In addition, according to an exemplary embodiment of the present invention, when the call is received, the sub-body automatic opening and the call path formation control are performed as shown in FIGS. 3A and 3B, and when the call is terminated, the sub-body automatic closing control is performed as shown in FIG. 3B.

Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1A, 2B, 2, 3A, and 3B.

First, an operation of forming a call according to an embodiment of the present invention will be described with reference to FIG. 3A. When the call is received by the control unit 200 through the wireless unit 210, the control unit 200 detects the call in step 300 of FIG. 3A and proceeds to step 302. In step 302, the control unit 200 generates a ring tone so that the user recognizes a call and proceeds to step 304. In step 304 of FIG. 3A, the controller 200 performs motor driving control so that the subbody 30 is opened from the main body 20. That is, the sub-body 30 is opened from the main body 20 by controlling the motor driving unit 260 to rotate the sub-body opening / closing motor 270 counterclockwise. Thereafter, in step 306 of FIG. 3A, it is determined whether the sub-body full open detection signal is received from the open sensor 280 indicating that the sub-body 30 is fully opened. If the sub-body full opening detection signal is received, the control unit 200 proceeds to step 310 of FIG. 3A to stop driving of the sub-body opening and closing motor 270. Then proceed to step 312. In step 306 of FIG. 3A, if the sub-body full open detection signal is not received from the open sensor 280, the controller proceeds to step 308 to determine whether a predetermined time has elapsed from the time of controlling the motor drive. Normally, it is an estimated time taken for the subbody opening / closing motor 270 to fully open the subbody 30. The estimated time to fully open the subbody is set in advance to avoid the inconvenience that the subbody opens too soon, or the time when the user feels bored because it opens too late. The estimated time required can be appropriately preset and adjustable within the range of 0.5 to 2.0 seconds. In a preferred embodiment of the present invention, for example, 1.2 to 1.5 seconds. If the preset time has elapsed, the process proceeds to step 310 of FIG. 3A to stop driving of the sub-body opening and closing motor 270. Then proceed to step 312. In step 308, when the subbody is not fully opened due to an external obstacle, the subbody opening / closing motor 270 continues to be driven until the subbody is completely open. The maximum operating time of the motor 270 is controlled. In step 312, the controller 200 determines whether there is an input of a key corresponding to the formation of a call path from the user. If there is a key input corresponding to the formation of a call path from the user in step 312, the controller 200 proceeds to step 316 to control the voice processor 220 to form a call path. If a key corresponding to the formation of the call path by the user is input while the sub-body is not completely open, the motor driving unit 260 is continuously operated until the sub-body is completely opened after the call path is formed. The controller 200 proceeds to step 314 when the key corresponding to the formation of the call by the user is not input in step 312. The controller 200 proceeds to [A] when the call termination is terminated due to the user not responding to the call in step 314. On the other hand, if it is determined in step 314 that the call is not terminated, the control unit 200 proceeds to step 312 again.

As described above, in the embodiment of the present invention, the sub-body opening / closing motor 270 is driven to open the sub-body when the call is received, so that the sub-body is opened by hand or pressing the automatic folder opening / closing key 70 when the call is received. By eliminating the inconvenience of waiting for the folder to open.

Next, an operation at the end of call reception according to an embodiment of the present invention will be described with reference to FIG. 3B.

In step 314 of FIG. 3A, when the user does not answer the call, the controller 200 determines that the call is terminated, and proceeds to [A]. The control unit 200 proceeds to step 316 to perform the motor drive control so that the sub-body 30 is closed on the main body (20). The control unit 200 causes the sub-body 30 to close on the main body 20 by rotating the sub-body opening / closing motor 270 in a clockwise direction by controlling the driving of the motor driving unit 260 in step 316. As described above, in the embodiment of the present invention, when the call termination is determined, the sub-body opening and closing motor 270 is driven to automatically restore the terminal to the state before the call is received.

After performing step 316, the control unit 200 determines whether a sub-body full close detection signal indicating that the sub-body 30 is completely closed is received from the close sensor 290 in step 318. If the sub-body full close detection signal is received, the control unit 200 proceeds to step 322 of FIG. 3B to stop driving of the sub-body opening and closing motor 270. In step 318 of FIG. 3B, if the complete close detection signal is not received from the close sensor 290, the process proceeds to step 320 to determine whether a predetermined time has elapsed from the time of controlling the motor driving. The preset time is an expected time normally required for the subbody opening / closing motor 270 to completely close the subbody 30. The estimated sub-body full closing time is set in advance to avoid the time when the sub-body is closed too soon to inconvenience the user or is closed too late to make the user feel bored. The estimated time required can be appropriately preset and adjustable within the range of 0.5 to 2.0 seconds. In a preferred embodiment of the present invention, for example, 1.2 to 1.5 seconds. If the preset time has elapsed, the process proceeds to step 322 of FIG. 3B to stop the driving of the sub-body opening and closing motor 270.
