PURPOSE:To make positioning attainable so accurately with only mounting a machine body on an assembling block, by setting up a positioning device at the side of a bottom surface of the machine body, while performing horizontal positional regulation with a single positioning device in substance. CONSTITUTION:A positioning device 2 is fittably formed in a fitting member 10 being formed at the side of a assembling block, while positional regulation to the horizontal direction of a machine body 1 is made so as to be performed by the single positioning device 2. And, when the positioning device 2 is formed with a single member, the form is properly selected whereby the machine body 1 follows rotation of the assembling block 7, and thus is made so as to be rotatable without its racing. That is to say, on top of the fitting part 19, there are provided with a circular positional regulating part 21, a circular concave part 11 of the same form and a slit groove 12 extending at both sides of a center line A-A' passing the center of the circular concave part 11. The slit groove 12 is formed with the same width of a square convex part 22. |
