[0012] In the drawings relating to the preferred exemplary embodiment, [0013] [0013]FIG. 1 shows a front view of a tachograph in which the receptacle according to the invention is installed, [0014] [0014]FIG. 2 shows a perspective view of the receptacle, [0015] [0015]FIG. 3 shows a side view of the receptacle viewed in the direction B in FIG. 2, a central region being recessed and the tension springs being ommitted from the illustration for the sake of clarity, [0016] [0016]FIG. 4 shows a partial sectional view of a front panel, of a printed circuit board and of the receptacle in an assignment provided in the tachograph according to FIG. 1. [0017] [0017]FIG. 5 is a perspective view of the locking latch.
[0018] The tachograph 1 illustrated in FIG. 1 has a front panel 2 which is connected to a parallelepiped-shaped installation housing and in which a display 3 is secured, and pushbutton keys 4 and 5 are arranged. 6 designates a window cutout assigned to the display 3; a cover 7, to which a lead seal 8 is assigned, closes off a plug mount provided for diagnostic and parameterization purposes. 9 and 10 designate slots which permit access to the receptacles and which are provided for personal data cards assigned to drivers I and II. The slots 9 and 10 are provided, for the sake of easier insertion of data cards, with funnel-shaped depressions 11 and 12 and with centrally formed finger grips 13 and 14 in such a way that the data cards can be inserted as far as the respective read/write position. A slot which is designated by 15 is provided for the print carrier of a printed record printer arranged in the tachograph 1 to pass through. Further pushbutton keys 16, 17 and 18 of the tachograph 1 which are guided in the front panel 2 and/or engage through the front wall are used, in combination with the pushbutton keys 4 and 5, to select the most important working time data of the drivers, to bring about forward and backward scrolling in the data records of a selected type of data, to initiate printing and to release the data cards. [0019] The receptacle 19 illustrated in FIG. 2 consists essentially of a cardholder 20 which forms a pocket for the data cards, a control slide 21 which is displaceably mounted on the cardholder 20, a locking latch 22 which is assigned to the control slide 21 and a closing element 23 which is rotatably mounted on the cardholder 20 and which has an operative connection to the control slide 21 by means of pins 25 or 26 via a connecting part 24 formed in the control slide 21. The receptacle 19 is, for the rest, configured in such a way that if two receptacles 19 are arranged one next to the other, as illustrated in FIG. 1, the control slides 21 and the locking latches 22 can be attached to the receptacle devices 19 on alternate sides in order to be able to arrange a release element which is, for example, motor-operated (not illustrated because it is not essential to the invention) and which, when a data card is released, pivots the locking latch 22 by interacting with a finger 27 (FIGS. 2 and 5) formed on the locking latch 22, in a fashion which serves the purpose, that is to say takes up as little space as possible in the tachograph 1. At this point it is also to be noted that the structural concept provided makes it easily possible to equip the receptacle 19 on both sides with ejection means, specifically with two control slides 21, tension springs 28 assigned thereto, two locking latches 22 and restoring springs 29 engaging thereon, the locking latches 22 having to be mechanically coupled to one another in order to permit the control slides 21 to be unlocked simultaneously. This ensures that even bent or curved data cards which cause increased friction in the guide grooves 30 and 31 of the cardholder 20 can be pushed forward into the release position without tilting. [0020] In particular, FIG. 2 shows that the cardholder 20 which is embodied in one piece as a punched and bent part has a reinforcing base element 32 which is provided, if appropriate with beading and on which ridges 33 and 34 are provided parallel to one another in such a way that the guide grooves 30, 31 which correspond essentially to the thickness of the data cards are formed between the ridges 33, 34 and the base element 32 and at the same time also serve to guide the data card laterally, specifically with little play. Tabs 35 and 36 are bent up from the base element 32 as end stops for the data cards which are to be pushed forward manually into the write/read position in the proposed receptacle 19. Slots 37 and 38 provided in the base element 32 are for drivers 39 formed on the control slides 21 to engage through. Tongues which extend from the ridges 33, 34 and are provided for guiding and securing the control slides 21 on the cardholder 20 are designated by 40 and 41, and 42 and 43, respectively. In this respect, keyhole-like guide