Abstract
An apparatus for removing dust from a photographic film is disclosed. The apparatus includes cylindrical rotatable dust removing members disposed upwardly and downwardly of the film, and a dust take-off member disposed adjacent the dust removing members for taking off the dust from the dust removing members. The dust removing members may be brush members or members having an adhesive face. Further, these dust removing members may be adapted to be movable between a dust removing position and a non dust removing position.
Claims13
A dust removing apparatus for removing dust from a sheet-like photosensitive material transported along a transport passage, comprising:
- a stationary portion;
- dust removing means movable relative to the stationary portion for removing dust from said sheet-like photosensitive material, said dust removing means comprising a first dust removing member having a cylindrical shape and comprising a first dust removing brush surface that contacts a front surface of said sheet-like photosensitive material and a second dust removing member having a cylindrical shape and comprising a second dust removing brush surface that contacts a back surface of said sheet-like photosensitive material;
- and
- dust take-off means having an adhesive surface which comes into contact with said first and second dust removing brush surfaces for taking the dust therefrom by adhesion thereto.
A dust removing apparatus for removing dust from a sheet-like photosensitive material transported along a transport passage, comprising:
- a stationary portion;
- dust removing means movable relative to said stationary portion for removing dust from said sheet-like photosensitive material, said dust removing means comprising a first dust removing member having a first dust removing surface that contacts said sheet-like photosensitive material, and a second dust removing member having a second dust removing surface that contacts said sheet-like photosensitive material;
- and
- dust take-off means having an adhesive surface which comes into contact with said first and second dust removing surfaces for taking the dust therefrom by adhesion thereto,
- wherein the second dust removing member is disposed adjacent the first dust removing member, the first dust removing surface of the first dust removing member extends discontinuously in the direction of the rotary axis of the first dust removing member, the second dust removing surface of the second dust removing member extends discontinuously in the direction of the rotary axis, and the first dust removing surface of the first dust removing member and the second dust removing surface of the second dust removing member are disposed alternately to each other in the direction of the rotary axis.
A dust removing apparatus for removing dust from a sheet-like photosensitive material transported along a transport passage, comprising
- dust removing means comprising a first dust removing member having a first dust removing surface that contacts a front surface of said sheet-like photosensitive material, and a second dust removing member having a second dust removing surface that contacts a back surface of said sheet-like photosensitive material, said first and second dust removing members being positioned such that said first dust removing member cooperates with said second dust removing member to hold said sheet-like photosensitive material therebetween;
- dust take-off means having an adhesive face which comes into contact with the first and second dust removing surfaces to take the dust off the first and second dust removing surfaces by adhesion thereto;
- and
- actuating means connected to at least one of said first and second dust removing surfaces for moving said at least one of said first and second dust removing surfaces between a first position where said at least one of said first and second dust removing surfaces is away from said sheet-like photosensitive material and a second position where said first and second dust removing surfaces cooperate to remove dust from said sheet-like photosensitive material.
A dust removing apparatus for removing dust from a sheet-like photosensitive material transported along a transport passage comprising:
- a stationary portion;
- dust removing means movable relative to the stationary portion and having a dust removing portion for coming into contact with the sheet-like material;
- and
- dust take-off means having an adhesive face which comes into contact with the dust removing portion to take the dust off the dust removing portion by adhesion thereto;
- wherein the dust removing portion is formed of urethane cloth.
A dust removing apparatus for removing dust from a sheet-like photosensitive material transported along a transport passage in a transporting direction, comprising
- a stationary portion;
- and
- dust removing means movable relative to the stationary portion for removing dust from said sheet-like photosensitive material, said dust removing means comprising a first surface and an auxiliary adhesive surface positioned laterally of said first surface with respect to said transporting direction, said auxiliary adhesive surface having a greater adhesive power than said first surface.
