Description

Description PORTABLE COUNTERFEIT-NOTE DETECTOR

Technical Field

[1] The present invention relates to a portable counterfeit-note detector. More particularly, the present invention relates to a portable counterfeit-note detector capable of improving portability thereof, preventing a risk of breakage thereof and precisely detecting a counterfeit note by employing a foldable structure.

[2]

Background Art

[3] In general, in order to prevent counterfeit note, a specific paper, which is difficult for the general public to imitate, is used. In addition, hidden illustrations, which may not appear on a copy paper, and a windowed thread, which cannot be copied on the copy paper as it is, are formed on the specific paper.

[4] In addition, counterfeit-prevention elements include specific ink or a specific printing method. An example of the counterfeit-prevention elements includes OVI (Optically Variable Ink), which changes in color depending on a viewing angle, an Intaglio Printing capable of providing persons with a specific tactile sensation when persons touches a specific portion of a paper, an Intaglio Latent Image, which is clearly exhibited when viewed in an oblique angle and is not accurately exhibited on a copy paper, and a Micro-lettering, which is not properly reproduced on a copy as it is.

[5] A portable counterfeit-note detector detects such counterfeit-prevention elements, and adapts a fluorescent detecting scheme using ultraviolet rays, a printing surface detecting scheme using a permanent magnet, and a negative print detecting scheme using white light.

[6] Conventional counterfeit-note detectors are disclosed in Korean Utility Model Registration No. 0252289 and Korean Patent Registration No. 0651245.

[7] As shown in FIG. 11, the Korean Utility Model Registration No. 0252289 represents a counterfeit-note detector using a magnet and a fluorescent light, in which an upper body 10 is coupled to a lower body 20 through a hinge 50. Grooves 12 and 22 are formed on the upper body 10 and the lower body 20, respectively. An attachment plate 30 is attached on the upper body 10. A permanent magnet 36 surrounding a steel protective cap 34 is inserted into the upper body 10. A semi-transparent screen plate 21 is installed on the lower body 20. A light source 23 and a reflective plate 24 are accommodated in a bottom portion of the semi-transparent screen plate 21. A switch 25 is formed at a side of the lower body 20.

[8] Meanwhile, as shown in FIGS. 12 and 13, the Korean Patent Registration No. 0651245 represents a portable counterfeit-note detecting device, which includes a lenticular 20 and a block body 10 including transparent material. The lenticular 20 serves as a detection member for detecting the authenticity of the note, and is provided with a plurality of lenticular lattices 23 that protrude from a base seat 21 in parallel to each other such that a latent image of a note 9 is induced to a total reflection. The block body 10 is formed at a bottom side thereof with a receiving groove having a predetermined shape corresponding to the lenticular 20 to receive the lenticular 20. A surface of a groove 13 formed on an upper surface and a lower surface of the block body 10 is curved to form a magnifying glass 15 for detecting the Micro-Lettering of the note 9.

[9] However, the conventional counterfeit-note detector has a large size, so that it is inconvenient to carry the conventional counterfeit-note detector. Since the detection member for detecting the authenticity of the note is exposed to the outside, the detection member is exposed to damage or breakage caused by external impact.

[10]

[32] FIG. 1 is an exploded perspective view representing a portable counterfeit-note detector according to a first embodiment of the present invention, FIG. 2 is a perspective view representing a bottom of the portable counterfeit-note detector shown in FIG. 1 which is withdrawn from a case, FIG. 3 is a sectional view representing the portable counterfeit-note detector shown in FIG. 1 which is withdrawn from the case, FIG. 4 is a perspective view representing the bottom of the portable counterfeit-note detector shown in FIG. 1 which is inserted into the case, and FIG. 5 is a sectional view representing the portable counterfeit-note detector shown in FIG. 1 which is inserted into the case.

