Abstract

An information output apparatus comprises a body and a base station. The body has a first battery and an output unit. The first battery is a rechargeable battery. The output unit outputs information. The base station is fixed to a car and supports the body that is detachable. The base station has a power generator that converts at least one of light, heat, wind, or vibration to electrical energy. Charging the first battery is performed on the basis of electrical energy generated by the power generator, without using electrical energy charged in a car battery. The body operates on the basis of electrical energy that is either generated by the power generator or charged in the first battery, without using the electrical energy charged in the car battery.

Claims

1. An information output apparatus comprising:

a body that has a first battery and an output unit, said first battery being a rechargeable battery, said output unit outputting information;

a base station that is fixed to a car and supports said body that is detachable;

a first detector that detects the ON/OFF state of an accessory power supply of said car to which said base station is mounted; and

a transmitter that wirelessly transmits detection results of said first detector as a first information;

said base station having a power generator that converts at least one of light, heat, wind, or vibration to electrical energy, and being a cradle for said body;

charging said first battery being performed on the basis of electrical energy generated by said power generator, without using electrical energy charged in a car battery;

said body operating on the basis of electrical energy that is either generated by said power generator or charged in said first battery, without using the electrical energy charged in said car battery;

wherein at least one of said base station or said body has a receiver that receives said first information from said transmitter;

said body has a controller that controls the ON/OFF state of said body on the basis of said first information.

2. The information output apparatus according to claim 1, wherein said first detector is attached to a cigarette lighter socket of said car, said first detector detects whether electrical power is supplied to said cigarette lighter socket as the ON/OFF state of said accessory power supply.

3. The information output apparatus according to claim 1, wherein said first detector detects a vehicle speed signal from an ECU of said car;

and

said transmitter sends information regarding the ON/OFF state of said accessory power supply and information regarding vehicle speed from said vehicle speed signal, as said first information.

4. The information output apparatus according to claim 1, wherein said base station has a battery that is a rechargeable battery;

charging said battery that said base station has is performed on the basis of electrical energy generated by said power generator;

said body operates on the basis of electrical energy that is either generated by said power generator, charged in said first battery, or charged in said battery that said base station has;

wherein electrical energy generated by said power generator is preferentially used for driving said body and for charging said first battery when said body is connected to said base station through said cradle.

5. The information output apparatus according to claim 4, wherein said power generator converts at least one of light or heat to electrical energy;

said base station operates on the basis of electrical energy generated by said power generator and has a cooler that cools down said battery that said base station has.

6. The information output apparatus according to claim 1, wherein said base station has an ascertaining device that ascertains a state of connection between said body and said base station;

electrical power is supplied from said base station to said body by magnetic coupling after the state of connection is ascertained by said ascertaining device.

7. The information output apparatus according to claim 1, wherein at least one of said base station or said body has a detector that detects information regarding vibration of said car to which said base station is mounted;

said body has a controller that controls the ON/OFF state of said body on the basis of said vibration information.

8. A base station of an information output apparatus comprising:

a power generator that converts at least one of light, heat, wind or vibration to electrical energy;

said base station being fixed to a car, supporting a body that is detachable, and being a cradle for said body;

said body having a first battery and an output unit, said first battery being a rechargeable battery, said output unit outputting information;

charging said first battery being performed on the basis of electrical energy generated by said power generator, without using electrical energy charged in a car battery;

said body operating on the basis of electrical energy generated by said power generator or charged in said first battery, without using the electrical energy charged in said car battery;

wherein at least one of said base station or said body has a receiver that receives a first information from a transmitter;

said transmitter wirelessly transmits detection results of a first detector as said first information;

said first detector detects the ON/OFF state of an accessory power supply of said car to which said base station is mounted; and

said body has a controller that controls the ON/OFF state of said body on the basis of said first information.

9. An information output apparatus comprising:

a body that has a first battery and an output unit, said first battery being a rechargeable battery, said output unit outputting information; and

a base station that is fixed to a car and supports said body that is detachable;

said base station having a power generator that converts at least one of light, heat, wind, or vibration to electrical energy, and being a cradle for said body;

charging said first battery being performed on the basis of electrical energy generated by said power generator, without using electrical energy charged in a car battery;

said body operating on the basis of electrical energy that is either generated by said power generator or charged in said first battery, without using the electrical energy charged in said car battery;

wherein one of said body or said base station has a concave portion;
