Description

  The present invention relates to a stamp provided with a porous printed body having countless continuous pores.

  A stamp body provided with a porous printing body having innumerable continuous pores, and surrounded by a tip portion of the stamp body, the tip is always positioned ahead of the printing surface of the printing body by the elastic force of an elastic material. An elevating sleeve and a tip provided in the elevating sleeve are always in contact with each other so that the printed body is not exposed, but when the elevating sleeve is raised by a stamping operation, printing can be performed in conjunction therewith. A stamp made of a shutter member made up of a pair of shielding plates opened in a state is already known (see, for example, Patent Documents 1 and 2).

However, since the shutter member in this type of conventional stamps is shielded by abutting the ends of a pair of shielding plates, a mechanical pencil, a ballpoint pen, a pencil, a thousand sheets, etc. When storing stamps together, if a stationery such as a mechanical pencil, ballpoint pen, pencil, or a thousand sheets enters through the stamp opening of the stamp due to opening / closing operation of the drawer or vibration during carrying, it is easily inserted from the butt edge. There is a problem that the ink is released and the evaporation of the ink is promoted to easily cause a printing defect, and the stationery comes into contact with the printing surface and is soiled by the ink. In addition, there is a problem that if the pointed stationery is inserted, the stamp face will be damaged and the imprint will be lost. In addition, the pointed stationery may cause the opening / closing body or lid to be deformed or a hole may be opened. Then, there is a problem that the shielding is incomplete and the ink evaporates quickly and cannot be used for a long time.
No. 7-26127 Japanese Patent Publication No. 7-90871

  The present invention solves the above-described problems, prevents the shutter from being opened except during the stamping operation, opens the shielding plate by the stationery entering through the opening, and damages the printed body by the entering stationery. It is an object to provide a stamp that is prevented from being smeared or smeared by ink when the stationery touched or touched the stamp surface.

  The stamp of the present invention that has solved the above-mentioned problems is a stamp body provided with a porous printing body having innumerable continuous pores, and the resilience of the resilient member that is always surrounded by the front portion of the stamp body. The elevating sleeve having the tip positioned before the printing surface of the printing body, and the elevating sleeve provided in the elevating sleeve and in contact with the leading edges so as to always conceal the printing body. In a stamp consisting of a shutter member made up of a pair of shielding plates that are opened in a state that can be imprinted in conjunction with the rise of the body, the tip of one of the shielding plates of the shutter member is not less than the appropriate number of engaging protrusions and its base width And an engagement receiving edge corresponding to the engagement protrusion, the engagement protrusion of the one shielding plate described above, It is formed on the uneven edge consisting of the engagement protrusion, and the shutter member is always It is characterized in that it has to be held in the locked state uneven edges between the end as a locking set portion engaged. In addition, although the shape of the protrusion of the engaging protrusion of the shielding plate in this invention and the shape of the engagement receiving edge is not limited, only the protrusion of the engaging protrusion has an arc shape and the engagement receiving edge is linear. The above-described lifting and lowering sheath body has a detachable mounting cylinder attached to the lower end thereof, and a shutter member attached to the inside of the mounting cylinder body. Further, an auxiliary projection for preventing the shutter member made of the shielding plate locked by the locking assembly portion from being pushed into the inner surface of the mounting cylinder is provided.

  Such a stamp is the same as this type of conventional stamp that the printed surface of the printed body is concealed by the shutter at all times except during the stamping operation. However, the shutter of the present invention uses the printed surface of the printed body. The concealing shutter is a mechanism in which the engagement protrusion of one shielding plate engages with the engagement receiving edge of the other shielding plate and the engagement protrusion engages with the engagement receiving edge of the other shielding plate. Since the leading edges of both shield plates are held in a locked state as a stop assembly, sharp-pointed stationery such as mechanical pencils, ballpoint pens, and a thousand sheets penetrates from the opening of the seal and touches both shield plates. Even if it strikes a certain locking assembly, the left and right shielding plates are alternately stacked, so that the pointed stationery is not inserted from the abutting surface by being opened from the contact portion, and the marking surface is not damaged. Moreover, since the shielding plates are stacked diagonally and the piercing force of pointed stationery is distributed, the shielding plates can be prevented from being damaged accurately, and there is no deterioration in shielding performance due to deformation or damage to the shielding plates. Therefore, fluctuations in the ink evaporation rate can be suppressed, and the designed life can be maintained.

  Further, according to the second aspect of the present invention, in the case where the projecting edge of the engaging projection piece of the shielding plate has an arc shape, when the shielding plate is closed in conjunction with the stamping operation, the tips of the engaging projecting pieces of the mutual shielding plate Since the projecting edge smoothly follows the arc and smoothly intervenes in the engagement receiving edge, it is more preferable that the corner portion is caught and the shielding is not incomplete, and the shutter member is raised and lowered as in claim 3. What was attached in the inside of the attachment cylinder removably connected with the lower end of the sheath body should just replace | exchange an attachment cylinder, when a shutter member is damaged, Furthermore, the attachment cylinder as described in Claim 4 A shutter member made of a shielding plate locked by a locking assembly is provided on the inner surface of the body with an auxiliary projection that prevents the shutter member from being pushed more than necessary when it is strongly pressed from outside. It is more preferable because it locks the shutter member more firmly. There.

