Feeder device and component mounting machine

A power supply control device of a component supply device, the component supply device including a plurality of tape feeders each including a driving device which supplies a taped electronic component to a predetermined position and including a control device that controls the driving device, the power supply control device controlling a consumption current that is supplied from a power supply device to the installed tape feeders, the power supply control device comprising:

• a processor configured to
• acquire a stored value of an operation state consumption current and a standby state operation current for each of the plurality of tape feeders;
• determine a total consumption current by adding each of the operation state consumption currents of the plurality of tape feeders installed in the component supply device;
• and
• control a first tape feeder of the plurality of tape feeders, which is in an operation state where the driving device operates, to transition to a stop state where the first tape feeder is shut off from the power supply device or to a standby state where the operation of the driving device is stopped, when the total consumption current exceeds an output current capacity of the power supply device.
