PROBLEM TO BE SOLVED: To provide a slide extensible roller conveyor simplified in structure, manufacturable at low cost, easily extended/retracted, and increased in retraction length as the roller conveyor in an extended state is longer. SOLUTION: A roller conveyor 1<SB>-1</SB>comprises a guide rail 5, a movable guide 6, a slide guide, and a supporter. A guide frame 9 is installed on the left and right frames 3 of a roller conveyor 1<SB>-2</SB>. The movable guide 6 is connected to the front end of the frame of the roller conveyor 1<SB>-2</SB>through a link 10. When the link 10 is erected, the roller conveyor 1<SB>-2</SB>is raised to the upper side of the roller conveyor 1<SB>-2</SB>and to the height position to which the guide frame 9 is guided by the slide guide. In this state, the roller conveyor 1<SB>-2</SB>is slid to the upper side of the roller conveyor 1-<SB>1</SB>to shorten the overall length of the conveyor. COPYRIGHT: (C)2008,JPO&INPIT
