Description

  The present invention relates to an identification sensor capable of identifying an object with high accuracy regardless of the type of the object, and in particular, not only identifying a banknote as an object with high accuracy, but also, for example, a ticket with a barcode. The present invention relates to an identification sensor capable of accurately identifying a barcode of the barcode.

Conventionally, as this type of identification sensor, for example, as shown in Patent Document 1, a barcode sensor equipped with a magnetic sensor for identifying a banknote and an optical sensor for identifying a ticket with a barcode is provided. A banknote discriminating apparatus is known.
This device is adapted to perform an identification process according to the type of object. First, regardless of the type of object, the printing unit of the object (for example, on the surface of banknotes) The presence or absence of magnetic components of printed patterns such as printed characters and figures and various designs on the surface of a ticket with a barcode are detected. At this time, when the magnetic sensor detects a magnetic component in the printing part of the object, the object is recognized as a banknote, and the authenticity of the banknote is determined based on the detection result of the magnetic sensor. On the other hand, when the magnetic sensor does not detect the magnetic component in the printing part of the object, it recognizes that the object is a ticket with a barcode, and the barcode information is detected from the barcode by the optical sensor. .

However, the conventional identification sensor requires a magnetic sensor for identifying banknotes and an optical sensor for identifying a ticket with a barcode separately. The complexity increases and the manufacturing cost also increases.
When optically sensing a barcode, for example, as shown in FIG. 2 (b), the condensing spot P of the sensing light condensed on the barcode from the optical sensor has a plurality of types constituting the barcode. It will be formed across the bar. In this case, light from the individual bars is mixed especially in a place where the bars are densely packed, and the same optical characteristics as the light from one thick bar are exhibited. The sensing data obtained at this time does not have a rectangular wave-like data characteristic corresponding to the barcode shape as shown in FIG. 2C, for example, but has an ambiguous data characteristic as shown in FIG. Play. As a result, the barcode information cannot be detected accurately.
JP-A-6-325240

  The present invention has been made to solve such a problem, and the object thereof is to identify the object with high accuracy regardless of the type of the object, and particularly as the object. An object of the present invention is to provide an identification sensor that can not only accurately identify a banknote but also accurately identify a bar code when identifying a ticket with a bar code, for example.

In order to achieve such an object, the present invention discriminates an object by optically sensing the surface structure 6 applied to the surface of the object when scanned along the surface of the object. The identification sensor 2 is provided with a plurality of optical elements 10. In this case, the plurality of optical elements include an identification information acquisition unit (for example, all the optical elements 10) that optically senses the surface configuration and acquires object information for identifying the object, and a plurality of types of bars. A barcode information acquisition unit that optically senses a barcode and obtains the barcode information when the barcode 8 to which various barcode information is given by a combination of a space and a space is included in the surface configuration ( For example, the identification information acquisition unit includes the plurality of optical elements, and the barcode information acquisition unit selects a specific optical element from the plurality of optical elements. When optically sensing the surface configuration, all optical elements are selected and function as one sensor, and when optically sensing a barcode, one light Select academic elements.
Further, the present invention is an identification device including an identification sensor for identifying an object by optically sensing a surface configuration applied to the surface of the object when scanned along the surface of the object. The identification sensor is provided with a plurality of optical elements. In this case, the plurality of optical elements includes various types of bars by combining an identification information acquisition unit that optically senses the surface configuration and acquires object information for identifying an object, and a plurality of types of bars and spaces. When the barcode to which the code information is added is included in the surface configuration, the barcode information is obtained by optically sensing the barcode and acquiring the barcode information. On the other hand, the identification device selects a plurality of optical elements constituting the identification information acquisition unit from among the plurality of optical elements according to the type of surface configuration, or a specific optical element constituting the barcode information acquisition unit. The optical element selection means 14 to be selected, the specific optical element selected by the optical element selection means, the optical element control means 16 for optically sensing the surface configuration of the object, and the optical element control means Predetermined calculation processing is performed on the electrical signal output from the specific optical element to calculate the object information or barcode information, the object information or barcode information calculated by the calculation means, and the ROM 24 in advance. by comparing the registered sample information, and a comparison discriminating means 20 for identifying an object, the optical element selection means, in the case of optically sensing the surface structure, Select optical element to function as a single sensor Te, when optically sensing the bar code selects one of the optical elements.
In this case, each of the plurality of optical elements has a light emitting unit 12a that emits predetermined sensing light toward the surface configuration of the target object, and a surface configuration of the target object when the predetermined sensing light is emitted from the light emitting unit. And a light receiving portion 12b for receiving the generated light. In this configuration, the sensing area of the specific optical element in the barcode information acquisition unit is formed on the surface configuration so as not to straddle a plurality of types of bars and spaces constituting the barcode.
The light generated from the surface configuration of the object includes reflected light R reflected from the surface configuration of the object and transmitted light T transmitted through the surface configuration of the object. A printed pattern such as characters and figures printed on the surface of the banknote, and a barcode printed on a cashout ticket (ticket with a barcode) used at a game facility, for example, are included.

