By sliding the sliding body toward the tip of the shaft cylinder, the engaging protrusion formed on the rear end of one sliding body is locked to the locking portion, and the writing tip of one writing body is locked to the tip of the shaft cylinder. By maintaining the protrusion from the opening and sliding the other sliding body in the direction of the tip of the shaft tube, the engaging projection of one sliding body locked to the locking portion is engaged and disengaged. In a slide type multi-core writing instrument in which the writing tip of the body can be inserted from the tip opening, a clip is integrally formed on or attached to the other sliding body, and the rear end of the shaft tube from the tip end side to the outer wall of the shaft tube Toward the side, forming an inclined surface spaced from the axial center of the shaft tube, and the one writing The outer wall of the clip is pressed against the inclined surface by pressing the outer wall of the tip of the clip in the axial direction of the shaft while maintaining the writing tip of the writing from the opening of the shaft tube. It slides in contact with each other, releases the one engaging projection from the locking portion, and makes it possible to immerse the writing tip of the one writing body through the tip opening.

  In addition, the shaft tube is formed with a second inclined surface spaced from the shaft center of the shaft tube from the shaft tube tip side toward the rear end side, and the writing tip portion of the other writing body is used as the shaft tube tip. With the opening or protrusion maintained, the inner wall of the clip abuts against the second inclined surface and slides by pressing the outer wall of the tip of the clip in the axial direction of the barrel. With the contact portion between the clip and the second inclined surface as a fulcrum, the rear end portion of the other sliding body is separated from the shaft center, the other engagement protrusion is released from the locking portion, and the other The writing tip portion of the cursive body is immersible from the tip opening.

  In addition, a pressing portion that protrudes outward is formed on the outer wall of the distal end portion of the clip, and the top surface of the pressing portion extends from the distal end side to the rear end side of the axial tube. It is characterized by the fact that the inclined surface is separated from the axis.

  According to the configuration of the present invention, the outer wall of the tip of the clip is in the axial direction of the shaft cylinder in a state in which the writing tip of the other writing body is immersed in the tip opening of the outer wall of the shaft cylinder. In this way, an inclined surface that is spaced from the shaft center of the shaft tube is formed from the front end side of the shaft tube toward the rear end side, in which the clip contacts and slides. As a result, by sliding one sliding body in the direction of the tip of the shaft cylinder and maintaining the protrusion of one of the writing bodies, the outer wall of the tip of the clip is pressed in the axial direction of the shaft cylinder. The inner wall of the clip slides on the inclined surface so that the clip moves to the tip end side of the shaft tube, and the engaging protrusion of the one sliding body can be released from the locking portion.

  In addition, the outer wall of the tip of the clip is pressed in the axial direction of the shaft tube while the writing tip of the other writing body is kept protruding from the shaft tube tip opening to the rear shaft. By forming a second inclined surface separated from the axial center of the shaft tube from the front end side of the shaft tube toward the rear end side, the inner wall of the clip abuts and slides. The inner wall of the clip is brought into contact with the second inclined surface by pressing the outer wall of the tip of the clip in the axial direction of the shaft cylinder while the writing tip is kept protruding from the shaft tube tip opening. The sliding end of the one sliding body is separated from the axial center, and the other engaging projection is released from the locking portion with the contact portion between the clip and the inclined surface as a fulcrum. In addition, the writing tip of the other cursive body can be immersed from the tip opening. Because, without operating one of the slide, the locking of the concatenated clip at a position closer to the grip portion sliding body can be easily released.

  Further, by forming a pressing portion projecting outward on the outer wall of the tip portion of the clip, it becomes easier to press the outer wall of the tip portion of the clip, and the top surface of the pressing portion is By tilting away from the axial center of the shaft cylinder from the front end toward the rear end side, it is preferable because the clip slides smoothly on the inclined surface and the second inclined surface due to the pressing of the pressing portion.

  Since the present invention is configured as described above, a slide-type multi-core writing instrument that can easily release the protruding state of the writing tip can be provided with a simple structure.
