A component supply device including a stage on which electronic components are scattered; a contacting section at a height so as to contact the electronic components on the stage; a slide device to relatively slide the stage and the contacting section; a dropping opening to allow the electronic components scattered on the stage caught by the contacting section to drop in accordance with the relative movement of the stage and the contacting section by the slide device; and a wall at a side opposite to a side of the dropping opening at which the electronic components scattered on the stage drop. The contacting section is provided to extend in a direction perpendicular to a sliding direction by the slide device, and at least a portion of the contacting section is inclined with respect to a straight direction along the sliding direction and an upper surface of the stage.

Component supply device

A loose component supply device including component support memberconfigured to support components in a scattered state; and component supply apparatusconfigured to store components and discharge components towards the component support member from discharge opening, wherein, in the component supply apparatus, conveyor beltis arranged between storage sectionthat stores components and a discharge opening so as to extend diagonally upwards from the storage section on the side on which the discharge section is provided. Components housed in the housing section are discharged from the discharge opening towards the component support member by being conveyed by the conveyor belt. The component supply apparatus is removably mounted on the mounting section. Thus, because components are not discharged from the discharge opening unless the conveyor is operated, components do not fall from the discharge opening when the component supply apparatus is mounted on or removed from the mounting section.

A loose component supply device in which a stage on which components are scattered is imaged by an imaging device and the area of the stage imaged by the imaging device is divided into 20&#xd7;20 blocks. A difference value between first imaging data that is imaging data of the stage without any components loaded and second imaging data that is imaging data of the stage after component supply has been started and components replenished onto the stage is calculated for each block. If the difference value is equal to or greater than a threshold value, it is determined that a component is present in the block, and if it is determined that the quantity of blocks for which it is determined that a component is present is equal to or less than a set quantity, components are replenished to the stage.
