PROBLEM TO BE SOLVED: To provide an electronic part transfer device which can select and rotate a part holding tool by one driving source without generating position deviation of electronic parts. SOLUTION: A sheath axis 138 which can rotate around a perpendicular axis line supports as a head holding body 154 being able to rotate around a horizontal axis line. A middle axis 14 which is so fixed with the sheath axis 138 as being relatively able to rotate is junctioned with a servomotor 192 for nozzle rotation and selection, driving side junctioning member 202 and drived side junctioning member 232 transmit rotations of the servomotor 192 for nozzle rotation and selection to the sheath axis 138 and elevation and descending of a motor holding base 210 switches conditions of rotation transmission or rotation non-transmission. Under the condition of the rotation transmission the middle axis 144 and the sheath axis 138 rotate, and under the condition of the rotation non-transmission the middle axis 144 only rotates and the nozzle holding body 154 rotates to select a part clamping nozzle 158. Rotations of the servomotor for nozzle rotations may be changed to rotations of the nozzle holding body by a cam and a cam follower. |
