Abstract

Abstract A chemical analysis slide frame assembly including first and second slide frames each having an opening whose area is smaller than the area of a chemical analysis film inserted therein and a third slide frame disposed between the first and second slide frames. The third slide frame has an opening which is adapted to receive the chemical analysis film and is shaped so as to substantially prevent the displacement of the chemical analysis film. The third slide frame has a thickness which is equal to or larger than the thickness of the chemical analysis film. The side wall of the opening in the first slide frame has a small optical reflection factor, preferably is dark so as to provide a small optical reflection factor.

Claim 3
Dependent Claim 33 words
The assembly as set forth in claim 1 in which said side wall of the opening in said first slide frame is made dark so as to provide a small optical reflection factor.
Claim 4
Dependent Claim 22 words
The assembly as set forth in claim 1 in which said first and third slide frames are formed as a single unit.
Claim 5
Dependent Claim 22 words
The assembly as set forth in claim 1 in which said second and third slide frames are formed as a single unit.
Claim 6
Dependent Claim 36 words
The assembly as set forth in any one of claims 1 to 4 in which the surface of said first slide frame which is farther from said second slide frame has a small optical reflection factor.
Claim 7
Dependent Claim 42 words
The assembly as set forth in any one of claims 1 to 4 in which the surface of said first slide frame which is farther from said second slide frame is made dark so as to provide a small optical reflection factor.
Claim 8
Dependent Claim 70 words
The assembly as set forth in any one of claims 1 to 4 in which the side wall of the opening in said first slide frame is an inclined side wall, and one end face of said inclined side wall which is closer to said second slide frame is larger in size than the other end face of said inclined side wall which is farther from said second slide frame.
Claim 9
Dependent Claim 32 words
The assembly as set forth in any one of claims 1 to 4 in which the opening of said first slide frame is smaller than the opening of said second slide frame.
Claim 10
Dependent Claim 34 words

Claim 12
Dependent Claim 43 words
The assembly as set forth in claim 7 in which the end face of the opening in said first slide frame which is farther from said second slide frame has the same configuration and size as the opening of said second slide frame.
Claim 13
Dependent Claim 42 words
The assembly as set forth in claim 1 or 2 in which a code indicating the kind of a chemical analysis film inserted therein is marked on the surface of said second slide frame which is farther from said first slide frame.
Claim 14
Dependent Claim 22 words
The assembly as set forth in claim 12 in which said code is at least one of a protrusion and a recess.
Claim 15
Dependent Claim 40 words
