A loose component supply device including: component support member 150 configured to support multiple components in a scattered state; component collection container 180 configured to collect the components supported on the component support member via an opening in the component collection container; and a container oscillating device configured to scatter the components collected inside the component collection container onto the component support surface by swinging the component collection container such that the opening of the collection container faces the component support member. By this, because components are scattered on the component support member directly form the component collection container, the cycle time is shortened, thereby improving practicality of a component supply device.
