Description

  The present invention relates to a paper sheet discriminator, and in particular, determines whether or not there is a watermark applied to a paper sheet by using light from the standing plate that illuminates and illuminates the light by illuminating the cross section of the standing plate. Related to the paper sheet discriminator.

  In recent years, many sophisticated counterfeit bills have been available. These are made using a home computer or a color copier with improved performance, and when such counterfeit bills are used, it is difficult to immediately determine whether they are counterfeit bills or true bills.

  In view of this, there has been proposed a paper sheet identification device that reads various characteristics of a true bill and compares the read data with a used paper sheet to determine whether it is a fake bill or a true bill (see, for example, Patent Document 1). .

  Further, since a delicate watermark is applied to the true bill to prevent forgery, an apparatus for determining the presence or absence of this watermark has been proposed (see, for example, Patent Documents 2 to 5).

  By the way, a paper sheet identification device that reads various features of a genuine bill as in Patent Document 1 and compares the read data with a used paper sheet to determine whether it is a fake bill or a genuine bill is included in a cash throwing machine. Although suitable, the device is complex and has the disadvantage that it is too large for use by store cashiers and taxi drivers.

  Moreover, although the apparatus which determines the presence or absence of the watermark currently disclosed by patent documents 2-5 is the point which is the tray type which attached the illuminating device, it is obvious that it is judging by shining light from the bottom. So, the problem remains that there is psychological resistance to use for most good customers.

  The present invention provides a paper sheet discriminator capable of solving such a conventional difficulty, having a simple structure, compact, and giving a natural impression that a bill received for change confirmation is placed nearby. It is an object.

  The paper sheet discriminator according to the first aspect of the present invention is configured by a translucent member and determines whether the paper sheet has a watermark for preventing counterfeiting in the watermark portion, and the cross section is vertically upward. It is formed by a pair of standing V-shaped or U-shaped standing plates, and a sheet of paper is inserted between the standing plates and placed on the base where the standing plates are joined. The watermark portion is irradiated from at least one of the standing plates that are projected and illuminated, and the presence or absence of the watermark is determined by transmitting light.

  The paper sheet discriminator according to the second aspect of the present invention is made of a translucent member and determines whether or not the paper sheet has a forgery-preventing watermark in the watermark portion, and the cross section is vertically upward. It is formed by a pair of standing V-shaped or U-shaped standing plates, and a sheet of paper is inserted between the standing plates and placed on the base where the standing plates are joined. Irradiate the watermark from at least one of the standing plates that are illuminated and illuminate, and determine whether or not there is a watermark by transmitting the light. And a light source unit that illuminates the standing plate.

  In the paper sheet discriminator according to the third aspect of the present invention, the pair of standing plates and the base portion are integrally formed.

  In the paper sheet discriminator according to the fourth aspect of the present invention, the translucent member is an acrylic resin.

  According to the first to fourth aspects of the paper sheet discriminator of the present invention, the structure is simple and compact, and it is suitable for use by a cashier of a store, a taxi driver or the like.

  In addition, a natural impression can be given to the customer that the banknotes received for change confirmation have been placed nearby.

  A preferred embodiment of a paper sheet discriminator according to the present invention will be described below in detail with reference to the drawings.

  In determining whether the paper sheet 1 has the watermark 20 for preventing forgery in the watermark portion 2, the paper sheet discriminator according to the present invention is composed of a translucent member as shown in FIG. A base whose cross section is formed by a pair of upright plates 31 and 32 having a V-shape opened upward in the vertical direction, and a sheet of paper is inserted between the upright plates 31 and 32 and the upright plates 31 and 32 are joined together. By irradiating the watermark portion 2 from at least one of the standing plates 31 and 32 that are placed on the portion 41 (4) and projected from the cross-sections of the standing plates 31 and 32, the light is transmitted. A paper sheet holding part 51 (5) for determining the presence or absence of the watermark 20 and a light source part 6 for projecting light on the cross section of the standing plates 31 and 32 to illuminate the standing plates 31 and 32 are provided.

  As shown in FIG. 1B, the pair of upright plates 31 and 32 are also suitably formed in a U shape whose cross section is open upward in the vertical direction. As shown in FIG. 2B, when the U-shaped section has open end portions 310 and 320 that are opened upward in the vertical direction, the paper sheet 1 can be easily inserted and removed. It goes without saying that the bottom of the U-shape is suitable even if it is substantially concave.

