<p>A management board of articles which magnetically stores data related various articles, a method of producing the same, and a management system of articles in which the management board (A) of articles is mounted on a high-pressure gas cylinder (20) that is installed outdoors, the data are read by a magnetic sensor (15), digitally displayed on a display unit (16), and are collected and managed by a host computer (18). On a magnetically non-permeable substrate (1) are studded or fitted magnetically permeable article management pins (9) and on a magnetically permeable substrate (21) are studded or fitted article management holes (29) using a studding device or a perforator. On the periphery (4, 24) of the magnetically non-permeable substrate (1) or of the magnetically permeable substrate (21) are formed reference holes (5, 25) for reading the stud or perforation of the article management pins (9) or the article management holes (29) to realize management boards (A, B) of articles which are stuck to the high-pressure gas cylinder (20). Read reference pins (15F) of magnetic sensors (15, 35) are fitted to the reference holes (5, 25) in the periphery (4, 24). The article management pins (9) or the article management holes (29) are read by the reading head (15), converted into digital values through a microcomputer (17), displayed on the display unit (16), and are collected and managed by a host computer (18).</p> |
