Portable communication devices

Abstract

The invention relates to a portable communication device. According to the invention, the hinged module comprises a fixed structure with a central part, a guide with edges facing the edges of the central part, and a support adapted to connect the central part and the guide, in which an internal space is created between the central part and the guide, a connecting shaft extends into the internal space through the central part and gears are created on at least one part of the outer circumference of the connecting shaft, and a rotating structure is arranged in the internal space. This rotating structure has a circular arc gear with teeth arranged in a circular arc shape and engaged with the gear, in which the rotating structure rotates around an imaginary axis of rotation passing through the center of the circular arc of the circular arc gear.
