Abstract: A set top terminal of the present invention includes: a tuner unit for receiving a signal from an external input terminal and selecting a signal of a predetermined frequency; a signal processing unit for decoding the selected signal; a modulation unit for outputting a signal obtained by decoding the selected signal from an external output terminal; a control unit for controlling the tuner unit, the signal processing unit and the modulation unit; a power source unit for supplying power to the tuner unit, the signal processing unit, the modulation unit and the control unit, respectively; and a main board on which the tuner unit, the signal processing unit, the modulation unit and the control unit are placed, wherein the tuner unit, the signal processing unit, the modulation unit, the control unit and the power source unit are separate individual bodies.

Abstract: In order to provide a small-sized card and a connector device therefor having no fear of damages and stains of terminals, the card according to the invention has a structure comprising a casing with an opening, and a double-faced substrate on which electronic parts are provided and a plurality of terminals are attached in the vicinity of one end of the substrate, in which the terminals are provided on both the upper and lower surfaces of the substrate, the lower surface of the substrate is disposed in contact with the inner surface of the casing, the terminals on the lower surface of the substrate are covered with a cover which is swung or slid to be opened/closed freely, so that when the card is inserted in a connector device, the cover is opened to expose the lower-surface terminals and to fit them closely in a connector of the connector device.
