1 is an exploded perspective view of a conventional wallet PC.

Referring to FIG. 1, the hardware of a conventional wallet PC 10 includes a front housing 20, a rear housing 30, a frame 40, a screen 60, a board 70, and the like. The frame 40, the screen 60, the board 70, and the like are installed in an internal space formed by the combination of the front housing 20 and the rear housing 30. The screen 60 and the board 70 are coupled to the frame 40 and installed in the inner space. The screen 60 and the board 70 have a structure that is not directly coupled to the front housing 20 or the rear housing 30. This structure prevents the impact from being transmitted directly to the screen 60 and the board 70 when an impact is applied to the housings 20 and 30 from the outside. This structure can prevent the screen 60 and the board 70 from being damaged by an external impact. The frame 40 is formed to have a structure seated in the front housing 20 and the rear housing 30. The frame 40 is coupled to the front housing 20 by screws 76. The screw 76 is coupled to the boss 24, which is formed in the front housing 20, through a fixing rib formed in the frame 40.

In this conventional wallet PC, the frame 40 is configured to be coupled to the front housing 20 by only one screw 76. Of course, the frame 40 may be configured to be coupled to the rear housing 30, and the frame 40 may be coupled to the front housing 20 or the rear housing 30 in various other ways.

The frame 40 has a first face 42 and a second face 44, which are faces opposite each other. The first face 42 and the second face 44 may be any face on the frame 40. The screen 60 is coupled to the first side 42, and the board 70 is coupled to the second side 44. The display screen of the screen 60 is exposed to the outside through the opening 22 formed in the front housing 20. The configuration for coupling the screen 60 and the board 70 to the frame 40 can be used in various ways.

Conventionally, a plurality of supporting ribs 46 have been used. The supporting ribs 46 are formed from the side of the frame 40. That is, the supporting ribs 46 are formed from the sides of the first face 42 and the second face 44. This configuration means that a plurality of devices can be combined in a stacked form on the frame 40. This method can be easily realized by those skilled in the art. The board 70 may maintain a constant height from the second surface 44. This can be effectively used when electronic circuits are installed on both sides of the board 70. This configuration can also be obtained in various ways.

In the related art, ribs 48 are formed on the second surface 44 to support the board 70.

The battery case 52 is integrally formed in the frame 40. The battery case 52 is equipped with a battery (not shown). The battery is attached / removed to / from the battery case 52 via a door 32 installed in the rear housing 30.

Conventionally, the speaker mounting portion 28 is formed so that the speaker can be installed on the inner surface of the front housing 20 where the battery case 52 is located. This structure makes it possible to efficiently use the internal space of the wallet PC 10, and to facilitate the assembly or disassembly of the speaker. The speaker may be coupled or disassembled through the door 32 without disassembling the wallet PC 10. Battery terminals 74 may be installed on the board 70. The battery terminals 74 allow the board 70 to be directly coupled to the battery case 52 when the board 70 is coupled to the frame 40.

The boards 70 may have switches 72 having various functions. For example, since the wallet PC 10 is implemented to use the system through a simple operation, various function buttons are provided. These switches 72 are actuated by buttons 26 installed in the front housing 20. The configuration and operation of the buttons 26 and switches 27 are general to those skilled in the art, and thus detailed descriptions thereof will be omitted. Since the wallet PC 10 is made small, there is a difficulty in configuring an electronic circuit in a small space. The positions of the buttons 26 for activating the switches 72 are configured to correspond to the switches 72, respectively. The switches 72 should each be in the range of motion of the corresponding buttons 26. If the switches 72 are not in the range of motion of the buttons 26, the switches 72 will not operate. In the related art, mediums 50 were used when the switches 72 were not in the range of motion of the buttons 26. The mediums 50 are formed integrally with the frame 40. These mediums 50 are located between the switches 72 and the buttons 26, respectively. When a user externally presses any one of the buttons 26 to operate a predetermined function, a medium corresponding to the button is operated. The switch corresponding to this medium is then activated. By the mediums 50, even if the switches 72 are installed at a position out of the movement range of the buttons 26, the operations of the switches 72 are normally performed.

The wallet PC 10 may use a method of inputting data on the screen 60 with a stylus 80. The stylus 80 may also be called a pen or a pen stylus. Various types of techniques may be used for the stylus input method. For example, there is a technique of using a conductive stylus in a stylus input method. The conductive stylus is connected to the wallet PC by a cord. The code has an internal conductor that electrically connects the stylus and the wallet PC to enable a write function on the screen. The wallet PC 10 uses screen write technology that does not require code. Screens used in such techniques are also called touch screens. In addition, the conventional wallet PC 10 allows the stylus 80 to be mounted inside the wallet PC 10. The stylus 80 is mounted to the supporter 54 formed in the frame 40. The supporter 54 may be configured in various forms. The supporter 54 is formed to have an inner surface having the same shape as the outer circumferential surface of the stylus 80. When the stylus 80 is mounted to the supporter 54, the stylus 80 is fixed by a hook 56 so as not to be detached from the supporter 54 arbitrarily. The hook 56 is coupled to a groove 82 formed on the outer circumferential surface of the stylus 80 so that the stylus 80 does not escape from the supporter 54. The hook 56 is formed in a direction in which the stylus 80 is attached / detached to / from the supporter 54. This hook 56 is formed in the form of a free end. By the structure of this free end, the hook 56 can elastically move on the inner surface of the supporter 54. In addition, the hook 56 is formed to protrude in a direction in contact with the outer circumferential surface of the stylus 80.

A first notch 29 is formed in the front housing 20, and a second notch 34 is formed in the rear housing 30. The first notch 29 and the second notch 34 form an opening when the front housing 20 and the rear housing 30 are coupled to each other. Through the opening by the first notch 29 and the second notch 34, the stylus 80 is attached / detached to / from the supporter 54.

The screen 60 and the board 70 of the wallet PC 10 are coupled to the frame 40 and positioned inside the wallet PC 10. The screen 60 and the board 70 do not have a coupling relationship with the front housing 20 and the rear housing 30 of the wallet PC 10. The frame 40 is coupled to the front housing 20 by one screw 76, and the screen 60 and board 70 are supported by the frame 40. An insulator (not shown) having elastic properties may be used at a portion where the screen 60 contacts the front housing 20. In addition, the battery case 52 may be integrally formed on the frame 40. The battery terminals installed in the battery case 52 may be installed in the board 70. The battery terminals 74 are directly coupled when the board 70 is mounted to the frame 40.

However, in the related art, a screen, a board, and the like are sequentially coupled to each other, starting from one top or bottom case, and the remaining cases are fastened. This process has a problem in that all parts must be joined at once in the manufacturing process, and all of them must be disassembled even when only the board or screen part is rested.

In addition, there is a supporting rib in preparation for bumping on the lower case side, but it is weak in impact applied directly to the screen. That is, since the screen is opened through the opening part of the wallet PC, foreign matter may be introduced from the outside, and a problem of damage may occur due to a direct impact.

The present invention has been made in order to solve the various problems as described above, in the present invention to prevent the shock from the outside from being transmitted from the portable computer to the LCD or motherboard, durability is increased, the display unit is kept clean The purpose is to produce a portable computer that can provide a higher quality image.
