The invention relates to the printer, in particular to the printer Registrar speed (tachograph) for commercial vehicles, comprising a housing, a printing block, block media placement media, and the unit of media contains the holder and, together with the holder is made movable relative to the printing unit in the direction of entry into the working position and opposite to the direction of input to output from the working position, and can move at least partially out of the housing; a holder in the form of a retractable cover has a first side guiding elements, which interact with the second guide elements so that the holder can move in the direction of insertion and can be extended out of the housing opposite to the direction input.

Such a device is already known from German utility model 299 20 901.6, which refers to the tachograph in the form of a flat rectangular design. thermal printing head and a transport roller for transporting print media, wound in a bobbin, at the conclusion of the holder from the housing of the printing device, can be spatially separated from each other. The basis of this design is the need that the media could simply and with a minimum of manual operations to be replaced or enrich the sterile, without accurate and complex mechanics of the transport block for media and printing unit.

However, the technical realization of this idea of the invention has been problematic in the past. If the transport block for print media and the printing unit when opening the case to replace the media or roll of paper tape are separated from each other and then are connected to each other, even slightly changed the position of the rolling unit transportation negatively affect the print result. On the basis of only one play installation required to ensure the mobility of the transport block, the exact playback position of the transport unit relative to the printing unit is a purpose contrary to the requirement of the mobility of the transport block. The disadvantages of the solutions known from the prior art, and the problems are compounded by the additional due to the usual technological tolerances, which is from the point of view of economy are invariant. Necessarily required clearance to ensure mobility in conjunction with the invariant technological tolerances leads to unacceptable results in print quality.

From out of Germany application DE 40 05 810 A1 is already known thermal printing device, in which the change of the medium, due to the requirements of the th refills infinite media, it is extremely difficult for the user. In European patent application EP 1 103 927 A2 disclosed tachograph with built-in printing device, and printing device together with the tray to accommodate media can vytaskivatelya to change the media from tachograph like pull-out compartment. The change of the medium in this case is rather complicated, because the media must be filled in the printing unit is in the front of the drawer compartment. More than a simple change of the medium is ensured described in published international application WO 02/063571 A1 placing the printing device relative to the unit of media in the housing of the tachograph, and block media made movable relative to the printing unit for the nomination of the body like the retractable compartment. However, this design requires to ensure the required quality of printing is very high precision guides for block media similar to those used for pull-out compartments.

Based on the problems and deficiencies inherent in the prior art, the object of the invention is to provide a printing device in which the unit of media designed to accommodate media, made movable relative to the printing unit and at the same time provides a seal adequate quality.

In accordance with izobreteniya problem is solved by means of the printer or embedded in the tachograph of the printing device, accordingly, paragraphs 1 and 22 of the claims. In dependent clauses characterized further preferred embodiments of the invention.

The invention allows to solve existing in the prior art the problem of compensation of clearances and tolerances in the guide rails of the transport block, movable relative to the printing unit, bypassing ideas, namely, to the position of the transport block after each interval of movement, to obtain good print quality, try to recover with sufficient accuracy in the construction as a whole. Instead, in accordance with the invention, only the printing unit is positioned relative to the holder unit of the carrier with sufficient accuracy, and the combination of both of these blocks can be placed in the overall design of the printing device with relatively large tolerances in the installation. This option is provided, in accordance with the invention in that the printing unit is in the overall design of the printing device is made movable and can be aligned with unit carrier, when the latter is pushed into the housing. Without the use of associated high cost low tolerances for structural elements of the guide holder in this way for the first time it became possible to combine good quality printing with UD the service by changing the print medium in a printing device of the above type.

The preferred way block carrier includes a holder, which is relatively printing unit is made movable in the direction of entry into the working position and opposite to the direction of input to output from the working position and can be extended at least partially out of the chassis. This holder may be used for positioning of additional structural elements and consists, preferably, of a stable material, which, when respectively rigid static performing substantially prevents inadvertent deformation.

To the printing unit relative to the print media has always been at the distance required for a good seal, it is advisable that the printing unit in the corps was moving in the direction of insertion and is opposite to the direction input. In addition, it is expedient to provide for different degrees of freedom for mobility, also perpendicular to the direction of insertion, in order to adjust the position of the print media when applying. Additionally it is expedient, if the printing unit also has a degree of freedom corresponding to the transfer, so that the oblique setting of the unit of media in relation to pachatusan unit can be adjusted when applying. Thus the so-called floating installation of the printing unit in to use, which share the above-mentioned degrees of freedom, it very much helps to ensure print quality.

