Abstract: The subject technology provides an X-ray shutter apparatus and an X-ray shutter opening and closing system using the same. An X-ray shutter apparatus may be configured to open or close an X-ray shutter using a magnetic field and to accurately control opening and closing of the X-ray shutter using an optical sensor. An X-ray shutter may include a fixing plate, a solenoid fixing block, a frame, a magnet, stop blocks and an exposed block. An X-ray shutter opening and closing system may use an X-ray shutter apparatus.

Abstract: An X-ray shutter apparatus includes a fixing plate; a solenoid fixing block in which upper surfaces of solenoids formed in a cylindrical shape having a hollow hole formed therein are coupled to inner side surfaces of both side surface portions spaced apart from each other and protruding in a C shape and in which an outer side surface of a middle end portion is fixed to one surface of the fixing plate; a frame in which a coupling portion formed at a part of the frame is fixed to the one surface of the fixing plate to be rotatably coupled to the fixing plate, a through portion in which a groove configured to pass through the inside thereof is formed is located on the coupling portion, and a covering plate is fixedly coupled to an end of the lower end portion; a permanent magnet inserted into the through portion to be seated in the groove and having both ends inserted into the hollow holes formed in the solenoids; and an exposed block fixed to the one surface of the fixing plate and in which a path is opened and

Abstract: A device for accommodating an electronic appliance for a vehicle is provided, which includes a housing having a front surface on which an opening is formed, and assembled on a fascia panel in the neighborhood of a head unit to be synchronized; a tray drawn in/out of the housing through the opening and having a connector installed on one side thereof to be connected to the electronic appliance; a slide unit connected between the housing and the tray to make the tray slidingly move against the housing; and a guide rack integrally prepared on a bottom surface of the tray to gradually pop up the tray up to a predetermined angle as the tray is moved forward for a predetermined distance by the slide unit and then is guided along a guide provided in the housing, and to gradually place the tray downward when the tray is slidingly moved backward.

Abstract: A seatback reclining apparatus capable of independently reclining divided seatbacks with different angles. Thereby, interference with a trim of a wheel housing when the seatback is positioned to a flat position is prevented. The seatback includes a reclining shaft provided with a first winding part and a second winding part that is apart from the first winding part with a predetermined distance. The diameter of the first winding part is bigger than that of the second winding part. Around the first winding part, a first spiral spring is provided. The second winding part is provided with a second spiral spring whose number of winds is greater than that of the first spiral spring.
