The present invention relates to a medium sensing apparatus and a financial instrument.

Generally, a financial instrument is a device that automatically processes a financial task desired by a customer. The financial instrument can import or withdraw a medium (for example, banknotes, checks, securities, gift certificates, etc.), or automatically transfer the medium.

The financial instrument typically includes a media storage for storing media. In this case, the medium storage box includes a cassette for storing the medium, a recovery unit for storing the abnormal medium, and a temporary storage device for temporarily storing the medium that is introduced through the medium access unit.

At this time, the financial instrument needs to identify whether the medium to be drawn in or drawn out is a fake medium or a kind of medium if it is not a fake medium. If the medium is a forged medium, it should be returned to the customer. In case of a medium which is not falsified, it must be properly inserted into the cassette provided for each type.

Therefore, conventionally, a plurality of small magnetoresistive sensors (MR sensors), which detect magnetic components provided on the surface of the medium and have different channels, are provided in the medium conveyance path, and measurement And the medium was discriminated based on the value.

However, since the magnetoresistive sensor has poor recognition performance at both ends, it is necessary to arrange a plurality of magnetoresistive sensors so as to overlap each other in order to accurately detect the surface of the medium. Therefore, conventional financial instruments use a large number of magnetoresistive sensors, which results in a high manufacturing cost. Further, since a cable must be connected to each of the plurality of magnetoresistive sensors, the circuit configuration becomes complicated.

1 is a perspective view of a financial instrument according to an embodiment of the present invention.

Referring to FIG. 1, a financial device 1 according to an embodiment of the present invention includes a main body 10 having a plurality of parts therein. The main body 10 includes an input unit 11 for allowing a user to process a financial transaction, a check entry unit 12 for depositing a check, a paper money entry / exit unit 13 for depositing / A card entry / exit unit 14 for entering and exiting the passbook, a card entry / exit unit 15 for entering / exiting an IC card (Integrated Circuit Card) for financial processing, A medium accumulating unit 16 for storing the medium, and a medium sensing apparatus 20 (see FIG. 2) for sensing the medium.

In this specification, at least one of the check entry / exit portion 12, the bill entry / exit portion 13, the passbook entry / exit portion 14, and the card entry / exit portion 15 may be omitted. The check entry portion 12 and the paper money entry portion 13 can be collectively called media entry portions 12 and 13.

(Not shown) for temporarily storing the medium stored by the user, a recycle box (not shown) for storing the media to be deposited, a number of times the abnormal medium is stored (Not shown), a cassette (not shown) for storing a medium, and the like, and all modules that can be loaded and stored in the financial apparatus 1.

The medium sensing apparatus 20 (FIG. 2) is provided inside the main body 10 and senses the medium. The medium sensing apparatus (20 of FIG. 2) will be described in detail with reference to FIG. 2 to FIG. 5 below.

FIG. 2 and FIG. 3 are side views of a medium sensing apparatus according to an embodiment of the present invention, and FIG. 4 is a plan view of a medium sensing apparatus according to an embodiment of the present invention.

2 to 4, a medium sensing apparatus 20 according to an embodiment of the present invention includes a sensing unit frame 21, a magnetoresistance sensing unit 22, an analysis unit (not shown) A plurality of transport rollers 23, and a transport section frame 24 (frame).

The sensing unit frame 21 forms an outer appearance of the magnetoresistive sensing unit 22 and fixes the magnetoresistive sensing unit 22 at a predetermined position. Here, the predetermined position means a position where the magnetoresistive sensor 22 can sense the magnetic component 25 disposed on the surface of the medium 2 conveyed by the conveying roller 23 .

The sensing unit frame 21 may be coupled to the carrying unit frame 24 and may separate the magnetoresistive sensing unit 22 from the surface of the medium 2. This is because when the magnetoresistive sensor 22 is brought into direct contact with the surface of the medium 2, the magnetoresistive sensor 22 is disturbed by the conveyance of the medium 2.

