Next, the 1st Embodiment of this invention is described in detail based on FIGS.
The inner frame 1 is a box with an open bottom, and a slit 12 for moving a fixed shaft 52 of a stamp main body 5 to be described later is drilled in the vertical direction on the short side surface. A reversing guide 11 for reversing the stamp main body 5 is provided on the side.

  The outer frame body 4 is a box body whose bottom is opened, and a fixing hole 41 into which a fixing shaft 52 of the stamp main body 5 described later is fitted is provided inside the short side surface.

  An ink pad 6 is disposed on the ceiling portion of the inner frame 1. Various methods of arranging the ink pad 6 in the inner frame body 1 are conceivable. For example, a method of holding the ink pad 6 directly between ribs provided on the ceiling portion, or a method of holding the ceiling portion and the ink pad 6 together. A method of bonding, a method of fitting an ink cartridge or the like containing the ink pad 6 to the ceiling portion, and the like are conceivable. The ink pad 6 is obtained by impregnating a porous material such as sponge and felt with ink.

The stamp main body 5 holds a printed body 51 on the surface thereof. The printing body 51 is not a so-called permeation mark made of a porous material but a printing body of a type that transfers the ink of the ink pad 6.
On the side surface of the stamp main body 5, the fixing hole 41 of the outer frame body 4 is fitted, and a fixed shaft 52 that is in sliding contact with the slit 12 of the inner frame body 1 is engaged with the reversing guide 11. A reversing shaft 53 is provided for stably rotating 5.

An absorber 31 is disposed on the upper surface side of the ink pad 6.
The ink occlusion body 3 is formed from the absorber 31. That is, the ink occlusion body 3 and the absorber 31 are formed from the absorber 31 that is originally an integral body of the same substance.
The forming method is to press-insert the front end of the ink supply tube 21 from the upper surface side or the side surface side of the absorber 31 to form the ink occlusion body 3 near the front end of the ink supply tube 21. Thereby, the ink occluding body 3 is formed in the absorber 31, and the absorber 31 that absorbs excess ink because the capillary force is weaker than that of the ink occluding body 3 is arranged on the upper surface side and the side surface side of the ink occluding body 3. Will be.
The absorbent body 31 only needs to have a capillary gap. For example, a fiber bundle resin processed body, a fiber bundle heat fusion processed body, a felt processed body, a felt needle punch processed body, and a porous synthetic resin Examples thereof include porous materials such as foams, and synthetic resin extrusions having an ink guide path in the axial direction. The material can be a synthetic fiber resin such as acrylic fiber or polyester fiber.
Here, the capillary force is a force for raising the capillary, and in the present invention, it is a force for the ink to move through the capillary gap. Therefore, since the absorber 31 has a capillary force weaker than that of the ink occlusion body 3, the ink is difficult to move to the absorber 31.
Further, a part or all of the outer surface of the absorber 31 is provided with an air circulation port 31a that opens and communicates with the atmosphere, and is configured to perform air replacement with the outside air.
Part or all of the lower surface of the ink occlusion body 3 is opened to form an ink discharge port 3a. The ink occlusion body 3 is formed so as to be disposed on the upper surface of the ink pad 6. The ink pad 6 and the ink discharge port 3a are in contact with each other. The relationship of the capillary force between the ink pad 6 and the ink occlusion body 3 is adjusted so that an appropriate amount of ink moves to the ink pad 6.
Here, the structure provided with the outer skin which consists of synthetic resin films etc. in the outer peripheral surface of the said absorber 31 may be sufficient.

The ink tank 2 is provided with an ink supply pipe 21 having an opening at the bottom surface of the bottom, and the ink supply pipe 21 penetrates the bottom. The ink is accommodated in the ink tank interior 2a.
The ink supply tube 21 may be one, or may be a plurality of two or more as in the sixth invention shown in FIGS.
First, the case of one will be described. The cross-sectional shape of the outer peripheral surface and inner peripheral surface of the ink supply tube 21 may be, for example, any of a circle, an ellipse, or a polygon such as a triangle or a quadrangle. The tip of the ink supply tube 21 may be opened downward in the vertical direction or may be opened radially outward. Examples of the tip shape of the ink supply tube 21 include an inclined cut surface, a vertical surface, a conical surface, and a convex curved surface.
Next, two or more lines will be described. The cross-sectional shape of the outer peripheral surface and the inner peripheral surface of the ink supply tube 21 may be, for example, a circle, an ellipse, or a polygon such as a triangle or a quadrangle. Further, the tip of each of the ink supply pipes 21 may be opened downward in the vertical direction or may be opened radially outward. Examples of the tip shape of each of the ink supply pipes 21 include an inclined cut surface, a vertical surface, a conical surface, and a convex curved surface.
As shown in FIG. 12, the side walls of the ink supply pipe 21 may be connected to each other. In this case, the inside of one cylindrical body is divided by a partition wall 21a extending in the vertical direction, and two ink supply pipes 21 are independently provided in parallel inside the cylindrical body.
As shown in FIG. 13, a configuration in which a small-diameter ink supply tube 21 is arranged inside a large-diameter ink supply tube 21 may be used. In this case, an annular flow passage is formed between the inner peripheral surface of the large-diameter ink supply tube 21 and the outer peripheral surface of the small-diameter ink supply tube 21, and the cross-sectional circle is formed inside the small-diameter ink supply tube 21. A shaped flow passage will be formed.

