Claim 2:
3. A turning control apparatus for controlling driving of a turning body in a working machine that includes the turning body, a support body that supports the turning body turnably, and a turning drive device that turns the turning body, the turning control apparatus comprising:
a target stop position setting unit that sets a target stop position, which is a position at which the turning of the turning body is to be stopped;
a turning command unit that provides an automatic stop command for automatically stopping the turning body at the target stop position to the turning drive device; and
a turning operation member to which a turning operation for turning the turning body is applied, wherein:
the target stop position setting unit includes: an image taking device that is mounted on the working machine and takes an image of the working machine and surroundings thereof; an image processing device that foiins an overhead view image of the working machine and a surrounding object positioned around the working machine based on the image taken by the image taking device; an image display device including a display screen capable of displaying the overhead view image; an image display command unit that makes the display screen display a target stop position setting image including the overhead view image; a setting operation member to which a position setting operation for setting the target stop position based on the position of the image of the working machine and the surrounding object included in the overhead view image is applied; and a target stop position determination unit that determines the target stop position based on the position setting operation,
the turning command unit is configured to provide a turning drive command for making the turning body perform a turning motion corresponding to the turning operation applied to the turning operation member to the turning drive device when the target stop position is not set and configured to provide an automatic stop command for making the turning body perform automatically stopping motion in preference to the turning operation to the turning drive device when the target stop position is set, and
the turning operation member serves as the setting operation member, and the turning control apparatus further comprises a command switching unit switchable between a target stop position setting mode of making the target stop position determination unit deteiniine the target stop position with regarding the operation applied to the turning operation member as the position setting operation and a turning operation mode of making the turning command unit output the turning drive command to the turning command unit with regarding the operation applied to the turning operation member as the turning operation.
