It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. Also, it will be understood that when an element is referred to as being “on” another element, it can be on or beneath the other element.
In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising”, will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.
Referring to FIGS. 1 and 2, a portable terminal according to a first exemplary embodiment is configured such that a position of an input part thereof may be arbitrarily changed by a user. The portable terminal may include a body 120, a display 110, and an input part 130.
According to the first exemplary embodiment, the body 120 forms, e.g., defines, the shape of the portable terminal. A device, e.g., a circuit board, a battery, etc., necessary to operate the portable terminal may be included in the body 120. Any suitable body of a portable terminal may be employed as the body 120, so a detailed description thereof is omitted.
The display 110 displays image information, e.g., text messages, video, pictures, etc. Like the body 120, any suitable display of a portable terminal may be used as the display 110, so a detailed description thereof is omitted.
Referring to FIGS. 1 and 2, the input part 130 receives an input signal of the user to execute a specific function of the portable terminal. For example, the input signal may correspond to a command signal input by the user to execute or stop a specific function.
The input part 130 may be disposed on the body 120, such that the position thereof may be changed, i.e., a changeable position. That is, while the input part 130 is disposed on the body 120, the position of the input part 130 is not fixed to one specific location on the body 120, e.g., the input part 130 is not stationary on the body 120. For example, the input part 130 may be disposed on the body 120, e.g., on a lateral side of the body 120, in a slidable manner, so the input part 130 may be moved along a surface, e.g., along the lateral side, of the body 120. For example, as will be apparent to a person of ordinary skill in the art from the foregoing description and from FIGS. 1-2, the input part 130 may move vertically along the side of the body 120 (as indicated by the arrows pointing up and down in FIGS. 1-2).
However, movement of the input part 130 is not limited to the above. According to the first exemplary embodiment, as will be apparent to a person of ordinary skill in the art from the foregoing description and from the drawings, the input part 130 may move along an entire circumference of the body 120, e.g., the input part 130 may move along each of four lateral sides of the body 120 to completely surround the circumference of the body 120 and arrive at its starting point. In other words, the input part 130 may be rotated 360 degrees along the circumference of the body 120. For example, the input part 130 in FIG. 1 may slide upward along the z-axis toward an upper edge of the body 120, turn around the edge of the body 120 to continue along the y-axis, etc., until the input part 130 reaches its starting point on the body 120. Therefore, the user may move and position the input part 130 to any desired position along the entire circumference of the body 120.
However, the position of the input part 130 is not limited to the above. For example, the input part 130 may slide only on a part of the side of the body 120. That is, the input part 130 may be disposed, such that it may slide only on a part of the side of the body 120, e.g., only on the left or only on right side of the body 120, as illustrated in FIG. 2.
Referring to FIG. 3, the input part 130 of the portable terminal according to the first exemplary embodiment may include a sliding part 131, a button part 132, and a transmission part 133.
The sliding part 131 may slide along the lateral circumference of the body 120. More specifically, the sliding part 131 may be moved along a guide 122 formed at the side of the body 120.
For example, as will be apparent to a person of ordinary skill in the art from the foregoing description and from the drawings, the guide 122 may extend along the, e.g., entire, circumference of the body 120, and may include guide protrusions 122a and 122b along the, e.g., entire, circumference of the body 120. As illustrated in FIG. 3, the guide protrusions 122a and 122b are spaced apart by a predetermined distance and disposed facing each other. That is, a pair of the guide protrusions 122a and 122b may be disposed on the lateral circumference of the body 120, facing each other.
According to the first exemplary embodiment, the guide protrusions 122a and 122b are disposed facing each other, and are open in the direction of the outside of the body 120. More specifically, the guide protrusions 122a and 122b may have a rectangular tubular shape with part of one side open, e.g., facing edges of the guide protrusions 122a and 122b may be spaced apart from each other along the x-axis to define a space therebetween.
According to the first exemplary embodiment, a guide groove 135 may be formed at a side of the sliding part 131, which may be slidably combined with the guide protrusions 122a and 122b. That is, the guide groove 135 may be formed along the side of the sliding part 131, and may correspond to the guide protrusions 122a and 122b. In other words, as shown in FIG. 3, the guide protrusions 122a and 122b may be inserted into the guide groove 135, so the guide groove 135 may fit into the space defined between the facing edges of the guide protrusions 122a and 122b, and may slide along the guide protrusions 122a and 122b. Therefore, the guide protrusions 122a and 122b may have a thickness corresponding to a width of the guide groove 135. For example, the thickness of the guide protrusions 122a and 122b, e.g., along the y-axis, may be smaller than the width of the guide groove 135, e.g., along the y-axis.
