Smart card holder system

The invention relates to a chip card receiving system, in particular for a tachograph in a motor vehicle, with a chip card receiving device having a receiving opening through which a smart card into a receiving ^¬ bay is einfuhrbar, wherein the chip card has a Datenspei- cherchip operating at completely in-the receiving shaft smart card with fixed contacts can be connected and with conductive tierbar an electronic reading and storing unit with a locking unit, the least having min ^¬ a locking member movable between a the receiving opening completely releasing unlocking ^¬ position and a the receiving opening partially closing lock position is movable, in which a fully inserted into the receiving shaft chip card is engaged behind by the locking element at its receiving opening end.

In such known chip card recording systems for tachographs, the chip card is completely drawn into the receptacle ^¬ meschacht and locked after complete collection by the locking unit. Thus, the chip card for manipulation can not be removed and is not accessible from the outside.

Over the life of the tachograph but a large amount of dirt and other contaminants is brought with the smart card in the interior of the device. Among other things, these foreign particles are also ^deposited on the contacts with which the data memory chip of the chip card contacts for reading and storing information.

In addition, there is the abrasion of the chip card by the entry and exit of the chip card. This leads to an impairment of the writing and reading ability at the contacts.

To clean the contacts a chip cleaning card is known loading, which corresponds approximately to the chip card and which has a loading in ^¬ movement direction of the smart card extending recess. In the recess, a slider is arranged movably guided, which has a cleaning field, and which is provided with ei ^¬ ner actuating tab which projects into the receiving shaft inserted chip card through the receiving opening to the outside, so that the slider manually reciprocates can be. As a result, the cleaning field cleans the contacts.

This cleaning card has a complex and therefore defective structure.

The object of the invention is therefore to provide a Chipkartenaufnahme- system of the type mentioned, which has a single fold, defektunanfalligen structure and a contact ^¬ allows cleaning with a locking unit provided with a chip card receiving device.

This object is inventively solved by the fact that a chip cleaning card is einfuhrbar in the receiving slot, the width and thickness of the chip card and having a smaller length than the chip card that ver in the locked position, the chip cleaning card by a corresponding amount in and against the import direction slidable and with a arranged on one or both surfaces cleaning field on the fixed contacts these along moving is moved, wherein one or more actuating tabs are arranged at one end of the chip cleaning card and by the gelungsstellung in the open position of the receiving opening to the outside protrude. By this design, the chip cleaning card can be easily formed and defektunanfallig.

For optimum cleaning of the contacts, first the chip cleaning card with the cleaning field facing the contacts is completely inserted into the receiving shaft. In the fully inserted position, the chip constantly cleaning card lost, the locking unit, so that the Verriegelungsele ^¬ element in its locking position and moves the up nahmeoffnung partially closes.

Through the open part of the receiving opening, the actuating tab protrudes outwards and can be grasped by an operator.

Since the length of the chip cleaning card is less than the length of the chip card, the chip cleaning card can be moved back and forth in and against the direction of insertion by means of the actuating tab despite locking, and the stationary contacts are cleaned by the cleaning field.

If the free end of the actuating tab projecting from the receiving opening extends on one or both sides beyond the width of the chip card, then only a correct import of the chip cleaning card is possible and it becomes

Imports of the chip cleaning card first with the tab ^¬ prevents tab.

The cleaning field may be a cleaning bag that is fillable with a liquid detergent.

Another possibility is that the cleaning ^¬ field is a microfiber field or a felt field.

An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it FIG. 1 shows a perspective view of a chip card receiving device with a chip card that has not been inserted,

Figure 9 is a perspective view of the chip cleaning ^¬ map of FIG. 5

The chip card receiving device shown has a carriage 1 with a boom 2, on which a rack 3 extending in the direction of insertion 4 of a chip card 5 is arranged. The carriage 1 is slidably guided between a receiving position (FIG. 1) and a contact position (FIG. 2) in a receiving shaft.

For this purpose, the chip card 5 is inserted through an insertion opening forming an insertion slot 6 of a fixed import part 7 in the carriage in its receiving position 1 until it abuts stop 39 of the carriage 1.

In a short further Einschiebebeaufschlagung the chip card 5 is an actuation of a second switch, not shown, and thus a draw of a second switching signal.

By this second switching signal, a reversible electric motor drive 8 is turned on in one direction of rotation.

Via a transmission, the drive 8 drives a drive pinion 9, which is in engagement with the one end of the rack 3 and moves the rack 3 and with it the carriage 1 in the con ^¬ tact position.

Since the smart card 5 is held by a clamping device of the carriage 1, it moves with the carriage 1 in the contact position.

If the contact position is reached, there is a Entkop ^¬ PelN of the drive pinion 9 of the rack. 3

But the drive runs 8 and begins at the end of a ^¬ zugsbewegung the chip card 5 has a rotary drive of a Stellhe ^¬ bels 10 to rotate clockwise about a transversely to the direction 4 of the smart card 5 extending axis. 11

A pin 12, which is parallel to the axis 11, engages in a cam guide 13 in the one end region of a locking lever. bels a 14 which extends adjacent the right side of the movement path of the carriage 1 and is pivotally ^¬ ^¬ bar in its middle Be rich about an axis parallel to the axis 11 pivot axis 15 °.

