Reader for data carrier

Field of application of the invention

The proposed mechanical device relates to a reading device for data carriers, in particular for recording production data, for passport checks or the like.

Object of the invention

The object of the invention is to provide a device which makes it possible to read both a hole identification card and an identification card by means of simple operation and that a card inserted in the device is not ejected until it is completely read.

Characteristic of the known technical solutions

In the patent application no. 1774994 a solution is described in which the guide device for punched cards is formed by a vertically aligned chute through which the punched cards fall freely under the influence of gravity.

A disadvantage of this device is that the user after inserting a punched card in the guide device the same again after reading and the case through the shaft, just at the opposite point of the throw by hand must · This means a two-time touch the card and the Related time delay, Another disadvantage was that sticking moisture in a card or other pollution same.in the chute. In this case, a postpone the card is required.

In the leaflet ITr. 1279391 a device is described, with v / elcher also information carrier (punched cards) are read. Here, the inserted card is read by the operation of an additional button and then ejected again. -

The disadvantage of this device that the same is provided with an enormously high design effort. Furthermore, an additional actuating device is required by the control knob.

A punch card reader is also described in DAS 1549-75.

In this device, a Ausschubvorrichtung is stretched by the inserted punched card and released after reading by the drop of an electromagnet.

The disadvantage is-here the design effort in general and for the Ausschub der.Karte still provided an additional solenoid, which also requires an additional voltage.

Furthermore , ID card readers have become known that only one? Card slot and a read block. The operator inserts the card or card into the insertion slot as far as it will go and pulls it out again. This simple device is only for badges that are partially perforated, but not for over the entire length perforated identification cards used here »There is a risk that a card from the operator has not been fully inserted to the stop, which information loss durch.nicht complete detection of the reading process.

Explanation of the essence of the invention

The invention has for its object to provide a device that can read with simple mechanical means both ID cards and over the entire length described data carrier, in particular hole cards. The inserted data carrier should only be released again when all information entered on the data carrier has been sensed.

According to the invention this is achieved in that during the insertion of a data carrier, a slider and a pivotable lever ¹ in conjunction with a pair of pawls causes a clamping operation and thereby prevents premature ejection of the data carrier. The data carrier is only released by the slider and the pawl pair when all information entered on the data carrier has been sensed.

Embodiment:

The invention will be described below with reference to drawings. In this show:

228835

Fig. 1 is a perspective view of the Einriphtung seen from the left front;

2 shows a partial section of the functional parts in plan view, wherein the data carrier is inserted halfway;

Fig. 3 is a partial section of the functional parts in the. Top view, wherein the disk is inserted to the stop.

The device consists of two guide plates 1, 2 and two intermediate plates 3 "which are firmly connected to each other by screws 5. An indicated cladding sheet 4 is screwed to the guide plates 1, 2. In the guide plates 1, 2 there is a DurchbruGh 7, through which the sensing process of the data carrier takes place. In the upper guide plate 1 there is a recess 6 and in the lower guide plate 2, a longitudinal groove 8, in which a slider 9 is able to slide. On the slider 9 are each paragraphs 10, 1t, which in turn are able to cooperate with a pair of pawls 20, 21. The two pawls 20, 21 are pivotally mounted on bolts 22, 23 and are held by means of a tension spring 24 in its initial position * A lever 15 is pivotally mounted on a bolt 16. This lever 15 abuts one end 14 of the slider 9 and is in constant communication with the same. A cover plate 27 serves both to guide the slider 9, the pawls 20, 21 and to ensure a concurrent longitudinal groove. 8

Mode of action of the device;

If a reading or reading is to take place on the basis of data carriers, then the data carrier D is moved by hand through the

228835

serving in the direction of arrow a'Fig. 1 / inserted between the two guide plates 1, 2. The information 28 present in the data card D is sensed during insertion.

For this purpose, the opening 7 is provided for receiving the read block.

The disk D, which comes to a stop 13 of the slider 9 to the plant, pushes the latter in the longitudinal groove 8 against the feebelelastenden lever 15 in the direction of arrow a. until the position of Fig. 3 is reached. The two pawls 20 ", 21 v / earth at the beginning of the insertion process by the paragraphs 11 so far in the insertion direction about the bolts 22, 23 against the tension spring 24 is rotated until the ends 25, 26 come to slide on the parallel part 29 of the slider 9 The pawls 20, 21 slide with their ends 25, 26 along the slide 9 until they reach the shoulders 10 of the slider 9. At this narrowed point of the slide 9, the two pawls 20, 21 pivot as a result of spring tension 24 FIG in such a way that the slide 9 can be pulled forward under the course of the tensioned lever 15 against the direction of the arrow A. In this case also the data carrier D resting against the stop 13 of the slide 9 is pushed forwards against the direction of the arrow a and the operator If, for example, the operator does not make an exact or complete insertion when inserting a data card, then complete readings d he made in the disk information applied. Misinformation would be the result here. Such a situation is evident from FIG. The disk D is here by the operator only, as shown in Fig. 2'ersichtlich, has been inserted up to half. The two pawls 20, 21 hold with their ends 25, 26 Lind the course of the spring 24, the slider 9, so that the lever 15 with its acting tension spring 18 is not the

228835

Strength to overcome the two pawls to push the disk forward. Rather, the two pawls 20, 21 are jammed on the slide 9 so that the lever 15 with its spring 18 can not overcome this jammed slide 9.

For the operator, this is the sign that no exact or complete reading has taken place. Rather, it is forced to insert the data carrier even further until the slider 9 has assumed the position shown in FIG. Only in this position, the two pawls 2C, 21 can swing as a result of paragraphs 10 of the slider 9 and the lever 15 vd.rd push the slider 9 forward as a result of-tensioned spring 18 and thus eject the voltage applied to the slider 9 data carrier.
