Abstract

An appliance management system includes an electronic device having some functions useful to a user, and an appliance management device designed to be always carried by the user. The electronic device receives a predetermined signal from the appliance management device, and extracts an ID code of the appliance management device. The electronic device becomes unusable when the signal receiving condition is bad. The functions of the electronic device are restricted according to the result of collation between management information registered in the electronic device and the ID code in the received signal.

collation means for collating the discrimination code extracted by the extraction means (hereinafter referred to as “

received code”

) with the registered code; and

restriction means for restricting the processing executed by the processing means if there is no match between the registered code and the received code as a result of the collation by the collation means.

3. An electronic device according to

claim 2

, wherein the management information is formed in such a manner that the registered code and the contents of a restriction with respect to the registered code are related to each other, and the restriction means restricts the processing executed by the processing means according to the contents of the management information if there is a match between any registered code and the received code as a result of the collation by the collation means.

4. An electronic device according to

claim 3

, further comprising registration means for accepting registration of a code entered as the discrimination code by a user, and for registering the entered discrimination code in the management information.

6. An electronic device according to 2, wherein the processing means is arranged so as to be able to execute at least one of the processing of data and/or a signal, and processing for transmitting a wireless signal.

9. An electronic device management system comprising:

an electronic device according to

claim 2

; and

a user identification assisting device according to claim.

7. A user identification assisting device comprising:

a discrimination code memory means having a predetermined discrimination code stored therein in advance;

transmitting means for transmitting a signal containing the discrimination code; and

wearing means for enabling the user identification assisting device to be worn about the body or on a garment of a user.

10. An appliance management device for managing an electronic device, the appliance management device comprising:

inquiry means for inquiring of the electronic device about the presence/absence of the electronic device;

response detection means for detecting a response from the electronic device to the inquiry;

determination means for making a determination as to whether the electronic device is out of a control zone of the appliance management device on the basis of a result of detection performed by the response detection means; and

notifying means for issuing information that the electronic device is out of the control zone if the determination means determines that electronic device is out of the control zone.

11. An appliance management device according to

claim 10

, wherein the inquiry means includes:

a management device code holding means for holding in advance a discrimination code unique to the appliance management device (hereinafter referred to as “

management device code”

); and

transmitting means for transmitting the management device code.

12. An appliance management device according to

claim 11

, wherein the transmitting means transmits the management device code at predetermined time intervals.

13. An appliance management device according to

claim 10

, wherein the determination means determines that the electronic device is out of the control zone if the response detection means does not detect the response in a predetermined time period after the transmission of the management device code performed by the transmitting means.

14. An appliance management device according to

claim 13

, further comprising appliance code memory means for storing registered information containing a discrimination code unique to at least one electronic device to be managed (hereinafter referred to as “