  According to the present invention, it is possible to identify the object with high accuracy regardless of the type of the object, and in particular, not only to identify the object (for example, banknote) with high accuracy, It is possible to provide an identification sensor capable of accurately acquiring a barcode attached to an object.

Hereinafter, an identification sensor and an identification device according to an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1A shows an external configuration of an identification apparatus in which the identification sensor 2 according to the present embodiment is incorporated. In this case, when the identification sensor 2 scans along the surface of the object, the object can be identified by optically sensing the surface configuration 6 of the object. Here, it is assumed that the object is a banknote 4a (FIG. 1 (b)) or a cash-out ticket 4b (FIG. 1 (c)), and characters and figures printed on the surface of the banknote 4a or the cash-out ticket 4b are used. A printing pattern, a barcode 8 and the like are defined as the surface configuration 6. The cash-out ticket 4b is a ticket printed out from a coinless machine (not shown) at the game facility, and the amount is written in the barcode 8 instead of paying out with coins.

The identification sensor 2 is arranged in a plurality of locations so as to be sensed (scanned) along the characteristic part of the object (the bill 4a or the cash-out ticket 4b). For example, in FIG. 1A, a plurality of identification sensors 2 are arranged at predetermined intervals along a direction (short direction) that crosses the longitudinal direction of the bill 4 a that is an object, and sensing is performed in the longitudinal direction of the bill 4. In addition to this, for example, a plurality of identification sensors 2 may be arranged at predetermined intervals along the longitudinal direction of the banknote 4, and sensing may be performed in the short side direction of the banknote 4.
Note that the arrangement interval and the number of the identification sensors 2 are arbitrarily set according to the shape and position of the characteristic part of the object (the banknote 4a or the cash-out ticket 4b). Is not particularly limited. The characteristic part of the object is a part effective for determining and identifying the banknote 4a or the cash-out ticket 4b (for example, among the surface structures 6, the characteristic of the banknote 4a or the cash-out ticket 4b is best). Pointed to).

  Further, as a method of scanning the plurality of identification sensors 2 along the characteristic portion of the object (banknote 4a or cash-out ticket 4b), for example, as shown in FIG. 1A, each identification sensor 2 is indicated by an arrow S1. Although the method of moving along the scanning direction and the method of moving the banknote 4 along the scanning direction shown by arrow S2 can be considered, here, as an example, a method of moving each identification sensor 2 in the scanning direction S1. Adopted (FIGS. 1B and 1C). In any method, since an existing moving device can be used as a means for moving each identification sensor 2 or object (banknote 4a or cash-out ticket 4b), description thereof is omitted. In this case, the timing of moving each identification sensor 2 is generally a method of moving each identification sensor 2 at the same time, but is not limited to this, and the movement timing of each identification sensor 2 is individually set. You may apply the method of controlling and moving relatively shifted.

As shown in FIGS. 1A to 1E, each identification sensor 2 includes a plurality of optical elements 10 in the scanning direction S1 in which a wide sensing area W in the direction crossing the scanning direction S1 is secured. They are provided adjacent to each other.
In the present embodiment, as an example, ten optical elements 10 are applied, and these optical elements 10 optically sense the surface configuration 6 and target objects (banknotes 4a or cash-out tickets 4b). When the surface configuration 6 includes an identification information acquisition unit for acquiring object information for identifying the object and a barcode 8 to which various types of barcode information are given by a combination of a plurality of types of bars and spaces. And a barcode information acquisition unit that optically senses the barcode 8 to acquire barcode information.

