Description

  The present invention relates to a rotary stamp. Specifically, the marking surface portion (rotary type) for transferring the marking surface pattern to the paper surface is a cartridge type so that the marking surface pattern can be transferred any number of times by simply replacing the marking surface portion, and the marking surface portion is formed. This prevents the detachment of the stamp surface rotating body.

  With the development of information communication in recent years, personal information has also leaked in various directions and has become a social problem. In recent years when the Personal Information Protection Law has been enforced, it is preferable to manage personal information so that it does not leak as much as possible. The management does not matter at the place of work or individual residence.

  For example, even if only the home is taken as an example, various direct mails, bills, letters addressed to individuals, and contents describing various personal information such as home delivery and parcels are sent. Of course, personal information such as address, phone number, name, etc. is written on them, so if you dispose of them without discarding them (leaving them in a garbage collection site, etc.), you can dispose of them by opening the garbage bags. Personal information can be easily obtained from this, which leads to leakage of personal information.

  For example, further personal information of the addressee can be estimated from a sender described in a sealed letter such as a discarded mail. This is because it is possible to identify the addressee from a sealed letter sent from a school or the like as a student and to easily estimate the age group. Other than that, it is also possible to estimate daily information on private homes from discarded bills (such as electricity and gas charges). Of course, the person who disposed of can also be identified. These all lead to leakage of personal information.

  Therefore, it is necessary to take measures to prevent such personal information from leaking as much as possible. For example, if a sealed letter is shown as an example, the sealed letter should be broken so that the sender, addressee, and telephone number of the sealed letter cannot be deciphered. If not, the printed surface of the sealed letter should be hidden to the extent that it cannot be read. . It may be painted black with a marker or the like.

  However, it is cumbersome to black out the printed surface and the pen-written surface (address and name fields). If possible, it is preferable to fill in the necessary parts at once. In such a case, it is possible to apply a stamp that is currently known. This stamp uses a porous imprinting member impregnated with foamed plastic such as polyurethane (for example, Patent Document 1).

  In this stamp, the stamping surface has a horizontally long rectangular shape, and the stamping pattern is transferred to the paper surface by stamping. The stamping surface is further configured to be rotatable, and the stamping surface is rotated while rotating the stamping surface. A pattern is also known (for example, Patent Document 2).

  Since this type of stamp is transferred while rotating the stamp surface portion, it is not limited by the transfer length, and therefore the stamp pattern can be freely transferred by a required length.

JP 2004-17578 A JP 2004-90577 A

  By the way, the rotary stamp disclosed in Patent Document 2 is a disposable type. In other words, when the impregnated printing liquid runs out, the printing surface pattern cannot be transferred, but the structure of the printing liquid cannot be replenished, so the mission of the stamp ends when the printing liquid runs out. Therefore, the entire stamp must be disposed of. However, from the viewpoint of effective use of resources, it is preferable that the seal face portion be configured to be exchangeable.

  In addition, when the marking portion is replaceable in this way, the support case that supports the marking portion is configured to be detachable from the stamp body, and the shaft support of the marking portion can be configured as follows. Conceivable.

  Although depending on the structure, when the rotation shaft of the marking surface portion is mounted on the shaft support portion provided in the support case, it can be considered that the shaft can be mounted from the lower surface side of the support case.

  However, in this case, since the shaft support portion is exposed on the lower surface side of the support case, paper dust, dust, etc. are likely to adhere to the shaft support portion. May be prevented from rotating properly. It is not preferable in terms of design to expose the shaft support.

  In that case, it is necessary to provide a shaft support part inside the support case. If it does so, a marking surface part will be mounted from the upper surface side of a support case. Moreover, in order to facilitate the mounting of the marking surface rotating shaft on the shaft support, a configuration in which the shaft mounting surface side of the shaft support is open is employed.

  However, when the shaft mounting surface side of the shaft support portion is opened in this way and the rotation shaft is inserted from the opened surface side so as to be pivotally supported, the mounting of the rotation shaft is facilitated. If an unnecessary force is applied to the marking surface during use, the rotating shaft may come off the shaft support.

