Description

The invention relates to cash registers in which the sales amount deposited by a customer The amount and the amount to be returned to the customer as change can be displayed and printed out.

A cash register is already known in which the seller first calculates the sum of a number of in to calculate the items contained in a multi-item transaction in the header, then the one just calculated Indicate the amount to the customer and finally the amount deposited by the customer in the cash register has to register. During this introduction, the seller uses a hand crank in one direction Adjustment of control devices rotated. Then the sales amount is brought in with the hand crank in the opposite direction is rotated. As a result, the control devices are set in opposite directions, so that the corresponding Pressure and display wheels on the difference resulting from the two insertion processes for the setting reach. However, this known machine does not contain any arrangements for adding a reimbursement or discount amount on the final change displayed, which is part of the Represents change billing process, nor means for displaying and printing the sale separately s sum and a final reduced sum.

The object of the invention is a machine pre .j watch is die'bedienungsmäßig easier automatically the sum of a series of multi-item calculated mitbearbei rebate or refund amounts - .. (tet, who called off a subtotal of the sale amount prior to the introduction - or indicates reimbursement amounts, prints and displays a total of the sales amount reduced by the reimbursement amount, and finally ensures the introduction of the business transactions in a more logical sequence, ie by first introducing the sales amount and then the amount paid in by the customer will.

It is also already known for a machine equipped with an adder-subtracter mechanism Provide sum pull buttons, one of which is used to pull positive sums and the other to pull serving negative sums. In this known machine intermediate locking devices are also provided, which can be controlled by the adding-subtracting mechanism in accordance with its algebraic state and are arranged in such a way that only the sum pull key corresponding to the real sum can be pressed, whereas the other key corresponding to the complementary value cannot be pressed.

General

The machine on which the exemplary embodiment is to be described contains for each type of business transaction one adding unit each and one in the upper one to add the items of each individual business transaction Adding unit series accommodated adder-subtracter unit or item adder unit, which upon completion of each multi-item operation and after each single-item operation is emptied.

The adding units are fed via setting mechanisms, which are set in a known manner according to the value of the pressed amount keys will. The setting mechanisms simultaneously effect the setting of a display unit as well the setting of printing units (not shown, as it is known);

All the action buttons are just like the usual ones Motor button Machine release buttons. In other words, by pressing one of these action buttons a machine gear is triggered without pressing the motor button, provided that a Operator key was pressed before the process key.

A depressed operator key remains depressed until it has been assigned to its key bank Release key or by pressing another operator key is released, so that a machine operator not to press the operator key assigned to him again at the beginning of each operation needs. The machine does, however, contain intermediate locks that require pressing the "change" and the "no change" button if the sum control lever is set to "add" (normal position). The "Transfer Amount" key is also open »Add« set total control lever until after completion of a subtotal work step locked against pressing.

In the exemplary embodiment, the labels on the process buttons are "meat", "fruit", "miscellaneous", Tax, No Change, Amount Tendered, Refund, and Change.

The motor button is used to bring in amounts for colonial goods and is therefore marked with "Colonial goods" labeled.

The machine chosen to describe the invention has a front and a rear Adding spindle equipped. Since these adder spindles are known and their description too does not contribute to a better understanding of the invention, a more detailed explanation of the same apart. The "no change" - the "amount handed over" - and the "change" key are not assigned to any adders.

In the case of the introduction of the for a sales transaction taking place under the control of the process buttons belonging items, these are added to the adding-subtracting unit. The one from that The amount given to the cashier by the customer is transferred to the Adding-subtracting work introduced subtractively. As a result, the amount that the cashier appears to the customer and who displayed • when drawing a sum from the add-subtract work and is printed as a negative sum. A release of the machine for this sum move takes place either by pressing the »change or the» no change key. The order is such that if the add-subtract work contains a negative sum, only the "change" - Button can be pressed. However, the amount given to the cashier by a customer is already counted exactly, the adding-subtracting work contains a zero as the sum. In this case just is it is possible to press the »small change key.

Sequence of operations

If the machine is used to calculate the amount to be returned to the customer, then does it work as follows:

First, the operator presses the cashier key assigned to him (left bank of keys in FIG. 1), then the corresponding amount keys and finally the process key (e.g. the colonial goods key, if the Customer bought groceries).

After bringing in all the items, the machine operator sets the total control lever to "subtotal" (the first position above "Add"). Then he presses the motor button, which causes the Subtotal printed on both the check and the control strip and in the display unit is shown. The individual items are only printed on the check.

During the sub-total move the total control lever is automatically in his Normal or "add" position returned.

The machine operator then touches the amount keypad enter the amount given by the customer and press the "transferred amount" - Key in the transaction row, which puts this amount on both the check and the control slip and from that previously displayed as a subtotal in the add-subtract plant standing amount is subtracted.

The machine operator now sets the total control lever to "Item total" (first position below the "add" position) and press the "change" button if the one given by the customer Amount exceeds the amount to be paid (namely the subtotal previously displayed). However, if the customer hands over the exact amount, the “no change” button is used instead of the “change” button pressed. When you press the "Change" button, the change amount and the word "change" displayed in the display and on the check and on the control strip printed. Finally the check is ejected, the cash drawer is opened and the add-subtract mechanism emptied.

The machine is equipped with the following intermediate locks:

The "colonial goods" button is on "item total" set total control lever locked against pressing.

The "change" - and the "no change" - Keys are locked against being pressed when the total control lever is set to "Add". Between these two keys, in turn, have their own intermediate lock, so that if they are not locked at all only one of the two buttons can be pressed at a time.

If the item adder contains a plus amount, then each "transferred amount" work step must be entered

ίο Subtotals can be carried out. With others In other words, this adder must contain a plus amount before the "transferred amount" key is pressed can be.

If, after drawing the subtotal, there is still a tax to be calculated for certain items, so the tax amount is keyed in on the keypad and the "tax" key is pressed, whereby the tax amount is added to the total in the item adder. Then takes place for the purpose Display of the amount now to be paid is again a subtotal statement.

Are at this point in time to the customer repayments for bottle deposit, discount or the like perform, the amount to be repaid is keyed in on the keypad and the »repayment« button is pressed and thereby causing a subtraction operation. After this step, if desired, Draw a subtotal again in the manner described.

drive

The machine used to explain the exemplary embodiment can be driven by an electric motor. Since it is of a known type, only part of the motor coupling is then used described and shown.

A spring-loaded disk 57 (FIG. 2) mounted on a bolt 58 carries a stop 59, which in the starting position of the machine in contact with the front end 60 of one on a Pin 62 mounted arm 61 is. The pin 62 is fixed in the machine frame. One with arm 61 rigidly connected arm 63 carries a pin 64, which is normally on the cam-shaped part 65 of a Arm 66 rests. The arm 66 is driven by a printing unit drive shaft mounted in the printing unit frame 67 carried and is connected via a connecting member 68 with an arm 69, which is on a transverse is pinned through the entire machine extending release shaft 70.

