Abstract
Abstract A specimen holding device for microscope stages comprising a specimen supporting body secured to a microscope stage and a specimen push claw rotatably mounted on the specimen supporting body and urging a specimen against the specimen supporting body. The specimen supporting body and the specimen push claw are provided at respective front ends of the side edges thereof with inclined surfaces opposed with each other and inclined at an acute angle with respect to the specimen insertion direction and the distance between the front ends of the inclined surfaces is made sufficiently larger than the width of the specimen even when the specimen is not inserted between the specimen supporting body and the specimen push claw.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
A specimen holding device for a microscope stage, comprising: a specimen supporting body secured to the microscope stage; a specimen push claw rotatably mounted on said specimen supporting body, movable between an open and closed position, and biased toward said closed position; a three sided cavity having a base defined by said body, a first side, and a second side defined by said push claw; the end of said first side being provided with an outwardly inclined surface, completely nonrotatable with respect to said first side; the end of said push claw being provided with an outwardly inclined surface in the closed position, completely nonrotatable with respect to said push claw, said inclined surface defining an entrance to the cavity which narrows in width from the entrance toward the base, whereby a specimen moving towards said base can contact said inclined surfaces and cause said claw to rotate to an open position; wherein the edges of said first side and said push claw adjacent said cavity are downwardly inclined along their entire lengths to provide gripping means for gripping a specimen.
Claim 2
Dependent Claim
181 words
A specimen holding device for a microscope stage, comprising: a specimen supporting body secured to the microscope stage; a specimen push claw rotatably mounted on said specimen supporting body, movable between an open and closed position, and biased toward said closed position; a three sided cavity having a base defined by said body, a first side, and a second side defined by said push claw; the end of said first side being provided with an outwardly inclined surface, completely nonrotatable with respect to said first side; the end of said push claw being provided with an outwardly inclined surface in the closed position, completely nonrotatable with respect to said push claw, said inclined surface defining an entrance to the cavity which narrows in width from the entrance toward the base, whereby a specimen moving towards said base can contact said inclined surfaces and cause said claw to rotate to an open position; wherein the edges of said first side and said push claw adjacent said cavity are downwardly inclined along their entire lengths to provide gripping means for gripping a specimen.
Claim 3
Dependent Claim
25 words
A holding device as claimed in claim 1, wherein said body has an edge adjacent said cavity which is downwardly inclined along its entire length.
