Docking device

1. A docking device comprising:

a device mounting part mounts a portable information device having a forward-descending angular position so that said portable information device comes in contact with a n external face for use at a front end and is supported by said device mounting part at a rear end;

a connection part, which stands by said device mounting part, is opposed to a lateral face of said portable information device when said portable information device is mounted on the device mounting part;

a connector disposed at said connection part to be rotatable, wherein said connector being connectable to a connection terminal at said lateral face of said portable information device mounted on said device mounting part;

a detector detects a mounting angle of said portable information device mounted on said device mounting part; and

an angle adjustment part rotates said connector according to said mounting angle detected by said detector to adjust said angle of said connector to be connectable to said connection terminal.

2. The docking device of claim 1 , wherein said angle adjustment part joins rotatably relative to a base to support said device mounting part and said connection part via a rotary shaft.

3. The docking device of claim 2 , wherein said connector moves towards and away from said connection terminal.

4. The docking device of claim 3 , wherein said angle adjustment part includes at least a slide base to support said supporting member to be slidable along a direction in which said connector moves towards and away from said connection terminal.

5. The docking device of claim 4 , wherein said slide base joins with said base so as to be rotatable via said rotary shaft.

6. The docking device of claim 2 , wherein said connector is supported at said supporting member via a floating device member.

7. The docking device of claim 1 , further comprising a moving device to move said connector having said angle adjusted by said angle adjustment part towards and away from said connection terminal.

8. The docking device of claim 1 , wherein a plurality of the connection terminals is arranged side-by-side at the lateral face of said portable information device in a front-rear direction.

9. The docking device of claim 8 , wherein a plurality of the connectors is arranged side-by-side so as to correspond to said connection terminals.

10. The docking device of claim 2 , wherein said angle adjustment part includes at least a supporting member to support said connector.

11. The docking device of claim 10 , wherein

said connector moves towards and away from said connection terminal,

said angle adjustment part includes at least a slide base to support said supporting member to be slidable along a direction in which said connector moves towards and away from said connection terminal,

said slide base joins with said base so as to be rotatable via said rotary shaft, and

said interlocking member is fixed to said slide base.

12. The docking device of claim 2 , wherein said detector includes at least a vertically-moving member that moves up and down due to pressing with a bottom face of said portable information device mounted on said device mounting part.

13. The docking device of claim 12 , wherein said angle adjustment part includes at least an interlocking member to interlock moving up-down of said vertically-moving member with rotating of said supporting member.

14. The clocking device of claim 2 , wherein said device mounting part includes at least a leg that comes in contact with a bottom face of said portable information device to be mounted.

15. The docking device of claim 14 , wherein said leg is disposed on a line extended from a center axis of said rotary shaft.

16. The docking device of claim 15 , further comprising a positioning member to position a rear face of said portable information device to be mounted, on said device mounting part.
