ALIGNMENT SYSTEM OF IMAGING DEVICE AND ITS METHOD

摘要

PROBLEM TO BE SOLVED: To realize a system and a method for positioning image beams related to an imaging device attached to a media handler. SOLUTION: The base 212 of a right triangle 200 is perpendicular to an image beam 142 and the top 200 is arranged to a position predetermined against an imaging device 300. An image beam 142 crosses with a hypotenuse point 250 on a hypotenuse 216 of the right triangle 200 and crosses with the base point 252 on the base 212. An alignment system measures the distance between the base point 252 and the hypotenuse point 250 and this distance corresponds to the position on the base 212 against the top 220. The alignment system makes the transverse axis position 512 of the image beam 142 against the top 220 as a reference and makes the ordinate axis position 514 of the image beam at the position the image beam 142 crosses the base 212 as a reference.
