DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention proceeds from a Chip card reading apparatus according to the preamble of claim 1. In the known chip card readings of this type, actuation is accomplished in that the chip card is inserted into the slide and inserted with it, possibly against the force of a spring being tensioned, until reaching a final position defined by a stop, in which the card, with simultaneous operation of a limit switch, is brought into it read position and held in place there. Removal takes place by a reverse process by releasing the lock holding the card in its final position, whereupon it is automatically ejected under the force of the tensioned spring. In these apparatuses, employed, for instance, for protection against or prevention of theft of automobile radios, the slide generally consists of transparent material, the slide being provided with a signal unit, for instance, a light-emitting diode shining on the slide, which becomes effective in the extended position.
The known chip card readings have proven themselves well in practice, but in many cases have a constructive height making their use difficult or occasionally, even ruling it out.
SUMMARY OF THE INVENTION
The objective of the present invention is accordingly the creation of a chip card reading apparatus permitting the exertion of an optical signal effect and which make economical production possible. This problem is solved by a Chip card reading apparatus with the characteristics reproduced in claim 1.
With the invention, a chip card reading apparatus is created in which the lower part, generally serving as the housing lid, simultaneously serves as the slide permitting the introduction of the chip card and which can be constructed in this way with an extraordinary small constructive height. Beyond that the frame is of simple design and can therefore be economically manufactured, in view of the fact that it consists of only two parts that con be connected by simply pushing them together, and also in view of the fact that the housing consists of different materials because of the transparency of the slide. It therefore permits a selection of materials optimally adapted to the other requirements, for instance, the required guidance characteristics.
BRIEF DESCRIPTION OF THE DRAWING FIGURES
Additionally details of the invention characterized in the claims are explained below on the basis of the attached drawings. These show, in

FIG. 2, the housing reproduced in FIG. 1 in the read position;
FIG. 3, a view from below onto the housing reproduced in FIG. 1;
FIG. 4, a view of another embodiment of a contact support frame; and
FIG. 5, a view from the side onto FIG. 4.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The chip card reading apparatus reproduced in FIGS. 1-3 consists of a housing constructed in two parts having a lower part 1 (hereinafter slide 1) and an upper part 23 intended for attachment to a circuit board. In case of this embodiment, the contacts 4 are clipped into the upper housing part together with the (3) contact support and are thus an integral component of the upper housing part 2. The contacts 4 are each connected via a limit switch 20 to a contact lead, not shown in the drawing. The lower frame part 1 is constructed as a slide that permits the introduction of the chip card into the apparatus and is guided on the upper frame part 2 such that it can be displaced between two engaged positions, of which one engaged position defines the insertion or removal position and the other engaged position the read position for the chip card.
For this purpose, the upper frame part 2 is provided on each side with a rail 7 as a guide and the lower frame part 1 with a carriage 8 in the form of a grooved bar encompassing the guide rail 7, opening in its middle area like a window and, because of its window like opening 13, forming an elastic ridge 123, on which a catch tab 9 is formed. Two catches 10 and 11 are formed in the upp