  Here, the object information is identification information for identifying, for example, the banknote 4a or the cash-out ticket 4b, and based on the identification information, for example, the authenticity of the banknote 4a or the cash-out ticket 4b can be determined. . Further, the barcode information is, for example, identification information for specifying the payout amount of the cash-out ticket 4b. Based on the identification information, the authenticity of the barcode 8 is determined. Payment of the amount according to the barcode information can be received.

  Further, the identification information acquisition unit is composed of ten optical elements 10, and each of the optical elements 10 receives the light generated from the surface configuration 6 of the target (banknote 4 a or cash-out ticket 4 b), whereby the target Material information can be acquired. The barcode information acquisition unit is configured by selecting a specific optical element (for example, one optical element indicated by reference numeral 10a in FIG. 1C) from the ten optical elements 10, and The bar code information can be acquired by receiving light from the bar code 8 with the individual optical elements 10a.

  In this case, each optical element 10 includes a light emitting unit 12a that emits predetermined sensing light L toward the object (surface configuration 6), and an object (when the predetermined sensing light L is emitted from the light emitting unit 12a). The light receiving portion 12b for receiving the light R generated from the surface configuration 6) may be provided (FIG. 1D), or each optical element 10 may be constituted by only the light receiving portion 12b (see FIG. 1D). FIG. 1 (e)). In addition, as each optical element 10, what is marketed can be utilized if the wide sensing area | region W is securable, For example, a semiconductor laser, a light emitting diode, etc. should just be applied as the light emission part 12a. For example, a photodiode or a phototransistor may be applied as the light receiving unit 12b.

  Here, the predetermined sensing light L is assumed to be light having a predetermined frequency emitted from the light emitting unit 12a when, for example, a semiconductor laser or a light emitting diode is used for the light emitting unit 12a. On the other hand, the light R generated from the surface configuration 6 of the target object assumes the reflected light R reflected from the target object (surface configuration 6). It has different optical characteristics (light intensity change, scattering, wavelength change, etc.) depending on the position and the type of ink (for example, magnetic ink) used for printing the surface configuration 6 and the density. In addition, when each optical element 10 is comprised only by the light-receiving part 12b, the reflected light R is the light reflected from the target object (surface structure 6), for example with natural light or the light from a room light.

  Thus, even when the surface structure 6 of the object (banknote 4a or cash-out ticket 4b) is printed out of alignment by securing a wide sensing area W in each optical element 10 of the identification sensor 2, the printing is performed. As long as the deviation does not exceed the sensing area W, the object can be identified with high accuracy by optically sensing the characteristic portion of the object (surface structure 6) without being affected by the printing deviation.

  Further, when an identification information acquisition unit is configured by each optical element 10 (in this embodiment, as an example, when all the optical elements 10 configure the identification information acquisition unit), the sensing region W is set to 10 in the scanning direction S1. The surface configuration 6 is sensed in the doubled region. According to this, since the same effect as when the ten optical elements 10 are collectively functioned as one sensor is exhibited, even if there is a printing misalignment, a wide range of object information covering it can be obtained. It can be acquired. As a result, the object can be identified with high accuracy.

  Furthermore, when a specific optical element (for example, one optical element indicated by reference numeral 10a in FIG. 1C) is selected from the ten optical elements 10 and the barcode information acquisition unit is configured, the identification is performed. Since the sensing region W of the optical element 10a does not straddle a plurality of types of bars and spaces constituting the barcode 8, as shown in FIG. 2B, for example, the plurality of types of bars and spaces are individually separated. Sensing is possible. In this case, the obtained bar code information does not have the ambiguous data characteristic (FIG. 2 (d)) as in the prior art, but, for example, the data characteristic corresponding to the bar code shape as shown in FIG. 2 (c). Become. As a result, the barcode information can be detected accurately.

