Abstract: A receiving device includes a board on which components for receiving a digital broadcasting signal are mounted; a non-conductive casing configured to accommodate the board; and a non-conductive lid configured to cover the board and being connected to the non-conductive casing, wherein the board has a conductive portion located in an edge portion of the board facing a gap formed in a connecting portion between the casing and the lid.

Abstract: A receiving device includes a circuit board having mutually opposite first and second surfaces, the circuit board including a tuner mounted on the second surface to receive a digital broadcasting signal, a decoder IC mounted on the first surface to convert an intermediate frequency signal output from the tuner into analog video and audio signals, and a power supply circuit mounted on the first surface to supply a power source voltage to the decoder IC via a power supply path, and a plurality of capacitors mounted on the circuit board and connected in parallel to the power supply path. The plurality of capacitors include first-group capacitors mounted on the first surface and second-group capacitors mounted on the second surface in an area of the circuit board defined by an orthogonal projection of the decoder IC on the first surface onto the second surface.

Abstract: A receiving device includes a case body having an insertion slot of a contact IC card formed in the case body, a tuner arranged in the case body to receive a digital broadcasting signal, and a digital circuit board arranged in the case body to accommodate the tuner mounted on the digital circuit board. In the receiving device, the digital circuit board is arranged to include a debugging circuit pattern formed in a predetermined area at an end portion of the digital circuit board, the debugging circuit pattern being arranged to connect an integrated circuit mounted on the digital circuit board to a debugging circuit for debugging of the integrated circuit.

Abstract: A receiver includes a case main body with an opening for inserting an IC card; an electric power supply board provided in the case main body; a contact type IC card connector where the contact type IC card is expected to be connected; and a tuner configured to receive a digital broadcasting signal, wherein the contact type IC card connector is provided in a position so that an entirety of the contact type IC card is received in the case main body in a case where the contact type IC card is inserted through the inserting opening on the electric power supply board; and the tuner is situated in a position between the inserting opening and the contact type IC card connector, the position being where the tuner does not come in contact with the contact type IC card in the case where the contact type IC card is inserted.

Abstract: An electrostatic discharge protection structure of an electronic device is disclosed. The electronic device includes an electrically insulating panel and an electrically insulating operation member fitted with respect to an opening of the panel. The operation member includes an operation member main body, a flange extending from the operation member main body, and a groove formed along a peripheral surface of the operation member main body in a face of the flange opposing the panel. The panel includes an enclosing rib along the edge of the opening on a back face thereof. The operation member is configured such that the operation member main body is fitted with respect to the inner side of the enclosing rib of the panel, and the groove is fitted with respect to the enclosing rib of the panel.
