Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink stand for a rotary rubber stamp with a stamping aid. That is, a plurality of endless rubber band stamps having a stamp surface portion such as letters and numbers on the outer peripheral surface are arranged in a rotatable manner, and ink is applied to the character portion of the stamp surface portion which is below the lower horizontal plate for the stamp surface. For a rotary rubber stamp that can be attached and stamped and provided with a stamping assisting part to make the imprint at the time of stamping clear and accurate, always use an appropriate amount on the stamping face (specifically, on the character part of the stamping face) The present invention relates to an ink stand which can be impregnated with the ink.

[0002]

2. Description of the Related Art Generally, as described above, a rotary rubber stamp (also referred to as a rotary rubber stamp) is an endless rubber band stamp having a stamp surface portion formed with letters, numerals, and the like (hereinafter referred to as character portions) on an outer peripheral surface. A plurality of tubes are arranged side by side so that they can rotate independently,
By rotating the band rotating disk, desired characters and the like are moved to the lower side of the lower stamping horizontal plate, and ink is applied thereto and stamped (for example, Utility Model Application Advertising 27-6).
No. 406 and Japanese Utility Model Application Laid-Open No. 51-147512).

[0003] In the conventional rotary rubber stamp, a stamp surface is pressed against a stamp base in advance for each stamping, and ink is adhered to the stamp surface (more precisely, a character portion of the stamp surface), and then stamped. Was. However, when it is necessary to repeatedly apply the same seal imprint, if the ink is applied once and the seal is continuously imprinted, the seal imprint becomes gradually thinner, and only the fifth to sixth times can be read. In order to repeatedly imprint a clear imprint, it is necessary to attach ink to the imprint surface portion each time imprinting is performed, which greatly reduces office work efficiency.

[0004] Therefore, as for the rotary rubber stamp, similarly to the rotary data stamp (rubber stamp capable of simultaneously imprinting a company name, a section name or the name of a person in charge and the date), the stamp face portion is ink-impregnated (penetration type). For example, NBR (nitrile butadiene rubber) or another ink having a large ink impregnating property (penetrability) may be used to impregnate the stamp face with ink. was there.

However, when the ink impregnating property is increased, the hardness of the rubber material on the stamp face is inevitably small and soft, and the "stiffness" of the stamp face is weakened. Therefore, the strength of the force applied at the time of imprinting and the peculiarity of the hand are transmitted to the stamp face as it is, and the imprint becomes uneven or the difference in shading tends to occur. Also, if a strong force is applied at the time of imprinting, the impregnated ink will be pushed out more than necessary, and the ink will be applied too much to the document, the smudge will be blurred and the extra ink will touch other things, Ink was also applied to places other than the seal.

[0006] Furthermore, since the stamp face is soft and the "stiffness" is weak, the impregnated ink is pushed out more than necessary by one stamping, and the number of times that the stamp can be repeatedly stamped is greatly reduced. At times, when the stamp surface is compressed, the seat portion without characters or the like in the stamp surface is more likely to come into contact with the document, and the ink of that portion adheres to the document and stains the seal.

[0007] It is supposed that the stamp has a function corresponding to the stamp, so that the lower end edge is slightly above the lower end face of the stamp face portion on the lower side of the stamp face horizontal plate near the lower part of the rotary rubber stamp. Some have a cover plate or a protective case that is considered to have the function of an auxiliary part (for example,
JP-A-4414, JP-A-63-166454).

However, when the stamp face is pressed against the stamp base when the stamp face is pressed against the stamp base, the stamp face contacts the pad, and the cover plate and the protection plate are protected. The lower edge of the case contacts the pad, and the ink adheres to the lower edge. For this reason, at the time of stamping, the stamped face portion comes into contact with the document or the like, and at the same time, the lower edge of the cover plate or the protective case also contacts the document or the like, and unnecessary ink adheres to the document or the like.

In order to solve the problem, there is a device devised by the same inventor / applicant as the present application. This is a rotary rubber stamp with a cap that also serves as an ink stand. A skirt portion (hereinafter referred to as a stamping assist portion) is provided near the lower portion of the frame plate on both sides as a square tubular shape and a stamp surface portion is exposed from a lower opening. The stamping assisting portion is provided so that the lower edge of the opening is slightly above the lower end of the stamping portion below the stamping horizontal plate, and a pad is provided at the inner part inside the recess of the cap. Is smaller than the lower end surface of the stamping portion of the rubber band mark, but smaller than the lower end edge of the opening of the stamping assisting portion, and the lower end edge of the stamping assisting portion is formed around the pad when the cap is engaged. Is formed in such a way that the surface becomes floating (refer to Japanese Patent No. 2994629).