Next, referring to the attached drawings, the configuration and operation for identifying the authenticity of the object (banknote 4a or cash-out ticket 4b) and the authenticity of the barcode 8 by incorporating the identification sensor 2 as described above into the identification device. I will explain.
As shown in FIGS. 1 (a) and 1 (f), the identification device according to the present embodiment includes the above-described identification information acquisition unit among ten optical elements 10 according to the type of the surface configuration 6 of the object. Or the optical element selection means 14 which selects the specific optical element (for example, all the optical elements 10 or one optical element 10a) which comprises a barcode information acquisition part, and the specific optical selected by the optical element selection means 14 An optical element control means 16 for optically scanning the surface structure 6 of the object by controlling the elements, and a predetermined arithmetic processing is performed on the electrical signal output from the specific optical element controlled by the optical element control means 16. The calculation means 18 for calculating the object information or barcode information described above, the object information or barcode information calculated by the calculation means 18 and the sample information registered in advance are compared to identify the object ( For example, banknote 4a or Authenticity of cash out ticket 4b, and a comparison discriminating means 20 such as the identification) to authenticity of the barcode 8.
The optical element selection unit 14, the optical element control unit 16, the calculation unit 18, and the comparison identification unit 20 are accommodated in the control unit 22.

  The optical element selection unit 14 selects an optical element to be operated according to the type of the surface configuration 6 of the object. For example, when identifying the banknote 4a, all the optical elements 10 are selected. For example, when identifying the cashout ticket 4b, one optical element 10a for identifying the barcode 8 (the optical element 10a at the most downstream position in the scanning direction S1) is selected. . When identifying the cash-out ticket 4b, each identification sensor 2 that senses the surface configuration 6 other than the barcode 8 selects the ten optical elements 10 to function as one sensor. This selection example is merely an example, and the number and position of the optical elements 10 are arbitrarily selected according to the type of the surface configuration 6 of the object.

When each optical element 10 receives the reflected light R reflected from the object (surface structure 6), each optical element 10 outputs an electrical signal (for example, voltage) having an intensity corresponding to the amount of received light from the light receiving unit 12b. It is like that. In this case, the output voltage output from the light receiving unit 12b of each optical element 10 is proportional to the amount of received light. The output voltage increases as the amount of received light increases, and the output voltage decreases as the amount of received light decreases.
The reflected light R reflected from the surface configuration 6 of the object (banknote 4a or cash-out ticket 4b) is the shape and position of the surface configuration 6 and the type of ink used for printing the surface configuration 6 (for example, in the banknote 4a). Different optical characteristics (change in light intensity, scattering, wavelength change, etc.) appear depending on the type of magnetic ink) and the density, and the amount of reflected light R increases or decreases depending on the optical characteristics. As the amount of the reflected light R changes in this way, the output voltage (signal level [V] of the electrical signal) output from the light receiving unit 12b of each optical element 10 also changes.

The operation of the identification device incorporating the identification sensor 2 will be described below.
In this operation description, the operation for identifying the authenticity of the banknote 4a will be described, while the operation for reading the barcode information of the barcode 8 will be described for the cashout ticket 4b.
First, before performing the actual identification process, pre-scanning is performed to optically sense the surface configuration 6 of the sample object (genuine banknote), and the sample information (sample object information) obtained at that time is identified. It is registered in a ROM (Read Only Memory) 24 of the (control unit 22).

  Specifically, a large number (for example, several hundred) of sample objects (genuine banknotes) are prepared, and each sample object is set one by one in an identification device as shown in FIG. Sample information (sample object information) is acquired by each identification sensor 2 for each object. The sample information obtained at this time is registered as data information having a certain width in accordance with, for example, printing displacement of the surface structure 6 of the object as shown in FIG. The sample information is obtained by plotting all electric signals output from each identification sensor 2 (the light receiving unit 12b of each optical element 10). In this case, an area between the maximum line M1 formed by connecting the maximum values of the sample information and the minimum line M2 formed by connecting the minimum values is defined as an allowable range.