If the arm 69, as described later, is pivoted clockwise (FIG. 2) for the purpose of releasing the machine, so the arm 66 and consequently its cam-shaped part 65 is clockwise below the Pin 64 moved away. This enables a hooked between the arm 63 and a pin, not shown Spring 71, the end 60 of the arm 61 out of 'the path of movement of the attached to the disk 57 Stop 59 to pivot.

The clockwise movement of the arm 63 is controlled by a pin 72 fixed in the machine frame limited. As soon as the end 60 of the arm 61 is pivoted out of the path of movement of the stop 59, a spring, not shown, turns the disk 57 clockwise. This will put between the engine and the drive coupling is connected and the machine is driven.

The main drive shaft 50 of the machine is powered by a gear attached to the drive coupling 73 (Fig. 2) driven off, via an on

an intermediate gear 74 mounted on a bolt 75 fastened in the side wall of the machine, which is connected to the gearwheel 73 is in engagement, and a with the intermediate gear 74 rigidly connected gear 76. which with a gear 77 attached to the main drive shaft 50 meshes. With the gear 76 is also a Gear 78 mounted on printing unit drive shaft 67 in mesh. The main drive shaft 50 and the printing unit drive shaft 67 becomes one complete revolution during an addition machine gear granted.

At the end of the machine cycle, the arm 61 is pinned to the printing unit drive shaft 67 Disk 79 brought back into the blocking position, namely one carried by the disk 79 runs Pin 80 on the edge 81 of the arm 63, whereby this and consequently the arm 61 in a counter-clockwise direction is pivoted. The end 60 of the arm 61 thereby returns to the path of movement of the the disk 57 attached stop 59 and stops the machine. At the same time, the release shafts 70 return and consequently the arm 66 back to its original position.

Cashier keys

According to FIG. 1, there are four cashier keys in groups (from left to right) in the keypad of the machine 82 and an enable key 83, five amount key banks 84, an action key bank 85, a total control lever 87 and a motor button 86 housed.

The cashier keys 82 are used in a known manner to release a lock for the release shaft 70 such that it can be driven by pressing one of the process buttons 85 or the motor button 86 is.

Grocery or motor button

The "colonial goods" or motor key 86 is used to enable the machine during addition operations and for the selection of the adder, in which the amounts received for sold colonial goods zn save are. In the case of subtotal train operations, pressing the motor button 86 turns on Machine gear triggered, but not the addition unit for colonial goods selected for addition.

Sum control lever

The total control lever 87 'is guided in a recess 119 and can be moved up and down into various positions indicated in FIG.

It is used in a known manner to adjust the machine for different types of machine gears, e.g. Addition, subtotal pull, and total pull operations.

example

The machine explained in the exemplary embodiment is a so-called charging machine, in at the end of each business transaction, regardless of whether it is a single item or a multiple item transaction is, a sum move must be prepared in that the sum control lever 87 from its addition position (Fig. 1) down into the next position (item total) is moved.

When calculating the bill of exchange to be repaid to the customer, as already mentioned, after registering the various items (e.g. meat, fruit, groceries) of the Sum control lever 87 moved one step up to the "subtotal" position, then the Motor button 86 is pressed and thereby triggered a machine gear in which the customer to. amount to be paid, as will be described later, is displayed in the display unit. Accepted the bill is DM 3.00, and the customer gives the cashier DM 5.00. The cashier gropes in this case DM 5.00 on the amount keypad 84, press the "Amount transferred" key when the totalizer is set and thereby releases a machine gear

ίο from where the amount of DM 5.00 is displayed and is printed. The cashier then adjusts the total control lever 87 to "item total" (first Position below "Add") and press the "Change" key (because of the negative status in the adder the "no change" key is locked against being pressed). By pressing the "change" key 85 becomes the machine for a total move from the item adder Approved. Shortly before the end of this sum-

In addition, the total control lever 87 is automatically in its normal "add" position put back, the cash drawer opened, the check ejected and the display on the dem Customer is set to the bill of exchange amount to be issued DM 5.00 (in the example DM 2.00) that the Machine automatically calculated during this last step.

It should be mentioned at this point that the total control lever 87 shortly before the end of the machine cycle, in which it was moved one step up to the intermediate total position, automatically is returned to its normal or "add" position.

The whole machine is surrounded by a housing 114, part of which is shown in FIG.

Machine release device

Certain intermediate locks prevent the »no change« key 85 and the from being pressed “Change key 85 when set to“ Add ” Master Control Lever 87.

If the total control lever 87 is in the "add" position, the "transferred amount" key 85 can only be released after a sub-total push button, ie after ^{1 has moved} the total control lever 87 to the sub-total position and a sub-total is in the add -Subtracting work amount has been drawn (the intermediate sum must be positive, ie plus amount). If the adding-subtracting mechanism contains a negative amount when the total control lever 87 is adjusted to "subtotal" (e.g. as a result of a repayment exceeding the purchase amount), the machine cannot be opened due to the excessive state of the adding-subtracting mechanism Press the motor button 86, just start by pressing the "change" button. If, on the other hand, the adding / subtracting mechanism contains a plus amount when the totalizing control lever 87 is adjusted to “subtotal”, the machine can be released by pressing the motor button 86. As soon as the total control lever 87 is automatically returned to its normal position ("add") during this machine operation, the "transferred amount" key is unlocked so that the machine operator can set the amount transferred to him by the customer on the amount keypad and press the " Transferred amount "key 85 is able to trigger a machine operation in which the transferred amount is displayed and printed. After this work-

the machine operator adjusts the total control lever in the first position below "add", namely in the "item total" position, whereby ever either the "change" or the "no change" button depending on the amount transferred by the customer is unlocked. If the amount given to the machine operator matches the amount to be paid, the "no change" button is activated 85 unlocked. However, if the amount transferred exceeds the amount to be paid, then a machine operation can only be triggered by pressing the "change" key 85, in which the change amount (this is the amount that is to be returned to the customer) automatically calculated in the machine will. If, on the other hand, the total control lever 87 is set to “item total”, the “no change” button pressed (because both amounts - the transferred and the payable · - match), so the item adder is reset to zero and the sum 0.00 is displayed.

The following is a description of the device via which, when one of the operation keys 85 or the groceries button 86, the machine can be started is:

In order to be able to trigger a machine gear, the release shaft 70 (FIG. 2) must first be released and by means to be described later for the purpose of releasing the arm 61 and the motor coupling in the Rotated clockwise. Then the machine is already driven by the motor described way.

