Abstract
Pin head mounting members are rotatably mounted on a horizontal spindle above a table which horizontally supports a holding, plate holding chip type electronic components. The spindle is vertically movable by a vertical cylinder. Each pin head mounting member is shaped as a rectangular sleeve. A mounting surface is formed on each side portion of the pin head mounting member. A pin head each having a number of press pin is detachably mounted on each of the mounting surfaces A locking pin is provided on an upper end portion of the spindle for locking the pin head mounting members every 90.degree.. Thus, it is possible to efficiently replace press pins in response to a type change of chip type electronic components, as well as to quickly exchange a broken press pin.
