Abstract: A scanning device includes an MEMS mirror mechanism that swings a mirror with respect to a first axial line as a central line and swings the mirror with respect to a second axial line as a central line, and a control unit that generates a first drive signal for swinging the mirror with respect to the first axial line, and a second drive signal for swinging the mirror with respect to the second axial line. The control unit generates the first drive signal and the second drive signal so that m times of reciprocation of an irradiation region in a first direction and one time of reciprocation of the irradiation region in a second direction correspond to each other by repeating generation of a second signal element constituting the second drive signal to correspond to a first signal element in a period equal to or less than one cycle in the first drive signal.

Abstract: A radiation image detecting device includes a photodetecting element that detects fluorescence light, and a prism that is disposed on an optical path of excitation light traveling toward an imaging plate and between the photodetecting element and the imaging plate. The prism includes, as surface thereof, a side face that is opposed to the imaging plate, and a side face and a side face that are inclined relative to the side face. The prism is disposed so that the excitation light incident through the side face propagates inside and is output from the side face and so that reflection from the imaging plate incident through the side face propagates inside and is output from the side face. The photodetecting element is disposed so as to be opposed to a region different from a region where the reflection from the imaging plate is output, in the surface of the prism.

Abstract: A scanning device includes an MEMS mirror mechanism that swings a mirror with respect to a first axial line as a central line and swings the mirror with respect to a second axial line as a central line, and a control unit that generates a first drive signal for swinging the mirror with respect to the first axial line as a central line and a second drive signal for swinging the mirror with respect to the second axial line as a central line. In a lighting-on period in which a light source emits laser light in one swing of the mirror with respect to the second axial line as a central line, the control unit generates the first drive signal and the second drive signal by repeating a process of generating N pieces (N is an integer of two or greater) of second signal elements which respectively constitute the second drive signal with respect to a first signal element in a ½ cycle period in the first drive signal.
