Abstract

A portable type mobile radio telephone wherein a battery holding device and a handset cradle is formed on one wider surface of the flat-shaped transceiver unit to be in parallel to each other. The transceiver unit has a guide hole and a first connector at a narrower surface thereof, and a base plate is attached to the battery holding device and the cradle so as to be interposed between the battery holding device and the transceiver unit, and the base plate has a curved portion at one end portion thereof such that the curved portion faces one narrower surface of the transceiver unit. The curved portion is provided with a guide pin and a second connector so that the first and second connectors are guided by connection of the guide pin and the guide hole and coupled with each other when the base plate is moved in a parallel direction with respect to the wider surface of the transceiver unit. The transceiver unit has an engaging projection on the wider surface thereof and the base plate has an engaging hole which is positioned to face the engaging projection when the first and second connectors are coupled with each other. The transceiver unit and the base plate are connected to each other by engagement of the engaging hole and the engaging projection.

Claims

1. A portable type mobile radio telephone comprising:

a transceiver unit with a flat configuration;

battery holding means for holding a battery which is placed on one wider surface of said transceiver unit;

a cradle for holding a handset, said cradle formed on the one wider surface of said transceiver unit in parallel to said battery holding means, said cradle having engaging means engaged with said handset, and the upper surface of said handset being substantially equal in height to the upper surface of said battery holding means when said handset is engaged with said cradle; and

a rack frame which is integrally formed with said battery holding means.

2. A portable type mobile radio telephone comprising:

a transceiver unit with a flat configuration;

battery holding means for holding a battery which is placed on one wider surface of said transceiver unit; and

a cradle for holding a handset which is formed on the one wider surface of said transceiver unit to be in parallel to said battery holding means, said cradle having engaging means engaged with said handset;

said cradle mounted on a mounting rack which is integrally formed with said battery holding means.

3. A portable type mobile radio telephone as claimed in claim 3, further comprising:

projection means arranged to be mounted on a wall; and

a mounting plate attached to said transceiver unit, said mounting plate having at least one pair of holes, each of said pair of holes being arranged to be engaged with said projection means so that said mobile radio telephone is supported by said pair of holes.

4. A portable type mobile radio telephone as claimed in claim 3, wherein each of said pair of holes comprising a larger diameter portion, a first groove portion coupled to said larger diameter portion and a second groove portion coupled to said first groove portion and extending at substantially right angles to said first groove portion, said projection means having a shaft portion and an engaging portion with a diameter greater than that of said shaft portion, said engaging portion being mounted on one end of said shaft portion, the diameter of said engaging portion being smaller than a diameter of said larger diameter portion of said holes and the diameter of said shaft portion being smaller that a diameter of said first and second groove portions whereby said projection means is inserted into said larger diameter portion and guided through said first groove portion to said second groove means where it is supported.

9. A portable type mobile radio telephone as claimed in claim 3, wherein said mounting plate has first, second and third holes, said first and second holes being used when said mobile radio telephone is vertically mounted on said wall and said second and third holes being used when said mobile radio telephone is horizontally mounted on said wall.

5. A portable type mobile radio telephone comprising:

a transceiver unit with a flat configuration and an insulating plate at the outside thereof, which is made of a synthetic resin;

battery holding means for holding a battery which is placed on one wider surface of said transceiver unit; and

a cradle for holding a handset which is formed on the one wider surface of said transceiver unit to be in parallel to said battery holding means, said cradle having engaging means engaged with said handset.

6. A portable type mobile radio telephone as claimed in claim 5, wherein said insulating plate has a plurality of projecting portions which are brought into contact with said transceiver unit and said insulating plate further has a number of radiating holes.

7. A portable type mobile radio telephone comprising:

a transceiver unit with a flat configuration;

said transceiver unit having a guide hole and a first connector at one end narrower surface;

battery holding means mounted on a wider surface of said transceiver unit;

a cradle mounted on the wider surface of said transceiver unit to be arranged in parallel to said battery holding means; and

a base plate attached to said battery holding means and said cradle so as to be interposed between said battery holding means and said cradle, and said transceiver unit, said base plate having a curved portion facing the one narrower surface of said transceiver unit, said curved portion having a guide pin and a second connector so that said first and second connectors are guided by connection of said guide pin and said guide hole and coupled with each other when said base plate is moved in a parallel direction with respect to the wider surface of said transceiver unit on which said battery holding means is mounted.

8. A portable type mobile radio telephone as claimed in claim 7, wherein said transceiver unit has an engaging projection on the wider surface thereof on which said battery holding means is mounted, and said base plate having an engaging hole which is positioned to face said engaging projection when said first and second connectors are coupled to each other, said engaging projection having a shaft portion and a larger diameter cap portion mounted on one end portion of said shaft portion and said engaging hole having a larger diameter portion and a groove portion communicated with said larger diameter portion, said larger diameter portion allowing insertion of said larger diameter cap portion and said groove portion allowing insertion of said shaft portion, and said mobile radio telephone further comprising an engaging means placed in the opposite side to said engaging projection with respect to said base plate, said engaging means including an engaging member placed on said engaging hole, said engaging member being resiliently deformable so as to allow insertion of said engaging projection into said engaging hole, said engaging member being arranged so as to lock said engaging projection when said engaging projection is guided along said groove portion of said engaging hole.
