Claims

[Scope of utility model registration request]

When the lead case moves forward, the chuck releases the lead,
A front shaft houses a mechanism for feeding out the lead, a rear shaft is rotatably attached to the front shaft, a guide cylinder is fixed to the front shaft, and is biased backward by a spring to move the inside of the guide cylinder back and forth. The moving presser and the rear shaft rotate together.
The cam surface includes a cam follower that protrudes from the presser and a cam tube that comes into contact with it, and when the rear shaft is rotated in a predetermined direction and the cam tube rotates, the presser moves forward, contacts the core case, and moves it forward. A rotary-feeding mechanical pencil.
