<P>PROBLEM TO BE SOLVED: To miniaturize a drive coupling mechanism by reducing the required movable amount of a coupling in engaging a drive coupling pair. <P>SOLUTION: In the coupling pair for transmitting drive, at least one coupling element is movable in an axial direction and energized toward the other coupling element forming the pair, and a guide part is provided at an engaging part between the coupling and a shaft so that the coupling element is rotated in the circumferential direction of the shaft when the energized coupling element is pushed into an opposite direction to the energized direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
