Description

Inventors: RL Ditmer, EC Dobberstein and LK Sandor Priority as of November 16, 1956 (USA) The present invention relates to a data recording facility by perforating paper strips with different codes and in particular to a data processing facility capable of recording data taken from a unloading device or from a machine controlled by a keyboard, such as a cash register, a bookkeeping machine or a razor, in a straight line following the strip.

In order to clarify the invention, it is shown in connection with an apparatus used in retail sales for recording data relating to each transaction, such as, for example, data for identifying the seller () or the account or the account with a description of the type of goods and its retail price. The strip, the pH at which this data is recorded, can later be analyzed by means of a razor or by other devices, so that the value of the sales volume, stock holding or other desired data can be obtained. It will be shown to Mart that the described embodiment is only one of Herta's execution forms for different areas.

The recording system Sr described below is intended to be used together with cards or receipts, from which fixed information is read, then Sr said possible. This fixed information is in code form on the cards in the form of a plurality of columns of perforating rows, which are unloaded by the unloading device and recorded on the strip. The use of perforated receipts or cards substantially reduces the number of operations that must be performed by the person who scoops the plant, since the only part required is the insertion of the receipt or card into the unloading device. This simplifies the work and saves considerable time, which largely reduces the error calls when recording a transaction.

Previously, it is possible to use a hook lining system with a sliding card unloading device, a pair of typewriters, which are automatically processed and controlled by the sent cards to draw up invoices or inventory card, a strip punching unit, S0111 is affected by both the hhl cards and the typewriters. saint a programming device, which is controlled by a punched program strip so that the various parts of the system act ph rat "salt. hays at a saclan facility, in contrast to what is the case with a group of cards, which controls a complete transaction. the internship is primarily intended for continuous operation throughout the work period.

According to a different edge system, three slip cards are read for each complete transaction. However, there is an individual scanning mechanism for each card and an individual punching mechanism for each scanning mechanism, the punching mechanism being selectively connected to a control line to punch information from all three cards on a single card and thereby provide a single complete record of the transaction. Since all the cards are used at the same time, it is impossible to determine a certain order for their input.

The present invention differs from prior art devices by its simplicity and the fact that there is only a single scanning means for three input cards and that there are devices for indicating sequence, which allow the punching mechanism to operate only on each of the three cards are inserted into the card unloading device in order.

The recording system described has been extremely flexible and can be easily adapted for the various purposes for which it is intended. The structure is such that it allows programming of a large number of different sequences and operations. In addition, the sequence indicating means, which is built into the card or medium unloading device, can be removed in the form of a closed unit and replaced with another unit, which has other requirements on the order and is thus better suited for other purposes.

The present invention relates to a data processing plant comprising a manually installable calculator for registering a first data class, a medium reading unit for reading a second data class for entering documents from a recording unit, arranged to record both the data classes from the reading unit and the reading unit. different groups of said second data class frail each of a plurality of input documents, which are imported in predetermined sequence, there is arranged a reading control device, which is then controlled by a medium identification device, by means of which the input documents are identified, cooperating with a sequence control device for reading The documents submitted by nal-Janda are prevented from working if a document identified by the medium identification device is not inserted into the unloading unit in the sequence determined by the tracking control device, and it can be characterized mainly by The tracking control device comprises a step switch with successively arranged contact layers, each of which is electrically connected to each of a series of individual contact pairs, of which contact pairs each cooperate with a scanning device, which is arranged to scan identification records in different index layers on the requested documents. that an electrical circuit to a drive motor for the unloading unit is closed only when one of the contact pairs is closed by means of the associated scanning device, which contact pair cooperates with the special contact layer, in which the step switch is instantaneous at a special stage during a data processing operation.

General description.

The illustrated embodiment of the invention includes means for continuously recording on a strip of data obtained from a receipt or card provided with a record and / or from a long-distance controlled data entry machine, such as for example a cash register, a bookkeeping machine or a calculator.

The exemplary embodiment chosen for the purpose of illustrating the invention works with data which are free of retail sale and which can be recorded quickly and accurately on a strip at the same time as the sale takes place. Since data in this way are recorded in the usual sales transaction on a strip at the same time as the transaction is carried out, the values for successive transactions must be recorded in succession on the strip in such a way that the strip can be used immediately to blur a calculator or other data processing devices. whereby inventory control data, sales data, statistical information and other undesirable information can be obtained quickly.

In order to obtain complete information about the sales transaction, which may be required for the production of these various control values and statistical information, it is necessary that a record is made of the sales clerk, customer or account as well as product identification data such as sales price, for each transaction. For custom pre-sold items, the strip will therefore be punched with the clerk's number followed by the customer's or account number in data form and by item identification data, which in turn is followed by data detailing the nature and amount of the sale. The punched segment on the strip, which contains a complete transaction with clerk identification, customer identification, product type data, tax and sum, is called the information block and is distinguished from the underlying information block by >> end of block symbol.

The apparatus includes, as shown in Fig. 1, a recording device 100 which provides a punched strip, a medium discharge device 101 which can control the recording device so that clerk identification data, customer or account identification data and item description data are punched on the strip, and a cash register 102. sales data can be installed to control the recording device so that sales data is stopped. Furthermore, tax, sum and other information can be installed on the cash register Above before registration and registration. The cash register can also check the recording device for punching clerk and customer identification data and product description data when cards, which are intended to be a-vided by the medium unloading device, are not available. The recording device, the medium holding device and the cash register Oro are boarded together by means of cables for cooperating work and, although they are shown in Fig. 1 as separate units, delay the following description will show that the three units form a uniform device, which, if desired, can enclosed in a single housing.

Medium unloading device Or intended to supply the recorder with clerk number identification, customer or account number identification and item description data. This data is read from a receipt or card, which is pre-stamped in accordance with a predetermined code, which represents the information to be read or recorded.

Fig. 2 shows a card 103 for clerk number, on which a clerk identification number is stamped. This card is held by the clerk and inserted into the medium unloading device, as explained below, when the clerk uses the recording device in completing a transaction, in order for a number identifying the clerk to be recorded.

The card shown in Fig. 2 is provided with an identification column and sixteen columns with punched data and, if desired, a longer card with space for additional columns can be used. Usually, however, only seven columns are needed for instantiation of data, as this is sufficient for most purposes. In some cases, it may be inappropriate, as described below, to use lines 2-8 on the cash register keyboard to enter the clerical number in the recording facility, such as when clerical number cards are not used, and the clerical number must be limited to a maximum of seven digits. no two or more operations of the register are performed for this purpose. As an example of data to be punched on the card in Fig. 2, the first column is punched with an identification symbol in the first channel of the first column so that it can be identified as a clerk number card and the following seven columns are punched with a four-digit code, which identifies expedit 0003586. The numbers punched in these columns are also printed on the card for direct control.

In addition to the clerk's identification data, which were stamped and printed on the card, the card may also be provided with printed information about the clerk's name, and, if requested, also information about the department and the store in which the clerk is employed, etc.

In addition to the identification columns and the columns with punched data are the clerk number card, as shown in Fig. 2, provided with two alignment halls 104 and 105, a further hallway 106 and a cut-out part 107. It should be noted that the alignment hall 104 is round, while the alignment hall 105 is rectangular . The medium alignment pins of the medium unloading device have a circular cut-through, but Met 105 is square so that variations in the length of the card, depending on temperature and humidity, can be allowed. The tail 106 cooperates with a store identification pin in the media reader alignment mechanism, which pin is used to check the customer number card, as will be described in the fad.

The cut-out part 107 on the clerk number card coincides with a guard punch on the alignment mechanism of the medium reader, which punch is used in connection with the goods cards, as described below.

Since it is not desired to use the safe distance on the clerk number card, the part of the card that would otherwise be marked is cut away.

Fig. 3 shows a customer number card, on which an identification symbol and a customer or code identification number are stamped. This card is usually held by the customer and handed over to the clerk for entry into the medium unloading device, as will be described below, as the customer makes a purchase, which is not paid for in cash, for a number identification, whereby the customer's number or customer's account number is recorded.

Like the dispatch card 103, the customer number card 108 is provided with sixteen columns, in which data can be punched. Usually, only one identification column and seven data columns are used by these. In the example shown in Fig. 3, the first column is punched with an identification symbol in the second channel of the first column to indicate that it is a customer number card and the following seven columns are punched with a four-digit code, which identifies the customer who has number 1234567. The numbers punched in the various columns are printed on the card to allow direct reading and the customer's name is written there. The card can also be provided with other information, if desired.

The customer number card 108 is provided with alignment halls 109 and 110, a cut-away part 111 and store identification hall 112, corresponding to those pd. the clerk number 103. The cut-off part 111 on the customer number card also has the additional task of cooperating with a raised part on a card holder of the bachelor type so that the card can be releasably retained in the holder. The store identification tail 112 on the customer number card can be placed on any of the layers marked with 113 in Fig. 3. In practice, each of the different layers 113 will be reserved for a separate store in a city or other business area and only a customer number card with the tail 112 in the layer reserved for a particular store can be unloaded by that store's medium unloader, because otherwise, even though a store identification handle 112 is on the card, the control pin will prevent the alignment mechanism of the unloader from completing its movement, so the unloader will not be affected. . The store's clerk number cards and product cards must also be provided with a store identification hall in the steering wheel Page in order for them. should be able to be unloaded by the unloading device, since the alignment mechanism can otherwise not complete - - its movement, whereby the unloading device is not affected.

Fig. 4 shows a three-part product card 116, on which the product corresponding to the product identification data was punched in the store's goods receipt department when the product was received. The card is suitably attached to the product and accompanies it until its sale takes place, at which time it is either unloaded and valued without being removed or even torn off a part of the card and inserted into the unloading device for unloading and recording of associated data.

As shown in Fig. 4, each card portion is provided with twenty-five columns 117 of punched data. The first column on each part is punched with an identification symbol, which has been displayed in channel 4. This symbol identifies the card, such as a goods card and also identifies the type or length of the goods card. As an example of data that can be punched in the remaining columns of the card, the following four columns are punched with a four-digit code 1234, which indicates the manufacturer, the sixth and seventh columns punctuated with numbers 56, which indicate the color of the item, the eighth and ninth columns punched with a code 78 indicating the date of purchase, the tenth, eleventh and twelfth columns punched with 12 1/2, indicating the size of the item, the thirteenth, fourteenth and fifteenth columns punched with 901, indicating the type of the item, the sixteenth and seventeenth columns punched with 23 for indicating the material, the eighteenth and nineteenth carbon hours punched with 45, indicating for which season the product is lit, the twenty-first columns stopped with 45 for indicating in which department the product is said and the twenty-second to twenty-fifth columns with the product price, which has been set at 23.45.

The numbers punched in the different columns are also printed on each of the 116 parts of the card and are distinguished into groups by underlining, so that the different parts of the number can be distinguished by direct unloading. The amount on the card is used only to be able to make a comparison between the original price of the item and the actual sales price, which is indicated by the amount, which is installed on the cash register and forms part of the record of sales data.

In addition to the identification data stamped and printed on the card, the card can also be provided with print indicating other desired data, such as sales tax, which facilitates the clerk's work.

Alignment halls 118 and 119 and a store identification hall 120 are found in each part pd. card 116 and corresponds to the tail of the clerk and customer number cards.

The cash register is arranged to control the recording device so that the data installed on the cash register is stopped. This data may include such information as sales amount, a consecutive reference number, which is different for each of the consecutive transactions and which is intended to be used to identify the transaction, etc.

The recording device 100, which is controlled by the unloading device 101 and the cash register 102, punches a paper strip 124 of the type shown in Fig. 5 on impact. Strip 124 shows the code used to represent data and symbols in the present embodiment. It is obvious that the code shown is only one of many that can be used to represent data.

The control of the recording device by means of the unloading device 101 and the cash register 102 is coordinated by program means, which can be installed so that a number of different punching sequences can be executed, the recording device being controlled by the unloading device and the cash register in cooperation or only by the cash register, according to the necessary values must be recorded on the strip. The unloading device's and cash register's control of the recording device is also coordinated by means of an interchangeable tracking control device, which determines the recording sequence of different data classes, such as clerk number data, customer number data and product data. The sequence control means can be replaced with other similar means for changing the record sequence of different data classes according to Onskan. When the system is to be used, a main power switch 125 (Fig. 1) is closed, which is arranged on the indicator plate of the cash register 102, whereby voltage is supplied to the recording system. This takes place at the beginning of the working day.

Before completing each transaction, the clerk must first press an appropriate key in line 9 on the cash register, which indicates the type of transaction and must then enter a sift clerk number card in the unloading device for unloading and discovery on the strip. When the card is inserted, a unloading operation is started in the unloading device and a record of the unloaded information. The card is seized alive and stored in the unlocking device until all the information on the card has been unloaded, after which it is released. In the following, means will be described which prevent unloading of an incorrect card inserted by mistake or inattention.

After the clerk number card has been unloaded, the assisted customer inserts the customer number card, which he receives from the customer, into the unloading device for unloading and recording, provided that a cash purchase does not apply. In the case of cash purchases, customer number information is not relevant and is therefore excluded. The customer number card is read and the information is recorded in the same way as previously described in connection with the clerk number card.

After the unloading of the customer number card or, in the case of the purchase in cash, the bit number card, a goods card unloading device is introduced for unloading and recording of unloaded data. The product card can be unloaded while it is still on the item or also removed from it, if so. Onskas. The product card is read and the information is recorded in the manner described in connection with the clerk number and customer number cards.

While data is being read and recorded from the goods card, the clerk can influence the cash register keys to set the sales amount and other information, which is entered into the card data, but the cash register is not affected until all data is read from the card in the unloading device and recorded by the cash register. antomatically In-gores and begins to work. During this cash register operation, the values set on the cash register keyboard are transferred to the recording device and punched on the strip immediately after they unload the data values from the unloading device and transfer the data values to the recording device.

In order for the correct operating record to have the cash register, the unloading device and the recording device must be obtained, these are provided with. internal welding devices, which will be described as the various parts of the apparatus are reviewed and the electrical circuits are explained.

Devices are available for entering clerical and customer numbers and product information in the recording facility from the cash register's keyboard, in the event that cards are not used. If the customer or clerk number card is lost or damaged, the clerk reads the vardena frail the damaged card or if the card is missing, from a liggarc or someone else cold, savida he does not have the vardena in memory. For manual entry of product data, the classification lines 7 and 8 are used, as will be described in the 101st. When these different entries have been made, transaction keys in row 1 are used on the cash register's keyboard, to control the machine operation. A "clerk number" key controls the entry of clerk number data, a "customer number" key is used to control the entry of customer number data and a commodity key is used to control the entry of item data. The depression of the steering wheel key during data entry operations affects the electrical circuits so that the cash register can operate without affecting the unloading device.

Internal lasing devices and internal connections Ora when depressing «expeditnum mer» -. or the "customer number" key unloading device idle. These control devices also read the keys in row 1, when a card is inserted into the unloading device. Furthermore, there is a welding device, which makes the unloading device inactive, then. a product description is entered using the cash register's keyboard and vice versa.

The operations of the cash register, the unloading device and the recording device, the programming and the connection of these mechanisms to each other in order to provide a strip with the required information, will become clear from the following, detailed description.

Aledium unloading device.

The medium reading device reads data, cards, receipts or other data-bearing means which are inserted into the device and controls the recording device so that this data is entered on the strip. The unloading device also controls the cash register, so that the operations of these two components are coordinated in the correct manner.

The unloading device in the present embodiment has the capacity to unload an identification column and thirty data columns into a card, receipt or other data-carrying means, each column being perforated in each of the four layers. From the following description it will be apparent that the capacity of the unloading device regarding the number of columns and the number of layers in each column is merely as an example and that the capacity can be varied titanium anticipating the invention.

Card shaft and guide means.

As can be seen from Figures 6, 7A, 7B and 11, the unloading device is provided with a shaft 130 for the cards, receipts or other means provided with records, which are to be unloaded. The shaft is gilded by a front plate 131 and a rear plate 132 which are separated by a spacer plate 133 (Figs. 7A and 11) and extends from a vertical slot in the right side of the machine, as shown in Fig. 7B, to the left of an auxiliary end 287. The extent of the shaft to the right, as shown in Figs. 7A and 7B, allows the vertical slot in the right side of the machine to allow recorded cards or the like of any desired size to be unloaded by the unloading device, as long as the code perforations are placed in a horn. on the card. The front and rear plates, 131 resp. 132, upper edges are cut out at 134 and 135 in, the central part (Fig. 11), so that the cards can be pushed far enough into the shaft to get into the raft position. The upper spirit of the plate 131 is bent outwards, so that a funnel is formed, which facilitates the insertion of the cards into the shaft - - and leads the cards to the steering wheel position in relation to the sensing means.

In the housing of the unloading device there are in cooperation with the card shaft 130 means for controlling the insertion of cards or similar means in the unloading device and for temporarily having such means, after they have been unloaded and ejected from the unloading device.

The unloader is at the top of the front provided with a recess 139 (Figs. 1 and 6) against the card shaft 130. The width of the recess 139 is less than the width of the cards normally unloaded by the unloader, but is wide enough to hold the hand of a person who inserts a card, shall fit in it, which facilitates the placement of the card in the shaft 130. The cut-off portion 134 of the front plate 131 of the saw shaft is formed so as to correspond to the shape of the recess 139.

Two breathing means, 140 and 141 (fig. 1 () eh 6) arc by means of bolts 142 arranged at a gable 143, which forms a part of the upper surface of the unloading device. However, these breathing means extend a transparent guide plate 144, which is provided with semicircular recesses 145 and 146 so that the card can be gripped more easily.

When it is desired to insert a card, receipt or the like in the unloading device for unloading, the card is taken by the clerk and inserted into the card shaft 130. The recess 139 provides space for the hand, like the guide plate 144, which is lined behind, so that the card shaft 130 is accessible.

As soon as a single part of the existing card has been inserted for unloading, as described below, the clerk, or the person shoveling the installation, withdraws the hand, after which the guide plate 144 returns to the layer shown in Fig. 6.

When the card is completely unloaded, therefore, the lamped means push the card upwards when the card shaft 130.

The rear plate 132 of the card shaft is provided with thirty-one columns with hall 170 (Figs. 6 and 11), which columns Arc distributed over the plate immediately below the upper edge of the plate. Each of the said columns contains four hats, which arc are evenly distributed vertically on the plate and which are allowed to allow scanning pins 171 to come into contact with the card, de. this dr in unloading law. The upper part of the plate 132 is also provided with three larger slides 172, through which the alignment pins 173, 174 and 175 (Figs. 7A and 7B) pass, for aligning the card in the steering unloading position. The pins 173, 174 and 175 gh also pass through the alignment hole in the card, to prevent the card from being removed from the unloading layer before the unloading device operating cycle is completed. The upper part of the plate 132 is also provided with a plurality of halves 176 (Fig. 11). A pre-selected hall of these halls passes a store identification pin 177, which checks all customer number cards, as previously mentioned, thereby ensuring that such cards are either issued by or are intended for the store that uses the recording facility. The plate 132 Sr Taurus is provided with a slot 174, through which the stopping surface 179 ph passes a suitable card stopping device.

The front plate 131 has an opening (Fig. 11) through which a staple block 181 (Figs. 6 and 7A) can pass to clamp the card to be unloaded against the rear plate 132, so that the card is retained in the unloading position and prevented & An from slipping during the unloading operation.

