Description

  The present invention relates to a stamp using a porous stamping material capable of accurately marking a predetermined position of a member to be stamped.

In order to prevent the marking surface from being exposed and contaminating other objects when not in use, the seals as described above should be placed between the stamp body and the outer cylinder around the print section of the stamp body installed in the outer cylinder. In general, it is covered with an inner cylinder that can be moved up and down, or the printing part of the stamp body is covered with an openable / closable lid. For example, Patent Document 1 discloses a stamping operation for releasing a lock mechanism. Describes an open / closed seal with a lid in which the inner cylinder is retracted and the lid is opened so that the marking surface comes into contact with the surface to be printed.
Japanese Patent No. 3864010

However, the openable seal with a lid disclosed in Patent Document 1 does not protrude from the tip of the inner cylinder because the printing portion of the stamp body does not protrude from the tip of the inner cylinder even when the lid is opened by performing a printing operation and the inner cylinder is retracted. There is a problem in that it is difficult to accurately check the position of the marking surface, and it is difficult to accurately perform marking at a predetermined position on the surface to be printed.
Therefore, the present invention enables not only the same stamping as that of this type of stamp to be performed, but also the stamper can accurately confirm the position of the marking surface, so that a highly accurate stamping can be performed at a limited position. The purpose is to provide a seal that can be made.

The stamp of the present invention completed in order to solve the above-described problems is provided with an outer cylinder, an inner cylinder that is housed in the outer cylinder, and can be moved up and down by the resilient force of a return spring, and the inner cylinder. And a stamp body that fits into the outer cylinder, a print cartridge that is detachably attached to the stamp body, a fastener that attaches a porous print portion to the lower end of the print cartridge, and an inner cylinder at an upper position in the outer cylinder. In a stamp comprising a lock to be fixed, a protrusion that is movable inward is provided on the outer surface of the inner cylinder, and an engaging portion and a pusher that is movable inward are provided on the inner surface of the outer cylinder. The lock is provided at a position where the lower end opening of the inner cylinder is pushed up to the upper side of the fastener, and the protrusion is fitted into the engaging portion to fix the raising and lowering movement of the inner cylinder, and the pushing When the part is moved inward, It is characterized in that the fixing is released.

As described above, according to the present invention, the lower end opening is always a porous printing portion of the stamp body between the outer cylinder and the upper portion of the stamp body provided inside the outer cylinder by the elastic force of the return spring. Since the stamp has an inner cylinder that can be moved up and down located below the marking surface of the printing surface, the stamping surface is always formed by the inner cylinder that is interposed between the outer cylinder so as to cover the periphery of the printing portion of the stamp body. Is exposed to the outside and does not contaminate other objects. Ordinary stamping is a normal stamping operation in which the inner cylinder is applied to the place to be imprinted on the surface to be imprinted and the outer cylinder is pushed down like this type of conventional stamp. Can be done.
Further, a protrusion provided on the side surface of the inner cylinder is provided on the side surface of the outer cylinder at a position where the lower end opening of the inner cylinder is pushed up to a position above the marking surface of the porous printing portion of the stamp body. Since the up-and-down movement of the inner cylinder is locked by being fitted into the engaging portion, it is possible to maintain a state in which the marking surface is exposed by a simple operation and perform high-precision marking at a limited position. . In addition, when the pushing portion provided on the side surface of the outer cylinder is moved inward, the opposing protrusion also moves inward and the lock is released, so that the seal face is exposed by a simple operation. Can be released.

Below, the Example concerning the stamp of this invention is described concretely, referring FIGS.
The stamp of the present invention includes an outer cylinder 1, an inner cylinder 2, a cartridge-type stamp body 3, and a single return spring 5 that causes the inner cylinder 2 to return and slide.
The outer cylinder 1 is a bottomed cylinder whose upper end is closed and its lower end is opened, and the inner cylinder 2 is a cylinder whose upper end and lower end are both open.
The inner cylinder 2 may be a one-piece cylinder, or the lower end of the inner cylinder 2 as shown in FIGS. 2 and 3 so as to prevent the ink from being inadvertently adhered to clothes or the like when being carried. A shutter mechanism 23 that is opened and closed by the appearance of the stamp body 3 may be incorporated in the opening. When the shutter mechanism 23 is incorporated, the stamp body 3 descends and comes into contact with the shutter blades, so that the shutter blades are forcibly opened by elasticity to expose the printing surface 42 to the outside. If the printing body 3 moves backward, the shutter blades automatically return to the original state due to elasticity.

  The stamp main body 3 includes a cylindrical small-diameter portion 31 that fits into a protrusion provided on the ceiling portion of the outer cylinder 1, and a slightly larger-diameter receiving tube portion 32 connected to the lower portion of the small-diameter portion 31. A print cartridge 4 is mounted inside. The inner cylinder 2 is mounted between the ceiling of the outer cylinder 1 and the upper part of the receiving cylinder 32 via a return spring 5 so as to be movable up and down.

