发明名称 VISIBLE BAR CODE INSPECTION METHOD AND DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a visible bar code inspection method and device that can inspect a visible bar code on a magnetic card for a pinhole shortly and precisely not through visual observation but with an inexpensive automated device. SOLUTION: The visible bar code inspection device, which inspects a visible bar code 4 processed on a magnetic card for a pinhole 5, comprises a carrier part with a carrier path for the magnetic card, and an inspection part for converting a reflection density of the visible bar code 4 read by an optical sensor 6 into a voltage and comparing it with a set voltage to determine whether there is any pinhole 5 or not. More sensors 6 than one are arranged at constant intervals along the longer side and shorter side of the visible bar code 4.
