Title: Commodity information reader
Inventor: SUGIYAMA TETSUO
IPC: G06K7/10
Filed: 1994-03-10
Abstract: PURPOSE:To speedily and accurately read commodity information out and to widen the adaptability and facilitate the handling by switching the output direction of a scanning beam so that the scanning beam is outputted through the scanning window corresponding to a detected commodity transfer direction. CONSTITUTION:When a commodity is almost conveyed above the upper scanning window 15WU of a read unit 15A, a commodity conveyance direction detection means 30A previously detects the commodity being conveyed above in connection with the commodity or the arm holding the commodity. Then an output direction switching control means performs switching drive control over a scanning beam output direction switching means to perform automatic switching so that the scanning beam from a light emission unit 151 is emitted out through the upper scanning window 15WU. A customer can read commodity information on the reverse surface on the commodity even when the article is passed above the upper scanning window 15WU as it is. When the commodity is conveyed below the lower scanning window 15WD, similar automatic switching is performed, so the scanning beam is emitted out of the lower scanning window and an accurate read can be made in either case.