Initially, the device is to be explained with reference to FIGS. 11, 13, 14 and 15, via which when the motor button 86 is pressed, the machine can be started. The unpressed by a spring 133 Motor or "colonial goods" held in position - key 86 is detachably attached to a slide 130, which is attached to two in the right machine side wall 92 by means of two elongated holes 132 Pins 131 leads. The slide 130 is rotatably connected to a pivotable arm 135. A connecting member 136 is articulated to the arm 135, the right end of which (FIG. 11) has an elongated hole 137, into which a pin 138 fastened in an arm 139 (FIGS. 13 and 14) protrudes. The arm 139 is mounted on an axle 140 supported in the machine side walls 92 and 93 (see also FIG. 6) and carries a second pin 141 (Figs. 13, 14, 15).

A pawl 142, which is also mounted on the axle 140, is normally in the held in the position shown in Fig. 15, in which they with their throat-shaped recess in the arm 139 attached pin 141 engages around. In this position, the right end of the pawl 142 lies in the path of movement of a flattened pin 144, which is in a the engine release shaft 70 pinned arm 145 is attached.

When you press the motor or "Koloriialwaren" button 86, the pawl 142 is over the slide 130, the arm 135, the link 136, the arm 139 and the pin 141 are pivoted in the counter-clockwise direction and brought its front end out of the path of travel of the pin 144. The machine release shaft 70 is now free in a known manner for a clockwise rotation to the machine for one operation to release. When the machine is released, the pin 144 moves under the right end of the Pawl 142 so that the spring 133 can return the motor button 86 to its normal position without the pawl 142 is moved.

Turns shortly before the end of the machine gear

the machine release shaft 70 moves in a known manner in the counter-clockwise direction via its starting position out. This pulls the pin 144 away from under the pawl 142.

Each time one of the action keys 85 is pressed, a known one does not pivot The rod shown is a rotatably mounted on the axis 140 ' Arm 127 counterclockwise (Fig. 13). The arm 127 has an elongated hole 128 into which one of the pin 129 carried by the arm 139 protrudes.

When the arm 127 moves in the opposite direction, the arm 139 is pivoted in the same direction via its pin 129. This causes the pin 141 to lift the pawl 142, thereby, as previously described, the Machine release shaft 70 is released.

Sum control lever

In Fig. 12, the sum control lever 87 is shown in its normal or "add" position. In one In the sum control lever 87 provided mold hole 171 leads a roller 172, which is of a 174 mounted lever 173 is carried, the upper arm 175 has a cam surface 176. A Arm 177, likewise rotatably mounted at 174 and lying above lever 173, has a curved surface 178 on. In the position shown in FIG. 12, the cam surfaces 176 and 178 form the parts described a closed, kidney-shaped shaped hole. A spring 179, on the one hand on one in the arm 175 attached pin 180 and. on the other hand is suspended from a pin 171 carried by the arm 177, holds pin 181 in abutment with the upper end of arm 175 and thereby through the cam surfaces 176 and 178 formed hole closed. This resilient arrangement prevents damage of the machine, if when moving the total control lever 87 from the "add" position to a other position any parts are prevented from moving. One on a shaft 186 Attached arm 185 carries a roller 187, which is in the one formed by the cam surfaces 176 and 178 Form hole leads.

When moving the total control lever 87 from the "add" to the "item total" position the lever 173 via the roller 172 sliding in the mold hole 171 in the counter-clockwise direction and the arm 185 as well the shaft 186 is pivoted clockwise via the arms 175 and 177. During the automatic Return movement of the total control lever 87 to its "adding" position after a total move- or subtotal pull operation becomes the engine enable shaft 70 in in the case of the described Machine type brought back to its normal position in a known manner.

Motor key lock

As already described, the motor key 86 is used for the purpose of performing a subtotal move, d. that is, when the sum control lever 87 is brought into the first position above the "add" position is pressed, thereby starting the machine.

However, if the sum control lever 87 is in the first position below the "add" position - namely is set to the "item total" position, the motor key 86 must be locked against being pressed remain as long as the total control lever 87 is in the "item total" position. The motor

909 690/302

button 86 locking device in this case will be described below.

A connecting member 210 (FIG. 12) is articulated on the total control lever 87, the lower end of which is rotatably connected to an arm 211 pinned on a shaft 212 . The shaft 212 is supported in the machine side walls 92 and 93.

An arm 213 (FIG. 11) having a shaped hole 214 is also pinned to the shaft 212. A pin 215, which is carried by a lever 216 mounted on a bolt 217 , is guided in the shaped hole 214. The bolt 217 is fastened in the machine side wall 92.

In Figs. 11 and 12 the parts are in their Normal positions shown (with totalizer lever 87 set to "Add").

If the total control lever 87 is moved downwards into the "item total" position, the connecting member 210 pivots the arm 211, the shaft 212 and consequently the arm 213 in a clockwise direction. During the pivoting movement of the arm 213 , the pin 215 reaches a deep part 218 of the shaped hole 214. As a result, the lever 216 is pivoted clockwise.

The lever 216 is connected via a connecting member 220 to an arm 221 , which in turn is mounted on the lower of the pins 131 carrying the slide 130 .

During the above-mentioned clockwise movement of the lever 216 , the connecting member 220 is raised and thereby the arm 221 is pivoted clockwise and its surface 222 enters the path of movement of a pin 223 which is fastened in the slide 130 carrying the motor button 86 .

Each time the total control lever 87 is moved to the "item total" position, the arm 221 comes under the pin 223 and prevents the slide 130 from moving downwards and consequently the motor button 86 from being pressed.

Automatic reset

of the total tax lever from the "item total" and "subtotal" position to the

"Add" position

After drawing the total of the items brought in during a multi-item transaction plus tax (if any of the items are taxable) the total tax lever is taken from the "Item total" position automatically returned to the "Add" position. The provision of the total tax lever from the »subtotal« - into the »add« position also takes place automatically. This process is known and is therefore not described in detail.

Amount setting 1 work

The amount setting mechanism is known per se. Suffice it to say that, by pressing an amount key 84 (FIG. 4), an amount switching element 282 with three groups of teeth 330 is set according to the amount entered and that a selectable adder can be inserted into teeth 330.

The setting of the amount switching element 282 is transmitted via a connecting element 322 to a toothed segment 323 which is fastened on one of several nested sleeves 324 carried by an axle 325. The axis 325 is supported in the machine side walls 92 and 93. Each of the tooth segments is used to set an associated display element group in such a way that it displays the value of the pressed keys in two directions of view. The display unit is described below. The connecting member 322 is connected at its lower end to an arm, not shown, which is fastened to one of several nested sleeves via which a known printing unit can be adjusted accordingly.

ίο The teeth 330 of the amount switching element 282 are used to drive the item adder consisting of addition wheels 333 (Fig. 19) and subtraction wheels 334 , which is housed on the upper adder spindle, which is supported in the usual, movable frame 335 (Fig. 3).

