Abstract

PROBLEM TO BE SOLVED: To enable easy identification of names of very small places and symbols included in a map when checking a position on the map by mounting a convex lens on an open/close lid. SOLUTION: A magnetic compass 1 for indicating directions of east, west, south and north is constituted of a pointer part 2 which has a pointer 4 rotatably mounted while equipped with a stopper 6a interlocking operation members and an open/close lid 3 which has a locking piece 3c and is equipped with a convex lens 3b by a mounting ring 3a. The locking piece 3c is formed on the open/close lid 3 to be retained on an open rim 2c of the pointer part 2. To close the open/close lid 3, the locking piece 3c is retained onto the open rim 2c pressing it. As the convex lens 3b is mounted on the open/close lid 3 by the mounting ring 3a, the magnetic compass 1 is placed on a map 8 and characters carried on the map 8 can be magnified to read checking the direction.
