Claim of US Patent No. 9,992,919

1. An electronic circuit component mounting system comprising:a component supplying device that supplies an electronic circuit component;
a target member holding device that holds a mounting target member to which the electronic circuit component is to be mounted;
a mounting device that includes a component holding tool which holds the electronic circuit component and includes a lifting and lowering device which lifts and lowers the component holding tool, the mounting device receives the electronic circuit component from the component supplying device using the component holding tool, and mounts the electronic circuit component on the mounting target member held by the target member holding device; and
a damage detecting device that detects that the electronic circuit component is damaged in at least one of when the component holding tool contacts the electronic circuit component by the component holding tool being lowered by the lifting and lowering device, and when the electronic circuit component held by the component holding tool contacts the mounting target member by the component holding tool being lowered by the lifting and lowering device, the damage detection device including a reaction force detecting section that detects a reaction force against the component holding tool in at least one of when the component holding tool contacts the electronic circuit component, and when the electronic circuit component held by the component holding tool contacts the mounting target member,
wherein the reaction force detecting section includes a drive source current detecting section that detects a current of a drive source of the lifting and lowering device as an amount corresponding to the reaction force against the component holding tool.
