SELECTIVE CALL DISPLAY RECEIVER HAVING INTERNALLY MOUNTED PAIRED LENSES

FIELD OF THE INVENTION

  This invention relates in general to the field of selective call receivers, and more specitically to selective call display receivers capable of displaying information on a display,

BACKGROUND OF THE INVENTION

  Many selective call display receivers (e.g. display pagers), communicate information to a user by display- ing messages on a display. The display normally has fixed dimensions.

  Regrettably, certain segments of the user population may have d&&y viewing the display at a normal viewing distance. Some individuals are able to easily focus and read a message on the display at a normal viewing distance. While, other individuals are not able to focus and read the same message. Focusing distance also normaUy increases with age. As the focusing distance increases the size of the displayed message must also increase to maintain the same subtended visual angle in relation to an image size on the retina. Often, the size of the message is too small for the user's normal viewing distance.

  Thus, it is unfortunate that no known selective call display receiver aIlows a user to adjust the magCIication of an image on the display to suit the user's visual acuity.

DESCRIPTION OF THE PREFERRED EMBODIMENT

  Referring to FIG. 1, a cut-away side view of a selec- tive call display receiver is shown. The selective call dis- play receiver comprises a housing 102 and a display 104 fixedly mounted thereto. A user of the selective call display receiver can view the display 104 through a pair of lenses 106,108, as discussed below.
