Claims

[Claims for Utility Model Registration] 1. In a camera finder device for observing a subject image formed on a focusing plate having a focal plane at a position optically equivalent to the film plane through a pentaprism, the focusing plate;
A holding part that holds the pentaprism from below; a first positioning surface that is the lower surface of the holding part and that abuts the focal plane of the reticle for positioning; and a first positioning surface that is on the same plane as the first positioning surface. a second positioning surface for positioning the pentaprism holding member at a position optically equivalent to the film surface by contacting the supporting surface of the camera body, which is positioned at a position optically equivalent to the film surface; A finder device comprising: 2 The pentaprism holding member is a pentaprism,
It has abutting means that comes into contact with both sides to obtain a force that elastically deforms the pentaprism holding member upwardly, and further includes a holding member that holds the pentaprism from above, and connects the holding member and the pentaprism holding member. 2. The finder device according to claim 1, further comprising a fastening means for forcing the holding portion of the pentaprism holding member along the lower surface of the pentaprism against the force.