[33] As shown in FIGS 1 to 5, a portable counterfeit-note detector (A) according to a first embodiment of the present invention includes a body 2, which includes a magnifying mirror 22 attached thereto, an ultraviolet LED 23, a magnet part 24, a white light LED 25 and a speaker 26, and a case 4 having a receiving part 40 in which the body 2 is received. A projection 3 is formed on the body 2. A guide groove 6 having a predetermined length is formed in the case 4 to be coupled to the projection 3. The projection 3 of the body 2 is inserted into the guide groove 6 of the case 4 in such a manner that the body 2 is slid back and forth to be withdrawn or inserted with respect to the case 4.

[34] The body 2 has a rectangular shape, and is provided at a first side thereof with the magnifying mirror 22, which allows a user to view a small-sized letter, and at a second side thereof with the magnet part 24 for detecting a printing surface having a magnetic body, the ultraviolet LED 23 for detecting a fluorescent substance of a note and the white light LED 25 for detecting a negative print of the note.

[35] An etched film, which has a plurality of polarizing particles obliquely formed thereon, is attached to the magnifying mirror 22 or the magnifying mirror 22 is partially etched in a declination angle to form a latent-image detecting part 220 such that an Intaglio Latent Image of the note is identified.

[36] The Intaglio Latent Image can be made by a counterfeit-prevention technique, in which an image is clearly viewed at an oblique viewing angle, and is not accurately shown on a copy. A person can view a specific letter made of the Intaglio Latent Image by using a polarizing lens.

[37] The body 2 is provided with the speaker 26 operating together with the magnet part

24. Accordingly, when the printing surface having the magnetic body of a normal note is detected, a predetermined sound is generated, thereby allowing a user to determine the normalcy of the note.

[38] A rechargeable battery is accommodated in the body 2, and a connecting member is installed in the body in addition to the rechargeable battery for the purpose of power supply. [39] The connecting member includes a DC (Direct Current) jack 52 directly connected to an external power outlet, a mobile phone jack 56 connected to a mobile phone and a USB (Universal Serial Bus) jack connected to a PC (Personal Computer).

[40] That is, when the rechargeable battery has been discharged, the rechargeable battery is charged through the DC jack 52. In addition, in a circumstance in which the portable counterfeit-note detector (A) cannot be connected to the power outlet, power of the mobile phone can be used by inserting the mobile phone jack 56 into the mobile phone. Further, power of the PC can be supplied to the portable counterfeit-note detector (A) through the USB jack 54.

[41] In addition, the projections 3 are projected from an outer surface of the body 2 while being spaced apart from each other.

[42] The case 4 has a rectangular shape similarly to that of the body 2 described above.

The case 4 is provided at one surface thereof with an opening, into which the body 2 is inserted, and is provided at an inner side thereof with the receiving part 40, in which the body 2 is received.

[43] The guide grooves 6 having a predetermined length are formed in the receiving part

40 such that the projection 3 of the body 2 described above is inserted into the guide groove 6. The guide groove 6 is formed while being directed toward the opening.

[44] A hook ring 41 or a through-hole 43 is formed at a read end of the case 4 such that a hand grip strap or a neck strap is connected to the hook ring 41 when the portable counterfeit-note detector (A) is used. Accordingly, a risk of losing the portable counterfeit-note detector (A) is reduced.

[45] Hereinafter, the structure and operation of the portable counterfeit-note detector (A) according to the first embodiment of the present invention will be described.

[46] If the body 2 having the magnifying mirror 22, the ultraviolet LED 23, the white light LED 25 and the speaker 26 is pushed into the receiving part 40 through the opening of the case 4, the projection 3 is inserted into the guide groove 6, so that the body 2 is assembled with the case 4.

[47] After that, if the body 2 is pulled to the outside, the projection 3 moves along the guide groove 6, so that the body 2 is withdrawn to the outside. In such a state in which the body 2 is withdrawn, the note is disposed below the body 2 for inspection.

[48] After the inspection is completed, the body 2 is pushed into the case 4 and kept in the case 4.

