<p><P>PROBLEM TO BE SOLVED: To prevent a transmission mechanism which transmits power for moving a grid to the grid from interfering with a grid retreating operation. <P>SOLUTION: A radiographic apparatus includes: a grid arranged at a first position between a mounting surface and a radiation detector, to prevent scattered components of radiation generated by transmission of the radiation to a breast from being made incident on the radiation detector; a retreating mechanism for retreating the grid from the first position to a second position toward the front of a subject such that the grid is separated from the subject facing an imaging stand; a power generation mechanism for generating power for moving the grid along the left-right direction of the subject; and a transmission mechanism coupled with the power generation mechanism to transmit the power from the power generation mechanism to the grid at the first position, and separated from the power generation mechanism along with the retreating operation of the grid to prevent transmission of the power from the power generation mechanism to the grid at the second position. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
