Description

  The present invention relates to a paper sheet identification device used for identifying various types of paper sheets such as banknotes, gift certificates, coupon tickets, authenticity, acceptance / non-acceptance, etc., and in particular, preset paper sheets. The present invention relates to an identification specification changing method for changing the identification specification of a class.

  In paper money identification devices, for example, bill recognition devices mounted on vending machines, automatic change machines, gaming machines, etc., read optical information, magnetic information, etc. carried on the inserted bills, The read information is compared with identification information set in advance to identify the type, authenticity, acceptability, etc.

  It may be necessary to change the identification specification set in the banknote recognition apparatus after the device in which the banknote identification apparatus is incorporated starts operation at the installation location. For example, when a certain period of time has passed since the ticket gate of the banknote, when accepting old banknotes is prohibited, there are cases where the criteria for authenticity determination of specific banknotes are tightened for the countermeasure against counterfeit banknotes.

  In order to be able to change the identification specification set in the banknote recognition apparatus at the installation location, the banknote identification apparatus is provided with a switch for changing specifications. For example, the identification specification can be changed by using a dip switch arranged on the back of the apparatus. When switches are used, the number of switches increases corresponding to the number of change setting items in the identification specification, so the number of change setting items must be limited when the number of switches is limited. There are restrictions.

Patent Document 1 proposes a paper sheet identification device capable of changing the identification specification without using a switch. In the paper sheet identification apparatus disclosed herein, an identification specification change paper sheet different from the paper sheet to be identified is created, and the identification specification is changed using this.
JP 2004-86839 A

  However, in the method of using a dedicated paper sheet for changing the identification specification, it is necessary to create and store the number of identification specification change paper sheets corresponding to the identification information change setting item.

  In addition to the original identification process, it is necessary to add a process for identifying such a dedicated identification specification changing sheet and reading the information carried therein. As a result, the capacity of the control program stored in the storage unit of the banknote recognition device and the number of development steps thereof are increased, leading to high costs.

  In view of the above, an object of the present invention is to provide an identification specification changing method for a paper sheet identification apparatus that can make changes to various identification specifications without using a switch or a dedicated identification specification changing paper sheet. Is to propose.

In order to solve the above-described problems, the present invention provides an identification for changing the identification specification in a paper sheet identification device that identifies a paper sheet such as a bill inserted according to a predetermined identification specification. In the specification change method,
Switch the paper sheet identification device to a change mode for changing the identification specification,
Insert the correct paper sheet included in the identification target,
Identify the type of inserted paper sheet, the orientation of the front and back, the insertion direction, and the number of inserted sheets, and read banknote information including a combination of these elements .
The identification specification is changed based on the identification specification information for change previously associated with the read bill information.

  In the present invention, the identification specification is changed using the paper sheet to be identified. Therefore, it is not necessary to use a dedicated identification specification changing paper sheet, and it is not necessary to add a reading process for that purpose. Further, since the identification specification is changed based on the combination of the type of paper sheet to be inserted, the front / back orientation, the insertion direction, and the number of inserted sheets, it is possible to deal with a large number of identification specification change items.

Here, the above-mentioned regular paper sheets are repeatedly inserted, the type of the inserted paper sheets, the front / back direction, and the insertion direction are identified , and the arrangement pattern of the combination order of these elements is included. You may make it change the said identification specification based on the identification specification information for a change which read banknote information and matched previously with the read banknote information. By using a plurality of paper sheets in this way, it becomes possible to deal with more various identification specification change items.

  Further, in the present invention, when the identification specification includes an identification specification for identifying authenticity of each acceptable paper sheet, at least one acceptance is possible as a change of the identification specification. This includes a change to switch the identification specification of a paper sheet that cannot be used, and after the change of the identification specification, acceptance of a paper sheet whose identification specification has been disabled is prohibited. Yes.

  For example, in the banknote identification device, when the acceptance of old banknotes is prohibited after a certain period of time has passed since the banknote ticket gate, such identification specifications may be changed.

  Furthermore, the identification specification includes an identification specification for identifying the authenticity of each acceptable paper sheet, and the identification level for the authenticity identification of at least one paper sheet has a different discrimination level. When multiple discrimination criteria are included, the change to the discrimination specification with a different discrimination level is included as a change in the identification specification for paper sheets to which a plurality of discrimination criteria with different discrimination levels are assigned. It is characterized by being.

  For example, in a banknote identification apparatus, when the authenticity determination criteria of a specific banknote are tightened for countermeasures against counterfeit banknotes, the identification specification may be changed.

  Next, in the present invention, the change mode can be set by operating a manual operation member such as a dip switch.

