Disclosed herein is a bar-type wireless communication terminal, and a rotary type hinge device thereof. The bar-type wireless communication terminal comprises a lower body and an upper body. The lower body is installed at its one side surface with a camera lens unit, and at its front and rear surfaces with first and second keypads, respectively. The upper body is coupled to the upper end of the lower body so that it is rotatable in a twisting direction relative to a rotation axis extending in a longitudinal direction of the lower body. The upper body is installed at its front surface with a display device. According to the bar-type wireless communication terminal constructed as stated above and a rotary type hinge device thereof, it is possible to provide the user with a wider choice of the terminals. In addition, in conjunction with a display device and a camera lens unit additionally installed to the wireless communication terminal, the image display direction of the display device as well as an aim direction of the camera lens unit can be set at various different angles, thereby allowing the user to conveniently utilize the wireless communication terminal for image capturing and video communications.
