Electronic device and function assigning method

Abstract

At step ST 2 , an assign key changing item is selected from menu items. At step ST 3 , an assign key to which a function is assigned is selected. At step ST 4 , a function to be assigned is selected. The selected function is assigned to the selected assign key. At step ST 5 , a setting result indication screen appears. When one of two paired functions is assigned, a message which prompts a user to assign the other function. After the message has appeared for a predetermined time, the latest assigned states appear. At step ST 6 , the latest assign key information is stored to a non-volatile memory. To quit an assigning process, a menu button 8 is pressed and the menu is closed (at step ST 8 ).

1 . An electronic device having a display panel and a plurality of keys to which desired functions can be assigned, comprising: 
 displaying a plurality of items on the display panel;    setting a desired item which is selected from the plurality of items;    displaying a setting screen corresponding to the desired item which is selected; and    setting the desired item by using the setting screen,    wherein a function for displaying the setting screen when one of the keys is operated is assigned to at least one of the plurality of keys.    
   
   
       2 . The electronic device as set forth in  claim 1 , 
 wherein when one of two paired functions is assigned to one of the plurality of keys, a message which prompts a user to assign the other of the two paired functions to the key appears.    
   
   
       3 . The electronic device as set forth in  claim 1 , 
 wherein when one of two paired functions is assigned to one of the plurality of keys, the other of the paired functions is automatically assigned to the key.    
   
   
       4 . The electronic device as set forth in  claim 1 , 
 wherein a sequence of operations that a user has preformed are stored and stored operations are assigned to one of the plurality of keys.    
   
   
       5 . The electronic device as set forth in  claim 1 , 
 wherein functions assigned to two keys of the plurality of keys are changed with each other.    
   
   
       6 . An electronic device having a display panel and a plurality of keys to which desired functions can be assigned, comprising: 
 displaying a plurality of items on the display panel;    setting a desired item which is selected from the plurality of items;    displaying a setting screen corresponding to the desired item which is selected; and    setting the desired item by using the setting screen,    wherein a function for displaying the setting screen for items that are not included in the plurality of items when one of the keys is operated is assigned to at least one of the plurality of keys.    
   
   
       7 . The electronic device as set forth in  claim 6 , 
 wherein when one of two paired functions is assigned to one of the plurality of keys, a message which prompts a user to assign the other of the two paired functions to the key appears.    
   
   
       8 . The electronic device as set forth in  claim 6 , 
 wherein when one of two paired functions is assigned to one of the plurality of keys, the other of the paired functions is automatically assigned to the key.    
   
   
       9 . The electronic device as set forth in  claim 6 , 
 wherein a sequence of operations that a user has preformed are stored and stored operations are assigned to one of the plurality of keys.    
   
   
       10 . The electronic device as set forth in  claim 6 , 
 wherein functions assigned to two keys of the plurality of keys are changed with each other.    
   
   
       11 . A method of assigning desired functions to a plurality of keys, comprising the steps of: 
 displaying a plurality of items and selecting a desired item from the plurality of items; and    selecting a key to which a function is assigned from the plurality of keys,    wherein a function which has been selected at the function selecting step and which can be set on a menu is assigned to the key selected at the key selecting step.    
   
   
       12 . A method of assigning desired functions to a plurality of keys, comprising the steps of: 
 displaying a plurality of items and selecting a desired item from the plurality of items; and    selecting a key to which a function is assigned from the plurality of keys,    wherein a function which has been selected at the function selecting step and which is other than functions which can be set on a menu is assigned to the key selected at the key selecting step.