  Accordingly, the present invention solves such a conventional problem, wherein the stamp surface portion is configured to be replaceable, and the stamp surface portion is prevented from coming off even when an unnecessary force is applied to the stamp surface portion. This is a proposal. Since the stamp pattern can be appropriately changed depending on the application, if the stamp pattern is appropriately selected, it can be used as a normal stamp.

In order to solve the above-mentioned problem, a rotary stamp according to the present invention described in claim 1 is composed of a stamp main body and a rotary stamping surface portion provided on the lower surface side of the stamp main body. The surface portion has a printing surface rotating body and a support case that rotatably supports the printing surface rotating body, and the printing surface rotating body has a printing surface pattern portion formed on a peripheral surface of a cylindrical printing liquid impregnated member. The support case is configured to be detachable from the stamp body, and is provided with a pair of shaft support portions for rotatably mounting the stamp surface rotating body, and the pair of shaft support portions is a pair of legs. The stamp main body is provided with a pressing plate for preventing separation from the shaft of the stamping surface rotating body inside the stamp main body, and the pressing plate has a holding piece for holding the pair of leg portions. Features .

  In the present invention, a rotary stamp is constituted by the stamp body and the rotary stamping surface portion. The stamp body functions as a gripping part. The stamp main body is hollow and is configured as a vertically long rectangular body having an open lower end.

  A rotary marking surface portion is provided on the lower surface of the stamp body. The rotary marking surface portion is composed of a marking surface rotating body and a support case that supports the marking surface rotating body. The rotary marking surface portion is composed of a cylindrical printing liquid impregnated member and a rotating shaft that holds the printing liquid impregnated member. The peripheral surface of the printing liquid impregnated member is a printing surface pattern portion.

  The stamp surface pattern is a stamp surface according to the application. As described above, when concealing the font on the printing surface such as the address, the pattern on the printing surface serving as the base is unreadable by transferring the stamp surface pattern. The stamp surface pattern is a convex surface, and other peripheral surfaces (concave surfaces) are processed so that the seal solution does not leak, so that only the stamp surface pattern is infiltrated with the seal solution.

  The support case has a window hole formed on the lower side of the center thereof, and the rotary marking surface portion is held through the window hole so that a part thereof is exposed to the outside. Therefore, a pair of shaft support portions are formed along the window hole so as to face the inner surface side of the support case. The shaft support portions are formed at both ends in the longitudinal direction of the window hole.

  In order to make it easy to mount the rotation shaft of the rotary marking surface portion, the shaft support portion is provided with a shaft mounting hole for rotatably holding the rotation shaft, and a pair of the shaft mounting surface side is connected to the shaft mounting hole. Leg is provided.

  Accordingly, a space is formed between the pair of legs. The shaft core of the rotating shaft is mounted in the shaft mounting hole using this open space.

  A holding plate is provided so that the rotating shaft does not detach from the shaft mounting hole. The holding plate is provided with a leg piece that faces the space, and the shaft core is supported by the leg piece. Therefore, even if an inadvertent external force that causes the shaft core to be detached from the shaft mounting hole is applied, the leg core prevents the shaft core from being lifted, and the rotating shaft does not leave the shaft mounting hole. When the external force disappears, the shaft core is again accommodated in the shaft mounting hole, so that stable running at all times can be realized.

  A pressing plate provided with a clamping piece that clamps the pair of legs may be used. The pressing plate is integrally formed with the stamp body in the hollow of the stamp body.

  In the present invention, since the rotary stamp face portion is configured to be detachable from the stamp body, the rotary stamp face portion can be reused simply by exchanging the rotary stamp face portion, and the rotary stamp can be used effectively. In addition, the rotary stamping surface is provided with a shaft support inside the support case and a pressing plate that prevents the stamping surface rotating body from being detached from the shaft support. It is possible to prevent the rotator from separating and to realize stable running of the stamp surface rotator.

  Next, a preferred embodiment of the rotary stamp according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an outline of a rotary stamp 10 according to the present invention. 2 is a front view thereof, and FIG. 3 is a right side view thereof. As shown in FIGS. 1 to 3, the rotary stamp 10 has a substantially long and flat cube.

  The rotary stamp 10 includes a stamp main body 10A and a rotary stamp face portion 10B provided on the lower surface side thereof.

