PROBLEM TO BE SOLVED: To enhance learning ability in recognition of relation between time and clocking by making handling convenience. SOLUTION: For the numeric line tape body 1, five nicks each of which represents one minute are formed, and the nicks on twelve numeric line tapes correspond to sixty minutes of a timepiece. A projection 12 formed in an engaging structure is formed on one end of the body, and a recessed part 13 formed in an engaging structure is formed on the other end. A recessed groove 15 is arranged on the rear face of the body, and a flexible magnet 16 is stuck on the recessed groove. Thus the numeric line tape can be fitted to any plate body that can be attracted by the magnetism. COPYRIGHT: (C)2006,JPO&NCIPI
