Circuit arrangement for Tabulatloneeinrichtungen at electrical typing, billing or similar machines

The invention relates to tine S ohaitunga in order for Tabulafcion devices for electrical writing, Invoicing or similar machines to achieve the shortest possible times and the shortest possible journeys for the typewriter in taboos.

Such facilities that require the least amount of time and Ensure the slightest carriage movements when tabulations are made are already known.

With such a facility, which is a little bit '. Guarantee less time spent on tabular statements, the tab keys assigned to the individual columns of a form are used by the operator the requirements of the Poraulareo operated. So that will a signal flow in a circuit arrangement for tabulating generated, which moves the carriage according to the columns assigned to the keys so that the carriage antweder at its position gate of the column to be controlled at immediately is moved to the selected column without the to stop intervening controllable columns rider but in a fine position behind the controlled one

Column only reaches your controlled column when the car had struck on the right and left hand.

In another known 3inriohtung by means of the special paaten associated with the columns magnets eo excited that they via intermediate links on a With a divisible stop, the sohmltwippa act, which brings an aa chiag cheer to the legends of movement, that this is moved when such a rider hits and with the interposition of elnea braking means a len car drive and the self-contained state troops the magnet interrupting Sohalter acts, ao that the carriage takes the shortest route to the required column, i.e. if the carriage is either at the gate of the column to be controlled, the nonaale tab program is processed, or if the carriage is behind the column to be controlled is located, special keys must be resolved that limit the carriage return cause · The rider anchoring arranged on the rider rail on the carriage can be programmed according to the pormulars to be touched through manual teratelles ·

The facility listed first has the disadvantage that the learways of the wagon continue to occur during tabulatory processes and consequently cause even greater losses of time in the wagon movements, which ultimately has a negative impact on the working speed of the machine affects

Components detrimental to the weight ratios and on the working speed of the machine, there It was necessary to attach additional components to the car. Acts on the operator continue to look unfavorable that they pay more attention to the choice of the appropriate for the form to be filled out Key must lay because duroh the keys provided depending on the car position several columns can be controlled. When executing more extensive Working this device also proves to be disadvantageous, since only a small number can be controlled by columns. The expansion of the columns to be controlled is only possible afterwards mechanical components to be attached possible *

The purpose of the invention is to counteract the aforementioned disadvantages in order to increase the operating speed of the To increase writing, contracting or similar masohines

The invention is based on the object of creating such a tabulation device that the duroh the Tabulation to be carried out carriage movements on deia executes the shortest paths, so that time is lost in the movements of the writing carriage do not occur and the an arbitrarily expandable number of controllable by keys Permits gaps and largely dispenses with mechanical components to reduce the weight of the machine and the to reduce moving masses

According to the invention this object is achieved in that ^ in each column to be controlled a © tab key and a 1-2it-Speieher with existing ones at the entrances and exits AND links are assigned, with the inputs

Before carrying out any work on the Masohine, the condition must be that the carriage is on the left edge of the form at the beginning of the first line. When switched on, the 1-Blt memories 1, 1 · and 1 ", designated as bistable multivibrators, are brewed in such a defined position by means of a Löiohsignala 2 applied to the lower inputs (not shown contact base towards 0 YoIt) that the upper output O ( Zero) and at the lower output the signal L aiii 1 igt · As a result, the B input of the bistable flip-flop 1, 1 * and 1 "and nodes 3, 3 'and 3" is also L. Through the Umsohaltkontakt k, the as long as it remains in the upper position until the carriage returns in the direction of the arrow, a signal L is applied to the voltage plate designated as line input 6 and at the same time to the inputs of the AND nodes 7, 7 'and 7 ". All contacts within the circuit arrangement close ©, hold en line inputs have the task of blocking the AND nodes connected to their outputs when the contacts are open.

