Abstract
Abstract A pager includes a display mounted on the front side of a pager housing. On the back side of the housing is mounted a clip which is used for carrying the pager on the user's belt. The display displays a received message and inverts the displayed message in response to a switch signal. The inverted message is reflected at a foldable mirror to produce a noninverted message that the user can see from the upper side of the housing. A switch produces the switch signal to invert the displayed message with the unfolding movement of the foldable mirror.
