Means for Solving the Problems The writing implement with seal of the present invention devised to achieve the above-mentioned object is provided with a ballpoint pen or a mechanical pencil in the front part, a storage case in the rear part, and a storage case. It is a writing implement with a ballpoint pen writing tip protruding and retracting or a sharp lead coming out of the shaft tip by moving forward and backward, and a seal stamp is detachably attached to the storage case. A seal unit having a printed body having a through hole and capable of impregnating with ink is provided so as to be detachably connected to the handle, and the seal is provided with the printed surface of the printed body facing downward, and The rear end of the handle is formed as a knock portion for moving the storage case back and forth by being appropriately fitted to the storage case in a locked state.

[0005]

1 to 3 show an embodiment of the present invention. First, as shown in FIG. 1, the cap 1 has a stepped portion 22 at the end of an inner hole whose rear end is open, and a clip 23 is provided on the outer peripheral side surface. Further, a cam groove 3 is formed in an inner hole of the front shaft portion 2 extending forward from the step portion 22, and an engaging portion 24 for detachably fixing a front shaft described later is formed at an outer peripheral end. . A center shaft 25 is fitted or fixed to a portion of the front shaft portion 2 other than the engaging portion 24.

A cam portion 5 formed in front of the knock bar 4 is fitted in the cam groove 3 so that the knock bar 4 is fitted to the front shaft portion 2 so as to be movable back and forth. Cam part 5
A rotary cam member 6 having a cam portion 7 which is in contact with the tip of the cam groove 3 is also provided so as to be in contact with the cam groove 3. The knock mechanism having the above-described structure is formed in a manner similar to that widely known as a Kahn-type knock mechanism. A cylindrical shaft 26 having a rear end closed behind the rotary cam member 6.
Is extended, the shaft portion 26 is fitted in the center hole of the knock bar 4, and the rotating cam member 6 is axially shifted with respect to the knock bar 4 within an appropriate range and is free to rotate. An engaging portion 27 for retaining is formed between the outer peripheral portion and the center hole of the knock bar 4.

A groove-like engaging portion 28 is formed on the outer peripheral portion of the rear end of the knock bar 4, and a protruding engaging portion 30 is formed on the inner surface of the front end portion 29 on the front surface of the storage case 9. . With the coil spring 8 being biased between the step 22 of the cap 1 and the front surface of the storage case 9, the engaging portion 30 is locked to the engaging portion 28 by mutual elastic deformation, and the knock bar 4 The storage case 9 is fixed. Further, a detent is provided between the knock bar 4 and the storage case 9 or between the storage case 9 and the inner hole of the cap 1 so as to be integrated in the rotation direction. (Not shown) Further, a groove-shaped engaging portion 31 is formed at an inner peripheral portion entrance of the storage case 9 so as to be detachably engaged with a protruding engaging portion provided on a seal handle described later. . Incidentally, the engaging portions that engage with each other at the above-mentioned locations may be replaced with grooves and protrusions.

A rear end portion of the writing body 10 such as a ball-point pen is mounted in an inner hole of the shaft portion 26 of the rotary cam member, and a rear end abuts a crimp 34 formed in the tube 33 so that the return spring 12 is moved. The engagement portion 24 of the front shaft portion 2 is attached to the engagement portion 3 which elastically engages with the inner hole portion.
2, the front end of the return spring 12 is in contact with the step 35 on the front side of the front shaft 11, and the writing body 10 such as a ballpoint pen is constantly urged rearward. The front shaft 2 and the front shaft 11 may be fixed to each other by screwing.

As shown in FIG. 1 and FIG.
Is constructed by detachably attaching the seal unit 15 # to the handle 20. The handle 20 has a slot 38 in a front inner hole, and an inner cylinder portion 36 appropriately elastically formed is formed. A protruding engagement portion 37 is formed on an outer peripheral portion of the handle 20 and a rear end thereof. A display plate 21 indicating the name of the seal and the like is provided.

On the other hand, the seal unit 15 ｀ is
A print body 16 is placed on the front surface of the cover 9, and the outside is covered with a cover 18, and the cover 18 is fixed to a front shaft portion of a mount 19. In addition, the handle 20 is provided in the rear inner hole of the mounting base 19.
Of the seal unit 15 ｀ and the handle 2
0 is combined. The printing body 16 is made of a printing material having porous through holes and capable of impregnating ink, and a printing surface 17 such as a name is engraved on the front surface of the printing body 16. If necessary, an ink occluding body and a cushion are provided between the printing body 16 and the front surface of the mounting table 19.

As described above, the seal 15 is fitted into the storage case 9 with the seal 17 facing downward, and the engaging portion 37 of the handle 20 is detachably engaged with the engaging portion 31 of the storage case 9. Stop. In this case, the relationship between the grooves and the protrusions may also be interchanged in the engagement portion.

[0012]

The writing instrument with a seal as an embodiment of the present invention is constructed as described above, and a seal 15 having a knocking portion at the rear end is removably mounted in the storage case 9, and the knocking portion of the knocking portion is provided. The writing tip 13 of the writing body 10 such as a ball-point pen by back and forth movement
Protrudes and retracts from the distal end port 14 of the front shaft 11. In addition, the handle is picked up, the seal is pulled out of the storage case 9, and a predetermined document is stamped. In the case of a knock mechanical pencil,
The storage case is fixed to the rear end of the lead case which moves back and forth in order to extend the lead in conjunction with the chuck mechanism. (Not shown)
The handle 20 can be locked to the storage case 9 even when the seal unit 15 'is not attached.

[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 since the seal face is attached to the storage case with the seal surface facing downward, a cover for protecting the printing body as in the related art is not required. There is no need to bother attaching and detaching the cover, and to keep the fingers dirty. Also, there is no problem of losing the cover. Further, since the handle can be locked to the storage case even when there is no seal unit, there is an effect that a user can purchase the writing implement and attach a commercially available seal unit as necessary, thereby giving a degree of freedom in selection.
