Abstract

PURPOSE:To discriminate a foreign mark such as dirt, etc., and to read a mark with high accuracy, by adding fluorescent light emission substatnce powder or bright reflection substance powder into a painting material and putting a character or a mark, so that it can be read out under the condition that is has been irradiated by a light source body conforming to the added substance, when reading. CONSTITUTION:Data is sent to a marking mechanism 3 through a marking control mechanism 2 from a computer 1, and marking of a discriminating No., etc. is executed to an object article such as a pipe, etc. When marking, in this marking painting material, fluorescent light emission substance powder or bright substance powder such as glass powder, etc. is added. After that, an article 4 is placed on a turning mechanism 5 of a read station, is rotated, a discriminating symbol 6 is irradiated by a light source body 7, is read by read mechanisms 8, 9, and its read data is inputted to the computer 1. As this light source body 7, ultraviolet rays or incandescent lamp rays conforming to the substance powder added into the painting material are used, by which a foreign mark caused by dirt, etc. is discriminated easily, and a mark is read with high accuracy.
