Component supply apparatus

1. A component supply device, configured to supply an electrical component, comprising:

multiple placement sections, in which an electrical component positioned by a positioning section is placed, the placement sections each being movable in a conveyance direction, and

a detection device which is configured to detect displacement in an up-down direction of the electrical component being placed in the placement sections, the up-down direction being perpendicular to both the conveyance direction and a front-rear direction of the component supply device,

wherein the detection device includes a light emitting section that emits light and a light receiving section that receives the light, the light emitting section and the light receiving section facing each other in the front-rear direction.

2. The component supply device of claim 1 , wherein the detection device detects the displacement in the up-down direction of the electrical component placed in the multiple placement sections using a laser or light.

3. The component supply device of claim 1 , wherein the positioning section positions the electrical component, placed in each of the multiple placement sections, with respect to at least a lateral face of the electrical component.

4. The component supply device of claim 1 , wherein the placement sections position and place the electrical component so that top surfaces of multiple electrical components placed in the placement sections have substantially a same height.

5. The component supply device of claim 1 , further comprising:

a shuttle device configured to move at least one of the placement sections in the conveyance direction.

6. The component supply device of claim 1 , wherein the placement sections each include a recessed section and the detection device detects if the electrical component is mispositioned in the recessed section in the up-down direction.
