<p>PURPOSE:To easily adjust the position of a guide post by combining a guide post unit with a drum base through a slanting component of the guide post in the center direction of the drum base, and constituting the guide of a chucking part slantingly to a slanting component in a tangential direction. CONSTITUTION:When guide posts P and P' slant at an angle theta from the X axis and at an angle psi from the Z axis, the component angle in the X-axial direction is alpha and the component angle in the Y-axial direction is beta. Then, the guide post 14 is constituted slanting by the angle alpha to the center line (m) of the drum base 11, so when the unit 12 is checked, it slants in the tangential direction because of a guide groove slanted by the angle beta, so the guide post 14 also slants by the angle beta. Namely, the inclination alpha in the center direction to the drum base 11 and the inclination beta in the tangential direction are put together, so the guide post 14 is slanted and positioned by the specific tilt angle psiin a direction having the angle theta to the center line (m). This positioning mechanism facilitates the work of the chucking member and the position adjustment of the guide post.</p> |
