<P>PROBLEM TO BE SOLVED: To enable a pen tip to change inflection and a width of handwriting by enabling pen base bodies to recede by a writing pressure upon writing at the pen tip in which a plurality of rigid pen base bodies whose tips do not deflect in an axial diameter direction by the writing pressure are arranged in an axial body in a circumferential manner such that writing can be performed from any direction. <P>SOLUTION: A pen base body holding member 4 is configured with a front protruding section 4a having a small diameter, a body section 4b which has a plurality of holding grooves 6 in a circumferential manner which move away from an axial center as the holding grooves move backward, a small axial section 4c having a small diameter, and a back end guard section 4d, and an ink flowing passage 8 which communicates back and forth is provided, and a slit 9 is provided at the front protruding section 4a. An inserting and attaching section 2c which freely engages with the front holding grooves 6 is provided, the plurality of rigid pen base bodies 2 whose tips 2a have cut grooves 3 are inserted and attached inside the axial body 5 so as to be able to move back and forth by inserting the inserting and attaching section 2c in the holding grooves 6 of the body section 4b and extending a coil spring 15 between the pen base bodies 2 and the pen base body holding member 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
