PROBLEM TO BE SOLVED: To provide a high temperature compensation function and to keep a high temperature compensation function after being placed in a low temperature by dividing a temperature compensation member fixed to the frame of a color selecting mechanism and having a coefficient of thermal expansion larger than that of the frame into plural pieces. SOLUTION: An STC plate 8, fixed to a frame of a color selecting mechanism, is divided into a first STC plate 8a and a second STC plate 8B. These two STC plates 8A, 8B are welded to an elasticity giving member 6b, at a welding point 9 installed at an end (an outer end part) on a side opposite to a facing end. A guide plate 20 is installed at the facing end of the STC plates 8a, 8b divide so as to wrap the end and is fixed to the side of the elasticity giving part 6b at a welding point 21. The guide plate 20 prevents slippage or floating up of the STC plates 8A, 8B.