The adding units can be engaged and disengaged from the amount switching elements 282 (FIG. 4) in a known manner.

Every time one of the wheels 333 or 334 of the adding-subtracting mechanism rotates from the "9" position to the "0" position, a transmission mechanism is switched in a known manner and the value "1" is transferred to the adding mechanism added in the next highest priority. A ten-switch arm 340 assigned to the group of teeth 330 is rotatably attached to the amount switching element 282. Each tens switch arm 340 has two teeth corresponding to the teeth of the group of teeth 330 and is used in a known manner for effecting tens transmissions.

Display work

The display mechanism of the machine described in the embodiment is known and is therefore only briefly explained.

Each amount key bank 84 is assigned two groups of display members 345 (FIG. 4). One group is visible from the front and the other group from the rear of the machine. Another two groups of display members are assigned to the action key bank 85. Although these display elements are not shown in the drawings, they, with the exception of their inscriptions, correspond exactly to the display elements assigned to the amount key banks. The attachment is the same for all display members and therefore only one display member group will be described below. The display members 345 are arranged in groups in a carriage 347 and rest on transverse strips 348 of a running piece 349, which is carried by rollers 350 mounted on bolts 351 . The poles

351 are supported in plates fastened to the machine side walls 92 and 93 by means of screws 353

352 from. The running piece 349 has a toothing 354 which meshes with the toothed segment 323 which is adjustable under the control of the pressed amount key 84 . In this way is that corresponding to the keyed-in amount display members has the display members 345 supporting the carriage 347 so adjustable 345 (one in the front and one in the rear G ^ru PP ^{s) of} a lifting frame 357, the front and rear grippers 358, are raised and brought into view position in inspection openings 355. Before the carriage 347 is moved into a new position, the display members raised into the display position during the previous operation are lowered again into their normal positions by the lifting frames 357. The toothed segments 323 each have a locking toothing 359 , with which in a known manner a

judge 360, which is mounted on a shaft 362 by. Arms 361 is carried, cooperates.

The aligner 360 is pivoted in the counter-clockwise direction before the toothed segment 323 is adjusted (Fig. 4) of the shaft 362 disengaged from the toothing 359 and after renewed adjustment of the tooth segment 323 is re-engaged in the toothing 359 by pivoting the shaft 362 clockwise.

A second alignment device is used for direct alignment of the running pieces 349 of the Carriage 347. An alignment member 363 of this device, consisting of an angle iron, has for each track piece has a guide slot and an alignment tooth 364 that mates with one in the track piece 349 incised toothing 365 cooperates. The alignment member 363 is at both ends attached to the horizontal part of an arm 366 which rests on pins 367 carried by the plates 352 is stored. Connecting links 368 are on the one hand on the arms 366 and on the other hand on not shown Arms, which are attached to the alignment arms 361 moving shaft 362, articulated so that at the same time when the aligner 360 is driven, the aligning members 363 are also used to align the carriage 347 are driven.

Operation buttons and their adjustment mechanism

As already mentioned, the key bank 85 (Fig. 1 and 5) includes the keys "meat", "fruit", Miscellaneous, Tax, No Change, Amount Tendered, Refund, and Change.

A pin 105 (FIG. 5) is fastened in the shaft of each process key 85, and when the key is pressed, the machine release shaft 70 (FIG. 16) is pivoted into the release position in a known manner. The pins 105 also cooperate with a locking slide 108 (FIG. 5) carried by arms 109 and 110 attached to a key frame 104. The locking slide 108 has locking hooks 111 , one of which, when the machine is released in a known manner, moves to the right (FIG. 5) of the locking slide 108 over the pin 105 of the pressed button and holds it in the pressed position, while the rest are below of the pins 105 of the unpressed operation buttons 85, locking hooks 111 prevent these operation buttons from being pressed.

A pin 115 (FIG. 9) is attached to the side of each process key shaft opposite the side shown in FIG. 5. The pins 115 cooperate with tooth-like projections 116 of an intermediate locking slide 117 , which is slidably supported on pins 118 fastened in the key frame 104.

9 shows the intermediate gate valve 117 in its normal position, in which its lugs 116 lie directly below the pins 115 of the “change” and “no change” buttons and their pressing when the sum control lever 87 is set in the “add” position impede. The intermediate gate valve 117 is, as described below, adjustable by the movement of the total control lever 87.

During a machine cycle following the pressing of one of the process keys 85 (FIG. 5), a connecting member 416 is adjusted accordingly in a known manner.

The upper end of the connecting member 416 is hinged to a toothed segment 417 fastened to the inner of the nested sleeves 324 and transmits the setting corresponding to the value of the pressed key to an indicator running piece 419, with the toothing 418 of which the toothed segment 417 is in engagement . The runner 419 is similar to the already described runner 349 of the indicator part assigned to the amount key banks and is therefore not described in more detail.

The display members 345 associated with the process key bank are shown in the manner already described raised into the viewing position and have the same labels as the keys assigned to them on, namely "Meat", "Fruit", "Miscellaneous", "Tax", "No change", "Amount transferred", "Repayment" and "Change".

The lower end of the connecting link 416 is rotatably connected to an arm 420 fastened on a sleeve 421. The sleeve 421 is slipped onto the shaft 212 carrying the type setting members for the amount key banks and is rigidly connected to a toothed segment 423 which is used to set type wheels 633 (FIG. 20). The type wheels 633 in turn serve to print the receipt and control strips with the symbols indicating the keys 85 and 86 that have been pressed. The toothed segment 417 (FIG. 5) can also be aligned by the aligner 360.

By means to be described later, a known adder shifting device can be adjusted via the connecting member 416 and the arm 420 so that an adder (not shown) of the front adder row is selected depending on the operation keys pressed. Each of the process keys 85 labeled “meat”, “fruit”, “miscellaneous”, “tax” and “repayment” can select an adder of the front adder spindle for storing the amounts entered on the amount keypad.

Another adder of the front adder spindle is used to accommodate all by pressing the "colonial goods" or motor key 86 for adding machine gears.

The means by which this adder is selected when the "grocery" or motor button 86 is pressed is described below. Since the machine of the exemplary embodiment does not contain the usual zero-stop mechanism working in conjunction with the process keys 85, the adjustment mechanism associated with the process key bank and shown in FIG. 5 moves all the way up to the "9" position when the motor key 86 is pressed. The link 416 travels a path corresponding to this setting. The zero stop shown in Fig. 5 has a special purpose and will be described later.

