Abstract: A hinge mechanism for a foldable portable telephone is disclosed. The hinge includes a first cylindrical member coupled to a main body portion and a second cylindrical member coupled to a foldable portion. The first cylindrical member has a first cylindrical hollow formed therein and the inner side wall of the first cylindrical hollow has positioning recesses formed in a predetermined pattern corresponding to the opened and closed positions. The second cylindrical member has a second cylindrical hollow formed therein and a plurality of holes formed in a side wall thereof. The second cylindrical member is rotatably fit in the first cylindrical hollow of the first cylindrical member. An elastic cylinder is fit in the second cylindrical hollow. A hard ball freely fit in each of the holes and the hard balls fit in the holes are pinched between the elastic cylinder and the inner side wall of the first cylindrical hollow to allow each sphere to be fit into a corresponding one of the positioning recesses.

Abstract: An output terminal structure for electrically connecting a paging receiver in a printer capable of printing out information received by the receiver. A retaining portion is formed integrally with a case of a battery containing portion which is included in the paging receiver. Connecting pieces each is implemented as a thin flat piece of metal and provided with a single leg. Each connecting piece is received in respective one of slots which are formed in the retaining portion, and the leg of the connecting piece is soldered to a printed circuit board which is incorporated in the receiver. Each connecting piece has a contact surface that contacts a contact terminal member provided in the printer through a window which is formed through the retaining portion, thereby electrically connecting the receiver to the printer.
