Description

[Detailed description of the device]

[0001]

[Industrial field of application]

 The present invention relates to a writing instrument with a seal, which includes a writing body in a front portion and a seal stamp detachably fitted in a rear portion.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a writing instrument with a seal in which a seal stamp is attached to the rear end of the writing instrument is known. In addition, a knock-type ball-point pen that consists of a cam groove, a knock rod, and a rotary cam member, and the rotary cam member is positioned at the forward / backward position in conjunction with the forward / backward movement of the knock rod, and the tip of the cursive body is projected and retracted from the tip of the shaft. Are known.

[0003]

[Problems to be solved by the device]

 However, since the conventional stamper has the seal stamped on the knock portion, the seal stamp protrudes from the rear end of the cap with the stamp face upward, and is covered with a cover to protect the stamp face. Therefore, since the cover is attached and detached each time the seal is stamped, it is not easy to use and there is a problem that the cover is easily lost. Further, there is a problem that the finger is soiled when the cover is attached and detached. Therefore, an object of the present invention is to solve the above drawbacks and problems.

[0004]

[Means for Solving the Problems]

 The writing instrument with a seal of the present invention devised to achieve the above object is equipped with a ball pen or a mechanical pencil in the front part and a storage case in the rear part, which is interlocked by moving the storage case back and forth. It is a writing instrument that has a writing tip with which the tip of a ballpoint pen is projected or retracted from the tip of the shaft, or the sharp core is extended, and the stamp is removably attached to the storage case. The seal unit is detachably connected to a seal unit with a print body that can be impregnated with ink, and the seal has the print surface of the print body facing downward, and the handle tip is appropriately locked to the storage case. The rear end of the handle is fitted into the state and serves as a knock portion for moving the storage case back and forth.

【Example】

 1 to 3 show an embodiment of the present invention. First, as shown in FIG. 1, the cap 1 has a step portion 22 at the tip of an inner hole whose rear end is open, and a clip 23 on the outer peripheral side surface. Further, a cam groove 3 is formed in the 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, which will be described later, is formed at the outer peripheral tip. There is. Further, a center shaft 25 is fitted or fixed to the portion of the front shaft portion 2 excluding the engaging portion 24.

A cam portion 5 formed at the tip of the knock rod 4 is fitted into the cam groove 3, and the knock rod 4 is fitted to the front shaft portion 2 so as to be movable back and forth. A rotary cam member 6 having a cam portion 7 that is in contact with the front end of the cam portion 5 is arranged so as to be in contact with the above-mentioned cam groove 3. The knock mechanism section having the above-described configuration is similar to the widely known Kahn-type knock mechanism. Further, behind the rotary cam member 6, a tubular shaft portion 26 having a closed rear end is extended, the shaft portion 26 is fitted in the central hole portion of the knock rod 4, and the rotary cam member 6 is knocked. An engagement portion 27 is formed between the outer peripheral portion of the shaft portion 26 and the center hole of the knock rod 4 so as to prevent the rod 4 from axially shifting and rotating freely within a proper range.

Further, a groove-shaped engaging portion 28 is formed on the outer peripheral portion of the rear end of the knock rod 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. . While the coil spring 8 is urged between the stepped portion 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 storage case 9 is fixed. Further, a rotation stopper is provided between the knock rod 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 rotational direction. (Not shown) Further, at the entrance of the inner peripheral portion of the storage case 9, there is formed a groove-shaped engaging portion 31 which is detachably engaged with a protruding engaging portion provided on a handle of a seal stamp which will be described later. . The groove and the protrusion may be replaced with each other in the engaging portions that engage with each other at the above-mentioned places.

The rear end of the writing body 10 such as a ballpoint pen is attached to the inner hole of the shaft portion 26 of the rotary cam member, and the rear end is brought into contact with the crimp 34 formed on the tube 33 of the writing spring 10. Is attached, and the front shaft 11 having the engaging portion 32 that elastically engages with the inner hole portion is fixed to the engaging portion 24 of the front shaft portion 2, and the front end of the return spring 12 is fixed. The cursive body 10 such as a ballpoint pen is always urged rearward by being brought into contact with the front step portion 35 of the front shaft 11. The front shaft 2 and the front shaft 11 may be fixed to each other by screwing.

Further, as shown in FIGS. 1 and 3, the seal stamp 15 is configured by detachably attaching a seal stamp unit 15 ′ to a handle 20. The handle 20 has an inner cylinder portion 36 having a slit 38 in a front inner hole and being appropriately elasticized, and a protrusion-like engaging portion 37 formed on the outer periphery of the front side thereof, and a rear end thereof. Is provided with a display plate 21 showing the name and the like of the seal stamp.

On the other hand, in the seal stamp unit 15 ′, the printing body 16 is placed on the front surface of the mounting base 19, the outside is covered with a cover 18, and the cover 18 is fixed to the front shaft portion of the mounting base 19. Further, the inner cylinder portion 36 of the handle 20 is fitted in the rear inner hole portion of the mounting base 19 so that the seal unit 15 and the handle 20 are connected. By the way, the printing body 16 is made of a printing material having a porous through hole and capable of being impregnated with 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 occlusion body and a cushion are provided between the printing body 16 and the front surface of the mount 19.

As described above, the seal 15 is fitted in the storage case 9 with the stamp surface 17 thereof facing downward, and the engagement portion 37 of the handle 20 is detachably attached to the engagement portion 31 of the storage case 9. Stop. In this case, the relationship between the grooves and the protrusions of the engaging portions may be changed.

[0012]

[Action]

 The writing instrument with a seal, which is an embodiment of the present invention, is configured as described above, and the seal 15 having the rear end as a knock portion is detachably attached to the storage case 9 to move the knock portion back and forth. Then, the writing tip portion 13 of the writing body 10 such as a ballpoint pen comes in and out from the tip end opening 14 of the tip shaft 11. In addition, the handle is picked, the seal is removed from the storage case 9, and a predetermined document is imprinted. In the case of a knock type mechanical pencil, the storage case is fixed to the rear end of the lead case that moves back and forth in order to feed the lead in conjunction with the chuck mechanism. Further, the handle 20 can be locked in the storage case 9 even when the seal stamp unit 15 'is not attached.

[0013]

[Effect of device]

 The construction and operation of the writing instrument with a seal according to the present invention are as described above. Since the printing surface is attached to the storage case with the printing surface facing downward, there is no need for a cover for protecting the printing body as in the conventional case, and the cover is attached and detached. It does not bother you and does not get your fingers dirty. There is also no problem of losing the cover. Furthermore, since the handle can be locked in the storage case even without the seal stamp unit, the user can purchase the writing instrument and attach a commercially available seal stamp unit if necessary, which gives the user the freedom of choice.
