To solve the problem that it is difficult to determine whether a particular item is stored in a storage box or an action has been taken for the stored item, such as taking a dose of medicine.
From the presence or absence of a stored item and a time interval after the stored item is taken out, whether or not a particular action has been taken for the stored item is determined by a storage detecting means 2 and a time measurement determining means 3. The time interval after the action and the number of actions are displayed or informed of by a display informing means 6. This makes it possible to easily check, even from the outside of the storage box, the presence or absence of the stored item, whether a particular action has been taken for the stored item, whether a dose of medicine has been taken or not, or a time interval from the action.
