The operation element 7 corresponding to each writing element 6 is connected to the rear end of each writing element 6. A plurality of aperture holes 41 extending in the longitudinal direction are provided radially penetrating a sidewall of the shaft cylinder 2. Each operation element 7 is projected radially outward from each aperture hole 41. The rear end of the shaft cylinder 2 has an openable/closable opening 42 for opening the aperture holes 41 backward. The writing element 6 and the operation element 7 are removable from the inside of the shaft cylinder 2 and insertable into the shaft cylinder 2 through the opening 42. COPYRIGHT: (C)2011,JPO&INPIT
