^{2> da} "The invention relates to a punch card reader of the type described in the preamble of claim 1.

Such card readers are generally referred to as static card readers and are thereby distinguished from dynamic card readers in which a single row of contacts scans rows of bit positions by causing a relative movement between the card and the contacts. In the case of static card readers, when an abiast member makes contact with the associated contact, a sliding movement is desired in order to prevent inadequate electrical contact. Such poor electrical contact can be caused by small particles of the card material, for example small fibers, which are detached from the card when the card is inserted or which protrude from the edge of a poorly formed hole across the surface of the hole. A serious problem a ₅ represent '' ng of foreign bodies - In general, the amount of debris is very small, but a card reader for ^{vieIe thousands of} reads, when using the ^ Ansamm

^{In a} known hole card reader of one Z & ™ ß ^{date set out type (br} "- ^che Patent 1,014,900) is that the card overall at an angle, the grinding movement brought about in such a way

against the scanning block that encompasses the scanning elements, the scanning ^{elements sliding} along the surface of the force even before they enter the corresponding holes. This carries the risk of increased wear and tear on the card as well

a deposit of scraped-off map parts on ^the contact surfaces with itself. The ^{grinding front} ß ^on S &<* ™ * only covers a certain part of ^the mating contact, so that this TeU is subject to relatively heavy wear.

In order to read the card 3 ν, it is placed in the card ments which the recesses 19 of the receiving slot 5 are inserted so that a latching member penetrates the support plate 17. The frame 14 includes 106 is actuated. As a result, a drive mechanism is formed, furthermore two lower flanges 18, which are triggered at a distance from the mechanism which the card 3 is arranged transversely to its width, so that one side moves, specifically with the aid of a pressure depression 20 in a flat vertical plate 40, so that the card on a scanning arrangement len surface 22 ends. This serves as a stop surface for individual self-supporting scanning elements 164, which grips the displacement of the moving parts. The scanning takes place in such a way that the reading device 10 is limited to the right.
Parts of the sensing members 164 through holes in the 40. In the lower part of the flanges 18 are horizontal card 3 and thereby the presence of slots 24 are arranged, one of which is located between these holes and causes an electrical flanges to be located Control slide 90 is carried in a tric circuit between parts of the scanning elements of a horizontal position. The frame, which and parts of contacts 132 are closed, 14 has two further projecting flanges 26 which are arranged separately from the card and which do not come into contact with each other with 45 opposite to the flanges 16 and IS of this. There is provided a plate 124 consisting of flanges of insulating material extending out and arranged to receive 50 of the pressure plate 40 therebetween, with recesses 130 formed therein. These flanges 50 are on either side of the compression mold and assembly to which the bit position display plate 40 is arranged in the area of the flanges 26, and the holes of the card 3 correspond.
