Claim 3:
4. An inspection device that performs inspection by using an inspection image of a board on which multiple components are disposed, the inspection device comprising:
a fixed focus type camera;
a lifting/lowering mechanism configured to move the camera up or down relative to the board;
a setting section configured to acquire height information of the multiple components, and set a reference position separated from a top surface of the board by a distance corresponding to a height of each of the components according to a predetermined setting method such that an imaging surface of each component within an imaging range of the camera is included in a depth of field of the camera; and
a control section configured to control the lifting/lowering mechanism and the camera such that the inspection image is captured after the camera is relatively moved up or down to focus on the reference position, wherein in a case where some of the multiple components scheduled to be disposed on the board is not disposed after height information of the multiple components scheduled to be disposed on the board is acquired and the reference position is set in advance, the setting section resets the reference position in accordance with heights of other components except for some components.
