The running guide member () has a flat portion forming a guide face portion () for facing to the optical tape () is operative to cause the optical tape () to run along the flat portion. Thereby, an area on the guide face portion () of the running guide member () where an incident position on the optical tape () of a light beam is fixed invariably can be stably maintained to be relatively wide.
