The invention relates to a tachograph with an open or openable housing, in which a printing device having a thermal print bar and a receptacle for a rotatable about a rotation axis roller of the printing device can be printed tape-like printing material is arranged, with one of the thermal pressure bar parallel gege ^¬ nüberliegenden to a roller shaft rotatably driven transport roller, through which can be acted upon on the thermal printing strip before ^¬ beifuhrbare printing material in contact with the thermal printing bar, wherein the area of the receptacle of the loading printable printing material from the outside can be achieved.

In such tachographs, so-called digital tachographs, driver and vehicle-related data are printed on a ribbon-like printable printing material. For feeding and archiving, memory chips are arranged on a chip card.

It is known to insert the ribbon-like printable Druckmateri ^¬ al as a role in a slide-out drawer, with a drawer pushed a small end piece of the

Print media out of a slot in the device. He follows ^¬ expression, the printed printed material migrates out of the slot to the outside.

Through the slot, the inside of the device is always connected to the outside, so that dust and moisture can easily penetrate into the device.

The drawer requires a complicated rail guide and a mechanism for opening the drawer. The printing device requires a complex structure with a resilient mounting of the thermal pressure strip for Toleranzaus ^¬ same. Furthermore, the transport roller has to be arranged with its drive in the drawer, which defektanfallige flexible electrical connections to a system electric ^¬ nik of the tachograph requires supporting circuit board.

The object of the invention is therefore to provide a tachograph of the type mentioned above, which avoids these disadvantages, allows a simple Bestucken with a role of Druckma ^¬ terials and has a simple structure.

This object is achieved according to the invention in that the housing has an opening directed to an operator side, the thermal printing bar fixed angeord ^¬ net in the housing and the transport roller can be lifted from the thermal print bar and that the axis of rotation of the roll of printable printing ^¬ material and the transport roller are out ge ^¬ directed to the operator side.

Due to this design no flexible electrical wires are required, which lead to the thermal pressure bar.

The arrangement of the axis of rotation of the roll of the printable printing material is directed to the operator side, so that re-equipping with such a roll is possible in a simple manner without the need for a drawer to be pushed out and pushed in.

As a receptacle for the roll of printable printing material, the housing may have an input side of the thermal print bar and transport roller arranged printing material chamber.

In this case, a fixed positioning and low-friction rotation of the roller is achieved in that in the Druckma ^¬ terialkammer a free to the operator side protruding printing material aldom is arranged on which a roll of printing material is freely rotatably arrangeable.

The housing has export side of thermal printing bar, and a transport roller Printed material chamber, so the printed printing material is there to a removal aufgenom ^¬ men and does not depend as a band of material in the passenger compartment of the motor vehicle inside.

If the printed material chamber has a round, in particular a circular, cross-section, into which a demand slot leads, which leads from the contact area of the transport roller on the thermal print bar to the printed material chamber, the printed printed material is forcibly rolled up after the printing process and thus requires only small space.

In this case, the impact process is particularly favorable when the request slot opens at least approximately tangentially into the round printing material chamber.

To protect against dirt and moisture, the opening of the housing can be closed by a closure.

This results in an easy handling for opening and closing, when the closure is a closure flap which is pivotally gela ^¬ siege around a extending along an edge of the rectangular or square opening flap axis.

In order to be able to import at the same time the free end of the print material from the operator side between transport roller and thermal print bar at a Neubestuckung with printing material, the transport roller can be rotatably mounted on a carrier which is movable toward the thermal print bar and away from the thermal print bar. Is the transmitter strike the thermal print bar to federbeauf ^¬, the transport roller applied evenly over its entire length with a certain force the Druckmateri ^¬ al against thermal bar.

For this purpose, the carrier may be movably guided in a guide shaft of the housing and / or on fixed guide elements in a simple manner.

If the carrier has a drive device for the rotary drive of the transport roller, a simple rotational transfer can take place from the rotary drive to the transport roller.

To drive the movement of the carrier and the transport roller, the carrier can be driven by a manually actuatable adjusting device on the thermal print bar to and from the thermal ^¬ pressure bar away movable.

