Description

Data Processing System The invention relates to data processing systems as well as devices and in particular, but not exclusively, systems and information retrieval devices.

In accordance with the present invention, a system for retrieving Information with a main data memory for storing data words at certain Storage spaces proposed, with an auxiliary data storage device for storing the Data words in an order that corresponds to the order of the data words in a Main memory is related, and tokalisierungseinrichtung available are, The help data memory is able to do so on the basis of one of the operator's minds sample given signal to determine the designation of a specific data word and to find the particular data word and further access devices which on the position of the particular data word found relative to other data words address to record the storage space in the main memory at which the specific Data word has been stored.

Also in accordance with the present invention is a retrieval system suggested by information, which has a data memory for storing Has data words in certain storage locations, and also Mitrofilme whose The data words are displayed in a sequential order accordingly record the order of the data words in the data memory, a localization device, which responds to a signal that represents the name of the specific data word, which should be found again to match the specific MiRofilmbild with the specific Find and display data word, switching devices to a first signal Establishing the position of the film image to produce a control device for the operator to determine the position of the particular data word in relation to other data words on the microfilm image and to generate a corresponding one second Identi £ izierungssignals and access devices, which on the first and second identification signals responding to the determined data words from the Retrieving data storage. In accordance with the present invention, there is also a method of operation suggested for the retrieval of certain data words from a data memory, in which a storage means records the data words one after the other in an order, which corresponds to the order in the data memory and which is scanned to a group on it of one or more data words to find which have the desired data word, with a first identification signal to determine the sequence of positions of the group found in which the indicated Group ebsamptes, and a second identification signal is generated, which determines the position of the desired data word within the group, whereby the two identification signals for access to the desired data word from the data memory be used.

In the following, the information retrieval system will be discussed according to the present invention by way of example only, with reference on the drawing. They show: FIG. 1 a block diagram of the Systems; Figure 2 in a schematic representation of part of a Nikrofilmstrip and one of the appropriately adapted code detectors; Figures 3, 4 and 5 in schematic form Representation of various codes that are attached to the microfilm strip can; Figure 6 shows a logic circuit of part of the system which is used for this purpose is to locate any desired microfilm image and Figure 7 is a logical one Circuit of a part of the system that is used to code the various To print out milrofilm images.

The data retrieval system described below is, stores data in a memory of a computer and the central unit of the By controlling a key-operated Nikrofil display, according to Art an address book, access to the correct memory locations. In the relevant System being described is a list of data words alphabetically on the Images of a t »Ek film strip, with an image usually several Data words listed. All data words on a Nikrofilmbild are the same First letter (which in the following is referred to as the first index! 1). All Data words in an image can also have the same second letter (hereinafter referred to as the 8 'second index "), but if not sufficient Data words with the same second index exist to make a microfilm image to fill in, other data words with different second indices can also be used are recorded on the image, the data words on such an image in Regarding their second indices, to be arranged alphabetically. If there are more data words which have the same first and second indices as in an image Can-be recorded, so the list can be on the next picture or the next Images to be continued if necessary. Every data word on the Nikrofilmstrip corresponds to a specific memory location, or group, of memory locations in the Memory of the computer.

For the operation used an operator who is assigned to a specific Data word in the memory of the computer access winches, an alphanumeric keyboard to enter the name of the data word. Finds in a manner yet to be described the system displays the specific picture on which the name of this data word appears (normally together with the names of many other data words). The found image is displayed along a keyboard operated by several push buttons or the like, one for each data word on the image is, and the push buttons to the specific data words to which they correspond, are arranged in a juxtaposition. The operator then operates the corresponding push button which corresponds to the specific data word on the picture which is to be retrieved. The identity of this push button and the one found Images are transmitted to the central unit, which according to the transmitted identities to the desired memory location or E; given access. On this In this way, an inexperienced operator can get to a specific storage site very quickly or a group of storage locations in the computer's memory, without assigning the address of such a memory location or such memory locations know. The microfilm is from an issue in a manner to be described of the computer memory $ processed.

As can be seen from Figure 1, the system has the central unit lo on, with which a computer memory 12 of a suitable type via an access line 14 is connected.

