Hereinafter, a portable terminal having a push-type input device related to the present invention will be described in detail with reference to the drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations, and the description thereof is replaced with the first explanation.

1 is a perspective view of a portable terminal according to an embodiment of the present invention.

The portable terminal of the present invention includes a first body 10 and a second body 20 that is slidable along at least one direction on the first body 10. In this figure, the sliding is performed along the sliding direction S substantially perpendicular to the longitudinal direction of the first body 10. The state in which the first body 10 is disposed in a state of being overlapped with the second body 20 may be referred to as a closed configuration and the first body 10 may be referred to as a second body 20 ) May be referred to as an open configuration.

The portable terminal operates mainly in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The portable terminal operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

A casing (a casing, a housing, a cover, etc.) constituting an outer appearance of the first body 10 is formed by a front case 11 and a rear case 12. Various electronic components are embedded in the space formed by the front case 11 and the rear case 12. [ At least one intermediate case may be additionally disposed between the front case 11 and the rear case 12. [ The cases may be formed by injection molding of a synthetic resin or may be formed of a metal material such as stainless steel (STS) or titanium (Ti).

The display section 13, the sound output section 14, the first image input section 15, the first operation section 16, and the sound input section 17 are arranged in the first body 10, specifically the front case 11 .

The display unit 13 includes a liquid crystal display (LCD) module, an OLED (Organic Light Emitting Diode) module, and the like that visually express information. The display unit 13 may further include a touch screen to enable information input by a user's touch.

The sound output unit 14 may be implemented in the form of a receiver or a speaker. The first image input unit 15 may be implemented as a camera module for capturing an image or a moving image of a user. The first operating unit 16 receives a command for controlling the operation of the portable terminal according to an exemplary embodiment of the present invention. The sound input unit 17 may be implemented in the form of a microphone, for example, in order to receive voice, sound, etc. of the user.

The front case 21 and the rear case 22 can form the case of the second body 20 as in the case of the first body 10.

The second operation unit 23 may be disposed on the front surface of the second body 20, specifically, the front case 21. [ At least one of the front case 21 and the rear case 22 may be provided with a third operating portion 24 and an interface 26. [

The first to third operating portions 16, 23, 24 may be collectively referred to as a manipulating portion and may be employed in any manner as long as the user operates in a tactile manner.

For example, the operation unit may be implemented as a dome switch or a touch screen or a touch pad capable of receiving commands or information by a push or touch operation of a user, or may be a wheel, a jog type, a joystick, Or the like.

In terms of functions, the first operation unit 16 is for inputting commands such as start, end, scrolling and the like, and the second operation unit 23 may be for inputting numbers, letters, symbols, and the like. The third operation unit 24 may operate as a hot-key for performing a special function such as activation of the first image input unit 15. [

In this embodiment, at least one of the operating portions 16, 23, and 24, for example, the second operating portion 23, may be implemented as a push-type input device operated by the user's pressing operation. Furthermore, the second operating portion 23 may be formed to have a QWERTY arrangement.

The interface 26 is a path through which the portable terminal related to the present invention can exchange data with an external device. For example, the interface 26 may be a wired or wireless connection terminal for connecting to an earphone, a port for short range communication (for example, an IrDA port, a Bluetooth port, a wireless LAN port a wireless Lan port), or power supply terminals for supplying power to the portable terminal. The interface 26 may be a card socket that accepts an external card such as a subscriber identification module (SIM) or a user identity module (UIM), a memory card for information storage, and the like.

A power supply unit 27 for supplying power to the portable terminal is mounted on the rear case 22 side. The power supply unit 27 may be detachably coupled to a rechargeable battery, for example, for charging.

Referring again to FIG. 1, the second operation unit 23 includes a plurality of keys 40 and a frame 50.

The keys 40 may be divided into a plurality of groups, such as numeric key groups, character key groups, and function key groups. For example, numeric key groups include numbers ranging from 0 to 9, character key groups include Korean consonants and vowels or alphabets, and function keys include confirmation keys and direction keys. In this figure, numeric keys 41 for inputting numerals ranging from 0 to 9 are illustrated as keys of a numeric key group, which can be used for entering a telephone number or the like. However, if the number of keys is not large as in the keys 41 of the numeric key group, some of the function keys may be grouped into numeric keys and classified into one key group.

The frame 50 is movably mounted on the second body 20 while mainly covering the front case 21. In the present embodiment, the frame 50 is disposed so as to surround a main surface of the front case 21 and a side surface extending from the main surface.

