Description

GERMAN

In counting card controlled machines such as in punched card machines., it is common to use the tabulation lists on which the information on the punched cards written down by a printing unit are, by a line switching device in certain Way to give a feed. After each card has been printed, a single-line advance takes place; When changing card groups, a multi-cell feed can take place.

According to the invention, the line switch device now issued under the supervision of the group control facility a larger advance of the list before the last card in a group is printed than with the same line-by-line feeds before the printing of the previous cards the group. This can be referred to as the feed for the »last line spacing«.

In a manner known per se, you can of course also choose between the last item; a group and the first item of the next group, special distance, the "group distance", can be done by placing between these two items are also fed a larger feed than the regular line spacing between the items assigned to the individual cards.

While in the known way of working only the individual item groups, on the list by larger ones Distances are separated from each other, according to the invention, the last card of the group of the other cards in the group are withdrawn. In addition, of course, the group distance feed can also be used take place. This way of working makes it possible to mix sum cards between the item cards and the Then write down the cards in an ordinary table printer (without adding units). The last cards each group are in this case always sum cards, and it is made by the specified measure achieves that the sum clearly stands out from the corresponding items in a group.

In the drawing, an embodiment of the invention for constant additional feed is schematically illustrated.

Item cards with the associated sum card. In the latter case the cards would be ^{sorted 1} so that the sum card is always at the end of a group.

The end of a group of cards is determined by a group control device, which in turn controls a step circuit which, depending on the hand setting, results in a typeface as shown in Figs. 1, 2 and. 3 is shown. Fig. 1 shows a list in which the group control does not affect the Has stepping. The cards are written off continuously here, regardless of whether the Group number changes or not. This case occurs when z. B. only written off sum cards between which there are no control cards. Fig. 2 shows a list in which the group control activates two spaces after the end of the group and printing the details of the last cards, It does not matter whether there is a sum card at the end of the group or not. For the list after Fig. 3, the machine according to the invention is designed so that the group control before the information is printed the last card switches on one space and after printing two spaces. This step-by-step is particularly advantageous if the associated sum card is at the end of a card group is located. This makes the total special compared to the other items in the list is highlighted.

The circuit diagram from which the control for the paper feed and the group control can be seen is shown in FIG. 4. For the sake of clarity, the circuit was only shown for one column, while in reality all columns of a card at the same time

and the positions are sensed one after the other. Switching elements that occur more often and to each other are connected in parallel are indicated by the distribution connections.

The cards are sensed by brushes b ¹ and b ^2. They conduct the current to the group control relay G. Furthermore, current is conducted from the brushes b ² to the printing unit magnets D , which set the printing unit according to the perforations in the card.

The group control relays are designed as differential relays. They have two windings that magnetically cancel each other out when excited. The relay only responds when current flows through one of the two windings, but not when it flows through both windings at the same time. If the group numbers of the two cards are the same, current flows through both windings of the group control relay G so that it does not respond.

If the group numbers in the two cards are not the same, current only flows through one winding in certain group control relays, so that they respond briefly and close their contact g. At the contacts g a locking lever 10 is provided, which also keeps the contact g closed after the relays G are de-energized again. Only after the end of a card game is the locking lever 10 raised by a cam control so that the contact g can open. If one of the contacts g is closed, the magnet M can receive current for the line circuit via the switch P (the switching positions of which will be explained below), the cam contacts n ¹ or Ji ² and the contact g. The effect of the magnet M will be returned to later.

If the switch P is in the middle position, the circuit remains interrupted, even if one of the contacts g closes. In this case, the group control has no effect on the step switching by the magnet M (list diagram Fig. 1).

If the switch P is switched down, the circuit is briefly closed twice in succession ^{by the cam contact w 2} , so that the magnet M is excited twice and the list is thereby switched forward by two steps. The shape and position of the cam for the contact w ² was chosen so that it only closes its contact twice after the card has been printed (list picture Fig. 2). The cam is on a shaft that rotates once per deck of cards.

If the switch P is switched to the upper position, the circuit to the magnet M is closed by the cam contact n ¹ and the cam contact n ² . The cam contact n ¹ is controlled by a cam which closes the contact once per game of cards. The shape and position of the cam are chosen so that it closes before printing. The magnet M is excited before printing and the list is switched one step further. Since the circuit is now ^{closed via the cam contact η 2} , the magnet M is excited twice more after printing. There are thus one step before printing and two steps after it, which corresponds to the list image according to FIG. 3. A list image with different distances compared to FIGS. 2 and 3 is possible by giving the cams for the contacts n ¹ and Φ -different shapes, or by providing several cam contacts that are connected to the circuit by means of several switches similar to the switch P the magnet M are switched. Furthermore it is also without
