         12 . The apparatus according to  claim 8 , further comprising:
 an image sensor that captures image data of the object;   a detector that detects at least one of an upper position and a lower position of the object from the image data; and   a controller that drives the holding unit to move toward the upper position when the upper position is detected, and drives the conveyor to move toward the lower position when the upper position is detected.   
     
     
         13 . The apparatus according to  claim 12 , wherein
 the image sensor obtains positional information including information regarding the distance from the object, and   the controller computes at least one of a first distance between the holding unit and the upper position and a second distance between the conveyor and the lower position based on the positional information, drives the holding unit according to the first distance when the first distance is computed, and drives the conveyor according to the second distance when the second distance is computed.   
     
     
         14 . The apparatus according to  claim 8 , wherein the holding unit moves so as to not strike the conveyor and the object when the conveyor conveys the object. 
     
     
         15 . The apparatus according to  claim 12 , wherein when the object is loaded on an intermediate shelf, the controller moves the conveyor so that one end of the conveyor is placed at the lower position of the object, or that one end of the conveyor is positioned at a lower end of the intermediate shelf close to the conveyor. 
     
     
         16 . The apparatus according to  claim 8 , further comprising a bench that is a destination of the object. 
     
     
         17 . A cargo handling apparatus, comprising:
 a conveyor that conveys an object; and   a holding unit that holds the object by suction at at least two places and loads the object to the conveyor;   wherein:
 the conveyor moves close to the object; 
 the holding unit loads the object to the conveyor closing to the object; and 
 the conveyor moves to a bench and conveys the object to the bench. 
   
     
     
         18 . A cargo handling method for a cargo handling apparatus, comprising:
 moving a conveyor close to an object; and   holding the object by suction at at least two places and loading the object to the conveyor so as to not strike the object when the conveyor conveys the object   
     
     
         19 . A controlling apparatus, comprising a controller configured to:
 control a conveyor connected to a base so as to move the conveyor close to an object;   control a holding unit connected to the base so as to hold the object by suction at at least two places and load the object to the conveyor;   control the conveyor so as to move close to a bench and convey the object to the bench.   
     
     
         20 . The apparatus according to  claim 19 , wherein the controller:
 detects at least one of an upper position and a lower position of the object from a positional information of the object; and   drives the holding unit to move toward the upper position when the upper position is detected, and drives the conveyor to move toward the lower position when the lower position is detected.   
     
     
         21 . The apparatus according to  claim 20 , wherein
 the positional information includes information regarding the distance from the object, and   the controller:
 computes at least one of a first distance between the holding unit and the upper position and a second distance between the conveyor and the lower position based on the positional information; 
 drives the holding unit according to the first distance when the first distance is computed; and 
 drives the conveyor according to the second distance when the second distance is computed. 
   
     
     
         22 . The apparatus according to  claim 19 , wherein the controller controls the holding unit so as to move without striking the conveyor and the object when the conveyor conveys the object. 
     
     
         23 . The apparatus according to  claim 19 , wherein when the object is loaded on an intermediate shelf, the controller moves the conveyor so that one end of the conveyor is placed at the lower position of the object, or that one end of the conveyor is positioned at a lower end of the intermediate shelf close to the conveyor. 
     
     
         24 . The apparatus according to  claim 19 , wherein the at least two places are at least two surfaces of the object.