The frame 50 may have a plate shape. The main surface of the frame 50 includes a first area 51 for allowing the numeric keys 41 to be recognized from the outside and a second area 52 excluding the first area 51.

Fig. 2 is a perspective view showing a state in which the frame 50 of Fig. 1 is deployed along the expansion direction D. Fig.

Referring to this figure, the frame 50 is in a state in which the frame 50 is slidably moved along the unfolding direction D perpendicular to the sliding direction S. However, the sliding direction of the frame 50 is not necessarily limited to the upward direction.

By means of the sliding, other keys 42 than the keys 41 illustrated in FIG. 1 are recognized through the first area 51 of the frame 50. The upper keys 42 are keys for receiving alphabets as character keys, and may be arranged to form a QWERTY arrangement. Using the keys 42 for inputting the upper alphabet, the user can create a text message while viewing the contents output to the display unit 13, or edit contents for sending an e-mail.

By this sliding, the numeric keys 41 previously illustrated in Fig. 1 are obscured by the second area 52 of the frame 50 from being recognized from the outside. As a result, only the keys 41 or 42 corresponding to the operating mode of the terminal are displayed, so that the complexity of the display of a plurality of groups of keys together can be eliminated or mitigated.

Further, unlike the method in which the selection of the keys corresponding to the operation mode is performed through several steps through the menu, the user can easily obtain the desired input environment by performing the intuitive and one-time method of sliding the frame 50 There is an advantage to be able to.

3 is a rear perspective view of the portable terminal of FIG.

Referring to FIG. 3, a second image input unit 28 may be additionally mounted on a rear surface of the rear case 22 of the second body 20. The second image input unit 28 may have a photographing direction substantially opposite to that of the first image input unit 15 (see FIG. 1), and may be a camera having different pixels from the first image input unit 15.

For example, the first image input unit 15 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and send it to the other party. The second image input unit 28 photographs a general object It is often not transmitted, and therefore, it can have a high pixel.

A flash 29 and a mirror 30 are further disposed adjacent to the second image input unit 28. The flash 29 shines light toward the subject when the subject is photographed by the second image input unit 28. The mirror unit 30 allows the user to illuminate the user's own face or the like when the user intends to take a picture of himself / herself (self-photographing) using the second image input unit 28.

The lower cover 22 may further be provided with a second sound output section 31. [ The second sound output unit 31 may implement a stereo function together with the first sound output unit 14 (see FIG. 1), and may be used for talking in a speakerphone mode.

At one side of the lower cover 22, an antenna 32 for reception of a broadcast signal may be arranged in addition to an antenna for communication. The antenna 32 may be installed to be detachable from the second body 20.

A portion of the slide module 33 that slidably couples the first body 10 and the second body 20 is disposed on the rear case 12 side of the first body 10. [ The other part of the slide module 33 is disposed on the side of the front case 21 of the second body 20 and may be in a form that is not exposed to the outside as in this figure.

In the above description, the second image input unit 28 and the like are disposed in the second body 20, but the present invention is not limited thereto. At least one of the configurations 28 to 32 described as being arranged in the lower cover 22, such as the second image input unit 28, may be mounted on the first body 10, mainly the lower cover 12, It is also possible to mount it. In such a case, there is an advantage that the configuration (s) arranged in the lower cover 12 in the closed state is protected by the second body 20. Further, the first image input unit 15 may be rotatably formed so that the second image input unit 28 can be photographed up to the second image input unit 28 even if the second image input unit 28 is not separately provided.

4 is a cross-sectional view of a portion of the second operating portion 23 taken along line (IV-IV) in Fig.

Referring to this figure, the keys 40 include a display unit 71 and a signal generating unit 72.

The display unit 71 displays the signals (commands, information) input to the terminal so that the keys can be visually recognized as the keys 40 are operated. The display unit 71 may include a printed layer on which a pattern (symbol, pattern) for informing the above signals is printed.

The signal generating section 72 includes a substrate 72b on which the switches 72a are arranged so that a signal is generated as the switch 72a is pressed. The pressing pad 72c provided with the pressing protrusions for facilitating the pressing operation of each switch 72a can be disposed on the switches 72a.

An opening portion 51a is formed in the first region 51 of the frame 50 and the light transmitting key top member 51b may be disposed in the opening portion 51a so as not to be detached from the outside. Alternatively, the key top member 51b may be omitted, and the keys 40 may be directly exposed to the outside through the opening 51a. A support member 56 is disposed below the key top member 51b so that the key top member 51b can be supported so as not to move downward from the opening 51a.