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
In the figure, reference numeral 1 denotes a stamp body. This stamp body 1 has a porous printing body 2 having innumerable continuous pores attached to the tip of a shaft cylinder 3 housed in an inner casing 4. Reference numeral 5 denotes an elevating sheath body surrounded by a front portion of the stamp main body (1). The elevating sheath body 5 is normally slidably inserted into the outer sheath body 7 such as a coil spring. The outer shell body 7 and the inner shell body 4 are interlocked with the lifting and lowering sheath body 5 so that the tip of the lifting and lowering sheath body 5 is positioned ahead of the printing surface of the printing body 2 by being repelled by the elastic force of the emitting member 6. To slide.

  The shaft cylinder 3 of the stamp body 1 is formed with an ink occlusion body that supplies ink to the printing body 2 and an ink replenishing port that can replenish ink from the outside when the ink in the ink occlusion body is consumed. 3a is a lid for covering the ink supply port.

  Further, a step portion 10 is formed at the front portion of the inner shell 4 to lock the inner collar portion 5a formed at the rear end of the elevating sheath body 5, and the rear portion is provided at the rear portion of the outer shell 7. A step portion 11 is formed to abut the tip edge of the formed inner cylinder 7a. Further, an annular locking portion that engages with an annular step 7b formed on the inner surface of the inner cylinder 7a of the outer casing 7 at the rear end of the narrow cylindrical section 4a formed at the rear of the inner casing 4. 12 is formed, and the inner casing 4 in which the shaft cylinder 3 of the stamp main body 1 is built is slid down with respect to the lifting / lowering sheath 5 so that the marking surface of the printing body 2 is covered. The stamped surface is reached and stamped.

  The elevating sheath body 5 is normally brought into contact with the tip so as to conceal the printing body 2 but is opened in a state where it can be stamped in conjunction with the ascent of the elevating sheath body 5 accompanying the stamping operation. A mounting cylinder 16 having a shutter member 14 composed of a pair of left and right shielding plates 15 and 15 mounted therein is connected. In the illustrated example, the mounting cylinder 16 includes an outer cylinder 17 formed in the middle with an inner collar 17a that locks the leading edge of the elevating sheath body 5, and a rear end that is fitted to the inner surface of the outer cylinder 17 to the inner end. The inner cylinder 18 is made to abut against the flange 17a and the outer collar 18a at the tip is brought into contact with the tip of the outer cylinder 17. The shielding plate 15 is attached to a pocket portion formed between the outer cylinder 17 and the inner cylinder 18. Although 15c is inserted and attached, you may enable it to attach the attachment piece 15c inside a single cylinder instead of using such a double cylinder. When the printing body 2 is replaced, it is assumed that the mounting cylinder body 16 is removed from the lifting / lowering sheath body 5, and as shown in FIG. An auxiliary protrusion in the form of a lower point that prevents the shutter member 14 made of the shielding plate 15, 15, which is locked in the locking assembly 20 by the invading object and has a V shape, from being pushed even if it is pressed more strongly. 19 is provided as necessary.

  Further, as shown in FIG. 5, the shutter member 14 has an uneven edge composed of engagement protrusions 15 a and engagement receiving edges 15 b that are different in phase so as to be alternately overlapped and shield the marking surface. The left and right pair of substantially semicircular shielding plates are used. That is, the tip of one shielding plate 15 is formed as an uneven edge composed of an appropriate number of engaging protrusions 15a and an engagement receiving edge 15b having a width equal to or larger than the base width, and the tip of the other shielding plate 15 is formed. Is formed on an uneven edge composed of the engagement protrusion 15a of the one shielding plate 15, the engagement reception edge 15b corresponding to the engagement reception edge 15b, and the engagement protrusion 15a. A mounting piece 15c is formed. The material of the shielding plate 15 is not limited as long as sufficient durability can be obtained with respect to repeated opening and closing operations. However, in the embodiment, the shielding plate 15 is made of a tough synthetic resin material such as polypropylene resin. It is supposed to be.

  In addition, when the concavo-convex edges formed by the engaging protrusions 15a and the engaging receiving edges 15b with the left and right shielding plates 15 having different phases are overlapped with each other and engaged, The locking set 20 is assembled, and the elastic force acting in the folding direction of the shielding plate 15 is received by the locking set 20 of the left and right shielding plates 15 and 15 as described above. A strong space strong against tensile force and pressing force is formed between the engagement lock and the marking surface.

  The shielding plates 15 and 15 are automatically pushed and opened against the elastic force by contacting the outer frame of the printing body 2 that is lowered during the stamping operation. Further, the engaging protrusion 15a of the shielding plate 15 has an arc shape with a protruding edge, and the engagement is smoothly performed when overlapping with the other shielding plate 15 by making such an arc shape. This is done so that no shielding failure occurs.

