Description

stamp cartridge

The invention relates to a stamp cassette and a method for assembling a stamp cassette, as described in the preambles of claims 1, 24 and 38.

Stamp cartridges for hand stamps are already known from the prior art. Such a stamp cassette is known for example from EP 0 719 653 B1, this stamp cassette being defined by a frame with a plate and a surrounding wall, which together define a first recess on a first side of the plate and a second recess on the second side of the plate, is formed. In the second recess, an ink-permeable body is provided which is framed by the peripheral wall, and the framed surface of the ink-permeable body and an outer periphery of the peripheral wall are covered by a heat-sensitive stencil sheet. A stamp impression can be generated by the stamp cassette by providing the template sheet with a perforation corresponding to the pattern to be printed.

Furthermore, stamp cartridges are known from the prior art, which are formed by a receiving device consisting of a base plate and a frame surrounding a receiving opening, an ink-soaked body and a stamp plate and a holding frame designed as an individual part and holding the individual components of the stamp cartridge together are. When assembling the stamp cartridge, the ink-impregnated body is placed in the receiving opening of the receiving device, then the stamp plate is placed on it and consequently the separate holding frame is used to fasten all components.

It is a disadvantage of the stamp cartridges known from the prior art that when they are assembled there is direct contact by touching the ink-soaked body and thus inadvertently contaminates the assembly device or the hands of a person during manual assembly. Furthermore, it is disadvantageous that the individual components, such as the holding frame, are designed as separate components for the receiving device and for fitting the appropriate components, which are available in different dimensions, have to be procured, a large number of stamp cartridges usually being used in the area of assembly sites of different dimensions, where due to a risk of confusion and thus an increased expenditure of time during assembly.

The object of the present invention is to provide a stamp cassette and a method for assembling stamp cassettes with which the assembly effort is reduced.

The object of the invention is achieved independently by the characterizing features of claims 1 and 24. The advantages that result from this lie primarily in the fact that the sealing of the ink-impregnated body in the recording device during assembly of the stamp cassette prevents unintentional ink delivery by the body, ink being released to the stamp plate only after it has been put on or fastened and / or after the stamp plate has been marked by a marking device. Thus cleaning times during assembly are shortened and it is possible to transfer the stamp cassette as a pre-assembled composite part to the identification device or stamp plate assembly without undesired ink leakage.

An embodiment according to the features of at least one of claims 2 or 27 is advantageous since a permanent, liquid-tight sealing of the body is possible by means of a liquid-tight and deformable or flexible sealing element, this being achieved by a deformable sealing element in the manner of a film is space-saving and can be easily removed, in particular by pulling off the film.

The stamp cassette according to the features of at least one of claims 3 to 5 and 29, 30 is advantageous because a releasable connection of the sealing element to the

Receiving device this can be removed during or after assembly of the stamp cartridge, wherein unintentional ink delivery is prevented by the liquid-tight connection in the connection area during or before assembly of the stamp cartridge and a cohesive connection in the connection area mentioned can be produced in a simple manner, in particular, if the sealing element and / or the receiving device are formed from a plastic material that is suitable for plastic welding in the connection area and has a low melting point for this purpose. Due to the design described in claim 6, the sealing element is formed as a separating element or wall, so that the stamp cassette is already opposite in the final assembled state and the sealing element automatically comes into contact by removing the sealing element.

The embodiment variant according to at least one of claims 7, 8 and 31 is advantageous since the sealing element on the engagement element can be gripped in a simple manner even when the stamp cartridge is installed and can be removed from the stamp cartridge preferably without residue by exerting a tensile force on the attack element.

