Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument with a seal stamp that can be used as both a writing instrument and a seal stamp.

[0002]

[Prior art]

 Since writing instruments and stamps are often used in the same scene, such as writing and stamping on documents, various writing instruments with stamps have been proposed that can be used both as writing instruments and stamps by adding a stamp to the writing instrument. , Has also been put to practical use.

[0003]

[Problems to be solved by the device]

 In any case, the conventional writing instrument with a seal has a seal attached to the cap of the writing instrument or the end of the barrel, and there is no direct relationship between the writing function and the stamping function. By the way, the stamp attached to the writing instrument is made of a porous material, rather than using ink, and is imprinted with ink containing ink, but the ink required for one imprinting is imprinted. Although the amount is small, the printing plate is small and the ink containing capacity is small, so it is often necessary to replenish the ink if the stamp is used frequently. In other words, when the ink contained in the stamp is exhausted, it is necessary to remove the seal from the writing instrument and take out the ink from the ink bottle with a dropper to replenish it. Therefore, there is a problem that the ink supply operation is complicated.

Therefore, an object of the present invention is to provide a writing instrument with a seal stamp which is easy to use and does not require ink replenishment operation to the stamp.

In order to achieve such an object, the writing instrument with a seal of the present invention is an ink cylinder in which a tip rotatably held in a state where a ball is elastically forwarded by a spring is arranged in a shaft cylinder. The ball-point pen fixed to the tip opening of the and the holder holding the stamp and the ink relay core are composed of a stamp that is movably arranged on the front shaft that is detachably connected to the barrel, and presses the stamp when stamping. Then, the holder retracts and the relay core comes into contact with the tip of the chip, so that the ink in the ink cylinder is supplied to the stamp through the chip and the relay core.

[0006]

[Action]

 That is, if the tip shaft is removed from the barrel, it can be used as a ballpoint pen, but when using a seal, the holder holding the stamp and the ink relay core retracts and the relay core comes into contact with the tip of the chip, Since the ink is supplied to the stamp through the tip and the relay core, that is, the ballpoint pen automatically performs the ink refilling function, the ink refilling operation to the stamp is unnecessary.

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a protrusion 11 is formed inside the tail end of the barrel 1, and an air hole 12 is formed in the center of the protrusion 11. The ink cylinder 2 arranged in the shaft cylinder 1 has its tail end portion fitted and fixed to the projection 11, and the tip 3 is attached to the tip opening of the ink cylinder 2. A backflow preventing agent 21 is arranged in the ink cylinder 2, and ink is filled between the tip 3 and the backflow preventing agent 21. When the ink is consumed, the backflow preventive agent 21 advances accordingly.

The tip 3 is formed of stainless steel in a bullet shape, and a ball house at the tip of the tip 3 has, for example, a cemented carbide ball 31 having a diameter of 1.0 mmφ, a part of which is exposed from the tip of the tip 3. It is held in a freely rotatable state when it is taken out. A spring 32 having a small spring force is arranged in the chip 3, and the spring 32 repels the ball 31 to press it against the inward tip edge 33 of the tip 3 to bring the ball 31 and the tip edge 33 of the tip 3 into contact. Constitutes the valve mechanism. Therefore, when not in use, the valve mechanism is closed so that the ink does not flow out from the tip of the tip 3. In this way, the shaft cylinder 1, the ink cylinder 2 filled with ink, the tip 3 rotatably holding the ball 31 and the like constitute a ballpoint pen.

A front shaft 4 is screwed onto the shaft cylinder 1, and the shaft cylinder 1 and the front shaft 4 are detachably connected. The holder 5 is arranged in the front shaft 4 so as to be movable back and forth, but a spring 51 is arranged between the holder 5 and the front shaft 4, and the holder 5 is elastically bulged forward.

A stamp 6 made of a porous material and having a name and the like printed on the front surface is fixed to the holder 5 by a fixed tube 52, and an ink relay core 61 is arranged behind the stamp 6, and an ink relay core 61 is provided. Is covered with sponge 62. The tail end face of the ink relay core 61 and the tip end of the chip 3 are spaced by about 2 to 3 mm. In addition, a seal cap 41 is fitted on the front end of the front shaft 4. In this way, the holder 5 holding the stamp 6 and the ink relay core 61, the front shaft 4, and the like constitute a stamp, which is detachably attached to the ballpoint pen.

When using the stamp, however, as shown in FIG. 2, the stamp cap 41 may be removed and the stamp 6 may be pressed against the paper surface. At this time, the holder 5 causes the spring 51 to spring. The rear end surface of the ink relay core 61 comes into contact with the tip of the tip 3 against the resilience of the ink. Therefore, the ball 31 protruding from the tip 3 retracts and moves away from the leading edge 33, so that the valve mechanism composed of the ball 31 and the leading edge 33 opens, and the ink in the ink cylinder 2 is printed through the tip 3 and the relay core 61. Is supplied to. In other words, the ink is automatically replenished to the stamp 6 every time the ink is consumed by the imprinting, so that the ink replenishing operation to the stamp 6 is not necessary, and the stamp is extremely easy to use. When used as a writing instrument, the tip shaft 4 may be removed from the barrel 1 and can be used as an ordinary ballpoint pen.

[0012]

[Effect of device]

 As described above, the writing instrument with a stamp of the present invention can be used as a ballpoint pen by removing the tip shaft from the barrel, but when using the stamp, the holder holding the stamp and the ink relay core is retracted and relayed. Since the core comes into contact with the tip of the chip and the ink inside the ink cylinder is automatically supplied to the stamp through the chip and the relay core, there is no need to refill the stamp with ink and it is easy to use. It can be a good writing instrument with a seal stamp.