  Thereafter, in the actual identification process, it is compared whether or not the electrical signal from each optical element 10 (light receiving unit 12b) is within the allowable range of the sample information (sample target information) registered in the ROM 24 in advance. Thus, the authenticity of the object (banknote 4a) is identified. Further, the barcode information of the barcode 8 is read based on the electrical signal from the specific optical element 10a (the light receiving unit 12b) that senses the barcode 8. Note that the barcode information includes, for example, information obtained by converting the amount of money acquired by various gaming machines into a barcode.

  Here, if the object (banknote 4a) is authentic, the electrical signal from the optical element 10 is plotted along the region (allowable range) between the maximum line M1 and the minimum line M2 (FIG. 2 (a)). Dotted line). On the other hand, if the electric signal from the optical element 10 deviates from the allowable range, the object (banknote 4a) is identified as a basket. The reflected light R generated from the surface structure 6 of the object appears with different optical characteristics (change in light amount) between the new and old bills, but the difference in the light amount of the reflected light R (that is, the difference in the intensity of the electrical signal). ) Is not so different between new and old bills. Therefore, since it is not necessary to increase the width between the maximum line M1 and the minimum line M2 of the sample information detected in advance, the identification accuracy can be improved.

  Specifically, first, the optical element selection means 14 selects the optical element 10 to be operated according to the type of the object (banknote 4a). That is, if the object to be identified is a bill 4a, all the optical elements 10 of each identification sensor 2 are selected, and if the object to be identified is a cash-out ticket 4b, an identification sensor that senses the bar code 8 2 one optical element 10a is selected. In this case, each of the identification sensors 2 other than the identification sensor 2 that senses the barcode 8 may select the ten optical elements 10 and sense a portion other than the barcode 8.

  Subsequently, the optical element control means 16 controls the specific optical element selected by the optical element selection means 14 to optically scan the surface configuration 6 of the object. In this case, if the object is a bill 4a, the specific optical element is all the optical elements 10 of each identification sensor 2, and if the object is a cash-out ticket 4b, the specific optical element is a barcode 8 It becomes one optical element 10a of the identification sensor 2 that senses.

At this time, the electrical signal output from the specific optical element (10, 10a) controlled by the optical element control means 16 is subjected to predetermined arithmetic processing by the arithmetic means 18, and the above-described object information or bar code information and Is calculated.
Here, a method for calculating the object information will be briefly described.
In the present embodiment, as one example, since ten optical elements 10 (light receiving units 12b) of the identification sensor 2 are operated, ten different electrical signals are output from the ten light receiving units 12b. By the way, since the ten light receiving elements 10 are adjacent to each other along the scanning direction S1, the ten electric signals output from the ten light receiving elements 10 are expected to have approximate values. Therefore, if an average value obtained by dividing the total value of 10 electrical signals (the total value of electrical signal levels) by 10 (the number of optical elements) is calculated, the calculation result is 10 optical elements 10. Can be regarded as being equivalent to one electrical signal obtained when configured as one optical element.
Note that this calculation method is merely an example, and other calculation methods may be applied as long as equivalent object information can be calculated.
On the other hand, the electric signal from one optical element 10a controlled by the optical element control means 16 is subjected to predetermined calculation processing by the calculation means 18, so that, for example, a bar code representing the amount of money acquired by various gaming machines. Calculated as information. Then, based on the calculated barcode information, it is possible to receive money (banknotes and coins) according to the amount of money acquired from a payout device (not shown).

Further, the object information calculated by the calculation means 18 is compared with sample information (sample object information) registered in advance in the ROM 24 by the comparison and identification means 20.
In this case, if the object is a banknote 4a, the object information is compared with the sample object information, and if the object information is within the allowable range of FIG. 2A (dotted line in the figure), the object An object (banknote 4a) is identified as authentic, and if the object information deviates from the allowable range in FIG. 2 (a), the object (banknote 4a) is identified as a bag. Is done.

  According to such identification processing, by selecting a specific optical element 10 (an optical element in which the sensing area W is widened) by the optical element selection unit 14, in addition to the identification of the object by the common identification sensor 2. Thus, the barcode 8 can be identified. For example, in order to identify the authenticity of the object (banknote 4a), for example, all the optical elements 10 may be selected by the optical element selection means 14, and these may be collectively controlled as one identification sensor 2.

