Abstract

The present invention provides a system composed of a monitor unit including a display and being driven by a battery and a base unit for transmitting image information to the monitor unit, which system is capable of charging the battery for driving the monitor unit without the need of provision of any special charging unit The monitor unit has a configuration that a battery is mounted on a back surface portion and a stand is contained in the back surface portion, and also a groove portion is formed in a bottom surface and a charge terminal is provided in the groove portion. The base unit has a configuration that a holding rail is formed in a lower portion of a front surface portion and a charge terminal is provided on the holding rail. In the case of charging the battery, the monitor unit is stood against the front surface portion of the base unit in such a manner that the stand is contained in the stand containing groove portion and the holding rail of the base unit is inserted in the groove portion of the bottom surface of the monitor unit. A rib for pressing the battery onto the battery mounting portion located on one end side of the battery containing groove portion is formed on the back surface of the battery cover.

Claims

1. A monitor unit, in which a display is provided on a front surface portion and a battery is mounted in a back surface portion or another portion, characterized in that

a groove portion, in which a holding rail provided on a bottom portion of a front surface portion of a base unit for transmitting image information to said monitor unit is to be inserted, is formed in a bottom surface of said monitor unit;

and

a charge terminal to be connected to a charge terminal provided on said holding rail of said base unit is provided in said groove portion of said monitor unit.

2. A monitor unit according to claim 1, wherein planes, located at both ends in a direction equivalent to a lateral direction of a screen of said display, of said groove portion are tilted.

3. A monitor unit according to claim 1, wherein a stand for allowing said monitor unit to self-stand is provided on said back surface portion of said monitor unit.

4. A monitor unit according to claim 1, wherein a plurality of antennas, each of which forms a hemispherical surface shaped radiation pattern, are disposed in such a manner that back surface sides of the radiation patterns of said plurality of antennas are opposed to each other;

and

either of said plurality of antennas is selected on the basis of reception level information of said plurality of antennas, to thereby form an antenna having a full-spherical surface shaped radiation pattern as a whole.

5. A base unit for transmitting image information to a monitor unit, said monitor unit including a display provided on a front surface portion and a battery mounted on a back surface portion or another portion, characterized in that

a holding rail to be inserted in a groove portion formed in a bottom surface of said monitor unit is provided on a bottom portion of a front surface portion of said base unit;

and

a charge terminal to be connected to a charge terminal provided in said groove portion of said monitor unit is provided on said holding rail.

6. A base unit according to claim 5, wherein planes, located at both ends in a direction equivalent to a lateral direction of a screen of said display of said monitor unit, of said holding rail are tilted.

7. A base unit according to claim 5, wherein said front surface portion of said base unit is tilted on a rear side.

8. A base unit according to claim 5, wherein a plurality of antennas, each of which forms a hemispherical surface shaped radiation pattern, are disposed in such a manner that back surface sides of the radiation patterns of said plurality of antennas are opposed to each other;

and

either of said plurality of antennas is selected on the basis of reception level information of said plurality of antennas, to thereby form an antenna having a full-spherical surface shaped radiation pattern as a whole.

9. A radio communication system characterized by including:

a monitor unit including a display provided on a front surface portion and a battery mounted on a back surface portion or another portion, wherein a groove portion in which a holding rail provided on a bottom portion of a front surface portion of a base unit for transmitting image information to said monitor unit is formed in a bottom surface of said monitor unit and a charge terminal to be connected to a charge terminal provided on the holding rail of the base unit is provided in said groove portion; and

a base unit for transmitting image information to said monitor unit, wherein a holding rail to be inserted in said groove portion of said monitor unit is provided on a bottom portion of a front surface portion of said base unit, and a charge terminal to be connected to said charge terminal provided in said groove portion of said monitor unit.

10. An information terminal unit including a display on a front surface portion and being driven by a battery, characterized in that

a battery containing groove portion is formed in a back surface portion and a battery mounting portion is provided on one end side of said battery containing groove portion;

a battery cover is provided so as to be mounted in said battery containing groove portion in a state in which a battery has been inserted in said battery containing groove portion from a rear side of said back surface portion, being slid in said battery containing groove portion in a direction parallel to a screen of said display, and mounted in said battery mounting portion; and

a rib for pressing said battery on said battery mounting portion side is formed on a back surface of said battery cover.

11. An information terminal unit according to claim 10, wherein said one end is one end in a lateral direction of a screen of said display.

12. An information terminal unit according to claim 10, wherein a stand containing groove portion is formed around said battery containing groove portion of said back surface portion, and a stand for allowing said information terminal unit to self-stand is contained in said stand containing groove portion.
