Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder member which is disposed slidably up and down within a skirt member and holds a stamp material at a lower end thereof, and a holder member which is disposed above the holder member and lowers the holder member. Regarding a stamp unit having a grip member to be moved, particularly, when supplying ink to a printing material held by a holder member, an ink pack filled with ink is arranged in a holder, and a grip member and a holder member are used. The present invention relates to a stamp unit capable of supplying ink to a stamp material by opening an ink pack and a method of supplying ink to the stamp unit.

[0002]

2. Description of the Related Art Conventionally, various types of stamp units have been proposed. When attention is paid to a method of creating a stamp used for such a stamp unit, it is basically divided into the following two types. . One type is disclosed in, for example, JP-A-7-149031,
As described in Japanese Patent No. 257001 or the like, a grip portion, a stamp portion, and a skirt member are provided, and the grip portion and the stamp portion are connected so that the stamp portion can move up and down within the skirt member. There is a stamp unit on the lower surface of a stamp unit, which is provided with a stamping material having a lower surface of an ink-impregnated body covered with a thermosensitive stencil sheet obtained by bonding a thermoplastic film and a porous support.

[0003] In such a stamp unit, when forming a stamp capable of printing characters or the like from a stamp material, the stamp unit is set in a stamp producing apparatus having a thermal head, and the heat sensitivity of the stamp material is controlled by controlling the heating of the thermal head. Perforations are made in the stencil paper according to desired characters and the like to create a seal. When printing characters and the like, with the stamp unit arranged at a desired position on the printing paper,
When the grip is pressed downward, the ink impregnated in the ink impregnated body adheres to the printing paper through the perforations formed in the heat-sensitive stencil sheet, thereby printing characters and the like.

As another type of stamp unit, for example, as described in the specification and drawings of Japanese Patent Application No. 9-249983, a handle unit, a holder unit and a skirt unit are provided. There is a stamp unit in which a holder and a handle are connected so as to be movable up and down in a skirt, and a stamp face forming member is provided on the lower surface of the holder.

In this stamp unit, the stamp face forming member has a two-layer structure having an upper layer made of a hard porous resin and a lower layer made of a soft porous resin in which a light energy absorbing material such as carbon black is dispersed. Is formed. In order to make a plate of this stamp surface forming member, first, characters and images are printed via a thermal head and a transfer ribbon while a roll-shaped transparent film is conveyed in a stamp manufacturing apparatus to create a positive original. The stamp unit is set in a stamp manufacturing apparatus with a transparent acrylic plate interposed therebetween so that the positive original and the lower layer of the stamp face forming member face each other. In this state, when the xenon tube emits light, the light is applied to the lower layer of the stamp forming member through the positive document. As a result, only the lower layer portion irradiated with light corresponding to the transparent portion of the document is melted and solidified by the heat-generating action of the light absorbing material, while the lower side of the stamp surface forming member that is not melted and solidified. The layer will remain as it is in correspondence with the characters and the like of the document. Thereby, a stamp is formed on the lower surface of the stamp face forming member. When printing a character or the like, the ink is applied to the lower surface of the stamp surface forming member from the outside, and the ink is impregnated from the non-melted solidified portion (constituting the character and the like) on the lower surface of the stamp surface forming member, and then the stamp unit is printed When the handle is pressed downward in a state where the handle is disposed at a desired position on the paper, the ink impregnated in the stamp face forming member adheres to the printing paper from the non-melted and solidified portion, thereby printing characters and the like.

[0006]

However, in the stamp unit of the former type, the ink impregnated body is previously impregnated with ink, and the printing of characters or the like is repeated so that the ink impregnated body becomes less ink. Then, if it becomes impossible to print characters etc. with the desired density,
Although the stamp unit is basically disposable, it is difficult to impregnate the ink into the ink impregnated body in a short time in order to enable replenishment of the ink into the ink impregnated body. For example, to store ink once,
It is necessary to separately form an ink storage section for storing ink in the stamp section, and it is necessary to have a structure in which ink can be supplied to the storage section from outside the stamp unit. As described above, forming the ink storing section and the ink replenishing structure in the stamp section complicates the structure of the stamp section more than necessary, and also causes a cost increase.