FIG. 6 shows part of the device used for moving a front adder frame 339. A toothed segment is located on the sleeve 421, which can be adjusted via the connecting member 416 (FIG. 5) 424 (Fig. 6) attached, which is in engagement with a rack 425 attached to a slide 426. The slide 426 leads on screw bolts 427 (only one is shown in Fig. 6) and has a right angle flange 428. A shaped hole is provided in the flange 428 with a adder displacement rod 429 cooperating with adder frame 339 in a known manner. laterally movable.

The following is a description of the device that makes up the add-subtract frame 335 (FIG. 3).

Hch shifts so that either the addition wheel 333 or the subtraction wheel 334 is selected under the control of the adjustment mechanism associated with the action key bank.

A pin 441 is fastened in the adding / subtracting frame 335 and protrudes through a recess of an adding mechanism displacement arm 442 mounted on a bolt 443 . The bolt 443 is fastened in a holder 444 which is carried by rods 445 which are supported in the machine side walls 92 and 93. The arm 442 can be pivoted about the pin 443 in such a way that, depending on whether the motor key 86 or one of the operation keys 85 has been pressed, it moves the adder frame 335 from the adding to the subtracting position or vice versa.

The arm 442 carries a roller 446 which is guided in a groove 447 cut into a segment 448 (FIGS. 3 and 19). The segment 448 is attached to the sleeve 324 used for setting the business transaction indicator and is adjustable under the control of the process buttons 85 via the connecting member 416 (FIG. 5).

The groove 447 in the segment 448 is. designed so (see Fig. 19) that the subtraction wheels 334 are then in opposition to the groups of teeth 330 when the setting mechanism assigned to the operation keys is stopped in the "0", "1" or "2" division. If the segment 448 is set in the fourth to eighth position under the control of the process buttons 85 or in the ninth position under the control of the motor button 86 , the addition wheels 333 are brought into opposition with the groups of teeth 330 . The “1” position shown in Fig. 19 corresponds to the “change” key 85, the “2” position to the “repayment” key, the “3” position to the “amount transferred” key and the “ 4 "position of the" no change "key 85. If the" repayment "key 85 is pressed, the setting element of the process key bank 85 and consequently segment 448 moves into the" 2 "position, in which the subtraction wheels are located 334 are in comparison with the groups of teeth 330 . This is also the case when the "change" key 85 is pressed.

If the setting member is held in the zero position by a means to be described later when the "transferred amount" key is pressed, segment 448 also remains in the "0" position, in which the subtraction wheels 334 are compared the tooth groups 330 are located.

An alignment segment 449 (FIG. 3), with which the aligner 360 works together, is attached to the segment drum 448. This ensures that segment 448 is always exactly in the set position. The adding mechanism displacement arm 442 is guided for lateral movement at its left end by means of two fingers 450 (only one is shown in FIG. 3) in the recesses provided in a holder 451.

Control of the task key bank
associated setting member by the sum control lever

An adjusting lever 455 mounted on a shaft 393 (FIGS. 5 and 16) has an elongated hole in its left arm into which a pin 456 carried by a member of the adjusting mechanism protrudes. On the upwardly directed, segment-like arm 457 of the adjustment lever 455 , a shoulder 458 is provided with which a finger carried by a lever 460

459 cooperates. A lever stored at 461

460 is normally held in abutment with a pin 462 mounted in the sum control lever 87 by a spring 463 . In the position shown in FIGS. 5 and 16, the sum control lever 87 is in the “add” position, in which the pen 462 contacts the finger 459 . holds in inoperative position.

By adjusting the total control lever 87

ίο in the "item total" position, the pin 462 is moved slightly upwards (FIG. 16), so that the lever 460 is moved counter- clockwise by the spring 463 as a result of its incision 465. In doing so, the finger 459 of the lever 460 moves into the path of the shoulder 468, which is arranged in such a way that the setting lever 455 and thus the setting switch mechanism of the process bench is stopped by the finger 459 in the "4" position. The adjustment of the setting switching element of the process bench in the "4" -Stcllung is transmitted via the link 416 to the segment 448 (Fig. 3), so that the Adclitionsrädcr 333 at a Postensummenzug of FIG. 19 in juxtaposition with the Znhngruppcn 330 IU: - wear adjusters are located.

By moving the total control lever 87 to the "item total" position, the print and The machine's display unit has a symbol set, which indicates the following machine gear as the item total tractor gear indicates.

When the total control lever 87 is moved into the "subtotal" position, the pin 462 is moved slightly downwards, so that the lever 460 is moved in the counterclockwise direction by the spring 463 as a result of its notch 466. In doing so, the finger 459 of the lever 460 also enters the path of the shoulder 458, from which it follows that the setting switch of the process bank and the segment 448 are stopped in the "4" position, as in the case of an item total. By moving the total control lever 87 into the "subtotal" position, a symbol corresponding to the following machine cycle is set in the display and printing unit of the machine. If there is no plus amount in the adding-subtracting mechanism at this point in time (if an amount to be repaid is higher than the amount to be paid for the goods purchased), only the "change" key can be depressed, the "no change" button «Key, as described later, is blocked. As already mentioned, pressing the "change" key selects the minus side of the add-subtract function, since the setting element assigned to the operation key bank is stopped in the "!" Position.

Coating device

An overdraft takes place when the amount to be paid out to the customer (e.g. bottle deposit, discount or the like.) The amount added into the plus side of the adder exceeds, and also if the dem The amount transferred and brought in by the machine operator is greater than the amount to be paid because the Amount in the traction wheels of the adding unit is introduced.

A disk 482 having a nose 483 is attached to the plus addition wheel 333 (FIGS. 18 and 19) of the highest value of the adding-subtracting mechanism.

In the case of subtraction operations, the add-subtract work into the position shown in FIG

shifted, in which the subtraction wheels 334 are engaged in the groups of teeth 330 of the amount adjusting members and rotated clockwise as shown in FIG. This causes the addition wheels to move in the opposite direction 333, beyond the zero position, so that a coating takes place and therefore the addition wheel highest priority is turned from »0« to »9«.

With the counter-pointer rotation of the addition wheel 333 of the highest digit range from "0" to "9", the disk 482 is also rotated counterclockwise, so that its nose 483 comes to an extension 481 of an arm 487 and the arm 487 pivots clockwise.

The arm 487 is rigidly connected to a second arm 485 by means of a hub 486. Both arms 487 and 485 as well as the hub 486 are mounted on a bolt 488 (FIG. 18), which is supported on the one hand by a bracket 284 for the highest priority series and on the other hand by a holder 489 also attached to a bracket 284. The arms 485 and 487 carry a bolt 490 which is encompassed by the throat-shaped end of an arm 491 fastened on a shaft 492. The shaft 492 is mounted in the left machine side wall 93 and in the boom 284 of the highest priority row. Both arms 485 and 487 can therefore be pivoted clockwise as a whole. With a clockwise movement of the arms 485 and 487, the arm 491 cooperating with the bolt 490 and the shaft 492 are also pivoted clockwise (FIG. 18).

