  The present invention relates to an electronic device, and more particularly to an electronic device having a hinge mechanism for attaching a member to an apparatus main body so that the member can be opened and closed and rotated.

  2. Description of the Related Art Many electronic devices such as recent imaging devices include a movable image display device that is supported to be openable and closable and rotatable with respect to a device body. In this way, a mechanism for movably connecting the image display device to the apparatus main body is called a hinge mechanism, and the hinge mechanism that enables opening and closing and rotation of the image display device has two rotation shafts for opening and closing and for rotation. Have.

  As such a hinge mechanism, a hinge mechanism as shown in FIG. Usually, the hinge mechanism is provided with a switch or the like for detecting that the image display device has been rotated 180 degrees, and is used for inversion control of the display image. For example, the rotation detection switch rotates in the hinge mechanism so that the convex portion set at a predetermined position of the rotation axis moves with the rotation of the image display unit and turns on the detection switch when rotated by 180 degrees. It is arranged around the rotation axis.
