Abstract

Abstract A film peeling apparatus for peeling off a film stuck onto a base by raising one end thereof comprises a projection-formed detecting member for detecting the end of said film stuck onto said base and an oscillating device for oscillating said projection-formed detecting member upon detection of the end of film by said detecting member to thereby raise the end of said film.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 64 words
A film peeling apparatus for peeling off a film stuck onto a base by raising one end thereof, comprising a projection-formed detecting member for detecting the end of said film stuck onto said base and an oscillating device for oscillating said projection-formed detecting member upon detection of the end of the film by the detecting member to thereby raise the end of said film.
Claim 2
Dependent Claim 64 words
A film peeling apparatus for peeling off a film stuck onto a base by raising one end thereof, comprising a projection-formed detecting member for detecting the end of said film stuck onto said base and an oscillating device for oscillating said projection-formed detecting member upon detection of the end of the film by the detecting member to thereby raise the end of said film.
Claim 3
Dependent Claim 93 words
A film peeling apparatus for peeling off a film stuck onto a base, said film peeling apparatus comprising a projection-formed detecting member for detecting the end of said film stuck onto said base, an oscillating device for oscillating said projected detecting member upon detection of the end of the film by said detecting member to thereby raise the end of said film, and a fluid injection device for peeling said film off from said base by injecting a jet of fluid to the end of said film thus raised by said detecting device.
Claim 4
Dependent Claim 93 words
A film peeling apparatus for peeling off a film stuck onto a base, said film peeling apparatus comprising a projection-formed detecting member for detecting the end of said film stuck onto said base, an oscillating device for oscillating said projected detecting member upon detection of the end of the film by said detecting member to thereby raise the end of said film, and a fluid injection device for peeling said film off from said base by injecting a jet of fluid to the end of said film thus raised by said detecting device.
Claim 5
Dependent Claim 30 words
A film peeling apparatus of claim 2, wherein said fluid injection device comprises a nozzle member for injecting fluid and wherein said projection-formed detecting member oscillates inside said nozzle member.
Claim 6
Dependent Claim 71 words
A film end raising device, applicable to a film peeling apparatus, for raising one end of a film stuck onto a base, comprising a projection-formed detecting member for detecting the end of said film stuck onto the base and an oscillating device for oscillating said projection-formed detecting member upon detection of the end of the film by said detecting member to thereby raise the end of said film from the base.
Claim 7
Dependent Claim 71 words
A film end raising device, applicable to a film peeling apparatus, for raising one end of a film stuck onto a base, comprising a projection-formed detecting member for detecting the end of said film stuck onto the base and an oscillating device for oscillating said projection-formed detecting member upon detection of the end of the film by said detecting member to thereby raise the end of said film from the base.
