A leg unit includes a positioning pin projecting from an upper surface of a seat plate thereof, and an image forming unit includes a positioning hole formed on a mounting surface thereof. Delimiting portions project downward from the lower ends of left and right lateral faces of the image forming unit. The delimiting portions oppose respective outer lateral faces of the seat plate so as to restrict a relative movement of the image forming unit. A projecting portion is provided on the outer lateral face of the seat plate. The positioning pin can be fitted in the positioning hole by engaging the projecting portion with a recess of the delimiting portion. The delimiting portion includes a stopper formed on the respective sides of the recess in the longitudinal direction thereof, for restricting the sliding motion of the projecting portion along the lower end face of the delimiting portion.
