PURPOSE:To simplify assembling work by dispensing with a screwing process, by a method wherein protruding pieces are provided to the reference surfaces on both sides receiving one surface of a frame plate and a redge part is provided to one of said pieces, and wall surfaces coinciding with the width of the frame plate and the pawls having inclination brought into contact with the reference surfaces under pressure when the frame plate is brought into contact with the reference surfaces are integrally formed to both sides of the reference surfaces. CONSTITUTION:When a frame plate 1 is moved in such a state that a window 11 is engaged with the protruding pieces 21 of side frames 2, both sides of the frame plate 1 are guided by inclined surfaces 24a and cross wall surfaces 22, 22' at a right angle to move toward reference surfaces 23, 23'. When the frame plate 1 is brought into contact with the reference surface 23, the frame plate 1 is brought into contact with the reference surfaces 23, 23' under pressure in such a state that the back surface thereof is engaged with pawls 24, 24' and elastically pressed to the wall surfaces 22, 22' in the width direction thereof to be fixed at a definite position. In the fixed state, clip members K are engaged with the protruding pieces 21 and the end parts of the frame plate 1 and the end parts K' thereof are brought into contact with the guide shaft of a carriage to certainly fix a machine frame 2 and the frame plate 1, and the carriage and the frame are electrically connected to enhance noise resistance. |
