PROBLEM TO BE SOLVED: To prevent the inability of use when the ink amount still remains inside by fitting a pen point holder outer diameter site on an open section inner diameter of a main body cylinder rear section and connected with thereon and providing a rear cover releasably on the rear end of the main body cylinder of a pen main body cylinder connecting tail end. SOLUTION: A main body cylinder 6-1, from which a cap 8 of the top order portion of a connecting constitution is removed, is removed from a pen main cylinder 6-2 of the following portion, and a pen point holder site is inserted and fitted into the rear end from which the rear end 7 of a pen main body cylinder 6-3 on the tail end section is removed, and a cap 7 is fitted on the rear end of the pen main body cylinder 6-1. The pen main body cylinder 6-1 is located on the connecting tail end by the arrangement, and the connecting order is changed to (6-2)+(6-3)+(6-1), and the new order is applied repeatedly during the use. The ink sucking-up distance is shorter because of the shorter sizes of respective pen main body cylinders while the required length of a writing implement is retained in the above constitution to prevent the lowering of the sucking-up function and effectively consume the filled ink amount. |