The ink tank 2 is integrally molded. As a method of integrally molding, for example, after the ink supply tube 21 is molded by injection molding, ink is accommodated and the other end is heat-sealed, or a method of molding by blow molding can be employed.
Further, an opening may be provided at the upper end of the ink tank 2, and the upper end opening 2b may be fitted with an ink tank cap 23 and sealed.
As a method of fitting with the ink tank cap 23, the ink tank cap 23 is fitted into the opening 2 b of the ink tank 2 in a sealed state. The method for fitting the ink tank 2 and the ink tank cap 23 may be screw fitting.

The reverse stamp of the present invention is attached as follows.
First, after the ink pad 6 is arranged on the ceiling portion of the inner frame body 1, the fixed shaft 52 of the stamp main body 5 is attached so as to be freely movable in the slit 12 of the inner frame body 1. Next, the absorber 31 is disposed on the upper surface of the ink pad 6. Then, the ink supply pipe 21 provided in the ink tank 2 is connected from the side surface of the absorber 31. Then, the outer frame body 4 is attached to the inner frame body 1 with the elastic body 7 interposed on the upper surface of the inner frame body 1 and at the same time, the fixing shaft 52 is fitted into the fixing hole 41 of the outer frame body 4 and assembled. It is done.
At this time, the front end of the ink supply pipe 21 is pressed and inserted into the absorber 31, the ink storage body 3 is formed in the vicinity of the front end of the ink supply pipe 21, and the front end of the ink supply pipe 21 is inserted into the ink storage body 3. To be connected. The direction in which the tip of the ink supply tube 21 is pressed and inserted into the absorber 31 may be from the upper surface side or the side surface side of the absorber 31.

  In the present embodiment, the connection means that the ink supply pipe 21 and the ink occlusion body 3 are connected. In the present embodiment, the ink supply pipe 21 and the ink occlusion body 3 are connected and connected. The pressure contact as described above can be considered. The pressure contact means pressurization contact. For example, the ink supply pipe 21 is forcibly inserted into the absorber 31. At this time, the absorber 31 and the ink supply tube 21 are pressed against each other by a frictional force between the fiber bundle of the absorber 31 and the outer peripheral surface of the ink supply tube.

  Here, as the ink of the present invention, water-based, oil-based, dye-based and pigment-based inks can be appropriately employed.

The first embodiment of the present invention has the above-described configuration, and the operation thereof will be described in detail next.
The inversion type stamp in a standby state placed so that the lower end of the inner frame 1 is in contact with the object to be printed is the state in which the elastic body 7 is most extended, and the inner frame 1 and the outer frame 4 are the most. In a separated state, the print body 51 is in an upward state and is in contact with the ink pad 6 and is supplied with ink (see FIG. 5A).
Next, the grip-like outer frame body 4 is grasped by hand and lowered. Then, the outer frame body 4 descends while compressing the elastic body 7, and at the same time, the fixed shaft 52 fitted in the fixing hole 41 also descends in the slit 12.
When the outer frame body 4 is further lowered, the stamp main body 5 comes into contact with the reversing guide 11. Then, the stamp main body 5 rotates around the fixed shaft 52 and is turned sideways. At this time, the reversing shaft 53 is engaged with the reversing guide 11 and the stamp main body 5 is stably rotated without causing rattling or the like.
Further, when the outer frame body 4 is lowered, the printing main body 5 is completely reversed 180 degrees by the action of the reversing guide 11 so that the printing body 51 faces downward, and the printing state in which the ink of the printing body 51 is transferred to the printing object. (See FIG. 5B).
Next, the pressing to the outer frame body 4 is released. If it does so, the elastic body 7 will repel, it will follow all the processes so far, it will return to a standby state, an ink pad will contact the printing body 51, and ink will be supplied again.
The above is the description of the reversal type stamping method of the present invention.