[0010] Thus, even though the stamp face is a soft rubber material having a large ink impregnating property, the imprint is uniform and clear without any difference in shading irrespective of the strength of the imprinting force or the habit of the hand.
Even if the force at the time of imprinting is strong, the ink is not pushed out excessively, the imprint does not stain or bleed, the number of times that continuous imprinting can be performed is increased, and office efficiency is improved. And the lower edge of the cover plate / protective case does not abut on documents or the like, so that unnecessary adhesion of ink can be prevented.

However, in the above-mentioned rotary rubber stamp with a cap, since the stamping assisting portion is formed in a rectangular cylindrical cross section, there are many types of stamping assisting portions to cope with various kinds of rotary rubber stamps including specially ordered products. Has to be manufactured and kept in stock.

Therefore, there is a rotary rubber stamp with an ink stand newly created by the same inventor / applicant as the present application. This consists of a rotary rubber stamp and an ink stand with a pad on the inner bottom.The rubber band stamp has a large stamping surface with high ink impregnating properties. A stamping assisting portion having a concave portion capable of engaging the folded pieces on both sides of the horizontal plate 3 or a front and rear edge portion having a lower end edge other than the front end edge and the rear end edge and having a front and rear width slightly larger than the front and rear width of the pad of the stand. Attach each stamping assisting part with a notch so that the lower edge is slightly above the lower end face of the stamping part that is below the horizontal plate for stamping, while the stand is engaged with the stamping assisting parts on both insides. Possible voids are formed or the width of the pad is such that both side edges are close to the inner surfaces of both sides of the recess 13 (see Japanese Patent Application No. 11-325127).

As a result, the stamp face is made of a soft rubber material having a high ink impregnation property, but the imprint is uniform and clear without any difference in shading irrespective of the strength at the time of stamping or the habit of the hand.
Even if the force at the time of imprinting is strong, the ink is not pushed out excessively, the imprint does not stain or bleed, and the number of times that continuous imprinting can be performed is increased to improve office efficiency. It does not come into contact with other parts, prevents unnecessary ink from adhering to the lower edge of the cover plate or protective case, and also accurately and clearly stamps plastic films and other slippery objects, and seals only one character. It is no longer necessary to manufacture and inventory so many types of stamping auxiliary parts for various types of rotary rubber stamps that can be stamped and include specially ordered items.

[0014]

However, it has been found that the rotary rubber stamp with the ink stand still has problems. As mentioned above, the strength of the stamping force and the habit of the hand could be solved by a rotary rubber stamp with an ink stand with the stamping assist part, but the pad of the stand was impregnated with the ink to impregnate the ink surface. At the time of pressing, if the force is too large, a large amount of ink will penetrate into the impregnated stamp face, and sometimes the ink may sometimes come out too much at the time of the first stamping.

That is, the rotary rubber stamp with the ink stand has a stamp face portion formed of a rubber material having high ink impregnation and permeability so that the same stamp can be continuously and repeatedly imprinted. In order to do so, the above-described stamping assisting section is provided. Nevertheless, at the time of the first imprinting, there is a problem that sometimes the ink is excessively printed so that the shadow becomes unclear or blurs and becomes dirty.

At first, the cause of the above-mentioned phenomenon was not clearly understood even though the seal assisting portion was provided. However, when examined in detail, if the force is too large when pressing the pad to impregnate the ink with the ink, the ink impregnation
The stamped surface made of a highly permeable rubber material is strongly pressed into the pad surface, so that a large amount of ink is impregnated into the stamped surface, and the ink that has been excessively impregnated into the stamped surface during the first stamping is pushed out and imprinted. Was found to be smeared or smudged.

Further, the present invention is not limited to the rotary rubber stamp provided with the stamping assisting portion, but if the stamp surface portion is repeatedly pressed against the pad with a large force, the pad is pushed to extend in the lateral direction, and the planar state deteriorates. There has been a problem that the contact with the stamp surface becomes uneven, and a clear seal cannot be imprinted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems that occur with a rotary rubber stamp, particularly a rotary rubber stamp with a stamping assist portion. That is, the main object of the present invention is that even if the pressing force of the stamping surface portion against the pad of the stand is too large, the ink is not impregnated in a large amount, the ink does not come out too much at the time of the first stamping, and the pad is deformed in the lateral direction to be in a flat state. It is an object of the present invention to provide an ink stand for a rotary rubber stamp with a stamping assisting portion, which can always stamp a clear stamp without preventing deterioration of the stamp.