Malian the front plate 131 and the rear plate 132 there is a spacer plate 133 (Figs. 7A and 11) for all of the had plates at the desired distance from each other and to allow a card to be placed between the pi: Marna. A spacer coupling mechanism is provided on the spacer plate 133, which is actuated by the card to start the unloading device, when the card is inserted correctly in the shaft. An arm 185 (Figs. 11 and 12) is mounted on the spacer plate 133 by means of a pin 186 and the arm carries at its upper end a drop. with a pin 187 rotatably mounted L-shaped member 188, which is provided with two raised portions 189 and 190. An integral part 191 of the arm 185 is raised high, so that anchoring means are formed for a spring 192, which at its second end is attached to a bent Ora 193 on the L-shaped member 188. The spring struts all the hollow member 188 in the layer shown in Fig. 11. Approximately in the middle of the arm 185, an extension 194 is fixed, which is arranged to cooperate with the actuating means of a snap-current switch. The power switch is equipped with contacts SC23a1 and attached to the rail 202.

DA. a card is neatly inserted into the card shaft 130 and then inserted to the left, the lower part of the card is in contact with the raised surface 190 and the left edge of the card is in contact with the raised surface 189. At the left, counterclockwise, around the pin 186, as shown in Fig. 11. The extension 194 on the arm 185 Or, in such a movement, contact with the actuating means of the contacts SC23a1, whereby these contacts are smoothed. This completes a circuit which starts the unloading device, which will be fully described in the review of the electrical circuits.

Fig. 11 shows that it is necessary for the arm 185 to pivot counterclockwise and thereby actuate the switch so that the contacts SC23a1 are closed, that the Insert card makes contact with both the surface 189 and the surface 190 ph the member 188. If the card only runs completely without the Taurus being moved to the left, as shown in Fig. 11, it will only abut the surface 189 of said member. This results in the member 188 being pivoted clockwise around the pin. 187, without the necessary oscillating movement being supplied to the arm 185 with the demand 194 for the action of the generator. If the card is not moved far enough down for contact with the surface 190 of the member 188, before being brought into contact with the surface 189, the member 188 will only be pivoted counterclockwise around the pin 187, without any rotational motion being applied to the arm 185 and its demand 194 to actuate the switch. . The above switching mechanism therefore ensures that the card to be unloaded is wheel inserted into the shaft of the unloading device before the starting current switch of the unloading device can be affected by the said card.

Conventional means may be provided to limit the insertion of the card into the shaft of the unloading device during unloading.

DO a steering wheel inserted card imparts to the arm 185 (Fig. 11) an oscillating movement counterclockwise, thereby closing the contacts SC2,3a1, a magnet L20 (Fig. 13) will be magnetized and turn the silt armature 212 clockwise, as shown in Fig. 13 and a sea arm 214, which cooperates with an arm 217 and a shaft 215, to which the Oro are attached, will be rotated counterclockwise by means of a pin 211 about the axis of rotation of said shaft.

Counterclockwise movement of the sea arm 214, when the magnet L20 is magnetized, causes an Ora 246 on said sea arm to cooperate with an arm 247 to depress a actuator in a snap current switch, which is mounted in the machine frame and contains contacts L20b1, so that said contacts are opened. The function of the contacts L20b1 will be clarified in connection with the review of the circuits.

Conventional means may be provided for ejecting the card from the unloading device when the unloading operation is completed.

Alignment means for the card and means for identifying the store.

Means are provided for aligning the card and for retaining it in unloading mode in and for unloading in the unloading device. The three alignment pins 173, 174 and 175 (Figs. 7A, 7B, 10 and 14) are arranged slidably in the corresponding hall 172, which pass through a transverse bar 202 and the rear plate 132 in the short shaft 130, said pins engaging in the corresponding hall in the card, which is to be unloaded, to keep said card in the raft unloading mode.

The alignment pins 173, 174 and 175 Oro fixed on. arms 254, 255 and 256, all of which are rotatably mounted on a shaft 215 so as to provide them with the same movement about said shaft and for the alignment pins to be inserted into and out of effective short alignment law.

Engaging and releasing movement is imparted to the alignment pins carrying the alignment pins by means of a yoke 258 (Fig. 14), which is freely mounted on the shaft 215. An arm 259 on said yoke is provided with a pin 260 which cooperates with a flat surface. on the arm 256. A spring 262 resiliently unites the arms 256 and 259 with each other. The second arm 263 of the yoke 258 is provided with a cam slot which receives a roller 265 which is attached to an arm 266 which is freely mounted on a shaft 22,8 and is rotated clockwise about this shaft by a spring which is joined by a joint. arm and with the machine stand. Attached to the arm 266 is a pin 268 which is pressed by a spring (not shown) against a surface of the arm 217 which, as mentioned, is attached to the sea arm 214 so that they perform the same movement.

As already indicated, the magnetization of the magnet L20 (Fig. 13) upon wheel insertion of a card or the like into the unloading device causes the sea arm 214 and associated arm 217 to be moved counterclockwise about the axis 2.15, as shown in Fig. 13. The spring causes the pin 268 and the arm 266, on which it is attached, follows the arm 217, the arm 266 being rotated clockwise about the shaft 228. The interaction between the roller 263 on the arm 266 and the cam slot in the arm 263 on the yoke 258 causes the yoke to rotate about the shaft 215 (Fig. 14). whereby the pin 260 on the yoke arm 259 is brought into engagement with the surface ph of the alignment pin arm 256, so that said arm and the other alignment pin arms 254 and 255, which arms are joined together by the sleeve 257, are pivoted counterclockwise about the shaft 215. The alignment pin arms 256, is thus moved through the Mien 172 and the corresponding hall in the card, which is inserted into the unloading device, to raft align the card for unloading.

It should be noted that in the event that the tail of the card for Wagon reason does not coincide with the arms 254, 255 and 256, the alignment mechanism will not be able to complete its movement until the final stroke and the alignment pins will therefore not damage the card, through. to Ora slippery in it. Part is recalled that motion is imparted to the alignment pin arms by the yoke 258 and that the yoke is in turn adjusted by the arm 266, which arm is pivoted by the spring, as the surface of the arm 217 no longer blocks the pin 268 ph the arm 2.66. The spring has such a force that it can adjust the alignment system affected by the alignment pins, as there is no obstacle in the path of these pins, but not so great that it can push the alignment pins through the card material, as the card openings are not in line with the pins. The pin alignment mechanism will therefore only work - - 9, since a card provided with an alignment hall is steered into the unloading device for unloading.

An extension 270 (Figs. 7A and 10) on the alignment pin arm 254 is configured to cooperate with an actuator on a snap current switch to control the contacts SC20ael and SC2Obel. The switch is attached to a bracket 272, which is attached to the plate 287. Counterclockwise movement of the arm 254 during the magnetization of the electromagnet L20 (Fig. 13) causes the extension 270 on said arm to come into contact with a actuating means for the switch, so that the contacts The SC20ael is closed and the SC2Obel connectors are opened. The functions of these contacts in the operation of the recording system will be explained below in the description of the circuit diagram in Figs. 43A to 43F.

Card holding means.

Means are provided for clamping the card inserted into the medium unloading device in the unloading layer so that the card is retained in the proper unloading layer. A staple block 181 (Fig. 6) is attached to two legs 280, which are wedged on a shaft 281 in the stand of the unloader. The clamp block is provided with grooves, such as at 282 (Figs. 6, 7A and 7B), so that the sensing pins in the sensing mechanism of the unloading device can move freely and be placed so that it can be moved through the cut-away part 180 (Fig. 11) in the front the plate 131 on the card shaft to securely clamp a card or receipt in the steering wheel during the unloading operation.

On a bracket 283, which is fixed to the underside of the clamp block 181, there is a roller 284 fixed, which is arranged to cooperate with a cam disc 285 (Figs. 6 and 21), which is fixed to a shaft 286 in an auxiliary side end 287 (Fig. 7A) in the unloading device and at a bracket 288, which is mounted on a crossbar 289 in the stand of the unloading device. Attached to the shaft 286 is also an arm 290 (Fig. 21) which is joined to a phased shaft 281 freely mounted sea arm 292. A curved surface 293 on the arm 290 is arranged to cooperate with a extension 294 on the sea arm 292, which is provided with a recess at 295 to receive a pin 296, which is attached to the anchor 297 pd. a relay L21 of rotating type, which is arranged in the stand of the unloading device.

A snap current switch with contacts L2lael and L21be1 is attached to the underside of the crossbar 289 by means of a bracket 300. A means on said switch for influencing the contacts is arranged to co-operate with an ear 301 on an arm 302, which is freely mounted on the shaft 281 and attached to the sea arm 292 by means of a sleeve 303, so that the shaft and the sea arm perform the same movement. A surface 304 on said arm normally abuts a pin 305, which is fixed to an arm 306, which is wedged on the shaft 281.

As will be described below, the magnet L21 is magnetized at the time when the alignment pins 173, 174 and 175 move through the corresponding alignment hall in a card or receipt to their work teams. Magnetization of the magnet L21 causes the armature 297 and the pin 296 to rotate clockwise, as shown in Fig. 21. By the pin 296 and the arm 295 cooperating, a co-movement is transmitted to the sea arm 292 and the arm 302, which is attached to the sea arm. The member 301 on the arm 302 is brought into contact with the actuating means of the switch for the action of the contacts L2lacl and L2lbel. Below this, the surface 304 of the arm 302 is turned to the left, as shown in Fig. 21, out of the blocking layer of the pin 305, so that the arm 306, the shaft 281 and the staple block with the legs 280 are allowed to rotate clockwise. The arm 306 and the legs 280 are, as they are called, wedged at the shaft 281.

At the same time, the arm 290 is pressed by the spring 291 to follow the movement of the sea arm 292, whereby the shaft. 286 and the cam disc 285 are rotated clockwise. The cam disc 285 cooperates with the roller 284 to press the clamp block 181 clockwise around the shaft 281 to the effective clamping layer, in which the card to be unloaded is clamped to the rear plate 132 of the card shaft. The center of gravity is above and to the right of the axis of rotation of the shaft 281, as shown in Fig. 6.

When the unloading of the card or receipt is completed, the magnet L21 and the armature 297, the pin 296, the lever arm 292 and the arm 302 are rotated counterclockwise, as shown in Fig. , which in turn is rotatably mounted on the sea arm 292. WHEN the sea arm 292 moves counterclockwise, the demand 294 on said sea arm cooperates with the curved surface 293 on the arm. 290 to twist the said arm,. axeln. 286 and the cam disc 285 counterclockwise, the saw is shown in Fig. 21. The arm 302, which is attached to the sea arm 292, is also rotated counterclockwise, the ear 301 being moved out of contact with the actuator means, so that the contacts L21ac1 Ater are opened and the contacts L2lbc1 Ater are closed. The counterclockwise movement of the arm 302 also causes the surface 304 of the arm 302 to be moved higher in cooperation with the pin 305 of the arm 306 to rotate said arm, the shaft 281 and the clamping block with associated parts counterclockwise to the layer shown in Fig. 6, which card is clamped.

Survey part.

The scanning means are arranged to read the data values from the card or receipt, column by column, during the time the card is fixed in unloading position in the unloading device by means of the previously described clamping and aligning means. The scanning means in the present embodiment can scan up to four different card or receipt types.

As previously stated, there are scanning means for scanning up to thirty-one columns A of the card, of which the first column to be scanned is usually an identification column for identifying the type of card to be read, while the other columns represent the data to be recorded. Each of these columns may contain perforations in each of the four layers.

The sensing means used in unloading the thirty data-representing columns will now be described. These sensing means differ in some cases from the sensing means used in connection with the identification column, which later means are described later. The four scanning pins 171 shown in Fig. 6 for scanning one of the data-representing columns of the card are arranged one above the other and are identical to one another. Each sensing pin 171 is constituted by a Bowden cable, the front end of which lies in the corresponding hall 170 (Figs. 6 and 11) in the rear baffle 132 of the card shaft 130 and the rear end of which is connected to a coarser contact control rod 315, which has a tip 316 of insulating material. This rod 315 is supported and guided longitudinally in a transverse rod 317, which is arranged between a side end 210 to the right (Fig. 7B) and a side end 318 to the left (Fig. 7A).

Each of the sensing pins 171 (Fig. 6) is arranged to be able to move its points in the longitudinal direction Indian through the front support rail 202, which is mounted between the side ends, a guard 319 and a further support rail 320, which is mounted between the side ends. The front end of the cover 319 projects into the support rail 202 and its rear spirit into the support rail 320.

Each sensing pin 171 is pressed to the left (Fig. 6) by associated spring, for example the spring 321, which forms part of the contact means for converting the sensed values into electrical signals, by means of which the recording device is controlled for recording data on the strip.

The contact bodies are common to the scanning taps for all data-representing columns on. the card and most clearly shown in Figs. 6, 7A and 7B. The contact means are arranged between end caps 322 and 323, which are supported in auxiliary side ends 287 and 324 by two. crossbars 325 and 326.

Four input terminals 327, 328, 329, 3, and 331 are provided between the end caps, each corresponding to a possible data-representing perforation in a column and which are electrically connected to each other over a rail 332.

As can be seen from Fig. 0, one of the usual spring 321s is connected to the associated input connection. A spring is attached as usual to a data-representing column on the card belonging to the input connection, which meant that thirty springs were connected to the input connection 327, which springs each press the associated scanning pin . On analogous salt, thirty springs were joined together with each of the other connections to press associated sensing pins to the left.

As shown in Fig. 6, output terminals 337, 338, 339, 340 and 341 are arranged to the left of each quarter row of the data-presenting columns, which output terminals are common to the columns and which correspond to the tail arranged at the top and bottom.

The springs 321 are arranged to contact the associated output terminals and thereby selectively complete circuits from the common input terminals to one of the various output terminals. The springs thus perform two functions, ie. they press the sensing pins on the left and form the contacts in the circuits controlled by the sensing pins.

The four output terminals 337, 338, 339, 340 and 341 are connected to four sockets 1338 in a section 1336 in a numerical panel 1315 (Fig. 43F) with diodes, which panel is arranged in the recording device 100. The sockets 1338 can be connected by means of plug connections, for example the connection 1337, is connected to sockets, such as 1339, in the number panel 1315, which avert contains diodes, for selection of the punches which are to be actuated in accordance with the data. To simplify the diagram, the thirty contacts connecting an input terminal to an output terminal are shown as a single connector, the contacts SC36a1 representing the thirty contacts, sum connecting the terminals 327 and 337, the contacts SC36a2 representing the thirty contacts connecting the terminals 328. 338, contacts SC36a3 represent the thirty contacts connecting terminals 329 and 339, contacts SC36a4 represent the thirty contacts connecting terminals 330 and 340 and contacts SC36a5 represent the thirty contacts connecting terminals 331 and 341. Contacts SC3a SC2a1 , SC36a4 and SC36a5 in Fig. 43F thus represent the different contacts which can be controlled when scanning each data representing column on the card.

In the normally retracted ends of the sensing pins, the front ends of the pins --- -11 will coincide with the rear plate 132 of the short shaft 130, and the tips 316 of the elongated rods 315, which tips are recessed to receive the springs 321, will keep the springs out of contact with the outlet. .

As each column of scanning pins is released to scan the card, the pins which are in the law with slippage will be able to move to the left, so that associated springs come into contact with the output connections and complete circuits from the input connections to the output connections. corresponds to ay is prevented from moving to the left, thereby keeping its associated springs out of contact with the output connections.

The movement of the scanning pins from their retracted layers to the scanning layers is controlled by a series of arms 342 (Figs. 6, 7A, 7B and 15) which are each assigned to one of the thirty data representing columns. The movement of the arms is controlled by a blocking rod 343, which is common to all the arms and by an individual cam disc 344 in a series of cam discs. The arms are rotatably mounted on a transverse bar 345 and are guided laterally by a combination plate 346, which is fixed to two blocks 347 and 348, which are mounted on the side ends 318 and 210. The arms 342 are pressed counterclockwise, as shown in Fig. 6, in individual cases. springs 349, which are joined to the arms 342 and align the rests 350 on the plate 346.

Each arm 342 is provided with a protruding portion 351 which communicates with the cam disc, and with an upwardly directed finger 352 which engages the four sensing pins of the corresponding column rods 315. The finger 352 of the arm 342 extends along one side of the scanning pins of the column. , as shown in Figs. 6, 7A and 7B. Each arm 342 is also provided with a surface 353 for co-operation with the locking rod 343, so that the scanning pins 171 are aligned in their right layers, except then. the card is unloaded.

The blocking rod 313 extends over the row of cam discs and is in its spirit provided with triangular adjusting pieces 354 and 238, which are mounted in extensions 355 and 356 on blocks 347 and 348 (Figs. 6 and 17). An arm 237 (Fig. 13) is attached pd. the adjusting piece 238 at the right end of the rod 343, and this arm is pressed clockwise by a spring 239 and is rotatably mounted ph a lank 236.

As already mentioned, the magnetization of the magnet L20 Yid at the beginning of a holding operation causes the sea arm 214 to be turned counterclockwise, as shown in Fig. 13. This movement is transmitted to the rod 343 by means of the ken 236 and the arm. 237, the rod being rotated counterclockwise towards the spring 239, whereby the arms 342 (Fig. 6) are released and guided by the cam discs 344 in the cam row.

When a unloading operation is completed, the magnet L20 is demagnetized and the blocking rod is pivoted clockwise on the spring 239 (Fig. 13) to the layer shown in the figures, in which the laze chambers are blocked, so that they cannot move to the left. This blocking function is important, since, as will be described later, a recovery of the chamber row takes place after the unloading operation is completed. When the cam row is returned to the starting position, as a preparation for the next unloading operation, some of the arms of their corresponding cam discs would be thawed at the left and an incorrect unloading and recording would take place, unless they pO. na.got sat prevented from performing such a movement. Della is, however, prevented by means of the blocking rod. 343, which kyarhaller the arms 342, said that they can not gO. at vanster, as already described.

The cam row (Figs. 6, 15, 16, 16A and 17) contains thirty-two cam discs, of which thirty cam discs guide the scanning means for the data representing columns and a cam 357 (Fig. 15) controls the scanning means for the radium identification column. PO. In the same axis 359, as the cam discs described above, there are nine rotary switches with corresponding contact arms for further control of the media clock and which switches rotate together with the cam discs. The shaft 359 is mounted in the right side end 210 (Figs. 7B and 15) and in a plate 360 (Figs. 7A and 15) which is removably mounted on the left side end 318. The plate 360 allows the cam row to be removed for inspection and adjustment. .

A motor 333 (Figs. 6, 7A, 7B and 17) operates when the unloading device is ready for operation and drives the chamber row one-thirty-sixth vary clockwise across a shaft 361 (Figs. 6, 7B and 17), a clutch 362 and gears 363, 364 , 365, 366, 367, 368, 369 and 370 each time the clutch 362, which is a single-speed clutch, is converted. It follows that the coupling 362 must be repaired thirty-six times for each complete vary of the unloading device, including a recovery operation. The coupling is housed in a pair of coupling magnets L22A and L22B, which, da. they are magnetized, pulling a blocking member 371 from a tooth 372 pa. coupling, said that the coupling can be rotated a vary. The movement of the blocking means 371 during the magnetization of the magnets L22A and L22B also causes the said blocking means to come into contact with a pin 373, which is attached to a switch arm 374, whereby contacts L22a1 are closed for purposes indicated in connection with the description of the circuits. The circuits for magnetizing the magnets L22A and L22B can also be described in delta context.

