Abstract
A pick and place apparatus includes a 1st to an nth device holding element arranged in a lengthwise direction, every one of the 1st to the nth device holding element being connected to its neighboring one(s) of the 1st to the nth 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 1st device holding element and a second coupling part at a lower part thereof for being coupled to the nth 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 1st and the nth device holding element such that the 1st device holding element moves in a direction opposite to the nth device holding element.
