[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a so-called seal-equipped writing instrument equipped with a seal using a printed body made of a porous seal material having countless continuous pores.

[0002]

2. Description of the Related Art Conventionally, it is not necessary to use a printing material formed of a porous stamping material having an infinite number of continuous pores such as sponge rubber so as to absorb ink, and to attach it to vermilion every time it is used. A writing implement with a seal is known in which a seal is attached to the rear end of a shaft. However, if the printing surface of the seal is exposed, this type of writing instrument with a seal may cause scratches on the printing surface, adhere to dust, or dry the ink. Therefore, not only is it troublesome to attach and detach the cap, but also there is a problem that the cap is lost, and there is a problem that the hand is erroneously stained at the time of attachment and detachment.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an inexpensive writing instrument with a seal which has solved the above-mentioned problems.

[0004]

In order to achieve the above object, a writing instrument with a seal of the present invention devised to achieve the above object is provided with a lid for storing a seal in an inner hole at a rear end thereof, and a cover for closing an opening. An elastic piece provided with a spring property on the side surface of the shaft and a hinge are formed integrally at an appropriate position and provided elastically rotatably, and the cap is fitted on the outer periphery of the rear portion of the shaft so as to be axially movable, and the cap is The inner surface of the lid is expanded while contacting the corners of the seal, so that the printed body is exposed from the opening and can be stamped.

[0005]

1 and 2 show an embodiment of the present invention. First, as shown in FIG. 1, a seal 5 stores a printing body 6 formed of a porous printing material having an infinite number of continuous ventilation holes such as sponge rubber so as to absorb ink, and stores the ink in the printing body 6. A seal (not shown) is fixed to the leg 7 with a cover, and the seal 7 has the leg 7 detachably fitted to the shaft 31 at the rear end of the rear shaft 1. A slit (not shown) is formed on the side surface near the opening 21 at the rear end of the cap 4 to provide a resilient piece 9 having a spring property.
The hinge 10 is rotatably bridged between the cap and the cap 4.
And 11, and hinges 12 are formed rotatably on both sides of the connection portion. As described above, the lid 8 is provided so as to freely open and close in a state where the opening 21 of the cap 4 is provided with the spring property, and the lid 8 is configured to always shield the opening 21.

The cap 4 is fitted on the outer periphery of the rear shaft 1 so as to be axially movable, and two locking grooves 19 and 20 are formed on the outer periphery of the rear shaft 1 by protrusions 23 and 24. And the projection 23,
Between the grooves 24, grooves 25 are formed. Opposed thereto, a protruding locking portion 14 is formed in the inner hole of the cap 4.

In the state shown in FIG. 1, the locking portion 14 is engaged with the locking groove 19 of the rear shaft 1. Also, the cap 4 moves with the rear shaft 1, but is blocked in the rotation direction. In order to reliably prevent the rotation direction, the inner peripheral portion of the cap 4 and the outer peripheral portion of the rear shaft 1 are appropriately provided with rotation stopping means. (Not shown)

In the writing implement with seal of the present invention, the cam shaft 17 is provided on the inner diameter of the rear shaft 1, and the shaft 31 at the rear end is provided.
A flange portion 27 having a hole is formed integrally with the inner diameter portion. On the other hand, in the two guide grooves 30 formed in the guide cylinder 15, correspondingly, the sliding pieces 16
The two ball-point pen writing bodies 32 and 33 to which are attached are biased by a return spring 34 so as to be pulled rearward. Further, the forward end portion of the guide tube 15 is detachably attached to the front shaft 2 and is joined to the joining portion 28,
9 are provided. (Mutual rotation stop shape, protrusion,
Retaining shape with groove. Screwing is also possible. )

The flange 2 is provided at the rear end of the guide cylinder 15.
A fixing portion 26 having a collar portion which is fitted into the hole of No. 7 and retained and locked is integrally formed, and the guide cylinder 15 and the rear shaft 1 are prevented from coming off, so that the guide cylinder 15 and the rear shaft 1 can be freely rotated within an appropriate range in the rotation direction. Has become. That is, a portion (not shown) is provided between the brim portion 27 and the fastening portion 26 to prevent the cap 4 from rotating with respect to the guide cylinder 15 in an angle range of approximately 180 degrees.
In order to prevent the guide cylinder 15 and the rear shaft 1 from coming off, a ring-shaped projection is provided on the outer peripheral portion of the front end of the guide tube 15 and a ring-shaped groove is provided on the inner peripheral portion of the rear shaft 1 so that they are fitted by elastic deformation. It can also be configured to be. By rotating the rear shaft 1, that is, the cap 4 with the rotation stopped, with respect to the front shaft 2, the ballpoint pen writing bodies 32 and 33 are configured to alternately protrude and retract from the front end hole 3 of the front shaft 2. The writing implement with a seal is such that the cover is opened and closed to expose the printed body by moving the cap fitted on the rear end of the shaft, and the specification and structure of the writing implement are not limited.

[0010]

The writing implement with a seal according to the present invention is constructed as described above. When not in use, the lid 8 covers the printing body 6 as shown in FIG. At the time of stamping, when the cap 4 is moved forward with respect to the rear shaft 1, the locking portion 14 elastically rides over the projection 23 and separates from the locking groove 19 to release the groove 2.
After that, the locking portion 14 elastically rides over the protrusion 24 and engages with the locking groove 20. At this time, the inner surface of the lid 8 is expanded while contacting the corner 22 of the seal 5 avoiding the printed body 6, and the printed body 6 is exposed from the opening 21 of the cap. (See FIG. 1) In this state, even if the cap 4 is gripped and stamped, the cap 4 is prevented from shifting along the rear shaft 1 by a suitable drag. When the print body 6 is to be stored again, the cap 4 may be axially moved rearward with respect to the rear shaft 1 by a force greater than the engaging force.

[0011]

[Effects of the Invention] The construction and operation of the writing implement with seal of the present invention are as described above. There is a concern that the cap is attached and detached and lost every time the seal is applied, as in the case where the printing surface is covered with a conventional cap. It can be used without any problems such as accidentally getting your hands dirty when attaching or removing the cap, and the printing surface is covered with the lid when not in use. It is possible to provide a writing instrument with a seal that is extremely easy to use without problems such as ink drying and ink drying. In addition, since the lid is formed integrally with the elastic piece and the hinge by imparting spring properties, a complicated cap structure can be simplified and provided at a low cost.