  The return spring 5 normally slides and retracts the inner cylinder 2 that has been slid back to the original position at the time of marking, and also locks the inner cylinder 2 that is pushed up to a position above the marking surface 42 of the porous printing portion 41 and locked. When released, the inner cylinder 2 is slid back to the original position.

  The print cartridge 4 has an ink replenishment cap 43 fitted to the upper end of a cylindrical body 44 formed on the front portion thereof with an outer collar 44a to be engaged with the stamp body 3, and is formed on the inner surface of the front portion of the cylindrical body 44. The ink occlusion body 45 is fitted and locked in the enlarged diameter recessed portion 44b, and the porous printing portion 41 brought into contact with the ink occlusion body 45 is attached to the lower end of the cylindrical body 44 with a metal fastener 46. is there. The clip 14 is a portable one formed on the top of the outer cylinder 1.

On the side surface of the inner cylinder 2, a protrusion 22 is provided at the tip of a tongue piece which is connected to the side surface and cut into the periphery other than the connecting portion to give an elastic force.
Of the side surface of the outer cylinder 1, a pressing portion 13 is provided at the tip corresponding to the protruding portion 22 at the tip of the tongue piece that has one end connected to the side surface and cut into the periphery other than the connecting portion to give elasticity. It is. The lower end portion of the cut forms an engaging portion 11 into which the protruding portion 22 is fitted, and a passover portion 12 over which the protruding portion 22 rides is provided below the engaging portion 11. Since the pushing portion 13 and the overpass portion 12 protrude inward from the inner wall surface of the outer cylinder 1, the corresponding portion of the outer wall surface of the corresponding inner cylinder 2 is retreated inward to form a groove, and the pushing portion 13 and the overpass portion 12. It is preferable to adopt a configuration that prevents buffering between the inner cylinder 2 and the outer wall surface of the inner cylinder 2.
Here, the protrusion 22, the push-in portion 13, and the engaging portion 11 can be provided not only as one set but also as a plurality of sets. In addition, the shape of the tongue piece may be a circle, an ellipse, a polygon such as a triangle or a rectangle, and the like as appropriate.

The present embodiment is configured as described above, and the operation thereof will be described in detail next.
In the case of normal stamping, the inner cylinder 2 is configured as follows by holding the outer cylinder 1 in the state shown in FIGS. 2 and 3 and pressing the lower end of the inner cylinder 2 against the marking surface. Reversing against the urging force of the return spring 5, the state shown in FIG. 4 is obtained, and the marking surface 42 at the lower end of the print cartridge 4 comes into contact with the surface to be printed and normal printing is performed. Since the periphery is covered with the inner cylinder 2, the marking position cannot be accurately determined.
For this reason, when it is necessary to accurately align the marking surface 42 with the surface to be printed, the inner cylinder 2 is pushed up so that the lower end opening 21 of the inner cylinder 2 is positioned above the marking surface 42 of the porous printing portion 41. Then, the protruding portion 22 of the inner cylinder 2 imparted with an elastic force once collides with the overpassing portion 12, but the protruding portion 22 of the inner cylinder 2 is imparted with an elastic force so that the overpassing portion 12 is bent while being bent in the inner direction. When the inner cylinder 2 is pushed up and the inner cylinder 2 is further pushed up, the protrusion 22 is fitted into the engaging portion 11 of the outer cylinder 1, and the inner cylinder 2 and the outer cylinder 1 are fixed and are brought into a locked state shown in FIG.
As described above, the marking surface 42 of the porous printing portion 41 protrudes from the lower end opening 21 of the inner cylinder 2, so that the marking position 42 and the surface to be printed can be confirmed and the marking position can be accurately positioned. It is possible to accurately mark the position.
Further, in this locked state, the print cartridge 3 that has been revealed can be easily removed, which is useful when the print cartridge 3 is replaced with a new one or when the print cartridge 3 is refilled with ink. .

  To release the locked state, when the pushing portion 13 of the outer cylinder 1 is pushed in and moved inward, the opposing protruding portion 22 also moves inward, and the engagement portion 11 and the protruding portion 22 are fitted. At the same time, the process is reversed by the elastic force of the return spring 5 to return to the original state.

In the assembly of the stamp of the present invention, the print cartridge 4 is fitted to the stamp body 3, the stamp body 3 is installed in the inner cylinder 2, and then the outer cylinder is installed with the return spring 5 installed on the upper surface of the inner cylinder 2. 1 can be easily assembled by attaching the inner cylinder 2.
Although the present embodiment has been described with a cylindrical seal, it can of course be implemented with a box-shaped stamp such as a rectangular parallelepiped or a cube.

  Although the present invention has been described with reference to the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein, It should be understood that the scope of the invention can be appropriately changed without departing from the scope and spirit of the invention that can be read from the entire specification, and that a stamp with such a change is also included in the technical scope.