slots 44 and 45 are formed in a control slide 21. Platforms 47, 48, 49 and 50 which are formed on the ridges 33, 34 and thus on the cardholder 20 and on which in each case centering pins 51, 52, 53 and 54 and threaded holes 55, 56, 57 and 58 are formed have the purpose of attaching the cardholder 20 to a printed circuit board 46 (FIG. 4) of the tachograph 1. In this context it is to be noted that in order to simplify the manufacture, it is possible merely to form supporting limbs, instead of platforms 47, 48, 49, 50, at right angles on the ridges 33, 34, said supporting limbs having lugs formed on them in order to form lacing connections to the printed circuit 46. Two bushings 59 to 60, which extend from the ridges 33, 34, serve as bearing axles for the locking latches 22. As is also apparent from FIG. 2, the base element 32 which is bent at the front has a centrally provided recess 61 and cutouts 64 and 65 which are assigned to the bolts 62 and 63 formed on the closing element 23. In addition, it is to be noted that hooks 66, 67, 68 and 69, on the one hand for the tension springs 28 to engage in, and on the other hand for the restoring springs 29 to engage in are also formed directly on the cardholder 20 which is preferably manufactured by means of a series connection tool. Apart from the driver 39, a retainer 71, which interacts with the locking latch 22, and a latching tooth 72 are formed on the one limb 70 of the control slide 21 which has an at least partially angled profile and is also manufactured from sheet metal as a punched and bent part and, as already mentioned, is displaceably guided on the cardholder 20. On the other limb 73, a hook 74 attached to the tension spring 28 is formed and the connecting part 24 controlling the closing element 23 is cut out. [0021] The closing element 23 is also manufactured by punching and bending techniques. The bolts 62, 63 already mentioned are formed on a bridge 75 which is constructed as a U profile and provided with bearing arms 76 and 77. At the latter, on the one hand the pins 25, 26 which engage in the connecting parts 24 of the control slides 21 and on the other hand the bearing journals 78 (FIG. 3) and 79 of the closing element 23 are pressed out. 80 and 81 designate bearing holes which are formed on the ridges 33, 34 and assigned to the bearing journals 78, 79 of the closing element 23 and are provided with arrows. One of the bearing holes is designated by 82 in FIG. 3. So that the closing element 23 can carry out its function, a retaining spring 83 which is directly connected to the closing element 23 and embodied as a leaf spring is provided. Said retaining spring 83 is formed essentially by a supporting element 84 which fits into the U profile of the bridge 75 of the closing element 23 and by pressing-on limbs 85 and 86 formed on said supporting element 84. The retaining spring 83 is attached to the closing element 23 in a positively locking fashion such that on the one hand eyelets 87 and 88 are formed in the retaining spring 83 and hooks 89 and 90 which are bent out of the closing element 23 are assigned to said eyelets 87 and 88, while on the other hand slots are formed in the limb (not designated in more detail) of the bridge 75 and tongues assigned to the slots are formed on the supporting element 84 of the retaining spring 83. The tongue-slot connections are designated by 91 and 92 in FIG. 2. [0022] As can be additionally inferred from FIG. 2, and in particular from FIG. 3, a stop 93 or 94 which is effective in the axial direction and is formed by punching and bending techniques is assigned to the locking latch 22, said stop being supplemented in its effect, when the locking latch 22 is pivoted by means of the latching tooth 72 formed on the control slide 21, by the retainer 71 which lies over the locking latch 22 in this functional state. 95 and 96 designate areas which are formed on the rear of the bolts 62, 63 and are essentially at right angles to the plane of movement of the data cards in the mounted state of the closing element 23, that is to say they are dipped into the plane of movement of the data cards under the action of the retaining spring 83 and form a locking plane. In contrast, front areas 97 and 98 of the bolts 62, 63, which are inclined with respect to the plane of movement of the data cards, form an oblique plane which facilitates the pivoting of the closing element 23 when the data cards are inserted. [0023] The dimension “a” given in FIG. 3 is used to label the height of the guide grooves 30, 31 provided between the base element 32 and the ridges 33, 34. In FIG. 3, the section of the connecting part 24 which permits the closing element 23 to pivot out of the illustrated closed position is designated by 24 a. The section of the connecting part 24 which causes the bolts 62, 63 to be raised during the insertion or outputting of a data card