The invention relates to pachatusan unit for hand stamps, respectively, for installation in the manual stamp, in particular samoobrazovyvalas stamps, with at least one print ribbon, which is laid on top of the drive wheel, which is mounted for rotation in bearings and provided with the adjusting wheel, preferably in the form of a single whole with him, according to the restrictive part of paragraph 1 of the claims.

Further, the invention relates to the drive wheel for such a printing unit, at least one print ribbon, which in the assembled position laid on top of the drive wheel, the drive wheel which has a profiled body of the wheel and United with him, preferably with him as a whole, the installation of the wheel.

Known equipment samoobrazovyvalas stamp printing units, which have one or many printing tapes to swap letters, with these print ribbon are in the form of a loop in the printing unit and partially encircle the drive wheels, which are connected with the adjusting wheel to periodically move the print ribbon in a printing unit for transferring the relevant swap characters in position imprint. For example, the kind with moorseville stamp with this printing unit is known from EP 723874 A. Usually made in the form of a loop printing ribbon in the printing unit are combined with fixed letters, and access to the drive wheels, respectively, to their mounting wheels to install the appropriate print ribbon is only possible in a limited spatial region. And when you swap the drive wheels of the finger may contact printing ribbons, which were moistened stamp ink by a previous use of a seal, causing the fingers will be stained. To prevent this possibility, the diameter of installation of wheels may be provided in a larger size, which, however, will in addition to the undesirable increase the demand in place inside the stamp. In addition, the installation of the wheel driving wheels usually are thin, in order to occupy less space in the direction of the axis of rotation of such a printing unit, besides the fact that when the thicker mounting the wheels, the distance between swap characters when they are on adjacent printing tapes, may be undesirable large with a corresponding impression. This leads to the fact that installing drive wheels, respectively, printing tapes, cannot be carried out easily that the installation of the wheels when moving into your fingertips, and that p is oshodi in the case when the installation of the wheel, as usual, at its perimeter provided with a gear or have a pattern.

From AT 379 U1 it is known that for the protection from pollution of the finger when moving the adjusting wheel includes installation of a protective film on the print tape; this protective film having slots for the passage of installation of wheels, for fixing is inserted into the slot of the base transverse part, however, the sealing protective film is unsatisfactory.

In DE 20309613 U1 shown next printing unit, in which there is a cover that is on the end sides of the triangular slots when installing the cover on the base part of the printing unit locks provided on the shelves this supporting part adjacent to the base directed along the axis inside the locking tabs. The disadvantage to this, among other things, is that the lid with latch and possible subsequent installation of the cover is quite difficult, because the elastic deformation of the interacting locking elements may be limited, this can easily rupture of the end sides and the walls have the form of a cap cover.

The objective of the invention is the creation of the printing unit, and the drive wheel to him, which would provide the ability to simply, conveniently and comfortably secured and shoot cu is the Cabinet without the risk of damage and, in addition, avoid obstacles comfortable permutation printing ribbons associated with the risk of contamination of the fingers, and would exclude the possibility of cutting edges of the mounting of the wheels to the ends of her fingers.

The task is solved by means of the printing unit, as defined in paragraph 1 of the claims, as well as drive wheel for him, as defined in paragraph 11 of the claims. Preferred embodiments of the and improvements are the subject of dependent claims.

According to the invention can be simply prevented by the contact of the finger print ribbons bearing the stamp paint, thanks to having the ability to snap into place and is securely fixed to the cover in the form of a cap which closes the print ribbon in a problem area, but they or drive wheels, respectively, more precisely their installation wheels remain available through slotted holes. Cover due provided in accordance with the invention, the locking connection can be installed very easily and when you desire to act quite differently than in the case of the cover fixing screw, so it makes it easy to carry out, for example, cleaning of printing tapes or replacement.

This, in particular, is achieved midrange is tons of space and form locking elements, as provided according to the invention, as in this case, the locking elements are easily accessible and provide a certain elastic deformation.

To achieve latching or snap-on connection was preferred, if protruding from the front side of the cover elements are shaped trunnion locking tab.

For a comfortable achieve the locking connection is also the preferred implementation of the cap together with the specified elements from providermessage synthetic material, for example Acrylonitrile-butadienestyrene (ABS) or polystyrene (PS). It is preferable that the cover together with the above elements are in the form of a one-piece molded part.