[0019]

The first aspect of the ink stand for a rotary rubber stamp with a stamping assisting portion according to the present invention is that the stamp surface portion 3 of each endless rubber band stamp 2 is formed of a material having a high ink impregnating property. At the same time, a stamping assisting portion 6 having a plate shape or a quadrangular cross section is provided on each lower side surface of both side frame plates 1, and a lower end surface 9 of the stamping surface portion 3 whose lower end edge 8 is below the stamping plate 4.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the above construction, the rotary rubber stamp B impregnated with ink in the first and second ink stands A according to the present invention has substantially the same structure as a conventional general one. The difference is that the material of the stamp face and the stamping assisting part are provided. That is, the rotary rubber stamp b is one of the so-called penetrating stamps, and at least each stamp surface portion 3 of the rubber band stamp 2 is formed of a material having a high ink impregnating property. The portion for increasing the ink impregnating property may be the entirety of the stamp surface portion 3 or only the character portion 20 protruding from the seat portion in the stamp surface portion 3.

A specific means for making the stamped surface portion 3 large in ink impregnating property is, for example, to fill only the character portion of the mold with NBR (nitrile butadiene rubber) or other thermoplastic resin powder, Alternatively, a powder slab method in which a sheet made of polyvinyl chloride is placed and pressed and heated to form a sheet may be used. However, it is not limited to the above.

The stamping assisting portion 6 can be attached to the lower side of the frame plate 1 on both sides, and has a concave portion 7 on the side surface which comes into contact with the frame plate 1 on both sides, with which the folded piece 5 of the horizontal plate 4 for stamping can be engaged. I have. Each of the stamping assisting portions 6 of the rotary rubber stamp B used in the first ink stand A has a flat lower end edge 8, and a pair of plate-like ones is transferred to the frame plate 1 on both sides. It may be mounted so as to be in contact with each other (for example, see FIGS. 1, 4 and 5), but it may be mounted on the frame plate 1 on both sides in a rectangular cross section (for example, see FIG. 2). Here, the term "planar" means that the lower end surface is entirely flat, and may have some irregularities.

The stamping assisting portion 6 of the rotary rubber stamp B used in the second ink stand A is a pair of plate-shaped ones which are attached to the both side frame plates 1 in contact with each other. In addition, a notch 18 having a front-rear width b slightly larger than the front-rear width a of the pad 11 of the ink stand A is formed while leaving the front lower edge 16 and the rear lower edge 17 (see, for example, FIG. 3).
6 and 7). The height h of the notch 18 is determined by the inner upper edge 21 of the notch 18 when the stamp face 3 is pressed against the pad 11.
Does not contact the upper surface 13 of the pad 11.

A stamping assisting part 6 for any rotary rubber stamp A
The lower edge 8 (in the second embodiment of the present invention, the lower front edge 16 and the lower rear edge 17) is located on the lower side surface of the both side frame plate 1 and the lower side of the stamp surface portion 3 which is located below the horizontal plate 4 for stamp surface. The lower end surface (specifically, the lower end surface of the character portion 20 in the stamp surface portion 3) 9 is located at a position above the lower end surface by a small dimension s (for example, FIG. 4, FIG.
6 and 8). The slight dimension s mentioned above means that the stamp face 5
Although it depends on the hardness of the ink-impregnated rubber material used for
When using a general impregnating rubber material, for example, about 0.2
It is desirable to set it to about 0.5 mm.

The ink stand A of the present invention in which the rotary rubber stamp B is impregnated with ink has a rectangular box shape with a bottom 10 having a recess 10 having an upper opening. The rubber stamp B has a size that can be engaged with the lower portion of the rubber stamp B, and a felt-coated cloth or a sponge-like ink supply pad 11 is attached to the inner bottom portion (for example, see FIGS. 1 and 3). ).

The recess 10 of the ink stand A is large enough to engage the lower portion of the rotary rubber stamp B with the stamping assisting portion 6 for both the first and second ink stands. The width a of the pad 11 in front and rear, the rotational rubber stamp B
A pad 11 having a front-to-back width a larger than the top and bottom width of the character portion 20 of the stamp surface portion 3 located below the horizontal plate 4 for stamp surface is attached.

The width c of the pad 7 is shorter than the width of the recess 10 in the first ink stand A (for example, see FIGS. 1, 2, 10 to 13). This is because the stamping assisting portion 6 of the rotary rubber stamp B used for the above-mentioned first one has the lower end edge 8 formed in a flat shape.
When the lower edge 8 is pressed against the upper surface of the pad 11,
In order not to make contact with the pad 1, a space 12 is formed between both side ends of the pad 11 and both inner side surfaces of the recess 10 so as to be able to engage the lower part of the stamping assisting portion 6. is there.

