A loose component supply device provided with: a stage configured to support scattered components; a holding tool configured to hold a component scattered on the stage; and a component reception member in which is formed a component reception recess in accordance with the component, the device supplying components in a state with the component held by the holding tool loaded in the component reception recess of the component reception member. With the loose component supply device, a setting section is provided for setting any of multiple of the component reception members. An identification plate is provided on the component reception member and a 2D code for identifying the type of the component that is able to be loaded in the component reception recess is provided on the identification plate. Thus, it is possible to confirm the type of component that is in accordance with the component reception member set on the setting section and to reliably set a component reception member that is in accordance with the component scheduled to be supplied on the setting section.

The exposure head is for irradiating a substrate conveyed in a predetermined direction with an exposure beam while scanning the substrate with the exposure beam in a one-dimensional manner, and the exposure head includes: a polygon mirror having multiple reflecting surfaces and provided rotatably; an optical element configured to cause the beam emitted from a light source and shaped into a beam shape to enter the polygon mirror; an imaging optical system configured to image the beam reflected by the polygon mirror onto an exposure surface of the substrate, a reflecting mirror provided insertably into or removably from the optical path of the beam shaped into the beam shape entering the optical element, the reflecting mirror being configured to reflect the beam in a direction different from the optical path while being inserted into the optical path; and a light-receiving element arranged at a position where the beam reflected by the reflecting mirror can enter the light-receiving element, and that is capable detecting an intensity of the beam.

A component supply device that images stage on which multiple leaded components are supported in a scattered state, and holds a component supported on the stage using a component holding tool based on the image data, wherein multiple stages of different colors are prepared, and a stage from among the multiple stages a stage with a color different to a component that is planned to be supplied is removably attached to component support member. By this, for example, in a case in which a component planned to be supplied is white, by attaching a black stage to the component support section, due to the contrast between the background and the target object, it is possible to clearly recognize the white component supported on the black stage.

A component supply device includes a transport path that guides a component connected body from a component insertion port on an upstream side in a component feeding direction to a component supply position on a downstream side, the component connected body including a plurality of axial components arranged and connected at a predetermined pitch, the plurality of axial components each having a lead, and a feed mechanism that pitch-feeds the component connected body along the transport path to the downstream side. The feed mechanism includes a feed member which has a plurality of feed hooks disposed at the predetermined pitch along the component feeding direction, a rotating shaft which is connected to one end side of the feed member, and a moving mechanism which is connected to the feed member through the rotating shaft and reciprocates the rotating shaft along the component feeding direction. A length of one feed hook among the plurality of feed hooks is longer than a length of an other feed hook among the plurality of feed hooks, the other feed hook being adjacent to the one feed hook on the rotating shaft side.

A component supply device including a component storage device that stores a plurality of components, a component support member on which the components from the component storage device are dispersed, and a component return device that returns the components on the component support member to the component storage device, is provided. In a case where the necessary number of components exceeds the number of holdable components, return work of the components to the component container and dispersal work of the components to the component support section are carried out prior to holding the components from the component support section by the component holding tool.

For a component receiving member provided with a component reception recess shaped according to a component that is a storage target, and side wall section that a component held by suction nozzle contacts when moved in the left-right direction, when the component is released in a state contacting the side wall section, the component is stored in the component reception recess by leads of the component falling along a tapered surface and the component rotating 90 degrees due to its own weight. Therefore, even in a case in which the component is held by suction nozzle with an upper surface facing up, the component is stored in the component reception recess with the upper surface facing up by the component rotating 90 degrees at the component receiving member.
