Description

10 15 20 30 35 453 329 2 The second group of records on the receipt includes takes variable data that depends on the individual items in existing purchases. This includes, for example, the individual prices, product weights, meadow prices, product numbers and the like, which of course conforms to it the nature and quantity of the product in question. At the bottom of the receipt finally, the final sum for the purchase is also drawn.

The prior art device of this type requires for the completion of a receipt a double print work. All signs and symbols belonging to the said permanent pressure was applied to a cliché, as for completion of the corresponding lot of the receipt required own work mechanics. For recording of the variable data was a special printing plant with printing types or the like, which could impose the desired the numeric or alphanumeric symbols were for sig. The production of such a cliché takes a long time in demand and is relatively expensive. Change it permanent pressure requires long-term adjustment beten. Such a printing plant also takes up a lot of space and is subject to disturbances because different parts of 43) the printing works are tuned one after the other to their function- I tion .. I The object of the invention is to provide a æm fi fråmmgf av alert i m fi zentisrawezts .l imgæess nämnda slaget, which has a simple print and yet stands out through great reliability and fast adaptation to changing operating conditions. This object is achieved according to invention in that the printing plant has a single point matrix printing device for recording both the per- manenta pressure as the variable data and a removable insert in a space or pocket, that the insert holds the corresponding control program for printing it permanent pressure and an integrated coupling, in particular a programmable read only memory, and that the socket in the printing unit for the receipt section is equipped with a sensor, which constitutes a trigger means for the printing plant for 10 15 25 30 35 453 329 3 drawing of the permanent pressure on the computer feeder.

This has, first and foremost, the need for different pressure system for both the permanent pressure and the variable data is eliminated when producing one receipt. Such a matrix printing device is particularly space-saving, as it only has a collection of point-like pressure elements such as pelvis need to be arranged in blqtt a single row. So- it requires the production of a receipt the printing plant small space, so that it very well can be placed inside a shop scale. sodium printing5 ~ the device is also extremely inexpensive. The point such actuating pressure elements can produce not only alphanumeric symbols representing several elements ment and / or multiple activation of an element in successive work steps, but at the same time visible image components in the permanent print of the receipt.

You get a surprisingly large amount of freedom in the design of the permanent pressure. The entire control program for activation of the pressure elements when presenting it permanent pressure is summarized in an effort that is placed in a well-accessible space or pocket in the printing plant.

The invention also relates to a very advantageous method of arranging the means in the printing plant, which determines the shape of the permanent pressure on receipt. Namely, within the scope of the invention a particularly simple programming of said invention characteristic effort. A ' In this method according to the invention it is sufficient to use the desired permanent pressure in any model, it may be as a drawing, as a photo or as a three-dimensional object. This model photo- graphed with a video camera or similar and converted read first - with respect to a selectable reference value for the blackening in the exposed photo - to a when signal sequence. This signal sequence can then at J5EQQ _____-_ IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII 10 15 20 25 30 35 453 329 4 needs to be corrected or supplemented and on a video terminal in line presentation provide a rasterized image of the model; The number of break points per line in the said raster image corresponding to that of the number of elements in the matrix printing device. This raster image can lagras. Finally, it is queried and programmed into rates. On the video terminal, you can distinguish raster its appearance and correct this by amending the different break points or the addition of additional raster points. In this way, the permanent pressure can appearance is optimized, obtaining an impeccable action with pressure determining control program. The owner of a scale designed according to the invention can have a collection of different initiatives for different manate pressure, which he as needed by introduction of the insert in the space or pocket in the printing press can use for the production of permanent data on receipt. In this way, the appearance of the receipt with view of the permanent pressure changes in the shortest possible league time. It would even be possible to connect a joint effort over the corresponding electrical connections to a collection of independent dares, which for achieving its permanent pressure brings it out in the effort existing control program. Hereby would one for all printing plants in an entire company dares to know achieve a very quickly adaptable uniform pressure for all receipts to be issued by the road printers.

In this way, a particularly obvious relief is achieved the work.

An embodiment of the invention is incorporated herein by reference the following is described in more detail with reference to attached drawings. Fig. 1 shows one according to the invention designed price calculation scale. Pig 2 shows a section through the main parts of a according to the invention designed printing plant. Fig. 3 shows in strong disturbance and with some parts broken off a plan view of an essential detail in the printing unit used in Fig. 2. 10 15 20 25 30 35 453 329 9 Fig. 4 shows an example of one with the printing plant according to receipt produced by the invention. Fig. 5 shows in strong magnification an image of one with the printing plant according to the invention symbol produced. Fig. 6 shows as a block diagram the most important components of the one shown in Fig. 1 price-calculating wave. Pig 7 shows in a similar way the means for arranging a leaf-giving guide means.

