Description

  The present invention relates to an insertion mark that can change a printing content such as a date by replacing and mounting a replacement frame on a fixed rubber printing body.

  This type of insertion mark is fitted with a replacement frame in the form of mounting the replacement frame on the stamp body by slide attachment and removal, and in the mounting window provided in the center of the fixed rubber print body. There is a form to wear. A known example of the former type of insertion stamp is, for example, Japanese Patent Application Laid-Open No. H11-260260. In this case, a replacement frame can be attached to the stamp body by engaging the stamp body and the replacement frame in a concavo-convex manner. ing.

  The present invention is a plug of the latter type, and a similar form can be seen in Patent Document 2. Here, the basic mode of the latter type of insertion stamp will be described with reference to FIG. 2. The rubber printing body 2 fixed to the lower end of the stamp body 1 has a horizontally long mounting window 4 at the center of the board surface. The date and the like can be changed by replacing the replacement piece 20 with tweezers.

  In the illustrated example, three replacement pieces 20 indicating the year, month, and day can be mounted in one mounting window 4, and an arbitrary date can be stamped by changing these combinations. The replacement piece 20 is a rubber molded product in which a marking face portion 30 projects from a lower end face 29 of a square columnar base portion 27, and is fitted into the attachment window 4 and attached to the rubber printed body 2. It is supported by the mounting window 4 in a retaining manner by elastic force and frictional force. Compared to the former type of insertion mark, this insertion mark is advantageous in that the structure for attaching the replacement piece 20 to the rubber printed body 2 is simple and the overall shape can be reduced.

  Printing regions 21 and 22 are provided on the lower surface of the rubber printing body 2 before and after the mounting window 4. In the illustrated example, two fixed print areas 21 and 22, for example, “ABC” and “DEFG” are provided before and after the variable print area (date information: 17.5.10) by the replacement piece 20. Actually, these fixed print areas 21 and 22 will contain company names, department names, names of persons in charge, and the like. On the lower surface of the rubber print body 2, protrusions 25, 25 are provided in front of and behind the mounting window 4 so as to extend in the left-right direction. By these protrusions 25, 25, as shown in FIG. A dividing line 25a that partitions the fixed imprint areas 21a and 21b and the variable imprint area 20a by the replacement frame 20 is imprinted on the sheet.

Japanese Utility Model Publication No. 56-86155 Design Registration No. 385538

  The external dimensions of the rectangular column-shaped replacement piece 20 are matched with the opening dimensions of the mounting window 4. That is, the width dimension before and after the base portion 27 of the replacement piece 20 is set to be substantially the same as the opening dimension before and after the mounting window 4. The left and right length dimensions of the base portion 27 of the replacement piece 20 are set so that the three replacement pieces 20 can be attached.

  In the above insertion mark, when the replacement piece 20 expands and deforms as the ink is absorbed, the fixed print areas 21 and 22 of the rubber print body 2 are pressed. As a result, as shown in FIG. 5B, there is a problem in that the imprinted character by the rubber printed body 2 is deformed. In addition, as shown in FIG. 5 (b), the front and rear division lines 25a and 25a are deformed in the direction in which the opposing distance between the lines 25a and 25a is increased, which is abnormally noticeable, and the overall impression formed on the paper surface is poor. There was also a problem.

  Such a problem can be solved by setting the front-rear width dimension of the base portion 27 to be slightly smaller in advance. However, in that case, when the amount of ink stored in the ink occlusion mat 3 is reduced and the so-called ink withered state is reached, the replacement piece 20 is deflated and unintentionally dropped from the mounting window 4. Cause serious problems.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides an insertion mark that can prevent deformation of the imprint on the paper surface due to expansion deformation of the replacement frame, while preventing inadvertent dropout of the replacement frame in the ink dead state.