Is now in the first according to the rough example Row the column "500 g" (Pig. 3) has been described, the vagina has to be moved by a tab jump in arrow position 8 and brought into the position, that the number 146 can be entered in the "Number" column · Duroh pressing the self-locking tab "* tβ 9" ('lg · 2) becomes the Keypad 29 "arranged locking tab 30" so far moved so that the locking rail 31 the release The magnet 18 engages behind the locking tab 11 "· Thereby

are pressed simultaneously with the tab key 9 " Contacts 9 "a and 9" b closed. By means of contact 9 "a occurs once a contact closure against -12 volts and on the other hand duroh the contact 9" b a connection of a contact point 10 (Fig. 1) with the nooh opened contact 11 b of the magnet for the carriage forward 11 made. The contact closure of the contact 9 "a against - 12 volts causes that over the line input 12 " at the second inputs of the Ünd node 3 "and 13" Signal L is present. However, since there are only 3 "signals L at the two inputs of the AND node, this permeable and gives the signal L to one of the inputs of the OR node 14 - the signal L that is present appears at the exit of the OR node 14 and is through the amplifier 15 amplified so that the connected Magnet for the carriage forward 11 attracts »The excitation of the magnet 11 causes on the one hand the not shown Triggering the carriage movement in the direction of arrow 8 and, on the other hand, closing the contacts 11a and 11b. This Closing the contacts 11 a and 11 b caused by the ^ Contact 11a has a contact bottom against 0 volts in such a way that this 0 volts at the input of the amplifier 16 and thus counteract the excitation of the magnet for the carriage return 17. At the same time it will be Closing the contact 11 b brings about a connection between the excitation winding of the release magnet 18 and the aforementioned contact point 10.

During the carriage movement in the direction of arrow 8, the slides Rigidly arranged grinders on the car: 19 with his Soleplate contacts 20 on the powered with -12 volts Tension bar 21 and on the same side along the contact parts 10 · Both the tension bar 21 and The contact points 10 are also on a Kontaktβchiiae

attached, which is located on the machine frame, not shown · The number of contact points 10 corresponds to the number of possible car hole centers. The tabulator processes are programmed in such a way that a connection is established between the circuit arrangement and the contact point 10 that corresponds to the column to be controlled via a plug-in board 23 (shown symbolically) removed, which allows the signal L to be present via the line inputs 24, 24 'and 2A "at the inputs of the AND nodes 7 and 25, 7 ¹ and 25 * and 7" and 25 ". The AND nodes 7, 7 * and 7 ^W become permeable one after the other and switch the bistable toggle stages 1, 1 · and 1 "in the order in which they are passed over the contact points 10 so that now at the upper output and thus at the inputs of the AND nodes 13, 13 * and 13" the signal L appears and the lower output is 0 (zero). So that the bistable flip-flops 1, 1 · and 1 ⁿ can switch over with the required slope, sim the AND nodes 7, 25, 7 ^f , 25 *, 7 "and 2 5 * an additional input 26 is assigned, which allows high-frequency pike pulses to be present over the entire operating time of the machine. Since the tab keys 9 and 9 ^{f were} not pressed, the AND nodes 13 and 3 and 13 'and 3 ¹ remain blocked.

Simultaneously with the flow of signals at the contact points 10 through the sliding contacts 20 of the soleplate tapped signal L to switch the bistable Toggle levels 1, 1 * and 1 "there is also a signal flow via the connection contact 9 "b of the tab key 9" and contact 11b of the magnet for the car

flow 11 to excite the release magnet 18 · The contact 18a is closed, whereby the amplifier 16 also receives a contact close to 0 volts. When the release magnet 18 is tightened, the locking bar 31 (Fig. 2) assigned to all tabs 9 (9 * and 9 ") is moved in such a way that the tabs 9" are unlocked. In the guide rail 32, which is fixed to the frame, the tabulator device 9 ^B is lifted back into its starting position by the spring 33 ″. In doing so, their contacts 9 ″ a and 9 ″ b are opened and the downstream AND nodes 3 ″ and 13 ⁿ (FIG. 1) no longer receive a signal L «

