平行に設けてなる。As shown in the figure, the magnetic card l of this embodiment has a strip-shaped magnetic recording area 2 for magnetically recording data along the longitudinal direction of the magnetic card 1, and a strip-shaped magnetic recording area 2 with punched holes for marking the number of uses, etc. A punch hole portion 3 is provided in parallel to the magnetic recording area 2.

となる。The punched hole portion 3 is divided into a plurality of small sections 31 along the longitudinal direction. This small section 31 is provided corresponding to the punching position of the punch hole 5, and therefore, the punch hole 5 is made in the small section 31 as shown in the figure.

別できることとなる。The surface of the small section 31 is coated with two types of ink having the same reflectance in the visible light range and different reflectance in the infrared rays. As a result, although the subdivisions 31 cannot be visually identified under normal conditions, they can be identified as two types of divisions by irradiating the punched holes 3 with infrared rays and comparing the reflectances.

を備えて構成されている。The punch hole detection device M4 includes an LED 41 as a light source that irradiates the punch hole portion 3 of the magnetic car 1''1 with infrared rays;
A light receiving sensor 42 as a light receiving part that receives infrared rays reflected by the punched hole part 3; a reflectance detection part 43 that detects the infrared reflectance of the punched part 3 from the light reception signal of the light receiving sensor 42; The apparatus includes a comparison section 44 that compares the detection signal of the section 43 with a predetermined normal signal pattern, and a pattern storage section 45 that stores the normal signal pattern.

)。Next, the operation of detecting the punched hole 5 by the punched hole detection device 4 and its effect will be explained. Note that, as shown in FIGS. 3(a), 3(b), and 3(c), the punched hole portion 3 is coated with ink having a different infrared reflectance for each subdivision 31 (in the figure, diagonal lines indicate (Indicates that the area is subsection 31 coated with ink with high infrared reflectance).

信号は欠落する。First, when the magnetic card 1 is inserted into the punch hole detection device 4, the LED 41 emits infrared rays and irradiates the punch hole portion 3 with the infrared rays. The light receiving sensor 42 receives the infrared rays reflected by the punched hole portion 3, and sends a light receiving signal to the reflectance detecting section 43. The 0 reflectance detecting section 43 calculates the reflectance of the infrared rays from the light receiving signal and calculates the reflectance as shown in the figure. It outputs an output signal whose size corresponds to the reflectance. At the punch hole 5, there is no reflection of the infrared rays, and the signal is lost as shown in FIG. 3(b).
この検出信号と、パターン記憶部45に予め格納した正
常な信号パターンとを比較部44が比較し、比較結果よ

なる。The comparison section 44 compares this detection signal with a normal signal pattern previously stored in the pattern storage section 45, and it is detected from the comparison result whether the punched hole 5 is normal or not.

さくなる。If the magnetic card 1 is counterfeited, even if the punch holes 5 are covered with the same material as the magnetic card 1, for example, the chips produced when punching the punch holes 5, the small section 31 where each punch hole 5 is located will be covered. If chips coated with the same ink are not used, a normal signal pattern cannot be restored due to the difference in infrared reflectance, and a counterfeit magnetic card will be determined. When the holes 5 are closed, the probability that the ink applied to the small section 31 and the chips in each punch hole 5 match is equal to 1, so the probability that a normal signal pattern can be restored is n, which is extremely small.
第3図(C)に、第3図(b)のパンチ孔5のうち左か

区分と異なるインクを塗布した切屑で塞いだ例を示す。FIG. 3(C) shows an example in which the first and second punch holes 5a and 5b from the left among the punch holes 5 in FIG. 3(b) are closed with chips coated with inks different from the subdivisions, respectively. show.

きる。As shown in the figure, the detection signal indicates that the reflectance at the position of the punched hole 5a is significantly lower than that of the surrounding subsection 31, and that the reflectance at the position of the punched hole 5b is significantly higher than that of the surrounding subsection 31. It shows. By comparing this detection signal with a normal signal pattern in the ratio s2 section 44, it can be detected that the punch holes 5a and 5b are blocked by foreign matter.
上述したパンチ孔検出装M4は、磁気カードlの読取装
置に組込んで用いてもよく、単独で使用してもよい。The punch hole detection device M4 described above may be used by being incorporated into a reading device for a magnetic card I, or may be used alone.

度に熱して差異を検出してもよい。In this example, inks with different infrared reflectances were applied to the subdivisions 31 of the punched hole portion 3, and differences in infrared reflectance were detected. However, two types of inks with different optical characteristics were used. Other means may also be used. For example, one of the inks applied to the small section 31 may be an ultraviolet emitting ink (fluorescent ink, etc.) and the punched hole part 3 may be irradiated with ultraviolet light to detect the presence or absence of light emission, or two types of ink may be applied to the small section 31 to form metamerism. Alternatively, a color filter may be used to detect the difference. Alternatively, one of the inks applied to the subdivisions 31 may be a thermosensitive coloring ink, and the punched holes may be heated to a predetermined temperature to detect the difference.

果がある。[Effects of the Invention] As explained above, the present invention divides the punch hole provided in the magnetic card into subdivisions including the punch hole positions,
Since the small sections are painted with inks with different optical properties, even if the punch holes are plugged with the same material as the magnetic cart, the punch holes can be detected and the punch holes are blocked by inspecting the optical characteristics of the small sections. This has the effect of making it possible to detect whether the magnetic card has been stolen and preventing counterfeiting or tampering with the magnetic card.