Two discs 375 and 376 (Figs. 7B and 17) of laminated pulp attached to the coupling 362 are said to rotate together therewith. Each disc is provided with a strip of conductive material, which moves around a part of the periphery on one side of the disc. Contact arms 377 arranged on the stand of the unloading device cooperate with the conductive disk 375 and form the contacts SC35a1, which are closed between four and one hundred and thirty degrees of the rotational turn of the coupling, and contact arms 378, which are also attached to the frame, cooperate with the conductive disk. 376 and form the contacts SC35b2. The functions of these contacts in the work of the recording system will be explained, as the circuits are described.

The cam discs in the cam row are provided with a recess 379 (Fig. 6), of such a length that it will lie, opposite the projecting part 351 on the arm 342 only in one of the layers of the cam row and have such a slippery surface as the part 351 slides on the periphery of the comb, the arm will be in such a position that the sensing pins are inactive while, on the other hand, when the recess 379 is opposite the part 351, the arm can be rotated counterclockwise and thereby the finger 352 to the left, so that the sensing pins are released for movement to inspect the perforations in the corresponding column and close the required of the contacts SC36a1— SC36a5.

The recesses 379 on the cam discs 344 are helically arranged around the shaft 359 so that a certain arm of the arms 342 releases corresponding corresponding pin pins in a certain position of the core row. In the present embodiment, no unloading of the card takes place, as the coupling 362 is for the first time converted, since this only involved a preparatory operation in the unloading device, which gives the various components of the device time to take up the steering wheel unloading law. Then the clutch. ° If installed a second time, the first column on the left of the card will be scanned. This column is the identification column and the sensing means for this column will be described in the following. When the connection is rearranged for the third time, the second column from the left of the card will be read. This is the first data-representing column and the Ater connection is redesigned, the following data-representing column will be read, and so on.

The unloading device can be controlled to unload all thirty-one columns on the card or other desired number. This control function is performed by "end of card" connectors. In the present embodiment, it has been assumed that there are four different sets of "end of card" contacts, one for each clerk and customer number card and one for each three goods cards of different lengths. »End of card» connectors SC21b1, SC22b1, SC30b1, SC31b1 and SC32b1 are made up of four rotatable switch discs respectively. 384, 385, 386, 387 and 388 (Figs. 15 and 16A), which are attached to the shaft 359 and cooperate with corresponding contact arms 389. Each of the "end of the card" switch cables consists of a disk 390 of artificial mass, in which on both sides is inlaid a strip 391 of conductive material. The strips of conductive material on both sides are joined by a bridge of conductive material, which is inserted into the periphery of the disc. One of the had contact arms 389, which cooperates with each of the discs, forms the input contact while the other forms the output contact. It is clear that as long as the conductive strip of the disc is in contact with the contact arms, current will flow from the input to the output arm. However, when the disc is rotated to a bearing in which the insulating art material abuts one or both of the two contact arms, the electrical connection between them will be broken. A further four rotatable switch discs are attached to the shaft 359 to the left of the cam row (Fig. 15). Doubt of these discs, 392 and 393, cooperate with contact arms 394, whereby contacts SC33a3 and SC33a4 are formed. These contacts were opened in the chamber of the avla.s. the starting device, but closed in all other layers of the chamber. The construction of these "open in the starting layer" contacts is identical to the "end of the card" contacts just described, except that the discs 392 and 393 are arranged to be held in a continuous layer relative to the chamber row in the unloading device, while they The "end of card" connectors are arranged to be installed in different layers around the chamber.

A third disc, 395 (Figs. 15 and 16) is fixedly arranged in relation to the chamber row and is intended to cooperate with two sets of contact arms 396 and 397, so that a set "closed in the output stroke" contacts SC33b1 is formed. This disc is similar to the discs described above, in that it consists of a body of art material, in which metal strips 398 have been inserted on either side. One of the contact arms 396 on one side of the disc acts as an input contact, while the other contact arm on the same side of the disc acts as an output contact. Dell therefore states that the contacts SC33b1 will be closed when both the contact arms 396 and 397 are in contact with the metal strip 398 on the disc 395 during a certain part of the rotation of the disc.

A fourth disc 399 on the left side of the cam row is similar to the disc 395 and is arranged to form special symbol contacts SC34a1 in cooperation with the contact arms 400 and 401. The disc 399 dr, in contrast to the disc 395, which the chamber row, so that its relative installation with respect to the chamber row position can be changed as desired.

All rotatable switch discs and cam cam discs are mounted on the shaft 359 (Figs. 6 and 15) in such a way that they can be easily assembled and installed around the shaft, if desired. Wedged on the shaft 359 Indian each pair of cam discs 344 is an arm 402 (Figs. 6 and 15), which is provided with an opening in each spirit. A core disc 344 abuts against each side of the arm 402 and all the cam discs Aro are identical in shape and have a recess 379 of about thirty-six circumferentially evenly distributed slides. Three-armed springs 403 are arranged on the shaft. 359 at the arms 402 and abut against adjacent cam discs 344 to align them with the arms 402 and thereby properly distribute the cam discs on the shaft 359.

The various rotatable switch disks arranged on the shaft 359 are constructed in a similar manner. However, since the switch disks have electrical contact surfaces along the peripheries, it is necessary to align the arms 404, which are attached to the shaft 359, slightly shorter than the corresponding arms 402 used with the cam disks 344, and to provide a recess 405 in the Supreme Spirit on the arms 404 in stall for an Opp-fling, as in the arms 402.

A rod 409 (Figs. 6, 15, 16 and 16A) cooperates with the tail in the cam discs 344 and the switch discs, with the openings in the arms 402 and with the alignments 405 in the arms 404 so that said means can not be rotated in relation to each other and to the shaft 359. The layer of the rod 409 in relation to the shaft 359 is fixed, while the rod passes through the openings and recesses in the arms 402 and 404, which, as already stated, are wedged at the shaft 359. While it is necessary to hold the switch discs 392, 393 and 394 in a particular law with respect to pa. shaft 359 In order to obtain a home or exit bearing, these discs are provided only with a shaft for the rod 409 and cannot be rotatably mounted in relation to the shaft 359. However, the remaining switch discs and the cam discs of the cam row are provided with thirty-six slits each near the periphery. can thus be installed in a desired position by pulling off the rod 409 and turning the disc or cam disc around the shaft 359 to the desired layer, after which the rod 409 is pushed back in and secures all the cam discs and switch discs against rotation in relation to each other.

The scanning means for reading the identification column, which is normally the first column on the card, are integral on the left side of the scanning part, as shown in Fig. 7A. Each of the vertically arranged pins 171, which form the sensing means for the identification column, are longitudinally displaceably arranged in a housing 319, which extends between the posts 202 and 320 pA of the same salt, as the sensing pins for unloading the data-representing card columns. . The rear second pa. each of the sensing pins 171 is connected to a groyre control rod 411 (Figs. 8, 9 and 19), the tip of which is formed of non-conductive material, the rods 411 being supported and guided in the longitudinal direction in the transverse rail 317. Each pin 171 in the identification clamp is pressed At the left of an individual spring 413 (Fig. 20), which abuts against the tip 412 on the end of the rod 411. The spring. 413, the web forms part of the contact means for converting sensed data into electrical signals for controlling the recording system, in accordance with the type of card inserted in the unloading device.

After the blocking rod 343 (Fig. 6) proceeds to the silt non-blocking layer of the magnet, L20, the sensing pins 171 in the identification part are controlled to move from their retracted layers to their sensing layers by an arm 414 (Figs. 9 and 21), which is identical to the chambers 342 and which is rotatably mounted on the crossbar 345 and is pulled counterclockwise by a spring 415 (Fig. 21) which is connected to said arm and the plate 346. The arm 411 is guided by the magnet L21 over the Ianken 308, which is rotatably mounted on said magnet and ph a sea arm 416, which is rotatably mounted on the frame part 287, the said length being pressed to the left of the spring, 307, as shown in Fig. 21. At the lower end of the sea arm 416 a pin 417 is attached, which cooperates with a surface 418 ph arm 414 and thereby controls the movement of the arm.

When the magnet L21 is demagnetized, as shown in Fig. 21, the lever arm 416 is installed by the latch 308 under the action of the spring 307 so that the pin 417 cooperates with the surface 418 to block the arm 414, which is actuated by the spring. 415. The scanning pins 171 (Fig. 8) in the identification section can therefore not be moved against the identification layers.

The magnetization of the magnet L21 at the beginning of a unloading operation means that the Milken 308 is redirected At higher against the action of the spring 307, whereby the sea arm 416 is rotated clockwise around its storage point and the pin 417 moves out of the blocking layer, i.e. from the surface 418. The arm 414 can thus wide ..p counterclockwise around the strut under the influence of the spring 415 and release the pins fed. removal of the card identification column. At the end of a short unloading operation, the magnet L21 is demagnetized, whereby the string 308 can be repositioned at the left of the spring 307. In this case, the sea arm 416 is turned counterclockwise and brings the pin 417 into abutment against the surface 418 for the Atterfora arm 414 to the 14 a fig. 1103 svs rat 43: tif tel fh at ga sl fj Si tE st 4: ti 11 lagt, varigenom de ay. ' the controlled sensing pins of the arm 414 are moved to the retracted layers.

An additional rod 419 (Figs. 9 and 19) adjacent each of the rods 411, which is provided with a tip 420 of insulating material, is supported and guided in the longitudinal direction by the transverse rail 317. Each of the rods 419 is pressed to the left, said. as shown in Fig. 19, by a spring 421 acting on the tip 41. The spring 421 also forms part of the contact devices, which are used for recording an identification symbol or various other purposes, as will be described in the following.

Each of the rods 419 is guided by the associated rod 411 and by a frame arm 422 (Figs. 9 and 15), which later is identical to the cam arms 342 and cooperates with the cam disc 357 on the camshaft 359 (Fig. 15). A cut-out part 423 (Figs. 8 and 9) is found on each of the rods 411 and this part cooperates with a cut-out 424 on the associated rod 419. The rods 411 and 419 are located in the transverse rail 317 so that the cut-out parts 423 and 424 are joined together by means of a ball 426 in a bore 425, the diameter of the ball being equal to the length of the bore. An extension 127 of the bore 425 facilitates the insertion of the ball 426 into the bore during assembly.

It is clear that if its long rod 411 remains in the retracted layer shown in Fig. 9, its notch 423 will not lie opposite the bore 425, so the ball 426 will project from the bore into the notch 424 on the rod 419 and retain said scanning portion. sit that it can not be moved to the left.

Upon complete movement, the left side of any of the rods 411, the scanning pin 171 of which passes through a perforation in the identification part of the card will, as shown in Fig. 9, the cut-out 423 of the rod 411 lie opposite the bore 125 in the rod 317. The rod 419 will be reposition on the left by means of its spring 421 (Fig. 20), when the arm 422 Hires the left, as shown in Fig. 9, of the associated cam disc 357 ph the camshaft 359. The cut-out 423 lies opposite the bore 425, the ball 426 does not retain the rod 419, will be moved out of its blocking layer by a surface of the cut-out 424 to the space formed by the cut-out 423. The rod 419 can thus be moved to the left, as shown in Fig. 9, under the influence of its spring 413. The arm 422 and the rod 419 is then brought back to the layers shown in Fig. 9 by further rotation of the cam disc 357, which guides the arm 422.

The contact means for the identification part among the scanning means are shown in Figs. 7A, 19 and 20 and are arranged in the same frame part as the contact means for the data representing part, but are electrically isolated therefrom. The parts of the input connections 327-331 and the output connections 337-341 which lie opposite the rods 411 and 419 have a reduced cross-sectional area, as shown in Figs. 19 and 20. On each of these reduced parts of the input connections 337-341 a sleeve is mounted 428 of insulating material with a flange 429 towards the transition between the reduced and coarser part of each input connection. A first common disc 430 there fixed to the sleeves 428 of the inner connections 337, 338 and 339 adjacent the flange and a second common disc 431 being fixed to the had connections of the had connections 340 and 341 sleeves 428 adjacent the flange 429. A spare collar 432 there mounted on water and one of said sleeves 428 adjacent and in electrical contact with the discs 430 and 431. Adjacent the collar 432 are two washers 433 and 434 of insulating material for electrically insulating the collar. 432 from another spare collar 435, which is mounted on each of the sleeves 428. On the opposite side of the collars .435 and electrically connected thereto is another common disc 436, which has the same shape as the disc 430, of the connections 337, 338 and 339 sleeves have another common disc 437, otherwise identical to the disc 431, on the sockets of the connections 340 and 341. Spacers 438 and 439 keep the various elements pit each of the sleeves 428 at a right distance from the side end 322. The common plates 430 and 43.1 are electrically connected to form an input connection to the collars 432 and the common plates 436 and 437 are electrically connected. united to form an input connection to the collars 435.

On each of the reduced part of the connections 327331 there is a sleeve 440 of insulating material. The springs 413 and 421 of each of the four sensing rods 411 and the four cooperating rods 419 are mounted on the sleeve 440 and separated by the insulating washers 441, one of which is arranged on each sleeve between two of the springs 413 and 421 and the others are arranged between the spring 421 and the spring 321 Or the outermost data column.

Each spring 413 and 421 is in one breath provided with a hook for engaging a corresponding slot in the insulated tips 412 and 420 on each of the rods 411 and 419. The middle portions of the springs 413 and 421 are wound around the sleeves 440 and the other spirits of the springs. extend through openings 442 (Figs. 7A and 19) in disks 443 and 444 and arc sit bOjda, that they form sockets 445 for connection to the circuits of the recording device, which will be completely explained in the description of the diagram according to Figs. 43A-43F.

In the normally retracted layer of the scanning pins in the identification part, corresponding rods 411 and 419 will line the springs 413 and 421 out of contact with the collars 435 and 432. When the scanning pins in the identification part are released for scanning the card, the scanning pin located in the same layer will slip in the card to be able to move to the left, as shown in Fig. 9, so that the corresponding spring 413 comes into contact with the collar 435 united to the input connection 436 and completes a circuit to the socket 445 on said spring. The rod 419 cooperating with the selected rod 413 is moved to the left (see Fig. 9) NW at a time determined by the installation of the cam 42 controlling the cam disc, which arm in turn controls the movement of the rod 419. As a result, the corresponding spring 421 (Fig. 20) can make contact with the collar 432 belonging to the input connection 430 and complete a circuit to the socket 445 on the spring 421.

Rods 411 and 419, which are controlled by sensing pins in the law without perforations, are prevented from moving to the left and come to keep the associated springs out of contact with the associated collars.

Manual removal of cards and switching means.

Manually actuable means are provided for depositing a card, receipt or other recording medium, which has been incorrectly inserted in the card shaft to the right of the unloading part (Figs. 7A and 7B). The Dan in inserted medium will slide past the unloading part and the card stop means in the unloading part to a bearing in which it is inaccessible to the operator. The meltanism with which tin will be described is arranged to enable the removal of such a card from the card shaft. In addition, the manually actuable means control certain electrical contacts, which in turn control the card release and return function of the unloading device, as will be described in the following.

A depressible key or push button 490 (Figs. 1 and 18) is slidably mounted on the auxiliary side piece 324 by means of pins 491 and 492, which are attached to said side piece 324 and which cooperate with vertical slots in the stem 499 of the key 490. The key 490 is normally not held. depressed length of a spring 494, which is fitted between the pin 491 and a pin 495, which is attached to an extension 496 of the stem 493. A long pin 497 is attached to the stem 493, which pin can be moved freely in a recess 498 (Fig. 17) in the side piece 324. The pin 07 protrudes through a halter in an arm 499 and a U-shaped member 500, both of which are rotatably mounted on a shaft 501, which is fixed to the right side end 210.

The U-shaped member or hygeln 500 has two. pins 502 (Fig. 18), of which only one is shown, extending into the card shaft 130. A projection plate (kite shown) is freely movable on the pins 502 by means of two halves in this plate and arranged in the card shaft. When the key 490 is depressed, the pin 497 rotates the member 500 counterclockwise, whereby the ejection plate is fed upwards into the card shaft 130. Each card, receipt or other medium soni is inserted into the shaft 130 and which lies on top of the ejection plate will therefore be it can be grabbed and removed from the card shaft.

In order to prevent depression of the key 490 during a unloading operation in the unloading device, there are also means, since in the unloading position by means of the alignment and clamping means the card is short on top of the launch plate, whereby the card or unloading device could be damaged.

A pin 504 is attached to the lever arm 214 (Fig. 13), which pin cooperates with a surface 505 on the arm 499. As already mentioned, the lever arm is moved during the magnetization and demagnetization of the magnet L20. When magnetizing the magnet L20, the pin 504 is installed in the surface 505 of the arm 499 path of movement, so that the arm cannot be moved upwards.

This prevents depression of the key 490, as the pin 497 on the stem 493 is blocked against downward movement (Fig. 18). Demagnetization of the magnet L20 causes the spring 239 to move the sea arm 214 clockwise around the shaft 215, the pin 504 being moved from the surface 505 of the arm 499 so that the key can be depressed.

Attached to the rail 289 is a bracket 506 (Figs. 7B and 18), which carried two snap current switches with the contacts SP24a2 and SP24b1, respectively. The actuating means of these stronistallers are held in the accessory layer by a flat end face 507 on the key stem 493, when the key is not depressed. When the key is pressed, the surface 507 is moved downwards (Fig. 8), whereby the actuating means of the stables can move outwards and open the contacts SP24b1 and close the contacts SP24a2. When the key 490 is released, it is moved upwards to the non-depressed laze by a spring 494, whereby the surface 507 abuts against the actuating means of said switch, so that the contacts SP24b1 are closed and the contacts SP24a2 are opened. The functions initiated by the contacts SP24a2 and SP24b1 are fully described in the review of the diagram according to Figs. 43A-43F. 16— - Selector switch unit.

Means for controlling the operating sequence of the recording device are arranged in a unit in the unloading device, which unit can easily be removed and replaced with another unit for another operating sequence.

A base plate 510 (Figs. 6, 22 and 27) supported the components of the switch unit. In working condition, the bottom plate 510 rests on a reel plate 511 in the unloading device.

Adjustment pins 512 in the base plate 511 cooperate with fingers 513 on the base plate 510, so. that steering wheel assembly is secured and screws 514, passed through a slot 515 in the base plate aro threaded in the base plate 511 to secure the had plates to each other. The wires from the electrical components are connected to the connections in two. multiple contacts 516 on a bracket 517, which is fixed to the base plate. The contacts 516 are arranged to cooperate with complementary contact means 516A, which are fixed to the stand of the unloading device, so that electrical connections are obtained between the components of the switch unit and the rest of the recording device.

One of the components of the switch unit is a selector selector or switch 518 having a plurality of rotation angles and contact levels. This switch is arranged between a flange 519 (Fig. 22) bent up from the bottom plate 510 and a vertical part 520 of a bracket 521, which is attached to the hot plate 510. The switch contains a plurality of contact sets and rotatable contact arm means, which later each cooperate with each contact set. . Each contact set includes a first contact portion 522 (Fig. 25) and a second contact portion 523 (Fig. 26). The first contact part comprises a ring of insulating material, which carried four contact sectors 524, each of which is provided with a connection 525, which extends outside the ring. The ring is provided with two diametrically opposed grooves 526, which are provided with one for a bolt 527, for holding the switch together and for mounting it between the flange 519 and the bracket 521.

Each of the contact members 523 comprises a ring of insulating material, in which are arranged twelve evenly distributed short contact sectors 528 of conductive material. Each sector is provided with a connection 529 extending outside the ring. Two diametrically opposite grooves 530 for the same purpose as the grooves 526 are formed on the ring.

