Patent ID: 7251021

Claim:
A substrate transfer apparatus comprising pluralities of pairs of substrate support mechanisms, the substrate support mechanism comprising: a first roller provided on a first rotary shaft; and a second roller provided on a second rotary shaft, wherein the substrate support mechanism transfers a substrate in a transfer direction while supporting the substrate between the first and second rollers in a thickness direction of the substrate, wherein the pair of the substrate support mechanisms are disposed so as to oppose to each other in a width direction of the substrate, the pairs of the substrate support mechanisms are arranged along with the transfer direction, and a substrate position regulating member comprising a third roller that regulates a position of the substrate by contacting with a side surface which is parallel to the transfer direction is provided on one of the first and second rotary shafts, wherein the third roller integrally rotates with either the first or second rotary shaft to thereby reduce a load applied to the side surface of the substrate.
