Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a pattern matching device that matches a pattern to be matched with a standard pattern registered in advance.

(Prior Art) A method for comparing a pattern to be matched such as a seal stamp formed on a medium with a standard pattern is to use an image reading device to compare the pattern to be matched on the medium and the registered standard pattern on the same screen on a display. There are two methods: a method in which a registered standard pattern is displayed on a display and compared with a pattern to be matched on a medium, and the like.

FIG. 5 shows a configuration diagram of an example of a conventional pattern matching device. In the figure, 1 is a master book with standard patterns, 2 is an image reading device that reads the standard patterns, 3 is a control unit that controls each input/output device of this device, 4 is a master book file in which standard patterns are registered, 5 6 (6-1 to 6-n) is a registration keyboard for adding and registering search data such as an account number to be searched from the collation keyboard 6 when registering a standard pattern in the register file 4; Collation keyboard for inputting search data when reading standard patterns from 7 (7-1~
7-n) is a verification display that displays a standard pattern. In addition, this verification display 7
It is also possible to display the standard pattern and the pattern to be matched at the same time for matching.

To explain the operation, first, the standard pattern on the original register 1 is read by the image reading device 2, and the read data is sent by the control section 3 to the original register file 4 as a standard pattern and registered. At this time,
The control unit 3 also registers the search data such as the account number input using the registration keyboard 5 in the register file 4. When the operator wants to call up the standard pattern in the original file 4, the verification keyboard 6
-1 to 6-n, any 6-i (1i
Enter the search data in step n). Then the control section 3
recognizes the device number 6-i of the collation keyboard on which the input was made, and calls the standard pattern corresponding to the input search data from the original file 4. And a collation display 7 corresponding to the collation keyboard 6-i into which the search data has been input.
-i outputs a standard pattern and performs verification.

(Problems to be solved by the invention) However, in the conventional pattern matching device configured as described above, one matching display is always required for one matching keyboard.
Verification displays for the number of operators were required. Furthermore, since it takes only a very short time for the operator to display a pattern on the verification display and perform verification, the reality is that the verification display often does not display anything.

Although having one verification display for each operator is a waste of space, conventional devices have the disadvantage that the verification display cannot be used efficiently.

This invention was made in order to eliminate the above-mentioned drawbacks, and the purpose is to provide a pattern matching device that can expand the space, effectively use the matching display, and reduce the cost of the device.

(Means for Solving the Problems) In order to solve the above-mentioned problems, this invention aims to (a) match standard patterns on a master register in a pattern matching device that matches a pattern to be matched with a standard pattern registered in advance; (b) standard pattern storage means for storing the standard pattern read by the pattern reading means; and (c) search information for specifying a standard pattern to be read and matched from the standard pattern storage means. a plurality of input means (keyboard for verification) for inputting data; (d) a display means (display for verification) that is shared by the plurality of input means and displays at least the standard pattern among the pattern to be verified and the standard pattern; ) rotating means for rotating the display means; (f) reading out a corresponding standard pattern from the standard pattern storage means based on the search information from the input means and displaying it on the display means, and inputting the search information; (g) a control means for outputting a rotation instruction including identification information for identifying the input means that has been input; and rotation control means for controlling rotation.

(Function) According to this invention, since the pattern matching device is configured as described above, the following function is achieved.

The pattern reading means reads the standard pattern on the register based on instructions from the control means, for example. The read standard pattern is sent to and stored in the standard pattern storage means by the control means. During pattern matching, search information for a standard pattern to be matched is input from the input means, and upon receiving the search information, the control means reads out the standard pattern to be matched from the standard pattern storage means and displays it on the display means. . Here, since the display means is shared by a plurality of input means, the rotation means rotates the display means so that the verifier can see the data displayed on the display means. point it at the person who is checking it. This rotation is controlled by the rotation control means based on a rotation instruction from the control means that includes identification information of the input means that input the search information. In this way, the display means can be operated efficiently, and the problems of the prior art described above can be solved.

(Example) An embodiment of this invention will be described below.

FIG. 1 is a block diagram of a pattern matching device according to an embodiment of this invention. In the figure, reference numeral 11 denotes an original book with standard patterns, 12 an image reading device that reads the standard patterns, 13 a control unit that controls each input/output device of this device, 14 an original book file in which standard patterns are registered, and 15 16 (16-1) is a registration keyboard for adding and registering search data such as an account number to be searched from the collation keyboard 16 when registering a standard pattern in the register file 14;

This is a rotating device, for example, made of a motor, which changes the direction of the screen of 7.

To explain the operation, first, the standard pattern on the original register 11 is read by the image reading device 12,
The read data is sent as a standard pattern to the original file 14 by the control unit 13 and is registered.
At this time, the control unit 13 also registers the search data such as the account number input using the registration keyboard 15 in the original file file 14. When the operator wants to call up a standard pattern, the operator presses the verification keyboard 1.
Any 16-i (1

m) causes the matching device to output the called standard pattern; This verification device 18-j is shared by a plurality of verification keyboards.

