Abstract
An X-ray radiographing apparatus is provided with an interlock mechanism to avoid mutual interference of movable elements such as an X-ray unit, a compression cone, a table, a tabletop and a spot-film device. When a judging element judges, in response to information outputted from a position detecting element of the movable elements and switches operated by an operator, that interlock should be done, an interlocking element is worked, and then a teaching unit is worked. Thus, the interlocked state itself and how to unlock from the interlocked state can be taught to the operator with graphic images by the teaching unit.
Claims13
An X-ray radiographing apparatus in which at least one movable element is disposed to be moved for X-ray radiographing in response to commands from a switch means used by an operator, said X-ray radiographing apparatus comprising:
- means for detecting positions of said movable element;
- means for judging whether or not said movable element is positioned in a predetermined interlock range in response to signals from said switch means and said detecting means;
- means for interlocking said movable element when judgement by said judging means shows that said movable element is positioned in the interlock range;
- means for teaching the operator an interlocked state of the movable element and how to unlock the interlocked state with graphic images, when said interlocking means begins working.
