Advantageous embodiments and further developments of the subject matter of the invention are specified in the subclaims.

The invention is explained in more detail below using embodiments shown in the drawing.

Figure 1 shows the control unit in principle. Figure 2 shows the entire housing structure in an exploded view.

Figure 3 shows the rear part of the cover 3 seen from below.

Such a car radio telephone consists of a handset HA which can be placed on an upper part 3 with corresponding recesses 31 and 32 in it. This holder or upper part 31 can in principle be folded about a hinge 10. For this purpose, the upper part 3 is connected to a tub-shaped lower part 1 via this hinge 10. To insert the identity card 15, which is required to operate the telephone and is a magnetic card, the two parts 3 and 1 are designed to be pivotable against each other. In the locked state, ie when part 1 is folded onto part 2, the identity card is inaccessible and the car telephone is ready for use. The two arrows indicate the folding direction and the insertion direction of the identity card.

In detail, the receiving part for the handset consists of a base part 1, which has a hinge part 10 on one side and a kind of cover 1a on the other side. This base part can be screwed to the vehicle. The upper part 3, which is designed as a cover, can be placed on this hinge part 10. For this purpose, the hinge part 10 has grooves 11, into which the spring-like projections 12 shown in Fig. 3 fit in the

_ 3 - VPA 85 P 1 5 9 3 EN

can be inserted inside the upper part 3. In the illustration according to Fig. 2, the hinge is shown in the locked state, i.e. in the state in which the cover 3 is opened onto the part 1. The springs 33 in the hinge part ensure that when the upper part 3 is unlocked, the entire upper part is pressed upwards at an angle.

The upper part is locked by means of hinge-like handles 20 which have lips 21 on the inside, which finally engage in corresponding groove-shaped recesses 22 in the base part 1 when folded down. If, after engaging, the outer surfaces of the handles are pressed, the engagement is released and the part is pressed upwards by the springs 33.

The electrical equipment of the card reader is located inside the upper part 3. For this purpose, a type of base chassis is provided, consisting of the middle part 2, onto which a card reader 4 and an additional board 5 are arranged in a way that can be plugged and snapped on. The base chassis 2 is locked into the egg-shaped upper part 3, and this is done on the one hand by means of nose-shaped projections 18, which can first be inserted into corresponding insertion openings 19 in the upper part, after which the middle part together with its fork-shaped extensions 13 can be swiveled into the upper part 3. It can then be connected to these by screw connections (not shown). The fork-shaped extensions 13 engage in corresponding recesses 14 in the upper part according to Fig. 3.

The additional board 5 has a light-emitting diode 8, which serves as a kind of standby indicator. For this purpose, light exit openings 9 are provided in the cover 3. The scattered light shows that the system is in operation even when the handset is on the hook and at night*.

- « - VPA 85 P 1 5 9 3 EN

Furthermore, openings 29 are provided in the upper part through which sound can emerge from the receiver of the handset HA, for which a recess 32 is provided there, even when the handset is on the hook.

To dampen the noise when placing the handset HA on the upper part, rubber buffers are provided in both recess 31 and recess 32 for the headset.

In order to be able to recognize the slot 16 for the identity card 15 even at night, the crystal-clear base 6 of the card reader is illuminated by a lamp on the additional board. When opened, the slot can therefore be seen very clearly, which also has an identification mark 17 for the correct position of the identity card 15. The crystal-clear material of the base of the card reader acts as a type of light guide, so that the last-mentioned effect is achieved.

The card reader board 40, which carries the main electrical functions, can be connected to the mating connectors 38 on the additional board via a plug part 39. All other required connecting cables, namely the cable to the radio 35 and the cable 25 to the handset HA, can be plugged into the additional board. For this purpose, a socket strip 24 is used for the cable 25, which can be plugged onto the plug strip 23 on the additional board. The cable 25 is led out of the top part at the side, through a pivoting connection part 26. This connection part 26 has a plug and screw socket 27, which is led to the handset in multiple poles, which also contains the touch keyboard and all other operating functions. The pivoting is therefore provided in order to connect the cable to

- 5 - VPA 85 P 1 5 9 3 EN

to protect this end and to facilitate screwing. A stop 26a in the upper part 3 ensures that the rotation is limited.

The main connection cable to the radio 35 has a plug
37 and is led out through the recess 34 in the middle part 2 and finally through an opening 36 in the lower part to the outside. As indicated, the
