Abstract

The switch device includes a control switch that turns on/off an electrical connection between an apparatus and the power supply, a condition judging circuit that judges conditions of driving the control switch, an electric wave reception circuit that receives an electric wave, and a power supply circuit that generates power from the electric wave received by the electric wave reception circuit. An electric wave transmission device that transmits an electric wave for making the switch device operate is arranged in a space, whereby the electric wave can be received by the electric wave reception device in the specific space. The switch device controls the control switch to be turned off/on when the electric wave is received. Alternatively, when the electric wave is not received, the switch device turns on/off the control switch.

First claim

1 . (canceled)

2 . An electronic apparatus comprising:
a signal reception circuit; a condition judging circuit functionally connected to an output of the signal reception circuit; and a control circuit functionally connected to an output of the condition judging circuit, wherein the control circuit is configured to disable a function of the electronic apparatus when the condition judging circuit outputs a control signal depending on a signal received by the signal reception circuit, and wherein the electronic apparatus is configured so that a user can enable the function of the electronic apparatus only when the signal is not received by the signal reception circuit.

3 . The electronic apparatus according to claim 2 ,
wherein the signal reception circuit, the condition judging circuit, and the control circuit are part of a switch device mounted in the electronic apparatus.

4 . The electronic apparatus according to claim 2 ,
wherein the electronic apparatus is configured to automatically disable the function of the electronic apparatus upon reception of the signal.

5 . The electronic apparatus according to claim 2 ,
wherein the electronic apparatus is configured to disable the function of the electronic apparatus upon reception of the signal, regardless of an intent of the user of the electronic apparatus.

6 . The electronic apparatus according to claim 2 ,
wherein the electronic apparatus is configured to automatically disable a ring alert of the electronic apparatus upon reception of the signal.

7 . The electronic apparatus according to claim 2 , further comprising a power supply circuit connected between the signal reception circuit and the condition judging circuit, and configured to generate power from the signal,
wherein the signal reception circuit is an electric wave reception circuit, and wherein the condition judging circuit is configured to output the control signal upon detection of power generated by the power supply circuit.

8 . An electronic apparatus comprising:
a signal reception circuit; a condition judging circuit functionally connected to an output of the signal reception circuit; and a control circuit functionally connected to an output of the condition judging circuit, wherein the control circuit is configured to change a mode of the electronic apparatus when the condition judging circuit outputs a control signal depending on a signal received by the signal reception circuit, and wherein the electronic apparatus is configured so that a user can change the mode of the electronic apparatus only when the signal is not received by the signal reception circuit.

9 . The electronic apparatus according to claim 8 ,
wherein the signal reception circuit, the condition judging circuit, and the control circuit are part of a switch device mounted in the electronic apparatus.

10 . The electronic apparatus according to claim 8 ,
wherein the electronic apparatus is configured to automatically change the mode of the electronic apparatus upon reception of the signal.

11 . The electronic apparatus according to claim 8 ,
wherein the electronic apparatus is configured to change the mode of the electronic apparatus upon reception of the signal, regardless of an intent of the user of the electronic apparatus.

12 . The electronic apparatus according to claim 8 ,
wherein the electronic apparatus is configured to automatically set the mode of the electronic apparatus to a silent mode upon reception of the signal.

13 . The electronic apparatus according to claim 8 , further comprising a power supply circuit connected between the signal reception circuit and the condition judging circuit, and configured to generate power from the signal,
wherein the signal reception circuit is an electric wave reception circuit, and wherein the condition judging circuit is configured to output the control signal upon detection of power generated by the power supply circuit.

14 . An electronic apparatus comprising:
a signal reception circuit; a condition judging circuit functionally connected to an output of the signal reception circuit; a control switch functionally connected to an output of the condition judging circuit; and a circuit functionally connected to the control switch, wherein the control switch is configured to cut supply of power to the circuit when the condition judging circuit outputs a control signal depending on a signal received by the signal reception circuit, and wherein the electronic apparatus is configured so that a user can control supply of power to the circuit only when the signal is not received by the signal reception circuit.

15 . The electronic apparatus according to claim 14 ,
wherein the signal reception circuit, the condition judging circuit, and the control switch are part of a switch device mounted in the electronic apparatus.

16 . The electronic apparatus according to claim 14 ,
wherein the electronic apparatus is configured to automatically cut supply of power to the circuit upon reception of the signal.

17 . The electronic apparatus according to claim 14 ,
wherein the electronic apparatus is configured to cut supply of power to the circuit upon reception of the signal, regardless of an intent of the user of the electronic apparatus.

18 . The electronic apparatus according to claim 14 , further comprising a second switch and a power supply,
wherein the second switch and the control switch are connected in series between the power supply and the circuit, and wherein the second switch is controllable by the user.

19 . The electronic apparatus according to claim 14 , further comprising a power supply circuit connected between the signal reception circuit and the condition judging circuit, and configured to generate power from the signal,
