PROBLEM TO BE SOLVED: To provide a locus pen which can beautifully draw a wavy line without particularly using an auxiliary tool for plotting.SOLUTION: A locus pen has an external frame, a driving member, a rotation member and a drawing member, the driving member is attached to the external frame and is rotated while contacting an object such as a paper, and the rotation member is attached to the external frame and comprises a pattern block. The rotation member has a pattern part of an uneven shape provided on an outer peripheral surface of the pattern block and is rotated by the driving member. The drawing member is attached to the external frame, comprises a push part which is reciprocated according to the uneven shape of the pattern part, and is so brought into contact with the pattern part as to correspond to the pattern part of the pattern block.SELECTED DRAWING: Figure 1 |