Next, an ink supply mechanism for supplying ink from the ink supply pipe 21 to the ink occlusion body 3 will be described.
Each of the ink supply pipes 21 has a function of supplying ink in the ink tank 2 to the inside of the ink storage body 3 and a function of supplying outside air into the ink tank 2. When supplying the ink in the ink tank 2 to the ink occlusion body 3, if the main body of the stamp is on the lower surface side, the ink in the ink tank 2 passes through at least one ink supply pipe 21 due to gravity to the ink occlusion body 3. Supplied. At the same time, outside air is taken into the ink tank 2 through another ink supply pipe 21. Accordingly, the ink in the ink tank 2 is impregnated in the ink occlusion body 3 and reaches the front end opening of the other ink supply pipe 21 in which the ink impregnated in the ink occlusion body 3 has taken in the outside air. Continue to supply until.
When the ink impregnated in the ink occlusion body 3 reaches the front end opening of the ink supply pipe 21 that has taken in outside air, the front end opening is closed and airtight, and the supply of outside air into the ink tank 2 is stopped. Is done. Then, the ink supply from the ink tank 2 to the ink occlusion body 3 by the ink supply pipe 21 that has been supplying the ink is also stopped.
In this manner, the outflow of ink from the ink tank 2 and the inflow of air into the ink tank 2 (that is, replacement of ink and air) are stopped, and the ink tank 2 is temporarily sealed.
In this state, when printing is performed continuously, the ink consumed by the ink pad 6 is supplied from the ink discharge port 3 a provided in the ink occlusion body 3. The ink supplied from the ink occlusion body 3 to the ink pad 6 is supplied from the ink tank 2 through the ink supply pipe 21 and can be printed until all the ink in the ink tank 2 is consumed.
Here, the ink supply pipe 21 can perform a function of supplying the ink in the ink tank 2 into the ink storage body 3 and a function of supplying the outside air into the ink tank 2 by one.

If the outside air temperature changes when the ink tank 2 is sealed, the pressure in the ink tank changes. When the outside air temperature rises from the time when the ink tank 2 is sealed, the air in the ink tank expands to increase the internal pressure, and the ink is discharged from the ink supply pipe 21. The discharged ink is not moved to the ink pad side by being absorbed by the absorber 31 provided with the air circulation port 31a and communicating with the atmosphere.
In this state, when the outside air temperature decreases, the pressure in the ink tank decreases, and the ink discharged earlier is sucked back into the ink supply pipe 21.
Conversely, when the outside air temperature drops from the time when the ink tank is sealed, the air in the ink tank contracts, the internal pressure decreases, and the ink near the supply pipe opening is sucked from the ink supply pipe 21. When the outside air temperature rises in this state, the pressure in the ink tank rises, and the ink sucked earlier is discharged from the ink supply pipe 21.
When refilling ink, first, the outer frame 4 is removed, the ink tank 2 is taken out, and replaced with a new ink tank 2.

Next, a second embodiment of the present invention will be described in detail with reference to FIG. Here, only differences from the above-described embodiment will be described.

Next, a seventh embodiment of the present invention will be described in detail with reference to FIG. Here, only differences from the above-described embodiment will be described.
As shown in FIG. 17, a replenishment ink cartridge 22 containing ink may be detachably fitted in the opening 2b. The refilling ink cartridge 22 is a bottomed cylindrical body having an opening end 22a at one end, and the opening 2b and the opening end 22a are detachably fitted. The opening 2 b is sealed by the opening end 22 a of the refill ink cartridge 22. By being sealed, it is possible to prevent the ink stored in the refill ink cartridge from leaking outside. Here, the place where the opening 2b and the opening end 22a are fitted may be the same as or different from the place to be sealed. Various fitting methods such as concave-convex fitting, press-fitting fitting, and screw fitting can be adopted.
Further, a lid or the like (not shown) is fitted to the opening end 22a until use, and the lid is removed after use and fitted to the opening 2b. At this time, the opening end 22a is fitted into the opening 2b of the ink tank 2 while maintaining the upward direction with respect to the ground so that the ink does not leak from the replenishment ink cartridge 22.

The seventh embodiment of the present invention has the above-described configuration, and the operation thereof will be described in detail next.
When the ink is used up and the refill ink cartridge 22 is replaced, the refill ink cartridge 22 is first removed from the ink tank 2. At that time, the ink tank 2 is maintained in a state of being attached to the absorber 31. Then, a new refill ink cartridge 22 is mounted on the opening 2b of the ink tank 2 from the opening end 22a side.
When the replenishment ink cartridge 22 is mounted, first, after removing the lid (not shown) from the opening end 22a, the opening end 22a is directed upward with respect to the ground so that ink does not leak from the replenishment ink cartridge 22. The ink tank 2 is fitted into the opening 2b while maintaining the state.