As shown in FIGS. 1 to 3, the insertion mark according to the present invention includes a rubber printed body 2 fixed to the lower end of the stamp body 1, and a left and right horizontally long mounting window 4 formed at the center of the surface of the rubber printed body 2. A replacement piece 20 that is fitted into the attachment window 4 so as to be replaceable from below, and an ink storage mat 3 that is provided above the rubber printing body 2 and supplies ink to the rubber printing body 2 and the replacement piece 20; Have A front side fixed printing region 21 and a rear side fixed printing region 22 are provided on the lower end marking surface 13 of the rubber printed body 2 with the mounting window 4 interposed therebetween. On the lower surface of the rubber printed body 2, protrusions 25, 25 are integrally formed on the front and rear of the opening periphery of the mounting window 4 in the left-right direction, and the fixed printing area of the rubber printing body 2 is formed by the protrusions 25, 25. Separation lines 25a and 25a that partition the imprint areas 21a and 22a by 21 and 22 and the imprint area 20a by the replacement piece 20 are imprinted on the paper surface. The mounting window 4 is a through hole in which the front and rear opening inner surfaces 32 are formed in a straight shape in the vertical direction. The replacement piece 20 includes a quadrangular columnar base portion 27 and a marking surface portion 30 protruding from a lower end surface 29 of the base portion 27. In addition, as shown in FIG. 1, the front and rear wall surfaces 28, 28 of the base portion 27 of the replacement piece 20 are formed on a vertical straight surface and a lower end portion of the straight surface , toward the lower end surface 29. Inclined surfaces 31 and 31 are formed so as to be inclined downwardly . The width dimension before and after the replacement piece 20 defined by the straight surface in the absolutely dry state that does not contain any ink is the same as the opening dimension before and after the mounting window 4 defined by the facing distance between the front and rear opening inner surfaces 32. Alternatively, it is set to be large, and the replacement piece 20 is supported by the mounting window 4 in a retaining manner by the combined elastic force and frictional force of both the rubber printing body 2 and the replacement piece 20. When the replacement frame 20 is assembled to the mounting window 4 and the replacement frame 20 absorbs ink and expands and deforms in the front-rear direction, the upper surface of the replacement frame 20 is positioned above the mounting window 4 by the front and rear straight surfaces. The front and rear opening inner surfaces 32 and 32 are pushed forward and backward, and between the front and rear opening inner surfaces 32 and 32 at the lower end of the mounting window 4 and the front and rear inclined surfaces 31 and 31. A small margin gap S is formed, and the front and rear lower ends of the replacement piece 20 and the front and rear lower ends of the rubber print body 2 are close to each other through the margin gap S. Due to the existence of this margin gap S, the expansion deformation force of the replacement piece 20 does not act directly on the front and rear lower ends of the rubber printed body 2, so that the protrusions 25 and 25 are not deformed in an expanding manner in the front-rear direction. The imprint areas 21a and 22a and the dividing lines 25a and 25a that are imprinted on the paper surface are not deformed. Further, the inclination angle θ of the inclined surface 31 with respect to the vertical straight surface of the front and rear end surfaces 28 of the base portion 27 in the absolutely dry state is set to 5 to 10 ° . The “horizontal horizontally mounted window 4 formed at the center of the board surface of the rubber printed body 2” is not intended to limit the formation position of the mounting window 4 to the middle of the board surface, but above or below the board surface. Including the concept that the mounting window 4 is formed. In short, it is only necessary that the mounting window 4 is formed at any location on the surface of the rubber printed body 2.

As shown in FIG. 1, the inclination angle θ of the inclined surface 31 with respect to the vertical form of straight surfaces of the front and rear end face 28 of the base portion 27 in the absolutely dry state, to set the 5 to 10 °. When the inclination angle θ is less than 5 °, the margin gap S becomes small, and the deformation preventing effect of the rubber printed body 2 cannot be obtained satisfactorily. This is because if the inclination angle θ exceeds 10 °, the margin gap S becomes too large, and the replacement piece 20 may accidentally drop off. However, the inclination angle θ can be changed as appropriate within the above numerical range in accordance with the size of the replacement piece 20 and the size of the stamp surface portion 30.