By the movement of the pin 12 in the link guide 13, the locking lever 14 is pivotally driven from its Entriegelungsstel ^¬ ment in its locking position in a clockwise direction.

On the locking lever 14, a locking slide 16 is slidably guided guided by an approximately radially to the axis 11 extending control 17 after the pivoting of the locking lever 14 in the locked position and is moved from a Entarretierstellung to insertion slot side out in a locked position.

Where the insertion slot 6 near end of the lock lever 14 is a one locking element forming INTERLOCKS ^¬ averaging part is fixedly arranged 18, which is pivoted by the pivoting of the lock lever 14 in its locking position mitge ^¬ while the outboard end of the fully retracted chip card 5 hook-like engages behind and thereby locked in the card receiving device.

The locking member 18 acts on the outer end of the chip card 5 with a ramp-like inclined to the import direction 4 contact surface 19, so that in the case of not completely retracted smart card 5 this by the Schwenkbewe ^¬ tion of the locking lever 14 in the locking position of the contact surface 19 with a movement component is applied in a ^¬ driving direction and fully inserted into the takeout apparatus Kartenauf-.

In this position, the chip card 5 is located with its front end to the stops 39 and is at its rear end engaged behind by the locking part 18, so that no Be ^¬ movement of the smart card 5 in or against the import direction 4 is possible.

On the locking slide 16 is about its side facing the insertion slot 6 directed end freely projecting a spring ^¬ arm 20 is arranged at the free end of both a beam interrupting flag 21 and a parallel to the axis 11 extending Fuhrungsbolzen 22 are arranged.

The Fuhrungsbolzen 22 projects into a Fuhrungsnut 23 Verrie ^¬ gelungsteils 18, which extends approximately parallel to contact surface 19.

As a result of the displacement of the arresting slide 16 from the unlocking position into the arresting position, the guide pin 22 is also displaced in the guide groove 23 so that the beam interruption tab 21 makes a movement with a movement component directed transversely to the insertion direction 4, transversely into the region of a light beam 24 moves and interrupts it.

The light beam is emitted in the direction of import 4 by a light source 25 in the form of an LED and is directed to a light receiver 26.

Light source 25 and light receiver 26 are arranged on a ortsfes ^¬ th printed circuit board 27.

The light receiver 26 is located in a light box 28, which is formed integrally with the import part 7.

In the beam path from the light source 25 to the Lichtempfan ^¬ ger 26 an aperture 29 is formed in the light box 28, so that the light beam 24 can reach the light receiver 26. In the locking position of the locking slide 16 but the beam interruption flag 21 is gefah ^¬ ren before the aperture 29 and interrupts the light beam 24. This leads to the fact that the light receiver 26 outputs a first switching signal, whereby the drive is stopped. 8

In the locked position, the locking slide 16 continues to lock the locking unit 32 consisting of locking lever 14, locking slide 16 and locking part 18 in its locking position.

In the contact position of the chip card 5, arranged on the chip card 5 data memory chip 30 is contacted with fixed contacts 31 of the card receiving device, so that the data of the data memory chip 30 can be read into a not illustrated ^¬ read and write unit of an electronic trip ^¬ writer.

Arrives at the lock driving Strahlungunterbre- the monitoring flag 21 is not up to its light beam 24 interrup ^¬ sponding position and holding this situation a certain time, the drive 8 in the opposite direction is angesteu ^¬ ert.

It is then, as in a manual removal control, the procedure described above performed in reverse order and the chip card driven back through the carriage 1 to the outside to be removed.

As shown in Figure 5, instead of the chip card 5, a chip cleaning card 33 is inserted into the carriage 1 and with the carriage 1 to the contact position and the locking member 18 of Verriegeiseinheit 32 moves in its Ver ^¬ locking position.

The width and the thickness of the chip cleaning card 33 entspre ^¬ chen the width and thickness of the IC card 5, while but the Chip cleaning card 33 has a smaller by a measure 38 Long as the smart card 5.

To this measurement chip 38, the cleaning card is thereby unit 32 33 displaceable between the abutment 39 and the locking member 18 in and against the import ^¬ direction at the locked lock.

For this purpose, an actuating tab 35 of smaller width than the width of the chip cleaning card 33 is arranged at the insertion slot-side end of the chip cleaning card 33, which protrudes outwardly through the open part 36 of the insertion slot 6 not covered by the locking part 18.

This actuating tab 35 can be grasped by an operator and the chip cleaning card 33 can be moved back and forth by the amount 38 in and against the direction of insertion 4.

On the surface of the chip cleaning card 33, a recessed cleaning pocket 37 is formed, in which a fluid cleaning agent can be arranged.

The cleaning case 37 covers at introduced chip cleaning ^¬ supply card 33 the area of the fixed contacts 31 so that these are covered by the cleaning agent at a reciprocating movement of the chip card 33 and cleaning ^¬ be gerei ^¬ nigt.