  The stamp main body 10A is hollow and is configured as a vertically long rectangular body having a lower end opened. Since the stamp main body 10A functions as a grip portion, it is somewhat long so that it can be easily gripped. The stamp body 10A is made of plastic.

  A rotary marking surface portion 10B is provided on the lower end surface of the stamp body 10A. The rotary stamping surface portion 10B includes a stamping surface rotating body 20 and a support case 30 that supports the stamping surface rotating body 20.

  As shown in FIG. 4, the marking surface rotating body 20 includes a cylindrical printing liquid impregnated member 21 and rotating shafts 40 and 45 that hold the printing liquid impregnated member 21. The printing liquid impregnated member 21 is made of a material that can be impregnated with the printing liquid for a long period of time. In this example, a thermoplastic resin such as a porous polyurethane foam is used.

  The peripheral surface of the printing liquid impregnated member 21 is a printing surface pattern portion 22. The marking surface pattern is formed over the entire peripheral surface of the marking liquid impregnated member 21 and is a marking surface according to the application. As described above, when concealing the font on the printing surface such as the address, the printing surface pattern is transferred so that the font on the printing surface serving as the base becomes unreadable. Details will be described later.

  The printing surface pattern is a convex surface, and the blank portion (concave surface) is processed so that the printing solution does not leak, so that only the printing surface pattern is infiltrated with the printing solution. For example, it is a stamp face pattern configured in a flash manner so that pores remain only on the convex surface.

  Specifically, when a thermoplastic thermoplastic polyurethane foam material made of a porous material is used as the printing liquid impregnated member 21, a blank portion of the printing surface pattern portion is left so that only the convex surface of the printing surface pattern portion remains. By applying a heated mold to the (concave surface) or by irradiating a laser beam to melt and cure it, it can be processed so that the printing liquid does not ooze out. By this processing, the printing liquid can ooze out only on the convex surface of the printing surface pattern. In this embodiment, the stamp face pattern is formed by the uneven surface, but the stamp face pattern can also be formed on a flat face by the method described above.

  A rotating shaft made of resin is attached and fixed to the cylindrical printing liquid impregnated member 21. In this example, the rotating shaft is divided into two, and the pair of rotating shafts 40 and 45 are fixed to the printing liquid impregnating member 21 by being mounted from the respective end portions.

  One rotating shaft 40 is composed of a bottomed shaft tube 40a that is open on one side, and a shaft core 40b that protrudes by a predetermined length on the bottomed side. Further, an annular flange 42 extending in the radial direction from the bottomed portion side is formed integrally with the shaft tube 40a and the shaft core 40b.

  A plurality of slit-like grooves 40c as shown in FIG. 5 are provided on the outer peripheral surface of the shaft tube 40a, in this example, at intervals of approximately 45 °. The groove 40c is provided for facilitating the mounting on the printing liquid impregnated member 21 and stabilizing the contact with the printing liquid impregnated member 21 after the mounting.

  In the present embodiment, the slits 40c and 45c are formed in the shaft cylinders 40a and 45a to stabilize the contact with the printing liquid impregnation member 21, but the reverse configuration may be used. That is, the same effect can be expected even in a configuration in which a groove is provided in the imprinting member impregnated member 21 and a protrusion is provided on the shaft cylinders 40a and 40b, and the groove and the protrusion are fitted.

  The other rotating shaft 45 is configured in the same manner, and as shown in FIG. 4, a shaft tube 45a, a shaft core 45b and a flange 46 are integrally formed, and a groove is formed on the peripheral surface of the shaft tube 45a. 45c is provided.

  The imprinting member 21 has a thickness of 3 mm, a diameter of about 15 mm, and a length of about 15 mm. Therefore, the flanges 42 and 46 are selected to have outer diameters that contact about half of the thickness of the printing liquid impregnated member 21. The diameters of the shaft cores 40b and 45b of the rotary shafts 40 and 45 are 2.5 to 3.0 mm. These numerical values are not limited to the examples.

  Next, the support case 30 will be described with reference to FIG. The support case 30 is configured to be detachable with respect to the stamp main body 10A while pivotally supporting the above-described marking surface rotating body 20 in a rotatable manner.