  Further, the outer shell 7 and the inner shell 4 are coils in which the tip is brought into contact with the inner collar portion 5a of the elevating sheath body 5 and the rear end is brought into contact with the rib 7a formed at the rear portion of the outer shell 7. The elastic member 6 is urged by a spring member 6 such as a spring so that the shaft cylinder 3 is raised and stored in the elevating sheath body 5 and the shutter member 14 is pushed by the outer frame of the printing body 2 to be released. By doing so, the shutter member 14 engages and locks the left and right shielding plates 15 and 15 with its elastic force to firmly shield the marking surface, so that other objects can enter. However, the shielding plate 15 is not inadvertently opened, and the marking surface is accurately protected and other objects do not touch the marking surface to be contaminated.

  Thus, at the time of the marking operation, if the front end edge of the mounting cylinder 16 is brought into contact with the paper surface, the outer body 7 is pressed and the printing member 3 is lowered against the urging force of the elastic member 6. 2, the base portions of the left and right shielding plates 15, 15 attached to the support member 16 are pressed by the outer frame of the printing body 2 that descends, so that the shutter member 14 is opened, and the printing body 2 is placed on the paper surface. The seal is made by contact.

  Reference numeral 25 denotes a push button for taking out the shaft cylinder 3 provided with the printing body 2, and this push button 25 is fitted into the narrow cylinder portion 4 a of the inner shell 4, and the annular locking portion at the tip is used as the inner sleeve. 4 is engaged with the inner surface step portion so as not to fall off. When the shaft cylinder 3 is taken out, first, after removing the mounting cylinder 16 from the lifting / lowering sheath body 5, if the push button 25 is pushed into the narrow cylinder portion 4a of the inner sleeve 4, the shaft cylinder 3 is pushed. The button 25 is pushed and extracted from the inner shell 4. In this way, the shaft cylinder 3 is extracted and the printing body 2 is replaced, or the lid 3a is removed and ink is supplied to the ink occlusion body from the ink supply port.

  FIGS. 6 and 7 show another example of the shutter member 14. The shutter member 14 is locked at only one place with the engagement protrusion 15a and the engagement receiving edge 15b of the shielding plate 15 as one. Assume that the assembly part 20 is assembled, reducing the possibility of pointed stationery invading with a single part where pointed stationery easily intrudes, and making the shape simple and inexpensive molds and presses Except for the effect of reducing the product cost by manufacturing with a mold, the configuration and the function and effect are the same as those of the shutter member 14 shown in the preferred embodiment, so the same reference numerals are given and the description is omitted. To do.

  What is configured in this manner is provided in the elevating sheath body 5 and normally conceals the printing body 2 but is opened in a state where it can be stamped in conjunction with the ascent of the elevating sheath body 5 accompanying the stamping operation. As the shutter member 14, the front end of one shielding plate 15 is an uneven edge composed of an appropriate number of engagement protrusions 15 a and an engagement receiving edge 15 b having a width equal to or larger than the base width, and the other shielding plate 15 The tip is formed on an uneven edge composed of an engagement receiving edge 15b and an engagement protruding piece 15a having different phases corresponding to the engaging protrusion 15a and the engagement receiving edge 15b of the one shielding plate 15 described above. Is used, and is normally held in a locked state by the locking assembly 20 in which the concavo-convex edges at the tip of the shutter member 14 are engaged with each other. It is always concealed by the shutter 14, and the surrounding area is As a matter of course, the sharpened stationery such as a mechanical pencil, a ballpoint pen, or a thousand-thru thread penetrates through the stamping opening and is a contact portion between the shielding plates 15 and 15. Even if the part 20 is struck, the left and right shielding plates 15 and 15 are alternately overlapped, so that they are not opened from the contact part, and accordingly, stationery is inserted from the abutment surface to damage the stamp surface. Thus, the printing surface is accurately protected so as not to occur.

  Moreover, since the uneven edges of the shielding plates 15 and 15 are elastically pressed against each other, the sealing performance is high, and evaporation of ink and the like can be prevented more reliably. Furthermore, the shape of the engaging projections 15a, 15a of the shielding plates 15, 15 is not particularly limited, but those having the arcs of these projecting edges are the shielding plates 15 in conjunction with the stamping operation, When 15 is closed and the locking assembly portion 20 is formed, the leading edges of the engaging protrusions 15a and 15a of the shielding plates 15 and 15 smoothly follow the arcs to the engaging receiving edges 15b and 15b. Therefore, it is particularly preferable that the corner portion is caught and the shielding is not incomplete.

  As described above, the present invention solves the problems of this type of conventional stamp, prevents the shutter from being opened except during the stamping operation, and the shielding plate is opened by the stationery that has entered from the opening. It is possible to provide a stamp that does not damage the printed body due to stationery, or that the stationery that has entered touches the stamp surface and is not soiled by ink.
