The present invention provides a hinge device (5) which permits opening and closing operations to be carried out smoothly and with surety, and which contributes to the design of a more compact device. The hinge device (5), wherein a transmitter is connected to one lateral edge (4) of an operational member (2) in a freely opening and closing manner, comprises two hinge device main bodies (6). These hinge device main bodies (6) are disposed to either end of the lateral edge (4) along the longitudinal direction thereof, and are provided with a cam shaft (7) and a spring (8) respectively. The cam shaft (7) is affixed to the operating member by positioning the axis thereof parallel to the lateral edge (4). In addition, the cam shaft (7) is provided with a cam portion (10) at its axis periphery. A spring (8) is affixed to the transmitter (3), and the cam portion of the cam shaft is elastically held. <IMAGE> |
