<p>It is necessary to supply electronic components to a precise location in a transfer station 26, the components being supplied in a plurality of magazines 22 e.g. for a component placement machine. Desirably the magazines may be readily exchanged without significant time being taken in setting up the magazine position accurately. Suitably the magazines are mounted on a turntable 24 each magazine having a location mark 362 positioned accurately relative to a transfer position 286. Drive means 264 moves the turntable 24 to present the transfer position 286 of the magazine 22 at the transfer station 26 and sensing means 358 senses the mark 362 when the supply means 18 is in a characterising mode. Information supplied by the sensing means 358 determines when the transfer position 286 is at a precise location of the transfer station 26. When the supply means 18 is in an operational mode, the transfer position 286 of the magazine is presented at the precise location of the transfer station 26, directly.</p> |
