Abstract
PURPOSE:To surely indicate numbers of remaining frames of a film with a simple constitution, by providing an information member which indicates the number of remaining frames of the film which can be used for taking picture, and which is coupled with the rotation of a rotary body which rotates when the film is advanced. CONSTITUTION:A roller 36 is constituted in such a way that a part of its inner surface is frictionally engaged with the surface of a film 22 through an opening facing to the film 22 so that the roller may rotate as the film 22 advances, and one revolution of the roller 36 coincides with an advanced amount of one frame of the film 22. Moreover, an inverted gear 43 which functions as an information member is installed to the bottom plate of a bottom cover 20 of a film feeding section 14, so that it may rotate, and an information disk 44 is fitted to the bottom. When such constitution is applied, the advanced amount of one frame of the film 22 becomes constant, and, therefore, a constant advancement of the film can be achieved and, at the same time, the number of remaining frames of the film is indicated correctly.
