Abstract
Abstract Apparatus for making photographic records of dental study models comprising a frame, a multiple exposure camera adjustably connected to the frame, and supporting means on the frame spaced from the camera and including a plurality of supporting elements in the form of horizontally disposed shelf members arranged in spaced relation along a surface in the field of view of the camera. A plurality of different photographic views of a study model can be made on a single photographic record member such as a film or plate by placing the model successively in different orientations on the supporting shelf members and taking corresponding successive exposures with the camera.

Claim 1
Independent Claim
216 words
Apparatus for making photographic records of three dimensional dental study models comprising: a. frame means; b. a multiple exposure camera connected to said frame means; c. supporting means on said frame means and spaced from said camera, said supporting means comprising a planar background element disposed in a plane perpendicular to the optical axis of said camera and a plurality of supporting elements on said background element arranged in a plurality of rows spaced along the surface of said element facing said camera in the field of view of said camera, there being at least one supporting element in each of said rows, each supporting element being adapted to hold a three dimensional study model manually placed thereon and to hold a three dimensional study model in different orientations thereon; and d. adjustable means connecting said camera to said frame means in a manner allowing selective movement of said camera in a direction generally parallel to the plane of said background element and from row to row relative to said supporting elements; e. whereby a plurality of different photographic views of a study model are made on a single photographic record member by manually placing the model successively in different orientations on successive ones of said supporting elements and taking corresponding successive exposures with said camera.
