Abstract (en)
[origin: JPH02303896A] PURPOSE: To effectively supply from a common recording material storage unit to both writing tips providing both the writing tips at the same end of a writing implement, and constituting both the tips to pass through one another. CONSTITUTION: The writing implement 1 comprises a writing implement body 2 fixedly disposing a pad 4 therein, a holding bush 5 inserted into an open end, and a writing tip 9 having a small diameter and inserted at its inside end into a lateral rib 5a. The tip 9 is slidably engagedly contained in a longitudinal hole 8 of the tip 7 having a large diameter over a most part of the length. Both the tips are concentrically passed from one another. The tip 7 is contained in a holding sleeve 6, and contained in an opened front end of the body 2. And, the tip 7 is projected or again retracted at an axially moving stroke 15 to the bush 5 depending upon the length and gradient of the slit 13 by relative rotation of the bush 5 to the sleeve 6. As a result, a recording material can be effectively supplied to both the tips.
