<P>PROBLEM TO BE SOLVED: To suppress an impact made when a projection part, for positioning an openable/closable door is inserted into a projection-part insertion hole when the openable/closable door is closed in an image forming apparatus. <P>SOLUTION: Since a positioning pin 91A is arranged at a position at a shorter distance than a distance of a perpendicular line down to a center of rotation of a first supporting plate 70 from a positioning pin 91B, after positioning of the right side of the first supporting plate 70 is finished, positioning of the left side thereof is performed. By shifting timing when the positioning pin 91 is inserted into a positioning hole 93, the impact made when the positioning pin 91 is inserted into the positioning hole 93 is suppressed. Furthermore, since the positioning hole 93A is formed in ellipse shape long in a lateral direction, the positioning pin 91A is easily inserted, thereby moderating the impact made when the positioning pin 91A is inserted, and also positioning to lift up the first supporting plate 70 to an upper side (Z(+) side) is performed. By inserting the positioning pin 91B into the positioning hole 93B, final positioning of the first supporting plate 70 relative to a front side frame 43 is performed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