  In addition to this, or instead of this, the paper sheet identification device may be set to the change mode for a certain period of time after the power is supplied to the paper sheet identification device.

  Next, the present invention relates to a paper sheet discriminating apparatus, and is characterized in that a set identification specification is changed by the above method.

  In this invention, the setting of identification specification can be changed by inserting the banknote of identification object into the paper sheet identification apparatus switched to the change mode for changing identification specification. Therefore, compared with the case where dedicated identification specification changing paper sheets are used, the cost for creating such a dedicated paper sheet becomes unnecessary, and the storage thereof is also unnecessary. Moreover, since it is only necessary to read the banknote to be identified when the specification is changed, it is only necessary to incorporate a control program for changing the setting of the simple identification specification as compared with the case of reading the dedicated identification specification change paper sheet. Development man-hours and capacity can be minimized.

  Embodiments of a paper sheet identification apparatus to which the present invention is applied will be described below with reference to the drawings.

  FIG. 1 is an overall configuration diagram showing a banknote recognition apparatus to which the present invention is applied. The banknote identification device 1 of the present example includes a banknote insertion slot 3 formed on the front surface of the apparatus housing 2, a banknote transport path 4 for transporting a banknote P inserted therefrom, and the banknote transport path 4. It has the banknote conveyance mechanism 5 which conveys the banknote P. FIG. A bill presence / absence sensor 6 for detecting whether or not a bill P is inserted into the bill insertion slot 3 is disposed in the vicinity of the bill insertion slot 3 in the bill transport path 4. A banknote reading sensor 7 for reading information carried on the banknotes P transported along the banknote transport path 4 by the banknote transport mechanism 5 is disposed in the middle of the banknote transport path 4.

  As the banknote reading sensor 7, an optical sensor that detects an optical feature that forms a light / dark pattern or a transmitted light pattern of the banknote P, and a magnetism that detects a magnetic feature that forms a magnetic pattern by a component of ink printed on the banknote P. A sensor or the like can be used. Of course, it can also be set as the structure provided with both of these sensors.

  The detection signal of the bill presence sensor 6 and the reading information of the bill reading sensor 7 are supplied to the control unit 10. The control unit 10 is configured around a microcomputer. When the banknote presence sensor 6 detects that the banknote P has been inserted, the control unit 10 drives the banknote transport mechanism 5 so that the inserted banknote P is transferred to the banknote transport path 4. Then, the carrying information of the banknote P transported by the banknote reading sensor 7 is read, and the type, authenticity, and acceptability of the banknote P are identified based on the read information. In the banknote identification process, the identification information of the inserted banknote P is performed by collating the read information read by the banknote reading sensor 7 with an identification specification such as a preset criterion. When it is detected that an acceptable bill is inserted, the bill P is sent out from the rear end 4a of the bill transport path 4 to a bill storage section (not shown) on the rear stage side. When the banknote is identified as an unacceptable banknote, the banknote transport mechanism 5 transports the banknote P in the reverse direction and discharges the banknote P from the banknote insertion slot 3.

  FIG. 2 is a functional block diagram of the control unit 10. The control unit 10 holds the identification specification storage unit 11 in which an identification specification D11 such as a determination criterion for the banknote P is stored and the banknote reading information D7 read by the banknote reading sensor 7 in the identification specification storage unit 11. The banknote identification processing unit 12 that identifies the banknote P by collating with the identification specification D11, the drive control unit 13 that drives the banknote transport mechanism 5 based on the identification result in the banknote identification processing unit 12, and the identification specification D11. And an identification specification changing unit 14 for making changes. The identification result is also supplied to a control unit (upper device) of a device in which the bill recognition device 1 is incorporated or a device to which the bill recognition device 1 is connected.

  The identification specification changing unit 14 is connected to a mode switching unit 16 for switching the banknote identification processing unit 12 from the normal banknote identification mode to the identification specification changing mode. As the mode switching unit 16, a manual operation member such as a dip switch incorporated in the circuit board can be used. Instead of this, it may be configured to set the identification specification change mode for a predetermined time after the power is turned on to the banknote recognition apparatus 1 and switch to the normal banknote recognition mode after the predetermined time has elapsed. Of course, it is also possible to have both configurations.

  When switched to the identification specification change mode, the banknote recognition processing unit 12 identifies the type of the inserted banknote P, the front / back direction, and the insertion direction from the banknote reading information D7 read by the banknote reading sensor 7, Is generated and supplied to the bill information comparison processing unit 17 of the identification specification changing unit 14. The banknote information comparison processing unit 17 searches the specification change information storage unit 18 for the identification specification information for change assigned to the banknote information d12 and outputs the obtained identification specification information for change to the identification specification information writing processing unit 19. To do. The identification specification information writing processing unit 19 updates the contents of the identification specification storage unit 11 using the supplied identification specification information for change.

