<P>PROBLEM TO BE SOLVED: To prevent a worker from being burdened as much as possible when attaching a mounting head equipped with a suction nozzle. <P>SOLUTION: A guided portion 13 of each guided body 12 fixed to the back surface of a mounting head support 10 is inserted into a restriction guide groove 3A of each guide member 3 fixed to the top surface of a head support plate 2 from above, and then the each guided body 12 moves down while guided by the each guide member 3 and having its right-left direction and front-back direction restricted. As the each guided body 12 moves down, a lower end portion of a left guided body 12 eventually abuts against cam followers 6A and 6B to move the cam follower 6B away from the cam follower 6A against energizing force of a spring, so that the guided body 12 moves down while held between both the cam followers 6A and 6B. When the guided bodies further moves down, guided restriction surfaces 12C of both the guided bodies 12 slide down on guide restriction surfaces 6C and 7C of position restriction members 6 and 7, so that they stop moving down. <P>COPYRIGHT: (C)2010,JPO&INPIT |