  A rectangular window hole 31 is formed in the support case 30 on the lower surface side of the center, and a part of the peripheral surface (a part of the stamp face pattern portion 22) is exposed to the outside through the window hole 31. The stamp surface rotating body 20 is held on the surface.

  Therefore, a pair of shaft support portions 32 and 33 are formed along the window hole 31 so as to face the inner surface side of the support case 30. The shaft support portions 32 and 33 are formed at both ends of the window hole 31 in the longitudinal direction (longitudinal direction of the marking surface rotating body 20).

  The configuration of the shaft support portions 32 and 33 will be described with reference to FIGS. 5 and 7. One shaft support 32 is provided with a shaft mounting hole 32c having a predetermined diameter at the center thereof. The shaft mounting hole 32c is not drilled over the entire circumference, but a portion corresponding to the upper surface of the shaft support portion 32 is partially opened.

  A pair of leg portions 32 a and 32 b are provided so as to face the space portion 36 corresponding to the open portion and continue to the shaft mounting hole 32 c. The width of the space 36 is narrower than the inner diameter of the shaft mounting hole 32c.

  The degree of narrowing is arbitrary, but the rotation shaft (actually, the shaft core 40b) 40 is moved while slightly widening (bending) the pair of legs 32a and 32b via the space 36 as will be described later. Since it is press-fitted and attached, the attachment is relatively easy, and the width of the attached rotating shaft 40 is selected so as not to easily come out in the normal use state of the stamp surface rotating body 20 (see FIG. 5).

  The width varies somewhat depending on the material constituting the shaft support 32. In this example, since it is a molded product made of ABS resin, approximately 70% to 80% of the inner diameter of the shaft mounting hole 32c is selected as the width of the space portion 36.

  The other shaft support portion 33 is configured in the same manner. Therefore, as shown in FIG. 5, the space portion formed by the pair of leg portions 33a and 33b has a pair of leg portions 33a and 33b and a shaft mounting hole 33c. The width of is also selected to be the same length as described above.

  As shown in FIG. 4, the shaft support portions 32 and 33, particularly the shaft mounting holes 32 c and 33 c from the lower surface of the support case 30 are exposed so that a part of the marking surface pattern portion 22 is exposed from the window hole 31 when the marking surface rotating body 20 is mounted. The positional relationship is selected.

  In relation to the shaft support portions 32 and 33, as shown in FIG. 4, a pressing plate 50 is provided so that the shaft cores 40b and 45b of the rotary shafts 40 and 45 are not detached from the shaft mounting holes 32c and 33c.

  The pressing plate 50 that functions to prevent the rotation shaft from detaching is a plate body that is provided so as to hang from the inside of the stamp main body 10A as shown in FIGS. 8 and 9, and in this example, the pressing plate 50. On the end face side of each of the shaft support portions 32 and 33, facing each space portion (only the space portion 36 on the shaft support portion 32 side is shown), and holding a small clearance with respect to each of the mounted shaft cores 40b and 45b. The leg pieces 50a and 50b face each other (see FIGS. 4 to 6).

  The leg pieces 50a and 50b are elongate plates that can be inserted into the space 36, and their tip portions facing the shaft cores 40b and 45b are slightly curved as shown in FIGS. Even if the shaft cores 40b and 45b come into contact with each other, the contact resistance (rotational friction) is reduced.

  If a force (external force) more than expected is applied to the marking surface rotating body 20 during use of the stamp, the shaft cores 40b and 45b may be detached from the shaft mounting holes 32c and 33c, but even if such an external force is applied. Since the shaft cores 40b and 45b come into contact with the leg pieces 50a and 50b, it is possible to reliably prevent the shaft cores 40b and 45b from being detached from the shaft mounting holes 32c and 33c.

  The support case 30 is configured to be detachable from the stamp body 10A. In this example, a lock mechanism is provided on the short-side surfaces of the stamp body 10 </ b> A and the support case 30.

  This will be described with reference to FIG. The lock mechanisms 13 and 14 are configured using the upper end surfaces of the short sides 35a and 35b of the support case 30 and the lower end surfaces of the short sides 12a and 12b constituting the stamp body 10A.

