Guide element for paper alignment

Abstract

An image scanning apparatus includes an image sensor to scan a manuscript, a transfer apparatus to pick up the manuscript and move the manuscript to a manuscript transfer path, and a loading apparatus to load the manuscript scanned by the image sensor. The loading apparatus includes a discharge tray to hold a discharged manuscript and a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript.

         16 . An image scanning apparatus, comprising:
 a loading apparatus to load a manuscript scanned by the image scanning apparatus, the loading apparatus comprising:
 a discharge tray to hold the manuscript, and 
 a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript; and 
   a processor to set the angle of the guide member based on the type of the manuscript.   
     
     
         17 . The image scanning apparatus as claimed in  claim 16 , wherein the processor to set the angle of the guide member at a time of initial operation of a scan job based on the type of manuscript and to reset the angle of the guide member to a predetermined angle at the completion of the scan job. 
     
     
         18 . The image scanning apparatus as claimed in  claim 16 , wherein the processor is to, based on a thickness of the manuscript being thinner than a predetermined thickness, set the angle of the guide member to not allow the guide member to contact the manuscript. 
     
     
         19 . The image scanning apparatus as claimed in  claim 16 , further including:
 a driving member to rotate the guide member,   wherein the processor is to control the driving member to position the guide member at the set angle.   
     
     
         20 . The image scanning apparatus as claimed in  claim 16 , further including:
 a manuscript sensor to sense a thickness of the manuscript,   wherein the processor is to identify the type of the manuscript based on the sensed thickness of the manuscript.   
     
     
         21 . The image scanning apparatus as claimed in  claim 16 , further including:
 an input apparatus to receive information about the type of the manuscript,   wherein the processor is to identify the type of the manuscript based on the received information and set the angle of the guide member based on the type of the manuscript.   
     
     
         22 . The image scanning apparatus as claimed in  claim 19 , wherein the guide member is positioned at a predetermined initial position at an initial operation, wherein the processor is to:
 control the driving member to move from the initial position to the set angle; and   based on a scan job being completed, control the driving member to allow the guide member positioned at the set angle to return to the initial position.   
     
     
         23 . The image scanning apparatus as claimed in  claim 22 , further including:
 a guide member sensor to identify whether the guide member is positioned at the initial position,   wherein the processor is to identify whether the guide member is positioned at the initial position based on a signal sensed in the guide member sensor.   
     
     
         24 . An image scanning apparatus, comprising:
 a loading apparatus to load a manuscript scanned by the image scanning apparatus, the loading apparatus comprising:
 a discharge tray to hold the manuscript, and 
 a guide member to have one end rotatably disposed on the manuscript above an upper part of the discharge tray at an angle formed relative to the discharge tray based on a type of the manuscript; and 
   a display to display an operation manual of the guide member corresponding to the type of the manuscript.   
     
     
         25 . The image scanning apparatus as claimed in  claim 16 , wherein the loading apparatus further includes an inclination member,
 wherein the inclination member is formed on the discharge tray to upwardly extend to incline relative to the discharge tray, and to provide a frictional force to a rear of the manuscript to align the manuscript.   
     
     
         26 . The image scanning apparatus as claimed in  claim 25 , wherein the guide member includes an inclination surface which is formed to not allow a front end of the manuscript to roll with the guide member in an other end inclined toward the discharge tray. 
     
     
         27 . The image scanning apparatus as claimed in  claim 26 , wherein the inclination surface of the guide member is inclined to correspond to an inclination of the inclination member. 
     
     
         28 . An image scanning method, the method comprising:
 by an image scanning apparatus:
 picking up a manuscript and transferring the manuscript to a manuscript transfer path; 
 rotating a guide member of the loading apparatus toward a discharge tray of the loading apparatus to set, by a processor of the image scanning apparatus, an angle corresponding to a type of the manuscript; 
 scanning the manuscript on the manuscript transfer path; and 
 stacking the scanned manuscript on the discharge tray. 
   
     
     
         29 . The image scanning method as claimed in  claim 28 , wherein the rotating the guide member includes identifying the type of the manuscript based on a thickness of the manuscript. 
     
     
         30 . The image scanning method as claimed in  claim 29 , wherein the setting the angle of the guide member includes setting the angle of the guide member to not allow the guide member to be in contact with the manuscript based on the thickness of the manuscript being thinner than a predetermined thickness.
