A hinge device for a foldable electronic apparatus. The hinge device includes an elongated main frame that extends along a first axis. A hinge unit includes an elongated pivot rod extending along the first axis and having a pivot end portion coupled pivotally to a stationary fixing block such that the pivot rod is rotatable axially about the first axis, and a connecting end portion connected to the main frame. A pivot unit includes an elongated pivot shaft extending along a second axis transverse to the first axis, and a pivot member coupled pivotally to the upper end portion of the pivot shaft, and adapted to be mounted on a cover member of the electric apparatus. A positioning unit is mounted on the cover member and is operable so as to engage the elongated main frame for preventing axial rotation of the cover member about the second axis.
