CONTAINER CARRIER

PROBLEM TO BE SOLVED: To move positioning members 12 in the radial direction and to lock them so as not to move furthermore so that a container carrier 2 supporting and conveying a container 4 by four positioning members 12 can be used both for it and the container 4 with a different size. SOLUTION: Four positioning members 12 are engaged in four guide channels 8a in the radial direction formed on a supporting member 8 and are movable in the radial direction. As projections 12a provided on the undersurface of respective positioning members are engaged in four spiral cam channels 6a formed in a cam member 6 arranged in the lower surface of the supporting member, when the supporting member and the cam member are relatively rotated, the positioning members are moved in the radial direction. Pin storing holes 8b deeper than magnet pins 16 are formed on the undersurface on the supporting member, and a plurality of pin inserting holes 6b shallower than the pins 16 are formed on the upper surface of the cam member. When the pins 16 are lifted up by the magnets 30b, the supporting member and the cam member can be relatively rotated. COPYRIGHT: (C)2009,JPO&INPIT
