Abstract

A cassette to record a radiation image of an object to be radiographed, is provided with a sheet-shaped recording medium including a layer of needle imaging plate having a thickness of 20 μm to 2 mm, wherein the needle imaging plate are formed by a deposition method; a front member through which the recording medium receives the radiation image of the object; and a back member positioned opposite to the front member; wherein the front and back members are relatively attached to each other so as to form an accommodation space in which the sheet-shaped recording medium is accommodated or detached from each other and the attaching or detaching direction of the front and back members is substantially the same direction with a growing direction of the needle imaging plate.

1 . A cassette to detect a radiation image of an object, comprising: 
 a sheet-shaped detecting medium including a needle imaging plate layer which has a thickness of 20 μm to 2 mm and which is formed by deposition;    a front member through which the detecting medium receives the radiation image of the object;    a back member positioned opposite to the front member;    a base member protruding from the back member, wherein the sheet-shaped detecting medium is placed at a joining position on the base member; and    a joining member provided at the joining position so as to join the sheet-shaped detecting medium and the base member such that the sheet-shaped detecting medium and the base member move relative to each other when the back member deforms.    
   
   
       2 . The cassette of  claim 1 , wherein the joining member comprises one of a magnet, an elastic adhesive agent and a double-sided adhesive tape.  
   
   
       3 . The cassette of  claim 2 , wherein the base member comprises a first base member to form a first joining position and a second base member to form a second joining position, and wherein one of the elastic adhesive agent and the double-sided adhesive tape is provided at the first joining position and the magnet is provided at the second joining position.  
   
   
       4 . The cassette of  claim 2 , wherein the joining member comprises the magnet and an iron member and when the back member deforms, the magnet and the iron member move with respect to each other from a line contact to a point contact.  
   
   
       5 . The cassette of  claim 2 , further comprising a position regulator to regulate a position of the sheet-shaped detecting medium.
