Patent ID: 7006285

Claim:
A pair of range binoculars which comprises: a first observation optical system comprising a first optical member for forming an erecting image, a first objective optical system that together with said first optical member determines a first objective optical axis, and a first ocular optical system that determines together with said first optical member a first ocular optical axis; a second observation optical system comprising a second optical member for forming an erecting image, said second member being placed parallel with said first optical member, a second objective optical system that determines together with said second optical member a second objective optical axis, and a second ocular optical system that determines together with said second optical member a second ocular optical axis; a main case accommodating said first optical member, first objective optical system, first ocular optical system, and said second objective optical system, wherein said first optical member, first objective optical system, first ocular optical system, and second objective optical system are fixed in said main case so that they do not move when pupil distance is adjusted; an attached case accommodating said second ocular optical system and said second optical member, said attached case being placed on said main case so that said attached case turns round said second objective optical axis; laser range-finding means accommodated in said main case; and measured distance displaying means comprising LCD means for displaying a distance measured by said laser range-finding means, said LCD means being placed at a part off a light path formed by said first observation optical system, and a displaying optical system for projecting the distance displayed by said LCD means on a reticle so that the distance is shown at a rim of the visual field.
