PURPOSE: To correct the deformation of an outer cover rotatably supported by a main body, to reduce the number of parts, to simplify the assembly and to increase a space for a description for explaining the operation of the main body, etc. CONSTITUTION: The box-like outer cover 50 is provided with positioning pins 50k and 50m which are separated from each other in the longitudinal direction of the cover. The holes 60a and 60b of an inner cover 60 are fitted onto the positioning pins, and a male screw 70 is firmly screwed into a female screw 50f to be fixed there. Thus, the rigidity of the outer cover 50 increases. The inner cover 60 may be formed so that it is integrated with a function member. |
