Abstract
A pair of carriage rails are provided in parallel to each other in a casing. A carriage moves along the carriage rails. Both ends in a longitudinal direction of each of the carriage rails are fixed to the casing. A cross member functioning as a lens base is suspended between the carriage rails. Both ends of the cross member are fixed to a section between both the ends of the carriage rails. Intermediate sections in the longitudinal direction of the carriage rails are coupled to sidewalls of the casing via a coupling section.
Claims20
An image scanning unit comprising:
- a casing having a pair of sidewalls;
- a pair of carriage rails provided in parallel to each other along the sidewalls;
