<p><P>PROBLEM TO BE SOLVED: To solve problems wherein the phase of projecting parts of a pair of couplings is different from each other every time in a conventional pair of couplings, a drive side coupling is idled before the pair of couplings are engaged and the drive can be transmitted, and the drive is not rapidly transmitted. <P>SOLUTION: When an object to be driven is pulled out of a body, a driven side coupling is constituted in a predetermined waiting phase, and the phase when the drive of the driving side coupling is completed has a predetermined relationship to the waiting phase of the driven side coupling. In the phase relationship, the driven side coupling is at the phase angle at which a tip of the projecting part is not collided with a tip of the driving side coupling. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
