Abstract
The invention provides a component feeding device where heat generation of a drive circuit is minimized and a printed board mounted with this drive circuit is miniaturized by forming an inexpensive structure using a single microcomputer and by energizing each of the servomotors only when necessary. In a component feeding unit of a dual lane type, a CPU in a microcomputer controls a start of driving of one of servomotors by energizing the servomotor through a drive circuit based on a component feeding signal for one lane outputted from a CPU of an electronic component mounting apparatus, and the CPU in the microcomputer controls one of the servomotors so that the servomotor is not energized when a component feeding signal for another lane is inputted before a predetermine time passes after a delay timer starts timekeeping when receiving a detection signal about rotation of the servomotor by a predetermined amount from an encoder detecting a rotation amount of the servomotor.