Further, the width c of the pad 11 at the second ink stand A may be such that both side ends reach the inner surfaces of the recess 10 (for example, FIG. 3). 14, 15, and 16). This is because the stamping assisting portion 6 of the rotary rubber stamp B used for the second one has the notch portion 18 formed at the lower end edge 8 with the front and rear width a slightly larger than the front and rear width a of the pad 11. This is because the notch 18 always straddles the pad 11 and the inner upper edge 21 does not contact the upper surface of the pad 11.

In the ink stand A (see FIGS. 14 and 15) in which the lateral width c of the pad 11 is such that both ends reach the inner surfaces of the recess 10, the front and rear side walls are left as they are. However, in addition to this, both side walls are eliminated, and a dovetail-shaped concave ridge 23 is formed on one end surface on both sides of the bottom.
A dovetail-shaped ridge 22 may be formed on the other end surface so that a similar ink stand A can be connected to the side (see FIG. 16 above).

At the inner bottom of the recess 10 of each of the ink stands A, a lower edge receiving base 14 is formed so that the upper surface 14 is slightly lower than the upper surface 13 of the pad 11. The cradle portion 14 may be formed so as to protrude from the inner bottom portion of the recess 10 (see, for example, FIGS. 4 to 9), but is not limited thereto. Although not shown, the pad is engaged with the recess formed in the inner bottom so that the upper surface of the inner bottom around the pad is slightly lower than the upper surface of the pad, and the lower edge receiving pedestal portion It may be.

In the first embodiment, the cradle portion 14 is formed at least in the space 12 and at a position corresponding to the lower edge 8 of each of the stamping assisting portions 6 when engaged. . Here, at least within the above-mentioned space 12 means that a total of four places are formed at the front and rear positions in the left and right spaces 12, in other words, four places are formed near the four corners which enter the spaces 12 on both sides within the recess 10. (See, for example, FIG. 10), and a space 10 on both sides.
It may be formed in a rib shape or a strip shape in the front-rear direction (see, for example, FIG. 11), or may be formed in a rib shape along both sides of the pad 11 so as to enter the space 12 on both sides. Alternatively, it may be formed in a rib shape around the pad 11 including the space 12 (see FIG. 13).

In the second embodiment, the lower end cradle portion 14 is positioned at least near the inner surfaces of both sides of the recess 10 and at a position corresponding to the lower end edge 8 of each of the stamping assist portions 6 engaged. It is formed. Here, “at least in the space 12” means that the pad 11 extends along the front and rear sides of the pad 11.
It may be formed in a rib shape having a length similar to that of the recess 10 and close to both inner side surfaces of the recess 10 (see, for example, FIGS. 14 and 16). May be formed in a short rib shape along the front and rear sides of the pad 11 from the four corners (see, for example, FIG. 15).

Each of the lower edge receiving pedestals 14 is formed such that the upper surface 15 thereof is slightly lower than the upper surface 13 of the pad 11. Here, the dimension t, which is slightly lower, depends on the material and hardness of the rubber and the pad of the stamp face part 3, but it is usually desirable to set it to about 0.6 to 0.8 mm.

The dimension t is set so that the ink is impregnated.
The stamp face 3 of the rotary rubber stamp A is engaged into the recess 10, and the lower end face 9 of the stamp face 3 (specifically, the lower end face of the character portion 20 of the stamp face section 3 as described above) 9 is the upper face 13 of the pad 11. When the contact is made, the lower end edge 8 of each stamping assisting portion 6 has not yet contacted the upper surface 15 of the receiving base portion 14 (see, for example, FIGS. 4, 6, and 8), and further, the lower end surface 9 of the stamping surface portion 3 To the upper surface 1 of the pad 11
3 when pressed slightly against the lower end edge 8 of each stamping assisting portion 6.
Is in contact with and supported by the upper surface 15 of the cradle portion 14 (for example, see FIGS. 5, 7, and 9). Although the dimension t and the dimension s vary depending on the material and hardness of the stamp face portion 3 and the pad 11 as described above, the dimension t is about 0.6 to 0.8 mm.
The dimension s is about 0.2 to 0.5 mm, and usually s
<T.

The depth of the recess 10 of the ink stand A is such that each of the stamped portions 3 coming below the stamping plate 4 is sufficiently positioned above the pad 11 when the lower portion of the rotary rubber stamp B is engaged. Make it reachable. Further, the outer shape of the ink stand A is not limited to the above-described square box shape, and it is preferable to form overhang portions 19 at the lower front and rear portions to prevent falling. The material is preferably made of, for example, ABS, polypropylene, polystyrene, polyethylene, AS resin, or other hard synthetic resin, but may be made of metal.

