Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card insertion detection mechanism, and more particularly, to a prepaid card insertion detection mechanism for facilitating front / back and front / back identification of a card to detect erroneous insertion into a reader / writer.

[0002]

[Prior art]

 Recently, prepaid cards have become popular. Such a card-type medium requires filling and updating of recorded contents, and is generally inserted into a reader / writer to perform an update regardless of whether it is a print card, a magnetic card, or an optical card. Is. By the way, card-type media are similar in terms of structure and shape, and the front and rear sides of the card are also similar. Therefore, in order to prevent erroneous insertion into the reader / writer, for example, a method of printing a mark such as an arrow indicating the front direction on the front side is widely adopted.

[0003]

[Problems to be solved by the device]

 However, in most of the cards having the above-described conventional configurations, the printed insertion direction instruction mark is difficult to see, and most of the cards are extremely unusable. In addition, the reader / writer device must be capable of handling any erroneous insertion and equipped with a function to quickly determine the insertion status, but the conventional prepaid card insertion detection mechanism has a configuration that meets such requirements. Did not exist.

The present invention has been made to solve the problems of the prior art, and the purpose thereof is to easily confirm the direction of the inserted card and to quickly determine the inserted state. It is to provide a prepaid card insertion detecting mechanism.

[0005]

Means for Solving the Problems A prepaid card insertion detection mechanism according to the present invention is a first prepaid card having a pair of long sides and a pair of short sides. A circular first through hole is provided in a corner at a position separated from a long side of one card by a predetermined distance, and a corner diagonal to the first corner is defined as a second corner, and a second corner is defined as the other corner. A direction detecting through hole having a configuration in which a triangular second through hole is provided at a position separated from the long side of the card by the distance, and the diameter of the first through hole is larger than the diameter of the inscribed circle of the second through hole. Of the prepaid card insertion detection mechanism, in which two hall elements are provided at a position closer to the center side from both ends of the short side of the prepaid card to be inserted, respectively, by overlapping. Pre-paid with sensors Two pressing devices are provided to face the two position sensors with the card sandwiched between them, and each pressing device is urged by a spring at all times to be movable, and is integrally formed with a thin pin and a thick pin. A small diameter pin is provided, the surface of the small diameter pin is coated with a magnetic layer, and both the small diameter pin and the large diameter pin pass through the circular through hole of the prepaid card, and the small diameter pin is moved. The magnetic layer turns on both of the two hall elements stacked, and only the pin having the small diameter passes through the triangular through hole of the prepaid card to move the magnetic property of the pin having the small diameter. It is characterized in that the layer is configured to turn on only the lower stage of the two Hall elements.

[0006]

[Action]

 The prepaid card insertion detection mechanism of the present invention configured as described above is provided with the direction detection through-holes in which the positions and shapes of the through-holes appearing on the short side correspond to the four insertion states of the front side and the back side and the front-rear direction. When the prepaid card with a hole is inserted, the small-diameter pin or the large-diameter pin of the pressing device passes through the through hole that appears on the short side. If the through hole is a triangle, a pin with a diameter smaller than the inscribed circle of this triangle passes through the through hole and penetrates the prepaid card, and the magnetic layer of the thin pin turns on the Hall element in the lower stage. However, a pin with a diameter larger than the inscribed circle of this triangle cannot pass through the through-hole, and therefore, a small-diameter pin integrally configured with the large-diameter pin cannot proceed any further, so that the Hall element in the upper stage is not turned on.

If the through hole has a circular shape, the pin having a diameter smaller than the circular shape passes through the through hole and penetrates the prepaid card, and the magnetic layer of the pin having a small diameter turns on the Hall element in the lower stage. Furthermore, a pin with a large diameter that does not exceed the circular diameter also passes through the through hole. Therefore, the small-diameter pin integrated with the large-diameter pin advances further, and the magnetic layer of the small-diameter pin also turns on the Hall element in the upper stage. That is, if the through hole is triangular, only one Hall element is turned on, and if the through hole is circular, both Hall elements are turned on. This confirms the front / back surface and the front-back direction of the inserted prepaid card.

【Example】

 FIG. 1 is a top view of an embodiment of the prepaid card insertion detection mechanism of the present invention. Further, FIG. 2 is a sectional view of an essential part of the prepaid card insertion detection mechanism of FIG. FIG. 3 is an explanatory view of a through hole provided in the prepaid card inserted in the prepaid card insertion detecting mechanism of the present invention. Further, FIG. 4 is an explanatory view of the operation of the prepaid card insertion detection mechanism of the present invention. Hereinafter, first, the prepaid card to be inserted will be described with reference to FIG.

