Control device and printing apparatus

Abstract

A control device includes a prohibition unit that prohibits use of an electronic apparatus in a case where a sum of a cumulative amount of use of the electronic apparatus for a predetermined period of time and a new amount of use which is newly instructed by an user exceeds a permitted amount in the period of time which is permitted for the user, and a permission unit that permits use of the electronic apparatus by an amount based on an unused amount which is a difference between the permitted amount and the cumulative amount of use in an unreaching period when the unreaching period is present before the period of time in an accounting period including the period of time, in a case where the use of the electronic apparatus is prohibited by the prohibition unit.

What is claimed is: 
     
         1 . A control device comprising:
 a prohibition unit that prohibits use of an electronic apparatus performed by a user in a case where a sum of a cumulative amount of use of the electronic apparatus performed by the user for a predetermined period of time and a new amount of use which is newly instructed by the user exceeds a permitted amount in the predetermined period of time which is permitted for the user; and   a permission unit that permits use of the electronic apparatus by an amount based on an unused amount in a period before the predetermined period of time in a case where the user's use of the electronic apparatus is prohibited by the prohibition unit.   
     
     
         2 . The control device according to  claim 1 , wherein, in a case where the user's use of the electronic apparatus is prohibited by the prohibition unit and an unreaching period is present before the predetermined period of time in an accounting period including the predetermined period of time, the permission unit permits the use of the electronic apparatus by an amount based on the unused amount which is a difference between a permitted amount and a cumulative amount of use in the unreaching period for which the cumulative amount of use does not reach the permitted amount. 
     
     
         3 . The control device according to  claim 2 , further comprising:
 a notification unit that gives notice that the cumulative amount of use of the electronic apparatus for the predetermined period of time exceeds the permitted amount in the predetermined period of time in a case where the use of the electronic apparatus is permitted by the permission unit.   
     
     
         4 . The control device according to  claim 2 , wherein the permission unit permits the use of the electronic apparatus by an amount based on the unused amount in all of the unreaching periods before the predetermined period of time in the accounting period including the predetermined period of time, in a case where the users use of the electronic apparatus is prohibited by the prohibition unit. 
     
     
         5 . The control device according to  claim 2 , wherein the permission unit permits the use of the electronic apparatus by an amount based on an unused amount in the unreaching period immediately before the predetermined period of time in the accounting period including the predetermined period of time, in a case where the users use of the electronic apparatus is prohibited by the prohibition unit. 
     
     
         6 . The control device according to  claim 2 , wherein the permission unit permits the use of electronic apparatus by an amount obtained by multiplying a coefficient less than 1 by the unused amount.
