Description

The present invention relates to an ETC (Electronic Toll Collection: automatic toll collection system) in-vehicle device, and more particularly to an ETC in-vehicle device in which an ETC IC (Integrated Circuit) card used for toll payment is detachably inserted.

In a conventional ETC on-vehicle device, when a user inserts an IC card into the IC card insertion slot of the ETC on-vehicle device, the contact portion (substrate-side contact terminal) of the ETC on-vehicle device and the contact portion of the IC card (regardless of the state of the vehicle) The card-side contact portion) is constantly maintained in a state where a constant contact pressure is applied (see, for example, Patent Document 1).
JP2005-183074

The conventional ETC on-board unit is always kept in a state where a constant contact pressure is applied to the contact part (board side contact terminal) of the ETC on-board unit and the contact part (card side contact part) of the IC card. Therefore, when parked for a long time under the hot summer sun, etc., the IC card itself is exposed to the environment where the passenger compartment temperature temporarily exceeds the heat resistance temperature of the IC card, and the contact pressure applied to the contact portion Due to thermal deformation, the normal contact pressure cannot be maintained, and as a result, the electrical continuity becomes unstable and the IC card cannot be normally accessed. As for the mounting environment of ETC in-vehicle devices in vehicles, it has been common to install them in areas where direct sunlight is relatively difficult to hit, such as under the dashboard or inside the console box. It is also assumed that an in-vehicle device is mounted. In this case, the temperature environment that direct sunlight exerts on the IC card is more severe.

In addition, many ETC users get off the vehicle with the IC card inserted in the ETC on-board device, and there are many usage forms in which the IC card is always inserted, but there are security problems such as theft of the IC card. There are also points.

For this reason, in recent ETC on-board units, when an IC card remains inside the ETC on-board unit when the ACC (Accessory) power of the vehicle is turned off, a voice guidance is given to the user to remove the IC card. There is also. However, many cases have been reported in which if the IC card is removed when the ACC power supply is turned off, the user cannot pass the ETC gate due to forgetting to insert the IC card when the ACC power supply of the vehicle is turned on.

In view of the above, the object of the present invention is to provide a contact part (board side contact terminal) of the ETC on-board unit and a contact part (card side contact part) of the IC card in an inserted state of the IC card when the ACC power is off. It is an object of the present invention to provide an on-board ETC device that prevents deformation of an IC card and prevents electrical conduction failure by removing the contact pressure between the two.

Another object of the present invention is to prevent the IC card from being stolen by physically separating the IC card from the IC card insertion slot in the inserted state of the IC card when the ACC power is off. It is to provide an ETC vehicle-mounted device.

Means for Solving the Problems and Effects of the Invention

The ETC vehicle-mounted device according to claim 1 is an ETC vehicle-mounted device in which an IC card is detachably inserted, and a first position facing the IC card insertion port of the housing and a first position spaced from the IC card insertion port. An IC card holder movably disposed between the IC card holder and a contact portion of the IC card inserted into the IC card holder when the IC card holder is in the first position. A board-side contact terminal; biasing means for biasing the IC card holder to move to the second position; and the IC card holder against the biasing force of the biasing means when the ACC power is turned on. Drive means for moving to the first position. According to the ETC on-board device of claim 1, by providing the IC card holder that moves mechanically in conjunction with the on / off of the ACC power source of the vehicle, when the ETC on-board device is not used (when the ACC power source is off) ) Can prevent deformation of the IC card by removing a contact pressure applied to the card side contact portion by providing a gap between the card side contact portion and the vehicle-mounted device side contact terminal. In addition, when the IC card is inserted when the ACC power is off, the IC card holder is physically separated from the IC card insertion slot for the user to insert or remove the IC card, so that the IC card cannot be inserted or removed. Thus, the theft damage of the IC card can be prevented.

The ETC vehicle-mounted device according to claim 2 is characterized in that, in the ETC vehicle-mounted device according to claim 1, the IC card holder is disposed so as to be swingable about a pivot. According to the ETC vehicle-mounted device according to claim 2, since the IC card holder is swingably arranged around the pivot, the IC card holder between the first position and the second position is arranged. There is an advantage that the movement can be realized by a simple mechanism.

