Abstract: In a television receiver having a decryption unit and a video display unit which are stored in one casing, copyright protection is given to an encrypted digital video signal or analog video signal. When an encrypted digital video signal is inputted to a digital video signal input terminal, the signal is decrypted by a decoding circuit to obtain an after-decryption video signal that is copiable, and thereafter, the signal is visualized by a video display unit. When a casing cover is opened, a decoding control circuit converts a parameter that is needed for decryption, such as an encryption key, into a meaningless parameter, and outputs it to the decoding circuit, whereby the after-decryption video signal becomes a video signal that is not decrypted. On the other hand, during maintenance, a predetermined code is inputted from a button group (18) to output a regular decryption parameter to the decoding circuit (13).

Abstract: A high-frequency bias supply circuit includes a plurality of bias supply lines each of which is connected in parallel with others between a corresponding one of selected points along the main signal line and a common bias supply terminal. Each of the bias supply lines has a length and a distance from an adjacent bias supply line different from those of others, the length and the distance being in a range of a 1/3 to 3/8 wavelength of the center frequency.

Abstract: An article includes a body member and a detachable member detachably attached to the body member. One of the body member and the detachable member includes a cover portion having an engaging portion on an inner wall face of the cover portion. The other includes a covered portion that is covered with the cover portion and has an engaged portion on an outer wall face of the covered portion. The engaging portion and the engaged portion are configured to be disengaged by warping the cover portion so that the cover portion displaces to an outer wall face side of the cover portion. The one of the body member and the detachable member includes a finger-applying-position indicator at a position deviated from a portion corresponding to the cover portion, on an outer wall face of the one. The finger-applying-position indicator indicates a position to be applied with fingers of a user.

Abstract: An automatic document feeder, which is included in an image reading device and an image forming apparatus, includes first and second document trays, a document output tray, a document conveying passage, multiple document conveying bodies, a drive source, a detector, and a controller. The multiple document conveying bodies include a document holding and conveying body to convey and hold the original document sheet on the second document tray. On detection of the original document sheet on the second document tray while conveying a different original document sheet from the first document tray, the controller stops feeding the different original document sheet, causes the different original document sheet downstream from the document holding and conveying body in a document conveying direction to be conveyed to the document output tray, and stops the drive source after the different original document has been conveyed to the document output tray.
