Abstract

The electronic equipment according to the present invention is adapted to be operated by an operator in facing positional relationship therewith. This electronic equipment includes a housing accommodating an electronic circuit for operation and a high-frequency circuit for wireless communication related to the operation, and a dielectric antenna connected to the high-frequency circuit. The dielectric antenna is mounted on the rear surface of the housing near a lateral end thereof. Since the electronic circuit for operation and the high-frequency circuit for wireless communication are provided in the housing, it is not necessary to connect a personal computer and a mobile telephone by a cable according to predetermined specifications as in the prior art, so that it is possible to provide electronic equipment which can be easily used as a mobile terminal. Further, since the dielectric antenna connected to the high-frequency circuit is mounted on the rear surface of the housing near a lateral end thereof, the antenna characteristics can be improved and stabilized.

Claims

1. An electronic equipment having a wireless communication function, comprising:

a housing accommodating a circuit for wireless communication and an electronic circuit for operation different from wireless communication, said housing including a body housing and a subhousing adapted to be opened and closed with respect to said body housing; and

a switch which controls the operation of said circuit for wireless communication independently of the operation of said electronic circuit, said switch being provided on said housing at a position which is operable in the closed position of the subhousing.

2. An electronic equipment according to claim 1, further comprising a keyboard provided on said body housing in relation to said operation, and a display provided on said subhousing.

3. An electronic equipment according to claim 1, further comprising an indicator which indicates an electric field strength of electromagnetic waves related to said wireless communication.

4. An electronic equipment according to claim 1, wherein said switch is a slide switch.

5. An electronic equipment according to claim 1, wherein said circuit for wireless communication includes an oscillator;

and said circuit for wireless communication is turned off by turning off the oscillator.

6. An electronic equipment according to claim 1, wherein said electronic equipment further comprises a power supply circuit which supplies an electric power to said circuit for wireless communication, and said circuit for wireless communication is turned off by the operation of said power supply circuit.

7. An electronic equipment according to claim 1, wherein said electronic equipment is a mobile apparatus which is capable of transmitting and receiving an e-mail.
