Abstract: To provide a rod-like light guide and a line lighting device including the rod-like light guide, both of which are easy to include in an image reading device, a contact-type image sensor and an image reading device. For instance, a protruding portion having a flat or curved surface is formed by grinding an end face of a rod-like light guide in a longitudinal direction while leaving at least 80% of the surface area of the end face, and a reflective surface is formed by bonding a heat transfer film to the protruding portion. Thus, even if a portion of the protrusion portion melts when performing thermal processing on the heat transfer film, the portion will not jut out beyond a cross-sectional area of the rod-like light guide, and the rod-like light guide can be easily contained in a case.

Abstract: A coating and developing system has a first processing block, a second processing block, and a transfer block interposed between the first and the second processing block. A first direct carrying means carries substrates from a carrier block to the transfer block. The transfer block distributes the substrates to respective film forming unit blocks of the first and the second processing block. Substrates on which films have been formed by the first and the second processing block are collected temporarily in the transfer block. A second direct carrying means carries the substrate collected in the transfer block from the transfer block to an interface block. Use of the first and the second processing block can improve the throughput of the coating and developing system. Since a carrying route from the carrier block to the first processing block, and a carrying route from the carrier block to the second processing block are the same, a carrying program is easy to create.