Between the contact parts 522 and 523 are contact arm members. 531 (Figs. 23 and 24). Each contact arm member 531 includes a needle 532 attached to it. and axis 533, sa. that they rotate together. Four sets of contact arms 534 are attached to the hub 532 and spaced apart at right angles. Each set consists of two contact springs, the spirits of which are bent at the opposite hall, so that one spring will cooperate with the leading sectors 524 on one of the contact parts 522, while the other spring 534 cooperates with the led sectors 528 in the contact part 523. The shaft 533, on which all the contact arm members 531 are fixed are mounted in the vertical part 520 of the bracket 521 and in the flange 519. The parts 522 and 523 are arranged in a straight line in relation to each other on the flange 519 and the vertical part 520 of the bracket 521 by means of the bolts 527 saint are separated from Hansen 519 by means of spacer sleeves 535 on bolts 527.

The shaft 533 extends through the vertical portion of the bracket 521 and a gear 536 (Figs. 22 and 27) is attached to its spirit. A latch 537 with a tooth 538 cooperates with the teeth on the gear 536 and advances the gear step by step, whereby the shaft 533 and the contact arm members 531 attached are rotated in relation to the contact members 522 and 523. An electromagnet SS20 is attached to the bracket. 521. The magnet SS20 is provided with a rotary anchor 539, on which a pin 540 is arranged, which cooperates with a slot 541 in the latch 537. The slot 541 there is so long that the pin 540 suffers a certain dead center.

Next to the magnet SS20 are two. snap-on switches with the contacts SS20b14, SS20ac13 and SS20bc13, which switches are mounted on a bracket 562 on the base plate 510. The switches are controlled by an arm 563, which are actuated by the magnet SS20 Over an armature 564, which performs an inbound and outbound movement of magnetization. ay magnet.

On the vertical part 520 of the bracket 521, through an pin 542, an arm 543 is rotatably mounted, which arm carries a roller 544 on its one end, which cooperates with a curved stop surface 545 on the latch 537. The arm 543 can be provided with a limited movement for external installation. the roller 544 with respect to the surface 545 of the latch 537 by installing an eccentric 546, which is arranged on the vertical part 520 of the bracket 521 and which cooperates with a slot 547 in the nal-Janda arm. One spirit on a spring 549 is joined by a pin 550 attached to the eccentric 546 and the other spirit by a pin 551 which extends between two Oron on the latch 537 and presses the surface. 545 pa namnda klinka mot rullen 544. Mellan. the pin 551 and the anchor pin 540 are another spring 552, which presses the anchor pin 540 into abutment against the left edge of the slot 541, as shown in Fig. 27.

A leaf spring 553, which is fixedly attached to a shaft ('554), cooperates with the gear of the gear 536 to prevent the wheel from pivoting back. 521 vertical part.

Upon magnetization of the magnet SS20, the fig. The pin 540 cooperates, after passing through the slot 541, with the right edge of the slot and for the latch 537 to move higher against the action of the spring 549, whereby the tooth 538 of the latch is moved behind one of the gears' ends, the gear being locked against return movement clockwise. of the leaf spring 553. When the magnet SS20 is subsequently demagnetized, the latch 537 is moved back so that the left of the spring 549 and the tooth 538 on said latch cooperate with the gear 536 and advance the wheel one step counterclockwise, as shown in Fig. 27. Similarly, with each magnetization and following de-magnetization of the magnet SS20, the gear 536 is advanced one step in the counterclockwise direction.

Figures 25 and 26 show that each set of contact pads 522 and 523 with associated four-pole contact arm 5:11 form four levels or contact sets in the switch. Each of the four sections in the contact field 522 is common to one of the four levels, each level, depending on the twelve sections 528 in the contact field 523, containing three layers. Each of the contact spring sets 534 on the contact arm therefore conducts current from a common sector in the contact field 522 to one of the sectors in the contact field 523 and when the switch is advanced the springs 534 are framed so that the contact spring abutting a sector 528 in the case 523 -goes to a following sector. As a lion stroke spring set is advanced, it passes through a level and then to the first sector 528 in an adjacent level while a subsequent contact spring set 534 is advanced to the first layer in the level left by the first-mentioned contact spring set. An electrical circuit is therefore closed in each level first in layer 1, then in layer 2, then ldge 3, ldge 1 etc. In the embodiment shown, the switch comprises three contact field sets 522 and 523, each of which contains four levels, whereby a total of twelve levels erhallas. However, it is obvious that a switch of this type may comprise any number of levels or any number of layers in each level, if desired.

On the base plate 510 there is also a real K20 with a plurality of contact groups K2Obd1, K20a2, K2Oad1, K2Obdl, K20ac12, K20bc12 and K2Oadll, which are opened or closed during magnetization or demagnetization of the re-Met.

The purpose of the contacts controlled by the selector switch mechanism will be fully explained in connection with the description of the diagram according to Figs. 43A-43F.

To protect the selector switch unit, there is a cover 557. The cover rests on a fitting 558, which is attached to the base plate 510 and is retained by means of a first bolt 559, which is entered in a stand 560 above the standard stands for the plate plate assembly of eli. iiidj: a Lull 161,:., uen är ingangad i konsolen 517.

Recording device.

The recording device, which is of the bachelor type, is generally shown in Figs. 1 and 28. It is arranged to perforate the strip for recording data under the control of program control means in the recording device, under the control of the unloading device and under the control of the cash register.

The recording device can in turn control the unloading device and the cash register, so that these can perform their control functions at the steering wheel instantly. Control functions are included between the recording device, the unloading device and the cash register to prevent further data from being sent to the recording device if it has not recorded recently received data.

As can be seen from Fig. 28, the recording device in the punch mechanism 600 includes a motor 601 for driving the punch mechanism, a capacitor 599 connected to the motor, a coupling 602 for connecting the motor to the punch mechanism, a holder 603 which carries the storage strip, a winding coil 604 on which the punched strip is wound, a control fire part 605 with control winds for coordinating the operations of the cash register, the unloading device and the recording device, a coding unit 609 with diodes and program means 606, comprising a step selector and a plug panel for arranging the the punching sequences required for coordination in sequence following the data entry on the strip under the control of the holding device and the cash register.

The recording device is provided with two plug connections 607 and 608 for the plugged cables, which connect the detection device to the cash register and the unloading device.

A push button PB1 on the front of the recorder was used to start the recorder to perforate the strip on the edge of salt with a joint sample.

Punching mechanism.

It is sufficient to state that the punching mechanism in the known recording device comprises nine punches for punching the perforation rows across the strip, one for each of the eight channels on the strip, which channels are used in combination for coding the data values and one for punching the feed hall.

Fig. 5 shows a fragment of the strip, on which an "end of the block" symbol and the numbers »0» to »9» and a hinge sample part are punched. 18 - - The end of the block symbol is used to indicate the end of an information which belongs to a certain sale of an article or articles for the various information binaries on the strip should be distinguishable. The designations above the strip in Fig. 5 correspond to the data stamped on the strip and the numbers indicated on the side of the strip across the channels.

Each punching operation, whether it involves punching data or a hinge pattern on the strip, also involves punching a feed hall in the strip. These feed halls are used to feed the strip through the punching mechanism and through the sensing means which analyze the strip.

Control part.

The control relay part 605 (Fig. 28) consists of a relay rail 723, which carried the control relays K1 and K2, which are shown in the diagram according to Figs. 43A-43F.

The relay K3, which controls the cash register, unloading device and the recording device to prevent the cash register from being affected when the unloading device and the recording device are operating, is fixed on the bottom plate of the recording device next to the capacitor 599.

The control circuits with the lines K1, K2 and K3 receive DC voltage across a rectifier 598, which is attached to a support plate 725 above the motor. 601.

The program means 606 comprise a per se known step selector and a program unit, consisting of a lower program panel 733 and an upper program panel 734 (Figs. 28 and 43E), which are arranged one above the other.

The step selector has eight levels and can take up twenty layers and is provided with a step magnet SS1 and the normal means for driving the contact arms, which drive means are actuated by a magnetic anchor 729 and are in the driven position, as the magnet is magnetized and drive and advance the arms. when the magnet is demagnetized.

For each program, a selector level is required, whereby the level SSI is used for program I, the level SSII for program II, and so on. The contact levels in the step selector are used for the necessary eight program controls, which programs each contain up to eighteen steps in a punching sequence. To avoid unnecessary repetition, only four levels are shown in Fig. 43D.

Nivan's SSI nineteen first contacts were individually connected to the corresponding sockets in the upper program panel 734, so that the circuits to the various sockets are closed in sequence following the selector arm. on the cash register, as described in detail below. Similarly, the contacts of levels SSII, SSIII and SSIV are individually connected to the corresponding sockets in the Upper Program Panel 734. The twentieth contacts of the different levels are connected to a conductor 1348, by means of which a circuit for incrementing the step selector 726 from the output layer is controlled as described in in connection with the review of Fig. 43A43F.

The lower program panel 733 is provided with a section 735, which contains socket groups, which are connected to the contact arms of the switches SR42a1 — SR48a1 (Fig. 43D), which are assigned to rows 2-8 in the cash register. By conveniently connecting the sockets in the upper program panel 734 to sockets in section 735 by means of plug connections, any desired number of cash register switches can be actuated to control the pick-up device in an unwanted sequence, as the step selector is advanced through its various laws, as explained as Figs. 43A-43F are described.

The upper program panel 734 contains a plurality of kits or sections with sockets, each corresponding to a level in the step selector. In each set or section, each socket is connected to one of the first nineteen contacts in each level of the step selector. The upper program panel 734 also includes a plurality of reset sockets 739, each of which is assigned one of the levels of the step selector and which is connected to each other and to a circuit by which the step selection area is returned to the output layer at the end of a program.

The internal connections between the upper and lower program panel as well as their functions in conjunction with the program control will be fully explained, as the diagram is described.

Coding unit.

The diode coding unit 609, which is of the cand type, shown in Figs. 28 and 43F, comprises a symbol coding panel 1311, the numeric coding panel. 1315, an insulating disc 731 between the hot panels and a bracket 732 for releasably attaching the unit to the bottom plate of the recording device.

Cash register.

The cash register, which forms part of the facility, is of the elective type and will therefore only be briefly mentioned in the 151st description part.

The cash register 102 (Fig. 1) is provided with a keyboard 750, for example of the type shown in Fig. 29 and which is provided with a transaction line 1 with eight keys 752, amount lines 2-6, which lines each contain nine keys 752 , department or classification lines 7 and 8, which lines each comprise Mo keys 753 and a transaction line 9 with four keys 754. At line 1 on the keyboard there is a sum lever - - 19 755, which can be installed in seven different layers for the machine to perform different types of operations. Furthermore, there is a lever 756 for starting certain machine operations. Amount-type amount and transaction differential mechanisms control the installation of certain switches in the machine, as will be described in the following.

Natstromstallare and program panel for the cash register.

For supplying voltage to the recording system in its entirety and individually to the unloading device and the recording device, there are manually actuable current generators.

As already mentioned, the main switch 125 (Fig. 1) is located on the indicator plate of the cash register 102 and is closed for connection of voltage to the recording system. This switch can of course be equipped with a key, so that it can only be actuated by a person who has been assigned a key. The generator is normally affected at the beginning of the working day and switched off at the end of it.

Manual pairable switches (not shown) may be provided to supply voltage to the unloading and recording device, respectively, and these switches may be attached to a rear plate 764 of the cash register. The cash register selection panel 748 is also mounted on the rear plate 764 by means of four pins 747 and is used for setting up various recording programs, as will appear in connection with the description of the circuits according to Figs. 43A-43F.

Control keypad 1.

Pressing a key 751 in row 1 causes a set of contacts belonging to that key to be closed.

Each of the keys 751 is provided with a stem 765, which is arranged to slide vertically in the key frame 766 (Figs. 30 and 32) and which is provided with a pin 767, arranged to be displaceable up and down in a slot 768 in a guide member 769, which is attached to the key frame 766. Each key 751 is fed to its depressed layer by a compression spring 770 which extends between the pins 767 and the key frame 766.

A cam surface 771 on the spirit of each pin 767 cooperates with a socket 772 on a contact spring 773. The spring 773 of each key cooperates with a common input contact 774, so that electrical contacts SC52a1 —SC59a1 are formed for the respective keys 2-9 in row 1. A socket 775 is connected to each of the leaf springs 773 for connecting the contacts SC52a1 — SC59a1 to the electrical circuits of the recording device.

An additional set of electrical contacts SC50a1 is closed when the flake of the keys in row 1 is depressed. The impact means of said contacts will now be described. As can be seen from Fig. 30, a locking member 776 is arranged on the key frame 766 for row 1 with two arms 777 and 778, which are rotatably mounted on the frame 766 and at both ends of the locking member 776. Said locking means is caused to be raised (Fig. 30) by a spring 779, which is fixed to the frame 766 and is provided with locking parts 780, which co-operate with the pins 767 on the keys 751. A second locking member 781 is slidably arranged on the locking member 776. hoger of one connected between the ratchet means. spring 782. The spar member 781 is provided with a cam surface 783 which cooperates with the pins 767 in the keys 751 in the first row. stalks.

A surface 784 of the ratchet member 781 cooperates with a pin 785 on an arm 786, which is rotatably mounted on the frame 766 on the same pivot pin as the arm 777 and which is pressed clockwise, as shown in Fig. 30, by a connector connected between the arm 876 and the frame 766 spring 787. A hook 788 on the spirit of the arm 786 normally engages a square pin 789, which is secured to the ratchet member 776 to prevent this ratchet member from being moved to the right of the spring 779.

The arm 778 (Fig. 30) is provided with an extension 790, which is arranged to cooperate with a roller 791 on an angular arm 792, which is freely mounted on a shaft with a row of key locks 793. The angle arm 792 is slotted in its second end for receiving a roller 794 on one of the arms of another angle holder 795, which second angle holder arm is mounted in the machine frame and rotatably connected to a link 796 (Figs. 30 and 31), which is imparted a rearrangement movement by a slot in the link cooperating with a pin 797, which is attached to a bracket 798 mounted on the machine frame. bracket 806. The arm 801 consists of two parts, which can be installed in relation to each other and constitute the actuating means for the contacts SC50a1 mounted on the plate 764.

Depression of any of the keys 751 iiad 1 entails, in addition to closing the associated contact of the contacts SC52a1 — SC59a1, aft .cp5rrnrgapPt 781 on the sparring organ. The arm 786 is adjusted to the left by the surface 784 cooperating with the pin 785, whereby the hook 788 is brought out of engagement with the square pin 789. Thereby the ratchet member 776 is released and can move upwards and to the right under the influence of the spring 779. The ratchet parts 780 ph engagement with the key pins 767, so that the 71 - - key 751 is read in the depressed state and other keys in line 1 cannot be pressed. The upward movement and Niger of the ratchet member 776 also causes the arm 778 to rotate counterclockwise, so that the extension 790 cooperates with the roller 791, whereby the angle holders 792 are rotated clockwise around the laser row 793. This movement causes the contacts SC50a1 to be closed by the angle lever 79 .

At the end of each operating cycle, the welding row 793 is turned counterclockwise on the edge of the salt. An arm 802 is attached to the welding row 793 and rotates together with it and is provided with a surface 803, which cooperates with a pin 804 on the angle lever 792, when the key laser row 793 is rotated counterclockwise. By the surface 803 and the pin 804 cooperating, the angle holder arm will be pulled with and rotated counterclockwise together with the arm 802. This changes the lane 796 to the left, as shown in Figs. 30 and 31, whereby a spring 805 extending between the arm 801 and the said arm carrying the console, the said arm swings clockwise and opens the contacts SC50a1. The counterclockwise movement of the angle heater 792 is further transmitted via the roller 791 and the extension 790 to the ratchet member 776, which is then lowered and left, as shown in Fig. 30, whereby the ratchet hook 780 on said ratchet member is pulled from the pin 767 on the depressed key in row 1. the spring 770 can return the key to the unaffected position and whereby the square pin 789 is moved to a position in which the Aterigen engages the hook 788 on the arm 786. When the depressed key 751 is returned to the unaffected position, the ratchet member 781 is moved to the right, as shown in fig. 30, of its spring 787. In this unaffected position, the hook 788 engages the square pin 789, thereby preventing the ratchet member 776 from moving upward and to the right until another key in row 1 is depressed.

It is clear that the keys in row 1 are arranged so that the affected contact of the contacts SC52a1 — SC59a1 will be closed before the contacts SC50a1 when a key is pressed, and that at the end of an operation cycle the contacts SC50a1 are opened before the affected contact of the contacts SC52a1 - SC59a1, then corresponding key 751 RprfArps to vilnmge. This has been done so that the contacts SC50a1 in the place of the individual contacts SC52a1 — SC59a1 will stop and break the circuits going over these contacts, which is due to design and service points of view.

Control means for rows 7 and 8.

When a key is pressed into one of or had lines 7 and 8, means for controlling a plurality of electrical contacts are actuated.

Each of the cash register rows 7 and 8 is equipped with a control locking means 810 (Figs. 33 and 35), which is arranged in the key frame of the rows 7 and 8 by means of two arms 811 and 812, which are rotatably mounted on the frame and on the locking means. ets 810 oppositions and which is carried up by a feather (not shown). On the ratchet member 810 there are cam surfaces 813, which lie opposite the pin 814 on the rows 7 and 8 stalks of each key 7531.

An extension 815 on the arm 812 carried a pin 816 which cooperates with a finger 817 on a member 818 which is freely mounted on the cash register 819 of the cash register. A second finger 820 on the member 818 cooperates with a pin 821 on an arm 822 which is freely mounted on the key laser shaft 793. As shown in Fig. 35, the rows 7 and 8 are each provided with a member 818 and an arm 822.

Each of the arms 822 is provided with a cutout which receives the yoke 823 on a yoke 824, which there is provided with arms 825 and 826 which are freely mounted on the key laser shaft 793. The yoke 824 is rotated counterclockwise around the key laser shaft 793 by a spring 827. which is connected to said arm and the left side end 828. At the yoke 821 yoke 823 is attached an arm 829 which is rotatably connected to your lane 830 (Figs. 33 and 34), which is slidably arranged in the machine frame and which extends through a opening in the rear plate 764. The second end of the link is provided with an installable pin 831, which cooperates with a contact spring 832 in a set of contacts SC48ac1 — SC48bel on the plate 764.

When a key 753 (Fig. 29) is pressed into one of or both rows 7 and 8 of the keyboard, the corresponding ratchet member 810 is rearranged downwards and left, as shown in Fig. 33. This movement is transmitted through the arm 812, the member 818 and the arm 822. to the yoke 824 and the darpa fastened arm 829, so that the Milken 8, fores at hoger (fig. 33 and 34). The pin 831 on the link 830 cooperates with the contact spring 832, so that the contacts SC48acl are closed and the contacts SC48bel are opened.

At the end of the operation cycle, a standard release mechanism (not shown) releases the key or keys pressed in rows 7 and 8, whereby the ratchet means of these rows can return to normal. In this case, the pin 816 is moved out of the blocking layer with the finger 817 on the member 818 and the spring 827 is allowed to return the members 818, the arms 822, the yoke 824, the arm 829 and the Milken. 830 to the layers shown in Fig. 33, whereby the contacts SC18ae1 are opened and the contacts SC48bc1 are closed.

Control body for row 9.

When a key in row 9 is pressed, means influence electrical contacts for controlling the operations of the recording facility.

Row 9 in the cash register keyboard 750 is provided with two ratchet members 838 and 839 (Figs. 37 and 36, respectively) with cam surfaces 840 and 841, which cooperate with pins 842 on the keys 754 in Row 9 (Fig. 29) stems 843. Ratchet the member 839 (Fig. 36) has only one cam surface 841, which is opposite the pin 842 pa.

