Description

The present invention relates to an ETC (Electronic Toll Collection: automatic toll collection system) vehicle-mounted device, and more particularly to an ETC vehicle-mounted device that communicates with an ETC roadside device using a narrowband communication system such as DSRC (Dedicated Short Range Communications).

In ETC on-board units, IC (Integrated Circuit) cards called ETC cards are inserted and charges are settled. From the viewpoint of security such as prevention of theft of IC cards, IC cards are externally installed as much as possible. There is a request to make it invisible. For this reason, the conventional ETC vehicle-mounted device has a structure in which the IC card is hidden in the vehicle-mounted device body as much as possible when the IC card is inserted. However, since the user pushes the IC card into the ETC vehicle-mounted device with his / her finger when inserting the IC card, the IC card has to be partly protruded from the vehicle-mounted device body. Alternatively, the ETC in-vehicle device is hidden and installed in an invisible part of the vehicle to cope with security such as prevention of theft of the IC card.

On the other hand, in recent years, there is a large demand for a thinner ETC vehicle-mounted device, and the thinner vehicle-mounted device main body is progressing. However, if the vehicle-mounted device body is made too thin, the clearance between the mounting surface of the mounting stay and the IC card insertion slot becomes narrow, and the IC card insertion / extraction operability deteriorates.

By the way, the method of making the mounting angle of an onboard equipment main body variable by the mounting stay holding an onboard equipment main body is already well-known (for example, refer patent document 1). However, this method makes the mounting angle of the vehicle-mounted device main body variable in order to optimize the radiation direction of the antenna, and this is not intended to improve the operability of inserting and removing the IC card. At times, it was impossible to reduce the thickness of the vehicle-mounted device body.

When the front portion of the vehicle-mounted device body 1 is slightly lifted from this IC card storage state and the catches of the tilt pins 1a, 1a at the notches 2a1, 2a1 are released, the vehicle-mounted device body 1 is moved backward by the elastic elasticity of the spring 5. Is automatically slid to the IC card insertion / removal state. For this reason, the front end part of the IC card 4 protrudes from the IC card insertion port 1c at the same time that the IC card insertion port 1c of the vehicle-mounted device body 1 is tilted up.

According to the second embodiment, if the front portion of the in-vehicle device body 1 is lifted up slightly, the tilt pins 1a, 1a of the in-vehicle device body 1 are released from the hooks to the notches 2a1, 2a1 of the tilt long holes 2a, 2a. The in-vehicle device body 1 is automatically slid rearward by the elastic force of extension of the spring 5, and the IC card insertion slot 1c of the in-vehicle device body 1 is tilted up. At the same time, the front end of the IC card 4 extends from the IC card insertion port 1c. Since it protrudes, in order for the user to take out the IC card 4, the trouble of pushing the vehicle-mounted device main body 1 backward with respect to the mounting stay 2 becomes unnecessary.
