[0006]

[Means for Solving the Problems]

 The present invention was devised through repeated experiments and examinations to solve the above-mentioned problems in the conventional technology. The present invention also proposes a writing implement that has a display section on the upper end of the shaft that simultaneously changes the rotation and that can display a character shape and other various contents, and that adds a member that performs a complex and large operation. Specifically, it is as shown below.

(1) A wire is spirally wound around the outer periphery of a shaft having a display portion at the upper end and having a length equal to or more than half the length of the writing cylinder, and the shaft is fixed to the upper end of the writing cylinder of the writing instrument. It is moved up and down by operating an operating lever that is inserted through the opening and protrudes out of the writing cylinder, and the lower end of the shaft is resiliently moved upward by the elasticity of the spring disposed in the writing cylinder. The edge groove of the opening of the cover material at the upper end of the writing cylinder acts as a guide portion for the wire wound in a spiral shape, so that the shaft itself moves with the vertical movement of the shaft. A writing instrument having a rotating and vertically moving display unit, characterized in that the display unit rotates and the display unit also rotates.

[0008] (2) The convex portion formed in a spiral shape on the outer periphery of the shaft is formed by winding a wire, and rotates and moves up and down according to the above (1). Writing implement with display.

(3) The rotation according to the above item (1) or (2), wherein when the lower end portion of the shaft reaches the lower end in the writing cylinder, the writing implement is moved into and out of the operation section. Writing instrument with a display unit that moves and moves up and down.

[0010]

[Embodiment of the invention]

 With respect to the above-described product of the present invention, an example in which a convex portion is formed using a wire will be described as a typical embodiment with reference to the accompanying drawings. That is, FIG. 1 relates to the writing instrument 1 of the present invention, in which the shaft 4 is projected to the outside of the writing cylinder 2 by the elastic action of the spring 3 in the writing cylinder 2, and the operation of the operating lever 5 by a user or the like is performed. This state is maintained unless otherwise performed.

As shown in the figure, a wire 6 is fixed to the shaft 4 by forming a convex portion around the outer periphery of the wire 6 in a spiral manner. The wire 6 should have a considerable rigidity such as a wire or a piano wire. The length of the shaft 4 is at least half the length of the writing cylinder 2, and such a relatively long member moves up and down with respect to the writing cylinder 2. As a result, it is possible to realize a larger movable change such as a movable accessory attached to a conventional writing instrument.

A display unit 7 is provided at an upper end of the shaft 4. The display unit 7 can print various character shapes as shown in the figure, and can describe various expressions such as slogans and advertisements. Since the display unit 7 of the present invention not only moves up and down but also rotates as will be described later, different notations are provided on the front and back surfaces, and visual changes can be made by rotating. A special design or the like that may be generated may be described. It goes without saying that the shape of the display unit 7 itself may be a character shape.

The vertical movement of the shaft 4 is performed by operating the operating lever 5 up and down. That is, the operating lever 5 protruding outside the writing cylinder 2 can be moved up and down along the vertical groove 8 formed in the writing cylinder 2, and the lower end of the operating lever 5 and the lower end of the shaft 4 can be moved. Since the shaft 4 is connected, the shaft 4 is moved in and out of the writing cylinder 2 with the operation of the operating lever 5.

The lower end of the shaft 4 is in contact with a spring 3 arranged in the writing cylinder 2 as shown in the figure, and the elasticity of the spring 3 provides a force for constantly lifting the spring 3 upward. is recieving. Therefore, when the operation of the operating lever 5 is not performed as described above, the shaft 4 is completely protruded to the outside, and the operating lever 5 is lowered to move the shaft 4 into the writing cylinder 2 as shown in FIG. It is necessary to apply a force opposing the elasticity of the spring 3 in order to immerse the spring. When the operation of the operating lever 5 is stopped, the lower end of the shaft 4 is pushed up by the elasticity of the spring 3, and it is natural that the shaft 4 returns to the state shown in FIG.

The above-described shaft 4 moves up and down through an opening 11 of a cover member 9 placed on the upper end of the writing cylinder 2. The shaft 4 is spirally wound around the shaft 4 and fixed. The wire 6 is regulated so as to pass through only the edge groove 11 formed at the edge of the opening 10, and the edge groove 11 has a guide function for the wire 6. Since the spiral wire 6 cannot move in and out of the writing cylinder 2 without passing through the edge groove 11, the shaft 4 rotates up and down with the up and down operation by the operating lever 5. It is possible to take complex movable changes that also perform

FIG. 2 shows a state in which the operating lever 5 is operated to push down the shaft 4 to the lowermost end in the writing cylinder 2 with respect to the state of FIG. Since the wire 6 is wound several times around the shaft 4, the shaft 4 moves up and down from the upper end to the lower end of the writing cylinder 2, so that several rotations are also performed. The display unit 7 attached to the camera also rotates several times. As described above, when the operation of the operation lever 5 is stopped, the display returns to the state shown in FIG. 1. In this case, the display unit 7 attached to the shaft 4 undergoes several reverse rotations to perform the operation shown in FIG. It will return to the state.

When the lower end portion of the shaft 4 reaches the lowermost end portion as shown in the drawing, the operating portion 13 for operating the writing portion 12 of the writing instrument 1 is pressed. Therefore, with such a configuration, the operation of moving the writing implement 1 into and out of the writing section 12 can be performed in conjunction with the up and down operation of the operating lever 5, thereby increasing the practicality. Since the operation of the writing unit 12 may be realized by a pressing operation on the operation unit 13, the writing implement 1 itself may be a ball-point pen, a mechanical pencil, or another similar operating device that allows such an operation. Anything that adopts the operational relationship may be used.

If the entire or appropriate part of the writing cylinder 2 is formed of a transparent plastic material or the like, the expansion and contraction of the spring 3 and the vertical rotation of the shaft 4 around which the wire 6 is wound in a spiral manner can be controlled from the outside. It can be observed and made more interesting to the user.

In the above description, the case where the wire 6 is employed as the convex portion has been described. It is possible to achieve the same technical effect as described above, and it is also possible to form the spiral-shaped convex portion from the beginning in a state of being integrated with the shaft 4. Is what you can do.

[0020]

[Effect of the invention]

 According to the present invention as described above, it is possible to cause a large rotational up-and-down movement of the shaft and the display unit connected to the shaft to be performed in accordance with an operation of protruding and retracting the writing unit. It offers new attractiveness not found in products, and its composition is relatively simple, so there is no danger of product costs increasing, and this is an industrially valuable idea.
