<P>PROBLEM TO BE SOLVED: To solve the problem of the conventional optical scanning device in which: when an opening/closing lid is opened and the cleaning work of wiping off dirt on a reflective surface in a polygon mirror is carried out, it is difficult for service staff to clean the reflective surface in the polygon mirror because of the polygon mirror being positioned at the inside of a housing. <P>SOLUTION: The position relation between the installation position of a polygon mirror 207 and an opening A is set so that at least one of the reflective surfaces in the polygon mirror 207 is exposed to the outside of a housing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
