  • the flag of the capsule element in the notification array is set to “FALSE”, and thus the display contents of the second display D 2 are rewritten so as to clear the notification of the insufficient residual amount of the capsule 106 .
  • the value of the battery element in the notification array is set to “TRUE”, and thus the display contents of the second display D 2 are rewritten so as to make a notification of the insufficient residual amount of the battery BAT.
  • FIG. 16 shows Example 2 concerning rewrite of the display contents of the second display D 2 .
  • Example 2 shown in FIG. 16 as an initial state, a state in which the residual amounts of all the elements (the battery BAT, the cartridge 104 , and the capsule 106 ) are sufficient, that is, a state in which the residual amounts of the elements are equal to or larger than the thresholds, respectively, is shown.
  • the values in the notification array for all the elements are set to “FALSE”, and nothing is displayed on the second display D 2 .
  • both the values of the battery element and the capsule element in the notification array are set to “TRUE”.
  • one of the battery BAT and the capsule 106 is selected as the target element.
  • the condition (condition example 1 of FIG. 14 ) concerning the recovery time of the residual amount is adopted, the battery BAT is selected as the target element, and the display contents of the second display D 2 are rewritten so as to make a notification of the insufficient residual amount of the battery BAT.
  • the value of the battery element in the notification array is set to “FALSE”, and thus the display contents of the second display D 2 are rewritten so as to clear the notification of the insufficient residual amount of the battery BAT and make a notification of the insufficient residual amount of the capsule 106 .
  • the value of the capsule element in the notification array is set to “FALSE”, and thus the display contents of the second display D 2 are rewritten so as to clear the notification of the insufficient residual amount of the capsule 106 .
