Abstract
A work positioner of a chip mounter comprising a positioner mechanism section for positioning a work such as a chip-shaped electronic part and a positioner driving section for driving the positioner mechanism section. The positioner mechanism section includes: guide plate; positioner blocks reciprocatively moving along at least one pair of guide grooves formed in a straight line and opposed to each other on the guide plate; and two pairs of positioner tips connected to the respective positioner blocks while clamping the guide plate in cooperation with the positioner blocks and adapted to open or close in operational association with the reciprocatory motions of the positioner blocks so as to clamp the chip-shaped work therebetween or to release it. The guide plate is clamped between the positioner blocks and the positioner tips, so that the positioner blocks and the positioner tips are caused to move along the guide grooves.
