ABSTRACT:
A hinge device of a portable intelligence terminal, which connects a first member having a keyboard and a second member composed of a comparatively massive display device in an openable and closable manner as well as possible includes a cam mechanism and a friction mechanism coaxially on a shaft. The cam mechanism is structured with a fixing cam provided by allowing a shaft to insert through axially at each central portion into a cam case having a rotation arresting means fixed on the shaft, a slider cam provided slidably in a manner to confront to the fixing cam, being restrained its rotation by the cam case, and an elastic means to press the slider cam toward the fixing cam side, and the friction mechanism is structured with a friction ring attached to the shaft and fitted into the friction case with pressure having a rotation arresting means attached to the shaft in a manner to be rotatable, so that both of automatic closed lock function from a predetermined closed angle between the first and second members and a free stop function when opening and closing operation of the first and second members can be realized together without strain.