In the case of printing a character or the like using the latter type of stamp unit, ink is applied to the lower surface of the stamp forming member from outside, and the ink is applied from the non-melt solidified portion of the lower surface of the stamp forming member. It needs to be impregnated. With such an ink application / impregnation method, it is originally difficult to impregnate a large amount of ink at a time, and therefore, it is necessary to frequently perform the ink impregnation work on the stamp face forming member. Such work is extremely complicated, and printing of characters and the like cannot be performed efficiently.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. When supplying ink to a printing material held by a holder member, the present invention provides an ink pack having a holder filled with ink. It is possible to supply the ink to the stamp material by opening the ink pack with the grip member and the holder member, so that the ink can be easily supplied to the stamp material with one touch, and the ink supply can be performed. It is an object of the present invention to provide a stamp unit that enables replenishment of ink by a simple operation of merely replacing an ink pack when performing the method, and a method of supplying ink to the stamp unit.

[0009]

In order to achieve the above object, a stamp unit according to the present invention comprises a skirt member and a holder which is disposed slidably up and down within the skirt member and holds a stamp at a lower end. In a stamp unit having a member and a grip member disposed above the holder member and configured to move the holder member downward, ink is filled in a bag-shaped pack formed of a film material, which is disposed inside the holder member. Equipped with an ink pack
The ink pack is opened by being pressed between the lower end of the grip member and the bottom of the holder member when the grip member moves the holder member downward.

In the stamp unit, when ink is supplied to the printing material, the grip member is pressed downward with the ink pack disposed inside the holder member.
At this time, the ink pack is sandwiched between the lower end of the grip member and the bottom of the holder member. Here, the ink pack is filled in a bag-shaped pack formed from a film material, and is opened by being pressed between the lower end of the grip member and the bottom of the holder member. As a result, the ink in the ink pack flows down and is supplied to the printing material. In this manner, ink can be easily supplied to the printing material with a single touch by using an ink pack that is easy to handle.

Further, when the printing of characters and the like is repeated, the amount of ink impregnated in the printing material is reduced and the density of printed characters and the like is reduced. Can supply ink by a simple operation of merely replacing an ink pack that has run out of ink with a new ink pack.

[0012] In the stamp unit according to the present invention, a cut portion that contacts the ink pack and an ink circulation hole that faces the stamp material are formed at the bottom of the holder member. It is desirable that, when pressed through the lower end of the member, the seal is opened by cooperation of the lower end and the cut portion, and the ink flowing out of the ink pack is impregnated into the stamp material through the ink circulation holes. In this case, it is possible to easily and quickly open the ink pack through the cutting section, and it is possible to quickly impregnate the ink flowing out of the ink pack into the stamp material through the ink circulation hole. Becomes

Preferably, the cutting portion includes a cutting rib formed substantially at the center of the bottom of the holder member, and the ink circulation hole is formed around the cutting rib. In this case, the ink that has flowed out of the ink pack opened by the cutting ribs is impregnated into the stamp material through the ink circulation holes formed around the cutting ribs. At this time, since the ink circulation holes are formed around the cutting ribs, the ink from the ink pack is evenly distributed over the entire bottom of the holder member, thereby uniformly distributing the ink over the entire printing material. It becomes possible to impregnate.

Further, the holder member has a peripheral wall which is slid in the skirt member, and supports the ink pack from the inner surface of the peripheral wall in cooperation with the cutting rib and has substantially the same height as the cutting rib. Desirably, a plurality of support ribs are formed. In this case, since the cutting ribs and the support ribs formed on the bottom of the holder member have substantially the same height, the ink pack is tilted or biased in one direction before opening the holder. It is arranged in a substantially horizontal state without being arranged inside. Therefore,
When the ink pack is opened, the ink flowing out of the ink pack is not locally collected in the holder member, and the ink is uniformly distributed over the entire bottom of the holder member and is uniformly distributed over the entirety of the printing material. Impregnated.

[0015] The space formed between the peripheral wall and the cutting rib above the bottom of the holder member may constitute a reservoir for ink flowing out of the ink pack when the ink pack is opened. desirable. In this way, the space formed between the peripheral wall of the holder member and the cutting rib is used as an ink storage portion, so that even when ink flows out at once when the ink pack is opened, the ink is removed from the holder member. It is possible to prevent leakage to the outside.