The device shown in Fig. 1 consists of one of two-part, price-calculating scale that is combined set by a weight determination unit II and an evaluation unit 10. Both units 10, ll would also be in compact construction can be united in a common housing.

The weight determination unit occupies a product 12, the weight of which to be determined, on a load bowl 13 which affects a measuring device not shown in detail, known per se which transmits measurement signals via a connecting line 14 to the evaluation unit connected to the measuring device called 10. I The evaluation unit 10 comprises an input device order 15 which has numeric keys for entering unit and printing prices as well as various instruction keys ter. Furthermore, an indicating device 16 is provided, as both md? the seller side visible in Fig. 1 and towards the buyer side invisible in Fig. has a reading window of various kinds for visual presentation of unit price, the weight of the product and the price of goods determined via the counter set. Finally, the evaluation unit 10 also comprises a printing unit 20 as in the embodiment shown is incorporated with the housing. If necessary, the printing plant would however, may also be placed in a special, over electrical connections to the printing unit connected unit.

The printing plant 20 is there to deliver a purchased document. receipt 19, on which the data of the individual goods, such as prices and / or weights are listed. Pig 2 indicates the construction of such a printing plant according to the invention, while Fig. 4 shows an example of that of receipt issued receipt l9. 10 15 20 25 30 35 453 329 6 As shown in Fig. 4, such a receipt comprises 19 two fundamentally different sections 28, 29. The first the average is located in the head of the receipt and constitutes a which as shown may be compound a unit strip 3l and possibly manual pressure 28, of a company box 30, additional fixed tasks, In company box 30, in addition to text such as a number 32 on the device. image parts arranged, namely one an ornamental frame 36. Unit list 31 data 34 as well company emblem 35 and indicates the designations, the values of which shall be numeric indicated in columns in the underlying receipt section 29, which will be described in more detail below. In the first column, the weight information is displayed in "kilograms", in the intermediate column the unit price, ie the respective currency unit per kilo of the item and in the last column the currency unit for it the said values determined the commodity price.

In the lower section 29 of the receipt, only variable 111. ' the data. Lined up in a row, the individual items are displayed of the goods included in this purchase. In the embodiment shown in Fig. 4 the receipt includes the first three items and the fifth item goods, from which the price of goods is calculated respectively determined weight and associated unit price for the product. As a fourth item, only one unit price is displayed, because the unit price of the pre-packaged product already is determined from the beginning. At the foot of the receipt, the final the sum, which is calculated by adding those in it split existing commodity prices.

As shown in Fig. 2, used before recording both the permanent pressure 28 and the variable data 29 and receipt 19 the same printed matter, namely a matrix printing press 21. In the printing press there is one to one roll 18 wound web by a data carrier 17 which in horizontal cases are arranged to be written on thermal path. The roller 18 is located in a pressure unit arranged bowl 53. The web 17 is passed over one at an angle bent edge 22 on the bowl 53 of the die printing unit 21.

From there, the web 17 is passed past a separating edge 26 10 15 20 25 30 35 ”Üvvn / * lgs r 1 w =. ““ Û ~ - ~ »- ~ w ~ w ~ mv-» ~ »- ~ ....._..., - w- ~ W-amw, _ ._ n-, 453 329 7 through an opening 25 in a flap 23, which closes one lower housing part 24 of the printing unit 30; As shown of the dashed position shown by dashed lines the flap 23 must be opened in order to gain access to the interior of the bowl 52, for example for replacing the roller 18. Through an inspection window 27 you can check the belt supply on the roller l8. The end part of the data carrier 17 as protruding from the opening 25 in the flap 23 can be pressed towards the separating edge 26, whereby said end part is separated is cut and is useful as receipt 19 on this purchase.

This process will be described in more detail below.

The matrix printing plant 2l comprises, as shown in plan view in Fig. 2, a collection of point-like elements 33 which here are arranged in a row. Each of these elements 33 is equipped with electrical supply and discharge 37, with which the element 32 is arranged in one carrier sheet 38 of insulating material. The 33 points of the element However, similar surfaces lie free on that of Fig. 2 web 17 and can be made operative to drawing on said path, when current flows through the supply 37. The carrier sheet 38 is at the ends 37 fitted with plugs 39 hearing wires of their wires which - as shown in Fig. 2 - cooperate in assembled condition with complementary sockets 40 mounted on a conductor plate 41. arranged in the printing housing 24. the sheet 38 is flexible enough to bend in the form shown in Fig. 2. The area of the carrier sheet 38, is pressed against a roller 44 by a pivotally arranged device comprising said thermally active element 33, pressing means 42 which are under the action of a spring 43. The roller 44 is provided with a drive (not shown). device, which provides for a specific transport of path 17 corresponding to the thermal 33 of the elements 33 Averkan. The elements 33 of the printing unit 21, which are arranged those in a row (see Fig. 3), determine a row length that is equal to the desired width of the records on lane 17.

