An IC card connector capable of handling an IC card having embossed data rows with a simple and small-size structure of high mechanical strength is provided. The IC card connector includes a connector body for accommodating an IC card having a contact array and embossed data rows. An IC card receiving port is provided at one end of the connector body for receiving the IC card. A guide mechanism is provided along both sides of the IC card receiving port for guiding insertion of the IC card and grooves are formed in portions of the connector body along the direction in which the IC card is inserted so that the embossed data rows can move through the grooves.

A device for mounting boards, which requires decreased positioning precision for inserting the boards, offering improved operation efficiency and reliability without driving up the cost. The device for mounting boards includes a case body,having board guide grooves,formed in the inner surface thereof, and a case closure,secured to an end of said case body, in order to position and secure the circuit boards in a housing constituted by the case body and the case closure, wherein the board guide grooves have a uniform width w slightly larger than the thickness of the circuit boards and have tapered portions,of which the width is broadened toward an end of the case body opposed to the case closure, and the case closure has securing pawls,which produce elastic force in a direction to be fitted to the case body, and board-holding portions,for positioning and holding the ends of the circuit boards. The circuit boards are smoothly and correctly inserted in the board-guide grooves through the tapered portions.

An ETC car-mounted equipment which can be attached to an existing room mirror in a vehicle and enhances operability for inputting the data impairing neither the communication function nor the visual range for operation. An ETC car-mounted equipment exchanges ETC data relative to an ETC road equipment, and comprises a main body 13 of the car-mounted equipment having a display unit for displaying the ETC data, an IC card insertion port 16 formed in the main body of said car-mounted equipment and in which will be inserted an IC card that stores said ETC data, a mirror unit 14 provided on the front surface of the main body of said car-mounted equipment, an antenna unit 15 provided on the back surface side of the main body of said car-mounted equipment, and resilient holding units 21 for holding the main body of said car-mounted equipment on a room mirror in the vehicle integrally therewith.

ETC car-mounted equipment

An antenna device realized in a small size and at a decreased cost owing to a reduction in the feeder circuits and in the harness portion. The antenna device includes a plurality of antenna units 11 to 18 integrally arranged neighboring each other, and a core unit 20 arranged integrally with said antenna units to feed electric power to said antenna units, wherein each of said antenna units and said core unit has detachable joining/securing portions and connector portions, and each of said antenna units is electrically connected to said core unit via said connector portions. The antenna units required by a user are divided into blocks for each of the functions and are selectively utilized in an aggregated manner.