Also provided is a microfilm controller 16 which is a film drive mechanism 18 for driving and stopping the microfilm 19, a detector unit 20 for reading the code on each frame of the film and a display unit 22 for displaying a particular one Has film image. The display unit 22 has the push button actuator mentioned above Keyboard 23 to select a specific data word on the displayed image, where this keyboard is connected to the central unit 10 via a channel 24.

The keyboard £ eld 26 for the operator to enter the identity of a data word which is to be found is with the localization circuit 28 connected, which receives signals from the detector unit 20 via a line 3o, when the film is moving through the device 16, and which is the drive mechanism 18 via a line 32 controls. The localization circuit 28 is also with the Zentraleinlieit le via a channel 34 connected.

The central unit lo becomes this in a manner to be described below used to prepare the microfilm so that the data on the microfilm in correspondence are arranged with the corresponding storage locations in the computer memory 12. For this reason, the system has a typewriter 36 to write the data words, to be recorded on each image, and a print control circuit 38, which is connected to the typewriter via lines 40 and 42, which is controlled by the central unit lo via a line 44.

In Figure 2 is a strip of microfilm 46 with two adjacent one another 48 and 50 shown.

Each picture has a Datex area 48A and 50A for receiving the lists of the data words, a code area 483 and 503 for receiving a code and a part 48C and 50C for generating a clock step pulse.

FIG. 2 also shows detectors 51 to 56 of the detector unit 20 (see Figure 1). Each detector is a photoelectric converter and is about a corresponding light guide 54 with an associated detector head 51A to 56A tied together. The detector heads 51A to 55A are with the aid not closer The means shown are fastened in such a way that they correspond to the surfaces 48B, 503 of the film images are aligned when they pass through the detector unit 20. The code on the Code areas of each picture ict five, with each place either translucent or not translucent. A light source (not shown in the following) sends Light, towards the film from the opposite side of the same, to the detectors to and each detector 51 to 55 generates an electrical signal when the code position, which is read by the assigned detector head, is opaque. Of the Detector head 56A is aligned with timing pulse portions 48C, 500 of the film frames arranged when they pass through the detector unit, each such Geil causes detector 56 to generate a clock step pulse.

Figures 3, 4 and 5 show examples of codes based on the Code areas 48B, 50B of the film images can be produced1 Each code area has five code positions 58, 60, 62, 64 and 66. Identify code positions 58 through 64 a certain letter. The code position 58 therefore has, as shown in FIG is, an opaque marking, while the code positions 60 to 64 translucent are. The letter code is therefore 1 ooo and is therefore equal to the letter A. The film image in Figure 4 has the code oho, which corresponds to the letter F while the code in Figure 51 is 1001 and corresponds to the letter I.

The code position G6 of each image indicates whether the associated Code is a first or a second index. The presence of an opaque Marking indicates as shown in Figure 3; it is established that the letter, the is coded in the code area, is a first index letter. The absence of one opaque mark in the code position 66 indicates how from the figures 4 and 5 it can be seen that the letter is a second index letter.

The following explains the manner in which the images are encoded will.

As stated above, the data words are alphabetically on the Film recorded. The first picture, which data words with a certain first Index letter is encoded by a code that corresponds to this letter identified and is also provided with a mark in code position 66, to indicate that the encoded letter is a first index. The number of data words having the same first index is usually too big to be on a single picture To be forgiven, so that some more pictures below are used. Each these pictures are encoded in order to assign the second index of the data word to the picture identify, the sod position 66 being left blank to indicate that the encoded Letter is a second index. Need the data words on a particular picture not all to have the same second index (the number of data words with a certain second index may be too low otin to give a complete picture fill) and in this case the coded letter can be the lowest (alphabetically earlier) be the second index of all data words on the express.

In the hie @ besehricbenen @@@ ten the microfiln strip is recorded Deten @@ ter cinigen different types, whereby such different Species are recorded in successive groups of images. A picture that therefore a specific first index is identified, followed by a first group of images, which lists product names, which are sorted alphabetically according to their second indices are.

