Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stamp that can be continuously printed without the need for an ink stamp and can be used for a long period of time.

[0002]

[Prior art]

 Conventionally, there has been known a printing stamp which is provided with an ink cartridge and can be continuously printed without requiring an ink stamp.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional ones have a problem in that it is difficult to adjust the amount of ink contained in the printed body to a constant amount, and thus stickiness or blurring is likely to occur during pressing. In view of the drawbacks of the prior art, the present invention intends to provide a stamp capable of reliably preventing stickiness and blurring during pressing and enabling clear continuous marking.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the stamp according to the present invention has an inner cylinder in which a small-diameter ink reservoir is connected to the upper end of a cylindrical part through a step and a protruding edge is provided on the outer periphery of the lower end, and printing is performed on the bottom. A porous printed material that forms a surface and is fixed to the lower end surface of the inner cylinder, and the lower part is formed to have a wider diameter than the upper part, and the upper part is fitted to the outer circumference of the inner cylinder, and the upper part is The outer cylinder that connects the gripping cylinder that covers the ink reservoir and the outer circumference of the lower end of the inner cylinder can be fitted, and the upper edge of the outer cylinder can be locked to the projecting edge of the inner cylinder. A sleeve cylinder that is urged downward by a spring provided between the lower end and a lower end of the sheath cylinder so as to project slightly below the printing surface of the printing body, and a required number of vertically oriented core holes are provided in the columnar support. And an ink supply member in which a porous induction core is inserted and fitted into the cylindrical portion of the inner cylinder to connect the induction core to the print body.

[0005]

In the present invention, as described above, the ink supply member 17 in which the required number of vertically oriented core holes 19 are provided in the columnar support 18 and the porous induction cores 20 are respectively inserted is provided in the inner cylinder 1. Since the guide core 20 is connected to the print body 8 by being fitted in the tubular portion 2, the ink in the ink reservoir 4 always penetrates the print body 8 through the guide core 20 in a constant amount. Then, when the ink is consumed on the printing surface 9, the consumption of the replacement air flows out from the ink reservoir 4 and permeates the printing body 8, so that stickiness and blurring during pressing are prevented. . Further, since the upper end surface of the columnar support 17 is formed so as to project in an arc shape, when the amount of ink in the ink reservoir 4 becomes small, the ink collects on the induction core 20 in the peripheral portion, so the amount of ink remaining. There is no fear that blurring will occur even when the number is extremely low.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 denotes an inner cylinder. A circular cylinder 2 has an upper end connected to a small diameter ink reservoir 4 via a step 3 and a lower end outer periphery provided with a projecting edge 5. An ink injection hole 6 is provided at the upper end of the portion 4, and a cap 7 is fitted therein. Reference numeral 8 denotes a printed body made of porous rubber or urethane resin and having a printing surface 9 formed on the bottom thereof, which is fixed to the lower end surface of the inner cylinder 1 by a cylindrical holder 10. Reference numeral 11 denotes an outer cylinder having a lower side portion formed to have a larger diameter than the upper side portion, the upper side portion of which is fitted to the outer circumference of the inner cylinder 1, and the upper end portion of the holding cylinder 12 which covers the ink reservoir 4. It is detachably connected with a screw. Reference numeral 13 is a spring fitted in a space 14 between the lower side of the inner cylinder 1 and the lower side of the outer cylinder 6. Reference numeral 15 denotes a sheath cylinder fitted to the outer periphery of the lower end of the inner cylinder 1. An upper end edge 16 provided inside the upper end of the inner cylinder 1 can be engaged with the projecting edge 5 and is pressed downward by the spring 13 to be biased. In addition, the lower end thereof projects slightly below the printing surface 9 of the printing body. Therefore, at the time of marking, it is sufficient to push the print surface 9 against the spring 13 until the print surface 9 comes into contact with the paper surface. Reference numeral 17 denotes an ink supply member fitted in the cylindrical portion 2 of the inner cylinder 1 and mounted between the printing body 8 and the step portion 3. A plurality of vertically oriented core holes 19 are provided at the peripheral portion at equal intervals, and porous induction cores 20 made of polyacetal, urethane resin, polyester, etc. are inserted and connected, and the induction cores 20 are connected to the print body 8. Then, the ink in the ink reservoir 4 can be supplied to the printing body 8.

[0007]

【The invention's effect】

 According to the present invention, since the amount of ink contained in the print body can be adjusted so as to be always constant with the configuration according to claim 1, it is possible to prevent stickiness and blurring when pressing and to ensure Can be continuously stamped on. Further, according to the configuration of claim 2, there is no fear of blurring even when the ink remaining amount in the ink reservoir is extremely small, and a simple structure can always supply an appropriate amount of ink to the printing body. You can be more certain. Further, according to the configuration of claim 3, when the ink is insufficient, the gripping cylinder and the cap can be removed and the ink can be replenished from the ink injection hole using a dropper or the like. Therefore, the replenishment of the ink is extremely easy and the hand is soiled. There is no fear. The present invention is particularly useful when applied to a relatively large stamp.
