<P>PROBLEM TO BE SOLVED: To provide a case for a mark sheet configured so that a sheet can be surely put at a predetermined position in the case only by simply inserting it from a sheet insert opening without special attention, and a writing area of the sheet can be thus surely matched to a writing opening of the case. <P>SOLUTION: The case is constituted by mutually fitting a surface plate 1 with a writing opening corresponding to each writing area of a mark sheet and a reverse plate 2. The surface plate 1 and the reverse plate 2 include engagement structures 6, 7 disposed on three peripheral portions other than the side with the sheet insert opening formed therein. The inner side of the engagement structure 7 formed on the reverse plate 2 is raised to form a frame wall 8 for securing the sheet insert opening and a sheet housing portion 4, and a groove 10 in which an upper portion of the frame wall 8 is inserted is formed on the peripheral portion of a top inner surface 9 of the surface plate 1 on which the upper surface of the frame wall 8 abuts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