The ETC on-vehicle device according to claim 3 is the ETC on-vehicle device according to claim 2, wherein the IC card holder is slid in the IC card holder in conjunction with the insertion / extraction of the IC card, and the IC card is removed from the IC card holder. A second urging means for urging the slider in a projecting direction, and the second urging means is locked by locking the slider so as to be integrated with the IC card holder when the IC card is inserted. If the IC card is inserted when the ACC power is off, the IC is provided with a claw mechanism for disabling the force and a swing link member having a long hole through which a pin provided in the slider is inserted. If the card holder is swung around the pivot by the urging force of the urging means and moved to the second position, and the IC card is not inserted, the IC card Holder is thus being moved to the first position by the biasing force of said second biasing means. According to the ETC vehicle-mounted device of claim 3, when the ACC power is off, the driving force of the driving means disappears. However, if an IC card is inserted, the IC card holder is moved by the urging force of the urging means. Since it moves to position 2, the theft of the IC card is prevented. On the other hand, if the IC card is not inserted, the IC card holder is moved to the first position by the urging force of the second urging means, so that the inconvenience that the user cannot insert the IC card can be solved. .

The purpose of removing the contact pressure to the card side contact portion when the ACC power supply is turned off is achieved by disposing the IC card holder in a movable manner.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 are cross-sectional views showing state transitions of the ETC vehicle-mounted device 1 according to Embodiment 1 of the present invention. FIG. 4 is a main part plan view showing the IC card holder 30 and the like of the ETC on-vehicle device 1 according to the first embodiment. FIG. 5 is a plan view of the IC card 100.

The ETC vehicle-mounted device 1 according to the first embodiment includes a housing 10 formed of a horizontally long rectangular parallelepiped box, a printed circuit board 20 disposed along a bottom wall in the housing 10, and an IC card insertion slot of the housing 10. 11, an IC card holder 30 that is pivotally supported by a pivot 32 at a position on the opposite side of the IC card 11, a slider 40 that is slidably disposed in the IC card holder 30, and the IC card holder 30. The main part is comprised from the rocking | fluctuation link member 50 arrange | positioned so that rocking | fluctuation is possible on one side.

The housing 10 has an IC card insertion slot 11 formed in the front wall (left wall as viewed in FIG. 1).

The printed circuit board 20 is mounted with a board-side contact terminal 21, a solenoid 22, an electronic circuit component (not shown) that realizes an ETC function, and the like, and is disposed horizontally inside the housing 10. The printed circuit board 20 is mounted with a substrate-side contact terminal 21 connected to an electronic circuit component (not shown) that realizes the ETC function at a middle position on the front surface side. Further, the printed circuit board 20 is mounted with a solenoid 22 which is a driving means of the IC card holder 30 at a rear side position on the front surface side (right side position in FIG. 1).

The substrate side contact terminal 21 is for obtaining electrical continuity with the card side contact portion 101 (see FIG. 5) of the IC card 100 inserted in the IC card holder 30. The plate spring member is formed so as to be in contact with the portion 101. As illustrated in FIG. 5, when the card side contact portion 101 of the IC card 100 includes six contact regions, the board side contact terminal 21 also includes six leaf spring members.

The solenoid 22 is fixed to the printed circuit board 20, and its plunger is coupled to a mounting shaft 35 implanted in the IC card holder 30. For this reason, the solenoid 22 attracts the plunger when energized, and swings the IC card holder 30 counterclockwise about the pivot 32 against the elasticity of the coil spring 34. Further, when the current is not energized, the attractive force of the plunger disappears, and the IC card holder 30 is swung clockwise around the pivot 32 by the elasticity of the coil spring 34.

The IC card holder 30 is disposed such that both ends on the back side are pivotally supported by a pivot 32 so that the front end face opening faces the IC card insertion slot 11 of the housing 10 (first position). 1) and an IC card retracting position (second position) in which the front end surface opening is separated from the IC card insertion slot 11 of the housing 10. The bottom wall of the IC card holder 30 is provided with a play hole (not shown) through which the board-side contact terminal 21 is fitted. At the IC card insertion / extraction position (first position), the suction force of the solenoid 22 or The card-side contact portion 101 of the IC card 100 inserted into the IC card holder 30 comes into pressure contact with the board-side contact terminal 21 of the printed board 20 through a play hole (not shown) due to the tight elasticity of the coil spring 42. ing. The IC card holder 30 includes a slider 40 that slides in conjunction with the insertion / extraction state of the IC card 100, and a coil spring 42 that urges the slider 40 to move forward.

