The invention relates to the selectable setting of a place-limited value imprint for office machines and data processing systems of a mechanical or electromechanical type with product, ZShI, input and storage units using a pulse-controlled relay chain step mechanism.

Known devices in mechanical or electromechanical office machines read the values to be printed out from the individual works with the help of a rotating cam roller, with As the reading capacity increases, the cam roller becomes quite large and difficult to manufacture Can only a limited number of cams be attached to the circumference of the fold? One after the other contacts, which in turn close currents for working magnets, through which he printing is in progress. These facilities have the disadvantage that the reading capacity and the reading speed are limited.

Billing program name e.g. B. are in the individual Columns also differ in the number of positions, e.g. B, quantity column 6 digits, price column 4 digits, amount column ten digits. With mechanical reading devices The total number of digits must always be run through, i.e. six digits for four digits Idle.

To avoid these disadvantages, a known output device (German Auslegeschrift 1085 700, in particular Fig. 7) the readout of values, which are displaceably arranged in a contact matrix by the respective layers Actuators are shown. While avoiding roll, rendered cam rollers are operated in a cyclical manner step by step for the individual decades Signal transmitter queried and the circuits of the output switching means assigned to the set values closed one after the other.

Another particularly inexpensive and low-wear design of the signal transmitter to be provided as a relay chain step controller is in one known registration device (German patent 751 8Q9, in particular p. 3, right column, line 113, up to p. 4, left column, line 8) applicable,

The invention is therefore based on the use of the contact matrix readout and on the application trained as a relay chain stepping mechanism. the signal transmitter and the task is the control option for the circuits of the output switching means for the purpose of the digit limiting tone To make the value imprint for office machines selectable.

The solution according to the invention consists in that one of three each controlled via program channels Relay a fixed selectable part of the applied relay chain before the first, Imprint pulse turns on and thereby the imprint of a limited number of printing points take place can.

The advantage of the invention is that the fixed selectable division of the Relay chain. The reading of digit-limited values does not cover the entire step switching time of the complete Relay chain must take to complete and that the location limitation of the print by exchanging the line connections between the three relays and the relay chain can be freely selected at any time.

The invention is illustrated below using an exemplary embodiment described. For a better explanation, before the description of the place-delimited Imprint initially the contact, matrix readout and the application of the relay chain stepping mechanism shown in an office machine.

The toothed racks are connected to toothed wheels. The extinguishing relay 21 switches the contacts 21a and dung, the respective toothed wheel position being a 216, so that the circuit for the relay 22 corresponds to a numerical value. leather sensing contact 23 is contact 21 b is closed.

The first pulse contact 26 opens, and the relay combination including the extinction is in the second pulse contact 27, the second pulse contact is the starting position and is actuated for a new work wheel. The circuit is now ready for the replay. This work cycle begins again with laisll via the contacts 22a and la closed, for example the programmed control of the relay 11 closes the contact lla, its second unit via the preselection contact E.

The remagnet 29 for the pulse device is closed. Iais2 turns on its hold contact 2 g and the relay 28 closes its contacts 28 a and 28 b, contacts 2 a and 2 b. .. 2 / um. Now the contact 28 α interrupts the circuit for the relay 40 and relay 12 controlled by the second pulse contact 27 via the second pulse contact 27, the relay 12 drops out, the contact 28 & opens the circuit for the 5 ° the program channel 33 again Read contacts 12 a and 12 c and closes the contact device and on the other hand the holding circuit 12 b. The first pulse contact 26 now closes the relays 28 and 29. The relay 40, in turn, the circuit for the working magnet switches the contacts 40 a, 40 & and 40 c. Via the 25 via the contacts F, lf, 2f and 3 /, the sensing 55 contact 40a, a circuit for the relay 60 contact 23 and the contact bar 24 is closed. closed, which in turn closes the contacts 60 a, 60 b, the working magnet 25 prints a "1" 60 c and 60 d as the third digit. The contact 60α is parallel, and the first pulse contact 26 interrupts the contact 11a, the contact 60δ parallel to the circuit again, and so on up to the last value point. Contact 12 a, the contact 60 c parallel to the contact

of the pulse contact 26 runs through this up to the contact Tb ... Ij and thus only prints the 7th, 8th, 9th and 10th digits. This reading capacity has therefore been limited to four digits without interrogating the others. If six digits are to be printed, the relay 60 is controlled via the program channel, and the relay 80 is controlled up to eight printing positions. The contacts 60 a, 606, 60 c and 6Oi or 80 a and 80 δ are then actuated and thus the corresponding change in capacitance is brought about. After the last digit has been printed, the extinguishing device comes into operation as described above, with the contact 22 & interrupting the circuit for the relay 28 and the clutch magnet 29, among other things. This also opens the contact 286 and the pulse contacts 26 and 27 de-energized, so that the pulse wheels pass through empty to their starting position.
