Claims

[Scope of utility model registration request]

(1) A boundary line extraction imaging exposure device for extracting density conversion points of a continuous tone image and converting it into a line drawing, which is capable of placing an original photograph and rotating it within the plane of the original photograph. a pedestal, a light source unit that generates a linear light beam that is incident at an angle of 45 degrees from both left and right directions with respect to the plane of the original photograph, and a light source that supports the light source unit so that it can be moved back and forth along the plane of the original document. A boundary line extraction imaging exposure apparatus comprising: a scanning mount; and a control section for rotating the original photographic mount by a predetermined angle each time the light source section scans a plane of the original.

(2) The light source section includes a light box having slits in the left and right directions of 45 degrees, a fluorescent lamp arranged inside the light box, and a columnar lens for converting the light flux from each of the slits into a parallel light flux. A boundary line extraction imaging exposure apparatus according to claim (1), comprising:
