X-ray detector holder stand

An X-ray detector holder stand comprising:

• a base supported on a floor;
• a post provided upright on the base;
• an arm extending horizontally to be guided in a top-bottom direction along the post;
• and
• a holder coupled to a distal end of the arm,
• wherein the arm comprises:
• an extension block having a plate surface extending horizontally, with an LM guide being fastened integrally to the plate surface;
• and
• an end block fitted on the extension block through a rear end, wherein the holder is coupled to a front end of the end block to be rotatable in top-bottom and right-left directions and an LM guide block is slidably coupled to the LM guide and is fastened integrally to a plate surface of the end block, such that the end block is extensible from and contractible to the extension block.

An X-ray detector holder stand comprising:

• a base supported on a floor;
• a post provided upright on the base;
• an arm extending horizontally to be guided in a top-bottom direction along the post;
• and
• a holder coupled to a distal end of the arm,
• wherein the holder is configured to be pivoted in the top-bottom direction by a vertical pivot unit disposed between the holder and a distal end of the arm, and
• wherein the vertical pivot unit comprises:
• a fixing element supporting a fixing pin extending horizontally;
• a pivot element coupled to the fixing pin to be pivotable in a top-bottom direction so as to pivot between a horizontal angel at which the pivot element is located above the fixing element and a vertical angle located in front of the fixing element;
• an elastic element axially coupled to the fixing pin, with one end of the elastic element being supported by the fixing element and the other end of the elastic element elastically pressing the pivot element at the horizontal angle;
• and
• a pivot angle fixing means for fixing an angle of pivot of the pivot element with respect to the fixing element.