  In the specification change information storage unit 18, banknote information D1 to Dn (n is a positive integer) indicating the type of banknote, the front / back direction, and the insertion direction, and changes assigned to these banknote information D1 to Dn, respectively. The identification specification information D1 ′ to Dn ′ for use is stored and held in advance. In the banknote information comparison process part 17, the identification specification information for a change (D1'-Dn ') assigned to the banknote information (D1-Dn) which corresponds to the banknote information d12 is searched, and this is output. ing.

  FIG. 3 is a schematic flowchart mainly showing the setting change operation of the identification specification of the banknote identification apparatus 1. In the normal bill recognition mode, when the bill P is inserted, the bill reading information D7 by the bill reading sensor 7 is collated with the identification specification D11 in the identification specification storage unit 11, and the type and authenticity of the bill P are verified. Are identified (steps ST1, 2, 3).

  When the mode switching unit 16 switches to the identification specification change mode, the banknote recognition processing unit 12 identifies the type of banknote inserted, the front / back direction, and the insertion direction from the banknote reading information D7 by the banknote reading sensor 7, The banknote information d12 representing these is supplied to the banknote information comparison processing unit 17 (steps ST1, 4, 5).

  In the banknote information comparison process part 17, it is compared whether the banknote information which corresponds to the supplied banknote information d12 exists in the banknote information D1-Dn of the specification change information storage part 18 (step ST6). If there is no matching information, the inserted banknote is returned from the banknote insertion slot 3 and a notification is made that the identification specification cannot be changed. For example, the fact is displayed on the display unit of the device in which the bill validator 1 is incorporated.

  On the other hand, when there is matching banknote information, the identification specification information for change (D1 ′ to Dn ′) assigned to it is read (steps ST7 and ST8) and stored in the identification specification storage unit 11. It is written and its contents are updated (step ST9).

  For example, it is assumed that a thousand yen bill is inserted from one end with the surface facing up, and the specification change information storage unit 18 holds bill information corresponding thereto, for example, bill information D1. . Further, the identification specification information for change D1 ′ assigned to the bill information D1 is identification specification information corresponding to a content such as “raise the true / false judgment criterion of a thousand yen bill to a strict level”, for example. And In this case, the identification specification for authenticity determination of the thousand yen bill preset in the identification specification storage unit 11 is rewritten by the identification specification information for change D1 '. Or in the identification specification memory | storage part 11, the setting state from which the thing with a loose reference | standard was validated as the judgment reference | standard for true / false judgment of a 1000-yen banknote is switched to the state where the thing with a severe reference | standard becomes effective. The inserted bill P is returned from the bill insertion slot 3 after being read by the bill reading sensor 7.

  After the identification specification is changed in this way, the bill type and authenticity are identified based on the changed identification specification.

  As described above, in the banknote identification device 1 of this example, when switching to the identification specification change mode and inserting one of the banknotes P to be identified with the front and back direction and the insertion direction being inserted, it is set there. It is possible to change the identification specifications of the banknotes that are present. Accordingly, there is no need to use identification specification changing paper sheets, and it is not necessary to create and store such paper sheets. Moreover, various identification specification change items can be set by changing the type of banknote P to be inserted, the front / back orientation, and the insertion direction. Furthermore, since the identification specifications can be changed by reading the banknotes to be identified, it is possible to minimize the system change and the change / addition of the control program for reading the dedicated identification specification change paper sheets.

  In this example, when the identification specification is changed, the identification specification for change is set according to the type of bill to be inserted, the front / back orientation, and the insertion direction. One of these may be used. In addition to these, repeatedly insert the same type of banknotes, identify the front and back direction and insertion direction for each insertion, and based on these insertion order patterns after inserting a predetermined number, change identification specifications It may be set. Furthermore, different types of banknotes may be repeatedly inserted, and the change identification specifications may be set based on patterns of types of banknotes to be inserted, patterns of their orientations, and the like.

  Furthermore, although this example relates to a banknote identification apparatus, the present invention can be similarly applied to an identification apparatus that identifies paper sheets other than banknotes, such as gift certificates and coupons. .

It is a whole block diagram which shows the banknote identification device of this example. It is a functional block diagram of the control unit shown in FIG. It is a flowchart which mainly shows the setting change operation | movement of the identification specification of the banknote identification apparatus of FIG.
