Generally, portable wireless terminals are classified into bar type terminals, flip type terminals and folder type terminals, in accordance with an external form thereof.
The bar type terminals are configured so that a single body housing thereof is provided with a keypad as data input means, a display device as data output means, and receiver and transmitter modules. Such a bar type terminal has an advantage that its entire construction is simple.
The flip type terminals generally comprise a terminal body, a flip cover, and a hinge mechanism adapted to rotatably couple the flip cover to the terminal body. Although the terminal body of the flip type terminal is configured in the same manner as that of the bar type terminal, the flip cover is adapted to cover a keypad provided on the terminal body when the terminal is in a call waiting mode. Thus, the flip type terminal has an advantage that it can prevent the malfunctioning of the keypad.
The folder type terminals generally comprise a terminal body, a folder, and a hinge mechanism adapted to rotatably couple the folder to the terminal body. The folder is adapted to be opened away from or closed to the terminal body according to its rotation relative to the terminal body. In a call waiting mode wherein the folder is folded to come into close contact with the terminal body, the folder is adapted to cover a keypad provided on the terminal body, thereby preventing the malfunctioning of the keypad. Further, in a conversation mode wherein the folder is unfolded to a certain opened position, the portable wireless terminal is adapted to ensure a sufficient distance between transmitter and receiver modules, thereby advantageously achieving miniaturization thereof.

FIG. 1 is a perspective view illustrating a bar type portable wireless terminal, designated as a reference numeral 100, in accordance with a preferred embodiment of the present invention. FIG. 2 is a perspective view illustrating a state wherein an upper body, designated as a reference numeral 102, of the terminal 100 shown in FIG. 1 is rotated. FIG. 3 is a perspective view illustrating sliding movements of a slidable cover, designated as a reference numeral 123, provided in the terminal 100 shown in FIG. 1. As shown in FIGS. 1 to 3, the portable wireless terminal 100 according to the preferred embodiment of the present invention is a bar type terminal comprising a lower body 101 and upper body 102. The upper body 102 is rotatably coupled to an upper end of the lower body 101.
The lower body 101 is provided at its front surface with a keypad 111 and transmitter 113, containing a microphone, below the keypad 111. The lower body 101 is also provided at a first side surface with a camera lens unit 115 and a second side surface with an image reproduction device 117. The camera lens unit 115, shown in FIG. 2, is installed inside the lower body 101 in such a fashion that its exposure window faces a sideward direction of the lower body 101. The image reproduction device 117, shown in FIG. 4, serves to reproduce images captured by the camera lens unit 115.
Referring to FIGS. 6 and 7, the image reproduction device 117 is adapted to be protected by a protective cover 119a or 119b, except during image reproduction. FIG. 6 illustrates a rotary type protective cover 119a, which is rotatably coupled to one side end of the image reproduction device 117 relative to a rotation axis A2. FIG. 7 illustrates a sliding type protective cover 119b, which is adapted to slidably reciprocate in a direction of arrow B2.
Referring to FIGS. 1 to 3, the upper body 102 is rotatably coupled to the upper end of the lower body 101 such that the upper body 102 is rotatable in a twisting direction relative to the rotation axis A1 extending in a longitudinal direction of the lower body 101. The upper body 102 is provided at its front surface with a display device 121, and a receiver 125, containing a speakerphone, above the display device 121. The display device 121 is preferably embodied as a touch screen, and adapted to display images captured by the camera lens unit 115.
The upper body 102 is also provided at its upper end surface with a MMC (man machine communication) slot 104. Referring to FIG. 5 illustrating the MMC slot 104 in detail, the MMC slot 104 is provided therein with an ear-microphone jack 143 and a multi-connector 145. The multi-connector 145 enables the portable wireless terminal 100 to be connected to a personal computer, external storage device, and so on. The MMC slot 104 is adapted to be protected by a slot cover 141 rotatably coupled thereto relative to a rotation axis A3 extending in a transverse direction of the terminal 100. The slot cover 141 serves to prevent impurities from entering the ear-microphone jack 143 or multi-connector 145. Although not shown, the slot cover 141 may be constructed as a sliding type cover.
Lower and upper bodies 101 and 102 of the terminal 100 are formed with first and second sliding guides 103a and 103b, respectively. The first sliding guides 103a extend along both longitudinal edges of the display device 121, and the second sliding guides 103b extend along both longitudinal edges of the keypad 111. Where the keypad 111 and display device 121 face the same direction, i.e. when the lower and upper bodies 101 and 102 are not rotated, the first sliding guides 103a are aligned with the second sliding guides 103b. 
