PURPOSE:To provide, at low costs, an electronic-component holding device in which an electronic component is held selectively by using a plurality of suction nozzles. CONSTITUTION:When a rod 178 is lowered, a second coupling member 204 is coupled to a nozzle holding body 84. When a driving lever 230 is turned in this state, the nozzle holding body 84 is turned via the second coupling member 204, and one out of a plurality of suction nozzles held by the nozzle holding body 84 is moved to its use position. The second coupling member 204 is coupled and detached in such a way that a lever connected to a rod 178 is turned by a cam. The nozzle holding body 84 is turned to a direction and by an angle in and at which the suction nozzle which is used next is moved to its use position when a roller is coupled selectively to the right and left groove wall faces of two grooves which have been formed so as to be overlapped with a grooved cam and whose depth and width are different. |
