<p>A pick and place apparatus includes a 1<SUP>st</SUP> to an n<SUP>th</SUP> device holding element arranged in a lengthwise direction, every one of the 1<SUP>st</SUP> to the n<SUP>th</SUP> device holding element being connected to its neighboring one(s) of the 1<SUP>st</SUP> to the n<SUP>th</SUP> device holding element by means of at least one pitch setting ring; a belt having a first coupling part at an upper part thereof for being coupled to the 1<SUP>st</SUP> device holding element and a second coupling part at a lower part thereof for being coupled to the n<SUP>th</SUP> device holding element; and a driven pulley and a differential pulley. The driven and the differential pulley are rotated by being engaged with the belt to move the 1<SUP>st</SUP> and the n<SUP>th</SUP> device holding element such that the 1<SUP>st</SUP> device holding element moves in a direction opposite to the n<SUP>th</SUP> device holding element.</p>