A lubrication member 73 may be disposed between the support member 56 and the display unit 71. [ The lubrication member 73 can mitigate the friction that may occur between the frame 50 and the keys 40 by sliding the frame 50. As the lubrication member 73, an engineering plastic, for example, a member having good lubricity such as POM (Poly Oxy Methylene) may be used. The lubrication member 73 may be directly attached to or coupled to the frame 50 without the support member 56 being separately provided.

According to this configuration, as the key top member 51b is pressed, the switch 72a corresponding thereto is pressed, and a predetermined signal is inputted from the circuit board 72b. The switch 72a corresponding to the second area 52 of the frame 50 is in the standby state until the frame 50 is moved and corresponds to the first area 51. [

5 is a cross-sectional view for explaining a modified example of the second operating portion 23 of Fig.

Referring to FIG. 5, the keys constituting the second operation unit 23 may include a touch screen 80. The touch input unit 81 constituting the touch screen 80 receives a signal according to a touch operation with respect to the first area 51 and the display module 82 displays a signal input by touch. As a result, the touch input unit 81 corresponds to the signal generating unit 72 of the previous embodiment, and the display module 82 corresponds to the display unit 71. [

The lubrication member 83 has the same characteristics as the lubrication member 73 of the foregoing embodiment and can be directly attached to the frame 50 or can be engaged via another member.

6 is an exploded perspective view showing a state in which the frame 50 is separated from the second body 20 of FIG.

Referring to this figure, numeric group keys 41 and character group keys 42 are alternately arranged in the longitudinal direction (corresponding to the expansion direction D) in the front case 21 of the second body 20 .

The frame 50 is in the form of a plate once folded, and the first area 51 and the second area 52 are alternately arranged on the main surface of the frame 50.

The first area 51 has light transmittance so that the corresponding keys 40 are recognized from the outside and the key top member 51b is coupled to the opening 51a as described above with reference to FIG. . The key top member 51b has lower stiffness than the second region 52, so that the user can press the key top member 51b smoothly.

The second region 52, unlike the first region 51, is not light-transmissive so that the corresponding keys 50 are not visible from the outside. The second region 52 also has greater stiffness than the first region 51, so that it is desirable that the keys 40 corresponding thereto are not manipulated even when pressed incorrectly by a user or the like. To this end, even if the second area 52 is pushed, a material having rigidity within a range in which the corresponding keys 40 do not receive a signal can form the second area 52. As a result, the operability of the first area 51 becomes higher than the operability of the second area 52, so that the keys 40 corresponding to the first area 51 are guided to be selectively operated by the user.

A sliding portion 53 protruding to extend along the unfolding direction D is formed on a side of the frame 50 that extends from the main surface thereof. At one point of the sliding portion 53, a projection 55 in the form of a projection is formed.

On the side surface of the second body 20, a guide portion 60 corresponding to the sliding portion 53 of the frame 50 is formed. The guide portion 60 may have the shape of a groove extending along the direction D of deployment. On at least one point of the guide portion 60, detent protrusions 61 are formed to narrow the gap between the grooves. The space defined by these detent protrusions 61 functions as a seat portion 62 on which the projections 55 can be seated.

As the sliding portion 53 moves along the guide portion 60, the frame 50 becomes slidable in the unfolding direction D. As shown in Fig. Further, as the projection 55 is seated in the seating portion 62, the frame 50 can be stopped in at least one position during the sliding.

Although only two types of keys 41 and 42 are illustrated as the keys 40 in the above description, three or more keys may be disposed. In such a case, the first area 51 of the frame 50 may be stopped at a position corresponding to each key, if necessary, by using a mechanism to cause the frame 50 to stop.

Unlike the above-described stop mechanism, it is also possible to arrange the first magnetic element in the sliding portion 53 and arrange the corresponding second magnetic element in the guide portion 60 so as to stop the magnetic attraction have. Here, at least one of the first and second magnetic elements may be a magnet and the other may also be a magnet or a metal member.

7 is a perspective view illustrating a portable terminal according to another embodiment of the present invention.

The first body 10 is slidably coupled to the second body 20 in the sliding direction S 'along the longitudinal direction of the second body 20, unlike the previous embodiment. The frame 90 is deployed along a direction D 'that rotates about an axis substantially perpendicular to the plane defined by the first body 10. The acoustic input section 25 is disposed in the second body 20.

According to such a configuration, a plurality of groups of keys 45 corresponding to the first operating portion 16 'are partially exposed by the rotation of the frame 90, and the other groups are not exposed. Each group of the plurality of groups of keys 45 may be alternately arranged along the upper rotational direction D '.

