Loose component supply device and component mounter

A loose component supply device comprising:

• a loose component support section that supports multiple of the same type of components in a loose state;
• an imaging device that images the multiple components in the loose state supported on the loose component support section, the imaging device being mounted on either a main body of the loose component supply device or an imaging device moving device, above the loose component support section;
• a plurality of component holding tools capable of picking up and holding the multiple components in the loose state supported on the loose component support section;
• a component holding head which holds one of the plurality of component holding tools;
• a holding head moving device that moves the component holding head at least and from the loose component support section and a component transfer section at which transfer to a next process is possible;
• and
• a holding tool changing device that changes the one of the plurality of component holding tools held by the component holding head to another of the plurality of component holding tools based on image data obtained by the imaging of the imaging device,
• the loose component supply device picking up each of the multiple components in the loose state supported on the loose component support section and arranging the multiple components in a predetermined orientation on the component transfer section.
