Description

  For example, the present invention relates to an in-vehicle device used in an ETC system (Electronic Toll Collection system) and an on-vehicle device mounting structure.

  2. Description of the Related Art Conventionally, ETC systems in Japan are based on IC cards (so-called ETCs) that store ETC on-board devices that collect tolls by way of two-way wireless communication with on-road devices installed on the road and information for toll settlement for settlement. Card) (see Patent Document 1).

  The ETC on-board unit and the ETC card are provided separately. The fee settlement information is stolen together with the ETC on-board unit, and the toll fee settlement information is illegally used by others to misuse the stolen fee settlement information. This is to prevent this.

  By the way, with the spread of the ETC system, the ETC in-vehicle device installed in the vehicle is required to be downsized in order to improve the appearance in the attached state. In particular, in order to make the ETC on-board device mountable in a small space and improve the appearance of the mounted state, downsizing and thinning are required (see Patent Document 2).

  Examples of the mounting location of the above-described ETC on-vehicle device in the passenger compartment include affixing to the console box, each accessory case, or the front console panel.

  Further, in the ETC system, since the ETC card is inserted into the ETC on-board unit and used, it is essential to improve the operability of the ECT card when mounted on the vehicle.

JP 2000-099784 A (page 3, FIG. 1) JP 2001-297348 A (page 4, FIG. 2)

  Therefore, in order to make the ETC on-board device thinner and the operability of the ETC card at the same time, conventionally, as shown in FIG. 11 (a), an electronic component P3 mounted on the internal substrate P2 of the card connector P1 is mounted on the vehicle P4. A method for securing the clearance between the ETC card P6 and the mounting surface P5 by arranging it on the side (the mounting surface P5 side of the vehicle P4) has been known.

  That is, in this case, it is necessary to insert the ETC card P6 face-down into the ETC vehicle-mounted device P8 from the direction of the card contact P7 mounted on the internal substrate P2, and there is a problem that the insertion direction is easily mistaken. .

  As a method for improving this defect, as shown in FIG. 11 (b), there is a method in which the electronic component P13 on the internal board P12 of the card connector P11 is arranged on the outside (opposite side of the mounting surface P14). However, there is a problem that the clearance between the ETC card P15 and the mounting surface P14 is reduced, the ECT card P15 is difficult to grasp, and the operability of the ETC card P15 is lowered.

  As a countermeasure against this, as shown in FIG. 11 (c), there is a method in which a metal bracket P23 is disposed between the ETC vehicle-mounted device P21 and the mounting surface P22 and fixed from the vehicle P24 side with a screw P25 or the like. In this case, since the tip of the screw P25 is visible, there is a problem that it looks bad.

  As another countermeasure, as shown in FIG. 11D, a method of arranging a wedge-shaped spacer P33 between the ETC on-board unit P31 and the mounting surface P32 is conceivable. There is a limit to making the device P31 thinner, and there is a problem that the useless space increases and the ETC onboard device P31 protrudes outward (the product height increases).

  The present invention has been made in view of such a problem, and it is possible to reduce the thickness of the vehicle-mounted device and to ensure high operability of an IC card such as a charge settlement card used in the vehicle-mounted device. It aims at providing the attachment structure of a vessel.

  The vehicle-mounted device according to claim 1 relates to a vehicle-mounted device attached to a vehicle and capable of inserting and removing an IC card along a predetermined movement route. In this vehicle-mounted device, the movement path of the IC card is a vehicle-mounted device. The inclination of the movement path is set so that the distance between the movement path and the vehicle side wall portion increases toward the insertion side of the IC card.

  As a result, in the present invention, even when no spacer is disposed between the vehicle-mounted device and the vehicle, a sufficient clearance can be secured between the IC card and the mounting surface of the vehicle, so that the IC card can be easily grasped. As a result, the product height can be reduced and the operability of the IC card can be improved.

  In other words, in the present invention, since the movement path of the IC card is tilted inside the vehicle-mounted device, the vehicle-mounted device is stretched to the outside as compared with the conventional case where the vehicle-mounted device is inclined or a spacer is arranged. Even if it is not taken out, a sufficient clearance can be secured when operating the IC card. Therefore, high operability of the IC card and suppression of outward protrusion when the vehicle-mounted device is attached can be realized, and the appearance can be improved.

