Contact image sensing device

摘要

A contact image sensing device includes a housing, a light emitting unit, a red lens array, a sensing unit, and a protecting component. The housing includes a top surface, a bottom surface, an accommodating groove, and a slot. The bottom surface is opposite to the top surface. The accommodating groove is formed on the top surface and concave toward to bottom surface. The slot penetrates the top surface and the bottom surface. The light-emitting unit is arrange within the accommodating groove. The rod lens array is arranged within the slot. The sensing unit is arranged below the housing. The protecting component includes a main body, a recess, and a lighting slot communicating with the recess, a top end of the rod lens array is assembled with the recess. The main body of the protecting member forms at least one containing recess. A combining component for combining the rod lens array and the protecting member is disposed within the containing recess.
