The invention relates to a new decimal point printing device in calculating machines with a numeric keypad for printing one below the other, comma below comma, of different amounts Number of value places to the right of the decimal point and with one the decimal point of the amount in the trolley defining comma setting means as well as a cooperative, the movement of the Actuating pin carriage optionally limiting and determining the comma print position in the printing unit Position setting means and aims to display amounts with different numbers of digits to the right of the decimal point below one another in the same comma position to automatically print without it being necessary to print the Places to the right of the comma may have to be filled in by keying in zeros, and furthermore in the case of a product of two factors, the resulting decimal fraction in full and in the same position of the comma in a simple way.

This is achieved in that, according to the invention, the setting means on the one hand with a step stop that can be adjusted transversely to the positioning pin carriage and, on the other hand, via an adjustment rail is connected to a transverse to the comma or point type carrier movable locking plate, which the latter in their displacement caused by the setting of the position adjusting means the corresponding Comma-point type carrier releases.

It was known that individual adjacently positioned adjusting elements were used as setting means for the decimal point to be provided, each of which by special connecting rods each with an adjustable stop is connected and works together with a number of comma pins.

The construction is simplified by using a swiveling stepped stop. she also offers the option of not only the decimal point but also the three-way spacing To print decimal points in the relevant positions.

For multiplying machines with the expression of the multiplier and the multiplicand without consideration on the number of digits to the right of the decimal point in the corresponding decimal point for the printout of the product, according to the invention, the locking plate is doubled by the comma print Number of digits The number of digits set by the digit setting means to the right of the decimal point automatically changed.

For this purpose, according to the invention, the locking plate for the comma and point type levers is used in calculating machines before the product is printed by a comma printing device

The calculating machine on which the invention is to be explained has a keypad with a Ten key set 1 (Fig. 1) with the number keys »1« to "9" and a zero key bar as well as an operation key on the right side of the ten key set for adding 2, subtracting 3, not printing 4, sub-totaling 5, totaling 6 and repeating 7.

On the left side there are two operation keys for multiplication, namely a multiplier key 8 (X) for triggering the first machine gear of the multiplication after the first factor (multiplier) has been introduced into the key set, and a multiplicand key 9 (=) for triggering the second measure

machine gear after the second factor (multiplicand) has been keyed in.

The calculating machine construction used here is connected to the second machine aisle automatically the multiplication between the two factors, and when this is finished, takes place automatically printing the formed product. The operation key 9 is followed by a downward Correction key 11 and this a comma key 12, which will be discussed further below.

The keys mentioned up to this point are grouped together by a key frame 13. To the left of the Key frame is a setting lever 14 is provided, the setting of the decimal point in the print, so the number of places to the right of the decimal point is determined by the lever in its topmost setting the imprint of the comma to the left of the third digit from the right of the amount and in the following setting to the left of the second digit from the right. In the lowest Position of the setting lever 14 there is no comma print.

The machine's counter is concealed. Through a window 15 (FIG. 1) above the Housing a position indicator 16 is visible, which indicates the respective position of the actuator pin carriage. By The paper strip 18 passes through a cutout 17 of the housing. The amount type segments also protrude into it 19 into it. To the right of each amount type segment, a comma type lever 21 or a point type lever 22 is provided.

The adjusting pin carriage which can be moved transversely below the key frame 13 on transverse rods 23 (FIG. 4) 24 is activated by a tension spring 25 (FIG. 6) each time one of the keys of the ten-key set is depressed by means of a locking mechanism 26 which cooperates with a toothing 20 (FIG. 3) of the adjusting pin carriage, Moved in a known manner step by step to the left and at the end of the machine aisle moved back into its rest position by a linkage 27 (FIG. 6) moved by the machine drive.

The adjusting pin carriage carries vertical rows of adjusting pins 28 (F i g. 3, 6), which gradually over the along the machine adjustable switching members 29 (Fig. 6) are moved. The by pressing the Buttons 1 downwardly displaced adjusting pins 28 limit the movement of the spring-influenced switching elements 29 when they are released upwards. According to the movement of the switching elements while the machine is running, the wheels of the counter 31 are switched on, and on the same The type segments 19 connected to the switching elements 29 are set.

The amount type segments 19 (FIG. 5) are mounted by means of pins 32 on rocker arms 33, which in turn are arranged pivotably about a fixed axis 34. They are individually under the effect of springs, not shown, which act on lower extensions 35 and turn them clockwise try to turn. They are usually well known and therefore not described in detail Locking devices 36 in the FIG. 5 shown rest position held in which the setting of the type segments 19, which are temporarily connected to the associated switching elements 29 (Fig. 6) are connected to the digits to be printed. If the rocker arm 33 (Fig. 5) triggered at a given time, they hit the paper strip and with the set number type print the amount in question.

The comma type levers 21, which have a comma type 37 at the rear end, are also on of the axis 34 pivotably mounted and have downwardly protruding extensions 38 on which clamping, feathers 39 attack. Triggering a comma type lever for printing is off the trigger of the type segment to the left of it

ίο 19 depends on what is known per se.