The upper surface of the sensing unit frame 21, that is, one surface in the direction of the medium 2 may be a transparent material or an open shape. This is to allow the magnetoresistive sensor 22 to accurately detect the magnetic component 25 disposed on the medium 2. [

The magnetoresistive sensing unit 22 is provided in the sensing unit frame 21 and has a size capable of sensing at least one or more magnetic components 25 disposed on the surface of the medium 2. More specifically, the width of the magnetoresistive sensor 22 is smaller than or equal to the width of the medium 2 with respect to the entry direction of the medium 2, Component 25 may be greater than the width of the minimum plane including all of the component 25.

In this case, the magnetoresistive sensor 22 may be in the form of a line perpendicular to the entry direction of the medium 2, and may be located on the conveyance path of the medium 2. The magnetoresistive sensing unit 22 may be formed in a shape perpendicular to the direction in which the medium 2 is introduced by inserting the magnetoresistive sensing unit 22 into a magnetic component 25 disposed on the surface of the medium 2, To a size that can be detected at a time.

The magnetoresistive sensor 22 may be disposed between the plurality of conveying rollers 23. That is, the medium 2 is conveyed by the conveying roller 23, and the magnetic component 25 attached to the surface of the conveyed medium 2 is sensed by the magnetoresistive sensing unit 22. The magnetoresistive sensor 22 may be referred to as a magnetoresistive sensor.

The analysis unit (not shown) senses the medium 2 by using a measurement value sensed by the magnetoresistance sensing unit 22. The analyzing unit can determine whether the medium 2 conveyed by the plurality of conveying rollers 23 is a forged medium 2 or what kind of medium 2. [

For example, the analysis unit may measure a magnetic component 251 continuously arranged from one end to the other end of the surface of the medium 2, and at least one magnetic component 252 that is independently disposed on a part of the surface of the medium 2 , 253) can be used to determine the authenticity or type of the medium (2).

Of course, this may depend on the type of magnetic component 25 disposed on the surface of the medium 2. If the line-shaped magnetic component 251 and the plane-shaped magnetic components 252 and 253 are respectively disposed on the surface of the medium 2, the analyzer performs the analysis as described above, ) Can be distinguished.

If only the magnetic components 252 and 253 in the form of a plane are present on the surface of the medium 2, the analyzer compares the measured value of the magnetoresistive sensor 22 with respect to the magnetic components 252 and 253 The authenticity of the medium 2, and the like.

Of course, this embodiment is not limited to the magnetic component 25 disposed on the surface of the medium 2, so that the surface of the medium 2 is provided with various types of magnetic components 25, Can be arranged.

At this time, the analyzer may store a reference value that can be compared with the measured value of the magnetoresistive sensor 22 in advance. The reference value is a magnetoresistance value for various types of media (2).

That is, the analyzer compares the reference value stored in advance with the measured value of the magnetoresistive sensor 22 with respect to the medium 2 to determine whether the medium 2 is fake, . At this time, since the reference value may be different for each kind of media 2, the analyzing unit may store a plurality of reference values.

The plurality of conveying rollers 23 convey the medium 2. At least two pairs may be provided, and the magnetoresistive sensing part 22 may be disposed between the two pairs of conveying rollers 23 as described above. That is, a pair of conveying rollers 23 may be provided in front of the magnetoresistive sensor 22, and a pair of conveyor rollers 23 may be provided behind the magnetoresistive sensor 22.

The magnetic component 25 disposed on the surface of the medium 2 to be transported may be measured by the magnetoresistive sensor 22, .

The medium 2 conveyed by the plurality of conveying rollers 23 may be different in the front-back direction from one medium 2 to another. That is, the magnetoresistive sensor 22 may not face the surface of the medium 2 on which the magnetic component 25 is disposed. However, since the magnetoresistance is a value that can be sensed even if it is in direct contact with or not in contact with the medium 2, the magnetoresistive sensor 22 can smoothly detect the magnetic component 25 Can be detected.

