[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a writing implement with a seal having a writing body on the front side and a seal on the rear side.

[0002]

2. Description of the Related Art Conventionally, there has been provided a knock mechanism comprising a cam groove, a knock bar and a rotary cam member. Knock-type ballpoint pens that appear and disappear from the front are known. Further, there is known a seal unit which is detachably attached to a knock mechanism directly or via a holder and is positioned so as to protrude from a rear end of a shaft cylinder.

[0003]

However, in the conventional one, when the user grips the back of the barrel and makes a seal, the knocking mechanism interlocks and the writing tip part is inadvertently protruded or retracted from the tip end of the front spindle. Is set to Then, this invention aims at solving such a defect.

[0004]

In order to achieve the above-mentioned object, a writing implement with a seal of the present invention devised to achieve the above-mentioned object has a knock mechanism provided in an inner hole of a shaft cylinder and is interlocked with the knock mechanism. The stamp is provided with the stamp face protruding from the rear end of the barrel, and a writing body such as a ballpoint pen is arranged in front of the knock mechanism to cover the stamp face and knock when the knock cover is fastened. This is a writing instrument whose writing tip is locked in a protruding state from the tip opening of the barrel by actuation, and the writing tip is locked in a protruding state even when the stamped surface advances flush with the rear end of the barrel during stamping. Knock stroke is set so as not to be performed.

FIG. 1 shows an embodiment of the present invention. First,
As shown in the figure, the cap 1 is a cylindrical body, and is integrally provided with a front shaft portion 2 having an engaging portion 35 in front of the step portion 11 and a rear shaft portion 3 protruding inside the cylindrical body. A step 12 and a cam groove 3a are formed at the rear end in the rear shaft 3. A clip 13 is provided on the rear side surface of the cap 1. In addition, the cam portion 5 formed in front of the knock bar 4 is fitted into the cam groove 3a so that the knock bar 4 can be freely moved back and forth with respect to the rear shaft portion 3. A rotating cam member 8 having a cam portion 9 that is in contact with the tip of the cam portion 5 is also provided so as to be in contact with the cam groove 3a .

[0006] The knock mechanism having the above-described structure is formed in a manner similar to that widely known as a Kern type knock mechanism. At the rear of the rotary cam member 8, a cylindrical shaft portion 8 # whose rear end is closed is extended, and the shaft portion 8 # is a center hole of the shaft portion 6 which also extends rearward of the knock rod 4. The rotary cam member 8 is fitted to the portion, and the rotating cam member 8 is axially shifted with respect to the knock bar 4 in an appropriate range, and is rotatable freely between the outer peripheral portion of the shaft portion 8 # and the center hole of the knock bar 4. And an engaging portion (not shown) for preventing the coming off, which is regulated by the contact between the convex portion and the convex portion. A groove-shaped engaging portion 7 is formed on the outer peripheral portion of the rear end of the shaft portion 6 of the knock bar 4.

The storage case 15 is provided with an engagement cylinder 16 at the front center of the flange 20, and is provided at the tip of the engagement cylinder 16 in opposition to a slit 22 provided at a predetermined position of the partition 21. Is provided with an engaging portion 14 having a projecting step.
In addition, a rib-shaped stepped portion 20 # is provided at a required portion outside the engagement cylinder portion 16 and in front of the flange portion 20. Also, the collar 20
At the rear end, there is an inner cylindrical portion 17 at the center and an outer cylindrical portion 18
And an engaging portion 19 is provided on a side surface of the outer cylindrical portion 18 and is formed of an integral resin molded product.

As described above, the storage case 15 is inserted into the inner hole of the cap 1, and the coil spring 10 is inserted between the step 11 of the cap 1 and the step 20 # of the storage case 15.
The engagement portion 7 of the knock bar 4 is locked to the engagement portion 14 of the engagement cylinder portion 16 by elastic deformation between the engagement portions 14 of the engagement cylinder portion 16 so that the knock bar 4 and the storage case 15 are fixed. You. The shapes of the engaging portion 14 and the engaging portion 7 can be interchanged.

A rear end of a writing body 39 such as a ball-point pen is mounted in an inner hole of the shaft portion 8 # of the rotary cam member 8, and a rear end of the writing body 39 is brought into contact with a crimp 41 formed in the tube 40 so that a return spring is formed. A front shaft 34 having an uneven engaging portion 36 elastically engaged with the inner hole is fixed to the engaging portion 35 of the front shaft portion 2 of the cap 1. The front end of the return spring 43 is in contact with the rib-shaped step portion 38 at the front of the front shaft 34, and the writing body 39 such as a ballpoint pen is constantly urged backward.

In the seal unit 26, a printing body 27 is placed on the rear surface of a rear shaft portion 32 of a mounting table 30, and the outside is covered with a cover 29, and the cover 29 is fixed to the rear shaft portion 32. Further, the inner cylindrical portion 17 of the storage case 15 is fitted into the hole of the front shaft portion 31 of the mounting base 30 by frictional engagement as appropriate, and the seal unit 26 holds the seal surface 28 at the rear end of the storage case 15 with the cap 1. From the rear end. In addition, the seal unit 26 can be mounted by engaging the front shaft portion 31 of the mounting table 30 with the inner hole of the outer cylindrical portion 18 of the storage case 15. The printing body 27 is made of a printing material having a porous through hole and capable of impregnating ink, and a printing surface 28 such as a name is engraved on the front surface of the printing body 27. If necessary, an ink occluding body and a cushion are provided between the printing body 27 and the rear end of the mounting table 30.

On the rear end of the cap 1, a knock cover 23 having an engaging portion 25 for detachably engaging with an engaging portion 19 provided on the outer cylindrical portion 18 of the storage case 15 covers the stamp surface 28. And fitted. In this case, the engaging portion is also formed of a groove and a projecting portion, and the relationship may be interchanged. A transparent crown 24 is fixed to the rear end of the knock cover 23. In addition, a display board or the like (not shown) on which the name of the seal is written is inserted into the gap 24 # formed at this time.

[0012]

The writing instrument with the seal stamp according to the embodiment of the present invention is constructed as described above, and the stamped surface 28 is provided so as to protrude from the rear end of the cap 1 so that the stamped surface is in contact with the rear end of the cap at the time of stamping. When the writing tip 42 is pressed to the same level, the writing tip 42 projects from the tip end port 37 of the tip shaft 34, but the stroke of the knock mechanism is set so as not to be locked in that state. When the knock cover 23 is fixed, the writing tip 42 comes out of the tip opening 37 by the knocking operation. Further, since the knock cover 23 is fitted to the storage case 15 in a non-contact state with the seal unit 26, there is no problem that the seal unit 26 is inadvertently removed when the knock cover 23 is detached.

[0013]

[Effect of the Invention] The construction and operation of the writing implement with a seal of the present invention are as described above, and there is no problem that the tip of the writing is inadvertently protruded and retracted during knocking. Further, there is an effect that there is no problem that the seal stamp unit is accidentally detached from the cap when the knock cover is detached.
