         10 . The ice making device of  claim 2 ,
 wherein the controller is configured to control the liquid supplier so that a liquid supply time of the one tray is less than a liquid supply time of the other tray.   
     
     
         11 . The ice making device of  claim 2 ,
 wherein the controller is configured to control the liquid supplier so that a number of times of a liquid supply to the one tray is less than a number of times of a liquid supply to the other tray.   
     
     
         12 . The ice making device of  claim 2 ,
 wherein the controller is configured to control the cooler so that a timing of a supply of a cooling power to the one tray is delayed from a timing of a supply of a cooling power to the other tray.   
     
     
         13 . The ice making device of  claim 12 ,
 wherein the controller is configured to control the cooler so that a supply of a cooling power to the one tray starts when a first reference time elapses after the supply of the cooling power to the other tray starts.   
     
     
         14 . The ice making device of  claim 13 ,
 wherein the controller is configured to control the cooler so that the supply of the cooling power to the one tray and the other tray stops when a second reference time elapses after the supply of the cooling power to the one tray starts.   
     
     
         15 . The ice making device of  claim 2 ,
 wherein the controller is configured to control the cooler so that a supply amount of a cooling power per unit time to the one tray is less than a supply amount of a cooling power per unit time to the other tray.   
     
     
         16 . The ice making device of  claim 2 ,