The "Debit" key 754, while the sparring means 838 has four cam surfaces 840 opposite the pins 842 on the "Cash", "Debit", Retaining on delivery "and" Save "keys 754. The sparring means 838 and 839 are provided with slots for pins 844, which are mounted on the key frame for row 9 (not shown), so that said ratchet means can slide in the frame.

On the ratchet member 838 there is a pin 845 which cooperates with a finger 846 on a length 847 which is slidably arranged in the machine frame and which extends through an opening in the rear plate 764. The second end of the link carried a roller 848 which cooperates with a contact spring 849 for a set contacts SC61a1 on the plate 764.

On the ratchet member 839 there is a pin 850, which projects through one of the slots of the ratchet member 838, and cooperates with a finger 851, which is provided with a recess, on a tongue 852, which is slidably arranged on the same member, as the tongue 847, and which extends through an opening in the rear plate 764 and carries a mile 853 with its second spirit, which roller cooperates with a contact spring 854 for a set of contacts SC47acl and SC47bc1, which are merged with the previously mentioned contacts SC61a1 ph. plates 764.

The hinge lanes 817 and 852 are normally pressed to the right by a spring 855, which is arranged between one of the lugs' bearing pins and a pin 856 on the Milken 847 and extends through a slot in the lane 852.

When the flake of the keys 754 is depressed, with the exception of the "Exclusion" key, the pin 842 on this key interacts with the surface 840, so that the locking member 838 is moved to the left. This movement is transmitted through the pin 845 and the finger 846 to the tongue 847 and its roller 848, thereby closing the contacts SC61a1.

If the "Debit" key 754 is pressed, its pin 842, in addition to leading the ratchet member 838 to the left, will cooperate with the cam surface 841 and thereby guide the ratchet member 839 to the left. This movement is transferred from the pin 850 and the finger 851 to the Milken 852 and its roller 853, whereby the contacts SC47acl are closed and the contacts SC47bel are opened.

At the end of the machine's operating cycle, a conventional release mechanism releases depressed keys. The contacts SC61a1 and SC47ac1 are then opened and the contacts SC47bc1 are closed by means of the link system described above.

Selector switch.

The control, classification and amount differential mechanisms affect known switches, some of which control the selection of punches in the recording device for punching the values set by the keys in accordance with a predetermined code, while other switches select a punching program in accordance with other values. functions during the operations of the recording device. These switches will not be described in detail.

The selector switches denoted by SR41a1, SR41a2 and SR41a3 are installed by means of the keys in row 1 of the keyboard, the switches denoted by SR49a1, SR49a2 and SR49a3 are installed by means of the row 9 keys and the class switches .

The corresponding number contacts in the switches SR42a1 — SR48a1 are each connected to the corresponding conductors 888 (Fig. 43D), which go to sockets, ie. all contacts in the "zero" team are connected to the same socket conductor, all contacts in the "one" team are connected to the same socket conductor, and so on. The withdrawal leaders are connected to withdrawals in section 889. on the cash register's selection panel 748.

Switches SR41a1, SR41a2 and SR49a1 contacts aro Taurus connected to sockets in panel 748. The switch's SR41a1 different contacts are individually connected to sockets in a section 890 (fig. 43D) 891 in the panel 748 and the various contacts of the switch SR49a1 are individually connected to sockets in a section. 892 in panel 748.

The remaining sections of the cash register's program panel will be described in detail in connection with the review of Figs.

Switch belonging to the sum lever.

Switching means are controlled by the sum lever 755 and end in the "add" and "sum items" laws and are opened in all other laws.

A segment 988 (Fig. 38) is attached to a shaft 989, which is guided by the sum lever 7 on the edge sail. A slot 990 in the segment 988 receives a pin 991, which is fixed to it on an arm 992, which is rotatably mounted on a pin 993 mounted in the machine frame, the slot having such a shape with a laterally offset portion. , that when the sum lever 755 is in the "add" or "sum records" layer, the pin 991 will be in the laterally offset portion. A long 994 is rotatably mounted on the free spirit of the arm 992 and projects through an opening in the rear plate 764 saint with its second spirit rotatably connected to an angular heater 995 (Fig. 38), which is rotatably mounted on the outer plate 764. attached bracket 996. An extension 997, which is installably mounted on the sea arm 995, is provided with a roller 998, which cooperates with inboard connected spring contacts 999 and 1000 on a set of contacts SC44b1 and SC44b2 on the rear plate 764.

It is clear that when the sum lever 755 is installed in the "addition" - or "sum" of the poster layer from any of the other layers, the laterally displaced portion of the slot 990 will cause the pin 991 covered therein to be rearranged upwards, the arm 992 being pivoted counterclockwise. This movement is transmitted by means of the Milken 994 to the sea arm 995, so that it is turned counterclockwise, whereby the roller 998 presses against the contact springs 999 and 1000, so that the contacts SC44b1 and SC44b2 are closed. These contacts will remain closed as long as the total lever 755 is in the "add" or "total records" position and is restored to the open position, ie the lever is moved to another position.

Switch means associated with the actuating lever.

For the effect of certain switches in the cash register in connection with the lowering of the "influence" lever 756 also for the restoration of said switches to their normal law, special bodies are provided.

The lever 756 is arranged on a slide 1100. On the Milken 1107 there is a stop plate 1113, the upper edge of which normally engages the lower edge of a semi-cylindrical pin 1114, which is fixed on a rod 1115, which is guided downwards by a spring 1116 and which can be imparted. sliding movement by the interaction between a slot 1117 in its lower spirit and a pin 1110 and by the interaction between a slot in its upper spirit and a pin 1118 on the machine frame. An extension 1119 on the upper end of the rod 1115 is provided with a pin 1120, which slides in a slot 1121 in one arm of an angle holder 1122, which angle holder arm is rotatably mounted on the pin 1118. An actuating member 1123 is rotatably mounted on the second arm of the lever arm 1122 and with a slot 1124 for receiving a pin 1125 in the machine frame, whereby the member can be provided with sliding movement. Arranged on the member 1123 is an extension 1126, the free spirit of which carries a roller 1127, which cooperates with the interconnected contact springs 1128, 1129 and 1130 ph contacts SC45a1 and SC45a2 and SC45a3, respectively, which are mounted on the plate 764.

When the lever 756 is depressed, the stop plate 1113 is passed through the arm 1105 and the link 1107 to bear out of the path of the pin 1114 on the rod 1115, whereby the rod is released and Ewes downwards by the spring 1116. 1127 St right, so that said roller cooperates with the inboard connected contact springs 1128, 1129 and 1130 on the contacts SC45a1, SC45a2 and SC45a3 so that said contacts are closed and retained at the end position until the rod 1115 is returned to its normal position.

The rod 1115 is partially lined with the layer shown in Fig. 40 by means of a return holder arm 1131. An arm 1132 is fixed to the tangent row 803. A pin 1133 ph arm 1132 cooperates with a corresponding recess in the shear arm 1131, which Sven Sr attached the tangent.las line, so that said sea arm performs the same movement as the arm 1132. At the end of each machine operation cycle, the tangent string 793 is rotated on edge salt. In this case, the sea arm 1131 comes into contact with the pin 1134 on the rod 1115, when the rod just before continues downwards and moves the rod uplift to the layer shown in Fig. 40. The spring action of the contact springs 1128, 1129 and 1130 causes them to be returned to the IS genes shown in Fig. 40, i.e. the roller 1127 is moved to the left, whereby the contacts SC45a1, SC45a2 and SC45a3 are opened.

The link 1107, which is held in its impacted layer to the right of the layer shown in Figs. 39 and 40 by co-operation between the pin 1114 and the vertical surface 1135 pa. plate 1113, will then be moved to the left of the layer shown in Figs. 39 and 40, by the action of the spring 1112, so that the horizontal surface of the stop plate 1113 will come. is a sparring relation to the pin 1114, whereby the rod 1115 is held in the layer shown in Fig. 40.

Indicator segment controlled switches.

For the influence of certain switches in the cash register under control of the indicator segment in row 1, there are different bodies.

An indicator installation segment 873 (Fig. 40) for row 1 is controlled by the differential mechanism of this row on the edge and is installed in accordance with the layer of said differential mechanism. A disc 1144 (Figs. 40 and 41), which is fixed to the segment 873, is provided with a slot 1145, in which a pin slides, which pin is supported in one breath on a sea arm 1147, which is rotatably mounted between its points on a console 1148, which is fixed on the machine stand. The slot 1145 is provided with a downwardly offset portion in a layer, which corresponds to the differential mechanism layer 4 (or the customer number) and with an upwardly offset portion in a layer, which corresponds to the differential mechanism layer 9 (or the clerk number). A second pin 1149 is attached to the second end of the sea arm 1147 and engages with a fork-shaped portion on an actuator 1150 which is rotatably mounted on a bracket 1151 on the plate 764.

A roller 1152 (Fig. 41) on an extension 1156, which is installably attached to the second end of the member 1150, is arranged to co-operate with a contact spring common to the contacts SC46ac1 and SC46bc1 and with the contact springs 1154 and 1155 joined together, which form parts of contacts SC43a1 and SC43a2. All contacts SC43a1, SC43a2 and SC46ael saint SC46bc1 are fixed on plate 764.

When the differential mechanism of row 1 is installed in any bearing, with the exception of the bearings of 4 and 9, the pin 1146 will be in the main part of the seat 1145, the lever arm 1147 and the payer means 1150 will be in the layer shown in Fig. 41 and controlled by this mechanism. the contacts are in their normal laws. Contacts SC43a1, SC43a2 and SC46ac1 are thus open, while contacts SC46bc1 are closed.

When the differential mechanism for row 1 is installed in layer 4 (or customer base layer), the disc 1144 is rearranged so that the pin 1146 slides into the lower laterally offset portion of the slot 1145, thereby pivoting the lever 1147 counterclockwise and the actuator 1150 clockwise so that the roller 1152 for the connected the contact springs 1154 and 1155 at the right, closing the contacts SC43a1 and SC43a2. The contacts SC46acl and SC46bc1 are affected jokingly and remain thus the apps respectively closed.

When the differential mechanism for row 1 is installed in layer 9 (or the clerk number layer), the disc 1144 is rearranged so that the pin 1146 slides in the upwardly offset portion of the slot 1145 through the hay arm 1147 is rotated clockwise and the actuator 1150 counterclockwise so that the roller 1152 for leaf spring 1153 whereby the contacts SC46bc1 are opened and the contacts SC46acl are closed. Contacts SC43al. and SC43a2 is not affected and remains salunda in the open layer.

Control means for switches, which initiate recording.

For controlling a set of contacts which initiate a recording operation there are means which are controlled by the cash register.

PS the main camshaft 1036 in the cash register there is a cam disc 1161 (Fig. 42), which cooperates with a roller 1162 on an arm 1163, the shaft is freely mounted on a shaft 1164, which is fixed in the machine frame. By means of a sleeve 1165 for a second arm 1166 attached to the frame 1163, which second arm in its spirit carried a pin 1167. A spring 1168 arranged between the arm 1166 and the frame presses the arms 1163 and 1166 clockwise, so that the roller 1162 abuts against the cam disc 1161

The pin 1167 is arranged to co-operate with the lower end of a rod 1169 to guide the rod upwards, Fig. 42, against the action of a spring 1170 extending between a pin 1171 on the upper end of the rod 1169 and a second pin 1172, which is fixed on an angle lever arm 1173 and which slides in a slot 1174 in the rod 1169. One of the arms of the angle shear arm 1175 is rotatably mounted on the pin 1171 ph rod 1169 Upper Uncle. The angle lever 1175 is rotatably mounted on a plate 764 supported. bracket 1176. The second arm of the angle holder 1175 carried an installable mounted extension 1177, the spirit of which carried a rune 1178, which cooperates with the contact spring 1179 on a set of normally open contacts SC42a1.

The cam disc 1161 Sr is so designed that at a rotation of 175 degrees during a machine operation the arms 1163 and 1166 will be rotated counterclockwise (Fig. 42) towards the surface of the spring 1168, so that the rod 1169 is raised upwards against the action of the spring 1170. This movement is transmitted through the angle lever. 1175, the extension 1177 and the roller 1178 to the contact spring 1179, which is advanced, as shown in Fig. 42, closing the contacts SC42a1. These contacts remain closed until the highest point of the rabbit disc 1161 passes the roller 1162, then the spring 1168 returns the arms 1163 and 1166 to the layers shown in Fig. 42 and the spring 1170 returns the rod 1169, the angle lever 1175 and the extension 1177 to the layers shown in Fig. 42. . The contact spring 1179 springs back and the contacts SC42a1 are opened.

Means are provided to prevent contacts SC42a1 from being closed during the first cycle of a sum collection operation. rr, 24— - ON one of the arms of the oats 1047 there is attached a long 1180 (fig. 42), which with its second spirit is rotatably mounted on an arm 1181, which is installably mounted on an arm 1182, which there is attached to one other of a shaft 1183 mounted in the machine frame. At the second end of the shaft 1183 a segment 1184 with three guide surfaces 1185, 1186 and 1187 is attached. a bracket 1189 supported by the plate 764 and which is moved clockwise by a spring 1190 which extends between the angle holder arm and a bracket 1191 which is fixed there on the plate 764.

As already mentioned, the sea arm 1047 is turned slightly clockwise, as the sum lever 755 is moved to something by the sum collection laws. This movement is passed through the line 1180, annulus 1181 and the shaft 1183 for installation of the segment 1184 so that its highest surface 1186 abuts with the pin 1188 on the angle lever 1173. In this movement the angle lever is turned counterclockwise and thereby adjusted through the pin 1172 and the slot 1174 the rod 1169 to the right of the layer, in which it is partly shown by broken lines in Fig. 42.

Since the rod 1169 is in the layer indicated by dashed lines, it is no longer in the path of movement of the pin 1167 and will therefore not be moved upwards and close the contacts SC42a1 during the first machine cycle in a sun take operation.

As mentioned, at the end of the first machine cycle, in a sum collection operation, the sea arm 1047 is supplied with an additional movement clockwise. Delta causes the segment 1184 through the length 1180, the arm 1181 and the shaft 1183 to be installed so that the surface 1187 abuts the pin 1188 on the angle lever 1173. Delta allows the angle lever to rotate clockwise by the spring 1190 to return the rod to that of Fig. 42 in solid lines showed the team. Then, in the second machine cycle, in a summing operation, the cam disc 1161 will rotate the arms 1163 and 1166 counterclockwise, so that the contacts SC42a1 are closed a certain lid.

At the end of the second machine cycle in a sum-picking operation, a hay arm 1047 is rotated counterclockwise, so that the Hirt set the return lever to the Idget shown in Fig. 42. In this case, the segment 1184 is rotated so that the surface 1185 once again abuts the pin 1188 and leaves the lower end of the rod 1169 of the pin 1167 in the end of a sum-taking operation.

Means for controlling the locking switch of the unloading device.

Means controlled by the cash register operation are provided to actuate a set of contacts which block the unloading device at convenient times.

The tangent row 793 carried an arm 1196 (Fig. 37), at which one other is rotatably mounted on a long 1197. The link 1197 is rotatably joined by its second dude to a clutch release segment 1198, which is mounted on a pin 1199 attached to the machine frame. 1198 is affected by the clockwise rotation of the key laser row 793 and triggers the machine clutch mechanism on the edge and thereby initiates a machine cycle.

Menai). The 1197 points of the link there are fixed with a head-provided pin 1200, which is arranged to co-operate with a slot in one end of a line 1202, which is slidably arranged by means of two pins 1203 arranged in the machine frame, which co-operate with corresponding slots in the line 1202. Rotatable mounted on the second end of the lane 1202 is a hay arm 1204, which is rotatably mounted on a bracket 1205 supported by the plate 764. An extension 1206 which can be installed at the sea arm 1204 is provided with a roller 1207, which cooperates with a contact spring 1208 on a set normally closed contacts SC60b1 on plate 764.

When the key laser row 793 is rotated clockwise at the beginning of the usual cycle, the pin 1200 on the Milken 1197 is brought into cooperation with the slot 1201 to move the link 1202. paverkar kontaktfjaciern 1208, sa. that the contacts SC60b1 are opened and prevent the unloading device from being affected during the cash register operation.

Thereafter, the key laser row is returned under the machine key to the output layer, whereby the arm 1196, the lane 1197, the lane 1202, the sea arm 1204 and the extension 1206 are returned to the layers shown in Fig. 37 and thus can. kOrltaktfjfidern 1208 aterfjadra, so that the contacts SC60b1 Ater can be closed.

Machine release mechanism.

Means are available to release the cash register for operation and these means are affected either manually or electrically.

As already mentioned, the cash register for operation is released by turning the key laser row 793 (Figs. 37 and 41) clockwise, which movement is transmitted by means of the link 1197 to the clutch release segment 1198.

The key laser row 793 is pressed by means of a spring clockwise on the edge set and is retained against movement clockwise by the interaction between a flat pin 1215 (Fig. 41), which is mounted on a fixed arm 1216 fixed on the key laser row 793 and the end face of a conversion latch 1217, which is rotatably mounted. on a shaft 1218 supported by the machine frame.

A slot 1219 in the latch 1217 encloses a pin 1220 on a tongue 1221, which is slidably arranged by means of two pins 1222, which are fixed in the machine frame and which cooperate with corresponding slots in the tongue. A spring 1223 extending between one of the pins 1222 and a pin 1224 ph. lanken 1221 for lanken at vanster. A slot 1225 in the right direction of the lane 1221 receives a pin 1226 on one arm of an angle holder 1227, which angle holder arm is rotatably mounted on a bracket 1228 arranged on the plate 764. and is carried against said lower end of a spring 1231 between the pin 1232 and a pin 1233 on the link 1230. The link 1230 is rotatably connected to a actuating member 1234 on an electromagnet L10 fixed to the plate 764. The above-described connection between the link 1230 and the angle holder arm 1227 allows a certain deadlift to have the magnet-controlled member 1234 before it is subjected to full load, whereby the required magnetic force can be reduced.

The magnetization of the magnet L40, as will be fully described in connection with Figs. 43A-43F, causes the actuating member 1234 to be lowered, as shown in Fig. 41. This movement is transmitted through the link 1230, the angle lever 1227 and the link 1221 to the latch 1217. , so that this is turned counterclockwise and thereby the end face of the latch is removed from the blocking layer with the pin 1215. Then the pin 1215 moves below the ridge 1217 of the latch 12, so that the key laser row 793 can be actuated by the associated spring to initiate a machine operation.

Circuits.

The electrical circuits required for coordinating the operations of the cash register, unloading device and recorder are shown in Figs. 43A-43F. In these figures, certain switches which are identical to other switches, such as the differential-controlled switches SR44a1-SR46al, have been omitted, since their mode of operation is the same as the mode of operation of the switch or switches shown and can thus be clarified by describing the switches shown.

It is convenient to describe the circuits as they function in the preparation of plant flakes for surgery and in the performance of typical operations. It is assumed that the cash register, the unloading device and the recording device are in the initial law and are ready to receive information in the event of a new transaction.

First, the main power switch 125 (Fig. 1) closes on the case of the cash register. Actuation of the main power switch 125 causes the contacts ST40a1 and ST40a2 (Fig. 43A) to close and connect the cash register motor 1300, the unloading device motor 333 (Fig. 43B), the recording device motor 601 and the rectifier 598 to the night shift voltage. From the rectifier 598, DC leads 1304 and 1305 are drawn to the control circuits.

When voltage is supplied by the action of the main switch 125 and thus the contacts ST40a1 and ST40a2 of this switch are closed, a lamp 674 is immediately lit on the recording device, thereby indicating that the recording device is ready and that voltage has been applied.

