Abstract: A mobile phone handset includes a mode switching unit and a configuration detection sensor, so that the operating mode of the mobile phone handset can be switched. The mode switching unit has a switching program installed, and is a computer for executing a prescribed process in accordance with the switching program when a signal is input from the configuration detection sensor. The configuration detection sensor is a sensor for detecting the configuration of the mobile phone handset, and for example may use an angular sensor for detecting the relative angle about a rotation axis between a first casing and a second casing.

Abstract: A cellular phone device has an operation-unit casing, a sliding casing which is coupled to the operation-unit casing with the front face of the sliding casing facing the rear face of the operation-unit casing, and which slides with respect to the operation-unit casing in a direction parallel to the rear face of the operation-unit casing, and a direction input device provided on the rear face of the operation-unit casing. The sliding casing slides with respect to the operation-unit casing between a state where the direction input device is covered by the sliding casing and a state where a covering of the direction input device by the sliding casing is released.

Abstract: In a foldable cellular phone, a cross key is provided on an operating surface of a second casing and a side right-and-left key having the same function as two direction keys of the cross key is provided on one side surface of the second casing. Further, a side up-and-down key having the same function as the other two direction keys of the cross key is provided on a side surface of a first casing that is positioned on the same side as the side right-and-left key when the foldable cellular phone is folded in such a way that the display section faces to the outside.

Abstract: An adapter for mounting an optionally-additional functional component onto a mobile wireless communication device (on which a battery for electrically energizing the mobile wireless communication device is mountable), comprises a joint portion connectable to the mobile wireless communication device so that the adapter is attached through the joint portion to the mobile wireless communication device in a removable manner, and a component holding portion adapted to hold the optionally-additional functional component on the component holding portion.

Abstract: An arc cam member has a guide groove formed on its underside along its arced length. On its outer circumference, the cam member is provided with a first cam portion. A second cam portion is formed in the wall of the guide groove of the cam member. The ends of a first arm and a second arm are placed in contact with the first and second cam portions respectively. As the cam member is rotated, the first and second arms move, following the shapes of the first and second cam portions. The motion of the first and second arms is used to operate the recording and reproducing apparatus.

Abstract: A tape loading mechanism of a video tape recorder includes a tape guide carrier for driving first and second groups of tape guides for pulling out withdrawing a tape from a cassette and winding the tape to a tape guide drum having an arcuate shape so as to rotate around the tape guide drum and drive the tape guide groups. The tape guide groups are mounted to end of the tape guide carrier and the carrier is disposed at the intermediate position of height between the first and second tape guide groups held by a positioning mechanism. Accordingly, the rotating plane of the tape guide carrier rotating around the guide drum is positioned between the first and second tape guide groups.

Abstract: A cassette loading apparatus is disclosed in which a guide slot is formed in one of a cassette receiving portion for receiving and holding a tape cassette in place and a base plate fixed to a chassis, and an engagement portion for engaging with the guide slot is formed in the other. On each side of the apparatus, there is provided a pivotable link between the cassette receiving portion and the base plate.
