PROBLEM TO BE SOLVED: To prevent a grid from falling down by erroneous operations in grid attaching and detaching operations or by carelessness during an operation. SOLUTION: A fixing pin 23 for fixing the grid 6 is provided in a right upper part of a photographing device 1, and is engaged with an engaging hole 14 provided in a grid holding part 13 to fix the grid 6 in the first position. The other end of the fixing pin 23 is exposed from a casing 3 to its outside, and forms a release lever 24. When the release lever 24 is slide-moved along a direction of an arrow mark, the fixing pin 23 is pushed up to a position B against energizing force by an energizing means to release the fixing of the grid 6. When the grid 6 is taken out from the photographing device 1, the fixing of the grid 6 is released to be extracted by a distance L, the fixing pin 23 is thereby engaged with another one engaging hole 15 by action of the energizing means, and the grid 6 is fixed to the second position. When the grid 6 is removed completely from the photographing device 1, the release lever 24 is operated to release the fixing so as to pull out the grid 6. COPYRIGHT: (C)2003,JPO