Pushing of voltage ph the conductors 1304 and 1305 from the rectifier 598 causes the relay K3 to turn on. of joint monsters. When the relay K3 is switched on, the relay contacts K3b1 are opened (Fig. 43B), so that the circuit of the motors 333 and 601 of the unloading device and the recording device is broken. During the magnetization of the relay K3, the contacts K3aell (Fig. 43D) are closed and the unloading and recording device is prepared for operation, when this is to take place, and the contacts K3bell (Fig. 43e) are opened, which are located in the relay K1 detection operation. The K3be11 connectors have no special function at this time. During the magnetization of the relay I (3), the contacts K3b2 (Fig. 43C) are also opened in the circuits of the coupling magnets L9A and L9B for the punches.

In order for the strip to be able to be used together with existing electronic shavers, other card punching equipment or other data processing apparatus, it is required that the accustomed pit strip be provided with a «conductor». These strip parts are provided either with a plurality of perforations, which form a special joint sample or input code, or only with a feed hall, the feeding of which is controlled by suitable salt by pressing a button PB1 (Fig. 43C) for joint samples.

As already described, there are two coding panels 1311 and 1315 (Fig. 43F), which are mounted with the backs facing each other on a stand 732 and form the coding unit. 609. Each coding panel is arranged as a matrix with eight columns and ten rows and with a holder or base at the usual intersection point for a diode. The coding of numbers and symbols is done by inserting diodes into the sockets on the steering wheel. A diode inserted in one of these sockets completes an electrical circuit between the row belonging to the socket and the koi. Diodes are used in these circuits ph because they only conduct current in one direction. Without diodes, back-current circuits would make it impossible to electrically isolate the various number rows, symbol rows and punch selection magnets from each other, unless non-individual circuits are used in the recording plant for each perforation required during a punching cycle. In connection with the matrices there is also a row with seven connections, for example the connections 1308, 1309 and 1310 on the upper part of the had diode panels. These connections can be connected for special coding, fire as required.

Debit transaction.

After the joint sample has been stopped, the recording facility is ready to record a transaction. As an example, it is assumed that the described transaction involves a debit, that a single item occurs, that cards are used to identify clerk and customer and that a card is used for the item description and finally it is assumed that the selector switch 518 (Fig. 22), with its approaches or levels of contacts SS20a1-SS20a7 are located in the first layer.

Since it is a debit transaction, the "Debit" key is pressed in line 9 of the cash register, whereby contacts SC61a1 (Fig. 43B) and contacts SC47ac1 (Fig. 43C) are closed and contacts SC47bc1 (Fig. 43C) are opened.

A card for identification of the clerk was then inserted into the unloading device for recording by punching the strip of the identity of the clerk responsible for the transaction. Upon insertion of the card, the contacts SC23a1 (Fig. 43B) are closed, whereby a circuit is completed from the conductor 1304 to the magnet L20. ) SC23a1, SC37b1, the fuse contacts 1326, which are arranged to be opened in the event that the electromagnet L20 should burn probes, the magnet L20, the contacts SC61a1, which sin-fits at the depressing of the "Charging" key in row 9 and the normally closed contacts The contacts SC60b1 are opened at the rotation of the key laser row 793 to prevent the unloading device from operating during the cash register operation. Fig. 43A) in the starting circuit for the cash register is opened and that the alignment pins are moved forward and intervene in the corresponding direction shal in the clerk card. If the card has been properly inserted in the unloading device, the alignment pins will pass through the opening in the card and cause the IR contacts SC2Obc1 (Fig. 43B), in a circuit to the unloading device coupling magnets L22A and L22B, to be opened and the contacts SC2Oac1 (Fig. 43G) to be closed, thereby closing the magnet L21 (Fig. 43C) is supplied with voltage, through which the clamp block 181 (Fig. 6) is actuated and clamps the clerk card, said. that this Mlles steadily in lage. As already mentioned, the arm 414 is released during the magnetization of the magnet L21 by a link system, which is formed by the sea arm. 292 (Fig. 21), lengths. 308 and the link 416 between the magnet and the arm 414, thereby releasing the four sensing wires or pins which control the contacts SC25a1, SC26a1, SC27a1, SC28a1 and SC29a1 (Fig. 43B).

Upon magnetization of the magnet L21, the contacts L2lac1 (Fig. 43B) are closed and complete a circuit Over the contacts L21ac1, SP24b1, SC21b1, SS20a2 (layer 1), SC23a1, SC37b1, the fuse contacts 1326, the magnet L20, the contacts SC61a1 and the contacts L60220 The contacts L21bc1 (Fig. 43c) are opened, whereby the relay K3 is demagnetized. Then the contacts K3b1 (Fig. 43B) are closed, so that voltage is supplied to the motors 333 and 601, then the contacts K3ac11 (Fig. 43D) are opened and the original magnetizing circuit is broken to the magnet L20, which is now kept magnetized over the contacts L2lac1. In addition, the contacts K3b2 (Fig. 43C) are closed and a magnetizing circuit for the punching magnets L9A and L9B is prepared.

To start the unloading device, the "Debit" key must therefore have been activated, the clerk's card must have been inserted correctly in the unloading device and the card must be provided with a slide in the "clerk's team" in the identification section. DS corresponding to the sensing pin or wire passing through this hall, the contacts SC25a1 are closed and complete a circuit for magnetizing the coupling magnets L22a and L2213. 'age, saint contacts SC35b2. The contacts SC3.5b2 are closed to complete a shunt circuit over a resistor 1317 at 2000 ohms, whereby a high excitation voltage is obtained for the magnets L22A and L22B.

If the card is incorrectly inserted in the unloading device, the scanning pin for the contacts SC25a1 cannot move forward, since no slippery surface lies in front of the line in the identification part of the card. Consequently, the contacts SC25a1 will not be closed and the magnets will not be actuated to start a reading process. Means, which will be described below, are arranged to release an incorrectly inserted card under the control of a push button 490 (Fig. 1).

Assuming that a real card has been inserted in the unloading device and that the contacts SC25a1 have been closed and completed a magnetizing circuit to the magnets L22A and L22B, the coupling will interconnect the core. The row with the engine of the unloader. SA.- as already mentioned, the coupling for interconnection in the cam row with the motor 333 is of the single-speed type and is connected by means of the magnets L22A and L22B, so that the cam row is rotated by the motor. When this clutch revolution is completed, the clutch and release chamber are disconnected from the motor, unless the magnets L22A and L22B are magnetized a second time. As described above, no unloading operation takes place at the first vary of the chamber row after insertion into a card, since this variation has been added only so that the various components of the unloading device can take the steering wheel to unload the card.

During the first variation of the coupling, the chamber row in the discharge device travels from the starting layer to its first layer. While the contacts SC33b1 remain closed in the saval output layer, as the first layer of the chamber row, the circuit of the magnets L22A and L22B will remain closed, so that the coupling performs a second vary and interconnects the chamber row with the motor, thereby providing the chamber row a second vary.

During this second variation, the chamber row is moved from layer 1 to layer 2 and a symbol is punched on the strip to identify the type of card. Punching of this symbol can be performed by one or both of two different means, depending on the type of breathing of the recording equipment. Usually only one of these means for punching a card identification symbol on the record strip and the other means can be used for other purposes. This second means can, for example, be used for punching special additional symbols at desired times during the loading of the card. These additional symbols can, for example, form intermediate recovery signals in systems for transferring the strip values to cards. One of these means may, if desired, be used for punching an "end of the block" symbol on the strip, while the other may be used for punching a card identification symbol or for any other purpose, if the card identification symbol is not present.

One of the means for punching a card identification symbol in the strip comprises the contacts SC34a1 (Fig. 43F), which are closed approximately 15 degrees before the end of the first unloading device of the coupling. Through these contacts in contact T1 with the contacts SC35a1 (Fig. 43F), which are closed between 5 and 130 degrees of the connection of the coupling, voltage is supplied to the contact arm of the contacts SS20a6 (Fig. 43F). At this time during the transaction, the contact arm is in position 1 and the circuit therefore passes over the corresponding conductor in a cable 1318 to a terminal 1319 in a section 1320 in the selection panel 748 (Fig. 43D). A loose connection conductor, plug connection, can then be connected between this socket and a desired socket in the number or symbol sections 889 or 1321 of the panel 748, so that a circuit is closed to one. or more of the punch selection magnets PS1 — PS8 for punching the lighted identification symbol for the clerk card. As an example, a plug connection 1322 (Fig. 43D) is shown, which connects the terminal 1319 to a terminal 1323 in a symbol section 1321 in the panel 748. A corresponding conductor in the cable 1325 connects the terminal 1323 to row 2 in the symbol coding panel 1311 (Fig. 43F). A diode is displayed, which connects this line with a conductor, which in turn is connected to the punch selection magnet PS8. Magnetization of the punch selection magnet PS8 in the indicated circuit causes the corresponding punch leveling arm to close the contacts SC3a1 (Fig. 13C), which closes a circuit from the conductor 1304 to the punch coupling magnets L9A and L9B. magnetized. The punching connection thus connects the motor 601 of the recording device to the punching chambers, so that a punching cycle, for punching a hl in channel 8 on the recording strip for identification on the clerk's card, is started.

The second means for having means available for punching a card identification symbol in the record strip comprises the identification contacts SC25a2, SC26a2, SC27a2, SC28a2 and SC29a2 (Fig. 43F). These contacts are under the cooperative control of the remote sensing pins, which guide the contacts SC25a1 — SC29a1 (Fig. 43B) and of the installable cam 357 (Fig. 15) on the chamber of the unloader. If the flake on the contacts SC25a2— SC29a2 is to be closed, the corresponding sensing pin must therefore be able to move through a hall in the card to be unloaded, opposite the said sensing pin, and the forward part of the cam disc 357 must affect the contacts SC25a2— SC29a2 pa.- effecting means. It can be seen that the cam plate 357 can be installed on the cam row 359, so that the above-mentioned part affects the payer means for the contacts at any desired time during the unloading operation. In order to assume that the actuating mode of action is assumed, the cam plate 357 is so set on the chamber of the unloading device that the lamp contact in the contacts SC25a2 - SC29a2 is closed to initiate punching of an identification symbol during the second change of the coupling.

During the described operation, in which a clerk's card is inserted into the unloading device, the contacts SC25a2 are therefore closed. These contacts cause, in conjunction with the contacts SC35a1 (Fig. 43F), which, as already mentioned, draw closed between 5 and 130 degrees of the connection value, that voltage, Over a 28 - - corresponding conductor h a cable 1327, is supplied to a socket 1328 in a section 1329 on the selection panel 748 (Fig. 43D). A plug connection can connect this socket to any desired socket in the number or symbol section of panel 748, to connect a circuit to one or more of the punch selection magnets PS1-PS8, and to punch a suitable identification symbol for the clerk card. In order to damage the means which cause punching of a clerk card identification symbol, a connection conductor 1330 is used in the place of the connection conductor 1322, which is shown connecting the socket 1328 in the section 1329 to the socket 1323 in the symbol section 1324 of the panel 748. the cable 1325 with line 2 in the coding panel 1311 (Fig. 43F) and a diode can be used to connect this line to a conductor, which in turn is connected to the punch selection magnet PS8. Magnetization of the magnet PS8 in the described circuit, means that a slide is punched in channel 8 on the recording strip for identification of the clerk card, as previously stated.

After the second turn has been palorized, the contacts SC33b1 (Fig. 43B) are opened, which are closed in the output layer and first layer of the chamber row in the unloading device, and the contacts SC33a3 (Fig. 43B) are closed, which are opened in the output layer and the first layer of the chamber row. The contacts SC4ac1 (Fig. 43B), which are arranged on the chamber of the recording device, are closed between 215 and 310 degrees of the punching cycle and are thus closed at the end of the acute punching operation. Above the contacts SC4ac1 and the now closed contacts SC33a3 (Fig. 43B) a circuit of the coupling magnets L22A and L22B in the unloading device is completed, so that the coupling performs a third coupling revolution. This third variation and the following turns cause the chamber of the unloading device to be rotated, so that successive cam discs on the chamber row release their associated sets of scanning pins for unloading successive columns on the card. The sharks in each column of the card allow the corresponding sensing pins to move forward and close the corresponding contact of the contacts SC36a1 — SC36a5 (Fig. 43F). Since the contacts SC35a1 (Fig. 43F) are closed by four degrees of rotation of the coupling in the holding device, the conductor 1304 is completed from the contacts SC35a1,1 conductor 1305, the one of the contacts SC36a1 — SC36a5, which is closed, and the corresponding conductor in a cable 1335. section 1315 of the coding panel 1315. Loose connecting conductors, plug connections, are used to connect these sockets to sockets connected to the conductors in the cable, which conductors in the cable are in turn connected to the punch selection magnets PS1 — PS8. The connecting conductor 1337 of Fig. 13F, which joins the terminals 1338 and 1339, is shown as an example of such loose connecting conductors or plug connections. As already stated, the magnetization of the selected punch selection magnet in the described circuit means that the corresponding punch selection arm closes the contacts SC3a1 (Fig. 43C) and completes a circuit from the conductor 1304 to the punch coupling magnets L9A and L9B over the contacts SS1b21 and Kl1b1 SC1b21, Kl1b1B1, Kl1b1 and Kl1. Then a punching cycle is started and when the punching mechanism has reached 215 degrees, the contacts SC4ac1 are closed (Fig. 43B) and complete a circuit for magnetizing the coupling magnets L22A and L22B in the unloading device, so that the clutch in the unloading device performs a further operation cycle.

The cam discs in the unloading device are designed so that the part of each cam disc which causes the scanning pins for the figure to be unloaded is rotated to this pin release position just before the end of a previous change of the unloading device coupling, so that the contacts SC35a1 are closed. and complete the circuit at the beginning of the switching condition during which the number is read. Since each coupling revolution is drilled by completing the circuit of the coupling magnets L22A and L22B across the contacts SC4ac1 (Fig. 43B) on the chamber of the recording device, each subsequent unloading operation must be familiar with this recording of the previous unloading operation. This unloading process proceeds until all the information on the card has been unloaded by the unloading device and is recorded by the recording device.

After the unloading of a card is completed, a recovery operation is performed to turn the chamber row in the unloading device back to the output layer, as a preparation for a subsequent operation. The recovery operation is initiated by opening the "end of card" contacts for the unloaded card. In f6- religgandc case Or it is a clerk card, which is unloaded, for which the contacts SC21b1 (fig 43B) for this card type are opened. "End of card" - the contacts are placed on the square of the unloading device and arranged to be opened at a certain time during the unloading operation, which time depends on the length of the unloaded card. When the contacts SC21b1 are opened, the circuit of the magnet L20 is broken, whereby the magnet is demagnetized. This causes the alignment pins to be retracted from the alignment tail of the dispatch card, so that the card can be slid out of the unloader. When the alignment pins are retracted, the contacts SC2.0ac1 (Fig. 43C) are also opened and the contacts SC2Obc1 (Fig. 43B) are closed. Yes. when the contacts SC2Oac1 are opened, the circuit to the magnet L21 is broken, whereby this de-energizes. netiseras. Demagnetization of the magnet L21. i90823 —29 1 means that the contacts L2lac1 (Fig. 43B) in a magnetizing circuit for the magnet L20 are opened until the contacts L21bc1 (Fig. 43C) are closed.

When the contacts SC4ac1 (Fig. 43B) are closed at the end of the operation in which punching of the last digit or the arrow ball slides, a magnetizing circuit to the magnets L22A and L2213 is completed. , which are closed towers in the output layer and first layer of the chamber of the chamber in the unloading device as well as the over contacts SC35b2. When these magnets have been magnetized, the contacts L22a1 are closed (Fig. 43B). The contacts together with the now closed contacts SC2Obc1 and the contacts SC33a3 complete a tilting circuit to the magnets L22A and L22B to keep these magnets in a magnetized state, after the contacts SC4ac1 are opened, when the punch melianism of the recording device completes its operation cycle, that the motor and the cam row in the unloading device remain connected until the cam row has been moved to its thirty-sixth position. During the thirty-sixth shift of the clutch, the contacts SC33a3 are opened, which, as nanints, Oro Open in the output layer and first layer of the cam row, whereby the magnets L22A and L2213 are demagnetized and the unloading device coupler releases the cam from the motor Yid at the end of the thirty-sixth rotation. During the demagnetization of the magnets L22A and L22B, the live contacts L22a1 are opened. In order to obtain a certain operating sequence during the recording process, the envelope selector 518 (Fig. 22) must be installed in a following layer after the unloading of the clerk card. During the recording of the data from the clerk's card, the contacts SC33a4 (Fig. 43C), which were open only in the chamber row in the output layer and first layer of the unloader, when they were closed, formed a circuit for magnetizing the selector magnet SS20 over the contacts SC20aC1 (Fig. 43C), which slotos, as the alignment pins slide into the alignment hole in the clerk card, the contacts SC33a4, the normally closed contacts SC46bc1 and the contacts SS20a5 (layer 1). The DO magnet L20 was demagnetized by completion of the clerk card reading and caused the contacts SC20ael to be up-nudged, breaking the circuit to the magnet SS20 for the follower switch. The follower switch or selector 518 (Fig. 22), the attachments ay contacts SS20a1 — SS20a7 shown in the present embodiment, Or ay the type which is advanced to a following layer when its magnet is demagnetized. The demagnetization of the magnet SS20 causes the selector switch to advance to a following position, in this case Or position 2.

In the following description of the next step in the sequence of operations Or a customer card in the unloading device so that a recording of the customer room in the transaction should take place on the strip. When a customer card is inserted, the lion beats SC23a1 (Fig. 43B) are closed, whereby a circuit is completed from the conductor 1304 to the magnet L20 (Fig. 43B). "End of customer" contacts SC22b1, which remain closed until customer card replacement is completed, contacts SS20a2 (layer 2), contacts SC23a1, "no repeat" contacts SC37b1, fuse contacts 1326, magnet L20, contacts closed by SC61a1, of the "Debit" key in row 9 on the cash register sand the normally closed lion rates SC60b1.

As described in connection with the unloading of the clerk card, magnetization of the magnet L20 entails that the alignment pins are moved forward and penetrate into the corresponding alignment hall in the customer card. The magnet L21 magnetisera.s then bold. to clamp the customer card and hold it securely in the correct position and to release the four identification pins which control the contacts SC25a1 — SC29a1 (Fig. 43 B). As previously described, the motors 333 and the recording device motors 333 and 601, respectively, are supplied at this time with voltage across contacts K3b1, which are stopped when contacts L21bc1 break the circuit to relay K3.

If the steering wheel is short, ie. a customer card, is inserted into the unloading device, a circuit is completed across the contacts SC26a1 (Fig. 43B), which are closed by the associated scanning pin penetrating a hall in the customer card to be aylased. The circuit extends from the conductor 1304 across the contacts SC26a1, SS20a3 (layer 2), SC33b1, which, as already at night, are closed in the output layer and layer 1 bus of the unloading device chamber and the magnets L22A and L22B for the unloading device coupling, whereby these magnets are magnetized saint disassemble the coupling, so that the motor of the unloader is connected to the cam row. Punching an identification symbol and unloading the customer card then slips on. the same salt, which has already been described in connection with the unloading ay the clerk card and continues until the aviasing ay hand card Or completely.

After unloading all the information on the customer card and punching these on the strip, a recovery operation takes place, initiated by opening the "end of the customer card" contacts SC22b1 (Fig. 43B). HarYid breaks the circuit of the magnet L20 and this magnet is demagnetized. The recovery operation then takes place on the salt, which is described in connection with the unloading of the expedition card.

