DEVICE FOR DRIVING A SUB-BODY OF A MOBILE TELEPHONE, CONCERNED WITH SECURING A FREE SPACE IN A RATARY

摘要

PURPOSE: A device for driving a sub-body of a mobile telephone is provided to secure a free space in a rotary part by arranging a part of a device of driving a sub-body in a sub-body outside the rotary part. CONSTITUTION: A mobile telephone is formed of a main body and a sub-body(110) rotatively combined with the main body. Fixing parts are protruded at one side of the main body. A rotary part(108) is formed at one end of the sub-body(110) to be rotatively combined with the fixing part of the main body. A driving part is installed in the sub-body(110), placing a part in the rotary part(108), and includes a motor(116) and a reducer(120) reducing rotary force of the motor. Couplings have one ends connected with an output of the reducer in the rotary part(108), and other ends connected with the fixing parts by an elastic element. The couplings are arranged in parallel with a part of a driving device.