This first group of pictures is followed by a second group of pictures, which records the customers, with all customers in this second group being the same first index, like the customers in the first group which immediately precedes, and which are arranged alphabetically with respect to their second indices. The second group of images is then followed by a third group, which for example listed the suppliers, with all suppliers listed in the third group the same first index; like the products and customers of the first and second group, which of these immediately precede them, which in relation to their second Indexes are arranged alphabetically.

With reference to Figure 6 is described below in which way the system finds a specific film frame.

Using an example, it is assumed that the data word to be fixed the name "Jones" of a customer is. The desired image is therefore on the microfilm found after a picture has a letter code on its code area, which corresponds to the area 48B or 50B of Figure 2, the letters "J" and has a first index mark.

It is also assumed that the myriad of customers with the same second index ("O") like the ne Jones is not enough to complete a picture fill, and that the picture on which the name Jones appears, too other customers who have the same first index (J) but a different second Own index. The second letter encoded on the picture is on the the name Jones appears is therefore not 11011 but for example E, the second Index of the first name in the picture.

In the following, reference is made to FIG. The operator sets the name Jones on the keyboard 26 and also presses a-not Customer push button shown in more detail, which indicates that the set name is the name of the customer (as opposed to the name of a product or a supplier). Entering the name Jones using the keyboard causes a Uppercase 4-bit code representing the letter "J", the input of a AND gate 70 for a first index is fed, and a 4-bit code, which represents the letter 11011, the input of an AND gate 72 for a second Index. is fed. The remaining letters of the Jones name have been added to the system no effect. The actuation of the customer push button causes a binary code, which represents the decimal number "2" occurs on line 74.

The drive unit 18 (see Figure 1) of the microfilm device is now put into operation and the microfilm travels through the device. If a picture moves through the detector unit 20, causes its clock step pulse part II-8G, 50C (see Figure 2) that the detector 56 is connected to the input of an UlTD element 76 (see Figure 6) feeds a "1". A second input of this element is connected in such a way that that it is from detector 55 (see Figure 2). receive a signal can, while the detectors 51 to 54 send their signals to an input of a first comparator 77 whose second input has the first index code or the second index code can receive from the keyboard, depending on which of the two members 70 or 72 is controllable.

Furthermore, the detectors 51 to 54 are connected via a shift register 78 a second comparator 79 is connected.

The operation of the location circuit 28 is through a Flip-flop circuit Bo controlled. This flip-flop circuit is initially in their first state and generates a "1" signal on an output line 81, whereby the AND gates 70 and 76 and also an equality detector 82, the receives output signals from the comparator 77 via lines 83 and 84, control be able to work. The flip-flop circuit 80 is through an output line 86 also connected to the AND gate 72, but this line carries an "O" and the AND gate 72 remains closed. The line 86 also controls an AND gate 8 ?, whose output line 88 controls the shift register 78. When the line 86 a "O" leads, the AND gate 87 is not controllable, and the shift register 78 is not operational, so that from the detectors 51 to 54 to the comparator 79 none Get data.

When an image passes through the detector unit 20, it is detected by the detector @ 6 a clock step pulse is generated and fed to the AND gate 76. Each first index mark activates the Deiektor 55, which also feeds the AND gate 76 a "1". the The acquisition of each first index description means that the AND element 76 is a Output signal generates, which via an OR gate 92 altividit the Eonpaiator 77, the then the most In @@ x.

code supplied by the AND gate 70 with the code compares which is determined by the detectors 51 to 54 at this moment will; these detectors read the code parts 58 to 64 of the image accordingly (see Figure 3). If the first index code, which is supplied by the AND gate 70, lower (i.e. it is a letter that occurs earlier in the alphabet) or is equal to the code read from the image by detectors 51-54 are then applied to line 83 with a "1". If the code of the AND gate 70 is greater or lighter the code from the detectors 51 to 54, so the line 84 is acted upon. If both lines 83 and 84 have a "1'l, so this shows the identity between the first index code identified by the AND gate 70 is supplied and the code that is transmitted from the film by the detectors 51 to 54 are read, whereby the AND gate 82 on a line 94 an output signal generates the flip-flop circuit 80 to switch to its other stable state and a counter 96 opens. This counter is connected in such a way that it Counting signal, which is on line 74, receives and when it is on opened in this way, a counter 98 is changed by a corresponding amount. (the decimals 2) When the flip-flop circuit 80 has toggled, the line is conducting 81 an "O", which closes the AND gates 70 and 76, and the AND gate 82 ineffective power. The line 86 is now a "1", whereby the AND gate 72 and 87 can be controlled will.

