Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stamp that can be continuously printed without requiring an ink stamp.

[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, in the above-mentioned conventional ones, it is difficult to adjust the amount of ink contained in the printed body to a constant value, and therefore, there is a problem that 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 surely preventing stickiness or 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 of the sleeve and a lower end of the sleeve that projects slightly below the printing surface of the printing body. Insulating cores are attached and annular end plates are provided at both upper and lower ends, and a large number of fins are lined up at small intervals along the outer circumference of the central part between both end plates. On both sides of the fins and end plates of the ink flow adjusting member provided with longitudinal grooves, and configured fitted between fitted into the cylindrical portion of the inner cylinder print body and the inner cylinder step portion. The vertical grooves provided on both sides of the ink flow rate adjusting member were formed such that one was a narrow vertical groove reaching the lower end fin from the upper end plate and the other was a wide vertical groove reaching the lower end plate from the upper fin.

[0005]

[Action]

 In the present invention, as in the above configuration, a vertically oriented core hole 18 is provided in the center portion, a porous induction core 19 is inserted and attached, and annular end plates 20 and 21 are provided at both upper and lower ends, and between the both end plates. A large number of fins 22 are arranged along the outer periphery of the central portion at small intervals, and narrow fins 23 extending from the upper end plate 20 to the lower end fin 20 are formed on both sides of each fin 22 and end plates 20 and 21. And an ink flow rate adjusting member 17 having a wide vertical groove 24 extending from the upper end fin 22 to the lower end plate 21 are fitted in the cylindrical portion 2 of the inner cylinder 1 and between the print body 8 and the ink reservoir 4. Since it is mounted, the ink in the ink reservoir 4 penetrates the printed body 8 through the induction core 19. Then, when the ink is consumed on the printing surface 9, the replacement air passes from the printing body 8 through the wide vertical groove 24 and through the narrow vertical groove 23 into the ink reservoir 4, and as a result, The amount of ink consumed from the ink reservoir 4 penetrates into the print body 8. When the pressure in the ink reservoir 4 becomes high or the temperature rises and the ink expands, excess ink is accumulated between the fins 22 through the narrow vertical groove 23. Therefore, it is possible to prevent excessive supply to the print body 8.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. Reference numeral 1 is an inner cylinder, and a small diameter ink reservoir 4 is continuously provided at the upper end of the cylindrical portion 2 via a step 3 and a projecting edge 5 is provided at the outer periphery of the lower end. An ink injection hole 6 is provided at the upper end of the, and a cap 7 is fitted therein. Reference numeral 8 denotes a printed body which is made of porous rubber or urethane resin and has a printing surface 9 formed on the bottom thereof. The printing body 8 is replaceably fixed to the lower end surface of the inner cylinder 1 by a cylindrical holder 10. is there. 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 is an ink flow rate adjusting 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 vertically oriented core hole 18 is provided in the center portion of the inner cylinder 1, and polyacetal, urethane is used. A porous induction core 19 made of resin, polyester or the like is inserted so that the ink in the ink reservoir can be introduced into the printing body 8. Further, annular end plates 20 and 21 are provided at both upper and lower ends, and between the upper and lower end plates 20 and 21, a large number of fins 22 are arranged in rows along the outer periphery of the central portion at a small interval, and each fin 22 is provided. Vertical grooves 23, 24 are provided on both sides of 22 and the end plates 20, 21. Thus, one vertical groove 23 is formed to have a narrow width to reach the lower end fin 22 from the upper end plate 20, and the other vertical groove 24 is formed to have a wide width to reach the lower end plate 21 from the upper end fin 22.

【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 the second aspect, it is possible to more reliably always supply an appropriate amount of ink to the printing body with a simple structure. 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 likely to get dirty. There is no
