Processing apparatus

A processing apparatus, comprising:

• a processing tool that includes a drive mechanism, a processing member that is vertically movable to a processing-target member and rotatable relative to the processing-target member by utilizing a driving force of the drive mechanism, and a holder that detachably holds the processing member through a restricting portion;
• a moving mechanism that includes an arm to which the processing tool is attached, and that can freely move the processing tool to the processing-target member by moving the arm;
• and
• a replacement device that can freely replace the processing member, wherein the replacement device comprises,
• a gripping device that includes a single first support member, the single first support member being immovably fixed relative to a floor, a first gripping portion that is immovably fixed relative to the floor and is provided on the first support member, and can freely grip the holder so as to prevent rotation of the holder in a loosening direction when the processing member is removed from the holder, and a second gripping portion that is immovably fixed relative to the floor and is provided on the first support member apart from the first gripping portion, and can freely grip the holder so as to prevent rotation of the holder in a fastening direction when the processing member is attached to the holder, the fastening direction being opposite to the loosening direction;
• and
• a holding device that includes a single movable second support member, a plurality of first holding portions that are provided on the second support member, and can freely and respectively accommodate the processing member removed from the holder, and a plurality of second holding portions that are provided on the second support member apart from the plurality of first holding portions, and can freely and respectively accommodate the processing member to be attached to the holder,
• wherein when the processing member is detached from the holder during replacement of the processing member, the second support member of the holding device is moved relative to the gripping device, thereby positioning the first support member of the gripping device to extend across both a corresponding one of the plurality of first holding portions and a corresponding one of the plurality of second holding portions, arranging the corresponding one of the plurality of first holding portions vertically below the first gripping portion, and arranging the corresponding one of the plurality of second holding portions vertically below the second gripping portion.