  According to the insertion mark of the present invention, since the inclined surfaces 31 and 31 are formed at the lower ends of the front and rear wall surfaces 28 and 28 of the base portion 27 of the replacement piece 20, the replacement piece 20 is assembled to the mounting window 4. In the state 1, the front and rear lower end portions of the replacement piece 20 are close to and opposed to the rubber print body 2 through a small margin gap S.

  As a result, even when the ink is absorbed and the replacement piece 20 expands and deforms in the front-rear direction, the expansion deformation force does not directly act on the lower end portion of the rubber print body 2, and the fixed print regions 21 and 22. Can be effectively prevented. Therefore, as shown in FIG. 5A, deformation of the imprints 21a and 22a formed on the paper surface by the fixed print areas 21 and 22 (see FIG. 5B) can be prevented.

  Even in the ink dead state, elastic stress and frictional force are acting between the upper end portion of the replacement piece 20 and the mounting window 4, so that the replacement piece 20 may be accidentally dropped from the mounting window 4. Absent.

  According to the present invention, since the protrusions 25 and 25 (see FIG. 4) are not deformed, the dividing lines 25a and 25a stamped on the paper surface can be maintained neat.

  1 to 4 show an embodiment of an insertion mark according to the present invention. In FIG. 1 to FIG. 3, the insertion mark has a porous rubber print body 2 fixed to the lower end of a square stamp body 1, and an ink storage mat 3 is assembled above the rubber print body 2 in the stamp body 1. It has been.

  The rubber printing body 2 is formed with a horizontally long mounting window 4 in a vertically penetrating manner at the center of the board surface. In the present invention, description will be made with reference to a printing posture in which the rubber printing body 2 is positioned at the lower end as shown in FIGS.

  1 and 2, a square cap 5 that also serves as a grip is detachably attached to the upper end of the stamp body 1, and a rectangular tube stand 6 is pulled downward from the lower end side of the stamp body 1. It is mounted to slide up and down to stop. When the cap 5 is removed, the ink can be supplied to the ink storage mat 3 from above through the ink dropping port 7. The stand 6 is urged downward by a spring 9 mounted between the upper end of the stand 6 and the stamp body 1.

  The rubber printed body 2 is formed of a porous rubber material having continuous pores, and is fixed to the stamp body 1 via a stopper 10 and a support frame 11. The lower end edge of the fastener 10 is the lower end edge 12 of the stamp body 1, and the stamp surface 13 at the lower end of the rubber printing body 2 projects downward from the lower end edge 12 of the stamp body 1. The support frame 11 is a plastic molded product in which a cross-shaped upper frame 15 and a square frame-shaped side frame 16 formed continuously on the four peripheral edges of the upper frame 15 are integrally formed. The upper surface of the ink storage mat 3 is received by the lower surface. The opening between the crosses of the upper frame 15 serves as the previous ink dropping port 7, and the ink can be supplied to the ink storage mat 3 through this opening.

  The ink occlusion mat 3 is a porous rubber material, and its porosity and pore diameter are larger than that of the rubber printed body 2. The ink contained in the ink occlusion body 3 moves to the rubber print body 2 as it is used.

  When not in use, the lower end of the stand protrudes below the stamp body 1 with a spring 9 as shown in FIG. 1 to prevent the stamp surface 13 of the rubber print body 2 from touching the paper surface. In use, when the lower end opening of the stand 6 is applied to the paper surface and the stamp body 1 is pushed from above, the stand 6 rises against the spring force of the spring 9, and the stamp surface 13 contacts the paper surface, as shown in FIG. Such an imprint is stamped on the paper.

  1, 2, and 4, the lower end marking surface 13 of the rubber print body 2 has a fixed print area 21 on the front side for printing, for example, “ABC” across the mounting window 4, and, for example, “DEFG”. And a fixed printing area 22 on the rear side for printing characters.