According to a method of supplying ink to a stamp unit according to the present invention, there is provided a skirt member, a holder member arranged to be slidable up and down within the skirt member and holding a stamp at a lower end portion, and an upper part of the holder member. A stamp unit having a grip member arranged to move the holder member downward, wherein the ink is supplied to a bag-like pack formed of a film material inside the holder member. Is disposed, and the holder member is moved downward by the grip member to squeeze the ink pack between the lower end portion of the grip member and the cut portion formed at the bottom portion of the holder member, thereby forming the ink pack. The ink material that has been opened and that has flowed out of the ink pack is contained in the stamp material through an ink circulation hole formed in the bottom of the holder member. Characterized in that it.

According to this ink supply method, similarly to the above case, with the ink pack disposed inside the holder member, the ink pack is opened by a simple operation of merely pressing the grip member downward. The ink in the ink pack can be easily supplied and supplied to the printing material with a single touch.

The stamped surface of the stamp material 3 held at the lower end of the peripheral wall 38 via the reference numeral 0 is protected.

To manufacture the stamp unit 1,
First, in order to form a stamp by forming a plate of the stamp material 3, the stamp material 3 is provided at the lower end, and the cardboard 37 is placed above the ink pack 6 while the ink pack 6 is housed inside and regulated by the positioning protrusion 36. The placed holder member 4 is set at a predetermined plate making position in the stamp manufacturing apparatus. At this time, the holder member 4 is set at a predetermined plate making position of the stamp manufacturing apparatus based on the cam action between the inclined surface of the inclined groove 43 formed in the lower holder portion 31 and the positioning member of the positioning mechanism. Further, the size of the holder member 4 is specified by cooperation of each detection groove 44 and a groove sensor provided in the positioning mechanism.

Since the cardboard 37 is disposed above the ink pack 6 while the upward movement is regulated by the positioning projection 36, the ink pack 6 can be fixed to a certain extent in the holder member 4. Thereby, the holder member 4
There is no problem even if transportation or the like is performed in a state where the ink pack 6 is arranged in the inside. Since the cutting rib 40 and the support rib 42 have substantially the same height, the ink pack 6
Before the opening, it is arranged in a substantially horizontal state without being arranged in the holder member 4 in a state of being inclined or biased in one direction.

After the holder member 4 is set at a predetermined plate making position as described above, characters and images are printed via a thermal head and a transfer ribbon while a roll-shaped transparent film is conveyed in a stamp manufacturing apparatus, and a positive document is printed. Is also set in such a manner that a transparent acrylic plate is interposed between the positive document and the lower layer of the printing material 3 so as to face each other. In this state, when the xenon tube emits light, the light is applied to the lower layer of the printing material 3 through the positive document. As a result, only the lower layer portion irradiated with light corresponding to the transparent portion of the document is melted and solidified by the heat-generating action of the light absorbing material, while the lower layer portion of the stamp material 3 not melted and solidified is formed. Are left as they are, corresponding to the characters of the document. Thereby, a stamp is formed on the lower surface of the stamp material 3.

After the plate making of the stamp material 3 is completed, the upper skirt 13
The coil portion of the torsion spring 16 is positioned on the positioning projection 18 in advance on both end surfaces of the torsion spring 16.
The holder member 4 is inserted from below into the insertion hole 10 of the skirt member 12 having one end locked by the spring locking portion 17. At this time, the inclined protrusions 35 formed on both end surfaces of the peripheral wall 32 of the upper holder portion 30 in the holder member 4
The other end of the torsion spring 16 is slid upward in the vertical groove 19 of the skirt member 2 and the other end of the torsion spring 16 is moved to the lower end of each of the inclination protrusions 35 at the time when the inclined protrusion 35 has passed over the other end of the torsion spring 16 according to its wedge shape. Locked. In this state, the holder member 4
Are urged upward by the biasing force of the torsion spring 16 in the skirt member 2 and can slide the holder member 4 downward against the biasing force of the torsion spring 16.

