Camera positioning apparatus
First Claim
1. In picture taking apparatus,(a) at least one element for varying the distance between a part of a camera and an object to be photographed,(b) a track for supporting said element for movement to thus enable said distance to be varied,(c) means for moving said element along said track to change the relative position of said part of the camera and the object to be photographed,(d) incremental locating means mounted on said track for defining a series of locations along said track, and(e) reciprocating means carried by said element for engaging and disengaging said incremental locating means to position said reciprocating means in a selected one of said series of locations along said track,the improvement comprising:
- means, including carriage means, mounting said reciprocating means on said element to permit relative movement between said reciprocating means and said element parallel to said track, so that relative movement parallel to said track may occur between the element and the reciprocating means when the reciprocating means has engaged the incremental means and the element is moved parallel to the track and with respect to the incremental location means, said reciprocating means being mounted to reciprocate in said carriage means for engaging and disengaging said incremental locating means, anda distance indicating gauge carried by said element in fixed relationship thereto and having an actuating projection extending therefrom for engaging said carriage means, so that when said element moves relative to said reciprocating means the amount of such movement will be indicated by said gauge,whereby the engagement of the reciprocating means with the incremental means achieves a relatively coarse position of said element and the reading of said gauge is a relatively fine indication of the position of the element with respect to one of said locations.

Abstract
A picture taking apparatus is provided which accurately positions a camera lens with respect to the object being photographed. The apparatus comprises in part an element which is supported on and moves along a track. The track has equally spaced parallel pins extending in one direction therefrom and complementary indicator marks located on one face thereof. The element has a carriage which slides horizontally along a shaft of the element which is parallel to the track. The carriage has a cam-operated plate which slides vertically in said carriage to engage and disengage said pins. When the cam-operated plate engages a pin, the carriage is "fixed". This provides a "coarse" adjustment for the position of the camera lens. For the "fine" adjustment, the element is still free to move along the track. The element can be moved along the track to "fine tune" the position of the camera with respect to the object to be photographed. The exact position of the camera lens carried by the element is determined by a gauge which is fixably attached to the element. The gauge has an actuating projection which runs between the element and the carriage so that the precise distance the element is moved with respect to the fixed carriage can be determined.
