Abstract
Abstract A document holder including a vertically shiftable support platform, a clamping arm overlying the platform, and springs yieldably urging the platform and arm toward each other. The clamping arm is shiftable laterally of the platform. Operator mechanism engaged by the platform when it is depressed shifts the arm laterally of the platform for insertion of a document. When the platform shifts back to its raised position the arm moves back over the platform to grip the document.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
113 words
A document holder, in an upright position comprising a vertically shiftable support platform having an upper document support surface, clamping means including a clamping portion mounted for movement between a first position overlying said surface intermediate the center and an edge of the platform and a second position spaced laterally outwardly from said first position in a direction away from the center of the platform, biasing means yieldably urging said platform and clamping means toward each other for gripping a document therebetween, and operator means operatively connected to said clamping means for moving the same relative to the platform from its first toward its second position simultaneous with the depression of the platform.
Claim 2
Dependent Claim
113 words
A document holder, in an upright position comprising a vertically shiftable support platform having an upper document support surface, clamping means including a clamping portion mounted for movement between a first position overlying said surface intermediate the center and an edge of the platform and a second position spaced laterally outwardly from said first position in a direction away from the center of the platform, biasing means yieldably urging said platform and clamping means toward each other for gripping a document therebetween, and operator means operatively connected to said clamping means for moving the same relative to the platform from its first toward its second position simultaneous with the depression of the platform.
Claim 3
Dependent Claim
24 words
The holder of claim 1, wherein said clamping portion comprises an arm mounted for swinging about an axis disposed laterally outwardly of said platform.
Claim 4
Dependent Claim