Because the lower output of the bistable flip-flop 1 "switches to 0 (zero), this" Auegang ne.ch.ges ehalt et e And node 3 "receives no signal L. The AND node 3" is blocked and it No more signal L arrives at the magnet for the carriage advance 11 via the OR node 14 and via the Veretärkei 15 «. The carriage is stopped in its movement in the direction of arrow 8 via mechanical components (not shown). Due to its inertia, the carriage transfers the activated column The falling of the magnet for the car forecourt 11 has the consequence that the contacts 11a and 11b are opened simultaneously 18a. The carriage is now in the position in which the columns "AnEahl ^w _# " characters and numbers "," Price per unit "and" Goods value "of the first line (FIG. 3) are described by the operator can.

After the amount / on 7 * 00 MDN has been written down in the "Value of goods" column (Pig · 3), the operator presses the tab string 9 and thus controls the "kg" column in the next line (Pig. 3). Low stereo discs of the value 4.00 kg an · Bas Pressing the tab key 9 (Pig · 1) has the Polg »that the contacts 9a and 9b of this key are closed, whereby a signal L via the contact 9a via the line input 12 to the inputs of the Ünd nodes 3 and 13 reached. Whenever the bottom of the contact 9b is closed, a connection is simultaneously established between the programmed contact point 10 and the open contact 11b. Signals L are present at the two inputs of the AND-node and are also permeable, so that a signal L is present at the input of the OR-node 27 for the carriage return 17 is reached «via mechanical components, not shown, the carriage movement is triggered by the magnet for the carriage return 17 in arrow direction 5 and at the same time the Umsohaltlcontakt k automatically held in its lower position et · Dl» Aiiaiöffung dir Wagenbewegoag dvroh the magnet for the carriage return 17 equally hosted the drawing of lots not shown in Ztilenaulialturig.

Grammar contact points 10 In reverse order. The signals picked up at the contact points 10 when the vehicle is driven over are, depending on the sequence of the carriage movement, at the inputs of the Ünd nodes 7 ″ and 25% 7 'and 25 * and 7 and 25 · As already described, the inputs 26 of the and Nodes 7, 25, 7'j 25% 7 "and 25" present the Reehteo pulses of high prequens. Since all inputs «the AND nodes 25" »25 'and according to the carriage movement in the direction of arrow 5 carry a signal L one after the other, this causes at their outputs Gate-handing signal In the sequence in which the programmed contact points 10 were passed on, the bistable toggle stage 1% 1 'and 1 * are switched over by switching the bistable _{toggle stages 1 "9} 1 * and 1, the upper outputs 0 (KuIl) and on The signal L is applied to the lower outputs and to the inputs of the connected AND nodes 3 ″, V and 3. Since the tab keys 9 "and 9 * have not been pressed, the sound at the lower outputs of the bistable multivibrators 1" and 1 * at the inputs of the AND nodes 3 "and 3 * pending signals are ineffective ·

When the bistable multivibrator 1 is switched over, the AND node 13 is blocked. There is no longer any signal flow via the OR node 27 and the amplifier 16 'so that the magnet for the carriage return 17 drops out and the Umaohaltkontakt 4 switches back to the upper position. They do not illustrated mechanical decoupling of the carriage movement in the direction of arrow 5 has a delay in such a way to As a result, the car continues to drive a few further wagon ears beyond the controlled column, with the self-locking tab key 9 remaining locked and thus keeps the contacts 9 a and 9 b closed ·.

At this moment, in which the carriage is stopped in its movement carried out in the direction of arrow 5 after crossing the activated column, the initial state is again present _f which was already described for activating the "Number" column in the first line (Pig * 3). The trolley moves back the traversed trolley steps in the direction of arrow 8 in accordance with the already described column control for the trolley advance, without needing a new activation.The control for this is by switching over the bistable tilting stage 1 when driving over the programmed contact parts 1Ö and by locking the tabulator key 9 guaranteed