The sliding part 131 may be a bar-type member. For example, the sliding part 131 may cover the side of the body 120 with both ends thereof connected, e.g., the sliding part 131 may be a, e.g., continuous, member having a length along the entire circumference of the body 120. In another example, the sliding part 131 may cover the side of the body 120 with both ends thereof separated from each other, e.g., a length of the sliding part 131 may only partially cover the circumference of the body 120. The sliding part 131 may be formed of a flexible material, e.g., the sliding part 131 may be formed of a rubber material or any other suitable material exhibiting elasticity. Accordingly, the sliding part 131 may cover the side of the body 120, while conforming to the shape of the body 120. Furthermore, the sliding part 131 may slide along the shape of the side of the body 120.
According to the first exemplary embodiment, the button part 132 may be formed at one side of the sliding part 131, e.g., on a top of the sliding part 131. The button part 132 senses an input of the user using the portable terminal. For example, if the input part 130 is used to execute a camera function of the portable terminal, the user may generate an input signal by pressing the button part 132. Here, the input signal corresponds to a command signal by which the user instructs the camera function to be executed or stopped.
According to the first exemplary embodiment, the button part 132 may protrude from one side, e.g., surface, of the sliding part 131. The button part 132 may be formed in a protruding shape in order to allow the user to easily recognize the button part 132. For example, the button part 132 may be integrated with the sliding part 131. However, the button part 132 is not limited thereto, e.g., the button part 132 may be separated from the sliding part 131 and may be attached to one side of the sliding part 131.
Referring to FIGS. 3 and 4, when the user presses the protruding button part 132, the transmission part 133 and a receiving part 134, which will be described below, contact each other. Upon contact of the transmission part 133 and the receiving part 134, the input signal from the user is transmitted to the inside of the body 120 of the portable terminal. That is, the portable terminal performs the desired function, e.g., executes or stops the camera function.
The shape of the button part 132 is not limited to the protruding shape, e.g., the button part 132 may be flush with one side of the sliding part 131. When the button part 132 is flush with the side of the sliding part 131, a specific symbol may be marked on the side of the sliding part 131, e.g., on a surface of the sliding part 131 corresponding to the button part 132, to mark the bottom part 132 for the user.
Referring to FIG. 2, a plurality of button parts 132a and 132b may be formed on the sliding part 131. In this case, specific functions of the portable terminal may be respectively allocated to each one of the plurality of button parts 132a and 132b. For example, as will be apparent to a person of ordinary skill in the art from the foregoing description and from FIG. 2, each one of the plurality of button parts 132a and 132b may be independently positioned by the user on a different part of the sliding part 131, e.g., the button parts 132a and 132b may be on opposite side of the display 110.
Referring to FIGS. 3 and 4, the transmission part 133 is formed at the other side of the sliding part 131. For example, as will be apparent to a person of ordinary skill in the art from the foregoing description and from FIGS. 3-4, the transmission part 133 and the button part 132 are formed on opposite sides, e.g., surfaces, of the sliding part 131. Therefore, the button part 132 is on top of the sliding part 131 above the guide protrusions 122a and 122b, and the transmission part on a bottom of the sliding part 131 below the guide protrusions 122a and 122b, e.g., below the guide groove 135. The transmission part 133 comes into contact with the receiving part 134 formed in the body 120 when the button part 132 is pressed.
According to the first exemplary embodiment, when the user applies a physical force to the button part 132 to press the button part 132, the guide protrusions 122a and 122b formed at the side of the body 120 are bent toward the inside of the body 120. Thus, the transmission part 133 is moved along with the sliding part 131 toward the inside of the body 120. Accordingly, the transmission part 133 may contact the receiving part 134.
The guide protrusions 122a and 122b may be formed of a material having elasticity. Accordingly, the guide protrusions 122a and 122b may be bent in the direction of the inside of the body 120 when the user presses the button part 132. When the user releases the button part 132, the guide protrusions 122a and 122b may be returned to their initial position, i.e., to their position before pressing the button part 132.