After assembling the holder member 4 and the skirt member 2 as described above, the insertion portion 51 of the grip member 5 is inserted into the peripheral wall 32 of the holder member 4. This state is shown in FIG. As described above, when the grip member 5 is further pressed while the insertion portion 51 is inserted into the peripheral wall 32, the ink pack 6 in the holder member 4 is pressed between the cardboard plate 37 and the cutting rib 40. To go. At this time, the pressing force applied to the ink pack 6 is based on the action of the cardboard 37,
The ink is applied to the ink pack 6 almost uniformly. Therefore, the ink pack 6 is broken and opened at a position in contact with the cutting rib 40, whereby the ink pack 6 is opened at a substantially central position corresponding to the forming position of the cutting rib 40, and the ink pack 6 flows out of the ink pack 6. The ink can be distributed substantially uniformly around the cutting ribs 40. Further, since the cardboard 37 has an ink absorbing ability, when the grip member 5 is moved downward to open the ink pack 6 in the holder member 4 as described above, It is possible to prevent the ink from leaking out of the stamp unit 1 by absorbing the leaked ink. This state is shown in FIG.

Further, when the ink pack 6 is opened via the cutting rib 40, the ink flows out at once, and the space formed between the peripheral wall 32 and the cutting rib 40 is as shown in FIG.

The ink can be easily supplied to the stamp material 3 with one touch.

Further, it is necessary to supply ink to the printing material 3 due to the fact that the amount of ink impregnated in the printing material 3 decreases due to repeated stamp printing of text and the like, and the density of printed characters and the like decreases. In such a case, stamp printing can be restarted by replenishing ink by a simple operation of simply replacing a bag-shaped pack that has run out of ink with a new ink pack 6.

Further, since the cutting ribs 40 contacting the ink pack 6 and the ink circulation holes 41 facing the stamp material 3 are formed, the ink pack 6 can be easily and quickly opened via the cutting ribs 40. The ink flowing out of the ink pack 6 can be quickly impregnated into the stamp material 3 through the ink circulation holes 41.

The ink flowing out of the ink pack 6 is supplied to the ink circulation holes 41 formed around the cutting ribs 40.
The ink flow holes 41 are formed around the cutting ribs 40, so that the ink from the ink pack 6 is uniformly distributed over the entire bottom of the holder member 4. The ink can be uniformly impregnated over the entirety of the printing material 3.

Further, since the cutting ribs 40 and the support ribs 42 have substantially the same height, the ink pack 6 is placed in the holder member 4 in a state of being inclined or biased in one direction before the ink pack 6 is opened. It can be arranged in a substantially horizontal state without being arranged. Therefore, the ink flowing out of the ink pack 6 when the ink pack 6 is opened is not locally collected in the holder member 4 and the ink is
Are uniformly dispersed over the entire bottom of the stamp material 3 and are uniformly impregnated over the entirety of the stamp material 3.

Further, when the ink pack 6 is opened via the cutting rib 40, the ink flows out at once, and the space formed between the peripheral wall 32 and the cutting rib 40 is as shown in FIG. As shown in the drawing, the ink storage portion serves as a storage portion for the ink flowing out of the ink pack 6, so that even if the ink flows out at once when the ink pack 6 is opened, the ink is prevented from leaking out of the holder member 4 to the outside. can do.

Further, when the grip member 5 is moved downward, the pressing force applied to the ink pack 6 is substantially uniformly applied to the ink pack 6 based on the action of the cardboard board 37. The ink pack 6 is ruptured and opened at a position where the ink pack 6 comes into contact with the cutting rib 40, whereby the ink pack 6 is opened at a substantially central position corresponding to the position where the cutting rib 40 is formed. , Can be dispersed substantially uniformly around the cutting ribs 40. Further, since the cardboard 37 has an ink absorbing ability, as described above, the grip member 5
Is moved downward to open the ink pack 6 in the holder member 4, it is possible to absorb the ink flowing out of the ink pack 6 and prevent the ink from leaking out of the stamp unit 1.

Further, since the upward movement is regulated by the positioning projections 36, the cardboard 37 is arranged above the ink pack 6, so that the ink pack 6 is held in the holder member 4.
Can be fixed to some extent, whereby transportation or the like can be performed with the ink pack 6 disposed in the holder member 4.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention.
