Component mounting system

A component mounting system comprising:

• a component mounter that mounts a component in a board;
• a component feeder that is placed in the component mounter and supplies the component;
• and
• a mobile component supply device that holds at least one container storing a component, automatically moves, and supplies the component in the at least one container to the component feeder,
• wherein the component mounter includes a container holding device having a first holding position for holding the at least one container, and a second holding position for holding the at least one container supplied prior to the container held at the first holding position,
• wherein the mobile component supply device includes a container housing unit that collects the container held at the second holding position when the component stored in the container is consumed,
• wherein the component mounter includes a guide that moves the container held at the first holding position from the first holding position to the second holding position when the container housing unit collects the container held at the second holding position,
• wherein the guide is a groove formed in an inner wall of the container holding device, and
• wherein the groove is extended downwardly to allow the container to move downwardly due to gravity from a top of the container holding device to a bottom of the container holding device along the inner wall of the container holding device.