The film movement is continued. When an image is passed through the detector unit 2o runs, a clock step pulse is generated by the detector 56, and the AND gate 76 causes a "1" to be generated on line 88.

which activates the comparator 77 via the OR gate 92, which thus compares the code provided by the detectors 51 to 54 with the code, which is supplied via the UTD element 72. As before, the comparator 77 generates on line 82 a "1" if the code which is supplied by a WfD gate 72 is less than or equal to the code supplied by the detectors 51 to 54 will. Since the line 81 carries UOtt, the “equality detector 82 is inactive, however the signal on line 83 is sent via line 1o2 to a second equality detector 104, which is activated by the signal on line 88.

Any code supplied to the comparator 77 by the detectors 51-54 is also fed into a shift register 78. When the next picture is read, the clock pulse, which is generated thereby, causes with With the help of the 1 "generated on the line 88, that the code in the shift register 78 the second comparator 79 is fed, where it is with the second index code, which is fed via the AND gate 72, is compared. The comparator has an output line 106 which carries a "1" if the code, which is via the AND gate 72 is supplied, is greater than or equal to the code which is from the shift register 78 is applied and this signal is applied to the equality detector 104. While this comparison is being made, the comparator 77 compares the image code, which last by the detectors 51 to 54 with the second index code via the AND gate 72 was fed.

The comparators 77 and 79 therefore compare the picture codes of two consecutive images with the second index code which is via the AND element 72 is coming.

If both lines 83 and 106 carry the "1", this indicates that the desired second index on the picture must be found which immediately follows the image which is being viewed by the detectors and equality detector 104 generates a "1" on line 108 as Output signal. However, this image will not be the one you want because it is a Image is in the first group of images that follow the image that is the first index "J" leads and it therefore lists products and not customers as requested. The signal on line 108 therefore does not stop the film, but rather causes the counter 98 to go back one count and continue film movement will. During this continued movement, the comparators 77 and 77 compare 79 furthermore the picture codes of the neighboring pictures with the second index code, which is fed in via the AND gate 72. When the equality detector 1o4 again a 11111 is generated, this indicates that the desired image is in the second Group of images has been found, i.e. in the group in which the names of the Customers are listed. The resulting signal on line 108 counts Counter 98 returns to zero and this returns via contribution 32 (see also Fig 1) from a signal by which the drive unit 18 is brought to a standstill, causing the movie to stop. It is beneficial if the image you want already has the Detector unit 20 has passed (since the AND gate 1o4 has no "1" output signal can generate until the image that follows the desired image through the detectors 51 to 54 has been read) However, the detectors are sufficiently far in front of the Display unit 22 arranged so that the correct image is displayed when the Film is brought to a standstill.

If the film only lists customers, (there is only one group of images, which follows the first index picture) so can from the lines 74, the AND gate 96 and the counter 98 can be omitted, and the signal 1 "on the line 108 can be used to film the Bring to a standstill.

The above description is based on the assumption that the desired Data word one of different data words with different second indices is on the same picture and that the desired picture is coded with a second index, which is different from the second index of the desired data word. It may however, it should be noted that the creation works properly even in the case where which the desired picture actually has a coding which has the second index of the data word which is to be found.

When the desired image is found in the whiteness explained above its identity is communicated to the central unit lo with the aid of the line 34 transmitted. The line 34 can, for example, carry a count (which for example derived from the clock step pulses generated by detector 56), which determines the sequential number of the film frame. When the operator checked the displayed image and found the particular desired data word has, she actuates the corresponding pushbuttons 23 (see Figure 1) which the desired Data word are assigned, and a corresponding signal is sent to the central unit transmitted on channel 24. The through the central unit on lines 24 and 34 received signals completely identify the desired data word and set the address of the memory locations in the memory 12 by storing this data word is, and the central unit 10 is thus given access to the correct memory.