In order to obtain a correct operating sequence after the debugging of the customer card, the selector switch 518 (Fig. 22) must be stepped to the subsequent layer, which has layer 3. During the unloading of the customer card, the contacts SC33a4 (Fig. 43C), which were open only in the output layer and layer 1 of the chamber of the unloader, a circuit was completed. (it is recalled that since the described transaction is a debit transaction, the key "Debit" is pressed from the beginning) saint contacts SS20a5 (1fige 2) to magnetize the uncoupler magnet SS20. When the magnet L20 was demagnetized upon completion of the reading of the customer card, whereby the contacts SC2Oac1 (Fig. 43C) were opened, the circuit of the switch magnet SS20 was broken. This meant that switch 518 (Fig. 22) was advanced to subsequent layer, in some cases layer 3, in the manner already described.

During the next step in the sequence of operations, a product card is inserted into the unloading device, so that a description of the pre-sold product is punched on the strip according to the clerk and customer data values. When inserting a product card, the contacts SC23a1 (Fig. 43B) are closed, whereby a circuit is completed from the conductor. 1304 to the magnet L20 (Fig. 43B) Over the contacts K3ac11 (Fig. 43D), the conductor 1316 the contacts SP24b1 (Fig. 43B), the normally closed contacts K2Obd1, the contacts SS20a2 (layer 3), the contacts SC23a1, the contacts SC37b1, the fuse contacts 1326, the magnet L20, the contacts SC61a1, which are closed when the »Debit» key is pressed in row 9 on the cash register's keyboard saint the normally closed contacts SC60b1.

As already described in connection with the unloading of the clerk's and customer cards, magnetization of the magnet L20 means that the alignment pins are framed forward and penetrate in the corresponding hall in the product card and that the contacts SC2Oac1 are closed. The magnet L21 is magnetized over the contacts SC2Oac1 to clamp the product card and to release the four identification pins which control the contacts SC25ac1-SC29a1 (Fig. 43B). The relay 1 (3 is also demagnetized, as previously described, closing the contacts K3b1 again and applying voltage to the motors 333 and 601 of the unloading device and the recording device.

The product card can have one of three specified lengths, which have been called No. 1, No. 2 or No. 3. Each of the three card types is identified by a hall in a certain layer on the identification part of the card. Therefore, when the four identification pins are released to perform a detachment, the pin opposite the slide in an imported goods card will pass through the tail, which is characteristic of the card type and cause corresponding contacts to be made. Contacts SC27a1 are controlled by the scanning pin, which scans an identification hall in the product card with the length, called No. 1. Contacts SC28a1 are controlled by the sensing pin, which scans an identification hall in the product card with length no. -2. The contacts SC29a1 are controlled by the scanning pin, which scans an identification hail product card nand length no. 3.

If, for example, a goods card with length no. 1 is inserted into the unloading device, the contacts SC27a1 are closed, then the scanning pins, which guide the contacts SC25a1-SC29a1, are released. A circuit is completed when the contacts SC27a1, the "end of the product card" contacts SC30b1, the contacts SS20a3 (layer 3) the contacts SC33b1, which are closed in the chamber of the output device and layer 1 of the chamber, the contacts SC35b2 and the magnets L22A. and L22B, which magnets are thereby magnetized and reposition the clutch for an operating cycle, said. that the chamber of the unloading device is connected to the motor 333 of the unloading device.

At the same time as the magnets L22A and L22B are magnetized, a circuit from the conductor 1304 is completed. Fig. 43B) is closed, after which the contacts K2B relay 1 (20, said that the relay is kept magnetized.

It is recalled that when unloading the product card, the magnet L20 was originally magnetized over the contacts K3ac1 1 (Fig. 43 D), the leclar 1316, the contacts SP24b1 (Fig. 43 B), 1fi2Obd1, SS20a2 (laze 3), SC23a1, SC37b1, the magnet L20 , contacts SC61a1 and contacts SC60b1. During the excitation of the relay 1 (20, the contacts K2Obd1 are opened to break the original excitation circuit, then the contacts 1) are closed, whereby a excitation circuit to the magnet L20 is completed. Over the contacts SC27a1 and SC30b1. with the magnet L20 magnetized in this circuit, which Or the same, which is requested torn in connection riled clerk and customer cards.

In connection with the punching of an identification symbol for the product card being read, it should be noted that if the coding means, which include the contacts SS20a6 (Fig. 43F), are used, the same identification symbol will be used, regardless of which of the three possible product cards, which are used. On the other hand, if the coding means, which comprise the contacts SC25a2-SC29a2 (Fig. 43F), are used, it is possible to punch different identification symbols for different card lengths and thereby the different product cards which are unloaded can be identified.

When all information is unloaded from the product card and this information is stopped on the card, a recovery operation takes place, which is started by the "end of product card contacts", which correspond to the length of the unloaded card. As can be seen from Fig. 43B, the "end of the product card" contacts for each digit length are in series with the corresponding contacts, which are controlled by the identification pins. This meant that the "end of the product card" contacts SC30b1 for cards of the first digit length are in series with the contacts SC27a1, that the "end of the product card" contacts SC31b1 for goods cards with the third digit length are in series with the contacts SC28a1 and that "end on the goods card »contacts SC32b1 for goods cards of the third digit length are in series with the contacts SC29a1. Each of the contact sets SC30b1, SC31b1 and SC32b1 is controlled by the installation of the chamber row in the welding device and is arranged to be opened at a certain time during the rotation of the chamber row, which time depends on the determined length of each of the three product card types. When the "end of the product card" contacts, which correspond to the length of the card being read, are obtained, the circuit of the magnet L20 is broken, which is thereby demagnetized. The recovery operation is then completed, as described in connection with the unloading of the clerk card and the customer card.

Relay K20 has been added to force the use of the cash register in the recording facility after each product card reading for registration and recording of data, which belongs to the product, such as the product price. After a cash register operation has been completed, another goods card can be read, so that the transaction can include any number of goods items. When all the desired goods cards have been unloaded and the corresponding sales prices have been registered in the cash register, the sum can be deducted, whereby the switch 518 (Fig. 22) is reset to its first read, as will be described below.

Unloading of more than one goods card, without affecting the cash register, is prevented by opening the contacts K2Obd1 (Fig. 43B) during the magnetization of the relay K20. When the contacts K2Obd1 are open, the magnet L20 can not be magnetized again, after being demagnetized once after the completion of the first product card unloading. This condition persists until the relay K20 is demagnetized during the recording of data obtained from a cash register operation.

During the magnetization of the relay K20, the contacts E20be12 are also opened (Fig. 43A) and the contacts K20ac12 are closed. Fig. 43A shows that the opening of the contacts K20bc12 and the closing of the contacts K20ac12 change the circuits, so that the only key on the cash register, which when pressed entails magnetization of the changeover magnet L40 in front of the key laser row, SC58a1.

In a commodity operation on the cash register, the commodity price, or other desired data, is set on the keyboard part of the keyboard and the commodity key MDSE is pressed. At the close of the contacts SC58a1, by pressing this key, a circuit from an AC conductor 1341 is completed. contacts SC48bc1, which are controlled by the keys in lines 7 and 8 of the cash register, contacts SC58a1, which are controlled by the MDSE key ,. the contacts SC50a1, which are closed, da nagon. of the keys in row 1 are completely depressed, the magnet L10 and the contacts K1b13, which are arranged to effect a trickle reading of the recording device, when they are completed at the completion of a previous operation cycle of the recording device, to the magnet L40 (Fig. 43A) for switching the key laser row. magnet salunda magnetized. Magnetization of the magnet L40 means that the depressed keys are locked in their depressed layers and that the contacts SC41a1 (Fig. 43A) are closed by mechanical action. the completion of an actuating circuit to the motor 1300 in the cash register Over the said motor speed control contacts SC40b1 and the contacts SC41a1, whereby the cash register is caused to perform an operation cycle.

At a predetermined time during the cash register operation cycle after all the selector switches corresponding to the various key banks and other mechanisms have been installed correctly, a mechanism in the cash register "starts recording" contacts SC42a1 (Fig. 43D) closes to start a recording operation for recording data. control of the cash register. At the end of the contacts SC42a1 a circuit is completed. frail conductor 1304 Over one or both of the had parallel connected contacts K3acl 1 (Fig. 43D) and K2022, which are closed at this time, the normally closed contacts • SC44b1, which are controlled by the sum lever on the cash register and the contacts SC42a1 to the contact arm on the program switch SR41a2 (Fig. 43D) for row 1.

Each of the switches SR41a2 tb 32 - - contacts, representing the ten different key layers in row 1, is connected by means of a conductor in a cable 1342 to a program selection section 891 on the cash register selection panel 748.

In the context of the present embodiment of the invention using the cash register, the key in the eighth layer in row 1 is the commodity key, and as an example it can be assumed that socket 8 in section 891 of the selection panel 748 is by means of a plug connection, which in Fig. 43D is anticipated by the dash-dotted line 1344, connected to a socket for program I in section 1345 of the panel 748 for selecting the first punching program for punching goods data. The socket in section 1345 is in turn connected via a conductor in a cable 1346 to the switch's SSI (Fig. 43E) contact arm, which switch is litgOres of level. I in the step selector 726. Further assume that the contact arm of the switch SR41a2 (Fig. 431)) is instantaneously differentiated in contact position 8 during a cash register operation, in which the "BE" key is pressed. After the SSI contact arm of the selector is connected to the socket 1347 at the beginning of a recording operation, the above-described circuit of the contact arm in the step selector level SSI will continue across the socket 1347, the conductor 1348 and the normally closed contacts K1bd11 (Fig. 43D) for magnetizing the relay K1 ( Fig. 43C).

It is obvious that the connection method described above is only an example of possible programming of the recording system. If desired, plug connections can be made between any sockets in section 891, which correspond to the contacts switch SR41a2, to a socket in section 1345, which is connected to the desired level of levels SSI, SSII, SSIII or SSIV in step selector 726.

Relay K1 (Fig. 43C) is magnetized in the previously described circuit with the following result.

The contacts Klad11 (fig. 43C) are closed and complete a tilting circuit to the relay K1 Over the contacts K2b12 and the conductor 1304.

Contacts 1 {1b12 (Fig. 43C) are opened for demagnetization of relay K3. This means that the contacts K3b1 (Fig. 43B) are closed and complete a circuit to the motor 333 of the unloading device and the motor 601 of the recording device.

The opening of the contacts K1b12 (Fig. 43C) awn prevents an operation for driving the lead sample, by breaking the circuit of the contacts SP1ac1.

Contacts K1bc2 (Fig. 43C) are opened for breaking the circuit Above contacts K2bc2, which is used in conjunction with recovery operations, but not in this operation.

Contacts Klbc1 (Fig. 43C) are opened for breaking the inclination circuit to the relay K2 (Fig. 43C), which operates in joint sample paging operations. , cla the step selector 726 leaves the output layer and the relay K2 is magnetized. The voltage at connection 1308 causes unwanted articulation symbols to stop.

Contacts K1ac2 (Fig. 43C) are closed and complete a circuit from the conductor 1304 to the stepping magnet SS1 (Fig. 43C) over the contacts SS1bc21, K2bc1, Klac2 and SS1b11. When the magnet SS1 is magnetized, a spring is pulled, which drives the contact arms back on the step selector 726 and opens the contacts. SS1b11. When the contacts SS1b11 are opened, the magnet SS1 is demagnetized. This releases the drive spring of the contact arms and advances the arms to their first position.

The contacts Klac1 and K1a3 are terminated in a magnetizing circuit for the current K2, which circuit extends from the conductor 1304 Over the contacts SSlac21, Klacl, SC2b1, SS1b1 and K1a3. The contact arm of the step selector is moved from the output layer. .

Contacts K2ac2 (Fig. 43C) are closed and a full circuit of the conductor 1304 to the step selection magnet SS1 is filled, so that it is magnetized. Upon magnetization of the magnet SS1, the contacts SS1a3 (Fig. 43D) are closed and complete a circuit Over the contacts SSlac21 (Fig. 43C), K2ac2, SS1a3 and the program selector SR41a2 to the contact arm for the level SSI (Fig. 43E) in the step selector, as already described.

The device is now ready to record data in punching program I, layer 1. This data can be fixed and used in all records, which are controlled by program I or also variable data, which can be stored by the cash register and vary during different recording operations, in which programs I used.

The magnet SS1 remains magnetized until a punching operation takes place, whereby the contacts SC2b1 (Fig. 43C) are opened in the inclination circuit of the relay 1 (2).

With the step selector magnet magnetized to press voltage to the contact arm in level I, as described, therefor the circuit will continue across the contact in position 1 to a punch selection magnet.

Suppose to level. I in the step selector 726 is programmed to first record information from the cash register line 9 and then follow from the amount lines 6-2 and finally from the cash register control line 1, after which a reset operation for resetting the step selector 726 contact arm to the output layer is started. In a commodity operation, rows 7 and 8 are classification rows and are not used when the commodity card is read, since the card contains the information that would otherwise be entered by means of rows 7 and 8.

Since the first punching operation in program I is used to record information from the cash register control line 9, socket 1 for program I in the upper program panel 734 (Fig. 43E) is connected by a plug connection, which in Fig. 43E is indicated by a dashed line. 1356, to a reading socket 1357 for row 9 in the reading section 735 of the lower program panel 733. The socket is connected to a conductor in a cable 1360, which conductor is in turn connected to the contact arm of the cash register readout switch SR49a1 (Fig. 43D), as an instance corresponding to the pressed key in line 9 of the cash register.

Since in the selected example the Debit »key in layer 8 in row 9 is pressed, in a cash register operation the oncoupler SR49a1 has a mechanical instant with its contact arm on contact 8.

The contacts of the switch SR49a1 are connected to the corresponding sockets in section 892 of the cash register selection panel 748, with conductors in a cable 1362. These sockets can be connected by plug connections to sockets in the panel 748's numerical section 889, which section above the corresponding numerical conductor in a cable 1364 to the input conductor of the numerical coding panel 1315 or to the sockets in the symbol section 1324, which are connected via conductors in the cable 1325 to the input conductor of the symbol coding panel 1311.

As an example, suppose that socket 8 in a section 892 of panel 748 (Fig. 43D), which socket belongs to the selector SR49a1, is connected by means of a plug connection, which in Fig. 43D is indicated by the broken line 1365, with a socket 1366 in the panel 748 symbol section 1324. With the selector SR49a1 contact arm in position 8, then a circuit to the contact arm frail a step selector socket Over a conductor in the cable 1360 will go Over the selector SR49a1 to socket 8 in section 892, thence Over a plug connection 1365, a socket 1366, a conductor in the cable 1325, input symbol conductor 3 (not shown) for the symbol coding panel 1311 (Fig. 43F) and diodes in the selected rows on the coding panel 1311 for corresponding punching magnets, for punching in selected channels on the strip. The completion of the circuits of these magnets starts a punching cycle, in which case a symbol represented by slippery in the selected channel channels is punched.

During the punching of the strip, the contacts SC2b1 (Fig. 43C) are opened for demagnetizing the relay K2, which in turn opens the contacts K2ac2 (Fig. 43C) for demagnetizing the step selection magnet SS1 and advancing the contact arms to position 2. Demagnetization of the step selection magnet SS1 contacts SS1a3 (fig. 43D) Open and break the circuit Over the contact arm of the step selector, where the contact arm goes from position 1 to position 2. This eliminates spark formation between the contact arm and the contact during movement from contact to contact.

At 185 degrees of the punching cycle, the contacts SC2b1 for magnetizing the relay K2 and the step selector magnet SS1 are closed again, which in turn closes the contacts SS1a3 to complete a circuit Over the step selector arm in level I and position 2 in the step selector 726.

In accordance with that for niva. In the set-up program, information from the cash register's amount line 6 must then be recorded. When program I is set up in the recording device, a plug connection, which in Fig. 43E is represented by a dashed line 1367, must be connected between socket 2 for program II program panel 734 and a unloading socket 1368 for row 6 in the unloading section 735 of program panel 733. The socket 1368 is connected to a conductor in the cable 1360, which conductor is in turn connected to the contact arm of the cash register unloading switch SR46a1 (not shown), which is installed corresponding to the number entered on line 6 in the cash register.

For example, suppose that key 3 in row 6 is pressed. In a cash register operation, the unloading switch SR46a1 will then be mechanically installed with its contact arm on contact 3.

As shown in Fig. 43D, the corresponding number contacts in each of the readout switches SR42a1 — SR48a1, corresponding to rows 2-8 of the cash register, are interconnected by conductors in the cable 1364, which conductors continue to the corresponding number rows on the digit coding panel 1315 (Fig. 43F). . Since the switch SR46a1 is installed in layer 3, its receiver will complete a circuit from terminal 2 in program I Over conductor 1367, terminal 13158, associated conductor in cable 1360, cash register unloading switch SR46a1 and conductor "3" in cable 1364 to the input digit conductor. shown) in the numeric coding panel. 11315. Diodes are inserted to connect input conductor 3 to some of the punch selection magnets PS1 — PS8 (Fig. 43F) in accordance with the desired coding. The completion of the circuits of these magnets means that the associated punches are selected and that a staring cycle is started, during which the number 3 is punched in the strip by perforating corresponding strip channels by the selected punches.

During the second punching cycle of the program, the contacts SC2b1 (Fig. 43C) are opened again for deimagnetization of the relay K2 and the stepping magnet, so that the contact arms are advanced to age 3 and at 185 degrees of the punching cycle the re-contacts SC2b1 are closed , which closes the contacts SS1a3 and completes the circuit over the socket 3 in program I in the program panel 734 and over a plug connection to a socket in the panel 733 section 735 and the corresponding conductor in the cable 1360 to the switch SR45a1 (not shown) contact arm, for recording the information from the cash register amount line 5. During the punching of the third digit, the contact arms are moved to position 4.

On the same salt, as described above, the information from the different unloading switches SR44a1 — SR42al is recorded, which corresponds to the amount lines 4-2 on the cash register.

After completion of information recording from the amount lines 62, it is requested to record information from the cash register control line 1. DA program I must be set up in the recording device, a plug connection, which in Fig. 43E is represented by a dotted line 1369, must be connected between sockets 9 for program I in the program panel 734 and a unloading socket 1370 have row 1 in the unloading section 735 of the panel 733. The socket 1370 is connected to a conductor in the cable 1360, which conductor in turn is connected to the contact arm in the unloading switch SR41a1 (Fig. 43D). which switch in the present case is capable of position 8, since the "BE" key is pressed in this row.

Since the switch SR41a1 is installed in position 8, its contact arm completes a circuit from socket 9 for program I Over the plug connection 1369, socket 1370, corresponding conductor in cable 1360, switch SR41a1 and 8-conductor in cable 1371 to corresponding socket number and symbol section 890 in the panel. 748 (Fig. 43D). Delta sockets Or by means of plug connections connected to sockets in the number section 889 of the panel 748, which are connected to the corresponding numerical conductor in a cable 1364 with input conductors in the numerical coding panel 1315 or also the former sockets are connected to sockets in the symbol section 1324. input conductor in the symbol coding panel 1311. These plug connections can be made on the same salt as the previously described connections for recording information from the cash register control line 9. DA. the switch arm of the switch SR4la1 is in position 8, a circuit to the selected input conductors in the symbol coding panel or numeric coding panel and Over diode connections to selected punch magnets for starting the punching cycle are completed, a symbol or number represented by hal in corresponding stripe channels.

