Claim 0:
1. 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, the height information stored in a management device and based on mounting schedule information of the board, and
set a reference position separated from a top surface of the board by a distance corresponding to heights of the components, acquired from the height information, 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
the setting section uses a method of setting the reference position with a most frequent value of the heights of the respective components as the distance,
in a case where there are multiple most frequent values when using the method of setting the reference position by using the most frequent value as the predetermined setting method, the setting section sets multiple reference positions by using each of the multiple most frequent values, and
the control section controls the lifting/lowering mechanism and the camera such that the inspection image is captured at each of the multiple reference positions.
