<p><P>PROBLEM TO BE SOLVED: To provide a ball marker comprising a battery and a light-emitting element, which eliminates the need for switch operation, miniaturizes and prevents mud or water from entering. <P>SOLUTION: The ball marker comprises an attaching part which butts against a predetermined position of a ball marker holder comprising a magnet when it is attached to the holder, the light-emitting element emitting fluorescence, the battery for supplying power to the light-emitting element and a control part which stops power supply to the light-emitting element by magnetic force so as to turn off the light-emitting element. Accordingly, it is possible to obtain the ball marker which allows the easy identification and elimination of operation for turning on or off light and which has durability against mud, water or the like, excellent portability and usability. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