The use state and operation of the ink stand A for a rotary rubber stamp with the stamping assisting portion according to the present invention are as follows.

When the lower side of the rotary rubber stamp B is engaged in the recess 10 of the ink stand A in order to impregnate the stamp face 3 with the ink, first, the lower end face 9 of the stamp face 3 is Contacts the upper surface 13 of In this case, in any case, since the lower edge 8 of each stamping assisting portion 6 is located at a position slightly higher than the lower end surface 9 of the stamp surface portion 3 as described above, the lower edge 8 is in contact with the upper surface 13 of the pad 11. (See, for example, FIGS. 4, 6, and 8 above).

Next, the lower end surface 9 of the stamp surface portion 3 was lowered by the weight of the rotary rubber stamp B or by the pressing force of the hand holding the rotary rubber stamp B, and was slightly pressed against the upper surface 13 of the pad 11. At this time, the lower end surface 9 of the stamp surface portion 3 is
1 slightly bites into the upper surface 13 of the pad 11
The ink which has been impregnated into the stamp surface 3 is impregnated.

In the above case, in the ink stand A,
Since the lower edge receiving pedestal portion 14 is formed at the inner bottom portion of the recess 10 so as to be lower than the upper surface 13 of the pad 11 by a small dimension t, when the stamp face portion 3 slightly descends as described above,
In any case, the lower end edge 8 of the stamping assisting part 6 is
4 and is supported in contact with the upper surface 15 (for example, see FIGS. 5, 7, and 9).

Therefore, when the ink is impregnated into the stamp surface portion 3 of the rotary rubber stamp B, even if the force for pressing the stamp surface portion 3 against the pad 11 is too large, and even if there is a peculiarity that may be inclined at the time of stamping, the stamp may be performed. The surface portion 3 does not descend any further, and is no longer pressed against the pad 11 more strongly.

Thus, in the ink stand, when the ink is impregnated into the stamp portion 3 having a high ink impregnating property, the stamp surface portion 3 is not pressed into the pad 11 beyond a certain dimension. 3 is not impregnated more than necessary. As a result, even when the ink is impregnated into the stamp surface portion 3 and the first stamping is performed, the ink that has been excessively impregnated into the stamp surface portion is not extruded as in the related art, and therefore, the imprint becomes unclear. It does not become dirty or smudges.

Further, as described above, the stamped surface portion 3 is
Even if the pressing force is too large, the stamped surface portion 3 does not drop below a certain dimension and cannot be pressed against the pad 11, so that the pad 11 is pushed and expanded in the horizontal direction even if it is used repeatedly, or the planar state deteriorates. Thus, a clear seal can be imprinted from this surface without uneven contact with the stamp surface portion 3.

In the first case, in the first embodiment, the lower edges 8 of the stamping assisting portions 6 on both sides in the form of a plate or a rectangular cross section are formed on both inner side surfaces of the recess 10 of the ink stand A and the pad 11.
In the second embodiment, the notch portion 18 at the lower edge 8 of each stamping assisting portion 6 straddles the pad 11 in the second embodiment. No contact with 13.

When the ink stand A according to the present invention is used to make a stamp with a rotary rubber stamp B having a stamping assisting section impregnated with ink, the lower edge 8 of the stamping assisting section 6 is slightly smaller than the lower end face 9 of the stamp face section 3. The lower edge 8 abuts and supports the document 23, etc., even if pressure is applied more than a certain amount at the time of imprinting, so that no further pressing force acts.

For this reason, the force at the time of imprinting varies,
Even if there is a habit that the stamp surface portion 5 is inclined at the time of stamping, the stamp surface portion 5
Only a constant and uniform force is applied to the entire surface, the entire imprint is uniform and there is no difference in shading. At the time of imprinting, the ink is not extruded beyond a certain amount by a single imprint. The edge 11 abuts on a document or the like in a plane or at four corners, and is stable and hard to slip. For example, a partial seal of only one character can be accurately and clearly imprinted.

Further, in the second ink stand A, the rotary rubber stamp B used in the second ink stand A has a
The width c of the pad 11 is made long to fill both insides of the recess 10. Therefore, even if the rotary rubber stamp A has the character portion 20 of the stamp face portion 3 having a different size and a slightly different width in the grade, the character portion 20 of the stamp face portion 3 has a full width or 7
The ink stand A can be used even if the horizontal width is slightly different depending on the arc-minute or the arc-minute.

Particularly, in the second ink stand A,
Although the rear side wall is intact, while eliminating both side walls,
A dovetail-shaped concave ridge 23 is formed on one end face on both sides of the bottom and a dovetail-shaped convex ridge 22 is formed on the other end face, by connecting a similar ink stand A to the side. Pad 11
Can be continuously increased without gaps (see FIG. 16). Therefore, the ink stand can be used even in the case where the number of the rubber band marks 2 of the rotary rubber stamp A is large and the width is a multiple type.