in order to unlock the cardholder 20 is designated by 24 b. The section 24 c prevents a rotary movement of the closing element 23 out of the closed position when the control slide 21 is arrested by means of the locking latch 22, owing to the connecting part boundary 99 which runs obliquely with respect to the direction of movement of the control slide 21. In other words, the bolts 62, 63 are prevented from being raised from the outside. [0024] For the sake of completeness it is to be noted that the limb 70 of the control slide 21 has suitable cutouts to enable the connecting part 24 to move and to form the connecting part 24 with a very low overall height. The cutout illustrated by dotted lines in FIG. 3 is designated by 100. [0025] [0025]FIG. 4 which shows the assignment of the receptacle 19 according to the invention to the front panel 2 and to the printed circuit board 46 of the tachograph 1 illustrates the relatively small overall height requirement of the receptacle 19. That is to say, in the specific case of the tachograph 1, there is an overall height of a maximum 10 mm available between the printed circuit board 46 and a base part 101. The receptacle 19 which is attached to the printed circuit board 46 by means of screws, of which one is designated by 102, permits, with an overall height of approximately 7.5 mm, a relatively thin and large-area base part 101 to yield when the tachograph 1 is handled, for example when it is installed in a vehicle, without affecting the receptacle 19, and via the latter the printed circuit board 46 which is sensitive to bending. The side wall of the tachograph 1 is designated by 103 and 104 is a data card which is to be inserted. [0026] The locking latch 22 which can be seen only partially in the figures already described interacts with the control slide 21 is shown in FIG. 5. The locking latch 22 constitutes essentially a two-armed lever, one arm of which is formed by the finger 27 which is actuated in order to release or reject a data card in the direction of the arrow P. The other arm is provided with a latch tip 105 which interacts with the latching tooth 72 formed on the control slide 21. A raised hook 106 is used to engage one end of the restoring spring 29; a bearing hole, corresponding to the bushings 59, 60, on the locking latch 22 is designated by 107. The sequence when a data card 104 is inserted and output will be summarized once more below. When a data card 104 is inserted, it is initially pre-aligned in one of the slots 9 or 10 in the front panel 2, strikes against the areas 97, 98 formed on the bolts 62, 63 and pivots, owing to the given arrangement of the closing element 23 in the manner of a wedge mechanism, the pressing-on limbs 85, 86 of the retaining spring 83 experiencing additional prestress. The data card 104 is subsequently oriented and retained by the guide grooves 30, 31 and the pressing-on limbs 85, 86 of the retaining spring 83. As the data card 104 is inserted further, it strikes against the driver 39 which is formed on the control slide 21 and engages in the guide groove 30, as a result of which the control slide 21 is pushed counter to the force of the tension spring 28, specifically until the data card 104 abuts against the tab 35, 36 or until the latch tip 105 of the locking latch 22 drops in in front of the latching tooth 72 formed on the control slide 21. Directly before the data card 104 has reached the read/write position as a result of the activation of the locking latch 22, the closing element 23 has been pivoted by means of the connecting part 24, and the bolts 62, 63 have been lowered behind the inserted data card 104. The reaching of the read/write position, in other words the correct functioning position of the data card 104 can be monitored, for example, by means of a photoelectric barrier assigned to the locking latch 22. The outputting of the data card 104 is triggered by activating a pushbutton key and is carried out by pivoting the locking latch 22 by virtue of the fact that a preferably motor-activated release element engages on the finger 27. After the control slide 21 has been released by the locking latch 22, the tension spring 28 guides the control slide 21 back into the initial position predefined by the connecting part 24. In the process, the bolts 62, 63 are raised directly after the release, under the control of the connecting part 24. At the same time as the control slide 21 is guided back, the data card 104 is pushed into the release position, the pressing-on limbs 85, 86 of the retaining spring 83 performing a braking function. If the data card 104 is removed, the closing element 23 also pivots, under the effect of the retaining spring 83, back into the initial position, also determined by the connecting part 24, in which position the bolts 62, 63 engage in the plane of movement of the data cards 104, as shown by FIG. 4.