A plunger 503 is movably attached in an attachment 504 of the holder 489. His upper, forked one The end is tensioned by a spring 506, which is tensioned between the holder 504 and the fork attachment of the plunger 503 is held in permanent engagement with a pin 505 mounted in the arm 485. In the case of the above Clockwise movement of the arms 485 and 487 becomes the plunger 503 the amount of clockwise movement the arms accordingly far in the counter-clockwise direction beyond the dead center position around his Pivot pivot pivoted into a position in which it holds the two arms in their adjusted position for so long holds until the adder-subtracter is returned to the uncoated state.

During the machine operation in which the change amount is calculated, the subtraction wheels 334 are set to zero so that the addition wheels 333 assume their "9" position. During the first addition operation following a “change” operation, the adding-subtracting mechanism according to FIG. 19 is shifted to the right into the addition position. In this position, the nose 483 of the disk 482 is in the movement path of the extension 484 formed on the arm 485. During this addition operation, the adder wheel 333 of the highest value rotates as a result of the switching of the ten switch mechanism through all the value places , so that the lug 483 starts from "9" to "0" on the extension 484, the arms 485 and 487 counter-clockwise back to the in Fig. 18 position shown pivoted and the arm 491 and the shaft 482 via the pin 490 a movement in the same direction granted.

The well-known "fugitive one" device (pfennig correction) becomes effective as soon as the shaft 492 is pivoted through the disk 482 for the purpose of introducing a one into the lowest value row of the adder, and enables negative balances to be printed. This facility is briefly described below.

On the shaft 492 (Fig. 18) an arm 510 is attached, the throat-shaped end of a one in one Arm 512 (Fig. 17) includes pin 511 attached. The arm 512 also has a throat-shaped recess and is mounted on a bolt 513 supported in the machine side walls.

The throat-shaped end of the arm 512 comprises a pin 514 which is fastened in an arm 515 mounted on the shaft 492. In the arm 515, a second pin 516 is attached, which is in an elongated hole

517 of a link 518 articulated at 519 on an arm 520 protrudes. The arm 520 is on a

t5 short shaft 521 attached. The shaft 492 carries a roller 522, which in a manner to be described below with a surface 523 of the link

518 cooperates.

When the shaft 492 is swiveled clockwise in the case of a coating, as already described the arm 510 the arm 512 in the counter-clockwise direction, this by means of its pin 514 the arm 515 in the Clockwise (Fig. 17) and the arm 515 by means of its pin 516 the link 518 around its

The fulcrum 519 counterclockwise, whereby its surface 523 comes into contact with the roller 522. With continued clockwise movement of the arm 515, the connecting member 518, which is still moved in the counterclockwise direction by the pin 516, is displaced on the pin 516 in such a way that the arm 520 and the shaft 521 according to FIG. 17 are pivoted in the counterclockwise direction. At its other end, the shaft 521 carries an arm 530 which is assigned to the ten-switch devices for the series of units and in which a flattened pin 531 is fastened. The pin 531 is in contact with a shoulder of a switch-off device, not shown, for the ten switch arm 340 (FIG. 4). When the shaft 521 is pivoted in the counter-clockwise direction, the pin 531 moves out of the path of movement of said shoulder, so that the ten switching arm 340 moves against the switching element group of teeth, e.g. B. 331, moves and when the amount switching member 282 is reset to the starting position in a known manner, the one-way transmission is effected.

Blocking of the machine release by covering

Found in the add-subtract facility, whether as a result of the introduction of a to the cashier transferred amount or as a result of the contribution of an amount to be paid out that is higher than the amount in the adder, a coating of the adder-subtracter takes place, so becomes a device effective in such a way that the machine release shaft 70 is only activated via the "change" key is drivable.

This device, which is used to lock the mesh release shaft 70, will now be described with reference to FIG Fig. 16 described.

The locking of the machine release shaft 70 is achieved by the occurrence of a coating in the adder-subtracter only prepared and only through the adjustment of the total control lever 87 either on "Subtotal" or "Item total" effective. The machine is, as I said, then only through that "Change" key, but cannot be started using the other process keys 85.

The arm 515 is provided with a hook 541 which normally lies over a pin 542 fastened in a lever 543. The lever 543 is journalled at 544 and has a finger 545 which is normally

909 690/302

is held in abutment with a pin 546 fixed in the lever 460 by a spring 547.

On the pin 542 a connecting member 550 is articulated, which the lever 543 with a on the Axis 140 mounted arm 551 connects. A bracket 552 connects the arm 551 to an arm 553, the carries a pin 554 protruding into an elongated hole of an arm 555. The arm 555 has a finger 556, which is adjustable in the movement path of an arm 557 fastened on the machine release shaft 70.

When the hook 541 releases the pin 542 during a coating, the lever 543 is released from the spring 547 pivoted counterclockwise, provided that the sum control lever is moved from the addition position and thereby the pin 546 has been moved away from the finger 545 of the lever 543. Through the Counter-pointer movement of the lever 543 is via the connecting member 550 of the arm 551, the bracket 552 and the arm 553 is pivoted in the counterclockwise direction and thereby the finger 556 of the arm 555 into the path of movement of the arm 557 mounted on the machine release shaft 70 is moved. The machine release shaft 70 is therefore blocked when the adder-subtracter is overdrawn and the sum control lever is set to either "Subtotal" or "Item Total".

In Fig. 16 the parts are shown in their normal positions. The arm 553 also carries a pin 560, the is in engagement with the revenge-shaped end of a slide 570. The slide 570 appears in the key frame 104 mounted pins 571 and has one normally below the pin 115 of FIG "Change" button 85 lying approach 572 as well as one under the pin 115 of "No change" - Button 85 movable lug 573 on.

If the arm 553, as described above, in a counter-clockwise direction pivoted, the pin 560 pushes the slide 570 downwards so far that the projection 573 directly below the pin 115 of the "no change" button 85 and a recess 574 in it Slide 570 has entered the path of movement of pin 115 of the »change key.

With this setting of the slide 570, the change key 85 is used to enable the machine pushable. When you press this button, you slide on the sloping edge of the recess 574 Pin 115 up the slide 570 so that arms 553 and 555 pivot clockwise and the finger 556 is out of the path of the attached to the machine release shaft 70 Arm 557 is moved. The machine is therefore with excessive add-subtract and open "Subtotal" or "Item total" set total control lever only by pressing the "Change" button releasable.

However, if no coating has taken place, the approach 572 prevents the "change" from being pressed. Button.

Intermediate lock between the sum control lever

on the one hand and the "change" - as well as de.r

"No change" button on the other hand

The following is a description of the device that causes the movement of the sum control lever 87 either in the "subtotal" - or in the_ "item total" position the "change" - and the »no change key 85 unlocked, all others Process buttons 85 are locked in the non-depressed position.