Is such that the inner upper edge 21 of the notch 17 does not come into contact with the upper surface 13 of the pad 7 when the stamp face 5 is pressed against the pad 7, and is about 2.0 mm here.

As shown in FIG. 4, FIG. 6, and FIG. 8, each of the stamping assisting portions 6 has a lower end edge 11 (a front lower end edge 16 and a rear lower end edge 16 in the second example) as shown in FIGS. Lower edge 1
7) is a character portion 20 of the stamp surface portion 5 which is located below the horizontal plate 4 for stamp surface.
Is positioned above the lower end surface 9 by a small dimension s. Here, the small dimension s is about 0.3 m because a general impregnated rubber material is used for the stamp face 5.
m.

The ink stand A according to the present invention, in which the rotary rubber stamp B is engaged, is provided with a recess 10 having an upper opening.
The recess 10 has a size capable of engaging the lower part of the rotary rubber stamp B with the stamping assisting portion 6, and the inner bottom portion is covered with a cloth here by felt. A pad 11 for supplying ink is stuck.

The recess 11 of the ink stand A is large enough to engage the lower part of the rotary rubber stamp B with the stamping assisting part 6 in both the first and second ink stands. A pad 7 having a width a larger than the top and bottom width of the stamp face 3 is attached.

In the first ink stand A, the width c of the pad 11 is shorter than the width of the recess 10, and the lower part of the stamping assisting portion 6 is involved as shown in FIGS. If possible, cavities 12 are respectively formed at least between both side ends of the pad 11 and both inner side surfaces of the recess 10. Here, the width of the recess 10 of the ink stand a is about 45.0 mm, and the width c of the pad 11 is about 36.0 mm.
There is.

Pad 1 at the second ink stand A
As shown in FIGS. 14, 15, and 16, the lateral width c of each of the two is such that both ends reach both inner side surfaces of the recess 10, which is about 44 mm in this case, and is attached to the inner bottom.

The recesses 10 of the first and second ink stands B are also provided with a lower edge receiving pedestal 14 at the inner bottom so that the upper surface 15 is slightly lower than the upper surface 13 of the pad 7. It protrudes from the bottom. In the first embodiment, the pedestal portion 14 is formed at least in the space 12 and at a position corresponding to the lower edge 8 of each of the stamping assisting portions 6 when engaged.

In this case, as shown in FIGS. 1, 2 and 10, the cradle portion 14 is provided at four places at the front and rear positions within the cavity 12, in other words, at the cavities 12 on both sides within the recess 10. A total of four locations are formed near the four corners into which it enters. However, the invention is not limited to this.
As shown in FIG. 1, a rib may be formed in the space 12 on both sides in the front-rear direction, or may be formed in a rib shape along both sides of the pad 11 so as to enter the space 12 on both sides as shown in FIG. It may be formed, or may be formed in a rib shape around the pad 11 including the inside of the space 12 as shown in FIG.

The cradle part 14 of the second embodiment is
The recesses 10 are formed at least near the inner surfaces on both sides and at positions corresponding to the lower edges 8 of the above-mentioned stamping assisting portions 6 engaged with each other. Here, as shown in FIG.
Along the rear sides, the ribs are formed in the same length as the pad 11 and near the inner surfaces of the recess 10 in a rib shape. However, the present invention is not limited to this, and it may be formed in a short rib shape from the four corners in the recess 10 along the front and rear sides of the pad 11 in a form lacking the middle part of the above as shown in FIG.

The ink stand A shown in FIG. 16 is a modified example of the ink stand shown in FIG. 14. The front and rear side walls are left as they are, the both side walls are eliminated, and one side end face on both sides of the bottom is provided. A dovetail-shaped concave ridge 23 is formed, and a dovetail-shaped convex ridge 22 is formed on the other end surface. As a result, the same ink stand A can be connected to the side, and the pad 11 is continuously elongated without a gap. Therefore, the number of the rubber band marks 2 is large, and it corresponds to a multiple rotary rubber stamp having a long width. is made of.

Each of the cradle portions 14 has an upper surface 1
5 is formed so as to be slightly lower than the upper surface 13 of the pad 11. The dimension t, which is slightly lower, is
Although it depends on the material and hardness of the stamp face 3 and the pad 11, it is about 0.7 mm here. When the above-mentioned dimension s is about 0.
Since 3 mm, s <t.

