ABSTRACT:
An electronic part mounting apparatus wherein an original orientation position of a nozzle can be restored accurately at a high speed with a simplified structure includes an index table supported for rotation around a first axis, and a nozzle mechanism carried on the index table and having a nozzle. The nozzle mechanism includes an original orientation returning gear mounted for rotation around a second axis on the index table for returning the nozzle to a predetermined original orientation position. The apparatus further includes an original orientation restoring mechanism including an original orientation restoring gear mounted for rocking motion into meshing engagement with the original orientation returning gear to rotate the original orientation returning gear to position the nozzle at the predetermined original orientation position, and a mechanism for rocking the original orientation restoring gear toward the original orientation returning gear to engage, during such rocking motion, the original orientation restoring gear with the original orientation returning gear when the rotational speed of the original orientation restoring gear reaches a predetermined value.