The pressing element 42 provides for a specific position 10 15 20 25 30 35 453 529 8 of the elements 33 relative to it past the roller 44 passing the web 17. The pressing means 42 can against the force of the said spring 43 is swung back to idle position for entering the track 17.

The bowl 53 has outside the position of the roller 18 a pocket 45 which serves to receive a insert 46.

The insert contains a programmable read only memory 47, in which the control program for receipt 19 is permanent pressure 28 is stored. Socket element 48, which is connected to the programmable read only memory 47, shoots out of the insert 46 and is, when the insert is inserted in pocket 45, connected to the coupling elements arranged there. 49, from which lines 50 emanate, which leads to said lead plate 41.

The circuit board 41 has a collection of electrical components. which is responsible for the control of the die printing plant 21 and Operation. These include a microcomputer 51, further a memory 52, which is called "programmable character memory" contains the size and shape of all available, numbered risky or alphanumeric symbols to be applied the receipt section 29 together with the fixed data. Give- through the replacement of the memory 52 it is possible to retrospectively also change the shape of the symbols for the variable data 29. Finally, the conductor plate 41 also carries a current switch 54 over which the plate is connected to the risk lines. This switch 54 is in turn in connection with said separating edge 26 and acting in the following way.

The separating edge 26 consists of the sharpened tooth the ends of a blade 55 which are used in a guide 56 arranged displaceable in parallel with itself and connected to a holding member designed as a link 57. This holding means 57 is provided with an arm bent at an angle 58 and has a fixed storage location 59. In the oscillating the path of the arm 58 is provided with an actuator for said switch 54. A spring 62 provides that the link S7 is pressed against a stop 60. The blade 55 is 10 15 20 25 30 35 453 329 9 displaceable in the direction of the drawn arrow 61, when the end of the web 17 is pressed against the separating edge 26 to cut off receipt 19 from the web, as already mentioned.

The function of the device is best seen in the diagram in Fig. 6, where the already mentioned components are indicated with the assigned numbers. In this motto, the current description, even if individual components compared to the ways in which they are concretely made in the previous figure, are schematically represented.

When tearing off the end part of the track 17 next to the separation 26 to obtain a receipt 19 for previous purchase, the switch 54 is moved via it movable blade 55 in operation, whereby the microcomputer 51 via the line 63 in Fig. 6 is caused to the printing plant 21 achieve the complete permanent the pressure 28 in the head 19 of the receipt 19 shown in Fig. 4.

To do this, the microcomputer 51 cooperates with the memory in the insert 46 over said lines 50 and affects the printing plant 21 via a control line 64. The pressure unit activates the item 33 for punctual record and operates it associated with the transport mechanism 66 in the pressure unit in time with these activations, whereby the path 17 which is seen to receive the record fed a definite paragraph. While the operator is still engaged in tear-off receipt and delivery of the receipt 19, this period shall be space to complete the permanent pressure for an upcoming purchase. After this, the device is immediately prepared for the additional work as shown in Fig. 4 the receipt appears from the variables recorded on this data 29.

The item 12 shown in Fig. 6 on the weight determination the unit 11 sends via the connection 14 another measurement signal the evaluation unit 10 connected to the unit 11, where the signal first enters an evaluation means 66, which transmits a corresponding signal via line 67 to a main computer 68, but also via external : w «w *“ M y, w's 10 15 20 25 30 35 453 329 10 lines 69 partly to the presentation unit 16 and partly to the microcomputer 51. In the presentation unit 16, the weight value of the article 12 appears digitally in it first indication field._Evaluation of this weight value for printing occurs suitably only after one impulse from the input device 15, so that for in the first place uses a not further shown, for microcomputer Sl available memory.

As also shown in Fig. 6 is sent from the input the device 15 either directly via the lines 71, 72 a unit price to the main computer 68 or indirectly through an interconnected, so-called "price-look-up" memory 70 via line 72 to the main computer 68. In both cases this signal is also sent via line 73 to the pre- station 16, where this value is displayed in the middle the reading window, and this impulse is passed on via line 74 likewise to the microcomputer 51 and to said associated memory. Whether the unit price occurs directly or indirectly depends on the the position of a switch 75, which is adjustable from the input device 15 by means of a no closer displayed control key. In switch 75 one, showed mode determines the influence of the keys on the input the device l5 directly the unit price. In the switch 75 second mode is the influence of the keys on the input only a code number as from there connected PLU memory 70 sends it there under this number containing the value on to the after current switch 75 connected the lines 72, 73, 74. In the main computer 68, the incoming input via line 72 is processed. price and that from the evaluation body 66 via the added 67 the weight value calculated and from here the associated commodity price is determined, which is a signal via lines 76, 77 is partly included in the presentation Unit 16, where this commodity price is shown in the last the reading window, and via line 77 likewise the microcomputer 51 is transferred to the existing one, respectively 10 15 20 25 30 35 453 329 11 the memory.