In order to trigger only that comma type lever 21 which the means of the Adjustment lever 14 (FIG. 1) corresponds to the set comma position, the following connection is between the setting lever 14 and the comma type levers 21 are provided:

The setting lever 14 (Fig. 6) is on a pin 41 of the left side wall 42 of the machine, which is united by cross bars 43 with the right side wall 44 to form a machine frame, pivotably mounted. At its lower end it carries a pin 45 (Fig. 4), which with a by means of a spring 46 loaded locking lever 47 cooperates, namely by means of three notches 48, which hold the setting lever 14 resiliently in its three setting positions. By means of the pin 45 is an adjusting rail 49 is also articulated to the position adjusting lever 14, which at the lower end (Fig. 6) is connected by means of a pin 51 to a stop lever 52 which is pivotable on a pin 53 is stored. The pin 53 sits on a bracket 54 mounted on the side wall 42.

At the upper end (Fig. 6, 7) the adjusting rail 49 is connected to an angle lever by means of a pin 55 56 connected, which is mounted on a pin 57 on a bracket 58 of the left Side wall 42 is attached. The upper end 59 (F i g. 6, 7) of the angle lever 56 works with a Pin 61 of a locking plate 62 together.

The locking plate 62, the shape of which can be seen more clearly from FIG. 7, is attached by means of slots 63 Pins 64 mounted so as to be displaceable transversely. The pins are carried on one of the side walls 42,44 Bridge 65 attached. Between a pin 66 of the locking plate 62 and a pin 67 of the lever 56 is a Spring 68 tensioned, which the locking plate 62 on the pin 61 with the upper end of the arm 59 of the Seeks to keep lever 56 in place. When pivoting the angle lever 56 in one or the other in the other direction by moving the adjusting rail 49 up and down, the locking plate 62 becomes corresponding adjusted to the right or left. The locking plate has on its upper edge (Fig. 7) a series of incisions 71, which with the extensions 38 (FIG. 5) of the comma type lever 21 work together.

If the upper edge of the locking plate 62 (FIG. 7) is in front of the extension 38 of a comma type lever 21, so this is blocked and cannot despite the triggering of its type segment located to the left of it get to the imprint. If, on the other hand, there is a notch 71 opposite a comma type lever, then so this is triggered when its type segment is triggered.

When adjusting the locking plate 62 according to FIG. 7, the one is to the right of the fourth type segment lever 19 comma type levers 33 arranged from the right are released through an incision 71,

It must be taken along and the locking of the lever 101 (Fig. 6) to ensure that the number of digits to the right of the is canceled. As a result, the pawl 96 is moved after the decimal point in the product equal to the sum of the number on the left and thereby enters the tooth incision 98 in the machine 50 in the relevant places in front of it and takes the locking factors. This number is plate 62 to the left with. The movement of the pawl six, since a digit is added 96 to the second factor, is thereby made by means of the setting lever. 14 with the stepped stop 93, 94 set.

In order to now correspond to the comma position in the product, the setting lever 14 is to the right in three places

To correct, the following device has been made: 55 set from the decimal point, so the locking plate is off. The adjustment rail 49 (Fig. 6) has already been extended upwards by three places after pin 55 beyond its starting position and moved on the left. From this position, the end is provided with a stepped stop in the form of two stop surfaces 93, 94 when the pawl 96 engages by a further three points, with which the stop surfaces 93, 94 move to the left until the bent end 95 on the left bent end 95 of a driving pawl 96 60 the preset stop surface 93 hits. If teeth 98 on the lower edge of the locking plate 62 were working together, which are set to the middle position by a lug 97 with the adjusting lever, the locking plate 62 would cooperate before the pawl engages (see also FIG. 7). The pawl 96 96, one position further to the right, is in position by means of pin 99 on an angle lever 101 , and from this position it would be steered, the one on the already mentioned pin 57 65 two positions to the left until it stops is stored. The pawl is moved with a pin 102 of the pawl against the stop surface 94, on an attachment surface 103 of the lever 101 , when the angle lever 101 is pivoted in the counterclockwise direction of the action of a between the pin 102 and.

It can be seen from this that the locking plate 62 is moved to the left by twice the setting of the position setting lever 14 when the sum is drawn, so that the sum printed out correctly receives twice the number of positions to the right of the decimal point as one of the factors.

The counterclockwise lever 101 and the pawl 96 adjusted to the left are reset by the cam 114 (FIG. 5) via the roller lever 112 after the total imprint has been carried out, so that these parts are again available for carrying out a new total imprint.

When the position setting lever 14 is moved to its lowest position (Fig. 1), the locking plate 62 is returned to the right via the setting rail 49 (Fig. 6) and the angle lever 56, with the incisions 71 getting outside the path of the comma type lever 21, see above that thereby the printing of the comma and the decimal points is completely prevented.

It does not need any special explanation that the two step stops 77, 78 and 93, 94 with any more than two stop surfaces can be equipped when it comes down to the adjustable To extend the decimal point over further numbers of digits to the right of the decimal point.
