されている。Recently, the number of colors of ball-point pen ink has increased, and multiple ball-point pen cores with different ink colors are concentrically arranged inside the barrel to selectively project the pen body of the ball-point pen from the tip opening of the barrel. The multi-core writing instrument of the ball-point pen has been put into practical use. In such a multi-core writing instrument, color-coded actuators are connected to the tail end of a ball-point pen core, which is a writing body, and the pressing portion of the actuator is provided with a plurality of window holes formed in the outer peripheral surface on the tail end side of the barrel. From each of which protrudes in the radial direction. Then, when the pressing portion of the operator of the color to be written, which is exposed from the window hole of the barrel, is moved forward in the axial direction by the fingertip, the ball-point pen core advances and the pen body, which is the writing portion, projects from the tip opening of the barrel. At this time, since the pressing portion of the actuator is also pressed radially by the fingertip, the ball-point pen core is slightly displaced toward the axial center of the shaft cylinder, and the pressing portion of the actuator is almost inserted into the shaft cylinder. It engages with the locking part of and receives writing pressure. Also,
On the back surface of the operator, two protrusions for driving backward and for driving backward are formed up and down, and in the process of forward movement of the operator, the lower backward driving one is in the forward position and the other ball-point pen core is in the forward position. The core hits the backward drive projection of the operator and pushes the core toward the peripheral portion from the axial center of the barrel. Accordingly, the engagement of the other ball-pon core operator in the forward position with the locking portion of the barrel is released, and the ball-pond core retracts. The writing body is not limited to a ball-point pen core, and a multi-core writing implement for a mechanical pencil and a ball-point pen is being considered by accommodating a plurality of ball-point pen cores and one or a plurality of mechanical pencil filling materials.

端開口21から突出して第１図に示す状態になる。Then, when writing with a ballpoint pen, the pressing portion 41 of the actuator 4 for the ballpoint pen of a predetermined color is pressed with the fingertips and moved forward in the axial direction. At this time, since the pressing portion 41 is also pressed in the radial direction by the fingertip, the ball-point pen core 7 is slightly displaced toward the center of the shaft cylinder 10, and the pressing portion 41 is positioned inside the rear shaft 1 as shown in FIG. The retracted drive projection 42 is located at the center of the rear shaft 1 when it comes in, and the top surface of the operator 4 engages with the locking portion 13 to receive the writing pressure. At the same time, the pen body 71 projects from the front end opening 21 of the front shaft 2 to be in the state shown in FIG.

なる。Next, when writing with a mechanical pencil, the upper end of the clip 6 is pressed with a fingertip to advance in the axial direction. Also in this case, the mechanical pencil tool 8 is slightly deviated toward the center of the barrel 10, and the retracting drive projection 52 of the actuator 5 is located at the center of the rear shaft 1. It abuts the driving projection 42 and pushes it outward. Therefore, the engagement between the top surface of the operator 4 and the locking portion 13 is released, the ball-point pen core 7 is retracted, the pen body 71 is retracted from the tip opening 21 of the front shaft 2, and the tip 81 is replaced and the tip is replaced. It projects from the opening 21. At this time, the top surface of the actuator 5 is engaged with the locking portion 13 to receive the writing pressure, but as shown in FIG. 2, the outer step portion 81a of the front opening 81 has the inner step portion 21a of the tip opening 21. The front end 81 becomes incapable of advancing any more. When the clip 6 is further advanced from this state, the pencil lead, which is the writing section, is fed out, and the writing becomes possible.