  Moreover, in this invention, the convex part for spaces (for example, base) which protrudes in the vehicle side is provided in the vehicle side wall part of onboard equipment. The space convex portion is set such that the distance between the vehicle side wall portion and the vehicle increases as the IC card is inserted.

  Furthermore, in the present invention, the inside of the space convex portion is hollow, and a plate-like bracket (for example, an attachment member such as a metal bracket) for mounting the vehicle-mounted device to the vehicle is locked to the space convex portion. A mounting opening is provided.

  Further, the space convex portion is provided with a cover portion that partially covers the mounting opening.

  For this reason, it can suppress that dust enters into the vehicle-mounted device from the mounting opening.

  The vehicle-mounted device according to claim 2 is related to the vehicle-mounted device that is attached to the vehicle and capable of inserting and removing the IC card along a predetermined movement path, as in the case of claim 1. The movement path of the IC card is inclined with respect to the vehicle side wall located on the vehicle side in the vehicle-mounted device, and the inclination of the movement path is such that the distance between the movement path and the vehicle side wall becomes larger as the IC card is inserted. Is set to

  As a result, in the present invention, even when no spacer is disposed between the vehicle-mounted device and the vehicle, a sufficient clearance can be secured between the IC card and the mounting surface of the vehicle, so that the IC card can be easily grasped. As a result, the product height can be reduced and the operability of the IC card can be improved.

  In other words, in the present invention, since the movement path of the IC card is tilted inside the vehicle-mounted device, the vehicle-mounted device is stretched to the outside as compared with the conventional case where the vehicle-mounted device is inclined or a spacer is arranged. Even if it is not taken out, a sufficient clearance can be secured when operating the IC card. Therefore, high operability of the IC card and suppression of outward protrusion when the vehicle-mounted device is attached can be realized, and the appearance can be improved.

  Moreover, in this invention, the fitting recessed part by which the bracket (for example, resin bracket) fixed to a vehicle with a screw | thread is fitted is provided in the vehicle side wall part of onboard equipment.

  Therefore, when the vehicle-mounted device is attached to the vehicle, the bracket and the vehicle-mounted device are integrated by fitting the bracket into the fitting recess, so that there is an advantage that the positional deviation hardly occurs and the appearance is good.

  Moreover, the convex part for a joint which protrudes in the vehicle side and is joined to a bracket is provided in the vehicle side wall part of onboard equipment, and the fitting recessed part is provided in the outer peripheral side of this convex part for joining.

Therefore, the vehicle-mounted device and the bracket can be reliably bonded and bonded.

In the vehicle-mounted device according to claim 3, the vehicle-mounted device is used in an automatic toll collection system (ETC system: Electronic Toll Collection system).

  The present invention exemplifies a system to which the vehicle-mounted device is applied.

  -In the mounting structure of the onboard equipment of Claim 4, while a bracket is joined to a vehicle, it is hung on the mounting opening part of the onboard equipment, and is further joined to the onboard equipment.

  The present invention exemplifies the mounting structure of the vehicle-mounted device, whereby the vehicle-mounted device can be securely mounted to the vehicle using a plate-like bracket.

  In the mounting structure of the vehicle-mounted device according to claim 5, the bracket is screwed to the vehicle, is fitted into the fitting recess of the vehicle-mounted device, and is further joined to the vehicle-mounted device.

  The present invention exemplifies the mounting structure of the vehicle-mounted device, whereby the vehicle-mounted device can be securely mounted to the vehicle using the bracket, and the screw portion is made invisible so that it can be mounted. The appearance can be improved.

  In addition, the invention of each claim described above is not limited to the payment of tolls on toll roads using the ETC system, but can also be used for driving-through shopping, gas stations using credit cards, prepaid cards, and other IC cards. It is also possible to apply an automatic fee settlement system or the like in which fee settlement for a pay parking lot or the like is electronically performed by two-way communication between the vehicle-mounted device and the road device.