In this way the operator is able to use any data word to retrieve from the computer memory without knowledge of the address of the memory in which it is stored.

So that the system works properly; it is necessary that the data words placed on the film in a manner corresponding to that in which they are stored in the computer memory. This can be achieved by ate the film itself by printing out the contents of the computer memory with one Manner, which is described with reference to Figure 7 in the following will.

The computer printout has the contents of the computer memory, which can be printed out as standard. With the help of this calculating pressure, the calculating machine 36 (manually or automatically) used to put the data words on an appropriate Print out material that will later be photographed to make the microfilm, each side of the material representing a film frame. s One on each side If there is a fixed number of data words, the position of each data word is correct on a page and the consecutive number of the page with the location of the Data word in the memory 12 match.

Since each word of data is printed out by the typewriter 36, the first and second indices of the same coding device 120 and 122 are added. The encoder 120 generates a four-bit code on lines 124, the one Comparator 126 and a shift register 128 is fed, the output lines are also connected to the comparator 126. Since every new data word written is, its first index code is fed to the comparator 126, where it is matched with the first Index code of the previous data word is compared, this last code is shifted through the shift register 128 by the new code. When the comparator finds that the two modes he is comparing are different, so becomes one Line 130 energized, which a flip-flop circuit 132 in a first stable state switches, whereby an output line 134 is energized.

This indicates that the first index of the data word, which is different from that of the previous data word. The data words are arranged in the computer memory in such a way that a change of the first index only takes place at the beginning of a new page. When the comparator 126 determines that the first two index letter encodings compared are the same, so will. a line 136 energizes which the flip-flop circuit 132 switches to its second steady state, thereby energizing an output line 138 will.

The lines 134 and 138 make the AND gates 140 and 142 'controllable, which the coded output signals from the encoders 120 and corresponding 122 received. The AND gate 140 has four output lines around the four bits of the first index code, which is generated by the coding device 120, in a corresponding manner Way and these lines are connected to the data AND gates 142, 144, 146 and 148 are connected accordingly, and the output lines of these: elements are connected to a common line 15o via an AND gate 152 with the typewriter 36 Help line 40 linked.

The output of a further AND element 154 is connected to line 150 connected, one input of this AND-gliod being linked to the line 134, so that it arouses if there is a change in the first index is detected.

The respective second inputs of the AND gates 142, 144, 146 and 148 are connected to the outputs 156A, 156B, 156D, and 156E of a sequencer 156. The output 156C of this sequential control is connected to the second input of the AND gate 154 linked. The sequencer 156 is activated by pulses from the Divider circuit 158 are received, which in turn are excited by pressure pulses which occur on line 16o. Just one of the outputs of the pole control 156 is energized at a time when the outputs n of the sequence 156A, 156B, 156C; 156D, 156E, 156A, 156B, ..., where -each pulse, de; from the rim steering 156 is received causes the next successive output to be energized. For this The AND gates 142, 144, 146, 148, and 154 are basically in the order 142 144, 154, 146, 148 made controllable.

When a full page of data words has been written, will be on the line 160, with the help of means not shown, rows of Quick pressure pulses generated and the divider circuit 158 and the AND gate 152 fed in. Assuming that line 134 is energized (causing a change of the first index since the previous page is displayed) so the four-bits (each of which is either "1" or "G") of the new first index to the AND gates 142 to 148 forwarded accordingly. The sequencer 156, which is initially in is in the state in which line 156A is energized, causes the bit which is fed to the data element 142, on the line 150 to the AND element 152 is forwarded. This data bit corresponds to the code position 58 (see Figure 3, 4 and 5). If the data bit is a "0", the AND element remains 152 closed and the pressure pulses, which are supplied on line 160, have no effect. However, when the data bit is a "1", the AND gate becomes 152 made controllable and each of the rapid pressure pulses on line 160 causes a light obscuration mark to be printed on the page.