The features according to at least one of claims 9 and 28 are also advantageous, since by fastening the ink-impregnated body in the receiving device, a composite part, further comprising the sealing element, is formed, as a result of which the partially assembled stamp cassette can be handled simply and cleanly. The assembly of the stamp cassette can thus take place at different locations, for example. The

Part assembly of the composite part, in which there is contact with the ink-impregnated body, can thus be carried out separately from an assembly device for the identification or attachment of the stamp plate to the stamp cassette, as a result of which the previously complex assembly of the stamp cassette with simultaneous identification of the stamp plate can now be carried out on several Assembly stations or locations can be distributed.

Due to the characterizing features of at least one of claims 10 and 26, 30, a pre-assembly of the stamp cassette is advantageously possible as far as possible that all components, in particular the receiving device, ink-soaked body and stamp plate, are connected to one another, the stamp cassette additionally being the sealing element for preventing a Includes ink transfer from the ink-soaked body to a support surface of the stamp plate. A stamp cassette in such a state can be mounted at a first station, and the stamp plate can be identified or individualized at another location. With the individualization, all that is required for the final assembly of the stamp cartridge is the removal of the sealing element. Due to the features of claims 10 and 26, pre-assembly of the stamp cassette with the stamp plate is advantageously possible. The features according to at least one of claims 11, 12, 17 and 32 are also advantageous, since a fastening means, in particular a holding element, connected to the receiving device shortens the assembly times for the assembly of the stamp cassette due to the fact that there is no downtime or set-up time to obtain a separate holding element can be. Due to a frame-shaped design with a rectangular opening, forms of stamp plates known from the prior art can be fastened to their edge strips in a simple manner by low-tensioning them.

Further advantageous features are described in at least one of claims 13 to 15 and 33, wherein the adjusting device enables a flap-like pivoting of the holding element and with structurally simple means, such as e.g. a film hinge arrangement, the adjustment of the holding element in a release or closed position is possible and the assembly effort of the stamp cassette can be kept low by the one-piece construction of the holding frame and receiving device.

The features of at least one of claims 16 and 34 relate to a further advantageous embodiment variant in which the fastening element can position the holding element in a closed position and the further components of the stamp cartridge, in particular the stamp plate and / or the ink-impregnated body, against unintentional loosening are securely arranged in the stamp cassette.

A further advantageous embodiment variant is described in at least one of claims 18 to 20, wherein by means of a stiffening element arranged in the stamp plate or in the receiving opening of the receiving device, the forces occurring during the compression of the stamp plate during the marking process can be compensated for, so that a pushing in or Moving the stamp plate in the direction of the base plate of the receiving device is prevented or counteracted.

A further advantageous embodiment relates to claim 21, since the compression of the stamp plate can be counteracted by a material with a high degree of inherent rigidity, for example by a high modulus of elasticity or density, etc., and when the stamp cassette is marked with a stamp plate attached to it, the stamp surface is shifted into the receiving opening is prevented. In claims 22 and 23 and a further advantageous embodiment is described, with which the pressure occurring when the stamp plate is marked in the stamp cassette is advantageously absorbed by the counter-holder or the rigid insertion element, which is formed as a sliding plate, whereby this Insert element can be removed from the stamp cassette after the stamp plate has been identified. The insertion element can thus also be designed as a sealing element, which enables inexpensive production.

A procedure according to the features of claim 25 is advantageous since the removal of the sealing element can be done variably and thus different assembly processes of the stamp cartridge are made possible.

Claim 35 describes an advantageous procedure in which, by supplying the stamp plate that has already been processed, it is no longer necessary to process it in the fully assembled state of the stamp cassette, and thus on submissions for balancing forces, e.g. Stiffening elements, etc., can be dispensed with and a simple construction of the stamp cassette is possible. In addition, previously used labeling devices can be used for the individualization of stamp plates.

The procedure according to claim 36 is advantageous since the assembly of the stamp cassette can be carried out completely except for the removal of the sealing element and the assembly costs can be kept low at a processing station for marking the stamp plate or can be completely omitted except for the removal of the sealing element. This is particularly advantageous if the stamp cartridge has to be moved to a location for individualization, as is the case in most cases, since no means or components for mounting the stamp cartridge have to be present at the further location ,

The procedure according to claim 37 is advantageous because the above-mentioned compression or the displacement of the stamp plate in FIG

Direction of the base plate of the receiving device can be prevented.

