[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 electromagnetic solenoids are provided at the center side from the both ends of the short side of the inserted prepaid card by the distance described above. Install the sensor and Two pressing devices are provided facing the two position sensors with a card inserted between them, and each pressing device is urged by a spring at all times to be movable, and is integrally configured with a small-diameter magnetizing pin and a thick magnetizing body pin. Both the small-diameter magnetizing body pin and the large-diameter magnetizing pin pass through the circular through hole of the prepaid card, and the moved thin-diameter magnetizing body pins are used to stack the two electromagnetic solenoids. Only the small-diameter magnetic attraction pin passes through the triangular through hole of the prepaid card, and the moved small-diameter magnetic attraction pin is inserted only in the lower stage of the two electromagnetic solenoids. It is characterized by being configured.

[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 a prepaid card with a hole is inserted, the small-diameter magnetizing pin or the large-diameter pin of the presser passes through the through hole that appears on the short side. If the through hole is triangular, the magnet pin with a diameter smaller than the inscribed circle of the triangle passes through the through hole and penetrates the prepaid card, and the induction current due to the insertion of the magnet pin with a small diameter causes the lower electromagnetic solenoid. However, a pin with a diameter larger than the inscribed circle of this triangle cannot pass through the through-hole, so a small-diameter magnetizing pin integrated with the large-diameter pin cannot proceed any further, and therefore the upper electromagnetic No induced current is generated in the solenoid.

If the through hole has a circular shape, the magnetic attraction pin having a diameter smaller than the circular shape passes through the through hole and penetrates the prepaid card, and an induction current due to the insertion of the small diameter magnetic attraction pin is applied to the lower electromagnetic solenoid. appear. Furthermore, a pin with a large diameter that does not exceed the circular diameter also passes through the through hole. Therefore, the small-diameter magnet body pin integrated with the large-diameter pin further progresses, and an induced current due to the insertion of the small-diameter magnet body pin is also generated in the upper electromagnetic solenoid. That is, if the through hole is triangular, the induced current is generated only in one electromagnetic solenoid, and if the through hole is circular, it is generated in both electromagnetic solenoids. As a result, the front / back surface and the front-back direction of the inserted prepaid card are confirmed.

【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, which are provided with two electromagnetic solenoids 5 and 6, respectively, which are superposed on the center side of the inserted prepaid card 1 by a distance d from both ends of the short side. 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 units P1 and P2 is provided with a small-diameter magnetic attraction body pin 11 and a large-diameter pin 12 which are integrally biased by a spring 13 so as to be movable. The large-diameter pin 12 passes through the circular through hole H1 of the prepaid card 1. At this time, the small-diameter magnetic attraction pin 11 moves largely upward, and the small-diameter magnetic attraction pin 11 is inserted into both of the two electromagnetic solenoids 5 and 6 that are stacked, and the two electromagnetic solenoids are inserted. An electric current is generated in both the noids 5 and 6. 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 magnetic attraction pin 11 passes through the triangular through hole H2 and is inserted only in the lower electromagnetic solenoid 6 of the two stacked electromagnetic solenoids 5 and 6. There is.

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 magnetic attraction pin 11 includes either the circular through hole H1 or the triangular through hole H2. It is configured to pass through. With such a configuration, for example, the diameter of the thin magnetic induction body pin 11 is set to be smaller than the inscribed circle of the triangular through hole H2, and the diameter of the large diameter pin 12 is set to the inner diameter of the triangular through hole H2. It is realized by setting it so as not to exceed the diameter of the circular through hole H1 which is larger than a circle.

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 magnetizing body pin 11 of the pressing device P2 first passes through the first through hole H1, and the tip of the small-diameter magnetizing body pin 11 is inserted into the lower electromagnetic solenoid 6 of the position sensor S2 to generate an electric current. When the large-diameter pin 12 further passes through the first through hole H1, the pin 11 advances further (upward in the drawing), and the small-diameter magnetic attraction pin 11 moves to the electromagnetic solenoid 5 on the upper stage of the position sensor S2. Is also inserted, and a current is also generated in the electromagnetic solenoid 5. It is determined that the through hole H1 is at the position of the position sensor S2 by the generation of currents in the electromagnetic solenoids 5 and 6 in 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 presser P1 pass through the first through hole H1, and the small-diameter magnetizing pin 11 is inserted into the lower electromagnetic solenoid 6 and the upper electromagnetic solenoid 5 of the position sensor S1 to generate a current. generate. It is determined that the through hole H1 is at the position of the position sensor S1 by the generation of electric currents in the electromagnetic solenoids 5 and 6 in 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 magnet body pin 11 of the pressing device P2 passes through the second through hole H2, and the small-diameter magnet body pin 11 is inserted into the lower electromagnetic solenoid 6 of the position sensor S2 to generate a current. 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 electromagnetic solenoid 5 on the upper stage of the position sensor S2 is not supplied with current. Does not occur. It is determined that the through hole H2 is at the position of the position sensor S2 by the current generated only by the electromagnetic solenoid 6 on the lower side 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 magnetizing body pin 11 of the pressing device P1 passes through the second through hole H2, and the small-diameter magnetizing body pin 11 is inserted into the electromagnetic solenoid 6 in the lower stage of the position sensor S1 to generate a current. . 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 electromagnetic solenoid 5 in the upper stage of the position sensor S1 is not supplied with current. Does not occur. It is determined that the through hole H2 is located at the position of the position sensor S1 by the electric current generated only by the electromagnetic solenoid 6 in the lower stage of the position sensor S1.

As described above, the first to second position sensors respectively determine four cases in which the front and back sides / front and back sides of the card are different, based on the current generation states of the two electromagnetic solenoids included in each. As a result, different insertion states of the front / back / front and back of the card can be distinguished very easily and surely. Moreover, the detection can be performed only by inserting the tip of the card slightly, so that it is not necessary to take the card 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.
