Abstract

Apparatus for controlling and recording the use of a plurality of photocopiers are disclosed. The apparatus includes a terminal associated with each of the photocopiers and a central recorder connected to each of the terminals. Each authorized user of the photocopiers is issued a badge having user identification information encoded thereon. The information on the badge is read at the terminal and transmitted to the central recorder before the copier is used while counts made at the terminal and representing the copies made are transmitted to the central recorder after the user has completed making his copies. A communication link between an individual terminal and the central recorder is only required immediately prior to and following the use of the copier by each user.

Claims

1. Apparatus for monitoring the use of a plurality of controlled devices comprising a plurality of terminals and a central recorder, one terminal being associated with each of said devices and each of said terminals comprising:

first means for receiving and removing user identification information;

second means for establishing a communication link between the terminal and said central recorder when user identification information is received by said first means and when user identification is removed from said first means;

third means coupled to the associated device for counting the uses of said device;

fourth means coupled to said first, second, and third means for transmitting said user identification information to said central recorder when user identification information is received by said first means and transmitting said use count to said central recorder when said user identification information is removed from said first means; and

fifth means coupled to said second means for terminating the communication link between said terminal and said central recorder at the conclusion of the transmission of said user identification information to said central recorder and at the conclusion of the transmission of said use count to said central recorder.

3. The apparatus of claim 1 wherein said central recorder comprises apparatus for recording said user identification information and said use count.

2. Apparatus for monitoring the use of a plurality of controlled devices comprising a plurality of terminals and a central recorder, one terminal being associated with each of said devices and each of said terminals comprising:

first means for receiving a badge bearing user identification information and reading said information;

second means for establishing a communication link between the terminal and said central recorder when a badge is received by said first means and when a badge is removed from said first means;

third means coupled to the associated device for counting the uses of said device;

fourth means coupled to said first, second, and third means for transmitting said user identification information to said central recorder when a badge is received by said first means and transmitting said use count to said central recorder when a badge is removed from said first means; and

fifth means coupled to said second means for terminating the communication link between said terminal and said central recorder at the conclusion of the transmission of said user identification information to said central recorder and at the conclusion of the transmission of said use count to said central recorder.

4. Apparatus for monitoring the use of a plurality of controlled devices comprising a plurality of terminals and a central recorder, one terminal being associated with each of said devices and each of said terminals comprising:

first means for receiving a badge bearing user identification information;

second means for establishing a communication link between the terminal and said central recorder when a badge is received by said first means and when a badge is removed from said first means;

third means coupled to said second means and the associated device for enabling the operation of said associated device in response to a first signal from said central recorder and disabling the operation of said associated device in response to the removal of a badge from said first means;

fourth means coupled to said first and second means for transmitting said user identification information to said central recorder when a badge is received by said first means and transmitting said use count to said central recorder when a badge is removed from said first means; and

fifth means coupled to said second means for terminating the communication link between said terminal and said central recorder at the conclusion of the transmission of said user identification information to said central recorder and at the conclusion of the transmission of said use count to said central recorder;

and said central recorder comprising;

sixth means for verifying the validity of the user identification information received from said terminal; and

seventh means coupled to said sixth means for transmitting said first signal to a terminal in response to the receipt of valid user identification information.

5. Apparatus for monitoring the use of a plurality of controlled devices comprising a plurality of terminals and a central recorder, one terminal being associated with each of said devices and each of said terminals comprising:

first means for receiving a badge bearing user identification information and reading said information;

second means coupled to said first means and establishing a communication link between the terminal and said central recorder when a badge is received by said first means and when a badge is removed from said first means;

third means coupled to said second means for receiving inquiry number signals from said central recorder in response to the establishment of a communication link with said central recorder and transmitting response number signals to said central recorder; and

fourth means coupled to said second and third means for terminating the communication link between said terminal and said central recorder at the conclusion of the transmission of said response numbers to said central recorder.

6. The apparatus of claim 5 wherein said third means is further coupled to said first means and said response number signals represent said user identification information when a badge is received by said first means and said response number signals represent said use count when a badge is removed from said first means.

7. The apparatus of claim 6 wherein one of said response number signals further represents whether a badge is received in said first means.

8. The apparatus of claim 7 wherein said central recorder includes fifth means for recording the responses represented by at least one of said response number signals.

9. The apparatus of claim 8 wherein said central recorder further comprises sixth means for verifying the validity of the user identification information and seventh means coupled to sixth means for enabling the operation of said sixth means only when said one of said response number signals indicates that a badge is received within said first means.

10. The apparatus of claim 9 wherein said terminal further comprises eighth means coupled to said second means and the associated device for enabling the operation of said associated device in response to a first inquiry number signal from said central recorder and said central recorder further comprises ninth means coupled to said sixth means for transmitting said first inquiry number signal to a terminal in response to valid user identification information.

11. The apparatus of claim 10 wherein said associated devices are copying machines.
