Electronic component mounting system and electronic component mounting method

This invention is directed to prevention of setting a component feeding unit set with other storage member than a storage member storing same type of components as components in shortage in an electronic component mounting apparatus. A component mounting apparatus sends notice information about component shortage to a control computer (30) when a number of electronic components in a storage member reduces and reaches a level for sending the notice information of component shortage during mounting operations. The control computer (30) stores the notice information, and sends the notice information to a monitor computer (32) to display this information on a monitor (33). A new storage member having the corresponding components is set in the component feeding unit based on the displayed notice information, and an operator inputs information A about which component feeding unit is set with the storage member and which components are stored in the storage member set in the component feeding unit. The monitor computer (32) sends the information A and information about completion of registration of a relation between the component feeding unit and the components to the control computer (30), and the control computer (30) stores this information in a memory (41) and sends the information about registration to the monitor computer (32), and the monitor (33) displays the notice information in a different color.
