PROBLEM TO BE SOLVED: To provide a camera which surely switches visual field ranges of a viewfinder and marks indicating print sizes by a simple, low-cost structure. SOLUTION: With the movement of a changeover knob 15 to three set positions, a visual field switching mechanism 21 and a mark switching mechanism 31 are switched through individual flexure arms 42 and 43. In the middle of the movement of the changeover knob 15 to the set positions at both ends, projections 26b and 27b abut against end parts of guide slots 23b and 23c, and 24b and 24c and a mark witching plate 34 abuts against stoppers 33e and 33f. Further, the changeover knob 15 is moved in an overstroke state toward the set positions at both the ends and then the flexure arms 42 and 43 are made to flex to press the guide slots 23b and 23c, and 24b and 24c against the projections 26b and 27b ad the mark switching plate 34 against the stoppers 33e and 33f. At the respective set positions, a click projection 46 engages with click grooves 47 and 49.
