できる。As described above, according to the present invention, the fitting is made only in this state by fitting into the fitting hole of the hook-shaped first engaging hole provided in one member. Since the second engagement piece and the second engagement hole are engaged with each other, even if there is some error in molding between the leg and the engagement hole, by fitting these, Not only can the two members be fixedly connected in both the surface direction and the plate thickness direction, but also when these members are formed in the stage of engagement between the first engagement piece and the second engagement hole. Since the second engagement piece can be engaged with the second engagement hole by utilizing the large elastic deformation,
The two members can be automatically and firmly connected and fixed.

とができる。Further, by applying this coupling mechanism to the paper guide member of the printer, the first engagement piece can be integrally formed within the range of the shape and size required for the paper guide member. The paper guide can be securely connected only by simply fitting the paper guide into the printer main body, and the production cost of this type of printer can be greatly reduced.