  As shown in FIG. 3 (a), the area of the standing plates 31, 32 and the area of the paper sheet 1 is such that the area of the standing plates 31, 32 is at least as shown in FIG. The area including the watermark 20 is preferably narrower than the paper sheet 1, and the area of the standing plates 31 and 32 is substantially the same as the paper sheet 1, or the area of the standing plates 31 and 32 is substantially larger than that of the paper sheet 1. If it is large, it is desirable to provide a notch 50 so as to pinch the paper sheet 1 as shown in FIG.

  Furthermore, although the standing plates 31 and 32 are V-shaped or U-shaped so that the cross section is opened upward in the vertical direction, the standing plates 31 and 32 are formed as shown in FIGS. The bottom surface 40 of the member constituting the base portion 4 to be joined is cut in the horizontal direction.

  The pair of upright plates 31 and 32 and the base portion 4 are preferably integrally formed of acrylic resin as a translucent member, but from the bottom surface 40 which is one of the cross sections of the upright plates 31 and 32. It is also suitable if the upright plates 31 and 32 and the base portion 41 (4) are assembled by separate members made of a translucent member so that the upright plates 31 and 32 are illuminated and illuminated. As the translucent member, vinyl chloride (PVC), polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), quartz, or the like may be employed in addition to the acrylic resin.

  Further, the light source unit 6 that illuminates the standing plates 31 and 32 is in contact with the bottom surface 40 cut in the horizontal direction as described above.

  The light source unit 6 may be composed of a very small light bulb and a battery, or may be stored in an optical fiber lamp facing the bottom surface 40 and connected to an external power source, and is turned on at the time of use. A switch (not shown) is provided.

  In the above-described embodiment, the light source unit 6 for illuminating the standing plates 31 and 32 is provided. However, the light source unit 6 can be projected from the bottom to the bottom surface 40 as shown in FIG. It is possible to install the paper sheet holding unit 5 on a flat surface 60 having a light-transmitting property and to illuminate the standing plates 31 and 32, or to project on the side section 30 of the standing plates 31 and 32 Even so, it is possible to determine whether or not there is a watermark by illuminating the standing plates 31 and 32, irradiating the watermark portion, and transmitting light. At this time, the paper sheet holding unit 5 can be attached by a known method such as attaching an L-shaped fixture 7 or the like in the vicinity of the ends of the standing plates 31 and 32 and stabilizing the flat surface 60. This is also suitable for using existing lighting as a light source in a driver's seat of a car, for example.

  The operation of the paper sheet discriminator according to the present invention will be specifically described below.

  A paper sheet discriminator according to the present invention is fixed to one corner of a store cash register that accepts banknotes and changes in a daily manner. For fixing the paper sheet discriminator, a plastic sucker, a magnet, or the like is attached to one of the standing plates 31 and 32 or one surface of the light source unit 6 and fixed to a cash register or a desk. Alternatively, the light source unit 6 may be housed and only the standing plates 31 and 32 may be placed at the top.

  The switch of the light source unit 6 is kept on.

  The received banknote 1 is placed on the base 42 from between the standing plates 31 and 32 (FIG. 1C). The paper sheet 1 may be inserted from the side.

  If the watermark 20 can be clearly recognized near the center of the standing plate 31, it can be determined that the bill has the watermark 20. When the watermark 20 is not recognized in the watermark portion 2, it can be determined as a fake bill.

  This determination operation is the same as the operation that both the customer and the store side temporarily store the bill received by the store side in order to confirm the amount of the bill until the change is handed over. You do n’t feel like you ’re making a decision.

  In FIGS. 1, 2, and 3, the light for illuminating the standing plates 31 and 32 is provided from the bottom surface 40, but is not limited to this position, and is projected from the side cross section 30 of the standing plates 31 and 32. Similarly, it is possible to determine whether or not there is a watermark by illuminating the standing plates 31 and 32, irradiating the watermark portion, and transmitting the light.

  The paper sheet has been described by way of an example of a banknote, but is not limited to a banknote, but is effective in determining the authenticity of other securities, bonds or similar securities that can determine the presence or absence of a watermark.

  In other words, the paper sheet discriminator according to the present invention can quickly and accurately discriminate a paper sheet in an environment where it is required to manually determine authenticity, without causing discomfort to the paper sheet provider. It has the advantage that it can be offered very cheaply.
