Claims

[Scope of claims for utility model registration] 2 including at least one ballpoint pen fill
A front barrel in which the book file is stored and the writing characters of each refil selectively protrude from the opening at the tip; A cylinder is provided with a fitting hole formed inside, and the cam follower portion is connected to the rear end of each refil and moves back and forth within the cylinder, and the cam follower portion slidably engages with the cut groove to open the cylinder. From a rear shaft cylinder, which has an actuator protruding to the outside, an actuation spring that springs each actuator backward, and a cam surface that is rotatably attached to the cylinder and has a cam surface with which the cam follower of the actuator abuts inside. The actuator connected to the ballpoint pen fill has a large diameter part and a small diameter part formed through a tapered part, and when the ballpoint pen writing body is recessed into the front barrel, the large diameter part A two-core writing instrument, characterized in that the small diameter portion fits into the fitting hole of the cylinder, and when the actuator moves forward, the small diameter portion is located within the fitting hole.