In the verification device 18-j, the signal from the control section 13 is received by the verification device control section 19-j. When confirming that the received signal is standard pattern data, the verification device control section 19-j sends the signal to the verification display 17-j. When the sending of this signal, that is, the data of the standard pattern, is completed, the control unit 13 sends the device number 16 of the collation keyboard into which the search data of the standard pattern was input.

rotate it in the specified direction. The rotation direction and angle at this time are determined by the display rotation control section 20-j.
is set in advance according to the device number of the verification keyboard. Therefore, for the same verification keyboard, the corresponding verification display can always be oriented in a fixed direction.

Next, the rotating operation of the collation display will be explained with reference to FIG. 2. FIG. 2 is a mechanical diagram of this operation. Note that the optional verification display 17-j will be described here. In Figure 2,
19-j is a verification device control section, 20-j is a display rotation control section, 21-j is a rotation device, 22-j
is an address discrimination circuit, 22a-j are memories, 23
-j is a rotating device drive unit, and 24-j is a rotation measuring circuit.

The display rotation control section 20-j receives an address signal from the verification device control section 19-j, and the address discrimination circuit 22-j discriminates the address signal. The address discrimination circuit 22-j is provided with a memory 22a-j in which data (rotation direction and rotation angle) regarding the rotation of the verification display corresponding to the device number of the verification keyboard 16 is stored in advance. Therefore, the address discrimination circuit 22-j
reads the setting data corresponding to the input address signal from the memory 22a-j, and based on this setting data, gives a direction of rotation (left or right) to the rotating device drive unit 23-j. As a result, the rotating device driving section 23-j instructs the rotating device 21-j to rotate, and the rotating device 21-j is driven to rotate the verification display 17-j by a certain angle in the designated direction. The rotation value at this time is measured by the rotation measurement circuit 24-j. The sign of the measured value is (0) when the verification display 17-j faces forward, (+) when clockwise rotation, and (-) when counterclockwise rotation. This measured value is sent to the address discrimination circuit 22-j. Address discrimination circuit 22-
j, the rotating device drive unit 23-j is rotated until the measured value by the rotation measuring circuit 24-j becomes equal to the setting data.
Sends the rotation instruction to , and stops sending the rotation instruction when both are equal. As described above, the rotating device 2
1-j allows the verification display to be rotated to a predetermined position.

FIGS. 3a and 3b are diagrams showing an example of the arrangement of the apparatus of this embodiment. In these figures 26 (26-1, 2
6-2,...) is a collation keyboard for searching the original file 14 in Figure 1, 27-1 is a collation display that displays standard patterns (or standard patterns and patterns to be matched), and 28-1 is a collation keyboard. The verification device 29 (29-1, 29-2,...) includes the display 27-1, the display rotation control section 19-1 shown in FIG. 1, the display rotation control section 20-1, and the rotation device 21-1. A verification person (operator) 30 is a counter on which a verification keyboard 26 and a verification device 28-1 are placed.

FIG. 3a shows a case where there is one matching device for two matching keyboards, and FIG. 3b shows a case where there is one matching device for three matching keyboards. The latter example is particularly frequently used by the central collator 29-2, and by the other two collators 29-1 and 29-3.
Suitable for occasional use.

FIG. 4 is an external view showing an example of a verification display used in this embodiment. The method shown here is a method in which a standard pattern and a pattern to be matched are simultaneously displayed on a screen to perform matching. The display part of the collation display is of a type that swings its head using a rotating device such as a motor, and by measuring the number of revolutions of this rotating device, the swinging angle can be controlled as described above.

In FIG. 4, numeral 37 is a verification display that simultaneously displays the standard pattern and the pattern to be verified for verification, 38 is a verification device including a verification display, a rotation device, a display rotation control section, and a verification device control section, and 39 is a verification device. 40 is a turntable provided below the collation display 37, and 41 is a belt connecting the turntable 40 and the rotation device 39. This belt 41 is firmly connected to the turntable 40 and rotating device 39 without slipping. As a result, the rotating device 3 in the verification device 38
9 is rotated by the turntable 4 via the belt 41.
0 to the verification display 37 above. Rotation angle θl of verification display 37 and rotation device 39
The relationship between the rotation angle θr and the rotation angle θr depends on the radius of the belt connection portion of the rotating device 39 and the radius l of the turntable, and is expressed by the following equation.

θl=r/lθr Based on this formula, the swing angle of the collation display 37 can be set.

(Effects of the invention) As explained above, according to this invention, the display means (display for verification) is shared by multiple input means (keyboard for verification),
Since the display means is configured to automatically rotate in the direction of the input means into which search information is input, the display means can be operated efficiently, which is possible due to the lower cost of the device, and the display means can be rotated. This saves the trouble of having to set the input means, and the comparison can be easily performed using the same operation as when the display means is provided as an input means separately. Furthermore, since the installation space for the device can be reduced compared to conventional devices, the device can be used even in places with little free space. Furthermore, when not in use, the display means can be oriented in any direction, and when in use, the person performing the verification work can, for example,
Since the direction can be changed from side to side, etc., the device can also be used for both the first line and second line of financial institutions, etc.
