[0005]

However, the above-described method of creating component substitute data has the following problems.

1) An operator must manually confirm the positional relationship of the component supply device on the operation panel 12 and the monitor screen 13 and manually input the component replacement data. Hundreds of component supply devices are installed, which takes a lot of time and may cause erroneous input.

2) When the component supply device removed from the electronic component mounter is installed again, effective data cannot be created because the number of mounted components is unknown.

In view of the above-mentioned problems of the prior art, the present invention automatically creates the component replacement data at the completion of the installation of the component supply device, thereby reducing the load of the operator's data creation and the data creation time. The purpose is to improve the operation rate and the implementation quality by preventing data creation mistakes.
