The gist of the embodiment of the present invention according to FIGS. 3 and 4 is that when the user manually opens and closes the sub body, the sub body 120 is controlled to be fully open and closed unless it is fully opened or closed.

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 a user manually opens the subbody 120 according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 3. When the user opens the subbody 120 as shown in FIG. 3, the control unit 200 proceeds to step 302 of FIG. 3 to determine whether the open sensor 236 and the close sensor 238 are both undetected. The open sensor 236 generates a sub-body full open detection signal when the sub-body 120 is fully open and outputs the signal to the controller 200, and the close sensor 238 when the sub-body 120 is completely closed. The sub-body completely close detection signal is generated and output to the control unit 200. Therefore, the meaning that the open sensor 236 and the close sensor 238 are both undetected means that the user did not completely open the subbody 120 when the subbody 120 was manually opened.

In step 302 of FIG. 3, if it is determined that both the open sensor 236 and the close sensor 238 are not detected, the control unit 200 proceeds to step 304. In step 304, the controller 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 306 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 opening detection signal is received, the control unit 200 proceeds to step 310 of FIG. 3 to stop driving of the sub-body opening and closing motor 234. However, if the sub-body full open detection signal is not received from the open sensor 236 in step 306 of FIG. 3, the flow proceeds to step 308 to determine whether a predetermined time has elapsed from the motor driving control time point. The preset time is a time required for the subbody opening / closing motor 234 to fully open the subbody 120 when the user manually opens the subbody 120 but is not completely open. do. If the predetermined time has elapsed, the process proceeds to step 310 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 manually opens the sub-body 120 according to an embodiment of the present invention. The process of FIG. 4 is performed opposite to the process of FIG.

When the user opens the subbody 120 as shown in FIG. 4, the control unit 200 proceeds to step 402 of FIG. 3 to determine whether both the open sensor 236 and the close sensor 238 are undetected. The open sensor 236 generates a sub-body full open detection signal when the sub-body 120 is fully open and outputs the signal to the controller 200, and the close sensor 238 when the sub-body 120 is completely closed. The sub-body completely close detection signal is generated and output to the control unit 200. Therefore, the open sensor 236 and the close sensor 238 are both undetected means that the user does not completely close the subbody 120 when the user manually closes the subbody 120.

In step 402 of FIG. 4, if it is determined that both the open sensor 236 and the close sensor 238 are not detected, the control unit 200 proceeds to step 404. In step 404, the control unit 200 performs motor driving control so that the subbody 120 is completely 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 / closing motor 234 in the clockwise direction. Thereafter, in step 406 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 410 of FIG. 4 to stop driving of the sub-body opening and closing motor 234. However, if the sub-body full close detection signal is not received from the close sensor 238 in the determination of step 406 of FIG. 4, the method proceeds to step 408 to determine whether a predetermined time has elapsed from the motor driving control time point. The preset time is a time required for the subbody opening / closing motor 234 to completely close the subbody 120 when the user manually closes the subbody 120 but does not completely close the subbody 120. 0.2 seconds. If the predetermined time has elapsed, the process proceeds to step 410 of FIG. 4 to stop the driving of the sub-body opening and closing motor 234.