A plate 575 (FIG. 9) having a shaped hole 576 is attached to the total control lever 87 (FIG. 6). A pin 577 is guided in the shaped hole 576, which is fastened in a lever 578 mounted on a shaft 285. In the left arm of the lever 578 is a second pin 579 is attached that goes into a mold hole

580 of an angle lever mounted on a shaft 582

581 protrudes. A pin 583 carried by the bell crank 581 is held by the hook-shaped extension 584

ίο of the intermediate gate valve 117 gripped

According to FIG. 9, when the total control lever 87 moves up or down, the lever 578 via the pin 577 leading in the shaped hole 576 of the plate 575 in a counter-clockwise direction and thereby the angle lever 581 via the pin 579 leading in its shaped hole 580 likewise as far in the Swiveled counterclockwise that the intermediate slide valve 117 is raised and its lugs 116 below the pins 115 of the "change" and "no change" buttons 85 are moved away and further lugs 116 under the pins 115 of the buttons "Repayment", "Amount transferred", "Tax", "Miscellaneous", "Fruit" and "Meat" are moved, so that pressing these buttons is prevented as long as the sum control lever is outside its addition position.

Exercised by pressing the "Amount tendered" key
S tax effects

When pressing the "Transfer Amount" key 85 if the setting element (Fig. 5) assigned to the operation key bank is stopped in its zero position, and thus, according to FIG. 19, the minus or subtraction side of the add-subtract work is selected.

The pin 115 (Fig. 6) mounted in the shaft of the overgenerating amount button 85 is normally in System with a provided on a slide 591 approach 590. The slide 591 leads on in the Key frame for the lowest order amount keys attached to pins 592. The slider 591 engages with its lower, revenge-shaped end around a lever in a zero stop lever 594 (see also Fig. 5) attached pin 593. The zero stop lever 594 is mounted on the axis 285.

A spring 595 acting on the slide 591 holds it in the position shown in FIG. 6 and thereby the zero stop lever 594 outside the path of movement of the setting lever 455 (Fig. 16), the is connected to a link of the business process switching element.

There now follows a description of the device shown in Figure 6, which involves pressing the "Amount Transmitted" key 85 until after at least one plus item has been added to the item totalizer and until after one or more of these adding operations, the adding-subtracting works in a positive one The operations left in the state prevent the following subtotal operation.

If the "transferred amount" key85 is unlocked and pressed in a manner still to be described, so the pin 115 fixed in its shaft pushes the slide 591 downwards, whereby the zero stop lever 594 is pivoted clockwise into the path of movement of the adjusting lever 455, the adjusting member stopped in the zero position and the minus side of the add-subtract unit is selected. the However, clockwise movement of the zero stop lever 594 is normally provided by a fixed therein Prevents pin 600 (FIG. 6) from cooperating with a surface 601 of a slider 602. The slide

Via 602 is hinged to an angle lever 603 and is guided for upward and downward movement on one Pin 599 fastened in the machine side wall. The angle lever 603 is on one in the machine side wall mounted bolt 604 and is held by a spring 605 in its normal position. A link 606 leading on the main camshaft 50 is articulated to the angle lever 603, the carries a roller 607 which cooperates with a cam 608 mounted on the main camshaft 50.

Since the zero stop lever 594 does not move at this point in time corresponding to FIG. 6 can, the slide 591 through the machined at its end, the pin 593 comprehensive throat Prevented a downward movement so that the "Amount Transferred" key cannot be pressed.

During each machine work cycle, the main drive shaft 50, as already mentioned, becomes a full one Clockwise rotation (according to Fig. 6) granted. This causes the cam 608 to move the handlebar 606 to the right pushes so that the angle lever 603 is pivoted in the counterclockwise direction, the slide 602 is raised and the Surface 601 is moved away from pin 600 of zero stop lever 594. In addition operations, the slide 602 is returned to its normal position by the spring 605. Is on the slide 426 a rod 609 attached, which at the fourth position of the slide 426 corresponding point Tooth-like approach 610 has. In the case of which also takes place during a subtotal work step Counter-pointer movement of the angle lever 603 is a screw pin 611 fastened in it accordingly raised far. The slide 426 remains under the control of the switching element 455 to 458 by the Finger 459 (Figs. 5 and 16) on one. Subtotal operation are in the fourth position, the shoulder 610 is below the screw pin 611 (Figure 6). Therefore the. Spring 605 does not pull back the angle lever 603 and the slide 602, so that the surface 601 continues to be outside the path of movement in the zero stop lever 594 attached pin 600 remains. The spring 605 holds the screw pin 611 in contact with either the Rod 609 or with extension 610.

Since the setting of the slide 426 and the rod 609 in the fourth position via the upon completion of each machine aisle in the last setting position remains connecting link 416 (Fig. 5) occurs, approach 610 also remains in it upon completion of the subtotal pull operation location given by approach 610. As a result, the. Area 601 outside the movement path of the pin 600 fastened in the zero stop lever 594. The. "Amount tendered" button So 85 can be depressed, moving the zero stop lever 594 clockwise and the transaction adjuster at the following machine gear is not held in the zero position.

Another lock prevents the zero impact lever 594 from moving clockwise until after insertion of one or more additive items, the add-subtract works before the subtotal Additive item left in the positive state. This locking device comprises a pawl 612, which is mounted on a shaft 613 supported in the machine side walls 92 and 93. on a known arm 614 is also attached to the shaft 613.

A provided on an arm 617 finger 616 is a torsion spring 618 in contact with a in the pawl 612 fixed pin 615 held. The torsion spring 618 on the one hand engages the pin 615 the pawl 612 and on the other hand to a pin 619 fixed in the arm 617. The arm 617 is on the Shaft 613 supported.

The pawl 612 is held in contact with the pin 456 (see also FIG. 16) by a torsion spring 620, on the one hand on a pin 621 fixed in the arm 617 and on the other hand on a in the shaft 613 attached pin 622 engages. Becomes the pin 456 by the transaction adjuster moved upward, the torsion spring 620 pivots the pawl 612 and arm 614 in a counter-clockwise direction.

Fig. 6 shows the pin 456 in the normal position, in deter the pawl 612 holds in the locking position and thereby prevents movement of the zero stop lever 594. When adding an item to the However, as already described, the setting lever 455 (FIG. 16) turns clockwise to add-subtract pivoted and thereby the pin 456 (Fig. 6) moved upwards so that the arm 614 is free and pulled counterclockwise by spring 620. Arm 614 becomes from this position only deferred during a subtotal operation. The pawl 612 is therefore after the completion of a single item entry or after completion the introduction of the last item of several items by sub-totaling the pin 600 of the Zero stop lever 594 free so that the "Transfer Amount" key 85 can be pressed after a subtotal pull operation. In to be described later Thus, the arm 614 is prevented from being removed during the first cycle of a subtotal pull operation under the influence . is reset by springs.