The implementation of various preferred degrees of freedom are implemented through appropriate, at least one elastic element, which force presses the printing unit is opposite to the direction input, so that this force presses the printing unit to the holder at its input. The preferred elastic image(s) element(s) made(s) in such a way that there have been many degrees of freedom, or the printing unit is installed as a floating image.

The preferred implementation of the invention provides that the printing unit has a first area of contact and the housing has a second area is tight, and the printing unit by the force of the elastic element, the first area of contact is moved towards the second zone adjoining; in the rest position, which is not a working position, the first zone of the seal adjacent to the second area is tight, and the printing unit by the elastic force of the spring element in such a way is clamped between the elastic element and the second area is tight. Corresponding to the invention the clamping of the printing unit in the housing by the elastic element and the engagement zones of contact has the advantage that the printing unit is permanently fixed in position and cannot perform any uncontrolled movement in the housing. This way you can avoid damage of the printing block.

Another practical implementation of the invention provides that the holder has a first area of contact, the printing unit has a second zone of contact, and the first and second zone adjoining thus interact with each other that when the movement of the holder in the direction of entering the first zone of contact with the second zone of contact, respectively, pairs are in contact. In this embodiment of the invention correspond to the advantages of the invention are particularly, as a single connected with design blocks aligning functional structural elements relative to the respective zones is tight enough to ensure a satisfactory method of operation of the printing device. Along with this, the plane of the contact can be made with relatively small dimensions, relative to the planes of the guide holder that minimizes the cost of manufacturing planes fit with close tolerances.

In order not only had high accuracy on the position of the printing unit relative to the carrier in a direction normal from the plane fit, but also high precision relative positioning of the printing unit with respect to the holder perpendicular to n is malam planes fit, it is advantageous if the printing unit has at least first centering element holder has at least one corresponding first centering element of the second centering element, so that the holder and the printing module in the housing when moving the holder in the direction of insertion through the centering elements are centered in position relative to each other in the direction of explode and/or at least in the direction perpendicular to explode. The centering elements may consist of pairs of interacting beveled or conical planes or cones, which interact with corresponding grooves of the conical shape. It also may be preferred if the centering element performs centering only function in one direction perpendicular to the normals of the planes fit or normal to the direction of movement. In addition, suitable also is a fork of the centering element, which interacts with the cylindrical mating element so that the side surface of the cylinder is directed facing each other shoulders fork positioning element.

Appropriate systemic separation of the printing device components that are fixed to the movable holding the barely, and components that are attached to other elements of the printing device, is obtained in the case when attached to the holder unit of media has a positioning element for reel paper tape and the transport block for the paper mentioned coil.

In order for the holder during operation was permanently fixed in the housing, it is advisable to block the carrier or holder was made to lock in position by means of the fixing unit. A fixture holds the unit of media in the working position in a fixed position in the housing. In asfixiando the state unit of the carrier or holder has the ability to move at least partially out of the chassis. Movable elements of the locking unit must be a fixed to the holder of the components of the holder. Some additional stroke, which requires locking mechanism in order to achieve the state of fixation or stop in this position compensated in accordance with the invention by means of a movable fastening of the printing unit in the building.

The stationary elements of the locking unit, which interact with the possibility of fixation with movable elements on the holder, preferably rigidly connected with the housing. That is they way the block media shockproof fixed in the case.

In another embodiment of the invention the locking element has at least two retaining element. These preferably stationary holding elements interact, respectively, with a movable locking element, for example made in the form of a latch, hook, rolling pin. The preferred way of retaining elements are located symmetrically on the power of the media and/or with respect to the elastic element, which applies a force to pachatusan block opposite to the direction input.

To improve the reliability of operation it is advantageous if the movable elements interact with the sensor, which determines the state of fixation, in which the carrier or holder and the printing unit in the direction of explode fixed relative to each other, and/or state is released, in which the carrier or holder and the printing unit is not fixed relative to each other in the direction of explode. Thus, it is expedient if the sensor is connected with the Central control unit, which by means of the sensor polls the state of fixation and depending on the reports ready.

As in the preferred conditions for the use of the invention of the printing device under adverse operating conditions and polluted environment can the future rapid contamination of the functional elements of the printing device, it is advantageous if the holder with the housing in the working position to the maximum extent sealed from exposure to the environment.

From the point of view of a large tolerance on the installation and in the interests of fully automated mass production it is advantageous if the printing device has at least one guiding device, which has at least two first guide element, which is placed on the holder, and two second guide element, which correspond to the first guiding elements on the holder so that the holder when moving in the direction of input or opposite to the direction input is routed through the guide device, and the second guiding elements mounted on the average of the connecting element. This ensures a well-defined distance between the guide elements, and play installation for the holder does not depend on other structural elements. Thus, the holder block and the printing unit can be tested and outside completely ready device.
