Description

Integrated sensor module fo Bill counter>

The present invention relates to an integrated sensor module structure for a counter, and more particularly, to an integrated sensor module structure for a counter, and more particularly, The present invention relates to an integrated sensor module structure for a counter which can easily be assembled and which can efficiently use a space of a counter made up of one or two stages.

The bill counter is for counting a gift certificate, a lottery ticket, and a banknote. The conventional bill counter has merely functions for counting bills. Recently, however, a bill counter having a function of discriminating authenticity and denomination of bills has been proposed have.

In general, banknotes are made of special paper containing about 90% cotton fibers to prevent damage during long-term preservation and circulation process due to frequent circulation of paper money. In order to prevent forgery, , Special materials, etc. are inserted into the paper currency paper. In addition, additional methods for preventing forgery are implemented by using special inks or printing methods, such as adding a line to a bill, using an optically variable ink (OVI) in which the color varies depending on the viewing angle , Intaglio Printing which makes convex tactile feel when touching a specific part, Intaglio Latent Image which looks sharp when seen at an angle but does not appear well on copy, (Micro Lettering), which can not be reproduced in the same way, and the use of OVD (Optically Variable Device), which changes shape or color depending on viewing angle.

The counterfeit discrimination is performed by discriminating the presence or absence of the counterfeit preventing means such as the magnetic line, the time varying ink portion, the latent top portion, and the like.

A representative example of the counterfeit identification method is to determine the presence or absence of the fluorescent ink used for printing the banknote. The presence or absence of fluorescence is determined by using a specific visible light ray when ultraviolet light is irradiated on the banknote. That is, when the banknote is printed with the fluorescent ink, the authenticity of the banknote is discriminated by the ultraviolet ray reaction of the banknote sample by using a photosensor which irradiates the banknote with ultraviolet rays and reacts to a specific wavelength band.

However, there is a disadvantage in that it is impossible to discriminate the authenticity of the banknote unless fluorescent ink is used for printing the banknote, and even in the case of using fluorescent ink for banknote printing, disadvantage that the authenticity of the banknote can not be discriminated in the case of using fluorescent inks . On the other hand, even if ultraviolet rays are used for the banknote, the authenticity of the banknote can be discriminated in the above case, but the discrimination of the denomination can not be done in addition to the authenticity discrimination.

Another method of counterfeit discrimination is to discriminate authenticity of a banknote with or without a magnetic line. In this case, when a magnetic line is inserted in a counterfeit or a counterfeit is made using a toner containing a magnetic component, authenticity discrimination There is a drawback that it is difficult.

On the other hand, a bill counter capable of discriminating the denomination of the paper currency is used in addition to the counterfeit discrimination or the counterfeit discrimination function.

As a method for discriminating the denomination of banknotes, there is a method of discriminating authenticity of a banknote and distinguishing denominations by detecting an infrared ink pattern displayed on the banknote by attaching an infrared wavelength light source and a light receiving sensor. However, in this case, there is a problem in that accuracy is poor if the paper feeding direction is changed.

In addition, there is a bill counter that classifies or recognizes a denomination by using a contact image sensor (CIS).

A close-contact type image sensor is a compact image input device in which a light source, a lens, and a sensor portion are integrated, and reads image information by using light. The light source used in the contact type image sensor may be an infrared light source, a visible light source, or an ultraviolet light source as the case may be, and a red, green or blue light source may be used alone.

However, since the contact image sensor generates a two-dimensional image by continuously reading one-dimensional images according to the direction in which the bill advances, when the moving speed of the paper money changes or the left / right movement occurs, There is a problem that distortion occurs. When the moving speed of the paper currency changes, it is difficult to distinguish the paper currency due to the failure to acquire an accurate image.

As a prior art for improving the above problem, Korean Patent Laid-Open Publication No. 2004-90056 (published on October 22, 2004) entitled "Classification of denomination and counterfeit identification counter using CCD sensor" And a feeding roller for feeding the banknote in the rotating blade direction by driving the driving roller and the driving roller for feeding banknotes is provided at the bottom of the hopper. When the banknote is put in the hopper, the driving roller rotates, and the feeding roller connected to the driving roller by the timing belt rotates in accordance with the rotation of the driving roller, thereby conveying the banknote put into the hopper in the rotating blade direction.

The first roller is engaged with the paper feed roller to assist the paper feed operation. The second roller connected to the motor rotates to engage with the third roller so that the transported paper currency can be reliably discharged in the rotating blade direction.

Meanwhile, the driving roller, the feeding roller, the first roller, the second roller, the third roller, the motor, and the like are not limited to the shape or the position as described in the patent publication, Any effective method is irrelevant.

In addition, a CCD sensor and an auxiliary roller for discriminating the type of banknotes to be input are provided, and a counterfeit identification device for identifying whether the banknote to be input is counterfeited is attached to the portion B in Fig. The prior art is equipped with a denomination processor for processing an image acquired from the CCD sensor to identify a denomination.

Prior art CCD sensors may use tens of thousands to millions of pixels, but are not limited thereto. Such a CCD sensor captures an image of a banknote placed on the hopper to be counted and transmits the image to the denomination processor.

The auxiliary roller according to the prior art supports the lower portion of the paper currency during the pre-counting state of the paper currency placed on the hopper and the paper currency, thereby keeping the paper currency plane between the driving roller and the paper feeding roller, thereby preventing the image read by the CCD sensor from being distorted Lt; / RTI >

The counterfeit identification device may be an identification device using ultraviolet rays, an identification device using the presence or absence of a magnetic line, or an identification device using the presence or absence of a portion printed with infrared ink.

As described above, since a CCD sensor, a magnetic sensor, and the like are provided as in the conventional counter or prior art, there is a problem that a space for installing the sensor is separately provided.

In addition, since each of the sensors installed in the counter must be installed, it takes a long time to assemble, and there is also a problem that the labor cost is increased due to an increase in the number of input counter to the production amount of the counter.

In the above prior art, the classification of the denomination can be performed by the CCD sensor. However, in the case of the contaminated paper money, an error occurs in discrimination of the denomination, and in the state where the paper money is withdrawn, Jam (jamming of bills) occurs.
