[First Embodiment]
1 to 4, the writing instrument body 3 is cylindrical, and the pen tip 4 of the ballpoint pen core 18 protrudes from the hole 5 at the tip of one end, and the outer periphery 24 of the intermediate part extends in the longitudinal direction of the writing instrument body 3. A groove portion 14 is formed so as to extend along the shaft, and a shaft portion 22 centering on an axis 11 that is substantially perpendicular to the longitudinal direction of the writing instrument body 3 passes through both support portions 13 at the other end portion. It is integrally molded, and a core 18 is accommodated in the interior 19. Here, the detailed structure for inserting the core 18 into the interior 19 is omitted in FIGS. 1 to 4, but in reality, one end of the writing instrument body 3 is separated and screwed after the core 18 is stored. Such a structure is conceivable. Further, the pen tip 4 can be stored as a knock type, or the ink color can be selected as a multi-core type.

  Further, the arm 1 has a shape in which a cylinder is vertically divided, and has a flat sandwiching portion 6 at one end portion and a V-shaped groove shape at a middle portion in a direction substantially perpendicular to the longitudinal direction of the arm 1. 20 and a finger hook 8 are integrally provided on the outer periphery of the other end. The arm 2 is also shaped like a vertically split cylinder, with a flat sandwiching portion 7 at one end and a V-shaped groove at the middle portion in a direction substantially perpendicular to the longitudinal direction of the arm 2. 21 and a finger hook 9 are integrally provided on the outer periphery of the other end.

  Further, when assembling, the shaft portion 22 is fitted into the groove shape 20, the shaft portion 22 is subsequently fitted into the groove shape 21, and then the one end portion 16 of the urging member 15, which is a C-shaped spring, is sandwiched between the arms 1. The other end 17 is brought into contact with the intermediate outer periphery of the sandwiching portion 7 of the arm 2 and the groove shape 21 on the outer periphery in the middle of the groove shape 20. The assembled clip 10 has a cylindrical shape, and is urged by the urging member 15 in the direction in which the arms 1 and 2 approach each other, thereby generating an urging force in the direction in which the clamping portions 6 and 7 are closed, and the shaft portion 22. Since the urging force is also generated in the direction sandwiching the groove portions 20 and 21, when the clip 10 swings about the shaft portion 22, the shaft portion 22 and the groove shape 20 and between the shaft portion 22 and the groove shape are formed. Since an appropriate frictional force is generated during 21, the clip 10 can be easily clamped at an appropriate swing angle.

  Further, in the first state as shown in FIG. 3, the outer periphery of the arm 1 is fitted in the groove shape 14 so that the arm 1 can no longer swing clockwise on the paper surface. 4 can be swung as shown in FIG. 4 counterclockwise about the axis 12 that is concentric with the axis 11. In the second state as shown in FIG. 2, the other end of the arm 2 hits the contact shape 23 of the writing instrument body 3, and the arm 2 is restricted so that it cannot swing further counterclockwise. The arm 1 can swing clockwise about the axis 12 by pinching the hooks 8 and 9 with fingers.

Further, in the state as shown in FIG. 4, it is easy to store in the breast pocket, and in the state as shown in FIG. 1, the holding parts 6 and 7 are opened and the edges of the heel are sandwiched, and then the writing instrument body 3 and the clip 10 are attached. It can also be used in such a way that the writing instrument body 3 is brought close to the heel by relative swinging.
Further, in the state as shown in FIG. 1, it is possible to perform reliable writing by picking one end of the writing instrument main body 3 with a finger and placing one end of the arm 1 near the root of the thumb and forefinger.

[Second Embodiment]
Since the second embodiment is a small change of the writing instrument with a clip of the first embodiment, only the changes will be described.
5 and 6, the shaft portion 22 centering on the axis 11 is a shaft pin that is press-fitted into and supported by the through holes provided in both support portions 13.

  Further, a through hole 25 is formed in the convex shape of the middle part of the arm 1 in a direction substantially perpendicular to the longitudinal direction of the arm 1. In addition, through holes 26 are formed in two convex shapes in the middle part of the arm 2 respectively disposed at both ends of the through hole 25 in a direction substantially perpendicular to the longitudinal direction of the arm 2.

  Further, at the time of assembly, the one end 16 and the other end 17 of the urging member 15 which is a cylindrical coil-shaped compression spring are brought into contact with the inner sides of the finger hooks 8 and 9, respectively. The through holes 25 and 26 are arranged, and the shaft pins constituting the shaft portion 22 are inserted so as to pass through the through holes 25 and 26 and fixed to the both support portions 13. Further, the urging member 15 is urged in the direction in which the finger hooks 8 and 9 are separated to generate the urging force in the direction in which the clamping parts 6 and 7 are closed. Since the urging force in the sandwiching direction is also generated, when the clip 10 swings around the shaft portion 22, it is between the inner periphery of the shaft portion 22 and the through hole 25, and the inner periphery of the shaft portion 22 and the through hole 26. Since an appropriate frictional force is generated during this period, the clip 10 can be easily clamped at an appropriate swing angle.

[Third Embodiment]
Since the third embodiment is a small change of the writing instrument with a clip of the first embodiment, only the changes will be described.
7 and 8, a shaft portion 22 centering on the axis 11 is a shaft pin that is press-fitted and supported in through holes provided in both support portions 13.

Further, the intermediate portion of the arm 1 and the intermediate portion of the arm 2 are integrally molded so as to be connected by the connecting portion 27.

  Further, when assembling, the through hole 25 is disposed between the both support portions 13, and the shaft pin constituting the shaft portion 22 is inserted and fixed to the both support portions 13 so as to penetrate the through hole 25. Further, an urging force in a direction in which the clamping portions 6 and 7 are closed is generated by urging by the elasticity of the materials of the integrally formed arms 1 and 2 and the connecting portion 27. Further, the arms 1 and 2 are disposed in the vicinity of the connecting portion 27 and are relatively swingable about the axis 12 that is substantially parallel to the axis 11.

  Further, in the second state as shown in FIG. 8, the other end of the arm 1 comes into contact with the contact shape 23 of the writing instrument body 3, and the arm 1 is restricted so that it cannot swing further counterclockwise on the paper surface.
