Claims

[Claims for Utility Model Registration] (1) A cam cylinder that has a locking part formed at the top of the cam surface that allows a cursive to obtain a writing state, and the cam surface of the cam cylinder slides to engage and disengage from the top. has a protrusion that
By inserting a sliding body that moves only in the axial direction and rotating the sheath body that operates integrally with the cam cylinder, the writing body that presses against the sliding body emerges and retracts from the rear end opening of the shaft cylinder. In the mechanism, the tip of the hollow inner cylinder 3 fixed to the shaft cylinder 4 is formed into an inward flange 3b, and the cam cylinder 1 is inserted into the hollow inner cylinder 3.
A ring member 5 is fitted to the outer surface of the inward flange portion 3b of the hollow inner cylinder 3 via a washer member 6, and the small diameter extension portion 1b of the cam cylinder is connected to the washer member 6 and the sheath body 9. A device for displaying and retracting a writing body, characterized in that a coil spring S' is installed between the stepped portion 7 formed in the cursive body. (2) The small-diameter extension 1d of the cam cylinder 1 is removably connected to the intervening member 8 having a larger diameter than the small-diameter extension 1d, and the long threaded part 8a is formed at the end of the intervening member 8. , a long threaded part 9 is also provided at the end of the sheath body 9.
Claim 1 characterized in that the threaded portions 8a, 9a', the cam cylinder 1, and the sheath body 9 are engaged in such a manner that the threading positions in the longitudinal direction of the cam cylinder 1 and the sheath body 9 can be specified at desired positions. The cursive writing device described in .