According to another exemplary embodiment, when the user presses the button part 132 with a physical force, only the sliding part 131 may be bent in the direction of the inside of the body 120. Accordingly, the transmission part 133 may be moved to the inside of the body 120 with the sliding part 131 to contact the receiving part 134.
The transmission part 133 may be formed of a conductive material. Accordingly, when the transmission part 133 contacts the receiving part 134, the transmission part 133 and the receiving part 134 may be electrically connected to each other. Furthermore, the receiving part 134, which will be described below, may also be formed of a conductive material.
The receiving part 134 is formed inside the body 120, e.g., on a support 121 inside the body 120. Here, the receiving part 134 contacts the transmission part 133 to transmit an input signal generated through the button part 132 to the inside of the body 120. As described above, the receiving part 134 is electrically connected to the transmission part 133 to transmit the input signal to the inside of the body 120.
According to the first exemplary embodiment, the transmission part 133 and the button part 132 may be disposed facing each other. For example, the transmission part 133 and the button part 132 may be disposed in the vertical direction facing each other.
FIG. 5 illustrates a cross-sectional view of an input part of a portable terminal according to a second exemplary embodiment. Referring to FIG. 5, according to the second exemplary embodiment, an input part 230 may include a sliding part 231, a button part 232, and a transmission part 233.
The sliding part 231 may slide on a lateral circumference of a body 220. The sliding part 231 may be moved along a guide formed on a side 222 of the body 220. According to the second exemplary embodiment, the guide may include guide grooves 222a and 222b in the side 222 of the body 220, as shown in FIG. 5.
A guide protrusion 235 slidably combined with the guide grooves 222a and 222b may be formed at the side of the sliding part 231. For example, the guide protrusion 235 may be formed along the side of the sliding part 231, and may correspond to the guide grooves 222a and 222b in the body 220. As shown in FIG. 5, the guide protrusion 235 may be inserted into the guide grooves 222a and 222b, and may slide along the guide grooves 222a and 222b. 
According to the second exemplary embodiment, the button part 232 may be formed at one side of the sliding part 231. For example, the button part may be formed on a top surface of the sliding part 231. For example, the button part may be flush with the top surface of the sliding part 231 and marked with a symbol, e.g., in FIG. 5 the button part is below the arrow on the top surface of the sliding part 231. However, the button part is not limited thereto, e.g., the button part may be formed on the sliding part 231 in a protruding shape.
Referring to FIG. 6, when the user applies a physical force to the button part in order to press the button part, the sliding part 231 may be bent in the direction of the inside of the body. Accordingly, a transmission part 233 may be moved toward the inside of the body, e.g., toward a support 221 inside the body, to contact a receiving part 234.
FIG. 7 illustrates a perspective view of an input part of a portable terminal according to a third exemplary embodiment.
According the third exemplary embodiment, a button part 332 may be a touch switch. For example, the button part 332 may be a capacitive or a resistive touch switch.
For example, when the button part 332 is implemented as a capacitive touch switch, the user may touch the button part 332 formed at one side of a sliding part 331 with a finger, without applying a physical force thereto, such that an input signal from the user may be transmitted to the inside of the body of the portable terminal. In another example, if the button part 332 is implemented as a resistive touch switch, a transmission part 333 contacts the receiving part when the user touches the button part 332 with a finger or pen, e.g., it is determined whether to transmit an input signal by detecting a resistance variation at the contact position. Any suitable capacitive or resistive touch switch may be employed as the button part, and thus a detailed description thereof is omitted.
According to embodiments, a portable terminal may include a movable input part, so the position of the input part may be changed to a desired position of a user. Such a portable terminal may be conveniently used, since the user may freely move the input part disposed in the body of the portable terminal to a desired position. In contrast, a conventional portable terminal includes a function button fixed to a specific position, so a user has to use the fixed function button even if the position is inconvenient due to, e.g., different hand sizes or different patterns of use.
Example embodiments have been disclosed herein, and although specific terms are employed, they are used and are to be interpreted in a generic and descriptive sense only and not for purpose of limitation. In some instances, as would be apparent to one of ordinary skill in the art as of the filing of the present application, features, characteristics, and/or elements described in connection with a particular embodiment may be used singly or in combination with features, characteristics, and/or elements described in connection with other embodiments unless otherwise specifically indicated. Accordingly, it will be understood by those of skill in the art that various changes in form and details may be made without departing from the spirit and scope of the example embodiments as set forth in the following claims.