Another independent solution according to the invention is provided by the characterizing Features of claim 38 described. Such an assembly system is advantageous when marking the stamp plate, in the event that it is already assigned to the stamp cassette during processing by the marking device. The pressure forces occurring during processing can be compensated for or absorbed by the force compensation device and this prevents a permanent displacement of the stamp plate, in particular its pressure surface, into the receiving opening of the receiving device. Processing of a stamp plate mounted on the stamp cassette is thus only possible. Claim 39 specifies further advantageous design variants of the mounting system, the advantages of which can be found in the above-mentioned or following description.

The invention is explained in more detail below with reference to the exemplary embodiments shown schematically in the drawings.

In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally, etc. refer to the figure described and illustrated immediately and are to be transferred analogously to the new position in the event of a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

1 shows an example of a hand stamp 1 with linear actuation and rectilinear adjustment of a stamp cassette 2 when actuated. The hand stamp 1 has a handle 3 and an adjusting device 4 for a linear adjustment, the handle piece 3 via the adjusting device 4 with the stamp cassette 2 is coupled in motion, and thus is linearly adjusted according to an arrow 5 when the sliding handle 3 is actuated. As shown, the stamp cassette 2 can be adjusted, for example, via a bolt 7 which is adjustable relative to a receiving housing 6 and which has a cassette holder 8 to which the stamp cassette 2 is fastened via one or more holding elements 9. A sealing cap on the underside of the hand stamp 1 for covering the stamp cassette 2 is shown in dashed lines. It should be noted that it is also possible to use the stamp cassette 2 according to the invention with further stamp types known from the prior art, for example self-inking stamps with a 180 ° turning mechanism for the stamp plate when actuated.

In order to generate a stamp impression with such hand stamps 1 on a medium 10 by applying ink, it is necessary for the stamp cartridge 2 to comprise an ink-soaked body 11 and a stamp plate 12. The body 11 and the stamp plate 12 are held in the assembled state by a recording device 13 which is formed at least by a base plate 14 and a frame 15 which delimit a receiving opening 16 of the receiving device 13. The ink-impregnated body 11 is preferably arranged in the receiving opening 16 in such a way that a base area 17 of the body 11 lies against a boundary surface 18 of the base plate 14 and a non-captive surface 19 of the body 11 essentially parallel to a contour surface 20 delimiting the receiving opening 16 in the receiving opening 16 extends.

In the fully assembled state of the stamp cassette 2, a contact surface 21 of the body 11 opposite the base surface 17 is in contact with a support surface 22 of the stamp plate 12, the contact surface 21 being an extent 23 from the boundary surface 18 of the

Base plate 14 of the receiving device 13 is distanced and an extent 24 by which the frame 15 extends substantially perpendicular to the base plate 14 is greater than the extent 23. The stamp plate 12 can thus be arranged offset in the receiving opening 16 over a height 25, wherein in the exemplary embodiment shown, end faces 26 of the stamp plate 12, which are in contact with the contour surfaces 20 of the frame 15, seal the stamp cassette 2 against unwanted ink leakage ,

So that at a drain area 27 suitable for ink delivery with a stamp surface 28 when contacting a surface 29 of the medium 10, an ink impression can be produced on the surface 29, an ink occurrence on the printing surface 28 corresponding to the pattern to be printed is necessary. This is achieved in such a way that the stamp plate 12 is used by a material with pores that are at least partially permeable over the thickness 30 of the stamp plate 12, whereby the ink stored in the ink-impregnated body 11 at least partially penetrates the thickness of the stamp plate 12 and supplies the printing surface 28 with ink , Such porous materials, preferably made of thermoplastic, are known from the prior art, a processing process of the printing area 27 of the stamp plate 12 for individual identification, in order to enable the generation of individual stamp impressions, at a later point in the course of FIG 6 is described in more detail.