[49] Meanwhile, FIG. 6 is a perspective view representing a portable counterfeit-note detector according to a second embodiment of the present invention, FIG. 7 is a perspective view representing a bottom of the portable counterfeit-note detector shown in FIG. 6 which is withdrawn from a case, FIG. 8 is a sectional view representing the portable counterfeit-note detector shown in FIG. 6 which is withdrawn from the case, FIG. 9 is a perspective view representing the bottom of the portable counterfeit-note detector shown in FIG. 6 which is inserted into the case, and FIG. 10 is a sectional view representing the portable counterfeit-note detector shown in FIG. 6 which is inserted into the case.

[50] As shown in FIGS. 6 to 10, a portable counterfeit-note detector (A ) according to a second embodiment of the present invention includes a body 2, which includes a magnifying mirror 22 attached thereto, an ultraviolet LED 23, a magnet part 24, a white light LED 25 and a speaker 26, and a case 4 having a receiving part 40 in which the body 2 is received. The body 2 is hinged to the case 4 through a shaft rod 7. The body 2 moves forward and backward, so that the body is withdrawn or inserted with respect to the case 4.

[51] The body 2, the case 4 and other parts are identical to those of the first embodiment described above, so details thereof will be omitted in order to avoid redundancy.

[52] The portable counterfeit-note detector (A ) according to the second embodiment is different from the portable counterfeit-note detector (A) according to the first embodiment in that the body 2 is hinged to the case 4 through the shaft rod 7.

[53] That is, the shaft rod 7 is formed on the body 2, and a through-hole 80 to which the shaft rod 7 is coupled is formed on the case 4.

[54] An opening is formed at a side of the case 4 such that the body 2 is rotated and is inserted into the receiving part 40.

[55] A ball stopper 72 is installed to prevent the body 2 from excessively rotating, so that the body 2 is rotated only up to 180 degrees.

[56] That is, the ball stopper 72 is installed at an upper surface of the body 2 adjacent to the shaft rod 7. A guide 62 having an arc shape is recessed at an inner surface of the case 4 to guide the ball stopper 72. A first recess 821 and a second recess 822 into which the ball stopper 72 is inserted are formed at both ends of the guide 62.

[57] The ball stopper 72 includes a spring and a steel ball, and has elasticity due to the spring. Since the ball stopper 72 is generally known in the art, detailed description thereof will be omitted.

[58] In addition, a hook ring 41 or a through-hole 43 is formed at a read end of the case

4 such that a hand grip strap or a neck strap is connected to the hook ring 41 when the portable counterfeit-note detector (A ) is used. Accordingly, a risk of losing the portable counterfeit-note detector (A ) is reduced.

[59] Hereinafter, the structure and operation of the portable counterfeit-note detector (A

) according to the second embodiment of the present invention will be described.

[60] If the body 2 having the magnifying mirror 22, the ultraviolet LED 23, the white light LED 25 and the speaker 26 is pushed into the receiving part 40 through the opening of the case 4, the shaft rod 7 is inserted into the through-hole 80, and the ball stopper 72 is inserted into the first recess 821 of the guide 62, so that the body 2 is assembled with the case 4. As shown in FIGS. 7 and 8, such a state represents that the body 2 is withdrawn from the case 4. [61] After that, as shown in FIGS. 9 and 10, if the body 2 rotates in the first direction, the body 2 is inserted and received in the opening formed at one side of the case 4. [62] In this case, the ball stopper 72 is separated from the first recess 821 and moves along the guide 62 to be inserted into the second recess 822, so that the body 2 is inserted into the case 4 and fixed thereto. [63] In contrast, if the body 2 is pushed to be rotated in the second direction by 180 degrees, the body 2 is withdrawn from the case 4 and unfolded. [64] Under the state in which the body 2 is withdrawn, the note is disposed below the body 2 for inspection. [65] After the inspection has been completed, as described above, the body 2 is pushed into the inside of the case 4 such that the body 2 is inserted into the case 4 and is kept in the case 4. [66] Although few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and sprit of the invention, the scope of which is defined in the claims and their equivalents.