As both the pawl 612 and the surface 601 of the slide 602 now move away from the pin 600 has been, the operator can key in the amount given to him by the customer and the machine start by pressing the "Transfer Amount" key85.

The arm 614 carries at its upper end a roller 623, which is provided in an arm 625, throat-shaped recess 624 slides. The arm 625 hangs on one in the right arm 284 (Fig. 18) attached pin 626. If the arm 614 is in the manner already described by the spring 620 pivoted in the counter-clockwise direction, the roller 623 sliding in the recess 624 pivots the arm 625 clockwise, causing a flattened pin 627 to move in the path of a shoulder 628 of the the sum control lever 87 attached plate 575 arrives.

If the total control lever 87 is now moved upward into its intermediate total position, then it pushes the shoulder 628 of the plate 575 the arm 625 which is guided by means of an elongated hole 629 on the pin 626 upwards, causing a finger 630 to lie behind the roller 623 and a clockwise movement of the arm 614 is prevented when the sum control lever 87 is set to "subtotal".

When the total control lever is reset at the end of the sub-total drawing operation 87 into the normal "addition" position, the arm 625 slides open as a result of its gravity down the pin 626. When the arm 614 is returned to the position shown in FIG. 6, the

flattened pin 627 moved away from shoulder 628 of plate 575. As already mentioned, however, the arm 614 and the pawl 612 remain in their positions assumed after their counter-pointer rotations until after the completion of an item total pulling operation.

The printing unit

Reference is made to FIGS. 7, 8 and 10, which show a check 643 issued by the machine on which a transaction is printed, an offset check 631 of another transaction and part of the control strip 632 printed in the machine.

The check in Fig. 7 shows that the customer has bought meat (Mt) for DM 3, - fruit (Pr) for DM 0.20 and colonial goods (Gr) for DM 0.20 and that the purchase sum DM 3, 40 makes up. The check also shows that the machine operator has drawn and printed a subtotal (DM 3.40) (S ... TL). This subtotal appears not only on the check but also as the last item on the control strip (Fig. 10). DM 0.10 was paid to the customer for a deposit or the like (Rf) and was printed both on the check (Fig. 7) and on the control strip (penultimate item, Fig. 10).

A second subtotal (DM3.30) (S ... TL) was then drawn and printed on the check 634 and on your control strip (Fig. 10, third item from the bottom). The customer gave the machine operator exactly DM 3.30, and this amount was printed with the symbol AT on the check 634 and on the control strip 632 (fourth item from the bottom). Finally, the total control lever 87 was set to "item total", thereby locking the "change" key 85 so that the machine operator could only press the "no change" key 85 and the amount 0.00 (TL) on the check 634 as well as on the control strip 632 (fifth item from the bottom). It should be noted that the items "meat", "fruit" and "colonial goods" were not printed on control strip 632.

Check 631 (Fig. 8) shows that the customer has bought three items of colonial goods (Gr) at DM 0.77, DM 0.60 and DM 1.50 each and that all three items are on check 631, but were not printed on control strip 632. After the entry of the items, a subtotal (DM 2.87) (S ... TL) was drawn and printed on both the check 631 and the control strip 632 (third item from the top). The customer gave the machine operator DM 3.00, and this amount (AT) was also printed on the check 631 and on the control strip (second item from the top). By moving the total control lever 87 to "item total", all keys with the exception of the "change" key were blocked. By pressing the "change" key, the amount of DM 0.13 (Ch) was printed on the check 631st and on the control strip 632.

The usual type wheels 633 belong to the check and control slip printing mechanism (only part of such a wheel is shown in FIG. 20). The print hammer mechanism and the check printing mechanism are known. They are therefore only briefly explained.

However, part of the control strip printing unit and part of the control strip feed device are shown and certain control means for controlling the printing and advancement of the control strip.

Since items such as "meat", "fruit", "miscellaneous", "colonial goods" 5 or "tax" should not appear on the control strip 632, the control strip is fed during the introduction of these individual items by a device and a drive of the print hammer prevented by another device. This device shown in Fig. 20 will now be described.

The control strip 632 is unwound from a supply roll 640 , drawn over guide rollers 641 and rewound onto a take-up roll 642. A ratchet wheel 643, which is driven by a ratchet pawl 644 carried by an arm 645 , is used to drive the take-up roll 642 in the counterclockwise direction. The arm 645 is attached to a lever 646 which carries a pin 648 and which is pulled by a spring 647 acting on it so that its pin 648 remains in contact with an arm 649 which is attached to a shaft 650. An arm 651 is also attached to the shaft 650 via a connecting member

652 with a lever mounted on a bolt 654

653 is connected. The lever 653 carries rollers 655 and 656, which cooperate with cams 657 and 658 mounted on a printing unit drive shaft 659, respectively. The printing unit drive shaft 659 is driven in a clockwise direction from the main drive shaft 50 via gears 662, 661 and 660 during each machine work cycle. The gear 662 is mounted on the main machine drive shaft 50.

During the clockwise rotation of the printing unit drive shaft 659 , the lever 653 is pivoted in the clockwise direction and thereby the link 652 is moved to the left, which results in a counterclockwise pivoting of the arms 651 and 649 . Then, in certain operations to be described below, the pin 648 follows the movement of the arm 649 under the influence of the spring 647 , so that the lever 646 and the arm 645 are pivoted clockwise and the pawl 644 is a short distance further than one tooth pitch of the Switching wheel 643 is moved downwards. As soon as the lever 653 is pivoted back to its original position by the cams 657 and 658 in the counter-clockwise direction, the connecting member 652 pivots the arms 651 and 649 clockwise so that the arm 649 comes up against the pin 648 and the lever 646 and the arm 645 im Swiveled counterclockwise. This has the effect that the pawl 644 rotates the ratchet wheel 643 in the counterclockwise direction by one step and thereby unwinds the control strip 632 from the supply roll 640 and onto the take-up roll 642 corresponding to the extent of a line spacing.

During the introduction of the individual meat, fruit, miscellaneous, tax and grocery items, the movement of the lever 646 under the influence of the spring 647 is prevented by the device to be described below.

The lever 646 has a bend 670 which is held by the spring 647 in contact with a finger 671 of an arm 672 . The arm 672 is mounted on a bolt 673 fastened in the printing unit frame (not shown).

When the business process setting element is set under the control of the “change”, “repayment”, “transferred amount” or “no change” button (corresponding to positions 1, 2, 3 and 4 of the setting mechanism), finger 671 is reached from the trajectory of turn 670,
