PURPOSE:To contrive the reduction of cost, and also, to clearly observe the rotating state of a display member by constituting the whole display member of an integral formed part, so that a column part extending in the direction orthogonal to the rotating direction can also be formed simultaneously. CONSTITUTION:In this case, a window member 38 consists of three parts 40, 42 and 44, and in the upper stage and the lower stage of the window member 38, the thickness of an interval of column parts 28, 30, 32 and 34 are seen so as to be widened by the operation of a prism, and in the middle stage of the window member 38, the thickness and the interval of the column parts 28, 30, 32 and 34 are seen so as to be narrowed by the operation of the prism. By this difference, a photographer can observe exactly a fact that a sprocket 20 is rotating, that it, a fact that a film F is being fed. Also, a display member 22 is constituted by forming plastic integrally, and can be manufactured easily.