The conveying section frame 24 fixes the plurality of conveying rollers 23 so that a part of the conveying rollers 23 is exposed to the outside. Exposure of the plurality of conveyance rollers 23 to the outside is performed so that the medium 2 is brought into contact with the conveyance roller 23 and conveyed.

At this time, the sensing unit frame 21 may be coupled to the carrying unit frame 24 as described above. The upper surface of the sensing unit frame 21 may coincide with the upper surface of the transport unit frame 24.

A plurality of roller shafts 231 serving as rotation centers of the plurality of conveyance rollers 23 may be provided in the conveyance section frame 24 and a driving source (Not shown).

The plurality of conveying rollers 23 and the conveying section frame 24 may be called conveying sections 23 and 24. Of course, the conveying units 23 and 24 may include both the roller shaft 231 and the driving source.

FIG. 5 is a diagram illustrating measured values of a magnetoresistive sensor of a medium sensing apparatus according to an exemplary embodiment of the present invention. Referring to FIG.

4 and 5, a line-shaped magnetic component 251 may be disposed on a center portion of the surface of the medium 2, and a magnetic component 251 may be disposed on the left and right sides of the line- Shaped magnetic components 252 and 253 may be provided.

Since the magneto-resistive sensing unit 22 has a size capable of sensing all of the magnetic components 25 disposed on the surface of the medium 2, All of the magnetic components 252 and 253 can be detected. Of course, the sensing time may vary depending on the position of the magnetic component 25.

The values measured by the magnetoresistance sensing unit 22 may be shown in a graph of the concavo-convex shape as shown in FIG. At this time, the entry point of the medium 2 is when one end of the medium 2 conveyed by the conveying roller 23 reaches the magnetoresistive sensor 22, And the other end of the magnetoresistive sensor 2 is out of the magnetoresistive sensor 22.

5, since the line-shaped magnetic component 251 disposed on the surface of the medium 2 immediately after the entry of the medium 2 is continuously detected by the magnetoresistive sensor 22 , A continuous measurement value is displayed. At this time, the measured values continuously appear from the entry point of the medium (2) to the entry point of the medium (2). This is because the line-shaped magnetic components 251 described above are continuously arranged from one end of the medium 2 to the other end.

4, the magnetic component 252 displayed on the left side of the surface of the medium 2 is first detected by the magnetoresistive sensing part 22. [ Therefore, since the total measured value of the magnetoresistance is represented by the sum of the measured values for the magnetic component 252 in the form of a line and the measured value for the linear shaped magnetic component 251, Respectively.

The magnetic component 252 displayed on the left side of the surface of the medium 2 in Fig. 4 is no longer detected by the magnetoresistive sensing part 22. Fig. Therefore, the magnetoresistance measurement value returns to the measured value of the line-shaped magnetic component 251 again.

Next, in FIG. 4, the magnetic component 253 displayed on the right side of the surface of the medium 2 can be detected by the magnetoresistive sensing part 22. FIG. At this time, the magnetoresistance measurement value again rises.

The right magnetic component 253 also deviates from the magnetoresistive sensing part 22 by the transportation of the medium 2. [ Therefore, the magnetoresistance measurement value is returned to the measurement value obtained by measuring only the line-shaped magnetic component 251 disposed on the surface of the medium (2).

When the other end of the medium 2 passes through the magnetoresistive sensing part 22, the magnetic component 25 disposed on the surface of the medium 2 is not sensed by the magnetoresistive sensing part 22. Therefore, the graph of FIG. 5 returns to the initial value.

Thus, by comparing the unevenness graph measured by the magnetoresistance sensor 22 with the reference value of the analyzer, the present embodiment can determine whether the medium 2 conveyed by the conveying roller 23 is true or false, Can be clearly grasped.

Also, since the present embodiment can accurately discriminate the medium 2 by using only one magnetoresistive sensor 22, the configuration can be simplified and the manufacturing cost can be reduced.