2 to 4, an embodiment variant of the stamp cartridge 2 according to the invention is shown, which, in addition to the inhalation device 13 and the ink-soaked body 11, has a sealing element 31 which is used for the liquid-tight closure or for

Covering the body 11 is formed in the receiving opening 16. The sealing element 31 is arranged in the holding device 13 in such a way that the contact surface 21 of the body 11 exposed through the holding opening 16 at its open area cannot be touched when the holding opening 16 engages from the outside, for example through the frame 15 or Base plate 14 and the sealing element 31 is completely enclosed. The sealing element 31 preferably lies directly with a cover surface 32 at least on the contact surface 21 of the body 11.

In order to achieve a complete sealing of the receiving opening 16 by the sealing element 31, a connection area 34 can be formed between the frame 15 of the receiving device 13 and a sealing surface 33 of the sealing element 31, in which the sealing element 31 and the receiving device 13 are connected in a liquid-tight manner. The attachment in this connection area 34 can be detached for a temporary purpose and therefore, if necessary, and can be bonded, for example, by means of connection methods known from the prior art, in particular materially,

Connect by diffusion, etc., which connection can be easily separated when force is applied. The sealing element 31 can be formed by a film 35, which is formed by a liquid-impermeable material and, in the exemplary embodiment shown, by a deformable material, wherein materials suitable for the film 35 are suitably deformable and / or elastic plastics, light metal alloys etc. It is also possible that the sealing element 31 is made of an absorbent material

Recording or storage of ink is formed.

For a liquid-tight sealing of the ink-impregnated body 11, there is also the possibility that the cover surface 32 of the sealing element 31 is brought into contact with the surface of the ink-impregnated body 11, after which the

Surface, e.g. of the contact surface 21, and the cover surface 32, adhesion occurs due to the diffusion effect of the ink in the body 11, and due to this adhesion effect, the sealing element 31 is adequately fastened to the body 11, so that a connection of the sealing element 31 to the receiving device 13 is not necessary , To ensure adequate sealing of the edges of the body 11 in the area of

To ensure circumferential surfaces 19 in the state inserted into the receiving opening 16, an extension of the sealing element 31, starting from the contact surface 21 along the circumferential surface 19 of the body 11 in the direction of the base plate 14, is advantageous.

When mounting the stamp cartridge 2, the receiving opening 16 is soaked in ink

Body 11 and the sealing element 31 supplied and, if necessary, fastened in the receiving opening 16. It is possible that the body 11 and the sealing element 31 are supplied separately, i.e. in a first step, the body 11 is arranged and fastened in the receiving opening 16 and then the sealing element 31 for the liquid-tight closure of the receiving opening 16 is fed to the latter, or the ink-impregnated body 11 and the sealing element 31 outside the receiving opening 16 of the receiving device 13 come into contact brought, whereby - as described above - adhesion occurs between the contact surface 21 and the cover surface 32, whereupon the composite part formed is fed to the receiving opening 16.

The body 11 preferably lies with its base surface 17 and / or peripheral surfaces 19 on the boundary surface 18 and / or the contour surface 20 of the receiving opening 16 and, after its arrangement in the receiving opening 16, is preferably used to fix its position attached to the boundary surface 18 of the base plate 14 and / or to the contour surfaces 20 of the frame 15, the attachment being carried out, for example, by adhesive bonding using an adhesive layer 36.

The receiving device 13, the body 11 and the sealing element 31 thus form a composite part 37, which cannot emit any ink during further assembly or processing, in particular the attachment or processing of the stamp plate 12. Furthermore, the composite part 37 can be transported and handled in a simple manner between different stations or locations during the assembly of the stamp cassette 2, so that the pre-assembled composite part 37 can be used in a device for identifying the stamp plate 12 and there after the marking process Stamp plate 12 assembly times shortened and contacts with ink leading to downtimes can be avoided. In summary, a shortening of the assembly or cycle times in the manufacture of stamp cartridges can be achieved by partial assembly of the stamp cartridge to the composite part 37.

