Component supply device and tape feeder

A component supply device comprising:

• a plurality of kinds of tape feeders configured to supply components stored in component storing tapes to a predetermined component takeout position, the tape feeders being configured to mount and feed a first component storing tape by which supplying of components is performed precedingly, and a second component storing tape by which supplying of components is performed succeedingly;
• a component sensor configured to detect runout of the components in the first component storing tape;
• a controller configured to control a tape feeding operation of the first and second component storing tapes in the plurality of kinds of tape feeders;
• and
• a memory configured to store a specified discharge length by which the first component storing tape is discharged from the tape feeder when the runout of the components occurs, the specified discharge length being preliminarily set for each kind of the tape feeder,
• wherein
• the controller is configured, when the component sensor detects the runout of the components of the first component storing tape, to read the specified discharge length from the memory, to make the tape feeder perform the tape feeding operation for feeding the first component storing tape by the specified discharge length, and to make the tape feeder finish a tape discharging operation of the first component storing tape when the tape feeding operation by the specified discharge length is completed.