The depth of the recess 10 of the ink stand A is such that each of the stamped surface portions 3 coming below the horizontal plate 4 for the stamped surface is sufficiently positioned on the upper surface of the pad 11 when the lower portion of the rotary rubber stamp B is engaged. Make it reachable. In addition, the outer shape of the ink stand A is formed with an overhanging portion 19 at the front and rear portions of the lower portion of the square box shape to prevent the ink stand A from falling down. The material of the ink stand A is also made of ABS resin here.

Now, in order to confirm the operation of the ink stand A according to the present invention, the impregnation of the ink on the stamp face portion 3 of the rotary rubber stamp B and the imprinting by the impregnation were performed as compared with the conventional ink stand. The following results were obtained.

When a conventional commercially available stamp table is used and the stamped surface is inked once with a rotary rubber stamp of ordinary rubber material and continuously imprinted on ordinary high quality paper, the imprint is It gradually faded, and the imprints that could be discriminated were at most the fifth to sixth times.

Further, using a conventional ink stand having an ink-impregnated pad, a rotary rubber stamp having an ink-impregnating property on the stamp surface but not having a stamping assist portion is used to apply the ink once, and When the same stamping is performed, the "stiffness" of the stamp surface is weak, so that a difference in shading and excessive ink appear on the stamp, and the number of times that stamping can be repeated continuously is at most 5
0 to 60 times.

Further, when a conventional ink stand having an ink-impregnated pad is used, and the same stamping as described above is performed after one-time ink application with a rotary rubber stamp having a stamping assisting part, It was possible to repeatedly imprint a beautiful imprint in which the entire imprint was uniform and there was no difference in shading up to 1000 times in succession.

However, in this case, if the force for pressing the stamp surface with the pad is too large, or if the stamp surface is inclined due to the habit at the time of stamping, the stamp surface is strongly pressed into the upper surface of the pad. A large amount of ink was impregnated, and at the time of the first imprinting, the ink sometimes came out too much, and the imprint became unclear or smudged and stained.

On the other hand, in the ink stand A according to the present invention, when the stamp face 3 of the rotary rubber stamp B is impregnated with the ink, the stamp face 3 comes into contact with the upper surface 13 of the pad 11 slightly more. When descending, the lower end edge 8 of the stamping assisting portion 6 comes into contact with the upper surface 15 of the receiving base portion 14, and the stamping surface portion 3 is supported so as not to be pressed into the pad 11 beyond a certain dimension.

For this reason, the ink is not impregnated in the stamp face portion 3 in an unnecessarily large amount at the time of inking, and even when the first stamping is performed, the ink is not pushed out of the stamp face portion 3 more than necessary. The seal was clear and did not smudge or stain. From the beginning, it was possible to obtain a beautiful imprint in which the entire imprint was uniform and there was no difference in shading, as in the case of the rotary rubber stamp with the imprinting assisting portion, and it was possible to repeatedly imprint up to the 1000th time. .

[0072]

As is apparent from the above, the ink stand for a rotary rubber stamp with a stamping assisting portion according to the present invention is provided in the first type.
Both the second and the second have the following useful effects, unlike the conventional ink stand.

The ink stand of the present invention is an ink stand for a rotary rubber stamp provided with a stamp surface portion having a large ink impregnating property and provided with a stamping assist portion. Can be continuously stamped from the time of stamping.

That is, in the conventional rotary rubber stamp with a pad having a large ink impregnating property or a rotary rubber stamp provided with a stamping assisting portion, if the force for pressing the stamp surface with the pad is too large, the stamp surface is strongly applied to the pad surface. It was press-fitted, so that a large amount of ink was impregnated into the stamp face, and sometimes the ink was too much at the time of the first stamping, resulting in unclear shadows or bleeding.

On the other hand, in the ink stand according to the present invention, both the first and second ink stands have a lower end edge receiving base formed at the inner bottom of the recess so as to be slightly smaller than the upper surface of the pad. I have. With this, when the ink is impregnated into the stamp surface of the rotary rubber stamp, when the stamp surface comes into contact with the pad upper surface and further descends a little, the lower edge of the stamping assisting portion is positioned on the upper surface of the receiving base. Will abut.

Therefore, even if the pressing force of the stamping surface portion against the pad is too large, or if the stamping surface portion is inclined due to the habit at the time of stamping, the lower end edge of the stamping assisting portion is supported on the upper surface of the receiving base as described above. By doing so, the stamp face does not descend further and is not pressed against the pad. As a result, it is possible to prevent the stamp face from being impregnated with an unnecessarily large amount of ink, so that even when the stamp is applied for the first time, unnecessary ink is not pushed out of the stamp face and a clear imprint can be obtained. The seal can be continuously and repeatedly imprinted without being blurred or stained.

