposed in the arm; a second cooling fan that is disposed between the projector and the first exhaust port in the arm, sucks a part of air directed from the first cooling fan to the first exhaust port, blows the sucked air toward the projector to cool the projector, and has a flow rate smaller than that of the first cooling fan; and a second exhaust port that is provided separately from the first exhaust port and through which air that has cooled the projector is discharged.

Abstract: In the radiographic imaging device, a portion of a second effective imaging region at a first side or a second side of a sensor unit of a second radiation detection panel, and a portion of a first effective imaging region at a third side or a fourth side of the sensor unit of a first radiation detection panel, are overlapped in a radiation irradiating direction. A portion of a second effective imaging region at the third side or the fourth side of the sensor unit of the second radiation detection panel, and a portion of a third effective imaging region at the third side or the fourth side of the sensor unit of the third radiation detection panel, are overlapped in the radiation irradiating direction. The second radiation detection panel is disposed at a side opposite the radiation irradiating section side of the first radiation detection panel and the third radiation detection panel.
