Abstract
An assembly jig for assembling a phase-modulation-type optical fiber gyro has a reel support area for supporting a fiber coil reel with an elongate optical fiber wound therearound and a coupler reel with optical fibers from a coupler wound therearound, the fiber coil reel and the coupler reel being rotatably supported on a base plate of the assembly jig through a support shaft. The assembly jig also has a chip support base disposed on the base plate for temporarily supporting thereon the optical IC chip optically connected to the optical fibers, a package housing support base disposed on the base plate for supporting a package housing of a package to encase the optical IC chip therein and substantially packaging the optical IC chip with the package housing, and a lid support base disposed on the base plate for supporting a lid to cover the package housing. The assembly jig allows the optical fiber gyro to be assembly easily at a reduced cost.
