<p><P>PROBLEM TO BE SOLVED: To realize contact breaking in a carrier having coaxial two wheels. <P>SOLUTION: Rotating shafts 305, 304, which are provided in an outer peripheral section 303 of a brake mechanism and supported by rotating shaft holders 312, 311 so as to be freely rotated around longitudinal axes of the rotating shafts, are coupled with a rotating shaft of motors 14, 15 through couplers 300, 301. The top of the rotating shaft 305 is inscribed on the inner circumferential side of a braking wheel 308 through a pulley 306, and the top of the rotating shaft 304 is circumscribed on the outer circumferential side of a braking wheel 309 through a pulley 307. Braking wheel rotating shaft holders 313, 314 are respectively provided in the centers of the braking wheels 308, 309, and a braking wheel rotating shaft holder holding bar 310 penetrates the centers of the braking wheel rotating shaft holders 313, 314 so as to be movable in the longitudinal direction. A moving lever 316, a moving lever rotating shaft 317, and a bearing 315 control the braking wheels 308, 309 to be contacted or separated. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
