The task of the slot is ₅ each: ^r only let one card or a certain number of cards pass at the same time. It seems plausible: endV: d3.ß "- this.

The funding consists, for example, of a driven one.

The end of the recording medium has reached its lowest position, in which it rests on the lower roller, the upper roller is moved again over the lower one, so that the recording medium is enclosed between the two rollers, 'by which it is then pulled out from under the stack and into a guideway is entered. _

The card magazine 1, which is in your in Pig. 1 is designed for cards of different lengths, has only 'one end wall 3, on which the stack of cards 4 is aligned. The Eoden 2 of the card magazine 1 has an opening 7 extending from the front wall 3 and extending over the entire width of the magazine ΐ or the stack of cards 4 contained therein. stretches. This opening 7 should be approximately square, for example. In the Pail shown, the opening 7 is largely covered by an elastic tongue 13 flush with the top of the magazine bottom 2, but at most to the extent that an approximately 1 to 2 centimeter wide strip of cards protrudes. On the underside of the tongue 13, near its free end, a peeling organ is arranged in the form of a suction capsule 5, above which the tongue 13 has one or more perforations, so that at this point a card 6 is placed on it If punched cards are used, the perforations 20 are arranged in such a way that they in no way coincide with the perforations of the cards, taking into account their perforations, which could make it impossible to create the required negative pressure in the suction capsule 5 A flap can also take the place of a tongue 13 or

In general, however, there is a special one in this particular case Ventilation device of the suction capsule can be dispensed with at all, since the generation of negative pressure ends at the end of the downward stroke and the already small vacuum achieved is likely to be quickly lost due to the leakage.

When the piston rod 22 moves up and down, the bellows 21 is primarily compressed and pulled apart, which thus temporarily generates a negative pressure. The suction capsol 5 itself is connected to the piston rod in the example shown 22 after the lower of the disks 23 used to clamp the bellows 21 on the ends of the suction capsule 5 has come to a concern or-but, at least beforehand partly through the enclosed air cushion.
