ABSTRACT:
A tape feeder feeds electronic components by advancing a tape intermittently. The tape feeder comprises a motor controller for controlling a motor, which rotatively drives a sprocket to advance the tape, and a communication unit for receiving a control signal from a control unit of an electronic component mounting apparatus and transmitting a control parameter such as a rotating speed, an amount of rotation, and acceleration and deceleration pattern to the motor controller. The tape feeder has such a structure that a tape advancing speed and an amount of tape advancement are easily changeable according to a type of the electronic components by changing the control parameter of the rotating speed and the amount of rotation of the motor. In addition, the tape feeder is adaptable for correction of the amount of rotation according to a result of measurement of pin position of the sprocket, so as to properly interrupt turning of the sprocket at the correct stop position for accurate positioning of the electronic components into the right pick-up location all the time.