In the ink stand according to the present invention, even in the case where the stamp surface is pressed against the pad with a large force, the pad can be prevented from being deformed, and the entire imprint can be made uniform with no difference in shading. It can be made sealable over a long period of time.

That is, in the conventional ink stand having a pad having a large ink impregnating property, when the stamp surface for the rotary rubber stamp is repeatedly pressed against the upper surface of the pad with a strong force, the pad is pushed laterally and stretched. In addition, the contact with the stamp face became uneven due to the poor flat condition, and it was impossible to imprint a clear imprint.

On the other hand, in the ink stand according to the present invention, in both the first and second ink stands, the lower edge receiving base is provided at the inner bottom of the recess so as to be slightly lower than the upper surface of the pad. It is formed. With this, when the ink is impregnated into the stamp surface of the rotary rubber stamp, when the stamp surface comes into contact with the pad upper surface and further descends a little, the lower edge of the stamping assisting portion is positioned on the upper surface of the receiving base. Abut and be supported.

Therefore, even if the force for pressing the stamp face against the pad is too large, the stamp face does not descend further and is not pressed against the pad. This eliminates the need for the ink stand pad to extend in the horizontal direction even when used for a long period of time and to prevent the flatness of the pad from deteriorating. Can be continuously stamped.

In the ink stand of the present invention, the ink does not adhere to the lower edge of the stamping assisting portion of the rotary rubber stamp, thereby preventing unnecessary ink from adhering to the document and becoming dirty.

That is, in the conventional device having a structure similar to the stamping assisting portion, when the stamp surface portion is brought into contact with the pad of the ink stand, the lower edge of the stamping assisting portion also comes into contact with the pad, and the ink at the time of stamping is formed. Was often attached to documents and soiled.

On the other hand, in the first embodiment of the present invention,
The lower edge of the plate-shaped stamping assisting portion is flat, but a space is formed between both inner side surfaces of the recess and both side edges of the pad so that the lower edge of each stamping assisting portion is in a floating state. is there. The second
In such a case, a notch portion slightly larger than the front and rear width of the pad is formed at the lower end edge of each stamping assisting portion, leaving the front and rear ends, so that the pad can be straddled.

Therefore, in the rotary rubber stamp of the present invention, when the stamp surface portion contacts the pad, the lower edge of the stamping assisting portion does not contact the pad, and it is possible to prevent ink from adhering. Occasionally, ink does not adhere to documents or the like at the lower edge of the stamping assisting portion.

In the ink stand according to the second aspect of the present invention, the size of the character portion of the stamp face is different, and even if the same grade, the width is slightly different in full-width, 7-width, half-width, etc. Even if there is an ink stand, it can be handled by preparing the minimum number of types of ink stands required.

That is, in the ink stand, it is necessary that the ink does not adhere to the lower edge of the stamping assist portion when the stamp surface of the rotary rubber stamp comes into contact with the pad. If the width of the pad in the recess is increased in order to make the ink stand versatile, for example, in the case of a rotary rubber stamp having a stamping assisting part having a square cross section, the pad is in contact with the pad at the lower edge of both side plates. . For this reason, it was necessary to manufacture and maintain inventory of ink stands having different sizes of recesses and pads.

On the other hand, according to the second embodiment of the present invention, a notch portion slightly larger than the front-rear width of the pad is formed at the lower end edge of the stamping assisting portion of the rotary rubber stamp used to reduce the lateral width of the pad. It is long enough to fill the office. As a result, the pad is always straddled by the notch at the lower end edge of the stamp assisting portion, and is not in contact with the pad.

For this reason, the ink stand can have a margin in the width direction, and even if the character of the stamp portion of the rotary rubber stamp is different and the width is slightly different, and if the character portion of the stamp surface is the same class, full-width characters are used. However, the ink does not adhere to the lower edges of the stamping assisting parts on both sides even if there is a slight difference in the horizontal width between each of the seven corners and five minutes. In addition, the number of rubber band stamps increased or decreased by about one, and the rotating rubber stamps with different widths also
In some cases, the ink stands can be used, and the number of types of ink stands can be reduced, which is advantageous in terms of manufacturing cost and inventory control.

In the second ink stand of the present invention, the front and rear side walls are left as they are, both side walls are eliminated, and a dovetail-shaped concave streak is formed on one end face on both sides of the bottom, and the other end face is formed. In the case where a ridge-shaped convex portion is formed, a similar ink stand can be connected to the side, and the pad can be continuously elongated without a gap. Therefore, it is possible to cope with a multiple rotary rubber stamp having a large number of rubber band marks and a long width.
