Abstract
Abstract A reader for a digital code matrix carried on a film having a scanning bar with a plurality of photo detectors is mounted on a frame. The frame is rectangular in shape and pivotally connected on each corner so that it can assume the shape of a parallelogram. This is necessary since the code matrix is quite often photographically deposited on the film when it is moving or not flat so that rectangular code pattern is skewed. The scanning bar is motor driven. The photo detectors are connected to suitable utilization apparatus. A variant of this arrangement uses sensors which are fixed and the image is moved over the sensors.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A reader for a rectangular code matrix carried on a film comprising a frame adapted to be mounted to receive an image from said film, means in said frame to receive an image of said matrix, and bar means mounted on said frame to scan said image and a plurality of detectors mounted on said bar means, said bar means extending across said frame and said detectors being longitudinally spaced along said bar means so that each detection will read one line of said matrix, wherein said frame is constructed of four sides which are pivotally connected together at their ends so that said frame can assume a parallelogram shape and means connected to adjust the shape of said frame.
Claim 2
Dependent Claim
120 words
A reader for a rectangular code matrix carried on a film comprising a frame adapted to be mounted to receive an image from said film, means in said frame to receive an image of said matrix, and bar means mounted on said frame to scan said image and a plurality of detectors mounted on said bar means, said bar means extending across said frame and said detectors being longitudinally spaced along said bar means so that each detection will read one line of said matrix, wherein said frame is constructed of four sides which are pivotally connected together at their ends so that said frame can assume a parallelogram shape and means connected to adjust the shape of said frame.
Claim 3
Dependent Claim
39 words
Apparatus as in claim 1 comprising motor means, a pair of lead screws rotatably mounted one each on opposite side of said frame and connected to said motor means and means connecting said scanning bar to said lead screws.
Claim 4
Dependent Claim
25 words
Apparatus as in claim 2 wherein one end of said lead screws is each connected to a universal-type bearing to permit movement of said frame.
Claim 5
Dependent Claim
16 words
Apparatus as in claim 1 having screw-type adjustment means to adjust the shape of said frame.
Claim 6
Dependent Claim
62 words
A reader for a code matrix carried on a film comprising, a frame adapted to be mounted to receive an image from said film, a plurality of sensors adjustably mounted in said frame, and means to scan said image over said sensors wherein said frame has a viewing screen and said sensors are rotatably and adjustably mounted to accommodate a skewed image.
Claim 7
Dependent Claim
62 words
A reader for a code matrix carried on a film comprising, a frame adapted to be mounted to receive an image from said film, a plurality of sensors adjustably mounted in said frame, and means to scan said image over said sensors wherein said frame has a viewing screen and said sensors are rotatably and adjustably mounted to accommodate a skewed image.
Claim 8
Dependent Claim
18 words
Apparatus as in claim 5 wherein said sensors are adjustable in position along the width of said image.
