First Claim
Patent Images
1. A telescope comprising:
- an optical system;
a dioptric power adjusting mechanism for driving the optical system to adjust a dioptric power;
a driving source which drives the dioptric power adjusting mechanism;
a specifying member which specifies a position of the optical system corresponding to a predetermined reference dioptric power; and
a controller which controls the dioptric power adjusting mechanism so that the optical system is driven to a reference position specified by the specifying member.

Abstract
A focusing lens for adjusting the dioptric power in accordance with the user'"'"'s dioptric power is provided in each of right and left lens barrels. When a main switch dial is set at a normal position, a microcomputer sets the focusing lens at a dioptric power of 0 by controlling a motor so that the focusing lens moves to a position corresponding to a dioptric power of 0.