After all the information read from lines 9 and 6-1 on the cash register has been recorded, it is necessary that the contact arms of the step selector 726 be returned to their initial layers. The necessary program control to provide participant accesses a plug connection for each program, which connects the reset sockets 739 for each program to the socket immediately after the socket used in recording the last data of each program. Such a plug connection is represented, for example, in Fig. 43E by a dashed line 1374, which connects a reset socket 739 to a socket 1375 for program I in the program panel 734. The socket 1375 is assumed to be the socket immediately following that which records the recording of the last recorded values in program I. When the contact arm in the step I 726 level I is advanced to a contact connected to the socket 1375, a circuit Over level I, the socket 1375, the plug connection 1374, the reset socket 739 and a conductor 1376 to the relay K3 Over the contacts K2a13 are completed (fig. 43C). These contacts are closed, the old fire K2 is magnetized and causes the fire K3 to be magnetized. When the fire K3 is magnetized, the contacts K3bell are opened for demagnetization of the fire K1, because the contacts K2b12 Oro Open at this time. Contacts Klac1 Open salunda and break the circuit to the line K2 and the coupling magnets LOA and L9B. The contacts Klbc2 are closed and complete a circuit Over the contacts S51ac21, K2bc2, Klbc2 and SS1b11 to the stay selection magnet SS1. When the magnet SS1 is magnetized, the shear break contacts SS1b11 are opened, whereby the magnet SS1 is de-magnetized and the contact arms advance one step. When the magnet SS1 is demagnetized, the contacts SS1b11 are closed again, whereby the magnet SS1 is magnetized again.

Delmar recovery operation continues until the contact arms in the step selector reach their starting positions. At this time, the contacts SS1ac21 open the reset circuit Over the contacts K2bc2, K1bc2 and SS1b11 to the step selection magnet SS1. In the output mode of the step selector, the contacts SS1bc21 are closed. The device has now recorded all the information required in program I and the contact arms of the stay selector 726 have returned to the output layer.

Demagnetization of the line K20 for internal loading between the unloading device and the cash register follows the start of the operation for recording information entered in the cash register. It may be recalled that the initial operation of the step selector 726 causes the contacts SS1bc21 (Fig. 43C) to be opened. at the circuit frail the conductor 1304 is broken across the contacts SS1bc21, a conductor 1340, contacts R2Oadll (Fig. 43B), SS20a4 Gage 3) to the line K20, so that this raid is demagnetized.

During the demagnetization of the line K20, the contacts K2Obd1 are closed (Fig. 43B) and a further product card can be unloaded by the unloading device, if desired, upon completion of the recording of the information entered in the cash register. Contacts K2Obel2 (Fig. 43A) are also closed and now any of the "Deposit", "Discount", "Tax" or "Miscellaneous" keys in row 1 can be used, which respectively control the contacts SC42a1, SC53a1, SC57a1 and SC56a1. , to start a cash register operation, if appropriate.

It is clear that unloading of the goods cards and associated cash register operations in a transaction, which includes more than one requested item, will result in the recording of information for each item, as it has already been described when selling and recording a single item. .

The described debiting transaction is terminated by losing the sum of the transaction, which sum may contain one or more pre-sold items. The sum taking in a debiting operation also means that the tracking switch 518 (Fig. 22) is moved back to layer 1, so that it is installed for a following transaction. The mechanical construction of the cash register used in the described installation is such that the lever 756 is mechanically blocked, da. lever 755 years in addition. When the lever 755 is moved to the "sum" position, the lever 756 is released so that it can be depressed. When summing, therefore, depressing the lever 756 causes the contacts SC45a1 (Fig. 43A) to close, thereby completing a circuit Iran and an AC voltage conductor 1341 to the switching magnet L40 for the key laser row. During the magnetization of the magnet L40, the tangent laser row 793 is released, said. that it can be rotated. Rotation of the key laser row 793 in turn causes the contacts SC41a1 (Fig. 43A), which are controlled by cam discs on the key laser row, to be closed, whereby a sum collection operation is started in the cash register.

Depressing the lever 756 for a sum operation in a debit transaction on the present cash register type causes the differential mechanism for row 1 of the machine to enter the fifth layer, so that the contact arm of the program switch SR41a2 (Fig. 43D) is installed on the fifth contact, which is connected to the corresponding socket in the panel 748 (fig. 43D) section 891 Over a conductor in the cable 1342. Said socket can be connected by means of a plug connection to a socket in the program section 1345 of the panel 748, for selecting a desired level in the step selector SS1 for the sum program.

In the case of a cash register of the type used, two machine cycles are required for a sum collection operation. The switches SR42a1SR48a1 (Fig. 43D) are installed, during a sum collection operation, in accordance with the sum calculated by the cash register. The "Start Recording" contacts SC42a1 (Fig. 43D) are actuated, as mentioned, by the cash register 1036's main chamber and are slated, during a sum collection operation, only during the second machine cycle. In the present case, the contacts are arranged to be closed at 535 degrees and to be reopened at 585 degrees by the summing operation. When the contacts SC42a1 are closed, a recording cycle is started, in which information belonging to the summing operation is punched on the strip, in accordance with the programming of the selected level in the step selector SS1.

For example, it may be unwise to first record a number of specific numbers, which identify the machine used in the transaction. If four numbers or symbols are desired to be punched, the first four sockets on the Upper Program Panel 734 are connected, which correspond to the first four contacts in the selected level in the step selector 726, for example level. II, through plug connections with sockets in the number section. 738 or the symbol section 737 in the lower program panel 733. The sockets 1 in the numeric section 738 are across conductors in the cable 1364 connected to the corresponding inputs in the numeric coding panel 1315 (Fig. 43F). Sockets in the symbol section 737 aro Over conductors in the cable 1325 connected to the corresponding inputs in the symbol coding panel 1311. As a result, the lamp punch selection magnets PS1 — PS8, (let the step selector 726 be stepped through its first four layers) are magnetized, thereby punching or symbols.

It may be unreasonable to punch the sum calculated by the cash register in a sum collection operation, although this does not normally happen in the described embodiment of a recording facility. This sum is installed on the switches SR42a1 — .S.R48a1. The information displayed on these switches can be recorded, through all lamp sockets, as well as corresponding to the selected step selector level, in the upper program panel 734 by means of plug connections connected to sockets in the section 733 of the lower program panel 733. , in the same way as previously described in connection with the recording of the sale price set with the cash registers' amount keys.

The programming of a selected step selector level for a sum program is completed by connecting the appropriate step selector socket to a reset socket, as previously described. When the lever 756 is depressed, the contacts SC45a2 (Fig. 43C) are also closed to complete a circuit from the conductor 1304. At a subsequent release of the lever. 756 8 open the contacts SC45a2 and break the newly connected circuit, whereby the magnet SS20 is demagnetized, so that the switch 518 returns to position 1.

In connection with the description of a record in a debit transaction, it should be noted that a debit transaction can be carried out and recorded by the record facility described above, even if no clerk, customer or goods card is used.

As before, the transaction with the switch 518 begins in its first state and the plant is prepared for a debiting transaction by pressing the "Debit" key. Since no clerical card was used, the clerical number must be displayed on cash registers amount lines 2-8.

The "clerk number" key in row 1 is then pressed, to close, the contacts SC59a1 (Fig. 43A). This completes a circuit from the AC voltage conductor across the contacts L20b1 (Fig. 43A), SS20b14, SS20a1 (layer 1), SC59al, SC50al, the switching magnet L40 for the tangent line and the contacts K1b13 to the magnet L40, which, as mentioned, closes the contacts during the magnetization. 43A), so that the cash register is started for an operating cycle.

When the "clerk number" key is pressed, the contact arm of the program switch SR41a2 is also installed in layer 9, which, as already described, can be connected for selecting a predetermined level in the step selector 726, which is programmed to record a clerk number.

The cash register operation entails that the "Start the record" contacts SC42a1 (Fig. 43D) are closed, after which the clerk number installed on the cash register amount rows, in addition to any other desired identification symbol or information in accordance with the programming of the selected level in step selector 726, is described. .

The cash register operation also causes the contacts SC46ac1 (Fig. 43C) to be closed and the contacts SC46bc1 (Fig. 43C) to be opened. These contacts are controlled in accordance with install. the indicator segment for line 1 in the cash register, which segment is converted to the clerk number law, during a clerk number operation. When the contacts SC46ac1 are closed, a circuit frail the conductor 1304 is completed over the contacts SS20bc13, SC44b2, SC46ac1, SS20a5 (layer 1) of the magnet SS20, whereby this is magnetized. This opens the contacts SS20bc13 and the magnet SS20 is thus demagnetized, causing advancement of the switch 518 to layer 2. The opening of the contacts SC46bc1 prevents a circuit from being completed. The SS20 Ater skittle is magnetized at this time.

The rotary switch 518 will not bypass layer 2 during a clerk number operation, since the flagon circuit to the magnet SS20 over the contacts SS20a5 (layer 2) has not been completed during it. The recording facility is therefore prepared to record a customer number, after the recording of a clerk number has been completed.

To start an operation for recording customer numbers, the customer number is installed on the amount lines next to the cash register and the "customer number" key is pressed to close contacts SC54a1 (Fig. 43A). This completes a circuit across contacts L20b1, SS20b14, SS20a1 (layer 2) SC54a1, SC50a1, magnet L40 and contacts K1b13, so that magnet L40 is magnetized and starts a cash register operation cycle.

When the "customer number" key is pressed, the contact arm SR41a2 (Fig. 43D) of the program switch is installed in layer 4, which, as previously described, is connected for selecting a predetermined level in the step selector 726, which is programmed to record a customer number.

Cash register operation involves closing the "start recording" contacts SC42a1 (Fig. 43D) and recording of the customer number and other identification symbols or other requested information installed on the cash register amount rows then takes place, in accordance with the programming of the selected level in step selector 726. previously described.

Cash register operation also means that the contacts SC43a2 (Fig. 43C) are closed. These contacts are controlled in accordance with the installation of the indicator installation segment for line 1 in the cash register, which segment is installed in the customer number layer during a customer number operation. When the contacts SC43a2 are closed, a circuit is completed from the conductor 1304 Over the contacts SS20bc13, SC44b2, SC43a2, SS20a5 (layer 2) to the magnet SS20, which is magnetized. This in turn causes the contacts SS20bc13 to be opened, whereby the magnet S520 is demagnetized, so that the switch 518 goes from layer 2 to layer 3.

Cash transaction.

In the case of a cash transaction, certain components of the record facility are used, which are not used in a debit transaction. In the following description of a cash transaction, only those elements, which essentially differ from the corresponding elements in a debit transaction, will be treated in detail. It is assumed that the transaction only involves a sales object, that a card is used to identify the clerk and that a card is used for the yarn description, and finally, that the switch 518 with its sets or levels of contacts SS20al-SS20a7 is in its first layer. - Since this is a cash sale 9, in S1 4th sl ei fi sf - - 37 ning, the «Itontant» key is pressed in line 9, which, when the cash register is then started, causes the contact arms in the switches SR49a1 (Fig. 43D), SR49a2 and SR49a3 (Fig. 43A) for row 9 are installed on their ninth contacts and the contacts SC61a1 (Fig. 43B) are closed.

A clerk identification card is then inserted into the holding device and a holding and recording operation is performed on the same Ott as already described in connection with a debiting transaction.

In a debit transaction, the switch 518, as mentioned, progressed from layer 1 to ldge 2 when the unloading of the clerk card was completed. In a cash transaction, such as the one now described, the contacts SC47bc1 (Fig. 43C), which are opened during a debit transaction, when the "Debit" contact is depressed, remain closed. When the contact arm of the contacts SS20a5 reaches ldge 2, a circuit is therefore closed from the conductor 1304 over the replacement contacts SS20bc13 (Fig. 43C), the contacts SC44b2, SC47bc1, SS20a5 (layer 2) to the magnet SS20, which is magnetized. This opens the contacts SS20bc13 and the magnet SS20 is demagnetized and advances the switch 518 to ldge 3. Laze 2 is passed on delta salt in a cash transaction, since there is no reason to identify the customer.

Item data is recorded with the switch 518 in lap 3 in the same way as described in a debit transaction.

After the entry of all goods data has been completed, deposit, discount, tax or other entries can be slipped, after which a partial sum is taken in the cash register, by moving the sum lever 755 to the "same" value and depressing the motor lever, whereby the contacts SC45a1 (fig. 43A) terminates and completes a magnetization circuit to the magnet L40 to start a register operation cycle, at which the sum of all goods plus all other values, such as tax etc. is calculated and indicated by the cash register, without flagging on the strip.

Then it is entered by the customer, as payment for the amount calculated by the cash register, the overdue amount on the amount lines and a machine operation is started by pressing the "Cash amount" key in line 1. The lever 755 has automatically continued back to the "add" team at the end of the previous transaction.

When the "Receivable amount" key in row 1 is pressed, the contacts SC55a1 (Fig. 43A) are closed, whereby a circuit is completed from the AC voltage conductor 1341 over the contacts L20b1, SS20b14, SS20a1 (Idge 3) K20bc12, SR49a2 (whose contact arm is located in ld, depending on the "Cash" key in row 9 being pressed), SS55a1, SC50a1, the magnet L40 and the contacts K1b13, so that the magnet L is magnetized and starts a machine cycle, ph salt, as already described. The amount paid is entered in the cash register and is indicated and printed on appropriate recording material, but is not stamped on the strip.

To complete the cash transaction, a sum is taken, by moving the lever 755 to the «total items» ledge and by depressing the lever 756. The mechanical construction of the cash register is, as mentioned, such that the differential mechanism for row 1 goes into age 1, if the customer is to have gear back and into ldge 5, if the customer is not entitled to gear. The bill amount, or the amount owed by the customer, is tracked, indicated and printed on the receipt by the cash register. In addition, the differential mechanism for row 1 will cause rearrangement of the contact arms in the switches SR41a1 (Fig. 43D), SR11a2 (Fig. 43D) and SR41a3 (Fig. 43A) for row 1, in accordance with the installation of the said differential mechanism. Installation of the switch arm SR41a2 contact arm in ldge 1 or ldge 5 Or that voltage is applied to a selected level in the step selector 726 over the program panel 748, (Fig. 43D), for recording a sum program, as previously described. In the present embodiment of the recording facility, the selected level in the step selector 726 is usually programmed to record a series of determined numbers, which identify the machine used in the transaction and to record a reference number which identifies the transaction.

In the intended use of the described embodiment of the recording facility, the recording program for a sum operation in a cash transaction does not include recording of information from the flag of lines 1-9 in the cash register. However, the software may be arranged to include recordings of information from one or more of these lines, if desired in a particular application.

Card, release and recovery means.

When the button 490 (fig. 1) is pressed, the contacts SP24b1 are opened, whereby the circuit of the magnet L20 is broken. The circuit passes over the contacts K3ac11 (Fig. 43D), SP24b1 (Fig. 43B), SS20a2, SC23a1, SC37b1, the circuit contacts 1326, the magnet L20 and the contacts SC61a1 and SC60b1. As a result, the magnet L20 is demagnetized, so that the alignment pins of the holding device are pulled out of the card. Upon retraction of these alignment pins, the contacts SC2Oac1 are opened (Fig. 43C), whereby the magnet L21 is demagnetized, which in turn causes the card to be released, so that it can be detached from the holding device and the steering wheel card inserted for unloading. However, as soon as the unloading of the card is started, and this happens automatically, when the card is inserted in the holding device, the 38- button 490, which controls the contacts SP24b1, becomes inoperative and cannot release the card, because the magnet L20 excitation circuit shunts the contacts SP24b1 through the contacts SS20ac13 ( Fig. 43B), when the switch 518 is in position 1 or 2. The opening of the contacts SP24b1 at such a time, therefore, does not mean that the circuit of the magnet L20 is broken, since the circuit will be kept closed by the contacts SS20ac13, la.ge 1 or 2hos contacts SS20a2, contacts SC23a1, contacts SC37b1, fuse contacts 1326, magnet L20, contacts SC61a1 and contacts SC6Oh1. When the switch 518 is in position 3, the contacts SP24b1 are shunted by means of one of the circuits passed through one of the sets of sensing contacts SC27a1, SC28a1 or SC29a1 and the corresponding »end of shortb contacts SC30b1, SC31b1 or 8C32b1, the contacts K2Oad1, 3), SC23a1, SC37b1, fuse contacts 1326, magnet L20, contacts SC61a1 and contacts SC60b1.

The same pushbutton 490, which controls the contacts SP24b1, is also used to return the unloading device to the output layer, in the event that the voltage to the recording system has been lost during a previous short unloading operation, before the unloading has been completed. When the button 490 is pressed, the contacts SP24a2 are closed (Fig. 43C), whereby a circuit is closed for the switching magnets L22A and L22B. The circuit extends from the positive conductor 1304 over the contacts L21bc1 (Fig. 43C), which are closed because the card, which was to be unloaded before the voltage was broken, is ejected from the unloading device at the voltage drop, at which the magnet L21 was demagnetized, the contacts SP42a2 SC33a3 (Fig. 43B), which are closed because the chamber of the unloader is not in the output layer or layer 1, the contacts SC35b2 and the coupling magnets L22A and L22B. Magnetization of the magnets L22A and L22B in the above circuit, causing the contacts L22a1 (Fig. 43B) to close and complete a tilt circuit for the magnets L22A and L22B from the conductor 1304 over the contacts SC2Obc1 (Fig. 43B), which are closed, depending on no card is present in the unloading device, contacts L22a1, contacts Sc33a31 and contacts SC35b2. The magnets L22A and L22B remain magnetized in this circuit, even if the contacts SP24a2 are opened again by releasing the pushbutton 490. The circuit Over the contacts L22a1 to the magnets L22A and L22B remains closed, until the unloading device chamber is turned to the output layer, when the contacts SC33a3 are opened and demagnetize the magnets L22A and L22B. Restoration of the chamber of the unloading device can thus take place by pressing the button 490 after a voltage failure has interrupted the unloading of a card, which partially unloads the card and has also been ejected from the unloading device.

In order for the unloading device's chamber row to be restored, the circuit to the device's motor 333 (Fig. 43B) must be closed above the contacts K3b1 (Fig. 43B). These contacts are closed during the recovery operation, due to the relay K3 being demagnetized, since the contacts SC33b2 (Fig. 43C) in the magnetizing circuit of the real K3 are open, except when the unloading device chamber is in the output layer or layer 1, and therefore remain open until the recovery of the unloading device chamber has been completed.

Interchangeable unit for selection of the sequence.

As stated in connection with the description of the mechanical construction of the unloading device, there are some of the components of the device, for example the switch 518 (Fig. 22), the switch magnet SS20, certain contacts which are controlled by said magnet, and so on. enclosed in a unit which can be removed from the unloading device and replaced with another unit which contains components which control a different sequence of operations in the recording system.

In the embodiment of the pick-up plant shown in the circuit diagram and described above, this interchangeable plug-in unit comprises a three-layer switch 518, so that each complete transaction will comprise a clerk number operation, a customer number operation and a goods operation.

If you wish to use the recording system in a special connection, in which only two distinct operations, such as customer number and item operations, are required for each transaction, the original unit must be pulled out and a unit with a two-layer selector inserted. The sequence of operations with such a switch will be layer 1 to layer 2 and back to rage 1, whereby the sequence for two different operations of any nature is obtained.

It may also be unwise to use the recording facility in connection with, for example, an inventory, whereby each transaction comprises a single operation. The original device must be discarded and replaced with a device lit for the transaction. In this latter case, the switch can be completely omitted and the unit will mainly form a connecting means for the various wires.

It is clear that interchangeable plug-in units, three of which, as examples, described above, allow great uses for the recording system and make it possible for a single recording system to be used in a number of different contexts simply by exchanging units. 1 - -39