  On the lower surface of the rubber printed body 2, two parallel protrusions 25, 25 are formed so as to protrude in the left-right direction before and after the opening periphery of the mounting window 4. Due to the ridges 25 and 25, the dividing lines 25a and 25a for separating the imprint areas 21a and 22a by the fixed print areas 21 and 22 of the rubber print body 2 and the imprint area 20a by the replacement piece 20 are imprinted on the paper surface (FIG. 5). 2 and 4, reference numeral 26 denotes a rectangular frame wall that protrudes along the outer peripheral edge of the rubber printed body 2 for the purpose of printing the dividing line 26 a (see FIG. 5).

  The replacement frame 20 gives date information to the stamp, and can be changed as appropriate by combining three types of frames 20 indicating the year, month, and day. The replacement piece 20 is a porous rubber molded product having continuous pores as a whole, and includes a quadrangular columnar base portion 27 and a marking portion projecting downward from a stepped lower end surface 29 of the base portion 27. 30 and is integrally formed. In the mounted state on the mounting window 4, the height dimension of the marking surface portion 30 substantially matches the height position of the marking surface 13 of the rubber printed body 2.

  In FIG. 3, each replacement piece 20 can be inserted into the attachment window 4 so as to be embedded in the attachment window 4 so that the marking portion 30 faces downward, and the elastic force and friction of both the rubber printing body 2 and the replacement piece 20 are attached. Combined with the force, each replacement piece 20 is supported by the mounting window 4 in a retaining manner. The front-rear width dimension of the base portion 27 of the replacement frame 20 in the completely dry state containing no ink is set to be substantially the same as or slightly larger than the front-rear opening dimension of the mounting window 4. The left and right length dimensions of the base portion 27 are set to be equal to the left and right length dimensions of the mounting window 4 (1/3 in the illustrated example).

  In the lower end portions of the front and rear wall surfaces 28 and 28 of the base portion 27 of each replacement piece 20, inclined surfaces 31 and 31 that are inclined downwardly toward the lower end surface 29 are formed. As shown in FIG. 1, the inclination angle θ of the inclined surface 31 with respect to the vertical front and rear wall surfaces 29 of the base portion 27 was set to 10 °.

  As shown in FIG. 3, when three replacement pieces 20 are assembled in one mounting window 4, the lower ends of the front and rear of the base portion 27 of each replacement piece 20 pass through a very small margin gap S. The lower end portion of the inner surface 32 of the opening before and after the mounting window 4 is in close proximity to each other.

  According to this, even when the replacement piece 20 expands and deforms in the front-rear direction by absorbing ink from the ink storage mat 3, the expansion deformation force does not directly act on the lower end portion of the rubber print body 2. That is, the marking surface 13 and the ridges 25 of the rubber printed body 2 are not deformed in an expanding manner in the front-rear direction. Therefore, as shown in FIG. 5 (a), the imprinted surfaces 21a and 22a and the dividing lines 25a and 25a on the paper surface are prevented from being deformed (see FIG. Appearance appearance can be kept good.

  Since the front and rear dimensions of the replacement piece 20 in the completely dry state are set to be substantially the same as the front and rear opening dimensions of the mounting window 4, the ink has run out, and the replacement piece 20 has been somewhat deflated from the expanded state. Even in this case, the replacement pieces 20 will not be carelessly dropped due to the elastic stress and frictional force with the mounting window 4 at the upper end of each replacement piece 20.

  The insertion stamp according to the present invention can be suitably used not only for the square stamp of the illustrated example but also for a round stamp or the like. The number of replacement pieces 20 to be mounted in the mounting window 4 is not limited to three, but may be more or a single number. The printing element by the replacement frame 20 is not limited to date information.

It is a vertical side view of the principal part. It is an external appearance perspective view of an insertion mark. It is a vertical side view which shows the mounting state of the replacement | exchange piece to a rubber printing body. It is a top view of an insertion mark. FIG. 5A shows an imprint by the insertion mark of the present invention, and FIG. 5B shows an imprint by the conventional insertion mark.