The upper keys 45 may be arranged such that the function keys such as play, stop, acknowledge, etc. are divided into groups. For example, after the function keys for controlling the music listening function are exposed as the frame 90 is rotated, other function keys for controlling the viewing function of the visual material (movie, moving picture, etc.) may be exposed.

The operation units 16, 23, and 24 are composed of a dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like.

The image input units 15 and 28 process image frames such as still images or moving images obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame is converted into image data that can be displayed on the display unit 13 and output to the display unit 13. [ The image frames processed by the image input units 15 and 28 are stored in the memory 103 under the control of the control unit 100 or transmitted to the outside through the wireless communication module 110. [

The sound input units 17 and 25 receive an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, and the like, and process them as electrical voice data. The processed voice data is converted into a form that can be transmitted to the mobile communication base station through the wireless communication module 110 in the communication mode, and is output to the wireless communication module. In the recording mode, the processed voice data is output to be stored in the memory 103. [ The sound input units 17 and 25 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

The display unit 13 displays and outputs information processed in the portable terminal. For example, when the portable terminal is in the call mode, the control unit 100 displays a UI (User Interface) or GUI (Graphic User Interface) related to the call. When the portable terminal is in the video communication mode or the photographing mode, the control unit 100 displays and displays the photographed image, the UI, and the GUI. When the display unit 13 includes a touch screen, the display unit 13 is used as an input device in addition to the output device.

Also, the sound output units 14 and 31 output sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the portable terminal. These sound output units 14 and 31 include a speaker, a receiver, a buzzer, and the like.

The sensing unit 101 senses the current state of the portable terminal, such as the opening / closing state of the portable terminal, the position of the portable terminal, whether or not the user touches the portable terminal, and generates a sensing signal for controlling the operation of the portable terminal. For example, if the portable terminal is a slide phone type, it senses whether the slide phone is opened or closed, and outputs the sensing result to the controller 100 so that the operation of the terminal is controlled. And a sensing function related to whether or not the power supply unit 27 is powered on, whether the interface 26 is coupled to an external device, and the like.

The interface 26 may be connected to any external device such as a wired / wireless headset, an external charger, a wired / wireless data port, a card socket (for example, a memory card, a SIM / UIM card) It serves as an interface with the device. The interface 26 receives data from an external device or receives power from the external device, transfers the data to each component in the portable terminal, or transmits data in the portable terminal to an external device.

The memory 103 may store a program for processing and controlling the control unit 100 and may store a function for temporary storage of input / output data (for example, a phone book, a message, a still image, . In the memory 103, a program for controlling the operation of the portable terminal related to the present invention is stored. The memory 103 includes a concept of a generally known hard disk, a card type memory (e.g., SD or XD memory), a flash memory, a RAM, a ROM, and the like.

The broadcast receiving module 102 receives a broadcast signal transmitted through a satellite or a terrestrial wave, converts the received broadcast signal into a form of broadcast data that can be output to the sound output unit 14 and the display unit 13, Also, the broadcast receiving module 102 receives additional data (e.g., EPG (Electric Program Guide), channel list, etc.) related to broadcasting. The broadcast data and the additional data converted by the transmission / reception module 102 may be stored in the memory 103. [

The power supply unit 27 receives external power and internal power under the control of the controller 100 and supplies power required for operation of the respective components.

FIG. 9 is a flowchart illustrating an operation mode of the portable terminal of FIG. 1. FIG.

The control unit 100 confirms the opened state through the sensing unit 101 and confirms whether or not the frame 50 is also drawn out (the state shown in FIG. 2).

If the frame 50 is in the drawn state, the keys for the alphabet input 42 are recognizable, so that the control unit 100 can execute the input mode for the character transmission. According to the above-described execution, a character input screen for transmission is output to the display unit 13. If the movement of the frame 50 in the opposite direction to the forward movement direction is detected through the sensing unit 101 so that the frame 50 is in the retracted state (the state of FIG. 1), the control unit 100 may transmit the created character . Depending on the setting, the controller 100 may cause the created character to be stored in the memory 103 during the above movement.

After the frame 50 is in the collapsed state, the keys 41 for numerical input are recognizable by the frame 50. [ In response to these keys 41, the control unit 100 may cause the display unit 13 to output a mode for calling. In this case, the user can press the numeric keys 41 to input the telephone number of the other party and make a telephone call.

If the first body 10 moves in the sliding direction S to be closed, the second operating portion 23 is in a state where it is no longer used. As a result, the control unit 100 ends the control of the operation mode according to the position of the frame 50 in the open terminal.
