Problems solved by technology

However, due to the narrow setting space, it is not possible to list all the buttons required by the user
If the number of buttons is increased, when all the buttons needed by the user are listed, the space occupied by one button is too small and it is inconvenient to operate. When the user needs to make a phone call or send text, it is inconvenient to find because of the existence of special keys for games. desired button
Also, aesthetically, the multitude of buttons is confusing and may increase the size of the mobile terminal, so it is by no means the preferred solution

Embodiment 1

[0037] figure 2 is a perspective view showing the back of the mobile terminal according to the first embodiment of the present invention, image 3 is a perspective view showing a state where the display screen of the mobile terminal according to the first embodiment of the present invention is partially opened, Figure 4 It is a perspective view showing the state where the first and second keyboard parts of the mobile terminal according to the first embodiment of the present invention are opened.

[0038] As shown in the figure, the mobile terminal of the present invention includes a terminal body 100 , a keyboard part 200 , and an auxiliary keyboard part 300 .

[0039] The terminal body 100 includes a main body part 110 built with circuit components capable of communication and a display screen part 120 configured to slide up and down. The main body 110 is provided with a plurality of button-shaped input keys 111 capable of inputting numbers and characters. One side of the m...

Embodiment 2

[0060] Figure 7 is a sectional view showing the operation unit of the mobile terminal according to the second embodiment of the present invention. In the description of the second embodiment, the same parts as those of the first embodiment are given the same reference numerals, and their descriptions are omitted.

[0061] like Figure 7 As shown, it further includes a third elastic body 445 connected to the first moving guide 430 and moving the first moving guide 430 according to elastic force. The third elastic body 445 is an elastic spring arranged along the guide groove 435 , one end of the third elastic body 445 is connected to the anchor portion 431 of the first moving guide groove 430 , and the other side is connected to the guide groove 435 On the protrusion 446 formed on the end of the Preferably, the third elastic body 445 is initially set to pull the first moving guide 430 in a tensioned state.

[0062]The first moving guide groove 430 moves according to the ela...

Embodiment 3

[0064] Figure 8 It is a perspective view of the mobile terminal according to the third embodiment of the present invention, and a game keyboard can be set on the additional keypad 300 . Such as Figure 8 As shown, the first additional keypad 330 is provided with direction keys to control the movement of game characters in the game, and the second additional keypad 340 is arranged with a plurality of action keys at an appropriate distance without interfering with each other. In particular, when operating the button, the user has to repeatedly press the operation button. The operating buttons should therefore be large and spaced apart from each other, and an additional keypad can provide this space.

[0065] Figure 9 is a perspective view of another modification of the third embodiment of the present invention, the display screen portion 130 slides along the width of the main body portion 110 instead of the length of the main body portion 110 . In this configuration, the d...

Abstract

Disclosed is a mobile terminal including a terminal body; a display portion movably mounted on the terminal body; and a keyboard portion provided to be slidable on the bottom of the terminal body and selectively exposing an auxiliary keypad. Also, disclosed is a mobile terminal including a body portion; a display portion mounted on the body portion and having a display; a keyboard portion provided on the body portion to be situated therein or slid to be opened to the outside of the body portion; an auxiliary keypad provided on the keyboard portion; and an operating unit attached to the terminal body and enabling the keyboard portion to be opened via an operation button, but, when the display portion is opened, locking the closed keyboard portion even in the case the operation button is pressed. Due to the auxiliary keypad, it is possible to improve the effectiveness in creating a text message and make a game more interesting. Also, in the case the auxiliary keypad is not used to make a call, a locking function is also provided to prevent opening of the keypad to the outside, thereby not interfering with the call.
