It is shown.
[24] The automatic folder opening and closing key 180 of FIG. 3 is an automatic folder opening and closing key 180 provided on the side of the bar main body 110 shown in FIGS. 1A and 1B, and the power key 190 of FIG. 3 is shown in FIG. 1B. Power key 190 on keypad 160 on main body 110 shown in FIG.
[25] Power control apparatus according to an embodiment of the present invention, the automatic folder opening and closing key 180 and the power key 190 shown in Figure 3, the first switch 300 and the second switch 302, the power supply control circuit unit 306 ), And the control unit 200 of FIG. 2. The first switch 300 and the second switch 302 of FIG. 3 are switched under the control of the controller 200 of FIG. 2. The controller 200 controls switching between the first switch 300 and the second switch 302 according to the power on / off state of the terminal.
[26] The automatic folder opening and closing key 180 and the power key 190 are connected to the battery power Vbat. The automatic folder opening and closing key 180 is commonly connected to one end of the first switch 300 and the second switch 302 through the node N1. The other end of the first switch 300 is connected to the first input end of the control unit 200. The sub-body open / close control signal is applied to the first input terminal of the controller 200. The power key 190 is commonly connected to the second input terminal of the controller 200 and the other end of the second switch 302 through the node N2. The power control signal PWC is applied to the second input terminal of the controller 200.
[27] The power supply control circuit unit 306 of FIG. 3 is a circuit for controlling the battery power supply Vbat to be supplied to and disconnected from the controller 200 and each circuit unit according to a user's power key 190 on / off. The power supply control circuit unit 306 of FIG. 3 includes a P-channel field effect transistor 310 and an NPN transistor 312.
[28] Hereinafter, an operation according to an exemplary embodiment of the present invention will be described in detail with reference to FIGS. 1A and 4B.
[29] According to an exemplary embodiment of the present invention, when the terminal is turned off, the controller 200 controls the first switch 300 to be open and the second switch 302 to be closed. Accordingly, in the power-off state, the user can turn on the power of the terminal using any one of the automatic folder opening and closing key 180 and the power key 190. In addition, when the terminal is powered on, the controller 200 controls the first switch 300 to be closed and the second switch 302 to be open. Accordingly, the automatic folder opening and closing key 180 and the power key 190 may perform unique key functions.
[30] First, when the terminal is in the power-off state, the operation according to the embodiment of the present invention will be described.
[31] When the user turns off the power of the terminal, the control unit 200 causes the first switch 300 to be open and the second switch 302 to be closed using the switch control signal SWC. Therefore, in the terminal power-off state, the first switch 300 is in the non-conduction state and the second switch 302 is in the conduction state. When the user presses the power key 190 by opening the subbody 120 or pressing the automatic folder opening / closing key 180 on the side of the main body 110 without opening the subbody 120 in the terminal power-off state. The power control signal PWC in the logic " high " state is applied to the power supply control circuit portion 306 shown in FIG. At the same time, it is also applied to the control unit 200 through the node N2. That is, when the automatic folder opening / closing key 180 is pressed, the power control signal PWC of the logic “high” state is applied to the control unit 200 through the second switch 302 in the conducting state and the node N2, and when the power key 190 is pressed. The power control signal PWC in a logic " high " state is applied to the controller 200 via the node N2.
[32] When the power control signal PWC in the logic " high " state is applied to the power supply control circuit section 306, the NPN type transistor 312 of the power supply control circuit section 306 is turned on and thus the P-channel field effect transistor 310 is also turned on. Is turned on. As the field effect transistor 310 is turned on, the battery power source Vbat is supplied to the control unit 200 as a DC power source Vdc. The control unit 200 is activated by supplying the DC power supply Vdc. In the activated state, the control unit 200 detects the power control signal PWC of the logic "high" state applied through the node N2 of FIG. 3 as one of the user's power key 190 or the automatic folder opening and closing key 180 is pressed. It is checked whether the power control signal PWC is continuously applied for a predetermined time, for example, 3-4 seconds. When the power control signal PWC is continuously applied for a predetermined time, the controller 200 applies the Vdc_holder signal to the base of the NPN transistor 312 in a logic "high" state so that the P-channel field effect transistor 310 is continuously turned on. To be on. Accordingly, even if the user stops pressing the power key, the battery power Vbat is continuously supplied to the controller 200 as the DC power Vdc. The controller 200 may control the battery power Vbat to be supplied to each circuit unit.
[33] Next, an operation according to an embodiment of the present invention when the terminal is in a power-on state is as follows.
[34] When the terminal is turned on, the controller 200 causes the first switch 300 to be closed and the second switch 302 to be opened by using the switch control signal SWC. Therefore, when the user presses the automatic folder opening and closing key 180 in the terminal power-on state, the sub-body opening and closing control signal is applied to the controller 200 through the node N1 and the first switch 300. In addition, when the user presses the power key 190 in the terminal power-on state, the power control signal PWC is applied to the controller 200 through the node N2. That is, in the terminal power-on state, the automatic folder opening and closing key 180 and the power key 190 perform a unique function.
[35] In the embodiment of the present invention has been described as an embodiment taking an automatic folder opening and closing key 180 provided on the outside of the terminal as an example, it is possible to apply to an external function key having a different function having ordinary skill in the art Will be self-evident. In addition, although the embodiment of the present invention is applied to a folding portable wireless terminal, it is also applicable to a bar type terminal which is not a folding type. Various modifications can be made without departing from the scope of the invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.
[36] As described above, the present invention implements a power key combined external function key (for example, an automatic folder opening and closing key) so that the user can turn on the power without opening the subbody even when the terminal is powered off. In addition, there is an advantage in that the terminal power-on state can perform a function unique to the terminal key.
