In addition, the loading sensor 140 is Detecting the state information in the cassette 100 of the loaded security paper 110, such as the weight or height of the loaded security paper 110 will be.

In addition, the stacking sensor unit 140 is a measurement that can distinguish whether the security paper 110 or general paper as input information of the sensor added to the side of the cassette 100 or whether the general paper is partially included, etc. Sensing information

Thus, as shown in Figure 5, the outer surface or the inner surface of the security paper 110 accommodated in the cassette 100 of the present invention is provided with a predetermined pattern or pattern by a method such as printing, coating or attaching the loading sensor unit ( 140 can be configured at the same time the security paper detection sensor 120 and the loading sensor unit 140 in the cassette 100 for receiving the security paper 110 to detect the security paper sensor 120. In addition, the security paper 110, the detection mark 150 and the side detection mark 150-1 may be configured on the upper and side surfaces of the security paper 110, respectively.

At this time, the sensing control unit 120 is connected via the input and output data transmitted to the sensors of the sensor sensor 120 and the loading sensor 140, the sensing control unit configured to the CPU to control the selection use of the cassette 100 in the paper feed state ( 160).

The detection control unit 160 transmits a signal or information to the control device of the copier in response to the detection signals of the security paper detection sensor unit 120 and the loading sensor unit 140.

The detection control unit 160 transmits a signal or information to the control device of the copier in accordance with determining whether the security paper 110 or the general paper received from the security paper detection sensor 120 and the loading sensor 140. .

As such, the security paper detection sensor unit 120 and the stacking sensor unit 140 are installed inside the cassette 100, and the security paper loaded in the cassette 100 before the security paper 110 is supplied by the copier. The detection mark 150 is included in the security paper 110 by analyzing a signal received by firing an electromagnetic signal or an optical signal on the 110 or a change amount signal of the electric field or the magnetic field of the detection mark 150. Sense

The security paper detection sensor unit 120 and the loading sensor unit 140 has a detection mark on the paper when the security paper 110 signal is input from the light receiving unit of each sensor before the security paper 110 is transported on the cassette 100. 150 and the side detection mark 150-1 are determined to be present, and if the input signal is not input from the light receiving unit, the security mark 110 includes the detection mark 150 and the side detection mark 150-1. We do not judge.

At this time, if the detection mark 150 and the side detection mark 150-1 material is not included in the security paper 110, the security paper detection sensor unit 120 and the loading sensor unit 140 detects this, At the same time as the operation of the copier is stopped by the sensing controller 160, an alarm is generated from the sensing controller 160. While plain paper is not removed from the cassette 100, an alarm is continuously generated and the copier does not operate.

On the other hand, when describing the detection mark 150 and the side detection mark 150-1 attached or applied to the security paper 110, when the magnetic material of the detection mark 150 made of amorphous alloy (amorphous soft magnetic Alloy) as a detection tag, and a predetermined pattern or pattern is attached to the upper outer surface of the security paper 110.

It is vacuum-deposited or transferred to one surface of the metal thin film which is a magnetic material of the security paper 110.

As such, the security paper 110 including the detection mark 150 and the side detection mark 150-1 is attached or applied to the security paper 110 according to a discrimination method such as MR, GMR, MI, GMI, EM, and the like. The security paper sensor 120 and the load sensor 140 detect a change component such as resistance, impedance, frequency phase and amplitude according to the change of the magnetic field property of the tag for detection.

In addition, by the magnetic flux generated from the tag medium for detecting the security paper 110, the security paper detection sensor 120 and the loading sensor 140, which is a sensing device, detects a change in magnetic flux. Induced electromotive force (faraday law) induces electromotive force in the sensing device.

In other words, the magnetic properties of the tag media are converted into electrical output through the sensing device.

In addition, differentiation-type magneto-resistive (MR) and GMR (Giant MR) use the magnetoresistance of the magnetic properties of the magnetic medium as a sensor element of the sensing device.

In other words, an element whose resistance changes according to the change of magnetic flux (this is called an MR element) is used. Such an MR element uses a large magnetoresistive MR (GMR) element having a large magnetoresistance ratio. The magnetoresistance phenomenon is observed in most metal thin films. The most important point is that the resistance of the metal film depends on the direction of magnetization. Specifically, if the direction of the current is the same as the direction of magnetization, the resistance is large, and if the direction of the current and the direction of the magnetization is perpendicular, the resistance is small.