The scale of the divider circuit 158 corresponds to the number of pressure pulses, which are required to print enough marks so that the width the I-coding position 58 can be filled out. When this number of pressure pulses therefore has been received, the divider circuit 158 causes sequencing 156 advances to the next position in its sequence and the data bit from the data AND gate 144 is now fed to the AND gate 152 and the method described above repeated.

When the sequencer 156 switches to its next following position, the AND gate 154 becomes controllable and the excitation of the line 134 is effected, that through this AND gate a 11111 is fed to the AND gate 152, so that a The first index mark is printed out in code position 66.

Then the sequential control 156 makes the tflD elements 146 and 148 controllable, so that a corresponding coding of the code positions 62 and 64 is effected.

If the comparator 126 determines that the first index of the first Data word on the new page is the same as the first index on the previous page is, the line 138 is energized instead of the line 134 and AND gate 142 'word opened so that the codes which the second indices of the printed data words are fed into the circuit. That AND gate 140 is kept closed. With the help of the lines 162 these Codings fed one behind the other to a shift register 164 and likewise to one Set of inputs of a comparator 166, the other set of inputs of which is from fed to the output of shift register 164; The comparator 166 has an output line 168 which is only energized when the comparator determines that the code which is fed to it via lines 162 has a preceding one Letters in the alphabet corresponds as the code that is on the shift register 164 was delivered. The excitation of the circuit 168 makes an AND gate 170 controllable, which is connected to receive clock pulse pulses on line 171 can, namely one clock pulse for each data word. Every one of those Pulse therefore causes the data on line 162 to be lost at this point shifted into shift register 164 and that previously in shift register are fed to the data AND gates 142 to 148.

The effect of shift register 164 and comparator 166 is hence, make sure that when all the data words for the page are written shift register 164 has the lowest size of the second index letter (the earliest letter in the alphabet) of all data words on the page. This letter code is fed to the data AND gates 142 to 148 and the One after the other in the code positions 58 or 64 through the pressure pulses, which are on the Line 16c received, in the same manner as explained above, printed out. If line 134 is not energized, AND gate 154 becomes inoperable and the code 66 remains blank to show a second index.

The system described can be modified in various ways. In particular, if the number of data words warrants it, images that are coded according to the third index of the data words, can also be provided, wherein these images are of course arranged between the images encoded with the second indices will. For example, a first index code in such a system could be an image can be displayed which is blank except for the letter code which is the specific one first index and a second index code could be marked in the Code position 66 (see Figure 3) should be displayed (i.e. the position for the first Indoxr: marking in the 5 system already described) and the third index marking could be indicated by a space in the Itode position 66. The circuit would be modified accordingly.

It is particularly advantageous that the system itself is modifications of the coped with stored data. For example, the computer memory 12 can also empty Memory places be provided, which interspersed between the stored data words so that the insertion of additional data words and a slight rearrangement of the existing data words in the memory is possible. Such a modification of the stored Data does not require any modification of the devices for access to the stored data. It is only necessary that a new ikrofilm in the manner explained above is prepared directly from the computer printout. From this new I5krofilm one can inexperienced operators can easily find any desired data word in the rearranged Find memory.

It is particularly advantageous that there is only one data word on each picture needs to be present, in which case the row of press studs 23 (see Figure 1) is not required.

Instead of using translucent and darkening Markings for coding the film images in connection with light-sensitive Reading devices can also use other coding arrangements, such as magnetic markings and appropriate detectors are used.

It is also advantageous that the system for displaying the recorded Data words must use your microfilm, but that some other suitable one Display medium can be used. The nedium does not have to be such a at which the data words are physically represented by markings} but cs e.g. also an electronic display (e.g. a cathode ray tube) with appropriately assigned auxiliary storage devices are used. in which few or no data words with one or more first indices are present, it can be advantageous if an image of the microfilm data words leads with various first indices. In such a hall, the picture can with a letter coding corresponding to the earliest first index on the picture be, and the device can be modified so that the picture is in the same way it is found how the device according to Figure 6 determines an image, the data words with more than one second index leads.