  Locking recesses 13b and 14b whose thickness is almost halved are formed on the short sides 35a and 35b, and the thicknesses are similarly formed on the short sides 12a and 12b on the side of the stamp main body 10A, which is opposite thereto. The locking projections 13a and 14a formed in half are provided, and the support case 30 is locked to the stamp main body 10A by locking the locking projections 13a and 14a in the locking recesses 13b and 14b. Is done.

  By providing the lock mechanisms 13 and 14, the rotary marking surface portion 10B can be attached to and detached from the stamp main body 10A, so that the rotary marking surface portion 10B can be used as a cartridge type.

  In addition, as shown in FIGS. 5 and 6, the end surface of the support case 30 on the long side 35c, 35d side is configured to simply contact the corresponding long side 12c, 12d of the stamp body 10A. A lock mechanism as described above can also be attached to these portions. As shown in FIGS. 2 and 3, the support case 30 protects the stamp face pattern portion 22 with a cap 70.

  FIG. 10 shows an example of the stamp pattern formed on the stamp pattern portion 22. As described above, when this rotary stamp 10 is used for the purpose of transferring the stamp face pattern and hiding the addressed portion, the size and the pattern configuration match the purpose.

  An example is shown in FIG. FIG. 10 is a development view of the stamp face pattern, wherein the length Wa in the vertical direction corresponds to the circumference (circumferential length) of the stamp face rotator 20, and the length Wb in the horizontal direction is the width (length) of the stamp face rotator 20. ).

  In this example, characters, numbers, symbols, and other fonts whose sizes and thicknesses are randomly changed are arranged in a balanced manner so that the space between the fonts is reduced, and the printing density is uniform. The stamp face pattern is configured so that

  The kanji is interwoven with Gothic and Mincho. Romaji, hiragana, and numerals are also used, such as Roman numerals and Arabic numerals, and Greek letters are also used.

  By disposing a wide variety of fonts in this way, even if the thickness or size of the name of the address serving as the background changes, it is possible to easily make the background text unreadable.

  If the stamp surface rotating body 20 having such a stamp surface pattern is rotated with respect to the paper surface on which the name is recorded and the stamp surface pattern is transferred, even if the name surface area is relatively small as shown in FIG. As shown in FIG. 12, even if the address area is large, the address part can be almost certainly hidden.

  Of course, since the stamp surface pattern can be transferred by the amount of rotation of the stamp surface rotating body 20, the stamp surface pattern can be transferred according to the length of the address to be hidden. Further, when the printing liquid is reduced and the printing surface pattern is thinly transferred, only the cartridge-type rotary printing surface portion 10B is replaced with a new cartridge or removed and the printing liquid is applied to the printing liquid impregnation member 21. If the replenished one is attached, it can be reused as the rotary stamp 10.

  Other examples of the pressing plate 50 described above are shown in FIG. In the example shown in FIG. 13 and subsequent figures, the pair of leg portions constituting the shaft support portions 32 and 33 are clamped to prevent the rotation shaft from coming off.

  Therefore, press plates 60A and 60B corresponding to the shaft support portions 32 and 33 are provided as shown in FIG. The structure of one holding plate 60A is shown in FIGS.

  The pressing plate 60A is formed with a recess 62c having a width w and a depth so that the pair of leg portions 32a and 32b can be sandwiched from both sides at the tip ends 62a and 62b. By inserting between 32a and 32b, bending of a pair of leg parts 32a and 32b is prevented.

  In this way, even if an extra force that can cause the shaft core 40b constituting the rotating shaft 40 to be detached from the shaft mounting hole 32c is applied to the stamping surface rotating body 20, the pair of leg portions 32a and 32b is operated by the concave portion 62c. Therefore, the shaft core 40b is not detached from the shaft mounting hole 32c. The same applies to the other shaft core 45b.

  Since the pressing plates 50 and 60 described above may be configured to prevent the rotation shafts 40 and 45 from being detached from the shaft mounting holes 32c and 33c, the shape and the like are not limited to the above-described embodiments.

  The present invention can be applied to a rotary stamp used when it is desired to hide the contents written on the paper.