An advantageous sequence of an assembly process can be carried out in such a way that first the sealing element 31 is removed or pulled off the composite part 37, and then the stamp plate 12, which has already been processed by a marking device, is placed on the ink-soaked body 11 in the receiving opening 16 and then the fastening the stamp plate 12 on the receiving device 13. The removal or removal process for removing the sealing element 31 is indicated in dashed lines in FIG. 3.

In a further possible variant of an assembly method according to FIGS. 4 to 7, after the manufacture of the composite part 37, the stamp plate 12 is supplied and optionally attached to the halide device 13, the contact surface 22 of the stamp plate 12, for example, on a cover surface 38 of the sealing element 31 Plant is brought. The sealing element 31 can then be removed.

A process sequence according to FIGS. 5 to 7 or a design of the stamp cassette according to FIG. 4 is necessary if the stamp plate 12 is attached to the receiving device 13 even before the stamp plate 12 has been processed for identification. whereby an ink flow to the stamp plate 12 is prevented by the sealing element 31 before the stamp plate drawing.

For example, the stamp plate 12 can be fastened using a fastening means 39. In the stamp cassette 2 shown in FIG. 4, the fastening means 39 is formed by an integral adhesive layer 40 which is arranged between the end faces 26 of the stamp plate 12 and the contour surface 20 of the frame 15.

In order to enable removal of the sealing element 31, for example by pulling it out of the receiving opening 16 even after the stamp plate 12 has been fastened, for example only a partial fastening of the stamp plate 12 can take place, in which at least one of the wide or long sides of the frame 15 on which the Pulling out the sealing element 31 takes place, is not fastened, after which the deformable sealing element 31 can be pulled out on this unfastened broad or long side. The non-attached wide or long side of the stamp plate 12 can then be attached, for example by a material connection and application of an adhesive layer or snapping an edge strip 52 into a recess in the frame 15, etc.

A possible sequence of the removal process of the sealing element 31 is shown in FIGS. 5 to 7. In FIG. 5 the assembled stamp cassette 2 is in the state provided with the sealing element 31, in FIG. 6 the removal or removal process is shown and in FIG. 7 the stamp cassette 2 no longer has a sealing element, it is thus finally assembled.

To remove the sealing element 31, the latter preferably has an engagement element 41 for handling, which is formed, for example, as a tab 42, via which the locking element 31 can be removed from the stamp cassette 2 or the body 11. For example, the tab 42 is formed by a material extension of the sealing element 31 which, even after the stamp plate 12 has been installed in the receiving opening 16, extends in regions outside the receiving opening 16, in particular in the region of the contour surface 20 of the frame 15 in the direction of end faces 43 and the end faces 43 are exceeded by the engagement element 41 over a dimension 44. Thus, after attaching the stamp element 12, it is possible to grip the engagement element 41, so that By exerting a tensile force on the engagement element 41, the sealing element 31 can be removed from the stamp cassette 2.

After removal of the sealing element 31, the ink stored in the body 11 can at least be continuously porous over the thickness 30 of the stamp plate 12

Areas are transferred, thereby providing ink on the printing surface 28.

8 and 9 show a further embodiment variant, in which the receiving device 13 is connected to a fastening means 39 formed as a holding frame 45 via an adjusting device 46.

In the exemplary embodiment shown, the adjusting device 46 is formed by a hinge arrangement 47, via which the holding frame 45 can be pivoted about a pivot axis 48 along an enveloping circle 49, so that the holding frame 45 is arranged in the manner of a flap on the receiving device 13. Thus, the receiving device 13 and the holding frame 45 are formed in one piece, a one-piece design formed from a uniform material, for example by a film hinge formed by means of a material recess in the area of the adjusting device 46, also being possible in a particularly advantageous embodiment.