When the barcode 8 is identified, for example, one optical element 10a is selected by the optical element selection means 14, and the identification sensor 2 is moved along the barcode 8 in a state where only the optical element 10a is operated. It only has to be sensed.
In this case, as shown in FIG. 2B, the sensing region W of one optical element 10a is not formed across a plurality of types of bars and spaces constituting the barcode 8, but a plurality of types. Bars and spaces can be individually sensed. Explaining with a specific example, the width dimension in the scanning direction S1 of the sensing region W of one optical element 10a is smaller than the narrowest interval among the plurality of types of bars constituting the barcode 8, for example. A slightly smaller width dimension (for example, approximately 0.4 mm) may be set. By setting to such a width dimension, the sensing region W of one optical element 10 a is not formed across a plurality of types of bars and spaces constituting the barcode 8.

  By the way, in the conventional sensor, the condensing spot P of the sensing light condensed on the barcode 8 is formed across a plurality of types of bars and spaces constituting the barcode. In particular, in places where bars are densely packed, light from individual bars is mixed, and optical characteristics similar to light from a single wide bar are exhibited. The barcode information obtained at this time does not have the data characteristic that matches the rectangular barcode shape as shown in FIG. 2 (c), for example, and the ambiguous data as shown in FIG. 2 (d). Has characteristics. In this case, since the barcode information cannot be obtained accurately, for example, it may not be possible to receive payment of money (banknotes or coins) according to the amount of money acquired at the time of gaming.

  On the other hand, according to the present embodiment, the barcode information obtained from the sensing region W of one optical element 10a has data characteristics that match a rectangular barcode shape as shown in FIG. It becomes. In this case, since the barcode information can be obtained accurately, for example, money (banknotes or coins) according to the amount of money acquired at the time of gaming can be reliably received.

In the above-described embodiment, the example of the identification sensor 2 using the reflected light R has been described. However, the present invention is not limited to this example. For example, as shown in FIGS. It can also be set as the identification sensor 2 using the light T. In this case, for example, the identification sensors 2 are arranged to face each other with the object (4a, 4b) interposed therebetween so that the light emitting unit 12a and the light receiving unit 12b face each other. Thereby, the sensing light (transmitted light) T from the light emitting unit 8a of one identification sensor 2 is transmitted through the object (4a, 4b) and then received by the light receiving unit 8b of the other identification sensor 2. In the case of such a transmissive type, the objects (4a, 4b) are limited to those having optical transparency.
In addition, the figure (a) has shown the control state of the transmitted light T at the time of acquiring target object information, The figure (b) shows the control state of the transmitted light T at the time of acquiring barcode information. Show.

  In the above-described embodiment, the light emission timing and light emission wavelength of the light emitting unit 12a of the identification sensor 2 are not particularly described. However, the light emission timing and light emission wavelength can be arbitrarily set by the control unit 22 of the identification device. It is. For example, it is possible to control so that sensing light L (near infrared light, visible light) in different wavelength bands is individually emitted (alternately emitted at a predetermined timing). In this case, one of the sensing lights L in different wavelength bands is set to a wavelength band (near infrared light) of approximately 700 nm to 1600 nm, and the other is set to a wavelength band (visible light) of approximately 380 nm to 700 nm. It is preferable to do.

  In the above-described embodiment, the bill 4a or the cash-out ticket 4b is applied as an object. However, the present invention is not limited to this. For example, a semiconductor substrate on which a fine integrated circuit is printed is used as an object. It is also possible to apply as. The surface structure 6 in this case is a pattern printed integrated circuit. According to such a configuration, since the integrated circuit 6 can be identified with high accuracy, the yield of products can be improved.

  In the above-described embodiment, the barcode 8 formed by combining a plurality of types of bars and spaces has been exemplified. However, the present invention is not limited to this. For example, a “QR (Quick Response) code” as a two-dimensional code is used. Needless to say, etc. are also applicable.

  The present invention not only identifies banknotes and cash-out tickets, but also determines the authenticity of, for example, prepaid cards and securities, or the accuracy of complex circuit patterns applied on a semiconductor wafer in the technical field of semiconductor wafers, for example. It can also be used as a determination device for determining the yield and the like.