This change in resistance occurs because scattering of electrons at the magnetic nonmagnetic interface depends on the direction of magnetization.

And the characteristic of MR technology is to measure the magnetic flux directly. Therefore, the output is almost independent of the linear velocity of the detection tag inserted in the paper, and since the power is used as the active device, the output increases as the sensing current increases.

In addition, the differential type MI and GMI have an impedance when the high-frequency current is energized by the ferromagnetic material depending on the external magnetic field.

That is, when a high frequency alternating current is supplied to the soft magnetic material, the impedance is changed by the skin effect of the magnetic material.

Therefore, when the magnitude of the voltage is measured at both ends of the magnetic material while energizing a high frequency constant current, it changes according to a magnetic field applied from the outside. The magnetic field can be detected by converting the voltage into a magnetic field. An element that detects a magnetic field using such a phenomenon is called a magneto-impedance (MI) effect element.

Here, the magnetic impedance effect refers to an electromagnetic phenomenon in which the impedance is changed at high sensitivity by an external magnetic field when a high frequency current or a pulse current flows by generating an epidermal effect on the magnetic material.

In addition, since the MI sensor performs a high frequency modulation operation, the response speed is remarkably high, and the conduction current is very low, which may be used in combination with a semiconductor device.

In addition, the differential type EM (Electro Magnetic) and AM (Acoustic Magnetic) are technologies using frequency change characteristics according to the change of the magnetic field properties, where the EM (electro magnetic) is a harmonic sensor and magneto elastic (ME). ) It is divided into two kinds of sensors.

Harmonic sensors mainly use Co-based (A, B, Si, etc.) amorphous soft magnetic alloy amorphous ribbons, which generate a change in magnetic properties clearly distinguished at specific frequencies through an appropriate heat treatment process. In the specific magnetic field region, the characteristic that changes according to the time change of the external magnetic field is to detect the electrical change value in the pick-up coil.

In this principle, when the paper equipped with the harmonic sensor passes through the detection system of the present invention, it is detected and applied to discriminating whether or not the security paper 110 is used.

The material of the tag for detection mounted in the security paper 110 changes the magnetization direction therein and accordingly resonates according to an external signal. At this time, the detection unit detects a voltage change added to the reference signal pulse to detect the security paper ( 110).

That is, the EM method detects and detects harmonics generated by alternating alternating magnetic fields in the monitoring area when soft magnetic material (metal) is placed in the alternating magnetic field.

On the other hand, it is possible to apply techniques for detecting a change in the magnetic characteristics or the resulting electrical characteristics due to the external signal of the amorphous soft magnetic alloy mounted on the security paper 110.

Next, a paper may be used that is attached to the surface of the security paper 110 invisible to the special material. In this case, optical sensing is mainly used.

Such, the security paper 110 is loaded on the cassette 100 of the present invention and the detection mark 150 attached to the loaded security paper 110 is loaded security unit 140 is attached to the detection mark 150 security While making contact with the side of the paper 110, it detects the state information in the cassette 100 of the loaded security paper 110, such as the weight of the loaded security paper 110 or the loading height.

In addition, the security paper sensor unit 120 configured in the cassette 100 is individually or in a statistical manner such as pattern recognition with respect to the paper being transferred to the paper feed path 12 among the papers loaded in the cassette 100. The security paper 110 and the general paper will be distinguished.

In addition, the cassette 100 having the security paper detection sensor unit 120 or the stack sensor unit 140 can be mounted on the existing printing apparatus 10 to be used.

In this way, the security paper 110 by determining whether the security paper 110 by the security paper sensor 120 and the loading sensor 140 configured in the cassette 100 for receiving the security paper 110, the security paper 110 The copy or print supply will be made only when confirmed.

In addition, the security paper 110 may be identified to selectively supply only the security paper 110 to the security paper 110 in a device that requires the supply of a paper such as a copy machine, a printer, a fax machine, or the like. .

Such a security printing paper discriminating apparatus of the present invention may prohibit recording by recognizing whether or not the paper to be moved to the recording unit of the printing apparatus 10 is the security paper 110 before printing is started.

In addition, the distinction between the security paper 110 of the printing apparatus 10 generates a signal prohibiting secondary recording through the security paper sensor 120 and the loading sensor 140 to provide thorough security.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various modifications and variations are possible within the scope of the appended claims.
