Abstract: A content reproduction device has a television broadcast reception function and an Internet connection function, and includes a detection unit and a reproduction-output switching unit. The detection unit detects, when a content of a television broadcast is output for reproduction, a content which is the same as the content of the television broadcast and has a resolution higher than a resolution of the content of the television broadcast from among contents available via an Internet. The reproduction-output switching unit switches a content of the output for reproduction from the content of the television broadcast to the content detected by the detection unit if the detection by the detection unit is successful.

Abstract: A theft detection mechanism is provided with a top ring which is depressed when a foreign object other than a key is inserted into a key inserting hole. A sensor is provided for detecting that the top ring is depressed. A top ring is inevitably pushed down when a foreign object other than a key is inserted into a key inserting hole to activate the sensor, thereby reliably detecting a stealing action. Moreover, the structure of a theft detection mechanism is made simple to reduce the cost thereof.
