Abstract
An exposure slit for an image recording apparatus comprises a plate having an opening for the passage of light. First and second inclined walls extend toward each other from the plate to form a slit over the opening. The inclined walls form a light trap which reduces the occurrence of fogging in the image recorder.
Claims26
An exposure slit for use with a light sensitive image recording medium, the exposure slit comprising:
- a plate having an opening in a planar surface thereof;
- and
- first and second inclined walls extending toward each other and away from the planar surface of said plate and toward said recording medium to form a slit over said opening, said first and second inclined walls adapted to divert light reflected from the image recording medium away from the image recording medium to reduce fogging of the image recording medium during exposure thereof.
An image recording apparatus for exposing a light sensitive recording medium with radiation from an imaging source, the apparatus comprising:
- a plate having an elongated opening in a planar surface thereof arranged in proximity to said recording medium;
- and
- first and second inclined walls extending toward each other and away from the planar surface of said plate toward said recording medium to form a slit over said opening, said first and second inclined walls adapted to divert radiation reflected from the recording medium away from the recording medium.
A plate having an opening in a planar surface thereof for use with a light sensitive image recording medium, said plate comprising:
- first and second inclined walls extending toward each other and away from the planar surface of said plate to form a slit over said opening, said first and second inclined walls adapted to divert light reflected from the image recording medium away from the image recording medium to reduce fogging of the image recording medium during exposure thereof;
- said plate being adapted for movement along a portion of said recording medium with said exposure slit adjacent to said portion and said inclined walls extending toward said portion.