An automatic lifting of the transport roller at an opening of the shutter and an automatic lowering upon closing of the closure flap occurs when the adjusting device is coupled to the closure flap, by the closing movement of the closing flap a Be ^¬ movement of the support for the thermal printing strip to and through a Opening movement of the shutter, a movement of the Tra ^¬ gers of the thermal print bar is generated away.

For this purpose, in a simple training on the housing in the direction of the operator side movably driven adjustable slide be guided, which is coupled to the flap by means of a coupling and the carrier by means of a cam ^¬ drive, preferably the coupling with her one directed to the operator side End is articulated at a radial distance to the flap axis and further preferably with its second end directed to the adjusting slide at the end directed towards the operator side of the adjusting slide. To transmit the movement of the adjusting slide on the carrier, the adjusting slide can have a slide track, which extends in the longitudinal extension of the adjusting slide from a closer end to a carrier to a remote end of the carrier into which a sliding block of the carrier engages.

Are a plurality of guide paths one after the other in the extension direction of Langs- Verstellschiebers in Verstellschie ^¬ about arranged engages in each of which a sliding block of the support, these Bewegungsubertragung occurs particularly evenly and verkippungssicher.

In order to keep the carrier stable in the end positions of its movement stroke, the end closer to the carrier and / or the end of the link path which is further away from the carrier can extend parallel to the roller axis.

Without additional components, the adjusting slide is displaceably ^¬ bar guided when the adjusting slide is guided displaceably in a Fuhrungs- slot in a wall of the housing, preferably and in a particularly simple and safer manner the adjusting slide on opposite sides Fuhrungsnuten, wherein the web formed between the bottom of Fuhrungsnuten is einfuhrbar in the Fuhrungsschlitz.

If the thermal print bar is arranged on a printed circuit board which completely or partially carries the system electronics of the tachograph, then no flexible electrical connections between the system electronics and the thermal print bar are required.

In this case, it leads to a simple mountability when the thermal print bar protrudes through a recess in a wall of the housing, wherein the circuit board is arranged on the outside of the wall of the housing. An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it

FIG. 19 shows a front view of the housing of the tachograph according to FIG. 1.

The tachograph shown in the figures has a home 1 with a rectangular cross-section in DIN radio format.

As FIG. 1 shows, the housing 1 can be inserted into a corresponding shaft in the instrument panel 2 of a motor vehicle and covered by an aperture frame 4 on its opening 3 directed towards the operating side.

Below the underside of the opening 3, an insertion slot 5 is formed in the cover frame 4, in which a chip card is einführbar containing memory chips for storing data such as driver, vehicle, travel and working time data. The opening 3 can be closed by a closing flap 6, which is pivotably mounted around a flap axis 7 extending horizontally along the upper edge region of the opening.

The interior of the housing 1 is divided by a Fuhrungsschacht 8 in a right printing material chamber 9 and a left Be ^¬ drucktmaterialkammer 10, which is arranged centrally vertically in the interior.

Here, the Fuhrungsschacht 8 is formed by two spaced zuein ^¬ other arranged partitions 11 and 12.

On the side facing away from the operator side, the housing 1 is closed by a housing floor 13. On the Gehauseboden 13 a mandrel-like printing material dome 14 is arranged, which projects approximately centrally into the printing material chamber 9 freely to the operator side.

On the printing material dome 14 is not shown roller print material freely rotatably arranged with its tubular central opening.

The printed material chamber 10 has a circular cross-section as seen from the operator side.

In the between the dividing walls 11 and 12 of the Fuhrungs- shaft 8, a carrier 15 is guided vertically displaceable.

The vertical guidance is supported by guide projections which extend at a distance from one another perpendicularly to the partition wall 11 and protrude from the plane of the partition wall 11 on the guide shaft and project into corresponding guide grooves 17 of the carrier 15.

In a formed at the lower region of the carrier 15 Transportwalzenkammer 18 is a transport roller 19 to a parallel to the printing material dome 14 directed towards the operator side roller shaft 20 rotatably mounted.

In the area of Fuhrungsschachts 8 in the lower wall 21 of the housing 1 is a through recess 22 is formed of rectangular cross section which substantially extends over the Gehau ^¬ setiefe and protrudes through which a pressure strips exchanger 23rd

Fuhrungsschachtseitig is on the Druckerleistentrager 23 of the transport roller 19 opposite a thermal print bar 24 is arranged.

