The memory unit 230 includes a program memory for storing program data necessary for controlling the operation of the portable wireless terminal, and a data memory for storing data generated during control or during execution by the user.

The circuit block of the opening and closing device 10 of FIG. 2 includes a motor driving unit 232, a sub-body opening and closing motor 234, an open sensor 236, and a close sensor 238. . The motor driver 232 is driven such that the sub-body opening and closing motor 234 rotates clockwise and counterclockwise under the control of the controller 200. The open sensor 236 is a sensor that detects that the subbody 120 is completely open from the main body 110, and the close sensor 238 detects that the subbody 120 is completely closed on the main body 110. It is a sensor. The open sensor 236 and the close sensor 238 may be implemented as, for example, a hallsensor. If the open sensor 236 and the close sensor 238 is implemented as a hall sensor, the positions of the open sensor 236 and the close sensor 238 will be described below. The Hall sensor is composed of a Hall element and a magnetic. In the open sensor 236, the magnetic element 236a of the Hall element is provided on the hinge of the switch 10 as shown in FIG. 1B, and the Hall element 236b is shown in FIG. 1B. As shown in the provided on the top side of the main body (110). When the subbody 120 is completely opened by the switchgear 10, the Hall element 236b and the magnetic 236a of the open sensor 236 contact each other, and accordingly, the control unit 200 receives the subbody full open detection signal. Will output In the close sensor 238, the magnetic sensor 238a of the hall sensor is provided above the earpiece 140 of the subbody 120, as shown in FIG. 1B, and the hall element 238b of the hall sensor is illustrated in FIG. 1B. As shown, it is provided on the lowest side of the main body (110). When the subbody 120 is completely closed by the switchgear 10, the hall element 238b of the close sensor 238 and the magnetic 238a come into contact with each other, and accordingly, the control unit 200 receives the subbody full close detection signal. Will output

When the user of the portable wireless terminal 100 uses the automatic folder opening / closing key 180 or the like to control the opening and closing of the subbody automatically, the control unit 200 recognizes this and automatically opens and closes the subbody 120. Drive control of the motor driver 232. The subbody opening / closing motor 234 is rotated clockwise or counterclockwise by the drive control of the motor driving unit 232 so that the subbody 120 is closed or opened.

In addition, the sub-body opening and the call path formation control are performed as shown in FIG. 3 when the call is formed, and the sub-body closing and the call path blocking control are performed as shown in FIG. 4 at the end of the call.

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 of forming a call according to an embodiment of the present invention will be described with reference to FIG. 3. When the call is received by the control unit 200 through the wireless unit 202, the control unit 200 detects the call in step 300 of FIG. 3 and proceeds to step 301. In step 301, a ring tone is generated so that the user recognizes that the call is received. Then, when the user performs the sub-body automatic opening control using the automatic folder opening and closing key 180, the control unit 200 detects this in step 302 and proceeds to step 304. The controller 200 performs the motor driving control to open the sub body 120 from the main body 110 in step 304 of FIG. 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 open 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. Then proceed to step 312. In step 306 of FIG. 3, if the sub-body full open detection signal is not received from the open sensor 236, the controller proceeds to step 308 to determine whether a predetermined time has elapsed from the time of controlling the motor driving. 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. 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. Then proceed to step 312. In step 312, the controller 200 controls the voice processor 204 to form a call path. As described above, in the embodiment of the present invention, the call path is formed after the driving of the sub-body opening / closing motor 234 is stopped so that the noise of the sub-body opening / closing motor 234 is not transmitted to the other party. .

Next, an operation of forming a call according to an embodiment of the present invention will be described with reference to FIG. 4.

If the user makes a sub-body automatic closing control using the automatic folder opening / closing key 180 or the like in response to the termination of the call, the control unit 200 detects the determination in step 402 of the call as in step 400 of FIG. Proceed to step 404. The controller 200 determines whether the earphone is plugged into the ear jack of the wireless terminal 100 in step 404. If the earphone is not plugged into the earjack, go to step 406. The controller 200 controls the voice path 204 to block the call path in step 406 of FIG. 4. After that, the controller 200 proceeds to step 408 to perform the motor driving control so that the sub-body 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. As described above, in the embodiment of the present invention, the call path is first blocked, and then the sub-body opening / closing motor 234 is driven so that the noise of the sub-body opening / closing motor 234 is not transmitted to the other party.

After performing step 408, the controller 200 determines whether a sub-body full close detection signal indicating that the sub-body 120 is completely closed is received from the close sensor 238 in step 410. If the sub-body full close detection signal is received, the control unit 200 proceeds to step 414 of FIG. 4 to stop driving of the sub-body opening and closing motor 234. In operation 410 of FIG. 4, if the complete close detection signal is not received from the close sensor 238, the controller proceeds to step 412 to determine whether a predetermined time has elapsed from the time of controlling the motor driving. 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. If the preset time has elapsed, the process proceeds to step 414 of FIG. 4 to stop driving of the sub-body opening and closing motor 234.
