Abstract

(57) [Abstract] [Purpose] To provide a prepaid card reading device capable of blocking near infrared rays of disturbance and eliminating occurrence of a reading error. A read head 2 for reading near infrared rays is provided, and a shielding portion 3 having a plurality of stepped grooves 3A is arranged in a non-contact manner on at least one surface of an inserted prepaid card 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card reading device, and more particularly to a prepaid card reading device for reading a mark printed on the surface of a prepaid card using near infrared rays.

[0002]

[Prior art]

 Recently, as a prepaid card, mainly for the purpose of data tampering and fraud prevention, the balance is printed and displayed as binary data on the surface of a paper or plastic card with a gray mark, and the display is updated each time the balance is updated. Cards are being used. In addition, for the purpose of maintaining data confidentiality, there is also a method in which the gray mark is printed and displayed with an ink or the like that is sensitive only to near infrared rays. Therefore, a read head using near infrared rays is used for a prepaid card reading device formed of ink or the like that is sensitive to such near infrared rays.

[0003]

[Problems to be solved by the device]

 As described above, the prepaid card that prints and displays the light and shade marks with ink sensitive to near infrared rays has excellent data confidentiality, while the prepaid card reading device using the near infrared reading head For example, there is a configuration in which a light output communication optical diode or the like is present in the surroundings. Therefore, as a result of leaked light entering the read head as a disturbance signal, a read error may occur.

The present invention has been made to solve the above problems and drawbacks of the prior art. Therefore, the purpose of the present invention is to provide a prepaid card reading device capable of blocking the near infrared rays of disturbance to eliminate the occurrence of reading error. To provide.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a prepaid card reading device according to the present invention is provided with a near-infrared reading head, and a shield provided with a plurality of stepped grooves in a non-contact manner on at least one surface of an inserted prepaid card. It is characterized in that it is configured by arranging parts. Alternatively, it is characterized in that it is provided with a read-in head for near infrared rays, and is provided with a shielding portion provided with a plurality of stepped grooves in a non-contact manner on both surfaces of the inserted prepaid card.

[0006]

[Action]

 In the prepaid card reading device according to the present invention, the surfaces of the plurality of stepped grooves provided in the shield part diffusely reflect the near-infrared rays of the incident disturbance, block the incidence, and prevent the incident disturbance. Absorbs near infrared rays. Alternatively, the near-infrared energy of the disturbance is attenuated by diffuse reflection. As a result, the influence of disturbance near infrared rays is eliminated.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings. First, the structure of this invention will be described. FIG. 1 is a side sectional view of a prepaid card reading device according to the present invention. In the figure, a prepaid card reading device 1 according to the present invention includes a pair of shields 3 and 3 having a plurality of stepped grooves 3A inside an outer wall 10 of a reading device having a card insertion slot 11. A read head 2 is provided. The read head 2 includes a near infrared ray emitting section and a reflected light receiving section. The shields 3 and 3 are in non-contact with both the front and back surfaces of the prepaid card 4 in which a plurality of stepped grooves 3A and 3A are inserted from the card insertion slot 11 and are sent to directly below the read head 2 by a feed mechanism (not shown). It is arranged so as to face a very close distance. The stepped grooves 3A, 3A are formed of a material that easily absorbs near infrared rays, for example, a chromium oxide-based material, or a chromium oxide-based plated material.

Next, the operation will be described. When the prepaid card 4 is inserted from the card insertion port 11 and sent to the position just below the read head 2 by a feeding mechanism (not shown), the plurality of stepped grooves 3A, 3A of the shields 3, 3 are attached to the front and back of the prepaid card 4. Place both sides at close range. As a result, the surface of each of the plurality of stepped grooves 3A diffusely reflects the incident near-infrared rays 12 to block the incidence and absorb the incident disturbance near-infrared rays 12. Alternatively, the energy of the disturbance near infrared rays 12 is attenuated by diffuse reflection. As a result, the influence of the near infrared rays 12 of the disturbance on the read head 2 is eliminated.

As described above, the read head 2 can perform accurate access without error not only in reading the data dots 6 but also in reading the position detecting dots 5. Even if the obscuration unit 3 is provided only on the side where the read head 2 is located, the adverse effect of the near-infrared rays 12 of the disturbance on the read head 2 can be almost eliminated. In this case, it is better to provide a cover wall close to the prepaid card 4 on the side without the read head 2. If the occluding portion 3 is provided on both sides of the prepaid card 4, the disturbed near-infrared rays 12 will not further enter the reading head 2.

[0010]

[Effect of device]

 As described above, the prepaid card reading device according to the present invention is provided with the shielding portion having a plurality of stepped grooves that face the surface of the inserted prepaid card in a short distance without contact. Therefore, it is possible to diffusely reflect the incident near-infrared rays, block the incident, absorb the incident near-infrared rays, or attenuate the energy of the disturbance near-infrared rays by diffuse reflection. . Therefore, it is possible to eliminate the incidence of disturbance near infrared rays on the read head, eliminate the occurrence of read error, and enable highly reliable read.
