Perform. Further, even if the automatic opening and closing control is repeated a predetermined number of times, if the complete opening and closing is not performed, the subbody 120 is controlled to be in an initial state.

Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1A, 2B, 2, 3, and 4.

First, an operation when the user automatically opens the subbody 120 according to an exemplary embodiment of the present disclosure will be described in detail with reference to FIG. 3. If the user automatically controls the sub-body 120 as shown in FIG. 3, the control unit 200 determines this in step 300 of FIG. 3, and proceeds to step 302. When the user presses the automatic folder opening and closing key 180 or pulls out the antenna of the antenna device 130, the control unit 200 pulls out the key data or the antenna corresponding to the pressing of the automatic folder opening and closing key 180, and the antenna extension detecting unit 240. The automatic opening control is recognized by receiving the data detected by. In step 302, the control unit 200 performs motor driving control so that the subbody 120 is opened from the main body 110. That is, the sub-body 120 is opened from the main body 110 by controlling the motor driving unit 232 to rotate the sub-body opening and closing motor 234 in the counterclockwise direction. Thereafter, in step 304 of FIG. 3, it is determined whether the sub-body full open detection signal is received from the open sensor 236 indicating that the sub-body 120 is fully opened. If the sub-body full open detection signal is received, the control unit 200 proceeds to step 318 of FIG. 3 to stop driving of the sub-body opening and closing motor 234.

On the other hand, if the sub-body full open detection signal is not received from the open sensor 236 in the determination of step 304 of FIG. The preset time is usually a time required for the subbody opening / closing motor 234 to fully open the subbody 120, for example, 1.2 to 1.5 seconds. The fact that the sub-body full open detection signal is not received from the open sensor 236 and the predetermined time has elapsed from the time of controlling the motor driving is due to physical factors (for example, the user intentionally holding the sub body 120). It is not fully open.

In step 306 of FIG. 3, if the predetermined time has elapsed, the process proceeds to step 308 of FIG. 3 to increase the motor driving repeat count by one from the initial value (= 0). In order to increase the number of repetition of the motor drive, an embodiment of the present invention uses a counter provided therein. Thereafter, the controller 200 determines whether the motor driving repetition number is N (N is a natural number) in step 310 of FIG. 3. If the number of motor drive times is not N times, the flow returns to step 302 and the operation from that step is performed again.

In step 310 of FIG. 3, when the number of times of repeating the motor drive becomes N, N is a natural number, the control unit 200 controls the subbody 120 to be closed. That is, the sub-body 120 is closed on the main body 110 by controlling the motor driving unit 232 to rotate the sub-body opening and closing motor 234 in the clockwise direction. Thereafter, in step 314 of FIG. 3, it is determined whether the sub-body full close detection signal indicating that the sub-body 120 is completely closed is received from the close sensor 238. If the sub-body full close detection signal is received, the control unit 200 proceeds to step 318 of FIG. 3 to stop driving of the sub-body opening and closing motor 234.

On the other hand, if the sub-body full close detection signal is not received from the close sensor 238 in the determination of step 314 of FIG. 3, the process proceeds to step 316 to determine whether a predetermined time has elapsed from the time point of the motor driving control. The preset time is usually a time required for the subbody opening / closing motor 234 to completely close the subbody 120, for example, 1.2 to 1.5 seconds. If the predetermined time has elapsed in step 316 of FIG. 3, the flow proceeds to step 318 of FIG. 3 to stop driving of the sub-body opening and closing motor 234.

Next, with reference to Figure 4 will be described in detail the operation when the user automatically closes the sub-body 120 according to an embodiment of the present invention. When the user performs the automatic closing control of the sub-body 120 as shown in FIG. 4, the control unit 200 determines this in step 400 of FIG. 4 and proceeds to step 302. When the user presses the automatic folder opening and closing key 180 or inserts the antenna of the antenna device 130, the control unit 200 according to the key data or the antenna corresponding to the pressing of the automatic folder opening and closing key 180, antenna extension detecting unit 240 The automatic closing control is recognized by receiving the detected data. In step 402, the control unit 200 performs motor driving control so that the subbody 120 is closed on the main body 110. That is, the sub-body 120 is closed on the main body 110 by controlling the motor driving unit 232 to rotate the sub-body opening and closing motor 234 in the clockwise direction. Thereafter, in step 404 of FIG. 4, it is determined whether the sub-body full close detection signal indicating that the sub-body 120 is completely closed is received from the close sensor 238. If the sub-body full close detection signal is received, the control unit 200 proceeds to step 418 of FIG. 4 to stop driving of the sub-body opening and closing motor 234.

On the other hand, if the sub-body full close detection signal is not received from the close sensor 238 in the determination of step 404 of FIG. 4, the process proceeds to step 406 to determine whether a predetermined time has elapsed from the time point of the motor driving control. The preset time is a time required for the subbody opening / closing motor 234 to completely close the subbody 120, for example, 1.2 to 1.5 seconds. The fact that the sub-body full close detection signal is not received from the close sensor 238 and the preset time has elapsed from the time of the motor drive control may be due to physical factors (for example, the user intentionally holding the sub body 120). It is not completely closed.

In step 406 of FIG. 4, if the predetermined time has elapsed, the process proceeds to step 408 of FIG. 4 to increase the motor driving repeat count by one from the initial value (= 0). In order to increase the number of repetition of the motor drive, an embodiment of the present invention uses a counter provided therein. Thereafter, the controller 200 determines whether the motor driving repetition number is N (N is a natural number) in step 410 of FIG. 4. If the number of motor driving times has not reached N times, the process returns to step 402 to perform the operation from that step again.

In operation 410 of FIG. 4, when the motor driving repetition number reaches N, N is a natural number, the control unit 200 controls the subbody 120 to be opened. That is, the sub-body 120 is opened from the main body 110 by controlling the motor driving unit 232 to rotate the sub-body opening and closing motor 234 in the counterclockwise direction. Thereafter, in operation 414 of FIG. 4, it is determined whether the sub-body fully open detection signal indicating that the sub-body 120 is fully opened is received from the open sensor 236. If the sub-body full open detection signal is received, the control unit 200 proceeds to step 418 of FIG. 4 to stop driving of the sub-body opening and closing motor 234.

On the other hand, if the sub-body full open detection signal is not received from the open sensor 236 in the determination of step 414 of FIG. 4, the method proceeds to step 416 to determine whether a predetermined time has elapsed from the time of the motor driving control. The predetermined time is a time required for the subbody opening / closing motor 234 to fully open the subbody 120, for example, 1.2 to 1.5 seconds. In operation 416 of FIG. 4, when the predetermined time has elapsed, the process proceeds to step 418 of FIG. 4 to stop the driving of the sub-body opening and closing motor 234.