About those in the presentation unit 16 made visible variable data for item 12 is fixed and for item 12 to be included in the purchase, the microcomputer 51 is connected eg via a key not shown in more detail in the input device 15, so that the computer supplied respectively the values entered in the associated memory are recorded by the matrix printing unit 21, i.e. said weight value, unit .price and commodity price. This is done by the microcomputer S1 in accordance with the lines 69, 74, 77 the available signals they charge for the presentation of these symbols require data via a line 78 from said programmable character read memory 52 and do the matrix printing plant 21 correspondingly operates over the management 64. This is again done through coordinated activation of the printing elements 33 on the one hand and the gate mechanism 65 on the other hand. A series of variable data can be recorded in section 29 of the receipt 19 in Fig. 4.

It would also be conceivable to arrange a control such as stores multiple records variable data 29 or even all records and then writes several or all variables data in section 29 of receipt 19 in a single course.

To get another permanent print 28 on the receipt 19, it seems sufficient to simply exchange bet 46 for a corresponding other bet, provided then placed in the pocket 45 of the printing unit 20.

Fig. 7 schematically shows how easily a programming readable memory 47 for the insert 46 can be provided with the permanent pressure program.

On a model 79 is the shape of the desired print 80 recorded. This is now photographed using a video camera 81. After this optical conversion, a electrical video signal, which also contains video cameras all associated synchronization pulses, via line 82 to a demodulator 83. In this is separated image data from the synchronization signal and both are transmitted 10 15 20 25 30 35 453 329 12 via lines 84 to a control device 85, which is constituted of a microcomputer. In one in this arranged or before this coupled relational coupling, they are transformed as log signal present image data to a binary high-low signal. An adjustable reference value determines this binary conversion, whether a high or low signal occurs at a specific location in this signal sequence.

This reference value is set to a specific blackening of the model 79. Via a line 86 this binary is carried signal sequence to another video modulator 87 taking into account further synchronization ring pulses via line 88 send a video signal to a video terminal 90, where now one with the binary signal sequence achieved, rasterized image 9l of the desired pressure 80 arises. The row number resulting grid points 92 are less than / equal with the number of printing elements 39 in dot matrix printing the work, which is shown in the fragment in the already mentioned Fig. 3. From this rasterized image 91 it appears the printing works now determines the conversion of the model 80 to break points. Changes can still be made.

An image scanner 93 is used for such correction which is connected to the control device 85 via a 89. The scanner 93 carries an actuator 94, at the influence of which is intended to be a fixed raster point 92 ' converted to the opposite signal. In the assumed case changes a "black dot" 92 'prominent error, which can be from the print 80 of the model 79, to the complementary erode the signal, ie a "white dot". This is registered of the control device 85 and the corresponding corrected channels are then supplied to the video terminal 90 via wiring at 86, 88.

Furthermore, a keyboard can be attached to the control device 85 95 be connected via cable 96. With the keyboard keys, text data can be entered for completion of model 79 or instead of a model 79, which ka for control appears on the video terminal 90 as 10 15 20 25 30 453 329 13 numbers or letters. By means of special control pliers 97, it is possible to select the location of the these alphanumeric symbols on video terminals lens 90 monitor. Furthermore, a control pressure cork is 99 for example a thermal printing plant, connected to control devices 85 via a line 98. In this way one can check the final shape of the device stored pressure has received. The picture is legible on it paper strip 101. released by the printing press 99. Trigger of the control printing unit 99 takes place by means of a key 102 which is integrated with the keyboard 95.

Finally, there is also a programming device 100 connected to said control device 85 via a wire 103. The control device 85 now interrogates the final one the shape of the desired pressure, which is already divided in raster points, and programs it to the device 100 connected programmable read-only memory 47. This has has now received a control program, which is able to The matrix printing device 21 accomplishes the same permanent pressures that could be controlled in the above control printing press 99. The triggering of this can also be performed from the keyboard 95, because one corresponding to the programming instruction key l04 is arranged in this. The pre-programmed read memory 47 can now be removed from the device 100 and inserted into the housing of an insert 20, thereafter contacted in an appropriate manner for use in the arrangement according to the invention in the manner shown in Fig. 2. With the device shown in Fig. 7, when the rasterizing image 91 of the model is fixed and is stored there, any number of programmable read-only memories 47 with the same control program are produced.
