An automatic picking conditions regulating device regulates the picking conditions of one of the same of a picking device having a picking nozzle which picks a weft yarn by jetting a pressurized picking fluid, in order to pick a weft yarn so that the same arrives at a predetermined position at a target weft yarn arrival crankshaft angle. When the weaving conditions of the loom are changed, a picking condition, such as the pressure of the picking fluid or the jet starting crankshaft angle, is varied sequentially, the corresponding actual weft yarn arrival crankshaft angles are measured, and then the values of the controlled picking condition and the measured actual weft yarn arrival crankshaft angles are used to determine an optimum value of the picking condition for making the actual weft yarn arrival crankshaft angle coincide with the target weft yarn arrival crankshaft angle. A series of the picking condition regulating operations are carried out during the trial picking operation and/or during the normal weaving operation of the loom.