The Druckleistentrager 23 is with its the Thermodruckleis- te 24 opposite side on a circuit board 25 be ^¬ consolidates, which in turn is arranged on the outside of the lower wall 21 and ^carries a not shown Systemelektro ^{¬ technology of} the tachograph.

The transport roller chamber 18 opposite end portion of the carrier 15 is formed as upwardly open carrier chamber 26 ^¬ , at the bottom 27 a two-armed leaf spring 28 is fixed with its central region.

The spring arms 29 of the leaf spring 28 are inclined upwards and rest with their free ends on the underside of an adjusting slide 30, so that it is resiliently acted upon by the carrier upwards away.

The adjusting slide 30 has guide grooves 31 at its two sides facing the dividing walls 11 and 12.

With its upper region, the adjusting slide 30 protrudes through a guide slot 33 formed in the upper wall 32 of the housing 3, so that the side walls of the guide slot 33 project into the guide grooves 31. Characterized the adjusting slide 30 toward the operator side and from the operator side is displaceable away ge ^¬ leads.

At the same time it forms a Abstutzung for the spring arms 29 of the prestressed leaf spring 28th

At its end facing the operator side end of which is a coupling to the damper spindle 7 extending second coupling shaft 35 pivotally mounted 34 at its second end about an axis parallel ^¬.

With its first end directed towards the operator side, the coupling 34 is pivotably articulated on the closure flap 6 about a first coupling axis 36 extending parallel to the flap axis 7 at a radial distance.

As a result, in the case of an opening operation of the closure flap 6, a pulling movement toward the operator side and, in the case of a closing operation, a pressure movement away from the operator side are exerted on the adjusting slide 30.

From each other two guide tracks 37 are formed on the adjusting slide 30 at a distance, which extend 30 distant from a transmitter 15 near the end to a ^¬ ren the transmitter 15 in the end of the Langserstre- ckung Verstellschiebers.

In the slide tracks 37 engages parallel to the flap axis 7 in each case a sliding block 38 of the carrier 15 a.

Both the ends closer to the carrier 15 and the ends 40 of the link tracks 37 remote from the carrier 15 extend parallel to the roller axis 20.

When the closure flap 6 is closed (FIG. 2), the sliding blocks 38 are located on the end 39 closer to the carrier 15 in the slide tracks 37. The carrier 15 with the transport roller 19 has thereby assumed its most lowered position, in which the transport roller 19 is on the thermal print bar 24 in circulation.

If the closing flap 6 is swiveled over its half-open position (FIG. 3) into its completely open position (FIG. 4), a pulling movement of the adjusting slide 30 towards the operating side takes place.

Since the exchanger with 15 him the sliding blocks 38 may not Be ^¬ movement by lead to or from the operator side away thereby move the sliding blocks 38 from the transmitter 15 nä ^¬ heren end 39 to the transmitter 15 remote end 39 of the guide tracks 37th

In this case, the carrier 15 is raised against the force of the leaf spring 28 and the transport roller 19 is lifted from the thermal pressure bar 24, so that a gap 41 between the thermal pressure bar 24 and transport roller 19 is formed.

At the height of this gap 41 is located in the dividing walls 11 and 12, an approximately horizontally extending request slot 42 which connects the printing material chamber 9 with the printing material chamber 10.

If now a roll of bandar ^¬ term printing material attached to the Druckmaterialdom 14 with open flap 6, so the free end portion of the ribbon-like printing material can be inserted transversely into the Einforderschlitz 42 and the gap 41, wherein the free end of the tape-like Druckma ^¬ terials protrudes into the printing material chamber 10.

By closing the closure flap 6, the carrier 15 also lowers and the transporting roller 19 resiliently acts on the printing material against the thermal pressure strip 24. By an unillustrated driving means, preferably ^¬ as an electric motor, the transport roller can now 19 ge ^¬ optionally via a gear rotatably driven and since ^¬ modruckleiste by the media for data recording of the printing-material chamber 9 to the Printed material chamber 10 via the thermo- required 24 ,

Drive device and transmission are arranged in the carrier 15.
