no. 1 Embodiment approach

[0024] figure 1 It is a system configuration diagram of the paper sheet discriminating device of the first embodiment. figure 1 The illustrated paper identification device 1 is embedded in a paper processing device such as an ATM (Automated Teller Machine) and used to judge the denomination and authenticity of paper bills inserted into the ATM or the like.

[0025] Such as figure 1 As shown, the sheet identification device 1 has an input unit 2 , an image sensor 3 , a conversion unit 4 , a reference data storage unit 5 , and a determination unit 6 .

[0026] The input unit 2 accepts banknotes inserted into the ATM. The image sensor 3 reads image data of banknotes inserted into the input unit 2 . In the sheet discriminating device 1 of the present embodiment, a line sensor using a transmissive photoelectric sensor is used as the image sensor 3 .

[0027] The conversion unit 4 converts the image data read by the image sensor 3 . Regarding the conversion method of image d...

no. 2 Embodiment approach

[0043] The paper sheet discriminating apparatus 1 of the above-mentioned embodiment acquires data for four directions by changing the reading direction of the image data 20 obtained from the inputted banknote, and compares it with the template 30 . In contrast, the paper sheet identification device of this embodiment is different in that, for the template 30 having a certain direction, the direction of reading is changed to obtain data for four directions, which is different from the input banknotes. The resulting image data are compared.

[0044] Next, a method of discriminating banknotes in the paper discriminating device of this embodiment will be specifically described.

[0045] image 3 It is a system configuration diagram of the paper sheet discriminating device of this embodiment. exist image 3 In the shown paper sheet identification device 11, for figure 1 The same structure as the above-mentioned embodiment shown, marked with figure 1 The same reference numera...

no. 3 Embodiment approach

[0056] The paper sheet discriminating device of this embodiment is similar to the paper sheet discriminating device 11 of the above-mentioned second embodiment, generates converted data of a template, performs pattern matching using the converted data, and discriminates banknotes.

[0057] However, the sheet discriminating device of the above-mentioned second embodiment uses a line sensor using a transmissive photoelectric sensor as the image sensor 3 . On the other hand, the sheet discriminating device of this embodiment is different in that a line sensor using a reflective photoelectric sensor is used as an image sensor.

[0058] Next, a method of discriminating banknotes in the paper discriminating device of this embodiment will be specifically described.

[0059] In addition, the structure of the paper sheet identification device of this embodiment is the same as image 3 Similarly, as described above, the difference from the sheet discriminating device 11 of the second e...

Abstract

The invention provides an identification device for paper sheets and an identification method therefore. According to the identification device, the storage capacity of a storage template can be suppressed. The identification device (1) for paper sheets comprises a reference data storage part (5) for storing reference templates (30) used for discriminating paper money. An image sensor (3) acquires the image data (20) of the imputed paper money. With the data of the templates (30) or the acquired image data (20) as the object, a conversion part (4) reads out the direction of the pre-set different directions of the data and generates the conversion data. A determination section (6) identifies the inputted paper money by using the conversion data.

Description

technical field [0001] The present invention relates to a technique for discriminating sheets by comparing input sheets with a template. Background technique [0002] In a conventional paper sheet (banknote) processing device for financial institutions, reference data of currency types to be discriminated is stored as a template in a storage unit of the device. Whenever a paper sheet is put in, the paper sheet processing device reads the paper sheet optically, obtains image data such as grayscale values, detects the pattern and shade of the paper sheet put in based on the obtained image data, and Pattern matching is carried out between the template and the detection result, thereby judging the type (currency) and authenticity of the input paper sheets. [0003] In the past, such as Figure 6 As shown, templates for four directions, ie, front and back, and up and down directions, are usually installed for a kind of paper, so that no matter which direction the paper is put in...
