On the other hand, the second standard keyboard portion 230 mounted in the keyboard cover 200 is attached to the inner surface of the cover housing 210, is a keyboard formed of the rest of the keyboard configuration other than the first standard keyboard portion 130. .

In addition, the second PCB 240 mounted in the keyboard cover 200 is closely connected between the dial button portion 220 and the second standard keyboard portion 230, and the dial button portion 220 and the second PCB 240 are closely connected to each other. 2 Recognizes the pressed state of the corresponding button of the standard keyboard unit 230 and outputs the corresponding keyboard recognition data to the main PCB (120).

On the other hand, the locking jaw 250 mounted in the keyboard cover 200 is formed on the left side of the cover housing 210, the hook formed so as to catch the fixed support 162 mounted in the cover opening and closing means 160 It's a chin.

In addition, the FPCB 300 serves to electrically connect the main PCB 120 mounted in the main body 100 and the second PCB 240 mounted in the keyboard cover 200.

Next, a process of inputting text by a user using a portable wireless telephone with a standard keyboard having the above configuration will be described.

Figure 3 is an external view of a portable cordless phone with a standard keyboard according to an embodiment of the present invention, Figure 4 is a keyboard cover of the portable cordless phone with a standard keyboard according to an embodiment of the present invention in the open state 5A, 5B, and 5C are flowcharts illustrating an opening state of a keyboard cover of a portable wireless telephone with a standard keyboard according to an embodiment of the present invention, and FIGS. 6A and 6B. 6C, 6D, and 6E are flowcharts illustrating a state in which a keyboard cover of a portable wireless telephone with a standard keyboard according to an embodiment of the present invention is closed.

First, the user opens the keyboard cover 200 of the portable cordless phone to which the standard keyboard is attached.

At this time, when the user describes the process of opening the keyboard cover 200 with reference to Figures 5a, 5b and 5c, the user first the keyboard cover release button (161) in the portable wireless telephone as shown in Figure 5a Press).

Then, the fixed support 162 is moved to the left / right as shown in Figure 5b as the keyboard cover release button 161 is pressed, thereby the locking step formed in the keyboard cover 200 250 is to be separated from the fixed support 162.

Accordingly, the keyboard cover 200 is opened from the main body 100 as shown in FIG. 5C, and is then horizontal with the main body 100 as shown in FIG. 4.

On the other hand, the fixed support 162 is moved to the left / right as the keyboard cover release button 161 is pressed, and is restored to its original position by the compression spring 163.

Therefore, after opening the keyboard cover 200 as described above, the user inputs a character to be input using the first and second standard keyboard parts 130 and 230.

Then, the first PCB 140 and the second PCB 240 recognizes the pressed state of the corresponding button of the first standard keyboard portion 130 and the second standard keyboard portion 230 and the corresponding keyboard The recognition data is output to the main PCB 120.

Subsequently, the main PCB 120 receives the keyboard recognition data output from the first PCB 140 and the second PCB 240, and performs a text message service by performing a control operation of a portable wireless telephone corresponding to the keyboard recognition data. Will perform the action.

Meanwhile, the user closes the keyboard cover 200 again when the character input operation is completed as described above, and the process of closing the keyboard cover 200 by the user is illustrated in FIGS. 6A, 6B, 6C, 6D and 6. This will be described with reference to 6e.

First, the user manually pushes the keyboard cover 200 toward the main body 100 as shown in FIG. 6A.

Then, the keyboard cover 200 is moved to the main body 100, as shown in Figure 6b and 6c, after the user continues to apply a force to the keyboard cover 200 to the keyboard cover 200 The locking step 250 is formed is caught by the fixed support 162 as shown in Figure 6d.

Therefore, the keyboard cover 200 is closed by being in close contact with the main body 100 as shown in FIG. 6E.

As described above, according to the portable radiotelephone with a standard keyboard according to the present invention, the portable radiotelephone is equipped with a standard keyboard so that the user can input characters through the standard keyboard during character input, thereby allowing the user to carry the portable radio. In addition to making texting services faster and more convenient through the phone, it also has the outstanding effect of reducing battery consumption and call charges due to shorter input time.