In the exemplary embodiment shown, the holding frame 45 is provided with an opening 50 which is designed to receive an elevation 52 formed in relation to an edge strip 51 of the stamp plate 12. A contour surface 53 of the holding frame 45 delimiting the opening 50 therefore has essentially the same contour as a circumferential surface 54 of the elevation 52, a thickness 55 of the holding frame 45 compared to a height 56 of the

Survey 52 is lower. A peripheral surface 57 of the edge strip 51 of the stamp plate 12 has a width 58 and a length 59, which are each greater than a width 60 and a length 61 of the opening 50.

A fastening of the stamp plate 12 to the receiving device 13 can thus be achieved by placing the bearing surface 22 of the stamp plate 12 on the end faces 43 and / or the top surface 38 of the sealing element 31 and then by pivoting the open holding frame 45 which is in the release position into one Locked position clamping surfaces 62 contact an edge strip surface 63 of the edge strip 51 of the stamp plate 12, the protrusion 52 extending in the opening or projecting through it in some areas over a dimension 64. In this case, the stamp plate 12 is formed in the manner of a cover which closes the receiving opening 16 and which is fastened to the edge strip 51 by the holding frame 45.

The holding frame 45 can be fixed to the receiving device 13, in particular its frame 5, by any fastening means 65 or locking devices known from the prior art. In a simple embodiment, the holding frame 45 is clamped or locked in the receiving opening 16. This can be done, for example, in such a way that one or more protruding locking elements 66 are formed on the holding frame 45 as fastening means 65, which are formed in oppositely designed locking recesses 67 on the frame 15 engage with the holding frame 45 closed. Furthermore, locking or snap elements for connection - an example shown in dashed lines in FIG. 8 -, adjustable sliding or locking devices, etc. can be used as fastening means 65.

10 shows a stamp cassette 2, the stamp plate 12 attached to the receiving device 13 being processed by a marking device 68.

The processing of the printing area 27, in particular in the area of the stamp surface 28, of the stamp plate 12 is preferably carried out by a so-called “flash method”, in which radiation 69a is supplied to the printing area 28 via an exposure system 69, as a result of which in the area of the stamp area 28 generated thermal energy closes the ink-permeable pores of the porous material by arranging a matrix

70 between the exposure system 69 and the stamp surface 28, the radiation passage to the stamp plate 12 can be fixed so that the pores of the stamp plate 12 remain open in the areas in which no radiation is incident and in these areas ink through the thickness of the stamp plate 12 to the printing surface 28 can flow and thus definable stamp identifications can be produced in accordance with the form of the die.

The marking device 68 further comprises a radiation-transparent, in particular transparent, printing element 71, which has a printing surface 72 - according to the arrows 73 - exerts a compressive force on the stamp surface 28, whereby the material of the stamp plate 12 is compressed. Such a compression of the material is required in the materials usually used for the stamp plates 12 in order for the flash method mentioned to function in order to provide sufficient energy to close the pores. In order to ensure sufficient compression of the stamp plate 12, it is possible that

Pressure element 71 has an elevation with such a peripheral contour so that the pressure surface 72 can be moved into the receiving opening 16 of the receiving device 13, whereby the stamp surface 28 can be pressed below the end face 43 of the frame 15 for additional compression. The circumferential contour of the elevation on the pressure element 71 can essentially be that of the circumferential surfaces 54 of the elevation 52 of the stamp plate

12 correspond.

In the embodiment variant shown in FIG. 10, the stamp plate 12 is identified in order to produce an individual stamp impression in the already assembled state of the stamp cassette 2. The sealing element 31 is preferably still arranged in the stamp cassette 2, with the stamp plate 12 also being processed by the Labeling device 68 would be possible with the sealing element 31 removed.