Next, an eighth embodiment of the present invention will be described in detail with reference to FIGS. Here, only differences from the above-described embodiment will be described.
As shown in FIGS. 18 to 20, a plate-like plug 22b may be provided at the opening end 22a. A plug 22 b is attached to the open end 22 a of the refill ink cartridge 22 until it is attached to the ink tank 2. When the replenishment ink cartridge 22 is attached to the ink tank 2, the stopper 22b is pushed into the replenishment ink cartridge by the opening pressing portion 2c provided in the ink tank opening 2b, thereby opening the plug. Also in this case, the opening 2b is sealed by the opening end 22a of the replenishing ink cartridge 22 as in the previous embodiment.
In order to prevent the ink from leaking inadvertently, the ink tank opening 2b and the opening end 22a of the replenishment ink cartridge 22 are sealed, and then moved a small distance while maintaining this sealed state. Therefore, it is desirable to open the plug 22b. The opening pressing portion 2c may use the opening end of the opening 2b as it is, or may be provided with a separate protrusion.
The plug body 22b can be selected in various ways. For example, a spherical body (FIG. 20A), a lens-shaped body (FIG. 20B), or the like can be selected. The plug 22b may be formed of a film or the like (not shown) that can be broken by the plug-opening pressing portion 2c.

The eighth embodiment of the present invention has the above configuration, and the operation thereof will be described in detail next.
In the case of the present embodiment in which the plug 22b is provided at the opening end 22a of the replenishment ink cartridge 22, the plug pushing portion 2c is opened by pushing the plug 22b into the refill ink cartridge. Therefore, in this case, since there is no possibility that the ink flows out until the plug is opened, the direction of the opening end 22a does not need to be maintained upward with respect to the ground as in the ninth embodiment. That is, it can be mounted from any direction, upward, downward, or sideways. When the plug 22b is a film or the like, the plug 22b is broken and opened by the opening pressing portion 2c.

Next, a ninth embodiment of the present invention will be described in detail with reference to FIGS. Here, only differences from the above-described embodiment will be described.
As shown in FIGS. 21 and 22, the replenishing ink cartridge 22 includes a valve device that opens and closes when the plug 22 b is pressed against the opening pressing portion 2 c and closes when the plug 22 b is released. It may be configured to be attached to the opening end 22a.
The valve device includes a cylindrical main body 22c, a lid portion 22d, a plug 22b, and a coil spring 22e. The cylindrical main body 22c is fitted with a lid portion 22d in the opening in a state where the plug body 22b is incorporated therein via a coil spring 22e. A valve seat portion that engages with a valve portion provided in the plug body 22b is provided on the peripheral surface of the ink outflow hole provided in the lid portion 22d. Normally, the valve portion and the valve are caused by the elastic force of the coil spring 22e. The seat is pressed so as to be sealed.
When the plug 22b is pressed upward by the plug opening pressing portion 2c, the plug 22b moves upward against the elastic force of the coil spring 22e, and the sealed state of the valve portion and the valve seat portion is released. The ink in the refill ink cartridge flows into the ink tank 2. Further, when the pressing by the opening pressing portion 2c is released, the valve portion and the valve seat portion are pressed against each other and sealed by the elastic force of the coil spring 22e.
The opening pressing portion 2c may be provided integrally with the ink tank 2, or may be provided separately as shown in the figure. When separate, the inner plug 2d is attached to the opening 2b of the ink tank 2, the opening pressing portion 2c is provided at the upper end of the inner plug 2d, and the opening is formed around the opening pressing portion 2c. 2b is provided. The opening 2b and the opening end 22a are detachably fitted. As in the previous embodiment, the opening 2 b is sealed by the opening end 22 a of the refill ink cartridge 22.

The ninth embodiment of the present invention has the above-described configuration, and the operation thereof will be described in detail next.
Even in the case of the valve device in which the valve opens and opens when the plug 22b is pressed by the opening pressing portion 2c, the direction of the opening end 22a is not limited. That is, it can be mounted from any direction, upward, downward, or sideways.
When the old replenishment ink cartridge 22 is removed from the ink tank 2 in order to replace it with a new replenishment ink cartridge 22, ink may leak if the ink remains in the old replenishment ink cartridge 22. However, when the valve device is used, even if the old refill ink cartridge is removed from the ink tank, the opening end 22a is closed by the action of the valve, so that ink leakage does not occur.

Here, although the seventh to ninth embodiments have been described based on the second embodiment, the third to sixth embodiments can of course be implemented. Moreover, in FIGS. 6-22, it demonstrated with the outer frame 4 removed.
As mentioned above, although this invention was demonstrated by the said embodiment, this invention is not limited to these, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
