Abstract: A washing machine includes a dewatering shaft for rotating a washing tub, a drive shaft for rotating a pulsator in the washing tub, a coupler configured to move along the dewatering shaft to couple or decouple the drive shaft and the dewatering shaft, a solenoid configured to move the coupler, and a coupler guide configured to be rotated by contact with the coupler or to maintain the coupler in the second position. The coupler includes locking protrusions configured to lock onto an upper side of the coupler guide. The coupler guide includes first guide projections disposed on an outer perimeter of the coupler guide and configured to contact one of the locking protrusions to rotate the coupler guide, and second guide projections disposed opposite to the first guide projections and configured to contact another of the locking protrusions to rotate the coupler guide.

Abstract: In the present disclosure, a structure of a 3-dimensional space measurement device is maximally simplified to be easily carriable by a user to measure a 3-dimensional spatial data. For simplifying the structure, a light transmission unit and a light reception unit are fixed to a support plate, and the support plate is fixed to a rotation unit. Provided are a 3-dimensional space measurement device capable of adjusting a rotation angle of the rotation unit and a tilt angle of the support plate to efficiently measure a distance and space, and a measurement method of a distance and space for making 3-dimensional spatial data.
