Abstract
Abstract A sample applying position marking device for film for electrophoresis comprising a base having a frame which serves as reference surfaces, a top plate mounted to the base so that the top plate can be swung in respect to the base, and pointed protuberances mounted at pre-determined intervals on the bottom surface of the top plate. The sample applying position marking device is arranged to form marks at pre-determined positions of a film by means of the pointed protuberances mounted to the top plate when the film is placed on the base by matching the film to the frame and the top plate is swung downward.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
A sample applying position marking device for film for electrophoresis comprising a base having reference surfaces, a top plate arranged to move upward and downward on said base and to contact the top surface of said base when said top plate is moved downward, and pointed protuberances mounted to pre-determined positions on the surface of said top plate which contacts the top surface of said base when said top plate is moved downward, said sample applying position marking device for film for electrophoresis being arranged to form marks onto a film by placing the film on said base matching the film to said reference surfaces and by moving said top plate downward.
Claim 2
Dependent Claim
112 words
A sample applying position marking device for film for electrophoresis comprising a base having reference surfaces, a top plate arranged to move upward and downward on said base and to contact the top surface of said base when said top plate is moved downward, and pointed protuberances mounted to pre-determined positions on the surface of said top plate which contacts the top surface of said base when said top plate is moved downward, said sample applying position marking device for film for electrophoresis being arranged to form marks onto a film by placing the film on said base matching the film to said reference surfaces and by moving said top plate downward.
Claim 3
Dependent Claim
42 words
A sample applying position marking device for film for electrophoresis according to claim 1, in which said top plate is hinged to said base plate so that said top plate can be freely swung upward and downward in respect to said base.
Claim 4
Dependent Claim
31 words
A sample applying position marking device for film for electrophoresis according to claim 1, in which said pointed protuberances are mounted at pre-determined positions on the top surface of said base.
Claim 5
Dependent Claim
27 words
A sample applying position marking device for film for electrophoresis according to claim 1, in which said reference surfaces of said base are arranged to be movable.
Claim 6
Dependent Claim
120 words
A sample applying position marking device for film for electrophoresis comprising a base, a slide having reference surfaces and slidably mounted to said base, a top plate arranged to move upward and downward on said slide and to contact the top surface of said slide when said top plate is moved downward, and pointed protuberances mounted to pre-determined positions on the surface of said top plate which contacts the top surface of said slide when said top plate is moved downward, said sample applying position marking device for film for electrophoresis being arranged to form marks onto a film by placing the film on said slide matching the film to said reference surfaces and by moving said top plate downward.
Claim 7
Dependent Claim
120 words
A sample applying position marking device for film for electrophoresis comprising a base, a slide having reference surfaces and slidably mounted to said base, a top plate arranged to move upward and downward on said slide and to contact the top surface of said slide when said top plate is moved downward, and pointed protuberances mounted to pre-determined positions on the surface of said top plate which contacts the top surface of said slide when said top plate is moved downward, said sample applying position marking device for film for electrophoresis being arranged to form marks onto a film by placing the film on said slide matching the film to said reference surfaces and by moving said top plate downward.
Claim 8
Dependent Claim
31 words
