<p>PURPOSE:To make a boat supportable in its vertically located condition so that a base plate can be transferred in a small space with high accuracy by providing a support mechanism for locating and supporting at least one end of the boat. CONSTITUTION:A boat mounting bed 5 is moved in its rotation by a rotational mechanism to set a boat 4 to a transfer position where an abutting body 20 provided on a support mechanism 17 is lowered by the drive of an air cylinder 21 to be fitted to an recess 22 on the upper end of the boat 4. Then, the recess 22 is formed with a tapered groove and the abutting body 20 has a tapered projection, so that the abutting body 20 and recess 22 abut and fit to each other. Thus, the boat 4 can be located in a predetermined position and supported so that it is prevented from being brought down.</p> |