The problem now arises with the compression of the stamp plate 12 in the state inserted into the receiving device 13 that permanent compression of the stamp plate 12, which can be up to 40%, for example, and / or compression of the body 11 causes the stamp surface 28 the end face 43 of the frame 15 no longer protrudes and thus the generation of stamp impressions only deteriorates or is no longer possible, as is indicated in broken lines in FIG. 10. To eliminate this problem, at least during the marking process by the marking device 68 in the

In the area of the stamp plate 12, a device 74 for balancing forces is arranged, it being noted at this point that the device 74 for balancing forces to form a mounting system and its components or exemplary embodiments may be the subject of an independent solution according to the invention.

It should be noted at this point that it is of course possible that, instead of the “flash method” mentioned, the stamp plate 12 is identified using other methods known from the prior art, for example engraving or material removal by laser. work, mechanical processing, etc., can be done.

In the exemplary embodiment shown in FIG. 10, the device 74 is formed as a stiffening element 75, the stiffening element 75 being assigned to the stamp plate 12 in the manner of an insert which remains in the latter even after the marking has been carried out, or as a separate part of the latter in the receiving device 13 is formed (as shown in Fig. 10). If the stiffening element 75 is designed separately, it can be fastened to the frame 15 and, for example, engage in grooves formed on the contour surface 20 and thus be fastened in a vertical position, the stamp plate 12 being arranged or being able to be arranged above the stiffening element 75.

In order to ensure an ink passage to the stamp surface 28 despite the stiffening element 75, the stiffening element 75 is designed, for example, as a lattice or perforated plate-like structural element 76 or through one of the several stiffening ribs, so that one or more passage openings 77 are formed for the ink , With such a

The compression of the stamp plate 12 can be limited at least to the region above the stiffening element 75 and displacement of the stamp plate 12 in the direction of the base plate 14 of the inhalation device 13 can be avoided or at least reduced.

FIG. 11 shows a top view of the stamp plate according to FIG. 10, the grid-like structural element 76 with the passage openings 77 being arranged in the stamp plate 12.

12 and 13 a further embodiment of a device 74 or stamp cassette 2 is shown, in which the sealing element 31 and the egg device 74 are simultaneously formed by a counter-holder 78 for balancing the forces, i.e. only one component for sealing the body 11 and the balancing of forces is required when marking the stamp plate 12.

It is the sealing element 31 or the device 74 as a rigid or rigid

Sliding plate 79 formed, which is slidably guided in a linear guide 80 of the receiving device 13 - according to the arrow 81. The linear guide 80 is preferably formed as a groove 82 formed in the contour surface 20 of the receiving opening 16, in which the slide beplatte 79 is held in a fixed position in the normal direction on the base plate 14. The frame 15 has on its longitudinal or broad side an insertion slot 83, via which the sliding plate 79 can be inserted into or removed from the groove 82. Thus, the cover surface 38 of the counter-holder 78, which is simultaneously formed as a sealing element 31 and device 74, produces the one produced during compression by the pressure element 71

Compressed force absorbed and compensated for without the stamp plate 12 being displaced into the region of the base plate 14 of the receiving device 13. The fact that the sliding plate 79 is simultaneously designed as a sealing element 31 that seals the ink-impregnated body 11 enables the stamp cartridge 2 to be produced cost-effectively and efficiently.

It should be noted at this point that a material with higher rigidity and at the same time porosity can be used for the stamp plate 12 to compensate for the pressure force generated by the marking device 68. The higher stiffness can be used by a material from scratch, a material with a high modulus of elasticity, etc. Furthermore, the ink-impregnated body 11 can be made of a rigid material which is not or only slightly compressible, e.g. porous or capillary metals such as aluminum, which also serves as an ink storage for stamp ink, are formed.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the stamp cassette 2, this or its components have been shown partially to scale and / or enlarged and / or reduced.
