Abstract
A control device includes: a prohibition unit that prohibits a user from using an electronic apparatus in a case where a sum of a cumulative usage amount of the electronic apparatus by the user for a predetermined period and a new usage amount which is newly instructed by the user exceeds a permitted amount for the user in the period; a subtraction unit that, in a case where the user instructs the electronic apparatus to be continuously used after the use of the electronic apparatus is prohibited by the prohibition unit, subtracts from permitted amounts for the user for a plurality of periods later than the period; and a permission unit that permits the user to use the electronic apparatus after the subtraction is performed by the subtraction unit.
