摘要 |
The invention provides a device for capturing images three-dimensionally which comprises a rail <HIL><PDAT>2 </BOLD><PDAT>extending around a three-dimensional object images of which are to be captured, an image pickup head <HIL><PDAT>3 </BOLD><PDAT>movable along the rail <HIL><PDAT>2</BOLD><PDAT>, a signal cable <HIL><PDAT>8 </BOLD><PDAT>interconnecting a head terminal <HIL><PDAT>81 </BOLD><PDAT>on the head <HIL><PDAT>3 </BOLD><PDAT>and a signal relay terminal <HIL><PDAT>82 </BOLD><PDAT>on the rail <HIL><PDAT>2</BOLD><PDAT>, an auxiliary cable <HIL><PDAT>83 </BOLD><PDAT>interconnecting a head-side connecting point <HIL><PDAT>85 </BOLD><PDAT>on the head <HIL><PDAT>3 </BOLD><PDAT>and a rail-side connecting point <HIL><PDAT>84 </BOLD><PDAT>on the rail <HIL><PDAT>2</BOLD><PDAT>, and a connecting member <HIL><PDAT>9 </BOLD><PDAT>having the signal cable <HIL><PDAT>8 </BOLD><PDAT>and the auxiliary cable <HIL><PDAT>83 </BOLD><PDAT>slidably reeved therearound for turning back the cables in directions opposite to each other. The signal cable <HIL><PDAT>8 </BOLD><PDAT>extends from the head terminal 81 in one direction, is turned back on the connecting member <HIL><PDAT>9 </BOLD><PDAT>and extends to the signal relay terminal <HIL><PDAT>82</BOLD><PDAT>, while the auxiliary cable <HIL><PDAT>83 </BOLD><PDAT>extends from the head-side connecting point <HIL><PDAT>85 </BOLD><PDAT>in the opposite direction, is turned back on the connecting member <HIL><PDAT>9 </BOLD><PDAT>and extends to the rail-side connecting point <HIL><PDAT>84. </BOLD></PTEXT> |
