摘要： For use in an optical instrument having two objective optical axes the spacing between which is variable, a magnification varying device includes a pair of members for changing the spacing between the two objective optical axes. A pair of magnification varying members are rotatably mounted on the spacing changing members by means of rotary shafts for successively moving lenses of any desired magnifications into alignment with the two optical axes. A pair of supporting members, each having at least one articulation, are provided so that one end of each of the supporting members are pivotally connected to the rotary shaft of each of the magnification varying members and that the other ends of the supporting members are pivotally connected to an operating member which is rotatably mounted to the body of the device. A pair of rotation transmitting members are supported by the supporting members to transmit rotation of the operating member to the respective magnification varying members.