The terminal 100 is provided at its front surface with a slidable cover 123, which is adapted to move slidably along the first and second sliding guides 103a and 103b. Namely, the slidable cover 123 is movable in a direction of arrow B1, shown in FIGS. 1 and 3, along the first and second sliding guides 103a and 103b. Preferably, in order to protect the display device 121 while allowing a user to look at information displayed on the display device 121, the slidable cover 123 is made of transparent materials such as glass and acrylic. FIG. 1 illustrates a state wherein the slidable cover 123 is positioned on the display device 121, and FIG. 2 illustrates a state wherein the slidable cover 123 is positioned on the keypad 111. Although not shown in FIGS. 1 and 2, it should be clearly understood that the slidable cover 123 has to be fixed when it is positioned on the keypad 111.
When the slidable cover 123 is positioned on the upper body 102, a part of the slidable cover 123, namely, its one end portion, is also positioned on the keypad 111 of the lower body, thereby causing the slidable cover 123 to constrain the rotation of the upper body 102. This is possible since a length of the first sliding guides 103a provided at the upper body 102 is shorter than that of the second sliding guides 103b provided at the lower body 101 and the slidable cover 123 has the same length as the second sliding guides 103b provided at the lower body 101. Similarly, it should be clearly understood that the rotation of the upper body 102 is also constrained where the length of the first sliding guides 103a is longer than that of the second sliding guides 130b and the slidable cover 123 has the same length as the first sliding guides 103a. 
In addition, if the slidable cover 123 has a length shorter than the lengths of the respective first and second sliding guides 103a and 103b, the upper body 102 is adapted to freely rotate regardless of a position of the slidable cover 123. In this way, the slidable cover 123 also functions to selectively limit the manipulation of the terminal 100, in addition to its protective function. That it to say, when the slidable cover 123 is positioned on the upper body 102, a user is allowed to manipulate the terminal 100 or input data only through the keypad 111. When the slidable cover 123 is positioned on the lower body 101, the touch screen is operable as a PDA terminal mode enabling data input using a pen. Therefore, where the terminal 100 is manipulated for an image capturing purpose or a data input purpose using the touch screen and pen in a state wherein the slidable cover 123 is positioned on the lower body 101, it is possible to prevent the malfunctioning of the keypad 111. As stated above, the slidable cover 123 functions as an operation conversion switch.
FIG. 4 is a perspective view illustrating a state wherein the terminal 100 shown in FIG. 1 is used as a digital imaging device. The upper body 102 of the terminal 100 is shown in FIG. 4 with the lower body 101 rotated at 90° about the rotation axis A1, and the slidable cover 123 is positioned on the keypad 111. In this state, the camera lens unit 115 is used to capture images and the captured images can be displayed selectively on the image reproduction device 117 or display device 121. Thus, it should be clearly understood that the portable wireless terminal 100 can be utilized as a digital camera as well as the digital imaging device. For image capturing using the camera lens unit 115, the upper body 102 is provided at its one side surface with a shutter button 126 (shown in FIG. 3). The shutter button 126 may be substituted with one selected from among key buttons on the keypad 111 of the lower body 101, in accordance with the arrangement of the sliding cover 123 and sliding guides, 103a and 103b. 
Meanwhile, the terminal 100 is configured to enable a user to edit the images captured by the camera lens unit 115 in real time while confirming them through the image reproduction device 117. This is possible since the display device 121 is preferably constructed as a touch screen which can be set to display an image edition menu when the terminal 100 is operated as the digital imaging device. In addition, the terminal 100 is adapted to be connected to certain external devices through the multi-connector 145 installed at the upper body 102, thereby ensuring a sufficient storage capacity required to store the captured images. Furthermore, if an image capturing direction of the camera lens unit 115 and an image display direction of the display device 121 are appropriately set, e.g. set in the same plane, a user can conveniently perform video communications using the terminal 100.
As apparent from the above description, a portable wireless terminal of the present invention can be used as a digital image device according to requirements of a user, as well as functioning as a portable phone, PDA and so on. Namely, the portable wireless terminal in accordance with the present invention has an advantage that it can function as a multimedia device as well as a mobile communication terminal. Where the portable wireless terminal is used as the multimedia device, the user can conveniently use it without a limitation of storage capacity since it is configured to be easily connected to certain external devices using a multi-connector provided therein. Furthermore, the portable wireless terminal is configured to allow the user to directly edit the captured images using a display device constructed as a touch screen while confirming the images using an image reproduction device thereof. This improves a convenience of use as the multimedia device.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
