Abstract:
An image-forming machine comprising a housing and an image-forming unit allowed to freely move substantially horizontally between an acting position in said housing and a non-acting position drawn forward from said acting position,said image-forming unit including a frame that has a front wall member and a rear wall member arranged at a distance in a back-and-forth direction;wherein a pair of position-limiting means are arranged at a distance in a direction transverse to the back-and-forth direction on each of said front wall member and said rear wall member of said frame in said image-forming unit, andsaid housing includes a pair of front stationary position-limiting means and a pair of rear stationary position-limiting means, and when said image-forming unit is brought to said acting position, said pair of position-limiting means of said front wall member work in cooperation with said pair of front stationary position-limiting means and said pair of position-limiting means of said rear wall member work in cooperation with said pair of rear stationary position-limiting means, so that said image-forming unit is limited to said acting position, andwherein, amongst said pair of position-limiting means of said front wall member and said pair of front stationary position-limiting means, there is included a first pair of receiving holes that extend substantially horizontally, and a first pair of pins that extend substantially horizontally; and, amongst said pair of position-limiting means of said rear wall member and of said pair of rear stationary position-limiting means, there is included a second pair of pins that extend substantially horizontally and a second pair of receiving holes that extend substantially horizontally, andwherein annular shoulder surfaces are formed on said first pair of pins, and front ends of said first pair of receiving holes come into contact with said annular shoulder surfaces thereby to limit the position of said image-forming unit in the back-and-forth direction.
