MICRO PRISM ARRAY FOR EXPOSURE DEVICE HAVING A FUNCTION OF LIGHTBEAM DIFFUSING SHUTTING

摘要

PURPOSE: A micro prism array for an exposure device according to the present invention is provided to improve the exposure efficiency thereof by condensing a transmitted light. CONSTITUTION: A light incidence unit(210a) is widely formed and a light emitting unit is narrowly formed(210b). A diffused light shutting unit(211) condenses a transmitted light with secluding 'the diffused light giving influence to a neighboring pixel'.