As shown in FIG. 4, the slider 40 is disposed in the IC card holder 30 so as to be slidable in the front-rear direction (left-right direction as viewed in FIG. 4), and on the rear side (right side as viewed in FIG. 4). A pin 41 is planted on one side. The pin 41 is loosely fitted into a long hole 30a (see FIG. 1) formed in one side surface of the IC card holder 30 and a long hole 50a (see FIG. 1) of the swing link member 50, and further extends. The other end of the coil spring 42 having one end engaged with a pin 35 planted on one side of the front side (left side as viewed in FIG. 4) of the IC card holder 30 is engaged with the tip end side. .

The swing link member 50 is a belt-like plate body with a long hole 50a formed along the longitudinal direction, and is pivotally supported by a pivot 51 fixed to the housing 10 at the lower end portion so as to be swingable. . A pin 41 implanted in the slider 40 is loosely fitted in the long hole 50a. For this reason, the swing link member 50 swings about the pivot 51 with the slide of the slider 40 by the insertion of the IC card 100 by the user and the swing of the IC card holder 30. The role of the swing link member 50 is to convert the elastic tension of the coil spring 42 into the rotational force of the IC card holder 30. In the case where the IC card 100 is incompletely inserted (the slider 40 is not on the left end side in FIG. 4), it is necessary to create a state in which the card can be surely inserted. The rotational force to be pulled into (first position) is generated by the coil spring 42 and the swing link member 50. That is, in a state in which the IC card 100 is not inserted, the contraction elastic force of the coil spring 42 is superior to the elastic force of the coil spring 34, so that the IC card holder 30 swings counterclockwise about the pivot 32 via the swing link member 50, The IC card naturally returns to the IC card insertion / extraction position (first position). The swing link member 50 also has a function of generating a certain tension and fixing the position so that the IC card holder 30 is not detached from the substrate side contact terminal 21 more than necessary when the IC card 100 is inserted. To do.

Next, the operation of the ETC vehicle-mounted device 1 according to the first embodiment configured as described above will be described with reference to FIGS. 1 to 5.

(1) The IC card 100 is not inserted when the ACC power is off.

When the IC card 100 is not inserted when the ACC power is turned off, the suction force of the solenoid 22 is not generated, and the IC card holder 30 has the pin 41, the slider 40, and the swing link member 50 by the elastic force of the coil spring 42. 1 to receive a rotational force that oscillates counterclockwise about the pivot 32 against the elasticity of the coil spring 34, and has a horizontal IC card insertion / extraction position (first position) as shown in FIG. I keep it. For this reason, the user can arbitrarily insert and remove the IC card 100 from the ETC in-vehicle device 1.

(2) Inserting the IC card 100 when the ACC power is off

When the IC card 100 is not inserted when the ACC power is off and the user inserts the IC card 100 into the ETC in-vehicle device 1 from the IC card insertion slot 11 as shown by a broken line in FIG. Are inserted into the IC card holder 30 while sliding the slider 40 against the contraction elasticity of the coil spring 42. As the slider 40 slides, the pin 41 implanted in the slider 40 moves, so that the swing link member 50 swings clockwise about the pivot 51 through the pin 41 and the long hole 50a.

As shown in FIG. 2, when the IC card 100 is completely inserted into the ETC on-vehicle device 1, the slider 40 is locked integrally with the IC card holder 30 by a claw mechanism (not shown). For this reason, the elastic force of the coil spring 42 does not act on the pin 41, and the IC card holder 30 is separated from the printed circuit board 20 around the pivot 32 by the elasticity of the coil spring 34 as shown in FIG. Swing to (second position) and stop. As a result, a gap is generated between the card side contact portion 101 of the IC card 100 and the board side contact terminal 21 of the printed circuit board 20, and the contact pressure with respect to the card side contact portion 101 is removed. For this reason, deformation of the IC card 100 is prevented, and the IC card holder 30 swings to a position where the IC card 100 cannot be structurally removed from the IC card insertion slot 11, so that removal of the IC card 100 is prevented. Is done. As the IC card holder 30 swings, the pin 41 implanted in the slider 40 moves, so that the swing link member 50 swings further clockwise around the pivot 51 through the pin 41 and the long hole 50a. To do.

