ABSTRACT:
An apparatus for inspecting vessels for the presence of foreign matters inspects the vessel as it undergoes a reverse rotation which follows a forward rotation. A receptacle on which the vessel is driven for rotation is mounted on a rotatable body, and a receptacle is driven by a control motor for rotation in the forward and the reverse direction. A controller which controls the control motor detects any change in the speed of rotation of the rotatable body, and responds to such change by controlling the motor so that a given, predetermined permissible inspecting condition of the vessel is maintained during its forward and reverse rotation in the presence of a change in the speed of rotation of the rotatable body.
