TECHNICAL FIELD OF THE INVENTION
The present invention relates to a penetration mark attached to a shaft member such as a writing instrument.
[0002]
[Prior art]
A penetrating mark attached to a shaft member such as a writing instrument needs to be refilled with ink when the imprint becomes thin. Conventionally, when refilling the ink, the ink is dripped from the stamp surface side using a refill bottle or a refill ink cartridge having a sharpened point (for example, see Patent Document 1). However, such an ink replenishment method has a dissatisfaction that it takes too much time to fill the ink occluding member with ink. In addition, there is a possibility that the ink is easily spilled from the stamp surface to the surroundings, hands and clothes may be stained, and there is a dissatisfaction that the refilling operation is difficult.
[0003]
On the other hand, there is an ink storage device in which ink can be replenished by using a cartridge ink storage device (for example, see Patent Document 2). However, the use of the cartridge ink-occluding body increases the length in the axial direction, so that there is a space limitation when attaching to a shaft member such as a writing instrument. Further, when the cartridge ink occluding body is empty, it is necessary to remove the cartridge ink occluding body from the cartridge holder in order to replace the cartridge ink occluding body. There is also a problem that the finger gets dirty.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the embodiment shown in FIGS. 1 to 4 will be described. As shown in FIG. 1, the penetrating mark includes a printing body 1, a case 5, and a shaft member 6. In addition to the above, it is also possible to provide the print body holding ring 4 and the cap 7 (see FIG. 2).
[0017]
The printing body 1 can have a two-layer structure by laminating the ink occluding member 3 on the back side (rear side) of the stamp surface member 2. Note that other members can be laminated to form a multilayer structure.
[0018]
The stamp surface member 2 is a porous elastic body having continuous pores, and can be formed using a material such as silicon, NBR, or EBR. The ink occluding member 3 is formed of a porous elastic body having continuous pores such as PVF resin and sponge. The pores of the ink occluding member 3 are coarser than the pores of the stamp member 2, and the ink stored in the ink occluding member 3 can be transferred to the stamp member 2 by capillary action.
[0019]
The case 5 has a printing body housing cylinder 8 in the front half and a mounting cylinder 9 for the shaft member 6 in the rear half. The inside of the printing body housing tubular portion 8 and the mounting tubular portion 9 are open, and the rear end of the mounting tubular portion 9 is opened to form an ink supply port 10 (see FIG. 2). The printed body 1 is placed on the inner step 11 of the case 5 (see FIG. 2).
[0020]
As shown in FIG. 2, the print body holding ring 4 is placed over the print body 1 held by the print body housing cylinder 8 of the case 5, and the print body holding ring 4 is attached to the outer periphery of the print body housing cylinder 8. When the print body 1 is fitted to the print body, the print body 1 is prevented from falling out of the print body housing cylinder 8 by the print body holding ring 4. In addition, the printing surface 12 of the printing body 1 is exposed from the front opening of the printing body holding ring 4.
[0021]
The side surface of the printing body 1 contacts the inner surface of the printing body housing cylinder portion 8 of the case 5, and it is possible to provide a vertical groove-shaped concave portion 13 on the inner surface at a plurality of circumferential positions in the form of an internal gear. it can. When the print body 1 is stored in the print body housing cylinder 8, the side surface of the print body 1 is in a state of being cut into the recess 13 and the rotation of the print body 1 is prevented.

The effect is obtained. In addition, the concave portion 13 and the convex portion 14 do not always need to be provided at a plurality of positions, and the effect can be obtained by providing them only at one position. In the case of the conventional penetration mark, the measures for preventing the rotation of the printed body are insufficient, and when the stamp surface hits the paper surface at the time of stamping, there is a problem that the printed body rotates and the direction of the imprint is not constant. This problem can be solved by providing the convex portion 14.
[0023]
The case 5 is connected to the shaft member 6 by inserting the mounting cylinder 9 at the rear half thereof. If the internal space of the mounting cylinder portion 9 is sealed in this state, the air in the internal space expands due to a rise in temperature and the like, and the pressure increases, causing a pressure difference between the inside and outside. When such a pressure difference occurs, there is a problem in that the amount of the ink flowing out varies, the shading appears on the imprint of the seal, the image becomes unclear, and the life of the seal is shortened.
[0024]
In order to solve this problem, a ventilation groove 15 for opening the internal space of the mounting cylinder 9 of the case 5 to the outside can be provided. The ventilation groove 15 can be formed in the mounting cylinder 9 and / or the side wall of the shaft member 6. . Although the ventilation groove 15 is formed in the side wall of the mounting cylinder 9 in the drawing, it may be provided in the side wall of the shaft member 6, or may be provided in both.
[0025]
When the print cylinder 1 is used for a long time while the mounting cylinder 9 of the case 5 is connected to the shaft member 6 such as a writing instrument, and the print body 1 runs out of ink, the ink is replenished to the ink storage member 3 of the print body 1. There is a need. The ink is replenished in the following procedure.
[0026]
First, the mounting cylinder 9 of the case 5 is removed from the shaft member 6 such as a writing instrument. Next, the ink supply port 10 of the case 5 is turned upward. Then, ink is dropped from an ink supply bottle or the like. The dropped ink is directly absorbed by the ink occluding member 3 without passing through the stamp surface member 2. Therefore, the ink replenishment time can be reduced.
[0027]
By making the case 5 detachable from the shaft member 6, the case 5 may come off the shaft member 6 unexpectedly. In order to prevent this, it is preferable that the case 5 can be locked to the shaft member 6.

Then, the case 5 is rotated with respect to the shaft member 6 in a state where the engagement protrusion 18 reaches the end of the vertical groove portion 16, and the engagement protrusion 18 is fitted into the horizontal groove portion 17. Then, the case 5 is further rotated to be moved to the depth of the lateral groove 17. As a result, the engagement projection 18 is engaged with the lateral groove 17 to be locked, so that the case 5 does not come out of the shaft member 6 unintentionally. Then, in order to remove the case 5 from the shaft member 6, the case 5 may be rotated in the opposite direction to the shaft member 6, and then the case 5 may be removed in the axial direction.
[0030]
In addition, since the rear end of the fitting cylindrical portion 9 is opened to form an ink replenishing port 10, when the sign surface 12 is directed upward, ink flows from the ink occluding member 3 of the printing body 1 into the shaft member 6. There is a risk of falling.
[0031]
Therefore, in order to solve this problem, a partition 19 can be provided inside the shaft member 6 as shown in FIG. The partition 19 is arranged so as to cover the ink supply port 10 of the case 5.