(3) When the IC card 100 is inserted, the ACC power is turned off to on.

When the ACC power supply is turned on in the inserted state of the IC card 100 shown in FIG. 3, the driving power is supplied to the solenoid 22, and the IC card holder 30 is made elastic by the coil spring 34 by the suction force of the solenoid 22. On the contrary, it swings counterclockwise around the pivot 32 and moves in a direction close to the printed circuit board 20. As shown in FIG. 2, the IC card holder 30 swings to a horizontal card insertion / removal position (first position) where the front end face opening faces the IC card insertion slot 11 of the housing 10 and stops. At this time, the swing link member 50 swings slightly counterclockwise about the pivot 51 through the pin 41 and the long hole 50a.

In FIG. 2, the IC card 100 has a board-side contact terminal through a play hole (not shown) formed in the bottom wall of the IC card holder 30 by the suction force of the solenoid 22. 21. For this reason, the card side contact portion 101 of the IC card 100 and the substrate side contact terminal 21 are brought into electrical contact with each other with a predetermined contact pressure. Therefore, the ETC onboard equipment 1 becomes operable.

When an unillustrated eject button is operated at the card insertion / removal position (first position) of the IC card holder 30, the lock for integrating the slider 40 and the IC card holder 30 by the claw mechanism described above is released, and the coil spring 42 The austerity resilience is restored. For this reason, the slider 40 is slid to the near side (left side as viewed in FIG. 2) by the elastic force of the coil spring 42, and the IC card 100 protrudes forward from the IC card holder 30 as shown in FIG. become. For this reason, the user can extract the IC card 100 from the ETC vehicle-mounted device 1. At this time, the swing link member 50 swings counterclockwise about the pivot 51 via the pin 41 and the long hole 50a in conjunction with the slide of the slider 40.

(4) When the IC card 100 is inserted, the ACC power is turned on to off.

When the ACC power supply is turned off from the on state in the inserted state of the IC card 100 shown in FIG. 2, the suction force of the solenoid 22 disappears, so that the IC card holder 30 is moved by the elasticity of the coil spring 34 as shown in FIG. Then, it swings clockwise around the pivot 32 and moves to a card retracting position (second position) that is separated from the printed circuit board 20. As a result, a gap is generated between the card side contact portion 101 of the IC card 100 and the board side contact terminal 21 of the printed circuit board 20, and the contact pressure with respect to the card side contact portion 101 is removed. For this reason, deformation of the IC card 100 is prevented, and the IC card holder 30 swings to a position where the IC card 100 cannot be structurally removed from the IC card insertion slot 11, so that removal of the IC card 100 is prevented. Is done. As the IC card holder 30 swings, the pin 41 implanted in the slider 40 moves, so that the swing link member 50 swings clockwise about the pivot 51 through the pin 41 and the long hole 50a. .

According to the first embodiment, by providing the IC card holder 30 that swings mechanically in conjunction with the on / off of the ACC power supply of the vehicle, when the ETC on-vehicle device 1 is not used (when the ACC power supply is off). The contact pressure applied to the card side contact portion 101 can be removed by providing a gap between the card side contact portion 101 and the ETC on-vehicle device side contact terminal 21, thereby preventing the deformation of the IC card 100. it can.

Further, according to the first embodiment, when the ETC on-vehicle device 1 is not used (when the ACC power is off), the suction force of the solenoid 22 disappears, but if the IC card 100 is inserted, the IC card holder Since 30 is moved to the card retracting position (second position) by the elasticity of the coil spring 34, the IC card 100 is prevented from being stolen. On the other hand, if the IC card 100 is not inserted, the IC card holder 30 is moved to the card insertion / removal position (first position) by the elastic force of the coil spring 42, thereby eliminating the inconvenience that the user cannot use the IC card 100. Can do.

In the first embodiment, the IC card holder 30 is disposed so as to be swingable about the pivot 32. However, any mechanism may be used for moving the IC card holder. For example, it goes without saying that the IC card holder 30 may be a mechanism that horizontally moves or vertically moves.
