<p>Disclosed is an X-ray imaging device with which an operator can readily and reliably recognize the type of add-on filter that is selected. An add-on filter is selected in accordance with the rotation of a rotary plate (11) caused by a motor (12). The information of the selected add-on filter is sent to a controller (41). The controller (41) drives a motor (22) on the basis of information of the selected add-on filter, and any one of a plurality of colour filters is moved into the optical path from a light source (24) to a patient (1) by rotating a second rotary plate (21) in accordance with the selected add-on filter. As a result, the colour of the light rays of the light field becomes a colour corresponding to the selected add-on filter.</p> |
