Abstract
According to the present invention, a film which has been inserted into a film insertion opening of a support is conveyed toward the inner part reciprocatably by a conveyance means; light is emitted from a light source and is allowed to pass through the film being conveyed; the light which has passed through the film is refracted along the film conveying direction by a refractor; and the light thus refracted by the refractor is received by an optical reader, which reads an image formed on the film. This construction permits the reduction in size of the entire apparatus.
Claims9
An image scanner for film, comprising:
- a support having a film insertion opening;
- a conveyance means, including a movable member which is movable reciprocatably between the film insertion opening and an inner portion of said support, for conveying a film which has been inserted into the film insertion opening;
- a light source for radiating light to the film being conveyed by said conveyance means, in a direction perpendicular to the film conveying direction;
- a refractor for refracting the light which has been emitted from said light source and passed through the film, along the film conveying direction;
- and
- an optical reader for receiving the light refracted by said refractor and reading an image formed on the film,
- wherein said conveyance means includes a holder portion which comprises a receptacle portion formed therein to support the peripheral edges of the film, a first plate spring attached at one end thereof to said movable member so as to be capable of rising and falling, and a pair of second plate springs, each having a first and second end, wherein said first end is attached to said first plate spring through an elastic member and said second end is formed into a flat pressing surface which resiliently contacts said receptacle portion.
An image scanner for film, comprising:
- a support having a film insertion opening;
- a movable member capable of reciprocating from the film insertion opening toward an inner portion of said support, said movable member having a holder portion for removably holding the film which has been inserted into the film insertion opening;
- a light source for radiating light to the film being conveyed by said movable member, in a direction perpendicular to the film conveying direction;
- a refractor for refracting the light which has been emitted from said light source and passed through the film, along the film conveying direction;
- and
- an optical reader for receiving the light refracted by said refractor and reading an image formed on the film,
- wherein the holder portion said movable member comprises a receptacle portion formed in the movable member to support the peripheral edges of the film, a first plate spring attached at one end thereof to said movable member so as to be capable of rising and falling, and a pair of second plate springs, each having a first and second end, wherein said first end is attached to said first plate spring through an elastic member and said second end is formed into a flat pressing surface which resiliently contacts said receptacle portion.