On the other hand, in relation to support driving wheels for the print ribbon is preferable that the supporting portion together with the locking sleeves are made of a relatively hard synthetic material, such as, for example, Polyoxymethylene (POM). In this case also and the supporting portion together with locking nozzles may preferably be made as one-piece cast part.

A particularly preferred method of execution proposed in accordance with the invention, the printing unit is characterized by the fact that the supporting part through quotation screws connected with BA the new part, which is a through hole corresponding in position, which is the imprint, letter print ribbon, the lid having a fixation with the supporting part, when moving the supporting part can be moved together with her relative to the base part and the support part has on each end of the shelves are made outside between the retainer nozzles open side of the socket head adjusting screw, the socket has a bottom portion formed by fixing nozzles, with a through hole for the stem of the screw, which is open through the side slot. With such design, the cover having a fixation with the supporting part, when moving the supporting part can simply be moved together with her relative to the base part. At a basic part of such a printing unit can be mounted plate in the shape of a frame, in particular from rubber with a permanent stamp the letters. The base part can also be made of rigid synthetic material, such as, for example, of ABS or POM.

Drive wheel (each respectively) preferably has a soft area on the perimeter, which adjoin the fingertips, compared with a more solid synthetic material the rest of the drive wheel, in particular the building is and the wheels, and accordingly the inner region of the installation of the wheel. This eliminates the unpleasant feeling of cutting into the fingers when working with the appropriate installation wheel, however, due to the high transfer of force through friction there is the possibility of reliable permutations driving wheels without slipping the tips of the fingers. For internal connections having different hardness of synthetic materials was found that has the advantage that if the radial inner more solid part of the adjusting wheels are made with elements having the form of spokes between which extends a softer synthetic material.

Very nice soft synthetic material, which is applied to the outer peripheral region of the installation of the wheels, which is a thermoplastic elastomer. As more rigid synthetic material can be used, for example, PS, ABS, polycarbonate (PC) or a combination of such materials. It is preferable that the drive wheel is made in the form of a two-component molded parts.

Next, you can see performed relatively curved text card 24, provided with an upper rear W is item, this text card 24 provides a relatively large surface of the imprint on the front side, as on the upper side for applying the relevant information in the form of print, etc. Text card 24 may when installed in the observation window 22 is inserted through reliance on a locking plate 23 and with it fixed in the upper part 4B of the casing stamps by relying on its upper side, and when the lock of the strap 23 with a cross bridge 25 of the upper part 4B of the housing of the stamp.

Figure 1 additionally shows the latch 26 in the form of a push button on the handle 5, which communicates with the slot 27 in the tubular part 19, which gives a known fixing of the Executive arm 5 in a defined position relative to the housing 4 of the stamps.

As can be seen in figure 5-10, the printing unit 3 has, in addition to the base part 10, which is still referred to as the body of the text plate, the support portion 28, also called bracket housing, which is fixed on the base part 10 by means of quotation screws 29 with the possibility of height adjustment. The support part 28 is made preferably in the form of a one-piece casting with two shelves 30 and the base plate 31 connecting the shelves 30, while supporting strap 31 serves as a support printing ribbon 32 (for example, four printing tape to set the key to be printing date). Print ribbon 32 are thus respectively on top belonging to each tape drive wheel 33, 34, 35, 36, each of these driving wheels 33-36 has a body 37 of the wheel shaped like subcode circle and United with him, preferably with him at the same time, the adjusting wheel 38. Drive wheels 33-36 using axis 39, see figures 9 and 10, mounted for rotation in bearings 28 to allow movement of the print tape 32 with the installation of the wheels 38 of the drive wheels 33-36 manually on the desired date or even on the desired impression.

Installation or adjusting screws 29 are installed in the receiving slot 40 of the base housing 10, which has an internal thread, see figure 10, and the head 41 of the adjusting screws 29 are located in the open side of the slots 42 on both sides of the support part 28, while they when the installation is first inserted into the slots from the side through the slot 42 in the bottom part 42', while the rod 29' quoted screw 29 will not go in far enough to reach the slot 40 of the base part 10, however, he then goes through not shown in detail the penetration hole in a direction to the slot 40 in the base part 10. The upper side of the head 41 of the respective adjusting screws 29 in this case are available through the top hole is ment 43 of the slot 42 to the tool, in particular for a screwdriver (not shown), in order to implement the desired fixation and more fine-tuning.