The prepaid card 1 to be inserted into the prepaid card insertion detection mechanism of the present invention has an arbitrary corner of an arbitrary surface as a first corner, and the first corner is separated from the long side of one card by a distance d 1. A circular first through hole H1 is provided at a position, and a corner diagonal to the first corner is defined as a second corner, and a second corner is formed at a position separated by a distance d from the other long side of the card. The second through hole H2 is provided, and the diameter of the circular first through hole H1 is larger than the diameter of the inscribed circle of the triangular second through hole H2.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The prepaid card insertion detection mechanism 10 of the present invention includes position sensors S1 and S2 each having two Hall elements 5 and 6 stacked at a position closer to the center by a distance d from both ends of the short side of the inserted prepaid card 1. Arrange. Further, pressing devices P1 and P2 are provided so as to face the position sensors S1 and S2 with the prepaid card 1 in between. Each of the pressing devices P1 and P2 includes a small-diameter pin 11 and a large-diameter pin 12 that are integrally biased by a spring 13 and are movable so as to be movable. The surface of the pin 11 having a small diameter is coated with a magnetic layer 15. The large-diameter pin 12 passes through the circular through hole H1 of the prepaid card 1. At this time, the pin 11 having a small diameter moves largely upward, and the magnetic layer 15 turns on both of the two Hall elements 5 and 6 which are stacked. On the other hand, the thick pin 12 does not pass through the triangular through hole H2 of the prepaid card 1. Therefore, only the small-diameter pin 11 passes through the triangular through hole H2, and the magnetic layer 15 turns on only the lower Hall element 6 of the two Hall elements 5 and 6 that are stacked. ing.

As described above, the large diameter pin 12 passes only through the circular through hole H1 of the prepaid card 1, and the small diameter pin 11 passes through both the circular through hole H1 and the triangular through hole H2. It is configured to pass. In such a configuration, for example, the diameter of the thin pin 11 is set smaller than the inscribed circle of the triangular through hole H2, and the diameter of the large pin 12 is set smaller than the inscribed circle of the triangular through hole H2. Is also large and is realized by setting the diameter of the circular through hole H1 so as not to exceed the diameter.

With the above configuration, the front / back / front and back of the card can be easily discriminated. For example, when the prepaid card 1 is inserted into the reader / writer with the front edge 1C as the tip, if the front surface 1A is projected upward, the card tip 1C has a circular first portion at a distance d from the upper edge 1E. The through hole H1 appears. The small-diameter pin 11 of the pressing device P2 first passes through the first through hole H1, and the magnetic layer 15 at the tip of the pin 11 turns on the Hall element 6 in the lower stage of the position sensor S2, and further through the first through hole H1. When the large-diameter pin 12 passes, the pin 11 further advances (upward in the drawing), and the magnetic layer 15 of the pin 11 turns on the Hall element 5 in the upper stage of the position sensor S2. By turning on both the hall elements 5 and 6 of the position sensor S2, it is detected that the through hole H1 is at the position of the position sensor S2.

If the card is turned upside down and the surface 1B is exposed to the upper side, the first through hole H1 appears on the lower side as shown in the figure. The pin 11 and the pin 12 of the pressing device P1 pass through the first through hole H1, and the magnetic layer 15 turns on the lower Hall element 6 and the upper Hall element 5 of the position sensor S1. By turning on both the hall elements 5 and 6 of the position sensor S1, it is detected that the through hole H1 is at the position of the position sensor S1.

Next, when the front side 1A is exposed to the upper side when the rear side 1D is inserted into the reader / writer with the front side being the front side, a triangular second through hole H2 appears on the upper side in the card front side 1D. . The small-diameter pin 11 of the pressing device P2 passes through the second through hole H2, and the magnetic layer 15 at the tip of the pin 11 turns on the Hall element 6 in the lower stage of the position sensor S2. However, since the large-diameter pin 12 cannot pass through the second through hole H2, the pin 11 cannot move any further (upward in the figure), so that the hall element 5 in the upper stage of the position sensor S2 cannot move. Not turned on. By turning on only the lower Hall element 6 of the position sensor S2, it is detected that the through hole H2 is located at the position of the position sensor S2.

If the card is turned upside down and the surface 1B is exposed to the upper side, the second through hole H2 appears on the lower side as shown in the figure. The small-diameter pin 11 of the pressing device P1 passes through the second through hole H2, and the magnetic layer 15 at the tip of the pin 11 turns on the Hall element 6 at the lower stage of the position sensor S1. However, since the large-diameter pin 12 cannot pass through the second through hole H2, the pin 11 cannot move any further (upward in the drawing), so that the Hall element 5 in the upper stage of the position sensor S1 is not turned on. . By turning on only the lower hole element 6 of the position sensor S1, it is detected that the through hole H2 is at the position of the position sensor S1.

As described above, the first to second position sensors detect each of the four cases of different front / back / front and back of the card based on the ON state of the two Hall elements included in each. As a result, it is possible to very easily distinguish between different front / back / front and rear insertion states of the card. Moreover, since the detection can be performed only by inserting the tip of the card slightly, it is not necessary to take all the cards into the device, and the time can be shortened.

[0017]

[Effect of device]

 As described above, the prepaid card insertion detection mechanism of the present invention detects through-holes of different positions and shapes that appear on the short side corresponding to four insertion states that are different in the front and back directions and the front-back direction. Therefore, it becomes possible to easily detect the front / back surface and the front / back direction of the inserted prepaid card. Therefore, there is an effect that the user's erroneous insertion detection can be executed in an extremely short time after inserting the card.