Socket 42 formed on both end sides of the bearing part 28, on the outer sides, respectively, between the two nozzles 44 of the support part 28, and consequently pair of nozzles 44 are located symmetrically and in other respects for all of the nozzles provided almost the same performance. These nozzles 44 is formed by using, in particular, visible on Fig, 8A and 9 of the slots 45 (for fixing) fixing elements 46 and accordingly lower than they are fixing nozzles, and these fixing nozzles 44 are working together with is made accordingly with their interacting locking elements 47 on having the form of a cap cover 48 of the printing device. In particular, the locking elements 47 and cover 48 is formed having the shape of the trunnion lugs 49 on the elements 50 of the bearing part, which act on both end sides of the cover 48.

Cover 48, as mentioned, has the form of a cap with a U-shaped configuration in cross-section, and it has a slot 51 for mounting wheels or discs 38 driving wheels 33-36. These slots 51 extending from the top having the shape of an arc region 52 of the cover 48 in the region of shelves 53 of the cover 48. Using areas 54 between the slots 51 in the assembled position peracre which are stated print ribbon 32 (see 5), thereby preventing contamination of the fingers of a user when installing the print ribbon 32 over the driving wheels, respectively, with their installation disks 38 when involuntary touch printing tape 32 with stamp ink. The cover 48 may be simply fixing the image is fixed, i.e. the "closed with a click on the support part 28 by means of the elements 50, which are snapped into the locking elements 45 of the fixing nozzles 44, similarly it also can easily be removed from the supporting part 28 of the printing unit 3. Further, when the alignment reference part 28 relative to the base part 10, the cover 48 is automatically moved together, because it is installed on the supporting part 28, and not on the base part 10.

Drive wheels 33-36 made in the form of a two-component molded parts, compare figures 9, 11 and 12 (for the drive wheel 36 as an example), the housing 37 of the wheel preferably, and also the interior 55 of the respective adjusting wheel 38 is made of a relatively rigid material, the radial outer region, or area of a circle 56 adjusting wheel 38, in contrast, is formed from a relatively soft synthetic material. As a soft synthetic material, in particular, applied thermoplastic elastomer, on the contrary, for more stringent EXT is nna part of the driving wheels (the body of the wheel 37 and/or the internal region of 55) applies, for example, polystyrene (PS), copolymer based on Acrylonitrile-butadienestyrene (ABS), polycarbonate (PC) or a combination of these materials, such as, in particular, PC-ABS. External soft synthetic material by contact of the fingers with the alignment wheels 38 pleasant feeling and allows a very comfortable, easy rotation of the adjusting wheel 38 driven wheels 33-36. In addition, the perimeter of the installation of the wheels, as particularly seen in figure 11, may be provided with a corrugation or gear, to thereby improve engagement in addition to high friction soft synthetic material.

To the axis of the driving wheels 39 are preferably also used synthetic material, in particular POM; similarly from POM or similar relatively rigid synthetic material can be molded supporting part 28, equally, for example, SIP or of ABS molding can be manufactured and the base part 10.

For the cover 48 is preferably compared with the supporting part 28, is applied a few more soft synthetic material, in particular, we can talk about PS or ABS.

Preferably, the cover 48 is made in the form of a one-piece molded part.

As shown in figures 9 and 12, more solid interior region 55 of the drive wheels 33-36 in the field of installation disks 38 can be is made of frame elements 57 in the form of spokes, soft synthetic material outer region 56 extends into the intermediate space between these elements 57; thus can be achieved more durable connection of both components of the synthetic material in the manufacture of driving wheels 33-36.

How then, in particular, can be seen on figure 5, 9 and 10, the base part 10 has a lower frame portion 60 with a through hole 61 for letter printing ribbon 32 resting on the support bar 31, respectively, when performing print and on this frame part 60 is fixed, for example, by gluing rectangular plate 62 with the corresponding through hole 61 for letter printing ribbon 32. The plate 62 is composed of synthetic or natural rubber with approximately hardness (shore) from 50 to 55, and it is equipped with a fixed stamp characters, which are shown in figure 5.

As can be seen in Fig.9, the shelf 30 of the support part 28 have outer guide channels 64 that communicate with the respective longitudinal vertical guides 65 of the base part 10, so that when assembling and aligning guide supporting part 28 on the base part 10 and prevent its lateral displacement.
